Alarm Module: Description and Operation
The Sentry Key Immobilizer Module (SKIM) (1) is the primary component of the Sentry Key
Immobilizer System (SKIS). This module contains a Radio Frequency (RF) transceiver and a
central processing unit, which includes the Sentry Key Immobilizer System (SKIS) program logic.
The SKIM is located on the right side of the steering column, near the ignition lock cylinder housing
and is concealed beneath the steering column shrouds. The molded black plastic housing for the
SKIM has an integral molded plastic halo-like antenna ring (4) that extends from the bottom. When
the SKIM is properly installed on the steering column, the antenna ring is oriented around the
circumference of the ignition lock cylinder housing.
A single integral connector receptacle (3) is located just behind the antenna ring on the bottom of
the SKIM housing. An integral molded plastic mounting tab (2) on the rear corner of the SKIM
housing has a hole in the center through which a screw passes to secure the unit to the steering
column. The SKIM is connected to the vehicle electrical system through a single take out and
connector of the instrument panel wire harness.
The Sentry Key Immobilizer Module (SKIM) transmits Radio Frequency (RF) signals to, and
receives RF signals from the Sentry Key transponder through a tuned antenna enclosed within the
molded plastic antenna ring. If this antenna ring is not mounted properly around the ignition lock
cylinder housing, communication problems between the SKIM and the transponder may arise.
These communication problems will result in Sentry Key transponder-related faults. The SKIM also
communicates over the Programmable Communications Interface (PCI) data bus with the
Powertrain Control Module (PCM) for gasoline engines or the Engine Control Module (ECM) for
diesel engines, the ElectroMechanical Instrument Cluster (EMIC) and/or a diagnostic scan tool.
The SKIM and the PCM/ECM both use software that includes a rolling code algorithm strategy,
which helps to reduce the possibility of unauthorized Sentry Key Immobilizer System (SKIS)
disarming. The rolling code algorithm ensures security by preventing an override of the SKIS
through the unauthorized substitution of the SKIM or the PCM/ECM. However, the use of this
strategy also means that replacement of either the SKIM or the PCM/ECM units will require a
system initialization procedure to restore system operation.
The SKIM retains in memory the ID numbers of any Sentry Key transponder that is programmed
into it. A maximum of eight Sentry Key transponders can be programmed into the SKIM. For added
system security, each SKIM is programmed with a unique Secret Key code. This code is stored in
memory, sent over the PCI data bus to the PCM or ECM, and is encoded to the transponder of
every Sentry Key that is programmed into the SKIM. Therefore, the Secret Key code is a common
element that is found in every component of the SKIS.
Another security code called a PIN, is used to gain access to the SKIM Secured Access Mode. The
Secured Access Mode is required during service to perform the SKIS initialization and Sentry Key
transponder programming procedures. The SKIM also stores the Vehicle Identification Number
(VIN) in its memory, which it learns through a PCI data bus message from the PCM or ECM during
SKIS initialization.
In the event that a SKIM replacement is required, the Secret Key code can be transferred to the
new SKIM from the PCM using a diagnostic scan tool and the SKIS initialization procedure. Proper
completion of the SKIS initialization will allow the existing Sentry Keys to be programmed into the
new SKIM so that new keys will not be required. In the event that the original Secret Key code
cannot be recovered, SKIM replacement will also require new Sentry Keys. The diagnostic scan
tool will alert the technician during the SKIS initialization procedure if new Sentry Keys are
required.
When the ignition switch is turned to the On or Start positions, the SKIM transmits an RF signal to
excite the transponder in the ignition key. The SKIM then listens for a return RF signal from the
transponder. If the SKIM receives an RF signal with a valid "Secret Key" and transponder
identification codes, the SKIM sends a "valid key" message to the PCM/ECM over the PCI bus. If
the SKIM receives an invalid RF signal or no response, it sends "invalid key" messages to the
PCM/ECM. The PCM/ECM will enable or disable engine operation based upon the status of the
SKIM messages. It is important to note that the default condition in the PCM or ECM is an invalid
key. Therefore, if no message is received from the SKIM by the PCM or ECM, the engine will be
disabled and the vehicle immobilized after two seconds of running.

Module, (Vehicle Antitheft) > Component Information > Description and Operation > Page 7
The SKIM also sends electronic messages to the EMIC which control the VTSS indicator. The
SKIM sends messages to the EMIC to turn the indicator on for about three seconds when the
ignition switch is turned to the On position as a bulb test. After completion of the bulb test, the
SKIM sends bus messages to keep the indicator off for a duration of about one second. Then the
SKIM sends messages to turn the indicator on or off based upon the results of the SKIS self-tests.
If the VTSS indicator comes on and stays on after the bulb test, it indicates that the SKIM has
detected a system malfunction and/or that the SKIS has become inoperative.
If the SKIM detects an invalid key when the ignition switch is turned to the On position, it sends
messages to flash the VTSS indicator. The SKIM can also send messages to flash the indicator
and to generate a single audible chime whenever the Customer Learn programming mode is being
utilized.
The SKIS will store fault information in the form of Diagnostic Trouble Codes (DTC's) in SKIM
memory if a system malfunction is detected. For diagnosis or initialization of the SKIM and the
PCM/ECM, a diagnostic scan tool is required.

Keyless Entry Module: Description and Operation
When an RKE lock message is sent to the instrument cluster, the instrument cluster actuates the
door locks, the interior lighting is turned off, the horn chirps (if this feature is enabled), the park
lamps flash (if this feature is enabled) and, if the vehicle is so equipped, the Vehicle Theft Security
System (VTSS) is armed. When an RKE unlock message is sent to the instrument cluster, the
instrument cluster actuates the driver side front door (or all doors if this feature is enabled) unlock,
the interior lighting is turned on and, if the vehicle is so equipped, the VTSS is disarmed.
When an RKE panic message is sent to the instrument cluster, the instrument cluster actuates the
driver side front door (or all doors if this feature is enabled) unlock, the interior lighting is turned on
and, if the vehicle is so equipped, the VTSS is disarmed. The panic message will also cause the
exterior lamps (including the headlights) to flash, and the horn to sound for about three minutes, or
until a second panic message is sent to the instrument cluster. A vehicle speed of about 25.7
kilometers-per-hour (15 miles-per-hour) will also cancel the panic event.
Whenever the vehicle battery power is interrupted, the Remote Keyless Module (RKE) Module will
retain all vehicle access codes in its memory. When replacing or adding a key fob transmitter
(maximum of 4) a scan tool is required to program the RKE Module to accept the new Vehicle
Access Code if a customer owned transmitter is not available.

RELAY PACK
DESCRIPTION
Relay Pack
Electrical operation of the control assembly consists of four heavy duty relays, a thermal-switch
located on the motor armature brush holder and a Low Voltage Interrupt (LVI) located in the control
assembly. The thermal-switch interrupts the power-in function and the LVI affects both the power-in
and power-out functions and must be reset by allowing the charging circuit voltage to rise above 10
volts for more than 30 seconds. The thermal switch is reset only by allowing the winch motor to
cool adequately (about 30 minutes). Relay number 1 and 3 control current flow through the field
windings and relay number 2 and 4 supply current to the motor armature.
OPERATION
In the power-out mode, relay number 2 and 3 are energized by the remote control switch. Current
flows from the positive battery terminal through relay number 3 then through the black motor cable
to the number 2 and number 1 field windings. From the black motor cable current then flows
through solenoid number 2 to the motor armature to ground.
In power-in mode, relay number 1 and 4 are energized. Current again flows from the battery
positive cable, but this time current flows through solenoid number 1 then through field winding
number 1. Current flowing in the reverse direction through the field windings cause the motor to
turn in the opposite direction. From the red motor cable current then flows through relay number 4
to the black cable going to the motor armature to ground.

Heated Mirror Relay: Description and Operation
The heated mirror relay (1) is a International Standards Organization (ISO)-type relay. Relays
conforming to the ISO specifications have common physical dimensions, current capacities,
terminal functions and patterns (2). The heated mirror relay is a electromechanical device that
switches battery current through a fuse in the integrated power module (IPM) to the outside rear
view mirror heating grids. The heated mirror relay is energized when the relay coil is provided a
ground path by the control circuitry within the A/C-heater control.
The heated mirror relay is located in the IPM in the engine compartment.
The ISO-standard heated mirror relay is an electromechanical switch that uses a low current input
controlled by the A/C-heater control to control the high current output to the outside rear view mirror
heating grids. The movable, common feed relay contact is held against the fixed, normally closed
relay contact by spring pressure. When the electromagnetic relay coil is energized, it draws the
movable common feed relay contact away from the fixed, normally closed relay contact and, holds
it against the fixed, normally open relay contact. This action allows high current to flow to the
outside rear view mirror heating grids.
When the relay coil is de-energized, spring pressure returns the movable relay contact back
against the fixed, normally closed contact point. The resistor or diode is connected in parallel with
the relay coil, and helps to dissipate voltage spikes and electromagnetic interference that can be
generated as the electromagnetic field of the relay coil collapses.
The heated mirror relay terminals are connected to the vehicle electrical system through a
receptacle in the integrated power module (IPM). The inputs and outputs of the heated mirror relay
include:
- Terminal (30) receives fused battery current at all times.
- Terminal (86) receives a ground through the defogger relay control circuit only when the
A/C-heater control electronically pulls the circuit to ground.
- Terminal (85) receives fused battery current through an ignition switch output circuit only when
the ignition switch is in the Run position.
- Terminal (87) provides battery current to the heated outside rear view mirror grids through the
heated mirror relay output circuit only when the heated mirror relay coil is energized.
- Terminal (87A) is not connected to any circuit in this application, but provides a battery current
output only when the heated mirror relay coil is de-energized.
The heated mirror relay cannot be repaired and, if faulty or damaged, it must be replaced. Refer to
the appropriate wiring information for diagnosis and testing of the ISO-standard relay and for
complete heated mirror system wiring diagrams.

Power Seat Control Module: Description and Operation
The heated seat module (2) is also known as the Seat Heat Interface Module. The heated seat
module is located under the drivers front seat cushion, where it is secured to a mounting bracket.
The heated seat module has a single connector receptacle (3) that allows the module to be
connected to all of the required inputs and outputs through the seat wire harness.
The heated seat module is an electronic microprocessor controlled device designed and
programmed to use inputs from the battery, the two heated seat switches and the two heated seat
sensors to operate and control the heated seat elements in both front seats and the two heated
seat indicator lamp Light-Emitting Diodes (LEDs) in each heated seat switch. The heated seat
module is also programmed to perform self-diagnosis of certain heated seat system functions and
provide feedback of that diagnosis through the heated seat switch indicator lamps.
The heated seat module cannot be repaired. If the heated seat module is damaged or faulty, the
entire module must be replaced.
The heated seat module operates on fused battery current received from the integrated power
module. Inputs to the module include a resistor multiplexed heated seat switch request circuit for
each of the two heated seat switches and the heated seat sensor inputs from the seat cushions of
each front seat. In response to those inputs the heated seat module controls battery current feeds
to the heated seat elements and sensors, and controls the ground for the heated seat switch
indicator lamps.
When a heated seat switch (Driver or Passenger) is depressed a signal is received by the heated
seat module, the module energizes the proper indicator LED (Low or High) in the switch by
grounding the indicator lamp circuit to indicate that the heated seat system is operating. At the
same time, the heated seat module energizes the selected heated seat sensor circuit and the
sensor provides the module with an input indicating the surface temperature of the selected seat
cushion.
The Low heat set point is about 36° C (96.8° F), and the High heat set point is about 42°C (107.6°
F). If the seat cushion surface temperature input is below the temperature set point for the selected
temperature setting, the heated seat module energizes an N-channel Field Effect Transistor
(N-FET) within the module which energizes the heated seat elements in the selected seat cushion
and back. When the sensor input to the module indicates the correct temperature set point has
been achieved, the module de-energizes the N-FET which de-energizes the heated seat elements.
The heated seat module will continue to cycle the N-FET as needed to maintain the selected
temperature set point.
If the heated seat module detects a heated seat sensor value input that is out of range or a shorted
or open heated seat element circuit, it will notify the vehicle operator or the repair technician of this
condition by flashing the High and/or Low indicator lamps in the affected heated seat switch.

Seat Heater Control Module: Description and Operation
The heated seat module (2) is also known as the Seat Heat Interface Module. The heated seat
module is located under the drivers front seat cushion, where it is secured to a mounting bracket.
The heated seat module has a single connector receptacle (3) that allows the module to be
connected to all of the required inputs and outputs through the seat wire harness.
The heated seat module is an electronic microprocessor controlled device designed and
programmed to use inputs from the battery, the two heated seat switches and the two heated seat
sensors to operate and control the heated seat elements in both front seats and the two heated
seat indicator lamp Light-Emitting Diodes (LEDs) in each heated seat switch. The heated seat
module is also programmed to perform self-diagnosis of certain heated seat system functions and
provide feedback of that diagnosis through the heated seat switch indicator lamps.
The heated seat module cannot be repaired. If the heated seat module is damaged or faulty, the
entire module must be replaced.
The heated seat module operates on fused battery current received from the integrated power
module. Inputs to the module include a resistor multiplexed heated seat switch request circuit for
each of the two heated seat switches and the heated seat sensor inputs from the seat cushions of
each front seat. In response to those inputs the heated seat module controls battery current feeds
to the heated seat elements and sensors, and controls the ground for the heated seat switch
indicator lamps.
When a heated seat switch (Driver or Passenger) is depressed a signal is received by the heated
seat module, the module energizes the proper indicator LED (Low or High) in the switch by
grounding the indicator lamp circuit to indicate that the heated seat system is operating. At the
same time, the heated seat module energizes the selected heated seat sensor circuit and the
sensor provides the module with an input indicating the surface temperature of the selected seat
cushion.
The Low heat set point is about 36° C (96.8° F), and the High heat set point is about 42° C (107.6°
F). If the seat cushion surface temperature input is below the temperature set point for the selected
temperature setting, the heated seat module energizes an N-channel Field Effect Transistor
(N-FET) within the module which energizes the heated seat elements in the selected seat cushion
and back. When the sensor input to the module indicates the correct temperature set point has
been achieved, the module de-energizes the N-FET which de-energizes the heated seat elements.
The heated seat module will continue to cycle the N-FET as needed to maintain the selected
temperature set point.
If the heated seat module detects a heated seat sensor value input that is out of range or a shorted
or open heated seat element circuit, it will notify the vehicle operator or the repair technician of this
condition by flashing the High and/or Low indicator lamps in the affected heated seat switch.

Compressor Clutch Relay: Description and Operation
The A/C clutch relay (1) is a International Standards Organization (ISO) micro-relay. Relays
conforming to the ISO specifications have common physical dimensions, current capacities,
terminal functions and patterns (2). The ISO micro-relay terminal functions are the same as a
conventional ISO relay. However, the ISO micro-relay terminal pattern (or footprint) is different, the
current capacity is lower, and the physical dimensions are smaller than those of the conventional
ISO relay
The A/C clutch relay is located in the integrated power module (IPM) in the engine compartment.
The ISO-standard A/C clutch micro-relay is an electromechanical switch that uses a low current
input from the powertrain control module (PCM) or engine control module (ECM) (depending on
engine application), to control the high current output to the A/C clutch field coil. The movable,
common feed relay contact is held against the fixed, normally closed relay contact by spring
pressure. When the electromagnetic relay coil is energized, it draws the movable common feed
relay contact away from the fixed, normally closed relay contact and, holds it against the fixed,
normally open relay contact. This action allows high current to flow to the A/C clutch field coil.
When the relay coil is de-energized, spring pressure returns the movable relay contact back
against the fixed, normally closed contact point. The resistor or diode is connected in parallel with
the relay coil, and helps to dissipate voltage spikes and electromagnetic interference that can be
generated as the electromagnetic field of the relay coil collapses.
The A/C clutch relay terminals are connected to the vehicle electrical system through a receptacle
in the integrated power module (IPM). The inputs and outputs of the A/C clutch relay include:
- The common feed terminal (30) receives a battery current input from a fuse in the IPM through a
fused B(+) circuit at all times.
- The coil ground terminal (86) receives a ground input from the PCM/ECM through the A/C clutch
relay control circuit only when the PCM/ECM electronically pulls the circuit to ground.
- The coil battery terminal (85) receives a battery current input from PTC 1 in the IPM through a
fused ignition switch output (run) circuit only when the ignition switch is in the On position.
- The normally open terminal (87) provides a battery current output to the A/C clutch coil through
the A/C clutch relay output circuit only when the A/C clutch relay coil is energized.
- The normally closed terminal (87A) is not connected to any circuit in this application, but provides
a battery current output only when the A/C clutch relay coil is de-energized.
The A/C clutch relay cannot be repaired and, if faulty or damaged, it must be replaced. Refer to the
appropriate wiring information for diagnosis and testing of the ISO-standard micro-relay and for
complete HVAC wiring diagrams.

The front fog lamp relay is an electromechanical switch that uses a low current input from the Front
Control Module (FCM) (also referred to as the Integrated Power Module/IPM) to control a high
current output to the front fog lamps. Within the relay are an electromagnetic coil, a movable
contact and two fixed contact points. A resistor is connected in parallel with the coil, and helps to
dissipate voltage spikes and electromagnetic interference that can be generated as the field of the
relay coil collapses.
The movable common supply contact point is held against the fixed normally closed contact point
by spring pressure. When the relay coil is energized, an electromagnetic field is produced by the
coil windings. This field draws the movable contact away from the normally closed contact, and
holds it against the normally open contact. When the relay coil is de-energized, spring pressure
returns the movable contact back against the normally closed contact.
The inputs and outputs of the front fog lamp relay include:
- Common Supply Terminal (30) - The common feed terminal is connected to a fused B(+) circuit at
all times.
- Coil Ground Terminal (85) - The coil ground terminal is connected to a fused B(+) circuit at all
times.
- Coil Battery Terminal (86) - The coil battery terminal is connected to a control output of the FCM
through a fog lamp relay control circuit. The FCM controls front fog lamp operation by controlling a
ground path through this circuit.
- Normally Open Terminal (87) - The normally open terminal is connected to the front fog lamps
through a fog lamp relay output circuit and provides battery voltage to the front fog lamps whenever
the relay is energized.
- Normally Closed Terminal (87A) - The normally closed terminal is not connected to any circuit in
this application, but will have battery voltage present whenever the relay is de-energized.
The front fog lamp relay can be diagnosed using conventional diagnostic tools and methods.

Power Distribution Module: Testing and Inspection
FRONT CONTROL MODULE
The Front Control Module (FCM) is a printed circuit board based module with a on-board
micro-processor. The FCM interfaces with other electronic modules in the vehicle via the
Programmable Communications Interface (PCI) data bus. In order to obtain conclusive testing the
PCI data bus network and all of the electronic modules that provide inputs to, or receive outputs
from the FCM must be checked. All PCI communication faults must be resolved prior to further
diagnosing any FCM related issues.
The FCM was designed to be diagnosed with an appropriate diagnostic scan tool. The most
reliable, efficient, and accurate means to diagnose the FCM requires the use of an appropriate
scan tool and the proper Diagnostic Procedures.
Before any testing of the FCM is attempted, the battery should be fully charged and all wire
harness and ground connections inspected around the affected areas on the vehicle.

Power Distribution Relay: Description and Operation
RELAY-TRAILER TOW
All vehicles are equipped with two trailer tow relays, one for the trailer right turn and brake lamps
and the other for the trailer left turn and brake lamps. The trailer tow relays are conventional
International Standards Organization (ISO) micro relays. Relays conforming to the ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions. Each relay is contained within a small, rectangular, molded plastic housing and
is connected to all of the required inputs and outputs through five integral male spade-type
terminals that extend from the relay base plate.
The trailer tow relays are located in the Power Distribution Center (PDC) in the engine
compartment near the battery. Refer to the layout label on the underside of the PDC cover for
specific relay cavity assignment information. A trailer tow relay cannot be adjusted or repaired and,
if faulty or damaged, the unit must be replaced.
The trailer tow relays are electromechanical switches that use a low current input from the Front
Control Module (FCM) (also referred to as the Integrated Power Module/IPM) to control a high
current output to trailer brake and turn signal lamps. Within each relay are an electromagnetic coil,
a movable contact and two fixed contact points. A resistor is connected in parallel with the coil, and
helps to dissipate voltage spikes and electromagnetic interference that can be generated as the
field of the relay coil collapses.
The movable common supply contact point is held against the fixed normally closed contact point
by spring pressure. When the relay coil is energized, an electromagnetic field is produced by the
coil windings. This field draws the movable contact away from the normally closed contact, and
holds it against the normally open contact. When the relay coil is de-energized, spring pressure
returns the movable contact back against the normally closed contact.
The inputs and outputs of the trailer tow relays include:
- Common Supply Terminal (30) - The common feed terminal is connected to a fused B(+) circuit at
all times.
- Coil Ground Terminal (85) - The coil ground terminal is connected to a fused B(+) circuit at all
times.
- Coil Battery Terminal (86) - The coil battery terminal is connected to a control output of the FCM
through a right or left trailer tow turn relay control circuit. The FCM controls trailer brake and turn
lamp operation by controlling a ground path through this circuit.
- Normally Open Terminal (87) - The normally open terminal is connected to the trailer lamps
through a right or left trailer tow turn relay output circuit and provides battery voltage to the right or
left trailer brake and turn lamps whenever the relay is energized.
- Normally Closed Terminal (87A) - The normally closed terminal is not connected to any circuit in
this application, but will have battery voltage present whenever the relay is de-energized.
The trailer tow relays can be diagnosed using conventional diagnostic tools and methods.

Body Control Module: Description and Operation
The Front Control Module (FCM) is a micro controller located in the left front corner of the engine
compartment. It is necessary to position the Integrated Power Module (IPM) aside in order to
access the front control module on this vehicle. The FCM mates to the Power Distribution Center
(PDC) to form the IPM. The IPM connects directly to the battery and provides the primary means of
circuit protection and power distribution for all vehicle electrical systems. The FCM controls power
to some of the vehicle systems electrical and electromechanical loads based on inputs received
from hard wired switch inputs and data received on the PCI bus circuit.
As messages are sent over the Programmable Communications Interface (PCI) data bus circuit,
the Front Control Module (FCM) reads these messages and controls power to some of the vehicles
electrical systems by completing the circuit to ground (low side driver) or completing the circuit to
12 volt power (high side driver). The following functions are Controlled by the FCM:
- Headlamp Power with Voltage Regulation
- Windshield Wiper "ON/OFF" Relay Actuation
- Windshield Wiper "HI/LO" Relay Actuation
- Windshield Washer Pump Motor
- Fog Lamp Relay Actuation
- Park Lamp Relay Actuation
- Horn Relay Actuation
The following inputs are Received/Monitored by the FCM:
- B+ Connection Detection
- Power Ground
- Ambient Temperature Sensing
- Ignition Switch Run
- Washer Fluid Level Switch
- Windshield Wiper Park Switch
- PCI Data Bus Circuit

A/C Status Indicator Flashing
A/C STATUS INDICATOR FLASHING
Theory of Operation
Running the AC Cooldown test will cause the A/C status indicator to flash. If the test fails, the
status indicator will continue to flash until either the test returns passed or the ignition key is cycled.
When the A/C status indicator is flashing, it will not indicate A/C operating status. However, the A/C
mode switch will continue to function normally. For vehicles equipped with EBL, when the A/C
status indicator is flashing, the EBL status indicator will not function. However, the EBL mode
switch will continue to function normally.
POSSIBLE CAUSES
- A/C Cooldown test failed
1. PERFORM THE A/C COOLDOWN TEST
NOTE: The following are prerequisites of the Cooldown Test. Verify each of the following before
running the test:
- Verify that no Evaporator Temperature Sensor related DTCs are not active. If active, diagnose
and repair the DTC before proceeding.
- Verify that the refrigerant system has an adequate charge. Check and repair as necessary before
proceeding.
- Verify that the blower motor operates correctly in all speeds. Diagnose and repair all blower
related faults before proceeding.
- Verify that the work area ambient temperature is above 21.1° C (70° F) before proceeding. Move
the vehicle to a warmer work area if necessary.
- Verify that the evaporator temperature is above 12.7° C (55° F) before proceeding.

Actuator Circuit Test Diagnostics (Dual-Zone)
Theory of Operation
By running the Actuator Circuit Test, the A/C Heater Control can identify up to three door driver
circuits shorted simultaneously. A Short Too Complex fault will set if more than three door driver
circuits are shorted in the same direction (e.g. four door driver circuits all shorted to ground) or if
two or more door driver circuits are shorted with at least one door driver circuit shorted to ignition
and one door driver circuit shorted to ground. Fault messages displaying XXX Driver/Circuit
Shorted to Ignition/Battery and XXX Driver/Circuit Shorted to Ground will set on a per-driver basis.

EBL Status Indicator Flashing
EBL STATUS INDICATOR FLASHING
Theory of Operation
Running the HVAC Door Recalibration will cause the EBL status indicator to flash. If recalibration
fails, the status indicator will continue to flash until either the system passes recalibration or the
ignition key is cycled. When the EBL status indicator is flashing, it will not indicate EBL operating
status. However, the EBL mode switch will continue to function normally. When the EBL status
indicator is flashing, the A/C status indicator will not function. However, the A/C mode switch will
continue to function normally.
POSSIBLE CAUSES

NOTE:
Refer to the table for specific applications.
DISCUSSION:
Mopar(R) is currently phasing out pre-programmed PCMs for the vehicles listed. New modules will
no longer be pre-programmed when received from Mopar(R). Replacement of future PCMs will
require programming utilizing the DRBIII(R) and TechCONNECT. The PCM will not operate the
engine until it is programmed. A Diagnostic Trouble Code (DTC) will be set - "not programmed".
CAUTION:
Extreme care must be taken when programming a calibration into a generic PCM. Do not randomly
select a calibration. Once a calibration is selected and programmed, the controller cannot be
reprogrammed to a different calibration. The module can only be reprogrammed to a more recent
version of that calibration.

PARTS REQUIRED:
SPECIAL TOOLS/EQUIPMENT REQUIRED:
NOTE:
An updated J1962 cable has been released. This cable has a red colored connector at the
DRBIII(R) connection. Use this cable whenever a flash is being performed.
REPAIR PROCEDURE:
NOTE:
When flashing a 2002 - 2004 LH vehicle the BCM may need to be disconnected if experiencing
failures during the flash of the transmission portion of the PCM. The BCM will need to be
disconnected after the module ID portion of the flash is complete. Before pressing Page Forward to
begin the flash of the PCM Turn the Key to the OFF position and disconnect the BCM. Then turn
the KEY to the RUN position and Press Page Forward to begin the PCM flash session.
NOTE:
If vehicle is a DAKOTA, then the ABS CAB module connector MUST be disconnected prior to
performing this Repair Procedure. The CAB module and the PCM are connected at the same
diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB
module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is
complete turn the ignition switch to the OFF position, connect the CAB module connector, and then
check for any erroneous DTC's. If the PCM becomes "locked" during reprogramming because the
ABS CAB module connector was not disconnected, then the PCM may be recovered by following
the procedure in this NOTE.
NOTE:
Whenever a controller is programmed, the software in the DRBIII(R); must be programmed with the
latest revision level available.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted and then follow the
directions on the DRBIII(R).
1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from
the DRBIII(R) memory. To clear the memory from the MAIN MENU power up the DRBIII(R) and
then:
a. Simultaneously press the "MORE" and "YES" keys.
b. A screen will appear requesting a "COLD BOOT".
c. Follow the on screen instructions by selecting the "F4" key.
d. When the DRB III(R) reboots to the MAIN MENU, proceed to Step 2.

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.
2007 GRAND CHEROKEE W/ 3.0L TD/2005 - 2007 LIBERTY w/2.8L TD/2007 RAM TRUCK/RAM
CAB CHASSIS w 6.7L TD AND 2004-2006 SPRINTER w 2.7L TD ENGINES.
For the above models equipped with Turbo Diesel Engines, the fuel injector "Quantity Values" must
be physically read from each injector and the values written to the ECU with an appropriate scan
tool.

PCMs > Page 326
NOTE:
Refer to the table for specific applications.
DISCUSSION:
Mopar(R) is currently phasing out pre-programmed PCMs for the vehicles listed. New modules will
no longer be pre-programmed when received from Mopar(R). Replacement of future PCMs will
require programming utilizing the DRBIII(R) and TechCONNECT. The PCM will not operate the
engine until it is programmed. A Diagnostic Trouble Code (DTC) will be set - "not programmed".
CAUTION:
Extreme care must be taken when programming a calibration into a generic PCM. Do not randomly
select a calibration. Once a calibration is selected and programmed, the controller cannot be
reprogrammed to a different calibration. The module can only be reprogrammed to a more recent
version of that calibration.

PARTS REQUIRED:
SPECIAL TOOLS/EQUIPMENT REQUIRED:
NOTE:
An updated J1962 cable has been released. This cable has a red colored connector at the
DRBIII(R) connection. Use this cable whenever a flash is being performed.
REPAIR PROCEDURE:
NOTE:
When flashing a 2002 - 2004 LH vehicle the BCM may need to be disconnected if experiencing
failures during the flash of the transmission portion of the PCM. The BCM will need to be
disconnected after the module ID portion of the flash is complete. Before pressing Page Forward to
begin the flash of the PCM Turn the Key to the OFF position and disconnect the BCM. Then turn
the KEY to the RUN position and Press Page Forward to begin the PCM flash session.
NOTE:
If vehicle is a DAKOTA, then the ABS CAB module connector MUST be disconnected prior to
performing this Repair Procedure. The CAB module and the PCM are connected at the same
diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB
module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is
complete turn the ignition switch to the OFF position, connect the CAB module connector, and then
check for any erroneous DTC's. If the PCM becomes "locked" during reprogramming because the
ABS CAB module connector was not disconnected, then the PCM may be recovered by following
the procedure in this NOTE.
NOTE:
Whenever a controller is programmed, the software in the DRBIII(R); must be programmed with the
latest revision level available.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted and then follow the
directions on the DRBIII(R).
1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from
the DRBIII(R) memory. To clear the memory from the MAIN MENU power up the DRBIII(R) and
then:
a. Simultaneously press the "MORE" and "YES" keys.
b. A screen will appear requesting a "COLD BOOT".
c. Follow the on screen instructions by selecting the "F4" key.
d. When the DRB III(R) reboots to the MAIN MENU, proceed to Step 2.

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.

Engine Control Module: Description and Operation PCM
The Powertrain Control Module (PCM) is located in the right-rear section of the engine
compartment under the cowl.
Two different PCM's are used (JTEC and NGC). These can be easily identified. JTEC's use three
32-way connectors, NGC's use four 38-way connectors.
The PCM operates the fuel system. The PCM is a pre-programmed, triple microprocessor digital
computer. It regulates ignition timing, air-fuel ratio, emission control devices, charging system,
certain transmission features, speed control, air conditioning compressor clutch engagement and
idle speed. The PCM can adapt its programming to meet changing operating conditions.
The PCM receives input signals from various switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operations through different system components. These
components are referred to as Powertrain Control Module (PCM) Outputs. The sensors and
switches that provide inputs to the PCM are considered Powertrain Control Module (PCM) Inputs.
The PCM adjusts ignition timing based upon inputs it receives from sensors that react to: engine
rpm, manifold absolute pressure, engine coolant temperature, throttle position, transmission gear
selection (automatic transmission), vehicle speed, power steering pump pressure, and the brake
switch.
The PCM adjusts idle speed based on inputs it receives from sensors that react to: throttle position,
vehicle speed, transmission gear selection, engine coolant temperature and from inputs it receives
from the air conditioning clutch switch and brake switch.
Based on inputs that it receives, the PCM adjusts ignition coil dwell. The PCM also adjusts the
generator charge rate through control of the generator field and provides speed control operation.

Engine Control Module: Description and Operation Modes of Operation
As input signals to the Powertrain Control Module (PCM) change, the PCM adjusts its response to
the output devices. For example, the PCM must calculate different injector pulse width and ignition
timing for idle than it does for wide open throttle (WOT).
The PCM will operate in two different modes: Open Loop and Closed Loop.
During Open Loop modes, the PCM receives input signals and responds only according to preset
PCM programming. Input from the oxygen (02S) sensors is not monitored during Open Loop
modes.
During Closed Loop modes, the PCM will monitor the oxygen (02S) sensors input. This input
indicates to the PCM whether or not the calculated injector pulse width results in the ideal air-fuel
ratio. This ratio is 14.7 parts air-to-1 part fuel. By monitoring the exhaust oxygen content through
the 02S sensor, the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance.
The fuel injection system has the following modes of operation:
- Ignition switch ON
- Engine start-up (crank)
- Engine warm-up
- Idle
- Cruise
- Acceleration
- Deceleration
- Wide open throttle (WOT)
- Ignition switch OFF
The ignition switch On, engine start-up (crank), engine warm-up, acceleration, deceleration and
wide open throttle modes are Open Loop modes. The idle and cruise modes, (with the engine at
operating temperature) are Closed Loop modes.
IGNITION SWITCH (KEY-ON) MODE
This is an Open Loop mode. When the fuel system is activated by the ignition switch, the following
actions occur:
- The PCM pre-positions the idle air control (IAC) motor.
- The PCM determines atmospheric air pressure from the MAP sensor input to determine basic fuel
strategy.
- The PCM monitors the engine coolant temperature sensor input. The PCM modifies fuel strategy
based on this input.
- Intake manifold air temperature sensor input is monitored.
- Throttle position sensor (TPS) is monitored.
- The auto shutdown (ASD) relay is energized by the PCM for approximately three seconds.
- The fuel pump is energized through the fuel pump relay by the PCM. The fuel pump will operate
for approximately three seconds unless the engine is operating or the starter motor is engaged.
- The 02S sensor heater element is energized via the ASD or 02S heater relay. The 02S sensor
input is not used by the PCM to calibrate air-fuel ratio during this mode of operation.
ENGINE START-UP MODE
This is an Open Loop mode. The following actions occur when the starter motor is engaged. The
PCM receives inputs from:
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
The PCM monitors the crankshaft position sensor. If the PCM does not receive a crankshaft
position sensor signal within 3 seconds of cranking the engine, it will shut down the fuel injection
system.
The fuel pump is activated by the PCM through the fuel pump relay.
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
The PCM determines the proper ignition timing according to input received from the crankshaft
position sensor.
ENGINE WARM-UP MODE
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Description and Operation > PCM >
Page 358
This is an Open Loop mode. During engine warm-up, the PCM receives inputs from:
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
Based on these inputs the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
- The PCM adjusts engine idle speed through the idle air control (IAC) motor and adjusts ignition
timing.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
- When engine has reached operating temperature, the PCM will begin monitoring 02S sensor
input. The system will then leave the warm-up mode and go into closed loop operation.
IDLE MODE
When the engine is at operating temperature, this is a Closed Loop mode. At idle speed, the PCM
receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Battery voltage
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen sensors Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
injection sequence and injector pulse width by turning the ground circuit to each individual injector
on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio by varying injector pulse width.
It also adjusts engine idle speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by increasing and decreasing spark advance.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
CRUISE MODE
When the engine is at operating temperature, this is a Closed Loop mode. At cruising speed, the
PCM receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen (02S) sensors Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then adjust
the injector pulse width by turning the ground circuit to each individual injector on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio. It also adjusts engine idle
speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.

Page 359
ACCELERATION MODE
This is an Open Loop mode. The PCM recognizes an abrupt increase in throttle position or MAP
pressure as a demand for increased engine output and vehicle acceleration. The PCM increases
injector pulse width in response to increased throttle opening.
DECELERATION MODE
When the engine is at operating temperature, this is an Open Loop mode. During hard
deceleration, the PCM receives the following inputs.
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Vehicle speed
If the vehicle is under hard deceleration with the proper rpm and closed throttle conditions, the
PCM will ignore the oxygen sensor input signal. The PCM will enter a fuel cut-off strategy in which
it will not supply a ground to the injectors. If a hard deceleration does not exist, the PCM will
determine the proper injector pulse width and continue injection.
Based on the above inputs, the PCM will adjust engine idle speed through the idle air control (IAC)
motor. The PCM adjusts ignition timing by turning the ground path to the coil on and off.
WIDE OPEN THROTTLE MODE
This is an Open Loop mode. During wide open throttle operation, the PCM receives the following
inputs.
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal During wide open throttle conditions, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off. The PCM ignores the oxygen sensor input signal and provides a predetermined
amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
IGNITION SWITCH OFF MODE
When ignition switch is turned to OFF position, the PCM stops operating the injectors, ignition coil,
ASD relay and fuel pump relay.

Engine Control Module: Description and Operation Ignition Circuit Sense
This circuit ties the ignition switch to the Powertrain Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage on the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.

Modes of Operation
As input signals to the Powertrain Control Module (PCM) change, the PCM adjusts its response to
the output devices. For example, the PCM must calculate different injector pulse width and ignition
timing for idle than it does for wide open throttle (WOT).
The PCM will operate in two different modes: Open Loop and Closed Loop.
During Open Loop modes, the PCM receives input signals and responds only according to preset
PCM programming. Input from the oxygen (02S) sensors is not monitored during Open Loop
modes.
During Closed Loop modes, the PCM will monitor the oxygen (02S) sensors input. This input
indicates to the PCM whether or not the calculated injector pulse width results in the ideal air-fuel
ratio. This ratio is 14.7 parts air-to-1 part fuel. By monitoring the exhaust oxygen content through
the 02S sensor, the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance.
The fuel injection system has the following modes of operation:
- Ignition switch ON
- Engine start-up (crank)
- Engine warm-up
- Idle
- Cruise
- Acceleration
- Deceleration
- Wide open throttle (WOT)

Page 364
- Ignition switch OFF
The ignition switch On, engine start-up (crank), engine warm-up, acceleration, deceleration and
wide open throttle modes are Open Loop modes. The idle and cruise modes, (with the engine at
operating temperature) are Closed Loop modes.
IGNITION SWITCH (KEY-ON) MODE
This is an Open Loop mode. When the fuel system is activated by the ignition switch, the following
actions occur:
- The PCM pre-positions the idle air control (IAC) motor.
- The PCM determines atmospheric air pressure from the MAP sensor input to determine basic fuel
strategy.
- The PCM monitors the engine coolant temperature sensor input. The PCM modifies fuel strategy
based on this input.
- Intake manifold air temperature sensor input is monitored.
- Throttle position sensor (TPS) is monitored.
- The auto shutdown (ASD) relay is energized by the PCM for approximately three seconds.
- The fuel pump is energized through the fuel pump relay by the PCM. The fuel pump will operate
for approximately three seconds unless the engine is operating or the starter motor is engaged.
- The 02S sensor heater element is energized via the ASD or 02S heater relay. The 02S sensor
input is not used by the PCM to calibrate air-fuel ratio during this mode of operation.
ENGINE START-UP MODE
This is an Open Loop mode. The following actions occur when the starter motor is engaged. The
PCM receives inputs from:
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
The PCM monitors the crankshaft position sensor. If the PCM does not receive a crankshaft
position sensor signal within 3 seconds of cranking the engine, it will shut down the fuel injection
system.
The fuel pump is activated by the PCM through the fuel pump relay.
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
The PCM determines the proper ignition timing according to input received from the crankshaft
position sensor.
ENGINE WARM-UP MODE
This is an Open Loop mode. During engine warm-up, the PCM receives inputs from:
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
Based on these inputs the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
- The PCM adjusts engine idle speed through the idle air control (IAC) motor and adjusts ignition
timing.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
- When engine has reached operating temperature, the PCM will begin monitoring 02S sensor
input. The system will then leave the warm-up mode and go into closed loop operation.
IDLE MODE
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Description and Operation > PCM >
Page 365
When the engine is at operating temperature, this is a Closed Loop mode. At idle speed, the PCM
receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Battery voltage
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen sensors Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
injection sequence and injector pulse width by turning the ground circuit to each individual injector
on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio by varying injector pulse width.
It also adjusts engine idle speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by increasing and decreasing spark advance.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
CRUISE MODE
When the engine is at operating temperature, this is a Closed Loop mode. At cruising speed, the
PCM receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen (02S) sensors Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then adjust
the injector pulse width by turning the ground circuit to each individual injector on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio. It also adjusts engine idle
speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
ACCELERATION MODE
This is an Open Loop mode. The PCM recognizes an abrupt increase in throttle position or MAP
pressure as a demand for increased engine output and vehicle acceleration. The PCM increases
injector pulse width in response to increased throttle opening.
DECELERATION MODE
When the engine is at operating temperature, this is an Open Loop mode. During hard
deceleration, the PCM receives the following inputs.
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Vehicle speed
If the vehicle is under hard deceleration with the proper rpm and closed throttle conditions, the
PCM will ignore the oxygen sensor input signal. The PCM will enter a fuel cut-off strategy in which
it will not supply a ground to the injectors. If a hard deceleration does not exist, the PCM will
determine the proper injector pulse width and continue injection.

Page 366
Based on the above inputs, the PCM will adjust engine idle speed through the idle air control (IAC)
motor. The PCM adjusts ignition timing by turning the ground path to the coil on and off.
WIDE OPEN THROTTLE MODE
This is an Open Loop mode. During wide open throttle operation, the PCM receives the following
inputs.
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal During wide open throttle conditions, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off. The PCM ignores the oxygen sensor input signal and provides a predetermined
amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
IGNITION SWITCH OFF MODE
When ignition switch is turned to OFF position, the PCM stops operating the injectors, ignition coil,
ASD relay and fuel pump relay.
5 Volt Supplies
Two different Powertrain Control Module (PCM) five volt supply circuits are used; primary and
secondary.
Primary 5-volt supply:
- supplies the required 5 volt power source to the Crankshaft Position (CKP) sensor.
- supplies the required 5 volt power source to the Camshaft Position (CMP) sensor.
- supplies a reference voltage for the Manifold Absolute Pressure (MAP) sensor.
- supplies a reference voltage for the Throttle Position Sensor (TPS) sensor.
Secondary 5-volt supply:
- supplies the required 5 volt power source to the oil pressure sensor.
- supplies the required 5 volt power source for the Vehicle Speed Sensor (VSS) (if equipped).
- supplies the 5 volt power source to the transmission pressure sensor (certain automatic
transmissions).
Ignition Circuit Sense
This circuit ties the ignition switch to the Powertrain Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage on the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.
Power Grounds
The Powertrain Control Module (PCM) has 2 main grounds. Both of these grounds are referred to
as power grounds. All of the high-current, noisy, electrical devices are connected to these grounds
as well as all of the sensor returns. The sensor return comes into the sensor return circuit, passes
through noise suppression, and is then connected to the power ground.
The power ground is used to control ground circuits for the following PCM loads:
- Generator field winding
- Fuel injectors
- Ignition coil(s)
- Certain relays/solenoids
- Certain sensors
Sensor Return
The Sensor Return circuits are internal to the Powertrain Control Module (PCM).
Sensor Return provides a low-noise ground reference for all engine control system sensors.

PCM/ECM/SKIM Programming
Engine Control Module: Service and Repair PCM/ECM/SKIM Programming
NOTE: Before replacing the Powertrain Control Module (PCM) or Engine Control Module (ECM),
be certain to check the related component/circuit integrity for failures not detected due to a double
fault in the circuit. Most PCM/ECM driver/control circuit failures are caused by internal component
failures (i.e. relays and solenoids) and shorted circuits (i.e. pull-ups, drivers, and switched circuits).
These failures are difficult to detect when a double fault has occurred and only one DTC has been
set.
When a Powertrain Control Module (PCM) for a gasoline engine, or a Engine Control Module for a
diesel engine and the Sentry Key Immobilizer Module (SKIM) on vehicles equipped with the Sentry
Key Immobilizer System (SKIS) are replaced at the same time, perform the following steps in order:
1. Program the new PCM/ECM. 2. Program the new SKIM. 3. Replace all ignition keys and
program them into the new SKIM.

PCM/ECM/SKIM Programming > Page 369
Engine Control Module: Service and Repair Programming the PCM/ECM/SKIM
The SKIS Secret Key is an ID code that is unique to each SKIM. This code is programmed and
stored in the SKIM, the PCM/ECM, and each ignition key transponder chip. When the PCM/ECM or
SKIM is replaced, it is necessary to program the Secret Key into the new modules using a
diagnostic scan tool. Follow the programming steps outlined in the diagnostic scan tool menu for
the module being replaced as appropriate.
NOTE:
- Be certain to enter the correct country code for the SKIM. If the incorrect country code is
programmed into the SKIM, it cannot be changed and the SKIM must be replaced.
- If the PCM/ECM and the SKIM are replaced at the same time, all vehicle ignition keys will need to
be replaced and the new keys programmed into the new SKIM.
- Programming the PCM/ECM or SKIM is done using a diagnostic scan tool and a PIN to enter
secure access mode. If three attempts are made to enter secure access mode using an incorrect
PIN, secure access mode will be locked out for one hour. To exit this lockout mode, turn the
ignition to the RUN position for one hour then enter the correct PIN. (Ensure all accessories are
turned OFF. Also monitor the battery state and connect a battery charger if necessary).

Engine Control Module: Service and Repair Programming Ignition Keys to the SKIM
Each ignition key transponder also has a unique ID code that is assigned at the time the key is
manufactured. When a key is programmed into the SKIM, the transponder ID code is learned by
the module and the transponder acquires the unique Secret Key ID code from the SKIM. To
program ignition keys into the SKIM, follow the programming steps outlined in the diagnostic scan
tool for "Program Ignition Keys or Key FOBs" under the "SKIM" menu item.
NOTE: A maximum of eight keys can be learned to each SKIM. Once a key is learned to a SKIM,
that key has acquired the Secret Key for that SKIM and cannot be transferred to any other SKIM or
vehicle.
If ignition key programming is unsuccessful, the scan tool will display one of the following error
messages:
- Programming Not Attempted - The scan tool attempts to read the programmed key status and
there are no keys programmed into SKIM memory.
- Programming Key Failed (Possible Used Key From Wrong Vehicle) - SKIM is unable to program
an ignition key transponder due to one of the following: The ignition key transponder is faulty.
- The ignition key transponder is or has been already programmed to another vehicle.
- 8 Keys Already Learned, Programming Not Done - The SKIM transponder ID memory is full.
- Learned Key In Ignition - The ID for the ignition key transponder currently in the ignition lock
cylinder is already programmed into SKIM memory.

Engine Control Module: Service and Repair Module - Powertrain Control
CAUTION:
- Certain ABS systems rely on having the Powertrain Control Module (PCM) broadcast the Vehicle
Identification Number (VIN) over the bus network. To prevent problems of DTCs and other items
related to the VIN broadcast, it is recommend that you disconnect the ABS CAB (controller)
temporarily when replacing the PCM. Once the PCM is replaced, write the VIN to the PCM using
the DRB scan tool. This is done from the engine main menu. Arrow over to the second page to "1.
Miscellaneous". Select "Check VIN" from the choices. Make sure it has the correct VIN entered
before continuing. When the VIN is complete, turn off the ignition key and reconnect the ABS
module connector. This will prevent the setting of DTCs and other items associated with the lack of
a VIN detected when you turn the key ON after replacing the PCM.
- Use the DRB scan tool to reprogram the new PCM with the vehicles original identification number
(VIN) and the vehicles original mileage. If this step is not done, a Diagnostic Trouble Code (DTC)
may be set.
REMOVAL
The PCM (1) is located in the engine compartment attached to the dash panel (3).
To avoid possible voltage spike damage to the PCM, ignition key must be off, and negative battery
cable must be disconnected before unplugging PCM connectors.

Main Relay (Computer/Fuel System): Description and Operation PCM Output
The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power Distribution Center
(PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit on and off.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if:
- the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.

Main Relay (Computer/Fuel System): Description and Operation ASD Sense - PCM Input
A 12 volt signal at this input indicates to the PCM that the ASD has been activated. The relay is
used to connect the oxygen sensor heater element, ignition coil and fuel injectors to 12 volt +
power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Main Relay (Computer/Fuel System): Testing and Inspection
ASD AND FUEL PUMP RELAYS
The following description of operation and tests apply only to the Automatic Shutdown (ASD) and
fuel pump relays. The terminals on the bottom of each relay are numbered. Two different types of
relays may be used, or.
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays,
terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to
terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the
circuit. Terminal 87A is the center terminal on the relay.
- When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30.
This is the On position. Terminal 87 supplies voltage to the rest of the circuit.
The following procedure applies to the ASD and fuel pump relays.
1. Remove relay from connector before testing. 2. With the relay removed from the vehicle, use an
ohmmeter to check the resistance between terminals 85 and 86. The resistance should be 75
ohms
+/- 5 ohms.
3. Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity
between terminals 30 and 87A. 4. Connect the ohmmeter between terminals 87 and 30. The
ohmmeter should not show continuity at this time. 5. Connect one end of a jumper wire (16 gauge
or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12
volt power source.
6. Connect one end of another jumper wire (16 gauge or smaller) to the power side of the 12 volt
power source. Do not attach the other end of the
jumper wire to the relay at this time.
WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS
TEST. DAMAGE TO OHMMETER MAY RESULT.
7. Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The
ohmmeter should now show continuity between relay
terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and
30.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and
Instructions > Page 392
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Instructions > Page 395
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Fuel Pump Relay: Description and Operation
The 5-pin, 12-volt, fuel pump relay is located in the Power Distribution Center (PDC). Refer to the
label on the PDC cover for relay location.
The Powertrain Control Module (PCM) energizes the electric fuel pump through the fuel pump
relay. The fuel pump relay is energized by first applying battery voltage to it when the ignition key is
turned ON, and then applying a ground signal to the relay from the PCM.
Whenever the ignition key is turned ON, the electric fuel pump will operate. But, the PCM will
shut-down the ground circuit to the fuel pump relay in approximately 1 - 3 seconds unless the
engine is operating or the starter motor is engaged.

Main Relay (Computer/Fuel System): Description and Operation PCM Output
The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power Distribution Center
(PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit on and off.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if:
- the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.

Main Relay (Computer/Fuel System): Description and Operation ASD Sense - PCM Input
A 12 volt signal at this input indicates to the PCM that the ASD has been activated. The relay is
used to connect the oxygen sensor heater element, ignition coil and fuel injectors to 12 volt +
power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Main Relay (Computer/Fuel System): Testing and Inspection
ASD AND FUEL PUMP RELAYS
The following description of operation and tests apply only to the Automatic Shutdown (ASD) and
fuel pump relays. The terminals on the bottom of each relay are numbered. Two different types of
relays may be used, or.
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays,
terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to
terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the
circuit. Terminal 87A is the center terminal on the relay.
- When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30.
This is the On position. Terminal 87 supplies voltage to the rest of the circuit.
The following procedure applies to the ASD and fuel pump relays.
1. Remove relay from connector before testing. 2. With the relay removed from the vehicle, use an
ohmmeter to check the resistance between terminals 85 and 86. The resistance should be 75
ohms
+/- 5 ohms.
3. Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity
between terminals 30 and 87A. 4. Connect the ohmmeter between terminals 87 and 30. The
ohmmeter should not show continuity at this time. 5. Connect one end of a jumper wire (16 gauge
or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12
volt power source.
6. Connect one end of another jumper wire (16 gauge or smaller) to the power side of the 12 volt
power source. Do not attach the other end of the
jumper wire to the relay at this time.
WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS
TEST. DAMAGE TO OHMMETER MAY RESULT.
7. Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The
ohmmeter should now show continuity between relay

Ignition Relay: Description and Operation
The ignition system is controlled by the Powertrain Control Module (PCM) on all engines.
The 5.7L V-8 engine is equipped with 16 spark plugs. Two plugs are used for each cylinder. The
5.7L is also equipped with 8 separate and independent ignition coils. The one-piece coil bolts
directly to the cylinder head cover and attaches the coils secondary output terminal directly to a
spark plug using a rubber boot seal. Each coil is also equipped with a second output terminal. This
second terminal connects a conventional spark plug cable directly to a spark plug on the opposite
cylinder bank. A separate primary electrical connector is used for each coil.
Eight conventional spark plug cables are used with the 5.7L. These cables connect a coil on one
cylinder bank, directly to a spark plug on the opposite cylinder bank. The cables are placed and
routed in a special plastic loom to keep them separated. This loom is clipped to the intake manifold.
To prevent a miss-match of cables, a corresponding spark plug/coil number is displayed on each
plug cable: 1/6, 2/3, 4/7 and 5/8. These numbers can also be found on the top of the intake
manifold to the right of the throttle body.
Two knock sensors (one for each cylinder bank) are used to help control spark knock. The 5.7L
engine will not use a conventional distributor.
The ignition system consists of:
- 16 Spark Plugs (2 per cylinder)
- 8 Separate, Dual-Secondary Output, Ignition Coils
- 2 knock Sensors
- 8 Secondary Ignition Cables
- Powertrain Control Module (PCM)
- Also to be considered part of the ignition system are certain inputs from the Crankshaft Position,
Camshaft Position, Throttle Position, 2 knock and MAP Sensors

Air Bag Control Module: Description and Operation
The Airbag Control Module (ACM) (1) is also sometimes referred to as the Occupant Restraint
Controller (ORC). The ACM is located below the instrument panel center stack in the passenger
compartment of the vehicle, where it is secured by three screws to a stamped steel mounting
bracket welded onto the top of the floor panel transmission tunnel just forward of the instrument
panel center support bracket. Concealed within a hollow in the center of the die cast aluminum
ACM housing is the electronic circuitry of the ACM which includes a microprocessor, an electronic
impact sensor, an electronic sating sensor, and an energy storage capacitor. A stamped metal
cover plate is secured to the bottom of the ACM housing with four screws to enclose and protect
the internal electronic circuitry and components.
An arrow (2) printed on the label (3) on the top of the ACM housing provides a visual verification of
the proper orientation of the unit, and should always be pointed toward the front of the vehicle. The
ACM housing has integral mounting flanges on three corners. The mounting flange to the left of the
connector receptacle has an integral locating pin on its lower surface. Both left side flanges have
round mounting holes, while the flange on the right side has a slotted mounting hole. A molded
plastic electrical connector (4) with two receptacles, one containing twenty-four terminal pins and
the other containing thirty-two terminal pins, exits the rearward facing side of the ACM housing.
These terminal pins connect the ACM to the vehicle electrical system through two dedicated take
outs and connectors of the instrument panel wire harness.
The impact sensor and sating sensor internal to the ACM are calibrated for the specific vehicle, and
are only serviced as a unit with the ACM. In addition, there are unique versions of the ACM for light
and heavy-duty models, and for vehicles with or without the optional side curtain airbags. The ACM
cannot be repaired or adjusted and, if damaged or faulty, it must be replaced.
The microprocessor in the Airbag Control Module (ACM) contains the supplemental restraint
system logic circuits and controls all of the supplemental restraint system components. The ACM
uses On-Board Diagnostics (OBD) and can communicate with other electronic modules in the
vehicle as well as with the diagnostic scan tool using the Programmable Communications Interface
(PCI) data bus network. This method of communication is used for control of the airbag indicator in
the ElectroMechanical Instrument Cluster (EMIC) and for supplemental restraint system diagnosis
and testing through the 16-way data link connector located on the driver side lower edge of the
instrument panel.
The ACM microprocessor continuously monitors all of the supplemental restraint system electrical
circuits to determine the system readiness. If the ACM detects a monitored system fault, it sets an
active and stored Diagnostic Trouble Code (DTC) and sends electronic messages to the EMIC
over the PCI data bus to turn on the airbag indicator. An active fault only remains for the duration of
the fault, or in some cases for the duration of the current ignition switch cycle, while a stored fault
causes a DTC to be stored in memory by the ACM. For some DTCs, if a fault does not recur for a
number of ignition cycles, the ACM will automatically erase the stored DTC. For other internal
faults, the stored DTC is latched forever.
In standard cab models, the ACM also monitors a resistor multiplexed input from the passenger
airbag on/off switch and provides a control output for the Off indicator in the switch through a
passenger airbag indicator driver circuit. If the passenger airbag on/off switch is set to the Off
position, the ACM turns on the passenger airbag on/off switch Off indicator and will internally
disable the passenger airbag from being deployed. The ACM also turns on the on/off switch Off
indicator for about seven seconds each time the ignition switch is turned to the On position as a
bulb test. Following the bulb test, the ACM controls the status of the Off indicator based upon the
resistance of the input from the on/off switch. The ACM will also set and/or store a DTC for faults it
detects in the passenger airbag on/off switch circuits, and will turn on the airbag indicator in the
EMIC if a fault has been detected.
The ACM receives battery current through two circuits; a fused ignition switch output (run) circuit
through a fuse in the Integrated Power Module (IPM), and a fused ignition switch output (run-start)
circuit through a second fuse in the IPM. The ACM receives ground through a ground circuit and
take out of the instrument panel wire harness. This take out has a single eyelet terminal connector
that is secured by a ground screw to the instrument panel structural support. These connections
allow the ACM to be operational whenever the ignition switch is in the Start or On positions.
The ACM also contains an energy-storage capacitor. When the ignition switch is in the Start or On
positions, this capacitor is continually being charged with enough electrical energy to deploy the
supplemental restraint components for up to one second following a battery disconnect or failure.
The purpose of the capacitor is to provide backup supplemental restraint system protection in case
there is a loss of battery current supply to the ACM during an impact.

Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Restraint Systems > Air Bag Control Module >
Component Information > Locations > Page 440
Two sensors are contained within the ACM, an electronic impact sensor and a safing sensor. The
electronic impact sensors are accelerometers that sense the rate of vehicle deceleration, which
provide verification of the direction and severity of an impact. On models equipped with optional
side curtain airbags, the ACM also monitors inputs from two remote side impact sensors located
within both the left and right B-pillars to control deployment of the side curtain airbag units.
The safing sensor is an electronic accelerometer sensor within the ACM that provides an additional
logic input to the ACM microprocessor. The safing sensor is used to verify the need for a
supplemental restraint deployment by detecting impact energy of a lesser magnitude than that of
the primary electronic impact sensors, and must exceed a safing threshold in order for the airbags
to deploy. Vehicles equipped with optional side curtain airbags feature a second safing sensor
within the ACM to provide confirmation to the ACM microprocessor of side impact forces. This
second safing sensor is a bi-directional unit that detects impact forces from either side of the
vehicle.
Pre-programmed decision algorithms in the ACM microprocessor determine when the deceleration
rate as signaled by the impact sensors and the safing sensors indicate an impact that is severe
enough to require supplemental restraint system protection and, based upon the severity of the
monitored impact and the status of the passenger airbag on/off switch input, determines the level of
front airbag deployment force required for each front seating position. When the programmed
conditions are met, the ACM sends the proper electrical signals to deploy the dual multistage front
airbags at the programmed force levels, the front seat belt tensioners and, if the vehicle is so
equipped, either side curtain airbag unit. For vehicles equipped with the passenger airbag on/off
switch, the passenger front airbag and seat belt tensioner will be deployed by the ACM only if
enabled by the switch (passenger airbag on/off switch indicator Off) at the time of the impact.
The hard wired inputs and outputs for the ACM may be diagnosed and tested using conventional
diagnostic tools and methods. However, conventional diagnostic methods will not prove conclusive
in the diagnosis of the ACM, the PCI data bus network, or the electronic message inputs to and
outputs from the ACM. The most reliable, efficient, and accurate means to diagnose the ACM, the
PCI data bus, and the electronic message inputs to and outputs from the ACM requires the use of
a diagnostic scan tool.

Starter Relay: Description and Operation
The starter relay is an electromechanical device that switches battery current to the pull-in coil of
the starter solenoid when ignition switch is turned to Start position. The starter relay is located in
the Power Distribution Center (PDC) in the engine compartment. See PDC cover for relay
identification and location.
The starter relay is a International Standards Organization (ISO) relay. Relays conforming to ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions.
The starter relay cannot be repaired or adjusted. If faulty or damaged, it must be replaced.
The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one
movable) electrical contacts. The movable (common feed) relay contact is held against one of the
fixed contacts (normally closed) by spring pressure. When electromagnetic coil is energized, it
draws the movable contact away from normally closed fixed contact, and holds it against the other
(normally open) fixed contact.
When electromagnetic coil is de-energized, spring pressure returns movable contact to normally
closed position. The resistor or diode is connected in parallel with electromagnetic coil within relay,
and helps to dissipate voltage spikes produced when coil is de-energized.

Starter Relay: Testing and Inspection
The starter relay is located in Power Distribution Center (PDC). Refer to PDC cover for relay
identification and location. For complete starter relay wiring circuit diagrams, refer to Wiring
Diagrams.
1. Remove starter relay from PDC 2. A relay in de-energized position should have continuity
between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go
to Step 3. If not OK, replace faulty relay.
3. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to
Step 4. If not OK, replace faulty relay. 4. Connect 12 V battery to terminals 85 an 86. There should
now be continuity between terminals 30 and 87, and no continuity between terminals
87A and 30. If OK, perform Relay Circuit Test that follows. If not OK, replace faulty relay.
RELAY CIRCUIT TEST
1. The relay common feed terminal cavity (30) is connected to battery voltage and should be hot at
all times. If OK, go to Step 2. If not OK, repair
open circuit to fuse in PDC as required.
2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized
position, but is not used for this application. Go to Step
3.
3. The relay normally open terminal (87) is connected to common feed terminal (30) in the
energized position. This terminal supplies battery voltage
to starter solenoid field coils. There should be continuity between cavity for relay terminal 87 and
starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair open circuit to starter
solenoid as required.
4. The coil battery terminal (86) is connected to electromagnet in relay. It is energized when ignition
switch is held in Start position. On vehicles with
manual transmission, clutch pedal must be fully depressed for this test. Check for battery voltage at
cavity for relay terminal 86 with ignition switch in Start position, and no voltage when ignition switch
is released to On position. If OK, go to Step 5. If not OK with automatic transmission, check for
open or short circuit to ignition switch and repair, if required. If circuit to ignition switch is OK, refer
to Ignition Switch and Key Lock Cylinder. If not OK with a manual transmission, check circuit
between relay and clutch pedal position switch for open or a short. If circuit is OK, refer to Clutch
Pedal Position Switch.
5. The coil ground terminal (85) is connected to the electromagnet in the relay. On vehicles with
manual transmission, it is grounded at all times. On
vehicles with automatic transmission, it is grounded through park/neutral position switch only when
gearshift selector lever is in Park or Neutral positions. Check for continuity to ground at cavity for
relay terminal 85. If not OK with manual transmission, repair circuit to ground as required. If not OK
with automatic transmission, check for pen or short circuit to park/neutral position switch and repair,
if required. If circuit to park/neutral position switch is OK, refer to Park/Neutral Position Switch,
Transmission.

Control Module: Description and Operation
The Transmission Control Module (TCM) (2) may be sub-module within the Powertrain Control
Module (PCM) (3).
Or, for vehicles with a diesel engine, the Engine Control Module (ECM) (1). The PCM, and TCM
when equipped, is located at the right rear of the engine compartment, near the right inner fender.
The Transmission Control Module (TCM) controls all electronic operations of the transmission. The
TCM receives information regarding vehicle operation from both direct and indirect inputs, and
selects the operational mode of the transmission. Direct inputs are hard wired to, and used
specifically by the TCM. Indirect inputs are shared with the TCM via the vehicle communication
bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Transmission and Drivetrain > Relays and
Modules - A/T > Control Module, A/T > Component Information > Description and Operation > Page 459
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request Some examples of TCM indirect outputs are:
- Transmission Temperature (to PCM)
- PRNDL Position (to cluster/CCN) In addition to monitoring inputs and controlling outputs, the TCM
has other important responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed.
BATTERY FEED
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain memory in the TCM. When the battery (B+) is disconnected, this memory is
lost. When the battery (B+) is restored, this memory loss is detected by the TCM and a Diagnostic
Trouble Code (DTC) is set.
CLUTCH VOLUME INDEXES (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur.
Gear ratios can be determined by using the Scan Tool and reading the Input/Output Speed Sensor
values in the "Monitors" display Gear ratio can be obtained by dividing the Input Speed Sensor
value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Transmission and Drivetrain > Relays and
Modules - A/T > Control Module, A/T > Component Information > Description and Operation > Page 460
In direct drive (3rd gear), the gear ratio changes to 1:1. The gear ratio changes as clutches are
applied and released. By monitoring the length of time it takes for the gear ratio to change following
a shift request, the TCM can determine the volume of fluid used to apply or release a friction
element.
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Certain mechanical problems within the input clutch assembly can cause inadequate or
out-of-range element volumes. Also, defective Input/Output Speed Sensors and wiring can cause
these conditions. The following chart identifies the appropriate clutch volumes and when they are
monitored/updated:
SHIFT SCHEDULES
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following:
- Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Transmission and Drivetrain > Relays and
Modules - A/T > Transmission Control System Relay, A/T > Component Information > Diagrams > Diagram Information and
Instructions > Page 467
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagrams may appear to be

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Modules - A/T > Transmission Control System Relay, A/T > Component Information > Diagrams > Diagram Information and
Instructions > Page 470
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Transmission Control System Relay: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Fig.7 Testing For Voltage Potential
STANDARD PROCEDURE - TESTING OF VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

2. Connect the other lead of the voltmeter to the other side of the switch, component or circuit. 3.
Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Transmission and Drivetrain > Relays and
Modules - A/T > Transmission Control System Relay, A/T > Component Information > Diagrams > Diagram Information and
Instructions > Page 486
- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Transmission Control System Relay: Description and Operation Relay-Transmission Control
RELAY-TRANSMISSION CONTROL 45RFE/545RFE
DESCRIPTION
NOTE: The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power
to the solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off", no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Control Module: Description and Operation
The Transfer Case Control Module (TCCM) (2) is a microprocessor-based assembly, controlling
the 4X4 transfer case shift functions via the actuation of a shift motor and utilizing the feedback of a
mode sensor assembly. Communication is via the PCI serial bus. Inputs include user selectable
4X4 modes that include 2WD, AWD, 4HI, 4LO, and Neutral. The logic and driver circuitry is
contained in a molded plastic housing with an embedded heat-sink and is located behind the left
side of the lower instrument panel (1).
The Transfer Case Control Module (TCCM) utilizes the input from the transfer case mounted mode
sensor, the instrument panel mounted selector switch, and the following information from the
vehicle's PCI serial bus to determine if a shift is allowed.
- Engine RPM and Vehicle Speed
- Diagnostic Requests
- Manual Transmission and Brake Applied
- PRNDL
- Ignition Status
- ABS Messages
Once the TCCM determines that a requested shift is allowed, it actuates the bi-directional shift
motor as necessary to achieve the desired transfer case operating mode. The TCCM also monitors
the mode sensor while controlling the shift motor to determine the status of the shift attempt.
Several items can cause the requested shift not to be completed. If the TCCM has recognized a
fault (DTC) of some variety, it will begin operation in one of four Functionality Levels. These levels
are:
- Level Zero - Normal Operation.
- Level One - Only Mode Shifts Are Allowed.
- Level Two - Only Mode Shifts and Shifts Into LOW Are Allowed (No Neutral Shifts Are Allowed).
- Level Three - No Shifts Are Allowed
The TCCM can also be operating in one of three possible power modes. These power modes are:
- Full Power Mode is the normal operational mode of the module. This mode is achieved by normal
PCI bus traffic being present and the ignition being in the RUN position.
- Reduced Power Mode will be entered when the ignition has been powered off. In this state, the
module will shut down power supplied to external devices, and to electronic interface inputs and
outputs. From this state the module can enter either Sleep Mode or Full Power Mode. To enter this
mode, the module must receive an ignition message denoting that the ignition is off, or not receive
any messages for 5 ± 0.5 seconds. To exit this mode, the module must receive one ignition
message that denotes that the ignition is in the RUN position.
- Sleep Mode will be entered, from the Reduced Power Mode, when no PCI traffic has been
sensed for 20 ± 1 seconds. If during Sleep Mode the module detects PCI bus traffic, it will revert to
the Reduced Power mode while monitoring for ignition messages. It will remain in this state as long
as there is traffic other than run or start messages, and will return to Sleep mode if the bus goes
without traffic for 20 ± 1 seconds.
SHIFT REQUIREMENTS
If the TCCM is in full power mode and at functionality level zero, it uses the following criteria to
determine if a shift is allowed.
If any of the driver controllable conditions are not met once the shift request is recognized, the
TCCM will solidly illuminate the source position's LED and flash the desired position's LED for all
shifts except NEUTRAL. The NEUTRAL shift LED strategy will be discussed later.
Mode shifts will be allowed regardless of transmission gear or vehicle speed, whenever the
following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- A change in the Selector switch state indicates that a mode shift has been requested.
- A valid mode sensor signal is being sensed by the TCCM.

- Ignition key switch is in the RUN position.
- Foot Brake is applied.
- A valid mode sensor signal is being sensed by the TCCM.
SHIFT SEQUENCES
Once all the driver controllable conditions for the requested shift have been met, the TCCM begins
a shift timer with a maximum duration of 1 second per 'D' channel transition. If the shift timer
expires before the TCCM recognizes to correct mode sensor code, the shift is considered to have
been blocked. The blocked shift will increment the blocked shift counter by one. The TCCM
strategy for handling blocked shifts will be described later. The process the TCCM performs for the
various shifts will be described first.
RANGE AND MODE SHIFTS
The process for performing all the range and mode shifts are the same. The following steps
describe the process.
- Allow time for Selector Switch debounce; 250 msec ± 50 msec.
- Extinguish the source gear's LED while flashing desired transfer case position's LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec per 'D' channel transition in the
destination gear's direction while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Solidly illuminate the selected gear's LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 seconds ± 100 msec. per 'D'
channel. The TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the
desired position.
The exception to the preceding sequence is when a shift from 4L to 2WD/AWD is requested. If
2WD/AWD is requested from the 4L position, the transfer case is first driven to the 4H position. If
the 4H position is reached, the transfer case is then driven back to the 2WD/AWD position and the
shift is considered complete. If the transfer case does not reach any the 4H position, but is in the
2WD/AWD 'D' channel, or the 2WD/AWD between gear position on the 4H side of 2WD/AWD, the
shift is also considered complete.
SHIFT OUT OF NEUTRAL
The following steps describe the process for a shift out of NEUTRAL.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Transmission and Drivetrain > Relays and
Modules - Transfer Case > Control Module, Transfer Case > Component Information > Locations > Page 500
- Extinguish the Neutral LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec toward the transfer case 4H mode
position while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Extinguish the Neutral LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 ± seconds 100 msec. The
TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the desired position.
- When the Neutral button is released, if the 4H position is the desired position, the shift is
complete. Illuminate the 4H LED.
- Otherwise when the Neutral button is released, if all of the shift requirements are being met then
engage the shift motor towards the desired position for 1 second ± 100 msec per 'D' channel, (if
requirements for shifting are not met, illuminate the 4H LED and flash the destination LED as an
indication to the driver that all of the driver controllable shift conditions are not being met). If this
requires another range or mode shift, begin the range/mode shift process.
- If the desired mode sensor code is not received after the shift timer expires (i.e. a blocked or other
condition exists), refer to the Blocked Shift Strategy.
BLOCKED SHIFT STRATEGY
When a shift is commanded, the shift motor will be driven towards its destination position, except in
the case of shifting out of Neutral if 4L was selected (the transfer case will shift to the 4H position
first, before proceeding to 4L). If the shift is blocked on the way to the destination, the TCCM may
attempt to drive the motor back to the original position. This process will be allowed to occur 5
times. If the transfer case has reached a non-NEUTRAL 'D' channel during the shift re-attempts,
the LED for the achieved gear position is illuminated and the shift attempts are stopped. To
re-attempt the desired shift, the selector switch will need to be rotated to the current position until
the switch debounce timer expires then a shift will need to be requested again.
At the end of the 5th blocked attempt, the shift motor is driven towards the last known 'D' channel
position. If this motor drive allows the transfer case to reach the 2WD/AWD 'D' channel, or the
2WD/AWD between gear position on the 4H side of 2WD/AWD, the shift is considered complete
and the shift attempts are ended.
If the mode sensor is in the NEUTRAL region at the expiration of the shift timer, the TCCM will
continue to make the shift attempts according to the blocked shift strategy independent of whether
or not the driver controlled conditions are met.
For shifts from NEUTRAL, if all 5 attempts fail to reach the desired position (which by default is
4H), the motor will be driven to stall in the direction of 4H or 4L, depending on the achieved
position. If the transfer case has reached the 2WD/AWD or 4L between gear position nearest the
NEUTRAL positions and the shift conditions are no longer being met, the transfer case will be
driven toward the corresponding 'D' channel. Otherwise, the transfer case will be driven in the
direction opposite the last attempt with the desired target being 4H or 4L.
If the transfer case reaches the 2WD/AWD 'D' channel when being driven in the 4H direction, then
one final 1.0 second drive toward 4H is attempted. If the transfer case then reaches any of the 4H
positions, the shift is considered complete and the 4H LED is illuminated. If the transfer case is still
the 2WD/AWD position, the shift is considered complete and the 2WD/AWD LED is illuminated.
NOTE: If after the 5th blocked shift and reversal attempt, if the transfer case position is in the
NEUTRAL region, shift attempts will continue until a non-NEUTRAL 'D' channel is reached.
SHIFT REVERSAL TARGETS
If the shift timer expires (1 second per 'D' channel) and the transfer case has not reached the
desired position, all shifts will attempt to return to their original position with the exceptions of:
- If the intended shift is going to the High rail from Low and can't make it, but it can make the
2WD/AWD position, the motor stops at that position. The TCCM will not attempt to cross back over
NEUTRAL if it does not have to. This means that there was a block on the first attempt to go to 4H
and the transfer case has made it through NEUTRAL to a known good position, then the motor will
go back only to the 2WD/4WD position and execute the remainder of the attempts from there.
- For shifts out of NEUTRAL, any time a shift is commanded out of NEUTRAL, the system needs to
get out. The TCCM should never go to NEUTRAL unless the driver is commanding it and all
required conditions are being met
ENCODER DRIFT CORRECTION
Whenever a shift is completed, the TCCM stores the position in memory as the transfer case's
intended position. The TCCM continuously monitors the mode sensor and if the mode sensor drifts
toward into a NEUTRAL region sensor position for 2.0 seconds, the TCCM will perform a motor
drive to correct the drift. The transfer case will be driven toward the intended position for 1.0
seconds 100 msec. The TCCM will wait for 2.0 seconds ± 50 msec . and repeat the attempt to shift
to the desired position. This will continue until the intended position is reached.
SHIFT MOTOR BRAKING
Two modes of shift motor braking are employed to improve shift performance, static and dynamic.
Static shift motor braking is utilized under the
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Transmission and Drivetrain > Relays and
Modules - Transfer Case > Control Module, Transfer Case > Component Information > Locations > Page 501
following conditions:
- Whenever the transfer case is in the 2WD/AWD or 4L 'D' channel position.
- Whenever an invalid mode sensor code is present. Static motor braking is achieved by applying
+12V on both shift motor wires. NOTE: Static Shift Motor Braking is independent of ignition key
position.
SHIFT ATTEMPT LIMIT
To protect the transfer case system, the TCCM will impose a limit on the number of shifts that can
occur over a calibrated time period. The system will monitor the number of 'D' channel segment
transitions that occur in any 30 second time period. If the number of segment transitions is 30 or
greater, the system will go into a default mode. The default mode of operation for shifting is that the
number of allowed 'D' channel transitions permitted to occur will be 3 over each 15 second ± 100
msec calibrated window of time. After 5 minutes ± 100 msec, the motor can be assumed to have
cooled down and the system will revert to normal operation. The following rules also apply to the
shift limit:
- The attempt limit will not prevent shifts coming out of NEUTRAL, they will be allowed regardless
of the counter/timer.
- Any shift that is in progress when the counter reaches a maximum count in time will be allowed to
complete before the default mode is entered. D-channel transitions during this period will not be
counted towards the default mode limit.
- A block, regardless of the direction, whether towards destination or back towards reversal target
(shift timer expiring), will count as a value of 2 transitions towards the 30 segment transitions to go
into default mode as defined above. Current attempt limit values are 30 transitions in 30 seconds
and default mode values are 3 transitions every 15 seconds for 5 minutes.

must be replaced.
The rear window defogger relay is an electromechanical switch that uses a low current input from
the integrated power module (IPM) to control the high current output to the rear window defogger
grid The movable common feed contact point is held against the fixed normally closed contact point
by spring pressure When the relay coil is energized, an electromagnetic field is produced by the
coil windings This electromagnetic field draws the movable relay contact point away from the fixed
normally closed contact point, and holds it against the fixed normally open contact point When the
relay coil is de-energized, spring pressure returns the movable contact point back against the fixed
normally closed contact point The resistor or diode is connected in parallel with the relay coil in the
relay, and helps to dissipate voltage spikes and electromagnetic interference that can be generated
as the electromagnetic field of the relay coil collapses.
The rear window defogger relay terminals are connected to the vehicle electrical system through a
receptacle in the IPM The inputs and outputs of the rear window defogger relay include:
- The common feed terminal (30) receives a battery current input from fuse 27 (15 amp) in the IPM
through a fused B(+) circuit at all times

Rear Defogger Relay: Description and Operation
The rear window defogger (EBL) relay (1) is a International Standards Organization (ISO)-type
relay. Relays conforming to the ISO specifications have common physical dimensions, current
capacities, terminal functions and patterns (2). The EBL relay is a electromechanical device that
switches battery current through a fuse in the integrated power module (IPM) to the rear window
defogger grid. The EBL relay is energized when the relay coil is provided a ground path by the
control circuitry within the A/C-heater control.
The EBL relay is located in the IPM in the engine compartment.
The ISO-standard rear window defogger (EBL) relay is an electromechanical switch that uses a low
current input controlled by the A/C-heater control to control the high current output to the rear
window defogger grid lines. The movable, common feed relay contact is held against the fixed,
normally closed relay contact by spring pressure. When the electromagnetic relay coil is energized,
it draws the movable common feed relay contact away from the fixed, normally closed relay contact
and, holds it against the fixed, normally open relay contact. This action allows high current to flow
to the rear window defogger grid lines.
When the relay coil is de-energized, spring pressure returns the movable relay contact back
against the fixed, normally closed contact point. The resistor or diode is connected in parallel with
the relay coil, and helps to dissipate voltage spikes and electromagnetic interference that can be
generated as the electromagnetic field of the relay coil collapses.
The EBL relay terminals are connected to the vehicle electrical system through a receptacle in the
integrated power module (IPM). The inputs and outputs of the EBL relay include:
- Terminal (30) receives battery current through a fuse in the IPM only when the EBL relay coil is
energized.
- Terminal (85) receives a ground through the EBL relay control circuit only when the A/C-heater
control electronically pulls the circuit to ground.
- Terminal (86) receives battery current through a fused ignition switch output circuit only when the
ignition switch is in the Run position.
- Terminal (87) provides battery current to the rear window defogger grid lines through the EBL
relay only when the EBL relay coil is energized.
- Terminal (87A) is not connected to any circuit in this application.
The EBL relay cannot be repaired and, if faulty or damaged, it must be replaced. Refer to the
appropriate wiring information for diagnosis and testing of the ISO-standard relay and for complete
rear window defogger (EBL) wiring diagrams.

Wiper Relay: Description and Operation Wiper High/Low Relay
The wiper high/low relay is a conventional International Standards Organization (ISO) micro relay.
Relays conforming to the ISO specifications have common physical dimensions, current capacities,
terminal patterns, and terminal functions. This relay is contained within a small, rectangular,
molded plastic housing and is connected to all of the required inputs and outputs through five

switch is in the On or Accessory positions from a fuse in the PDC/IPM through a fused ignition
switch output (run-acc) circuit.
- Normally Open Terminal - The normally open terminal (87) is connected to the high speed brush
of the wiper motor through a wiper high/low relay high speed output circuit, and is connected to the
high speed brush whenever the relay is energized.
- Normally Closed Terminal - The normally closed terminal (87A) is connected to the low speed
brush of the wiper motor through a wiper high/low relay low speed output circuit, and is connected
to the low speed brush whenever the relay is de-energized.
The wiper high/low relay can be diagnosed using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the
ElectroMechanical Instrument Cluster (EMIC), the FCM, or the electronic message inputs to or
outputs from the EMIC and the FCM that control the operation of the wiper high/low relay. The
most reliable, efficient, and accurate means to diagnose the wiper high/low relay, the EMIC, the

Remote Switch: Description and Operation
Two rocker-type switches (if equipped) are mounted on the back (instrument panel side) of the
steering wheel spokes. The switch on the left spoke is the seek switch and has seek up, seek
down, and preset station advance functions. The switch on the right spoke is the volume control
switch and has volume up, and volume down functions. The switch on the right spoke also includes
a "mode" control that allows the driver to sequentially select AM radio, FM radio, cassette player,
CD player or CD changer (if equipped).
The six switches in the two remote radio switch units are normally open, resistor multiplexed
momentary switches that are hard wired to the Integrated Power Module (IPM) through the
clockspring. The IPM sends a five volt reference signal to both switch units on one circuit, and
senses the status of all of the switches by reading the voltage drop on a second circuit.
When the IPM senses an input (voltage drop) from any one of the remote radio switches, it sends
the proper switch status messages on the Programmable Communication Interface (PCI) data bus
network to the radio receiver. The electronic circuitry within the radio receiver is programmed to
respond to these remote radio switch status messages by adjusting the radio settings as
requested. For diagnosis of the IPM or the PCI data bus, the use of a scan tool and the proper
Diagnostic Procedures information is recommended.

Door Position Switch: Description and Operation
Vehicles that are equipped with the optional Vehicle Theft Security System (VTSS) have a door
cylinder lock switch (1) secured to the back of the key lock cylinder inside the driver side front door.
The door cylinder lock switch is a resistor multiplexed momentary switch that is hard wired in series
between ground and the cylinder lock switch mux circuit input to the ElectroMechanical Instrument
Cluster (EMIC) through a pigtail wire (2) connected to the left front door wire harness. The door
cylinder lock switch is driven by the key lock cylinder and contains two internal resistors. One
resistor value is used for the Lock position, and one for the Unlock position.
The door cylinder lock switch cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.
The door cylinder lock switch is actuated by the key lock cylinder when the key is inserted in the
lock cylinder and turned to the lock or unlock positions. The door cylinder lock switch closes a
circuit between ground and the cylinder lock switch mux circuit through one of two internal resistors
for the ElectroMechanical Instrument Cluster (EMIC) when the driver side front door key lock
cylinder is in the Lock, or Unlock positions. The EMIC reads the switch status through an internal
pull-up, then uses this information as an input for the Vehicle Theft Security System (VTSS)
operation, as well as for control of a central locking feature for the power lock system.
The door cylinder lock switch and circuit may be diagnosed using conventional diagnostic tools and
methods. However, conventional diagnostic methods may not prove conclusive in the diagnosis of
the EMIC or its responses to the cylinder lock switch inputs. The most reliable, efficient, and
accurate means to diagnose the door cylinder lock switch, the EMIC, and both the hard wired and
electronic message inputs and outputs affected by the door cylinder lock switch inputs requires the
use of a diagnostic scan tool.

Power Door Lock Switch: Description and Operation
A window/lock switch is used on all models equipped with power locks, power windows, and power
mirrors. The window/lock switch houses the following switches:
- Power Lock Switch - A two-way, momentary, resistor multiplexed switch to control the power lock
system.
- Power Mirror Selector Switch - A three-position rocker switch selects the right or left power mirror
for adjustment, or turns the power mirror system Off.
Power Mirror Adjustment Switches - Four momentary, arrowhead shaped, directional switches
allow the driver to adjust the selected power mirror in the Up, Down, Right, or Left directions.
- Power Window Lockout Switch - A two-way, latching, push-button switch allows the vehicle
operator to lock out the power window switches on each passenger door so that the passenger
door power windows may be operated only from the master switches.
- Power Window Switches - A two-way, momentary power window switch for the driver side front
door. This switch also has a second detent in the Down direction and internal circuitry to provide an
Auto-Down feature for the driver side front door power window. In addition to the power window
switch for its own door, there are individual master switches for each passenger door power
window.
The window/lock switch also incorporates several green Light-Emitting Diodes (LEDs) that
illuminate the power lock and power window switch paddles, and the power mirror switch
directional buttons to improve switch visibility.
The window/lock switch combines a power lock switch, a driver power window switch with an
Auto-down feature, master switches for each passenger door power window, a power window
lockout switch, a power mirror selector switch, and four power mirror adjustment switches in a
single unit.
Power Lock Switch
The power lock switch circuitry is connected in series between ground and the driver door switch
mux input of the instrument cluster. Each power lock switch position (Lock, Unlock, and Neutral)
provides a different resistance value to the instrument cluster input, which allows the instrument
cluster to sense the switch position. Based upon the power lock switch input, the instrument cluster
controls the battery and ground feed outputs to the individual power lock motors to lock or unlock
the door latches. The Light-Emitting Diode (LED) in the power lock switch is connected to battery
current through the power window circuit breaker in the Integrated Power Module (IPM) on a fused
ignition switch output (run-acc) circuit. The switch will be illuminated whenever the ignition switch is
in the On or Accessory positions.
Power Window Switches
The power window switch circuitry is connected to battery current through a circuit breaker in the
Integrated Power Module (IPM) on a fused ignition switch output (run-acc) circuit so that the power
windows will operate whenever the ignition switch is in the On or Accessory positions. Each
two-way, momentary master passenger power window switch provides battery current and ground
to the individual power window switches on each passenger door so that the power window switch
controls the battery current and ground feeds to its respective power window motor. The switch for
the driver side front door power window is labeled "Auto" and includes an auto-down feature. When
this switch is depressed to a second momentary detent position and released, the driver door
power window is automatically operated through an internal circuit and relay to its fully lowered
position. The Auto-down event is cancelled if the switch paddle is depressed a second time in
either the Up or Down direction. When the two position window lockout switch is depressed and
latched in the lockout position, the battery current feed to each of the individual passenger power
window switches is interrupted so that the passenger door power windows can only be operated
from the master switches. The window lockout switch also controls the battery current feed for the
LED in each passenger power window switch so that the switch will not be illuminated when it is
locked out.
Power Mirror Switches
The power mirror switch circuitry is connected to battery current through a fuse in the IPM on a
fused B(+) circuit so that the power mirrors remain operational regardless of the ignition switch
position. A rocker type selector switch has three positions, one to select the right mirror, one to
select the left mirror, and a neutral Off position. After the right or left mirror is selected, one of four
directional buttons is depressed to move the selected mirror Up, Down, Right or Left. The power
mirror switch circuitry controls the battery current and ground feeds to each of the four (two in each
mirror head) power mirror motors. The Light-Emitting Diode (LED) in the power mirror switch is
connected to battery current through the power window circuit breaker in the IPM on a fused
ignition switch output (run-acc) circuit so that the switch directional buttons will be illuminated
whenever the ignition switch is in the On or Accessory positions.

Power Seat Switch: Description and Operation
The power seats on this vehicle can be adjusted in eight different directions, up, down, front up,
front down, rear up, rear down, rearward and forward. The power seat switch is located on the
outboard side of the seat cushion on the seat cushion side shield.
The individual switches in the power seat switch assembly cannot be repaired. If one switch is
damaged or inoperative, the entire power seat switch assembly must be replaced.
When a power switch control knob or knobs are actuated, a battery feed and a ground path are
applied through the switch contacts to the power seat track adjuster motor. The selected adjuster
motor operates to move the seat track or recliner through its drive unit in the selected direction until
the switch is released, or until the travel limit of the adjuster is reached. When the switch is moved
in the opposite direction, the battery feed and ground path to the motor are reversed through the
switch contacts. This causes the adjuster motor to run in the opposite direction.
No power seat switch should be held applied in any direction after the adjuster has reached its
travel limit. The power seat adjuster motors each contain a self-resetting circuit breaker to protect
them from overload. However, consecutive or frequent resetting of the circuit breaker must not be
allowed to continue, or the motor may be damaged.

Seat Heater Sensor: Description and Operation
The heated seat temperature sensor is a Negative Temperature Coefficient (NTC) thermistor. One
temperature sensor is used for each seat. This temperature sensor is located in the seat cushion
heating element on all models.
The heated seat temperature sensor cannot be repaired or adjusted and must be replaced if
inoperative. The heated seat temperature sensor is part of the heated seat cushion element and
must be replaced as an assembly.
When the temperature of the seat cushion cover rises, the resistance of the sensor decreases. The
heated seat module supplies five-volts to one side of each sensor, and monitors the voltage drop
through the sensor on a return circuit. The heated seat module uses this temperature sensor input
to monitor the temperature of the seat, and regulates the current flow to the seat heating elements
accordingly.

Seat Heater Switch: Description and Operation
The momentary, bidirectional rocker-type heated seat switch (1) provides a resistor-multiplexed
signal to the heated seat module via a mux circuit. Each switch has a center neutral position and
momentary Low and High positions so that both the driver and the front seat passenger can select
a preferred level of seat heating. Each heated seat switch has two Light-Emitting Diode (LED)
indicator lamps (2), which indicate the selected mode (Low or High) of the seat heater. These
indicator lamps also provide diagnostic feedback for the heated seat system. Each switch also has
an incandescent bulb, which provides dimmer controlled back lighting of the switch when the
headlamps or park lamps are on.
The heated seat switches are both mounted in the instrument panel center bezel, located in the
lower center of the instrument panel. The two switches are snapped into the mounting holes of the
heated seat switch bezel, and the heated seat switch bezel is secured with screws to the
instrument panel center bezel. The heated seat switches are differentiated by the keyway in the
connector receptacle on the backs of the switches and keyway on the switch housing. The
instrument panel wire harness connectors for the heated seat switches are keyed to match the
connector receptacles on the switches so that the two heated seat switches can only be connected
to the proper heated seat electrical.
The two LED indicator lamps and the incandescent bulb in each heated seat switch cannot be
repaired. If the indicator lamps or back lighting bulb are faulty or damaged, the individual heated
seat switch must be replaced.
The heated seat switches receive battery current through a fused ignition switch output (run) circuit
when the ignition switch is in the On position. Depressing the heated seat switch rocker to its
momentary High or Low position provides a hard-wired resistance signal to the heated seat
module. This signal tells the module to energize the heated seat element of the selected seat and
maintain the requested temperature setting. If the heated seat switch is depressed to a different
position (Low or High) than the currently selected state, the heated seat module will change states
to support the new selection. If a heated seat switch is depressed a second time, the heated seat
module interprets the second input as a request to turn the seat heater OFF.
The High and Low LED indicator lamps in the heated seat switches receive battery current through
a fused ignition switch output (run) circuit when the ignition switch is in the On position. The ground
side of each indicator lamp is controlled by the heated seat module. This control of the switch
indicator lamps also allows the module to provide diagnostic feedback to the vehicle operator or
technician to indicate heated seat system faults by flashing the indicator lamps on and off. One
side of the incandescent back lighting bulb in each heated seat switch is connected to ground at all
times. The other side of the incandescent bulb is connected to the fused panel lamps dimmer
switch signal circuit. These bulbs are energized when the park lamps or headlamps are turned on,
and their illumination intensity is controlled by the panel lamps dimmer switch.

Parking Brake Warning Switch: Description and Operation
The park brake switch (1) is located on the park brake lever mechanism on the cowl side inner
panel below the instrument panel, to the left of the steering column. This switch includes a
spade-type output terminal (3) that connects the switch to the vehicle electrical system through a
dedicated take out and connector of the body wire harness. The output terminal is integral to the
stationary contact within a molded plastic insulator.
A locating tab on the insulator engages a slot in the park brake lever mechanism for positive switch
location. External to the insulator is a movable leaf contact with an integral grounding lug (4) on
one end and an integral actuating lever and follower (2) on the opposite end. The switch is secured
to and grounded by a single screw to the park brake lever mechanism. The park brake switch
cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
The park brake switch is a normally closed, mechanically actuated leaf contact switch that is
operated by the park brake lever mechanism. The switch is grounded through its mounting to the
park brake lever mechanism and provides a ground input to the ElectroMechanical Instrument
Cluster (EMIC) (also sometimes referred to as the Cab Control Node/CCN) on a park brake switch
sense circuit whenever the park brake is applied, and opens this circuit whenever the park brake is
released. The park brake switch sense input to the EMIC is used for control of the brake indicator
and may also be used as a logic input for other electronic features in the vehicle.
The park brake switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the EMIC processing of the park brake switch sense input requires the
use of a diagnostic scan tool.

Wheel Speed Sensor: Description and Operation
SENSOR- WHEEL SPEED-ABS-FRONT
DESCRIPTION
The ABS brake system uses 3 wheel speed sensors. A sensor is mounted to each front
hub/bearings. The third sensor is mounted on top of the rear axle differential housing.
OPERATION
The Wheel Speed Sensor consists of a magnet (1) surrounded by windings from a single strand of
wire (5). The sensor sends a small AC signal to the ABM. This signal is generated by magnetic
induction. The magnetic induction is created when a toothed sensor ring (exciter ring or tone
wheel) (4) passes the stationary magnetic WSS.
When the ring gear is rotated, the exciter ring (4) passes the tip of the WSS. As the exciter ring
tooth approaches the tip of the WSS, the magnetic lines of force expand, causing the magnetic
field to cut across the sensor's windings (5). This, in turn causes current to flow through the WSS
circuit in one direction. When the exciter ring tooth moves away from the sensor tip, the magnetic
lines of force collapse cutting the winding in the opposite direction. This causes the current to flow
in the opposite direction. Every time a tooth of the exciter ring passes the tip of the WSS, an AC
signal is generated current. Each AC signal (positive to negative signal or squarewave) is
interpreted by the ABM. It then compares the frequency of the sinewave to a time value to calculate
vehicle speed. The ABM continues to monitor the frequency to determine a deceleration rate that
would indicate a possible wheel-locking tendency.
The signal strength of any magnetic induction sensor is directly affected by: ^
Magnetic field strength; the stronger the magnetic field, the stronger the signal
^ Number of windings in the sensor; more windings provide a stronger signal
^ Exciter ring speed; the faster the exciter ring/tone wheel rotates, the stronger the signal will be
^ Distance (3) "air gap" between the exciter ring teeth and WSS; the closer the WSS is to the
exciter ring/tone wheel, the stronger the signal will be.
The WSS is not adjustable. A clearance specification has been established for manufacturing
tolerances. If the clearance is not within these specifications, then either the WSS or other
components may be damaged. The clearance between the WSS and the exciter ring is 0.005 0.050 inch.
The assembly plant performs a "Rolls Test" on every vehicle that leaves the assembly plant. One
of the test performed is a test of the WSS. To properly test the sensor, the assembly plant connects
test equipment to the Data Link Connector (DLC). This connector is located to the right of the
steering column and attached to the lower portion of the instrument panel. The rolls test terminal is
spliced to the WSS circuit. The vehicle is then driven on a set of rollers and the WSS output is
monitored for proper operation.

Cruise Control Switch: Description and Operation
Two separate switch pods operate the speed control system. The steering-wheel-mounted
switches use multiplexed circuits to provide inputs to the PCM (to the ECM for diesel) for ON, OFF,
RESUME, ACCELERATE, SET, DECEL and CANCEL modes.
The individual switches cannot be repaired. If one switch fails, the entire switch module must be
replaced.
Depending on engine control computer (JTEC having a 3- plug connector or NGC having a 4- plug
connector), 2 types of switches are used. Both types of switches are internally and externally
different. The switch used with the NGC system has an attached pigtail lead. The switch used with
the JTEC system does not have an attached pigtail lead.
When speed control is selected by depressing the ON, OFF switch, the PCM (ECM for diesel)
allows a set speed to be stored in its RAM for speed control. To store a set speed, depress the
SET switch while the vehicle is moving at a speed between approximately 35 and 85 mph. In order
for the speed control to engage, the brakes cannot be applied, nor can the gear selector be
indicating the transmission is in Park or Neutral.
The speed control can be disengaged manually by:
- Stepping on the brake pedal
- Depressing the OFF switch
- Depressing the CANCEL switch.
The speed control can be disengaged also by any of the following conditions:
- An indication of Park or Neutral (auto. trans.)
- The VSS signal increases at a rate of 10 mph per second (indicates that the co-efficient of friction
between the road surface and tires is extremely low)
- Depressing the clutch pedal (manual trans.).
- Excessive engine rpm (indicates that the transmission may be in a low gear)
- The VSS signal decreases at a rate of 10 mph per second (indicates that the vehicle may have
decelerated at an extremely high rate)
- If the actual speed is not within 20 mph of the set speed The previous disengagement conditions
are programmed for added safety.
Once the speed control has been disengaged, depressing the ACCEL switch restores the vehicle
to the target speed that was stored in the PCM's RAM (ECM for diesel).
NOTE: Depressing the OFF switch will erase the set speed stored in the PCM's/ECM's RAM.
If, while the speed control is engaged, the driver wishes to increase vehicle speed, the PCM (ECM
for diesel) is programmed for an acceleration feature. With the ACCEL switch held closed, the
vehicle accelerates slowly to the desired speed. The new target speed is stored in the
PCM's/ECM's RAM when the ACCEL switch is released. The PCM/ECM also has a "tap-up"
feature in which vehicle speed increases at a rate of approximately 2 mph for each momentary
switch activation of the ACCEL switch.
The PCM/ECM also provides a means to decelerate without disengaging speed control. To
decelerate from an existing recorded target speed, depress and hold the COAST switch until the
desired speed is reached. Then release the switch. The ON, OFF switch operates two
components: the PCM's/ECM's ON, OFF input, and the battery voltage to the brake switch.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Engine > Oil Pressure Sender > Component
Information > Diagrams > Diagram Information and Instructions > Page 644
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagrams may appear to be

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Engine > Oil Pressure Sender > Component
Information > Diagrams > Diagram Information and Instructions > Page 647
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Ambient Temperature Sensor / Switch HVAC: Description and Operation
The ambient temperature sensor is a variable resistor mounted to a bracket that is secured with a
screw to the left side of the radiator yoke, behind the radiator grille and in front of the engine
compartment.
The ambient temperature sensor cannot be adjusted or repaired and, if inoperative or damaged, it
must be replaced.
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal
sent by the Front Control Module (FCM). The resistance in the sensor changes as temperature
changes, changing the temperature sensor signal circuit voltage to the FCM. Based upon the
resistance in the sensor, the FCM senses a specific voltage on the temperature sensor signal
circuit. The FCM then translates the voltage into a temperature reading that it sent over the
Programmable Communications Interface (PCI) data bus circuit to other modules utilizing
temperature information.

Ambient Temperature Sensor / Switch HVAC: Testing and Inspection
The temperature function is supported by the ambient temperature sensor, a wiring circuit, and
Front Control Module (FCM). If any portion of the ambient temperature sensor circuit fails or if
Programmable Communications Interface (PCI) Data Bus information is missing, a (- -) will appear
in the display in place of the temperature. When the sensor is exposed to temperatures above 55°
C (130° F), or if the sensor circuit is shorted, 55° C (130° F) will appear in the display in place of
the temperature, when the sensor is exposed to temperatures below - 40° C (- 40° F) or if the
sensor circuit is open, - 40° C (- 40° F) will appear in the display.
The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test,
and Sensor Circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the
temperature display is inoperative or incorrect, test the compass mini-trip computer.
SENSOR TEST
1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable.
Disconnect the ambient temperature sensor harness
connector.
2. Measure the resistance of the ambient temperature sensor. At - 40° C (- 40° F), the sensor
resistance is 336 kilohms. At 55° C (130° F), the
sensor resistance is 2.488 kilohms. The sensor resistance should read between these two values.
If OK, refer to Sensor Circuit Test. If not OK, replace the inoperative ambient temperature sensor.
SENSOR CIRCUIT TEST
For complete circuit diagrams, The wiring information includes wiring diagrams, proper wire and
connector repair procedures, details of wire harness routing and retention, connector pin-out
information and location views for the various wire harness connectors, splices and grounds.
1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable.
Disconnect the wire harness connectors from the
ambient temperature sensor and the FCM.
2. Connect a jumper wire between the two terminals in the body half of the ambient temperature
sensor harness connector. 3. Check for continuity between the sensor return circuit and the
ambient temperature sensor signal circuit cavities of the FCM harness connector.
There should be continuity. If OK, go to Step 4. If not OK, repair the open sensor return circuit or
ambient temperature sensor signal circuit to the ambient temperature sensor as required.
4. Check for continuity between the ambient temperature sensor signal circuit cavity of the FCM
harness connector and a good ground. There should
be no continuity. If OK, test the compass mini-trip computer operation. If not OK, repair the shorted
ambient temperature sensor signal circuit as required.

control (1). The switch allows the selection of one of four different blower motor speeds and
includes an Off position.
The blower motor switch provides a ground path through the A/C-heater control. The blower motor
switch directs the ground path through the appropriate blower motor resistor wires, as required to
achieve the selected blower motor speed.
The blower motor switch is diagnosed using a DRBIII(R) scan tool.
The blower motor switch cannot be repaired and, if faulty or damaged, the entire A/C-heater control
must be replaced.

Evaporator Temperature Sensor / Switch: Description and Operation
The evaporator temperature sensor is a two-wire temperature sensing element located at the
coldest point on the face of the A/C evaporator. The probe (1) for evaporator temperature sensor is
attached to the evaporator coil fins. The wire lead (2) for evaporator temperature sensor is routed
through an opening at the back of the HVAC housing and the connector (3) is attached to the
HVAC wire harness.
The evaporator temperature sensor monitors the surface temperature of A/C evaporator and
supplies an input signal to the A/C-heater control. The A/C-heater control uses the evaporator
temperature sensor input signal to optimize A/C system performance and to protect the A/C system
from evaporator freezing. The evaporator temperature sensor will change its internal resistance in
response to the temperatures it monitors and is connected to the A/C-heater control through sensor
ground circuit and a 5-volt reference signal circuit. As the temperature of the A/C evaporator
decreases, the internal resistance of the evaporator temperature sensor decreases.
The A/C-heater control uses the monitored voltage reading as an indication of evaporator
temperature. The A/C-heater control is programmed to respond to this input by requesting the
powertrain control module (PCM) or the engine control module (ECM) (depending on engine
application) to cycle the A/C compressor clutch as necessary to optimize A/C system performance
and to protect the A/C system from evaporator freezing.
The evaporator temperature sensor is diagnosed using a DRBIII(R) scan tool.
The evaporator temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it
must be replaced.

Refrigerant Pressure Sensor / Switch: Description and Operation
The A/C pressure transducer (1) is a switch that is installed on a fitting located on the A/C
discharge line. An internally threaded fitting on the A/C pressure transducer connects it to the
externally threaded Schrader-type fitting on the A/C discharge line. A rubber O-ring seals the
connection between the A/C pressure transducer and the discharge line fitting. The A/C pressure
transducer is connected to the vehicle electrical system by a molded plastic connector with three
terminals.
The A/C pressure transducer monitors the pressures in the high side of the refrigerant system
through its connection to a fitting on the A/C discharge line. The A/C pressure transducer will
change its internal resistance in response to the pressures it monitors. A Schrader-type valve in the
A/C discharge line fitting permits the A/C pressure transducer to be removed or installed without
disturbing the refrigerant in the A/C system.
The A/C pressure transducer will change its internal resistance in response to the pressures it
monitors. The powertrain control module (PCM) or the engine control module (ECM) (depending on
engine application) provides a five volt reference signal and a sensor ground to the A/C pressure
transducer, then monitors the output voltage of the transducer on a sensor return circuit to
determine refrigerant pressure. The PCM/ECM is programmed to respond to this and other sensor
inputs by controlling the operation of the A/C compressor clutch and the radiator cooling fan to help
optimize A/C system performance and to protect the system components from damage. The PCM
will disengage the A/C compressor clutch when high side pressure rises above 3172 kPa (460 psi)
and re-engage the clutch when high side pressure drops below 1999 kPa (290 psi). The A/C
pressure transducer will also disengage the A/C compressor clutch if the high side pressure drops
below 193 kPa (28 psi) and will re-engage the clutch when the high side pressure rises above 234
kPa (34 psi). If the refrigerant pressure rises above 1655 kPa (240 psi), the PCM will actuate the
cooling fan. The A/C pressure transducer signal to the PCM/ECM will also prevent the A/C
compressor clutch from engaging when ambient temperatures are below about 10 ° C (50° F) due
to the pressure/temperature relationship of the refrigerant.The A/C pressure transducer input to the
PCM/ECM will also prevent the A/C compressor clutch from engaging when ambient temperatures
are below about 10° C (50° F) due to the pressure/temperature relationship of the refrigerant.
The A/C pressure transducer is diagnosed using a DRBIII(R) scan tool.
The A/C pressure transducer cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.

Door Switch: Description and Operation
This vehicle has up to four door ajar switches, one for each door. Each switch is concealed within
and integral to its respective door latch unit. The switches are momentary leaf contact-type units
that are actuated by the mechanisms internal to the door latch. A short pigtail wire and connector
on each door latch connects the door ajar switch to the vehicle electrical system through its
respective door wire harness. The door ajar switches cannot be adjusted or repaired and, if faulty
or damaged, the door latch unit must be replaced.
The door ajar switches are actuated by the mechanisms internal to the door latch. When a door is
closed and properly latched, its door ajar switch is an open circuit. When a door is open or only
partially latched, the door ajar switch is a closed circuit. The door ajar switches are hard wired in
series between a body ground and the Electro-Mechanical Instrument Cluster (EMIC). The EMIC
reads the hard wired door ajar switch inputs through internal pull-ups, then uses these inputs to
control many electronic functions and features of the vehicle.
The EMIC also sends the proper switch status messages to other electronic modules over the
Programmable Communications Interface (PCI) data bus network. The door ajar switches can be
diagnosed and tested using conventional diagnostic tools and methods. However, conventional
diagnostic methods may not prove conclusive in the diagnosis of the EMIC, the PCI data bus, or
the electronic messaging used to convey door ajar switch status to other modules in the vehicle.
The most reliable, efficient, and accurate means to diagnose the EMIC, the PCI data bus, and both
the hard wired and electronic message inputs and outputs affected by the door ajar switch inputs
requires the use of a diagnostic scan tool.

Component Information > Diagrams > Diagram Information and Instructions > Page 708
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Fig.7 Testing For Voltage Potential
STANDARD PROCEDURE - TESTING OF VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

2. Connect the other lead of the voltmeter to the other side of the switch, component or circuit. 3.
Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Fuel Gauge Sender: Description and Operation
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant current source is supplied to the resistor track on the fuel
gauge sending unit. This is fed directly from the Powertrain Control Module (PCM).
NOTE: For diagnostic purposes, this 12V power source can only be verified with the circuit opened
(fuel pump module electrical connector unplugged). With the connectors plugged, output voltages
will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about 8.6 volts at EMPTY for
Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The resistor track is used to
vary the voltage (resistance) depending on fuel tank float level. As fuel level increases, the float
and arm move up, which decreases voltage. As fuel level decreases, the float and arm move down,
which increases voltage. The varied voltage signal is returned back to the PCM through the sensor
return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/ setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Parking Brake Warning Switch: Description and Operation
The park brake switch (1) is located on the park brake lever mechanism on the cowl side inner
panel below the instrument panel, to the left of the steering column. This switch includes a
spade-type output terminal (3) that connects the switch to the vehicle electrical system through a
dedicated take out and connector of the body wire harness. The output terminal is integral to the
stationary contact within a molded plastic insulator.
A locating tab on the insulator engages a slot in the park brake lever mechanism for positive switch
location. External to the insulator is a movable leaf contact with an integral grounding lug (4) on
one end and an integral actuating lever and follower (2) on the opposite end. The switch is secured
to and grounded by a single screw to the park brake lever mechanism. The park brake switch
cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
The park brake switch is a normally closed, mechanically actuated leaf contact switch that is
operated by the park brake lever mechanism. The switch is grounded through its mounting to the
park brake lever mechanism and provides a ground input to the ElectroMechanical Instrument
Cluster (EMIC) (also sometimes referred to as the Cab Control Node/CCN) on a park brake switch
sense circuit whenever the park brake is applied, and opens this circuit whenever the park brake is
released. The park brake switch sense input to the EMIC is used for control of the brake indicator
and may also be used as a logic input for other electronic features in the vehicle.
The park brake switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the EMIC processing of the park brake switch sense input requires the
use of a diagnostic scan tool.

Component Information > Diagrams > Diagram Information and Instructions > Page 751
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Component Information > Diagrams > Diagram Information and Instructions > Page 754
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Backup Lamp Switch: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Backup Lamp Switch: Description and Operation
Vehicles equipped with a manual transmission have a normally open, spring-loaded plunger type
backup lamp switch (2). Vehicles with an optional electronic automatic transmission have a
Transmission Range Sensor (TRS) that is used to perform several functions, including that of the
backup lamp switch. The Transmission Range Sensor (TRS) is part of the solenoid module, which
is mounted to the top of the valve body inside the automatic transmission.
The backup lamp switch is located in a threaded hole on the side of the manual transmission
housing. The switch has a threaded body and a hex formation near the plunger end of the switch.
An integral connector receptacle at the end of the switch opposite the plunger connects the switch
to the vehicle electrical system through a take out and connector of the engine wire harness. When
installed, only the switch connector and the hex formation are visible on the outside of the
transmission housing. The backup lamp switch cannot be adjusted or repaired and, if faulty or
damaged, the entire switch unit must be replaced.
The backup lamp switch controls the flow of battery voltage to the backup lamp bulbs through an
output on the backup lamp feed circuit. The switch plunger is mechanically actuated by the
gearshift mechanism within the transmission, which will depress the switch plunger and close the
switch contacts whenever the reverse gear has been selected. The switch receives battery voltage
through a fuse in the Integrated Power Module (IPM) on a fused ignition switch output (run) circuit
whenever the ignition switch is in the On position. The backup lamp switch and circuits can be
tested using conventional diagnostic tools and methods.

Backup Lamp Switch: Testing and Inspection
1. Disconnect and isolate the battery negative cable. 2. Raise and support the vehicle. 3. Locate
and disconnect the engine wire harness connector for the backup lamp switch. 4. Check for
continuity between the two terminal pins in the backup lamp switch connector receptacle.
a. With the gear selector lever in the Reverse position, there should be continuity. b. With the gear
selector lever in any position other than Reverse, there should be no continuity.
5. If the switch fails either of these two continuity tests, replace the faulty backup lamp switch.

Brake Light Switch: Description and Operation
The brake lamp switch (2) is a three circuit, spring-loaded plunger actuated switch that is secured
to the steering column support bracket under the instrument panel on the driver side of the vehicle.
The molded plastic switch housing has an integral connector receptacle (1) containing six terminal
pins and featuring a Connector Position Assurance (CPA) lock. The switch is connected to the
vehicle electrical system through a dedicated take out of the instrument panel wire harness.
The switch plunger (3) extends through a mounting collar (4) on one end of the switch housing. The
plunger has a one time telescoping self-adjustment feature that is activated after the switch is
installed by moving an adjustment release lever (5) on the opposite end of the switch housing
clockwise, until it locks into a position that is horizontal and parallel to the connector receptacle.
An installed brake lamp switch cannot be readjusted or repaired. If the switch is damaged, faulty, or
removed from its mounting position for any reason, it must be replaced with a new unit.
The brake lamp switch controls three independent circuits. These circuits are described as follows:
- Brake Lamp Switch Circuit - A normally open brake lamp switch circuit receives a battery voltage
input, and supplies this battery voltage to the brake lamps and the Controller Antilock Brake (CAB)
on a brake lamp switch output circuit only when the brake pedal is depressed (brake lamp switch
plunger released).
- Brake Lamp Switch Signal Circuit - A normally closed brake lamp switch signal circuit receives a
direct path to ground, and supplies this ground input to the Power-train Control Module (PCM) on a
brake lamp switch sense circuit only when the brake pedal is released (brake lamp switch plunger
is depressed).
- Speed Control Circuit - A normally closed speed control circuit receives a battery voltage input
from the Powertrain Control Module on a speed control supply circuit, and supplies this battery
voltage to the speed control servo solenoids (dump, vacuum, and vent) on a speed control brake
switch output circuit only when the speed control system is turned On and the brake pedal is
released (brake lamp switch plunger is depressed).
The components of the self-adjusting brake switch plunger consist of a two-piece telescoping
plunger, a split plunger locking collar, and a release wedge. The release lever has a shaft with a
wedge that spreads the plunger locking collar to an open or released position. After the switch is
installed and the brake pedal is released, the plunger telescopes to the correct adjustment position.
When the release lever is moved to the release position, the wedge is disengaged from the locking
collar causing the collar to apply a clamping pressure to the two plunger halves, fixing the plunger
length.
The brake lamp switch is diagnosed using conventional diagnostic tools and methods.

Combination Switch: Description and Operation
MULTIFUNCTION SWITCH
The multi-function switch (3) is located on the steering column, just below the steering wheel. The
only visible components of the multi-function switch are the control stalk (2) and control knob (1)
that extend through the steering column shrouds on the left side of the column, and the hazard
warning push button (4) that extends through the shroud on the top of the column. The remainder
of the switch including its mounting provisions, its electrical connection, and the turn signal cancel
actuator (5) are concealed beneath the shrouds.
The switch housing and controls are constructed of molded black plastic. Each of the switch
controls has white International Control and Display Symbol graphics applied to it, which clearly
identify its many functions. Three integral locating posts on the switch housing, one on the top and
two on the bottom, slide into channels in a receptacle on the left side of the multi-function switch
mounting housing near the top of the steering column to ensure proper positioning of the switch.
Then two screws secure the switch to the mounting housing. A single integral connector receptacle
containing four terminal pins on the back of the switch housing connects the switch to the vehicle
electrical system through a dedicated take out and connector of the instrument panel wire harness.
The multi-function switch provides the vehicle operator with a control interface for the following
functions:
- Hazard Warning Control - The multi-function switch hazard warning push button provides two
detent positions (On and Off) to control the hazard warning lamps.
- Headlamp Beam Selection - The multi-function switch control stalk provides detent switching for
selection of the headlamp high or low beams. There is also an intermediate momentary position
that allows the headlamp high beam circuits to be momentarily flashed to provide an optical horn
feature (sometimes referred to as flash-to-pass) as an optical signalling device.
- Turn Signal Control - The multi-function switch control stalk provides momentary non-detent (lane
change) switching or detent switching with automatic cancellation for both the left and right turn
signal lamps.
- Washer Control - The multi-function switch control knob provides a momentary position for
washer system operation.
- Wiper Control - The multi-function switch control knob provides two continuous wipe switch
positions, low speed or high speed; and, an intermittent wipe mode with five delay interval
positions.
The multi-function switch cannot be adjusted or repaired. If any function of the switch is faulty, or if
the switch is damaged, the entire switch must be replaced as a unit.
The multi-function switch uses resistor multiplexing to control the many functions and features it
provides using only three hard wired output circuits. The switch receives a clean ground from the
ElectroMechanical Instrument Cluster (EMIC) (also sometimes referred to as the Cab Control
Node/CCN) on a multi-function switch return circuit. It then provides outputs to the EMIC on a
wash/beam select switch signal circuit to control washer and headlamp beam selection, on an
intermittent wiper switch signal circuit to control wipers, and on a turn lamps switch signal circuit to
control turn signal and hazard warning functions.
The multi-function switch operates as follows:
- Hazard Warning Control - The hazard warning push button of the multi-function switch is
depressed to activate the hazard warning system, and depressed again to turn the system Off.
When the push button is actuated, the multi-function switch provides an output to the EMIC, and
the EMIC responds by sending electronic hazard switch status messages to the FCM over the PCI
data bus. The FCM then energizes and flashes or de-energizes both the left and right turn signal
circuits to provide the visual hazard warning.
- Headlamp Beam Selection - The control stalk of the multi-function switch is pulled towards the
steering wheel past a detent to actuate the integral beam select switch circuitry, or to an
intermediate, momentary position before the detent to actuate the optical horn feature. Each time
the control stalk is actuated to a detent position, the opposite headlamp beam from what is
currently selected will be energized. Each time the control stalk is actuated to the momentary
position with the headlamps turned off, the headlamp high beams will be illuminated for as long as
the control stalk is held in this position. The multi-function switch provides an output to the EMIC,
and the EMIC responds by sending electronic beam select switch status messages to the FCM
over the PCI data bus. The FCM energizes or de-energizes the selected low or high beam circuits.
- Turn Signal Control - The control stalk of the multi-function switch is moved upward to activate the
right turn signal circuitry, and, downward to activate the left turn signal circuitry. The turn signal
switch has a detent position in each direction that provides turn signals with automatic cancellation,
and an intermediate, momentary position in each direction that provides turn signals only until the
control stalk is released. When the control stalk is moved to a detent turn signal switch position, the
cancel actuator extends toward the center of the steering column. A turn signal
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))

Component Information > Locations > Page 789
cancel cam that is integral to the clockspring rotates with the steering wheel and the cam lobes
contact the cancel actuator when it is extended from the multi-function switch. When the steering
wheel is rotated during a turning maneuver, one of the two turn signal cancel cam lobes will contact
the turn signal cancel actuator. The cancel actuator latches against the cancel cam rotation in the
direction opposite that which is signaled. If the left turn signal detent is selected, the lobes of the
cancel cam will ratchet past the cancel actuator when the steering wheel is rotated to the left, but
will unlatch the cancel actuator as the steering wheel rotates to the right and returns to center,
which will cancel the turn signal event and release the control stalk from the detent so it returns to
the neutral Off position. When a turn signal is activated, the multifunction switch provides an output
to the EMIC, and the EMIC responds by sending electronic turn signal switch status messages to
the FCM over the PCI data bus. The FCM energizes and flashes or de-energizes the selected left
or right turn signal circuits.
- Washer Control - The control knob on the end of the multi-function switch control stalk is
depressed towards the steering column to momentarily activate the washer pump in the washer
mode. The washer pump will continue to operate in the washer mode until the control knob is
released. The multi-function switch provides an output to the EMIC, and the EMIC responds by
sending electronic washer switch status messages to the Front Control Module (FCM) over the
Programmable Communications Interface (PCI) data bus. The FCM responds by energizing or
de-energizing the washer pump in the washer mode.
- Wiper Control - The control knob on the end of the multi-function switch control stalk is rotated to
one of the continuous wiper detents, to one of five intermittent wiper detents, or to the Off position
to select the wiper mode. The multi-function switch provides an output to the EMIC, and the EMIC
responds by sending electronic wiper switch status messages to the FCM over the PCI data bus.
The FCM responds by energizing or de-energizing the wiper on/off and high/low relays in the
Power Distribution Center (PDC) for wiper system control.
The multi-function switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the multiplexed inputs to the EMIC requires the use of a diagnostic scan
tool.

Door Switch: Description and Operation
This vehicle has up to four door ajar switches, one for each door. Each switch is concealed within
and integral to its respective door latch unit. The switches are momentary leaf contact-type units
that are actuated by the mechanisms internal to the door latch. A short pigtail wire and connector
on each door latch connects the door ajar switch to the vehicle electrical system through its
respective door wire harness. The door ajar switches cannot be adjusted or repaired and, if faulty
or damaged, the door latch unit must be replaced.
The door ajar switches are actuated by the mechanisms internal to the door latch. When a door is
closed and properly latched, its door ajar switch is an open circuit. When a door is open or only
partially latched, the door ajar switch is a closed circuit. The door ajar switches are hard wired in
series between a body ground and the Electro-Mechanical Instrument Cluster (EMIC). The EMIC
reads the hard wired door ajar switch inputs through internal pull-ups, then uses these inputs to
control many electronic functions and features of the vehicle.
The EMIC also sends the proper switch status messages to other electronic modules over the
Programmable Communications Interface (PCI) data bus network. The door ajar switches can be
diagnosed and tested using conventional diagnostic tools and methods. However, conventional
diagnostic methods may not prove conclusive in the diagnosis of the EMIC, the PCI data bus, or
the electronic messaging used to convey door ajar switch status to other modules in the vehicle.
The most reliable, efficient, and accurate means to diagnose the EMIC, the PCI data bus, and both
the hard wired and electronic message inputs and outputs affected by the door ajar switch inputs
requires the use of a diagnostic scan tool.

Headlamp Switch: Description and Operation
The headlamp switch (1) is located on the instrument panel, to the left of the steering column. Two
different switches are used. The standard switch features a three-position rotary knob (3) for
exterior lighting control and a thumbwheel (2) for panel lamps dimming and interior lighting control.
An optional switch has the same thumbwheel, but has an additional "Pull" function added to the
rotary knob for selecting the optional front fog lamps.
Each of these switches is constructed of molded plastic. The rotary knob is molded plastic and has
a raised center lever to ease operator control. The thumbwheel is also plastic and knurled. The
optional front fog lamp rotary knob is plastic with a smooth finish and an International Control and
Display Symbol icon for "Front Fog Light" applied to it. The switch face plate is also labeled with
graphics and icons to clearly identify the many functions of the rotary knob and thumbwheel.
Three screws secure the switch to the back of the cluster bezel through integral mounting flanges
that are molded to each side of the switch housing. The back of the switch housing has an integral
connector receptacle containing terminal pins that connect the switch to the vehicle electrical
system through a dedicated take out and connector of the instrument panel wire harness. A panel
dimmer controlled incandescent bulb soldered to the circuit board within the switch provides back
lighting for visibility at night, but is not serviceable. The headlamp switch cannot be repaired and, if
faulty or damaged, it must be replaced.
The headlamp switch uses two resistor multiplexed outputs to control the many functions and
features it provides. The switch receives a clean ground from the ElectroMechanical Instrument
Cluster (EMIC) (also sometimes referred to as the Cab Control Node/CCN) on a headlamp switch
return circuit. It then provides outputs to the EMIC on a headlamp switch signal circuit to control
exterior lighting functions, and on a panel lamps dimmer signal circuit to control panel dimmer and
interior lighting functions.
The switch illumination circuit receives a path to ground at all times through the left instrument
panel ground circuit. The illumination level is controlled by a Pulse-Width Modulated (PWM) output
received from the EMIC on a headlamp switch illumination control circuit. The EMIC controls this
output based upon the dimmer signal select mux input from the headlamp switch.
- Front Fog Lamps Control - For vehicles so equipped, the rotary knob on the headlamp switch is
pulled out to activate or pushed in to deactivate the optional front fog lamps. The headlamp switch
provides an output to the EMIC, and the EMIC responds by sending electronic fog lamp switch
status messages to the Front Control Module (FCM) over the Programmable Communications
Interface (PCI) data bus. The FCM responds by energizing or de-energizing the front fog lamp
relay in the Power Distribution Center (PDC).
- Exterior Lighting Control - The rotary knob on the headlamp switch is rotated to a detent position
to activate or deactivate the exterior lighting. The headlamp switch provides an output to the EMIC,
and the EMIC responds by sending electronic exterior lighting switch status messages to the FCM
over the PCI data bus. The FCM responds by energizing or de-energizing the park lamp relay in
the PDC and the high or low beam headlamp circuits. The FCM remembers which headlamp
beams were last selected using the multi-function switch, and energizes those beams by default
the next time the headlamps are turned On.
- Interior Lighting Control - The thumbwheel on the headlamp switch is rotated to the dome defeat,
dome on, parade/funeral mode, or one of the six panel dimmer detent positions to control the
interior courtesy/dome and panel lamps. The headlamp switch provides an output to the EMIC, and
the EMIC responds by providing the appropriate interior lighting control outputs through its internal
courtesy lamp driver circuits, electronic dimming level messages to other modules over the PCI
data bus, and/or the proper PWM outputs to control dimming levels through several panel dimmer
illumination control driver circuits.
The headlamp switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the multiplexed inputs to and PWM processing of the EMIC requires the
use of a diagnostic scan tool.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM (ECM Diesel) to
vary the battery charging rate. System voltage will be higher at colder temperatures and is
gradually reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20° F.

Camshaft Position Sensor: Description and Operation
The Camshaft Position Sensor (CMP) on the 5.7L V-8 engine is located below the generator on the
timing chain/case cover on the right/front side of engine.
The CMP sensor is used in conjunction with the crankshaft position sensor to differentiate between
fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective
cylinders. The sensor generates electrical pulses. These pulses (signals) are sent to the Powertrain
Control Module (PCM). The PCM will then determine crankshaft position from both the camshaft
position sensor and crankshaft position sensor.
The tonewheel (2) is located at the front of the camshaft. As the tonewheel rotates, notches (3)
pass through the sync signal generator.
When the cam gear is rotating, the sensor will detect the notches. Input voltage from the sensor to
the PCM will then switch from a low (approximately 0.3 volts) to a high (approximately 5 volts).
When the sensor detects a notch has passed, the input voltage switches back low to approximately
0.3 volts.

Crankshaft Position Sensor: Description and Operation
The Crankshaft Position (CKP) (4) sensor is mounted into the right rear side of the cylinder block. It
is positioned and bolted into a machined hole.
Engine speed and crankshaft position are provided through the CKP (Crankshaft Position) sensor.
The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The
PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this
position, along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
A tonewheel is bolted to the engine crankshaft. This tonewheel has sets of notches (3) at its outer
edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM.

Fuel Level Sensor: Description and Operation
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant current source is supplied to the resistor track on the fuel
gauge sending unit. This is fed directly from the Powertrain Control Module (PCM).
NOTE: For diagnostic purposes, this 12V power source can only be verified with the circuit opened
(fuel pump module electrical connector unplugged). With the connectors plugged, output voltages
will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about 8.6 volts at EMPTY for
Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The resistor track is used to
vary the voltage (resistance) depending on fuel tank float level. As fuel level increases, the float
and arm move up, which decreases voltage. As fuel level decreases, the float and arm move down,
which increases voltage. The varied voltage signal is returned back to the PCM through the sensor
return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/ setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Intake Air Temperature Sensor: Description and Operation
The 2-wire Intake Manifold Air Temperature (IAT) sensor is installed in the intake manifold (2) with
the sensor element extending into the air stream.
The IAT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as intake
manifold temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
The IAT sensor provides an input voltage to the Powertrain Control Module (PCM) indicating the
density of the air entering the intake manifold based upon intake manifold temperature. At key-on,
a 5-volt power circuit is supplied to the sensor from the PCM. The sensor is grounded at the PCM
through a low-noise, sensor-return circuit.
The PCM uses this input to calculate the following:
- Injector pulse-width
- Adjustment of spark timing (to help prevent spark knock with high intake manifold air-charge
temperatures)
The resistance values of the IAT sensor is the same as for the Engine Coolant Temperature (ECT)
sensor.

Knock Sensor: Description and Operation
The sensors are used only with 3.7L V-6, 4.7L V-8 and 5.7L V-8 engines. On 3.7L V-6 and 4.7L
V-8 engines, the 2 knock sensors are bolted into the cylinder block under the intake manifold.
On 5.7L V-8 engines, 2 knock sensors are also used. These are bolted into each side of the
cylinder block (outside) under the exhaust manifold.
3.7L V-6/4.7L V-8/5.7L V-8 Engines Only
Two knock sensors are used; one for each cylinder bank. When the knock sensor detects a knock
in one of the cylinders on the corresponding bank, it sends an input signal to the Powertrain Control
Module (PCM). In response, the PCM retards ignition timing for all cylinders by a scheduled
amount.
Knock sensors contain a piezoelectric material which constantly vibrates and sends an input
voltage (signal) to the PCM while the engine operates. As the intensity of the crystal's vibration
increases, the knock sensor output voltage also increases.
The voltage signal produced by the knock sensor increases with the amplitude of vibration. The
PCM receives the knock sensor voltage signal as an input. If the signal rises above a
predetermined level, the PCM will store that value in memory and retard ignition timing to reduce
engine knock. If the knock sensor voltage exceeds a preset value, the PCM retards ignition timing
for all cylinders. It is not a selective cylinder retard.
The PCM ignores knock sensor input during engine idle conditions. Once the engine speed
exceeds a specified value, knock retard is allowed.
Knock retard uses its own short term and long term memory program.
Long term memory stores previous detonation information in its battery-backed RAM. The
maximum authority that long term memory has over timing retard can be calibrated.
NOTE: Over or under tightening the sensor mounting bolts will affect knock sensor performance,
possibly causing improper spark control. Always use the specified torque when installing the knock
sensors.
Short term memory is allowed to retard timing up to a preset amount under all operating conditions
(as long as rpm is above the minimum rpm) except at Wide Open Throttle (WOT). The PCM, using
short term memory, can respond quickly to retard timing when engine knock is detected. Short term
memory is lost any time the ignition key is turned off.

Page 875
Manifold Pressure/Vacuum Sensor: Description and Operation
The Manifold Absolute Pressure (MAP) sensor is mounted to the front of the intake manifold air
plenum box.
The MAP sensor is used as an input to the Powertrain Control Module (PCM). It contains a silicon
based sensing unit to provide data on the manifold vacuum that draws the air/fuel mixture into the
combustion chamber. The PCM requires this information to determine injector pulse width and
spark advance. When manifold absolute pressure (MAP) equals Barometric pressure, the pulse
width will be at maximum.
A 5 volt reference is supplied from the PCM and returns a voltage signal to the PCM that reflects
manifold pressure. The zero pressure reading is 0.5V and full scale is 4.5V. For a pressure swing
of 0-15 psi, the voltage changes 4.0V. To operate the sensor, it is supplied a regulated 4.8 to 5.1
volts. Ground is provided through the low-noise, sensor return circuit at the PCM.
The MAP sensor input is the number one contributor to fuel injector pulse width. The most
important function of the MAP sensor is to determine barometric pressure. The PCM needs to
know if the vehicle is at sea level or at a higher altitude, because the air density changes with
altitude. It will also help to correct for varying barometric pressure. Barometric pressure and altitude
have a direct inverse correlation; as altitude goes up, barometric goes down. At key-on, the PCM
powers up and looks at MAP voltage, and based upon the voltage it sees, it knows the current
barometric pressure (relative to altitude). Once the engine starts, the PCM looks at the voltage
again, continuously every 12 milliseconds, and compares the current voltage to what it was at
key-on. The difference between current voltage and what it was at key-on, is manifold vacuum.
During key-on (engine not running) the sensor reads (updates) barometric pressure. A normal
range can be obtained by monitoring a known good sensor. As the altitude increases, the air
becomes thinner (less oxygen). If a vehicle is started and driven to a very different altitude than
where it was at key-on, the barometric pressure needs to be updated. Any time the PCM sees
Wide Open Throttle (WOT), based upon Throttle Position Sensor (TPS) angle and RPM, it will
update barometric pressure in the MAP memory cell. With periodic updates, the PCM can make its
calculations more effectively.
The PCM uses the MAP sensor input to aid in calculating the following:
- Manifold pressure
- Barometric pressure
- Engine load
- Injector pulse-width
- Spark-advance programs
- Shift-point strategies (certain automatic transmissions only)
- Idle speed
- Decel fuel shutoff
The MAP sensor signal is provided from a single piezoresistive element located in the center of a
diaphragm. The element and diaphragm are both made of silicone. As manifold pressure changes,
the diaphragm moves causing the element to deflect, which stresses the silicone. When silicone is
exposed to stress, its resistance changes. As manifold vacuum increases, the MAP sensor input
voltage decreases proportionally. The sensor also contains electronics that condition the signal and
provide temperature compensation.
The PCM recognizes a decrease in manifold pressure by monitoring a decrease in voltage from the
reading stored in the barometric pressure memory cell. The MAP sensor is a linear sensor;
meaning as pressure changes, voltage changes proportionately. The range of voltage output from
the sensor is usually between 4.6 volts at sea level to as low as 0.3 volts at 26 in. of Hg. Barometric
pressure is the pressure exerted by the atmosphere upon an

Page 876
object. At sea level on a standard day, no storm, barometric pressure is approximately 29.92 in Hg.
For every 100 feet of altitude, barometric pressure drops 0.10 in. Hg. If a storm goes through, it can
change barometric pressure from what should be present for that altitude. You should know what
the average pressure and corresponding barometric pressure is for your area.

Power Steering Pressure Switch: Description and Operation
SWITCH-POWER STEERING PRESSURE
DESCRIPTION
A pressure sensing switch is used in the power steering system. It is mounted on the high-pressure
steering hose. This switch will only be used with on HD vehicles with the 5.7L engines. There is no
pressure switch used for the 3.7L, 4.7L, 5.9L engines or the 5.7L LD vehicle pump.
OPERATION
The switch is used on the 5.7L V-8 engines HD vehicles only.
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high steering pump load and low engine rpm; such as
during parking maneuvers. The PCM increases the idle speed through the Idle Air Control (IAC)
motor. This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the Normally
Closed (NC) switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

Transmission Position Switch/Sensor: Description and Operation
SENSOR-TRANSMISSION RANGE
DESCRIPTION
The Transmission Range Sensor (TRS) is part of the solenoid module, which is mounted to the top
of the valve body inside the transmission. The Transmission Range Sensor (TRS) has five switch
contact pins that: ^
Determine shift lever position
^ Supply ground to the Starter Relay in Park and Neutral only.
^ Supply +12 V to the backup lamps in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

Camshaft Position Sensor: Description and Operation
The Camshaft Position Sensor (CMP) on the 5.7L V-8 engine is located below the generator on the
timing chain/case cover on the right/front side of engine.
The CMP sensor is used in conjunction with the crankshaft position sensor to differentiate between
fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective
cylinders. The sensor generates electrical pulses. These pulses (signals) are sent to the Powertrain
Control Module (PCM). The PCM will then determine crankshaft position from both the camshaft
position sensor and crankshaft position sensor.
The tonewheel (2) is located at the front of the camshaft. As the tonewheel rotates, notches (3)
pass through the sync signal generator.
When the cam gear is rotating, the sensor will detect the notches. Input voltage from the sensor to
the PCM will then switch from a low (approximately 0.3 volts) to a high (approximately 5 volts).
When the sensor detects a notch has passed, the input voltage switches back low to approximately
0.3 volts.

Crankshaft Position Sensor: Description and Operation
The Crankshaft Position (CKP) (4) sensor is mounted into the right rear side of the cylinder block. It
is positioned and bolted into a machined hole.
Engine speed and crankshaft position are provided through the CKP (Crankshaft Position) sensor.
The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The
PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this
position, along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
A tonewheel is bolted to the engine crankshaft. This tonewheel has sets of notches (3) at its outer
edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM.

Knock Sensor: Description and Operation
The sensors are used only with 3.7L V-6, 4.7L V-8 and 5.7L V-8 engines. On 3.7L V-6 and 4.7L
V-8 engines, the 2 knock sensors are bolted into the cylinder block under the intake manifold.
On 5.7L V-8 engines, 2 knock sensors are also used. These are bolted into each side of the
cylinder block (outside) under the exhaust manifold.
3.7L V-6/4.7L V-8/5.7L V-8 Engines Only
Two knock sensors are used; one for each cylinder bank. When the knock sensor detects a knock
in one of the cylinders on the corresponding bank, it sends an input signal to the Powertrain Control
Module (PCM). In response, the PCM retards ignition timing for all cylinders by a scheduled
amount.
Knock sensors contain a piezoelectric material which constantly vibrates and sends an input
voltage (signal) to the PCM while the engine operates. As the intensity of the crystal's vibration
increases, the knock sensor output voltage also increases.
The voltage signal produced by the knock sensor increases with the amplitude of vibration. The
PCM receives the knock sensor voltage signal as an input. If the signal rises above a
predetermined level, the PCM will store that value in memory and retard ignition timing to reduce
engine knock. If the knock sensor voltage exceeds a preset value, the PCM retards ignition timing
for all cylinders. It is not a selective cylinder retard.
The PCM ignores knock sensor input during engine idle conditions. Once the engine speed
exceeds a specified value, knock retard is allowed.
Knock retard uses its own short term and long term memory program.
Long term memory stores previous detonation information in its battery-backed RAM. The
maximum authority that long term memory has over timing retard can be calibrated.
NOTE: Over or under tightening the sensor mounting bolts will affect knock sensor performance,
possibly causing improper spark control. Always use the specified torque when installing the knock
sensors.
Short term memory is allowed to retard timing up to a preset amount under all operating conditions
(as long as rpm is above the minimum rpm) except at Wide Open Throttle (WOT). The PCM, using
short term memory, can respond quickly to retard timing when engine knock is detected. Short term
memory is lost any time the ignition key is turned off.

Air Bag Deactivation Switch: Description and Operation
The passenger airbag on/off switch (1) is standard equipment on all standard cab versions of this
model when they are equipped with the dual front airbag system. This switch is a two-position,
resistor multiplexed switch with a single integral red Light-Emitting Diode (LED), and a non-coded
key cylinder-type actuator. The switch is located in the lower right corner of instrument panel center
bezel, near the center of instrument panel to make the Off indicator (3) visible to all front seat
occupants.
When the switch is in its installed position, the only components visible through the dedicated
opening of the cluster bezel are the switch face plate (2) and nomenclature, and the key cylinder
actuator (4). The "Off" position of the switch is illuminated when this switch position is selected,
while the "On" position of the switch is designated by text imprinted upon the face plate of the
switch, but is not illuminated. The remainder of the switch is concealed behind the switch face plate
and the instrument panel center bezel.
The passenger airbag on/off switch housing is constructed of molded plastic and has three integral
mounting tabs. These mounting tabs are used to secure the switch to the back of the molded
plastic switch face plate with three small screws. The molded plastic face plate also has three
integral mounting tabs that are used to secure the switch and face plate unit to the instrument
panel center bezel with three additional screws.
A molded plastic connector receptacle on the back of the switch housing connects the switch to the
vehicle electrical system through a dedicated take out and connector of the instrument panel wire
harness. The molded plastic harness connector insulator is keyed and latched to ensure proper
and secure switch electrical connections. The passenger airbag on/off switch cannot be adjusted or
repaired and, if faulty or damaged, the switch must be replaced.
The passenger airbag on/off switch allows the customer to turn the passenger airbag function On
or Off to accommodate certain uses of the right front seating position where airbag protection may
not be desired. See the vehicle glove box for specific recommendations on when to enable or
disable the passenger airbag. The Off indicator of the switch will be illuminated whenever the
switch is turned to the Off position and the ignition switch is in the On position.
The ignition key is the only key or object that should ever be inserted into the key cylinder actuator
of the switch. The on/off switch requires only a partial key insertion to fully depress a spring-loaded
locking plunger. The spring-loaded locking plunger prevents the user from leaving the key in the
switch. The key will be automatically ejected when force is not applied. To actuate the passenger
airbag on/off switch, insert the ignition key into the switch key actuator far enough to fully depress
the plunger, then rotate the actuator to the desired switch position.
When the switch key actuator is rotated to its clockwise stop (the key actuator slot will be aligned
with the Off indicator), the Off indicator is illuminated and the passenger airbag is disabled. When
the switch is rotated to its counterclockwise stop (the key actuator slot will be in a vertical position),
the Off indicator will be extinguished and the passenger airbag is enabled.
The passenger airbag on/off switch connects one of two internal resistors in series between the
passenger airbag mux switch sense and passenger airbag mux switch return circuits of the Airbag
Control Module (ACM). The ACM continually monitors the resistance in these circuits to determine
the switch position that has been selected.
When the switch is in the Off position, the ACM provides a ground input to the switch through the
passenger airbag indicator driver circuit, which energizes the Light-Emitting Diode (LED) that
illuminates the Off indicator of the switch. The ACM will also illuminate the Off indicator of the
switch for about seven seconds each time the ignition switch is turned to the On position as a bulb
test.
The ACM will store a Diagnostic Trouble Code (DTC) for any fault it detects in the passenger
airbag on/off switch or Off indicator circuits, and will illuminate the airbag indicator in the instrument
cluster if a fault is detected. For proper diagnosis of the passenger airbag on/off switch or the ACM,
a diagnostic scan tool is required.

Impact Sensor: Description and Operation
Two side impact sensors (1) are used on this model when it is equipped with the optional side
curtain air-bags, one each for the left and right sides of the vehicle. These sensors are mounted
remotely from the bi-directional safing sensor that is internal to the Air-bag Control Module (ACM).
Each side impact sensor is secured with a nut within the right or left B-pillar just above the front
seat belt retractors and behind the lower B-pillar trim within the passenger compartment. The
sensor housing has an integral connector receptacle (2), an integral mounting stud (3), and an
integral anti-rotation pin.
The right and left side impact sensors are identical in construction and calibration. A cavity in the
center of the molded black plastic impact sensor housing contains the electronic circuitry of the
sensor which includes an electronic communication chip and an electronic impact sensor. Potting
material fills the cavity to seal and protect the internal electronic circuitry and components. The side
impact sensors are each connected to the vehicle electrical system through a dedicated take out
and connector of the body wire harness.
The side impact sensors cannot be repaired or adjusted and, if damaged or faulty, they must be
replaced.
The side impact sensors are electronic accelerometers that sense the rate of vehicle deceleration,
which provides verification of the direction and severity of an impact. Each sensor also contains an
electronic communication chip that allows the unit to communicate the sensor status as well as
sensor fault information to the microprocessor in the Airbag Control Module (ACM).
The ACM microprocessor continuously monitors all of the side passive restraint system electrical
circuits to determine the system readiness. If the ACM detects a monitored system fault, it sets a
Diagnostic Trouble Code (DTC) and controls the airbag indicator operation accordingly. The impact
sensors each receive battery current and ground through dedicated left and right sensor plus and
minus circuits from the ACM. The impact sensors and the ACM communicate by modulating the
voltage in the sensor plus circuit.
The hard wired circuits between the side impact sensors and the ACM may be diagnosed and
tested using conventional diagnostic tools and procedures. However, conventional diagnostic
methods will not prove conclusive in the diagnosis of the ACM, the impact sensors, or the
electronic message inputs to or outputs from the impact sensors. The most reliable, efficient, and
accurate means to diagnose the impact sensors, the ACM, and the electronic message
communication between the sensors and the ACM requires the use of a diagnostic scan tool.

Seat Belt Buckle Switch: Description and Operation
The seat belt switch is a small, normally open, single pole, single throw, leaf contact, momentary
switch. Only one seat belt switch is installed in the vehicle, and it is integral to the buckle of the
driver side front seat belt buckle-half, located on the inboard side of the driver side front seat track
(4). The seat belt switch is connected to the vehicle electrical system through a two-wire pigtail wire
(3) and connector on the seat belt buckle-half (1), which is connected to a wire harness connector
and take out of the seat wire harness routed beneath the driver side front seat cushion (2) in the
passenger compartment.
The seat belt switch cannot be adjusted or repaired and, if faulty or damaged, the entire driver side
front seat belt buckle-half unit must be replaced.
The seat belt switch is designed to control a path to ground for the seat belt switch sense input of
the ElectroMechanical Instrument Cluster (EMIC). When the driver side front seat belt tip-half is
inserted into the seat belt buckle, the switch closes the path to ground; and, when the driver side
front seat belt tip-half is removed from the seat belt buckle, the switch opens the ground path. The
switch is actuated by the latch mechanism within the seat belt buckle.
The seat belt switch is connected in series between ground and the seat belt switch sense input of
the instrument cluster. The seat belt switch receives ground at all times through its pigtail wire
connection to the seat wire harness from a take out of the body wire harness. An eyelet terminal
connector on the body wire harness ground take out is secured beneath a ground screw on the left
cowl side inner panel, beneath the instrument panel. The seat belt switch may de diagnosed using
conventional diagnostic tools and methods.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM (ECM Diesel) to
vary the battery charging rate. System voltage will be higher at colder temperatures and is
gradually reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20° F.

Power Steering Pressure Switch: Description and Operation
SWITCH-POWER STEERING PRESSURE
DESCRIPTION
A pressure sensing switch is used in the power steering system. It is mounted on the high-pressure
steering hose. This switch will only be used with on HD vehicles with the 5.7L engines. There is no
pressure switch used for the 3.7L, 4.7L, 5.9L engines or the 5.7L LD vehicle pump.
OPERATION
The switch is used on the 5.7L V-8 engines HD vehicles only.
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high steering pump load and low engine rpm; such as
during parking maneuvers. The PCM increases the idle speed through the Idle Air Control (IAC)
motor. This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the Normally
Closed (NC) switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

Fluid Pressure Sensor/Switch: Description and Operation
SENSOR-LINE PRESSURE
DESCRIPTION
The TCM utilizes a closed-loop system to control transmission line pressure. The system contains
a variable force style solenoid, the Pressure Control Solenoid, mounted on the side of the solenoid
and pressure switch assembly. The solenoid is duty cycle controlled by the TCM to vent the
unnecessary line pressure supplied by the oil pump back to the sump. The system also contains a
variable pressure style sensor, the Line Pressure Sensor, which is a direct input to the TCM. The
line pressure solenoid monitors the transmission line pressure and completes the feedback loop to
the TCM. The TCM uses this information to adjust its control of the pressure control solenoid to
achieve the desired line pressure.
OPERATION
The TCM calculates the desired line pressure based upon inputs from the transmission and engine.
The TCM calculates the torque input to the transmission and uses that information as the primary
input to the calculation. The line pressure is set to a predetermined value during shifts and when
the transmission is in the PARK and NEUTRAL positions. This is done to ensure consistent shift
quality. During all other operation, the actual line pressure is compared to the desired line pressure
and adjustments are made to the pressure control solenoid duty cycle.

Overdrive Switch: Description and Operation
SWITCH-TOW/HAUL OVERDRIVE
DESCRIPTION
The tow/haul overdrive OFF (control) switch is located in the shift lever arm. The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the tow/haul overdrive
OFF mode to be entered and the Tow/Haul lamp to be illuminated. Pressing the switch a second
time causes normal overdrive operation to be restored and the tow/haul lamp to be turned off. The
tow/haul overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the tow/haul overdrive switch is turned to the OFF position, or when illuminated by the
transmission control module.

SENSOR-TRANSMISSION RANGE
DESCRIPTION
The Transmission Range Sensor (TRS) is part of the solenoid module, which is mounted to the top
of the valve body inside the transmission. The Transmission Range Sensor (TRS) has five switch
contact pins that: ^
Determine shift lever position
^ Supply ground to the Starter Relay in Park and Neutral only.
^ Supply +12 V to the backup lamps in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

SENSOR-INPUT SPEED
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following: ^
Transmission gear ratio
^ Speed ratio error detection
^ CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following: . Torque converter clutch slippage . Torque converter element speed ratio.

SENSOR-TRANSMISSION TEMPERATURE
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: ^
Battery (ambient) temperature
^ Engine coolant temperature
^ In-gear run time since start-up

SWITCH-SELECTOR
DESCRIPTION
The selector switch assembly (1) is mounted in the left side of the vehicle's Instrument Panel (IP)
and consists of a rotary knob connected to a resistive network for the mode and range shift
selections. Also located in this assembly is a recessed, normally open momentary switch for
making shifts into and out of transfer case NEUTRAL. A pen, or similar instrument, is used to make
a NEUTRAL shift selection, thus reducing the likelihood of an inadvertent shift request.
The selector switch also contains four light emitting diode's (LED's) to indicate the transfer case
position and whether a shift is in progress.
OPERATION
As the position of the selector switch varies, the resistance between the Mode Sensor supply
voltage pin and the Mode Sensor output will vary. Hardware, software, and calibrations within the
Transfer Case Control Module (TCCM) are provided that interpret the selector switch resistance as
given in the table below:
SELECTOR SWITCH INTERPRETATION
SELECTOR SWITCH INTERPRETATION
For resistances between the ranges B-E shown for each valid position (T-Case NEUTRAL, 4LO,
4HI, 2WD), the TCCM may interpret the resistance as: ^
either of the neighboring valid positions.
^ as an invalid fault position.
For resistances between the ranges E and F shown for 2WD and in-between positions, the TCCM
may interpret the resistance as: ^
the 2WD position.
^ an invalid fault position.
^ a valid in-between position.
For resistances between the ranges F and G shown for in-between positions and fault condition
(open), the TCCM may interpret the resistance as: ^
a valid in-between position.
^ an invalid fault position.

For resistances between the ranges A and B shown for the fault condition (short) and, T-Case
NEUTRAL, the TCCM may interpret the resistance as: ^
the T-Case NEUTRAL position.
^ an invalid fault position.
The LED's in the selector assembly are illuminated/flashed in the following manner to indicate a
particular condition or state. ^
A solidly illuminated LED indicates a successfully completed shift and the current operating mode
of the transfer case. While a shift has been requested but not yet completed, the LED for the
desired transfer case position is flashed.
^ A flashing operating mode LED for the desired gear indicates that a shift to that position has been
requested, but all of the driver controllable conditions have not been met. This is in an attempt to
notify the driver that the transmission needs to be put into NEUTRAL, the vehicle speed is too
great, or some other condition outlined (other than a diagnostic failure that would prevent this shift)
elsewhere is not met. Note that this flashing will continue indefinitely until the conditions are
eventually met, or the selector switch position is changed, or if diagnostic routines no longer allow
the requested shift.
^ If the driver attempts to make a shift into transfer case NEUTRAL, and any of the driver
controllable conditions are not met, the request will be ignored until all of the conditions are met or
until the NEUTRAL select button is released. Additionally the neutral lamp will flash, or begin to
flash while the button is depressed and operator controllable conditions are not being met. All of
the LED's except the Neutral will flash if any of the operator controllable conditions for shifting are
not met while the Neutral button is depressed. This "toggle" type of feature is necessary because
the TCCM would interpret another request immediately after the shift into transfer case NEUTRAL
has completed.
^ No LED's illuminated indicate a fault in the transfer case control system.

eventually met, or the selector switch position is changed, or if diagnostic routines no longer allow
the requested shift.
^ If the driver attempts to make a shift into transfer case NEUTRAL, and any of the driver
controllable conditions are not met, the request will be ignored until all of the conditions are met or
until the NEUTRAL select button is released. Additionally the neutral lamp will flash, or begin to
flash while the button is depressed and operator controllable conditions are not being met. All of
the LED's except the Neutral will flash if any of the operator controllable conditions for shifting are
not met while the Neutral button is depressed. This "toggle" type of feature is necessary because
the TCCM would interpret another request immediately after the shift into transfer case NEUTRAL
has completed.
^ No LED's illuminated indicate a fault in the transfer case control system.

SENSOR-MODE
DESCRIPTION
The transfer case mode sensor (1) is an electronic device whose output can be interpreted to
indicate the shift motor shaft's rotary position. The sensor consists of a magnetic ring and four Hall
Effect Transistors to create a 4 channel digital device (non-contacting) whose output converts the
motor shaft position into a coded signal. The TCCM must supply 5VDC (+/- 0.5v) to the sensor and
monitor the shift motor position. The four channels are denoted A, B. C, and D. The sensor is
mechanically linked to the shaft of the cam which causes the transfer case shifting. The mode
sensor draws less than 53 mA.
OPERATION
During normal vehicle operation, the Transfer Case Control Module (TCCM) monitors the mode
sensor outputs at least every 250 (+/-50) milliseconds when the shift motor is stationary and 400
microseconds when the shift motor is active. A mode sensor signal between 3.8 Volts and 0.8 Volts
is considered to be undefined.
Refer to SECTOR ANGLES vs. TRANSFER CASE POSITION for the relative angles of the transfer
case shift sector versus the interpreted transfer case gear operating mode. Refer to MODE
SENSOR CHANNEL STATES for the sensor codes returned to the TCCM for each transfer case
mode sensor position. The various between gears positions can also be referred as the transfer
case's coarse position. These coarse positions come into play during shift attempts.

Rear Defogger Switch: Description and Operation
The switch for the rear window defogger (EBL) system (1) is integrated into the A/C-heater control
(2), which is located in the center of the instrument panel. When the rear window defogger switch is
activated, the timing circuit integral to the A/C-heater control operates the rear window defogger
(EBL) relay and the heated mirror relay.
When the relays are activated, current is directed to the rear window defogger and the outside rear
view mirror grids. The grids heat the rear window and rear view mirror glass to help clear the
surfaces of fog or frost.
An LED indicator will illuminate when the rear window defogger switch is activated. When the
switch is activated, it energizes the timing circuit integral to the A/C-heater control, which then
activates the rear window defogger (EBL) relay and the heated mirror relay. The EBL relay controls
the current flow to the grids of the rear window defogger.
The EBL system will be on for approximately ten minutes or until the rear window defogger switch
or the ignition switch is turned off.
The rear window defogger switch and the rear window defogger LED indicator cannot be repaired
and, if faulty or damaged, the A/C-heater control must be replaced.

Washer Fluid Level Switch: Description and Operation
The washer fluid level switch is a single pole, single throw reed-type switch mounted on the side of
the washer reservoir (4) in the engine compartment. Only the molded plastic switch mounting
flange (1) and the integral connector receptacle (8) are visible when the switch is installed in the
reservoir. A short nipple formation (2) extends from the inner surface of the switch mounting flange,
and a barb on the nipple is pressed through a rubber grommet seal (5) installed in the mounting
hole of the reservoir.
A small, molded plastic float (3) has two pivot pins (6) near its center that are snapped into two
receptacles near the ends of two stanchions that extend toward the float from the nipple formation.
A small magnet (7) is secured within the end of the float nearest the nipple, and a reed switch is
concealed within the nipple. A diagnostic resistor is connected between the two switch terminals
within the switch mounting flange. The washer fluid level switch cannot be adjusted or repaired. If
faulty or damaged, the switch must be replaced.
The washer fluid level switch uses a pivoting, oblong float to monitor the level of the washer fluid in
the washer reservoir. The float contains a small magnet. When the float pivots, the proximity of this
magnet to a stationary reed switch within the nipple formation of the switch changes. When the
fluid level in the washer reservoir is at or above the float level, the float moves to a vertical position,
the influence of the float magnetic field is removed from the reed switch, and the normally open
reed switch contacts open. When the fluid level in the washer reservoir falls below the level of the
pivoting float, the float moves to a horizontal position, the influence of the float magnetic field is
applied to the reed switch, and the contacts of the normally open reed switch close.
The washer fluid level switch is connected to the vehicle electrical system through a dedicated take
out and connector of the right (except SRT-10 and diesel engines) or left (SRT-10 and diesel
engines only) headlamp and dash wire harness. The switch is connected in series between a clean
ground output of the Front Control Module (FCM) on a sensor return circuit and the washer fluid
switch sense input to the FCM. When the switch closes, the FCM senses the ground on the washer
fluid switch sense circuit. The FCM is programmed to respond to this input by sending an electronic
washer fluid indicator lamp-on message to the instrument cluster over the Programmable
Communications Interface (PCI) data bus. The instrument cluster responds to this message by
illuminating the washer fluid indicator and by sounding an audible chime tone warning.
The washer fluid level switch may be diagnosed and tested using conventional diagnostic tools and
procedures. However, conventional diagnostic methods may not prove conclusive in the diagnosis
of the instrument cluster, the FCM, or the electronic message inputs to or outputs from the
instrument cluster and the FCM that control the operation of the washer fluid visual and/or audible
indicators. The most reliable, efficient, and accurate means to diagnose the washer fluid level
indicator, the instrument cluster, the FCM, or the electronic message inputs and outputs related to
the washer fluid indicator requires the use of a diagnostic scan tool.

Alignment: Description and Operation
WHEEL ALIGNMENT
DESCRIPTION
NOTE: Suspension components with rubber/urethane bushings should be tightened with the
vehicle at normal ride height. It is important to have the springs supporting the weight of the vehicle
when the fasteners are torqued. If springs are not at their normal ride position, vehicle ride comfort
could be affected and premature bushing wear may occur.
Wheel alignment involves the correct positioning of the wheels in relation to the vehicle. The
positioning is accomplished through suspension and steering linkage adjustments. An alignment is
considered essential for efficient steering, good directional stability and to minimize tire wear. The
most important measurements of an alignment are caster, camber and toe.
CAUTION: Never attempt to modify suspension or steering components by heating or bending.
OPERATION
^ CASTER is the forward or rearward tilt of the steering knuckle from vertical. Tilting the top of the
knuckle forward provides less positive caster. Tilting the top of the knuckle rearward provides more
positive caster. Positive caster promotes directional stability. This angle enables the front wheels to
return to a straight ahead position after turns
^ CAMBER is the inward or outward tilt of the wheel relative to the center of the vehicle. Tilting the
top of the wheel inward provides negative camber. Tilting the top of the wheel outward provides
positive camber. Incorrect camber will cause wear on the inside or outside edge of the tire
^ TOE is the difference between the leading inside edges and trailing inside edges of the front tires.
Wheel toe position out of specification cause's unstable steering, uneven tire wear and steering
wheel off- center. The wheel toe position is the final front wheel alignment adjustment
^ THRUST ANGLE is the angle of the rear axle relative to the centerline of the vehicle. Incorrect
thrust angle can cause off-center steering and excessive tire wear. This angle is not adjustable,
damaged component(s) must be replaced to correct the thrust angle

PRE-ALIGNMENT INSPECTION
Before starting wheel alignment, the following inspection and necessary corrections must be
completed. Refer to Suspension and Steering System Diagnosis Chart for additional information. 1.
Inspect tires for size, air pressure and tread wear. 2. Inspect front wheel bearings for wear. 3.
Inspect front wheels for excessive radial or lateral runout and balance. 4. Inspect ball studs, linkage
pivot points and steering gear for looseness, roughness or binding. 5. Inspect suspension
components for wear and noise. 6. On 4x4 vehicles check suspension height (LD only). 7. Road
test the vehicle.

Height Measurement - 4WD (LD)
HEIGHT MEASUREMENT - 4WD (LD)
The vehicle suspension height MUST be measured and adjusted before performing wheel
alignment procedure. Also when front suspension components have been replaced. This measure
must be performed with the vehicle supporting it's own weight and taken on both sides of the
vehicle. 1. Inspect tires and set to correct pressure. 2. Jounce the front of the vehicle.
6. If value is greater than 61 mm (2.4 inches), tighten the torsion bar bolt until the specification is
achieved. 7. If value is less than 55 mm (2.1 inches), loosen the torsion bar bolt until the
specification is achieved. 8. Repeat the previous steps until the ride height is within specifications.
Height Adjustment - 4WD (LD)
HEIGHT ADJUSTMENT - 4WD (LD)
The vehicle suspension height MUST be measured and adjusted before performing wheel
alignment procedure. Also when front suspension components have been replaced. This
measurement must be performed with the vehicle supporting it's own weight and taken on both
sides of the vehicle.
To adjust the vehicle height turn the torsion bar adjustment bolt CLOCKWISE to raise the vehicle
and COUNTER CLOCKWISE to lower the vehicle.
CAUTION: ALWAYS raise the vehicle to the correct suspension height, NEVER lower the vehicle
to obtain the correct suspension height. If the vehicle suspension height is too high, lower the
vehicle below the height specification. Then raise the vehicle to the correct suspension height
specification. This will insure the vehicle maintains the proper suspension height.
NOTE: If a height adjustment has been made, perform height measurement again on both sides of
the vehicle.

pivot bolt of the upper control arm in or out. Then move the other pivot bolt of the upper control arm
in the opposite direction. Install special tool 8876 between the top of the upper control arm bracket
and the upper control arm (on 1500 series 4X2 & 4X4). Install special tool 8876 between the bottom
of the upper control arm bracket pressing the tool against the frame and the upper control arm (on
2500/3500 series 4X2) in order to move the upper control arm outwards for proper adjustment with
the vehicle at normal ride height.
To increase positive caster angle, move the rear position (2) of the upper control arm inward
(toward the engine). Move the front (1) of the upper control arm outward (away from the engine)
slightly until the original camber angle is obtained using special tool 8876 to move the upper control
arm for proper adjustment.
CAMBER
Move both pivot bolts of the upper control arm together in or out. This will change the camber angle
significantly and little effect on the caster angle using special tool 8876 to move the upper control
arm (4) for proper adjustment.
After adjustment is made tighten the upper control arm nuts to proper torque specification.
TOE ADJUSTMENT
The wheel toe position adjustment is the final adjustment. 1. Start the engine and turn wheels both
ways before straightening the wheels. Secure the steering wheel with the front wheels in the
straight-ahead
position.

Alignment: Service and Repair Link/Coil
ALIGNMENT LINK/COIL SUSPENSION
Before each alignment reading the vehicle should be jounced (rear first, then front). Grasp each
bumper at the center and jounce the vehicle up and down several times. Always release the
bumper in the down position. Set the front end alignment to specifications while the vehicle is in its
NORMALLY LOADED CONDITION.
CAMBER: The wheel camber angle is preset and is not adjustable.
CASTER: Check the caster of the front axle for correct angle. Be sure the axle is not bent or
twisted. Road test the vehicle and make left and right turn. Observe the steering wheel
return-to-center position. Low caster will cause poor steering wheel returnability. Caster can be
adjusted by rotating the cams (3) on the lower suspension arm.
TOE POSITION: The wheel toe position adjustment should be the final adjustment.
1. Start the engine and turn wheels both ways before straightening the wheels. Center and Secure
the steering wheel and turn off engine. 2. Loosen the adjustment sleeve clamp bolts. 3. Adjust the
right wheel toe position with the drag link. Turn the sleeve until the right wheel is at the correct
TOE-IN position. Position clamp bolts
to their original position and tighten to specifications. Make sure the toe setting does not change
during clamp tightening.
4. Adjust left wheel toe position with tie rod at left knuckle. Turn the sleeve until the left wheel is at
the correct TOE-IN position. Position clamp
bolts to their original position and tighten to specifications. Make sure the toe setting does not
change during clamp tightening.
NOTE: Toe setting will change during tightening, Make sure to verify reading after tightening.
5. Verify the right toe setting and a straight steering wheel. 6. Road test the vehicle.

Ignition Cable: Description and Operation
Spark plug cables are sometimes referred to as secondary ignition wires, or secondary ignition
cables. Plug cables are used only on the 5.7L V-8 engine.
The spark plug cables transfer electrical current from the ignition coil(s) and/or distributor, to
individual spark plugs at each cylinder. The resistive spark plug cables are of nonmetallic
construction. The cables provide suppression of radio frequency emissions from the ignition
system.

REMOVAL
Spark plug cables on the 5.7L engine are paired on cylinders 1/6, 2/3, 4/7 and 5/8. Before
removing or disconnecting any spark plug cables, note their original position. Remove cables
one-at-a-time. To prevent ignition crossfire, spark plug cables MUST be placed in cable tray
(routing loom) into their original position. The cable retention clips must also be securely locked.
Before installing spark plug cables to either the spark plugs or coils, apply dielectric grease to
inside of boots.
If cable tray removal is necessary, release the 4 tray-to-manifold retention clips.
INSTALLATION
Install cables into the proper engine cylinder firing order sequence. Refer to Specifications. When
replacing the spark plug and coil cables, route the cables correctly and secure them in the proper
retainers. Failure to route the cables properly may cause the radio to reproduce ignition noise. It
could also cause cross-ignition of the plugs, or, may short-circuit the cables to ground. When
installing new cables, make sure a positive connection is made. A snap should be felt when a good
connection is made.

DIAGNOSIS AND TESTING
ACCESSORY DRIVE BELT
VISUAL DIAGNOSIS
NOTE: 5.9L Diesel Engine - If a belt is broken or frayed, inspect engine speed sensor (located near
the crankshaft damper) for damage.
When diagnosing serpentine accessory drive belts, small cracks that run across the ribbed surface
of the belt from rib to rib, are considered normal. These are not a reason to replace the belt.
However, cracks running along a rib (not across) are not normal. Any belt with cracks running
along a rib must be replaced. Also replace the belt if it has excessive wear, frayed cords or severe
glazing.
Refer to ACCESSORY DRIVE BELT DIAGNOSIS CHART for further belt diagnosis.
NOISE DIAGNOSIS
Noises generated by the accessory drive belt are most noticeable at idle. Before replacing a belt to
resolve a noise condition, inspect all of the accessory drive pulleys for alignment, glazing, or
excessive end play.

SEPTEMBER 01, 2005, WHICH SHOULD BE REMOVED FROM YOUR FILES. THIS IS A
COMPLETE REVISION AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS.
SUBJECT: RFE Transmission Filters - Delayed Engagement And Related Transmission DTC'S
OVERVIEW: This bulletin involves verifying the build date of the transmission, and if necessary, the
replacement of both the cooler return and sump filters in the transmission.
MODELS:
2005 - 2006 (DR) Ram Truck
2005 - 2006 (HB) Durango
2005 - 2006 (KJ) Liberty / Cherokee
2005 - 2006 (ND) Dakota
2005 - 2006 (WK / WH) Grand Cherokee
2006 (XK) Commander
NOTE:
This bulletin applies to vehicles equipped with the a 45RFE or a 545RFE automatic transmission
(sales code DG4 or DGQ respectively) having a specific transmission build date code (see the
below DIAGNOSIS section for further details).
SYMPTOM/CONDITION:
The customer may experience an initial delayed shift engagement following an extended off (not
running) period of time, generally after being parked overnight. The initial shift engagement may
feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine
start.
The customer may also experience a MIL illumination. Investigation may determine that the MIL is
due to one or more of the following Diagnostic Trouble Codes (DIG's):
P0868 - Line Pressure Low. This DIG will be the most frequently occurring DTC for the delayed
shift condition.
P0944 - Loss Of Hydraulic Pump Prime.
P0731 - Gear Ratio Error In 1st.
P0736 - Gear Ratio Error In Reverse.
P0841 - LR Pressure Switch Rationality.
P0876 - UD Pressure Switch Rationality.
The delayed engagement and MIL condition (DTC's) may be caused by a suspect transmission
cooler return filter with a part number of 04799662AB. A suspect 04799662AB cooler return filter
may cause the transmission sump filter to split at its plastic-to-metal crimp. If the transmission
sump filter becomes split at the crimp, then one or more of the above DTC's may also occur.
DIAGNOSIS:
1. Turn the ignition to the "OFF" position.
2. Raise the vehicle on a suitable lift.

Set > Page 1195
3. Inspect for the transmission build date (Julian date) (Fig. 1). The transmission build date can be
determined by inspection of the 20 digit transmission identification number
(DDDYxxxxxPpartnumber). The transmission identification number is stamped on the left side
(driver side) of the transmission oil pan flange. The first four (4) digits of the transmission
identification number are the transmission build date, in Julian date format. An example of a
transmission identification number would be 101510492P52119684AA. The first three digits ( 101 )
of the identification number equal the day of the year, in this case 101 equals April 11. The fourth
digit ( 5 ) of the identification number equals the calendar year, in this case 5 equals 2005. So 1015
equals April 11, 2005.
4. Determine if the vehicle's transmission was built on or between one of the two sets of Julian date
build ranges listed below:
a. Julian date 0425 (February 11, 2005) to Julian date 0455 (February 15, 2005). 0425 to 0455.
b. Julian date 1015 (April 11, 2005) to Julian date 2345 (August 22, 2005). 1015 to 2345.
5. If the vehicle has the above condition, and if the transmission Julian build date is on or between
the range of dates listed above, perform the Repair Procedure.
NOTE:
Both the transmission cooler return filter and the transmission sump filter MUST BE replaced at the
same time.
PARTS REQUIRED:
NOTE:
DO NOT use a replacement cooler return filter with a part number of 04799662AB. This filter is
suspect of causing the above condition. The cooler

return filter part number is stenciled on the side of the filter's metal case.
SPECIAL TOOLS/EQUIPMENT REQUIRED:
REPAIR PROCEDURE:
NOTE:
All cooler return filters with the "AB" suffix (04799662AB) are suspect. The above condition may be
corrected by replacing a suspect "AB" filter with a new cooler return filter whose part number is
04799662 (with no suffix or with a suffix that is other than the "AB" level), and a new sump filter.
NOTE:
BOTH the sump oil filter and the cooler return filter MUST BE replaced in the transmission at the
same time. Do not replace one filter without also replacing the other filter.
NOTE:
A replacement 04799662 cooler return filter may come packaged with a separate threaded adapter
stud. The threaded adapter stud is used to attach the cooler return filter to the transmission.
Inspect the stud and note end without threads. Install the stud end without the threads into the
cooler return filter and tighten the stud-to4ilter connection to 18.6 Nm (165 in.lbs.). Once the
threaded adapter stud has been installed to the cooler return filter, install the assembled cooler
return filter to the transmission and tighten the filter to 14.1 Nm (125 in.lbs.)
Use the procedures outlined in TechCONNECT(R) (Service Information Tab / 21 - Transmission
Transaxle / Automatic - 45RFE 545RFE / Fluid / Standard Procedure / Fluid and Filter
Replacement) to replace BOTH the transmission cooler return filter and the transmission sump oil
filter.
NOTE:
Always install the sump filter seal to the bottom of the transmission oil pump first, then install the
sump filter to the oil pump and previously installed seal. DO NOT install the sump filter seal to the
sump filter and then attempt to install both to the oil pump.

NOTE:
This bulletin applies to vehicles equipped with a 45RFE or a 545RFE automatic transmission (sales
code DG4 or DGQ respectively).
DISCUSSION:
The customer may experience an initial delayed shift engagement following an extended off (not
running) period of time, generally after being parked overnight. The initial shift engagement may
feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine
start.
The customer may not have experienced the delayed shift engagement until after the transmission
has been serviced, where the cooler return filter was replaced during the service and/or repair.
The condition is not detrimental to the transmission but may cause concern with the customer.
The above condition may be caused by a suspect cooler return filter a part number of
04799662AB. This "AB" suffix / level filter may allow transmission fluid to drain back out of the
torque converter. The drain back condition may occur over a period time when the engine (and
transmission) are not running. With less fluid in the torque converter a delay in gear engagement
may occur at engine start up while the torque converter fills to its proper fluid level.
All 04799662AB cooler return filters with the "AB" suffix are suspect. The above condition may be
corrected by replacing a suspect "AB" filter with a new cooler return filter whose part number is
04799662 (with no suffix or with a suffix that is other than the "AB" level).
NOTE:
The cooler return filter, p/n 04799662, will not be available until September 09, 2005. The filter part
number is stenciled on the side of the filter case.

SUBJECT: RFE Transmission Filters - Delayed Engagement And Related Transmission DTC'S
OVERVIEW: This bulletin involves verifying the build date of the transmission, and if necessary, the
replacement of both the cooler return and sump filters in the transmission.
MODELS:
2005 - 2006 (DR) Ram Truck
2005 - 2006 (HB) Durango
2005 - 2006 (KJ) Liberty / Cherokee
2005 - 2006 (ND) Dakota
2005 - 2006 (WK / WH) Grand Cherokee
2006 (XK) Commander
NOTE:
This bulletin applies to vehicles equipped with the a 45RFE or a 545RFE automatic transmission
(sales code DG4 or DGQ respectively) having a specific transmission build date code (see the
below DIAGNOSIS section for further details).
SYMPTOM/CONDITION:
The customer may experience an initial delayed shift engagement following an extended off (not
running) period of time, generally after being parked overnight. The initial shift engagement may
feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine
start.
The customer may also experience a MIL illumination. Investigation may determine that the MIL is
due to one or more of the following Diagnostic Trouble Codes (DIG's):
P0868 - Line Pressure Low. This DIG will be the most frequently occurring DTC for the delayed
shift condition.
P0944 - Loss Of Hydraulic Pump Prime.
P0731 - Gear Ratio Error In 1st.
P0736 - Gear Ratio Error In Reverse.
P0841 - LR Pressure Switch Rationality.
P0876 - UD Pressure Switch Rationality.
The delayed engagement and MIL condition (DTC's) may be caused by a suspect transmission
cooler return filter with a part number of 04799662AB. A suspect 04799662AB cooler return filter
may cause the transmission sump filter to split at its plastic-to-metal crimp. If the transmission
sump filter becomes split at the crimp, then one or more of the above DTC's may also occur.
DIAGNOSIS:
1. Turn the ignition to the "OFF" position.
2. Raise the vehicle on a suitable lift.

Engagement/Related DTC's Set > Page 1208
3. Inspect for the transmission build date (Julian date) (Fig. 1). The transmission build date can be
determined by inspection of the 20 digit transmission identification number
(DDDYxxxxxPpartnumber). The transmission identification number is stamped on the left side
(driver side) of the transmission oil pan flange. The first four (4) digits of the transmission
identification number are the transmission build date, in Julian date format. An example of a
transmission identification number would be 101510492P52119684AA. The first three digits ( 101 )
of the identification number equal the day of the year, in this case 101 equals April 11. The fourth
digit ( 5 ) of the identification number equals the calendar year, in this case 5 equals 2005. So 1015
equals April 11, 2005.
4. Determine if the vehicle's transmission was built on or between one of the two sets of Julian date
build ranges listed below:
a. Julian date 0425 (February 11, 2005) to Julian date 0455 (February 15, 2005). 0425 to 0455.
b. Julian date 1015 (April 11, 2005) to Julian date 2345 (August 22, 2005). 1015 to 2345.
5. If the vehicle has the above condition, and if the transmission Julian build date is on or between
the range of dates listed above, perform the Repair Procedure.
NOTE:
Both the transmission cooler return filter and the transmission sump filter MUST BE replaced at the
same time.
PARTS REQUIRED:
NOTE:
DO NOT use a replacement cooler return filter with a part number of 04799662AB. This filter is
suspect of causing the above condition. The cooler

WARNING:
- THE A/C SYSTEM CONTAINS REFRIGERANT UNDER HIGH PRESSURE. REPAIRS SHOULD
ONLY BE PERFORMED BY QUALIFIED SERVICE PERSONNEL. SEVERE PERSONAL INJURY
OR DEATH MAY RESULT FROM IMPROPER SERVICE PROCEDURES.
- VOID BREATHING THE REFRIGERANT AND REFRIGERANT OIL VAPOR OR MIST.
EXPOSURE MAY IRRITATE THE EYES, NOSE, AND/OR THROAT. WEAR EYE PROTECTION
WHEN SERVICING THE A/C REFRIGERANT SYSTEM. SERIOUS EYE INJURY CAN RESULT
FROM DIRECT CONTACT WITH THE REFRIGERANT. IF EYE CONTACT OCCURS, SEEK
MEDICAL ATTENTION IMMEDIATELY.
- DO NOT EXPOSE THE REFRIGERANT TO OPEN FLAME. POISONOUS GAS IS CREATED
WHEN REFRIGERANT IS BURNED. AN ELECTRONIC LEAK DETECTOR IS RECOMMENDED.
SEVERE PERSONAL INJURY OR DEATH MAY RESULT FROM IMPROPER SERVICE
PROCEDURES.
- IF ACCIDENTAL SYSTEM DISCHARGE OCCURS, VENTILATE THE WORK AREA BEFORE
RESUMING SERVICE. LARGE AMOUNTS OF REFRIGERANT RELEASED IN A CLOSED
WORK AREA WILL DISPLACE THE OXYGEN AND CAUSE SUFFOCATION AND DEATH.
- THE EVAPORATION RATE OF R-134A REFRIGERANT AT AVERAGE TEMPERATURE AND
ALTITUDE IS EXTREMELY HIGH. AS A RESULT, ANYTHING THAT COMES IN CONTACT
WITH THE REFRIGERANT WILL FREEZE. ALWAYS PROTECT THE SKIN OR DELICATE
OBJECTS FROM DIRECT CONTACT WITH THE REFRIGERANT.
- THE R-134A SERVICE EQUIPMENT OR THE VEHICLE REFRIGERANT SYSTEM SHOULD
NOT BE PRESSURE TESTED OR LEAK TESTED WITH COMPRESSED AIR. SOME MIXTURES
OF AIR AND R-134A HAVE BEEN SHOWN TO BE COMBUSTIBLE AT ELEVATED
PRESSURES. THESE MIXTURES ARE POTENTIALLY DANGEROUS, AND MAY RESULT IN
FIRE OR EXPLOSION CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
- THE ENGINE COOLING SYSTEM IS DESIGNED TO DEVELOP INTERNAL PRESSURES OF
97 TO 123 KILOPASCALS (14 TO 18 POUNDS PER SQUARE INCH). DO NOT REMOVE OR
LOOSEN THE COOLANT PRESSURE CAP, CYLINDER BLOCK DRAIN PLUGS, RADIATOR
DRAIN, RADIATOR HOSES, HEATER HOSES, OR HOSE CLAMPS WHILE THE ENGINE
COOLING SYSTEM IS HOT AND UNDER PRESSURE. ALLOW THE VEHICLE TO COOL FOR A
MINIMUM OF 15 MINUTES BEFORE OPENING THE COOLING SYSTEM FOR SERVICE.
FAILURE TO OBSERVE THIS WARNING CAN RESULT IN SERIOUS BURNS FROM THE
HEATED ENGINE COOLANT.
CAUTION:
- Never add R-12 to a refrigerant system designed to use R-134a. Do not use R-12 equipment or
parts on a R-134a A/C system. These refrigerants are not compatible and damage to the A/C
system will result.
- Never use R-12 refrigerant oil in a A/C system designed to use R-134a refrigerant oil. These
refrigerant oils are not compatible and damage to the A/C system will result.
- The use of A/C system sealers may result in damage to A/C refrigerant
recovery/evacuation/recharging equipment and/or A/C system. Many federal, state/provincial and
local regulations prohibit the recharge of A/C systems with known leaks. DaimlerChrysler
recommends the detection of A/C system leaks through the use of approved leak detectors and
fluorescent leak detection dyes. Vehicles found with A/C system sealers should be treated as
contaminated and replacement of the entire A/C refrigerant system is recommended. A/C systems
found to be contaminated with A/C system sealers, A/C stop-leak products or seal conditioners
voids the warranty for the A/C system.
- Recover the refrigerant before opening any fitting or connection. Open the fittings with caution,
even after the system has been discharged. Never open or loosen a connection before recovering
the refrigerant.
- If equipped, do not remove the secondary retention clip from any spring-lock coupler connection
while the refrigerant system is under pressure. Recover the refrigerant before removing the
secondary retention clip. Open the fittings with caution, even after the system has been discharged.
Never open or loosen a connection before recovering the refrigerant.
- The internal parts of the A/C system will remain stable as long as moisture-free refrigerant and
refrigerant oil is used. Abnormal amounts of dirt, moisture or air can upset the chemical stability.
This may cause operational troubles or even serious damage if present in more than very small
quantities. Before disconnecting a component, clean the outside of the fittings thoroughly to
prevent contamination from entering the refrigerant system. Keep service tools and the work area
clean. Do not open the refrigerant system or uncap a replacement component until you are ready
to service the system. Immediately after disconnecting a component from the refrigerant system,
seal the open fittings with a cap or plug. This will prevent contamination from entering the A/C
system.
- Refrigerant oil will absorb moisture from the atmosphere if left uncapped. Do not open a container
of refrigerant oil until you are ready to use it. Replace the cap on the oil container immediately after
using. Store refrigerant oil only in a clean, airtight, and moisture-free container.
- Do not overcharge the refrigerant system. Overcharging will cause excessive compressor head
pressure and can cause compressor noise and A/C system failure.

The spring-lock refrigerant line couplers require special disconnect tools for disengaging the two
coupler halves.
The spring-lock type refrigerant line coupler is held together by a garter spring (6) inside a circular
cage (7) on the male half of the fitting (1). When the two coupler halves are connected, the flared
end of the female fitting (2) slips behind the garter spring inside the cage on the male fitting. The
garter spring and cage prevent the flared end of the female fitting from pulling out of the cage.
Some applications use a connection indicator ring (4) to help indicate when the two coupler halves
are fully connected.
Two O-rings (8) are used to seal the coupler connections. These O-rings are compatible with
R-134a refrigerant and must be replaced with O-rings made of the same material.
A secondary retaining clip (3) is installed over the connected coupler (5) for added protection.

Hose/Line HVAC: Description and Operation Plumbing
The A/C refrigerant lines and hoses are used to carry the refrigerant between the various A/C
system components. The refrigerant lines and hoses for the R-134a system on this vehicle consist
of a barrier-hose design with a nylon tube sandwiched between rubber layers. The nylon tube helps
to contain the R-134a refrigerant, which has a smaller molecular structure than R-12 refrigerant.
The ends of the refrigerant lines are made from lightweight aluminum or steel, and commonly use
braze-less fittings.
Any kinks or sharp bends in the refrigerant lines and hoses will reduce the capacity of the entire
A/C system and can reduce the flow of refrigerant in the system. The radius of all bends in the
flexible hose refrigerant lines should be at least ten times the diameter of the hose and the
refrigerant lines should be routed so they are at least 80 millimeters (3 inches) away from the
exhaust manifold(s) and exhaust pipe(s).
High pressures are produced in the refrigerant system when the A/C compressor is operating.
Extreme care must be exercised to make sure that each of the refrigerant system connections is
pressure-tight and leak free. It is a good practice to inspect all flexible hose refrigerant lines at least
once a year to make sure they are in good condition and properly routed.
The refrigerant lines and hoses are coupled to other A/C system components with block-type
fittings. An O-ring seal, or a flat steel gasket with an integral O-ring (dual plane seal), is used to
mate the refrigerant line fittings with A/C system components to ensure the integrity of the
refrigerant system.
The refrigerant lines and hoses cannot be repaired and, if faulty or damaged, they must be
replaced.

Hose/Line HVAC: Description and Operation Line-A/C Discharge
The A/C discharge line is the refrigerant line that goes from the A/C compressor to the A/C
condenser and has an integral fitting for the A/C pressure transducer.
The A/C discharge line for the 5.9L Diesel engine is serviced as an assembly with the suction line.
The A/C discharge line for the 8.3L engine is secured to the top of fan shroud by two retainers.
CAUTION: Use only O-ring seals specified for the vehicle. Failure to use correct O-ring seal will
cause the refrigerant system connection to leak.
The A/C discharge line has no serviceable parts except the rubber O-ring seals. The O-ring seals
used on the connections are made from a special type of rubber not affected by R-134a refrigerant.
The O-ring seals must be replaced whenever the A/C discharge line is removed and installed.
If the A/C discharge line is found to be leaking or is damaged, it must be replaced.

evaporator. The liquid line for this model consist of two separate lines that connect to each other
using a spring-lock type refrigerant line coupler. The liquid lines are made from light-weight
aluminum, and use braze-less fittings.
The front half of the liquid line includes the high-side service port and the rear half of the liquid line
contains the fixed orifice tube.
CAUTION: Use only O-ring seals specified for the vehicle. Failure to use the correct O-ring seal will
cause the refrigerant system connections to leak.

Hose/Line HVAC: Testing and Inspection
REFRIGERANT SYSTEM LEAKS
WARNING:
- R-134A SERVICE EQUIPMENT OR VEHICLE A/C SYSTEM SHOULD NOT BE PRESSURE
TESTED OR LEAK TESTED WITH COMPRESSED AIR. MIXTURE OF AIR AND R-134A CAN BE
COMBUSTIBLE AT ELEVATED PRESSURES. THESE MIXTURES ARE POTENTIALLY
DANGEROUS AND MAY RESULT IN FIRE OR EXPLOSION CAUSING PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH.
- AVOID BREATHING A/C REFRIGERANT AND LUBRICANT VAPOR OR MIST. EXPOSURE
MAY IRRITATE EYES, NOSE AND THROAT. USE ONLY APPROVED SERVICE EQUIPMENT
MEETING SAE REQUIREMENTS TO DISCHARGE R-134A SYSTEM. IF ACCIDENTAL SYSTEM
DISCHARGE OCCURS, VENTILATE WORK AREA BEFORE RESUMING SERVICE.
If the A/C system is not cooling properly, determine if the refrigerant system is fully charged with
R-134a. This is accomplished by performing a system Charge Level-Check or Fill. If while
performing this test A/C liquid line pressure is less than 345 kPa (50 psi) proceed to System Empty
procedure. If liquid line pressure is greater than 345 kPa (50 psi) proceed to System Low
procedure. If the refrigerant system is empty or low in refrigerant charge, a leak at any line fitting or
component seal is likely. A review of the fittings, lines and components for oily residue is an
indication of the leak location. To detect a leak in the refrigerant system, perform one of the
following procedures as indicated by the symptoms.
SYSTEM EMPTY
1. Evacuate the refrigerant system to the lowest degree of vacuum possible (approximately 28 in
Hg.). Determine if the system holds a vacuum for
15 minutes. If vacuum is held, a leak is probably not present. If system will not maintain vacuum
level, proceed to Step 2.
2. Prepare a 0.284 Kg. (10 oz.) refrigerant charge to be injected into the refrigerant system. 3.
Connect and dispense 0.284 Kg. (10 oz.) of refrigerant into the evacuated refrigerant system. 4.
Proceed to Step 2 of System Low procedure.
SYSTEM LOW
1. Determine if there is any R-134a refrigerant in the system. 2. Position the vehicle in a wind free
work area. This will aid in detecting small leaks. 3. Bring the refrigerant system up to operating
temperature and pressure. This is done by allowing the engine to run for five minutes with the A/C
system set to the following: Transmission in Park or Neutral with parking brake set
- Engine idling
- Mode control set to the outside air position
- Blower control set to the high speed position
- A/C set to the ON position
- All windows open
CAUTION: A leak detector only designed for R-12 refrigerant will not detect leaks in a R-134a
refrigerant system.
4. Shut the vehicle Off and wait 2-7 minutes. Then use an electronic leak detector that is designed
to detect R-134a refrigerant and search for leaks.
Fittings, lines or components that appear to be oily usually indicate a refrigerant leak. To inspect
the A/C evaporator for leaks, insert the leak detector probe into the drain tube opening or an air
outlet. A dye for R-134a is available to aid in leak detection. Use only DaimlerChrysler approved
refrigerant dye.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all

FLUID DIAGNOSIS AND TESTING
BRAKE FLUID CONTAMINATION
Indications of fluid contamination are swollen or deteriorated rubber parts.
Swollen rubber parts indicate the presence of petroleum in the brake fluid.
To test for contamination, put a small amount of drained brake fluid in clear glass jar. If fluid
separates into layers, there is mineral oil or other fluid contamination of the brake fluid.
If brake fluid is contaminated, drain and thoroughly flush system. Replace master cylinder,
proportioning valve, caliper seals, wheel cylinder seals, Antilock Brakes hydraulic unit and all
hydraulic fluid hoses.

DESCRIPTION
ENGINE COOLANT
WARNING: ANTIFREEZE IS AN ETHYLENE GLYCOL BASE COOLANT AND IS HARMFUL IF
SWALLOWED OR INHALED. IF SWALLOWED, DRINK TWO GLASSES OF WATER AND
INDUCE VOMITING. IF INHALED, MOVE TO FRESH AIR AREA. SEEK MEDICAL ATTENTION
IMMEDIATELY. DO NOT STORE IN OPEN OR UNMARKED CONTAINERS. WASH SKIN AND
CLOTHING THOROUGHLY AFTER COMING IN CONTACT WITH ETHYLENE GLYCOL. KEEP
OUT OF REACH OF CHILDREN. DISPOSE OF GLYCOL BASE COOLANT PROPERLY,
CONTACT YOUR DEALER OR GOVERNMENT AGENCY FOR LOCATION OF COLLECTION
CENTER IN YOUR AREA. DO NOT OPEN A COOLING SYSTEM WHEN THE ENGINE IS AT
OPERATING TEMPERATURE OR HOT UNDER PRESSURE, PERSONAL INJURY CAN
RESULT. AVOID RADIATOR COOLING FAN WHEN ENGINE COMPARTMENT RELATED
SERVICE IS PERFORMED, PERSONAL INJURY CAN RESULT.
ETHYLENE-GLYCOL MIXTURES
CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can
cause problems associated with 100 percent ethylene-glycol.
The use of aluminum cylinder blocks, cylinder heads and water pumps requires special corrosion
protection. Only Mopar(R) Antifreeze/Coolant, 5 year/100,000 Mile Formula (ethylene-glycol base
coolant with corrosion inhibitors called HOAT, for Hybrid Additive Technology) is recommended.
This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water
to obtain a freeze point of -37°C (-35°F).
The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle
operating conditions. The antifreeze concentration must always be a minimum of 44 percent,
year-round in all climates. If percentage is lower than 44 percent, engine parts may be eroded by
cavitation, and cooling system components may be severely damaged by corrosion. Maximum
protection against freezing is provided with a 68% antifreeze concentration, which prevents
freezing down to -67.7° C (-90° F). A higher percentage will freeze at a warmer temperature. Also,
a higher percentage of antifreeze can cause the engine to overheat because the specific heat of
antifreeze is lower than that of water.
Use of 100 percent ethylene-glycol will cause formation of additive deposits in the system, as the
corrosion inhibitive additives in ethylene-glycol require the presence of water to dissolve. The
deposits act as insulation, causing temperatures to rise to as high as 149°C (300°F). This
temperature is hot enough to melt plastic and soften solder. The increased temperature can result
in engine detonation. In addition, 100 percent ethylene-glycol freezes at 22°C (8°F).
PROPYLENE-GLYCOL MIXTURES
It's overall effective temperature range is smaller than that of ethylene-glycol. The freeze point of
50/50 propylene-glycol and water is -32°C (-26°F). 5°C higher than ethylene-glycol's freeze point.
The boiling point (protection against summer boil-over) of propylene-glycol is 125°C (257°F) at 96.5
kPa (14 psi), compared to 128°C (263°F) for ethylene-glycol. Use of propylene-glycol can result in
boil-over or freeze-up on a cooling system designed for ethylene-glycol. Propylene glycol also has
poorer heat transfer characteristics than ethylene glycol. This can increase cylinder head
temperatures under certain conditions.
Propylene-glycol-ethylene-glycol Mixtures can cause the destabilization of various corrosion
inhibitors, causing damage to the various cooling system components. Also, once ethylene-glycol
and propylene-glycol based coolants are mixed in the vehicle, conventional methods of determining
freeze point will not be accurate. Both the refractive index and specific gravity differ between
ethylene glycol and propylene glycol.
OPERATION
Coolant flows through the engine block absorbing the heat from the engine, then flows to the
radiator where the cooling fins in the radiator transfers the heat from the coolant to the atmosphere.
During cold weather the ethylene-glycol or propylene-glycol coolant prevents water present in the
cooling system from freezing within temperatures indicated by mixture ratio of coolant to water.

HOAT COOLANT
WARNING: ANTIFREEZE IS AN ETHYLENE-GLYCOL BASE COOLANT AND IS HARMFUL IF
SWALLOWED OR INHALED. IF SWALLOWED, DRINK TWO GLASSES OF WATER AND
INDUCE VOMITING. IF INHALED, MOVE TO FRESH AIR AREA. SEEK MEDICAL ATTENTION
IMMEDIATELY. DO NOT STORE IN OPEN OR UNMARKED CONTAINERS. WASH SKIN AND
CLOTHING THOROUGHLY AFTER COMING IN CONTACT WITH ETHYLENE-GLYCOL. KEEP

CENTER IN YOUR AREA. DO NOT OPEN A COOLING SYSTEM WHEN THE ENGINE IS AT
OPERATING TEMPERATURE OR HOT UNDER PRESSURE, PERSONAL INJURY CAN
RESULT. AVOID RADIATOR COOLING FAN WHEN ENGINE COMPARTMENT RELATED
SERVICE IS PERFORMED, PERSONAL INJURY CAN RESULT.
CAUTION: Use of Propylene-Glycol based coolants is not recommended, as they provide less
freeze protection and less corrosion protection.
The cooling system is designed around the coolant. The coolant must accept heat from engine
metal, in the cylinder head area near the exhaust valves and engine block. Then coolant carries the
heat to the radiator where the tube/ fin radiator can transfer the heat to the air.
The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion
protection. Mopar(R) Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the
equivalent ethylene-glycol base coolant with organic corrosion inhibitors (called HOAT, for Hybrid
Organic Additive Technology) is recommended. This coolant offers the best engine cooling without
corrosion when mixed with 50% ethylene-glycol and 50% distilled water to obtain a freeze point of
-37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh
properly mixed coolant solution.
CAUTION: Mopar(R) Antifreeze/Coolant, 5 Year/10O,000 Mile Formula (MS-9769) may not be
mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other
HOAT), may result in engine damage that may not be covered under the new vehicle warranty, and
decreased corrosion protection.
COOLANT PERFORMANCE
The required ethylene-glycol (antifreeze) and water mixture depends upon climate and vehicle
operating conditions. The coolant performance of various mixtures follows:
Pure Water - Water can absorb more heat than a mixture of water and ethylene-glycol. This is for
purpose of heat transfer only. Water also freezes at a higher temperature and allows corrosion.
100 percent Ethylene-Glycol - The corrosion inhibiting additives in ethylene-glycol need the
presence of water to dissolve. Without water, additives form deposits in system. These act as
insulation causing temperature to rise to as high as 149°C (300°F). This temperature is hot enough
to melt plastic and soften solder. The increased temperature can result in engine detonation. In
addition, 100 percent ethylene-glycol freezes at -22°C (-8°F).
50/50 Ethylene-Glycol and Water - Is the recommended mixture, it provides protection against
freezing to -37°C (-34°F). The antifreeze concentration must always be a minimum of 44 percent,
year-round in all climates. If percentage is lower, engine parts may be eroded by cavitation.
Maximum protection against freezing is provided with a 68 percent antifreeze concentration, which
prevents freezing down to --67.7°C (--90°F). A higher percentage will freeze at a warmer
temperature. Also, a higher percentage of antifreeze can cause the engine to overheat because
specific heat of antifreeze is lower than that of water.
CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can
cause problems associated with 100 percent ethylene-glycol.
COOLANT SELECTION AND ADDITIVES
The use of aluminum cylinder blocks, cylinder heads and water pumps requires special corrosion
protection. Only Mopar(R) Antifreeze/Coolant, 5 Year/100,000 Mile Formula (glycol base coolant
with corrosion inhibitors called HOAT, for Hybrid Organic Additive Technology) is recommended.
This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water
to obtain to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain,
flush, and replace with fresh properly mixed coolant solution.
CAUTION: Do not use coolant additives that are claimed to improve engine cooling.
OPERATION
Coolant flows through the engine block absorbing the heat from the engine, then flows to the
radiator where the cooling fins in the radiator transfers the heat from the coolant to the atmosphere.
During cold weather the ethylene-glycol or propylene-glycol coolant prevents water present in the
cooling system from freezing within temperatures indicated by mixture ratio of coolant to water.

Coolant: Testing and Inspection
DIAGNOSIS AND TESTING
COOLANT CONCENTRATION TESTING
Coolant concentration should be checked when any additional coolant was added to system or
after a coolant drain, flush and refill. The coolant mixture offers optimum engine cooling and
protection against corrosion when mixed to a freeze point of -37°C (-34°F) to -46°C (-50°F). The
use of a hydrometer or a refractometer can be used to test coolant concentration.
A hydrometer will test the amount of glycol in a mixture by measuring the specific gravity of the
mixture. The higher the concentration of ethylene glycol, the larger the number of balls that will
float, and higher the freeze protection (up to a maximum of 60% by volume glycol).
A refractometer Tool 8286 will test the amount of glycol in a coolant mixture by measuring the
amount a beam of light bends as it passes through the fluid.
Some coolant manufactures use other types of glycols into their coolant formulations. Propylene
glycol is the most common new coolant. However, propylene glycol based coolants do not provide
the same freezing protection and corrosion protection and is not recommended.
CAUTION: Do not mix types of coolant - corrosion protection will be severely reduced.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

Transmission (CVT) and WG vehicles equipped with a diesel engine (sales code ENF) and a
W5J400 or NAG1 transmission (sales code DGJ).
DISCUSSION:
ATF+4(R) - (Type 9602) is being used as factory fill for Chrysler Group automatic transmissions.
ATF+4(R) is recommended for all vehicles equipped with Chrysler Group automatic transmissions
EXCEPT FOR THOSE LISTED IN THE NOTE ABOVE.
NOTE:
ATF+4(R) must always be used in vehicles that were originally filled with ATF+4(R). DO NOT USE
ANY OTHER FLUID.
NOTE:
ATF+4(R) is backward compatible with ATF+3, ATF+2, and ATF+. Additionally, ATF+4(R) can be
used to top off vehicles that used ATF+3, ATF+2, or ATF+.
NOTE:
If ATF+4® is used to service models originally filled with ATF+3, ATF+2, and ATF+ the fluid
maintenance schedules listed for that model does not change. The service interval currently in
effect for a given model should continue to be followed. Refer to the Service or Owners manual for
maintenance schedule directions.
In general terms, If ATF+, ATF+2 or ATF+3 was the recommended fluid, it is now recommended to
use ATF+4®
BENEFITS
^ Better anti-wear properties
^ Improved rust/corrosion prevention
^ Controls oxidation
^ Eliminates deposits
^ Controls friction
^ Retains anti-foaming properties
^ Superior properties for low temperature operation
FLUID COLOR
Mopar ATF+4(R) has exceptional durability. However, the red dye used in ATF+4(R) is not
permanent; as the fluid ages it may become darker or appear brown in color. ATF+4(R) also has a
unique odor that may change with age. With ATF+4(R) fluid, color and odor are no longer
indicators of fluid condition and do not necessarily support a fluid change.

NOTE:
This Service Bulletin DOES NOT apply to AW-4 transmissions, Sprinter transmissions, Crossfire
transmissions, MK/PM vehicles equipped with Continuously Variable Transmission (CVT) and WG
vehicles equipped with a diesel engine (sales code ENF) and a W5J400 or NAG1 transmission
(sales code DGJ).
DISCUSSION:
ATF+4(R) - (Type 9602) is being used as factory fill for Chrysler Group automatic transmissions.
ATF+4(R) is recommended for all vehicles equipped with Chrysler Group automatic transmissions
EXCEPT FOR THOSE NOTED ABOVE.
NOTE:
ATF+4(R) must always be used in vehicles that were originally filled with ATF+4(R). DO NOT USE
ANY OTHER FLUID.
NOTE:
ATF+4(R) is backward compatible with ATF+3, ATF+2, and ATF+. Additionally, ATF+4 can be
used to top off vehicles that used ATF+3, ATF+2, or ATF+.
NOTE:
If ATF+4(R) is used to service models originally filled with ATF+3, ATF+2, and ATF+ the fluid
maintenance schedules listed for that model does not change. The service interval currently in
effect for a given model should continue to be followed. Refer to the Service or Owners manual for
maintenance schedule directions.
In general terms, If ATF+, ATF+2 or ATF+3 was the recommended fluid, it is now recommended to
use ATF+4.

BENEFITS
^ Better anti-wear properties
^ Improved rust/corrosion prevention
^ Controls oxidation
^ Eliminates deposits
^ Controls friction
^ Retains anti-foaming properties
^ Superior properties for low temperature operation
FLUID COLOR
Mopar ATF+4(R) has exceptional durability. However, the red dye used in ATF+4(R) is not
permanent; as the fluid ages it may become darker or appear brown in color. ATF+4(R) also has a
unique odor that may change with age. With ATF+4(R) fluid, color and odor are no longer
indicators of fluid condition and do not necessarily support a fluid change.

Fluid - A/T: Testing and Inspection
FLUID
DIAGNOSIS AND TESTING EFFECTS OF INCORRECT FLUID LEVEL
A low fluid level allows the pump to take in air along with the fluid. Air in the fluid will cause fluid
pressures to be low and develop slower than normal. If the transmission is overfilled, the gears
churn the fluid into foam. This aerates the fluid and causing the same conditions occurring with a
low level. In either case, air bubbles cause fluid overheating, oxidation, and varnish buildup which
interferes with valve and clutch operation. Foaming also causes fluid expansion which can result in
fluid overflow from the transmission vent or fill tube. Fluid overflow can easily be mistaken for a
leak if inspection is not careful.
CAUSES OF BURNT FLUID
Burnt, discolored fluid is a result of overheating which has three primary causes. 1. Internal clutch
slippage, usually caused by low line pressure, inadequate clutch apply pressure, or clutch seal
failure. 2. A result of restricted fluid flow through the main and/or auxiliary cooler. This condition is
usually the result of a faulty or improperly installed
drainback valve, a damaged oil cooler, or severe restrictions in the coolers and lines caused by
debris or kinked lines.
3. Heavy duty operation with a vehicle not properly equipped for this type of operation. Trailer
towing or similar high load operation will overheat
the transmission fluid if the vehicle is improperly equipped. Such vehicles should have an auxiliary
transmission fluid cooler, a heavy duty cooling system, and the engine/axle ratio combination
needed to handle heavy loads.
FLUID CONTAMINATION
Transmission fluid contamination is generally a result of: ^
adding incorrect fluid
^ failure to clean dipstick and fill tube when checking level
^ engine coolant entering the fluid . internal failure that generates debris
^ overheat that generates sludge (fluid breakdown)
^ failure to replace contaminated converter after repair
The use of non-recommended fluids can result in transmission failure. The usual results are erratic
shifts, slippage, abnormal wear and eventual failure due to fluid breakdown and sludge formation.
Avoid this condition by using recommended fluids only.
The dipstick cap and fill tube should be wiped clean before checking fluid level. Dirt, grease and
other foreign material on the cap and tube could fall into the tube if not removed beforehand. Take
the time to wipe the cap and tube clean before withdrawing the dipstick.
Engine coolant in the transmission fluid is generally caused by a cooler malfunction. The only
remedy is to replace the radiator as the cooler in the radiator is not a serviceable part. If coolant
has circulated through the transmission, an overhaul is necessary.
The torque converter should also be replaced whenever a failure generates sludge and debris. This
is necessary because normal converter flushing procedures will not remove all contaminants.

Level Check
Fluid - A/T: Service and Repair Fluid Level Check
FLUID LEVEL CHECK
Low fluid level can cause a variety of conditions because it allows the pump to take in air along with
the fluid. As in any hydraulic system, air bubbles make the fluid spongy, therefore, pressures will be
low and build up slowly.
Improper filling can also raise the fluid level too high. When the transmission has too much fluid,
the geartrain churns up foam and cause the same conditions which occur with a low fluid level.
In either case, air bubbles can cause overheating and/or fluid oxidation, and varnishing. This can
interfere with normal valve, clutch, and accumulator operation. Foaming can also result in fluid
escaping from the transmission vent where it may be mistaken for a leak.
After the fluid has been checked, seat the dipstick fully to seal out water and dirt.
The transmission has a dipstick to check oil level. It is located on the right side of the engine. Be
sure to wipe all dirt from dipstick handle before removing.
The torque converter fills in both the P (PARK) and N (NEUTRAL) positions. Place the selector
lever in P (PARK) to be sure that the fluid level check is accurate. The engine should be running at
idle speed for at least one minute, with the vehicle on level ground. At normal operating
temperature (approximately 82°C. or 180°F), the fluid level is correct if it is in the HOT region
(cross-hatched area) on the oil level indicator. The fluid level will be approximately at the upper
COLD hole of the dipstick at 70°F fluid temperature.
NOTE: Engine and Transmission should be at normal operating temperature before performing this
procedure.
1. Start engine and apply parking brake. 2. Shift the transmission into DRIVE for approximately 2
seconds. 3. Shift the transmission into REVERSE for approximately 2 seconds. 4. Shift the
transmission into PARK. 5. Hook up scan tool and select transmission. 6. Select sensors. 7. Read
the transmission temperature value. 8. Compare the fluid temperature value with the chart. 9.
Adjust transmission fluid level shown on the dipstick according to the Transmission Fluid
Temperature Chart.
NOTE: After adding any fluid to the transmission, wait a minimum of 2 minutes for the oil to fully
drain from the fill tube into the transmission before rechecking the fluid level.

Fluid - A/T: Service and Repair Fluid and Filter Service
FLUID AND FILTER REPLACEMENT
For proper service intervals Refer to LUBRICATION & MAINTENANCE.
REMOVAL
1. Hoist and support vehicle on safety stands. 2. Place a large diameter shallow drain pan beneath
the transmission pan. 3. Remove bolts holding front and sides of pan to transmission. 4. Loosen
bolts holding rear of pan to transmission. 5. Slowly separate front of pan away from transmission
allowing the fluid to drain into drain pan. 6. Hold up pan and remove remaining bolts holding pan to
transmission. 7. While holding pan level, lower pan away from transmission. 8. Pour remaining fluid
in pan into drain pan.
9. Remove the screw holding the primary oil filter (1) to valve body.
10. Separate filter from valve body and oil pump and pour fluid in filter into drain pan. 11. Inspect
the oil filter seal in the bottom of the oil pump. If the seal is not installed completely in the oil pump,
or is otherwise damaged, then remove
and discard the oil filter seal from the bottom of the oil pump. If the seal is installed correctly and is
in good condition, it can be reused.
12. If replacing the cooler return filter (2), use Oil Filter Wrench 8321 to remove the filter from the
transmission. 13. Dispose of used trans fluid and filter(s) properly.
INSPECTION
Inspect bottom of pan and magnet for excessive amounts of metal. A light coating of clutch material
on the bottom of the pan does not indicate a problem unless accompanied by a slipping condition
or shift lag. If fluid and pan are contaminated with excessive amounts of debris, refer to the
diagnosis.
CLEANING
1. Using a suitable solvent, clean pan and magnet. 2. Using a suitable gasket scraper, clean
original sealing material from surface of transmission case and the transmission pan.
INSTALLATION
CAUTION: The primary oil filter seal MUST be fully installed flush against the oil pump body. DO
NOT install the seal onto the filter neck and attempt to install the filter and seal as an assembly.
Damage to the transmission will result.
1. If necessary, install a new primary oil filter seal in the oil pump inlet bore. Seat the seal in the
bore with a suitable tool (appropriately sized drift or
socket, the butt end of a hammer, or other suitable tool).
2. Place replacement filter in position on valve body and into the oil pump. 3. Install screw to hold
the primary oil filter (1) to valve body. Tighten screw to 4.5 Nm (40 inch lbs.) torque. 4. Install new
cooler return filter (2) onto the transmission, if necessary. Torque the filter to 14.12 Nm (125 inch
lbs.). 5. Place bead of Mopar(R) RTV sealant onto the transmission case sealing surface. 6. Place
pan in position on transmission. 7. Install bolts to hold pan to transmission. Tighten bolts to 11.8
Nm (105 inch lbs.) torque. 8. Lower vehicle and fill transmission with Mopar(R) ATF +4.

Fluid - A/T: Service and Repair Transmission Fill
TRANSMISSION FILL
To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:
1. Remove dipstick and insert clean funnel in transmission fill tube. 2. Add following initial quantity
of Mopar(R) ATF +4 to transmission:
a. If only fluid and filter were changed, add 10 pints (5 quarts) of ATF +4 to transmission. b. If
transmission was completely overhauled and the torque converter was replaced or drained, add 24
pints (12 quarts) of ATF +4 to
transmission.
3. Check the transmission fluid and adjust as required.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

DISCUSSION:
The axle fill holes on some Dodge Truck vehicle axles may be located considerably higher than the
actual fluid level. Filling the axle until the fluid comes out of the fill hole will over fill the axle, which
may cause fluid foaming. When checking fluid level or filling a rear axle with fluid, you must
measure the distance from the bottom of the fill hole to the top of the actual fluid level. This can
easily be accomplished using a pipe cleaner or piece of wire. Make a 90 degree bend in the wire 2
inches from the end. The wire can then be inserted into the axle fill hole to use as a dipstick.
Measure the distance from the bend to the oil level. The fluid levels for the axles are shown in the
table below.

MS-6395. MS-6395 contains requirements, not addressed by API Certification, that provide
additional protection for Chrysler Group engines. All Chrysler Group gasoline engines, irrespective
of model year, should be serviced with API Certified engine oils meeting MS-6395. Chrysler Group
Engines are developed, certified and filled with engine oil of the designated viscosity grade,
meeting MS-6395, and should be serviced with the correct viscosity grade engine oil. The following
table contains the correct viscosity grades for the 2005 model year.

API SERVICE GRADE CERTIFIED Use an engine oil that is API Certified. MOPAR provides
engine oils, that meet or exceed this requirement.
SAE VISCOSITY An SAE viscosity grade is used to specify the viscosity of engine oil. Use only
engine oils with multiple viscosities such as 5W-30 or 10W-30. These are specified with a dual SAE
viscosity grade which indicates the cold-to-hot temperature viscosity range. Select an engine oil
that is best suited to your particular temperature range and variation. For 3.7L/4.7L engines SAE
5W-30 engine oil is recommended for all operating temperatures. For 5.7L engines SAE 5W-20
engine oil is recommended for all operating temperatures.These engine oils improve low
temperature starting and vehicle fuel economy. Refer to your engine oil filler cap for the
recommended engine oil viscosity for your vehicle.

Engine Oil: Initial Inspection and Diagnostic Overview
DIAGNOSIS AND TESTING - ENGINE OIL LEAK
Begin with a thorough visual inspection of the engine, particularly at the area of the suspected leak.
If an oil leak source is not readily identifiable, the following steps should be followed: 1. Do not
clean or degrease the engine at this time because some solvents may cause rubber to swell,
temporarily stopping the leak. 2. Add an oil soluble dye (use as recommended by manufacturer).
Start the engine and let idle for approximately 15 minutes. Check the oil dipstick
to make sure the dye is thoroughly mixed as indicated with a bright yellow color under a black light.
3. Using a black light, inspect the entire engine for fluorescent dye, particularly at the suspected
area of oil leak. If the oil leak is found and
identified, repair defect.
4. If dye is not observed, drive the vehicle at various speeds for approximately 24 km (15 miles),
and repeat inspection. If the oil leak source is not
positively identified at this time, proceed with the air leak detection test method.
Air Leak Detection Test Method 1. Remove the PCV valve from the IAFM. Cap or plug the PCV
valve grommet. 2. Attach an air hose with pressure gauge and regulator to the dipstick tube.
CAUTION: Do not subject the engine assembly to more than 20.6 kPa (3 PSI) of test pressure.
3. Gradually apply air pressure from 1 psi to 2.5 psi maximum while applying soapy water at the
suspected source. Adjust the regulator to the
suitable test pressure that provide the best bubbles which will pinpoint the leak source. If the oil
leak is detected and identified, repair defect.
4. If the leakage occurs at the rear oil seal area, refer to Inspection for Rear Seal Area Leak. 5. If
no leaks are detected, turn off the air supply and remove the air hose and all plugs and caps. Install
the PCV valve. 6. Clean the oil off the suspect oil leak area using a suitable solvent. Drive the
vehicle at various speeds approximately 24 km (15 miles). Inspect
the engine for signs of an oil leak by using a black light.

Engine Oil: Component Tests and General Diagnostics
INSPECTION FOR REAR SEAL AREA LEAKS
Since it is sometimes difficult to determine the source of an oil leak in the rear seal area of the
engine, a more involved inspection is necessary. The following steps should be followed to help
pinpoint the source of the leak.
If the leakage occurs at the crankshaft rear oil seal area: 1. Disconnect the battery. 2. Raise the
vehicle. 3. Remove torque converter or clutch housing cover and inspect rear of block for evidence
of oil. Use a black light to check for the oil leak:
a. Circular spray pattern generally indicates seal leakage or crankshaft damage. b. Where leakage
tends to run straight down, possible causes are a porous block, distributor seal, camshaft bore cup
plugs oil galley pipe plugs,
oil filter runoff, and main bearing cap to cylinder block mating surfaces.
4. If no leaks are detected, pressurize the crankcase as outlined in the, Inspection (Engine oil
Leaks in general).
CAUTION: Do not exceed 20.6 kPa (3 psi).
5. If the leak is not detected, very slowly turn the crankshaft and watch for leakage. If a leak is
detected between the crankshaft and seal while slowly
turning the crankshaft, it is possible the crankshaft seal surface is damaged. The seal area on the
crankshaft could have minor nicks or scratches that can be polished out with emery cloth.
CAUTION: Use extreme caution when crankshaft polishing is necessary to remove minor nicks and
scratches. The crankshaft seal flange is especially machined to complement the function of the
rear oil seal.
6. For bubbles that remain steady with shaft rotation, no further inspection can be done until
disassembled.

Engine Oil: Service and Repair
OIL
STANDARD PROCEDURE - ENGINE OIL SERVICE
The engine oil level indicator is located at the left hand of the engine on the 5.7L engines.
CRANKCASE OIL LEVEL INSPECTION
CAUTION: Do not overfill crankcase with engine oil, pressure loss or oil foaming can result.
Inspect engine oil level approximately every 800 kilometers (500 miles). Unless the engine has
exhibited loss of oil pressure, run the engine for about ten minutes before checking oil level.
Checking engine oil level on a cold engine is not accurate. To ensure proper lubrication of an
engine, the engine oil must be maintained at an acceptable level. The acceptable levels are
indicated between the ADD and SAFE marks on the engine oil dipstick. 1. Position vehicle on level
surface. 2. With engine OFF, allow approximately five minutes for oil to settle to bottom of
crankcase, remove engine oil dipstick. 3. Wipe dipstick clean. 4. Install dipstick and verify it is
seated in the tube. 5. Remove dipstick, with handle held above the tip, take oil level reading. 6. Add
oil only if level is below the ADD mark on dipstick.
ENGINE OIL CHANGE
Change engine oil at mileage and time intervals described in Maintenance Schedules. Run engine
until achieving normal operating temperature. 1. Position the vehicle on a level surface and turn
engine off. 2. Hoist and support vehicle on safety stands. 3. Remove oil fill cap. 4. Place a suitable
drain pan under crankcase drain. 5. Remove drain plug from crankcase and allow oil to drain into
pan. Inspect drain plug threads for stretching or other damage. Replace drain plug if
damaged.
6. Install drain plug in crankcase. Torque to 34 Nm (25 ft. lbs.). 7. Lower vehicle and fill crankcase
with specified type and amount of engine oil described. 8. Install oil fill cap. 9. Start engine and
inspect for leaks.
10. Stop engine and inspect oil level.
USED ENGINE OIL DISPOSAL
Care should be exercised when disposing used engine oil after it has been drained from a vehicle
engine.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

DISCUSSION:
Do not use fluids or supplements that contain Teflon as they will cause a restriction at the filter in
the power steering fluid reservoir, causing severe damage to the steering system. The power
steering fluid used in Chrysler Group vehicles is an engineered product, the addition of ANY
unapproved fluids or supplements can interfere with the proper function of the fluid and cause
damage to the steering system. To ensure the performance and durability of Chrysler Group
steering systems, use only Mopar Power Steering Fluid +4, ATF+4 Automatic Transmission Fluid,
or equivalent (MS-9602), in the power steering system.

FLUID
NOTE: It is normal that some pressure will build up inside the reservoir, especially, with a warm
vehicle. A slight popping noise upon removal of the cap is normal. The fluid level should read
between the ADD and the FULL COLD marks. When the fluid is hot it should read between ADD
and FULL HOT marks. Only add fluid when the vehicle is cold.
The recommended fluid for the power steering system is Mopar(R) ATF +4.
Mopar(R) ATF+4, when new is red in color. The ATF+4 is dyed red so it can be identified from
other fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and
is not an indicator of fluid condition, As the vehicle is driven, the ATF+4 will begin to look darker in
color and may eventually become brown. THIS IS NORMAL. ATF+4 also has a unique odor that
may change with age. Consequently, odor and color cannot be used to indicate the fluid condition
or the need for a fluid change.

POWER STEERING FLUID LEVEL CHECKING
WARNING: FLUID LEVEL SHOULD BE CHECKED WITH THE ENGINE OFF TO PREVENT
PERSONAL INJURY FROM MOVING PARTS.
CAUTION: MOPAR(R) ATF+4 is to be used in the power steering system. No other power steering
or automatic transmission fluid is to be used in the system. Damage may result to the power
steering pump and system if any other fluid is used, and do not overfill.
The power steering fluid level can be viewed on the dipstick attached to the filler cap. There are
two ranges listed on the dipstick, COLD and HOT. Before opening power steering system, wipe the
reservoir filler cap free of dirt and debris. Remove the cap and check the fluid level on its dipstick.
When the fluid is at normal ambient temperature, approximately 21°C to 27°C (70°F to 80°F), the
fluid level should read between the minimum and maximum area of the cold range. When the fluid
is hot, fluid level is allowed to read up to the highest end of the HOT range. Only add fluid when the
vehicle is cold.
Use only Mopar(R) ATF+4 Do not overfill the power steering system.

Refrigerant: Description and Operation
The refrigerant used in this air conditioning system is a HydroFluoroCarbon (HFC), type R-134a.
Unlike R-12, which is a ChloroFluoroCarbon (CFC), R-134a refrigerant does not contain
ozone-depleting chlorine. R-134a refrigerant is a non-toxic, non-flammable, clear, and colorless
liquefied gas.
Even though R-134a does not contain chlorine, it must be reclaimed and recycled just like
CFC-type refrigerants. This is because R-134a is a greenhouse gas and can contribute to global
warming.
R-134a refrigerant is not compatible with R-12 refrigerant in an A/C system. Even a small amount
of R-12 refrigerant added to an R-134a refrigerant system will cause A/C compressor failure,
refrigerant oil sludge or poor A/C system performance. In addition, the polyalkylene glycol (PAG)
synthetic refrigerant oils used in an R-134a refrigerant system are not compatible with the
mineral-based refrigerant oils used in an R-12 refrigerant system.
R-134a refrigerant system service ports, service tool couplers and refrigerant dispensing bottles
have all been designed with unique fittings to ensure that an R-134a refrigerant system is not
accidentally contaminated with the wrong refrigerant (R-12). There are also labels posted in the
engine compartment of the vehicle and on the A/C compressor to identify that the A/C system is
equipped with R-134a refrigerant.

WARNING: REFER TO THE APPLICABLE WARNINGS AND CAUTIONS FOR THIS SYSTEM
BEFORE PERFORMING THE FOLLOWING OPERATION. FAILURE TO FOLLOW THE
WARNINGS AND CAUTIONS COULD RESULT IN POSSIBLE PERSONAL INJURY OR DEATH.
NOTE: Always refer to the underhood HVAC Specification Label for the refrigerant fill specification
of the vehicle being serviced.
After all refrigerant system leaks have been repaired and the refrigerant system has been
evacuated, a refrigerant charge can be injected into the system. For the proper amount of the
refrigerant charge, refer to the underhood HVAC Specification Label.
A R-134a refrigerant recovery/recycling/charging station that meets SAE Standard J2210 must be
used to charge the refrigerant system with R-134a refrigerant. Refer to the operating instructions
supplied by the equipment manufacturer for proper care and use of this equipment.
CHARGING PROCEDURE
CAUTION: A small amount of refrigerant oil is removed from the A/C system each time the
refrigerant system is recovered and evacuated. Before charging the A/C system, you MUST
replenish any oil lost during the recovery process. Refer the equipment manufacturer instructions
for more information.
1. Evacuate the refrigerant system. 2. A manifold gauge set and an R-134a refrigerant
recovery/recycling/charging station that meets SAE standard J2210 should be connected to the
refrigerant system.
3. Measure the proper amount of refrigerant and heat it to 52° C (125° F) with the charging station.
See the operating instructions supplied by the
equipment manufacturer for proper use of this equipment.
4. Open both the suction and discharge valves, then open the charge valve to allow the heated
refrigerant to flow into the system. 5. When the transfer of refrigerant has stopped, close both the
suction and discharge valves. 6. If all of the refrigerant charge did not transfer from the dispensing
device, open all of the windows in the vehicle and set the heating-A/C system
controls so that the A/C compressor is engaged and the blower motor is operating at its lowest
speed setting. Run the engine at a steady high idle (about 1400 rpm). If the A/C compressor does
not engage, test the compressor clutch control circuit and repair as required.
7. Open the low-side valve to allow the remaining refrigerant to transfer to the refrigerant system.
WARNING: TAKE CARE NOT TO OPEN THE DISCHARGE (HIGH PRESSURE) VALVE AT THIS
TIME. FAILURE TO FOLLOW THIS WARNING COULD RESULT IN POSSIBLE PERSONAL
INJURY OR DEATH.
8. Disconnect the charging station and manifold gauge set from the refrigerant system service
ports. 9. Reinstall the caps onto the refrigerant system service ports.

Refrigerant Oil: Description and Operation
The refrigerant oil used in R-134a refrigerant systems is a synthetic-based, polyalkylene glycol
(PAG), wax-free lubricant. Mineral-based R-12 refrigerant oils are not compatible with PAG oils,
and should never be introduced to an R-134a refrigerant system.
There are different PAG oils available, and each contains a different additive package. Use only
refrigerant oil of the same type as recommended to service the refrigerant system (always refer to
the specification tag included with the replacement A/C compressor or the underhood A/C system
specification tag).
The Sanden SD-7 A/C compressor used in this vehicle is designed to use ND-15 PAG refrigerant
oil. Use only this type of refrigerant oil when servicing the A/C compressor for the 5.9L Diesel
engine.
The Denso 10S17 A/C compressor used in this vehicle is designed to use ND-8 PAG refrigerant
oil. Use only this type of refrigerant oil when servicing the A/C compressor for the 3.7L, 4.7L, 5.7L
and 8.3L engines.
After performing any refrigerant recovery or recycling operation, always replenish the refrigerant
system with the same amount of the recommended refrigerant oil as was removed. Too little
refrigerant oil can cause A/C compressor damage, and too much can reduce A/C system
performance.
PAG refrigerant oil is more hygroscopic than mineral oil, and will absorb any moisture it comes into
contact with, even moisture in the air. The PAG oil container should always be kept tightly capped
until it is ready to be used. After use, recap the oil container immediately to prevent moisture
contamination.

Refrigerant Oil: Service and Repair
REFRIGERANT OIL LEVEL
When an A/C system is assembled at the factory, all components except the A/C compressor are
refrigerant oil free. After the refrigerant system has been charged and operated, the refrigerant oil
in the A/C compressor is dispersed throughout the refrigerant system. The accumulator, A/C
evaporator, A/C condenser and the A/C compressor will each retain a significant amount of the
needed refrigerant oil.
It is important to have the correct amount of refrigerant oil in the A/C system. This ensures proper
lubrication of the A/C compressor. Too little oil will result in damage to the A/C compressor, while
too much oil will reduce the cooling capacity of the A/C system and consequently result in higher
discharge air temperatures.
CAUTION: The refrigerant oil in the R-134a A/C system is unique depending on the A/C
compressor used. Use only PAG oils that are designed to work with R-134a refrigerant and the A/C
compressor in the vehicle. Always refer to the underhood A/C System Specification Label for the
correct oil designation. The oil container should be kept tightly capped until it is ready for use and
then tightly capped after use to prevent contamination from dirt and moisture. Refrigerant oil will
quickly absorb any moisture it comes in contact with, therefore, special effort must be used to keep
all R-134a system components moisture-free. Moisture in the refrigerant oil is very difficult to
remove and will cause a reliability problem with the A/C compressor.
NOTE: Most reclaim/recycling equipment will measure the lubricant being removed during
recovery. This amount of lubricant should be added back into the system. Refer to the
reclaim/recycling equipment manufacturers instructions.
It will not be necessary to check the oil level in the A/C compressor or to add oil, unless there has
been an oil loss. An oil loss may occur due to a rupture or leak from a refrigerant line, a connector
fitting, a component, or a component seal. If a leak occurs, add 30 milliliters (1 fluid ounce) of
refrigerant oil to the refrigerant system after the repair has been made. Refrigerant oil loss will be
evident at the leak point by the presence of a wet, shiny surface around the leak.
Refrigerant Oil Capacities
Refrigerant oil must be added when an accumulator, A/C evaporator or A/C condenser is replaced.
See the Refrigerant Oil Capacities chart. When an A/C compressor is replaced, the refrigerant oil
must be drained from the old compressor and measured. Drain all of the refrigerant oil from the
new A/C compressor, then fill the new compressor with the same amount of refrigerant oil that was
drained out of the old compressor.

Malfunction Indicator Lamp: Description and Operation
A Malfunction Indicator Lamp (MIL) is standard equipment on all instrument clusters. This indicator
is located on the left side of the instrument cluster, to the left of the voltage gauge.
The MIL consists of a stencil-like cutout of the International Control and Display Symbol icon for
"Engine" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. An amber Light Emitting
Diode (LED) behind the cutout in the opaque layer of the overlay causes the icon to appear in
amber through the translucent outer layer of the overlay when the indicator is illuminated from
behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The MIL
is serviced as a unit with the instrument cluster.
The Malfunction Indicator Lamp (MIL) gives an indication to the vehicle operator when the
Powertrain Control Module (PCM) on vehicles with a gasoline engine, or the Engine Control
Module (ECM) on vehicles with a diesel engine has recorded a Diagnostic Trouble Code (DTC) for
an On-Board Diagnostics II (OBDII) emissions-related circuit or component malfunction. The MIL is
controlled by a transistor on the instrument cluster circuit board based upon cluster programming
and electronic messages received by the cluster from the PCM or ECM over the Programmable
Communications Interface (PCI) data bus.
The MIL Light Emitting Diode (LED) is completely controlled by the instrument cluster logic circuit,
and that logic will only allow this indicator to operate when the instrument cluster receives a battery
current input on the fused ignition switch output (run-start) circuit. Therefore, the LED will always be
off when the ignition switch is in any position except On or Start. The LED only illuminates when it
is provided a path to ground by the instrument cluster transistor. The instrument cluster will turn on
the MIL for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the indicator is illuminated for
about two seconds as a bulb test. The entire bulb test is a function of the PCM or ECM.
- MIL Lamp-On Message - Each time the cluster receives a MIL lamp-on message from the PCM or
ECM, the indicator will be illuminated. The indicator can be flashed on and off, or illuminated solid,
as dictated by the PCM or ECM message. For some DTC's, if a problem does not recur, the PCM
or ECM will send a lamp-off message automatically. Other DTC's may require that a fault be
repaired and the PCM or ECM be reset before a lamp-off message will be sent.
- Communication Error - If the cluster receives no messages from the PCM or ECM for about ten
seconds, the MIL is illuminated by the instrument cluster to indicate a loss of bus communication.
The indicator remains controlled and illuminated by the cluster until a valid message is received
from the PCM or ECM.
- Actuator Test - Each time the cluster is put through the actuator test, the MIL indicator will be
turned on during the bulb check portion of the test to confirm the functionality of the LED and the
cluster control circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the fuel and emissions system
circuits and sensors to decide whether the system is in good operating condition. On vehicles with
a diesel engine, the ECM continually monitors the fuel and emissions system circuits and sensors
to decide whether the system is in good operating condition. The PCM or ECM then sends the
proper lamp-on or lamp-off messages to the instrument cluster. For further diagnosis of the MIL or
the instrument cluster circuitry that controls the LED, refer to testing. If the instrument cluster turns
on the MIL after the bulb test, it may indicate that a malfunction has occurred and that the fuel and
emissions systems may require service.
For proper diagnosis of the fuel and emissions systems, the PCM, the ECM, the PCI data bus, or
the electronic message inputs to the instrument cluster that control the MIL, a diagnostic scan tool
is required.

NOTE:
This information applies to any model equipped with Chrome Clad Wheels.
DISCUSSION:
Models equipped with Chrome Clad wheels require specific piloting on balance equipment to
properly center the wheel and prevent damage to the chrome clad surface. The chrome cladding is
not removable or replaceable and has cladding tabs that extend into the wheel bore. Traditional
high-taper cones will come into contact with the cladding tabs rather than properly seat on the hub
bore chamfer. Many modern aluminum wheel designs cannot be mounted with traditional cones.
Direct-Fit Collets should be used to properly mount clad wheels on balance equipment (Fig 1).
SPECIAL TOOLS/EQUIPMENT REQUIRED:
NOTE:
This kit includes the adapters for all Dodge, Chrysler & Jeep models with clad wheels. Individual
adapters for specific wheel sizes can be ordered separately. To order a kit or individual adapters,
contact Pentastar Service Equipment @ 1-800-223-5623.

Wheels: Description and Operation
WHEELS
DESCRIPTION
Original equipment wheels are designed for the specified Maximum Vehicle Capacity. All models
use steel or aluminum drop center wheels. Aluminum wheels require special balance weights and
alignment equipment.
1. On vehicles equipped with dual rear wheels, The rim is an eight stud hole pattern wheel. The
wheels have a flat mounting surface (1).
2. The slots (1) in the wheel must be aligned to provide access to the valve stem.
WHEEL DESIGN
The rim size is on the vehicle safety certification label located on the drivers door shut face. The
size of the rim is determined by the drivetrain package. Original equipment wheels/rims are
designed for operation up to the specified maximum vehicle capacity.
All models use stamped steel, cast aluminum or forged aluminum wheels. Every wheel has raised
sections between the rim flanges (1) and rim drop well (3) called safety humps.
Initial inflation of the tire forces the bead over these raised sections. In case of rapid loss of air
pressure, the raised sections help hold the tire on the

wheel.
The wheel studs and nuts are designed for specific applications. All aluminum and some steel
wheels have wheel stud nuts with an enlarged nose. This enlarged nose is necessary to ensure
proper retention of the wheels. Do not use replacement studs or nuts with a different design or
lesser quality.

Wheels: Testing and Inspection
WHEEL INSPECTION
Inspect wheels for:
- Excessive runout
- Dents, cracks or irregular bends
- Damaged wheel stud (lug) holes
- Air Leaks
NOTE: Do not attempt to repair a wheel by hammering, heating or welding.
If a wheel is damaged, an original equipment replacement wheel should be used. When obtaining
replacement wheels, they must be equivalent in load carrying capacity. The diameter, width, offset,
pilot hole and bolt circle of the wheel should be the same as the original wheel.
WARNING: Failure to use equivalent replacement wheels may adversely affect the safety and
handling of the vehicle.
WARNING: Replacement with used wheels is not recommended. The service history of the wheel
may have included severe treatment or very high mileage. The rim could fail without warning.
WARNING: DaimlerChrysler Corporation does not recommend that customers use "reconditioned"
wheels (wheels that have been damaged and repaired) because they can result in a sudden
catastrophic wheel failure which could cause loss of control and result in injury or death. For
clarification:
- Cosmetic refinishing for the purpose of repairing a superficial flaw is an acceptable procedure
providing it is limited to paint or clear coat only, the wheel is not modified in any way, and there is
no exposure to paint curing heat over 200 degrees Fahrenheit.
- Damaged wheels are those which have been bent, broken, cracked or sustained some other
physical damage which may have compromised the wheel structure.
- Repaired indicates that the wheel has been modified through bending, welding, heating,
straightening, or material removal to rectify damage.
- Re-plating of chrome plated wheels is not an acceptable procedure nor is chrome plating of
original equipment painted or polished wheels, as this may alter mechanical properties and affect
fatigue life.

TAPPETS - HYDRAULIC ROLLER
DIAGNOSIS AND TESTING - HYDRAULIC TAPPETS
Before disassembling any part of the engine to correct tappet noise, check the oil pressure. If
vehicle has no oil pressure gauge, install a reliable gauge at the pressure sending-unit. The
pressure should be between 207 - 552 kPa (30 - 70 psi) at 3,000 RPM.
Check the oil level after the engine reaches normal operating temperature. Allow 5 minutes to
stabilize oil level, check dipstick. The oil level in the pan should never be above the FULL mark or
below the ADD OIL mark on dipstick. Either of these two conditions could be responsible for noisy
tappets.
OIL LEVEL
HIGH If oil level is above the FULL mark, it is possible for the connecting rods to dip into the oil.
With the engine running, this condition could create foam in the oil pan. Foam in oil pan would be
fed to the hydraulic tappets by the oil pump causing them to lose length and allow valves to seat
noisily.
LOW Low oil level may allow oil pump to take in air. When air is fed to the tappets, they lose length,
which allows valves to seat noisily. Any leaks on intake side of oil pump through which air can be
drawn will create the same tappet action. Check the lubrication system from the intake strainer to
the pump cover, including the relief valve retainer cap. When tappet noise is due to aeration, it may
be intermittent or constant, and usually more than one tappet will be noisy. When oil level and
leaks have been corrected, operate the engine at fast idle. Run engine for a sufficient time to allow
all of the air inside the tappets to be bled out.
TAPPET NOISE DIAGNOSIS
1. To determine source of tappet noise, crank over engine with cylinder head covers removed. 2.
Feel each valve spring or rocker arm to detect noisy tappet. The noisy tappet will cause the
affected spring and/or rocker arm to vibrate or feel
rough in operation.
NOTE: Worn valve guides or cocked springs are sometimes mistaken for noisy tappets. If such is
the case, noise may be dampened by applying side thrust on the valve spring. If noise is not
appreciably reduced, it can be assumed the noise is in the tappet. Inspect the rocker arm push rod
sockets and push rod ends for wear.
3. Valve tappet noise ranges from light noise to a heavy click. A light noise is usually caused by
excessive leakdown around the unit plunger, or by
the plunger partially sticking in the tappet body cylinder. The tappet should be replaced. A heavy
click is caused by a tappet check valve not seating, or by foreign particles wedged between the
plunger and the tappet body. This will cause the plunger to stick in the down position. This heavy
click will be accompanied by excessive clearance between the valve stem and rocker arm as valve
closes. In either case, tappet assembly should be removed for inspection and cleaning.
4. The valve train generates a noise very much like a light tappet noise during normal operation.
Care must be taken to ensure that tappets are making
the noise. If more than one tappet seems to be noisy, it's probably not the tappets.

Piston: Description and Operation
PISTON & CONNECTING ROD
DESCRIPTION
CAUTION: Do not use a metal stamp to mark connecting rods as damage may result, instead use
ink or a scratch awl.
The pistons are made of a high strength aluminum alloy. Piston skirts are coated with a solid
lubricant (Molykote) to reduce friction and provide scuff resistance. The piston top ring groove and
land is anodized. The connecting rods are made of forged powdered metal, with a "fractured cap"
design. A pressed fit piston pin is used to attach the piston and connecting rod.

Piston: Procedures
STANDARD PROCEDURE - PISTON FITTING
1. To correctly select the proper size piston, a cylinder bore gauge, capable of reading in 0.003 mm
(0.0001 inch) INCREMENTS is required. If a
bore gauge is not available, do not use an inside micrometer.
2. Measure the inside diameter of the cylinder bore at a point 38.0 mm (1.5 inches) below top of
bore. Start perpendicular (across or at 90 degrees)
to the axis of the crankshaft at point A and then take an additional bore reading 90 degrees to that
at point B.
3. The coated pistons will be serviced with the piston pin and connecting rod pre-assembled. The
piston-rod assembly is specific for the left cylinder
bank (odd numbered) and the right cylinder bank (even numbered) and must not be interchanged.
4. The coating material is applied to the piston after the final piston machining process. Measuring
the outside diameter of a coated piston will not
provide accurate results. Therefore measuring the inside diameter of the cylinder bore with a dial
Bore Gauge is MANDATORY. To correctly select the proper size piston, a cylinder bore gauge
capable of reading in 0.003 mm (0.0001 inch) increments is required.
5. Piston installation into the cylinder bore requires slightly more pressure than that required for
non-coated pistons. The bonded coating on the
piston will give the appearance of a line-to-line fit with the cylinder bore.

Valve: Service and Repair Refacing Valves & Seats
STANDARD PROCEDURE- REFACING
NOTE: Valve seats that are worn or burned can be reworked, provided that correct angle and seat
width are maintained. Otherwise the cylinder head must be replaced.
NOTE: When refacing valves and valve seats, it is important that the correct size valve guide pilot
be used for reseating stones. A true and complete surface must be obtained.
1. Using a suitable dial indicator measure the center of the valve seat Total run out must not
exceed 0.051 mm (0.002 inch). 2. Apply a small amount of Prussian blue to the valve seat, insert
the valve into the cylinder head, while applying light pressure on the valve rotate
the valve. Remove the valve and examine the valve face. If the blue is transferred below the top
edge of the valve face, lower the valve seat using a 15 degree stone. If the blue is transferred to
the bottom edge of the valve face, raise the valve seat using a 65 degree stone.
3. When the seat is properly positioned the width of the intake seat must be 1.018 - 1.62 mm
(0.0464 - 0.0637 inch) and the exhaust seat must be
1.48 - 1.92 mm (0.058 - 0.075 inch).
4. Check the valve spring installed height after refacing the valve and seat. The installed height for
both intake and exhaust valve springs must not
exceed 46.0 mm (1.81 inch).
VALVE FACE AND VALVE SEAT ANGLE CHART
5. The valve seat must maintain an angle of 44.5 - 45.0 degrees angle. 6. The valve face must
maintain a face angle of 45.0 - 45.5 degrees angle.

BELT - DRIVE
DIAGNOSIS AND TESTING
ACCESSORY DRIVE BELT
VISUAL DIAGNOSIS
NOTE: 5.9L Diesel Engine - If a belt is broken or frayed, inspect engine speed sensor (located near
the crankshaft damper) for damage.
When diagnosing serpentine accessory drive belts, small cracks that run across the ribbed surface
of the belt from rib to rib, are considered normal. These are not a reason to replace the belt.
However, cracks running along a rib (not across) are not normal. Any belt with cracks running
along a rib must be replaced. Also replace the belt if it has excessive wear, frayed cords or severe
glazing.
Refer to ACCESSORY DRIVE BELT DIAGNOSIS CHART for further belt diagnosis.
NOISE DIAGNOSIS
Noises generated by the accessory drive belt are most noticeable at idle. Before replacing a belt to
resolve a noise condition, inspect all of the accessory drive pulleys for alignment, glazing, or
excessive end play.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

API SERVICE GRADE CERTIFIED Use an engine oil that is API Certified. MOPAR provides
engine oils, that meet or exceed this requirement.
SAE VISCOSITY An SAE viscosity grade is used to specify the viscosity of engine oil. Use only
engine oils with multiple viscosities such as 5W-30 or 10W-30. These are specified with a dual SAE
viscosity grade which indicates the cold-to-hot temperature viscosity range. Select an engine oil
that is best suited to your particular temperature range and variation. For 3.7L/4.7L engines SAE
5W-30 engine oil is recommended for all operating temperatures. For 5.7L engines SAE 5W-20
engine oil is recommended for all operating temperatures.These engine oils improve low
temperature starting and vehicle fuel economy. Refer to your engine oil filler cap for the
recommended engine oil viscosity for your vehicle.

Engine Oil: Initial Inspection and Diagnostic Overview
DIAGNOSIS AND TESTING - ENGINE OIL LEAK
Begin with a thorough visual inspection of the engine, particularly at the area of the suspected leak.
If an oil leak source is not readily identifiable, the following steps should be followed: 1. Do not
clean or degrease the engine at this time because some solvents may cause rubber to swell,
temporarily stopping the leak. 2. Add an oil soluble dye (use as recommended by manufacturer).
Start the engine and let idle for approximately 15 minutes. Check the oil dipstick
to make sure the dye is thoroughly mixed as indicated with a bright yellow color under a black light.
3. Using a black light, inspect the entire engine for fluorescent dye, particularly at the suspected
area of oil leak. If the oil leak is found and
identified, repair defect.
4. If dye is not observed, drive the vehicle at various speeds for approximately 24 km (15 miles),
and repeat inspection. If the oil leak source is not
positively identified at this time, proceed with the air leak detection test method.
Air Leak Detection Test Method 1. Remove the PCV valve from the IAFM. Cap or plug the PCV
valve grommet. 2. Attach an air hose with pressure gauge and regulator to the dipstick tube.
CAUTION: Do not subject the engine assembly to more than 20.6 kPa (3 PSI) of test pressure.
3. Gradually apply air pressure from 1 psi to 2.5 psi maximum while applying soapy water at the
suspected source. Adjust the regulator to the
suitable test pressure that provide the best bubbles which will pinpoint the leak source. If the oil
leak is detected and identified, repair defect.
4. If the leakage occurs at the rear oil seal area, refer to Inspection for Rear Seal Area Leak. 5. If
no leaks are detected, turn off the air supply and remove the air hose and all plugs and caps. Install
the PCV valve. 6. Clean the oil off the suspect oil leak area using a suitable solvent. Drive the
vehicle at various speeds approximately 24 km (15 miles). Inspect
the engine for signs of an oil leak by using a black light.

Engine Oil: Component Tests and General Diagnostics
INSPECTION FOR REAR SEAL AREA LEAKS
Since it is sometimes difficult to determine the source of an oil leak in the rear seal area of the
engine, a more involved inspection is necessary. The following steps should be followed to help
pinpoint the source of the leak.
If the leakage occurs at the crankshaft rear oil seal area: 1. Disconnect the battery. 2. Raise the
vehicle. 3. Remove torque converter or clutch housing cover and inspect rear of block for evidence
of oil. Use a black light to check for the oil leak:
a. Circular spray pattern generally indicates seal leakage or crankshaft damage. b. Where leakage
tends to run straight down, possible causes are a porous block, distributor seal, camshaft bore cup
plugs oil galley pipe plugs,
oil filter runoff, and main bearing cap to cylinder block mating surfaces.
4. If no leaks are detected, pressurize the crankcase as outlined in the, Inspection (Engine oil
Leaks in general).
CAUTION: Do not exceed 20.6 kPa (3 psi).
5. If the leak is not detected, very slowly turn the crankshaft and watch for leakage. If a leak is
detected between the crankshaft and seal while slowly
turning the crankshaft, it is possible the crankshaft seal surface is damaged. The seal area on the
crankshaft could have minor nicks or scratches that can be polished out with emery cloth.
CAUTION: Use extreme caution when crankshaft polishing is necessary to remove minor nicks and
scratches. The crankshaft seal flange is especially machined to complement the function of the
rear oil seal.
6. For bubbles that remain steady with shaft rotation, no further inspection can be done until
disassembled.

STANDARD PROCEDURE - ENGINE OIL SERVICE
The engine oil level indicator is located at the left hand of the engine on the 5.7L engines.
CRANKCASE OIL LEVEL INSPECTION
CAUTION: Do not overfill crankcase with engine oil, pressure loss or oil foaming can result.
Inspect engine oil level approximately every 800 kilometers (500 miles). Unless the engine has
exhibited loss of oil pressure, run the engine for about ten minutes before checking oil level.
Checking engine oil level on a cold engine is not accurate. To ensure proper lubrication of an
engine, the engine oil must be maintained at an acceptable level. The acceptable levels are
indicated between the ADD and SAFE marks on the engine oil dipstick. 1. Position vehicle on level
surface. 2. With engine OFF, allow approximately five minutes for oil to settle to bottom of
crankcase, remove engine oil dipstick. 3. Wipe dipstick clean. 4. Install dipstick and verify it is
seated in the tube. 5. Remove dipstick, with handle held above the tip, take oil level reading. 6. Add
oil only if level is below the ADD mark on dipstick.
ENGINE OIL CHANGE
Change engine oil at mileage and time intervals described in Maintenance Schedules. Run engine
until achieving normal operating temperature. 1. Position the vehicle on a level surface and turn
engine off. 2. Hoist and support vehicle on safety stands. 3. Remove oil fill cap. 4. Place a suitable
drain pan under crankcase drain. 5. Remove drain plug from crankcase and allow oil to drain into
pan. Inspect drain plug threads for stretching or other damage. Replace drain plug if
damaged.
6. Install drain plug in crankcase. Torque to 34 Nm (25 ft. lbs.). 7. Lower vehicle and fill crankcase
with specified type and amount of engine oil described. 8. Install oil fill cap. 9. Start engine and
inspect for leaks.
10. Stop engine and inspect oil level.
USED ENGINE OIL DISPOSAL
Care should be exercised when disposing used engine oil after it has been drained from a vehicle
engine.

Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Gauge >
Component Information > Description and Operation
Oil Pressure Gauge: Description and Operation
An oil pressure gauge is standard equipment on all instrument clusters. The oil pressure gauge is
located in the upper right quadrant of the instrument cluster, above the coolant temperature gauge.
The oil pressure gauge consists of a movable gauge needle or pointer controlled by the instrument
cluster circuitry and a fixed 90 degree scale on the cluster overlay that reads left-to-right from "L"
(or Low) to "H" (or High) for gasoline engines except SRT-10. On SRT-10 models, the scale reads
from "0" kPa to "700" kPa in markets where a metric instrument cluster is specified, or from "0" psi
to "100" psi in all other markets. On vehicles with a diesel engine the scale reads from "0" kPa to
"760" kPa in markets where a metric instrument cluster is specified, or from "0" psi to "110" psi in
all other markets.
An International Control and Display Symbol icon for "Engine Oil" is located on the cluster overlay,
directly below the left end of the gauge scale. On all models except SRT-10 the oil pressure gauge
graphics are black against a white field except for two red graduations at the low end of the gauge
scale. On SRT-10 the gauge graphics are black against a silver field except for a single red zone at
the low end of the gauge scale. In either case, the gauge graphics are clearly visible within the
instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned On, the black graphics appear blue-green and the red graphics still
appear red. The gauge needle has internal optical illumination. Gauge illumination is provided by
replaceable incandescent bulb and holder units located on the instrument cluster electronic circuit
board. The oil pressure gauge is serviced as a unit with the instrument cluster.
The oil pressure gauge gives an indication to the vehicle operator of the engine oil pressure. This
gauge is controlled by the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) on vehicles
with a gasoline engine, or from the Engine Control Module (ECM) on vehicles equipped with a
diesel engine over the Programmable Communications Interface (PCI) data bus.
The oil pressure gauge is an air core magnetic unit that receives battery current on the instrument
cluster electronic circuit board through the fused ignition switch output (run-start) circuit whenever
the ignition switch is in the On or Start positions. The cluster is programmed to move the gauge
needle back to the low end of the scale after the ignition switch is turned to the Off position. The
instrument cluster circuitry controls the gauge needle position and provides the following features:
- Engine Oil Pressure Message - The instrument cluster circuitry restricts the oil pressure gauge
needle operation in order to provide readings that are consistent with customer expectations. For
all models except SRT-10, each time the cluster receives a message from the PCM or ECM
indicating the engine oil pressure is above about 41 kPa (6 psi) the cluster holds the gauge needle
at a point near the middle increment within the normal range on the gauge scale. For SRT-10
models, each time the cluster receives a message from the PCM indicating the engine oil pressure
is above about 41 kPa (6 psi) the cluster moves the gauge needle in a linear fashion to the proper
relative pressure position of the gauge scale.
- Engine Oil Pressure Low Message - Each time the cluster receives three consecutive bus
messages from the PCM or ECM indicating the engine oil pressure is below about 41 kPa (6 psi),
the gauge needle is moved to the red graduations (except SRT-10) or to the red zone (SRT-10) at
the far left end of the gauge scale, the check gauges indicator is illuminated, and a single chime
tone is generated. The gauge needle remains at the left end of the gauge scale and the check
gauges indicator remains illuminated until the cluster receives a message from the PCM or ECM
indicating that the engine oil pressure is above about 41 kPa (6 psi), or until the ignition switch is
turned to the Off position, whichever occurs first. The cluster will only turn the check gauges
indicator on in response to an engine oil pressure low message if the engine speed message is
greater than zero.
- Communication Error - If the cluster fails to receive an engine oil pressure message, it will hold
the gauge needle at the last indication for about ten seconds, or until the ignition switch is turned to
the Off position, whichever occurs first. After ten seconds, the cluster will move the gauge needle to
the low end of the gauge scale.
- Actuator Test - Each time the cluster is put through the actuator test, the oil pressure gauge
needle will be swept to several calibration points on the gauge scale in a prescribed sequence in
order to confirm the functionality of the gauge and the cluster control circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the engine oil pressure sensor to
determine the engine oil pressure. On vehicles with a diesel engine, the ECM continually monitors
the engine oil pressure sensor to determine the engine oil pressure. The PCM or ECM then sends
the proper engine oil pressure messages to the instrument cluster. If the instrument cluster turns on
the check gauges indicator due to a low oil pressure gauge reading, it may indicate that the engine
or the engine oiling system requires service.
For proper diagnosis of the engine oil pressure sensor, the PCM, the ECM, the PCI data bus, or
the electronic message inputs to the instrument cluster that control the oil pressure gauge, a
diagnostic scan tool is required.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Component Information > Diagrams > Diagram Information and Instructions > Page 1675
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Temperature Gauge >
Component Information > Description and Operation
Oil Temperature Gauge: Description and Operation
An oil temperature gauge (1) is standard equipment on all SRT-10 models. This electronic, analog
gauge is located in the lower end of the left A-pillar trim molding below the grab handle (2), in clear
view of the vehicle operator. The gauge dial face is visible through a clear plastic lens, which is
secured to the gauge housing with a silver anodized trim ring. The remainder of the gauge,
including the mounting provisions and the electrical connections, are concealed behind the left
A-pillar trim molding.
The molded plastic housing at the rear of the gauge protects the electronic circuitry of the gauge
and has two mounting studs, which are secured by nuts to a molded plastic mounting bracket
screwed to the back of the A-pillar trim molding. A short pigtail wire with a connector extends from
the back of the gauge housing and connects the gauge to the vehicle electrical system through a
take out and connector of the instrument panel wire harness.
The oil temperature gauge consists of a movable gauge needle or pointer with a 270 degree sweep
that is controlled by the electronic gauge circuitry. The gauge overlay reads left-to-right from "60" to
"150" with "° C" indicated directly below the low (left) end of the scale in markets where a metric
instrument cluster is specified, or from "140" to "300" with "° F" indicated directly below the left end
of the scale for all other markets. The text "OIL TEMP" is imprinted on the center of the gauge
overlay below the hub of the gauge needle, while the text "SRT" is imprinted above the hub of the
gauge needle. The gauge graphics are black against a silver field except for a single red zone at
the high (right) end of the gauge scale and are clearly visible in daylight.
General illumination lighting for the gauge is provided by a Light Emitting Diode (LED) that is
soldered onto the gauge circuit board. The gauge overlay is a laminated plastic unit. The dark,
visible, outer surface of the overlay is marked with the gauge dial face and graduations, but this
layer is also translucent. The underlying layer of the overlay is opaque and allows light from the
LED on the circuit board behind it to be visible through the outer layer of the overlay only through
predetermined stencil-like cutouts. When illuminated from behind by the panel lamps dimmer
controlled gauge lighting with the exterior lamps turned On, the black graphics appear blue-green
and the red graphics still appear red. The gauge needle has internal optical illumination.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Temperature Gauge >
Component Information > Description and Operation > Page 1704
The oil temperature gauge cannot be repaired or adjusted and, if damaged or faulty, it must be
replaced. The gauge illumination LED unit is not available for service replacement and, if damaged
or faulty, the entire gauge must be replaced.
The oil temperature gauge gives an indication to the vehicle operator of the engine oil temperature.
This gauge is controlled by its own internal electronic circuit board based upon a hard wired input
received by the gauge from an oil temperature sensor (4) installed in a tapped hole that penetrates
an oil passage on the right side of the engine block (2) just behind the oil pressure sensor (3).
The oil temperature sensor is a Negative Temperature Coefficient (NTC) thermistor that changes
its internal resistance with changes in temperature. The sensor has two terminals. One terminal
receives a hard wired ground path through a take out and connector of the engine wire harness (1),
and the second terminal provides a variable output to the gauge through the same take out and
connector. As the oil temperature increases the resistance of the sensor decreases, and as the oil
temperature decreases the resistance of the sensor increases.
The oil temperature gauge is an air core magnetic unit. The gauge pigtail wire and connector
provides the gauge electronic circuit board with a hard wired ground path, battery current through a
fused ignition switch output (run-start) circuit, a Pulse Width Modulated (PWM) panel lamps dimmer
input from the instrument cluster for general illumination, and the input from the oil temperature
sensor. This gauge is only operational when the ignition switch is in the On or Start positions. The
gauge electronic circuit board reads the input from the oil temperature sensor, then provides linear
positioning of the gauge needle on the gauge scale based upon that input. The gauge electronics
will move the gauge needle back to the low end of the scale after the ignition switch is turned to the
Off position.
The oil temperature gauge and the oil temperature sensor may be diagnosed using conventional
diagnostic tools and methods.

The hard wired oil temperature gauge and gauge lighting circuits may be diagnosed and tested
using conventional diagnostic tools and procedures. The wiring information includes wiring
diagrams, proper wire and connector repair procedures, details of wire harness routing and
retention, connector pin-out information and location views for the various wire harness connectors,
splices and grounds.
NOTE: When testing the oil temperature gauge by alternately opening and shorting the oil
temperature sensor signal circuit, the gauge pointer may rotate in either direction (clockwise or
counterclockwise) to reach the objective point on the gauge scale. This is a normal condition as the
gauge electronics are programmed to move the pointer from its current position to the objective
position in the direction that provides the shortest pointer travel distance.

> Component Information > Description and Operation
Oil Pressure Gauge: Description and Operation
An oil pressure gauge is standard equipment on all instrument clusters. The oil pressure gauge is
located in the upper right quadrant of the instrument cluster, above the coolant temperature gauge.
The oil pressure gauge consists of a movable gauge needle or pointer controlled by the instrument
cluster circuitry and a fixed 90 degree scale on the cluster overlay that reads left-to-right from "L"
(or Low) to "H" (or High) for gasoline engines except SRT-10. On SRT-10 models, the scale reads
from "0" kPa to "700" kPa in markets where a metric instrument cluster is specified, or from "0" psi
to "100" psi in all other markets. On vehicles with a diesel engine the scale reads from "0" kPa to
"760" kPa in markets where a metric instrument cluster is specified, or from "0" psi to "110" psi in
all other markets.
An International Control and Display Symbol icon for "Engine Oil" is located on the cluster overlay,
directly below the left end of the gauge scale. On all models except SRT-10 the oil pressure gauge
graphics are black against a white field except for two red graduations at the low end of the gauge
scale. On SRT-10 the gauge graphics are black against a silver field except for a single red zone at
the low end of the gauge scale. In either case, the gauge graphics are clearly visible within the
instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned On, the black graphics appear blue-green and the red graphics still
appear red. The gauge needle has internal optical illumination. Gauge illumination is provided by
replaceable incandescent bulb and holder units located on the instrument cluster electronic circuit
board. The oil pressure gauge is serviced as a unit with the instrument cluster.
The oil pressure gauge gives an indication to the vehicle operator of the engine oil pressure. This
gauge is controlled by the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) on vehicles
with a gasoline engine, or from the Engine Control Module (ECM) on vehicles equipped with a
diesel engine over the Programmable Communications Interface (PCI) data bus.
The oil pressure gauge is an air core magnetic unit that receives battery current on the instrument
cluster electronic circuit board through the fused ignition switch output (run-start) circuit whenever
the ignition switch is in the On or Start positions. The cluster is programmed to move the gauge
needle back to the low end of the scale after the ignition switch is turned to the Off position. The
instrument cluster circuitry controls the gauge needle position and provides the following features:
- Engine Oil Pressure Message - The instrument cluster circuitry restricts the oil pressure gauge
needle operation in order to provide readings that are consistent with customer expectations. For
all models except SRT-10, each time the cluster receives a message from the PCM or ECM
indicating the engine oil pressure is above about 41 kPa (6 psi) the cluster holds the gauge needle
at a point near the middle increment within the normal range on the gauge scale. For SRT-10
models, each time the cluster receives a message from the PCM indicating the engine oil pressure
is above about 41 kPa (6 psi) the cluster moves the gauge needle in a linear fashion to the proper
relative pressure position of the gauge scale.
- Engine Oil Pressure Low Message - Each time the cluster receives three consecutive bus
messages from the PCM or ECM indicating the engine oil pressure is below about 41 kPa (6 psi),
the gauge needle is moved to the red graduations (except SRT-10) or to the red zone (SRT-10) at
the far left end of the gauge scale, the check gauges indicator is illuminated, and a single chime
tone is generated. The gauge needle remains at the left end of the gauge scale and the check
gauges indicator remains illuminated until the cluster receives a message from the PCM or ECM
indicating that the engine oil pressure is above about 41 kPa (6 psi), or until the ignition switch is
turned to the Off position, whichever occurs first. The cluster will only turn the check gauges
indicator on in response to an engine oil pressure low message if the engine speed message is
greater than zero.
- Communication Error - If the cluster fails to receive an engine oil pressure message, it will hold
the gauge needle at the last indication for about ten seconds, or until the ignition switch is turned to
the Off position, whichever occurs first. After ten seconds, the cluster will move the gauge needle to
the low end of the gauge scale.
- Actuator Test - Each time the cluster is put through the actuator test, the oil pressure gauge
needle will be swept to several calibration points on the gauge scale in a prescribed sequence in
order to confirm the functionality of the gauge and the cluster control circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the engine oil pressure sensor to
determine the engine oil pressure. On vehicles with a diesel engine, the ECM continually monitors
the engine oil pressure sensor to determine the engine oil pressure. The PCM or ECM then sends
the proper engine oil pressure messages to the instrument cluster. If the instrument cluster turns on
the check gauges indicator due to a low oil pressure gauge reading, it may indicate that the engine
or the engine oiling system requires service.
For proper diagnosis of the engine oil pressure sensor, the PCM, the ECM, the PCI data bus, or
the electronic message inputs to the instrument cluster that control the oil pressure gauge, a
diagnostic scan tool is required.

Oil Temperature Gauge: Description and Operation
An oil temperature gauge (1) is standard equipment on all SRT-10 models. This electronic, analog
gauge is located in the lower end of the left A-pillar trim molding below the grab handle (2), in clear
view of the vehicle operator. The gauge dial face is visible through a clear plastic lens, which is
secured to the gauge housing with a silver anodized trim ring. The remainder of the gauge,
including the mounting provisions and the electrical connections, are concealed behind the left
A-pillar trim molding.
The molded plastic housing at the rear of the gauge protects the electronic circuitry of the gauge
and has two mounting studs, which are secured by nuts to a molded plastic mounting bracket
screwed to the back of the A-pillar trim molding. A short pigtail wire with a connector extends from
the back of the gauge housing and connects the gauge to the vehicle electrical system through a
take out and connector of the instrument panel wire harness.
The oil temperature gauge consists of a movable gauge needle or pointer with a 270 degree sweep
that is controlled by the electronic gauge circuitry. The gauge overlay reads left-to-right from "60" to
"150" with "° C" indicated directly below the low (left) end of the scale in markets where a metric
instrument cluster is specified, or from "140" to "300" with "° F" indicated directly below the left end
of the scale for all other markets. The text "OIL TEMP" is imprinted on the center of the gauge
overlay below the hub of the gauge needle, while the text "SRT" is imprinted above the hub of the
gauge needle. The gauge graphics are black against a silver field except for a single red zone at
the high (right) end of the gauge scale and are clearly visible in daylight.
General illumination lighting for the gauge is provided by a Light Emitting Diode (LED) that is
soldered onto the gauge circuit board. The gauge overlay is a laminated plastic unit. The dark,
visible, outer surface of the overlay is marked with the gauge dial face and graduations, but this
layer is also translucent. The underlying layer of the overlay is opaque and allows light from the
LED on the circuit board behind it to be visible through the outer layer of the overlay only through
predetermined stencil-like cutouts. When illuminated from behind by the panel lamps dimmer
controlled gauge lighting with the exterior lamps turned On, the black graphics appear blue-green
and the red graphics still appear red. The gauge needle has internal optical illumination.

Gauge > Component Information > Description and Operation > Page 1724
The oil temperature gauge cannot be repaired or adjusted and, if damaged or faulty, it must be
replaced. The gauge illumination LED unit is not available for service replacement and, if damaged
or faulty, the entire gauge must be replaced.
The oil temperature gauge gives an indication to the vehicle operator of the engine oil temperature.
This gauge is controlled by its own internal electronic circuit board based upon a hard wired input
received by the gauge from an oil temperature sensor (4) installed in a tapped hole that penetrates
an oil passage on the right side of the engine block (2) just behind the oil pressure sensor (3).
The oil temperature sensor is a Negative Temperature Coefficient (NTC) thermistor that changes
its internal resistance with changes in temperature. The sensor has two terminals. One terminal
receives a hard wired ground path through a take out and connector of the engine wire harness (1),
and the second terminal provides a variable output to the gauge through the same take out and
connector. As the oil temperature increases the resistance of the sensor decreases, and as the oil
temperature decreases the resistance of the sensor increases.
The oil temperature gauge is an air core magnetic unit. The gauge pigtail wire and connector
provides the gauge electronic circuit board with a hard wired ground path, battery current through a
fused ignition switch output (run-start) circuit, a Pulse Width Modulated (PWM) panel lamps dimmer
input from the instrument cluster for general illumination, and the input from the oil temperature
sensor. This gauge is only operational when the ignition switch is in the On or Start positions. The
gauge electronic circuit board reads the input from the oil temperature sensor, then provides linear
positioning of the gauge needle on the gauge scale based upon that input. The gauge electronics
will move the gauge needle back to the low end of the scale after the ignition switch is turned to the
Off position.
The oil temperature gauge and the oil temperature sensor may be diagnosed using conventional
diagnostic tools and methods.

SEAL - CRANKSHAFT OIL - REAR
DIAGNOSIS AND TESTING - REAR SEAL AREA LEAKS
Since it is sometimes difficult to determine the source of an oil leak in the rear seal area of the
engine, a more involved inspection is necessary. The following steps should be followed to help
pinpoint the source of the leak.
If the leakage occurs at the crankshaft rear oil seal area: 1. Disconnect the battery. 2. Raise the
vehicle. 3. Remove torque converter or clutch housing cover and inspect rear of block for evidence
of oil. Use a black light to check for the oil leak:
a. Circular spray pattern generally indicates seal leakage or crankshaft damage. b. Where leakage
tends to run straight down, possible causes are a porous block, camshaft bore cup plugs, oil galley
pipe plugs, oil filter runoff,
and main bearing cap to cylinder block mating surfaces. See Engine, for proper repair procedures
of these items.
4. If no leaks are detected, pressurized the crankcase as outlined in the section, Inspection (Engine
oil Leaks in general)
CAUTION: Do not exceed 20.6 kPa (3 psi).
5. If the leak is not detected, very slowly turn the crankshaft and watch for leakage. If a leak is
detected between the crankshaft and seal while slowly
turning the crankshaft, it is possible the crankshaft seal surface is damaged. The seal area on the
crankshaft could have minor nicks or scratches that can be polished out with emery cloth.
CAUTION: Use extreme caution when crankshaft polishing is necessary to remove minor nicks or
scratches. The crankshaft seal flange is specially machined to complement the function of the rear
oil seal.
6. For bubbles that remain steady with shaft rotation, no further inspection can be done until
disassembled. Refer to - ENGINE - DIAGNOSIS AND
TESTING, under the Oil Leak row, for components inspections on possible causes and corrections.
See: Testing and Inspection/Non-Trouble Code Procedures/Engine Oil Leak Inspection
7. After the oil leak root cause and appropriate corrective action have been identified, Refer to ENGINE/ENGINE BLOCK/CRANKSHAFT OIL

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Sender > Component Information > Diagrams > Diagram Information and Instructions > Page 1747
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Connector views show the connector and the circuits involved with that connector. The connectors
are identified using the name/number on the diagram sheets, and a master list can be found at
Vehicle/Diagrams.
Connector, Ground and Splice Identification and Location
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
Identification
Connectors, grounds, and splices are identified as follows: In-line connectors located in the engine compartment are C100 series numbers
- In-line connectors located in the Instrument Panel area are C200 series numbers.
- In-line connectors located in the body are C300 series numbers.
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Locations
Vehicle/Locations contains the master connector/ground/splice location index charts with
hyperlinks to the applicable location illustrations. The illustrations contain the connector name (or
number)/ground number/splice number and component identification.
The abbreviation T/O is used in the location column to indicate a point in which the wiring harness
branches out to a component. The abbreviation N/S means Not Shown in the illustrations.
PLEASE NOTE: The master location index charts contain numerous items that may not be
applicable to all vehicle models. If a link on the master location index chart to a figure is not
functional, that means that the chart item and/or figure in question does NOT apply to the vehicle
model selected.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Fig.7 Testing For Voltage Potential
STANDARD PROCEDURE - TESTING OF VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

STANDARD PROCEDURE - TESTING FOR A VOLTAGE DROP
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery (Fig. 9).
2. Connect the other lead of the voltmeter to the other side of the switch, component or circuit. 3.
Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Sender > Component Information > Diagrams > Diagram Information and Instructions > Page 1766
- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Ignition Cable: Description and Operation
Spark plug cables are sometimes referred to as secondary ignition wires, or secondary ignition
cables. Plug cables are used only on the 5.7L V-8 engine.
The spark plug cables transfer electrical current from the ignition coil(s) and/or distributor, to
individual spark plugs at each cylinder. The resistive spark plug cables are of nonmetallic
construction. The cables provide suppression of radio frequency emissions from the ignition
system.

Ignition Cable: Service and Repair
REMOVAL
Spark plug cables on the 5.7L engine are paired on cylinders 1/6, 2/3, 4/7 and 5/8. Before
removing or disconnecting any spark plug cables, note their original position. Remove cables
one-at-a-time. To prevent ignition crossfire, spark plug cables MUST be placed in cable tray
(routing loom) into their original position. The cable retention clips must also be securely locked.
Before installing spark plug cables to either the spark plugs or coils, apply dielectric grease to
inside of boots.
If cable tray removal is necessary, release the 4 tray-to-manifold retention clips.
INSTALLATION
Install cables into the proper engine cylinder firing order sequence. Refer to Specifications. When
replacing the spark plug and coil cables, route the cables correctly and secure them in the proper
retainers. Failure to route the cables properly may cause the radio to reproduce ignition noise. It
could also cause cross-ignition of the plugs, or, may short-circuit the cables to ground. When
installing new cables, make sure a positive connection is made. A snap should be felt when a good
connection is made.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

COOLANT
DESCRIPTION
ENGINE COOLANT
WARNING: ANTIFREEZE IS AN ETHYLENE GLYCOL BASE COOLANT AND IS HARMFUL IF
SWALLOWED OR INHALED. IF SWALLOWED, DRINK TWO GLASSES OF WATER AND
INDUCE VOMITING. IF INHALED, MOVE TO FRESH AIR AREA. SEEK MEDICAL ATTENTION
IMMEDIATELY. DO NOT STORE IN OPEN OR UNMARKED CONTAINERS. WASH SKIN AND
CLOTHING THOROUGHLY AFTER COMING IN CONTACT WITH ETHYLENE GLYCOL. KEEP
OUT OF REACH OF CHILDREN. DISPOSE OF GLYCOL BASE COOLANT PROPERLY,
CONTACT YOUR DEALER OR GOVERNMENT AGENCY FOR LOCATION OF COLLECTION
CENTER IN YOUR AREA. DO NOT OPEN A COOLING SYSTEM WHEN THE ENGINE IS AT
OPERATING TEMPERATURE OR HOT UNDER PRESSURE, PERSONAL INJURY CAN
RESULT. AVOID RADIATOR COOLING FAN WHEN ENGINE COMPARTMENT RELATED
SERVICE IS PERFORMED, PERSONAL INJURY CAN RESULT.
ETHYLENE-GLYCOL MIXTURES
CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can
cause problems associated with 100 percent ethylene-glycol.
The use of aluminum cylinder blocks, cylinder heads and water pumps requires special corrosion
protection. Only Mopar(R) Antifreeze/Coolant, 5 year/100,000 Mile Formula (ethylene-glycol base
coolant with corrosion inhibitors called HOAT, for Hybrid Additive Technology) is recommended.
This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water
to obtain a freeze point of -37°C (-35°F).
The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle
operating conditions. The antifreeze concentration must always be a minimum of 44 percent,
year-round in all climates. If percentage is lower than 44 percent, engine parts may be eroded by
cavitation, and cooling system components may be severely damaged by corrosion. Maximum
protection against freezing is provided with a 68% antifreeze concentration, which prevents
freezing down to -67.7° C (-90° F). A higher percentage will freeze at a warmer temperature. Also,
a higher percentage of antifreeze can cause the engine to overheat because the specific heat of
antifreeze is lower than that of water.
Use of 100 percent ethylene-glycol will cause formation of additive deposits in the system, as the
corrosion inhibitive additives in ethylene-glycol require the presence of water to dissolve. The
deposits act as insulation, causing temperatures to rise to as high as 149°C (300°F). This
temperature is hot enough to melt plastic and soften solder. The increased temperature can result
in engine detonation. In addition, 100 percent ethylene-glycol freezes at 22°C (8°F).
PROPYLENE-GLYCOL MIXTURES
It's overall effective temperature range is smaller than that of ethylene-glycol. The freeze point of
50/50 propylene-glycol and water is -32°C (-26°F). 5°C higher than ethylene-glycol's freeze point.
The boiling point (protection against summer boil-over) of propylene-glycol is 125°C (257°F) at 96.5
kPa (14 psi), compared to 128°C (263°F) for ethylene-glycol. Use of propylene-glycol can result in
boil-over or freeze-up on a cooling system designed for ethylene-glycol. Propylene glycol also has
poorer heat transfer characteristics than ethylene glycol. This can increase cylinder head
temperatures under certain conditions.
Propylene-glycol-ethylene-glycol Mixtures can cause the destabilization of various corrosion
inhibitors, causing damage to the various cooling system components. Also, once ethylene-glycol
and propylene-glycol based coolants are mixed in the vehicle, conventional methods of determining
freeze point will not be accurate. Both the refractive index and specific gravity differ between
ethylene glycol and propylene glycol.
OPERATION
Coolant flows through the engine block absorbing the heat from the engine, then flows to the
radiator where the cooling fins in the radiator transfers the heat from the coolant to the atmosphere.
During cold weather the ethylene-glycol or propylene-glycol coolant prevents water present in the
cooling system from freezing within temperatures indicated by mixture ratio of coolant to water.

WARNING: ANTIFREEZE IS AN ETHYLENE-GLYCOL BASE COOLANT AND IS HARMFUL IF
SWALLOWED OR INHALED. IF SWALLOWED, DRINK TWO GLASSES OF WATER AND
INDUCE VOMITING. IF INHALED, MOVE TO FRESH AIR AREA. SEEK MEDICAL ATTENTION
IMMEDIATELY. DO NOT STORE IN OPEN OR UNMARKED CONTAINERS. WASH SKIN AND
CLOTHING THOROUGHLY AFTER COMING IN CONTACT WITH ETHYLENE-GLYCOL. KEEP
OUT OF REACH OF CHILDREN. DISPOSE OF GLYCOL BASE COOLANT PROPERLY,
CONTACT YOUR DEALER OR GOVERNMENT AGENCY FOR LOCATION OF COLLECTION
CENTER IN YOUR AREA. DO NOT OPEN A COOLING SYSTEM WHEN THE ENGINE IS AT
OPERATING TEMPERATURE OR HOT UNDER PRESSURE, PERSONAL INJURY CAN
RESULT. AVOID RADIATOR COOLING FAN WHEN ENGINE COMPARTMENT RELATED
SERVICE IS PERFORMED, PERSONAL INJURY CAN RESULT.
CAUTION: Use of Propylene-Glycol based coolants is not recommended, as they provide less
freeze protection and less corrosion protection.
The cooling system is designed around the coolant. The coolant must accept heat from engine
metal, in the cylinder head area near the exhaust valves and engine block. Then coolant carries the
heat to the radiator where the tube/ fin radiator can transfer the heat to the air.
The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion
protection. Mopar(R) Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the
equivalent ethylene-glycol base coolant with organic corrosion inhibitors (called HOAT, for Hybrid
Organic Additive Technology) is recommended. This coolant offers the best engine cooling without
corrosion when mixed with 50% ethylene-glycol and 50% distilled water to obtain a freeze point of
-37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh
properly mixed coolant solution.
CAUTION: Mopar(R) Antifreeze/Coolant, 5 Year/10O,000 Mile Formula (MS-9769) may not be
mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other
HOAT), may result in engine damage that may not be covered under the new vehicle warranty, and
decreased corrosion protection.
COOLANT PERFORMANCE
The required ethylene-glycol (antifreeze) and water mixture depends upon climate and vehicle
operating conditions. The coolant performance of various mixtures follows:
Pure Water - Water can absorb more heat than a mixture of water and ethylene-glycol. This is for
purpose of heat transfer only. Water also freezes at a higher temperature and allows corrosion.
100 percent Ethylene-Glycol - The corrosion inhibiting additives in ethylene-glycol need the
presence of water to dissolve. Without water, additives form deposits in system. These act as
insulation causing temperature to rise to as high as 149°C (300°F). This temperature is hot enough
to melt plastic and soften solder. The increased temperature can result in engine detonation. In
addition, 100 percent ethylene-glycol freezes at -22°C (-8°F).
50/50 Ethylene-Glycol and Water - Is the recommended mixture, it provides protection against
freezing to -37°C (-34°F). The antifreeze concentration must always be a minimum of 44 percent,
year-round in all climates. If percentage is lower, engine parts may be eroded by cavitation.
Maximum protection against freezing is provided with a 68 percent antifreeze concentration, which
prevents freezing down to --67.7°C (--90°F). A higher percentage will freeze at a warmer
temperature. Also, a higher percentage of antifreeze can cause the engine to overheat because
specific heat of antifreeze is lower than that of water.
CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can
cause problems associated with 100 percent ethylene-glycol.
COOLANT SELECTION AND ADDITIVES
The use of aluminum cylinder blocks, cylinder heads and water pumps requires special corrosion
protection. Only Mopar(R) Antifreeze/Coolant, 5 Year/100,000 Mile Formula (glycol base coolant
with corrosion inhibitors called HOAT, for Hybrid Organic Additive Technology) is recommended.
This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water
to obtain to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain,
flush, and replace with fresh properly mixed coolant solution.
CAUTION: Do not use coolant additives that are claimed to improve engine cooling.
OPERATION
Coolant flows through the engine block absorbing the heat from the engine, then flows to the
radiator where the cooling fins in the radiator transfers the heat from the coolant to the atmosphere.
During cold weather the ethylene-glycol or propylene-glycol coolant prevents water present in the
cooling system from freezing within temperatures indicated by mixture ratio of coolant to water.

Coolant: Testing and Inspection
DIAGNOSIS AND TESTING
COOLANT CONCENTRATION TESTING
Coolant concentration should be checked when any additional coolant was added to system or
after a coolant drain, flush and refill. The coolant mixture offers optimum engine cooling and
protection against corrosion when mixed to a freeze point of -37°C (-34°F) to -46°C (-50°F). The
use of a hydrometer or a refractometer can be used to test coolant concentration.
A hydrometer will test the amount of glycol in a mixture by measuring the specific gravity of the
mixture. The higher the concentration of ethylene glycol, the larger the number of balls that will
float, and higher the freeze protection (up to a maximum of 60% by volume glycol).
A refractometer Tool 8286 will test the amount of glycol in a coolant mixture by measuring the
amount a beam of light bends as it passes through the fluid.
Some coolant manufactures use other types of glycols into their coolant formulations. Propylene
glycol is the most common new coolant. However, propylene glycol based coolants do not provide
the same freezing protection and corrosion protection and is not recommended.
CAUTION: Do not mix types of coolant - corrosion protection will be severely reduced.

CONTAINER-COOLANT RECOVERY-GAS ENGINES
DESCRIPTION
The coolant reserve/overflow tank is mounted on top of the fan shroud, and is made of high
temperature plastic.
OPERATION
The coolant reserve/overflow system works in conjunction with the radiator pressure cap. It utilizes
thermal expansion and contraction of coolant to keep coolant free of trapped air. It provides a
volume for expansion and contraction of coolant. It also provides a convenient and safe method for
checking coolant level and adjusting level at atmospheric pressure. This is done without removing
the radiator pressure cap. The system also provides some reserve coolant to the radiator to cover
minor leaks and evaporation or boiling losses.
As the engine cools, a vacuum is formed in the cooling system of both the radiator and engine.
Coolant will then be drawn from the coolant tank and returned to a proper level in the radiator.

FAN DRIVE VISCOUS
DESCRIPTION
GAS ENGINES
The thermal viscous fan drive is a silicone-fluid- filled coupling used to connect the fan blades to
the water pump shaft. The coupling allows the fan to be driven in a normal manner. This is done at
low engine speeds while limiting the top speed of the fan to a predetermined maximum level at
higher engine speeds.
OPERATION
A thermostatic bimetallic spring coil is located on the front face of the viscous fan drive unit (a
typical viscous unit is shown in. This spring coil reacts to the temperature of the radiator discharge
air. It engages the viscous fan drive for higher fan speed if the air temperature from the radiator
rises above a certain point. Until additional engine cooling is necessary, the fan will remain at a
reduced rpm regardless of engine speed.
Only when sufficient heat is present, will the viscous fan drive engage. This is when the air flowing
through the radiator core causes a reaction to the bimetallic coil. It then increases fan speed to
provide the necessary additional engine cooling.
Once the engine has cooled, the radiator discharge temperature will drop. The bimetallic coil again
reacts and the fan speed is reduced to the previous disengaged speed.

Temperature Gauge > Component Information > Description and Operation
Temperature Gauge: Description and Operation
An engine coolant temperature gauge is standard equipment on all instrument clusters. The engine
coolant temperature gauge is located in the lower right quadrant of the instrument cluster, below
the oil pressure gauge. The engine coolant temperature gauge consists of a movable gauge needle
or pointer controlled by the instrument cluster circuitry and a fixed 90 degree scale on the cluster
overlay that reads left-to-right from "C" (or Cold) to "H" (or Hot) for gasoline engines except
SRT-10. On SRT-10 models, the scale reads from "60"° C to "120"° C in markets where a metric
instrument cluster is specified, or from "140"° F to "260"° F in all other markets. On vehicles with a
diesel engine, the scale reads from "60"° C to "120"° C in markets where a metric instrument
cluster is specified, or from "140"° F to "245"° F in all other markets. An International Control and
Display Symbol icon for "Engine Coolant Temperature" is located on the cluster overlay directly
below the left end of the gauge scale.
On all models except SRT-10 the engine coolant temperature gauge graphics are black against a
white field except for two red graduations at the high end of the gauge scale. On SRT-10 the gauge
graphics are black against a silver field except for a single red zone at the high end of the gauge
scale. In either case, the gauge graphics are clearly visible within the instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned On, the black gauge graphics appear blue-green and the red
graphics still appear red. The gauge needle has internal optical illumination. Gauge illumination is
provided by replaceable incandescent bulb and holder units located on the instrument cluster
electronic circuit board. The engine coolant temperature gauge is serviced as a unit with the
instrument cluster.
The engine coolant temperature gauge gives an indication to the vehicle operator of the engine
coolant temperature. This gauge is controlled by the instrument cluster circuit board based upon
cluster programming and electronic messages received by the cluster from the Powertrain Control
Module (PCM) on vehicles equipped with a gasoline engine, or from the Engine Control Module
(ECM) on vehicles equipped with a diesel engine over the Programmable Communications
Interface (PCI) data bus.
The engine coolant temperature gauge is an air core magnetic unit that receives battery current on
the instrument cluster electronic circuit board through the fused ignition switch output (run-start)
circuit whenever the ignition switch is in the On or Start positions. The cluster is programmed to
move the gauge needle back to the low end of the scale after the ignition switch is turned to the Off
position. The instrument cluster circuitry controls the gauge needle position and provides the
following features:
- Engine Temperature Message - Each time the cluster receives a message from the PCM or ECM
indicating the engine coolant temperature is between the low end of normal [about 54° C (130° F)
for gasoline engines except SRT-10, or about 60° C (140° F) for SRT-10 and diesel engines] and
the high end of normal [about 122° C (252° F) for gasoline engines, about or about 116° C (240° F)
for diesel engines], the gauge needle is moved to the actual relative temperature position on the
gauge scale.
- Engine Temperature Low Message - Each time the cluster receives a message from the PCM or
ECM indicating the engine coolant temperature is below the low end of normal [about 54° C (130°
F) for gasoline engines except SRT-10, or about 60° C (140° F) for SRT-10 and diesel engines],
the gauge needle is held at the graduation on the far left end of the gauge scale. The gauge needle
remains at the left end of the gauge scale until the cluster receives a message from the PCM or
ECM indicating that the engine temperature is above about 54° C (130° F) for gasoline engines
except SRT-10, or about 60° C (140° F) for SRT-10 and diesel engines, or until the ignition switch
is turned to the Off position, whichever occurs first.
- Engine Temperature High Message - Each time the cluster receives three consecutive bus
messages from the PCM or ECM indicating the engine coolant temperature is above about 122° C
(252° F) for gasoline engines, or about 116° C (240° F) for diesel engines, the gauge needle is
moved into the red zone at the far right end of gauge scale, the check gauges indicator is
illuminated, and a single chime tone is sounded. The gauge needle remains in the red zone and
the check gauges indicator remains illuminated until the cluster receives a message from the PCM
or ECM indicating that the engine temperature is below about 122° C (252° F) for gasoline engines,
or about 116° C (240° F) for diesel engines, or until the ignition switch is turned to the Off position,
whichever occurs first. The chime tone feature will only repeat during the same ignition cycle if the
check gauges indicator is cycled off and then on again by the appropriate engine temperature
messages from the PCM or ECM.
- Communication Error - If the cluster fails to receive an engine temperature message, it will hold
the gauge needle at the last indication for about ten seconds, or until the ignition switch is turned to
the Off position, whichever occurs first. After ten seconds, the cluster will move the gauge needle to
the low end of the gauge scale.
- Actuator Test - Each time the cluster is put through the actuator test, the engine coolant
temperature gauge needle will be swept to several calibration points on the gauge scale in a
prescribed sequence in order to confirm the functionality of the gauge and the cluster control
circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the engine coolant temperature
sensor to determine the engine operating temperature. On vehicles with a diesel engine, the ECM
continually monitors the engine coolant temperature sensor to determine the engine operating
temperature. The PCM or ECM then sends the proper engine coolant temperature messages to the
instrument cluster. If the instrument cluster turns on the check gauges indicator due to a high
engine temperature gauge reading, it may indicate that the engine or the engine cooling system
requires service.
For proper diagnosis of the engine coolant temperature sensor, the PCM, the ECM, the PCI data
bus, or the electronic message inputs to the instrument cluster that control the engine coolant
temperature gauge, a diagnostic scan tool is required.

DIAGNOSIS AND TESTING
RADIATOR COOLANT FLOW
Use the following procedure to determine if coolant is flowing through the cooling system. 1. Idle
engine until operating temperature is reached. If the upper radiator hose is warm to the touch, the
thermostat is opening and coolant is flowing
to the radiator.
WARNING: HOT, PRESSURIZED COOLANT CAN CAUSE INJURY BY SCALDING. USING A
RAG TO COVER THE RADIATOR PRESSURE CAP, OPEN RADIATOR CAP SLOWLY TO THE
FIRST STOP. THIS WILL ALLOW ANY BUILT-UP PRESSURE TO VENT TO THE
RESERVE/OVERFLOW TANK. AFTER PRESSURE BUILD-UP HAS BEEN RELEASED,
REMOVE CAP FROM FILLER NECK.
2. Drain a small amount of coolant from the radiator until the ends of the radiator tubes are visible
through the filler neck. Idle the engine at normal
operating temperature. If coolant is flowing past the exposed tubes, the coolant is circulating.

Description and Operation
Radiator Cap: Description and Operation
CAP - RADIATOR PRESSURE
DESCRIPTION
All cooling systems are equipped with a pressure cap. For 5.9L engines, the pressure cap is
located on top of the radiator outlet tank. For all engines, the pressure cap is located on top of the
coolant degas container. The cap releases pressure at some point within a range of 97-to-124 kPa
(14-to-18 psi). The pressure relief point (in pounds) is engraved on top of the cap
The cooling system will operate at pressures slightly above atmospheric pressure. This results in a
higher coolant boiling point allowing increased radiator cooling capacity. The cap contains a
spring-loaded pressure relief valve. This valve opens when system pressure reaches the release
range of 97-to-124 kPa (14-to-18 psi).
A rubber gasket seals the radiator filler neck. This is done to maintain vacuum during coolant
cool-down and to prevent leakage when system is under pressure.
OPERATION
A vent valve in the center of the cap will remain shut as long as the cooling system is pressurized.
As the coolant cools, it contracts and creates a vacuum in the cooling system. This causes the
vacuum valve to open and coolant in the reserve/overflow container to be drawn through the
recovery hose connecting the filler neck and reserve/ overflow container. If the vacuum valve is
stuck shut, or the recovery hose is kinked, radiator hoses will collapse on cool down.

DIAGNOSIS AND TESTING
RADIATOR CAP-TO-FILLER NECK SEAL
The pressure cap upper gasket (seal) pressure relief can be tested by removing overflow hose
from the radiator filler neck tube. Attach the hose of the pressure tester tool 7700 (or equivalent) to
the tube. It will be necessary to disconnect hose from its adapter for the filler neck. Pump air into
radiator. The pressure cap upper gasket should relieve at 69 to 124kPa (10 to 18 psi) and hold
pressure at a minimum of 55 kPa (8 psi).
WARNING: THE WARNING WORDS, "DO NOT OPEN HOT", ON RADIATOR PRESSURE CAP,
ARE A SAFETY PRECAUTION. WHEN HOT, PRESSURE BUILDS UP IN COOLING SYSTEM.
TO PREVENT SCALDING OR INJURY, RADIATOR CAP SHOULD NOT BE REMOVED WHILE
SYSTEM IS HOT AND/OR UNDER PRESSURE.
Do not remove the radiator cap at any time except for the following purposes: ^
Check and adjust antifreeze freeze point.
^ Refill the system with new antifreeze.
^ Conducting service procedures.
^ Checking for vacuum leaks.
WARNING: IF VEHICLE HAS BEEN RUN RECENTLY, WAIT AT LEAST 15 MINUTES BEFORE
REMOVING RADIATOR CAP. WITH A RAG, SQUEEZE RADIATOR UPPER HOSE TO CHECK
IF SYSTEM IS UNDER PRESSURE. PLACE A RAG OVER CAP AND WITHOUT PUSHING CAP
DOWN, ROTATE IT COUNTER-CLOCKWISE TO FIRST STOP. ALLOW FLUID TO ESCAPE
THROUGH THE COOLANT RESERVE/OVERFLOW HOSE INTO RESERVE/OVERFLOW TANK.
SQUEEZE RADIATOR UPPER HOSE TO DETERMINE WHEN PRESSURE HAS BEEN
RELEASED. WHEN COOLANT AND STEAM STOP BEING PUSHED INTO TANK AND SYSTEM

Hold cap at eye level, upside down. If any light can be seen between vent valve and rubber gasket,
replace cap. A replacement cap must be the type designed for a coolant reserve/overflow system
with a completely sealed diaphragm spring and a rubber gasket. This gasket is used to seal to
radiator filler neck top surface. Use of proper cap will allow coolant return to red radiator.

Radiator Cap: Service and Repair
RADIATOR CAP
Remove the cap from the radiator. Be sure that the sealing surfaces are clean. Moisten the rubber
gasket with water and install the cap on the pressure tester 7700 or an equivalent.
Operate the tester pump to bring the pressure to 104 kPa (15 psi) on the gauge. If the pressure cap
fails to hold pressure of at least 97 kPa (14 psi) replace the cap. Refer to the following CAUTION.
The pressure cap may test properly while positioned on tool 7700 (or equivalent). It may not hold
pressure or vacuum when installed on the radiator. If so, inspect the radiator filler neck and radiator
cap's top gasket for damage. Also inspect for dirt or distortion that may prevent the cap from
sealing properly.
CAUTION: Radiator pressure testing tools are very sensitive to small air leaks which will not cause
cooling system problems. A pressure cap that does not have a history of coolant loss should not be
replaced just because it leaks slowly when tested with this tool. Add water to tool. Turn tool upside
down and recheck pressure cap to confirm that cap needs replacement.
CLEANING
Use only a mild soap and water to clean the radiator cap. Using any type of solvent may cause
damage to the seal in the radiator cap.

Temperature Gauge: Description and Operation
An engine coolant temperature gauge is standard equipment on all instrument clusters. The engine
coolant temperature gauge is located in the lower right quadrant of the instrument cluster, below
the oil pressure gauge. The engine coolant temperature gauge consists of a movable gauge needle
or pointer controlled by the instrument cluster circuitry and a fixed 90 degree scale on the cluster
overlay that reads left-to-right from "C" (or Cold) to "H" (or Hot) for gasoline engines except
SRT-10. On SRT-10 models, the scale reads from "60"° C to "120"° C in markets where a metric
instrument cluster is specified, or from "140"° F to "260"° F in all other markets. On vehicles with a
diesel engine, the scale reads from "60"° C to "120"° C in markets where a metric instrument
cluster is specified, or from "140"° F to "245"° F in all other markets. An International Control and
Display Symbol icon for "Engine Coolant Temperature" is located on the cluster overlay directly
below the left end of the gauge scale.
On all models except SRT-10 the engine coolant temperature gauge graphics are black against a
white field except for two red graduations at the high end of the gauge scale. On SRT-10 the gauge
graphics are black against a silver field except for a single red zone at the high end of the gauge
scale. In either case, the gauge graphics are clearly visible within the instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned On, the black gauge graphics appear blue-green and the red
graphics still appear red. The gauge needle has internal optical illumination. Gauge illumination is
provided by replaceable incandescent bulb and holder units located on the instrument cluster
electronic circuit board. The engine coolant temperature gauge is serviced as a unit with the
instrument cluster.
The engine coolant temperature gauge gives an indication to the vehicle operator of the engine
coolant temperature. This gauge is controlled by the instrument cluster circuit board based upon
cluster programming and electronic messages received by the cluster from the Powertrain Control
Module (PCM) on vehicles equipped with a gasoline engine, or from the Engine Control Module
(ECM) on vehicles equipped with a diesel engine over the Programmable Communications
Interface (PCI) data bus.
The engine coolant temperature gauge is an air core magnetic unit that receives battery current on
the instrument cluster electronic circuit board through the fused ignition switch output (run-start)
circuit whenever the ignition switch is in the On or Start positions. The cluster is programmed to
move the gauge needle back to the low end of the scale after the ignition switch is turned to the Off
position. The instrument cluster circuitry controls the gauge needle position and provides the
following features:
- Engine Temperature Message - Each time the cluster receives a message from the PCM or ECM
indicating the engine coolant temperature is between the low end of normal [about 54° C (130° F)
for gasoline engines except SRT-10, or about 60° C (140° F) for SRT-10 and diesel engines] and
the high end of normal [about 122° C (252° F) for gasoline engines, about or about 116° C (240° F)
for diesel engines], the gauge needle is moved to the actual relative temperature position on the
gauge scale.
- Engine Temperature Low Message - Each time the cluster receives a message from the PCM or
ECM indicating the engine coolant temperature is below the low end of normal [about 54° C (130°
F) for gasoline engines except SRT-10, or about 60° C (140° F) for SRT-10 and diesel engines],
the gauge needle is held at the graduation on the far left end of the gauge scale. The gauge needle
remains at the left end of the gauge scale until the cluster receives a message from the PCM or
ECM indicating that the engine temperature is above about 54° C (130° F) for gasoline engines
except SRT-10, or about 60° C (140° F) for SRT-10 and diesel engines, or until the ignition switch
is turned to the Off position, whichever occurs first.
- Engine Temperature High Message - Each time the cluster receives three consecutive bus
messages from the PCM or ECM indicating the engine coolant temperature is above about 122° C
(252° F) for gasoline engines, or about 116° C (240° F) for diesel engines, the gauge needle is
moved into the red zone at the far right end of gauge scale, the check gauges indicator is
illuminated, and a single chime tone is sounded. The gauge needle remains in the red zone and
the check gauges indicator remains illuminated until the cluster receives a message from the PCM
or ECM indicating that the engine temperature is below about 122° C (252° F) for gasoline engines,
or about 116° C (240° F) for diesel engines, or until the ignition switch is turned to the Off position,
whichever occurs first. The chime tone feature will only repeat during the same ignition cycle if the
check gauges indicator is cycled off and then on again by the appropriate engine temperature
messages from the PCM or ECM.
- Communication Error - If the cluster fails to receive an engine temperature message, it will hold
the gauge needle at the last indication for about ten seconds, or until the ignition switch is turned to
the Off position, whichever occurs first. After ten seconds, the cluster will move the gauge needle to
the low end of the gauge scale.
- Actuator Test - Each time the cluster is put through the actuator test, the engine coolant
temperature gauge needle will be swept to several calibration points on the gauge scale in a
prescribed sequence in order to confirm the functionality of the gauge and the cluster control
circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the engine coolant temperature
sensor to determine the engine operating temperature. On vehicles with a diesel engine, the ECM
continually monitors the engine coolant temperature sensor to determine the engine operating
temperature. The PCM or ECM then sends the proper engine coolant temperature messages to the
instrument cluster. If the instrument cluster turns on the check gauges indicator due to a high
engine temperature gauge reading, it may indicate that the engine or the engine cooling system
requires service.
For proper diagnosis of the engine coolant temperature sensor, the PCM, the ECM, the PCI data
bus, or the electronic message inputs to the instrument cluster that control the engine coolant
temperature gauge, a diagnostic scan tool is required.

Thermostat: Description and Operation
THERMOSTAT - ENGINE COOLANT
DESCRIPTION
GAS ENGINE
CAUTION: Do not operate the engine without a thermostat, except for servicing or testing.
The 3.7L/4.7L/5.7L engines use a pellet-type thermostat that controls the operating temperature of
the engine by controlling the amount of coolant flow to the radiator. The 8.3L engine uses a
movable sleeve type thermostat. On all engines the thermostat is closed below 195°F (90°C).
Above this temperature, coolant is allowed to flow to the radiator. This provides quick engine warm
up and overall temperature control.
Coolant leakage into the pellet container will cause the thermostat to fail in the open position.
Thermostats very rarely stick. Do not attempt to free a thermostat with a prying device.
On the 3.7L/4.7L engine the thermostat is designed to block the flow of the coolant bypass journal
by 50% instead of completely blocking the flow.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Thermostat, Engine Cooling > Component
Information > Specifications > Page 1918
This design controls coolant temperature more accurately.
The same thermostat is used for winter and summer seasons. An engine should not be operated
without a thermostat, except for servicing or testing. Operating without a thermostat causes other
problems. These are: longer engine warm-up time, unreliable warm-up performance, increased
exhaust emissions and crankcase condensation. This condensation can result in sludge formation.
OPERATION
3.7L/4.7L/5.7L Engines The wax pellet is located in a sealed container at the spring end of the
thermostat. When heated, the pellet expands, overcoming closing spring tension and water pump
pressure to force the valve to open.

components. Refer to On-Board Diagnostics (OBD) for additional information. See: Testing and
Inspection/Symptom Related Diagnostic Procedures/Description of On-Board Diagnostics If the
Powertrain Control Module (PCM) detects low engine coolant temperature, it will record a
Diagnostic Trouble Code (DTC) in the PCM memory. Do not change a thermostat for lack of heat
as indicated by the instrument panel gauge or by poor heater performance unless a DTC is
present.
The DTC can also be accessed through the DRBIII (R) scan tool. Refer to the appropriate
Powertrain Diagnostic Procedures information for diagnostic information and operation of the
DRBIII (R) scan tool.

Catalytic Converter: Description and Operation
CONVERTER - CATALYTIC
DESCRIPTION
WARNING: THE NORMAL OPERATING TEMPERATURE OF THE EXHAUST SYSTEM IS VERY
HIGH. THEREFORE, NEVER WORK AROUND OR ATTEMPT TO SERVICE ANY PART OF THE
EXHAUST SYSTEM UNTIL IT IS COOLED. SPECIAL CARE SHOULD BE TAKEN WHEN
WORKING NEAR THE CATALYTIC CONVERTER. THE TEMPERATURE OF THE CONVERTER
RISES TO A HIGH LEVEL AFTER A SHORT PERIOD OF ENGINE OPERATION TIME.
CAUTION: DO NOT remove spark plug wires from plugs or by any other means short out cylinders.
Failure of the catalytic converter can occur due to a temperature increase caused by unburned fuel
passing through the converter.
The stainless steel catalytic converter body is designed to last the life of the vehicle. Excessive
heat can result in bulging or other distortion, but excessive heat will not be the fault of the
converter. If unburned fuel enters the converter, overheating may occur. If a converter is
heat-damaged, correct the cause of the damage at the same time the converter is replaced. Also,
inspect all other components of the exhaust system for heat damage.
Unleaded gasoline must be used to avoid contaminating the catalyst core.
50 State emission vehicles incorporate two mini catalytic converters located after the exhaust
manifolds and before the inline catalytic converter.
OPERATION
The catalytic converter captures and burns any unburned fuel mixture exiting the combustion
chambers during the exhaust stroke of the engine. This process aids in reducing emissions output.

The hard wired chime warning system inputs to the ElectroMechanical Instrument Cluster (EMIC),
as well as other hard wired circuits for this system may be diagnosed and tested using
conventional diagnostic tools and methods. The wiring information includes wiring diagrams, proper
wire and connector repair procedures, details of wire harness routing and retention, connector
pin-out information and location views for the various wire harness connectors, splices and
grounds.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the EMIC,
the Programmable Communications Interface (PCI) data bus, or the electronic message inputs
used by the EMIC to provide chime warning system service. The most reliable, efficient, and
accurate means to diagnose the EMIC, the PCI data bus, and the electronic message inputs for the

A/C Status Indicator Flashing
A/C STATUS INDICATOR FLASHING
Theory of Operation
Running the AC Cooldown test will cause the A/C status indicator to flash. If the test fails, the
status indicator will continue to flash until either the test returns passed or the ignition key is cycled.
When the A/C status indicator is flashing, it will not indicate A/C operating status. However, the A/C
mode switch will continue to function normally. For vehicles equipped with EBL, when the A/C
status indicator is flashing, the EBL status indicator will not function. However, the EBL mode
switch will continue to function normally.
POSSIBLE CAUSES
- A/C Cooldown test failed
1. PERFORM THE A/C COOLDOWN TEST
NOTE: The following are prerequisites of the Cooldown Test. Verify each of the following before
running the test:
- Verify that no Evaporator Temperature Sensor related DTCs are not active. If active, diagnose
and repair the DTC before proceeding.
- Verify that the refrigerant system has an adequate charge. Check and repair as necessary before
proceeding.
- Verify that the blower motor operates correctly in all speeds. Diagnose and repair all blower
related faults before proceeding.
- Verify that the work area ambient temperature is above 21.1° C (70° F) before proceeding. Move
the vehicle to a warmer work area if necessary.
- Verify that the evaporator temperature is above 12.7° C (55° F) before proceeding.
- Verify that the Mode Select control is set to the panel position.
- Verify that the A/C compressor is not running. If the compressor is running, turn the A/C off and
allow the evaporator to warm up before proceeding.

Actuator Circuit Test Diagnostics (Single-Zone)
Theory of Operation
By running the Actuator Circuit Test, the A/C Heater Control can identify up to three door driver
circuits shorted simultaneously. A Short Too Complex fault will set if more than three door driver
circuits are shorted in the same direction (e.g. four door driver circuits all shorted to ground) or if
two or more door driver circuits are shorted with at least one door driver circuit shorted to ignition
and one door driver circuit shorted to ground. Fault messages displaying XXX Driver/Circuit
Shorted to Ignition/Battery and XXX Driver/Circuit Shorted to Ground will set on a per-driver basis.
Fault messages displaying the same two drivers/circuits shorted to ignition/battery as-well-as
shorted to ground indicates that two actuator driver circuits are

NOTE:
Refer to the table for specific applications.
DISCUSSION:
Mopar(R) is currently phasing out pre-programmed PCMs for the vehicles listed. New modules will
no longer be pre-programmed when received from Mopar(R). Replacement of future PCMs will
require programming utilizing the DRBIII(R) and TechCONNECT. The PCM will not operate the
engine until it is programmed. A Diagnostic Trouble Code (DTC) will be set - "not programmed".
CAUTION:
Extreme care must be taken when programming a calibration into a generic PCM. Do not randomly
select a calibration. Once a calibration is selected and programmed, the controller cannot be
reprogrammed to a different calibration. The module can only be reprogrammed to a more recent
version of that calibration.

PARTS REQUIRED:
SPECIAL TOOLS/EQUIPMENT REQUIRED:
NOTE:
An updated J1962 cable has been released. This cable has a red colored connector at the
DRBIII(R) connection. Use this cable whenever a flash is being performed.
REPAIR PROCEDURE:
NOTE:
When flashing a 2002 - 2004 LH vehicle the BCM may need to be disconnected if experiencing
failures during the flash of the transmission portion of the PCM. The BCM will need to be
disconnected after the module ID portion of the flash is complete. Before pressing Page Forward to
begin the flash of the PCM Turn the Key to the OFF position and disconnect the BCM. Then turn
the KEY to the RUN position and Press Page Forward to begin the PCM flash session.
NOTE:
If vehicle is a DAKOTA, then the ABS CAB module connector MUST be disconnected prior to
performing this Repair Procedure. The CAB module and the PCM are connected at the same
diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB
module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is
complete turn the ignition switch to the OFF position, connect the CAB module connector, and then
check for any erroneous DTC's. If the PCM becomes "locked" during reprogramming because the
ABS CAB module connector was not disconnected, then the PCM may be recovered by following
the procedure in this NOTE.
NOTE:
Whenever a controller is programmed, the software in the DRBIII(R); must be programmed with the
latest revision level available.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted and then follow the
directions on the DRBIII(R).
1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from
the DRBIII(R) memory. To clear the memory from the MAIN MENU power up the DRBIII(R) and
then:
a. Simultaneously press the "MORE" and "YES" keys.
b. A screen will appear requesting a "COLD BOOT".
c. Follow the on screen instructions by selecting the "F4" key.

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.
2007 GRAND CHEROKEE W/ 3.0L TD/2005 - 2007 LIBERTY w/2.8L TD/2007 RAM TRUCK/RAM

NOTE:
Refer to the table for specific applications.
DISCUSSION:
Mopar(R) is currently phasing out pre-programmed PCMs for the vehicles listed. New modules will
no longer be pre-programmed when received from Mopar(R). Replacement of future PCMs will
require programming utilizing the DRBIII(R) and TechCONNECT. The PCM will not operate the
engine until it is programmed. A Diagnostic Trouble Code (DTC) will be set - "not programmed".
CAUTION:
Extreme care must be taken when programming a calibration into a generic PCM. Do not randomly
select a calibration. Once a calibration is selected and programmed, the controller cannot be
reprogrammed to a different calibration. The module can only be reprogrammed to a more recent
version of that calibration.

PARTS REQUIRED:
SPECIAL TOOLS/EQUIPMENT REQUIRED:
NOTE:
An updated J1962 cable has been released. This cable has a red colored connector at the
DRBIII(R) connection. Use this cable whenever a flash is being performed.
REPAIR PROCEDURE:
NOTE:
When flashing a 2002 - 2004 LH vehicle the BCM may need to be disconnected if experiencing
failures during the flash of the transmission portion of the PCM. The BCM will need to be
disconnected after the module ID portion of the flash is complete. Before pressing Page Forward to
begin the flash of the PCM Turn the Key to the OFF position and disconnect the BCM. Then turn
the KEY to the RUN position and Press Page Forward to begin the PCM flash session.
NOTE:
If vehicle is a DAKOTA, then the ABS CAB module connector MUST be disconnected prior to
performing this Repair Procedure. The CAB module and the PCM are connected at the same
diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB
module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is
complete turn the ignition switch to the OFF position, connect the CAB module connector, and then
check for any erroneous DTC's. If the PCM becomes "locked" during reprogramming because the
ABS CAB module connector was not disconnected, then the PCM may be recovered by following
the procedure in this NOTE.
NOTE:
Whenever a controller is programmed, the software in the DRBIII(R); must be programmed with the
latest revision level available.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted and then follow the
directions on the DRBIII(R).
1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from
the DRBIII(R) memory. To clear the memory from the MAIN MENU power up the DRBIII(R) and
then:
a. Simultaneously press the "MORE" and "YES" keys.
b. A screen will appear requesting a "COLD BOOT".
c. Follow the on screen instructions by selecting the "F4" key.
d. When the DRB III(R) reboots to the MAIN MENU, proceed to Step 2.

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.
2007 GRAND CHEROKEE W/ 3.0L TD/2005 - 2007 LIBERTY w/2.8L TD/2007 RAM TRUCK/RAM
CAB CHASSIS w 6.7L TD AND 2004-2006 SPRINTER w 2.7L TD ENGINES.
For the above models equipped with Turbo Diesel Engines, the fuel injector "Quantity Values" must
be physically read from each injector and the values written to the ECU with an appropriate scan
tool.

Engine Control Module: Description and Operation PCM
The Powertrain Control Module (PCM) is located in the right-rear section of the engine
compartment under the cowl.
Two different PCM's are used (JTEC and NGC). These can be easily identified. JTEC's use three
32-way connectors, NGC's use four 38-way connectors.
The PCM operates the fuel system. The PCM is a pre-programmed, triple microprocessor digital
computer. It regulates ignition timing, air-fuel ratio, emission control devices, charging system,
certain transmission features, speed control, air conditioning compressor clutch engagement and
idle speed. The PCM can adapt its programming to meet changing operating conditions.
The PCM receives input signals from various switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operations through different system components. These
components are referred to as Powertrain Control Module (PCM) Outputs. The sensors and
switches that provide inputs to the PCM are considered Powertrain Control Module (PCM) Inputs.
The PCM adjusts ignition timing based upon inputs it receives from sensors that react to: engine
rpm, manifold absolute pressure, engine coolant temperature, throttle position, transmission gear
selection (automatic transmission), vehicle speed, power steering pump pressure, and the brake
switch.
The PCM adjusts idle speed based on inputs it receives from sensors that react to: throttle position,
vehicle speed, transmission gear selection, engine coolant temperature and from inputs it receives
from the air conditioning clutch switch and brake switch.
Based on inputs that it receives, the PCM adjusts ignition coil dwell. The PCM also adjusts the
generator charge rate through control of the generator field and provides speed control operation.

Engine Control Module: Description and Operation Modes of Operation
As input signals to the Powertrain Control Module (PCM) change, the PCM adjusts its response to
the output devices. For example, the PCM must calculate different injector pulse width and ignition
timing for idle than it does for wide open throttle (WOT).
The PCM will operate in two different modes: Open Loop and Closed Loop.
During Open Loop modes, the PCM receives input signals and responds only according to preset
PCM programming. Input from the oxygen (02S) sensors is not monitored during Open Loop
modes.
During Closed Loop modes, the PCM will monitor the oxygen (02S) sensors input. This input
indicates to the PCM whether or not the calculated injector pulse width results in the ideal air-fuel
ratio. This ratio is 14.7 parts air-to-1 part fuel. By monitoring the exhaust oxygen content through
the 02S sensor, the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance.
The fuel injection system has the following modes of operation:
- Ignition switch ON
- Engine start-up (crank)
- Engine warm-up
- Idle
- Cruise
- Acceleration
- Deceleration
- Wide open throttle (WOT)
- Ignition switch OFF
The ignition switch On, engine start-up (crank), engine warm-up, acceleration, deceleration and
wide open throttle modes are Open Loop modes. The idle and cruise modes, (with the engine at
operating temperature) are Closed Loop modes.
IGNITION SWITCH (KEY-ON) MODE
This is an Open Loop mode. When the fuel system is activated by the ignition switch, the following
actions occur:
- The PCM pre-positions the idle air control (IAC) motor.
- The PCM determines atmospheric air pressure from the MAP sensor input to determine basic fuel
strategy.
- The PCM monitors the engine coolant temperature sensor input. The PCM modifies fuel strategy
based on this input.
- Intake manifold air temperature sensor input is monitored.
- Throttle position sensor (TPS) is monitored.
- The auto shutdown (ASD) relay is energized by the PCM for approximately three seconds.
- The fuel pump is energized through the fuel pump relay by the PCM. The fuel pump will operate
for approximately three seconds unless the engine is operating or the starter motor is engaged.
- The 02S sensor heater element is energized via the ASD or 02S heater relay. The 02S sensor
input is not used by the PCM to calibrate air-fuel ratio during this mode of operation.
ENGINE START-UP MODE
This is an Open Loop mode. The following actions occur when the starter motor is engaged. The
PCM receives inputs from:
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
The PCM monitors the crankshaft position sensor. If the PCM does not receive a crankshaft
position sensor signal within 3 seconds of cranking the engine, it will shut down the fuel injection
system.
The fuel pump is activated by the PCM through the fuel pump relay.
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
The PCM determines the proper ignition timing according to input received from the crankshaft
position sensor.
ENGINE WARM-UP MODE

injector on and off.
- The PCM adjusts engine idle speed through the idle air control (IAC) motor and adjusts ignition
timing.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
- When engine has reached operating temperature, the PCM will begin monitoring 02S sensor
input. The system will then leave the warm-up mode and go into closed loop operation.
IDLE MODE
When the engine is at operating temperature, this is a Closed Loop mode. At idle speed, the PCM
receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)

ACCELERATION MODE
This is an Open Loop mode. The PCM recognizes an abrupt increase in throttle position or MAP
pressure as a demand for increased engine output and vehicle acceleration. The PCM increases
injector pulse width in response to increased throttle opening.

If the vehicle is under hard deceleration with the proper rpm and closed throttle conditions, the
PCM will ignore the oxygen sensor input signal. The PCM will enter a fuel cut-off strategy in which
it will not supply a ground to the injectors. If a hard deceleration does not exist, the PCM will
determine the proper injector pulse width and continue injection.
Based on the above inputs, the PCM will adjust engine idle speed through the idle air control (IAC)
motor. The PCM adjusts ignition timing by turning the ground path to the coil on and off.

Engine Control Module: Description and Operation Ignition Circuit Sense
This circuit ties the ignition switch to the Powertrain Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage on the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.

the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off. The PCM ignores the oxygen sensor input signal and provides a predetermined
amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
IGNITION SWITCH OFF MODE
When ignition switch is turned to OFF position, the PCM stops operating the injectors, ignition coil,
ASD relay and fuel pump relay.
5 Volt Supplies
Two different Powertrain Control Module (PCM) five volt supply circuits are used; primary and
secondary.
Primary 5-volt supply:
- supplies the required 5 volt power source to the Crankshaft Position (CKP) sensor.
- supplies the required 5 volt power source to the Camshaft Position (CMP) sensor.
- supplies a reference voltage for the Manifold Absolute Pressure (MAP) sensor.
- supplies a reference voltage for the Throttle Position Sensor (TPS) sensor.
Secondary 5-volt supply:
- supplies the required 5 volt power source to the oil pressure sensor.
- supplies the required 5 volt power source for the Vehicle Speed Sensor (VSS) (if equipped).
- supplies the 5 volt power source to the transmission pressure sensor (certain automatic
transmissions).
Ignition Circuit Sense
This circuit ties the ignition switch to the Powertrain Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage on the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.
Power Grounds
The Powertrain Control Module (PCM) has 2 main grounds. Both of these grounds are referred to
as power grounds. All of the high-current, noisy, electrical devices are connected to these grounds
as well as all of the sensor returns. The sensor return comes into the sensor return circuit, passes
through noise suppression, and is then connected to the power ground.
The power ground is used to control ground circuits for the following PCM loads:
- Generator field winding
- Fuel injectors
- Ignition coil(s)
- Certain relays/solenoids
- Certain sensors
Sensor Return
The Sensor Return circuits are internal to the Powertrain Control Module (PCM).
Sensor Return provides a low-noise ground reference for all engine control system sensors.

Engine Control Module: Service and Repair PCM/ECM/SKIM Programming
NOTE: Before replacing the Powertrain Control Module (PCM) or Engine Control Module (ECM),
be certain to check the related component/circuit integrity for failures not detected due to a double
fault in the circuit. Most PCM/ECM driver/control circuit failures are caused by internal component
failures (i.e. relays and solenoids) and shorted circuits (i.e. pull-ups, drivers, and switched circuits).
These failures are difficult to detect when a double fault has occurred and only one DTC has been
set.
When a Powertrain Control Module (PCM) for a gasoline engine, or a Engine Control Module for a
diesel engine and the Sentry Key Immobilizer Module (SKIM) on vehicles equipped with the Sentry
Key Immobilizer System (SKIS) are replaced at the same time, perform the following steps in order:
1. Program the new PCM/ECM. 2. Program the new SKIM. 3. Replace all ignition keys and
program them into the new SKIM.

Engine Control Module: Service and Repair Programming the PCM/ECM/SKIM
The SKIS Secret Key is an ID code that is unique to each SKIM. This code is programmed and
stored in the SKIM, the PCM/ECM, and each ignition key transponder chip. When the PCM/ECM or
SKIM is replaced, it is necessary to program the Secret Key into the new modules using a
diagnostic scan tool. Follow the programming steps outlined in the diagnostic scan tool menu for
the module being replaced as appropriate.
NOTE:
- Be certain to enter the correct country code for the SKIM. If the incorrect country code is
programmed into the SKIM, it cannot be changed and the SKIM must be replaced.
- If the PCM/ECM and the SKIM are replaced at the same time, all vehicle ignition keys will need to
be replaced and the new keys programmed into the new SKIM.
- Programming the PCM/ECM or SKIM is done using a diagnostic scan tool and a PIN to enter
secure access mode. If three attempts are made to enter secure access mode using an incorrect
PIN, secure access mode will be locked out for one hour. To exit this lockout mode, turn the
ignition to the RUN position for one hour then enter the correct PIN. (Ensure all accessories are
turned OFF. Also monitor the battery state and connect a battery charger if necessary).

Engine Control Module: Service and Repair Programming Ignition Keys to the SKIM
Each ignition key transponder also has a unique ID code that is assigned at the time the key is
manufactured. When a key is programmed into the SKIM, the transponder ID code is learned by
the module and the transponder acquires the unique Secret Key ID code from the SKIM. To
program ignition keys into the SKIM, follow the programming steps outlined in the diagnostic scan
tool for "Program Ignition Keys or Key FOBs" under the "SKIM" menu item.
NOTE: A maximum of eight keys can be learned to each SKIM. Once a key is learned to a SKIM,
that key has acquired the Secret Key for that SKIM and cannot be transferred to any other SKIM or
vehicle.
If ignition key programming is unsuccessful, the scan tool will display one of the following error
messages:
- Programming Not Attempted - The scan tool attempts to read the programmed key status and
there are no keys programmed into SKIM memory.
- Programming Key Failed (Possible Used Key From Wrong Vehicle) - SKIM is unable to program
an ignition key transponder due to one of the following: The ignition key transponder is faulty.
- The ignition key transponder is or has been already programmed to another vehicle.
- 8 Keys Already Learned, Programming Not Done - The SKIM transponder ID memory is full.
- Learned Key In Ignition - The ID for the ignition key transponder currently in the ignition lock
cylinder is already programmed into SKIM memory.

Engine Control Module: Service and Repair Module - Powertrain Control
CAUTION:
- Certain ABS systems rely on having the Powertrain Control Module (PCM) broadcast the Vehicle
Identification Number (VIN) over the bus network. To prevent problems of DTCs and other items
related to the VIN broadcast, it is recommend that you disconnect the ABS CAB (controller)
temporarily when replacing the PCM. Once the PCM is replaced, write the VIN to the PCM using
the DRB scan tool. This is done from the engine main menu. Arrow over to the second page to "1.
Miscellaneous". Select "Check VIN" from the choices. Make sure it has the correct VIN entered
before continuing. When the VIN is complete, turn off the ignition key and reconnect the ABS
module connector. This will prevent the setting of DTCs and other items associated with the lack of
a VIN detected when you turn the key ON after replacing the PCM.
- Use the DRB scan tool to reprogram the new PCM with the vehicles original identification number
(VIN) and the vehicles original mileage. If this step is not done, a Diagnostic Trouble Code (DTC)
may be set.
REMOVAL
The PCM (1) is located in the engine compartment attached to the dash panel (3).
To avoid possible voltage spike damage to the PCM, ignition key must be off, and negative battery
cable must be disconnected before unplugging PCM connectors.

Main Relay (Computer/Fuel System): Description and Operation PCM Output
The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power Distribution Center
(PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit on and off.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if:
- the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.

Main Relay (Computer/Fuel System): Description and Operation ASD Sense - PCM Input
A 12 volt signal at this input indicates to the PCM that the ASD has been activated. The relay is
used to connect the oxygen sensor heater element, ignition coil and fuel injectors to 12 volt +
power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Main Relay (Computer/Fuel System): Testing and Inspection
ASD AND FUEL PUMP RELAYS
The following description of operation and tests apply only to the Automatic Shutdown (ASD) and
fuel pump relays. The terminals on the bottom of each relay are numbered. Two different types of
relays may be used, or.
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays,
terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to
terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the
circuit. Terminal 87A is the center terminal on the relay.
- When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30.
This is the On position. Terminal 87 supplies voltage to the rest of the circuit.
The following procedure applies to the ASD and fuel pump relays.
1. Remove relay from connector before testing. 2. With the relay removed from the vehicle, use an
ohmmeter to check the resistance between terminals 85 and 86. The resistance should be 75
ohms
+/- 5 ohms.
3. Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity
between terminals 30 and 87A. 4. Connect the ohmmeter between terminals 87 and 30. The
ohmmeter should not show continuity at this time. 5. Connect one end of a jumper wire (16 gauge
or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12
volt power source.
6. Connect one end of another jumper wire (16 gauge or smaller) to the power side of the 12 volt
power source. Do not attach the other end of the
jumper wire to the relay at this time.
WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS
TEST. DAMAGE TO OHMMETER MAY RESULT.
7. Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The
ohmmeter should now show continuity between relay
terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and
30.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Modules - Fuel Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information
and Instructions > Page 2217
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Fuel Pump Relay: Description and Operation
The 5-pin, 12-volt, fuel pump relay is located in the Power Distribution Center (PDC). Refer to the
label on the PDC cover for relay location.
The Powertrain Control Module (PCM) energizes the electric fuel pump through the fuel pump
relay. The fuel pump relay is energized by first applying battery voltage to it when the ignition key is
turned ON, and then applying a ground signal to the relay from the PCM.
Whenever the ignition key is turned ON, the electric fuel pump will operate. But, the PCM will
shut-down the ground circuit to the fuel pump relay in approximately 1 - 3 seconds unless the
engine is operating or the starter motor is engaged.

Main Relay (Computer/Fuel System): Description and Operation PCM Output
The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power Distribution Center
(PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit on and off.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if:
- the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.

Main Relay (Computer/Fuel System): Description and Operation ASD Sense - PCM Input
A 12 volt signal at this input indicates to the PCM that the ASD has been activated. The relay is
used to connect the oxygen sensor heater element, ignition coil and fuel injectors to 12 volt +
power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Main Relay (Computer/Fuel System): Testing and Inspection
ASD AND FUEL PUMP RELAYS
The following description of operation and tests apply only to the Automatic Shutdown (ASD) and
fuel pump relays. The terminals on the bottom of each relay are numbered. Two different types of
relays may be used, or.
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays,
terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to
terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the
circuit. Terminal 87A is the center terminal on the relay.
- When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30.
This is the On position. Terminal 87 supplies voltage to the rest of the circuit.
The following procedure applies to the ASD and fuel pump relays.
1. Remove relay from connector before testing. 2. With the relay removed from the vehicle, use an
ohmmeter to check the resistance between terminals 85 and 86. The resistance should be 75
ohms
+/- 5 ohms.
3. Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity
between terminals 30 and 87A. 4. Connect the ohmmeter between terminals 87 and 30. The
ohmmeter should not show continuity at this time. 5. Connect one end of a jumper wire (16 gauge
or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12
volt power source.
6. Connect one end of another jumper wire (16 gauge or smaller) to the power side of the 12 volt
power source. Do not attach the other end of the
jumper wire to the relay at this time.
WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS
TEST. DAMAGE TO OHMMETER MAY RESULT.
7. Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The
ohmmeter should now show continuity between relay
terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and
30.

Ignition Relay: Description and Operation
The ignition system is controlled by the Powertrain Control Module (PCM) on all engines.
The 5.7L V-8 engine is equipped with 16 spark plugs. Two plugs are used for each cylinder. The
5.7L is also equipped with 8 separate and independent ignition coils. The one-piece coil bolts
directly to the cylinder head cover and attaches the coils secondary output terminal directly to a
spark plug using a rubber boot seal. Each coil is also equipped with a second output terminal. This
second terminal connects a conventional spark plug cable directly to a spark plug on the opposite
cylinder bank. A separate primary electrical connector is used for each coil.
Eight conventional spark plug cables are used with the 5.7L. These cables connect a coil on one
cylinder bank, directly to a spark plug on the opposite cylinder bank. The cables are placed and
routed in a special plastic loom to keep them separated. This loom is clipped to the intake manifold.
To prevent a miss-match of cables, a corresponding spark plug/coil number is displayed on each
plug cable: 1/6, 2/3, 4/7 and 5/8. These numbers can also be found on the top of the intake
manifold to the right of the throttle body.
Two knock sensors (one for each cylinder bank) are used to help control spark knock. The 5.7L
engine will not use a conventional distributor.
The ignition system consists of:
- 16 Spark Plugs (2 per cylinder)
- 8 Separate, Dual-Secondary Output, Ignition Coils
- 2 knock Sensors
- 8 Secondary Ignition Cables
- Powertrain Control Module (PCM)
- Also to be considered part of the ignition system are certain inputs from the Crankshaft Position,
Camshaft Position, Throttle Position, 2 knock and MAP Sensors

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM (ECM Diesel) to
vary the battery charging rate. System voltage will be higher at colder temperatures and is
gradually reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20° F.

The Camshaft Position Sensor (CMP) on the 5.7L V-8 engine is located below the generator on the
timing chain/case cover on the right/front side of engine.
The CMP sensor is used in conjunction with the crankshaft position sensor to differentiate between
fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective
cylinders. The sensor generates electrical pulses. These pulses (signals) are sent to the Powertrain
Control Module (PCM). The PCM will then determine crankshaft position from both the camshaft
position sensor and crankshaft position sensor.
The tonewheel (2) is located at the front of the camshaft. As the tonewheel rotates, notches (3)
pass through the sync signal generator.
When the cam gear is rotating, the sensor will detect the notches. Input voltage from the sensor to
the PCM will then switch from a low (approximately 0.3 volts) to a high (approximately 5 volts).
When the sensor detects a notch has passed, the input voltage switches back low to approximately
0.3 volts.

Crankshaft Position Sensor: Description and Operation
The Crankshaft Position (CKP) (4) sensor is mounted into the right rear side of the cylinder block. It
is positioned and bolted into a machined hole.
Engine speed and crankshaft position are provided through the CKP (Crankshaft Position) sensor.
The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The
PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this
position, along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
A tonewheel is bolted to the engine crankshaft. This tonewheel has sets of notches (3) at its outer
edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM.

Fuel Level Sensor: Description and Operation
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant current source is supplied to the resistor track on the fuel
gauge sending unit. This is fed directly from the Powertrain Control Module (PCM).
NOTE: For diagnostic purposes, this 12V power source can only be verified with the circuit opened
(fuel pump module electrical connector unplugged). With the connectors plugged, output voltages
will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about 8.6 volts at EMPTY for
Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The resistor track is used to
vary the voltage (resistance) depending on fuel tank float level. As fuel level increases, the float
and arm move up, which decreases voltage. As fuel level decreases, the float and arm move down,
which increases voltage. The varied voltage signal is returned back to the PCM through the sensor
return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/ setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Intake Air Temperature Sensor: Description and Operation
The 2-wire Intake Manifold Air Temperature (IAT) sensor is installed in the intake manifold (2) with
the sensor element extending into the air stream.
The IAT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as intake
manifold temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
The IAT sensor provides an input voltage to the Powertrain Control Module (PCM) indicating the
density of the air entering the intake manifold based upon intake manifold temperature. At key-on,
a 5-volt power circuit is supplied to the sensor from the PCM. The sensor is grounded at the PCM
through a low-noise, sensor-return circuit.
The PCM uses this input to calculate the following:
- Injector pulse-width
- Adjustment of spark timing (to help prevent spark knock with high intake manifold air-charge
temperatures)
The resistance values of the IAT sensor is the same as for the Engine Coolant Temperature (ECT)
sensor.

Knock Sensor: Description and Operation
The sensors are used only with 3.7L V-6, 4.7L V-8 and 5.7L V-8 engines. On 3.7L V-6 and 4.7L
V-8 engines, the 2 knock sensors are bolted into the cylinder block under the intake manifold.
On 5.7L V-8 engines, 2 knock sensors are also used. These are bolted into each side of the
cylinder block (outside) under the exhaust manifold.
3.7L V-6/4.7L V-8/5.7L V-8 Engines Only
Two knock sensors are used; one for each cylinder bank. When the knock sensor detects a knock
in one of the cylinders on the corresponding bank, it sends an input signal to the Powertrain Control
Module (PCM). In response, the PCM retards ignition timing for all cylinders by a scheduled
amount.
Knock sensors contain a piezoelectric material which constantly vibrates and sends an input
voltage (signal) to the PCM while the engine operates. As the intensity of the crystal's vibration
increases, the knock sensor output voltage also increases.
The voltage signal produced by the knock sensor increases with the amplitude of vibration. The
PCM receives the knock sensor voltage signal as an input. If the signal rises above a
predetermined level, the PCM will store that value in memory and retard ignition timing to reduce
engine knock. If the knock sensor voltage exceeds a preset value, the PCM retards ignition timing
for all cylinders. It is not a selective cylinder retard.
The PCM ignores knock sensor input during engine idle conditions. Once the engine speed
exceeds a specified value, knock retard is allowed.
Knock retard uses its own short term and long term memory program.
Long term memory stores previous detonation information in its battery-backed RAM. The
maximum authority that long term memory has over timing retard can be calibrated.
NOTE: Over or under tightening the sensor mounting bolts will affect knock sensor performance,
possibly causing improper spark control. Always use the specified torque when installing the knock
sensors.
Short term memory is allowed to retard timing up to a preset amount under all operating conditions
(as long as rpm is above the minimum rpm) except at Wide Open Throttle (WOT). The PCM, using
short term memory, can respond quickly to retard timing when engine knock is detected. Short term
memory is lost any time the ignition key is turned off.

Manifold Pressure/Vacuum Sensor: Description and Operation
The Manifold Absolute Pressure (MAP) sensor is mounted to the front of the intake manifold air
plenum box.
The MAP sensor is used as an input to the Powertrain Control Module (PCM). It contains a silicon
based sensing unit to provide data on the manifold vacuum that draws the air/fuel mixture into the
combustion chamber. The PCM requires this information to determine injector pulse width and
spark advance. When manifold absolute pressure (MAP) equals Barometric pressure, the pulse
width will be at maximum.
A 5 volt reference is supplied from the PCM and returns a voltage signal to the PCM that reflects
manifold pressure. The zero pressure reading is 0.5V and full scale is 4.5V. For a pressure swing
of 0-15 psi, the voltage changes 4.0V. To operate the sensor, it is supplied a regulated 4.8 to 5.1
volts. Ground is provided through the low-noise, sensor return circuit at the PCM.
The MAP sensor input is the number one contributor to fuel injector pulse width. The most
important function of the MAP sensor is to determine barometric pressure. The PCM needs to
know if the vehicle is at sea level or at a higher altitude, because the air density changes with
altitude. It will also help to correct for varying barometric pressure. Barometric pressure and altitude
have a direct inverse correlation; as altitude goes up, barometric goes down. At key-on, the PCM
powers up and looks at MAP voltage, and based upon the voltage it sees, it knows the current
barometric pressure (relative to altitude). Once the engine starts, the PCM looks at the voltage
again, continuously every 12 milliseconds, and compares the current voltage to what it was at
key-on. The difference between current voltage and what it was at key-on, is manifold vacuum.
During key-on (engine not running) the sensor reads (updates) barometric pressure. A normal
range can be obtained by monitoring a known good sensor. As the altitude increases, the air
becomes thinner (less oxygen). If a vehicle is started and driven to a very different altitude than
where it was at key-on, the barometric pressure needs to be updated. Any time the PCM sees
Wide Open Throttle (WOT), based upon Throttle Position Sensor (TPS) angle and RPM, it will
update barometric pressure in the MAP memory cell. With periodic updates, the PCM can make its
calculations more effectively.
The PCM uses the MAP sensor input to aid in calculating the following:
- Manifold pressure
- Barometric pressure
- Engine load
- Injector pulse-width
- Spark-advance programs
- Shift-point strategies (certain automatic transmissions only)
- Idle speed
- Decel fuel shutoff
The MAP sensor signal is provided from a single piezoresistive element located in the center of a
diaphragm. The element and diaphragm are both made of silicone. As manifold pressure changes,
the diaphragm moves causing the element to deflect, which stresses the silicone. When silicone is
exposed to stress, its resistance changes. As manifold vacuum increases, the MAP sensor input
voltage decreases proportionally. The sensor also contains electronics that condition the signal and
provide temperature compensation.
The PCM recognizes a decrease in manifold pressure by monitoring a decrease in voltage from the
reading stored in the barometric pressure memory cell. The MAP sensor is a linear sensor;
meaning as pressure changes, voltage changes proportionately. The range of voltage output from
the sensor is usually between 4.6 volts at sea level to as low as 0.3 volts at 26 in. of Hg. Barometric
pressure is the pressure exerted by the atmosphere upon an

object. At sea level on a standard day, no storm, barometric pressure is approximately 29.92 in Hg.
For every 100 feet of altitude, barometric pressure drops 0.10 in. Hg. If a storm goes through, it can
change barometric pressure from what should be present for that altitude. You should know what
the average pressure and corresponding barometric pressure is for your area.

Power Steering Pressure Switch: Description and Operation
SWITCH-POWER STEERING PRESSURE
DESCRIPTION
A pressure sensing switch is used in the power steering system. It is mounted on the high-pressure
steering hose. This switch will only be used with on HD vehicles with the 5.7L engines. There is no
pressure switch used for the 3.7L, 4.7L, 5.9L engines or the 5.7L LD vehicle pump.
OPERATION
The switch is used on the 5.7L V-8 engines HD vehicles only.
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high steering pump load and low engine rpm; such as
during parking maneuvers. The PCM increases the idle speed through the Idle Air Control (IAC)
motor. This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the Normally
Closed (NC) switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

Transmission Position Switch/Sensor: Description and Operation
SENSOR-TRANSMISSION RANGE
DESCRIPTION
The Transmission Range Sensor (TRS) is part of the solenoid module, which is mounted to the top
of the valve body inside the transmission. The Transmission Range Sensor (TRS) has five switch
contact pins that: ^
Determine shift lever position
^ Supply ground to the Starter Relay in Park and Neutral only.
^ Supply +12 V to the backup lamps in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

Camshaft Position Sensor: Description and Operation
The Camshaft Position Sensor (CMP) on the 5.7L V-8 engine is located below the generator on the
timing chain/case cover on the right/front side of engine.
The CMP sensor is used in conjunction with the crankshaft position sensor to differentiate between
fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective
cylinders. The sensor generates electrical pulses. These pulses (signals) are sent to the Powertrain
Control Module (PCM). The PCM will then determine crankshaft position from both the camshaft
position sensor and crankshaft position sensor.
The tonewheel (2) is located at the front of the camshaft. As the tonewheel rotates, notches (3)
pass through the sync signal generator.
When the cam gear is rotating, the sensor will detect the notches. Input voltage from the sensor to
the PCM will then switch from a low (approximately 0.3 volts) to a high (approximately 5 volts).
When the sensor detects a notch has passed, the input voltage switches back low to approximately
0.3 volts.

Crankshaft Position Sensor: Description and Operation
The Crankshaft Position (CKP) (4) sensor is mounted into the right rear side of the cylinder block. It
is positioned and bolted into a machined hole.
Engine speed and crankshaft position are provided through the CKP (Crankshaft Position) sensor.
The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The
PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this
position, along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
A tonewheel is bolted to the engine crankshaft. This tonewheel has sets of notches (3) at its outer
edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM.

Knock Sensor: Description and Operation
The sensors are used only with 3.7L V-6, 4.7L V-8 and 5.7L V-8 engines. On 3.7L V-6 and 4.7L
V-8 engines, the 2 knock sensors are bolted into the cylinder block under the intake manifold.
On 5.7L V-8 engines, 2 knock sensors are also used. These are bolted into each side of the
cylinder block (outside) under the exhaust manifold.
3.7L V-6/4.7L V-8/5.7L V-8 Engines Only
Two knock sensors are used; one for each cylinder bank. When the knock sensor detects a knock
in one of the cylinders on the corresponding bank, it sends an input signal to the Powertrain Control
Module (PCM). In response, the PCM retards ignition timing for all cylinders by a scheduled
amount.
Knock sensors contain a piezoelectric material which constantly vibrates and sends an input
voltage (signal) to the PCM while the engine operates. As the intensity of the crystal's vibration
increases, the knock sensor output voltage also increases.
The voltage signal produced by the knock sensor increases with the amplitude of vibration. The
PCM receives the knock sensor voltage signal as an input. If the signal rises above a
predetermined level, the PCM will store that value in memory and retard ignition timing to reduce
engine knock. If the knock sensor voltage exceeds a preset value, the PCM retards ignition timing
for all cylinders. It is not a selective cylinder retard.
The PCM ignores knock sensor input during engine idle conditions. Once the engine speed
exceeds a specified value, knock retard is allowed.
Knock retard uses its own short term and long term memory program.
Long term memory stores previous detonation information in its battery-backed RAM. The
maximum authority that long term memory has over timing retard can be calibrated.
NOTE: Over or under tightening the sensor mounting bolts will affect knock sensor performance,
possibly causing improper spark control. Always use the specified torque when installing the knock
sensors.
Short term memory is allowed to retard timing up to a preset amount under all operating conditions
(as long as rpm is above the minimum rpm) except at Wide Open Throttle (WOT). The PCM, using
short term memory, can respond quickly to retard timing when engine knock is detected. Short term
memory is lost any time the ignition key is turned off.

Intake Air Temperature Sensor: Description and Operation
The 2-wire Intake Manifold Air Temperature (IAT) sensor is installed in the intake manifold (2) with
the sensor element extending into the air stream.
The IAT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as intake
manifold temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
The IAT sensor provides an input voltage to the Powertrain Control Module (PCM) indicating the
density of the air entering the intake manifold based upon intake manifold temperature. At key-on,
a 5-volt power circuit is supplied to the sensor from the PCM. The sensor is grounded at the PCM
through a low-noise, sensor-return circuit.
The PCM uses this input to calculate the following:
- Injector pulse-width
- Adjustment of spark timing (to help prevent spark knock with high intake manifold air-charge
temperatures)
The resistance values of the IAT sensor is the same as for the Engine Coolant Temperature (ECT)
sensor.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM (ECM Diesel) to
vary the battery charging rate. System voltage will be higher at colder temperatures and is
gradually reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20° F.

The Front Control Module (FCM) is a micro controller located in the left front corner of the engine
compartment. It is necessary to position the Integrated Power Module (IPM) aside in order to
access the front control module on this vehicle. The FCM mates to the Power Distribution Center
(PDC) to form the IPM. The IPM connects directly to the battery and provides the primary means of
circuit protection and power distribution for all vehicle electrical systems. The FCM controls power
to some of the vehicle systems electrical and electromechanical loads based on inputs received
from hard wired switch inputs and data received on the PCI bus circuit.
As messages are sent over the Programmable Communications Interface (PCI) data bus circuit,
the Front Control Module (FCM) reads these messages and controls power to some of the vehicles
electrical systems by completing the circuit to ground (low side driver) or completing the circuit to
12 volt power (high side driver). The following functions are Controlled by the FCM:
- Headlamp Power with Voltage Regulation
- Windshield Wiper "ON/OFF" Relay Actuation

A/C Status Indicator Flashing
A/C STATUS INDICATOR FLASHING
Theory of Operation
Running the AC Cooldown test will cause the A/C status indicator to flash. If the test fails, the
status indicator will continue to flash until either the test returns passed or the ignition key is cycled.
When the A/C status indicator is flashing, it will not indicate A/C operating status. However, the A/C
mode switch will continue to function normally. For vehicles equipped with EBL, when the A/C
status indicator is flashing, the EBL status indicator will not function. However, the EBL mode
switch will continue to function normally.
POSSIBLE CAUSES
- A/C Cooldown test failed
1. PERFORM THE A/C COOLDOWN TEST
NOTE: The following are prerequisites of the Cooldown Test. Verify each of the following before
running the test:
- Verify that no Evaporator Temperature Sensor related DTCs are not active. If active, diagnose
and repair the DTC before proceeding.
- Verify that the refrigerant system has an adequate charge. Check and repair as necessary before
proceeding.
- Verify that the blower motor operates correctly in all speeds. Diagnose and repair all blower
related faults before proceeding.
- Verify that the work area ambient temperature is above 21.1° C (70° F) before proceeding. Move

Actuator Circuit Test Diagnostics (Dual-Zone)
Theory of Operation
By running the Actuator Circuit Test, the A/C Heater Control can identify up to three door driver
circuits shorted simultaneously. A Short Too Complex fault will set if more than three door driver
circuits are shorted in the same direction (e.g. four door driver circuits all shorted to ground) or if
two or more door driver circuits are shorted with at least one door driver circuit shorted to ignition
and one door driver circuit shorted to ground. Fault messages displaying XXX Driver/Circuit
Shorted to Ignition/Battery and XXX Driver/Circuit Shorted to Ground will set on a per-driver basis.

Camshaft Position Sensor: Description and Operation
The Camshaft Position Sensor (CMP) on the 5.7L V-8 engine is located below the generator on the
timing chain/case cover on the right/front side of engine.
The CMP sensor is used in conjunction with the crankshaft position sensor to differentiate between
fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective
cylinders. The sensor generates electrical pulses. These pulses (signals) are sent to the Powertrain
Control Module (PCM). The PCM will then determine crankshaft position from both the camshaft
position sensor and crankshaft position sensor.
The tonewheel (2) is located at the front of the camshaft. As the tonewheel rotates, notches (3)
pass through the sync signal generator.
When the cam gear is rotating, the sensor will detect the notches. Input voltage from the sensor to
the PCM will then switch from a low (approximately 0.3 volts) to a high (approximately 5 volts).
When the sensor detects a notch has passed, the input voltage switches back low to approximately
0.3 volts.

Crankshaft Position Sensor: Description and Operation
The Crankshaft Position (CKP) (4) sensor is mounted into the right rear side of the cylinder block. It
is positioned and bolted into a machined hole.
Engine speed and crankshaft position are provided through the CKP (Crankshaft Position) sensor.
The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The
PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this
position, along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
A tonewheel is bolted to the engine crankshaft. This tonewheel has sets of notches (3) at its outer
edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM.

Electronic Throttle Control Indicator: Description and Operation
An Electronic Throttle Control (ETC) indicator is standard equipment on all gasoline engine
instrument clusters. However, on vehicles not equipped with the I/I optional 5.7 liter gasoline
engine, this indicator is electronically disabled. The ETC indicator is located on the right side of the
instrument cluster, to the right of the engine temperature gauge.
The ETC indicator consists of a stencil-like cutout of the International Control and Display Symbol
icon for "Electronic Throttle Control" in the opaque layer of the instrument cluster overlay. The dark
outer layer of the overlay prevents the indicator from being clearly visible when it is not illuminated.
A red Light Emitting Diode (LED) behind the cutout in the opaque layer of the overlay causes the
icon to appear in red through the translucent outer layer of the overlay when the indicator is
illuminated from behind by the LED, which is soldered onto the instrument cluster electronic circuit
board. The ETC indicator is serviced as a unit with the instrument cluster.
The Electronic Throttle Control (ETC) indicator gives an indication to the vehicle operator when the
ETC system is faulty or inoperative. The ETC indicator is controlled by a transistor on the
instrument cluster circuit board based upon cluster programming and electronic messages received
by the cluster from the Powertrain Control Module (PCM) over the Programmable Communications
Interface (PCI) data bus.
The ETC indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster
logic circuit, and that logic will only allow this indicator to operate when the instrument cluster
receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the
LED will always be off when the ignition switch is in any position except On or Start. The LED only
illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument
cluster will turn on the ETC indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the ETC indicator is
illuminated for about six seconds. The entire six second bulb test is a function of the PCM.
- ETC Lamp-On Message - Each time the cluster receives a lamp-on message from the PCM, the
ETC indicator will be illuminated. The indicator can be flashed on and off, or illuminated solid, as
dictated by the PCM message. The indicator remains illuminated solid or continues to flash for
about twelve seconds or until the cluster receives a lamp-off message from the PCM, whichever is
longer. If the indicator is illuminated solid with the engine running the vehicle will usually remain
drivable. If the indicator is flashing with the engine running the vehicle may require towing. A
flashing indicator means the ETC system requires immediate service.
- Communication Error - If the cluster receives no ETC lamp messages for three consecutive
seconds, the ETC indicator is illuminated. The indicator remains illuminated until the cluster
receives a single lamp-off message from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the ETC indicator will be
turned on, then off again during the bulb check portion of the test to confirm the functionality of the
LED and the cluster control circuitry. The actuator test illumination of the ETC indicator is a function
of the PCM.
The PCM continually monitors the ETC system circuits and sensors to decide whether the system
is in good operating condition. The PCM then sends the proper lamp-on or lamp-off messages to
the instrument cluster. If the PCM sends a lamp-on message after the bulb test, it indicates that the
PCM has detected a system malfunction and/or that the ETC system is inoperative. The PCM will
store a Diagnostic Trouble Code (DTC) for any malfunction it detects. Each time the ETC indicator
fails to illuminate due to an open or short in the cluster ETC indicator circuit, the cluster sends a
message notifying the PCM of the condition, the instrument cluster and the PCM will each store a
DTC.
For proper diagnosis of the ETC system, the PCM, the PCI data bus, or the electronic message
inputs to the instrument cluster that control the ETC indicator, a diagnostic scan tool is required.

NOTE:
Refer to the table for specific applications.
DISCUSSION:
Mopar(R) is currently phasing out pre-programmed PCMs for the vehicles listed. New modules will
no longer be pre-programmed when received from Mopar(R). Replacement of future PCMs will
require programming utilizing the DRBIII(R) and TechCONNECT. The PCM will not operate the
engine until it is programmed. A Diagnostic Trouble Code (DTC) will be set - "not programmed".
CAUTION:
Extreme care must be taken when programming a calibration into a generic PCM. Do not randomly
select a calibration. Once a calibration is selected and programmed, the controller cannot be
reprogrammed to a different calibration. The module can only be reprogrammed to a more recent
version of that calibration.

PARTS REQUIRED:
SPECIAL TOOLS/EQUIPMENT REQUIRED:
NOTE:
An updated J1962 cable has been released. This cable has a red colored connector at the
DRBIII(R) connection. Use this cable whenever a flash is being performed.
REPAIR PROCEDURE:
NOTE:
When flashing a 2002 - 2004 LH vehicle the BCM may need to be disconnected if experiencing
failures during the flash of the transmission portion of the PCM. The BCM will need to be
disconnected after the module ID portion of the flash is complete. Before pressing Page Forward to
begin the flash of the PCM Turn the Key to the OFF position and disconnect the BCM. Then turn
the KEY to the RUN position and Press Page Forward to begin the PCM flash session.
NOTE:
If vehicle is a DAKOTA, then the ABS CAB module connector MUST be disconnected prior to
performing this Repair Procedure. The CAB module and the PCM are connected at the same
diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB
module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is
complete turn the ignition switch to the OFF position, connect the CAB module connector, and then
check for any erroneous DTC's. If the PCM becomes "locked" during reprogramming because the
ABS CAB module connector was not disconnected, then the PCM may be recovered by following
the procedure in this NOTE.
NOTE:
Whenever a controller is programmed, the software in the DRBIII(R); must be programmed with the
latest revision level available.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted and then follow the
directions on the DRBIII(R).
1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from
the DRBIII(R) memory. To clear the memory from the MAIN MENU power up the DRBIII(R) and
then:
a. Simultaneously press the "MORE" and "YES" keys.
b. A screen will appear requesting a "COLD BOOT".
c. Follow the on screen instructions by selecting the "F4" key.
d. When the DRB III(R) reboots to the MAIN MENU, proceed to Step 2.

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.

NUMBER: 23-014-06
GROUP: Body
DATE: March 8, 2006
SUBJECT: Windshield Wiper Blade/Element Maintenance
MODELS: All
All All Chrysler Group Vehicles
DISCUSSION:
Windshield wiper blades/elements are frequently replaced unnecessarily. Because of the
environmental conditions vehicles can be operated in, a film can build up on both the windshield
and the windshield wiper elements that will cause poor cleaning/streaking of the windshield, and in
some instances, a chattering condition as the wipers blades travel across the windshield.
Replacement of the wiper blades/elements is normally NOT required to correct streaking issues. A
simple NORMAL MAINTENANCE cleaning of the wiper blades/elements and windshield is all that
is required.
If the wipe pattern appears to be streaky or if there is chatter and no damage to the wiper
blades/elements is obvious, the following steps should be performed:
1. Use a soft cloth or sponge & squeegee and MOPAR Windshield Washer Solvent (p/n
04318067AB, 16 Oz. bottle or p/n 04318068AB, 32 Oz. bottle), MOPAR Glass Cleaner (p/n
04897623AB, 16 Oz. bottle) or a solution of 50/50 alcohol and water, to wash the windshield.
2. Raise the wiper blades off the glass and clean the wiper blade elements (rubber insert) with
MOPAR Windshield Washer Solvent or a solution of 50/50 alcohol and water and a soft cloth,
paper towel or sponge.
3. Return the wiper blades to their normal operating position and function the washer system. If the
wiper blades/elements are not streaking the windshield or chattering, replacing the blade
assembly(ies) is not necessary. If the wipe pattern is still objectionable, repeat step 2 several times.
If the wipe pattern is still objectionable, replace the wiper blades/elements.

Engine Control Module: Description and Operation PCM
The Powertrain Control Module (PCM) is located in the right-rear section of the engine
compartment under the cowl.
Two different PCM's are used (JTEC and NGC). These can be easily identified. JTEC's use three
32-way connectors, NGC's use four 38-way connectors.
The PCM operates the fuel system. The PCM is a pre-programmed, triple microprocessor digital
computer. It regulates ignition timing, air-fuel ratio, emission control devices, charging system,
certain transmission features, speed control, air conditioning compressor clutch engagement and
idle speed. The PCM can adapt its programming to meet changing operating conditions.
The PCM receives input signals from various switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operations through different system components. These
components are referred to as Powertrain Control Module (PCM) Outputs. The sensors and
switches that provide inputs to the PCM are considered Powertrain Control Module (PCM) Inputs.
The PCM adjusts ignition timing based upon inputs it receives from sensors that react to: engine
rpm, manifold absolute pressure, engine coolant temperature, throttle position, transmission gear
selection (automatic transmission), vehicle speed, power steering pump pressure, and the brake
switch.
The PCM adjusts idle speed based on inputs it receives from sensors that react to: throttle position,
vehicle speed, transmission gear selection, engine coolant temperature and from inputs it receives
from the air conditioning clutch switch and brake switch.
Based on inputs that it receives, the PCM adjusts ignition coil dwell. The PCM also adjusts the
generator charge rate through control of the generator field and provides speed control operation.

Engine Control Module: Description and Operation Modes of Operation
As input signals to the Powertrain Control Module (PCM) change, the PCM adjusts its response to
the output devices. For example, the PCM must calculate different injector pulse width and ignition
timing for idle than it does for wide open throttle (WOT).
The PCM will operate in two different modes: Open Loop and Closed Loop.
During Open Loop modes, the PCM receives input signals and responds only according to preset
PCM programming. Input from the oxygen (02S) sensors is not monitored during Open Loop
modes.
During Closed Loop modes, the PCM will monitor the oxygen (02S) sensors input. This input
indicates to the PCM whether or not the calculated injector pulse width results in the ideal air-fuel
ratio. This ratio is 14.7 parts air-to-1 part fuel. By monitoring the exhaust oxygen content through
the 02S sensor, the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance.
The fuel injection system has the following modes of operation:
- Ignition switch ON
- Engine start-up (crank)
- Engine warm-up
- Idle
- Cruise
- Acceleration
- Deceleration
- Wide open throttle (WOT)
- Ignition switch OFF
The ignition switch On, engine start-up (crank), engine warm-up, acceleration, deceleration and
wide open throttle modes are Open Loop modes. The idle and cruise modes, (with the engine at
operating temperature) are Closed Loop modes.
IGNITION SWITCH (KEY-ON) MODE
This is an Open Loop mode. When the fuel system is activated by the ignition switch, the following
actions occur:
- The PCM pre-positions the idle air control (IAC) motor.
- The PCM determines atmospheric air pressure from the MAP sensor input to determine basic fuel
strategy.
- The PCM monitors the engine coolant temperature sensor input. The PCM modifies fuel strategy
based on this input.
- Intake manifold air temperature sensor input is monitored.
- Throttle position sensor (TPS) is monitored.
- The auto shutdown (ASD) relay is energized by the PCM for approximately three seconds.
- The fuel pump is energized through the fuel pump relay by the PCM. The fuel pump will operate
for approximately three seconds unless the engine is operating or the starter motor is engaged.
- The 02S sensor heater element is energized via the ASD or 02S heater relay. The 02S sensor
input is not used by the PCM to calibrate air-fuel ratio during this mode of operation.
ENGINE START-UP MODE
This is an Open Loop mode. The following actions occur when the starter motor is engaged. The
PCM receives inputs from:
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
The PCM monitors the crankshaft position sensor. If the PCM does not receive a crankshaft
position sensor signal within 3 seconds of cranking the engine, it will shut down the fuel injection
system.
The fuel pump is activated by the PCM through the fuel pump relay.
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
The PCM determines the proper ignition timing according to input received from the crankshaft
position sensor.
ENGINE WARM-UP MODE
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module >
Component Information > Description and Operation > PCM > Page 2713
This is an Open Loop mode. During engine warm-up, the PCM receives inputs from:
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
Based on these inputs the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
- The PCM adjusts engine idle speed through the idle air control (IAC) motor and adjusts ignition
timing.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
- When engine has reached operating temperature, the PCM will begin monitoring 02S sensor
input. The system will then leave the warm-up mode and go into closed loop operation.
IDLE MODE
When the engine is at operating temperature, this is a Closed Loop mode. At idle speed, the PCM
receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Battery voltage
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen sensors Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
injection sequence and injector pulse width by turning the ground circuit to each individual injector
on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio by varying injector pulse width.
It also adjusts engine idle speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by increasing and decreasing spark advance.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
CRUISE MODE
When the engine is at operating temperature, this is a Closed Loop mode. At cruising speed, the
PCM receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen (02S) sensors Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then adjust
the injector pulse width by turning the ground circuit to each individual injector on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio. It also adjusts engine idle
speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module >
Component Information > Description and Operation > PCM > Page 2714
ACCELERATION MODE
This is an Open Loop mode. The PCM recognizes an abrupt increase in throttle position or MAP
pressure as a demand for increased engine output and vehicle acceleration. The PCM increases
injector pulse width in response to increased throttle opening.
DECELERATION MODE
When the engine is at operating temperature, this is an Open Loop mode. During hard
deceleration, the PCM receives the following inputs.
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Vehicle speed
If the vehicle is under hard deceleration with the proper rpm and closed throttle conditions, the
PCM will ignore the oxygen sensor input signal. The PCM will enter a fuel cut-off strategy in which
it will not supply a ground to the injectors. If a hard deceleration does not exist, the PCM will
determine the proper injector pulse width and continue injection.
Based on the above inputs, the PCM will adjust engine idle speed through the idle air control (IAC)
motor. The PCM adjusts ignition timing by turning the ground path to the coil on and off.
WIDE OPEN THROTTLE MODE
This is an Open Loop mode. During wide open throttle operation, the PCM receives the following
inputs.
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal During wide open throttle conditions, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off. The PCM ignores the oxygen sensor input signal and provides a predetermined
amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
IGNITION SWITCH OFF MODE
When ignition switch is turned to OFF position, the PCM stops operating the injectors, ignition coil,
ASD relay and fuel pump relay.

Engine Control Module: Description and Operation Ignition Circuit Sense
This circuit ties the ignition switch to the Powertrain Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage on the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.

Engine Control Module: Description and Operation
PCM
The Powertrain Control Module (PCM) is located in the right-rear section of the engine
compartment under the cowl.
Two different PCM's are used (JTEC and NGC). These can be easily identified. JTEC's use three
32-way connectors, NGC's use four 38-way connectors.
The PCM operates the fuel system. The PCM is a pre-programmed, triple microprocessor digital
computer. It regulates ignition timing, air-fuel ratio, emission control devices, charging system,
certain transmission features, speed control, air conditioning compressor clutch engagement and
idle speed. The PCM can adapt its programming to meet changing operating conditions.
The PCM receives input signals from various switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operations through different system components. These
components are referred to as Powertrain Control Module (PCM) Outputs. The sensors and
switches that provide inputs to the PCM are considered Powertrain Control Module (PCM) Inputs.
The PCM adjusts ignition timing based upon inputs it receives from sensors that react to: engine
rpm, manifold absolute pressure, engine coolant temperature, throttle position, transmission gear
selection (automatic transmission), vehicle speed, power steering pump pressure, and the brake
switch.
The PCM adjusts idle speed based on inputs it receives from sensors that react to: throttle position,
vehicle speed, transmission gear selection, engine coolant temperature and from inputs it receives
from the air conditioning clutch switch and brake switch.
Based on inputs that it receives, the PCM adjusts ignition coil dwell. The PCM also adjusts the
generator charge rate through control of the generator field and provides speed control operation.

Modes of Operation
As input signals to the Powertrain Control Module (PCM) change, the PCM adjusts its response to
the output devices. For example, the PCM must calculate different injector pulse width and ignition
timing for idle than it does for wide open throttle (WOT).
The PCM will operate in two different modes: Open Loop and Closed Loop.
During Open Loop modes, the PCM receives input signals and responds only according to preset
PCM programming. Input from the oxygen (02S) sensors is not monitored during Open Loop
modes.
During Closed Loop modes, the PCM will monitor the oxygen (02S) sensors input. This input
indicates to the PCM whether or not the calculated injector pulse width results in the ideal air-fuel
ratio. This ratio is 14.7 parts air-to-1 part fuel. By monitoring the exhaust oxygen content through
the 02S sensor, the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance.
The fuel injection system has the following modes of operation:
- Ignition switch ON
- Engine start-up (crank)
- Engine warm-up
- Idle
- Cruise
- Acceleration
- Deceleration
- Wide open throttle (WOT)
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module >
Component Information > Description and Operation > PCM > Page 2719
- Ignition switch OFF
The ignition switch On, engine start-up (crank), engine warm-up, acceleration, deceleration and
wide open throttle modes are Open Loop modes. The idle and cruise modes, (with the engine at
operating temperature) are Closed Loop modes.
IGNITION SWITCH (KEY-ON) MODE
This is an Open Loop mode. When the fuel system is activated by the ignition switch, the following
actions occur:
- The PCM pre-positions the idle air control (IAC) motor.
- The PCM determines atmospheric air pressure from the MAP sensor input to determine basic fuel
strategy.
- The PCM monitors the engine coolant temperature sensor input. The PCM modifies fuel strategy
based on this input.
- Intake manifold air temperature sensor input is monitored.
- Throttle position sensor (TPS) is monitored.
- The auto shutdown (ASD) relay is energized by the PCM for approximately three seconds.
- The fuel pump is energized through the fuel pump relay by the PCM. The fuel pump will operate
for approximately three seconds unless the engine is operating or the starter motor is engaged.
- The 02S sensor heater element is energized via the ASD or 02S heater relay. The 02S sensor
input is not used by the PCM to calibrate air-fuel ratio during this mode of operation.
ENGINE START-UP MODE
This is an Open Loop mode. The following actions occur when the starter motor is engaged. The
PCM receives inputs from:
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
The PCM monitors the crankshaft position sensor. If the PCM does not receive a crankshaft
position sensor signal within 3 seconds of cranking the engine, it will shut down the fuel injection
system.
The fuel pump is activated by the PCM through the fuel pump relay.
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
The PCM determines the proper ignition timing according to input received from the crankshaft
position sensor.
ENGINE WARM-UP MODE
This is an Open Loop mode. During engine warm-up, the PCM receives inputs from:
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
Based on these inputs the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
- The PCM adjusts engine idle speed through the idle air control (IAC) motor and adjusts ignition
timing.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
- When engine has reached operating temperature, the PCM will begin monitoring 02S sensor
input. The system will then leave the warm-up mode and go into closed loop operation.
IDLE MODE
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module >
Component Information > Description and Operation > PCM > Page 2720
When the engine is at operating temperature, this is a Closed Loop mode. At idle speed, the PCM
receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Battery voltage
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen sensors Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
injection sequence and injector pulse width by turning the ground circuit to each individual injector
on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio by varying injector pulse width.
It also adjusts engine idle speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by increasing and decreasing spark advance.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
CRUISE MODE
When the engine is at operating temperature, this is a Closed Loop mode. At cruising speed, the
PCM receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen (02S) sensors Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then adjust
the injector pulse width by turning the ground circuit to each individual injector on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio. It also adjusts engine idle
speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
ACCELERATION MODE
This is an Open Loop mode. The PCM recognizes an abrupt increase in throttle position or MAP
pressure as a demand for increased engine output and vehicle acceleration. The PCM increases
injector pulse width in response to increased throttle opening.
DECELERATION MODE
When the engine is at operating temperature, this is an Open Loop mode. During hard
deceleration, the PCM receives the following inputs.
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Vehicle speed
If the vehicle is under hard deceleration with the proper rpm and closed throttle conditions, the
PCM will ignore the oxygen sensor input signal. The PCM will enter a fuel cut-off strategy in which
it will not supply a ground to the injectors. If a hard deceleration does not exist, the PCM will
determine the proper injector pulse width and continue injection.

Component Information > Description and Operation > PCM > Page 2721
Based on the above inputs, the PCM will adjust engine idle speed through the idle air control (IAC)
motor. The PCM adjusts ignition timing by turning the ground path to the coil on and off.
WIDE OPEN THROTTLE MODE
This is an Open Loop mode. During wide open throttle operation, the PCM receives the following
inputs.
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal During wide open throttle conditions, the following occurs:

the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off. The PCM ignores the oxygen sensor input signal and provides a predetermined
amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
IGNITION SWITCH OFF MODE
When ignition switch is turned to OFF position, the PCM stops operating the injectors, ignition coil,
ASD relay and fuel pump relay.
5 Volt Supplies
Two different Powertrain Control Module (PCM) five volt supply circuits are used; primary and
secondary.
Primary 5-volt supply:

Secondary 5-volt supply:
- supplies the required 5 volt power source to the oil pressure sensor.
- supplies the required 5 volt power source for the Vehicle Speed Sensor (VSS) (if equipped).
- supplies the 5 volt power source to the transmission pressure sensor (certain automatic
transmissions).
Ignition Circuit Sense
This circuit ties the ignition switch to the Powertrain Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage on the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.
Power Grounds
The Powertrain Control Module (PCM) has 2 main grounds. Both of these grounds are referred to
as power grounds. All of the high-current, noisy, electrical devices are connected to these grounds
as well as all of the sensor returns. The sensor return comes into the sensor return circuit, passes
through noise suppression, and is then connected to the power ground.
The power ground is used to control ground circuits for the following PCM loads:
- Generator field winding
- Fuel injectors
- Ignition coil(s)
- Certain relays/solenoids
- Certain sensors
Sensor Return
The Sensor Return circuits are internal to the Powertrain Control Module (PCM).

Engine Control Module: Service and Repair PCM/ECM/SKIM Programming
NOTE: Before replacing the Powertrain Control Module (PCM) or Engine Control Module (ECM),
be certain to check the related component/circuit integrity for failures not detected due to a double
fault in the circuit. Most PCM/ECM driver/control circuit failures are caused by internal component
failures (i.e. relays and solenoids) and shorted circuits (i.e. pull-ups, drivers, and switched circuits).
These failures are difficult to detect when a double fault has occurred and only one DTC has been
set.
When a Powertrain Control Module (PCM) for a gasoline engine, or a Engine Control Module for a
diesel engine and the Sentry Key Immobilizer Module (SKIM) on vehicles equipped with the Sentry
Key Immobilizer System (SKIS) are replaced at the same time, perform the following steps in order:
1. Program the new PCM/ECM. 2. Program the new SKIM. 3. Replace all ignition keys and
program them into the new SKIM.

Engine Control Module: Service and Repair Programming the PCM/ECM/SKIM
The SKIS Secret Key is an ID code that is unique to each SKIM. This code is programmed and
stored in the SKIM, the PCM/ECM, and each ignition key transponder chip. When the PCM/ECM or
SKIM is replaced, it is necessary to program the Secret Key into the new modules using a
diagnostic scan tool. Follow the programming steps outlined in the diagnostic scan tool menu for
the module being replaced as appropriate.
NOTE:
- Be certain to enter the correct country code for the SKIM. If the incorrect country code is
programmed into the SKIM, it cannot be changed and the SKIM must be replaced.
- If the PCM/ECM and the SKIM are replaced at the same time, all vehicle ignition keys will need to
be replaced and the new keys programmed into the new SKIM.
- Programming the PCM/ECM or SKIM is done using a diagnostic scan tool and a PIN to enter
secure access mode. If three attempts are made to enter secure access mode using an incorrect
PIN, secure access mode will be locked out for one hour. To exit this lockout mode, turn the
ignition to the RUN position for one hour then enter the correct PIN. (Ensure all accessories are
turned OFF. Also monitor the battery state and connect a battery charger if necessary).

Engine Control Module: Service and Repair Programming Ignition Keys to the SKIM
Each ignition key transponder also has a unique ID code that is assigned at the time the key is
manufactured. When a key is programmed into the SKIM, the transponder ID code is learned by
the module and the transponder acquires the unique Secret Key ID code from the SKIM. To
program ignition keys into the SKIM, follow the programming steps outlined in the diagnostic scan
tool for "Program Ignition Keys or Key FOBs" under the "SKIM" menu item.
NOTE: A maximum of eight keys can be learned to each SKIM. Once a key is learned to a SKIM,
that key has acquired the Secret Key for that SKIM and cannot be transferred to any other SKIM or
vehicle.
If ignition key programming is unsuccessful, the scan tool will display one of the following error
messages:
- Programming Not Attempted - The scan tool attempts to read the programmed key status and
there are no keys programmed into SKIM memory.
- Programming Key Failed (Possible Used Key From Wrong Vehicle) - SKIM is unable to program
an ignition key transponder due to one of the following: The ignition key transponder is faulty.
- The ignition key transponder is or has been already programmed to another vehicle.
- 8 Keys Already Learned, Programming Not Done - The SKIM transponder ID memory is full.
- Learned Key In Ignition - The ID for the ignition key transponder currently in the ignition lock
cylinder is already programmed into SKIM memory.

Engine Control Module: Service and Repair Module - Powertrain Control
CAUTION:
- Certain ABS systems rely on having the Powertrain Control Module (PCM) broadcast the Vehicle
Identification Number (VIN) over the bus network. To prevent problems of DTCs and other items
related to the VIN broadcast, it is recommend that you disconnect the ABS CAB (controller)
temporarily when replacing the PCM. Once the PCM is replaced, write the VIN to the PCM using
the DRB scan tool. This is done from the engine main menu. Arrow over to the second page to "1.
Miscellaneous". Select "Check VIN" from the choices. Make sure it has the correct VIN entered
before continuing. When the VIN is complete, turn off the ignition key and reconnect the ABS
module connector. This will prevent the setting of DTCs and other items associated with the lack of
a VIN detected when you turn the key ON after replacing the PCM.
- Use the DRB scan tool to reprogram the new PCM with the vehicles original identification number
(VIN) and the vehicles original mileage. If this step is not done, a Diagnostic Trouble Code (DTC)
may be set.
REMOVAL
The PCM (1) is located in the engine compartment attached to the dash panel (3).
To avoid possible voltage spike damage to the PCM, ignition key must be off, and negative battery
cable must be disconnected before unplugging PCM connectors.

Component Information > Locations > Page 2733
Fuel Level Sensor: Description and Operation
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant current source is supplied to the resistor track on the fuel
gauge sending unit. This is fed directly from the Powertrain Control Module (PCM).
NOTE: For diagnostic purposes, this 12V power source can only be verified with the circuit opened
(fuel pump module electrical connector unplugged). With the connectors plugged, output voltages
will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about 8.6 volts at EMPTY for
Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The resistor track is used to
vary the voltage (resistance) depending on fuel tank float level. As fuel level increases, the float
and arm move up, which decreases voltage. As fuel level decreases, the float and arm move down,
which increases voltage. The varied voltage signal is returned back to the PCM through the sensor
return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/ setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Information Bus: Description and Operation
The DaimlerChrysler Programmable Communication Interface (PCI) data bus system is a single
wire multiplex system used for vehicle communications on many DaimlerChrysler Corporation
vehicles. Multiplexing is a system that enables the transmission of several messages over a single
channel or circuit. All DaimlerChrysler vehicles use this principle for communication between
various microprocessor-based electronic control modules. The PCI data bus exceeds the Society
of Automotive Engineers (SAE) J1850 Standard for Class B Multiplexing.
Many of the electronic control modules in a vehicle require information from the same sensing
device. In the past, if information from one sensing device was required by several controllers, a
wire from each controller needed to be connected in parallel to that sensor. In addition, each
controller utilizing analog sensors required an Analog/Digital (A/D) converter in order to "read"
these sensor inputs. Multiplexing reduces wire harness complexity, sensor current loads and
controller hardware because each sensing device is connected to only one controller, which reads
and distributes the sensor information to the other controllers over the data bus. Also, because
each controller on the data bus can access the controller sensor inputs to every other controller on
the data bus, more function and feature capabilities are possible.
In addition to reducing wire harness complexity, component sensor current loads and controller
hardware, multiplexing offers a diagnostic advantage. A multiplex system allows the information
flowing between controllers to be monitored using a diagnostic scan tool. The DaimlerChrysler
system allows an electronic control module to broadcast message data out onto the bus where all
other electronic control modules can "hear" the messages that are being sent. When a module
hears a message on the data bus that it requires, it relays that message to its microprocessor.
Each module ignores the messages on the data bus that are being sent to other electronic control
modules.
Data exchange between modules is achieved by serial transmission of encoded data over a single
wire broadcast network. The wire colors used for the PCI data bus circuits are yellow with a violet
tracer, or violet with a yellow tracer, depending upon the application. The PCI data bus messages
are carried over the bus in the form of Variable Pulse Width Modulated (VPWM) signals. The PCI
data bus speed is an average 10.4 Kilo-bits per second (Kbps). By comparison, the prior two-wire
Chrysler Collision Detection (CCD) data bus system is designed to run at 7.8125 Kbps.
The voltage network used to transmit messages requires biasing and termination. Each module on
the PCI data bus system provides its own biasing and termination. Each module (also referred to
as a node) terminates the bus through a terminating resistor and a terminating capacitor. There are
two types of nodes on the bus. The dominant node terminates the bus through a 1 KW resistor and
a 3300 pF capacitor. The Powertrain Control Module (PCM) is the only dominant node for the PCI
data bus system. A standard node terminates the bus through an 11 KW resistor and a 330 pF
capacitor.
The modules bias the bus when transmitting a message. The PCI bus uses low and high voltage
levels to generate signals. Low voltage is around zero volts and the high voltage is about seven
and one-half volts. The low and high voltage levels are generated by means of variable-pulse width
modulation to form signals of varying length. The Variable Pulse Width Modulation (VPWM) used in
PCI bus messaging is a method in which both the state of the bus and the width of the pulse are
used to encode bit information. A "zero" bit is defined as a short low pulse or a long high pulse. A
"one" bit is defined as a long low pulse or a short high pulse. A low (passive) state on the bus does
not necessarily mean a zero bit. It also depends upon pulse width. If the width is short, it stands for
a zero bit. If the width is long, it stands for a one bit. Similarly, a high (active) state does not
necessarily mean a one bit. This too depends upon pulse width. If the width is short, it stands for a
one bit. If the width is long, it stands for a zero bit.
In the case where there are successive zero or one data bits, both the state of the bus and the
width of the pulse are changed alternately. This encoding scheme is used for two reasons. First,
this ensures that only one symbol per transition and one transition per symbol exists. On each
transition, every transmitting module must decode the symbol on the bus and begin timing of the
next symbol. Since timing of the next symbol begins with the last transition detected on the bus, all
of the modules are re-synchronized with each symbol. This ensures that there are no accumulated
timing errors during PCI data bus communication.
The second reason for this encoding scheme is to guarantee that the zero bit is the dominant bit on
the bus. When two modules are transmitting simultaneously on the bus, there must be some form
of arbitration to determine which module will gain control. A data collision occurs when two
modules are transmitting different messages at the same time. When a module is transmitting on
the bus, it is reading the bus at the same time to ensure message integrity. When a collision is
detected, the module that transmitted the one bit stops sending messages over the bus until the
bus becomes idle.
Each module is capable of transmitting and receiving data simultaneously. The typical PCI bus
message has the following four components:
- Message Header - One to three bytes in length. The header contains information identifying the
message type and length, message priority, target module(s) and sending module.
- Data Byte(s) - This is the actual message that is being sent.
- Cyclic Redundancy Check (CRC) Byte - This byte is used to detect errors during a message
transmission.
- In-Frame Response (IFR) byte(s) - If a response is required from the target module(s), it can be
sent during this frame. This function is described in greater detail in the following paragraph.
The IFR consists of one or more bytes, which are transmitted during a message. If the sending
module requires information to be received immediately, the target module(s) can send data over
the bus during the original message. This allows the sending module to receive time-critical
information without having to wait for the target module to access the bus. After the IFR is received,
the sending module broadcasts an End of Frame (EOF) message and releases control of the bus.
The PCI data bus can be monitored using a diagnostic scan tool. It is possible, however, for the
bus to pass all diagnostic scan tool tests and still be faulty if the voltage parameters are all within
the specified range and false messages are being sent.

Knock Sensor: Description and Operation
The sensors are used only with 3.7L V-6, 4.7L V-8 and 5.7L V-8 engines. On 3.7L V-6 and 4.7L
V-8 engines, the 2 knock sensors are bolted into the cylinder block under the intake manifold.
On 5.7L V-8 engines, 2 knock sensors are also used. These are bolted into each side of the
cylinder block (outside) under the exhaust manifold.
3.7L V-6/4.7L V-8/5.7L V-8 Engines Only
Two knock sensors are used; one for each cylinder bank. When the knock sensor detects a knock
in one of the cylinders on the corresponding bank, it sends an input signal to the Powertrain Control
Module (PCM). In response, the PCM retards ignition timing for all cylinders by a scheduled
amount.
Knock sensors contain a piezoelectric material which constantly vibrates and sends an input
voltage (signal) to the PCM while the engine operates. As the intensity of the crystal's vibration
increases, the knock sensor output voltage also increases.
The voltage signal produced by the knock sensor increases with the amplitude of vibration. The
PCM receives the knock sensor voltage signal as an input. If the signal rises above a
predetermined level, the PCM will store that value in memory and retard ignition timing to reduce
engine knock. If the knock sensor voltage exceeds a preset value, the PCM retards ignition timing
for all cylinders. It is not a selective cylinder retard.
The PCM ignores knock sensor input during engine idle conditions. Once the engine speed
exceeds a specified value, knock retard is allowed.
Knock retard uses its own short term and long term memory program.
Long term memory stores previous detonation information in its battery-backed RAM. The
maximum authority that long term memory has over timing retard can be calibrated.
NOTE: Over or under tightening the sensor mounting bolts will affect knock sensor performance,
possibly causing improper spark control. Always use the specified torque when installing the knock
sensors.
Short term memory is allowed to retard timing up to a preset amount under all operating conditions
(as long as rpm is above the minimum rpm) except at Wide Open Throttle (WOT). The PCM, using
short term memory, can respond quickly to retard timing when engine knock is detected. Short term
memory is lost any time the ignition key is turned off.

Main Relay (Computer/Fuel System): Description and Operation PCM Output
The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power Distribution Center
(PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit on and off.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if:
- the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.

Main Relay (Computer/Fuel System): Description and Operation ASD Sense - PCM Input
A 12 volt signal at this input indicates to the PCM that the ASD has been activated. The relay is
used to connect the oxygen sensor heater element, ignition coil and fuel injectors to 12 volt +
power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Main Relay (Computer/Fuel System): Testing and Inspection
ASD AND FUEL PUMP RELAYS
The following description of operation and tests apply only to the Automatic Shutdown (ASD) and
fuel pump relays. The terminals on the bottom of each relay are numbered. Two different types of
relays may be used, or.
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays,
terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to
terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the
circuit. Terminal 87A is the center terminal on the relay.
- When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30.
This is the On position. Terminal 87 supplies voltage to the rest of the circuit.
The following procedure applies to the ASD and fuel pump relays.
1. Remove relay from connector before testing. 2. With the relay removed from the vehicle, use an
ohmmeter to check the resistance between terminals 85 and 86. The resistance should be 75
ohms
+/- 5 ohms.
3. Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity
between terminals 30 and 87A. 4. Connect the ohmmeter between terminals 87 and 30. The
ohmmeter should not show continuity at this time. 5. Connect one end of a jumper wire (16 gauge
or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12
volt power source.
6. Connect one end of another jumper wire (16 gauge or smaller) to the power side of the 12 volt
power source. Do not attach the other end of the
jumper wire to the relay at this time.
WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS
TEST. DAMAGE TO OHMMETER MAY RESULT.
7. Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The
ohmmeter should now show continuity between relay
terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and
30.

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Malfunction Indicator Lamp >
Component Information > Description and Operation
Malfunction Indicator Lamp: Description and Operation
A Malfunction Indicator Lamp (MIL) is standard equipment on all instrument clusters. This indicator
is located on the left side of the instrument cluster, to the left of the voltage gauge.
The MIL consists of a stencil-like cutout of the International Control and Display Symbol icon for
"Engine" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. An amber Light Emitting
Diode (LED) behind the cutout in the opaque layer of the overlay causes the icon to appear in
amber through the translucent outer layer of the overlay when the indicator is illuminated from
behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The MIL
is serviced as a unit with the instrument cluster.
The Malfunction Indicator Lamp (MIL) gives an indication to the vehicle operator when the
Powertrain Control Module (PCM) on vehicles with a gasoline engine, or the Engine Control
Module (ECM) on vehicles with a diesel engine has recorded a Diagnostic Trouble Code (DTC) for
an On-Board Diagnostics II (OBDII) emissions-related circuit or component malfunction. The MIL is
controlled by a transistor on the instrument cluster circuit board based upon cluster programming
and electronic messages received by the cluster from the PCM or ECM over the Programmable
Communications Interface (PCI) data bus.
The MIL Light Emitting Diode (LED) is completely controlled by the instrument cluster logic circuit,
and that logic will only allow this indicator to operate when the instrument cluster receives a battery
current input on the fused ignition switch output (run-start) circuit. Therefore, the LED will always be
off when the ignition switch is in any position except On or Start. The LED only illuminates when it
is provided a path to ground by the instrument cluster transistor. The instrument cluster will turn on
the MIL for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the indicator is illuminated for
about two seconds as a bulb test. The entire bulb test is a function of the PCM or ECM.
- MIL Lamp-On Message - Each time the cluster receives a MIL lamp-on message from the PCM or
ECM, the indicator will be illuminated. The indicator can be flashed on and off, or illuminated solid,
as dictated by the PCM or ECM message. For some DTC's, if a problem does not recur, the PCM
or ECM will send a lamp-off message automatically. Other DTC's may require that a fault be
repaired and the PCM or ECM be reset before a lamp-off message will be sent.
- Communication Error - If the cluster receives no messages from the PCM or ECM for about ten
seconds, the MIL is illuminated by the instrument cluster to indicate a loss of bus communication.
The indicator remains controlled and illuminated by the cluster until a valid message is received
from the PCM or ECM.
- Actuator Test - Each time the cluster is put through the actuator test, the MIL indicator will be
turned on during the bulb check portion of the test to confirm the functionality of the LED and the
cluster control circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the fuel and emissions system
circuits and sensors to decide whether the system is in good operating condition. On vehicles with
a diesel engine, the ECM continually monitors the fuel and emissions system circuits and sensors
to decide whether the system is in good operating condition. The PCM or ECM then sends the
proper lamp-on or lamp-off messages to the instrument cluster. For further diagnosis of the MIL or
the instrument cluster circuitry that controls the LED, refer to testing. If the instrument cluster turns
on the MIL after the bulb test, it may indicate that a malfunction has occurred and that the fuel and
emissions systems may require service.
For proper diagnosis of the fuel and emissions systems, the PCM, the ECM, the PCI data bus, or
the electronic message inputs to the instrument cluster that control the MIL, a diagnostic scan tool
is required.

Manifold Pressure/Vacuum Sensor: Description and Operation
The Manifold Absolute Pressure (MAP) sensor is mounted to the front of the intake manifold air
plenum box.
The MAP sensor is used as an input to the Powertrain Control Module (PCM). It contains a silicon
based sensing unit to provide data on the manifold vacuum that draws the air/fuel mixture into the
combustion chamber. The PCM requires this information to determine injector pulse width and
spark advance. When manifold absolute pressure (MAP) equals Barometric pressure, the pulse
width will be at maximum.
A 5 volt reference is supplied from the PCM and returns a voltage signal to the PCM that reflects
manifold pressure. The zero pressure reading is 0.5V and full scale is 4.5V. For a pressure swing
of 0-15 psi, the voltage changes 4.0V. To operate the sensor, it is supplied a regulated 4.8 to 5.1
volts. Ground is provided through the low-noise, sensor return circuit at the PCM.
The MAP sensor input is the number one contributor to fuel injector pulse width. The most
important function of the MAP sensor is to determine barometric pressure. The PCM needs to
know if the vehicle is at sea level or at a higher altitude, because the air density changes with
altitude. It will also help to correct for varying barometric pressure. Barometric pressure and altitude
have a direct inverse correlation; as altitude goes up, barometric goes down. At key-on, the PCM
powers up and looks at MAP voltage, and based upon the voltage it sees, it knows the current
barometric pressure (relative to altitude). Once the engine starts, the PCM looks at the voltage
again, continuously every 12 milliseconds, and compares the current voltage to what it was at
key-on. The difference between current voltage and what it was at key-on, is manifold vacuum.
During key-on (engine not running) the sensor reads (updates) barometric pressure. A normal
range can be obtained by monitoring a known good sensor. As the altitude increases, the air
becomes thinner (less oxygen). If a vehicle is started and driven to a very different altitude than
where it was at key-on, the barometric pressure needs to be updated. Any time the PCM sees
Wide Open Throttle (WOT), based upon Throttle Position Sensor (TPS) angle and RPM, it will
update barometric pressure in the MAP memory cell. With periodic updates, the PCM can make its
calculations more effectively.
The PCM uses the MAP sensor input to aid in calculating the following:
- Manifold pressure
- Barometric pressure
- Engine load
- Injector pulse-width
- Spark-advance programs
- Shift-point strategies (certain automatic transmissions only)
- Idle speed
- Decel fuel shutoff
The MAP sensor signal is provided from a single piezoresistive element located in the center of a
diaphragm. The element and diaphragm are both made of silicone. As manifold pressure changes,
the diaphragm moves causing the element to deflect, which stresses the silicone. When silicone is
exposed to stress, its resistance changes. As manifold vacuum increases, the MAP sensor input
voltage decreases proportionally. The sensor also contains electronics that condition the signal and
provide temperature compensation.
The PCM recognizes a decrease in manifold pressure by monitoring a decrease in voltage from the
reading stored in the barometric pressure memory cell. The MAP sensor is a linear sensor;
meaning as pressure changes, voltage changes proportionately. The range of voltage output from
the sensor is usually between 4.6 volts at sea level to as low as 0.3 volts at 26 in. of Hg. Barometric
pressure is the pressure exerted by the atmosphere upon an

object. At sea level on a standard day, no storm, barometric pressure is approximately 29.92 in Hg.
For every 100 feet of altitude, barometric pressure drops 0.10 in. Hg. If a storm goes through, it can
change barometric pressure from what should be present for that altitude. You should know what
the average pressure and corresponding barometric pressure is for your area.

Power Steering Pressure Switch: Description and Operation
SWITCH-POWER STEERING PRESSURE
DESCRIPTION
A pressure sensing switch is used in the power steering system. It is mounted on the high-pressure
steering hose. This switch will only be used with on HD vehicles with the 5.7L engines. There is no
pressure switch used for the 3.7L, 4.7L, 5.9L engines or the 5.7L LD vehicle pump.
OPERATION
The switch is used on the 5.7L V-8 engines HD vehicles only.
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high steering pump load and low engine rpm; such as
during parking maneuvers. The PCM increases the idle speed through the Idle Air Control (IAC)
motor. This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the Normally
Closed (NC) switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

Body Control Module: Description and Operation
The Front Control Module (FCM) is a micro controller located in the left front corner of the engine
compartment. It is necessary to position the Integrated Power Module (IPM) aside in order to
access the front control module on this vehicle. The FCM mates to the Power Distribution Center
(PDC) to form the IPM. The IPM connects directly to the battery and provides the primary means of
circuit protection and power distribution for all vehicle electrical systems. The FCM controls power
to some of the vehicle systems electrical and electromechanical loads based on inputs received
from hard wired switch inputs and data received on the PCI bus circuit.
As messages are sent over the Programmable Communications Interface (PCI) data bus circuit,
the Front Control Module (FCM) reads these messages and controls power to some of the vehicles
electrical systems by completing the circuit to ground (low side driver) or completing the circuit to
12 volt power (high side driver). The following functions are Controlled by the FCM:
- Headlamp Power with Voltage Regulation
- Windshield Wiper "ON/OFF" Relay Actuation
- Windshield Wiper "HI/LO" Relay Actuation
- Windshield Washer Pump Motor
- Fog Lamp Relay Actuation
- Park Lamp Relay Actuation
- Horn Relay Actuation
The following inputs are Received/Monitored by the FCM:
- B+ Connection Detection
- Power Ground
- Ambient Temperature Sensing
- Ignition Switch Run
- Washer Fluid Level Switch
- Windshield Wiper Park Switch
- PCI Data Bus Circuit

OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE SUPPLEMENTAL RESTRAINT
SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT.
The hard wired chime warning system inputs to the ElectroMechanical Instrument Cluster (EMIC),
as well as other hard wired circuits for this system may be diagnosed and tested using
conventional diagnostic tools and methods. The wiring information includes wiring diagrams, proper
wire and connector repair procedures, details of wire harness routing and retention, connector
pin-out information and location views for the various wire harness connectors, splices and
grounds.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the EMIC,
the Programmable Communications Interface (PCI) data bus, or the electronic message inputs
used by the EMIC to provide chime warning system service. The most reliable, efficient, and
accurate means to diagnose the EMIC, the PCI data bus, and the electronic message inputs for the
chime warning system requires the use of a diagnostic scan tool.

A/C Status Indicator Flashing
A/C STATUS INDICATOR FLASHING
Theory of Operation
Running the AC Cooldown test will cause the A/C status indicator to flash. If the test fails, the
status indicator will continue to flash until either the test returns passed or the ignition key is cycled.
When the A/C status indicator is flashing, it will not indicate A/C operating status. However, the A/C
mode switch will continue to function normally. For vehicles equipped with EBL, when the A/C
status indicator is flashing, the EBL status indicator will not function. However, the EBL mode
switch will continue to function normally.
POSSIBLE CAUSES
- A/C Cooldown test failed
1. PERFORM THE A/C COOLDOWN TEST
NOTE: The following are prerequisites of the Cooldown Test. Verify each of the following before
running the test:
- Verify that no Evaporator Temperature Sensor related DTCs are not active. If active, diagnose
and repair the DTC before proceeding.
- Verify that the refrigerant system has an adequate charge. Check and repair as necessary before
proceeding.
- Verify that the blower motor operates correctly in all speeds. Diagnose and repair all blower
related faults before proceeding.
- Verify that the work area ambient temperature is above 21.1° C (70° F) before proceeding. Move
the vehicle to a warmer work area if necessary.
- Verify that the evaporator temperature is above 12.7° C (55° F) before proceeding.
- Verify that the Mode Select control is set to the panel position.

NOTE:
Refer to the table for specific applications.
DISCUSSION:
Mopar(R) is currently phasing out pre-programmed PCMs for the vehicles listed. New modules will
no longer be pre-programmed when received from Mopar(R). Replacement of future PCMs will
require programming utilizing the DRBIII(R) and TechCONNECT. The PCM will not operate the
engine until it is programmed. A Diagnostic Trouble Code (DTC) will be set - "not programmed".
CAUTION:
Extreme care must be taken when programming a calibration into a generic PCM. Do not randomly
select a calibration. Once a calibration is selected and programmed, the controller cannot be
reprogrammed to a different calibration. The module can only be reprogrammed to a more recent
version of that calibration.

PARTS REQUIRED:
SPECIAL TOOLS/EQUIPMENT REQUIRED:
NOTE:
An updated J1962 cable has been released. This cable has a red colored connector at the
DRBIII(R) connection. Use this cable whenever a flash is being performed.
REPAIR PROCEDURE:
NOTE:
When flashing a 2002 - 2004 LH vehicle the BCM may need to be disconnected if experiencing
failures during the flash of the transmission portion of the PCM. The BCM will need to be
disconnected after the module ID portion of the flash is complete. Before pressing Page Forward to
begin the flash of the PCM Turn the Key to the OFF position and disconnect the BCM. Then turn
the KEY to the RUN position and Press Page Forward to begin the PCM flash session.
NOTE:
If vehicle is a DAKOTA, then the ABS CAB module connector MUST be disconnected prior to
performing this Repair Procedure. The CAB module and the PCM are connected at the same
diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB
module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is
complete turn the ignition switch to the OFF position, connect the CAB module connector, and then
check for any erroneous DTC's. If the PCM becomes "locked" during reprogramming because the
ABS CAB module connector was not disconnected, then the PCM may be recovered by following
the procedure in this NOTE.
NOTE:
Whenever a controller is programmed, the software in the DRBIII(R); must be programmed with the
latest revision level available.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted and then follow the
directions on the DRBIII(R).
1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from
the DRBIII(R) memory. To clear the memory from the MAIN MENU power up the DRBIII(R) and
then:

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.
2007 GRAND CHEROKEE W/ 3.0L TD/2005 - 2007 LIBERTY w/2.8L TD/2007 RAM TRUCK/RAM
CAB CHASSIS w 6.7L TD AND 2004-2006 SPRINTER w 2.7L TD ENGINES.
For the above models equipped with Turbo Diesel Engines, the fuel injector "Quantity Values" must
be physically read from each injector and the values written to the ECU with an appropriate scan
tool.

NOTE:
Refer to the table for specific applications.
DISCUSSION:
Mopar(R) is currently phasing out pre-programmed PCMs for the vehicles listed. New modules will
no longer be pre-programmed when received from Mopar(R). Replacement of future PCMs will
require programming utilizing the DRBIII(R) and TechCONNECT. The PCM will not operate the
engine until it is programmed. A Diagnostic Trouble Code (DTC) will be set - "not programmed".
CAUTION:
Extreme care must be taken when programming a calibration into a generic PCM. Do not randomly
select a calibration. Once a calibration is selected and programmed, the controller cannot be
reprogrammed to a different calibration. The module can only be reprogrammed to a more recent
version of that calibration.

PARTS REQUIRED:
SPECIAL TOOLS/EQUIPMENT REQUIRED:
NOTE:
An updated J1962 cable has been released. This cable has a red colored connector at the
DRBIII(R) connection. Use this cable whenever a flash is being performed.
REPAIR PROCEDURE:
NOTE:
When flashing a 2002 - 2004 LH vehicle the BCM may need to be disconnected if experiencing
failures during the flash of the transmission portion of the PCM. The BCM will need to be
disconnected after the module ID portion of the flash is complete. Before pressing Page Forward to
begin the flash of the PCM Turn the Key to the OFF position and disconnect the BCM. Then turn
the KEY to the RUN position and Press Page Forward to begin the PCM flash session.
NOTE:
If vehicle is a DAKOTA, then the ABS CAB module connector MUST be disconnected prior to
performing this Repair Procedure. The CAB module and the PCM are connected at the same
diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB
module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is
complete turn the ignition switch to the OFF position, connect the CAB module connector, and then
check for any erroneous DTC's. If the PCM becomes "locked" during reprogramming because the
ABS CAB module connector was not disconnected, then the PCM may be recovered by following
the procedure in this NOTE.
NOTE:
Whenever a controller is programmed, the software in the DRBIII(R); must be programmed with the
latest revision level available.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted and then follow the
directions on the DRBIII(R).
1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from
the DRBIII(R) memory. To clear the memory from the MAIN MENU power up the DRBIII(R) and
then:
a. Simultaneously press the "MORE" and "YES" keys.
b. A screen will appear requesting a "COLD BOOT".
c. Follow the on screen instructions by selecting the "F4" key.
d. When the DRB III(R) reboots to the MAIN MENU, proceed to Step 2.

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.

Engine Control Module: Description and Operation PCM
The Powertrain Control Module (PCM) is located in the right-rear section of the engine
compartment under the cowl.
Two different PCM's are used (JTEC and NGC). These can be easily identified. JTEC's use three
32-way connectors, NGC's use four 38-way connectors.
The PCM operates the fuel system. The PCM is a pre-programmed, triple microprocessor digital
computer. It regulates ignition timing, air-fuel ratio, emission control devices, charging system,
certain transmission features, speed control, air conditioning compressor clutch engagement and
idle speed. The PCM can adapt its programming to meet changing operating conditions.
The PCM receives input signals from various switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operations through different system components. These
components are referred to as Powertrain Control Module (PCM) Outputs. The sensors and
switches that provide inputs to the PCM are considered Powertrain Control Module (PCM) Inputs.
The PCM adjusts ignition timing based upon inputs it receives from sensors that react to: engine
rpm, manifold absolute pressure, engine coolant temperature, throttle position, transmission gear
selection (automatic transmission), vehicle speed, power steering pump pressure, and the brake
switch.
The PCM adjusts idle speed based on inputs it receives from sensors that react to: throttle position,
vehicle speed, transmission gear selection, engine coolant temperature and from inputs it receives
from the air conditioning clutch switch and brake switch.
Based on inputs that it receives, the PCM adjusts ignition coil dwell. The PCM also adjusts the
generator charge rate through control of the generator field and provides speed control operation.

Engine Control Module: Description and Operation Modes of Operation
As input signals to the Powertrain Control Module (PCM) change, the PCM adjusts its response to
the output devices. For example, the PCM must calculate different injector pulse width and ignition
timing for idle than it does for wide open throttle (WOT).
The PCM will operate in two different modes: Open Loop and Closed Loop.
During Open Loop modes, the PCM receives input signals and responds only according to preset
PCM programming. Input from the oxygen (02S) sensors is not monitored during Open Loop
modes.
During Closed Loop modes, the PCM will monitor the oxygen (02S) sensors input. This input
indicates to the PCM whether or not the calculated injector pulse width results in the ideal air-fuel
ratio. This ratio is 14.7 parts air-to-1 part fuel. By monitoring the exhaust oxygen content through
the 02S sensor, the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance.
The fuel injection system has the following modes of operation:
- Ignition switch ON
- Engine start-up (crank)
- Engine warm-up
- Idle
- Cruise
- Acceleration
- Deceleration
- Wide open throttle (WOT)
- Ignition switch OFF
The ignition switch On, engine start-up (crank), engine warm-up, acceleration, deceleration and
wide open throttle modes are Open Loop modes. The idle and cruise modes, (with the engine at
operating temperature) are Closed Loop modes.
IGNITION SWITCH (KEY-ON) MODE
This is an Open Loop mode. When the fuel system is activated by the ignition switch, the following
actions occur:
- The PCM pre-positions the idle air control (IAC) motor.
- The PCM determines atmospheric air pressure from the MAP sensor input to determine basic fuel
strategy.
- The PCM monitors the engine coolant temperature sensor input. The PCM modifies fuel strategy
based on this input.
- Intake manifold air temperature sensor input is monitored.
- Throttle position sensor (TPS) is monitored.
- The auto shutdown (ASD) relay is energized by the PCM for approximately three seconds.
- The fuel pump is energized through the fuel pump relay by the PCM. The fuel pump will operate
for approximately three seconds unless the engine is operating or the starter motor is engaged.
- The 02S sensor heater element is energized via the ASD or 02S heater relay. The 02S sensor
input is not used by the PCM to calibrate air-fuel ratio during this mode of operation.
ENGINE START-UP MODE
This is an Open Loop mode. The following actions occur when the starter motor is engaged. The
PCM receives inputs from:
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
The PCM monitors the crankshaft position sensor. If the PCM does not receive a crankshaft
position sensor signal within 3 seconds of cranking the engine, it will shut down the fuel injection
system.
The fuel pump is activated by the PCM through the fuel pump relay.
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
The PCM determines the proper ignition timing according to input received from the crankshaft
position sensor.
ENGINE WARM-UP MODE
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Description and Operation > PCM >
Page 3060
This is an Open Loop mode. During engine warm-up, the PCM receives inputs from:
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
Based on these inputs the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
- The PCM adjusts engine idle speed through the idle air control (IAC) motor and adjusts ignition
timing.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
- When engine has reached operating temperature, the PCM will begin monitoring 02S sensor
input. The system will then leave the warm-up mode and go into closed loop operation.
IDLE MODE
When the engine is at operating temperature, this is a Closed Loop mode. At idle speed, the PCM
receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Battery voltage
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen sensors Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
injection sequence and injector pulse width by turning the ground circuit to each individual injector
on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio by varying injector pulse width.
It also adjusts engine idle speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by increasing and decreasing spark advance.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
CRUISE MODE
When the engine is at operating temperature, this is a Closed Loop mode. At cruising speed, the
PCM receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen (02S) sensors Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then adjust
the injector pulse width by turning the ground circuit to each individual injector on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio. It also adjusts engine idle
speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.

Page 3061
ACCELERATION MODE
This is an Open Loop mode. The PCM recognizes an abrupt increase in throttle position or MAP
pressure as a demand for increased engine output and vehicle acceleration. The PCM increases
injector pulse width in response to increased throttle opening.
DECELERATION MODE
When the engine is at operating temperature, this is an Open Loop mode. During hard
deceleration, the PCM receives the following inputs.
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Vehicle speed
If the vehicle is under hard deceleration with the proper rpm and closed throttle conditions, the
PCM will ignore the oxygen sensor input signal. The PCM will enter a fuel cut-off strategy in which
it will not supply a ground to the injectors. If a hard deceleration does not exist, the PCM will
determine the proper injector pulse width and continue injection.
Based on the above inputs, the PCM will adjust engine idle speed through the idle air control (IAC)
motor. The PCM adjusts ignition timing by turning the ground path to the coil on and off.
WIDE OPEN THROTTLE MODE
This is an Open Loop mode. During wide open throttle operation, the PCM receives the following
inputs.
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal During wide open throttle conditions, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off. The PCM ignores the oxygen sensor input signal and provides a predetermined
amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
IGNITION SWITCH OFF MODE
When ignition switch is turned to OFF position, the PCM stops operating the injectors, ignition coil,
ASD relay and fuel pump relay.

Engine Control Module: Description and Operation Ignition Circuit Sense
This circuit ties the ignition switch to the Powertrain Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage on the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.

computer. It regulates ignition timing, air-fuel ratio, emission control devices, charging system,
certain transmission features, speed control, air conditioning compressor clutch engagement and
idle speed. The PCM can adapt its programming to meet changing operating conditions.
The PCM receives input signals from various switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operations through different system components. These
components are referred to as Powertrain Control Module (PCM) Outputs. The sensors and
switches that provide inputs to the PCM are considered Powertrain Control Module (PCM) Inputs.
The PCM adjusts ignition timing based upon inputs it receives from sensors that react to: engine
rpm, manifold absolute pressure, engine coolant temperature, throttle position, transmission gear
selection (automatic transmission), vehicle speed, power steering pump pressure, and the brake
switch.
The PCM adjusts idle speed based on inputs it receives from sensors that react to: throttle position,
vehicle speed, transmission gear selection, engine coolant temperature and from inputs it receives
from the air conditioning clutch switch and brake switch.
Based on inputs that it receives, the PCM adjusts ignition coil dwell. The PCM also adjusts the
generator charge rate through control of the generator field and provides speed control operation.

Modes of Operation
As input signals to the Powertrain Control Module (PCM) change, the PCM adjusts its response to
the output devices. For example, the PCM must calculate different injector pulse width and ignition
timing for idle than it does for wide open throttle (WOT).
The PCM will operate in two different modes: Open Loop and Closed Loop.
During Open Loop modes, the PCM receives input signals and responds only according to preset
PCM programming. Input from the oxygen (02S) sensors is not monitored during Open Loop
modes.
During Closed Loop modes, the PCM will monitor the oxygen (02S) sensors input. This input
indicates to the PCM whether or not the calculated injector pulse width results in the ideal air-fuel
ratio. This ratio is 14.7 parts air-to-1 part fuel. By monitoring the exhaust oxygen content through
the 02S sensor, the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance.
The fuel injection system has the following modes of operation:
- Ignition switch ON
- Engine start-up (crank)
- Engine warm-up
- Idle
- Cruise
- Acceleration
- Deceleration
- Wide open throttle (WOT)

Page 3066
- Ignition switch OFF
The ignition switch On, engine start-up (crank), engine warm-up, acceleration, deceleration and
wide open throttle modes are Open Loop modes. The idle and cruise modes, (with the engine at
operating temperature) are Closed Loop modes.
IGNITION SWITCH (KEY-ON) MODE
This is an Open Loop mode. When the fuel system is activated by the ignition switch, the following
actions occur:
- The PCM pre-positions the idle air control (IAC) motor.
- The PCM determines atmospheric air pressure from the MAP sensor input to determine basic fuel
strategy.
- The PCM monitors the engine coolant temperature sensor input. The PCM modifies fuel strategy
based on this input.
- Intake manifold air temperature sensor input is monitored.
- Throttle position sensor (TPS) is monitored.
- The auto shutdown (ASD) relay is energized by the PCM for approximately three seconds.
- The fuel pump is energized through the fuel pump relay by the PCM. The fuel pump will operate
for approximately three seconds unless the engine is operating or the starter motor is engaged.
- The 02S sensor heater element is energized via the ASD or 02S heater relay. The 02S sensor
input is not used by the PCM to calibrate air-fuel ratio during this mode of operation.
ENGINE START-UP MODE
This is an Open Loop mode. The following actions occur when the starter motor is engaged. The
PCM receives inputs from:
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
The PCM monitors the crankshaft position sensor. If the PCM does not receive a crankshaft
position sensor signal within 3 seconds of cranking the engine, it will shut down the fuel injection
system.
The fuel pump is activated by the PCM through the fuel pump relay.
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
The PCM determines the proper ignition timing according to input received from the crankshaft
position sensor.
ENGINE WARM-UP MODE
This is an Open Loop mode. During engine warm-up, the PCM receives inputs from:
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
Based on these inputs the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off.
- The PCM adjusts engine idle speed through the idle air control (IAC) motor and adjusts ignition
timing.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
- When engine has reached operating temperature, the PCM will begin monitoring 02S sensor
input. The system will then leave the warm-up mode and go into closed loop operation.
IDLE MODE
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Description and Operation > PCM >
Page 3067
When the engine is at operating temperature, this is a Closed Loop mode. At idle speed, the PCM
receives inputs from:
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor

injection sequence and injector pulse width by turning the ground circuit to each individual injector
on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio by varying injector pulse width.
It also adjusts engine idle speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by increasing and decreasing spark advance.
- The PCM operates the A/C compressor clutch through the A/C compressor clutch relay. This is
done if A/C has been selected by the vehicle operator and specified pressures are met at the high
and low-pressure A/C switches.
CRUISE MODE
When the engine is at operating temperature, this is a Closed Loop mode. At cruising speed, the
PCM receives inputs from:

- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen (02S) sensors Based on these inputs, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then adjust
the injector pulse width by turning the ground circuit to each individual injector on and off.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio. It also adjusts engine idle
speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
ACCELERATION MODE
This is an Open Loop mode. The PCM recognizes an abrupt increase in throttle position or MAP
pressure as a demand for increased engine output and vehicle acceleration. The PCM increases
injector pulse width in response to increased throttle opening.
DECELERATION MODE
When the engine is at operating temperature, this is an Open Loop mode. During hard
deceleration, the PCM receives the following inputs.
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Vehicle speed
If the vehicle is under hard deceleration with the proper rpm and closed throttle conditions, the
PCM will ignore the oxygen sensor input signal. The PCM will enter a fuel cut-off strategy in which
it will not supply a ground to the injectors. If a hard deceleration does not exist, the PCM will
determine the proper injector pulse width and continue injection.

Page 3068
Based on the above inputs, the PCM will adjust engine idle speed through the idle air control (IAC)
motor. The PCM adjusts ignition timing by turning the ground path to the coil on and off.
WIDE OPEN THROTTLE MODE

- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal During wide open throttle conditions, the following occurs:

the injection sequence and injector pulse width by turning the ground circuit to each individual
injector on and off. The PCM ignores the oxygen sensor input signal and provides a predetermined
amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.
IGNITION SWITCH OFF MODE
When ignition switch is turned to OFF position, the PCM stops operating the injectors, ignition coil,
ASD relay and fuel pump relay.
5 Volt Supplies
Two different Powertrain Control Module (PCM) five volt supply circuits are used; primary and
secondary.
Primary 5-volt supply:
- supplies the required 5 volt power source to the Crankshaft Position (CKP) sensor.
- supplies the required 5 volt power source to the Camshaft Position (CMP) sensor.
- supplies a reference voltage for the Manifold Absolute Pressure (MAP) sensor.
- supplies a reference voltage for the Throttle Position Sensor (TPS) sensor.
Secondary 5-volt supply:
- supplies the required 5 volt power source to the oil pressure sensor.
- supplies the required 5 volt power source for the Vehicle Speed Sensor (VSS) (if equipped).
- supplies the 5 volt power source to the transmission pressure sensor (certain automatic
transmissions).
Ignition Circuit Sense
This circuit ties the ignition switch to the Powertrain Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage on the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.
Power Grounds
The Powertrain Control Module (PCM) has 2 main grounds. Both of these grounds are referred to
as power grounds. All of the high-current, noisy, electrical devices are connected to these grounds
as well as all of the sensor returns. The sensor return comes into the sensor return circuit, passes
through noise suppression, and is then connected to the power ground.
The power ground is used to control ground circuits for the following PCM loads:
- Generator field winding
- Fuel injectors
- Ignition coil(s)
- Certain relays/solenoids
- Certain sensors
Sensor Return
The Sensor Return circuits are internal to the Powertrain Control Module (PCM).
Sensor Return provides a low-noise ground reference for all engine control system sensors.

PCM/ECM/SKIM Programming
Engine Control Module: Service and Repair PCM/ECM/SKIM Programming
NOTE: Before replacing the Powertrain Control Module (PCM) or Engine Control Module (ECM),
be certain to check the related component/circuit integrity for failures not detected due to a double
fault in the circuit. Most PCM/ECM driver/control circuit failures are caused by internal component
failures (i.e. relays and solenoids) and shorted circuits (i.e. pull-ups, drivers, and switched circuits).
These failures are difficult to detect when a double fault has occurred and only one DTC has been
set.
When a Powertrain Control Module (PCM) for a gasoline engine, or a Engine Control Module for a
diesel engine and the Sentry Key Immobilizer Module (SKIM) on vehicles equipped with the Sentry
Key Immobilizer System (SKIS) are replaced at the same time, perform the following steps in order:
1. Program the new PCM/ECM. 2. Program the new SKIM. 3. Replace all ignition keys and
program them into the new SKIM.

PCM/ECM/SKIM Programming > Page 3071
Engine Control Module: Service and Repair Programming the PCM/ECM/SKIM
The SKIS Secret Key is an ID code that is unique to each SKIM. This code is programmed and
stored in the SKIM, the PCM/ECM, and each ignition key transponder chip. When the PCM/ECM or
SKIM is replaced, it is necessary to program the Secret Key into the new modules using a
diagnostic scan tool. Follow the programming steps outlined in the diagnostic scan tool menu for
the module being replaced as appropriate.
NOTE:
- Be certain to enter the correct country code for the SKIM. If the incorrect country code is
programmed into the SKIM, it cannot be changed and the SKIM must be replaced.
- If the PCM/ECM and the SKIM are replaced at the same time, all vehicle ignition keys will need to
be replaced and the new keys programmed into the new SKIM.
- Programming the PCM/ECM or SKIM is done using a diagnostic scan tool and a PIN to enter
secure access mode. If three attempts are made to enter secure access mode using an incorrect
PIN, secure access mode will be locked out for one hour. To exit this lockout mode, turn the
ignition to the RUN position for one hour then enter the correct PIN. (Ensure all accessories are
turned OFF. Also monitor the battery state and connect a battery charger if necessary).

Engine Control Module: Service and Repair Programming Ignition Keys to the SKIM
Each ignition key transponder also has a unique ID code that is assigned at the time the key is
manufactured. When a key is programmed into the SKIM, the transponder ID code is learned by
the module and the transponder acquires the unique Secret Key ID code from the SKIM. To
program ignition keys into the SKIM, follow the programming steps outlined in the diagnostic scan
tool for "Program Ignition Keys or Key FOBs" under the "SKIM" menu item.
NOTE: A maximum of eight keys can be learned to each SKIM. Once a key is learned to a SKIM,
that key has acquired the Secret Key for that SKIM and cannot be transferred to any other SKIM or
vehicle.
If ignition key programming is unsuccessful, the scan tool will display one of the following error
messages:
- Programming Not Attempted - The scan tool attempts to read the programmed key status and
there are no keys programmed into SKIM memory.
- Programming Key Failed (Possible Used Key From Wrong Vehicle) - SKIM is unable to program
an ignition key transponder due to one of the following: The ignition key transponder is faulty.
- The ignition key transponder is or has been already programmed to another vehicle.
- 8 Keys Already Learned, Programming Not Done - The SKIM transponder ID memory is full.
- Learned Key In Ignition - The ID for the ignition key transponder currently in the ignition lock
cylinder is already programmed into SKIM memory.

Engine Control Module: Service and Repair Module - Powertrain Control
CAUTION:
- Certain ABS systems rely on having the Powertrain Control Module (PCM) broadcast the Vehicle
Identification Number (VIN) over the bus network. To prevent problems of DTCs and other items
related to the VIN broadcast, it is recommend that you disconnect the ABS CAB (controller)
temporarily when replacing the PCM. Once the PCM is replaced, write the VIN to the PCM using
the DRB scan tool. This is done from the engine main menu. Arrow over to the second page to "1.
Miscellaneous". Select "Check VIN" from the choices. Make sure it has the correct VIN entered
before continuing. When the VIN is complete, turn off the ignition key and reconnect the ABS
module connector. This will prevent the setting of DTCs and other items associated with the lack of
a VIN detected when you turn the key ON after replacing the PCM.
- Use the DRB scan tool to reprogram the new PCM with the vehicles original identification number
(VIN) and the vehicles original mileage. If this step is not done, a Diagnostic Trouble Code (DTC)
may be set.
REMOVAL
The PCM (1) is located in the engine compartment attached to the dash panel (3).
To avoid possible voltage spike damage to the PCM, ignition key must be off, and negative battery
cable must be disconnected before unplugging PCM connectors.

Main Relay (Computer/Fuel System): Description and Operation PCM Output
The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power Distribution Center
(PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit on and off.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if:
- the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.

A 12 volt signal at this input indicates to the PCM that the ASD has been activated. The relay is
used to connect the oxygen sensor heater element, ignition coil and fuel injectors to 12 volt +
power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Main Relay (Computer/Fuel System): Testing and Inspection
ASD AND FUEL PUMP RELAYS
The following description of operation and tests apply only to the Automatic Shutdown (ASD) and
fuel pump relays. The terminals on the bottom of each relay are numbered. Two different types of
relays may be used, or.
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays,
terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to
terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the
circuit. Terminal 87A is the center terminal on the relay.
- When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30.
This is the On position. Terminal 87 supplies voltage to the rest of the circuit.
The following procedure applies to the ASD and fuel pump relays.
1. Remove relay from connector before testing. 2. With the relay removed from the vehicle, use an
ohmmeter to check the resistance between terminals 85 and 86. The resistance should be 75
ohms
+/- 5 ohms.
3. Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity
between terminals 30 and 87A. 4. Connect the ohmmeter between terminals 87 and 30. The
ohmmeter should not show continuity at this time. 5. Connect one end of a jumper wire (16 gauge
or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12
volt power source.
6. Connect one end of another jumper wire (16 gauge or smaller) to the power side of the 12 volt
power source. Do not attach the other end of the
jumper wire to the relay at this time.
WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS
TEST. DAMAGE TO OHMMETER MAY RESULT.
7. Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The
ohmmeter should now show continuity between relay
terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and
30.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM (ECM Diesel) to
vary the battery charging rate. System voltage will be higher at colder temperatures and is
gradually reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20° F.

Camshaft Position Sensor: Description and Operation
The Camshaft Position Sensor (CMP) on the 5.7L V-8 engine is located below the generator on the
timing chain/case cover on the right/front side of engine.
The CMP sensor is used in conjunction with the crankshaft position sensor to differentiate between
fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective
cylinders. The sensor generates electrical pulses. These pulses (signals) are sent to the Powertrain
Control Module (PCM). The PCM will then determine crankshaft position from both the camshaft
position sensor and crankshaft position sensor.
The tonewheel (2) is located at the front of the camshaft. As the tonewheel rotates, notches (3)
pass through the sync signal generator.
When the cam gear is rotating, the sensor will detect the notches. Input voltage from the sensor to
the PCM will then switch from a low (approximately 0.3 volts) to a high (approximately 5 volts).
When the sensor detects a notch has passed, the input voltage switches back low to approximately
0.3 volts.

Fuel Level Sensor: Description and Operation
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant current source is supplied to the resistor track on the fuel
gauge sending unit. This is fed directly from the Powertrain Control Module (PCM).
NOTE: For diagnostic purposes, this 12V power source can only be verified with the circuit opened
(fuel pump module electrical connector unplugged). With the connectors plugged, output voltages
will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about 8.6 volts at EMPTY for
Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The resistor track is used to
vary the voltage (resistance) depending on fuel tank float level. As fuel level increases, the float
and arm move up, which decreases voltage. As fuel level decreases, the float and arm move down,
which increases voltage. The varied voltage signal is returned back to the PCM through the sensor
return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/ setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Intake Air Temperature Sensor: Description and Operation
The 2-wire Intake Manifold Air Temperature (IAT) sensor is installed in the intake manifold (2) with
the sensor element extending into the air stream.
The IAT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as intake
manifold temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
The IAT sensor provides an input voltage to the Powertrain Control Module (PCM) indicating the
density of the air entering the intake manifold based upon intake manifold temperature. At key-on,
a 5-volt power circuit is supplied to the sensor from the PCM. The sensor is grounded at the PCM
through a low-noise, sensor-return circuit.
The PCM uses this input to calculate the following:
- Injector pulse-width
- Adjustment of spark timing (to help prevent spark knock with high intake manifold air-charge
temperatures)
The resistance values of the IAT sensor is the same as for the Engine Coolant Temperature (ECT)
sensor.

Knock Sensor: Description and Operation
The sensors are used only with 3.7L V-6, 4.7L V-8 and 5.7L V-8 engines. On 3.7L V-6 and 4.7L
V-8 engines, the 2 knock sensors are bolted into the cylinder block under the intake manifold.
On 5.7L V-8 engines, 2 knock sensors are also used. These are bolted into each side of the
cylinder block (outside) under the exhaust manifold.
3.7L V-6/4.7L V-8/5.7L V-8 Engines Only
Two knock sensors are used; one for each cylinder bank. When the knock sensor detects a knock
in one of the cylinders on the corresponding bank, it sends an input signal to the Powertrain Control
Module (PCM). In response, the PCM retards ignition timing for all cylinders by a scheduled
amount.
Knock sensors contain a piezoelectric material which constantly vibrates and sends an input
voltage (signal) to the PCM while the engine operates. As the intensity of the crystal's vibration
increases, the knock sensor output voltage also increases.
The voltage signal produced by the knock sensor increases with the amplitude of vibration. The
PCM receives the knock sensor voltage signal as an input. If the signal rises above a
predetermined level, the PCM will store that value in memory and retard ignition timing to reduce
engine knock. If the knock sensor voltage exceeds a preset value, the PCM retards ignition timing
for all cylinders. It is not a selective cylinder retard.
The PCM ignores knock sensor input during engine idle conditions. Once the engine speed
exceeds a specified value, knock retard is allowed.
Knock retard uses its own short term and long term memory program.
Long term memory stores previous detonation information in its battery-backed RAM. The
maximum authority that long term memory has over timing retard can be calibrated.
NOTE: Over or under tightening the sensor mounting bolts will affect knock sensor performance,
possibly causing improper spark control. Always use the specified torque when installing the knock
sensors.
Short term memory is allowed to retard timing up to a preset amount under all operating conditions
(as long as rpm is above the minimum rpm) except at Wide Open Throttle (WOT). The PCM, using
short term memory, can respond quickly to retard timing when engine knock is detected. Short term
memory is lost any time the ignition key is turned off.

Manifold Pressure/Vacuum Sensor: Description and Operation
The Manifold Absolute Pressure (MAP) sensor is mounted to the front of the intake manifold air
plenum box.
The MAP sensor is used as an input to the Powertrain Control Module (PCM). It contains a silicon
based sensing unit to provide data on the manifold vacuum that draws the air/fuel mixture into the
combustion chamber. The PCM requires this information to determine injector pulse width and
spark advance. When manifold absolute pressure (MAP) equals Barometric pressure, the pulse
width will be at maximum.
A 5 volt reference is supplied from the PCM and returns a voltage signal to the PCM that reflects
manifold pressure. The zero pressure reading is 0.5V and full scale is 4.5V. For a pressure swing
of 0-15 psi, the voltage changes 4.0V. To operate the sensor, it is supplied a regulated 4.8 to 5.1
volts. Ground is provided through the low-noise, sensor return circuit at the PCM.
The MAP sensor input is the number one contributor to fuel injector pulse width. The most
important function of the MAP sensor is to determine barometric pressure. The PCM needs to
know if the vehicle is at sea level or at a higher altitude, because the air density changes with
altitude. It will also help to correct for varying barometric pressure. Barometric pressure and altitude
have a direct inverse correlation; as altitude goes up, barometric goes down. At key-on, the PCM
powers up and looks at MAP voltage, and based upon the voltage it sees, it knows the current
barometric pressure (relative to altitude). Once the engine starts, the PCM looks at the voltage
again, continuously every 12 milliseconds, and compares the current voltage to what it was at
key-on. The difference between current voltage and what it was at key-on, is manifold vacuum.
During key-on (engine not running) the sensor reads (updates) barometric pressure. A normal
range can be obtained by monitoring a known good sensor. As the altitude increases, the air
becomes thinner (less oxygen). If a vehicle is started and driven to a very different altitude than
where it was at key-on, the barometric pressure needs to be updated. Any time the PCM sees
Wide Open Throttle (WOT), based upon Throttle Position Sensor (TPS) angle and RPM, it will
update barometric pressure in the MAP memory cell. With periodic updates, the PCM can make its
calculations more effectively.
The PCM uses the MAP sensor input to aid in calculating the following:
- Manifold pressure
- Barometric pressure
- Engine load
- Injector pulse-width
- Spark-advance programs
- Shift-point strategies (certain automatic transmissions only)
- Idle speed
- Decel fuel shutoff
The MAP sensor signal is provided from a single piezoresistive element located in the center of a
diaphragm. The element and diaphragm are both made of silicone. As manifold pressure changes,
the diaphragm moves causing the element to deflect, which stresses the silicone. When silicone is
exposed to stress, its resistance changes. As manifold vacuum increases, the MAP sensor input
voltage decreases proportionally. The sensor also contains electronics that condition the signal and
provide temperature compensation.
The PCM recognizes a decrease in manifold pressure by monitoring a decrease in voltage from the
reading stored in the barometric pressure memory cell. The MAP sensor is a linear sensor;
meaning as pressure changes, voltage changes proportionately. The range of voltage output from
the sensor is usually between 4.6 volts at sea level to as low as 0.3 volts at 26 in. of Hg. Barometric
pressure is the pressure exerted by the atmosphere upon an

object. At sea level on a standard day, no storm, barometric pressure is approximately 29.92 in Hg.
For every 100 feet of altitude, barometric pressure drops 0.10 in. Hg. If a storm goes through, it can
change barometric pressure from what should be present for that altitude. You should know what
the average pressure and corresponding barometric pressure is for your area.

Power Steering Pressure Switch: Description and Operation
SWITCH-POWER STEERING PRESSURE
DESCRIPTION
A pressure sensing switch is used in the power steering system. It is mounted on the high-pressure
steering hose. This switch will only be used with on HD vehicles with the 5.7L engines. There is no
pressure switch used for the 3.7L, 4.7L, 5.9L engines or the 5.7L LD vehicle pump.
OPERATION
The switch is used on the 5.7L V-8 engines HD vehicles only.
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high steering pump load and low engine rpm; such as
during parking maneuvers. The PCM increases the idle speed through the Idle Air Control (IAC)
motor. This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the Normally
Closed (NC) switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

Transmission Position Switch/Sensor: Description and Operation
SENSOR-TRANSMISSION RANGE
DESCRIPTION
The Transmission Range Sensor (TRS) is part of the solenoid module, which is mounted to the top
of the valve body inside the transmission. The Transmission Range Sensor (TRS) has five switch
contact pins that: ^
Determine shift lever position
^ Supply ground to the Starter Relay in Park and Neutral only.
^ Supply +12 V to the backup lamps in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

Catalytic Converter: Description and Operation
CONVERTER - CATALYTIC
DESCRIPTION
WARNING: THE NORMAL OPERATING TEMPERATURE OF THE EXHAUST SYSTEM IS VERY
HIGH. THEREFORE, NEVER WORK AROUND OR ATTEMPT TO SERVICE ANY PART OF THE
EXHAUST SYSTEM UNTIL IT IS COOLED. SPECIAL CARE SHOULD BE TAKEN WHEN
WORKING NEAR THE CATALYTIC CONVERTER. THE TEMPERATURE OF THE CONVERTER
RISES TO A HIGH LEVEL AFTER A SHORT PERIOD OF ENGINE OPERATION TIME.
CAUTION: DO NOT remove spark plug wires from plugs or by any other means short out cylinders.
Failure of the catalytic converter can occur due to a temperature increase caused by unburned fuel
passing through the converter.
The stainless steel catalytic converter body is designed to last the life of the vehicle. Excessive
heat can result in bulging or other distortion, but excessive heat will not be the fault of the
converter. If unburned fuel enters the converter, overheating may occur. If a converter is
heat-damaged, correct the cause of the damage at the same time the converter is replaced. Also,
inspect all other components of the exhaust system for heat damage.
Unleaded gasoline must be used to avoid contaminating the catalyst core.
50 State emission vehicles incorporate two mini catalytic converters located after the exhaust
manifolds and before the inline catalytic converter.
OPERATION
The catalytic converter captures and burns any unburned fuel mixture exiting the combustion
chambers during the exhaust stroke of the engine. This process aids in reducing emissions output.

Canister Purge Solenoid: Description and Operation
The duty cycle EVAP canister purge solenoid is located in the engine compartment. It is attached
to the side of the Power Distribution Center (PDC).
The Powertrain Control Module (PCM) operates the solenoid.
During the cold start warm-up period and the hot start time delay, the PCM does not energize the
solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during
open loop operation.
The engine enters closed loop operation after it reaches a specified temperature and the time delay
ends. During closed loop operation, the PCM energizes and de-energizes the solenoid 5 or 10
times per second, depending upon operating conditions. The PCM varies the vapor flow rate by
changing solenoid pulse width. Pulse width is the amount of time the solenoid energizes. The PCM
adjusts solenoid pulse width based on engine operating condition.

NOTE:
This bulletin applies to all vehicles equipped with a gasoline engine.
DISCUSSION:
Customer may report that the vehicle is hard to fill with fuel or that the fuel pump nozzle shuts off
repeatedly while trying to fill vehicle.
This customer complaint can occur due to a number of different causes. The fuel tank is the least
likely cause of this condition. The following Diagnostic procedure can be used to diagnose the
issues.
DIAGNOSIS:
1. Is the vehicle a LX/LE/LC/L2?
a. Yes >> proceed to Step # 2
b. No >> proceed to Step # 4
2. Idle the vehicle 60 to 90 seconds upon stopping.
3. Does tank refill properly?
a. No >> proceed to Step # 4

driven aggressively. This is due to the fact that
on the LX/LE/LC/L2 the fuel tank is a unique saddle tank design and needs 30 to 60 seconds while
the engine is running to level the fuel in both half's of the fuel tank. Allowing the vehicle to idle for
this amount of time will let the fuel pump transfer fuel to the left side tank, opening the control valve
and allowing normal fuel filling.
4. Disconnect the vapor recirculation tube at the fuel tank.
5. Attempt to refill fuel tank.
6. Does tank refill properly?
a. Yes >> Proceed to Step # 7
b. No >> Proceed to Step # 11.

NOTE:
This bulletin applies to all vehicles equipped with a gasoline engine.
DISCUSSION:
Customer may report that the vehicle is hard to fill with fuel or that the fuel pump nozzle shuts off
repeatedly while trying to fill vehicle.
This customer complaint can occur due to a number of different causes. The fuel tank is the least
likely cause of this condition. The following Diagnostic procedure can be used to diagnose the
issues.
DIAGNOSIS:
1. Is the vehicle a LX/LE/LC/L2?
a. Yes >> proceed to Step # 2
b. No >> proceed to Step # 4
2. Idle the vehicle 60 to 90 seconds upon stopping.
3. Does tank refill properly?
a. No >> proceed to Step # 4

driven aggressively. This is due to the fact that
on the LX/LE/LC/L2 the fuel tank is a unique saddle tank design and needs 30 to 60 seconds while
the engine is running to level the fuel in both half's of the fuel tank. Allowing the vehicle to idle for
this amount of time will let the fuel pump transfer fuel to the left side tank, opening the control valve
and allowing normal fuel filling.
4. Disconnect the vapor recirculation tube at the fuel tank.
5. Attempt to refill fuel tank.
6. Does tank refill properly?
a. Yes >> Proceed to Step # 7
b. No >> Proceed to Step # 11.

Leak Detection Pump: Description and Operation Leak Detection Pump
Vehicles equipped with JTEC engine control modules use a leak detection pump. Vehicles
equipped with NGC engine control modules use an NVLD pump. Refer to Natural Vacuum - Leak
Detection (NVLD) for additional information.
The evaporative emission system is designed to prevent the escape of fuel vapors from the fuel
system. Leaks in the system, even small ones, can allow fuel vapors to escape into the
atmosphere. Government regulations require onboard testing to make sure that the evaporative
(EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and
blockage. It also performs self-diagnostics. During self-diagnostics, the Powertrain Control Module
(PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first
checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to
pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that
leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP
as it tries to maintain pressure in the system.
EVAP LEAK DETECTION SYSTEM COMPONENTS
Service Port: Used with special tools like the Miller Evaporative Emissions Leak Detector (EELD) to
test for leaks in the system. EVAP Purge Solenoid: The PCM uses the EVAP purge solenoid to
control purging of excess fuel vapors stored in the EVAP canister. It remains closed during leak
testing to prevent loss of pressure. EVAP Canister: The EVAP canister stores fuel vapors from the
fuel tank for purging. EVAP Purge Orifice: Limits purge volume. EVAP System Air Filter: Provides
air to the LDP for pressurizing the system. It filters out dirt while allowing a vent to atmosphere for
the EVAP system.
The main purpose of the LDP is to pressurize the fuel system for leak checking. It closes the EVAP
system vent to atmospheric pressure so the system can be pressurized for leak testing. The
diaphragm is powered by engine vacuum. It pumps air into the EVAP system to develop a pressure
of about 7.5" H2O (1/4) psi. A reed switch in the LDP allows the PCM to monitor the position of the
LDP diaphragm. The PCM uses the reed switch input to monitor how fast the LDP is pumping air
into the EVAP system. This allows detection of leaks and blockage. The LDP assembly consists of
several parts. The solenoid is controlled by the PCM, and it connects the upper pump cavity to
either engine vacuum or atmospheric pressure. A vent valve closes the EVAP system to
atmosphere, sealing the system during leak testing. The pump section of the LDP consists of a
diaphragm that moves up and down to bring air in through the air filter and inlet check valve, and
pump it out through an outlet check valve into the EVAP system. The diaphragm is pulled up by
engine vacuum, and pushed down by spring pressure, as the LDP solenoid turns on and off. The
LDP also has a magnetic reed switch to signal diaphragm position to the PCM. When the
diaphragm is down, the switch is closed, which sends a 12 V (system voltage) signal to the PCM.
When the diaphragm is up, the switch is open, and there is no voltage sent to the PCM. This allows
the PCM to monitor LDP pumping action as it turns the LDP solenoid on and off.
LDP AT REST (NOT POWERED)
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak
Detection Pump, Evaporative System > Component Information > Description and Operation > Leak Detection Pump >
Page 3276
When the LDP is at rest (no electrical/vacuum) the diaphragm is allowed to drop down if the
internal (EVAP system) pressure is not greater than the return spring. The LDP solenoid blocks the
engine vacuum port and opens the atmospheric pressure port connected through the EVAP system
air filter. The vent valve is held open by the diaphragm. This allows the canister to see atmospheric
pressure.
DIAPHRAGM UPWARD MOVEMENT
When the PCM energizes the LDP solenoid, the solenoid blocks the atmospheric port leading
through the EVAP air filter and at the same time opens the engine vacuum port to the pump cavity
above the diaphragm. The diaphragm moves upward when vacuum above the diaphragm exceeds
spring force. This upward movement closes the vent valve. It also causes low pressure below the
diaphragm, unseating the inlet check valve and allowing air in from the EVAP air filter. When the
diaphragm completes its upward movement, the LDP reed switch turns from closed to open.
DIAPHRAGM DOWNWARD MOVEMENT
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak
Detection Pump, Evaporative System > Component Information > Description and Operation > Leak Detection Pump >
Page 3277
Based on reed switch input, the PCM de-energizes the LDP solenoid, causing it to block the
vacuum port, and open the atmospheric port. This connects the upper pump cavity to atmosphere
through the EVAP air filter. The spring is now able to push the diaphragm down. The downward
movement of the diaphragm closes the inlet check valve and opens the outlet check valve pumping
air into the evaporative system. The LDP reed switch turns from open to closed, allowing the PCM
to monitor LDP pumping (diaphragm up/down) activity. During the pumping mode, the diaphragm
will not move down far enough to open the vent valve. The pumping cycle is repeated as the
solenoid is turned on and off. When the evaporative system begins to pressurize, the pressure on
the bottom of the diaphragm will begin to oppose the spring pressure, slowing the pumping action.
The PCM watches the time from when the solenoid is de-energized, until the diaphragm drops
down far enough for the reed switch to change from opened to closed. If the reed switch changes
too quickly, a leak may be indicated. The longer it takes the reed switch to change state, the tighter
the evaporative system is sealed. If the system pressurizes too quickly, a restriction somewhere in
the EVAP system may be indicated.
PUMPING ACTION
Action : During portions of this test, the PCM uses the reed switch to monitor diaphragm
movement. The solenoid is only turned on by the PCM after the reed switch changes from open to
closed, indicating that the diaphragm has moved down. At other times during the test, the PCM will
rapidly cycle the LDP solenoid on and off to quickly pressurize the system. During rapid cycling, the
diaphragm will not move enough to change the reed switch state. In the state of rapid cycling, the
PCM will use a fixed time interval to cycle the solenoid. If the system does not pass the EVAP Leak
Detection Test, the following DTCs may be set:
- P0442 - EVAP LEAK MONITOR 0.040 inches LEAK DETECTED
- P0455 - EVAP LEAK MONITOR LARGE LEAK DETECTED

Leak Detection Pump: Description and Operation Natural Vac Leak Detection
Vehicles equipped with an NGC Powertrain Control Module (PCM) use a Natural Vacuum Leak
Detection (NVLD) pump and system. Vehicles equipped with a JTEC PCM use an LDP (Leak
Detection Pump). Refer to Leak Detection Pump (LDP) for additional information.
The NVLD pump is located in the same area as the leak detection pump. Refer to NVLD
Removal/Installation for additional information.
The Natural Vacuum Leak Detection (NVLD) system is the new generation evaporative leak
detection system that will first be used on vehicles equipped with the Next Generation Controller
(NGC). This new system replaces the leak detection pump as the method of evaporative system
leak detection. This is to detect a leak equivalent to a 0.020 inches (0.5 mm) hole. This system has
the capability to detect holes of this size very dependably.
The basic leak detection theory employed with NVLD is the "Gas Law". This is to say that the
pressure in a sealed vessel will change if the temperature of the gas in the vessel changes. The
vessel will only see this effect if it is indeed sealed. Even small leaks will allow the pressure in the
vessel to come to equilibrium with the ambient pressure. In addition to the detection of very small
leaks, this system has the capability of detecting medium as well as large evaporative system
leaks.
A vent valve seals the canister vent during engine off conditions. If the vapor system has a leak of
less than the failure threshold, the evaporative system will be pulled into a vacuum, either due to
the cool down from operating temperature or diurnal ambient temperature cycling. The diurnal
effect is considered one of the primary contributors to the leak determination by this diagnostic.
When the vacuum in the system exceeds about 1 inches H2O (0.25 KPA), a vacuum switch closes.
The switch closure sends a signal to the NGC. The NGC, via appropriate logic strategies, utilizes
the switch signal, or lack thereof, to make a determination of whether a leak is present.
The NVLD device is designed with a normally open vacuum switch, a normally closed solenoid,
and a seal, which is actuated by both the solenoid and a diaphragm. The NVLD is located on the
atmospheric vent side of the canister. The NVLD assembly may be mounted on top of the canister
outlet, or in-line between the canister and atmospheric vent filter. The normally open vacuum
switch will close with about 1 inches H2O (0.25 KPA) vacuum in the evaporative system. The
diaphragm actuates the switch. This is above the opening point of the fuel inlet check valve in the
fill tube so cap off leaks can be detected. Submerged fill systems must have recirculation lines that
do not have the in-line normally closed check valve that protects the system from failed nozzle
liquid ingestion, in order to detect cap off conditions.
The normally closed valve in the NVLD is intended to maintain the seal on the evaporative system
during the engine off condition. If vacuum in the evaporative system exceeds 3 inches to 6 inches
H2O (0.75 to 1.5 KPA), the valve will be pulled off the seat, opening the seal. This will protect the
system from excessive vacuum as well as allowing sufficient purge flow in the event that the
solenoid was to become inoperative.
The solenoid actuates the valve to unseal the canister vent while the engine is running. It also will
be used to close the vent during the medium and large leak tests and during the purge flow check.
This solenoid requires an initial 1.5 amps of current to pull the valve open, but after 100
milli-seconds, will be duty cycled down to an average of about 150 mA for the remainder of the
drive cycle.
Another feature in the device is a diaphragm that will open the seal in the NVLD with pressure in
the evaporative system. The device will "blow off' at about 0.5 inches H2O (0.12 KPA) pressure to
permit the venting of vapors during refueling. An added benefit to this is that it will also allow the
tank to "breathe" during increasing temperatures, thus limiting the pressure in the tank to this low
level. This is beneficial because the induced vacuum during a subsequent declining temperature
will achieve the switch closed (pass threshold) sooner than if the tank had to decay from a built up
pressure.
The device itself has 3 wires: Switch sense, solenoid driver and ground. It also includes a resistor
to protect the switch from a short to battery or a short to ground. The NGC utilizes a high-side
driver to energize and duty-cycle the solenoid.

Refueling Vapor Recovery System > System Information > Description and Operation
Refueling Vapor Recovery System: Description and Operation
The ORVR (On-Board Refueling Vapor Recovery) system consists of a unique fuel tank, flow
management valve, fluid control valve, one-way check valve and vapor canister.
The ORVR (On-Board Refueling Vapor Recovery) system is used to remove excess fuel tank
vapors. This is done while the vehicle is being refueled.
Fuel flowing into the fuel filler tube (approx. 1 inches I.D.) creates an aspiration effect drawing air
into the fuel fill tube. During refueling, the fuel tank is vented to the EVAP canister to capture
escaping vapors. With air flowing into the filler tube, there are no fuel vapors escaping to the
atmosphere. Once the refueling vapors are captured by the EVAP canister, the vehicle's computer
controlled purge system draws vapor out of the canister for the engine to burn. The vapor flow is
metered by the purge solenoid so that there is no, or minimal impact on driveability or tailpipe
emissions.
As fuel starts to flow through the fuel fill tube, it opens the normally closed check valve and enters
the fuel tank. Vapor or air is expelled from the tank through the control valve and on to the vapor
canister. Vapor is absorbed in the EVAP canister until vapor flow in the lines stops. This stoppage
occurs following fuel shut-off, or by having the fuel level in the tank rise high enough to close the
control valve. This control valve contains a float that rises to seal the large diameter vent path to
the EVAP canister. At this point in the refueling process, fuel tank pressure increases, the check
valve closes (preventing liquid fuel from spiting back at the operator), and fuel then rises up the fuel
filler tube to shut off the dispensing nozzle.

EGR Valve: Description and Operation
The electronic EGR valve and solenoid assembly (2) is attached to the front of the right cylinder
head. An exhaust gas routing tube (4) connects the EGR valve to the intake manifold.
Exhaust gas recirculation flow is determined by the Powertrain Control Module (PCM) and is
controlled by an electronic EGR valve assembly. For a given set of conditions, the PCM knows the
ideal exhaust gas recirculation flow to optimize NOx and fuel economy as a function of the pintle
position. Pintle position is obtained from the position sensor. The PCM adjusts the duty cycle of
128 Hz power supplied to the solenoid coil to obtain the correct position.
The electronic EGR valve assembly consists of a pintle, valve seat, and housing which contains
and regulates exhaust gas flow. An armature, return spring, and solenoid coil provide the operating
force to regulate exhaust gas flow by changing the pintle position. The solenoid coil assembly is
wired in parallel with a diode that connects two internal connectors.

- tubes and hoses to connect the system components.
Fig.15 Typical Closed Crankcase Ventilation System
The PCV system operates by engine intake manifold vacuum. Filtered air is routed into the
crankcase through the air cleaner hose. The metered air, along with crankcase vapors, are drawn
through the PCV valve and into a passage in the intake manifold. The PCV system manages
crankcase pressure and meters blow by gases to the intake system, reducing engine sludge
formation.
Fig.16 Engine Off Or Engine Backfire - No Vapor Flow
The PCV valve contains a spring loaded plunger. This plunger meters the amount of crankcase
vapors routed into the combustion chamber based on intake manifold vacuum.
When the engine is not operating or during an engine pop-back, the spring forces the plunger back
against the seat. This will prevent vapors from flowing through the valve.

During periods of high manifold vacuum, such as idle or cruising speeds, vacuum is sufficient to
completely compress spring. It will then pull the plunger to the top of the valve. In this position there
is minimal vapor flow through the valve.

The plastic fuel tank filler tube cap is threaded onto the end of the fuel fill tube. Certain models are
equipped with a 1/4 turn cap.
The loss of any fuel or vapor out of fuel filler tube is prevented by the use of a pressure-vacuum
fuel fill cap. Relief valves inside the cap will release fuel tank pressure at predetermined pressures.
Fuel tank vacuum will also be released at predetermined values. This cap must be replaced by a
similar unit if replacement is necessary. This is in order for the system to remain effective.
CAUTION: Remove fill cap before servicing any fuel system component to relieve tank pressure. If

Fuel Injector: Description and Operation
An individual fuel injector (1) is used for each individual cylinder.
The top (fuel entry) end of the injector (1) is attached into an opening on the fuel rail.
The fuel injectors are electrical solenoids. The injector contains a pintle that closes off an orifice at
the nozzle end. When electric current is supplied to the injector, the armature and needle move a
short distance against a spring, allowing fuel to flow out the orifice. Because the fuel is under high
pressure, a fine spray is developed in the shape of a pencil stream. The spraying action atomizes
the fuel, adding it to the air entering the combustion chamber.
The nozzle (outlet) ends of the injectors are positioned into openings in the intake manifold just
above the intake valve ports of the cylinder head. The engine wiring harness connector for each
fuel injector is equipped with an attached numerical tag (INJ 1, INJ 2 etc.). This is used to identify
each fuel injector.
The injectors are energized individually in a sequential order by the Powertrain Control Module
(PCM). The PCM will adjust injector pulse width by switching the ground path to each individual
injector on and off. Injector pulse width is the period of time that the injector is energized. The PCM
will adjust injector pulse width based on various inputs it receives.
Battery voltage is supplied to the injectors through the ASD relay.
The PCM determines injector pulse width based on various inputs.
PCM OUTPUT
The nozzle ends of the injectors are positioned into openings in the intake manifold just above the
intake valve ports of the cylinder head. The engine wiring harness connector for each fuel injector
is equipped with an attached numerical tag (INJ 1, INJ 2 etc.). This is used to identify each fuel
injector with its respective cylinder number.
The injectors are energized individually in a sequential order by the Powertrain Control Module
(PCM). The PCM will adjust injector pulse width by switching the ground path to each individual
injector on and off. Injector pulse width is the period of time that the injector is energized. The PCM
will adjust injector pulse width based on various inputs it receives.

Information > Specifications > Page 3367
Battery voltage (12 volts +) is supplied to the injectors through the ASD relay. The ASD relay will
shut-down the 12 volt power source to the fuel injectors if the PCM senses the ignition is on, but
the engine is not running. This occurs after the engine has not been running for approximately 1.8
seconds.
The PCM determines injector on-time (pulse width) based on various inputs.

Fuel Pressure Regulator: Description and Operation
A combination fuel filter and fuel pressure regulator (3) is used on all engines. It is located on the
top of the fuel pump module. A separate frame mounted fuel filter is not used with any engine.
Both fuel filters (at bottom of fuel pump module and within fuel pressure regulator) are designed for
extended service. They do not require normal scheduled maintenance. Filters should only be
replaced if a diagnostic procedure indicates to do so.
Fuel Pressure Regulator Operation: The pressure regulator is a mechanical device that is not
controlled by engine vacuum or the Powertrain Control Module (PCM).
The regulator is calibrated to maintain fuel system operating pressure of approximately 58 ± 2 psi
at the fuel injectors. It contains a diaphragm, calibrated springs and a fuel return valve. The internal
fuel filter is also part of the assembly.
Fuel is supplied to the filter/regulator by the electric fuel pump through an opening tube at the
bottom of filter/regulator.
The regulator acts as a check valve to maintain some fuel pressure when the engine is not
operating. This will help to start the engine. A second check valve is located at the outlet end of the
electric fuel pump. Refer to Fuel Pump Description and Operation for more information.
If fuel pressure at the pressure regulator exceeds approximately 60 psi, an internal diaphragm
opens and excess fuel pressure is routed back into the tank through the bottom of pressure
regulator.
Both fuel filters (at bottom of fuel pump module and within fuel pressure regulator) are designed for
extended service. They do not require normal scheduled maintenance. Filters should only be
replaced if a diagnostic procedure indicates to do so.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pump Relay >
Component Information > Diagrams > Diagram Information and Instructions > Page 3394
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Component Information > Diagrams > Diagram Information and Instructions > Page 3397
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Fuel Pump Relay: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

STANDARD PROCEDURE - TESTING OF VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Fuel Pump Relay: Description and Operation
The 5-pin, 12-volt, fuel pump relay is located in the Power Distribution Center (PDC). Refer to the
label on the PDC cover for relay location.
The Powertrain Control Module (PCM) energizes the electric fuel pump through the fuel pump
relay. The fuel pump relay is energized by first applying battery voltage to it when the ignition key is
turned ON, and then applying a ground signal to the relay from the PCM.
Whenever the ignition key is turned ON, the electric fuel pump will operate. But, the PCM will
shut-down the ground circuit to the fuel pump relay in approximately 1 - 3 seconds unless the
engine is operating or the starter motor is engaged.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank > Fuel Gauge Sender >
Component Information > Diagrams > Diagram Information and Instructions > Page 3452
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Component Information > Diagrams > Diagram Information and Instructions > Page 3455
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

STANDARD PROCEDURE - TESTING OF VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

2. Connect the other lead of the voltmeter to the other side of the switch, component or circuit. 3.
Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank > Fuel Gauge Sender >
Component Information > Diagrams > Diagram Information and Instructions > Page 3471
- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank > Fuel Gauge Sender >
Component Information > Diagrams > Page 3472
Fuel Gauge Sender: Description and Operation
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant current source is supplied to the resistor track on the fuel
gauge sending unit. This is fed directly from the Powertrain Control Module (PCM).
NOTE: For diagnostic purposes, this 12V power source can only be verified with the circuit opened
(fuel pump module electrical connector unplugged). With the connectors plugged, output voltages
will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about 8.6 volts at EMPTY for
Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The resistor track is used to
vary the voltage (resistance) depending on fuel tank float level. As fuel level increases, the float
and arm move up, which decreases voltage. As fuel level decreases, the float and arm move down,
which increases voltage. The varied voltage signal is returned back to the PCM through the sensor
return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/ setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

NOTE:
This bulletin applies to all vehicles equipped with a gasoline engine.
DISCUSSION:
Customer may report that the vehicle is hard to fill with fuel or that the fuel pump nozzle shuts off
repeatedly while trying to fill vehicle.
This customer complaint can occur due to a number of different causes. The fuel tank is the least
likely cause of this condition. The following Diagnostic procedure can be used to diagnose the
issues.
DIAGNOSIS:
1. Is the vehicle a LX/LE/LC/L2?
a. Yes >> proceed to Step # 2
b. No >> proceed to Step # 4
2. Idle the vehicle 60 to 90 seconds upon stopping.
3. Does tank refill properly?
a. No >> proceed to Step # 4
b. Yes >> Inform the customer to idle the vehicle for 60 to 90 seconds upon stopping if vehicle was
driven aggressively. This is due to the fact that
on the LX/LE/LC/L2 the fuel tank is a unique saddle tank design and needs 30 to 60 seconds while
the engine is running to level the fuel in both half's of the fuel tank. Allowing the vehicle to idle for
this amount of time will let the fuel pump transfer fuel to the left side tank, opening the control valve
and allowing normal fuel filling.
4. Disconnect the vapor recirculation tube at the fuel tank.
5. Attempt to refill fuel tank.
6. Does tank refill properly?
a. Yes >> Proceed to Step # 7
b. No >> Proceed to Step # 11.
7. Reconnect the vapor recirculation tube at the fuel tank.
8. Disconnect the other end of the vapor recirculation tube at the fuel filler tube.
9. Attempt to refill fuel tank.
10. Does tank refill properly?
a. Yes >> Replace fuel filler tube.
b. No >> Replace the vapor recirculation tube.

Main Relay (Computer/Fuel System): Description and Operation PCM Output
The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power Distribution Center
(PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit on and off.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if:
- the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.

Main Relay (Computer/Fuel System): Description and Operation ASD Sense - PCM Input
A 12 volt signal at this input indicates to the PCM that the ASD has been activated. The relay is
used to connect the oxygen sensor heater element, ignition coil and fuel injectors to 12 volt +
power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Main Relay (Computer/Fuel System): Testing and Inspection
ASD AND FUEL PUMP RELAYS
The following description of operation and tests apply only to the Automatic Shutdown (ASD) and
fuel pump relays. The terminals on the bottom of each relay are numbered. Two different types of
relays may be used, or.
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays,
terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to
terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the
circuit. Terminal 87A is the center terminal on the relay.
- When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30.
This is the On position. Terminal 87 supplies voltage to the rest of the circuit.
The following procedure applies to the ASD and fuel pump relays.
1. Remove relay from connector before testing. 2. With the relay removed from the vehicle, use an
ohmmeter to check the resistance between terminals 85 and 86. The resistance should be 75
ohms
+/- 5 ohms.
3. Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity
between terminals 30 and 87A. 4. Connect the ohmmeter between terminals 87 and 30. The
ohmmeter should not show continuity at this time. 5. Connect one end of a jumper wire (16 gauge
or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12
volt power source.
6. Connect one end of another jumper wire (16 gauge or smaller) to the power side of the 12 volt
power source. Do not attach the other end of the
jumper wire to the relay at this time.
WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS
TEST. DAMAGE TO OHMMETER MAY RESULT.
7. Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The
ohmmeter should now show continuity between relay
terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and
30.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Delivery and Air Induction > Fuel Pump Relay > Component Information > Diagrams > Diagram Information and Instructions
> Page 3515
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagrams may appear to be

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

> Page 3518
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Fuel Pump Relay: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Fuel Pump Relay: Description and Operation
The 5-pin, 12-volt, fuel pump relay is located in the Power Distribution Center (PDC). Refer to the
label on the PDC cover for relay location.
The Powertrain Control Module (PCM) energizes the electric fuel pump through the fuel pump
relay. The fuel pump relay is energized by first applying battery voltage to it when the ignition key is
turned ON, and then applying a ground signal to the relay from the PCM.
Whenever the ignition key is turned ON, the electric fuel pump will operate. But, the PCM will
shut-down the ground circuit to the fuel pump relay in approximately 1 - 3 seconds unless the
engine is operating or the starter motor is engaged.

Main Relay (Computer/Fuel System): Description and Operation PCM Output
The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power Distribution Center
(PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit on and off.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if:
- the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.

Main Relay (Computer/Fuel System): Description and Operation ASD Sense - PCM Input
A 12 volt signal at this input indicates to the PCM that the ASD has been activated. The relay is
used to connect the oxygen sensor heater element, ignition coil and fuel injectors to 12 volt +
power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Main Relay (Computer/Fuel System): Testing and Inspection
ASD AND FUEL PUMP RELAYS
The following description of operation and tests apply only to the Automatic Shutdown (ASD) and
fuel pump relays. The terminals on the bottom of each relay are numbered. Two different types of
relays may be used, or.
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays,
terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to
terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the
circuit. Terminal 87A is the center terminal on the relay.
- When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30.
This is the On position. Terminal 87 supplies voltage to the rest of the circuit.
The following procedure applies to the ASD and fuel pump relays.
1. Remove relay from connector before testing. 2. With the relay removed from the vehicle, use an
ohmmeter to check the resistance between terminals 85 and 86. The resistance should be 75
ohms
+/- 5 ohms.
3. Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity
between terminals 30 and 87A. 4. Connect the ohmmeter between terminals 87 and 30. The
ohmmeter should not show continuity at this time. 5. Connect one end of a jumper wire (16 gauge
or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12
volt power source.
6. Connect one end of another jumper wire (16 gauge or smaller) to the power side of the 12 volt
power source. Do not attach the other end of the
jumper wire to the relay at this time.
WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS
TEST. DAMAGE TO OHMMETER MAY RESULT.
7. Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The
ohmmeter should now show continuity between relay
terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and
30.

Throttle Body: Description and Operation
The throttle body is located on the intake manifold. Fuel does not enter the intake manifold through
the throttle body. Fuel is sprayed into the manifold by the fuel injectors.
Filtered air from the air cleaner enters the intake manifold through the throttle body. The throttle
body contains an air control passage controlled by an Idle Air Control (IAC) motor. The air control
passage is used to supply air for idle conditions. A throttle valve (plate) is used to supply air for
above idle conditions.
5.7L V-8 Engine:
The throttle body on the 5.7L engine is an electrically controlled unit. A mechanical cable is not
used to connect the throttle body to the accelerator pedal . The Accelerator Pedal Position Sensor
(APPS) along with inputs from other sensors sets the throttle blade to pre-determined positions.
Except 5.7L V-8 Engine: Certain sensors are attached to the throttle body. The accelerator pedal
cable, speed control cable and transmission control cable (when equipped) are connected to the
throttle body linkage arm.
A (factory adjusted) set screw is used to mechanically limit the position of the throttle body throttle
plate. Never attempt to adjust the engine idle speed using this screw. All idle speed functions are
controlled by the PCM.

Camshaft Position Sensor: Description and Operation
The Camshaft Position Sensor (CMP) on the 5.7L V-8 engine is located below the generator on the
timing chain/case cover on the right/front side of engine.
The CMP sensor is used in conjunction with the crankshaft position sensor to differentiate between
fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective
cylinders. The sensor generates electrical pulses. These pulses (signals) are sent to the Powertrain
Control Module (PCM). The PCM will then determine crankshaft position from both the camshaft
position sensor and crankshaft position sensor.
The tonewheel (2) is located at the front of the camshaft. As the tonewheel rotates, notches (3)
pass through the sync signal generator.
When the cam gear is rotating, the sensor will detect the notches. Input voltage from the sensor to
the PCM will then switch from a low (approximately 0.3 volts) to a high (approximately 5 volts).
When the sensor detects a notch has passed, the input voltage switches back low to approximately
0.3 volts.

Crankshaft Position Sensor: Description and Operation
The Crankshaft Position (CKP) (4) sensor is mounted into the right rear side of the cylinder block. It
is positioned and bolted into a machined hole.
Engine speed and crankshaft position are provided through the CKP (Crankshaft Position) sensor.
The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The
PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this
position, along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
A tonewheel is bolted to the engine crankshaft. This tonewheel has sets of notches (3) at its outer
edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM.

Ignition Cable: Description and Operation
Spark plug cables are sometimes referred to as secondary ignition wires, or secondary ignition
cables. Plug cables are used only on the 5.7L V-8 engine.
The spark plug cables transfer electrical current from the ignition coil(s) and/or distributor, to
individual spark plugs at each cylinder. The resistive spark plug cables are of nonmetallic
construction. The cables provide suppression of radio frequency emissions from the ignition
system.

Ignition Cable: Service and Repair
REMOVAL
Spark plug cables on the 5.7L engine are paired on cylinders 1/6, 2/3, 4/7 and 5/8. Before
removing or disconnecting any spark plug cables, note their original position. Remove cables
one-at-a-time. To prevent ignition crossfire, spark plug cables MUST be placed in cable tray
(routing loom) into their original position. The cable retention clips must also be securely locked.
Before installing spark plug cables to either the spark plugs or coils, apply dielectric grease to
inside of boots.
If cable tray removal is necessary, release the 4 tray-to-manifold retention clips.
INSTALLATION
Install cables into the proper engine cylinder firing order sequence. Refer to Specifications. When
replacing the spark plug and coil cables, route the cables correctly and secure them in the proper
retainers. Failure to route the cables properly may cause the radio to reproduce ignition noise. It
could also cause cross-ignition of the plugs, or, may short-circuit the cables to ground. When
installing new cables, make sure a positive connection is made. A snap should be felt when a good
connection is made.

Ignition Coil: Description and Operation Ignition Coil
The 5.7L V-8 engine uses 8 dedicated, and individually fired coil (1) for each pair of spark plugs.
Each coil (5) is mounted directly to the top of each spark plug. Each coil is bolted (6) to the valve
cover.
The ignition system is controlled by the Powertrain Control Module (PCM) on all engines.
A "wasted spark" system is used on the 5.7L engine combining paired, or dual-firing coils, and 2
spark plugs per cylinder. The coils and spark plugs are connected with paired, secondary
high-voltage cables.
Each cylinder is equipped with 1 dual-output coil. Meaning one coil mounts directly over one of the
dual spark plugs for 1 high-voltage output. A second high-voltage output is supplied directly from
the same coil (using a plug cable) to one of the dual spark plugs on a corresponding (paired)
cylinder on the opposite cylinder bank.
Each coil fires 2 spark plugs simultaneously on each of the cylinder banks (one cylinder on
compression stroke and one cylinder on exhaust stroke). EXAMPLE: When the #1 cylinder is on
compression stroke and ready for spark, the #1 coil will fire one of the dual spark plugs on the #1
cylinder
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information >
Description and Operation > Ignition Coil > Page 3625
(directly below the coil). The other dual spark plug on the #1 cylinder will be fired by the #6 coil. At
the same time, the #1 coil will fire a "wasted spark" to one of the dual spark plugs at the #6 cylinder
as coil #6 also fires a "wasted spark" to one of the dual spark plugs at the #6 cylinder.
The firing order is paired at cylinders 1/6, 2/3, 4/7, 5/8. Basic cylinder firing order is 1-8-3-6-5-7-2.
Battery voltage is supplied to all of the ignition coils positive terminals from the ASD relay. If the
PCM does not see a signal from the crankshaft and camshaft sensors (indicating the ignition key is
ON but the engine is not running), it will shut down the ASD circuit.
Base ignition timing is not adjustable on the 5.7L V-8 engine. By controlling the coil ground circuits,
the PCM is able to set the base timing and adjust the ignition timing advance. This is done to meet
changing engine operating conditions.
The PCM adjusts ignition timing based on inputs it receives from:
- The engine coolant temperature sensor
- The crankshaft position sensor (engine speed)
- The camshaft position sensor (crankshaft position)
- The manifold absolute pressure (MAP) sensor
- The throttle position sensor
- Transmission gear selection

Description and Operation
Ignition Relay: Description and Operation
The ignition system is controlled by the Powertrain Control Module (PCM) on all engines.
The 5.7L V-8 engine is equipped with 16 spark plugs. Two plugs are used for each cylinder. The
5.7L is also equipped with 8 separate and independent ignition coils. The one-piece coil bolts
directly to the cylinder head cover and attaches the coils secondary output terminal directly to a
spark plug using a rubber boot seal. Each coil is also equipped with a second output terminal. This
second terminal connects a conventional spark plug cable directly to a spark plug on the opposite
cylinder bank. A separate primary electrical connector is used for each coil.
Eight conventional spark plug cables are used with the 5.7L. These cables connect a coil on one
cylinder bank, directly to a spark plug on the opposite cylinder bank. The cables are placed and
routed in a special plastic loom to keep them separated. This loom is clipped to the intake manifold.
To prevent a miss-match of cables, a corresponding spark plug/coil number is displayed on each
plug cable: 1/6, 2/3, 4/7 and 5/8. These numbers can also be found on the top of the intake
manifold to the right of the throttle body.
Two knock sensors (one for each cylinder bank) are used to help control spark knock. The 5.7L
engine will not use a conventional distributor.
The ignition system consists of:
- 16 Spark Plugs (2 per cylinder)
- 8 Separate, Dual-Secondary Output, Ignition Coils
- 2 knock Sensors
- 8 Secondary Ignition Cables
- Powertrain Control Module (PCM)
- Also to be considered part of the ignition system are certain inputs from the Crankshaft Position,
Camshaft Position, Throttle Position, 2 knock and MAP Sensors

Knock Sensor: Description and Operation
The sensors are used only with 3.7L V-6, 4.7L V-8 and 5.7L V-8 engines. On 3.7L V-6 and 4.7L
V-8 engines, the 2 knock sensors are bolted into the cylinder block under the intake manifold.
On 5.7L V-8 engines, 2 knock sensors are also used. These are bolted into each side of the
cylinder block (outside) under the exhaust manifold.
3.7L V-6/4.7L V-8/5.7L V-8 Engines Only
Two knock sensors are used; one for each cylinder bank. When the knock sensor detects a knock
in one of the cylinders on the corresponding bank, it sends an input signal to the Powertrain Control
Module (PCM). In response, the PCM retards ignition timing for all cylinders by a scheduled
amount.
Knock sensors contain a piezoelectric material which constantly vibrates and sends an input
voltage (signal) to the PCM while the engine operates. As the intensity of the crystal's vibration
increases, the knock sensor output voltage also increases.
The voltage signal produced by the knock sensor increases with the amplitude of vibration. The
PCM receives the knock sensor voltage signal as an input. If the signal rises above a
predetermined level, the PCM will store that value in memory and retard ignition timing to reduce
engine knock. If the knock sensor voltage exceeds a preset value, the PCM retards ignition timing
for all cylinders. It is not a selective cylinder retard.
The PCM ignores knock sensor input during engine idle conditions. Once the engine speed
exceeds a specified value, knock retard is allowed.
Knock retard uses its own short term and long term memory program.
Long term memory stores previous detonation information in its battery-backed RAM. The
maximum authority that long term memory has over timing retard can be calibrated.
NOTE: Over or under tightening the sensor mounting bolts will affect knock sensor performance,
possibly causing improper spark control. Always use the specified torque when installing the knock
sensors.
Short term memory is allowed to retard timing up to a preset amount under all operating conditions
(as long as rpm is above the minimum rpm) except at Wide Open Throttle (WOT). The PCM, using
short term memory, can respond quickly to retard timing when engine knock is detected. Short term
memory is lost any time the ignition key is turned off.

Camshaft Position Sensor: Description and Operation
The Camshaft Position Sensor (CMP) on the 5.7L V-8 engine is located below the generator on the
timing chain/case cover on the right/front side of engine.
The CMP sensor is used in conjunction with the crankshaft position sensor to differentiate between
fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective
cylinders. The sensor generates electrical pulses. These pulses (signals) are sent to the Powertrain
Control Module (PCM). The PCM will then determine crankshaft position from both the camshaft
position sensor and crankshaft position sensor.
The tonewheel (2) is located at the front of the camshaft. As the tonewheel rotates, notches (3)
pass through the sync signal generator.
When the cam gear is rotating, the sensor will detect the notches. Input voltage from the sensor to
the PCM will then switch from a low (approximately 0.3 volts) to a high (approximately 5 volts).
When the sensor detects a notch has passed, the input voltage switches back low to approximately
0.3 volts.

Crankshaft Position Sensor: Description and Operation
The Crankshaft Position (CKP) (4) sensor is mounted into the right rear side of the cylinder block. It
is positioned and bolted into a machined hole.
Engine speed and crankshaft position are provided through the CKP (Crankshaft Position) sensor.
The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The
PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this
position, along with other inputs, to determine injector sequence and ignition timing.
The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel
within a certain distance from it.
A tonewheel is bolted to the engine crankshaft. This tonewheel has sets of notches (3) at its outer
edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the
input to the PCM.

Description and Operation
Overdrive Solenoid: Description and Operation
ASSEMBLY-TRANSMISSION SOLENOID/TRS
DESCRIPTION
The transmission solenoid/TRS assembly is internal to the transmission and mounted on the valve
body assembly. The assembly consists of six solenoids that control hydraulic pressure to the six
friction elements (transmission clutches), and the torque converter clutch. The pressure control
solenoid is located on the side of the solenoid/TRS assembly. The solenoid/TRS assembly also
contains five pressure switches that feed information to the TCM.
OPERATION SOLENOIDS
Solenoids are used to control the L/R, 2C, 4C, OD, and UD friction elements. The reverse clutch is
controlled by line pressure and the position of the manual valve in the valve body. All the solenoids
are contained within the Solenoid and Pressure Switch Assembly. The solenoid and pressure
switch assembly contains one additional solenoid, Multi-Select (MS), which serves primarily to
provide 2nd and 3rd gear limp-in operation.
The solenoids receive electrical power from the Transmission Control Relay through a single wire.
The TCM energizes or operates the solenoids individually by grounding the return wire of the
solenoid as necessary. When a solenoid is energized, the solenoid valve shifts, and a fluid
passage is opened or closed (vented or applied), depending on its default operating state. The
result is an apply or release of a frictional element.
The MS and UD solenoids are normally applied to allow transmission limp-in in the event of an
electrical failure.
The continuity of the solenoids and circuits are periodically tested. Each solenoid is turned on or off
depending on its current state. An inductive spike should be detected by the TCM during this test. If
no spike is detected, the circuit is tested again to verify the failure. In addition to the periodic
testing, the solenoid circuits are tested if a speed ratio or pressure switch error occurs.
PRESSURE SWITCHES
The TCM relies on five pressure switches to monitor fluid pressure in the L/R, 2C, 4C, UD, and OD
hydraulic circuits. The primary purpose of these switches is to help the TCM detect when clutch
circuit hydraulic failures occur. The switches close at 23 psi and open at 11 psi, and simply indicate
whether or not pressure exists. The switches are continuously monitored by the TCM for the
correct states (open or closed) in each gear as shown in the following charts 45RFE PRESSURE
SWITCH STATES and 545RFE PRESSURE SWITCH STATES:

Pressure Regulating Solenoid: Description and Operation
ASSEMBLY-TRANSMISSION SOLENOID/TRS
DESCRIPTION
The transmission solenoid/TRS assembly is internal to the transmission and mounted on the valve
body assembly. The assembly consists of six solenoids that control hydraulic pressure to the six
friction elements (transmission clutches), and the torque converter clutch. The pressure control
solenoid is located on the side of the solenoid/TRS assembly. The solenoid/TRS assembly also
contains five pressure switches that feed information to the TCM.
OPERATION SOLENOIDS
Solenoids are used to control the L/R, 2C, 4C, OD, and UD friction elements. The reverse clutch is
controlled by line pressure and the position of the manual valve in the valve body. All the solenoids
are contained within the Solenoid and Pressure Switch Assembly. The solenoid and pressure
switch assembly contains one additional solenoid, Multi-Select (MS), which serves primarily to
provide 2nd and 3rd gear limp-in operation.
The solenoids receive electrical power from the Transmission Control Relay through a single wire.
The TCM energizes or operates the solenoids individually by grounding the return wire of the
solenoid as necessary. When a solenoid is energized, the solenoid valve shifts, and a fluid
passage is opened or closed (vented or applied), depending on its default operating state. The
result is an apply or release of a frictional element.
The MS and UD solenoids are normally applied to allow transmission limp-in in the event of an
electrical failure.
The continuity of the solenoids and circuits are periodically tested. Each solenoid is turned on or off
depending on its current state. An inductive spike should be detected by the TCM during this test. If
no spike is detected, the circuit is tested again to verify the failure. In addition to the periodic
testing, the solenoid circuits are tested if a speed ratio or pressure switch error occurs.
PRESSURE SWITCHES
The TCM relies on five pressure switches to monitor fluid pressure in the L/R, 2C, 4C, UD, and OD
hydraulic circuits. The primary purpose of these switches is to help the TCM detect when clutch
circuit hydraulic failures occur. The switches close at 23 psi and open at 11 psi, and simply indicate
whether or not pressure exists. The switches are continuously monitored by the TCM for the
correct states (open or closed) in each gear as shown in the following charts 45RFE PRESSURE
SWITCH STATES and 545RFE PRESSURE SWITCH STATES:

Description and Operation
Overdrive Indicator Lamp: Description and Operation
A tow/haul indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional overdrive automatic transmission, this indicator is electronically
disabled. The tow/haul indicator consists of the text "TOW/HAUL", which appears in the lower
portion of the odometer/trip odometer indicator Vacuum Fluorescent Display (VFD) unit.
The odometer/trip odometer VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial
face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "TOW/ HAUL" appears in an amber color and at the
same lighting level as the odometer/trip odometer information when it is illuminated by the
instrument cluster electronic circuit board. The tow/haul indicator is serviced as a unit with the VFD
in the instrument cluster.
The tow/haul indicator gives an indication to the vehicle operator when the Off position of the
tow/haul switch has been selected, disabling the electronically controlled overdrive feature of the
automatic transmission. This indicator is controlled by the instrument cluster circuit board based
upon cluster programming and electronic messages received by the cluster from the Powertrain
Control Module (PCM) over the Programmable Communications Interface (PCI) data bus.
The tow/haul indicator is completely controlled by the instrument cluster logic circuit, and that logic
will only allow this indicator to operate when the instrument cluster receives a battery current input
on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
tow/haul indicator for the following reasons:
- Tow/Haul Lamp-On Message - Each time the cluster receives a tow/haul lamp-on message from
the PCM indicating that the Off position of the tow/haul switch has been selected, the tow/haul
indicator will be illuminated. The indicator remains illuminated until the cluster receives a tow/haul
lamp-off message from the PCM, or until the ignition switch is turned to the Off position, whichever
occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the tow/haul indicator will be
turned on, then off again during the VFD portion of the test to confirm the functionality of the VFD
and the cluster control circuitry.
The PCM continually monitors the tow/haul switch to determine the proper outputs to the automatic
transmission. The PCM then sends the proper tow/haul lamp-on and lamp-off messages to the
instrument cluster.
For proper diagnosis of the overdrive control system, the PCM, the PCI data bus, or the electronic
message inputs to the instrument cluster that control the tow/haul indicator, a diagnostic scan tool
is required.

Shift Indicator: Description and Operation
An electronic automatic transmission gear selector indicator is standard factory-installed equipment
on this model. However, on vehicles not equipped with an optional automatic transmission, this
indicator is electronically disabled. The gear selector indicator information is displayed in an
electronic, blue-green Vacuum-Fluorescent Display (VFD) unit. The VFD unit is soldered onto the
cluster electronic circuit board and is visible through a window with a smoked clear lens located on
the lower edge of the speedometer gauge dial face of the cluster overlay. The dark lens over the
VFD prevents the indicator from being clearly visible when it is not illuminated.
The gear selector indicator VFD displays the following characters from left to right: "P," "R," "N,"
"D," "2," and "1". Respectively, these characters represent the park, reverse, neutral, drive, second
gear, and first gear positions of the transmission gear selector lever on the steering column. The
VFD illuminates a rectangular box around the character that represents the currently selected lever
position.
During daylight hours (exterior lamps Off) the gear selector VFD is illuminated at full brightness for
clear visibility. At night (exterior lamps are On), the VFD lighting level is adjusted with the other
cluster illumination lamps using the panel lamps dimmer thumbwheel on the headlamp switch.
However, a "Parade" mode position of the panel lamps dimmer thumbwheel allows the VFD to be
illuminated at full brightness if the exterior lamps are turned On during daylight hours. The gear
selector indicator VFD is serviced as a unit with the instrument cluster.
The electronic gear selector indicator gives an indication to the vehicle operator of the transmission
gear that has been selected with the automatic transmission gear selector lever. This indicator is
controlled by the instrument cluster circuit board based upon cluster programming. The cluster
circuitry automatically configures itself for the proper transmission and automatic transmission
model based upon the hard wired transmission range sensor mux circuit input to the cluster.
The gear selector indicator information is displayed by a dedicated Vacuum Fluorescent Display
(VFD) unit soldered onto the instrument cluster electronic circuit board, and the VFD will not display
the gear selector indicator information after the ignition switch is turned to the Off position. Each
time the cluster is disconnected from battery current for more than about five minutes, it must
configure itself for the automatic transmission model that is in the vehicle once it is reconnected to
battery current. The instrument cluster circuitry configures the gear selector indicator VFD based
upon the following inputs from the transmission range sensor:
- Open Circuit - If the cluster is configured for an automatic transmission and the transmission
range sensor mux circuit is open, the cluster circuitry controls the gear selector indicator display
based upon electronic messages received from the electronic Transmission Control Module ( TCM)
over the Programmable Communications Interface (PCI) data bus. If the transmission range sensor
mux circuit is open and no electronic messages are received from the TCM within two seconds, the
instrument cluster circuitry will not display any gear selector position until the condition is resolved
or until the ignition switch is turned to the Off position, whichever occurs first.
- Resolved Circuit - If the transmission range sensor mux circuit is resolved, the cluster circuitry
controls the gear selector indicator display based upon the resistance value of the hard wired input
from the transmission range sensor. If the cluster is configured for an automatic transmission with a
transmission range sensor input and detects a short to ground or an open in the transmission
range sensor mux input, the instrument cluster circuitry will not display any gear selector position in
the VFD. The VFD display for the short-to-ground and open circuit conditions will continue until the
condition is resolved or until the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gear selector indicator
VFD will display all of its characters at once during the VFD portion of the test to confirm the
functionality of the VFD and the cluster control circuitry.
On models with a TCM, the TCM continually monitors the transmission range sensor, then sends
the proper gear selector indicator position messages to the instrument cluster. On models without a
TCM, the instrument cluster continually monitors the hard wired transmission range sensor
multiplexed input.
On models with a TCM, for proper diagnosis of the transmission range sensor, the TCM, the PCI
data bus, or the electronic message inputs to the instrument cluster that control the gear selector
indicator, a diagnostic scan tool is required.

Temperature Warning Indicator - A/T: Description and Operation
A transmission over-temperature indicator is standard equipment on all instrument clusters.
However, on vehicles not equipped with an optional automatic transmission, this indicator is
electronically disabled. This indicator is located on the left side of the instrument cluster, to the left
of the fuel gauge.
The transmission over-temperature indicator consists of a stencil-like cutout of the text "TRANS
TEMP" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. A red Light Emitting
Diode (LED) behind the cutout in the opaque layer of the overlay causes the "TRANS TEMP" text
to appear in red through the translucent outer layer of the overlay when the indicator is illuminated
from behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The
transmission over-temperature indicator is serviced as a unit with the instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
transmission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus.
The transmission over-temperature indicator Light Emitting Diode (LED) is completely controlled by
the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the
instrument cluster receives a battery current input on the fused ignition switch output (run-start)
circuit. Therefore, the LED will always be off when the ignition switch is in any position except On
or Start. The LED only illuminates when it is provided a path to ground by the instrument cluster
transistor. The instrument cluster will turn on the transmission over-temperature indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-On Message - Each time the cluster receives a trans over-temp lamp-on
message from the PCM indicating that the transmission fluid temperature is 135° C (275° F) or
higher, the indicator will be illuminated and a single chime tone is sounded. The indicator remains
illuminated until the cluster receives a trans over-temp lamp-off message from the PCM, or until the
ignition switch is turned to the Off position, whichever occurs first. The chime tone feature will only
repeat during the same ignition cycle if the transmission over-temperature indicator is cycled off
and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the transmission
over-temperature indicator will be turned on, then off again during the bulb check portion of the test
to confirm the functionality of the LED and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition. The PCM then sends the proper trans over-temp lamp-on or lamp-off
messages to the instrument cluster. If the instrument cluster turns on the transmission
over-temperature indicator due to a high transmission oil temperature condition, it may indicate that
the transmission and/or the transmission cooling system are being overloaded or that they require
service. For further diagnosis of the transmission over-temperature indicator or the instrument
cluster circuitry that controls the LED.
For proper diagnosis of the transmission temperature sensor, the PCM, the PCI data bus, or the
electronic message inputs to the instrument cluster that control the transmission over-temperature
indicator, a diagnostic scan tool is required.

equipped with the optional four-wheel drive system and electronically shifted transfer case, this
indicator is electronically disabled. The service 4WD indicator consists of the text "SERV 4WD",
which appears in the lower portion of the odometer/trip odometer Vacuum Fluorescent Display
(VFD) unit.
The odometer/trip odometer VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial
face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "SERV 4WD" appears in an amber color and at the same
lighting level as the odometer/trip odometer information when it is illuminated by the instrument
cluster electronic circuit board. The service 4WD indicator is serviced as a unit with the VFD in the
instrument cluster.
The service 4WD indicator gives an indication to the vehicle operator when the Transfer Case
Control Module (TCCM) has recorded a Diagnostic Trouble Code (DTC) for an electronic transfer
case circuit or component malfunction. This indicator is controlled by the instrument cluster circuit
board based upon cluster programming and electronic messages received by the cluster from the
TCCM over the Programmable Communications Interface (PCI) data bus.
The service 4WD indicator is completely controlled by the instrument cluster logic circuit, and that
logic will only allow this indicator to operate when the instrument cluster receives a battery current
input on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
service 4WD indicator for the following reasons:
- Service 4WD Lamp-On Message - Each time the cluster receives a service 4WD lamp-on
message from the TCCM, the indicator will be illuminated. The indicator remains illuminated until
the cluster receives a service 4WD lamp-off message from the TCCM, or until the ignition switch is
turned to the Off position, whichever occurs first.
- Communication Error - If the cluster receives no messages from the TCCM for five seconds, the
service 4WD indicator is illuminated by the instrument cluster to indicate a loss of TCCM
communication. The indicator remains controlled and illuminated by the cluster until a valid
message is received from the TCCM.
- Actuator Test - Each time the cluster is put through the actuator test, the service 4WD indicator
will be turned on, then off again during the VFD portion of the test to confirm the functionality of the
VFD and the cluster control circuitry.
The TCCM continually monitors the electronic transfer case switch and circuits to determine the
condition of the system. The TCCM then sends the proper lamp-on or lamp-off messages to the
instrument cluster.
For proper diagnosis of the TCCM, the PCI data bus, or the electronic message inputs to the
instrument cluster that control the service 4WD indicator, a diagnostic scan tool is required.

Operation
Control Module: Description and Operation
The Transmission Control Module (TCM) (2) may be sub-module within the Powertrain Control
Module (PCM) (3).
Or, for vehicles with a diesel engine, the Engine Control Module (ECM) (1). The PCM, and TCM
when equipped, is located at the right rear of the engine compartment, near the right inner fender.
The Transmission Control Module (TCM) controls all electronic operations of the transmission. The
TCM receives information regarding vehicle operation from both direct and indirect inputs, and
selects the operational mode of the transmission. Direct inputs are hard wired to, and used
specifically by the TCM. Indirect inputs are shared with the TCM via the vehicle communication
bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure

Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - A/T > Control Module, A/T > Component Information > Description and
Operation > Page 3750
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request Some examples of TCM indirect outputs are:
- Transmission Temperature (to PCM)
- PRNDL Position (to cluster/CCN) In addition to monitoring inputs and controlling outputs, the TCM
has other important responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed.
BATTERY FEED
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain memory in the TCM. When the battery (B+) is disconnected, this memory is
lost. When the battery (B+) is restored, this memory loss is detected by the TCM and a Diagnostic
Trouble Code (DTC) is set.
CLUTCH VOLUME INDEXES (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur.
Gear ratios can be determined by using the Scan Tool and reading the Input/Output Speed Sensor
values in the "Monitors" display Gear ratio can be obtained by dividing the Input Speed Sensor
value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - A/T > Control Module, A/T > Component Information > Description and
Operation > Page 3751
In direct drive (3rd gear), the gear ratio changes to 1:1. The gear ratio changes as clutches are
applied and released. By monitoring the length of time it takes for the gear ratio to change following
a shift request, the TCM can determine the volume of fluid used to apply or release a friction
element.
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Certain mechanical problems within the input clutch assembly can cause inadequate or
out-of-range element volumes. Also, defective Input/Output Speed Sensors and wiring can cause
these conditions. The following chart identifies the appropriate clutch volumes and when they are
monitored/updated:
SHIFT SCHEDULES
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following:
- Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

As driving conditions change, the TCM appropriately adjusts the shift schedule. Refer to the chart
to determine the appropriate operation expected, depending on driving conditions.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - A/T > Transmission Control System Relay, A/T > Component
Information > Diagrams > Diagram Information and Instructions > Page 3758
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagrams may appear to be

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Transmission Control System Relay: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Fig.7 Testing For Voltage Potential
STANDARD PROCEDURE - TESTING OF VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Transmission Control System Relay: Description and Operation Relay-Transmission Control
RELAY-TRANSMISSION CONTROL 45RFE/545RFE
DESCRIPTION
NOTE: The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power
to the solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off", no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Control Module: Description and Operation
The Transfer Case Control Module (TCCM) (2) is a microprocessor-based assembly, controlling
the 4X4 transfer case shift functions via the actuation of a shift motor and utilizing the feedback of a
mode sensor assembly. Communication is via the PCI serial bus. Inputs include user selectable
4X4 modes that include 2WD, AWD, 4HI, 4LO, and Neutral. The logic and driver circuitry is
contained in a molded plastic housing with an embedded heat-sink and is located behind the left
side of the lower instrument panel (1).
The Transfer Case Control Module (TCCM) utilizes the input from the transfer case mounted mode
sensor, the instrument panel mounted selector switch, and the following information from the
vehicle's PCI serial bus to determine if a shift is allowed.
- Engine RPM and Vehicle Speed
- Diagnostic Requests
- Manual Transmission and Brake Applied
- PRNDL
- Ignition Status
- ABS Messages
Once the TCCM determines that a requested shift is allowed, it actuates the bi-directional shift
motor as necessary to achieve the desired transfer case operating mode. The TCCM also monitors
the mode sensor while controlling the shift motor to determine the status of the shift attempt.
Several items can cause the requested shift not to be completed. If the TCCM has recognized a
fault (DTC) of some variety, it will begin operation in one of four Functionality Levels. These levels
are:
- Level Zero - Normal Operation.
- Level One - Only Mode Shifts Are Allowed.
- Level Two - Only Mode Shifts and Shifts Into LOW Are Allowed (No Neutral Shifts Are Allowed).
- Level Three - No Shifts Are Allowed
The TCCM can also be operating in one of three possible power modes. These power modes are:
- Full Power Mode is the normal operational mode of the module. This mode is achieved by normal
PCI bus traffic being present and the ignition being in the RUN position.
- Reduced Power Mode will be entered when the ignition has been powered off. In this state, the
module will shut down power supplied to external devices, and to electronic interface inputs and
outputs. From this state the module can enter either Sleep Mode or Full Power Mode. To enter this
mode, the module must receive an ignition message denoting that the ignition is off, or not receive
any messages for 5 ± 0.5 seconds. To exit this mode, the module must receive one ignition
message that denotes that the ignition is in the RUN position.
- Sleep Mode will be entered, from the Reduced Power Mode, when no PCI traffic has been
sensed for 20 ± 1 seconds. If during Sleep Mode the module detects PCI bus traffic, it will revert to
the Reduced Power mode while monitoring for ignition messages. It will remain in this state as long
as there is traffic other than run or start messages, and will return to Sleep mode if the bus goes
without traffic for 20 ± 1 seconds.
SHIFT REQUIREMENTS
If the TCCM is in full power mode and at functionality level zero, it uses the following criteria to
determine if a shift is allowed.
If any of the driver controllable conditions are not met once the shift request is recognized, the
TCCM will solidly illuminate the source position's LED and flash the desired position's LED for all
shifts except NEUTRAL. The NEUTRAL shift LED strategy will be discussed later.
Mode shifts will be allowed regardless of transmission gear or vehicle speed, whenever the
following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- A change in the Selector switch state indicates that a mode shift has been requested.
- A valid mode sensor signal is being sensed by the TCCM.

Information > Locations > Page 3790
- Proper transmit/receive messages are occurring on the PCI bus.
- Ignition key switch is in the RUN position.
Range shifts will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- A change in the Selector Switch state indicating a range shift has been requested.
- Transmission in NEUTRAL signal must be recognized for atleast 1.5 seconds ± 100 msec.
(Automatic transmissions only)
- Proper transmit/receive messages are occurring on the PCI bus.
- Clutch signal is recognized for 500 msec ± 50 msec (Manual transmissions only).
- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position.
- A valid mode sensor signal is being sensed by the TCCM.
A shift into transfer case Neutral will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- The recessed Neutral Selection switch has been depressed continuously for 4.0 seconds ± 100
msec while all shift conditions have been continuously met.
- Transmission in NEUTRAL signal recognized from the bus. (Automatic transmissions only)
- Clutch signal is recognized from the bus (Manual transmissions only).
- Proper message transmissions/receptions are occurring on the PCI bus.
- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position, engine off.
- Foot Brake is applied.
- A valid mode sensor signal is being sensed by the TCCM.
A shift out of transfer case Neutral will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- The recessed Neutral Selection switch has been depressed continuously for 1.0 seconds ± 100
msec while all shift conditions have been continuously met.
- Transmission in NEUTRAL signal recognized from the bus.(Automatic transmissions only)
- Clutch signal is recognized from the bus (Manual transmissions only).
- Proper message transmissions/receptions are occurring on the PCI bus.
- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position.
- Foot Brake is applied.
- A valid mode sensor signal is being sensed by the TCCM.
SHIFT SEQUENCES
Once all the driver controllable conditions for the requested shift have been met, the TCCM begins
a shift timer with a maximum duration of 1 second per 'D' channel transition. If the shift timer
expires before the TCCM recognizes to correct mode sensor code, the shift is considered to have
been blocked. The blocked shift will increment the blocked shift counter by one. The TCCM
strategy for handling blocked shifts will be described later. The process the TCCM performs for the
various shifts will be described first.
RANGE AND MODE SHIFTS
The process for performing all the range and mode shifts are the same. The following steps
describe the process.
- Allow time for Selector Switch debounce; 250 msec ± 50 msec.
- Extinguish the source gear's LED while flashing desired transfer case position's LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec per 'D' channel transition in the
destination gear's direction while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Solidly illuminate the selected gear's LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 seconds ± 100 msec. per 'D'
channel. The TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the
desired position.
The exception to the preceding sequence is when a shift from 4L to 2WD/AWD is requested. If
2WD/AWD is requested from the 4L position, the transfer case is first driven to the 4H position. If
the 4H position is reached, the transfer case is then driven back to the 2WD/AWD position and the
shift is considered complete. If the transfer case does not reach any the 4H position, but is in the
2WD/AWD 'D' channel, or the 2WD/AWD between gear position on the 4H side of 2WD/AWD, the
shift is also considered complete.
SHIFT OUT OF NEUTRAL
The following steps describe the process for a shift out of NEUTRAL.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - Transfer Case > Control Module, Transfer Case > Component
Information > Locations > Page 3791
- Extinguish the Neutral LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec toward the transfer case 4H mode
position while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Extinguish the Neutral LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 ± seconds 100 msec. The
TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the desired position.
- When the Neutral button is released, if the 4H position is the desired position, the shift is
complete. Illuminate the 4H LED.
- Otherwise when the Neutral button is released, if all of the shift requirements are being met then
engage the shift motor towards the desired position for 1 second ± 100 msec per 'D' channel, (if
requirements for shifting are not met, illuminate the 4H LED and flash the destination LED as an
indication to the driver that all of the driver controllable shift conditions are not being met). If this
requires another range or mode shift, begin the range/mode shift process.
- If the desired mode sensor code is not received after the shift timer expires (i.e. a blocked or other
condition exists), refer to the Blocked Shift Strategy.
BLOCKED SHIFT STRATEGY
When a shift is commanded, the shift motor will be driven towards its destination position, except in
the case of shifting out of Neutral if 4L was selected (the transfer case will shift to the 4H position
first, before proceeding to 4L). If the shift is blocked on the way to the destination, the TCCM may
attempt to drive the motor back to the original position. This process will be allowed to occur 5
times. If the transfer case has reached a non-NEUTRAL 'D' channel during the shift re-attempts,
the LED for the achieved gear position is illuminated and the shift attempts are stopped. To
re-attempt the desired shift, the selector switch will need to be rotated to the current position until
the switch debounce timer expires then a shift will need to be requested again.
At the end of the 5th blocked attempt, the shift motor is driven towards the last known 'D' channel
position. If this motor drive allows the transfer case to reach the 2WD/AWD 'D' channel, or the
2WD/AWD between gear position on the 4H side of 2WD/AWD, the shift is considered complete
and the shift attempts are ended.
If the mode sensor is in the NEUTRAL region at the expiration of the shift timer, the TCCM will
continue to make the shift attempts according to the blocked shift strategy independent of whether
or not the driver controlled conditions are met.
For shifts from NEUTRAL, if all 5 attempts fail to reach the desired position (which by default is
4H), the motor will be driven to stall in the direction of 4H or 4L, depending on the achieved
position. If the transfer case has reached the 2WD/AWD or 4L between gear position nearest the
NEUTRAL positions and the shift conditions are no longer being met, the transfer case will be
driven toward the corresponding 'D' channel. Otherwise, the transfer case will be driven in the
direction opposite the last attempt with the desired target being 4H or 4L.
If the transfer case reaches the 2WD/AWD 'D' channel when being driven in the 4H direction, then
one final 1.0 second drive toward 4H is attempted. If the transfer case then reaches any of the 4H
positions, the shift is considered complete and the 4H LED is illuminated. If the transfer case is still
the 2WD/AWD position, the shift is considered complete and the 2WD/AWD LED is illuminated.
NOTE: If after the 5th blocked shift and reversal attempt, if the transfer case position is in the
NEUTRAL region, shift attempts will continue until a non-NEUTRAL 'D' channel is reached.
SHIFT REVERSAL TARGETS
If the shift timer expires (1 second per 'D' channel) and the transfer case has not reached the
desired position, all shifts will attempt to return to their original position with the exceptions of:
- If the intended shift is going to the High rail from Low and can't make it, but it can make the
2WD/AWD position, the motor stops at that position. The TCCM will not attempt to cross back over
NEUTRAL if it does not have to. This means that there was a block on the first attempt to go to 4H
and the transfer case has made it through NEUTRAL to a known good position, then the motor will
go back only to the 2WD/4WD position and execute the remainder of the attempts from there.
- For shifts out of NEUTRAL, any time a shift is commanded out of NEUTRAL, the system needs to
get out. The TCCM should never go to NEUTRAL unless the driver is commanding it and all
required conditions are being met
ENCODER DRIFT CORRECTION
Whenever a shift is completed, the TCCM stores the position in memory as the transfer case's
intended position. The TCCM continuously monitors the mode sensor and if the mode sensor drifts
toward into a NEUTRAL region sensor position for 2.0 seconds, the TCCM will perform a motor
drive to correct the drift. The transfer case will be driven toward the intended position for 1.0
seconds 100 msec. The TCCM will wait for 2.0 seconds ± 50 msec . and repeat the attempt to shift
to the desired position. This will continue until the intended position is reached.
SHIFT MOTOR BRAKING
Two modes of shift motor braking are employed to improve shift performance, static and dynamic.
Static shift motor braking is utilized under the
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - Transfer Case > Control Module, Transfer Case > Component
Information > Locations > Page 3792
following conditions:
- Whenever the transfer case is in the 2WD/AWD or 4L 'D' channel position.
- Whenever an invalid mode sensor code is present. Static motor braking is achieved by applying
+12V on both shift motor wires. NOTE: Static Shift Motor Braking is independent of ignition key
position.
SHIFT ATTEMPT LIMIT
To protect the transfer case system, the TCCM will impose a limit on the number of shifts that can
occur over a calibrated time period. The system will monitor the number of 'D' channel segment
transitions that occur in any 30 second time period. If the number of segment transitions is 30 or
greater, the system will go into a default mode. The default mode of operation for shifting is that the
number of allowed 'D' channel transitions permitted to occur will be 3 over each 15 second ± 100
msec calibrated window of time. After 5 minutes ± 100 msec, the motor can be assumed to have
cooled down and the system will revert to normal operation. The following rules also apply to the
shift limit:
- The attempt limit will not prevent shifts coming out of NEUTRAL, they will be allowed regardless
of the counter/timer.
- Any shift that is in progress when the counter reaches a maximum count in time will be allowed to
complete before the default mode is entered. D-channel transitions during this period will not be
counted towards the default mode limit.
- A block, regardless of the direction, whether towards destination or back towards reversal target
(shift timer expiring), will count as a value of 2 transitions towards the 30 segment transitions to go
into default mode as defined above. Current attempt limit values are 30 transitions in 30 seconds
and default mode values are 3 transitions every 15 seconds for 5 minutes.

Fluid Pressure Sensor/Switch: Description and Operation
SENSOR-LINE PRESSURE
DESCRIPTION
The TCM utilizes a closed-loop system to control transmission line pressure. The system contains
a variable force style solenoid, the Pressure Control Solenoid, mounted on the side of the solenoid
and pressure switch assembly. The solenoid is duty cycle controlled by the TCM to vent the
unnecessary line pressure supplied by the oil pump back to the sump. The system also contains a
variable pressure style sensor, the Line Pressure Sensor, which is a direct input to the TCM. The
line pressure solenoid monitors the transmission line pressure and completes the feedback loop to
the TCM. The TCM uses this information to adjust its control of the pressure control solenoid to
achieve the desired line pressure.
OPERATION
The TCM calculates the desired line pressure based upon inputs from the transmission and engine.
The TCM calculates the torque input to the transmission and uses that information as the primary
input to the calculation. The line pressure is set to a predetermined value during shifts and when
the transmission is in the PARK and NEUTRAL positions. This is done to ensure consistent shift
quality. During all other operation, the actual line pressure is compared to the desired line pressure
and adjustments are made to the pressure control solenoid duty cycle.

Overdrive Switch: Description and Operation
SWITCH-TOW/HAUL OVERDRIVE
DESCRIPTION
The tow/haul overdrive OFF (control) switch is located in the shift lever arm. The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the tow/haul overdrive
OFF mode to be entered and the Tow/Haul lamp to be illuminated. Pressing the switch a second
time causes normal overdrive operation to be restored and the tow/haul lamp to be turned off. The
tow/haul overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the tow/haul overdrive switch is turned to the OFF position, or when illuminated by the
transmission control module.

Transmission Position Switch/Sensor: Description and Operation
SENSOR-TRANSMISSION RANGE
DESCRIPTION
The Transmission Range Sensor (TRS) is part of the solenoid module, which is mounted to the top
of the valve body inside the transmission. The Transmission Range Sensor (TRS) has five switch
contact pins that: ^
Determine shift lever position
^ Supply ground to the Starter Relay in Park and Neutral only.
^ Supply +12 V to the backup lamps in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

SENSOR-INPUT SPEED
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following: ^
Transmission gear ratio
^ Speed ratio error detection
^ CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following: . Torque converter clutch slippage . Torque converter element speed ratio.

Transmission Temperature Sensor/Switch: Description and Operation
SENSOR-TRANSMISSION TEMPERATURE
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: ^
Battery (ambient) temperature
^ Engine coolant temperature
^ In-gear run time since start-up

SWITCH-SELECTOR
DESCRIPTION
The selector switch assembly (1) is mounted in the left side of the vehicle's Instrument Panel (IP)
and consists of a rotary knob connected to a resistive network for the mode and range shift
selections. Also located in this assembly is a recessed, normally open momentary switch for
making shifts into and out of transfer case NEUTRAL. A pen, or similar instrument, is used to make
a NEUTRAL shift selection, thus reducing the likelihood of an inadvertent shift request.
The selector switch also contains four light emitting diode's (LED's) to indicate the transfer case
position and whether a shift is in progress.
OPERATION
As the position of the selector switch varies, the resistance between the Mode Sensor supply
voltage pin and the Mode Sensor output will vary. Hardware, software, and calibrations within the
Transfer Case Control Module (TCCM) are provided that interpret the selector switch resistance as
given in the table below:
SELECTOR SWITCH INTERPRETATION
SELECTOR SWITCH INTERPRETATION
For resistances between the ranges B-E shown for each valid position (T-Case NEUTRAL, 4LO,
4HI, 2WD), the TCCM may interpret the resistance as: ^
either of the neighboring valid positions.
^ as an invalid fault position.
For resistances between the ranges E and F shown for 2WD and in-between positions, the TCCM
may interpret the resistance as: ^
the 2WD position.
^ an invalid fault position.
^ a valid in-between position.
For resistances between the ranges F and G shown for in-between positions and fault condition
(open), the TCCM may interpret the resistance as: ^
a valid in-between position.
^ an invalid fault position.

For resistances between the ranges A and B shown for the fault condition (short) and, T-Case
NEUTRAL, the TCCM may interpret the resistance as: ^
the T-Case NEUTRAL position.
^ an invalid fault position.
The LED's in the selector assembly are illuminated/flashed in the following manner to indicate a
particular condition or state. ^
A solidly illuminated LED indicates a successfully completed shift and the current operating mode
of the transfer case. While a shift has been requested but not yet completed, the LED for the
desired transfer case position is flashed.
^ A flashing operating mode LED for the desired gear indicates that a shift to that position has been
requested, but all of the driver controllable conditions have not been met. This is in an attempt to
notify the driver that the transmission needs to be put into NEUTRAL, the vehicle speed is too
great, or some other condition outlined (other than a diagnostic failure that would prevent this shift)
elsewhere is not met. Note that this flashing will continue indefinitely until the conditions are
eventually met, or the selector switch position is changed, or if diagnostic routines no longer allow
the requested shift.
^ If the driver attempts to make a shift into transfer case NEUTRAL, and any of the driver
controllable conditions are not met, the request will be ignored until all of the conditions are met or
until the NEUTRAL select button is released. Additionally the neutral lamp will flash, or begin to
flash while the button is depressed and operator controllable conditions are not being met. All of
the LED's except the Neutral will flash if any of the operator controllable conditions for shifting are
not met while the Neutral button is depressed. This "toggle" type of feature is necessary because
the TCCM would interpret another request immediately after the shift into transfer case NEUTRAL
has completed.
^ No LED's illuminated indicate a fault in the transfer case control system.

SENSOR-MODE
DESCRIPTION
The transfer case mode sensor (1) is an electronic device whose output can be interpreted to
indicate the shift motor shaft's rotary position. The sensor consists of a magnetic ring and four Hall
Effect Transistors to create a 4 channel digital device (non-contacting) whose output converts the
motor shaft position into a coded signal. The TCCM must supply 5VDC (+/- 0.5v) to the sensor and
monitor the shift motor position. The four channels are denoted A, B. C, and D. The sensor is
mechanically linked to the shaft of the cam which causes the transfer case shifting. The mode
sensor draws less than 53 mA.
OPERATION
During normal vehicle operation, the Transfer Case Control Module (TCCM) monitors the mode
sensor outputs at least every 250 (+/-50) milliseconds when the shift motor is stationary and 400
microseconds when the shift motor is active. A mode sensor signal between 3.8 Volts and 0.8 Volts
is considered to be undefined.
Refer to SECTOR ANGLES vs. TRANSFER CASE POSITION for the relative angles of the transfer
case shift sector versus the interpreted transfer case gear operating mode. Refer to MODE
SENSOR CHANNEL STATES for the sensor codes returned to the TCCM for each transfer case
mode sensor position. The various between gears positions can also be referred as the transfer
case's coarse position. These coarse positions come into play during shift attempts.

NOTE:
Refer to the table for specific applications.
DISCUSSION:
Mopar(R) is currently phasing out pre-programmed PCMs for the vehicles listed. New modules will
no longer be pre-programmed when received from Mopar(R). Replacement of future PCMs will
require programming utilizing the DRBIII(R) and TechCONNECT. The PCM will not operate the
engine until it is programmed. A Diagnostic Trouble Code (DTC) will be set - "not programmed".
CAUTION:
Extreme care must be taken when programming a calibration into a generic PCM. Do not randomly
select a calibration. Once a calibration is selected and programmed, the controller cannot be
reprogrammed to a different calibration. The module can only be reprogrammed to a more recent
version of that calibration.

performing this Repair Procedure. The CAB module and the PCM are connected at the same
diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB
module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is
complete turn the ignition switch to the OFF position, connect the CAB module connector, and then
check for any erroneous DTC's. If the PCM becomes "locked" during reprogramming because the
ABS CAB module connector was not disconnected, then the PCM may be recovered by following
the procedure in this NOTE.
NOTE:
Whenever a controller is programmed, the software in the DRBIII(R); must be programmed with the
latest revision level available.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted and then follow the
directions on the DRBIII(R).
1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from
the DRBIII(R) memory. To clear the memory from the MAIN MENU power up the DRBIII(R) and
then:
a. Simultaneously press the "MORE" and "YES" keys.
b. A screen will appear requesting a "COLD BOOT".
c. Follow the on screen instructions by selecting the "F4" key.
d. When the DRB III(R) reboots to the MAIN MENU, proceed to Step 2.

DISCUSSION:
NOTE:
Many of the reasons a flash reprogramming procedure may not complete are documented in this
service bulletin, but if you are constantly having issues performing the flash reprogramming
procedure using a specific DRBIII(R), it is suggested you send the DRBIII(R) in question to
SPX/Miller Special Tools for service.
Occasionally a flash update procedure may not complete properly and/or the diagnostic equipment
may lock up or become disconnected during the procedure. Flash Reprogramming is a "CRITICAL
PROCESS"; an error may result in a no-start/failed control module. Most modules, encountering an
interruption or failure while reprogramming, are recoverable; a recoverable module is not covered
under the provisions of the warranty.
This service bulletin covers items that may cause this condition, a process to restart the flash
procedure, and miscellaneous information that will help prevent needless replacement of control
modules.
GENERAL: Flash Reprogramming is only authorized by a specific SERVICE BULLETIN, or
RECALL.
Review the entire Service Bulletin/Recall prior to performing a flash reprogramming update. Often
other parts may need to be serviced, replaced, or tested, prior to flash reprogramming, and ARE
REQUIRED as part of completing the Service Bulletin/Recall.
When flashing a Powertrain Control Module (PCM) or Transmission Control Module (TCM) there
are other legal requirements with labeling issues that are included in those service bulletins.
Other non-emission related modules, such as instrument clusters and Body Control Modules
(BCMs) do not require labels.
FLASH REPROGRAMMING SEQUENCE OF EVENTS
The process of flash reprogramming is similar to flashing the BIOS on a Personal Computer.
Interruptions, voltage problems, and a variety of other outside interactions can potentially interfere
with the process. This document seeks to provide information to minimize problems associated
with vehicle control module flash reprogramming. The description that follows is for most PCMs
and some TCMs. Other modules use different initiation procedures.
The process starts by selecting an update from the TechCONNECT Client or ISIS and then
"loading" that update into the DRBIII(R). Once the flash reprogramming update is loaded into the
DRBIII(R), and before the flash reprogramming begins, the DRBIII(R) verifies that the update
loaded from the TechCONNECT Client or ISIS is the proper update for the module. This is done
using part number supersedence. This verification occurs only if an update is required, available
(on the TechCONNECT Client or ISIS) and has been selected for programming.
^ The module is then placed into "Boot Strap" programming mode by the DRBIII(R). This module
mode gives the DRBIII(R) permission and the ability to proceed with the flash reprogramming
session.
^ Next, the current part number, which resides in the module's flash memory, is stored in a "Safe
Memory" location within the module. This memory location is not affected by flash memory erasure
and reprogramming, which are to follow.
^ Once the part number is safely stored, the flash memory in the control module is erased. From
this point forward any interruption in the flash process,
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3925
will result in a Non-Responsive module (NR). A NR module is a module that is either partially
erased or partially programmed.
^ After erasure, the actual reprogramming procedure starts, and the update software is
programmed into the flash memory within the module.
^ When reprogramming is completed, the flash memory is verified through an internal process in
the DRBIII(R) using a "Check Sum". This value is compared against another value that represents
what should be in memory and when matched, verifies successful reprogramming.
^ Next, a DRBIII(R) prompt is displayed instructing that the ignition switch be turned OFF. The
module exits the "Boot Strap" mode when the switch is turned off.
^ After a slight pause, the DRBIII(R) will prompt for the ignition switch to be turned ON. The
DRBIII(R) then reads the new part number in flash memory (along with a new computer program
the new part number is placed into the module's memory). If the new part number matches the
expected part number, the flash reprogramming session has completed successfully.
SOFTWARE VERSIONS MUST BE CURRENT
Before attempting a flash reprogramming session using the TechCONNECT Client, make sure you
have the most current DRBIII(R) software installed.
To verify whether your DRBIII(R) software is current, check the upper right-hand corner of the
TechCONNECT Client screen for DRBIII(R) Available Version, DRBIII(R) Current Version.
Often, because of multiple DRBIII(R)s in the shop, not all will get updated on a timely manner. The
installed DRBIII(R) software version can generally be found at the bottom center of most screens.
Alternately the version can be checked by pressing 6, 2, 5 from the DRBIII(R) Main Menu and
comparing it to what is available from a current TechCONNECT Client as described above.
If the TechCONNECT Client is current and the DRBIII(R) is not, it may be due to the fact that the
TechCONNECT Client does not force DRBIII(R) updates for "minor" revisions. Changes and new
support are added to the Vehicle Flash application on "minor" revisions on a regular basis. This is
why your TechCONNECT Client and DRBIII(R) must have the LATEST software revisions
installed.
DO NOT PASS on the option for updating to a "minor" revision!
Major updates require the DRBIII(R) to be updated prior to allowing any flash programming.
DRBIII(R) CABLES
A NEW DRBIII(R) cable was released as an Essential Service Tool! CH7000A - 8 ft.
Cable, DRBIII(R) to OBDII (J1962) DLC Connector.
CH7000A is the required cable for ALL flash reprogramming. The older CH7000 cable can be used
for diagnostics ONLY. One (1) cable was shipped to all dealerships. Easily identified, the correct
cable has a RED connector, which plugs into the DRBIII(R).
The cable modification enhances the DRBIII(R) communication capabilities when dealing with the
flash requirements of certain controllers/ECUs affected in part by the recent changes in DLC
connector configurations.
The new cable is required for ALL flash reprogramming sessions, and can be used wherever the
previous CH700017001 cables were used.
While not recommended for flash reprogramming usage, if you require a longer cable, there is also
a 12-foot cable released under pin CH7001A
The production of the previous CH700017001 cables has ceased. All orders placed will be
superseded to part number CH7000A/CH7001A.

NOTE:
Consider all cables wear items. Always inspect for worn, damaged cables, connectors that are
damaged or do not lock securely, and all mating connections including checking for corrosion on
the pins. REPLACE ALL suspect cables. Do not use worn or damaged cables when flash
reprogramming.
Failure to use the new cable or to use a damaged cable often results in failed flash reprogramming
sessions.
The 2 door Sebring, Stratus, and Avenger coupes (supplied by MMC) generally use the CH7O1O
cable (Pre-OBDII MMC vehicles will use the CH7005 cable).
TechCONNECT CABLE (GPIB)
Replace any suspect GPIB cable.
The GPIB cable provides the connection between TechCONNECT Client and the DRBIII(R).
This cable is used by the TechCONNECT Client for vehicle part number reads and to send update
files to the DRBIII(R).
Inspect this cable for loose connections, damaged connectors or terminals, and wear and tear. If
this cable becomes disconnected during a flash session, you may have to reload the update file
that you selected on the TechCONNECT Client.
TROUBLESHOOTING CONNECTIVITY OF THE DRBIII(R) UNIT TO THE TechCONNECT
APPLICATION.
1. Turn-on the power to the DRBIII(R) unit.
2. Select option 2 "Connect to TechCONNECT" and press Enter.
3. Attach the male mini D-shell amphenol GPIB connector of the new DRBIII(R) cable (part number
CH7035B) to the DRBIII(R) unit.
4. Insure that the larger female D-shell amphenol GPIB connector of the new DRBIII(R) cable is
properly attached to the male D-shell amphenol GPIB connector on the GPIB-USB-B protocol
converter, (part number CHGPIB-B).
5. Attach the USB cable from the GPIB-USB-B protocol converter to one of the USB ports on the
rear panel of the client CPU.
6. When the cable is attached to the USB port of the CPU for the first time, Windows 2000 will
detect the device and install software for it. Please wait for 25-30 seconds to complete the
installation.

ISIS NULL MODEM CABLE
Replace any suspect null modem cables.
International (ISIS), a PC-based CD program similar to TechCONNECT Client uses a null modem
cable for vehicle part number reads and to send update files to the DRBIII(R). Inspect this cable for
loose connections, damaged connectors or terminals, and wear and tear. If this cable becomes
disconnected during a flash download session, you will have to reload the update file or files.
GENERAL NOTES FOR CABLES AND VEHICLE CONNECTIONS
Consider ALL cables to be wear items.
Many successful dealers have dedicated cables devoted to "Flash ONLY".
Always have spare CH7000A, CH7010 and CH2002 GPIB or null modem cables available.
Inspect vehicle diagnostic connectors for potential problems that might cause communication
interruptions.
There are now clip repair kits available through teamPSE to replace the retaining clips for two of
these cables. To protect the DRBIII(R) from internal damage, the clips are designed to fail at above
25 lbs. of axial force. Kits are described in the table.
It is a good practice to discard cables that have damage to the pins, cuts, corrosion, or general
damage beyond the retaining clips.

These vehicles use MMC based modules. The CH8432 Supplemental Reprogramming Tool (SRT)
was shipped as a 2001 Essential Tool. The flash reprogramming update files will be downloaded
from TechCONNECT Client to the SRT for flash reprogramming sessions on these vehicles. Users
should closely follow the instructions that come with the tool. If the tool has not been initialized,
there is a known condition where it may take up to 5 or more attempts for it to fully initialize and
become functional.
NOTE:
Once it has successfully flashed, it is initialized and no further action is required.
PREPARING TO FLASH
It is highly recommended that a sign, or other process, be used that notifies other users that a
FLASH SESSION IS IN-PROGRESS and must NOT be interrupted. Interrupting some flash
reprogramming sessions at critical junctures can render a module inoperative. Another user may
not realize that a flash session is in-progress and may disturb or disconnect the DRBIII(R) or do
something on the vehicle that could interrupt the flash process.
Before starting the flash session, read, record and erase all DTCs found on the vehicle.
Also "Cold Boot" the DRBIII(R) and download the flash since this will erase the flash file from the
DRBIII(R) memory. (To "Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the
same time. Then press "F4").
Be sure to arrange the TechCONNECT and DRBIII(R) so that no cables are stretched across an
area where someone might trip over or kick a cable. When setting up your DRBIII(R), insure that it
rests on a surface where it will not fall or be bumped during reprogramming e.g.: DRBIII's have
been known to be swept off vehicle windshields by accident when a user bumps the wiper switch).
Check User settings on the DRBIII(R). From the DRBIII(R) Main menu, press 6,1 and check to
make sure item 1. Echo on PC is set to OFF. On occasion, when Echo on PC is set to ON, flash
reprogramming errors may occur.
VEHICLE BATTERY VOLTAGE
The flash programming procedure puts a load on the electrical system that may last from five to
twenty minutes depending on the particular flash reprogramming update. Connect a battery
charger to the vehicle. Set the charger to as close to 14 volts as possible. If the charger has a
timer, set it for 30 minutes BEFORE starting a flash reprogramming session. This will help to
prevent unwanted resets by either the DRBIII(R) and/or the vehicle module that are caused by
voltage fluctuations.
Alternately, as a bare minimum, use a "Battery Jump Box" when a battery charger is unavailable to
ensure adequate and stable system voltages on the module being flash reprogrammed.

Connected/Disconnected Flash Mode Using TechCONNECT
CONNECTED MODE FLASHING USING TechCONNECT
NOTE:
Capable but not recommended.
In this mode, the DRBIII(R) remains connected to the TechCONNECT Client and the vehicle
throughout the flash session. The DRBIII(R) is connected to the TechCONNECT Client using the
GPIB (CH7035) cable and to the vehicle using the vehicle I/O cable (the CH7000A for most
vehicles).
This mode is useful when the TechCONNECT Client is next to the vehicle being flashed.
Another advantage of this mode is that you are able to determine all available flash updates for the
vehicle you are connected to by clicking on the "Read Part Number(s) From Vehicle" button.
Again, it is important that other users do not attempt to reboot or move the TechCONNECT Client
while a flash update is in-progress.
The reprogramming procedure of this mode is initiated by selecting the controller option and
clicking "Download/Update" button on the TechCONNECT client.
DISCONNECTED FLASH MODE
NOTE:
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))

Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3929
This is the preferred method.
This mode allows a user to flash a vehicle without being connected to the TechCONNECT Client.
This is a popular mode for flashing in a remote area of the service garage or in a back lot.
Before you attempt to use this mode, you must configure the DRBIII(R) for the desired update(s).
To do this, you must connect the DRBIII(R) to the TechCONNECT Client using the GPIB cable and
the CH7025 cable. It is not necessary to be connected to a vehicle. The GPIB (CH7035) cable will
be used to communicate with the TechCONNECT Client (for update file downloading) while the
CH7025 cable is used to provide power to the DRBIII(R).
After making the above connections, you are able to select one or more updates that you want to
perform. These selections are made by highlighting the desired updates and then clicking on the
"Download/Update" button by selecting the DRBIII(R) option on the TechCONNECT client.
Obviously, the DRBIII(R) does not have unlimited memory. If the file size of the selected updates
exceeds 948 KB, the "DRB Space Used" indicator (at the bottom-center of the TechCONNECT
Client screen) will change color from GREEN to RED. At this point you must de-select entries until
the indicator changes color to GREEN again.
When the updates have finished downloading, you may disconnect from the TechCONNECT Client
and take the DRBIII(R) to wherever the vehicle is located. The updates will remain in DRBIII(R)
memory for 8 hours while the DRBIII(R) is without power. If the DRBIII(R) is powered up for several
minutes before the 8 hour time period has expired, the update files will remain on the DRBIII(R) for
another 8 hours without power.
To start the actual flash process, after connecting to the vehicle in Disconnected Mode, you must
press "7 - Vehicle Flash" from the Main Menu on the DRBIII(R). Step by step instruction will follow
on the DRBIII(R) display. As with Connected Flash Mode, take the necessary precautions to insure
that others are aware of the flash session and that nothing disturbs the vehicle, DRBIII(R), or
cabling while performing the flash. Remember to use a battery charger set to 14 volts or a "battery
jump box".
Pay Attention While Performing Flash Reprogram Procedures
PAY ATTENTION WHILE PERFORMING FLASH REPROGRAMMING PROCEDURES
Before downloading the flash files, double check to see if the files that you have selected are the
appropriate ones for that vehicle. Don't forget about the "Read Part Numbers From Vehicle" option
on TechCONNECT Client, this can be of great assistance when trying to flash a module. If the files
selected don't download on the first attempt, try again.
The technician should NOT leave the vehicle when flash reprogramming a module.
Again, check to make sure that all cable connections are secure and that the DRBIII(R) rests on a
stable surface. If you are using a battery charger, insure that the settings and charging times are
correct and that the battery post clamps are securely fastened.
Read, record, and erase all DTCs found on the vehicle. Read and record the module type and part
number from the module that is to be flash reprogrammed.
Some control modules are not "abort-recovery" capable. When this is true, the scan tool will
indicate so by displaying a WARNING message prior to the start of reprogramming. For these
modules it is especially important that all precautions and procedures, outlined here, are carefully
followed.
Pay special attention to DRBIII(R) screen directions relating to key cycles. Missing a "Key ON" or
"Key OFF" can cause the module to have to be reflashed again. Due to the variety of module types
and vehicle options, you can't always anticipate key prompts, so be alert and ready to respond to
DRBIII(R) instructions.
Some screens will also instruct that certain modules, connectors or fuses be disconnected or pulled
prior to the start of reprogramming and re-installed immediately after completion. Be careful not to
anticipate the steps or order of operations for reprogramming any vehicle modules. Because of the
many possible changes that occur with each new release of scan tool software, always allow the
TSB/Recall and scan tool instructions to be your guide while performing flash reprogramming.
Flash reprogramming sessions usually range from 5 to 20 minutes. If the flash session has not
completed within 25 minutes after starting a flash reprogramming update, an error has most likely
occurred (Record the message that appears on the screen when a failure occurs). If this is the
case, or if you know that the flash process was interrupted, cycle the ignition key (OFF to the
locked position, then back ON). Reset the DRBIII(R) (power down for 4 seconds and then power
up) before attempting to restart the flash process. If the module still won't respond, turn the ignition
key off, disconnect the module from the vehicle for 2 minutes, reconnect the module, turn the
ignition key to run and try to restart the flash process again.
Regardless of what mode that you are in (Connected Flash or Disconnected Flash), if you have
tried twice (2 times) unsuccessfully to do a flash recovery and ALL DRBIII(R) instructions were
followed, perform the following:
^ Cold boot the DRBIII(R). This resets memory and removes all update files from the DRBIII(R).
(Push MORE and YES buttons at the same time, then press F4).
^ Reload the flash update file from the TechCONNECT Client.
^ If it fails to complete in the connected mode, first reboot the TechCONNECT Client before
re-attempting the flash download to the DRBIII(R).

18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3930
^ Proceed to reflash the module.
On vehicles that have multiple flash updates available, always complete and verify each flash
update before attempting the next one.
After all flash reprogramming is completed, read and erase all DTCs in all modules on the vehicle.
A variety of DTCs may be set, which are usually related to a loss of communication with the
module(s) being reprogrammed.
Verify the update by reading the new part number using the DRBIII(R). A good double check is to
read the part number using DRBIII(R) stand alone.
At times, other modules, wired in parallel, to the DLC connector have prevented flash
reprogramming sessions to be successful. After the failed attempt, review the appropriate wiring
diagram for the vehicle you are flash reprogramming and, with the key "OFF"; disconnect the other
modules and retry the flash. Complete the flash, turn the key "OFF" and reconnect any modules
that were disconnected. Refer to the "Programmable Modules" section later in this document for
more information.
Error Messages
ERROR MESSAGES
Block Echo/Compare Errors
Block Echo and Block Compare errors are often caused by voltage fluctuations, faulty I/O cables
(CH7OOOA, CH7005, CH7010) or faulty communication connections at the diagnostic connector.
Inspect for these conditions and review the sections on Vehicle Battery Voltage and Cable
recommendations.
Checksum Errors
Checksum Errors are generally caused by corrupt flash update files, which can be caused by
DRBIII(R) memory problems. If the DRBIII(R) has been without power for more than 8 hours, the
update files and system memory could be in a corrupted state. "Cold Boot" the DRBIII(R). (To
"Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the same time. Then press
"F4"). Reload the flash update file(s) from the TechCONNECT CLIENT. If it fails to complete in the
connected mode, first reboot the TechCONNECT Client before re-attempting the flash download to
the DRBIII(R). Then re-attempt the flash reprogramming process.
Enhanced and Original Abort Recovery
ENHANCED ABORT RECOVERY
Interruptions in the flash process are one of the main reasons for failed flash sessions and
non-responsive (NR) modules. Interrupting the flash process after the erase phase has started will
leave the control module in a non-functional state.
Generally, but not always, NR modules may be recovered successfully.
Briefly, abort recovery is the process used to get a NR module back to a fully functional state with
the latest software update. The technician should be familiar with the other sections in this
document and follow all DRBIII(R) user prompts carefully.
There are two methods for abort-recovery. The newer method is called "Enhanced Abort
Recovery". This is the preferred method since the original method takes several minutes longer
and requires the correct selection of module type from a list of possible PCM's or TCM's.
Starting with Release 60.1, a new useful feature was added to the flash reprogramming application
for Engine and Transmission control modules. The DRBIII(R) "writes" the YME and Controller Type
information to a "Safe Memory" location. This method allows for rapid recovery of the module part
number and minimizes errors that could otherwise be made by selecting the wrong controller type.
It also assumes that the user will attempt abort recovery for a failed flash attempt before moving to
another vehicle with the same DRBIII(R). If you need to move to another vehicle for flash
reprogramming you must erase the saved recovery information in order to successfully perform
flash reprogramming. Be careful to match the YME information displayed on the enhanced abort
recovery screen with the vehicle and module that you are attempting to recover. If you use the
recovery file on a different vehicle and module you could damage the module.
The recovery information will be displayed on your DRBIII(R), at the start of a flash session, only if
you previously encountered a problem that prevented a flash session from completing normally. If
your prior flash session was successful, the DRBIII(R) automatically erases the recovery file so that
the flash application will not show any recovery information at the start of your next flash session.
Enhanced abort recovery features:
^ Reduces the amount of time for the Module ID process.
^ Lowers the risk of possible user mistakes by presenting the user the Year, Model, Engine, and
Controller Type.
^ Currently only applicable to Engine and Transmission flash reprogramming.
^ The enhanced abort recovery file will only be erased upon a successful flash or manually by the
user.

Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3931
^ Cold booting (simultaneously pushing MORE & YES, then F4) the DRBIII(R) will not erase the
enhanced abort recovery file, but cold booting the DRBIII(R) will still erase the flash file so it can be
reloaded.
^ The user has a choice, at the start of a flash session, whether or not to use the enhanced abort
recovery feature. If the user chooses to erase the recovery file, then the DRBIII(R) will use the
original method of abort recovery.
^ Cycling the ignition key, when prompted by the DRBIII(R), is still necessary to put the controller
into bootstrap (reprogramming) mode.
ORIGINAL ABORT RECOVERY
If the choice is made to use the original method of abort recovery, a NR module is not always able
to provide the DRBIII with ID information. In this case the technician must enter this when prompted
by the DRBIII(R). Be patient when performing this process. If the module does not respond to
standard diagnostic requests, the DRBIII(R) may take several minutes before it determines that the
engine module is in a NR state. At this point, the DRBIII(R) displays the prompt "Could not
determine engine controller type. Please select from list" along with a list of possible controller
types (if the DRBIII(R) is attempting to identify a TCM, the prompt will say "trans" instead of
"engine" and list the possible trans controller types). Because of module variations, it is important
to correctly identify the PCM/TCM type so that the correct flash procedure is used. Failure to do
this will cause further problems and may damage the module. Tables are provided below to help
identify the proper module type to select. These tables correctly identify the modules that were on
the vehicles when they were built. However, some vehicles will have module types which were
superseded to a new type when a replacement part was installed (ie: EATX4 modules replaced
with an EATX4A). Correctly identify these modules using DRBIII(R) Standalone prior to attempting
flash reprogramming.
NOTE:
When instructed to turn the key to the LOCKED position, be sure that the key is not just turned to
the OFF position. The key must be rotated to the point at which it can be removed from the ignition
switch. On most vehicles the switch is on the steering column and at this position the steering
column is LOCKED. When instructed to turn the key to the RUN position, be careful not to turn the
key past this position which may engage the starter motor. This creates electrical noise which
interferes with the flash process.
General Steps for Abort Recovery
1. Review all Tips and Techniques before continuing. Pay special attention to the section on
Preparing to Flash a controller and to the Programmable Modules section.
2. Cycle the vehicle's ignition key to the LOCKED position and back to the RUN position.
3. Reset the DRBIII(R) by disconnecting the vehicle cable from the DRBIII(R) for 4 seconds and
then reconnecting the cable.
4. Depending on where the flash session was aborted, the DRBIII(R) may require that the
technician identify the control module type that was being flash reprogrammed. Use the PCM/TCM
configuration table below as a guide. This step is not necessary if using the enhanced abort
recovery method.
5. After selecting the proper control module type or choosing enhanced abort recovery, follow the
prompts that are displayed on the DRBIII(R).
NOTE:
If an error message is displayed at this point, an incorrect module type was most likely selected. If
this occurs, start the process over.
6. If the recovery process is unsuccessful, perform the following:
a. Review the TSB/Recall notice (authorizing the flash update) and all Tips and Techniques in this
document.
b. Reboot/Restart the TechCONNECT Client.
c. "Cold Boot" the DRBIII(R). (Press the MORE and YES buttons on the DRBIII(R) at the same
time, then press F4).
d. Start this process over from item # 1. If using Disconnected Mode, the flash update will have to
be reloaded from the TechCONNECT Client or ISIS DVD.

Programmable Modules
The following pages list the various modules that have flash reprogramming capability. It does not
mean that a flash is currently available. What will be described are the module types and
variations, followed by items to note, and finally, abort recovery specifics if applicable.
Powertrain Modules - Engine and Transmission
ENGINE - POWERTRAIN CONTROL MODULE (PCM)
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3936
There are a variety of Engine (PCM) modules that are flash reprogrammable. Suggestions that are
somewhat unique to each type will have comments. Prior to reprogramming a PCM, retrieve the
module information and module type using your DRBII I®. PCM information is used by many
modules. Be sure to check DIG's before and after performing all flash reprogramming event.
The DTC's associated with flash reprogramming generally relate to "lack of communication" with
the other modules during the reprogramming session.
SBEC
Types:
SBEC, SBEC 2, SBEC 3, SBEC 3+, SBEC 3A, SBEC 3A+, and SBEC 3B
NOTE:
During recovery, if the DRBIII® is not seeing the key off, you may need to remove power (B+) to
PCM by removing fuse(s) or disconnecting the PCM. When DRBIII® states to turn key ON,
reconnect fuse or harness connection.
Abort Recovery Specifics:
^ Follow instructions on the DRBIII® for the module type. See table above.
^ Some SBEC 3A, SBEC 3A+ AND SBEC 3B may be in a state where they can not correctly
identify a key cycle. In this case a Modified Key Cycle routine is required.
This state is present when the following message is displayed on the DRBIII(R): "Can not read Part
Number. Did not see Key On or PCM/TCM Controller may not be flashable". When this occurs
restart the flash session and when prompted to turn the ignition key to the LOCKED position, pull
the fuse(s) that supply battery power to the module instead. When prompted to turn the key to the
RUN position, replace the battery supply fuse(s) instead.
JTEC
Types:
^ JTEC, JTEC+
NOTE:
Viper ALL - Roll down windows especially Coupes before attempting a flash.
NOTE:
1999 WJ JTEC with Speed Proportional Steering module. Disconnect before and reconnect after
the PCM flash reprogramming session. Also see Transmission.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
NGC
Types:
^ NGC 1, NGC 2, and NGC 3
NOTE:
There are derivatives of NGC 3 that will be significant when reprogramming and or testing. NGC
modules use one of the longest time spans for flash reprogramming (approximately 15 minutes).
The NGCI and NGC3 controllers incorporate both an engine as well as a transmission controller in
a common package. The NGC2 controller incorporates the engine controller and an Electronic
Throttle Control (ETC) module in place of the TCM. All NGC controllers can be visually identified by
noting its four (4) wiring connectors. On manual transmission applications and the NGC2, only 3
connectors may be populated with pins.
NOTE:
On certain vehicles, the ABS CAB module connector MUST be disconnected prior to performing
this Repair Procedure. The CAB module and the PCM are connected at the same diagnostic
connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB module
connector, and reprogram the PCM per the Repair Procedure. When reprogramming is complete
turn the ignition switch to the OFF position, connect the CAB module connector, and then check for
DTC's. If the PCM becomes "locked" during reprogramming because the ABS CAB module
connector was not disconnected, then the PCM may be recovered by following the procedure in
this NOTE.

Control Fuse to pull when prompted by the DRBIII(R). Model Year 2001 and later have two Engine
Control Fuses (one 20 Amp and one 30 Amp) to pull when prompted by the DRBIII(R). The fuse(s)
are located in the PDC and need to be pulled/removed, when prompted, for at least 10 seconds.
SIEMENS
Types:
^ SIM-70
NOTE:
The SIM-70 is currently used on BUX PL and PG vehicles with a 1.6L ONLY. Abort Recovery

Follow DRBIII(R) prompts carefully.
BOSCH
Types:
^ EDC15V, EDC15-C5, and EDC16
NOTE:
While there have been other Bosch modules, the EDC15V is not flash reprogrammable.
Transmission controllers are usually flashed on the vehicle (since 1996).
Technicians may set the pinion factor on "NEW" modules either before or after flash
reprogramming. Suggestions follow.
After flash reprogramming and before returning the vehicle to the customer, always perform a
"QuickLearn" to the TCM.
EATX
Types:
^ EATX, EATX 2, EATX 3, EATX 3A, EATX 3B, EATX 4, and EATX 4A
NOTE:
Table shows which TCM was installed "as-built". Often TCMs are superseded by parts and or a
service bulletin.
Abort Recovery Specifics:
^ 1999 - 2000 WJ and 2000 AN/DN using 4.7L engines the service replacement EATX4A part
numbers 56041814AD and 56028227AH currently display a P/N read failed error after the flash is
completed during PIN verification. This DOES NOT mean the flash failed. Check for the part
number using DRBIII(R) in standalone mode. This exists only for the service replacement modules
listed above. Flash reprogramming for OE modules flash and read the part number correctly.
Follow DRBIII(R) prompts carefully.
NGC
Types:

^ NGC1, NGC2, NGC3
NOTE:
The NGC I1and NGC 3 have the EATX/XCORE and Engine modules combined. NGC 2 does not.
Vehicles with automatic transmissions using NGC2 will use an EATX4A.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
^ 2002 DR, 2002.5 DN, 2003 AN/DN and later with NGC have shown that in some instances the
CAB controller may need to be disconnected when attempting to flash the NGC controller. (This
should only be performed if an error occurs at the very beginning of the TCM flash portion.)
SIEMENS
Types:
^ EG552
NOTE:
EGS52 is used with the A580 automatic transmission WG Grand Cherokees with a 2.7L diesel
engine (BUX), ZH Crossfire and VA Sprinter.

JTEC
Types:
^ JTEC,JTEC+
NOTE:
Except for the 45RFE, 545RFE, and AW4 automatic transmissions, the JTEC controller also
provides transmission control functions on Dodge trucks and Jeep vehicles. Additionally, they are
used on some Cummins equipped Dodge trucks with manual and automatic transmissions.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
PRE 1996 EATX TRANSMISSION CONTROL MODULES
Prior to 1996 there was not a vehicle SCI communication wire going to the FWD EATX controller
only to the PCM. Those vehicle TCMs only communicate to the DRBIII(R) using CCD
communications.
For these FWD vehicles, use the CH5500 kit and CH7025 DIN cable when connecting those
modules to the DRBIII(R) vehicle connector.
For 1992-1993 vehicles, the TCM modules were upgraded to MY1995 software. Because of this
you will need to use the Yellow SuperCard2, CH8361,to set pinion factor or when using a "new"
(superseded) TCM from parts as only the SuperCard2 properly sets the pinion factor on these
updated modules.
Additionally, when flashing or installing P/Ns 4796121, 4796122, 4796123, or 4796124.
The wire from cavity 49 must be removed from the TCM connector, refer to service bulletin
18-24-95.

NOTE:
Refer to the table for specific applications.
DISCUSSION:
Mopar(R) is currently phasing out pre-programmed PCMs for the vehicles listed. New modules will
no longer be pre-programmed when received from Mopar(R). Replacement of future PCMs will
require programming utilizing the DRBIII(R) and TechCONNECT. The PCM will not operate the
engine until it is programmed. A Diagnostic Trouble Code (DTC) will be set - "not programmed".
CAUTION:
Extreme care must be taken when programming a calibration into a generic PCM. Do not randomly
select a calibration. Once a calibration is selected and programmed, the controller cannot be
reprogrammed to a different calibration. The module can only be reprogrammed to a more recent
version of that calibration.

PARTS REQUIRED:
SPECIAL TOOLS/EQUIPMENT REQUIRED:
NOTE:
An updated J1962 cable has been released. This cable has a red colored connector at the
DRBIII(R) connection. Use this cable whenever a flash is being performed.
REPAIR PROCEDURE:
NOTE:
When flashing a 2002 - 2004 LH vehicle the BCM may need to be disconnected if experiencing
failures during the flash of the transmission portion of the PCM. The BCM will need to be
disconnected after the module ID portion of the flash is complete. Before pressing Page Forward to
begin the flash of the PCM Turn the Key to the OFF position and disconnect the BCM. Then turn
the KEY to the RUN position and Press Page Forward to begin the PCM flash session.
NOTE:
If vehicle is a DAKOTA, then the ABS CAB module connector MUST be disconnected prior to
performing this Repair Procedure. The CAB module and the PCM are connected at the same
diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB
module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is
complete turn the ignition switch to the OFF position, connect the CAB module connector, and then
check for any erroneous DTC's. If the PCM becomes "locked" during reprogramming because the
ABS CAB module connector was not disconnected, then the PCM may be recovered by following
the procedure in this NOTE.
NOTE:
Whenever a controller is programmed, the software in the DRBIII(R); must be programmed with the
latest revision level available.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted and then follow the
directions on the DRBIII(R).
1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from
the DRBIII(R) memory. To clear the memory from the MAIN MENU power up the DRBIII(R) and
then:
a. Simultaneously press the "MORE" and "YES" keys.
b. A screen will appear requesting a "COLD BOOT".
c. Follow the on screen instructions by selecting the "F4" key.
d. When the DRB III(R) reboots to the MAIN MENU, proceed to Step 2.

DISCUSSION:
NOTE:
Many of the reasons a flash reprogramming procedure may not complete are documented in this
service bulletin, but if you are constantly having issues performing the flash reprogramming
procedure using a specific DRBIII(R), it is suggested you send the DRBIII(R) in question to
SPX/Miller Special Tools for service.
Occasionally a flash update procedure may not complete properly and/or the diagnostic equipment
may lock up or become disconnected during the procedure. Flash Reprogramming is a "CRITICAL
PROCESS"; an error may result in a no-start/failed control module. Most modules, encountering an
interruption or failure while reprogramming, are recoverable; a recoverable module is not covered
under the provisions of the warranty.
This service bulletin covers items that may cause this condition, a process to restart the flash
procedure, and miscellaneous information that will help prevent needless replacement of control
modules.
GENERAL: Flash Reprogramming is only authorized by a specific SERVICE BULLETIN, or
RECALL.
Review the entire Service Bulletin/Recall prior to performing a flash reprogramming update. Often
other parts may need to be serviced, replaced, or tested, prior to flash reprogramming, and ARE
REQUIRED as part of completing the Service Bulletin/Recall.
When flashing a Powertrain Control Module (PCM) or Transmission Control Module (TCM) there
are other legal requirements with labeling issues that are included in those service bulletins.
Other non-emission related modules, such as instrument clusters and Body Control Modules
(BCMs) do not require labels.
FLASH REPROGRAMMING SEQUENCE OF EVENTS
The process of flash reprogramming is similar to flashing the BIOS on a Personal Computer.
Interruptions, voltage problems, and a variety of other outside interactions can potentially interfere
with the process. This document seeks to provide information to minimize problems associated
with vehicle control module flash reprogramming. The description that follows is for most PCMs
and some TCMs. Other modules use different initiation procedures.
The process starts by selecting an update from the TechCONNECT Client or ISIS and then
"loading" that update into the DRBIII(R). Once the flash reprogramming update is loaded into the
DRBIII(R), and before the flash reprogramming begins, the DRBIII(R) verifies that the update
loaded from the TechCONNECT Client or ISIS is the proper update for the module. This is done
using part number supersedence. This verification occurs only if an update is required, available
(on the TechCONNECT Client or ISIS) and has been selected for programming.
^ The module is then placed into "Boot Strap" programming mode by the DRBIII(R). This module
mode gives the DRBIII(R) permission and the ability to proceed with the flash reprogramming
session.
^ Next, the current part number, which resides in the module's flash memory, is stored in a "Safe
Memory" location within the module. This memory location is not affected by flash memory erasure
and reprogramming, which are to follow.
^ Once the part number is safely stored, the flash memory in the control module is erased. From
this point forward any interruption in the flash process,
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3982
will result in a Non-Responsive module (NR). A NR module is a module that is either partially
erased or partially programmed.
^ After erasure, the actual reprogramming procedure starts, and the update software is
programmed into the flash memory within the module.
^ When reprogramming is completed, the flash memory is verified through an internal process in
the DRBIII(R) using a "Check Sum". This value is compared against another value that represents
what should be in memory and when matched, verifies successful reprogramming.
^ Next, a DRBIII(R) prompt is displayed instructing that the ignition switch be turned OFF. The
module exits the "Boot Strap" mode when the switch is turned off.
^ After a slight pause, the DRBIII(R) will prompt for the ignition switch to be turned ON. The
DRBIII(R) then reads the new part number in flash memory (along with a new computer program
the new part number is placed into the module's memory). If the new part number matches the
expected part number, the flash reprogramming session has completed successfully.
SOFTWARE VERSIONS MUST BE CURRENT
Before attempting a flash reprogramming session using the TechCONNECT Client, make sure you
have the most current DRBIII(R) software installed.
To verify whether your DRBIII(R) software is current, check the upper right-hand corner of the
TechCONNECT Client screen for DRBIII(R) Available Version, DRBIII(R) Current Version.
Often, because of multiple DRBIII(R)s in the shop, not all will get updated on a timely manner. The
installed DRBIII(R) software version can generally be found at the bottom center of most screens.
Alternately the version can be checked by pressing 6, 2, 5 from the DRBIII(R) Main Menu and
comparing it to what is available from a current TechCONNECT Client as described above.
If the TechCONNECT Client is current and the DRBIII(R) is not, it may be due to the fact that the
TechCONNECT Client does not force DRBIII(R) updates for "minor" revisions. Changes and new
support are added to the Vehicle Flash application on "minor" revisions on a regular basis. This is
why your TechCONNECT Client and DRBIII(R) must have the LATEST software revisions
installed.
DO NOT PASS on the option for updating to a "minor" revision!
Major updates require the DRBIII(R) to be updated prior to allowing any flash programming.
DRBIII(R) CABLES
A NEW DRBIII(R) cable was released as an Essential Service Tool! CH7000A - 8 ft.
Cable, DRBIII(R) to OBDII (J1962) DLC Connector.
CH7000A is the required cable for ALL flash reprogramming. The older CH7000 cable can be used
for diagnostics ONLY. One (1) cable was shipped to all dealerships. Easily identified, the correct
cable has a RED connector, which plugs into the DRBIII(R).
The cable modification enhances the DRBIII(R) communication capabilities when dealing with the
flash requirements of certain controllers/ECUs affected in part by the recent changes in DLC
connector configurations.
The new cable is required for ALL flash reprogramming sessions, and can be used wherever the
previous CH700017001 cables were used.
While not recommended for flash reprogramming usage, if you require a longer cable, there is also
a 12-foot cable released under pin CH7001A
The production of the previous CH700017001 cables has ceased. All orders placed will be
superseded to part number CH7000A/CH7001A.

NOTE:
Consider all cables wear items. Always inspect for worn, damaged cables, connectors that are
damaged or do not lock securely, and all mating connections including checking for corrosion on
the pins. REPLACE ALL suspect cables. Do not use worn or damaged cables when flash
reprogramming.
Failure to use the new cable or to use a damaged cable often results in failed flash reprogramming
sessions.
The 2 door Sebring, Stratus, and Avenger coupes (supplied by MMC) generally use the CH7O1O
cable (Pre-OBDII MMC vehicles will use the CH7005 cable).
TechCONNECT CABLE (GPIB)
Replace any suspect GPIB cable.
The GPIB cable provides the connection between TechCONNECT Client and the DRBIII(R).
This cable is used by the TechCONNECT Client for vehicle part number reads and to send update
files to the DRBIII(R).
Inspect this cable for loose connections, damaged connectors or terminals, and wear and tear. If
this cable becomes disconnected during a flash session, you may have to reload the update file
that you selected on the TechCONNECT Client.
TROUBLESHOOTING CONNECTIVITY OF THE DRBIII(R) UNIT TO THE TechCONNECT
APPLICATION.
1. Turn-on the power to the DRBIII(R) unit.
2. Select option 2 "Connect to TechCONNECT" and press Enter.
3. Attach the male mini D-shell amphenol GPIB connector of the new DRBIII(R) cable (part number
CH7035B) to the DRBIII(R) unit.
4. Insure that the larger female D-shell amphenol GPIB connector of the new DRBIII(R) cable is
properly attached to the male D-shell amphenol GPIB connector on the GPIB-USB-B protocol
converter, (part number CHGPIB-B).
5. Attach the USB cable from the GPIB-USB-B protocol converter to one of the USB ports on the
rear panel of the client CPU.
6. When the cable is attached to the USB port of the CPU for the first time, Windows 2000 will
detect the device and install software for it. Please wait for 25-30 seconds to complete the
installation.

ISIS NULL MODEM CABLE
Replace any suspect null modem cables.
International (ISIS), a PC-based CD program similar to TechCONNECT Client uses a null modem
cable for vehicle part number reads and to send update files to the DRBIII(R). Inspect this cable for
loose connections, damaged connectors or terminals, and wear and tear. If this cable becomes
disconnected during a flash download session, you will have to reload the update file or files.
GENERAL NOTES FOR CABLES AND VEHICLE CONNECTIONS
Consider ALL cables to be wear items.
Many successful dealers have dedicated cables devoted to "Flash ONLY".
Always have spare CH7000A, CH7010 and CH2002 GPIB or null modem cables available.
Inspect vehicle diagnostic connectors for potential problems that might cause communication
interruptions.
There are now clip repair kits available through teamPSE to replace the retaining clips for two of
these cables. To protect the DRBIII(R) from internal damage, the clips are designed to fail at above
25 lbs. of axial force. Kits are described in the table.
It is a good practice to discard cables that have damage to the pins, cuts, corrosion, or general
damage beyond the retaining clips.

These vehicles use MMC based modules. The CH8432 Supplemental Reprogramming Tool (SRT)
was shipped as a 2001 Essential Tool. The flash reprogramming update files will be downloaded
from TechCONNECT Client to the SRT for flash reprogramming sessions on these vehicles. Users
should closely follow the instructions that come with the tool. If the tool has not been initialized,
there is a known condition where it may take up to 5 or more attempts for it to fully initialize and
become functional.
NOTE:
Once it has successfully flashed, it is initialized and no further action is required.
PREPARING TO FLASH
It is highly recommended that a sign, or other process, be used that notifies other users that a
FLASH SESSION IS IN-PROGRESS and must NOT be interrupted. Interrupting some flash
reprogramming sessions at critical junctures can render a module inoperative. Another user may
not realize that a flash session is in-progress and may disturb or disconnect the DRBIII(R) or do
something on the vehicle that could interrupt the flash process.
Before starting the flash session, read, record and erase all DTCs found on the vehicle.
Also "Cold Boot" the DRBIII(R) and download the flash since this will erase the flash file from the
DRBIII(R) memory. (To "Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the
same time. Then press "F4").
Be sure to arrange the TechCONNECT and DRBIII(R) so that no cables are stretched across an
area where someone might trip over or kick a cable. When setting up your DRBIII(R), insure that it
rests on a surface where it will not fall or be bumped during reprogramming e.g.: DRBIII's have
been known to be swept off vehicle windshields by accident when a user bumps the wiper switch).
Check User settings on the DRBIII(R). From the DRBIII(R) Main menu, press 6,1 and check to
make sure item 1. Echo on PC is set to OFF. On occasion, when Echo on PC is set to ON, flash
reprogramming errors may occur.
VEHICLE BATTERY VOLTAGE
The flash programming procedure puts a load on the electrical system that may last from five to
twenty minutes depending on the particular flash reprogramming update. Connect a battery
charger to the vehicle. Set the charger to as close to 14 volts as possible. If the charger has a
timer, set it for 30 minutes BEFORE starting a flash reprogramming session. This will help to
prevent unwanted resets by either the DRBIII(R) and/or the vehicle module that are caused by
voltage fluctuations.
Alternately, as a bare minimum, use a "Battery Jump Box" when a battery charger is unavailable to
ensure adequate and stable system voltages on the module being flash reprogrammed.

Connected/Disconnected Flash Mode Using TechCONNECT
CONNECTED MODE FLASHING USING TechCONNECT
NOTE:
Capable but not recommended.
In this mode, the DRBIII(R) remains connected to the TechCONNECT Client and the vehicle
throughout the flash session. The DRBIII(R) is connected to the TechCONNECT Client using the
GPIB (CH7035) cable and to the vehicle using the vehicle I/O cable (the CH7000A for most
vehicles).
This mode is useful when the TechCONNECT Client is next to the vehicle being flashed.
Another advantage of this mode is that you are able to determine all available flash updates for the
vehicle you are connected to by clicking on the "Read Part Number(s) From Vehicle" button.
Again, it is important that other users do not attempt to reboot or move the TechCONNECT Client
while a flash update is in-progress.
The reprogramming procedure of this mode is initiated by selecting the controller option and
clicking "Download/Update" button on the TechCONNECT client.
DISCONNECTED FLASH MODE
NOTE:

Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3986
This is the preferred method.
This mode allows a user to flash a vehicle without being connected to the TechCONNECT Client.
This is a popular mode for flashing in a remote area of the service garage or in a back lot.
Before you attempt to use this mode, you must configure the DRBIII(R) for the desired update(s).
To do this, you must connect the DRBIII(R) to the TechCONNECT Client using the GPIB cable and
the CH7025 cable. It is not necessary to be connected to a vehicle. The GPIB (CH7035) cable will
be used to communicate with the TechCONNECT Client (for update file downloading) while the
CH7025 cable is used to provide power to the DRBIII(R).
After making the above connections, you are able to select one or more updates that you want to
perform. These selections are made by highlighting the desired updates and then clicking on the
"Download/Update" button by selecting the DRBIII(R) option on the TechCONNECT client.
Obviously, the DRBIII(R) does not have unlimited memory. If the file size of the selected updates
exceeds 948 KB, the "DRB Space Used" indicator (at the bottom-center of the TechCONNECT
Client screen) will change color from GREEN to RED. At this point you must de-select entries until
the indicator changes color to GREEN again.
When the updates have finished downloading, you may disconnect from the TechCONNECT Client
and take the DRBIII(R) to wherever the vehicle is located. The updates will remain in DRBIII(R)
memory for 8 hours while the DRBIII(R) is without power. If the DRBIII(R) is powered up for several
minutes before the 8 hour time period has expired, the update files will remain on the DRBIII(R) for
another 8 hours without power.
To start the actual flash process, after connecting to the vehicle in Disconnected Mode, you must
press "7 - Vehicle Flash" from the Main Menu on the DRBIII(R). Step by step instruction will follow
on the DRBIII(R) display. As with Connected Flash Mode, take the necessary precautions to insure
that others are aware of the flash session and that nothing disturbs the vehicle, DRBIII(R), or
cabling while performing the flash. Remember to use a battery charger set to 14 volts or a "battery
jump box".
Pay Attention While Performing Flash Reprogram Procedures
PAY ATTENTION WHILE PERFORMING FLASH REPROGRAMMING PROCEDURES
Before downloading the flash files, double check to see if the files that you have selected are the
appropriate ones for that vehicle. Don't forget about the "Read Part Numbers From Vehicle" option
on TechCONNECT Client, this can be of great assistance when trying to flash a module. If the files
selected don't download on the first attempt, try again.
The technician should NOT leave the vehicle when flash reprogramming a module.
Again, check to make sure that all cable connections are secure and that the DRBIII(R) rests on a
stable surface. If you are using a battery charger, insure that the settings and charging times are
correct and that the battery post clamps are securely fastened.
Read, record, and erase all DTCs found on the vehicle. Read and record the module type and part
number from the module that is to be flash reprogrammed.
Some control modules are not "abort-recovery" capable. When this is true, the scan tool will
indicate so by displaying a WARNING message prior to the start of reprogramming. For these
modules it is especially important that all precautions and procedures, outlined here, are carefully
followed.
Pay special attention to DRBIII(R) screen directions relating to key cycles. Missing a "Key ON" or
"Key OFF" can cause the module to have to be reflashed again. Due to the variety of module types
and vehicle options, you can't always anticipate key prompts, so be alert and ready to respond to
DRBIII(R) instructions.
Some screens will also instruct that certain modules, connectors or fuses be disconnected or pulled
prior to the start of reprogramming and re-installed immediately after completion. Be careful not to
anticipate the steps or order of operations for reprogramming any vehicle modules. Because of the
many possible changes that occur with each new release of scan tool software, always allow the
TSB/Recall and scan tool instructions to be your guide while performing flash reprogramming.
Flash reprogramming sessions usually range from 5 to 20 minutes. If the flash session has not
completed within 25 minutes after starting a flash reprogramming update, an error has most likely
occurred (Record the message that appears on the screen when a failure occurs). If this is the
case, or if you know that the flash process was interrupted, cycle the ignition key (OFF to the
locked position, then back ON). Reset the DRBIII(R) (power down for 4 seconds and then power
up) before attempting to restart the flash process. If the module still won't respond, turn the ignition
key off, disconnect the module from the vehicle for 2 minutes, reconnect the module, turn the
ignition key to run and try to restart the flash process again.
Regardless of what mode that you are in (Connected Flash or Disconnected Flash), if you have
tried twice (2 times) unsuccessfully to do a flash recovery and ALL DRBIII(R) instructions were
followed, perform the following:
^ Cold boot the DRBIII(R). This resets memory and removes all update files from the DRBIII(R).
(Push MORE and YES buttons at the same time, then press F4).
^ Reload the flash update file from the TechCONNECT Client.
^ If it fails to complete in the connected mode, first reboot the TechCONNECT Client before
re-attempting the flash download to the DRBIII(R).

Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3987
^ Proceed to reflash the module.
On vehicles that have multiple flash updates available, always complete and verify each flash
update before attempting the next one.
After all flash reprogramming is completed, read and erase all DTCs in all modules on the vehicle.
A variety of DTCs may be set, which are usually related to a loss of communication with the
module(s) being reprogrammed.
Verify the update by reading the new part number using the DRBIII(R). A good double check is to
read the part number using DRBIII(R) stand alone.
At times, other modules, wired in parallel, to the DLC connector have prevented flash
reprogramming sessions to be successful. After the failed attempt, review the appropriate wiring
diagram for the vehicle you are flash reprogramming and, with the key "OFF"; disconnect the other
modules and retry the flash. Complete the flash, turn the key "OFF" and reconnect any modules
that were disconnected. Refer to the "Programmable Modules" section later in this document for
more information.
Error Messages
ERROR MESSAGES
Block Echo/Compare Errors
Block Echo and Block Compare errors are often caused by voltage fluctuations, faulty I/O cables
(CH7OOOA, CH7005, CH7010) or faulty communication connections at the diagnostic connector.
Inspect for these conditions and review the sections on Vehicle Battery Voltage and Cable
recommendations.
Checksum Errors
Checksum Errors are generally caused by corrupt flash update files, which can be caused by
DRBIII(R) memory problems. If the DRBIII(R) has been without power for more than 8 hours, the
update files and system memory could be in a corrupted state. "Cold Boot" the DRBIII(R). (To
"Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the same time. Then press
"F4"). Reload the flash update file(s) from the TechCONNECT CLIENT. If it fails to complete in the
connected mode, first reboot the TechCONNECT Client before re-attempting the flash download to
the DRBIII(R). Then re-attempt the flash reprogramming process.
Enhanced and Original Abort Recovery
ENHANCED ABORT RECOVERY
Interruptions in the flash process are one of the main reasons for failed flash sessions and
non-responsive (NR) modules. Interrupting the flash process after the erase phase has started will
leave the control module in a non-functional state.
Generally, but not always, NR modules may be recovered successfully.
Briefly, abort recovery is the process used to get a NR module back to a fully functional state with
the latest software update. The technician should be familiar with the other sections in this
document and follow all DRBIII(R) user prompts carefully.
There are two methods for abort-recovery. The newer method is called "Enhanced Abort
Recovery". This is the preferred method since the original method takes several minutes longer
and requires the correct selection of module type from a list of possible PCM's or TCM's.
Starting with Release 60.1, a new useful feature was added to the flash reprogramming application
for Engine and Transmission control modules. The DRBIII(R) "writes" the YME and Controller Type
information to a "Safe Memory" location. This method allows for rapid recovery of the module part
number and minimizes errors that could otherwise be made by selecting the wrong controller type.
It also assumes that the user will attempt abort recovery for a failed flash attempt before moving to
another vehicle with the same DRBIII(R). If you need to move to another vehicle for flash
reprogramming you must erase the saved recovery information in order to successfully perform
flash reprogramming. Be careful to match the YME information displayed on the enhanced abort
recovery screen with the vehicle and module that you are attempting to recover. If you use the
recovery file on a different vehicle and module you could damage the module.
The recovery information will be displayed on your DRBIII(R), at the start of a flash session, only if
you previously encountered a problem that prevented a flash session from completing normally. If
your prior flash session was successful, the DRBIII(R) automatically erases the recovery file so that
the flash application will not show any recovery information at the start of your next flash session.
Enhanced abort recovery features:
^ Reduces the amount of time for the Module ID process.
^ Lowers the risk of possible user mistakes by presenting the user the Year, Model, Engine, and
Controller Type.
^ Currently only applicable to Engine and Transmission flash reprogramming.
^ The enhanced abort recovery file will only be erased upon a successful flash or manually by the
user.

Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3988
^ Cold booting (simultaneously pushing MORE & YES, then F4) the DRBIII(R) will not erase the
enhanced abort recovery file, but cold booting the DRBIII(R) will still erase the flash file so it can be
reloaded.
^ The user has a choice, at the start of a flash session, whether or not to use the enhanced abort
recovery feature. If the user chooses to erase the recovery file, then the DRBIII(R) will use the
original method of abort recovery.
^ Cycling the ignition key, when prompted by the DRBIII(R), is still necessary to put the controller
into bootstrap (reprogramming) mode.
ORIGINAL ABORT RECOVERY
If the choice is made to use the original method of abort recovery, a NR module is not always able
to provide the DRBIII with ID information. In this case the technician must enter this when prompted
by the DRBIII(R). Be patient when performing this process. If the module does not respond to
standard diagnostic requests, the DRBIII(R) may take several minutes before it determines that the
engine module is in a NR state. At this point, the DRBIII(R) displays the prompt "Could not
determine engine controller type. Please select from list" along with a list of possible controller
types (if the DRBIII(R) is attempting to identify a TCM, the prompt will say "trans" instead of
"engine" and list the possible trans controller types). Because of module variations, it is important
to correctly identify the PCM/TCM type so that the correct flash procedure is used. Failure to do
this will cause further problems and may damage the module. Tables are provided below to help
identify the proper module type to select. These tables correctly identify the modules that were on
the vehicles when they were built. However, some vehicles will have module types which were
superseded to a new type when a replacement part was installed (ie: EATX4 modules replaced
with an EATX4A). Correctly identify these modules using DRBIII(R) Standalone prior to attempting
flash reprogramming.
NOTE:
When instructed to turn the key to the LOCKED position, be sure that the key is not just turned to
the OFF position. The key must be rotated to the point at which it can be removed from the ignition
switch. On most vehicles the switch is on the steering column and at this position the steering
column is LOCKED. When instructed to turn the key to the RUN position, be careful not to turn the
key past this position which may engage the starter motor. This creates electrical noise which
interferes with the flash process.
General Steps for Abort Recovery
1. Review all Tips and Techniques before continuing. Pay special attention to the section on
Preparing to Flash a controller and to the Programmable Modules section.
2. Cycle the vehicle's ignition key to the LOCKED position and back to the RUN position.
3. Reset the DRBIII(R) by disconnecting the vehicle cable from the DRBIII(R) for 4 seconds and
then reconnecting the cable.
4. Depending on where the flash session was aborted, the DRBIII(R) may require that the
technician identify the control module type that was being flash reprogrammed. Use the PCM/TCM
configuration table below as a guide. This step is not necessary if using the enhanced abort
recovery method.
5. After selecting the proper control module type or choosing enhanced abort recovery, follow the
prompts that are displayed on the DRBIII(R).
NOTE:
If an error message is displayed at this point, an incorrect module type was most likely selected. If
this occurs, start the process over.
6. If the recovery process is unsuccessful, perform the following:
a. Review the TSB/Recall notice (authorizing the flash update) and all Tips and Techniques in this
document.
b. Reboot/Restart the TechCONNECT Client.
c. "Cold Boot" the DRBIII(R). (Press the MORE and YES buttons on the DRBIII(R) at the same
time, then press F4).
d. Start this process over from item # 1. If using Disconnected Mode, the flash update will have to
be reloaded from the TechCONNECT Client or ISIS DVD.

Programmable Modules
The following pages list the various modules that have flash reprogramming capability. It does not
mean that a flash is currently available. What will be described are the module types and
variations, followed by items to note, and finally, abort recovery specifics if applicable.
Powertrain Modules - Engine and Transmission
ENGINE - POWERTRAIN CONTROL MODULE (PCM)
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3993
There are a variety of Engine (PCM) modules that are flash reprogrammable. Suggestions that are
somewhat unique to each type will have comments. Prior to reprogramming a PCM, retrieve the
module information and module type using your DRBII I®. PCM information is used by many
modules. Be sure to check DIG's before and after performing all flash reprogramming event.
The DTC's associated with flash reprogramming generally relate to "lack of communication" with
the other modules during the reprogramming session.
SBEC
Types:
SBEC, SBEC 2, SBEC 3, SBEC 3+, SBEC 3A, SBEC 3A+, and SBEC 3B
NOTE:
During recovery, if the DRBIII® is not seeing the key off, you may need to remove power (B+) to
PCM by removing fuse(s) or disconnecting the PCM. When DRBIII® states to turn key ON,
reconnect fuse or harness connection.
Abort Recovery Specifics:
^ Follow instructions on the DRBIII® for the module type. See table above.
^ Some SBEC 3A, SBEC 3A+ AND SBEC 3B may be in a state where they can not correctly
identify a key cycle. In this case a Modified Key Cycle routine is required.
This state is present when the following message is displayed on the DRBIII(R): "Can not read Part
Number. Did not see Key On or PCM/TCM Controller may not be flashable". When this occurs
restart the flash session and when prompted to turn the ignition key to the LOCKED position, pull
the fuse(s) that supply battery power to the module instead. When prompted to turn the key to the
RUN position, replace the battery supply fuse(s) instead.
JTEC
Types:
^ JTEC, JTEC+
NOTE:
Viper ALL - Roll down windows especially Coupes before attempting a flash.
NOTE:
1999 WJ JTEC with Speed Proportional Steering module. Disconnect before and reconnect after
the PCM flash reprogramming session. Also see Transmission.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
NGC
Types:
^ NGC 1, NGC 2, and NGC 3
NOTE:
There are derivatives of NGC 3 that will be significant when reprogramming and or testing. NGC
modules use one of the longest time spans for flash reprogramming (approximately 15 minutes).
The NGCI and NGC3 controllers incorporate both an engine as well as a transmission controller in
a common package. The NGC2 controller incorporates the engine controller and an Electronic
Throttle Control (ETC) module in place of the TCM. All NGC controllers can be visually identified by
noting its four (4) wiring connectors. On manual transmission applications and the NGC2, only 3
connectors may be populated with pins.
NOTE:
On certain vehicles, the ABS CAB module connector MUST be disconnected prior to performing
this Repair Procedure. The CAB module and the PCM are connected at the same diagnostic
connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB module
connector, and reprogram the PCM per the Repair Procedure. When reprogramming is complete
turn the ignition switch to the OFF position, connect the CAB module connector, and then check for
DTC's. If the PCM becomes "locked" during reprogramming because the ABS CAB module
connector was not disconnected, then the PCM may be recovered by following the procedure in
this NOTE.

Control Fuse to pull when prompted by the DRBIII(R). Model Year 2001 and later have two Engine
Control Fuses (one 20 Amp and one 30 Amp) to pull when prompted by the DRBIII(R). The fuse(s)
are located in the PDC and need to be pulled/removed, when prompted, for at least 10 seconds.
SIEMENS
Types:
^ SIM-70
NOTE:
The SIM-70 is currently used on BUX PL and PG vehicles with a 1.6L ONLY. Abort Recovery

Follow DRBIII(R) prompts carefully.
BOSCH
Types:
^ EDC15V, EDC15-C5, and EDC16
NOTE:
While there have been other Bosch modules, the EDC15V is not flash reprogrammable.
Transmission controllers are usually flashed on the vehicle (since 1996).
Technicians may set the pinion factor on "NEW" modules either before or after flash
reprogramming. Suggestions follow.
After flash reprogramming and before returning the vehicle to the customer, always perform a
"QuickLearn" to the TCM.
EATX
Types:
^ EATX, EATX 2, EATX 3, EATX 3A, EATX 3B, EATX 4, and EATX 4A
NOTE:
Table shows which TCM was installed "as-built". Often TCMs are superseded by parts and or a
service bulletin.
Abort Recovery Specifics:
^ 1999 - 2000 WJ and 2000 AN/DN using 4.7L engines the service replacement EATX4A part
numbers 56041814AD and 56028227AH currently display a P/N read failed error after the flash is
completed during PIN verification. This DOES NOT mean the flash failed. Check for the part
number using DRBIII(R) in standalone mode. This exists only for the service replacement modules
listed above. Flash reprogramming for OE modules flash and read the part number correctly.
Follow DRBIII(R) prompts carefully.
NGC

^ NGC1, NGC2, NGC3
NOTE:
The NGC I1and NGC 3 have the EATX/XCORE and Engine modules combined. NGC 2 does not.
Vehicles with automatic transmissions using NGC2 will use an EATX4A.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
^ 2002 DR, 2002.5 DN, 2003 AN/DN and later with NGC have shown that in some instances the
CAB controller may need to be disconnected when attempting to flash the NGC controller. (This
should only be performed if an error occurs at the very beginning of the TCM flash portion.)
SIEMENS
Types:
^ EG552
NOTE:
EGS52 is used with the A580 automatic transmission WG Grand Cherokees with a 2.7L diesel
engine (BUX), ZH Crossfire and VA Sprinter.

JTEC
Types:
^ JTEC,JTEC+
NOTE:
Except for the 45RFE, 545RFE, and AW4 automatic transmissions, the JTEC controller also
provides transmission control functions on Dodge trucks and Jeep vehicles. Additionally, they are
used on some Cummins equipped Dodge trucks with manual and automatic transmissions.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
PRE 1996 EATX TRANSMISSION CONTROL MODULES
Prior to 1996 there was not a vehicle SCI communication wire going to the FWD EATX controller
only to the PCM. Those vehicle TCMs only communicate to the DRBIII(R) using CCD
communications.
For these FWD vehicles, use the CH5500 kit and CH7025 DIN cable when connecting those
modules to the DRBIII(R) vehicle connector.
For 1992-1993 vehicles, the TCM modules were upgraded to MY1995 software. Because of this
you will need to use the Yellow SuperCard2, CH8361,to set pinion factor or when using a "new"
(superseded) TCM from parts as only the SuperCard2 properly sets the pinion factor on these
updated modules.
Additionally, when flashing or installing P/Ns 4796121, 4796122, 4796123, or 4796124.
The wire from cavity 49 must be removed from the TCM connector, refer to service bulletin
18-24-95.

Overdrive Solenoid: Description and Operation
ASSEMBLY-TRANSMISSION SOLENOID/TRS
DESCRIPTION
The transmission solenoid/TRS assembly is internal to the transmission and mounted on the valve
body assembly. The assembly consists of six solenoids that control hydraulic pressure to the six
friction elements (transmission clutches), and the torque converter clutch. The pressure control
solenoid is located on the side of the solenoid/TRS assembly. The solenoid/TRS assembly also
contains five pressure switches that feed information to the TCM.
OPERATION SOLENOIDS
Solenoids are used to control the L/R, 2C, 4C, OD, and UD friction elements. The reverse clutch is
controlled by line pressure and the position of the manual valve in the valve body. All the solenoids
are contained within the Solenoid and Pressure Switch Assembly. The solenoid and pressure
switch assembly contains one additional solenoid, Multi-Select (MS), which serves primarily to
provide 2nd and 3rd gear limp-in operation.
The solenoids receive electrical power from the Transmission Control Relay through a single wire.
The TCM energizes or operates the solenoids individually by grounding the return wire of the
solenoid as necessary. When a solenoid is energized, the solenoid valve shifts, and a fluid
passage is opened or closed (vented or applied), depending on its default operating state. The
result is an apply or release of a frictional element.
The MS and UD solenoids are normally applied to allow transmission limp-in in the event of an
electrical failure.
The continuity of the solenoids and circuits are periodically tested. Each solenoid is turned on or off
depending on its current state. An inductive spike should be detected by the TCM during this test. If
no spike is detected, the circuit is tested again to verify the failure. In addition to the periodic
testing, the solenoid circuits are tested if a speed ratio or pressure switch error occurs.
PRESSURE SWITCHES
The TCM relies on five pressure switches to monitor fluid pressure in the L/R, 2C, 4C, UD, and OD
hydraulic circuits. The primary purpose of these switches is to help the TCM detect when clutch
circuit hydraulic failures occur. The switches close at 23 psi and open at 11 psi, and simply indicate
whether or not pressure exists. The switches are continuously monitored by the TCM for the
correct states (open or closed) in each gear as shown in the following charts 45RFE PRESSURE
SWITCH STATES and 545RFE PRESSURE SWITCH STATES:

Shift Solenoid: Description and Operation
ASSEMBLY-TRANSMISSION SOLENOID/TRS
DESCRIPTION
The transmission solenoid/TRS assembly is internal to the transmission and mounted on the valve
body assembly. The assembly consists of six solenoids that control hydraulic pressure to the six
friction elements (transmission clutches), and the torque converter clutch. The pressure control
solenoid is located on the side of the solenoid/TRS assembly. The solenoid/TRS assembly also
contains five pressure switches that feed information to the TCM.
OPERATION SOLENOIDS
Solenoids are used to control the L/R, 2C, 4C, OD, and UD friction elements. The reverse clutch is
controlled by line pressure and the position of the manual valve in the valve body. All the solenoids
are contained within the Solenoid and Pressure Switch Assembly. The solenoid and pressure
switch assembly contains one additional solenoid, Multi-Select (MS), which serves primarily to
provide 2nd and 3rd gear limp-in operation.
The solenoids receive electrical power from the Transmission Control Relay through a single wire.
The TCM energizes or operates the solenoids individually by grounding the return wire of the
solenoid as necessary. When a solenoid is energized, the solenoid valve shifts, and a fluid
passage is opened or closed (vented or applied), depending on its default operating state. The
result is an apply or release of a frictional element.
The MS and UD solenoids are normally applied to allow transmission limp-in in the event of an
electrical failure.
The continuity of the solenoids and circuits are periodically tested. Each solenoid is turned on or off
depending on its current state. An inductive spike should be detected by the TCM during this test. If
no spike is detected, the circuit is tested again to verify the failure. In addition to the periodic
testing, the solenoid circuits are tested if a speed ratio or pressure switch error occurs.
PRESSURE SWITCHES
The TCM relies on five pressure switches to monitor fluid pressure in the L/R, 2C, 4C, UD, and OD
hydraulic circuits. The primary purpose of these switches is to help the TCM detect when clutch
circuit hydraulic failures occur. The switches close at 23 psi and open at 11 psi, and simply indicate
whether or not pressure exists. The switches are continuously monitored by the TCM for the
correct states (open or closed) in each gear as shown in the following charts 45RFE PRESSURE
SWITCH STATES and 545RFE PRESSURE SWITCH STATES:

Control Module: Description and Operation
The Transmission Control Module (TCM) (2) may be sub-module within the Powertrain Control
Module (PCM) (3).
Or, for vehicles with a diesel engine, the Engine Control Module (ECM) (1). The PCM, and TCM
when equipped, is located at the right rear of the engine compartment, near the right inner fender.
The Transmission Control Module (TCM) controls all electronic operations of the transmission. The
TCM receives information regarding vehicle operation from both direct and indirect inputs, and
selects the operational mode of the transmission. Direct inputs are hard wired to, and used
specifically by the TCM. Indirect inputs are shared with the TCM via the vehicle communication
bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure

Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Control Module, A/T >
Component Information > Description and Operation > Page 4079
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request Some examples of TCM indirect outputs are:
- Transmission Temperature (to PCM)
- PRNDL Position (to cluster/CCN) In addition to monitoring inputs and controlling outputs, the TCM
has other important responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed.
BATTERY FEED
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain memory in the TCM. When the battery (B+) is disconnected, this memory is
lost. When the battery (B+) is restored, this memory loss is detected by the TCM and a Diagnostic
Trouble Code (DTC) is set.
CLUTCH VOLUME INDEXES (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur.
Gear ratios can be determined by using the Scan Tool and reading the Input/Output Speed Sensor
values in the "Monitors" display Gear ratio can be obtained by dividing the Input Speed Sensor
value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Control Module, A/T >
Component Information > Description and Operation > Page 4080
In direct drive (3rd gear), the gear ratio changes to 1:1. The gear ratio changes as clutches are
applied and released. By monitoring the length of time it takes for the gear ratio to change following
a shift request, the TCM can determine the volume of fluid used to apply or release a friction
element.
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Certain mechanical problems within the input clutch assembly can cause inadequate or
out-of-range element volumes. Also, defective Input/Output Speed Sensors and wiring can cause
these conditions. The following chart identifies the appropriate clutch volumes and when they are
monitored/updated:
SHIFT SCHEDULES
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following:
- Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

Component Information > Description and Operation > Page 4081
As driving conditions change, the TCM appropriately adjusts the shift schedule. Refer to the chart
to determine the appropriate operation expected, depending on driving conditions.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

Fluid - A/T: Testing and Inspection
FLUID
DIAGNOSIS AND TESTING EFFECTS OF INCORRECT FLUID LEVEL
A low fluid level allows the pump to take in air along with the fluid. Air in the fluid will cause fluid
pressures to be low and develop slower than normal. If the transmission is overfilled, the gears
churn the fluid into foam. This aerates the fluid and causing the same conditions occurring with a
low level. In either case, air bubbles cause fluid overheating, oxidation, and varnish buildup which
interferes with valve and clutch operation. Foaming also causes fluid expansion which can result in
fluid overflow from the transmission vent or fill tube. Fluid overflow can easily be mistaken for a
leak if inspection is not careful.
CAUSES OF BURNT FLUID
Burnt, discolored fluid is a result of overheating which has three primary causes. 1. Internal clutch
slippage, usually caused by low line pressure, inadequate clutch apply pressure, or clutch seal
failure. 2. A result of restricted fluid flow through the main and/or auxiliary cooler. This condition is
usually the result of a faulty or improperly installed
drainback valve, a damaged oil cooler, or severe restrictions in the coolers and lines caused by
debris or kinked lines.
3. Heavy duty operation with a vehicle not properly equipped for this type of operation. Trailer
towing or similar high load operation will overheat
the transmission fluid if the vehicle is improperly equipped. Such vehicles should have an auxiliary
transmission fluid cooler, a heavy duty cooling system, and the engine/axle ratio combination
needed to handle heavy loads.
FLUID CONTAMINATION
Transmission fluid contamination is generally a result of: ^
adding incorrect fluid
^ failure to clean dipstick and fill tube when checking level
^ engine coolant entering the fluid . internal failure that generates debris
^ overheat that generates sludge (fluid breakdown)
^ failure to replace contaminated converter after repair
The use of non-recommended fluids can result in transmission failure. The usual results are erratic
shifts, slippage, abnormal wear and eventual failure due to fluid breakdown and sludge formation.
Avoid this condition by using recommended fluids only.
The dipstick cap and fill tube should be wiped clean before checking fluid level. Dirt, grease and
other foreign material on the cap and tube could fall into the tube if not removed beforehand. Take
the time to wipe the cap and tube clean before withdrawing the dipstick.
Engine coolant in the transmission fluid is generally caused by a cooler malfunction. The only
remedy is to replace the radiator as the cooler in the radiator is not a serviceable part. If coolant
has circulated through the transmission, an overhaul is necessary.
The torque converter should also be replaced whenever a failure generates sludge and debris. This
is necessary because normal converter flushing procedures will not remove all contaminants.

Information > Service and Repair > Fluid Level Check
Fluid - A/T: Service and Repair Fluid Level Check
FLUID LEVEL CHECK
Low fluid level can cause a variety of conditions because it allows the pump to take in air along with
the fluid. As in any hydraulic system, air bubbles make the fluid spongy, therefore, pressures will be
low and build up slowly.
Improper filling can also raise the fluid level too high. When the transmission has too much fluid,
the geartrain churns up foam and cause the same conditions which occur with a low fluid level.
In either case, air bubbles can cause overheating and/or fluid oxidation, and varnishing. This can
interfere with normal valve, clutch, and accumulator operation. Foaming can also result in fluid
escaping from the transmission vent where it may be mistaken for a leak.
After the fluid has been checked, seat the dipstick fully to seal out water and dirt.
The transmission has a dipstick to check oil level. It is located on the right side of the engine. Be
sure to wipe all dirt from dipstick handle before removing.
The torque converter fills in both the P (PARK) and N (NEUTRAL) positions. Place the selector
lever in P (PARK) to be sure that the fluid level check is accurate. The engine should be running at
idle speed for at least one minute, with the vehicle on level ground. At normal operating
temperature (approximately 82°C. or 180°F), the fluid level is correct if it is in the HOT region
(cross-hatched area) on the oil level indicator. The fluid level will be approximately at the upper
COLD hole of the dipstick at 70°F fluid temperature.
NOTE: Engine and Transmission should be at normal operating temperature before performing this
procedure.
1. Start engine and apply parking brake. 2. Shift the transmission into DRIVE for approximately 2
seconds. 3. Shift the transmission into REVERSE for approximately 2 seconds. 4. Shift the
transmission into PARK. 5. Hook up scan tool and select transmission. 6. Select sensors. 7. Read
the transmission temperature value. 8. Compare the fluid temperature value with the chart. 9.
Adjust transmission fluid level shown on the dipstick according to the Transmission Fluid
Temperature Chart.
NOTE: After adding any fluid to the transmission, wait a minimum of 2 minutes for the oil to fully
drain from the fill tube into the transmission before rechecking the fluid level.

FLUID AND FILTER REPLACEMENT
For proper service intervals Refer to LUBRICATION & MAINTENANCE.
REMOVAL
1. Hoist and support vehicle on safety stands. 2. Place a large diameter shallow drain pan beneath
the transmission pan. 3. Remove bolts holding front and sides of pan to transmission. 4. Loosen
bolts holding rear of pan to transmission. 5. Slowly separate front of pan away from transmission
allowing the fluid to drain into drain pan. 6. Hold up pan and remove remaining bolts holding pan to
transmission. 7. While holding pan level, lower pan away from transmission. 8. Pour remaining fluid
in pan into drain pan.
9. Remove the screw holding the primary oil filter (1) to valve body.
10. Separate filter from valve body and oil pump and pour fluid in filter into drain pan. 11. Inspect
the oil filter seal in the bottom of the oil pump. If the seal is not installed completely in the oil pump,
or is otherwise damaged, then remove
and discard the oil filter seal from the bottom of the oil pump. If the seal is installed correctly and is
in good condition, it can be reused.
12. If replacing the cooler return filter (2), use Oil Filter Wrench 8321 to remove the filter from the
transmission. 13. Dispose of used trans fluid and filter(s) properly.
INSPECTION
Inspect bottom of pan and magnet for excessive amounts of metal. A light coating of clutch material
on the bottom of the pan does not indicate a problem unless accompanied by a slipping condition
or shift lag. If fluid and pan are contaminated with excessive amounts of debris, refer to the
diagnosis.
CLEANING
1. Using a suitable solvent, clean pan and magnet. 2. Using a suitable gasket scraper, clean
original sealing material from surface of transmission case and the transmission pan.
INSTALLATION
CAUTION: The primary oil filter seal MUST be fully installed flush against the oil pump body. DO
NOT install the seal onto the filter neck and attempt to install the filter and seal as an assembly.
Damage to the transmission will result.
1. If necessary, install a new primary oil filter seal in the oil pump inlet bore. Seat the seal in the
bore with a suitable tool (appropriately sized drift or
socket, the butt end of a hammer, or other suitable tool).
2. Place replacement filter in position on valve body and into the oil pump. 3. Install screw to hold
the primary oil filter (1) to valve body. Tighten screw to 4.5 Nm (40 inch lbs.) torque. 4. Install new
cooler return filter (2) onto the transmission, if necessary. Torque the filter to 14.12 Nm (125 inch
lbs.). 5. Place bead of Mopar(R) RTV sealant onto the transmission case sealing surface. 6. Place
pan in position on transmission. 7. Install bolts to hold pan to transmission. Tighten bolts to 11.8
Nm (105 inch lbs.) torque. 8. Lower vehicle and fill transmission with Mopar(R) ATF +4.

SUBJECT: RFE Transmission Filters - Delayed Engagement And Related Transmission DTC'S
OVERVIEW: This bulletin involves verifying the build date of the transmission, and if necessary, the
replacement of both the cooler return and sump filters in the transmission.
MODELS:
2005 - 2006 (DR) Ram Truck
2005 - 2006 (HB) Durango
2005 - 2006 (KJ) Liberty / Cherokee
2005 - 2006 (ND) Dakota
2005 - 2006 (WK / WH) Grand Cherokee
2006 (XK) Commander
NOTE:
This bulletin applies to vehicles equipped with the a 45RFE or a 545RFE automatic transmission
(sales code DG4 or DGQ respectively) having a specific transmission build date code (see the
below DIAGNOSIS section for further details).
SYMPTOM/CONDITION:
The customer may experience an initial delayed shift engagement following an extended off (not
running) period of time, generally after being parked overnight. The initial shift engagement may
feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine
start.
The customer may also experience a MIL illumination. Investigation may determine that the MIL is
due to one or more of the following Diagnostic Trouble Codes (DIG's):
P0868 - Line Pressure Low. This DIG will be the most frequently occurring DTC for the delayed
shift condition.
P0944 - Loss Of Hydraulic Pump Prime.
P0731 - Gear Ratio Error In 1st.
P0736 - Gear Ratio Error In Reverse.
P0841 - LR Pressure Switch Rationality.
P0876 - UD Pressure Switch Rationality.
The delayed engagement and MIL condition (DTC's) may be caused by a suspect transmission
cooler return filter with a part number of 04799662AB. A suspect 04799662AB cooler return filter
may cause the transmission sump filter to split at its plastic-to-metal crimp. If the transmission
sump filter becomes split at the crimp, then one or more of the above DTC's may also occur.
DIAGNOSIS:
1. Turn the ignition to the "OFF" position.
2. Raise the vehicle on a suitable lift.

A/T - Delayed Shift Engagement/Related DTC's Set > Page 4116
3. Inspect for the transmission build date (Julian date) (Fig. 1). The transmission build date can be
determined by inspection of the 20 digit transmission identification number
(DDDYxxxxxPpartnumber). The transmission identification number is stamped on the left side
(driver side) of the transmission oil pan flange. The first four (4) digits of the transmission
identification number are the transmission build date, in Julian date format. An example of a
transmission identification number would be 101510492P52119684AA. The first three digits ( 101 )
of the identification number equal the day of the year, in this case 101 equals April 11. The fourth
digit ( 5 ) of the identification number equals the calendar year, in this case 5 equals 2005. So 1015
equals April 11, 2005.
4. Determine if the vehicle's transmission was built on or between one of the two sets of Julian date
build ranges listed below:
a. Julian date 0425 (February 11, 2005) to Julian date 0455 (February 15, 2005). 0425 to 0455.
b. Julian date 1015 (April 11, 2005) to Julian date 2345 (August 22, 2005). 1015 to 2345.
5. If the vehicle has the above condition, and if the transmission Julian build date is on or between
the range of dates listed above, perform the Repair Procedure.
NOTE:
Both the transmission cooler return filter and the transmission sump filter MUST BE replaced at the
same time.
PARTS REQUIRED:
NOTE:
DO NOT use a replacement cooler return filter with a part number of 04799662AB. This filter is
suspect of causing the above condition. The cooler

return filter part number is stenciled on the side of the filter's metal case.
SPECIAL TOOLS/EQUIPMENT REQUIRED:
REPAIR PROCEDURE:
NOTE:
All cooler return filters with the "AB" suffix (04799662AB) are suspect. The above condition may be
corrected by replacing a suspect "AB" filter with a new cooler return filter whose part number is
04799662 (with no suffix or with a suffix that is other than the "AB" level), and a new sump filter.
NOTE:
BOTH the sump oil filter and the cooler return filter MUST BE replaced in the transmission at the
same time. Do not replace one filter without also replacing the other filter.
NOTE:
A replacement 04799662 cooler return filter may come packaged with a separate threaded adapter
stud. The threaded adapter stud is used to attach the cooler return filter to the transmission.
Inspect the stud and note end without threads. Install the stud end without the threads into the
cooler return filter and tighten the stud-to4ilter connection to 18.6 Nm (165 in.lbs.). Once the
threaded adapter stud has been installed to the cooler return filter, install the assembled cooler
return filter to the transmission and tighten the filter to 14.1 Nm (125 in.lbs.)
Use the procedures outlined in TechCONNECT(R) (Service Information Tab / 21 - Transmission
Transaxle / Automatic - 45RFE 545RFE / Fluid / Standard Procedure / Fluid and Filter
Replacement) to replace BOTH the transmission cooler return filter and the transmission sump oil
filter.
NOTE:
Always install the sump filter seal to the bottom of the transmission oil pump first, then install the
sump filter to the oil pump and previously installed seal. DO NOT install the sump filter seal to the
sump filter and then attempt to install both to the oil pump.
POLICY: Reimbursable within the provisions of the warranty.

DISCUSSION:
The customer may experience an initial delayed shift engagement following an extended off (not
running) period of time, generally after being parked overnight. The initial shift engagement may
feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine
start.
The customer may not have experienced the delayed shift engagement until after the transmission
has been serviced, where the cooler return filter was replaced during the service and/or repair.
The condition is not detrimental to the transmission but may cause concern with the customer.
The above condition may be caused by a suspect cooler return filter a part number of
04799662AB. This "AB" suffix / level filter may allow transmission fluid to drain back out of the
torque converter. The drain back condition may occur over a period time when the engine (and
transmission) are not running. With less fluid in the torque converter a delay in gear engagement
may occur at engine start up while the torque converter fills to its proper fluid level.
All 04799662AB cooler return filters with the "AB" suffix are suspect. The above condition may be
corrected by replacing a suspect "AB" filter with a new cooler return filter whose part number is
04799662 (with no suffix or with a suffix that is other than the "AB" level).
NOTE:
The cooler return filter, p/n 04799662, will not be available until September 09, 2005. The filter part
number is stenciled on the side of the filter case.

identification number are the transmission build date, in Julian date format. An example of a
transmission identification number would be 101510492P52119684AA. The first three digits ( 101 )
of the identification number equal the day of the year, in this case 101 equals April 11. The fourth
digit ( 5 ) of the identification number equals the calendar year, in this case 5 equals 2005. So 1015
equals April 11, 2005.
4. Determine if the vehicle's transmission was built on or between one of the two sets of Julian date
build ranges listed below:
a. Julian date 0425 (February 11, 2005) to Julian date 0455 (February 15, 2005). 0425 to 0455.
b. Julian date 1015 (April 11, 2005) to Julian date 2345 (August 22, 2005). 1015 to 2345.
5. If the vehicle has the above condition, and if the transmission Julian build date is on or between
the range of dates listed above, perform the Repair Procedure.

SUBJECT: 45RFE / 545RFE Trans - Delayed Engagement Due To Cooler Return Filter
Replacement
OVERVIEW: This bulletin involves a transmission delayed shift condition that may occur following
the replacement of the internal cooler return filter.
MODELS:
2000 - 2004 (AN) Dakota
2000 - 2003 (DN) Durango
2003 - 2006 (DR) Ram Truck
2004 - 2006 (HB) Durango
2002 - 2006 (KJ) Liberty

2006 (XK) Commander
NOTE:
This bulletin applies to vehicles equipped with a 45RFE or a 545RFE automatic transmission (sales
code DG4 or DGQ respectively).
DISCUSSION:
The customer may experience an initial delayed shift engagement following an extended off (not
running) period of time, generally after being parked overnight. The initial shift engagement may
feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine
start.
The customer may not have experienced the delayed shift engagement until after the transmission
has been serviced, where the cooler return filter was replaced during the service and/or repair.
The condition is not detrimental to the transmission but may cause concern with the customer.
The above condition may be caused by a suspect cooler return filter a part number of
04799662AB. This "AB" suffix / level filter may allow transmission fluid to drain back out of the
torque converter. The drain back condition may occur over a period time when the engine (and
transmission) are not running. With less fluid in the torque converter a delay in gear engagement
may occur at engine start up while the torque converter fills to its proper fluid level.
All 04799662AB cooler return filters with the "AB" suffix are suspect. The above condition may be
corrected by replacing a suspect "AB" filter with a new cooler return filter whose part number is
04799662 (with no suffix or with a suffix that is other than the "AB" level).
NOTE:
The cooler return filter, p/n 04799662, will not be available until September 09, 2005. The filter part
number is stenciled on the side of the filter case.

Fluid Pressure Sensor/Switch: Description and Operation
SENSOR-LINE PRESSURE
DESCRIPTION
The TCM utilizes a closed-loop system to control transmission line pressure. The system contains
a variable force style solenoid, the Pressure Control Solenoid, mounted on the side of the solenoid
and pressure switch assembly. The solenoid is duty cycle controlled by the TCM to vent the
unnecessary line pressure supplied by the oil pump back to the sump. The system also contains a
variable pressure style sensor, the Line Pressure Sensor, which is a direct input to the TCM. The
line pressure solenoid monitors the transmission line pressure and completes the feedback loop to
the TCM. The TCM uses this information to adjust its control of the pressure control solenoid to
achieve the desired line pressure.
OPERATION
The TCM calculates the desired line pressure based upon inputs from the transmission and engine.
The TCM calculates the torque input to the transmission and uses that information as the primary
input to the calculation. The line pressure is set to a predetermined value during shifts and when
the transmission is in the PARK and NEUTRAL positions. This is done to ensure consistent shift
quality. During all other operation, the actual line pressure is compared to the desired line pressure
and adjustments are made to the pressure control solenoid duty cycle.

Overdrive Indicator Lamp: Description and Operation
A tow/haul indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional overdrive automatic transmission, this indicator is electronically
disabled. The tow/haul indicator consists of the text "TOW/HAUL", which appears in the lower
portion of the odometer/trip odometer indicator Vacuum Fluorescent Display (VFD) unit.
The odometer/trip odometer VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial
face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "TOW/ HAUL" appears in an amber color and at the
same lighting level as the odometer/trip odometer information when it is illuminated by the
instrument cluster electronic circuit board. The tow/haul indicator is serviced as a unit with the VFD
in the instrument cluster.
The tow/haul indicator gives an indication to the vehicle operator when the Off position of the
tow/haul switch has been selected, disabling the electronically controlled overdrive feature of the
automatic transmission. This indicator is controlled by the instrument cluster circuit board based
upon cluster programming and electronic messages received by the cluster from the Powertrain
Control Module (PCM) over the Programmable Communications Interface (PCI) data bus.
The tow/haul indicator is completely controlled by the instrument cluster logic circuit, and that logic
will only allow this indicator to operate when the instrument cluster receives a battery current input
on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
tow/haul indicator for the following reasons:
- Tow/Haul Lamp-On Message - Each time the cluster receives a tow/haul lamp-on message from
the PCM indicating that the Off position of the tow/haul switch has been selected, the tow/haul
indicator will be illuminated. The indicator remains illuminated until the cluster receives a tow/haul
lamp-off message from the PCM, or until the ignition switch is turned to the Off position, whichever
occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the tow/haul indicator will be
turned on, then off again during the VFD portion of the test to confirm the functionality of the VFD
and the cluster control circuitry.
The PCM continually monitors the tow/haul switch to determine the proper outputs to the automatic
transmission. The PCM then sends the proper tow/haul lamp-on and lamp-off messages to the
instrument cluster.
For proper diagnosis of the overdrive control system, the PCM, the PCI data bus, or the electronic
message inputs to the instrument cluster that control the tow/haul indicator, a diagnostic scan tool
is required.

Shift Indicator: Description and Operation
An electronic automatic transmission gear selector indicator is standard factory-installed equipment
on this model. However, on vehicles not equipped with an optional automatic transmission, this
indicator is electronically disabled. The gear selector indicator information is displayed in an
electronic, blue-green Vacuum-Fluorescent Display (VFD) unit. The VFD unit is soldered onto the
cluster electronic circuit board and is visible through a window with a smoked clear lens located on
the lower edge of the speedometer gauge dial face of the cluster overlay. The dark lens over the
VFD prevents the indicator from being clearly visible when it is not illuminated.
The gear selector indicator VFD displays the following characters from left to right: "P," "R," "N,"
"D," "2," and "1". Respectively, these characters represent the park, reverse, neutral, drive, second
gear, and first gear positions of the transmission gear selector lever on the steering column. The
VFD illuminates a rectangular box around the character that represents the currently selected lever
position.
During daylight hours (exterior lamps Off) the gear selector VFD is illuminated at full brightness for
clear visibility. At night (exterior lamps are On), the VFD lighting level is adjusted with the other
cluster illumination lamps using the panel lamps dimmer thumbwheel on the headlamp switch.
However, a "Parade" mode position of the panel lamps dimmer thumbwheel allows the VFD to be
illuminated at full brightness if the exterior lamps are turned On during daylight hours. The gear
selector indicator VFD is serviced as a unit with the instrument cluster.
The electronic gear selector indicator gives an indication to the vehicle operator of the transmission
gear that has been selected with the automatic transmission gear selector lever. This indicator is
controlled by the instrument cluster circuit board based upon cluster programming. The cluster
circuitry automatically configures itself for the proper transmission and automatic transmission
model based upon the hard wired transmission range sensor mux circuit input to the cluster.
The gear selector indicator information is displayed by a dedicated Vacuum Fluorescent Display
(VFD) unit soldered onto the instrument cluster electronic circuit board, and the VFD will not display
the gear selector indicator information after the ignition switch is turned to the Off position. Each
time the cluster is disconnected from battery current for more than about five minutes, it must
configure itself for the automatic transmission model that is in the vehicle once it is reconnected to
battery current. The instrument cluster circuitry configures the gear selector indicator VFD based
upon the following inputs from the transmission range sensor:
- Open Circuit - If the cluster is configured for an automatic transmission and the transmission
range sensor mux circuit is open, the cluster circuitry controls the gear selector indicator display
based upon electronic messages received from the electronic Transmission Control Module ( TCM)
over the Programmable Communications Interface (PCI) data bus. If the transmission range sensor
mux circuit is open and no electronic messages are received from the TCM within two seconds, the
instrument cluster circuitry will not display any gear selector position until the condition is resolved
or until the ignition switch is turned to the Off position, whichever occurs first.
- Resolved Circuit - If the transmission range sensor mux circuit is resolved, the cluster circuitry
controls the gear selector indicator display based upon the resistance value of the hard wired input
from the transmission range sensor. If the cluster is configured for an automatic transmission with a
transmission range sensor input and detects a short to ground or an open in the transmission
range sensor mux input, the instrument cluster circuitry will not display any gear selector position in
the VFD. The VFD display for the short-to-ground and open circuit conditions will continue until the
condition is resolved or until the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gear selector indicator
VFD will display all of its characters at once during the VFD portion of the test to confirm the
functionality of the VFD and the cluster control circuitry.
On models with a TCM, the TCM continually monitors the transmission range sensor, then sends
the proper gear selector indicator position messages to the instrument cluster. On models without a
TCM, the instrument cluster continually monitors the hard wired transmission range sensor
multiplexed input.
On models with a TCM, for proper diagnosis of the transmission range sensor, the TCM, the PCI
data bus, or the electronic message inputs to the instrument cluster that control the gear selector
indicator, a diagnostic scan tool is required.

Temperature Warning Indicator - A/T: Description and Operation
A transmission over-temperature indicator is standard equipment on all instrument clusters.
However, on vehicles not equipped with an optional automatic transmission, this indicator is
electronically disabled. This indicator is located on the left side of the instrument cluster, to the left
of the fuel gauge.
The transmission over-temperature indicator consists of a stencil-like cutout of the text "TRANS
TEMP" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. A red Light Emitting
Diode (LED) behind the cutout in the opaque layer of the overlay causes the "TRANS TEMP" text
to appear in red through the translucent outer layer of the overlay when the indicator is illuminated
from behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The
transmission over-temperature indicator is serviced as a unit with the instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
transmission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus.
The transmission over-temperature indicator Light Emitting Diode (LED) is completely controlled by
the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the
instrument cluster receives a battery current input on the fused ignition switch output (run-start)
circuit. Therefore, the LED will always be off when the ignition switch is in any position except On
or Start. The LED only illuminates when it is provided a path to ground by the instrument cluster
transistor. The instrument cluster will turn on the transmission over-temperature indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-On Message - Each time the cluster receives a trans over-temp lamp-on
message from the PCM indicating that the transmission fluid temperature is 135° C (275° F) or
higher, the indicator will be illuminated and a single chime tone is sounded. The indicator remains
illuminated until the cluster receives a trans over-temp lamp-off message from the PCM, or until the
ignition switch is turned to the Off position, whichever occurs first. The chime tone feature will only
repeat during the same ignition cycle if the transmission over-temperature indicator is cycled off
and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the transmission
over-temperature indicator will be turned on, then off again during the bulb check portion of the test
to confirm the functionality of the LED and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition. The PCM then sends the proper trans over-temp lamp-on or lamp-off
messages to the instrument cluster. If the instrument cluster turns on the transmission
over-temperature indicator due to a high transmission oil temperature condition, it may indicate that
the transmission and/or the transmission cooling system are being overloaded or that they require
service. For further diagnosis of the transmission over-temperature indicator or the instrument
cluster circuitry that controls the LED.
For proper diagnosis of the transmission temperature sensor, the PCM, the PCI data bus, or the
electronic message inputs to the instrument cluster that control the transmission over-temperature
indicator, a diagnostic scan tool is required.

Overdrive Solenoid: Description and Operation
ASSEMBLY-TRANSMISSION SOLENOID/TRS
DESCRIPTION
The transmission solenoid/TRS assembly is internal to the transmission and mounted on the valve
body assembly. The assembly consists of six solenoids that control hydraulic pressure to the six
friction elements (transmission clutches), and the torque converter clutch. The pressure control
solenoid is located on the side of the solenoid/TRS assembly. The solenoid/TRS assembly also
contains five pressure switches that feed information to the TCM.
OPERATION SOLENOIDS
Solenoids are used to control the L/R, 2C, 4C, OD, and UD friction elements. The reverse clutch is
controlled by line pressure and the position of the manual valve in the valve body. All the solenoids
are contained within the Solenoid and Pressure Switch Assembly. The solenoid and pressure
switch assembly contains one additional solenoid, Multi-Select (MS), which serves primarily to
provide 2nd and 3rd gear limp-in operation.
The solenoids receive electrical power from the Transmission Control Relay through a single wire.
The TCM energizes or operates the solenoids individually by grounding the return wire of the
solenoid as necessary. When a solenoid is energized, the solenoid valve shifts, and a fluid
passage is opened or closed (vented or applied), depending on its default operating state. The
result is an apply or release of a frictional element.
The MS and UD solenoids are normally applied to allow transmission limp-in in the event of an
electrical failure.
The continuity of the solenoids and circuits are periodically tested. Each solenoid is turned on or off
depending on its current state. An inductive spike should be detected by the TCM during this test. If
no spike is detected, the circuit is tested again to verify the failure. In addition to the periodic
testing, the solenoid circuits are tested if a speed ratio or pressure switch error occurs.
PRESSURE SWITCHES
The TCM relies on five pressure switches to monitor fluid pressure in the L/R, 2C, 4C, UD, and OD
hydraulic circuits. The primary purpose of these switches is to help the TCM detect when clutch
circuit hydraulic failures occur. The switches close at 23 psi and open at 11 psi, and simply indicate
whether or not pressure exists. The switches are continuously monitored by the TCM for the
correct states (open or closed) in each gear as shown in the following charts 45RFE PRESSURE
SWITCH STATES and 545RFE PRESSURE SWITCH STATES:

> Component Information > Description and Operation
Overdrive Indicator Lamp: Description and Operation
A tow/haul indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional overdrive automatic transmission, this indicator is electronically
disabled. The tow/haul indicator consists of the text "TOW/HAUL", which appears in the lower
portion of the odometer/trip odometer indicator Vacuum Fluorescent Display (VFD) unit.
The odometer/trip odometer VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial
face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "TOW/ HAUL" appears in an amber color and at the
same lighting level as the odometer/trip odometer information when it is illuminated by the
instrument cluster electronic circuit board. The tow/haul indicator is serviced as a unit with the VFD
in the instrument cluster.
The tow/haul indicator gives an indication to the vehicle operator when the Off position of the
tow/haul switch has been selected, disabling the electronically controlled overdrive feature of the
automatic transmission. This indicator is controlled by the instrument cluster circuit board based
upon cluster programming and electronic messages received by the cluster from the Powertrain
Control Module (PCM) over the Programmable Communications Interface (PCI) data bus.
The tow/haul indicator is completely controlled by the instrument cluster logic circuit, and that logic
will only allow this indicator to operate when the instrument cluster receives a battery current input
on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
tow/haul indicator for the following reasons:
- Tow/Haul Lamp-On Message - Each time the cluster receives a tow/haul lamp-on message from
the PCM indicating that the Off position of the tow/haul switch has been selected, the tow/haul
indicator will be illuminated. The indicator remains illuminated until the cluster receives a tow/haul
lamp-off message from the PCM, or until the ignition switch is turned to the Off position, whichever
occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the tow/haul indicator will be
turned on, then off again during the VFD portion of the test to confirm the functionality of the VFD
and the cluster control circuitry.
The PCM continually monitors the tow/haul switch to determine the proper outputs to the automatic
transmission. The PCM then sends the proper tow/haul lamp-on and lamp-off messages to the
instrument cluster.
For proper diagnosis of the overdrive control system, the PCM, the PCI data bus, or the electronic
message inputs to the instrument cluster that control the tow/haul indicator, a diagnostic scan tool
is required.

Overdrive Switch: Description and Operation
SWITCH-TOW/HAUL OVERDRIVE
DESCRIPTION
The tow/haul overdrive OFF (control) switch is located in the shift lever arm. The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the tow/haul overdrive
OFF mode to be entered and the Tow/Haul lamp to be illuminated. Pressing the switch a second
time causes normal overdrive operation to be restored and the tow/haul lamp to be turned off. The
tow/haul overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the tow/haul overdrive switch is turned to the OFF position, or when illuminated by the
transmission control module.

Control Module: Description and Operation
The Transmission Control Module (TCM) (2) may be sub-module within the Powertrain Control
Module (PCM) (3).
Or, for vehicles with a diesel engine, the Engine Control Module (ECM) (1). The PCM, and TCM
when equipped, is located at the right rear of the engine compartment, near the right inner fender.
The Transmission Control Module (TCM) controls all electronic operations of the transmission. The
TCM receives information regarding vehicle operation from both direct and indirect inputs, and
selects the operational mode of the transmission. Direct inputs are hard wired to, and used
specifically by the TCM. Indirect inputs are shared with the TCM via the vehicle communication
bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure

Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Relays and Modules - A/T
> Control Module, A/T > Component Information > Description and Operation > Page 4193
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request Some examples of TCM indirect outputs are:
- Transmission Temperature (to PCM)
- PRNDL Position (to cluster/CCN) In addition to monitoring inputs and controlling outputs, the TCM
has other important responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed.
BATTERY FEED
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain memory in the TCM. When the battery (B+) is disconnected, this memory is
lost. When the battery (B+) is restored, this memory loss is detected by the TCM and a Diagnostic
Trouble Code (DTC) is set.
CLUTCH VOLUME INDEXES (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur.
Gear ratios can be determined by using the Scan Tool and reading the Input/Output Speed Sensor
values in the "Monitors" display Gear ratio can be obtained by dividing the Input Speed Sensor
value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Relays and Modules - A/T
> Control Module, A/T > Component Information > Description and Operation > Page 4194
In direct drive (3rd gear), the gear ratio changes to 1:1. The gear ratio changes as clutches are
applied and released. By monitoring the length of time it takes for the gear ratio to change following
a shift request, the TCM can determine the volume of fluid used to apply or release a friction
element.
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Certain mechanical problems within the input clutch assembly can cause inadequate or
out-of-range element volumes. Also, defective Input/Output Speed Sensors and wiring can cause
these conditions. The following chart identifies the appropriate clutch volumes and when they are
monitored/updated:
SHIFT SCHEDULES
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following:
- Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Relays and Modules - A/T
> Control Module, A/T > Component Information > Description and Operation > Page 4195
As driving conditions change, the TCM appropriately adjusts the shift schedule. Refer to the chart
to determine the appropriate operation expected, depending on driving conditions.

These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Transmission Control System Relay: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

RELAY-TRANSMISSION CONTROL 45RFE/545RFE
DESCRIPTION
NOTE: The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power
to the solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off", no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Fluid Pressure Sensor/Switch: Description and Operation
SENSOR-LINE PRESSURE
DESCRIPTION
The TCM utilizes a closed-loop system to control transmission line pressure. The system contains
a variable force style solenoid, the Pressure Control Solenoid, mounted on the side of the solenoid
and pressure switch assembly. The solenoid is duty cycle controlled by the TCM to vent the
unnecessary line pressure supplied by the oil pump back to the sump. The system also contains a
variable pressure style sensor, the Line Pressure Sensor, which is a direct input to the TCM. The
line pressure solenoid monitors the transmission line pressure and completes the feedback loop to
the TCM. The TCM uses this information to adjust its control of the pressure control solenoid to
achieve the desired line pressure.
OPERATION
The TCM calculates the desired line pressure based upon inputs from the transmission and engine.
The TCM calculates the torque input to the transmission and uses that information as the primary
input to the calculation. The line pressure is set to a predetermined value during shifts and when
the transmission is in the PARK and NEUTRAL positions. This is done to ensure consistent shift
quality. During all other operation, the actual line pressure is compared to the desired line pressure
and adjustments are made to the pressure control solenoid duty cycle.

Overdrive Switch: Description and Operation
SWITCH-TOW/HAUL OVERDRIVE
DESCRIPTION
The tow/haul overdrive OFF (control) switch is located in the shift lever arm. The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the tow/haul overdrive
OFF mode to be entered and the Tow/Haul lamp to be illuminated. Pressing the switch a second
time causes normal overdrive operation to be restored and the tow/haul lamp to be turned off. The
tow/haul overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the tow/haul overdrive switch is turned to the OFF position, or when illuminated by the
transmission control module.

SENSOR-TRANSMISSION RANGE
DESCRIPTION
The Transmission Range Sensor (TRS) is part of the solenoid module, which is mounted to the top
of the valve body inside the transmission. The Transmission Range Sensor (TRS) has five switch
contact pins that: ^
Determine shift lever position
^ Supply ground to the Starter Relay in Park and Neutral only.
^ Supply +12 V to the backup lamps in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

SENSOR-INPUT SPEED
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following: ^
Transmission gear ratio
^ Speed ratio error detection
^ CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following: . Torque converter clutch slippage . Torque converter element speed ratio.

Transmission Temperature Sensor/Switch: Description and Operation
SENSOR-TRANSMISSION TEMPERATURE
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: ^
Battery (ambient) temperature
^ Engine coolant temperature
^ In-gear run time since start-up

Shift Solenoid: Description and Operation
ASSEMBLY-TRANSMISSION SOLENOID/TRS
DESCRIPTION
The transmission solenoid/TRS assembly is internal to the transmission and mounted on the valve
body assembly. The assembly consists of six solenoids that control hydraulic pressure to the six
friction elements (transmission clutches), and the torque converter clutch. The pressure control
solenoid is located on the side of the solenoid/TRS assembly. The solenoid/TRS assembly also
contains five pressure switches that feed information to the TCM.
OPERATION SOLENOIDS
Solenoids are used to control the L/R, 2C, 4C, OD, and UD friction elements. The reverse clutch is
controlled by line pressure and the position of the manual valve in the valve body. All the solenoids
are contained within the Solenoid and Pressure Switch Assembly. The solenoid and pressure
switch assembly contains one additional solenoid, Multi-Select (MS), which serves primarily to
provide 2nd and 3rd gear limp-in operation.
The solenoids receive electrical power from the Transmission Control Relay through a single wire.
The TCM energizes or operates the solenoids individually by grounding the return wire of the
solenoid as necessary. When a solenoid is energized, the solenoid valve shifts, and a fluid
passage is opened or closed (vented or applied), depending on its default operating state. The
result is an apply or release of a frictional element.
The MS and UD solenoids are normally applied to allow transmission limp-in in the event of an
electrical failure.
The continuity of the solenoids and circuits are periodically tested. Each solenoid is turned on or off
depending on its current state. An inductive spike should be detected by the TCM during this test. If
no spike is detected, the circuit is tested again to verify the failure. In addition to the periodic
testing, the solenoid circuits are tested if a speed ratio or pressure switch error occurs.
PRESSURE SWITCHES
The TCM relies on five pressure switches to monitor fluid pressure in the L/R, 2C, 4C, UD, and OD
hydraulic circuits. The primary purpose of these switches is to help the TCM detect when clutch
circuit hydraulic failures occur. The switches close at 23 psi and open at 11 psi, and simply indicate
whether or not pressure exists. The switches are continuously monitored by the TCM for the
correct states (open or closed) in each gear as shown in the following charts 45RFE PRESSURE
SWITCH STATES and 545RFE PRESSURE SWITCH STATES:
45RFE PRESSURE SWITCH STATES

Indicator - A/T > Component Information > Description and Operation
Temperature Warning Indicator - A/T: Description and Operation
A transmission over-temperature indicator is standard equipment on all instrument clusters.
However, on vehicles not equipped with an optional automatic transmission, this indicator is
electronically disabled. This indicator is located on the left side of the instrument cluster, to the left
of the fuel gauge.
The transmission over-temperature indicator consists of a stencil-like cutout of the text "TRANS
TEMP" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. A red Light Emitting
Diode (LED) behind the cutout in the opaque layer of the overlay causes the "TRANS TEMP" text
to appear in red through the translucent outer layer of the overlay when the indicator is illuminated
from behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The
transmission over-temperature indicator is serviced as a unit with the instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
transmission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus.
The transmission over-temperature indicator Light Emitting Diode (LED) is completely controlled by
the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the
instrument cluster receives a battery current input on the fused ignition switch output (run-start)
circuit. Therefore, the LED will always be off when the ignition switch is in any position except On
or Start. The LED only illuminates when it is provided a path to ground by the instrument cluster
transistor. The instrument cluster will turn on the transmission over-temperature indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-On Message - Each time the cluster receives a trans over-temp lamp-on
message from the PCM indicating that the transmission fluid temperature is 135° C (275° F) or
higher, the indicator will be illuminated and a single chime tone is sounded. The indicator remains
illuminated until the cluster receives a trans over-temp lamp-off message from the PCM, or until the
ignition switch is turned to the Off position, whichever occurs first. The chime tone feature will only
repeat during the same ignition cycle if the transmission over-temperature indicator is cycled off
and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the transmission
over-temperature indicator will be turned on, then off again during the bulb check portion of the test
to confirm the functionality of the LED and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition. The PCM then sends the proper trans over-temp lamp-on or lamp-off
messages to the instrument cluster. If the instrument cluster turns on the transmission
over-temperature indicator due to a high transmission oil temperature condition, it may indicate that
the transmission and/or the transmission cooling system are being overloaded or that they require
service. For further diagnosis of the transmission over-temperature indicator or the instrument
cluster circuitry that controls the LED.
For proper diagnosis of the transmission temperature sensor, the PCM, the PCI data bus, or the
electronic message inputs to the instrument cluster that control the transmission over-temperature
indicator, a diagnostic scan tool is required.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

System Relay, A/T > Component Information > Diagrams > Diagram Information and Instructions > Page 4298
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

RELAY-TRANSMISSION CONTROL 45RFE/545RFE
DESCRIPTION
NOTE: The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power
to the solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off", no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Indicator - A/T > Component Information > Description and Operation
Transmission Mode Indicator - A/T: Description and Operation
An electronic automatic transmission gear selector indicator is standard factory-installed equipment
on this model. However, on vehicles not equipped with an optional automatic transmission, this
indicator is electronically disabled. The gear selector indicator information is displayed in an
electronic, blue-green Vacuum-Fluorescent Display (VFD) unit. The VFD unit is soldered onto the
cluster electronic circuit board and is visible through a window with a smoked clear lens located on
the lower edge of the speedometer gauge dial face of the cluster overlay. The dark lens over the
VFD prevents the indicator from being clearly visible when it is not illuminated.
The gear selector indicator VFD displays the following characters from left to right: "P," "R," "N,"
"D," "2," and "1". Respectively, these characters represent the park, reverse, neutral, drive, second
gear, and first gear positions of the transmission gear selector lever on the steering column. The
VFD illuminates a rectangular box around the character that represents the currently selected lever
position.
During daylight hours (exterior lamps Off) the gear selector VFD is illuminated at full brightness for
clear visibility. At night (exterior lamps are On), the VFD lighting level is adjusted with the other
cluster illumination lamps using the panel lamps dimmer thumbwheel on the headlamp switch.
However, a "Parade" mode position of the panel lamps dimmer thumbwheel allows the VFD to be
illuminated at full brightness if the exterior lamps are turned On during daylight hours. The gear
selector indicator VFD is serviced as a unit with the instrument cluster.
The electronic gear selector indicator gives an indication to the vehicle operator of the transmission
gear that has been selected with the automatic transmission gear selector lever. This indicator is
controlled by the instrument cluster circuit board based upon cluster programming. The cluster
circuitry automatically configures itself for the proper transmission and automatic transmission
model based upon the hard wired transmission range sensor mux circuit input to the cluster.
The gear selector indicator information is displayed by a dedicated Vacuum Fluorescent Display
(VFD) unit soldered onto the instrument cluster electronic circuit board, and the VFD will not display
the gear selector indicator information after the ignition switch is turned to the Off position. Each
time the cluster is disconnected from battery current for more than about five minutes, it must
configure itself for the automatic transmission model that is in the vehicle once it is reconnected to
battery current. The instrument cluster circuitry configures the gear selector indicator VFD based
upon the following inputs from the transmission range sensor:
- Open Circuit - If the cluster is configured for an automatic transmission and the transmission
range sensor mux circuit is open, the cluster circuitry controls the gear selector indicator display
based upon electronic messages received from the electronic Transmission Control Module ( TCM)
over the Programmable Communications Interface (PCI) data bus. If the transmission range sensor
mux circuit is open and no electronic messages are received from the TCM within two seconds, the
instrument cluster circuitry will not display any gear selector position until the condition is resolved
or until the ignition switch is turned to the Off position, whichever occurs first.
- Resolved Circuit - If the transmission range sensor mux circuit is resolved, the cluster circuitry
controls the gear selector indicator display based upon the resistance value of the hard wired input
from the transmission range sensor. If the cluster is configured for an automatic transmission with a
transmission range sensor input and detects a short to ground or an open in the transmission
range sensor mux input, the instrument cluster circuitry will not display any gear selector position in
the VFD. The VFD display for the short-to-ground and open circuit conditions will continue until the
condition is resolved or until the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gear selector indicator
VFD will display all of its characters at once during the VFD portion of the test to confirm the
functionality of the VFD and the cluster control circuitry.
On models with a TCM, the TCM continually monitors the transmission range sensor, then sends
the proper gear selector indicator position messages to the instrument cluster. On models without a
TCM, the instrument cluster continually monitors the hard wired transmission range sensor
multiplexed input.
On models with a TCM, for proper diagnosis of the transmission range sensor, the TCM, the PCI
data bus, or the electronic message inputs to the instrument cluster that control the gear selector
indicator, a diagnostic scan tool is required.

SENSOR-TRANSMISSION RANGE
DESCRIPTION
The Transmission Range Sensor (TRS) is part of the solenoid module, which is mounted to the top
of the valve body inside the transmission. The Transmission Range Sensor (TRS) has five switch
contact pins that: ^
Determine shift lever position
^ Supply ground to the Starter Relay in Park and Neutral only.
^ Supply +12 V to the backup lamps in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

SENSOR-INPUT SPEED
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following: ^
Transmission gear ratio
^ Speed ratio error detection
^ CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following: . Torque converter clutch slippage . Torque converter element speed ratio.

SENSOR-TRANSMISSION TEMPERATURE
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: ^
Battery (ambient) temperature
^ Engine coolant temperature
^ In-gear run time since start-up

SOLENOID SWITCH VALVE
The Solenoid Switch Valve (SSV) controls the direction of the transmission fluid when the L/R-TCC
solenoid is energized.
The Solenoid Switch Valve controls line pressure from the LR-TCC solenoid. In 1st gear, the SSV
will be in the downshifted position, thus directing fluid to the L/R clutch circuit. In 2nd, 3rd, 4th, and
fifth gears, the solenoid switch valve will be in the upshifted position and directs the fluid into the
torque converter clutch (TCC) circuit.
When shifting into 1st gear, a special hydraulic sequence is performed to ensure SSV movement
into the downshifted position. The L/R pressure switch is monitored to confirm SSV movement. If
the movement is not confirmed (the L/R pressure switch does not close), 2nd gear is substituted for
1st. A DTC will be set after three unsuccessful attempts are made to get into 1st gear in one given
key start.
MANUAL VALVE
The manual valve is a relay valve. The purpose of the manual valve is to direct fluid to the correct
circuit needed for a specific gear or driving range. The manual valve, as the name implies, is
manually operated by the driver with a lever located on the top of the valve body. The valve is
connected mechanically by a cable to the gearshift mechanism. The valve is held in each of its
positions by a roller detent spring (2) that engages the "roostercomb" of the TRS selector plate (1).
LOW/REVERSE SWITCH VALVE
The low/reverse switch valve allows the low/reverse clutch to be operated by either the LR/CC
solenoid or the MS solenoid.

Valve Body: Service and Repair Cleaning
CLEANING
Clean the valve housings, valves, plugs, springs, and separator plates with a standard parts
cleaning solution only. Do not use gasoline, kerosene, or any type of caustic solution.
Do not immerse any of the electrical components in cleaning solution. Clean the electrical
components by wiping them off with dry shop towels only.
Dry all except the electrical parts with compressed air. Make sure all passages are clean and free
from obstructions. Do not use rags or shop towels to dry or wipe off valve body components. Lint
from these materials can stick to valve body parts, interfere with valve operation, and clog filters
and fluid passages.

Valve Body: Service and Repair Inspection
INSPECTION
Inspect all of the valve body mating surfaces for scratches, nicks, burrs, or distortion. Use a
straightedge to check surface flatness. Minor scratches may be removed with crocus cloth using
only very light pressure.
Minor distortion of a valve body mating surface may be corrected by smoothing the surface with a
sheet of crocus cloth. Position the crocus cloth on a surface plate, sheet of plate glass or equally
flat surface. If distortion is severe or any surfaces are heavily scored, the valve body will have to be
replaced.
Inspect the valves and plugs for scratches, burrs, nicks, or scores. Minor surface scratches on steel
valves and plugs can be removed with crocus cloth but do not round off the edges of the valve or
plug lands. Maintaining sharpness of these edges is vitally important. The edges prevent foreign
matter from lodging between the valves and plugs and the bore.
Inspect all the valve and plug bores in the valve body. Use a penlight to view the bore interiors.
Replace the valve body if any bores are distorted or scored. Inspect all of the valve body springs.
The springs must be free of distortion, warpage or broken coils.
Trial fit each valve and plug in its bore to check freedom of operation. When clean and dry, the
valves and nines should drop freely into the bores
Valve body bores do not change dimensionally with use. If the valve body functioned correctly
when new, it will continue to operate properly after cleaning and inspection. It should not be
necessary to replace a valve body assembly unless it is damaged in handling.
Inspect all the accumulator bores in the valve body. Use a penlight to view the bore interiors.
Replace the valve body if any bores are distorted or scored. Inspect all of the accumulator springs.
The springs must be free of distortion, warpage or broken coils.

Inspect all the fluid seals on the valve body. Replace any seals that are cracked, distorted, or
damaged in any way. These seals pass fluid pressure directly to the clutches. Any pressure leak at
these points, may cause transmission performance problems.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

DISCUSSION:
The axle fill holes on some Dodge Truck vehicle axles may be located considerably higher than the
actual fluid level. Filling the axle until the fluid comes out of the fill hole will over fill the axle, which
may cause fluid foaming. When checking fluid level or filling a rear axle with fluid, you must
measure the distance from the bottom of the fill hole to the top of the actual fluid level. This can
easily be accomplished using a pipe cleaner or piece of wire. Make a 90 degree bend in the wire 2
inches from the end. The wire can then be inserted into the axle fill hole to use as a dipstick.
Measure the distance from the bend to the oil level. The fluid levels for the axles are shown in the
table below.

ADJUSTMENTS
Launch shudder is a vibration that occurs at first acceleration from a stop. Shudder vibration
usually peaks at the engines highest torque output. Shudder is a symptom associated with vehicles
using a two-piece propeller shaft. To decrease shudder, lower the center bearing in 1/8 inch
increments. Use shim stock or fabricated plates. Plate stock must be used to maintain compression
of the rubber insulator around the bearing. Do not use washers. Replace the original bolts with the
appropriate increased length bolts.

Drive/Propeller Shaft: Testing and Inspection
PROPELLER SHAFT VIBRATION
Out-of-round tires or wheels that are out of balance, will cause a low frequency vibration. Driveline
vibration can also caused by loose or damaged engine mounts.
Propeller shaft vibration increases with vehicle speed. A vibration that occurs at a specific speed
range, is not usually caused by an out of balance propeller shaft. Defective universal joints or an
incorrect propeller shaft angle are usually the cause of such a vibration.
DRIVELINE VIBRATION
PROPELLER SHAFT BALANCE
If propeller shaft is suspected of being out of balance, use the following procedure.
NOTE: Indexing propeller shaft 180° relative to the yoke may eliminate some vibrations.
1. Raise and support vehicle. 2. Clean all foreign material from the propeller shaft and universal
joints. 3. Inspect propeller shaft for missing balance weights, broken welds and bent areas. If
propeller shaft is bent, it must be replaced. 4. Inspect universal joints for wear and properly
installed. 5. Check propeller shaft bolt torques. 6. Remove wheels and install lug nuts to retain
brake rotors. 7. Mark and number the shaft six inches from the pinion yoke end at four positions
90° apart. 8. Run and accelerate vehicle until vibration occurs. Note the intensity and speed the
vibration occurred. Stop the engine.

Shaft > Component Information > Specifications > Page 4542
9. Install a screw clamp at position (1).
10. Start engine and check vibration. If there is little or no change move the clamp to the next
positions. Repeat the vibration test.
NOTE: If there is no difference in vibration at this positions, the vibration may not be the propeller
shaft.
11. If vibration decreased, install a second clamp (1) and repeat the test.
12. If additional clamp causes an additional vibration, separate the clamps 1/2 inch (1) above and
below the mark. Repeat the vibration test. 13. Increase distance between the clamp screws (1) (2)
and repeat test, until the least amount of vibration is noticed. Bend the slack end of the clamps
so screws will not loosen.
14. If vibration remains unacceptable, repeat the procedure to the front end of the propeller shaft.
15. Install wheels and lower vehicle.

PROPELLER SHAFT RUNOUT
1. Clean propeller shaft surface, where dial indicator will contact the shaft. 2. Install dial indicator
perpendicular to the shaft surface. 3. Measure runout at the center and ends of the shaft away from
weld areas, so weld process does not affect measurements. 4. Refer to Runout Specifications
chart. 5. If runout is out of specification, index the shaft 180° and take shaft runout measurements
again. 6. If runout is now within specifications, mark shaft and yokes for proper orientation. 7. If
runout is not within specifications, verify runout of the transmission/transfer case and axle are
within specifications. Correct as necessary and
measure propeller shaft runout again.
8. Replace propeller shaft if the runout still exceeds the limits.

Flywheel: Testing and Inspection
FLYWHEEL
Check flywheel runout whenever misalignment is suspected. Flywheel runout should not exceed
0.08 mm (0.003 inch). Measure runout at the outer edge of the flywheel face with a dial indicator.
Mount the indicator on a stud installed in place of one of the flywheel bolts.
Common causes of runout are: ^
heat warpage
^ improper machining
^ incorrect bolt tightening
^ improper seating on crankshaft flange shoulder
^ foreign material on crankshaft flange
Flywheel machining is not recommended. The flywheel clutch surface is machined to a unique
contour and machining will negate this feature. Minor flywheel scoring can be cleaned up by hand
with 180 grit emery or with surface grinding equipment. Remove only enough material to reduce
scoring ( approximately 0.001 - 0.003 inch). Heavy stock removal is not recommended. Replace
the flywheel if scoring is severe and deeper than 0.076 mm (0.003 inch). Excessive stock removal
can result in flywheel cracking or warpage after installation; it can also weaken the flywheel and
interfere with proper clutch release.
Clean the crankshaft flange before mounting the flywheel. Dirt and grease on the flange surface
may cock the flywheel causing excessive runout. Use new bolts when remounting a flywheel and
secure the bolts with Mopar Lock And Seal or equivalent. Tighten flywheel bolts to specified torque
only. Overtightening can distort the flywheel hub causing runout.

Overdrive Indicator Lamp: Description and Operation
A tow/haul indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional overdrive automatic transmission, this indicator is electronically
disabled. The tow/haul indicator consists of the text "TOW/HAUL", which appears in the lower
portion of the odometer/trip odometer indicator Vacuum Fluorescent Display (VFD) unit.
The odometer/trip odometer VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial
face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "TOW/ HAUL" appears in an amber color and at the
same lighting level as the odometer/trip odometer information when it is illuminated by the
instrument cluster electronic circuit board. The tow/haul indicator is serviced as a unit with the VFD
in the instrument cluster.
The tow/haul indicator gives an indication to the vehicle operator when the Off position of the
tow/haul switch has been selected, disabling the electronically controlled overdrive feature of the
automatic transmission. This indicator is controlled by the instrument cluster circuit board based
upon cluster programming and electronic messages received by the cluster from the Powertrain
Control Module (PCM) over the Programmable Communications Interface (PCI) data bus.
The tow/haul indicator is completely controlled by the instrument cluster logic circuit, and that logic
will only allow this indicator to operate when the instrument cluster receives a battery current input
on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
tow/haul indicator for the following reasons:
- Tow/Haul Lamp-On Message - Each time the cluster receives a tow/haul lamp-on message from
the PCM indicating that the Off position of the tow/haul switch has been selected, the tow/haul
indicator will be illuminated. The indicator remains illuminated until the cluster receives a tow/haul
lamp-off message from the PCM, or until the ignition switch is turned to the Off position, whichever
occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the tow/haul indicator will be
turned on, then off again during the VFD portion of the test to confirm the functionality of the VFD
and the cluster control circuitry.
The PCM continually monitors the tow/haul switch to determine the proper outputs to the automatic
transmission. The PCM then sends the proper tow/haul lamp-on and lamp-off messages to the
instrument cluster.
For proper diagnosis of the overdrive control system, the PCM, the PCI data bus, or the electronic
message inputs to the instrument cluster that control the tow/haul indicator, a diagnostic scan tool
is required.

Shift Indicator: Description and Operation
An electronic automatic transmission gear selector indicator is standard factory-installed equipment
on this model. However, on vehicles not equipped with an optional automatic transmission, this
indicator is electronically disabled. The gear selector indicator information is displayed in an
electronic, blue-green Vacuum-Fluorescent Display (VFD) unit. The VFD unit is soldered onto the
cluster electronic circuit board and is visible through a window with a smoked clear lens located on
the lower edge of the speedometer gauge dial face of the cluster overlay. The dark lens over the
VFD prevents the indicator from being clearly visible when it is not illuminated.
The gear selector indicator VFD displays the following characters from left to right: "P," "R," "N,"
"D," "2," and "1". Respectively, these characters represent the park, reverse, neutral, drive, second
gear, and first gear positions of the transmission gear selector lever on the steering column. The
VFD illuminates a rectangular box around the character that represents the currently selected lever
position.
During daylight hours (exterior lamps Off) the gear selector VFD is illuminated at full brightness for
clear visibility. At night (exterior lamps are On), the VFD lighting level is adjusted with the other
cluster illumination lamps using the panel lamps dimmer thumbwheel on the headlamp switch.
However, a "Parade" mode position of the panel lamps dimmer thumbwheel allows the VFD to be
illuminated at full brightness if the exterior lamps are turned On during daylight hours. The gear
selector indicator VFD is serviced as a unit with the instrument cluster.
The electronic gear selector indicator gives an indication to the vehicle operator of the transmission
gear that has been selected with the automatic transmission gear selector lever. This indicator is
controlled by the instrument cluster circuit board based upon cluster programming. The cluster
circuitry automatically configures itself for the proper transmission and automatic transmission
model based upon the hard wired transmission range sensor mux circuit input to the cluster.
The gear selector indicator information is displayed by a dedicated Vacuum Fluorescent Display
(VFD) unit soldered onto the instrument cluster electronic circuit board, and the VFD will not display
the gear selector indicator information after the ignition switch is turned to the Off position. Each
time the cluster is disconnected from battery current for more than about five minutes, it must
configure itself for the automatic transmission model that is in the vehicle once it is reconnected to
battery current. The instrument cluster circuitry configures the gear selector indicator VFD based
upon the following inputs from the transmission range sensor:
- Open Circuit - If the cluster is configured for an automatic transmission and the transmission
range sensor mux circuit is open, the cluster circuitry controls the gear selector indicator display
based upon electronic messages received from the electronic Transmission Control Module ( TCM)
over the Programmable Communications Interface (PCI) data bus. If the transmission range sensor
mux circuit is open and no electronic messages are received from the TCM within two seconds, the
instrument cluster circuitry will not display any gear selector position until the condition is resolved
or until the ignition switch is turned to the Off position, whichever occurs first.
- Resolved Circuit - If the transmission range sensor mux circuit is resolved, the cluster circuitry
controls the gear selector indicator display based upon the resistance value of the hard wired input
from the transmission range sensor. If the cluster is configured for an automatic transmission with a
transmission range sensor input and detects a short to ground or an open in the transmission
range sensor mux input, the instrument cluster circuitry will not display any gear selector position in
the VFD. The VFD display for the short-to-ground and open circuit conditions will continue until the
condition is resolved or until the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gear selector indicator
VFD will display all of its characters at once during the VFD portion of the test to confirm the
functionality of the VFD and the cluster control circuitry.
On models with a TCM, the TCM continually monitors the transmission range sensor, then sends
the proper gear selector indicator position messages to the instrument cluster. On models without a
TCM, the instrument cluster continually monitors the hard wired transmission range sensor
multiplexed input.
On models with a TCM, for proper diagnosis of the transmission range sensor, the TCM, the PCI
data bus, or the electronic message inputs to the instrument cluster that control the gear selector
indicator, a diagnostic scan tool is required.

Temperature Warning Indicator - A/T: Description and Operation
A transmission over-temperature indicator is standard equipment on all instrument clusters.
However, on vehicles not equipped with an optional automatic transmission, this indicator is
electronically disabled. This indicator is located on the left side of the instrument cluster, to the left
of the fuel gauge.
The transmission over-temperature indicator consists of a stencil-like cutout of the text "TRANS
TEMP" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. A red Light Emitting
Diode (LED) behind the cutout in the opaque layer of the overlay causes the "TRANS TEMP" text
to appear in red through the translucent outer layer of the overlay when the indicator is illuminated
from behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The
transmission over-temperature indicator is serviced as a unit with the instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
transmission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus.
The transmission over-temperature indicator Light Emitting Diode (LED) is completely controlled by
the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the
instrument cluster receives a battery current input on the fused ignition switch output (run-start)
circuit. Therefore, the LED will always be off when the ignition switch is in any position except On
or Start. The LED only illuminates when it is provided a path to ground by the instrument cluster
transistor. The instrument cluster will turn on the transmission over-temperature indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-On Message - Each time the cluster receives a trans over-temp lamp-on
message from the PCM indicating that the transmission fluid temperature is 135° C (275° F) or
higher, the indicator will be illuminated and a single chime tone is sounded. The indicator remains
illuminated until the cluster receives a trans over-temp lamp-off message from the PCM, or until the
ignition switch is turned to the Off position, whichever occurs first. The chime tone feature will only
repeat during the same ignition cycle if the transmission over-temperature indicator is cycled off
and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the transmission
over-temperature indicator will be turned on, then off again during the bulb check portion of the test
to confirm the functionality of the LED and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition. The PCM then sends the proper trans over-temp lamp-on or lamp-off
messages to the instrument cluster. If the instrument cluster turns on the transmission
over-temperature indicator due to a high transmission oil temperature condition, it may indicate that
the transmission and/or the transmission cooling system are being overloaded or that they require
service. For further diagnosis of the transmission over-temperature indicator or the instrument
cluster circuitry that controls the LED.
For proper diagnosis of the transmission temperature sensor, the PCM, the PCI data bus, or the
electronic message inputs to the instrument cluster that control the transmission over-temperature
indicator, a diagnostic scan tool is required.

Four Wheel Drive Indicator Lamp: Description and Operation
A service 4WD indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional four-wheel drive system and electronically shifted transfer case, this
indicator is electronically disabled. The service 4WD indicator consists of the text "SERV 4WD",
which appears in the lower portion of the odometer/trip odometer Vacuum Fluorescent Display
(VFD) unit.
The odometer/trip odometer VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial
face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "SERV 4WD" appears in an amber color and at the same
lighting level as the odometer/trip odometer information when it is illuminated by the instrument
cluster electronic circuit board. The service 4WD indicator is serviced as a unit with the VFD in the
instrument cluster.
The service 4WD indicator gives an indication to the vehicle operator when the Transfer Case
Control Module (TCCM) has recorded a Diagnostic Trouble Code (DTC) for an electronic transfer
case circuit or component malfunction. This indicator is controlled by the instrument cluster circuit
board based upon cluster programming and electronic messages received by the cluster from the
TCCM over the Programmable Communications Interface (PCI) data bus.
The service 4WD indicator is completely controlled by the instrument cluster logic circuit, and that
logic will only allow this indicator to operate when the instrument cluster receives a battery current
input on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
service 4WD indicator for the following reasons:
- Service 4WD Lamp-On Message - Each time the cluster receives a service 4WD lamp-on
message from the TCCM, the indicator will be illuminated. The indicator remains illuminated until
the cluster receives a service 4WD lamp-off message from the TCCM, or until the ignition switch is
turned to the Off position, whichever occurs first.
- Communication Error - If the cluster receives no messages from the TCCM for five seconds, the
service 4WD indicator is illuminated by the instrument cluster to indicate a loss of TCCM
communication. The indicator remains controlled and illuminated by the cluster until a valid
message is received from the TCCM.
- Actuator Test - Each time the cluster is put through the actuator test, the service 4WD indicator
will be turned on, then off again during the VFD portion of the test to confirm the functionality of the
VFD and the cluster control circuitry.
The TCCM continually monitors the electronic transfer case switch and circuits to determine the
condition of the system. The TCCM then sends the proper lamp-on or lamp-off messages to the
instrument cluster.
For proper diagnosis of the TCCM, the PCI data bus, or the electronic message inputs to the
instrument cluster that control the service 4WD indicator, a diagnostic scan tool is required.

Bell Housing: Testing and Inspection
CLUTCH HOUSING
The clutch housing maintains alignment between the crankshaft and transmission input shaft.
Misalignment can cause clutch noise, hard shifting, incomplete release and chatter. Also premature
pilot bearing, cover release fingers and clutch disc wear. In severe cases, it can cause premature
wear of the transmission input shaft and front bearing.
NOTE: Only the NV4500 clutch housing can be checked using the following bore and face runout
procedures. The NV5600 clutch housing is a integral part of the transmission and can only be
checked off the vehicle.
CLUTCH HOUSING BORE RUNOUT
CAUTION: On diesel engines if housing bore runout exceeds 0.015 inch, the clutch
housing/transmission adapter plate must be replaced. On gas engines if housing bore runout
exceeds 0.053 inch the clutch housing must be replaced.
NOTE: Offset dowels are available for gas engines to correct housing bore runout. They are not
available for diesel engines.
1. Remove the clutch housing. 2. Remove the clutch cover and disc.
3. Replace one of the flywheel bolts with an appropriate size threaded rod (3) that is 10 inch (25.4
cm) long. The rod will be used to mount the dial
indicator.
4. Remove release fork from the clutch housing. 5. Install clutch housing. Tighten the housing bolts
nearest the alignment dowels first.
6. Mount dial indicator (2) on the threaded rod (1) and position indicator plunger (3) on the clutch
housing bore (4).

Component Information > Testing and Inspection > Page 4601
7. Rotate crankshaft until indicator plunger is at the top of the housing bore (1). Zero the indicator
at this point. 8. Rotate crankshaft and record indicator readings at eight points (45° apart) around
the bore. Take measurement at least twice for accuracy.
9. Subtract each reading from the one 180° opposite to determine runout and direction. Bore runout
example:
^ 0.000 - (-0.007) = 0.007 inch
^ +0.002 - (-0.010) = 0.012 inch
^ +0.004 - (-0.005) = 0.009 inch
^ -0.001 - (+0.001) = -0.002 inch
In this example the largest or Total Indicator Reading (TIR) difference is 0.012 inch. This means
the housing bore is offset from the crankshaft centerline by 0.006 inch which is 1/2 of 0.012 inch.
The dowels (2) needed to correct this have an offset of 0.007 inch.
Remove housing and install dowels with the slotted side facing out so they can be turned with a
screwdriver. Then install the housing and mount the dial indicator and check bore runout again.
Rotate the dowels until the TIR is less than 0.010 inch.
Clutch Housing Face Runout
1. Position dial indicator (2) towards the housing face with indicator plunger (1) on the rim of the
housing bore. 2. Rotate crankshaft until indicator plunger is at the 10 O'clock position and zero the
dial indicator.

Component Information > Testing and Inspection > Page 4602
3. Measure and record face runout (1) readings at four points 90° apart. Take measurement at
least twice for accuracy. 4. Subtract lowest reading from highest to determine total runout. If low
reading was minus 0.004 inch and highest reading was plus 0.009 inch
the total runout is 0.013 inch.
NOTE: Maximum acceptable face runout is 0.010 inch.
To correct this example the shims needed between the clutch housing and transmission are: ^
0.009 inch at the 0.000 corner
^ 0.012 inch at the -0.003 corner
^ 0.013 inch at the -0.004 corner
After installing the clutch assembly and housing, tighten the housing bolts nearest the alignment
dowels first.
NOTE: Shims can be made from shim stock or similar materials of the required thickness.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

Operation
Power Take-Off: Description and Operation
This Powertrain Control Module (PCM) input is used only on models equipped with aftermarket
Power Take Off (PTO) units.
The input is used only to tell the PCM (or ECM-Diesel) that the PTO has been engaged. The PCM
(or ECM) will disable (temporarily shut down) certain OBD II diagnostic trouble codes when the
PTO is engaged.
JTEC and NGC Engine Controllers: When the aftermarket PTO switch has been engaged, a 12V +
signal is sent through circuit G113 to PCM pin A13. The PCM will then sense and determine that
the PTO has been activated. CM 845 or CM 848 Diesel Engine Controllers: When the aftermarket
PTO switch has been engaged, a 12V + signal is sent through circuit G113 to ECM pin B38. The
ECM will then sense and determine that the PTO has been activated.

Control Module: Description and Operation
The Transmission Control Module (TCM) (2) may be sub-module within the Powertrain Control
Module (PCM) (3).
Or, for vehicles with a diesel engine, the Engine Control Module (ECM) (1). The PCM, and TCM
when equipped, is located at the right rear of the engine compartment, near the right inner fender.
The Transmission Control Module (TCM) controls all electronic operations of the transmission. The
TCM receives information regarding vehicle operation from both direct and indirect inputs, and
selects the operational mode of the transmission. Direct inputs are hard wired to, and used
specifically by the TCM. Indirect inputs are shared with the TCM via the vehicle communication
bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure

Dodge Workshop Manuals > Transmission and Drivetrain > Relays and Modules - Transmission and Drivetrain > Relays
and Modules - A/T > Control Module, A/T > Component Information > Description and Operation > Page 4627
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request Some examples of TCM indirect outputs are:
- Transmission Temperature (to PCM)
- PRNDL Position (to cluster/CCN) In addition to monitoring inputs and controlling outputs, the TCM
has other important responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed.
BATTERY FEED
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain memory in the TCM. When the battery (B+) is disconnected, this memory is
lost. When the battery (B+) is restored, this memory loss is detected by the TCM and a Diagnostic
Trouble Code (DTC) is set.
CLUTCH VOLUME INDEXES (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur.
Gear ratios can be determined by using the Scan Tool and reading the Input/Output Speed Sensor
values in the "Monitors" display Gear ratio can be obtained by dividing the Input Speed Sensor
value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Transmission and Drivetrain > Relays and Modules - Transmission and Drivetrain > Relays
and Modules - A/T > Control Module, A/T > Component Information > Description and Operation > Page 4628
In direct drive (3rd gear), the gear ratio changes to 1:1. The gear ratio changes as clutches are
applied and released. By monitoring the length of time it takes for the gear ratio to change following
a shift request, the TCM can determine the volume of fluid used to apply or release a friction
element.
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Certain mechanical problems within the input clutch assembly can cause inadequate or
out-of-range element volumes. Also, defective Input/Output Speed Sensors and wiring can cause
these conditions. The following chart identifies the appropriate clutch volumes and when they are
monitored/updated:
SHIFT SCHEDULES
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following:
- Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

Dodge Workshop Manuals > Transmission and Drivetrain > Relays and Modules - Transmission and Drivetrain > Relays
and Modules - A/T > Control Module, A/T > Component Information > Description and Operation > Page 4629
As driving conditions change, the TCM appropriately adjusts the shift schedule. Refer to the chart
to determine the appropriate operation expected, depending on driving conditions.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Transmission and Drivetrain > Relays and Modules - Transmission and Drivetrain > Relays
and Modules - A/T > Transmission Control System Relay, A/T > Component Information > Diagrams > Diagram Information
and Instructions > Page 4635
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagrams may appear to be

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

and Instructions > Page 4638
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Transmission Control System Relay: Description and Operation Relay-Transmission Control
RELAY-TRANSMISSION CONTROL 45RFE/545RFE
DESCRIPTION
NOTE: The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power
to the solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off", no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Control Module: Description and Operation
The Transfer Case Control Module (TCCM) (2) is a microprocessor-based assembly, controlling
the 4X4 transfer case shift functions via the actuation of a shift motor and utilizing the feedback of a
mode sensor assembly. Communication is via the PCI serial bus. Inputs include user selectable
4X4 modes that include 2WD, AWD, 4HI, 4LO, and Neutral. The logic and driver circuitry is
contained in a molded plastic housing with an embedded heat-sink and is located behind the left
side of the lower instrument panel (1).
The Transfer Case Control Module (TCCM) utilizes the input from the transfer case mounted mode
sensor, the instrument panel mounted selector switch, and the following information from the
vehicle's PCI serial bus to determine if a shift is allowed.
- Engine RPM and Vehicle Speed
- Diagnostic Requests
- Manual Transmission and Brake Applied
- PRNDL
- Ignition Status
- ABS Messages
Once the TCCM determines that a requested shift is allowed, it actuates the bi-directional shift
motor as necessary to achieve the desired transfer case operating mode. The TCCM also monitors
the mode sensor while controlling the shift motor to determine the status of the shift attempt.
Several items can cause the requested shift not to be completed. If the TCCM has recognized a
fault (DTC) of some variety, it will begin operation in one of four Functionality Levels. These levels
are:
- Level Zero - Normal Operation.
- Level One - Only Mode Shifts Are Allowed.
- Level Two - Only Mode Shifts and Shifts Into LOW Are Allowed (No Neutral Shifts Are Allowed).
- Level Three - No Shifts Are Allowed
The TCCM can also be operating in one of three possible power modes. These power modes are:
- Full Power Mode is the normal operational mode of the module. This mode is achieved by normal
PCI bus traffic being present and the ignition being in the RUN position.
- Reduced Power Mode will be entered when the ignition has been powered off. In this state, the
module will shut down power supplied to external devices, and to electronic interface inputs and
outputs. From this state the module can enter either Sleep Mode or Full Power Mode. To enter this
mode, the module must receive an ignition message denoting that the ignition is off, or not receive
any messages for 5 ± 0.5 seconds. To exit this mode, the module must receive one ignition
message that denotes that the ignition is in the RUN position.
- Sleep Mode will be entered, from the Reduced Power Mode, when no PCI traffic has been
sensed for 20 ± 1 seconds. If during Sleep Mode the module detects PCI bus traffic, it will revert to
the Reduced Power mode while monitoring for ignition messages. It will remain in this state as long
as there is traffic other than run or start messages, and will return to Sleep mode if the bus goes
without traffic for 20 ± 1 seconds.
SHIFT REQUIREMENTS
If the TCCM is in full power mode and at functionality level zero, it uses the following criteria to
determine if a shift is allowed.
If any of the driver controllable conditions are not met once the shift request is recognized, the
TCCM will solidly illuminate the source position's LED and flash the desired position's LED for all
shifts except NEUTRAL. The NEUTRAL shift LED strategy will be discussed later.
Mode shifts will be allowed regardless of transmission gear or vehicle speed, whenever the
following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- A change in the Selector switch state indicates that a mode shift has been requested.
- A valid mode sensor signal is being sensed by the TCCM.

and Modules - Transfer Case > Control Module, Transfer Case > Component Information > Locations > Page 4667
- Proper transmit/receive messages are occurring on the PCI bus.
- Ignition key switch is in the RUN position.
Range shifts will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- A change in the Selector Switch state indicating a range shift has been requested.
- Transmission in NEUTRAL signal must be recognized for atleast 1.5 seconds ± 100 msec.
(Automatic transmissions only)
- Proper transmit/receive messages are occurring on the PCI bus.
- Clutch signal is recognized for 500 msec ± 50 msec (Manual transmissions only).
- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position.
- A valid mode sensor signal is being sensed by the TCCM.
A shift into transfer case Neutral will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- The recessed Neutral Selection switch has been depressed continuously for 4.0 seconds ± 100
msec while all shift conditions have been continuously met.
- Transmission in NEUTRAL signal recognized from the bus. (Automatic transmissions only)
- Clutch signal is recognized from the bus (Manual transmissions only).
- Proper message transmissions/receptions are occurring on the PCI bus.
- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position, engine off.
- Foot Brake is applied.
- A valid mode sensor signal is being sensed by the TCCM.
A shift out of transfer case Neutral will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- The recessed Neutral Selection switch has been depressed continuously for 1.0 seconds ± 100
msec while all shift conditions have been continuously met.
- Transmission in NEUTRAL signal recognized from the bus.(Automatic transmissions only)
- Clutch signal is recognized from the bus (Manual transmissions only).
- Proper message transmissions/receptions are occurring on the PCI bus.
- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position.
- Foot Brake is applied.
- A valid mode sensor signal is being sensed by the TCCM.
SHIFT SEQUENCES
Once all the driver controllable conditions for the requested shift have been met, the TCCM begins
a shift timer with a maximum duration of 1 second per 'D' channel transition. If the shift timer
expires before the TCCM recognizes to correct mode sensor code, the shift is considered to have
been blocked. The blocked shift will increment the blocked shift counter by one. The TCCM
strategy for handling blocked shifts will be described later. The process the TCCM performs for the
various shifts will be described first.
RANGE AND MODE SHIFTS
The process for performing all the range and mode shifts are the same. The following steps
describe the process.
- Allow time for Selector Switch debounce; 250 msec ± 50 msec.
- Extinguish the source gear's LED while flashing desired transfer case position's LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec per 'D' channel transition in the
destination gear's direction while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Solidly illuminate the selected gear's LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 seconds ± 100 msec. per 'D'
channel. The TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the
desired position.
The exception to the preceding sequence is when a shift from 4L to 2WD/AWD is requested. If
2WD/AWD is requested from the 4L position, the transfer case is first driven to the 4H position. If
the 4H position is reached, the transfer case is then driven back to the 2WD/AWD position and the
shift is considered complete. If the transfer case does not reach any the 4H position, but is in the
2WD/AWD 'D' channel, or the 2WD/AWD between gear position on the 4H side of 2WD/AWD, the
shift is also considered complete.
SHIFT OUT OF NEUTRAL
The following steps describe the process for a shift out of NEUTRAL.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Transmission and Drivetrain > Relays and Modules - Transmission and Drivetrain > Relays
and Modules - Transfer Case > Control Module, Transfer Case > Component Information > Locations > Page 4668
- Extinguish the Neutral LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec toward the transfer case 4H mode
position while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Extinguish the Neutral LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 ± seconds 100 msec. The
TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the desired position.
- When the Neutral button is released, if the 4H position is the desired position, the shift is
complete. Illuminate the 4H LED.
- Otherwise when the Neutral button is released, if all of the shift requirements are being met then
engage the shift motor towards the desired position for 1 second ± 100 msec per 'D' channel, (if
requirements for shifting are not met, illuminate the 4H LED and flash the destination LED as an
indication to the driver that all of the driver controllable shift conditions are not being met). If this
requires another range or mode shift, begin the range/mode shift process.
- If the desired mode sensor code is not received after the shift timer expires (i.e. a blocked or other
condition exists), refer to the Blocked Shift Strategy.
BLOCKED SHIFT STRATEGY
When a shift is commanded, the shift motor will be driven towards its destination position, except in
the case of shifting out of Neutral if 4L was selected (the transfer case will shift to the 4H position
first, before proceeding to 4L). If the shift is blocked on the way to the destination, the TCCM may
attempt to drive the motor back to the original position. This process will be allowed to occur 5
times. If the transfer case has reached a non-NEUTRAL 'D' channel during the shift re-attempts,
the LED for the achieved gear position is illuminated and the shift attempts are stopped. To
re-attempt the desired shift, the selector switch will need to be rotated to the current position until
the switch debounce timer expires then a shift will need to be requested again.
At the end of the 5th blocked attempt, the shift motor is driven towards the last known 'D' channel
position. If this motor drive allows the transfer case to reach the 2WD/AWD 'D' channel, or the
2WD/AWD between gear position on the 4H side of 2WD/AWD, the shift is considered complete
and the shift attempts are ended.
If the mode sensor is in the NEUTRAL region at the expiration of the shift timer, the TCCM will
continue to make the shift attempts according to the blocked shift strategy independent of whether
or not the driver controlled conditions are met.
For shifts from NEUTRAL, if all 5 attempts fail to reach the desired position (which by default is
4H), the motor will be driven to stall in the direction of 4H or 4L, depending on the achieved
position. If the transfer case has reached the 2WD/AWD or 4L between gear position nearest the
NEUTRAL positions and the shift conditions are no longer being met, the transfer case will be
driven toward the corresponding 'D' channel. Otherwise, the transfer case will be driven in the
direction opposite the last attempt with the desired target being 4H or 4L.
If the transfer case reaches the 2WD/AWD 'D' channel when being driven in the 4H direction, then
one final 1.0 second drive toward 4H is attempted. If the transfer case then reaches any of the 4H
positions, the shift is considered complete and the 4H LED is illuminated. If the transfer case is still
the 2WD/AWD position, the shift is considered complete and the 2WD/AWD LED is illuminated.
NOTE: If after the 5th blocked shift and reversal attempt, if the transfer case position is in the
NEUTRAL region, shift attempts will continue until a non-NEUTRAL 'D' channel is reached.
SHIFT REVERSAL TARGETS
If the shift timer expires (1 second per 'D' channel) and the transfer case has not reached the
desired position, all shifts will attempt to return to their original position with the exceptions of:
- If the intended shift is going to the High rail from Low and can't make it, but it can make the
2WD/AWD position, the motor stops at that position. The TCCM will not attempt to cross back over
NEUTRAL if it does not have to. This means that there was a block on the first attempt to go to 4H
and the transfer case has made it through NEUTRAL to a known good position, then the motor will
go back only to the 2WD/4WD position and execute the remainder of the attempts from there.
- For shifts out of NEUTRAL, any time a shift is commanded out of NEUTRAL, the system needs to
get out. The TCCM should never go to NEUTRAL unless the driver is commanding it and all
required conditions are being met
ENCODER DRIFT CORRECTION
Whenever a shift is completed, the TCCM stores the position in memory as the transfer case's
intended position. The TCCM continuously monitors the mode sensor and if the mode sensor drifts
toward into a NEUTRAL region sensor position for 2.0 seconds, the TCCM will perform a motor
drive to correct the drift. The transfer case will be driven toward the intended position for 1.0
seconds 100 msec. The TCCM will wait for 2.0 seconds ± 50 msec . and repeat the attempt to shift
to the desired position. This will continue until the intended position is reached.
SHIFT MOTOR BRAKING
Two modes of shift motor braking are employed to improve shift performance, static and dynamic.
Static shift motor braking is utilized under the
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Transmission and Drivetrain > Relays and Modules - Transmission and Drivetrain > Relays
and Modules - Transfer Case > Control Module, Transfer Case > Component Information > Locations > Page 4669
following conditions:
- Whenever the transfer case is in the 2WD/AWD or 4L 'D' channel position.
- Whenever an invalid mode sensor code is present. Static motor braking is achieved by applying
+12V on both shift motor wires. NOTE: Static Shift Motor Braking is independent of ignition key
position.
SHIFT ATTEMPT LIMIT
To protect the transfer case system, the TCCM will impose a limit on the number of shifts that can
occur over a calibrated time period. The system will monitor the number of 'D' channel segment
transitions that occur in any 30 second time period. If the number of segment transitions is 30 or
greater, the system will go into a default mode. The default mode of operation for shifting is that the
number of allowed 'D' channel transitions permitted to occur will be 3 over each 15 second ± 100
msec calibrated window of time. After 5 minutes ± 100 msec, the motor can be assumed to have
cooled down and the system will revert to normal operation. The following rules also apply to the
shift limit:
- The attempt limit will not prevent shifts coming out of NEUTRAL, they will be allowed regardless
of the counter/timer.
- Any shift that is in progress when the counter reaches a maximum count in time will be allowed to
complete before the default mode is entered. D-channel transitions during this period will not be
counted towards the default mode limit.
- A block, regardless of the direction, whether towards destination or back towards reversal target
(shift timer expiring), will count as a value of 2 transitions towards the 30 segment transitions to go
into default mode as defined above. Current attempt limit values are 30 transitions in 30 seconds
and default mode values are 3 transitions every 15 seconds for 5 minutes.

Fluid Pressure Sensor/Switch: Description and Operation
SENSOR-LINE PRESSURE
DESCRIPTION
The TCM utilizes a closed-loop system to control transmission line pressure. The system contains
a variable force style solenoid, the Pressure Control Solenoid, mounted on the side of the solenoid
and pressure switch assembly. The solenoid is duty cycle controlled by the TCM to vent the
unnecessary line pressure supplied by the oil pump back to the sump. The system also contains a
variable pressure style sensor, the Line Pressure Sensor, which is a direct input to the TCM. The
line pressure solenoid monitors the transmission line pressure and completes the feedback loop to
the TCM. The TCM uses this information to adjust its control of the pressure control solenoid to
achieve the desired line pressure.
OPERATION
The TCM calculates the desired line pressure based upon inputs from the transmission and engine.
The TCM calculates the torque input to the transmission and uses that information as the primary
input to the calculation. The line pressure is set to a predetermined value during shifts and when
the transmission is in the PARK and NEUTRAL positions. This is done to ensure consistent shift
quality. During all other operation, the actual line pressure is compared to the desired line pressure
and adjustments are made to the pressure control solenoid duty cycle.

Overdrive Switch: Description and Operation
SWITCH-TOW/HAUL OVERDRIVE
DESCRIPTION
The tow/haul overdrive OFF (control) switch is located in the shift lever arm. The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the tow/haul overdrive
OFF mode to be entered and the Tow/Haul lamp to be illuminated. Pressing the switch a second
time causes normal overdrive operation to be restored and the tow/haul lamp to be turned off. The
tow/haul overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the tow/haul overdrive switch is turned to the OFF position, or when illuminated by the
transmission control module.

Transmission Position Switch/Sensor: Description and Operation
SENSOR-TRANSMISSION RANGE
DESCRIPTION
The Transmission Range Sensor (TRS) is part of the solenoid module, which is mounted to the top
of the valve body inside the transmission. The Transmission Range Sensor (TRS) has five switch
contact pins that: ^
Determine shift lever position
^ Supply ground to the Starter Relay in Park and Neutral only.
^ Supply +12 V to the backup lamps in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

SENSOR-INPUT SPEED
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following: ^
Transmission gear ratio
^ Speed ratio error detection
^ CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following: . Torque converter clutch slippage . Torque converter element speed ratio.

SENSOR-TRANSMISSION TEMPERATURE
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: ^
Battery (ambient) temperature
^ Engine coolant temperature
^ In-gear run time since start-up

SWITCH-SELECTOR
DESCRIPTION
The selector switch assembly (1) is mounted in the left side of the vehicle's Instrument Panel (IP)
and consists of a rotary knob connected to a resistive network for the mode and range shift
selections. Also located in this assembly is a recessed, normally open momentary switch for
making shifts into and out of transfer case NEUTRAL. A pen, or similar instrument, is used to make
a NEUTRAL shift selection, thus reducing the likelihood of an inadvertent shift request.
The selector switch also contains four light emitting diode's (LED's) to indicate the transfer case
position and whether a shift is in progress.
OPERATION
As the position of the selector switch varies, the resistance between the Mode Sensor supply
voltage pin and the Mode Sensor output will vary. Hardware, software, and calibrations within the
Transfer Case Control Module (TCCM) are provided that interpret the selector switch resistance as
given in the table below:
SELECTOR SWITCH INTERPRETATION
SELECTOR SWITCH INTERPRETATION
For resistances between the ranges B-E shown for each valid position (T-Case NEUTRAL, 4LO,
4HI, 2WD), the TCCM may interpret the resistance as: ^
either of the neighboring valid positions.
^ as an invalid fault position.
For resistances between the ranges E and F shown for 2WD and in-between positions, the TCCM
may interpret the resistance as: ^
the 2WD position.
^ an invalid fault position.
^ a valid in-between position.
For resistances between the ranges F and G shown for in-between positions and fault condition
(open), the TCCM may interpret the resistance as: ^
a valid in-between position.
^ an invalid fault position.

For resistances between the ranges A and B shown for the fault condition (short) and, T-Case
NEUTRAL, the TCCM may interpret the resistance as: ^
the T-Case NEUTRAL position.
^ an invalid fault position.
The LED's in the selector assembly are illuminated/flashed in the following manner to indicate a
particular condition or state. ^
A solidly illuminated LED indicates a successfully completed shift and the current operating mode
of the transfer case. While a shift has been requested but not yet completed, the LED for the
desired transfer case position is flashed.
^ A flashing operating mode LED for the desired gear indicates that a shift to that position has been
requested, but all of the driver controllable conditions have not been met. This is in an attempt to
notify the driver that the transmission needs to be put into NEUTRAL, the vehicle speed is too
great, or some other condition outlined (other than a diagnostic failure that would prevent this shift)
elsewhere is not met. Note that this flashing will continue indefinitely until the conditions are
eventually met, or the selector switch position is changed, or if diagnostic routines no longer allow
the requested shift.
^ If the driver attempts to make a shift into transfer case NEUTRAL, and any of the driver
controllable conditions are not met, the request will be ignored until all of the conditions are met or
until the NEUTRAL select button is released. Additionally the neutral lamp will flash, or begin to
flash while the button is depressed and operator controllable conditions are not being met. All of
the LED's except the Neutral will flash if any of the operator controllable conditions for shifting are
not met while the Neutral button is depressed. This "toggle" type of feature is necessary because
the TCCM would interpret another request immediately after the shift into transfer case NEUTRAL
has completed.
^ No LED's illuminated indicate a fault in the transfer case control system.

SENSOR-MODE
DESCRIPTION
The transfer case mode sensor (1) is an electronic device whose output can be interpreted to
indicate the shift motor shaft's rotary position. The sensor consists of a magnetic ring and four Hall
Effect Transistors to create a 4 channel digital device (non-contacting) whose output converts the
motor shaft position into a coded signal. The TCCM must supply 5VDC (+/- 0.5v) to the sensor and
monitor the shift motor position. The four channels are denoted A, B. C, and D. The sensor is
mechanically linked to the shaft of the cam which causes the transfer case shifting. The mode
sensor draws less than 53 mA.
OPERATION
During normal vehicle operation, the Transfer Case Control Module (TCCM) monitors the mode
sensor outputs at least every 250 (+/-50) milliseconds when the shift motor is stationary and 400
microseconds when the shift motor is active. A mode sensor signal between 3.8 Volts and 0.8 Volts
is considered to be undefined.
Refer to SECTOR ANGLES vs. TRANSFER CASE POSITION for the relative angles of the transfer
case shift sector versus the interpreted transfer case gear operating mode. Refer to MODE
SENSOR CHANNEL STATES for the sensor codes returned to the TCCM for each transfer case
mode sensor position. The various between gears positions can also be referred as the transfer
case's coarse position. These coarse positions come into play during shift attempts.

Control Module: Description and Operation
The Transfer Case Control Module (TCCM) (2) is a microprocessor-based assembly, controlling
the 4X4 transfer case shift functions via the actuation of a shift motor and utilizing the feedback of a
mode sensor assembly. Communication is via the PCI serial bus. Inputs include user selectable
4X4 modes that include 2WD, AWD, 4HI, 4LO, and Neutral. The logic and driver circuitry is
contained in a molded plastic housing with an embedded heat-sink and is located behind the left
side of the lower instrument panel (1).
The Transfer Case Control Module (TCCM) utilizes the input from the transfer case mounted mode
sensor, the instrument panel mounted selector switch, and the following information from the
vehicle's PCI serial bus to determine if a shift is allowed.
- Engine RPM and Vehicle Speed
- Diagnostic Requests
- Manual Transmission and Brake Applied
- PRNDL
- Ignition Status
- ABS Messages
Once the TCCM determines that a requested shift is allowed, it actuates the bi-directional shift
motor as necessary to achieve the desired transfer case operating mode. The TCCM also monitors
the mode sensor while controlling the shift motor to determine the status of the shift attempt.
Several items can cause the requested shift not to be completed. If the TCCM has recognized a
fault (DTC) of some variety, it will begin operation in one of four Functionality Levels. These levels
are:
- Level Zero - Normal Operation.
- Level One - Only Mode Shifts Are Allowed.
- Level Two - Only Mode Shifts and Shifts Into LOW Are Allowed (No Neutral Shifts Are Allowed).
- Level Three - No Shifts Are Allowed
The TCCM can also be operating in one of three possible power modes. These power modes are:
- Full Power Mode is the normal operational mode of the module. This mode is achieved by normal
PCI bus traffic being present and the ignition being in the RUN position.
- Reduced Power Mode will be entered when the ignition has been powered off. In this state, the
module will shut down power supplied to external devices, and to electronic interface inputs and
outputs. From this state the module can enter either Sleep Mode or Full Power Mode. To enter this
mode, the module must receive an ignition message denoting that the ignition is off, or not receive
any messages for 5 ± 0.5 seconds. To exit this mode, the module must receive one ignition
message that denotes that the ignition is in the RUN position.
- Sleep Mode will be entered, from the Reduced Power Mode, when no PCI traffic has been
sensed for 20 ± 1 seconds. If during Sleep Mode the module detects PCI bus traffic, it will revert to
the Reduced Power mode while monitoring for ignition messages. It will remain in this state as long
as there is traffic other than run or start messages, and will return to Sleep mode if the bus goes
without traffic for 20 ± 1 seconds.
SHIFT REQUIREMENTS
If the TCCM is in full power mode and at functionality level zero, it uses the following criteria to
determine if a shift is allowed.
If any of the driver controllable conditions are not met once the shift request is recognized, the
TCCM will solidly illuminate the source position's LED and flash the desired position's LED for all
shifts except NEUTRAL. The NEUTRAL shift LED strategy will be discussed later.
Mode shifts will be allowed regardless of transmission gear or vehicle speed, whenever the
following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- A change in the Selector switch state indicates that a mode shift has been requested.
- A valid mode sensor signal is being sensed by the TCCM.

- A valid mode sensor signal is being sensed by the TCCM.
A shift into transfer case Neutral will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- The recessed Neutral Selection switch has been depressed continuously for 4.0 seconds ± 100
msec while all shift conditions have been continuously met.
- Transmission in NEUTRAL signal recognized from the bus. (Automatic transmissions only)
- Clutch signal is recognized from the bus (Manual transmissions only).

- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position, engine off.
- Foot Brake is applied.
- A valid mode sensor signal is being sensed by the TCCM.
A shift out of transfer case Neutral will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- The recessed Neutral Selection switch has been depressed continuously for 1.0 seconds ± 100
msec while all shift conditions have been continuously met.
- Transmission in NEUTRAL signal recognized from the bus.(Automatic transmissions only)
- Clutch signal is recognized from the bus (Manual transmissions only).
- Proper message transmissions/receptions are occurring on the PCI bus.
- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position.
- Foot Brake is applied.
- A valid mode sensor signal is being sensed by the TCCM.
SHIFT SEQUENCES
Once all the driver controllable conditions for the requested shift have been met, the TCCM begins
a shift timer with a maximum duration of 1 second per 'D' channel transition. If the shift timer
expires before the TCCM recognizes to correct mode sensor code, the shift is considered to have
been blocked. The blocked shift will increment the blocked shift counter by one. The TCCM
strategy for handling blocked shifts will be described later. The process the TCCM performs for the
various shifts will be described first.
RANGE AND MODE SHIFTS
The process for performing all the range and mode shifts are the same. The following steps
describe the process.
- Allow time for Selector Switch debounce; 250 msec ± 50 msec.
- Extinguish the source gear's LED while flashing desired transfer case position's LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec per 'D' channel transition in the
destination gear's direction while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Solidly illuminate the selected gear's LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 seconds ± 100 msec. per 'D'
channel. The TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the
desired position.
The exception to the preceding sequence is when a shift from 4L to 2WD/AWD is requested. If
2WD/AWD is requested from the 4L position, the transfer case is first driven to the 4H position. If
the 4H position is reached, the transfer case is then driven back to the 2WD/AWD position and the
shift is considered complete. If the transfer case does not reach any the 4H position, but is in the
2WD/AWD 'D' channel, or the 2WD/AWD between gear position on the 4H side of 2WD/AWD, the
shift is also considered complete.
SHIFT OUT OF NEUTRAL
The following steps describe the process for a shift out of NEUTRAL.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Transmission and Drivetrain > Transfer Case > Control Module, Transfer Case > Component
Information > Locations > Page 4748
- Extinguish the Neutral LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec toward the transfer case 4H mode
position while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Extinguish the Neutral LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 ± seconds 100 msec. The
TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the desired position.
- When the Neutral button is released, if the 4H position is the desired position, the shift is
complete. Illuminate the 4H LED.
- Otherwise when the Neutral button is released, if all of the shift requirements are being met then
engage the shift motor towards the desired position for 1 second ± 100 msec per 'D' channel, (if
requirements for shifting are not met, illuminate the 4H LED and flash the destination LED as an
indication to the driver that all of the driver controllable shift conditions are not being met). If this
requires another range or mode shift, begin the range/mode shift process.
- If the desired mode sensor code is not received after the shift timer expires (i.e. a blocked or other
condition exists), refer to the Blocked Shift Strategy.
BLOCKED SHIFT STRATEGY
When a shift is commanded, the shift motor will be driven towards its destination position, except in
the case of shifting out of Neutral if 4L was selected (the transfer case will shift to the 4H position
first, before proceeding to 4L). If the shift is blocked on the way to the destination, the TCCM may
attempt to drive the motor back to the original position. This process will be allowed to occur 5
times. If the transfer case has reached a non-NEUTRAL 'D' channel during the shift re-attempts,
the LED for the achieved gear position is illuminated and the shift attempts are stopped. To
re-attempt the desired shift, the selector switch will need to be rotated to the current position until
the switch debounce timer expires then a shift will need to be requested again.
At the end of the 5th blocked attempt, the shift motor is driven towards the last known 'D' channel
position. If this motor drive allows the transfer case to reach the 2WD/AWD 'D' channel, or the
2WD/AWD between gear position on the 4H side of 2WD/AWD, the shift is considered complete
and the shift attempts are ended.
If the mode sensor is in the NEUTRAL region at the expiration of the shift timer, the TCCM will
continue to make the shift attempts according to the blocked shift strategy independent of whether
or not the driver controlled conditions are met.
For shifts from NEUTRAL, if all 5 attempts fail to reach the desired position (which by default is
4H), the motor will be driven to stall in the direction of 4H or 4L, depending on the achieved
position. If the transfer case has reached the 2WD/AWD or 4L between gear position nearest the
NEUTRAL positions and the shift conditions are no longer being met, the transfer case will be
driven toward the corresponding 'D' channel. Otherwise, the transfer case will be driven in the
direction opposite the last attempt with the desired target being 4H or 4L.
If the transfer case reaches the 2WD/AWD 'D' channel when being driven in the 4H direction, then
one final 1.0 second drive toward 4H is attempted. If the transfer case then reaches any of the 4H
positions, the shift is considered complete and the 4H LED is illuminated. If the transfer case is still
the 2WD/AWD position, the shift is considered complete and the 2WD/AWD LED is illuminated.
NOTE: If after the 5th blocked shift and reversal attempt, if the transfer case position is in the
NEUTRAL region, shift attempts will continue until a non-NEUTRAL 'D' channel is reached.
SHIFT REVERSAL TARGETS
If the shift timer expires (1 second per 'D' channel) and the transfer case has not reached the
desired position, all shifts will attempt to return to their original position with the exceptions of:
- If the intended shift is going to the High rail from Low and can't make it, but it can make the
2WD/AWD position, the motor stops at that position. The TCCM will not attempt to cross back over
NEUTRAL if it does not have to. This means that there was a block on the first attempt to go to 4H
and the transfer case has made it through NEUTRAL to a known good position, then the motor will
go back only to the 2WD/4WD position and execute the remainder of the attempts from there.
- For shifts out of NEUTRAL, any time a shift is commanded out of NEUTRAL, the system needs to
get out. The TCCM should never go to NEUTRAL unless the driver is commanding it and all
required conditions are being met
ENCODER DRIFT CORRECTION
Whenever a shift is completed, the TCCM stores the position in memory as the transfer case's
intended position. The TCCM continuously monitors the mode sensor and if the mode sensor drifts
toward into a NEUTRAL region sensor position for 2.0 seconds, the TCCM will perform a motor
drive to correct the drift. The transfer case will be driven toward the intended position for 1.0
seconds 100 msec. The TCCM will wait for 2.0 seconds ± 50 msec . and repeat the attempt to shift
to the desired position. This will continue until the intended position is reached.
SHIFT MOTOR BRAKING
Two modes of shift motor braking are employed to improve shift performance, static and dynamic.
Static shift motor braking is utilized under the
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Transmission and Drivetrain > Transfer Case > Control Module, Transfer Case > Component
Information > Locations > Page 4749
following conditions:
- Whenever the transfer case is in the 2WD/AWD or 4L 'D' channel position.
- Whenever an invalid mode sensor code is present. Static motor braking is achieved by applying
+12V on both shift motor wires. NOTE: Static Shift Motor Braking is independent of ignition key
position.
SHIFT ATTEMPT LIMIT
To protect the transfer case system, the TCCM will impose a limit on the number of shifts that can
occur over a calibrated time period. The system will monitor the number of 'D' channel segment
transitions that occur in any 30 second time period. If the number of segment transitions is 30 or
greater, the system will go into a default mode. The default mode of operation for shifting is that the
number of allowed 'D' channel transitions permitted to occur will be 3 over each 15 second ± 100
msec calibrated window of time. After 5 minutes ± 100 msec, the motor can be assumed to have
cooled down and the system will revert to normal operation. The following rules also apply to the
shift limit:
- The attempt limit will not prevent shifts coming out of NEUTRAL, they will be allowed regardless
of the counter/timer.
- Any shift that is in progress when the counter reaches a maximum count in time will be allowed to
complete before the default mode is entered. D-channel transitions during this period will not be
counted towards the default mode limit.
- A block, regardless of the direction, whether towards destination or back towards reversal target
(shift timer expiring), will count as a value of 2 transitions towards the 30 segment transitions to go
into default mode as defined above. Current attempt limit values are 30 transitions in 30 seconds
and default mode values are 3 transitions every 15 seconds for 5 minutes.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

Four Wheel Drive Indicator Lamp: Description and Operation
A service 4WD indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional four-wheel drive system and electronically shifted transfer case, this
indicator is electronically disabled. The service 4WD indicator consists of the text "SERV 4WD",
which appears in the lower portion of the odometer/trip odometer Vacuum Fluorescent Display
(VFD) unit.
The odometer/trip odometer VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial
face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "SERV 4WD" appears in an amber color and at the same
lighting level as the odometer/trip odometer information when it is illuminated by the instrument
cluster electronic circuit board. The service 4WD indicator is serviced as a unit with the VFD in the
instrument cluster.
The service 4WD indicator gives an indication to the vehicle operator when the Transfer Case
Control Module (TCCM) has recorded a Diagnostic Trouble Code (DTC) for an electronic transfer
case circuit or component malfunction. This indicator is controlled by the instrument cluster circuit
board based upon cluster programming and electronic messages received by the cluster from the
TCCM over the Programmable Communications Interface (PCI) data bus.
The service 4WD indicator is completely controlled by the instrument cluster logic circuit, and that
logic will only allow this indicator to operate when the instrument cluster receives a battery current
input on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
service 4WD indicator for the following reasons:
- Service 4WD Lamp-On Message - Each time the cluster receives a service 4WD lamp-on
message from the TCCM, the indicator will be illuminated. The indicator remains illuminated until
the cluster receives a service 4WD lamp-off message from the TCCM, or until the ignition switch is
turned to the Off position, whichever occurs first.
- Communication Error - If the cluster receives no messages from the TCCM for five seconds, the
service 4WD indicator is illuminated by the instrument cluster to indicate a loss of TCCM
communication. The indicator remains controlled and illuminated by the cluster until a valid
message is received from the TCCM.
- Actuator Test - Each time the cluster is put through the actuator test, the service 4WD indicator
will be turned on, then off again during the VFD portion of the test to confirm the functionality of the
VFD and the cluster control circuitry.
The TCCM continually monitors the electronic transfer case switch and circuits to determine the
condition of the system. The TCCM then sends the proper lamp-on or lamp-off messages to the
instrument cluster.
For proper diagnosis of the TCCM, the PCI data bus, or the electronic message inputs to the
instrument cluster that control the service 4WD indicator, a diagnostic scan tool is required.

SWITCH-SELECTOR
DESCRIPTION
The selector switch assembly (1) is mounted in the left side of the vehicle's Instrument Panel (IP)
and consists of a rotary knob connected to a resistive network for the mode and range shift
selections. Also located in this assembly is a recessed, normally open momentary switch for
making shifts into and out of transfer case NEUTRAL. A pen, or similar instrument, is used to make
a NEUTRAL shift selection, thus reducing the likelihood of an inadvertent shift request.
The selector switch also contains four light emitting diode's (LED's) to indicate the transfer case
position and whether a shift is in progress.
OPERATION
As the position of the selector switch varies, the resistance between the Mode Sensor supply
voltage pin and the Mode Sensor output will vary. Hardware, software, and calibrations within the
Transfer Case Control Module (TCCM) are provided that interpret the selector switch resistance as
given in the table below:
SELECTOR SWITCH INTERPRETATION
SELECTOR SWITCH INTERPRETATION
For resistances between the ranges B-E shown for each valid position (T-Case NEUTRAL, 4LO,
4HI, 2WD), the TCCM may interpret the resistance as: ^
either of the neighboring valid positions.
^ as an invalid fault position.
For resistances between the ranges E and F shown for 2WD and in-between positions, the TCCM
may interpret the resistance as: ^
the 2WD position.
^ an invalid fault position.
^ a valid in-between position.
For resistances between the ranges F and G shown for in-between positions and fault condition
(open), the TCCM may interpret the resistance as: ^
a valid in-between position.
^ an invalid fault position.

For resistances between the ranges A and B shown for the fault condition (short) and, T-Case
NEUTRAL, the TCCM may interpret the resistance as: ^
the T-Case NEUTRAL position.
^ an invalid fault position.
The LED's in the selector assembly are illuminated/flashed in the following manner to indicate a
particular condition or state. ^
A solidly illuminated LED indicates a successfully completed shift and the current operating mode
of the transfer case. While a shift has been requested but not yet completed, the LED for the
desired transfer case position is flashed.
^ A flashing operating mode LED for the desired gear indicates that a shift to that position has been
requested, but all of the driver controllable conditions have not been met. This is in an attempt to
notify the driver that the transmission needs to be put into NEUTRAL, the vehicle speed is too
great, or some other condition outlined (other than a diagnostic failure that would prevent this shift)
elsewhere is not met. Note that this flashing will continue indefinitely until the conditions are
eventually met, or the selector switch position is changed, or if diagnostic routines no longer allow
the requested shift.
^ If the driver attempts to make a shift into transfer case NEUTRAL, and any of the driver
controllable conditions are not met, the request will be ignored until all of the conditions are met or
until the NEUTRAL select button is released. Additionally the neutral lamp will flash, or begin to
flash while the button is depressed and operator controllable conditions are not being met. All of
the LED's except the Neutral will flash if any of the operator controllable conditions for shifting are
not met while the Neutral button is depressed. This "toggle" type of feature is necessary because
the TCCM would interpret another request immediately after the shift into transfer case NEUTRAL
has completed.
^ No LED's illuminated indicate a fault in the transfer case control system.

SENSOR-MODE
DESCRIPTION
The transfer case mode sensor (1) is an electronic device whose output can be interpreted to
indicate the shift motor shaft's rotary position. The sensor consists of a magnetic ring and four Hall
Effect Transistors to create a 4 channel digital device (non-contacting) whose output converts the
motor shaft position into a coded signal. The TCCM must supply 5VDC (+/- 0.5v) to the sensor and
monitor the shift motor position. The four channels are denoted A, B. C, and D. The sensor is
mechanically linked to the shaft of the cam which causes the transfer case shifting. The mode
sensor draws less than 53 mA.
OPERATION
During normal vehicle operation, the Transfer Case Control Module (TCCM) monitors the mode
sensor outputs at least every 250 (+/-50) milliseconds when the shift motor is stationary and 400
microseconds when the shift motor is active. A mode sensor signal between 3.8 Volts and 0.8 Volts
is considered to be undefined.
Refer to SECTOR ANGLES vs. TRANSFER CASE POSITION for the relative angles of the transfer
case shift sector versus the interpreted transfer case gear operating mode. Refer to MODE
SENSOR CHANNEL STATES for the sensor codes returned to the TCCM for each transfer case
mode sensor position. The various between gears positions can also be referred as the transfer
case's coarse position. These coarse positions come into play during shift attempts.

Control Module: Description and Operation
The Transfer Case Control Module (TCCM) (2) is a microprocessor-based assembly, controlling
the 4X4 transfer case shift functions via the actuation of a shift motor and utilizing the feedback of a
mode sensor assembly. Communication is via the PCI serial bus. Inputs include user selectable
4X4 modes that include 2WD, AWD, 4HI, 4LO, and Neutral. The logic and driver circuitry is
contained in a molded plastic housing with an embedded heat-sink and is located behind the left
side of the lower instrument panel (1).
The Transfer Case Control Module (TCCM) utilizes the input from the transfer case mounted mode
sensor, the instrument panel mounted selector switch, and the following information from the
vehicle's PCI serial bus to determine if a shift is allowed.
- Engine RPM and Vehicle Speed
- Diagnostic Requests
- Manual Transmission and Brake Applied
- PRNDL
- Ignition Status
- ABS Messages
Once the TCCM determines that a requested shift is allowed, it actuates the bi-directional shift
motor as necessary to achieve the desired transfer case operating mode. The TCCM also monitors
the mode sensor while controlling the shift motor to determine the status of the shift attempt.
Several items can cause the requested shift not to be completed. If the TCCM has recognized a
fault (DTC) of some variety, it will begin operation in one of four Functionality Levels. These levels
are:
- Level Zero - Normal Operation.
- Level One - Only Mode Shifts Are Allowed.
- Level Two - Only Mode Shifts and Shifts Into LOW Are Allowed (No Neutral Shifts Are Allowed).
- Level Three - No Shifts Are Allowed
The TCCM can also be operating in one of three possible power modes. These power modes are:
- Full Power Mode is the normal operational mode of the module. This mode is achieved by normal
PCI bus traffic being present and the ignition being in the RUN position.
- Reduced Power Mode will be entered when the ignition has been powered off. In this state, the
module will shut down power supplied to external devices, and to electronic interface inputs and
outputs. From this state the module can enter either Sleep Mode or Full Power Mode. To enter this
mode, the module must receive an ignition message denoting that the ignition is off, or not receive
any messages for 5 ± 0.5 seconds. To exit this mode, the module must receive one ignition
message that denotes that the ignition is in the RUN position.
- Sleep Mode will be entered, from the Reduced Power Mode, when no PCI traffic has been
sensed for 20 ± 1 seconds. If during Sleep Mode the module detects PCI bus traffic, it will revert to
the Reduced Power mode while monitoring for ignition messages. It will remain in this state as long
as there is traffic other than run or start messages, and will return to Sleep mode if the bus goes
without traffic for 20 ± 1 seconds.
SHIFT REQUIREMENTS
If the TCCM is in full power mode and at functionality level zero, it uses the following criteria to
determine if a shift is allowed.
If any of the driver controllable conditions are not met once the shift request is recognized, the
TCCM will solidly illuminate the source position's LED and flash the desired position's LED for all
shifts except NEUTRAL. The NEUTRAL shift LED strategy will be discussed later.
Mode shifts will be allowed regardless of transmission gear or vehicle speed, whenever the
following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- A change in the Selector switch state indicates that a mode shift has been requested.
- A valid mode sensor signal is being sensed by the TCCM.

- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position.
- A valid mode sensor signal is being sensed by the TCCM.
A shift into transfer case Neutral will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- The recessed Neutral Selection switch has been depressed continuously for 4.0 seconds ± 100
msec while all shift conditions have been continuously met.
- Transmission in NEUTRAL signal recognized from the bus. (Automatic transmissions only)
- Clutch signal is recognized from the bus (Manual transmissions only).

- Front and rear wheel speed are within 21 km/hr (13 mph).
- The recessed Neutral Selection switch has been depressed continuously for 1.0 seconds ± 100
msec while all shift conditions have been continuously met.
- Transmission in NEUTRAL signal recognized from the bus.(Automatic transmissions only)
- Clutch signal is recognized from the bus (Manual transmissions only).
- Proper message transmissions/receptions are occurring on the PCI bus.
- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position.
- Foot Brake is applied.
- A valid mode sensor signal is being sensed by the TCCM.
SHIFT SEQUENCES
Once all the driver controllable conditions for the requested shift have been met, the TCCM begins
a shift timer with a maximum duration of 1 second per 'D' channel transition. If the shift timer
expires before the TCCM recognizes to correct mode sensor code, the shift is considered to have
been blocked. The blocked shift will increment the blocked shift counter by one. The TCCM
strategy for handling blocked shifts will be described later. The process the TCCM performs for the
various shifts will be described first.
RANGE AND MODE SHIFTS
The process for performing all the range and mode shifts are the same. The following steps
describe the process.
- Allow time for Selector Switch debounce; 250 msec ± 50 msec.
- Extinguish the source gear's LED while flashing desired transfer case position's LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec per 'D' channel transition in the
destination gear's direction while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Solidly illuminate the selected gear's LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 seconds ± 100 msec. per 'D'
channel. The TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the
desired position.
The exception to the preceding sequence is when a shift from 4L to 2WD/AWD is requested. If
2WD/AWD is requested from the 4L position, the transfer case is first driven to the 4H position. If
the 4H position is reached, the transfer case is then driven back to the 2WD/AWD position and the
shift is considered complete. If the transfer case does not reach any the 4H position, but is in the
2WD/AWD 'D' channel, or the 2WD/AWD between gear position on the 4H side of 2WD/AWD, the
shift is also considered complete.
SHIFT OUT OF NEUTRAL
The following steps describe the process for a shift out of NEUTRAL.

Dodge Workshop Manuals > Transmission and Drivetrain > Transfer Case > Relays and Modules - Transfer Case > Control
Module, Transfer Case > Component Information > Locations > Page 4808
- Extinguish the Neutral LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec toward the transfer case 4H mode
position while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Extinguish the Neutral LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 ± seconds 100 msec. The
TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the desired position.
- When the Neutral button is released, if the 4H position is the desired position, the shift is
complete. Illuminate the 4H LED.
- Otherwise when the Neutral button is released, if all of the shift requirements are being met then
engage the shift motor towards the desired position for 1 second ± 100 msec per 'D' channel, (if
requirements for shifting are not met, illuminate the 4H LED and flash the destination LED as an
indication to the driver that all of the driver controllable shift conditions are not being met). If this
requires another range or mode shift, begin the range/mode shift process.
- If the desired mode sensor code is not received after the shift timer expires (i.e. a blocked or other
condition exists), refer to the Blocked Shift Strategy.
BLOCKED SHIFT STRATEGY
When a shift is commanded, the shift motor will be driven towards its destination position, except in
the case of shifting out of Neutral if 4L was selected (the transfer case will shift to the 4H position
first, before proceeding to 4L). If the shift is blocked on the way to the destination, the TCCM may
attempt to drive the motor back to the original position. This process will be allowed to occur 5
times. If the transfer case has reached a non-NEUTRAL 'D' channel during the shift re-attempts,
the LED for the achieved gear position is illuminated and the shift attempts are stopped. To
re-attempt the desired shift, the selector switch will need to be rotated to the current position until
the switch debounce timer expires then a shift will need to be requested again.
At the end of the 5th blocked attempt, the shift motor is driven towards the last known 'D' channel
position. If this motor drive allows the transfer case to reach the 2WD/AWD 'D' channel, or the
2WD/AWD between gear position on the 4H side of 2WD/AWD, the shift is considered complete
and the shift attempts are ended.
If the mode sensor is in the NEUTRAL region at the expiration of the shift timer, the TCCM will
continue to make the shift attempts according to the blocked shift strategy independent of whether
or not the driver controlled conditions are met.
For shifts from NEUTRAL, if all 5 attempts fail to reach the desired position (which by default is
4H), the motor will be driven to stall in the direction of 4H or 4L, depending on the achieved
position. If the transfer case has reached the 2WD/AWD or 4L between gear position nearest the
NEUTRAL positions and the shift conditions are no longer being met, the transfer case will be
driven toward the corresponding 'D' channel. Otherwise, the transfer case will be driven in the
direction opposite the last attempt with the desired target being 4H or 4L.
If the transfer case reaches the 2WD/AWD 'D' channel when being driven in the 4H direction, then
one final 1.0 second drive toward 4H is attempted. If the transfer case then reaches any of the 4H
positions, the shift is considered complete and the 4H LED is illuminated. If the transfer case is still
the 2WD/AWD position, the shift is considered complete and the 2WD/AWD LED is illuminated.
NOTE: If after the 5th blocked shift and reversal attempt, if the transfer case position is in the
NEUTRAL region, shift attempts will continue until a non-NEUTRAL 'D' channel is reached.
SHIFT REVERSAL TARGETS
If the shift timer expires (1 second per 'D' channel) and the transfer case has not reached the
desired position, all shifts will attempt to return to their original position with the exceptions of:
- If the intended shift is going to the High rail from Low and can't make it, but it can make the
2WD/AWD position, the motor stops at that position. The TCCM will not attempt to cross back over
NEUTRAL if it does not have to. This means that there was a block on the first attempt to go to 4H
and the transfer case has made it through NEUTRAL to a known good position, then the motor will
go back only to the 2WD/4WD position and execute the remainder of the attempts from there.
- For shifts out of NEUTRAL, any time a shift is commanded out of NEUTRAL, the system needs to
get out. The TCCM should never go to NEUTRAL unless the driver is commanding it and all
required conditions are being met
ENCODER DRIFT CORRECTION
Whenever a shift is completed, the TCCM stores the position in memory as the transfer case's
intended position. The TCCM continuously monitors the mode sensor and if the mode sensor drifts
toward into a NEUTRAL region sensor position for 2.0 seconds, the TCCM will perform a motor
drive to correct the drift. The transfer case will be driven toward the intended position for 1.0
seconds 100 msec. The TCCM will wait for 2.0 seconds ± 50 msec . and repeat the attempt to shift
to the desired position. This will continue until the intended position is reached.
SHIFT MOTOR BRAKING
Two modes of shift motor braking are employed to improve shift performance, static and dynamic.
Static shift motor braking is utilized under the
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Transmission and Drivetrain > Transfer Case > Relays and Modules - Transfer Case > Control
Module, Transfer Case > Component Information > Locations > Page 4809
following conditions:
- Whenever the transfer case is in the 2WD/AWD or 4L 'D' channel position.
- Whenever an invalid mode sensor code is present. Static motor braking is achieved by applying
+12V on both shift motor wires. NOTE: Static Shift Motor Braking is independent of ignition key
position.
SHIFT ATTEMPT LIMIT
To protect the transfer case system, the TCCM will impose a limit on the number of shifts that can
occur over a calibrated time period. The system will monitor the number of 'D' channel segment
transitions that occur in any 30 second time period. If the number of segment transitions is 30 or
greater, the system will go into a default mode. The default mode of operation for shifting is that the
number of allowed 'D' channel transitions permitted to occur will be 3 over each 15 second ± 100
msec calibrated window of time. After 5 minutes ± 100 msec, the motor can be assumed to have
cooled down and the system will revert to normal operation. The following rules also apply to the
shift limit:
- The attempt limit will not prevent shifts coming out of NEUTRAL, they will be allowed regardless
of the counter/timer.
- Any shift that is in progress when the counter reaches a maximum count in time will be allowed to
complete before the default mode is entered. D-channel transitions during this period will not be
counted towards the default mode limit.
- A block, regardless of the direction, whether towards destination or back towards reversal target
(shift timer expiring), will count as a value of 2 transitions towards the 30 segment transitions to go
into default mode as defined above. Current attempt limit values are 30 transitions in 30 seconds
and default mode values are 3 transitions every 15 seconds for 5 minutes.

SWITCH-SELECTOR
DESCRIPTION
The selector switch assembly (1) is mounted in the left side of the vehicle's Instrument Panel (IP)
and consists of a rotary knob connected to a resistive network for the mode and range shift
selections. Also located in this assembly is a recessed, normally open momentary switch for
making shifts into and out of transfer case NEUTRAL. A pen, or similar instrument, is used to make
a NEUTRAL shift selection, thus reducing the likelihood of an inadvertent shift request.
The selector switch also contains four light emitting diode's (LED's) to indicate the transfer case
position and whether a shift is in progress.
OPERATION
As the position of the selector switch varies, the resistance between the Mode Sensor supply
voltage pin and the Mode Sensor output will vary. Hardware, software, and calibrations within the
Transfer Case Control Module (TCCM) are provided that interpret the selector switch resistance as
given in the table below:
SELECTOR SWITCH INTERPRETATION
SELECTOR SWITCH INTERPRETATION
For resistances between the ranges B-E shown for each valid position (T-Case NEUTRAL, 4LO,
4HI, 2WD), the TCCM may interpret the resistance as: ^
either of the neighboring valid positions.
^ as an invalid fault position.
For resistances between the ranges E and F shown for 2WD and in-between positions, the TCCM
may interpret the resistance as: ^
the 2WD position.
^ an invalid fault position.
^ a valid in-between position.
For resistances between the ranges F and G shown for in-between positions and fault condition
(open), the TCCM may interpret the resistance as: ^
a valid in-between position.
^ an invalid fault position.

For resistances between the ranges A and B shown for the fault condition (short) and, T-Case
NEUTRAL, the TCCM may interpret the resistance as: ^
the T-Case NEUTRAL position.
^ an invalid fault position.
The LED's in the selector assembly are illuminated/flashed in the following manner to indicate a
particular condition or state. ^
A solidly illuminated LED indicates a successfully completed shift and the current operating mode
of the transfer case. While a shift has been requested but not yet completed, the LED for the
desired transfer case position is flashed.
^ A flashing operating mode LED for the desired gear indicates that a shift to that position has been
requested, but all of the driver controllable conditions have not been met. This is in an attempt to
notify the driver that the transmission needs to be put into NEUTRAL, the vehicle speed is too
great, or some other condition outlined (other than a diagnostic failure that would prevent this shift)
elsewhere is not met. Note that this flashing will continue indefinitely until the conditions are
eventually met, or the selector switch position is changed, or if diagnostic routines no longer allow
the requested shift.
^ If the driver attempts to make a shift into transfer case NEUTRAL, and any of the driver
controllable conditions are not met, the request will be ignored until all of the conditions are met or
until the NEUTRAL select button is released. Additionally the neutral lamp will flash, or begin to
flash while the button is depressed and operator controllable conditions are not being met. All of
the LED's except the Neutral will flash if any of the operator controllable conditions for shifting are
not met while the Neutral button is depressed. This "toggle" type of feature is necessary because
the TCCM would interpret another request immediately after the shift into transfer case NEUTRAL
has completed.
^ No LED's illuminated indicate a fault in the transfer case control system.

SENSOR-MODE
DESCRIPTION
The transfer case mode sensor (1) is an electronic device whose output can be interpreted to
indicate the shift motor shaft's rotary position. The sensor consists of a magnetic ring and four Hall
Effect Transistors to create a 4 channel digital device (non-contacting) whose output converts the
motor shaft position into a coded signal. The TCCM must supply 5VDC (+/- 0.5v) to the sensor and
monitor the shift motor position. The four channels are denoted A, B. C, and D. The sensor is
mechanically linked to the shaft of the cam which causes the transfer case shifting. The mode
sensor draws less than 53 mA.
OPERATION
During normal vehicle operation, the Transfer Case Control Module (TCCM) monitors the mode
sensor outputs at least every 250 (+/-50) milliseconds when the shift motor is stationary and 400
microseconds when the shift motor is active. A mode sensor signal between 3.8 Volts and 0.8 Volts
is considered to be undefined.
Refer to SECTOR ANGLES vs. TRANSFER CASE POSITION for the relative angles of the transfer
case shift sector versus the interpreted transfer case gear operating mode. Refer to MODE
SENSOR CHANNEL STATES for the sensor codes returned to the TCCM for each transfer case
mode sensor position. The various between gears positions can also be referred as the transfer
case's coarse position. These coarse positions come into play during shift attempts.

Description and Operation
Overdrive Solenoid: Description and Operation
ASSEMBLY-TRANSMISSION SOLENOID/TRS
DESCRIPTION
The transmission solenoid/TRS assembly is internal to the transmission and mounted on the valve
body assembly. The assembly consists of six solenoids that control hydraulic pressure to the six
friction elements (transmission clutches), and the torque converter clutch. The pressure control
solenoid is located on the side of the solenoid/TRS assembly. The solenoid/TRS assembly also
contains five pressure switches that feed information to the TCM.
OPERATION SOLENOIDS
Solenoids are used to control the L/R, 2C, 4C, OD, and UD friction elements. The reverse clutch is
controlled by line pressure and the position of the manual valve in the valve body. All the solenoids
are contained within the Solenoid and Pressure Switch Assembly. The solenoid and pressure
switch assembly contains one additional solenoid, Multi-Select (MS), which serves primarily to
provide 2nd and 3rd gear limp-in operation.
The solenoids receive electrical power from the Transmission Control Relay through a single wire.
The TCM energizes or operates the solenoids individually by grounding the return wire of the
solenoid as necessary. When a solenoid is energized, the solenoid valve shifts, and a fluid
passage is opened or closed (vented or applied), depending on its default operating state. The
result is an apply or release of a frictional element.
The MS and UD solenoids are normally applied to allow transmission limp-in in the event of an
electrical failure.
The continuity of the solenoids and circuits are periodically tested. Each solenoid is turned on or off
depending on its current state. An inductive spike should be detected by the TCM during this test. If
no spike is detected, the circuit is tested again to verify the failure. In addition to the periodic
testing, the solenoid circuits are tested if a speed ratio or pressure switch error occurs.
PRESSURE SWITCHES
The TCM relies on five pressure switches to monitor fluid pressure in the L/R, 2C, 4C, UD, and OD
hydraulic circuits. The primary purpose of these switches is to help the TCM detect when clutch
circuit hydraulic failures occur. The switches close at 23 psi and open at 11 psi, and simply indicate
whether or not pressure exists. The switches are continuously monitored by the TCM for the
correct states (open or closed) in each gear as shown in the following charts 45RFE PRESSURE
SWITCH STATES and 545RFE PRESSURE SWITCH STATES:

Description and Operation
Overdrive Indicator Lamp: Description and Operation
A tow/haul indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional overdrive automatic transmission, this indicator is electronically
disabled. The tow/haul indicator consists of the text "TOW/HAUL", which appears in the lower
portion of the odometer/trip odometer indicator Vacuum Fluorescent Display (VFD) unit.
The odometer/trip odometer VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial
face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "TOW/ HAUL" appears in an amber color and at the
same lighting level as the odometer/trip odometer information when it is illuminated by the
instrument cluster electronic circuit board. The tow/haul indicator is serviced as a unit with the VFD
in the instrument cluster.
The tow/haul indicator gives an indication to the vehicle operator when the Off position of the
tow/haul switch has been selected, disabling the electronically controlled overdrive feature of the
automatic transmission. This indicator is controlled by the instrument cluster circuit board based
upon cluster programming and electronic messages received by the cluster from the Powertrain
Control Module (PCM) over the Programmable Communications Interface (PCI) data bus.
The tow/haul indicator is completely controlled by the instrument cluster logic circuit, and that logic
will only allow this indicator to operate when the instrument cluster receives a battery current input
on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
tow/haul indicator for the following reasons:
- Tow/Haul Lamp-On Message - Each time the cluster receives a tow/haul lamp-on message from
the PCM indicating that the Off position of the tow/haul switch has been selected, the tow/haul
indicator will be illuminated. The indicator remains illuminated until the cluster receives a tow/haul
lamp-off message from the PCM, or until the ignition switch is turned to the Off position, whichever
occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the tow/haul indicator will be
turned on, then off again during the VFD portion of the test to confirm the functionality of the VFD
and the cluster control circuitry.
The PCM continually monitors the tow/haul switch to determine the proper outputs to the automatic
transmission. The PCM then sends the proper tow/haul lamp-on and lamp-off messages to the
instrument cluster.
For proper diagnosis of the overdrive control system, the PCM, the PCI data bus, or the electronic
message inputs to the instrument cluster that control the tow/haul indicator, a diagnostic scan tool
is required.

Shift Indicator: Description and Operation
An electronic automatic transmission gear selector indicator is standard factory-installed equipment
on this model. However, on vehicles not equipped with an optional automatic transmission, this
indicator is electronically disabled. The gear selector indicator information is displayed in an
electronic, blue-green Vacuum-Fluorescent Display (VFD) unit. The VFD unit is soldered onto the
cluster electronic circuit board and is visible through a window with a smoked clear lens located on
the lower edge of the speedometer gauge dial face of the cluster overlay. The dark lens over the
VFD prevents the indicator from being clearly visible when it is not illuminated.
The gear selector indicator VFD displays the following characters from left to right: "P," "R," "N,"
"D," "2," and "1". Respectively, these characters represent the park, reverse, neutral, drive, second
gear, and first gear positions of the transmission gear selector lever on the steering column. The
VFD illuminates a rectangular box around the character that represents the currently selected lever
position.
During daylight hours (exterior lamps Off) the gear selector VFD is illuminated at full brightness for
clear visibility. At night (exterior lamps are On), the VFD lighting level is adjusted with the other
cluster illumination lamps using the panel lamps dimmer thumbwheel on the headlamp switch.
However, a "Parade" mode position of the panel lamps dimmer thumbwheel allows the VFD to be
illuminated at full brightness if the exterior lamps are turned On during daylight hours. The gear
selector indicator VFD is serviced as a unit with the instrument cluster.
The electronic gear selector indicator gives an indication to the vehicle operator of the transmission
gear that has been selected with the automatic transmission gear selector lever. This indicator is
controlled by the instrument cluster circuit board based upon cluster programming. The cluster
circuitry automatically configures itself for the proper transmission and automatic transmission
model based upon the hard wired transmission range sensor mux circuit input to the cluster.
The gear selector indicator information is displayed by a dedicated Vacuum Fluorescent Display
(VFD) unit soldered onto the instrument cluster electronic circuit board, and the VFD will not display
the gear selector indicator information after the ignition switch is turned to the Off position. Each
time the cluster is disconnected from battery current for more than about five minutes, it must
configure itself for the automatic transmission model that is in the vehicle once it is reconnected to
battery current. The instrument cluster circuitry configures the gear selector indicator VFD based
upon the following inputs from the transmission range sensor:
- Open Circuit - If the cluster is configured for an automatic transmission and the transmission
range sensor mux circuit is open, the cluster circuitry controls the gear selector indicator display
based upon electronic messages received from the electronic Transmission Control Module ( TCM)
over the Programmable Communications Interface (PCI) data bus. If the transmission range sensor
mux circuit is open and no electronic messages are received from the TCM within two seconds, the
instrument cluster circuitry will not display any gear selector position until the condition is resolved
or until the ignition switch is turned to the Off position, whichever occurs first.
- Resolved Circuit - If the transmission range sensor mux circuit is resolved, the cluster circuitry
controls the gear selector indicator display based upon the resistance value of the hard wired input
from the transmission range sensor. If the cluster is configured for an automatic transmission with a
transmission range sensor input and detects a short to ground or an open in the transmission
range sensor mux input, the instrument cluster circuitry will not display any gear selector position in
the VFD. The VFD display for the short-to-ground and open circuit conditions will continue until the
condition is resolved or until the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gear selector indicator
VFD will display all of its characters at once during the VFD portion of the test to confirm the
functionality of the VFD and the cluster control circuitry.
On models with a TCM, the TCM continually monitors the transmission range sensor, then sends
the proper gear selector indicator position messages to the instrument cluster. On models without a
TCM, the instrument cluster continually monitors the hard wired transmission range sensor
multiplexed input.
On models with a TCM, for proper diagnosis of the transmission range sensor, the TCM, the PCI
data bus, or the electronic message inputs to the instrument cluster that control the gear selector
indicator, a diagnostic scan tool is required.

Temperature Warning Indicator - A/T: Description and Operation
A transmission over-temperature indicator is standard equipment on all instrument clusters.
However, on vehicles not equipped with an optional automatic transmission, this indicator is
electronically disabled. This indicator is located on the left side of the instrument cluster, to the left
of the fuel gauge.
The transmission over-temperature indicator consists of a stencil-like cutout of the text "TRANS
TEMP" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. A red Light Emitting
Diode (LED) behind the cutout in the opaque layer of the overlay causes the "TRANS TEMP" text
to appear in red through the translucent outer layer of the overlay when the indicator is illuminated
from behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The
transmission over-temperature indicator is serviced as a unit with the instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
transmission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus.
The transmission over-temperature indicator Light Emitting Diode (LED) is completely controlled by
the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the
instrument cluster receives a battery current input on the fused ignition switch output (run-start)
circuit. Therefore, the LED will always be off when the ignition switch is in any position except On
or Start. The LED only illuminates when it is provided a path to ground by the instrument cluster
transistor. The instrument cluster will turn on the transmission over-temperature indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-On Message - Each time the cluster receives a trans over-temp lamp-on
message from the PCM indicating that the transmission fluid temperature is 135° C (275° F) or
higher, the indicator will be illuminated and a single chime tone is sounded. The indicator remains
illuminated until the cluster receives a trans over-temp lamp-off message from the PCM, or until the
ignition switch is turned to the Off position, whichever occurs first. The chime tone feature will only
repeat during the same ignition cycle if the transmission over-temperature indicator is cycled off
and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the transmission
over-temperature indicator will be turned on, then off again during the bulb check portion of the test
to confirm the functionality of the LED and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition. The PCM then sends the proper trans over-temp lamp-on or lamp-off
messages to the instrument cluster. If the instrument cluster turns on the transmission
over-temperature indicator due to a high transmission oil temperature condition, it may indicate that
the transmission and/or the transmission cooling system are being overloaded or that they require
service. For further diagnosis of the transmission over-temperature indicator or the instrument
cluster circuitry that controls the LED.
For proper diagnosis of the transmission temperature sensor, the PCM, the PCI data bus, or the
electronic message inputs to the instrument cluster that control the transmission over-temperature
indicator, a diagnostic scan tool is required.

Four Wheel Drive Indicator Lamp: Description and Operation
A service 4WD indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional four-wheel drive system and electronically shifted transfer case, this
indicator is electronically disabled. The service 4WD indicator consists of the text "SERV 4WD",
which appears in the lower portion of the odometer/trip odometer Vacuum Fluorescent Display
(VFD) unit.
The odometer/trip odometer VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial
face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "SERV 4WD" appears in an amber color and at the same
lighting level as the odometer/trip odometer information when it is illuminated by the instrument
cluster electronic circuit board. The service 4WD indicator is serviced as a unit with the VFD in the
instrument cluster.
The service 4WD indicator gives an indication to the vehicle operator when the Transfer Case
Control Module (TCCM) has recorded a Diagnostic Trouble Code (DTC) for an electronic transfer
case circuit or component malfunction. This indicator is controlled by the instrument cluster circuit
board based upon cluster programming and electronic messages received by the cluster from the
TCCM over the Programmable Communications Interface (PCI) data bus.
The service 4WD indicator is completely controlled by the instrument cluster logic circuit, and that
logic will only allow this indicator to operate when the instrument cluster receives a battery current
input on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
service 4WD indicator for the following reasons:
- Service 4WD Lamp-On Message - Each time the cluster receives a service 4WD lamp-on
message from the TCCM, the indicator will be illuminated. The indicator remains illuminated until
the cluster receives a service 4WD lamp-off message from the TCCM, or until the ignition switch is
turned to the Off position, whichever occurs first.
- Communication Error - If the cluster receives no messages from the TCCM for five seconds, the
service 4WD indicator is illuminated by the instrument cluster to indicate a loss of TCCM
communication. The indicator remains controlled and illuminated by the cluster until a valid
message is received from the TCCM.
- Actuator Test - Each time the cluster is put through the actuator test, the service 4WD indicator
will be turned on, then off again during the VFD portion of the test to confirm the functionality of the
VFD and the cluster control circuitry.
The TCCM continually monitors the electronic transfer case switch and circuits to determine the
condition of the system. The TCCM then sends the proper lamp-on or lamp-off messages to the
instrument cluster.
For proper diagnosis of the TCCM, the PCI data bus, or the electronic message inputs to the
instrument cluster that control the service 4WD indicator, a diagnostic scan tool is required.

Operation
Control Module: Description and Operation
The Transmission Control Module (TCM) (2) may be sub-module within the Powertrain Control
Module (PCM) (3).
Or, for vehicles with a diesel engine, the Engine Control Module (ECM) (1). The PCM, and TCM
when equipped, is located at the right rear of the engine compartment, near the right inner fender.
The Transmission Control Module (TCM) controls all electronic operations of the transmission. The
TCM receives information regarding vehicle operation from both direct and indirect inputs, and
selects the operational mode of the transmission. Direct inputs are hard wired to, and used
specifically by the TCM. Indirect inputs are shared with the TCM via the vehicle communication
bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure

Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - A/T > Control Module, A/T > Component Information > Description and
Operation > Page 4924
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request Some examples of TCM indirect outputs are:
- Transmission Temperature (to PCM)
- PRNDL Position (to cluster/CCN) In addition to monitoring inputs and controlling outputs, the TCM
has other important responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed.
BATTERY FEED
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain memory in the TCM. When the battery (B+) is disconnected, this memory is
lost. When the battery (B+) is restored, this memory loss is detected by the TCM and a Diagnostic
Trouble Code (DTC) is set.
CLUTCH VOLUME INDEXES (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur.
Gear ratios can be determined by using the Scan Tool and reading the Input/Output Speed Sensor
values in the "Monitors" display Gear ratio can be obtained by dividing the Input Speed Sensor
value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1.

Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - A/T > Control Module, A/T > Component Information > Description and
Operation > Page 4925
In direct drive (3rd gear), the gear ratio changes to 1:1. The gear ratio changes as clutches are
applied and released. By monitoring the length of time it takes for the gear ratio to change following
a shift request, the TCM can determine the volume of fluid used to apply or release a friction
element.
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Certain mechanical problems within the input clutch assembly can cause inadequate or
out-of-range element volumes. Also, defective Input/Output Speed Sensors and wiring can cause
these conditions. The following chart identifies the appropriate clutch volumes and when they are
monitored/updated:
SHIFT SCHEDULES
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following:
- Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

As driving conditions change, the TCM appropriately adjusts the shift schedule. Refer to the chart
to determine the appropriate operation expected, depending on driving conditions.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - A/T > Transmission Control System Relay, A/T > Component
Information > Diagrams > Diagram Information and Instructions > Page 4932
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Transmission Control System Relay: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Transmission Control System Relay: Description and Operation Relay-Transmission Control
RELAY-TRANSMISSION CONTROL 45RFE/545RFE
DESCRIPTION
NOTE: The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power
to the solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off", no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Control Module: Description and Operation
The Transfer Case Control Module (TCCM) (2) is a microprocessor-based assembly, controlling
the 4X4 transfer case shift functions via the actuation of a shift motor and utilizing the feedback of a
mode sensor assembly. Communication is via the PCI serial bus. Inputs include user selectable
4X4 modes that include 2WD, AWD, 4HI, 4LO, and Neutral. The logic and driver circuitry is
contained in a molded plastic housing with an embedded heat-sink and is located behind the left
side of the lower instrument panel (1).
The Transfer Case Control Module (TCCM) utilizes the input from the transfer case mounted mode
sensor, the instrument panel mounted selector switch, and the following information from the
vehicle's PCI serial bus to determine if a shift is allowed.
- Engine RPM and Vehicle Speed
- Diagnostic Requests
- Manual Transmission and Brake Applied
- PRNDL
- Ignition Status
- ABS Messages
Once the TCCM determines that a requested shift is allowed, it actuates the bi-directional shift
motor as necessary to achieve the desired transfer case operating mode. The TCCM also monitors
the mode sensor while controlling the shift motor to determine the status of the shift attempt.
Several items can cause the requested shift not to be completed. If the TCCM has recognized a
fault (DTC) of some variety, it will begin operation in one of four Functionality Levels. These levels
are:
- Level Zero - Normal Operation.
- Level One - Only Mode Shifts Are Allowed.
- Level Two - Only Mode Shifts and Shifts Into LOW Are Allowed (No Neutral Shifts Are Allowed).
- Level Three - No Shifts Are Allowed
The TCCM can also be operating in one of three possible power modes. These power modes are:
- Full Power Mode is the normal operational mode of the module. This mode is achieved by normal
PCI bus traffic being present and the ignition being in the RUN position.
- Reduced Power Mode will be entered when the ignition has been powered off. In this state, the
module will shut down power supplied to external devices, and to electronic interface inputs and
outputs. From this state the module can enter either Sleep Mode or Full Power Mode. To enter this
mode, the module must receive an ignition message denoting that the ignition is off, or not receive
any messages for 5 ± 0.5 seconds. To exit this mode, the module must receive one ignition
message that denotes that the ignition is in the RUN position.
- Sleep Mode will be entered, from the Reduced Power Mode, when no PCI traffic has been
sensed for 20 ± 1 seconds. If during Sleep Mode the module detects PCI bus traffic, it will revert to
the Reduced Power mode while monitoring for ignition messages. It will remain in this state as long
as there is traffic other than run or start messages, and will return to Sleep mode if the bus goes
without traffic for 20 ± 1 seconds.
SHIFT REQUIREMENTS
If the TCCM is in full power mode and at functionality level zero, it uses the following criteria to
determine if a shift is allowed.
If any of the driver controllable conditions are not met once the shift request is recognized, the
TCCM will solidly illuminate the source position's LED and flash the desired position's LED for all
shifts except NEUTRAL. The NEUTRAL shift LED strategy will be discussed later.
Mode shifts will be allowed regardless of transmission gear or vehicle speed, whenever the
following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- A change in the Selector switch state indicates that a mode shift has been requested.
- A valid mode sensor signal is being sensed by the TCCM.

Information > Locations > Page 4964
- Proper transmit/receive messages are occurring on the PCI bus.
- Ignition key switch is in the RUN position.
Range shifts will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- A change in the Selector Switch state indicating a range shift has been requested.
- Transmission in NEUTRAL signal must be recognized for atleast 1.5 seconds ± 100 msec.
(Automatic transmissions only)
- Proper transmit/receive messages are occurring on the PCI bus.
- Clutch signal is recognized for 500 msec ± 50 msec (Manual transmissions only).
- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position.
- A valid mode sensor signal is being sensed by the TCCM.
A shift into transfer case Neutral will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- The recessed Neutral Selection switch has been depressed continuously for 4.0 seconds ± 100
msec while all shift conditions have been continuously met.
- Transmission in NEUTRAL signal recognized from the bus. (Automatic transmissions only)
- Clutch signal is recognized from the bus (Manual transmissions only).
- Proper message transmissions/receptions are occurring on the PCI bus.
- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position, engine off.
- Foot Brake is applied.
- A valid mode sensor signal is being sensed by the TCCM.
A shift out of transfer case Neutral will be allowed only if all of the following conditions are met:
- Front and rear wheel speed are within 21 km/hr (13 mph).
- The recessed Neutral Selection switch has been depressed continuously for 1.0 seconds ± 100
msec while all shift conditions have been continuously met.
- Transmission in NEUTRAL signal recognized from the bus.(Automatic transmissions only)
- Clutch signal is recognized from the bus (Manual transmissions only).
- Proper message transmissions/receptions are occurring on the PCI bus.
- Vehicle speed is less than or equal to 4.8 km/hr (3 miles per hour).
- Ignition key switch is in the RUN position.
- Foot Brake is applied.
- A valid mode sensor signal is being sensed by the TCCM.
SHIFT SEQUENCES
Once all the driver controllable conditions for the requested shift have been met, the TCCM begins
a shift timer with a maximum duration of 1 second per 'D' channel transition. If the shift timer
expires before the TCCM recognizes to correct mode sensor code, the shift is considered to have
been blocked. The blocked shift will increment the blocked shift counter by one. The TCCM
strategy for handling blocked shifts will be described later. The process the TCCM performs for the
various shifts will be described first.
RANGE AND MODE SHIFTS
The process for performing all the range and mode shifts are the same. The following steps
describe the process.
- Allow time for Selector Switch debounce; 250 msec ± 50 msec.
- Extinguish the source gear's LED while flashing desired transfer case position's LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec per 'D' channel transition in the
destination gear's direction while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Solidly illuminate the selected gear's LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 seconds ± 100 msec. per 'D'
channel. The TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the
desired position.
The exception to the preceding sequence is when a shift from 4L to 2WD/AWD is requested. If
2WD/AWD is requested from the 4L position, the transfer case is first driven to the 4H position. If
the 4H position is reached, the transfer case is then driven back to the 2WD/AWD position and the
shift is considered complete. If the transfer case does not reach any the 4H position, but is in the
2WD/AWD 'D' channel, or the 2WD/AWD between gear position on the 4H side of 2WD/AWD, the
shift is also considered complete.
SHIFT OUT OF NEUTRAL
The following steps describe the process for a shift out of NEUTRAL.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - Transfer Case > Control Module, Transfer Case > Component
Information > Locations > Page 4965
- Extinguish the Neutral LED.
- Engage the shift motor for a maximum of 1 second ± 100 msec toward the transfer case 4H mode
position while monitoring the mode sensor channel transitions.
- Disengage the shift motor when the correct mode sensor code is recognized.
- Extinguish the Neutral LED.
- Transmit a bus message that the transfer case shift is complete.
- If the desired mode sensor code is not received after the shift timer expires (ie. a blocked or other
condition exists), stop driving the motor and wait for 200 msec ± 50 msec. The shift motor is then
reversed in the direction back toward the source gear for up to 1.0 ± seconds 100 msec. The
TCCM waits for 2.0 seconds ± 50 msec. and repeats the attempt to shift to the desired position.
- When the Neutral button is released, if the 4H position is the desired position, the shift is
complete. Illuminate the 4H LED.
- Otherwise when the Neutral button is released, if all of the shift requirements are being met then
engage the shift motor towards the desired position for 1 second ± 100 msec per 'D' channel, (if
requirements for shifting are not met, illuminate the 4H LED and flash the destination LED as an
indication to the driver that all of the driver controllable shift conditions are not being met). If this
requires another range or mode shift, begin the range/mode shift process.
- If the desired mode sensor code is not received after the shift timer expires (i.e. a blocked or other
condition exists), refer to the Blocked Shift Strategy.
BLOCKED SHIFT STRATEGY
When a shift is commanded, the shift motor will be driven towards its destination position, except in
the case of shifting out of Neutral if 4L was selected (the transfer case will shift to the 4H position
first, before proceeding to 4L). If the shift is blocked on the way to the destination, the TCCM may
attempt to drive the motor back to the original position. This process will be allowed to occur 5
times. If the transfer case has reached a non-NEUTRAL 'D' channel during the shift re-attempts,
the LED for the achieved gear position is illuminated and the shift attempts are stopped. To
re-attempt the desired shift, the selector switch will need to be rotated to the current position until
the switch debounce timer expires then a shift will need to be requested again.
At the end of the 5th blocked attempt, the shift motor is driven towards the last known 'D' channel
position. If this motor drive allows the transfer case to reach the 2WD/AWD 'D' channel, or the
2WD/AWD between gear position on the 4H side of 2WD/AWD, the shift is considered complete
and the shift attempts are ended.
If the mode sensor is in the NEUTRAL region at the expiration of the shift timer, the TCCM will
continue to make the shift attempts according to the blocked shift strategy independent of whether
or not the driver controlled conditions are met.
For shifts from NEUTRAL, if all 5 attempts fail to reach the desired position (which by default is
4H), the motor will be driven to stall in the direction of 4H or 4L, depending on the achieved
position. If the transfer case has reached the 2WD/AWD or 4L between gear position nearest the
NEUTRAL positions and the shift conditions are no longer being met, the transfer case will be
driven toward the corresponding 'D' channel. Otherwise, the transfer case will be driven in the
direction opposite the last attempt with the desired target being 4H or 4L.
If the transfer case reaches the 2WD/AWD 'D' channel when being driven in the 4H direction, then
one final 1.0 second drive toward 4H is attempted. If the transfer case then reaches any of the 4H
positions, the shift is considered complete and the 4H LED is illuminated. If the transfer case is still
the 2WD/AWD position, the shift is considered complete and the 2WD/AWD LED is illuminated.
NOTE: If after the 5th blocked shift and reversal attempt, if the transfer case position is in the
NEUTRAL region, shift attempts will continue until a non-NEUTRAL 'D' channel is reached.
SHIFT REVERSAL TARGETS
If the shift timer expires (1 second per 'D' channel) and the transfer case has not reached the
desired position, all shifts will attempt to return to their original position with the exceptions of:
- If the intended shift is going to the High rail from Low and can't make it, but it can make the
2WD/AWD position, the motor stops at that position. The TCCM will not attempt to cross back over
NEUTRAL if it does not have to. This means that there was a block on the first attempt to go to 4H
and the transfer case has made it through NEUTRAL to a known good position, then the motor will
go back only to the 2WD/4WD position and execute the remainder of the attempts from there.
- For shifts out of NEUTRAL, any time a shift is commanded out of NEUTRAL, the system needs to
get out. The TCCM should never go to NEUTRAL unless the driver is commanding it and all
required conditions are being met
ENCODER DRIFT CORRECTION
Whenever a shift is completed, the TCCM stores the position in memory as the transfer case's
intended position. The TCCM continuously monitors the mode sensor and if the mode sensor drifts
toward into a NEUTRAL region sensor position for 2.0 seconds, the TCCM will perform a motor
drive to correct the drift. The transfer case will be driven toward the intended position for 1.0
seconds 100 msec. The TCCM will wait for 2.0 seconds ± 50 msec . and repeat the attempt to shift
to the desired position. This will continue until the intended position is reached.
SHIFT MOTOR BRAKING
Two modes of shift motor braking are employed to improve shift performance, static and dynamic.
Static shift motor braking is utilized under the
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - Transfer Case > Control Module, Transfer Case > Component
Information > Locations > Page 4966
following conditions:
- Whenever the transfer case is in the 2WD/AWD or 4L 'D' channel position.
- Whenever an invalid mode sensor code is present. Static motor braking is achieved by applying
+12V on both shift motor wires. NOTE: Static Shift Motor Braking is independent of ignition key
position.
SHIFT ATTEMPT LIMIT
To protect the transfer case system, the TCCM will impose a limit on the number of shifts that can
occur over a calibrated time period. The system will monitor the number of 'D' channel segment
transitions that occur in any 30 second time period. If the number of segment transitions is 30 or
greater, the system will go into a default mode. The default mode of operation for shifting is that the
number of allowed 'D' channel transitions permitted to occur will be 3 over each 15 second ± 100
msec calibrated window of time. After 5 minutes ± 100 msec, the motor can be assumed to have
cooled down and the system will revert to normal operation. The following rules also apply to the
shift limit:
- The attempt limit will not prevent shifts coming out of NEUTRAL, they will be allowed regardless
of the counter/timer.
- Any shift that is in progress when the counter reaches a maximum count in time will be allowed to
complete before the default mode is entered. D-channel transitions during this period will not be
counted towards the default mode limit.
- A block, regardless of the direction, whether towards destination or back towards reversal target
(shift timer expiring), will count as a value of 2 transitions towards the 30 segment transitions to go
into default mode as defined above. Current attempt limit values are 30 transitions in 30 seconds
and default mode values are 3 transitions every 15 seconds for 5 minutes.

Fluid Pressure Sensor/Switch: Description and Operation
SENSOR-LINE PRESSURE
DESCRIPTION
The TCM utilizes a closed-loop system to control transmission line pressure. The system contains
a variable force style solenoid, the Pressure Control Solenoid, mounted on the side of the solenoid
and pressure switch assembly. The solenoid is duty cycle controlled by the TCM to vent the
unnecessary line pressure supplied by the oil pump back to the sump. The system also contains a
variable pressure style sensor, the Line Pressure Sensor, which is a direct input to the TCM. The
line pressure solenoid monitors the transmission line pressure and completes the feedback loop to
the TCM. The TCM uses this information to adjust its control of the pressure control solenoid to
achieve the desired line pressure.
OPERATION
The TCM calculates the desired line pressure based upon inputs from the transmission and engine.
The TCM calculates the torque input to the transmission and uses that information as the primary
input to the calculation. The line pressure is set to a predetermined value during shifts and when
the transmission is in the PARK and NEUTRAL positions. This is done to ensure consistent shift
quality. During all other operation, the actual line pressure is compared to the desired line pressure
and adjustments are made to the pressure control solenoid duty cycle.

Overdrive Switch: Description and Operation
SWITCH-TOW/HAUL OVERDRIVE
DESCRIPTION
The tow/haul overdrive OFF (control) switch is located in the shift lever arm. The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the tow/haul overdrive
OFF mode to be entered and the Tow/Haul lamp to be illuminated. Pressing the switch a second
time causes normal overdrive operation to be restored and the tow/haul lamp to be turned off. The
tow/haul overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the tow/haul overdrive switch is turned to the OFF position, or when illuminated by the
transmission control module.

Transmission Position Switch/Sensor: Description and Operation
SENSOR-TRANSMISSION RANGE
DESCRIPTION
The Transmission Range Sensor (TRS) is part of the solenoid module, which is mounted to the top
of the valve body inside the transmission. The Transmission Range Sensor (TRS) has five switch
contact pins that: ^
Determine shift lever position
^ Supply ground to the Starter Relay in Park and Neutral only.
^ Supply +12 V to the backup lamps in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

SENSOR-INPUT SPEED
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following: ^
Transmission gear ratio
^ Speed ratio error detection
^ CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following: . Torque converter clutch slippage . Torque converter element speed ratio.

SENSOR-TRANSMISSION TEMPERATURE
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: ^
Battery (ambient) temperature
^ Engine coolant temperature
^ In-gear run time since start-up

SWITCH-SELECTOR
DESCRIPTION
The selector switch assembly (1) is mounted in the left side of the vehicle's Instrument Panel (IP)
and consists of a rotary knob connected to a resistive network for the mode and range shift
selections. Also located in this assembly is a recessed, normally open momentary switch for
making shifts into and out of transfer case NEUTRAL. A pen, or similar instrument, is used to make
a NEUTRAL shift selection, thus reducing the likelihood of an inadvertent shift request.
The selector switch also contains four light emitting diode's (LED's) to indicate the transfer case
position and whether a shift is in progress.
OPERATION
As the position of the selector switch varies, the resistance between the Mode Sensor supply
voltage pin and the Mode Sensor output will vary. Hardware, software, and calibrations within the
Transfer Case Control Module (TCCM) are provided that interpret the selector switch resistance as
given in the table below:
SELECTOR SWITCH INTERPRETATION
SELECTOR SWITCH INTERPRETATION
For resistances between the ranges B-E shown for each valid position (T-Case NEUTRAL, 4LO,
4HI, 2WD), the TCCM may interpret the resistance as: ^
either of the neighboring valid positions.
^ as an invalid fault position.
For resistances between the ranges E and F shown for 2WD and in-between positions, the TCCM
may interpret the resistance as: ^
the 2WD position.
^ an invalid fault position.
^ a valid in-between position.
For resistances between the ranges F and G shown for in-between positions and fault condition
(open), the TCCM may interpret the resistance as: ^

requested, but all of the driver controllable conditions have not been met. This is in an attempt to
notify the driver that the transmission needs to be put into NEUTRAL, the vehicle speed is too
great, or some other condition outlined (other than a diagnostic failure that would prevent this shift)
elsewhere is not met. Note that this flashing will continue indefinitely until the conditions are
eventually met, or the selector switch position is changed, or if diagnostic routines no longer allow
the requested shift.
^ If the driver attempts to make a shift into transfer case NEUTRAL, and any of the driver
controllable conditions are not met, the request will be ignored until all of the conditions are met or
until the NEUTRAL select button is released. Additionally the neutral lamp will flash, or begin to
flash while the button is depressed and operator controllable conditions are not being met. All of
the LED's except the Neutral will flash if any of the operator controllable conditions for shifting are
not met while the Neutral button is depressed. This "toggle" type of feature is necessary because
the TCCM would interpret another request immediately after the shift into transfer case NEUTRAL
has completed.
^ No LED's illuminated indicate a fault in the transfer case control system.

Sensor-Mode
SENSOR-MODE
DESCRIPTION
The transfer case mode sensor (1) is an electronic device whose output can be interpreted to
indicate the shift motor shaft's rotary position. The sensor consists of a magnetic ring and four Hall
Effect Transistors to create a 4 channel digital device (non-contacting) whose output converts the
motor shaft position into a coded signal. The TCCM must supply 5VDC (+/- 0.5v) to the sensor and
monitor the shift motor position. The four channels are denoted A, B. C, and D. The sensor is
mechanically linked to the shaft of the cam which causes the transfer case shifting. The mode
sensor draws less than 53 mA.
OPERATION
During normal vehicle operation, the Transfer Case Control Module (TCCM) monitors the mode
sensor outputs at least every 250 (+/-50) milliseconds when the shift motor is stationary and 400
microseconds when the shift motor is active. A mode sensor signal between 3.8 Volts and 0.8 Volts
is considered to be undefined.

SENSOR-MODE
DESCRIPTION
The transfer case mode sensor is an electronic device whose output can be interpreted to indicate
the shift motor shaft's rotary position. The sensor consists of a magnetic ring and four Hall Effect
Transistors to create a 4 channel digital device (non-contacting) whose output converts the motor
shaft position into a coded signal. The TCCM must supply 5VDC (+/0.5v) to the sensor and monitor
the shift motor position. The four channels are denoted A, B. C, and D. The sensor is mechanically
linked to the shaft of the cam which causes the transfer case shifting. The mode sensor draws less
than 53 mA.
OPERATION
During normal vehicle operation, the Transfer Case Control Module (TCCM) monitors the mode
sensor outputs at least every 250 (+/-50) milliseconds when the shift motor is stationary and 400
microseconds when the shift motor is active. A mode sensor signal between 3.8 Volts and 0.8 Volts
is considered to be undefined. Refer to SECTOR ANGLES vs. TRANSFER CASE POSITION for
the relative angles of the transfer case shift sector versus the interpreted transfer case gear
operating mode. Refer to MODE SENSOR CHANNEL STATES for the sensor codes returned to
the TCCM for each transfer case mode sensor position. The various between gears positions can
also be referred as the transfer case's coarse position. These coarse positions come into play
during shift attempts.

Component Information > Description and Operation
ABS Light: Description and Operation
An Antilock Brake System (ABS) indicator is standard equipment on all instrument clusters.
However, the instrument cluster can be programmed to disable this indicator on vehicles that are
not equipped with the ABS or Rear Wheel Anti-Lock (RWAL) brake systems, which are not
available in some markets. On vehicles equipped with a gasoline engine, the ABS indicator is
located near the lower edge of the instrument cluster, between the tachometer and the
speedometer. On vehicles equipped with a diesel engine, the ABS indicator is located on the right
side of the instrument cluster, to the right of the engine temperature gauge.
The ABS indicator consists of a stencil-like cutout of the International Control and Display Symbol
icon for "Failure of Anti-lock Braking System" in the opaque layer of the instrument cluster overlay.
The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not
illuminated. An amber Light Emitting Diode (LED) behind the cutout in the opaque layer of the
overlay causes the icon to appear in amber through the translucent outer layer of the overlay when
the indicator is illuminated from behind by the LED, which is soldered onto the instrument cluster
electronic circuit board. The ABS indicator is serviced as a unit with the instrument cluster.
The ABS indicator gives an indication to the vehicle operator when the ABS system is faulty or
inoperative. This indicator is controlled by a transistor on the instrument cluster circuit board based
upon cluster programming and electronic messages received by the cluster from the Controller
Antilock Brake (CAB) over the Programmable Communications Interface (PCI) data bus.
The ABS indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster
logic circuit, and that logic will only allow this indicator to operate when the instrument cluster
receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the
LED will always be off when the ignition switch is in any position except On or Start. The LED only
illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument
cluster will turn on the ABS indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the ABS indicator is
illuminated for about four seconds as a bulb test. The entire bulb test is a function of the CAB.
- ABS Lamp-On Message - Each time the cluster receives a lamp-on message from the CAB, the
ABS indicator will be illuminated. The indicator remains illuminated until the cluster receives a
lamp-off message from the CAB, or until the ignition switch is turned to the Off position, whichever
occurs first.
- Communication Error - If the cluster receives no lamp-on or lamp-off messages from the CAB for
five consecutive message cycles, the ABS indicator is illuminated. The indicator remains
illuminated until the cluster receives a valid message from the CAB, or until the ignition switch is
turned to the Off position, whichever occurs first.
- Actuator Test - Each time the instrument cluster is put through the actuator test, the ABS indicator
will be turned on, then off again during the bulb check portion of the test to confirm the functionality
of the LED and the cluster control circuitry.
- ABS Diagnostic Test - The ABS indicator is blinked on and off by lamp-on and lamp-off messages
from the CAB during the performance of the ABS diagnostic tests.
The CAB continually monitors the ABS circuits and sensors to decide whether the system is in
good operating condition. The CAB then sends the proper lamp-on or lamp-off messages to the
instrument cluster. If the CAB sends a lamp-on message after the bulb test, it indicates that the
CAB has detected a system malfunction and/or that the ABS system has become inoperative. The
CAB will store a Diagnostic Trouble Code (DTC) for any malfunction it detects. Each time the ABS
indicator fails to light due to an open or short in the cluster ABS indicator circuit, the cluster sends a
message notifying the CAB of the condition, then the instrument cluster and the CAB will each
store a DTC.
For proper diagnosis of the antilock brake system, the CAB, the PCI data bus, or the electronic
message inputs to the instrument cluster that control the ABS indicator, a diagnostic scan tool is
required.

Electronic Brake Control Module: Description and Operation
The Antilock Brake Module (ABM) is mounted to the Hydraulic Control Unit (HCU) and operates the
ABS system.
The ABM voltage source is through the ignition switch in the RUN position. The ABM contains a
self check program that illuminates the ABS warning light when a system fault is detected. Faults
are stored in a diagnostic program memory and are accessible with the DRB III scan tool. ABS
faults remain in memory until cleared, or until after the vehicle is started approximately 50 times.
Stored faults are not erased if the battery is disconnected.
NOTE: If the ABM is being replaced with a new ABM is must be reprogrammed with the use of a
DRB III.

HCU (HYDRAULIC CONTROL UNIT)
DESCRIPTION
The HCU (1) consists of a valve body, pump motor, low pressure accumulators, inlet valves, outlet
valves and noise attenuators.
OPERATION
Accumulators in the valve body store extra fluid released to the system for ABS mode operation.
The pump provides the fluid volume needed and is operated by a DC type motor. The motor is
controlled by the CAB.
The valves modulate brake pressure during antilock braking and are controlled by the CAB.
The HCU provides three channel pressure control to the front and rear brakes. One channel
controls the rear wheel brakes in tandem. The two remaining channels control the front wheel
brakes individually.
During antilock braking, the solenoid valves are opened and closed as needed.
During normal braking, the HCU solenoid valves and pump are not activated. The master cylinder
and power booster operate the same as a vehicle without an ABS brake system.
NOTE: The three modes mentioned below do occur but not necessarily in the order listed every
time.
During antilock braking, solenoid valve pressure modulation occurs in three stages, pressure
increase, pressure hold, and pressure decrease. The valves are all contained in the valve body
portion of the HCU.
PRESSURE DECREASE
The outlet valve is opened and the inlet valve is closed during the pressure decrease cycle.
A pressure decrease cycle is initiated when speed sensor signals indicate high wheel slip at one or
more wheels. At this point, the CAB closes the inlet then opens the outlet valve, which also opens
the return circuit to the accumulators. Fluid pressure is allowed to bleed off (decrease) as needed
to prevent wheel lock.
Once the period of high wheel slip has ended, the CAB closes the outlet valve and begins a
pressure increase or hold cycle as needed.
PRESSURE HOLD
Both solenoid valves are closed in the pressure hold cycle but only the inlet valve is energized.
Fluid apply pressure in the control channel is maintained at a constant rate. The CAB maintains the
hold cycle until sensor inputs indicate a pressure change is necessary.
PRESSURE INCREASE
The inlet valve is open and the outlet valve is closed during the pressure increase cycle. The
pressure increase cycle is used to reapply the brakes. This cycle controls re-application of fluid
apply pressure.

Wheel Speed Sensor: Description and Operation
SENSOR- WHEEL SPEED-ABS-FRONT
DESCRIPTION
The ABS brake system uses 3 wheel speed sensors. A sensor is mounted to each front
hub/bearings. The third sensor is mounted on top of the rear axle differential housing.
OPERATION
The Wheel Speed Sensor consists of a magnet (1) surrounded by windings from a single strand of
wire (5). The sensor sends a small AC signal to the ABM. This signal is generated by magnetic
induction. The magnetic induction is created when a toothed sensor ring (exciter ring or tone
wheel) (4) passes the stationary magnetic WSS.
When the ring gear is rotated, the exciter ring (4) passes the tip of the WSS. As the exciter ring
tooth approaches the tip of the WSS, the magnetic lines of force expand, causing the magnetic
field to cut across the sensor's windings (5). This, in turn causes current to flow through the WSS
circuit in one direction. When the exciter ring tooth moves away from the sensor tip, the magnetic
lines of force collapse cutting the winding in the opposite direction. This causes the current to flow
in the opposite direction. Every time a tooth of the exciter ring passes the tip of the WSS, an AC
signal is generated current. Each AC signal (positive to negative signal or squarewave) is
interpreted by the ABM. It then compares the frequency of the sinewave to a time value to calculate
vehicle speed. The ABM continues to monitor the frequency to determine a deceleration rate that
would indicate a possible wheel-locking tendency.
The signal strength of any magnetic induction sensor is directly affected by: ^
Magnetic field strength; the stronger the magnetic field, the stronger the signal
^ Number of windings in the sensor; more windings provide a stronger signal
^ Exciter ring speed; the faster the exciter ring/tone wheel rotates, the stronger the signal will be
^ Distance (3) "air gap" between the exciter ring teeth and WSS; the closer the WSS is to the
exciter ring/tone wheel, the stronger the signal will be.
The WSS is not adjustable. A clearance specification has been established for manufacturing
tolerances. If the clearance is not within these specifications, then either the WSS or other
components may be damaged. The clearance between the WSS and the exciter ring is 0.005 0.050 inch.
The assembly plant performs a "Rolls Test" on every vehicle that leaves the assembly plant. One
of the test performed is a test of the WSS. To properly test the sensor, the assembly plant connects
test equipment to the Data Link Connector (DLC). This connector is located to the right of the
steering column and attached to the lower portion of the instrument panel. The rolls test terminal is
spliced to the WSS circuit. The vehicle is then driven on a set of rollers and the WSS output is
monitored for proper operation.

tank manufacturers pressure recommendations. Generally, a tank pressure of 15 - 20 psi is
sufficient for bleeding.
Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding.
Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to
leakage, or drawing air back into the system.

Brake Bleeding: Service and Repair Antilock Brake System
STANDARD PROCEDURE
ABS BRAKE BLEEDING
ABS system bleeding requires conventional bleeding methods plus use of the DRB scan tool. The
procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and
bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to
remove any air remaining in the system. 1. Perform base brake bleeding. 2. Connect scan tool to
the Data Link Connector. 3. Select ANTILOCK BRAKES, followed by MISCELLANEOUS, then
ABS BRAKES. Follow the instructions displayed. When scan tool displays
TEST COMPLETE, disconnect scan tool and proceed.
4. Perform base brake bleeding a second time. 5. Top off master cylinder fluid level and verify
proper brake operation before moving vehicle.

CALIPERS-DISC BRAKE
DESCRIPTION
LIGHT DUTY (LD) CALIPERS
The calipers are a single piston type in the rear and dual piston type in the front. The calipers are
free to slide laterally, this allows continuous compensation for lining wear.
OPERATION
When the brakes are applied fluid pressure is exerted against the caliper piston (2). The fluid
pressure is exerted equally and in all directions. This means pressure exerted against the caliper
piston and within the caliper bore will be equal.
Fluid pressure applied to the piston is transmitted directly to the inboard brake pad (5). This forces
the pad lining against the inner surface of the disc brake rotor. At the same time, fluid pressure
within the piston bore forces the caliper to slide inward on the mounting bolts. This action brings the
outboard brake pad lining (6) into contact with the outer surface of the disc brake rotor.
In summary, fluid pressure acting simultaneously on both piston and caliper, produces a strong
clamping action. When sufficient force is applied. friction will attempt to stop the rotors from turning
and bring the vehicle to a stop.
Application and release of the brake pedal generates only a very slight movement of the caliper
and piston. Upon release of the pedal, the caliper and piston return to a rest position. The brake
pads do not retract an appreciable distance from the rotor. In fact, clearance is usually at, or close
to zero. The reasons for this are to keep road debris from getting between the rotor and lining and
in wiping the rotor surface clear each revolution.
The caliper piston seal (4) controls the amount of piston (2) extension needed to compensate for
normal lining wear.
During brake application, the seal is deflected outward by fluid pressure and piston movement (6).
When the brakes (and fluid pressure) are released, the seal relaxes and retracts the piston (3).
The amount of piston retraction is determined by the amount of seal deflection. Generally the
amount is just enough to maintain contact between the piston and inboard brake pad.

Brake Rotor/Disc: Testing and Inspection
ROTORS
DIAGNOSIS AND TESTING
DISC BRAKE ROTOR
The rotor braking surfaces should not be refinished unless necessary. Light surface rust and scale
can be removed with a lathe equipped with dual sanding discs. The rotor surfaces can be restored
by machining with a disc brake lathe if surface scoring and wear are light. Replace the rotor for the
following conditions: ^
Severely Scored
^ Tapered
^ Hard Spots
^ Cracked
^ Below Minimum Thickness
ROTOR MINIMUM THICKNESS
Measure rotor thickness at the center of the brake shoe contact surface. Replace the rotor if below
minimum thickness, or if machining would reduce thickness below the allowable minimum.
Rotor minimum thickness is usually specified on the rotor hub. The specification is either stamped
or cast into the hub surface.
ROTOR RUNOUT
Check rotor lateral runout with dial indicator C-3339 (1). Excessive lateral runout will cause brake
pedal pulsation and rapid, uneven wear of the brake shoes. Position the dial indicator plunger
approximately 25.4 mm (1 inch) inward from the rotor edge.
NOTE: Be sure wheel bearing has zero end play before checking rotor runout.
Maximum allowable rotor runout is 0.131 mm (0.005 inch) HD. Maximum allowable rotor runout is
0.050 mm (0.002 inch) LD.
ROTOR THICKNESS VARIATION
Variations in rotor thickness will cause pedal pulsation, noise and shudder.
Measure rotor thickness at 6 to 12 points around the rotor face.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component
Information > Specifications > Page 5111
Position the micrometer (1) approximately 25.4 mm (1 inch) from the rotor (2) outer circumference
for each measurement.
Thickness should not vary by more than 0.015 mm (0.0059 inch) from point-to-point on the rotor.
Machine or replace the rotor if necessary.

Brake Bleeding: Service and Repair Base Brake System
STANDARD PROCEDURE
MANUAL BLEEDING
Use Mopar(R) brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3
standards only. Use fresh, clean fluid from a sealed container at all times. 1. Remove reservoir filler
caps and fill reservoir. 2. If calipers were overhauled, open all caliper bleed screws. Then close
each bleed screw as fluid starts to drip from it. Top off master cylinder
reservoir once more before proceeding.
3. Attach one end of bleed hose (1) to bleed screw and insert opposite end in glass container (2)
partially filled with brake fluid. Be sure end of bleed
hose is immersed in fluid.
NOTE: Bleed procedure should be in this order (1) Right rear (2) Left rear (3) Right front (4) Left
front.
4. Open up bleeder, then have a helper press down the brake pedal. Once the pedal is down close
the bleeder. Repeat bleeding until fluid stream is
clear and free of bubbles. Then move to the next wheel.
5. Before moving the vehicle verify the pedal is firm and not mushy. 6. Top off the brake fluid and
install the reservoir cap.
PRESSURE BLEEDING
Use Mopar(R) brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3
standards only. Use fresh, clean fluid from a sealed container at all times.
Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the
tank manufacturers pressure recommendations. Generally, a tank pressure of 15 - 20 psi is
sufficient for bleeding.
Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding.
Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to
leakage, or drawing air back into the system.

CALIPERS-DISC BRAKE
DESCRIPTION
LIGHT DUTY (LD) CALIPERS
The calipers are a single piston type in the rear and dual piston type in the front. The calipers are
free to slide laterally, this allows continuous compensation for lining wear.
OPERATION
When the brakes are applied fluid pressure is exerted against the caliper piston (2). The fluid
pressure is exerted equally and in all directions. This means pressure exerted against the caliper
piston and within the caliper bore will be equal.
Fluid pressure applied to the piston is transmitted directly to the inboard brake pad (5). This forces
the pad lining against the inner surface of the disc brake rotor. At the same time, fluid pressure
within the piston bore forces the caliper to slide inward on the mounting bolts. This action brings the
outboard brake pad lining (6) into contact with the outer surface of the disc brake rotor.
In summary, fluid pressure acting simultaneously on both piston and caliper, produces a strong
clamping action. When sufficient force is applied. friction will attempt to stop the rotors from turning
and bring the vehicle to a stop.
Application and release of the brake pedal generates only a very slight movement of the caliper
and piston. Upon release of the pedal, the caliper and piston return to a rest position. The brake
pads do not retract an appreciable distance from the rotor. In fact, clearance is usually at, or close
to zero. The reasons for this are to keep road debris from getting between the rotor and lining and
in wiping the rotor surface clear each revolution.
The caliper piston seal (4) controls the amount of piston (2) extension needed to compensate for
normal lining wear.
During brake application, the seal is deflected outward by fluid pressure and piston movement (6).
When the brakes (and fluid pressure) are released, the seal relaxes and retracts the piston (3).
The amount of piston retraction is determined by the amount of seal deflection. Generally the
amount is just enough to maintain contact between the piston and inboard brake pad.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

Brake Fluid: Testing and Inspection
FLUID DIAGNOSIS AND TESTING
BRAKE FLUID CONTAMINATION
Indications of fluid contamination are swollen or deteriorated rubber parts.
Swollen rubber parts indicate the presence of petroleum in the brake fluid.
To test for contamination, put a small amount of drained brake fluid in clear glass jar. If fluid
separates into layers, there is mineral oil or other fluid contamination of the brake fluid.
If brake fluid is contaminated, drain and thoroughly flush system. Replace master cylinder,
proportioning valve, caliper seals, wheel cylinder seals, Antilock Brakes hydraulic unit and all
hydraulic fluid hoses.

Brake Proportioning/Combination Valve: Description and Operation
HYDRAULIC/MECHANICAL
DESCRIPTION - ELECTRONIC VARIABLE BRAKE PROPORTIONING
Vehicles equipped with ABS use Electronic Variable Brake Proportioning (EVBP) to balance
front-to-rear braking. The EVBP is used in place of a rear proportioning valve. The EVBP system
uses the ABS system to control the slip of the rear wheels in partial braking range. The braking
force of the rear wheels is controlled electronically by using the inlet and outlet valves located in the
Integrated Control Unit (ICU).
OPERATION - ELECTRONIC VARIABLE BRAKE PROPORTIONING
EVBP is able to decrease, hold and increase rear brake pressure without activating full ABS
control. Upon entry into EVBP the inlet valve for the rear brake circuit is switched on so that the
fluid supply from the master cylinder is shut off. In order to decrease the rear brake pressure, the
outlet valve for the rear brake circuit is pulsed. This allows fluid to enter the Low Pressure
Accumulator (LPA) in the Hydraulic Control Unit (HCU) resulting in a drop in fluid pressure to the
rear brakes. In order to increase the rear brake pressure, the outlet valve is switched off and the
inlet valve is pulsed. This increases the pressure to the rear brakes.
The EVBP will remain functional during many ABS fault modes. If both the red BRAKE and amber
ABS warning indicators are illuminated, the EVBP may not be functioning.

Hydraulic Control Assembly - Antilock Brakes: Description and Operation
HCU (HYDRAULIC CONTROL UNIT)
DESCRIPTION
The HCU (1) consists of a valve body, pump motor, low pressure accumulators, inlet valves, outlet
valves and noise attenuators.
OPERATION
Accumulators in the valve body store extra fluid released to the system for ABS mode operation.
The pump provides the fluid volume needed and is operated by a DC type motor. The motor is
controlled by the CAB.
The valves modulate brake pressure during antilock braking and are controlled by the CAB.
The HCU provides three channel pressure control to the front and rear brakes. One channel
controls the rear wheel brakes in tandem. The two remaining channels control the front wheel
brakes individually.
During antilock braking, the solenoid valves are opened and closed as needed.
During normal braking, the HCU solenoid valves and pump are not activated. The master cylinder
and power booster operate the same as a vehicle without an ABS brake system.
NOTE: The three modes mentioned below do occur but not necessarily in the order listed every
time.
During antilock braking, solenoid valve pressure modulation occurs in three stages, pressure
increase, pressure hold, and pressure decrease. The valves are all contained in the valve body
portion of the HCU.
PRESSURE DECREASE
The outlet valve is opened and the inlet valve is closed during the pressure decrease cycle.
A pressure decrease cycle is initiated when speed sensor signals indicate high wheel slip at one or
more wheels. At this point, the CAB closes the inlet then opens the outlet valve, which also opens
the return circuit to the accumulators. Fluid pressure is allowed to bleed off (decrease) as needed
to prevent wheel lock.
Once the period of high wheel slip has ended, the CAB closes the outlet valve and begins a
pressure increase or hold cycle as needed.
PRESSURE HOLD
Both solenoid valves are closed in the pressure hold cycle but only the inlet valve is energized.
Fluid apply pressure in the control channel is maintained at a constant rate. The CAB maintains the
hold cycle until sensor inputs indicate a pressure change is necessary.
PRESSURE INCREASE
The inlet valve is open and the outlet valve is closed during the pressure increase cycle. The
pressure increase cycle is used to reapply the brakes. This cycle controls re-application of fluid
apply pressure.

Brake Master Cylinder: Description and Operation
MASTER CYLINDER
DESCRIPTION
A two-piece master cylinder is used on all models. The cylinder body containing the primary and
secondary pistons is made of aluminum. The removable fluid reservoir is made of nylon reinforced
with glass fiber. The reservoir stores reserve brake fluid for the hydraulic brake circuits and has a
switch for indicating low fluid levels. The reservoir is the only serviceable component.
The fluid compartments of the nylon reservoir are interconnected to permit fluid level equalization.
However, the equalization feature does not affect circuit separation in the event of a front or rear
brake malfunction. The reservoir compartments will retain enough fluid to operate the functioning
hydraulic circuit.
Care must be exercised when removing/installing the master cylinder connecting lines. The threads
in the cylinder fluid ports can be damaged if care is not exercised. Start all brake line fittings by
hand to avoid cross threading.
The cylinder reservoir can be replaced when necessary. However, the aluminum body section of
the master cylinder is not a repairable component.
NOTE: If diagnosis indicates that an internal malfunction has occurred, the aluminum body section
must be replaced as an assembly.
OPERATION
The master cylinder bore contains a primary and secondary piston. The primary piston supplies
hydraulic pressure to the front brakes. The secondary piston supplies hydraulic pressure to the rear
brakes.

Brake Master Cylinder: Testing and Inspection
DIAGNOSIS AND TESTING
MASTER CYLINDER/POWER BOOSTER
1. Start engine and check booster vacuum hose connections. A hissing noise indicates vacuum
leak. Correct any vacuum leak before proceeding. 2. Stop engine and shift transmission into
Neutral. 3. Pump brake pedal until all vacuum reserve in booster is depleted. 4. Press and hold
brake pedal under light foot pressure. The pedal should hold firm, if the pedal falls away master
cylinder is faulty (internal
leakage).
5. Start engine and note pedal action. It should fall away slightly under light foot pressure then hold
firm. If no pedal action is discernible, power
booster, vacuum supply, or vacuum check valve is faulty. Proceed to the POWER BOOSTER
VACUUM TEST.
6. If the POWER BOOSTER VACUUM TEST passes, rebuild booster vacuum reserve as follows:
Release brake pedal. Increase engine speed to
1500 rpm, close the throttle and immediately turn off ignition to stop engine.
7. Wait a minimum of 90 seconds and try brake action again. Booster should provide two or more
vacuum assisted pedal applications. If vacuum
assist is not provided, booster is faulty.
POWER BOOSTER VACUUM TEST
1. Connect vacuum gauge (6) to booster check valve (4) with short length of hose (3) and T-fitting
(2). 2. Start and run engine at curb idle speed for one minute. 3. Observe the vacuum supply. If
vacuum supply is not adequate, repair vacuum supply. 4. Clamp (1) hose (7) shut between intake
vacuum source (5) and check valve (4). 5. Stop engine and observe vacuum gauge (6). 6. If
vacuum drops more than one inch HG (33 millibars) within 15 seconds, booster diaphragm or
check valve is faulty.
POWER BOOSTER CHECK VALVE TEST
1. Disconnect vacuum hose from check valve (1). 2. Remove check valve (1) and valve seal (2)
from booster (3). 3. Use a hand operated vacuum pump for test. 4. Apply 15 - 20 inches vacuum at
large end of check valve. 5. Plug off the small end to prevent vacuum leakage. 6. Vacuum should
hold steady. If gauge on pump indicates vacuum loss, check valve is faulty and should be replaced.

Component Information > Description and Operation
Parking Brake Warning Lamp: Description and Operation
A brake indicator is standard equipment on all instrument clusters. This indicator is located near the
lower edge of the instrument cluster, between the tachometer and the speedometer.
The brake indicator consists of a stencil-like cutout of the word "BRAKE" and the International
Control and Display Symbol icon for "Brake Failure" in the opaque layer of the instrument cluster
overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it
is not illuminated. A red Light Emitting Diode (LED) behind the cutout in the opaque layer of the
overlay causes the "BRAKE" text and icon to appear in red through the translucent outer layer of
the overlay when the indicator is illuminated from behind by the LED, which is soldered onto the
instrument cluster electronic circuit board. The brake indicator is serviced as a unit with the
instrument cluster.
The brake indicator gives an indication to the vehicle operator when the parking brake is applied,
when there are certain brake hydraulic system malfunctions as indicated by a low brake hydraulic
fluid level condition, or when the brake fluid level switch is disconnected. The brake indicator can
also give an indication when certain faults are detected in the Antilock Brake System (ABS). This
indicator is controlled by a transistor on the instrument cluster circuit board based upon cluster
programming, electronic messages received by the cluster from the Controller Antilock Brake
(CAB) over the Programmable Communications Interface (PCI) data bus, and a hard wired input
from the park brake switch.
The brake indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster
logic circuit, and that logic will only allow this indicator to operate when the instrument cluster
receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the
LED will always be off when the ignition switch is in any position except On or Start. The LED only
illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument
cluster will turn on the brake indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the brake indicator is
illuminated by the instrument cluster for about two seconds as a bulb test.
- Brake Lamp-On Message - Each time the cluster receives a lamp-on message from the CAB, the
brake indicator will be illuminated. The CAB can also send brake lamp-on messages as feedback
during ABS diagnostic procedures. The indicator remains illuminated until the cluster receives a
lamp-off message from the CAB, or until the ignition switch is turned to the Off position, whichever
occurs first.
- Park Brake Switch Input - Each time the cluster detects ground on the park brake switch sense
circuit (park brake switch closed = park brake applied or not fully released) while the ignition switch
is in the On position, the brake indicator flashes on and off. The indicator continues to flash until the
park brake switch sense input to the cluster is an open circuit (park brake switch open = park brake
fully released), or until the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the instrument cluster is put through the actuator test, the brake
indicator will be turned on, then off again during the bulb check portion of the test to confirm the
functionality of the LED and the cluster control circuitry.
The park brake switch on the park brake pedal mechanism provides a hard wired ground input to
the instrument cluster circuitry through the park brake switch sense circuit whenever the park brake
is applied or not fully released. The CAB continually monitors the ABS system circuits and sensors,
including the brake fluid level switch on the brake master cylinder reservoir, to decide whether the
system is in good operating condition. The CAB then sends the proper lamp-on or lamp-off
messages to the instrument cluster. If the CAB sends a lamp-on message after the bulb test, it
indicates that the CAB has detected a brake hydraulic system malfunction and/or that the ABS
system has become inoperative. The CAB will store a Diagnostic Trouble Code (DTC) for any
malfunction it detects.
For further diagnosis of the brake indicator or the instrument cluster circuitry that controls the LED,
refer to testing. The park brake switch input to the instrument cluster can be diagnosed using
conventional diagnostic tools and methods. For proper diagnosis of the brake fluid level switch, the
ABS, the CAB, the PCI data bus, or the electronic message inputs to the instrument cluster that
control the brake indicator, a diagnostic scan tool is required.

The hard wired park brake switch input to the EMIC may be diagnosed and tested using
conventional diagnostic tools and procedures. The wiring information includes wiring diagrams,
proper wire and connector repair procedures, details of wire harness routing and retention,
connector pin-out information and location views for the various wire harness connectors, splices
and grounds.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the EMIC,
the Controller Antilock Brake (CAB), the Programmable Communications Interface (PCI) data bus,
or the electronic message inputs also used by the EMIC to provide brake indicator operation. The
most reliable, efficient, and accurate means to diagnose the EMIC, the CAB, the PCI data bus, and
the electronic message inputs for the brake indicator operation requires the use of a diagnostic
scan tool.

Parking Brake Warning Switch: Description and Operation
The park brake switch (1) is located on the park brake lever mechanism on the cowl side inner
panel below the instrument panel, to the left of the steering column. This switch includes a
spade-type output terminal (3) that connects the switch to the vehicle electrical system through a
dedicated take out and connector of the body wire harness. The output terminal is integral to the
stationary contact within a molded plastic insulator.
A locating tab on the insulator engages a slot in the park brake lever mechanism for positive switch
location. External to the insulator is a movable leaf contact with an integral grounding lug (4) on
one end and an integral actuating lever and follower (2) on the opposite end. The switch is secured
to and grounded by a single screw to the park brake lever mechanism. The park brake switch
cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
The park brake switch is a normally closed, mechanically actuated leaf contact switch that is
operated by the park brake lever mechanism. The switch is grounded through its mounting to the
park brake lever mechanism and provides a ground input to the ElectroMechanical Instrument
Cluster (EMIC) (also sometimes referred to as the Cab Control Node/CCN) on a park brake switch
sense circuit whenever the park brake is applied, and opens this circuit whenever the park brake is
released. The park brake switch sense input to the EMIC is used for control of the brake indicator
and may also be used as a logic input for other electronic features in the vehicle.
The park brake switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the EMIC processing of the park brake switch sense input requires the
use of a diagnostic scan tool.

Hydraulic Brake Booster: Testing and Inspection
BOOSTER-HYDRO-BOOST BRAKE DIAGNOSIS AND TESTING
HYDRAULIC BOOSTER
The hydraulic booster uses hydraulic pressure from the power steering pump. Before diagnosing a
booster problem, first verify the power steering pump is operating properly. Perform the following
checks. ^
Check the power steering fluid level.
^ Check the brake fluid level.
^ Check all power steering hoses and lines for leaks and restrictions.
^ Check power steering pump pressure.
NOISES
The hydraulic booster unit will produce certain characteristic booster noises. The noises may occur
when the brake pedal is used in a manner not associated with normal braking or driving habits.
HISSING A hissing noise may be noticed when above normal brake pedal pressure is applied, 40
lbs. or above. The noise will be more noticeable if the vehicle is not moving. The noise will increase
with the brake pedal pressure and an increase of system operating temperature.
CLUNK-CHATTER-CLICKING A clunk-chatter-clicking may be noticed when the brake pedal is
released quickly, after above normal brake pedal pressure is applied 50 - 100 lbs..
BOOSTER FUNCTION TEST
With the engine off depress the brake pedal several times to discharge the accumulator. Then
depress the brake pedal using 40 lbs. of force and start the engine. The brake pedal should fall and
then push back against your foot. This indicates the booster is operating properly.
ACCUMULATOR LEAKDOWN
1. Start the engine, apply the brakes and turn the steering wheel from lock to lock. This will ensure
the accumulator is charged. Turn off the engine
and let the vehicle sit for one hour. After one hour there should be at least two power assisted
brake application with the engine off. If the system does not retain a charge the booster must be
replaced.
2. With the engine off depress the brake pedal several times to discharge the accumulator. Grasp
the accumulator and see if it wobbles or turns. If it
does the accumulator has lost a gas charge and the booster must be replaced.
SEAL LEAKAGE
If the booster leaks from any of the seals the booster assembly must be replaced.
^ INPUT ROD SEAL (3): Fluid leakage from rear end of the booster.
^ PISTON SEAL (6): Fluid leakage from vent at front of booster.
^ HOUSING SEAL (4): Fluid leakage between housing and housing cover.
^ SPOOL VALVE SEAL (7): Fluid leakage near spool plug.
^ RETURN PORT FITTING SEAL (8): Fluid leakage from port fitting.

Vacuum Brake Booster: Testing and Inspection
DIAGNOSIS AND TESTING
MASTER CYLINDER/POWER BOOSTER
1. Start engine and check booster vacuum hose connections. A hissing noise indicates vacuum
leak. Correct any vacuum leak before proceeding. 2. Stop engine and shift transmission into
Neutral. 3. Pump brake pedal until all vacuum reserve in booster is depleted. 4. Press and hold
brake pedal under light foot pressure. The pedal should hold firm, if the pedal falls away master
cylinder is faulty (internal
leakage).
5. Start engine and note pedal action. It should fall away slightly under light foot pressure then hold
firm. If no pedal action is discernible, power
booster, vacuum supply, or vacuum check valve is faulty. Proceed to the POWER BOOSTER
VACUUM TEST.
6. If the POWER BOOSTER VACUUM TEST passes, rebuild booster vacuum reserve as follows:
Release brake pedal. Increase engine speed to
1500 rpm, close the throttle and immediately turn off ignition to stop engine.
7. Wait a minimum of 90 seconds and try brake action again. Booster should provide two or more
vacuum assisted pedal applications. If vacuum
assist is not provided, booster is faulty.
POWER BOOSTER VACUUM TEST
1. Connect vacuum gauge (6) to booster check valve (4) with short length of hose (3) and T-fitting
(2). 2. Start and run engine at curb idle speed for one minute. 3. Observe the vacuum supply. If
vacuum supply is not adequate, repair vacuum supply. 4. Clamp (1) hose (7) shut between intake
vacuum source (5) and check valve (4). 5. Stop engine and observe vacuum gauge (6). 6. If
vacuum drops more than one inch HG (33 millibars) within 15 seconds, booster diaphragm or
check valve is faulty.
POWER BOOSTER CHECK VALVE TEST
1. Disconnect vacuum hose from check valve (1). 2. Remove check valve (1) and valve seal (2)
from booster (3). 3. Use a hand operated vacuum pump for test. 4. Apply 15 - 20 inches vacuum at
large end of check valve. 5. Plug off the small end to prevent vacuum leakage. 6. Vacuum should
hold steady. If gauge on pump indicates vacuum loss, check valve is faulty and should be replaced.

Parking Brake Warning Switch: Description and Operation
The park brake switch (1) is located on the park brake lever mechanism on the cowl side inner
panel below the instrument panel, to the left of the steering column. This switch includes a
spade-type output terminal (3) that connects the switch to the vehicle electrical system through a
dedicated take out and connector of the body wire harness. The output terminal is integral to the
stationary contact within a molded plastic insulator.
A locating tab on the insulator engages a slot in the park brake lever mechanism for positive switch
location. External to the insulator is a movable leaf contact with an integral grounding lug (4) on
one end and an integral actuating lever and follower (2) on the opposite end. The switch is secured
to and grounded by a single screw to the park brake lever mechanism. The park brake switch
cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
The park brake switch is a normally closed, mechanically actuated leaf contact switch that is
operated by the park brake lever mechanism. The switch is grounded through its mounting to the
park brake lever mechanism and provides a ground input to the ElectroMechanical Instrument
Cluster (EMIC) (also sometimes referred to as the Cab Control Node/CCN) on a park brake switch
sense circuit whenever the park brake is applied, and opens this circuit whenever the park brake is
released. The park brake switch sense input to the EMIC is used for control of the brake indicator
and may also be used as a logic input for other electronic features in the vehicle.
The park brake switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the EMIC processing of the park brake switch sense input requires the
use of a diagnostic scan tool.

Wheel Speed Sensor: Description and Operation
SENSOR- WHEEL SPEED-ABS-FRONT
DESCRIPTION
The ABS brake system uses 3 wheel speed sensors. A sensor is mounted to each front
hub/bearings. The third sensor is mounted on top of the rear axle differential housing.
OPERATION
The Wheel Speed Sensor consists of a magnet (1) surrounded by windings from a single strand of
wire (5). The sensor sends a small AC signal to the ABM. This signal is generated by magnetic
induction. The magnetic induction is created when a toothed sensor ring (exciter ring or tone
wheel) (4) passes the stationary magnetic WSS.
When the ring gear is rotated, the exciter ring (4) passes the tip of the WSS. As the exciter ring
tooth approaches the tip of the WSS, the magnetic lines of force expand, causing the magnetic
field to cut across the sensor's windings (5). This, in turn causes current to flow through the WSS
circuit in one direction. When the exciter ring tooth moves away from the sensor tip, the magnetic
lines of force collapse cutting the winding in the opposite direction. This causes the current to flow
in the opposite direction. Every time a tooth of the exciter ring passes the tip of the WSS, an AC
signal is generated current. Each AC signal (positive to negative signal or squarewave) is
interpreted by the ABM. It then compares the frequency of the sinewave to a time value to calculate
vehicle speed. The ABM continues to monitor the frequency to determine a deceleration rate that
would indicate a possible wheel-locking tendency.
The signal strength of any magnetic induction sensor is directly affected by: ^
Magnetic field strength; the stronger the magnetic field, the stronger the signal
^ Number of windings in the sensor; more windings provide a stronger signal
^ Exciter ring speed; the faster the exciter ring/tone wheel rotates, the stronger the signal will be
^ Distance (3) "air gap" between the exciter ring teeth and WSS; the closer the WSS is to the
exciter ring/tone wheel, the stronger the signal will be.
The WSS is not adjustable. A clearance specification has been established for manufacturing
tolerances. If the clearance is not within these specifications, then either the WSS or other
components may be damaged. The clearance between the WSS and the exciter ring is 0.005 0.050 inch.
The assembly plant performs a "Rolls Test" on every vehicle that leaves the assembly plant. One
of the test performed is a test of the WSS. To properly test the sensor, the assembly plant connects
test equipment to the Data Link Connector (DLC). This connector is located to the right of the
steering column and attached to the lower portion of the instrument panel. The rolls test terminal is
spliced to the WSS circuit. The vehicle is then driven on a set of rollers and the WSS output is
monitored for proper operation.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM (ECM Diesel) to
vary the battery charging rate. System voltage will be higher at colder temperatures and is
gradually reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20° F.

Starter Relay: Description and Operation
The starter relay is an electromechanical device that switches battery current to the pull-in coil of
the starter solenoid when ignition switch is turned to Start position. The starter relay is located in
the Power Distribution Center (PDC) in the engine compartment. See PDC cover for relay
identification and location.
The starter relay is a International Standards Organization (ISO) relay. Relays conforming to ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions.
The starter relay cannot be repaired or adjusted. If faulty or damaged, it must be replaced.
The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one
movable) electrical contacts. The movable (common feed) relay contact is held against one of the
fixed contacts (normally closed) by spring pressure. When electromagnetic coil is energized, it
draws the movable contact away from normally closed fixed contact, and holds it against the other
(normally open) fixed contact.
When electromagnetic coil is de-energized, spring pressure returns movable contact to normally
closed position. The resistor or diode is connected in parallel with electromagnetic coil within relay,
and helps to dissipate voltage spikes produced when coil is de-energized.

Starter Relay: Testing and Inspection
The starter relay is located in Power Distribution Center (PDC). Refer to PDC cover for relay
identification and location. For complete starter relay wiring circuit diagrams, refer to Wiring
Diagrams.
1. Remove starter relay from PDC 2. A relay in de-energized position should have continuity
between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go
to Step 3. If not OK, replace faulty relay.
3. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to
Step 4. If not OK, replace faulty relay. 4. Connect 12 V battery to terminals 85 an 86. There should
now be continuity between terminals 30 and 87, and no continuity between terminals
87A and 30. If OK, perform Relay Circuit Test that follows. If not OK, replace faulty relay.
RELAY CIRCUIT TEST
1. The relay common feed terminal cavity (30) is connected to battery voltage and should be hot at
all times. If OK, go to Step 2. If not OK, repair
open circuit to fuse in PDC as required.
2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized
position, but is not used for this application. Go to Step
3.
3. The relay normally open terminal (87) is connected to common feed terminal (30) in the
energized position. This terminal supplies battery voltage
to starter solenoid field coils. There should be continuity between cavity for relay terminal 87 and
starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair open circuit to starter
solenoid as required.
4. The coil battery terminal (86) is connected to electromagnet in relay. It is energized when ignition
switch is held in Start position. On vehicles with
manual transmission, clutch pedal must be fully depressed for this test. Check for battery voltage at
cavity for relay terminal 86 with ignition switch in Start position, and no voltage when ignition switch
is released to On position. If OK, go to Step 5. If not OK with automatic transmission, check for
open or short circuit to ignition switch and repair, if required. If circuit to ignition switch is OK, refer
to Ignition Switch and Key Lock Cylinder. If not OK with a manual transmission, check circuit
between relay and clutch pedal position switch for open or a short. If circuit is OK, refer to Clutch
Pedal Position Switch.
5. The coil ground terminal (85) is connected to the electromagnet in the relay. On vehicles with
manual transmission, it is grounded at all times. On
vehicles with automatic transmission, it is grounded through park/neutral position switch only when
gearshift selector lever is in Park or Neutral positions. Check for continuity to ground at cavity for
relay terminal 85. If not OK with manual transmission, repair circuit to ground as required. If not OK
with automatic transmission, check for pen or short circuit to park/neutral position switch and repair,
if required. If circuit to park/neutral position switch is OK, refer to Park/Neutral Position Switch,
Transmission.

Battery Cable: Description and Operation
The battery cables (1) and (3) are large gauge, stranded copper wires sheathed within a heavy
plastic or synthetic rubber insulating jacket. The wire used in the battery cables combines excellent
flexibility and reliability with high electrical current carrying capacity. The battery cables feature a
stamped brass clamping type female battery terminal crimped onto one end of the battery cable
wire and then solder-dipped. A square headed pinch-bolt and hex nut are installed at the open end
of the female battery terminal clamp. Large eyelet type terminals are crimped onto the opposite end
of the battery cable wire and then solder-dipped. The battery positive cable wires (1) have a red
insulating jacket to provide visual identification and feature a larger female battery terminal clamp
to allow connection to the larger battery positive terminal post. The battery negative cable wires (3)
have a black insulating jacket and a smaller female battery terminal clamp.
The battery cables cannot be repaired and, if damaged or inoperative they must be replaced. Both
the battery positive and negative cables are available for service replacement. Refer to the
appropriate wiring information for the location of the proper battery cable wire harness diagrams.
The wiring information also includes proper wire and connector repair procedures, further details on
wire harness routing and retention, as well as pin-out and location views for the various wire
harness connectors, splices and grounds.
The battery cables connect the battery terminal posts to the vehicle electrical system. These cables
also provide a path back to the battery for electrical current generated by the charging system for
restoring the voltage potential of the battery. The female battery terminal clamps on the ends of the
battery cable wires provide a strong and reliable connection of the battery cable to the battery
terminal posts. The terminal pinch bolts allow the female terminal clamps to be tightened around
the male terminal posts on the top of the battery. The eyelet terminals secured to the opposite ends
of the battery cable wires provide secure and reliable connection of the battery cables to the
vehicle electrical system.

Battery Cable: Testing and Inspection
A voltage drop test will determine if there is excessive resistance in the battery cable terminal
connections or the battery cables. If excessive resistance is found in the battery cable connections,
the connection point should be disassembled, cleaned of all corrosion or foreign material, then
reassembled. Following reassembly, check the voltage drop for the battery cable connection and
the battery cable again to confirm repair.
When performing the voltage drop test, it is important to remember that the voltage drop is giving
an indication of the resistance between the two points at which the voltmeter probes are attached.
EXAMPLE: When testing the resistance of the battery positive cable, touch the voltmeter leads to
the battery positive cable terminal clamp and to the battery positive cable eyelet terminal at the
starter solenoid B(+) terminal stud. If you probe the battery positive terminal post and the battery
positive cable eyelet terminal at the starter solenoid B(+) terminal stud, you are reading the
combined voltage drop in the battery positive cable terminal clamp-to-terminal post connection and
the battery positive cable.
VOLTAGE DROP TEST
WARNING: MODELS EQUIPPED WITH A DIESEL ENGINE HAVE AN AUTOMATIC SHUTDOWN
(ASD) RELAY LOCATED IN THE POWER DISTRIBUTION CENTER (PDC). REMOVAL OF THE
ASD RELAY MAY NOT PREVENT THE DIESEL ENGINE FROM STARTING. BE CERTAIN TO
DISCONNECT THE FUEL SHUTDOWN SOLENOID WIRE HARNESS CONNECTOR TO
PREVENT THE ENGINE FROM STARTING. FAILURE TO DO SO MAY RESULT IN PERSONAL
INJURY.
The following operation will require a voltmeter accurate to 1/10 (0.10) volt. Before performing this
test, be certain that the following procedures are accomplished:
- The battery is fully-charged and tested.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM (ECM Diesel) to
vary the battery charging rate. System voltage will be higher at colder temperatures and is
gradually reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20° F.

Alternator: Description and Operation
The generator is belt-driven by the engine using a serpentine type drive belt. It is serviced only as a
complete assembly. If the generator fails for any reason, the entire assembly must be replaced.
As the energized rotor begins to rotate within the generator, the spinning magnetic field induces a
current into the windings of the stator coil. Once the generator begins producing sufficient current, it
also provides the current needed to energize the rotor.
The stator winding connections deliver the induced alternating current to 3 positive and 3 negative
diodes for rectification. From the diodes, rectified direct current is delivered to the vehicle electrical
system through the generator battery terminal.
Although the generators appear the same externally, different generators with different output
ratings are used on this vehicle. Be certain that the replacement generator has the same output
rating and part number as the original unit. Refer to Generator Ratings in the Specifications at the
back for amperage ratings and part numbers.
Noise emitting from the generator may be caused by: worn, loose or defective bearings; a loose or
defective drive pulley; incorrect, worn, damaged or misadjusted fan drive belt; loose mounting
bolts; a misaligned drive pulley or a defective stator or diode.

Dodge Workshop Manuals > Starting and Charging > Charging System > Voltage Regulator > Component Information >
Description and Operation
Voltage Regulator: Description and Operation
The Electronic Voltage Regulator (EVR) is not a separate component. It is actually a voltage
regulating circuit located within the PCM (Powertrain Control Module) (within the ECM for diesel
engines). The EVR is not serviced separately. If replacement is necessary, the PCM must be
replaced.
The amount of direct current produced by the generator is controlled by EVR circuitry contained
within the PCM. This circuitry is connected in series with the generators second rotor field terminal
and its ground.
Voltage is regulated by cycling the ground path to control the strength of the rotor magnetic field.
The EVR circuitry monitors system line voltage (B+) and battery temperature. It then determines a
target charging voltage. If sensed battery voltage is 0.5 volts or lower than the target voltage, the
PCM grounds the field winding until sensed battery voltage is 0.5 volts above target voltage. A
circuit in the PCM cycles the ground side of the generator field up to 100 times per second
(100Hz), but has the capability to ground the field control wire 100% of the time (full field) to
achieve the target voltage. If the charging rate cannot be monitored (limp-in), a duty cycle of 25% is
used by the PCM in order to have some generator output.

Starter Relay: Description and Operation
The starter relay is an electromechanical device that switches battery current to the pull-in coil of
the starter solenoid when ignition switch is turned to Start position. The starter relay is located in
the Power Distribution Center (PDC) in the engine compartment. See PDC cover for relay
identification and location.
The starter relay is a International Standards Organization (ISO) relay. Relays conforming to ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions.
The starter relay cannot be repaired or adjusted. If faulty or damaged, it must be replaced.
The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one
movable) electrical contacts. The movable (common feed) relay contact is held against one of the
fixed contacts (normally closed) by spring pressure. When electromagnetic coil is energized, it
draws the movable contact away from normally closed fixed contact, and holds it against the other
(normally open) fixed contact.
When electromagnetic coil is de-energized, spring pressure returns movable contact to normally
closed position. The resistor or diode is connected in parallel with electromagnetic coil within relay,
and helps to dissipate voltage spikes produced when coil is de-energized.

The starter relay is located in Power Distribution Center (PDC). Refer to PDC cover for relay
identification and location. For complete starter relay wiring circuit diagrams, refer to Wiring
Diagrams.
1. Remove starter relay from PDC 2. A relay in de-energized position should have continuity
between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go
to Step 3. If not OK, replace faulty relay.
3. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to
Step 4. If not OK, replace faulty relay. 4. Connect 12 V battery to terminals 85 an 86. There should
now be continuity between terminals 30 and 87, and no continuity between terminals
87A and 30. If OK, perform Relay Circuit Test that follows. If not OK, replace faulty relay.
RELAY CIRCUIT TEST
1. The relay common feed terminal cavity (30) is connected to battery voltage and should be hot at
all times. If OK, go to Step 2. If not OK, repair
open circuit to fuse in PDC as required.
2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized
position, but is not used for this application. Go to Step
3.
3. The relay normally open terminal (87) is connected to common feed terminal (30) in the
energized position. This terminal supplies battery voltage
to starter solenoid field coils. There should be continuity between cavity for relay terminal 87 and
starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair open circuit to starter
solenoid as required.
4. The coil battery terminal (86) is connected to electromagnet in relay. It is energized when ignition
switch is held in Start position. On vehicles with
manual transmission, clutch pedal must be fully depressed for this test. Check for battery voltage at
cavity for relay terminal 86 with ignition switch in Start position, and no voltage when ignition switch
is released to On position. If OK, go to Step 5. If not OK with automatic transmission, check for
open or short circuit to ignition switch and repair, if required. If circuit to ignition switch is OK, refer
to Ignition Switch and Key Lock Cylinder. If not OK with a manual transmission, check circuit
between relay and clutch pedal position switch for open or a short. If circuit is OK, refer to Clutch
Pedal Position Switch.
5. The coil ground terminal (85) is connected to the electromagnet in the relay. On vehicles with
manual transmission, it is grounded at all times. On
vehicles with automatic transmission, it is grounded through park/neutral position switch only when
gearshift selector lever is in Park or Neutral positions. Check for continuity to ground at cavity for
relay terminal 85. If not OK with manual transmission, repair circuit to ground as required. If not OK
with automatic transmission, check for pen or short circuit to park/neutral position switch and repair,
if required. If circuit to park/neutral position switch is OK, refer to Park/Neutral Position Switch,

characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Auxiliary Power Outlet: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component
Information > Diagrams > Diagram Information and Instructions > Page 5411
- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Auxiliary Power Outlet: Description and Operation Instrument Panel
A cigar lighter outlet is installed to the left of the center stack area in the lower instrument panel.
The cigar lighter outlet is secured by a snap fit within the bezel.
The cigar lighter outlet, plastic cap and the knob and heating element unit are available for service
replacement. These components cannot be repaired and, if inoperative or damaged, they must be
replaced.
The cigar lighter consists of two major components: a knob and heating element unit, and the cigar
lighter base or outlet shell. The receptacle shell is connected to ground, and an insulated contact in
the bottom of the shell is connected to battery current. The cigar lighter receives battery voltage
from a fuse in the Integrated Power Module (IPM) when the ignition switch is in the Accessory or
Run positions.
The cigar lighter knob and heating element are encased within a spring-loaded housing, which also
features a sliding protective heat shield. When the knob and heating element are inserted in the
outlet shell, the heating element resistor coil is grounded through its housing to the outlet shell. If
the cigar lighter knob is pushed inward, the heat shield slides up toward the knob exposing the
heating element, and the heating element extends from the housing toward the insulated contact in
the bottom of the outlet shell.
Two small spring-clip retainers are located on either side of the insulated contact inside the bottom
of the outlet shell. These clips engage and hold the heating element against the insulated contact
long enough for the resistor coil to heat up. When the heating element is engaged with the contact,
battery current can flow through the resistor coil to ground, causing the resistor coil to heat.
When the resistor coil becomes sufficiently heated, excess heat radiates from the heating element
causing the spring-clips to expand. Once the spring-clips expand far enough to release the heating
element, the spring-loaded housing forces the knob and heating element to pop back outward to
their relaxed position. When the cigar lighter knob and element are pulled out of the outlet shell, the
protective heat shield slides downward on the housing so that the heating element is recessed and
shielded around its circumference for safety.

Auxiliary Power Outlet: Description and Operation Console
Two power outlets are utilized on this model. One in the instrument panel center lower bezel and
the other in the center console. The power outlet bases are secured by a snap fit within the
instrument panel or trim panel. A plastic protective cap snaps into the power outlet base when the
power outlet is not being used, and hangs from the power outlet base mount by an integral bail
strap while the power outlet is in use.
The power outlet receptacle unit and the accessory power outlet protective cap are available for
service. The power outlet receptacle cannot be repaired and, if faulty or damaged, it must be
replaced.
The power outlet base or receptacle shell is connected to ground, and an insulated contact in the
bottom of the shell is connected to battery current. The power outlet receives battery voltage from a
fuse in the integrated power module at all times.
While the power outlet is very similar to a cigar lighter base unit, it does not include the two small
spring-clip retainers inside the bottom of the receptacle shell that are used to secure the cigar
lighter heating element to the insulated contact.

Power Distribution Relay: Description and Operation
RELAY-TRAILER TOW
All vehicles are equipped with two trailer tow relays, one for the trailer right turn and brake lamps
and the other for the trailer left turn and brake lamps. The trailer tow relays are conventional
International Standards Organization (ISO) micro relays. Relays conforming to the ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions. Each relay is contained within a small, rectangular, molded plastic housing and
is connected to all of the required inputs and outputs through five integral male spade-type
terminals that extend from the relay base plate.
The trailer tow relays are located in the Power Distribution Center (PDC) in the engine
compartment near the battery. Refer to the layout label on the underside of the PDC cover for
specific relay cavity assignment information. A trailer tow relay cannot be adjusted or repaired and,
if faulty or damaged, the unit must be replaced.
The trailer tow relays are electromechanical switches that use a low current input from the Front
Control Module (FCM) (also referred to as the Integrated Power Module/IPM) to control a high
current output to trailer brake and turn signal lamps. Within each relay are an electromagnetic coil,
a movable contact and two fixed contact points. A resistor is connected in parallel with the coil, and
helps to dissipate voltage spikes and electromagnetic interference that can be generated as the
field of the relay coil collapses.
The movable common supply contact point is held against the fixed normally closed contact point
by spring pressure. When the relay coil is energized, an electromagnetic field is produced by the
coil windings. This field draws the movable contact away from the normally closed contact, and
holds it against the normally open contact. When the relay coil is de-energized, spring pressure
returns the movable contact back against the normally closed contact.
The inputs and outputs of the trailer tow relays include:
- Common Supply Terminal (30) - The common feed terminal is connected to a fused B(+) circuit at
all times.
- Coil Ground Terminal (85) - The coil ground terminal is connected to a fused B(+) circuit at all
times.
- Coil Battery Terminal (86) - The coil battery terminal is connected to a control output of the FCM
through a right or left trailer tow turn relay control circuit. The FCM controls trailer brake and turn
lamp operation by controlling a ground path through this circuit.
- Normally Open Terminal (87) - The normally open terminal is connected to the trailer lamps
through a right or left trailer tow turn relay output circuit and provides battery voltage to the right or
left trailer brake and turn lamps whenever the relay is energized.
- Normally Closed Terminal (87A) - The normally closed terminal is not connected to any circuit in
this application, but will have battery voltage present whenever the relay is de-energized.
The trailer tow relays can be diagnosed using conventional diagnostic tools and methods.

IOD FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse (1) that is disconnected within the
Integrated Power Module (IPM) when the vehicle is shipped from the factory. Dealer personnel are
to reconnect the IOD fuse in the IPM as part of the preparation procedures performed just prior to
new vehicle delivery.
A laser printed fuse layout map is integral to the IPM cover to ensure proper fuse identification. The
IOD fuse (1) is a 20 ampere mini blade-type fuse, located in fuse cavity # 51. The fuse is secured
within a black molded plastic fuse holder and puller unit that serves both as a tool for disconnecting
and reconnecting the fuse in the IPM cavity, and as a fuse holder that conveniently stores the fuse
in the same cavity after it has been disconnected.
CIRCUITS INCLUDED WITH IOD FUSE
- Cluster (CCN)
- Diagnostic Connector
- Map Lamps
- Glove Box Lamp
- Courtesy Lamps Radio
- Underhood Lamp
The term Ignition-Off Draw (IOD) identifies a normal condition where power is being drained from
the battery with the ignition switch in the Off position. The IOD fuse feeds the memory and sleep
mode functions for some of the electronic modules in the vehicle as well as various other
accessories that require battery current when the ignition switch is in the Off position. The only
reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle electrical system
during new vehicle transportation and pre-delivery storage to reduce battery depletion, while still
allowing vehicle operation so that the vehicle can be loaded, unloaded and moved as needed by
both vehicle transportation company and dealer personnel.
The IOD fuse is disconnected from Integrated Power Module (IPM) fuse cavity # 51 when the
vehicle is shipped from the assembly plant. Dealer personnel must reconnect the IOD fuse when
the vehicle is being prepared for delivery in order to restore full electrical system operation. Once
the vehicle is prepared for delivery, the IOD function of this fuse becomes transparent and the fuse
that has been assigned the IOD designation becomes only another Fused B(+) circuit fuse.
The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery
depletion when a vehicle is to be stored for periods not to exceed about thirty days. However, it
must be remembered that disconnecting the IOD fuse will not eliminate IOD, but only reduce this
normal condition. If a vehicle will be stored for more than about thirty days, the battery negative
cable should be disconnected to eliminate normal IOD; and, the battery should be tested and
recharged at regular intervals during the vehicle storage period to prevent the battery from
becoming discharged or damaged.

Power Distribution Relay: Description and Operation
RELAY-TRAILER TOW
All vehicles are equipped with two trailer tow relays, one for the trailer right turn and brake lamps
and the other for the trailer left turn and brake lamps. The trailer tow relays are conventional
International Standards Organization (ISO) micro relays. Relays conforming to the ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions. Each relay is contained within a small, rectangular, molded plastic housing and
is connected to all of the required inputs and outputs through five integral male spade-type
terminals that extend from the relay base plate.
The trailer tow relays are located in the Power Distribution Center (PDC) in the engine
compartment near the battery. Refer to the layout label on the underside of the PDC cover for
specific relay cavity assignment information. A trailer tow relay cannot be adjusted or repaired and,
if faulty or damaged, the unit must be replaced.
The trailer tow relays are electromechanical switches that use a low current input from the Front
Control Module (FCM) (also referred to as the Integrated Power Module/IPM) to control a high
current output to trailer brake and turn signal lamps. Within each relay are an electromagnetic coil,
a movable contact and two fixed contact points. A resistor is connected in parallel with the coil, and
helps to dissipate voltage spikes and electromagnetic interference that can be generated as the
field of the relay coil collapses.
The movable common supply contact point is held against the fixed normally closed contact point
by spring pressure. When the relay coil is energized, an electromagnetic field is produced by the
coil windings. This field draws the movable contact away from the normally closed contact, and
holds it against the normally open contact. When the relay coil is de-energized, spring pressure
returns the movable contact back against the normally closed contact.
The inputs and outputs of the trailer tow relays include:
- Common Supply Terminal (30) - The common feed terminal is connected to a fused B(+) circuit at
all times.
- Coil Ground Terminal (85) - The coil ground terminal is connected to a fused B(+) circuit at all
times.
- Coil Battery Terminal (86) - The coil battery terminal is connected to a control output of the FCM
through a right or left trailer tow turn relay control circuit. The FCM controls trailer brake and turn
lamp operation by controlling a ground path through this circuit.
- Normally Open Terminal (87) - The normally open terminal is connected to the trailer lamps
through a right or left trailer tow turn relay output circuit and provides battery voltage to the right or
left trailer brake and turn lamps whenever the relay is energized.
- Normally Closed Terminal (87A) - The normally closed terminal is not connected to any circuit in
this application, but will have battery voltage present whenever the relay is de-energized.
The trailer tow relays can be diagnosed using conventional diagnostic tools and methods.

Power Interrupt Connector/Switch: Description and Operation
IOD FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse (1) that is disconnected within the
Integrated Power Module (IPM) when the vehicle is shipped from the factory. Dealer personnel are
to reconnect the IOD fuse in the IPM as part of the preparation procedures performed just prior to
new vehicle delivery.
A laser printed fuse layout map is integral to the IPM cover to ensure proper fuse identification. The
IOD fuse (1) is a 20 ampere mini blade-type fuse, located in fuse cavity # 51. The fuse is secured
within a black molded plastic fuse holder and puller unit that serves both as a tool for disconnecting
and reconnecting the fuse in the IPM cavity, and as a fuse holder that conveniently stores the fuse
in the same cavity after it has been disconnected.
CIRCUITS INCLUDED WITH IOD FUSE
- Cluster (CCN)
- Diagnostic Connector
- Map Lamps
- Glove Box Lamp
- Courtesy Lamps Radio
- Underhood Lamp
The term Ignition-Off Draw (IOD) identifies a normal condition where power is being drained from
the battery with the ignition switch in the Off position. The IOD fuse feeds the memory and sleep
mode functions for some of the electronic modules in the vehicle as well as various other
accessories that require battery current when the ignition switch is in the Off position. The only
reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle electrical system
during new vehicle transportation and pre-delivery storage to reduce battery depletion, while still
allowing vehicle operation so that the vehicle can be loaded, unloaded and moved as needed by
both vehicle transportation company and dealer personnel.
The IOD fuse is disconnected from Integrated Power Module (IPM) fuse cavity # 51 when the
vehicle is shipped from the assembly plant. Dealer personnel must reconnect the IOD fuse when
the vehicle is being prepared for delivery in order to restore full electrical system operation. Once
the vehicle is prepared for delivery, the IOD function of this fuse becomes transparent and the fuse
that has been assigned the IOD designation becomes only another Fused B(+) circuit fuse.
The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery
depletion when a vehicle is to be stored for periods not to exceed about thirty days. However, it
must be remembered that disconnecting the IOD fuse will not eliminate IOD, but only reduce this
normal condition. If a vehicle will be stored for more than about thirty days, the battery negative
cable should be disconnected to eliminate normal IOD; and, the battery should be tested and
recharged at regular intervals during the vehicle storage period to prevent the battery from
becoming discharged or damaged.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams
> Diagram Information and Instructions > Page 5537
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagrams may appear to be

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams
> Diagram Information and Instructions > Page 5540
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Auxiliary Power Outlet: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.

STANDARD PROCEDURE - TESTING OF VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams
> Diagram Information and Instructions > Page 5556
- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Auxiliary Power Outlet: Description and Operation Instrument Panel
A cigar lighter outlet is installed to the left of the center stack area in the lower instrument panel.
The cigar lighter outlet is secured by a snap fit within the bezel.
The cigar lighter outlet, plastic cap and the knob and heating element unit are available for service
replacement. These components cannot be repaired and, if inoperative or damaged, they must be
replaced.
The cigar lighter consists of two major components: a knob and heating element unit, and the cigar
lighter base or outlet shell. The receptacle shell is connected to ground, and an insulated contact in
the bottom of the shell is connected to battery current. The cigar lighter receives battery voltage
from a fuse in the Integrated Power Module (IPM) when the ignition switch is in the Accessory or
Run positions.
The cigar lighter knob and heating element are encased within a spring-loaded housing, which also
features a sliding protective heat shield. When the knob and heating element are inserted in the
outlet shell, the heating element resistor coil is grounded through its housing to the outlet shell. If
the cigar lighter knob is pushed inward, the heat shield slides up toward the knob exposing the
heating element, and the heating element extends from the housing toward the insulated contact in
the bottom of the outlet shell.
Two small spring-clip retainers are located on either side of the insulated contact inside the bottom
of the outlet shell. These clips engage and hold the heating element against the insulated contact
long enough for the resistor coil to heat up. When the heating element is engaged with the contact,
battery current can flow through the resistor coil to ground, causing the resistor coil to heat.
When the resistor coil becomes sufficiently heated, excess heat radiates from the heating element
causing the spring-clips to expand. Once the spring-clips expand far enough to release the heating
element, the spring-loaded housing forces the knob and heating element to pop back outward to
their relaxed position. When the cigar lighter knob and element are pulled out of the outlet shell, the
protective heat shield slides downward on the housing so that the heating element is recessed and
shielded around its circumference for safety.

Auxiliary Power Outlet: Description and Operation Console
Two power outlets are utilized on this model. One in the instrument panel center lower bezel and
the other in the center console. The power outlet bases are secured by a snap fit within the
instrument panel or trim panel. A plastic protective cap snaps into the power outlet base when the
power outlet is not being used, and hangs from the power outlet base mount by an integral bail
strap while the power outlet is in use.
The power outlet receptacle unit and the accessory power outlet protective cap are available for
service. The power outlet receptacle cannot be repaired and, if faulty or damaged, it must be
replaced.
The power outlet base or receptacle shell is connected to ground, and an insulated contact in the
bottom of the shell is connected to battery current. The power outlet receives battery voltage from a
fuse in the integrated power module at all times.
While the power outlet is very similar to a cigar lighter base unit, it does not include the two small
spring-clip retainers inside the bottom of the receptacle shell that are used to secure the cigar
lighter heating element to the insulated contact.

Power Distribution Module: Testing and Inspection
FRONT CONTROL MODULE
The Front Control Module (FCM) is a printed circuit board based module with a on-board
micro-processor. The FCM interfaces with other electronic modules in the vehicle via the
Programmable Communications Interface (PCI) data bus. In order to obtain conclusive testing the
PCI data bus network and all of the electronic modules that provide inputs to, or receive outputs
from the FCM must be checked. All PCI communication faults must be resolved prior to further
diagnosing any FCM related issues.
The FCM was designed to be diagnosed with an appropriate diagnostic scan tool. The most
reliable, efficient, and accurate means to diagnose the FCM requires the use of an appropriate
scan tool and the proper Diagnostic Procedures.
Before any testing of the FCM is attempted, the battery should be fully charged and all wire
harness and ground connections inspected around the affected areas on the vehicle.

Power Distribution Relay: Description and Operation
RELAY-TRAILER TOW
All vehicles are equipped with two trailer tow relays, one for the trailer right turn and brake lamps
and the other for the trailer left turn and brake lamps. The trailer tow relays are conventional
International Standards Organization (ISO) micro relays. Relays conforming to the ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions. Each relay is contained within a small, rectangular, molded plastic housing and
is connected to all of the required inputs and outputs through five integral male spade-type
terminals that extend from the relay base plate.
The trailer tow relays are located in the Power Distribution Center (PDC) in the engine
compartment near the battery. Refer to the layout label on the underside of the PDC cover for
specific relay cavity assignment information. A trailer tow relay cannot be adjusted or repaired and,
if faulty or damaged, the unit must be replaced.
The trailer tow relays are electromechanical switches that use a low current input from the Front
Control Module (FCM) (also referred to as the Integrated Power Module/IPM) to control a high
current output to trailer brake and turn signal lamps. Within each relay are an electromagnetic coil,
a movable contact and two fixed contact points. A resistor is connected in parallel with the coil, and
helps to dissipate voltage spikes and electromagnetic interference that can be generated as the
field of the relay coil collapses.
The movable common supply contact point is held against the fixed normally closed contact point
by spring pressure. When the relay coil is energized, an electromagnetic field is produced by the
coil windings. This field draws the movable contact away from the normally closed contact, and
holds it against the normally open contact. When the relay coil is de-energized, spring pressure
returns the movable contact back against the normally closed contact.
The inputs and outputs of the trailer tow relays include:
- Common Supply Terminal (30) - The common feed terminal is connected to a fused B(+) circuit at
all times.
- Coil Ground Terminal (85) - The coil ground terminal is connected to a fused B(+) circuit at all
times.
- Coil Battery Terminal (86) - The coil battery terminal is connected to a control output of the FCM
through a right or left trailer tow turn relay control circuit. The FCM controls trailer brake and turn
lamp operation by controlling a ground path through this circuit.
- Normally Open Terminal (87) - The normally open terminal is connected to the trailer lamps
through a right or left trailer tow turn relay output circuit and provides battery voltage to the right or
left trailer brake and turn lamps whenever the relay is energized.
- Normally Closed Terminal (87A) - The normally closed terminal is not connected to any circuit in
this application, but will have battery voltage present whenever the relay is de-energized.
The trailer tow relays can be diagnosed using conventional diagnostic tools and methods.

IOD FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse (1) that is disconnected within the
Integrated Power Module (IPM) when the vehicle is shipped from the factory. Dealer personnel are
to reconnect the IOD fuse in the IPM as part of the preparation procedures performed just prior to
new vehicle delivery.
A laser printed fuse layout map is integral to the IPM cover to ensure proper fuse identification. The
IOD fuse (1) is a 20 ampere mini blade-type fuse, located in fuse cavity # 51. The fuse is secured
within a black molded plastic fuse holder and puller unit that serves both as a tool for disconnecting
and reconnecting the fuse in the IPM cavity, and as a fuse holder that conveniently stores the fuse
in the same cavity after it has been disconnected.
CIRCUITS INCLUDED WITH IOD FUSE
- Cluster (CCN)
- Diagnostic Connector
- Map Lamps
- Glove Box Lamp
- Courtesy Lamps Radio
- Underhood Lamp
The term Ignition-Off Draw (IOD) identifies a normal condition where power is being drained from
the battery with the ignition switch in the Off position. The IOD fuse feeds the memory and sleep
mode functions for some of the electronic modules in the vehicle as well as various other
accessories that require battery current when the ignition switch is in the Off position. The only
reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle electrical system
during new vehicle transportation and pre-delivery storage to reduce battery depletion, while still
allowing vehicle operation so that the vehicle can be loaded, unloaded and moved as needed by
both vehicle transportation company and dealer personnel.
The IOD fuse is disconnected from Integrated Power Module (IPM) fuse cavity # 51 when the
vehicle is shipped from the assembly plant. Dealer personnel must reconnect the IOD fuse when
the vehicle is being prepared for delivery in order to restore full electrical system operation. Once
the vehicle is prepared for delivery, the IOD function of this fuse becomes transparent and the fuse
that has been assigned the IOD designation becomes only another Fused B(+) circuit fuse.
The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery
depletion when a vehicle is to be stored for periods not to exceed about thirty days. However, it
must be remembered that disconnecting the IOD fuse will not eliminate IOD, but only reduce this
normal condition. If a vehicle will be stored for more than about thirty days, the battery negative
cable should be disconnected to eliminate normal IOD; and, the battery should be tested and
recharged at regular intervals during the vehicle storage period to prevent the battery from
becoming discharged or damaged.

Power Distribution Module: Description and Operation Integrated Power Module
The Integrated Power Module (IPM) is a combination of the Power Distribution Center (PDC) (1)
and the Front Control Module (FCM) (2). The PDC mates directly with the FCM to form the IPM.
The PDC is a printed circuit board based module that contains fuses and relays, while the FCM
contains the electronics controlling the IPM and other functions. The IPM is located in the engine
compartment, next to the battery and connects directly to the battery positive via a stud located on
top of the unit. The ground connection is via electrical connectors. The IPM provides the primary
means of voltage distribution and protection for the entire vehicle.
The molded plastic IPM housing includes a base and cover. The IPM cover is easily opened or
removed for service access by unscrewing the cover retaining nut and has a fuse and relay layout
map integral to the inside surface of the cover. This IPM housing base and cover are secured in
place via bolts to the left front fender support assembly.
Replaceable components of the IPM assembly are broken down into the following components:
- The Power Distribution Center (PDC)
- The IPM cover
- The Front Control Module (FCM)
- Complete IPM assembly that includes all three parts
All of the current from the battery and the generator output enters the integrated power module via
a stud on the top of the module. The integrated power module cover is removed to access the
fuses or relays. Internal connections of all of the power distribution center circuits is accomplished
by a combination of bus bars and a printed circuit board.

Power Distribution Module: Description and Operation Front Control Module
The Front Control Module (FCM) is a micro controller located in the left front corner of the engine
compartment. It is necessary to position the Integrated Power Module (IPM) aside in order to
access the front control module on this vehicle. The FCM mates to the Power Distribution Center
(PDC) to form the IPM. The IPM connects directly to the battery and provides the primary means of
circuit protection and power distribution for all vehicle electrical systems. The FCM controls power
to some of the vehicle systems electrical and electromechanical loads based on inputs received
from hard wired switch inputs and data received on the PCI bus circuit.
As messages are sent over the Programmable Communications Interface (PCI) data bus circuit,
the Front Control Module (FCM) reads these messages and controls power to some of the vehicles
electrical systems by completing the circuit to ground (low side driver) or completing the circuit to
12 volt power (high side driver). The following functions are Controlled by the FCM:
- Headlamp Power with Voltage Regulation
- Windshield Wiper "ON/OFF" Relay Actuation
- Windshield Wiper "HI/LO" Relay Actuation
- Windshield Washer Pump Motor
- Fog Lamp Relay Actuation
- Park Lamp Relay Actuation
- Horn Relay Actuation
The following inputs are Received/Monitored by the FCM:
- B+ Connection Detection
- Power Ground
- Ambient Temperature Sensing
- Ignition Switch Run
- Washer Fluid Level Switch
- Windshield Wiper Park Switch
- PCI Data Bus Circuit

Power Distribution Module: Testing and Inspection
FRONT CONTROL MODULE
The Front Control Module (FCM) is a printed circuit board based module with a on-board
micro-processor. The FCM interfaces with other electronic modules in the vehicle via the
Programmable Communications Interface (PCI) data bus. In order to obtain conclusive testing the
PCI data bus network and all of the electronic modules that provide inputs to, or receive outputs
from the FCM must be checked. All PCI communication faults must be resolved prior to further
diagnosing any FCM related issues.
The FCM was designed to be diagnosed with an appropriate diagnostic scan tool. The most
reliable, efficient, and accurate means to diagnose the FCM requires the use of an appropriate
scan tool and the proper Diagnostic Procedures.
Before any testing of the FCM is attempted, the battery should be fully charged and all wire
harness and ground connections inspected around the affected areas on the vehicle.

Alignment: Description and Operation
WHEEL ALIGNMENT
DESCRIPTION
NOTE: Suspension components with rubber/urethane bushings should be tightened with the
vehicle at normal ride height. It is important to have the springs supporting the weight of the vehicle
when the fasteners are torqued. If springs are not at their normal ride position, vehicle ride comfort
could be affected and premature bushing wear may occur.
Wheel alignment involves the correct positioning of the wheels in relation to the vehicle. The
positioning is accomplished through suspension and steering linkage adjustments. An alignment is
considered essential for efficient steering, good directional stability and to minimize tire wear. The
most important measurements of an alignment are caster, camber and toe.
CAUTION: Never attempt to modify suspension or steering components by heating or bending.
OPERATION
^ CASTER is the forward or rearward tilt of the steering knuckle from vertical. Tilting the top of the
knuckle forward provides less positive caster. Tilting the top of the knuckle rearward provides more
positive caster. Positive caster promotes directional stability. This angle enables the front wheels to
return to a straight ahead position after turns
^ CAMBER is the inward or outward tilt of the wheel relative to the center of the vehicle. Tilting the
top of the wheel inward provides negative camber. Tilting the top of the wheel outward provides
positive camber. Incorrect camber will cause wear on the inside or outside edge of the tire
^ TOE is the difference between the leading inside edges and trailing inside edges of the front tires.
Wheel toe position out of specification cause's unstable steering, uneven tire wear and steering
wheel off- center. The wheel toe position is the final front wheel alignment adjustment
^ THRUST ANGLE is the angle of the rear axle relative to the centerline of the vehicle. Incorrect
thrust angle can cause off-center steering and excessive tire wear. This angle is not adjustable,
damaged component(s) must be replaced to correct the thrust angle

PRE-ALIGNMENT INSPECTION
Before starting wheel alignment, the following inspection and necessary corrections must be
completed. Refer to Suspension and Steering System Diagnosis Chart for additional information. 1.
Inspect tires for size, air pressure and tread wear. 2. Inspect front wheel bearings for wear. 3.
Inspect front wheels for excessive radial or lateral runout and balance. 4. Inspect ball studs, linkage
pivot points and steering gear for looseness, roughness or binding. 5. Inspect suspension
components for wear and noise. 6. On 4x4 vehicles check suspension height (LD only). 7. Road
test the vehicle.

vehicle. 1. Inspect tires and set to correct pressure. 2. Jounce the front of the vehicle.
6. If value is greater than 61 mm (2.4 inches), tighten the torsion bar bolt until the specification is
achieved. 7. If value is less than 55 mm (2.1 inches), loosen the torsion bar bolt until the
specification is achieved. 8. Repeat the previous steps until the ride height is within specifications.
Height Adjustment - 4WD (LD)
HEIGHT ADJUSTMENT - 4WD (LD)
The vehicle suspension height MUST be measured and adjusted before performing wheel
alignment procedure. Also when front suspension components have been replaced. This
measurement must be performed with the vehicle supporting it's own weight and taken on both
sides of the vehicle.
To adjust the vehicle height turn the torsion bar adjustment bolt CLOCKWISE to raise the vehicle
and COUNTER CLOCKWISE to lower the vehicle.
CAUTION: ALWAYS raise the vehicle to the correct suspension height, NEVER lower the vehicle
to obtain the correct suspension height. If the vehicle suspension height is too high, lower the
vehicle below the height specification. Then raise the vehicle to the correct suspension height
specification. This will insure the vehicle maintains the proper suspension height.
NOTE: If a height adjustment has been made, perform height measurement again on both sides of
the vehicle.

Power Steering Pressure Switch: Description and Operation
SWITCH-POWER STEERING PRESSURE
DESCRIPTION
A pressure sensing switch is used in the power steering system. It is mounted on the high-pressure
steering hose. This switch will only be used with on HD vehicles with the 5.7L engines. There is no
pressure switch used for the 3.7L, 4.7L, 5.9L engines or the 5.7L LD vehicle pump.
OPERATION
The switch is used on the 5.7L V-8 engines HD vehicles only.
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high steering pump load and low engine rpm; such as
during parking maneuvers. The PCM increases the idle speed through the Idle Air Control (IAC)
motor. This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the Normally
Closed (NC) switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include:
engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only
exception to this requirement are published in the vehicle maintenance schedules, e.g. engine
coolant.
Exceptions to this recommendation include only those instances where a failure has occurred
and/or the system has become compromised, contaminated or overheated beyond the normal
operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission,
brake or steering systems. Chemicals contained in these products can damage the system
elastomeric components, and contaminate the component fluid, leading to loss of
system/component durability and service life. When necessary, only the original approved system
fluid should be used to flush these components using teamPSE(R) approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar
Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all
deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and
distilled water.

DISCUSSION:
Do not use fluids or supplements that contain Teflon as they will cause a restriction at the filter in
the power steering fluid reservoir, causing severe damage to the steering system. The power
steering fluid used in Chrysler Group vehicles is an engineered product, the addition of ANY
unapproved fluids or supplements can interfere with the proper function of the fluid and cause
damage to the steering system. To ensure the performance and durability of Chrysler Group
steering systems, use only Mopar Power Steering Fluid +4, ATF+4 Automatic Transmission Fluid,
or equivalent (MS-9602), in the power steering system.

Power Steering Fluid: Description and Operation
FLUID
NOTE: It is normal that some pressure will build up inside the reservoir, especially, with a warm
vehicle. A slight popping noise upon removal of the cap is normal. The fluid level should read
between the ADD and the FULL COLD marks. When the fluid is hot it should read between ADD
and FULL HOT marks. Only add fluid when the vehicle is cold.
The recommended fluid for the power steering system is Mopar(R) ATF +4.
Mopar(R) ATF+4, when new is red in color. The ATF+4 is dyed red so it can be identified from
other fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and
is not an indicator of fluid condition, As the vehicle is driven, the ATF+4 will begin to look darker in
color and may eventually become brown. THIS IS NORMAL. ATF+4 also has a unique odor that
may change with age. Consequently, odor and color cannot be used to indicate the fluid condition
or the need for a fluid change.

Power Steering Fluid: Testing and Inspection
POWER STEERING FLUID LEVEL CHECKING
WARNING: FLUID LEVEL SHOULD BE CHECKED WITH THE ENGINE OFF TO PREVENT
PERSONAL INJURY FROM MOVING PARTS.
CAUTION: MOPAR(R) ATF+4 is to be used in the power steering system. No other power steering
or automatic transmission fluid is to be used in the system. Damage may result to the power
steering pump and system if any other fluid is used, and do not overfill.
The power steering fluid level can be viewed on the dipstick attached to the filler cap. There are
two ranges listed on the dipstick, COLD and HOT. Before opening power steering system, wipe the
reservoir filler cap free of dirt and debris. Remove the cap and check the fluid level on its dipstick.
When the fluid is at normal ambient temperature, approximately 21°C to 27°C (70°F to 80°F), the
fluid level should read between the minimum and maximum area of the cold range. When the fluid
is hot, fluid level is allowed to read up to the highest end of the HOT range. Only add fluid when the
vehicle is cold.
Use only Mopar(R) ATF+4 Do not overfill the power steering system.

Power Steering Pressure Switch: Description and Operation
SWITCH-POWER STEERING PRESSURE
DESCRIPTION
A pressure sensing switch is used in the power steering system. It is mounted on the high-pressure
steering hose. This switch will only be used with on HD vehicles with the 5.7L engines. There is no
pressure switch used for the 3.7L, 4.7L, 5.9L engines or the 5.7L LD vehicle pump.
OPERATION
The switch is used on the 5.7L V-8 engines HD vehicles only.
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high steering pump load and low engine rpm; such as
during parking maneuvers. The PCM increases the idle speed through the Idle Air Control (IAC)
motor. This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the Normally
Closed (NC) switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

Suspension Strut / Shock Absorber: Testing and Inspection
SHOCK
A knocking or rattling noise from a shock absorber may be caused by movement between
mounting bushings and metal brackets or attaching components. These noises can usually be
stopped by tightening the attaching nuts. If the noise persists, inspect for damaged and worn
bushings, and attaching components. Repair as necessary if any of these conditions exist.
A squeaking noise from the shock absorber may be caused by the hydraulic valving and may be
intermittent. This condition is not repairable and the shock absorber must be replaced.
The shock absorbers are not refillable or adjustable. If a malfunction occurs, the shock absorber
must be replaced. To test a shock absorber, hold it in an upright position and force the piston in
and out of the cylinder four or five times. The action throughout each stroke should be smooth and
even.
The shock absorber bushings do not require any type of lubrication. Do not attempt to stop bushing
noise by lubricating them. Grease and mineral oil-base lubricants will deteriorate the bushing.

NOTE:
This information applies to any model equipped with Chrome Clad Wheels.
DISCUSSION:
Models equipped with Chrome Clad wheels require specific piloting on balance equipment to
properly center the wheel and prevent damage to the chrome clad surface. The chrome cladding is
not removable or replaceable and has cladding tabs that extend into the wheel bore. Traditional
high-taper cones will come into contact with the cladding tabs rather than properly seat on the hub
bore chamfer. Many modern aluminum wheel designs cannot be mounted with traditional cones.
Direct-Fit Collets should be used to properly mount clad wheels on balance equipment (Fig 1).
SPECIAL TOOLS/EQUIPMENT REQUIRED:
NOTE:
This kit includes the adapters for all Dodge, Chrysler & Jeep models with clad wheels. Individual
adapters for specific wheel sizes can be ordered separately. To order a kit or individual adapters,
contact Pentastar Service Equipment @ 1-800-223-5623.

Wheels: Description and Operation
WHEELS
DESCRIPTION
Original equipment wheels are designed for the specified Maximum Vehicle Capacity. All models
use steel or aluminum drop center wheels. Aluminum wheels require special balance weights and
alignment equipment.
1. On vehicles equipped with dual rear wheels, The rim is an eight stud hole pattern wheel. The
wheels have a flat mounting surface (1).
2. The slots (1) in the wheel must be aligned to provide access to the valve stem.
WHEEL DESIGN
The rim size is on the vehicle safety certification label located on the drivers door shut face. The
size of the rim is determined by the drivetrain package. Original equipment wheels/rims are
designed for operation up to the specified maximum vehicle capacity.
All models use stamped steel, cast aluminum or forged aluminum wheels. Every wheel has raised
sections between the rim flanges (1) and rim drop well (3) called safety humps.
Initial inflation of the tire forces the bead over these raised sections. In case of rapid loss of air
pressure, the raised sections help hold the tire on the

Service Bulletins > Page 5909
wheel.
The wheel studs and nuts are designed for specific applications. All aluminum and some steel
wheels have wheel stud nuts with an enlarged nose. This enlarged nose is necessary to ensure
proper retention of the wheels. Do not use replacement studs or nuts with a different design or
lesser quality.

Wheels: Testing and Inspection
WHEEL INSPECTION
Inspect wheels for:
- Excessive runout
- Dents, cracks or irregular bends
- Damaged wheel stud (lug) holes
- Air Leaks
NOTE: Do not attempt to repair a wheel by hammering, heating or welding.
If a wheel is damaged, an original equipment replacement wheel should be used. When obtaining
replacement wheels, they must be equivalent in load carrying capacity. The diameter, width, offset,
pilot hole and bolt circle of the wheel should be the same as the original wheel.
WARNING: Failure to use equivalent replacement wheels may adversely affect the safety and
handling of the vehicle.
WARNING: Replacement with used wheels is not recommended. The service history of the wheel
may have included severe treatment or very high mileage. The rim could fail without warning.
WARNING: DaimlerChrysler Corporation does not recommend that customers use "reconditioned"
wheels (wheels that have been damaged and repaired) because they can result in a sudden
catastrophic wheel failure which could cause loss of control and result in injury or death. For
clarification:
- Cosmetic refinishing for the purpose of repairing a superficial flaw is an acceptable procedure
providing it is limited to paint or clear coat only, the wheel is not modified in any way, and there is
no exposure to paint curing heat over 200 degrees Fahrenheit.
- Damaged wheels are those which have been bent, broken, cracked or sustained some other
physical damage which may have compromised the wheel structure.
- Repaired indicates that the wheel has been modified through bending, welding, heating,
straightening, or material removal to rectify damage.
- Re-plating of chrome plated wheels is not an acceptable procedure nor is chrome plating of
original equipment painted or polished wheels, as this may alter mechanical properties and affect
fatigue life.

Accumulator HVAC: Description and Operation
The A/C accumulator (5) is mounted in the engine compartment between the evaporator outlet tube
(2) and the A/C suction line (6). An integral mounting bracket (4) is used to secure the accumulator
to the dash panel (3). The A/C low side service port (1) is mounted to the top of the A/C
accumulator.
CAUTION: Use only O-ring seals specified for the vehicle. Failure to use the correct O-ring seal will
cause the refrigerant system connections to leak.
The A/C accumulator has no serviceable parts except for the rubber O-ring seals, low side service
port valve, cap and secondary retaining clips. The O-ring seals used on the connections are made
from a special type of rubber not affected by R-134a refrigerant. The O-ring seals must be replaced
whenever the A/C accumulator is removed and installed.
The A/C accumulator cannot be repaired and, if faulty or damaged, it must be replaced.
Refrigerant enters the A/C accumulator (1) mostly as a low pressure vapor through the inlet tube
(2). Any liquid, oil-laden refrigerant falls to the bottom of the canister, which acts as a separator. A
desiccant bag (3) is mounted inside the accumulator canister to absorb any moisture which may
have entered and become trapped within the refrigerant system A filter (4) is also mounted inside
the canister to trap any foreign material that may have entered the refrigerant system during
assembly. The low pressure vapor exits the A/C accumulator through the outlet tube (5). On this
model, the low side service port (6) is located at the top of the accumulator.
The A/C accumulator cannot be repaired. If the A/C accumulator is faulty or damaged, or if the
refrigerant system has been contaminated or left open to the atmosphere for an indeterminable
period or if the A/C compressor has failed, it must be replaced.

Air Door Actuator / Motor: Description and Operation Actuator-Blend Door
The blend door actuators are reversible, 12-volt direct current (DC), servo motors. Models with the
single zone heating-A/C system have a single blend-air door, which is controlled by a single blend
door actuator. Models with the dual zone system have two blend-air doors, which are controlled by
two blend door actuators.
The blend door actuator (1) for the single zone heating-A/C system is located near the center of the
HVAC housing (2), close to the dash panel.
For the dual zone heating-A/C system, the same blend door actuator used for the single zone
system becomes the driver side blend door actuator, which is mechanically connected to only the
driver side blend-air door. A second separate blend door actuator (3) located on the top of the
HVAC housing is mechanically connected to the passenger side blend-air door.
All actuators (1) are interchangeable with each other. Each actuator is contained within an identical
black molded plastic housing with an integral wire connector receptacle (2). Each actuator also has
an identical output shaft with splines (3) that connect it to its respective door linkage and three
integral mounting tabs (4) that allow the actuator to be secured to the HVAC housing. The blend
door actuators do not require mechanical indexing to the blend-air doors, as they are electronically
calibrated by the A/C-heater control.
The blend door actuators are connected to the A/C-heater control through the vehicle electrical
system by a dedicated two-wire lead and connector of the HVAC wire harness. The blend door
actuator(s) can move the blend-air door(s) in two directions. When the A/C-heater control pulls the
voltage on one side of the motor connection high and the other connection low, the blend-air door
will move in one direction. When the A/C-heater control reverses the

polarity of the voltage to the motor, the blend-air door moves in the opposite direction.
When the A/C-heater control makes the voltage to both connections high or both connections low,
the blend-air door stops and will not move. The A/C-heater control uses a pulse-count positioning
system to monitor the operation and relative position of the blend door actuator(s) and the blend-air
door(s). The A/C-heater control learns the blend-air door stop positions during the calibration
procedure and will store a diagnostic trouble code (DTC) for any problems it detects in the blend
door actuator circuits.
The blend door actuators are diagnosed using a DRBIII(R) scan tool.
The blend door actuators cannot be adjusted or repaired and, if faulty or damaged, they must be
replaced.

Air Door Actuator / Motor: Description and Operation Actuator-Mode Door
The mode door actuators are reversible, 12-volt direct current (DC) servo motors. The heating-A/C
systems on this vehicle use two mode door actuators. One for the panel/floor-air door and one for
the defrost-air door.
Both the panel/floor door actuator (1) and the defrost door actuator (2) are located on the driver
side end of the HVAC housing (3), close to the dash panel.
All actuators (1) are interchangeable with each other. Each actuator is contained within an identical
black molded plastic housing with an integral wire connector receptacle (2). Each actuator also has
an identical output shaft with splines (3) that connects it to its respective door linkage and three
integral mounting tabs (4) that allow the actuator to be secured to the HVAC housing. The mode
door actuators do not require mechanical indexing to the mode- air doors, as they are electronically
calibrated by the A/C-heater control.
The mode door actuators are connected to the A/C-heater control through the vehicle electrical
system by dedicated two-wire leads and connectors of the HVAC wire harness. The mode door
actuators can move the defrost-air door and the panel/floor-air door in two directions. When the
A/C-heater control pulls the voltage on one side of the motor connection high and the other
connection low, the mode-air door will move in one direction. When the A/C-heater control reverses
the polarity of the voltage to the motor, the mode-air door moves in the opposite direction.

The recirculation door actuator is connected to the heater-A/C control module through the vehicle
electrical system by a dedicated two-wire lead and connector of the HVAC wire harness. The
recirculation door actuator can move the recirculation-air door in two directions. When the
A/C-heater control pulls the voltage on one side of the motor connection high and the other
connection low, the recirculation-air door will move in one direction.
When the A/C-heater control makes the voltage to both connections high or both connections low,
the recirculation-air door stops and will not move. The A/C-heater control uses a pulse-count
positioning system to monitor the operation and relative position of the recirculation door actuator
and the recirculation-air door. The A/C-heater control learns the recirculation-air door stop positions
during the calibration procedure and will store a diagnostic trouble code (DTC) for any problems it
detects in the recirculation door actuator circuits.
The recirculation door actuator is diagnosed using a DRBIII(R) scan tool.
The recirculation door actuator cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.

Ambient Temperature Sensor / Switch HVAC: Description and Operation
The ambient temperature sensor is a variable resistor mounted to a bracket that is secured with a
screw to the left side of the radiator yoke, behind the radiator grille and in front of the engine
compartment.
The ambient temperature sensor cannot be adjusted or repaired and, if inoperative or damaged, it
must be replaced.
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal
sent by the Front Control Module (FCM). The resistance in the sensor changes as temperature
changes, changing the temperature sensor signal circuit voltage to the FCM. Based upon the
resistance in the sensor, the FCM senses a specific voltage on the temperature sensor signal
circuit. The FCM then translates the voltage into a temperature reading that it sent over the
Programmable Communications Interface (PCI) data bus circuit to other modules utilizing
temperature information.

Information > Locations > Page 5974
Ambient Temperature Sensor / Switch HVAC: Testing and Inspection
The temperature function is supported by the ambient temperature sensor, a wiring circuit, and
Front Control Module (FCM). If any portion of the ambient temperature sensor circuit fails or if
Programmable Communications Interface (PCI) Data Bus information is missing, a (- -) will appear
in the display in place of the temperature. When the sensor is exposed to temperatures above 55°
C (130° F), or if the sensor circuit is shorted, 55° C (130° F) will appear in the display in place of
the temperature, when the sensor is exposed to temperatures below - 40° C (- 40° F) or if the
sensor circuit is open, - 40° C (- 40° F) will appear in the display.
The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test,
and Sensor Circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the
temperature display is inoperative or incorrect, test the compass mini-trip computer.
SENSOR TEST
1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable.
Disconnect the ambient temperature sensor harness
connector.
2. Measure the resistance of the ambient temperature sensor. At - 40° C (- 40° F), the sensor
resistance is 336 kilohms. At 55° C (130° F), the
sensor resistance is 2.488 kilohms. The sensor resistance should read between these two values.
If OK, refer to Sensor Circuit Test. If not OK, replace the inoperative ambient temperature sensor.
SENSOR CIRCUIT TEST
For complete circuit diagrams, The wiring information includes wiring diagrams, proper wire and
connector repair procedures, details of wire harness routing and retention, connector pin-out
information and location views for the various wire harness connectors, splices and grounds.
1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable.
Disconnect the wire harness connectors from the
ambient temperature sensor and the FCM.
2. Connect a jumper wire between the two terminals in the body half of the ambient temperature
sensor harness connector. 3. Check for continuity between the sensor return circuit and the
ambient temperature sensor signal circuit cavities of the FCM harness connector.
There should be continuity. If OK, go to Step 4. If not OK, repair the open sensor return circuit or
ambient temperature sensor signal circuit to the ambient temperature sensor as required.
4. Check for continuity between the ambient temperature sensor signal circuit cavity of the FCM
harness connector and a good ground. There should
be no continuity. If OK, test the compass mini-trip computer operation. If not OK, repair the shorted
ambient temperature sensor signal circuit as required.

Blower Motor: Description and Operation
The blower motor (1) is a 12-volt, direct current (DC) motor mounted within a plastic housing with
an integral wire harness connector (2) and squirrel cage-type blower wheel (3) that is secured to
the blower motor shaft (4). The blower motor wheel is located in the HVAC air inlet housing which
is mounted to the passenger side end of the HVAC housing. The blower motor can be accessed for
service from underneath the instrument panel.
The blower motor is used to control the velocity of air moving through the HVAC housing by
spinning the blower wheel within the HVAC air inlet housing at the selected speed.
The blower motor will operate whenever the ignition switch is in the On position and the blower
motor control in any position except Off. The blower motor receives a fused battery feed circuit
through a fuse in the power distribution center (PDC) whenever the ignition switch is in the On
position.
Blower motor speed is controlled by regulating the ground path through or around the blower motor
resistor block and through the blower motor control located within the A/C-heater control.
The blower motor and blower motor wheel are factory balanced and cannot be adjusted or
repaired. If faulty or damaged, the blower motor and blower wheel must be replaced as an
assembly.

Blower Motor Resistor: Description and Operation
The blower motor resistor is mounted to the bottom of the HVAC housing, directly behind the glove
box. The blower motor resistor consists of a molded plastic mounting plate (1) with an integral wire
connector receptacle (2). Concealed behind the mounting plate are coiled resistor wires contained
within a ceramic heat sink (3).
The blower motor resistor is connected to the vehicle electrical system through a dedicated wire
lead and connector of the HVAC wire harness. The blower motor resistor has multiple resistor
wires, each of which will reduce the current flow through the blower motor to change the blower
motor speed.
The blower motor switch in the heating-A/C system directs the ground path for the blower motor
through the correct resistor wire to obtain the selected speed. With the blower motor control in the
lowest speed position, the ground path for the blower motor is applied through all of the resistor
wires. Each higher speed selected with the blower motor control applies the blower motor ground
path through fewer of the resistor wires, increasing the blower motor speed.
The blower motor resistor cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.

Compressor Clutch: Description and Operation
The A/C compressor clutch assembly consists of a stationary electromagnetic A/C clutch field coil
(4), pulley bearing and pulley assembly (3), clutch plate (2) and shims (7). These components
provide the means to engage and disengage the A/C compressor from the engine accessory drive
belt.
The A/C clutch field coil and the pulley bearing and pulley assembly are both retained on the nose
of the A/C compressor with snap rings (5 and 6). The clutch plate is splined to the compressor
shaft and secured with a bolt (1).
The A/C compressor clutch components provide the means to engage and disengage the A/C
compressor from the engine accessory drive belt. When the electromagnetic A/C clutch field coil is
energized, it magnetically draws the clutch plate into contact with the clutch pulley and drives the
compressor shaft. When the coil is not energized, the pulley freewheels on the clutch hub bearing,
which is part of the pulley assembly.
A/C compressor clutch engagement is controlled by the powertrain control module (PCM) or the
engine control module (ECM), depending on engine application.
The A/C compressor clutch components cannot be repaired and, if faulty or damaged, they must
be replaced.

Compressor Clutch: Initial Inspection and Diagnostic Overview
NOTE: The A/C clutch can be serviced in the vehicle. The refrigerant system can remain
fully-charged during compressor clutch, pulley and bearing assembly, or coil replacement.
Examine the friction surfaces of the pulley and the clutch plate (2) for wear. The pulley and clutch
plate should be replaced if there is excessive wear or scoring.
If the friction surfaces are oily, inspect the shaft and nose area of the A/C compressor (1) for
refrigerant oil. If refrigerant oil is found, the compressor shaft seal is leaking and the A/C
compressor must be replaced.
Check the pulley bearing for roughness or excessive leakage of grease. Replace the pulley and
bearing assembly, if required.

Compressor Clutch: Component Tests and General Diagnostics
After a new A/C compressor clutch has been installed, cycle the compressor clutch approximately
twenty times (five seconds on, then five seconds off). During this procedure, set the A/C-heater
controls to the A/C Recirculation Mode, the blower motor in the highest speed position, and the
engine speed at 1500 to 2000 rpm. This procedure (burnishing) will seat the opposing friction
surfaces and provide a higher compressor clutch torque capability.

Compressor Clutch Coil: Testing and Inspection
The A/C compressor clutch coil electrical circuit is controlled by the powertrain control module
(PCM) or the engine control module (ECM) (depending on engine application) through the A/C
clutch relay. Begin testing of a suspected compressor clutch coil problem by performing the
preliminary checks.
PRELIMINARY CHECKS
1. If no diagnostic trouble codes (DTCs) are found in the A/C-heater control and the powertrain
control module (PCM) or the engine control module
(ECM) (depending on engine application), go to Step 2. If any DTCs are found, repair as required.
2. If the A/C compressor clutch still will not engage, verify the refrigerant charge level. If the
refrigerant charge level is OK, go to TESTS. If the
refrigerant charge level is not OK, adjust the refrigerant charge as required.
TESTS
1. Verify the battery state of charge. 2. Connect an ammeter (0 to 10 ampere scale selected) in
series with the clutch coil feed terminal. Connect a voltmeter (0 to 20 volt scale selected)
to measure voltage across the battery and the clutch coil.
3. With the A/C-heater control in the A/C mode and the blower motor at low speed, start the engine
and allow it to run at a normal idle speed. 4. The A/C compressor clutch should engage
immediately, and the clutch coil supply voltage should be within two volts of the battery voltage. If
the
coil supply voltage is OK, go to Step 5. If the coil supply voltage is not within two volts of battery
voltage, test the clutch coil feed circuit for excessive voltage drop and repair as necessary
5. For the acceptable A/C clutch coil current draw specifications. Specifications apply for a work
area temperature of 21° C (70° F). If voltage is
more than 12.5 volts, add electrical loads by turning on electrical accessories until voltage reads
below 12.5 volts. a. If the A/C clutch coil current reading is zero, the coil is open and must be
replaced. b. If the A/C clutch coil current reading is above specifications, the coil is shorted and
must be replaced.

Compressor Clutch Relay: Description and Operation
The A/C clutch relay (1) is a International Standards Organization (ISO) micro-relay. Relays
conforming to the ISO specifications have common physical dimensions, current capacities,
terminal functions and patterns (2). The ISO micro-relay terminal functions are the same as a
conventional ISO relay. However, the ISO micro-relay terminal pattern (or footprint) is different, the
current capacity is lower, and the physical dimensions are smaller than those of the conventional
ISO relay
The A/C clutch relay is located in the integrated power module (IPM) in the engine compartment.
The ISO-standard A/C clutch micro-relay is an electromechanical switch that uses a low current
input from the powertrain control module (PCM) or engine control module (ECM) (depending on
engine application), to control the high current output to the A/C clutch field coil. The movable,
common feed relay contact is held against the fixed, normally closed relay contact by spring
pressure. When the electromagnetic relay coil is energized, it draws the movable common feed
relay contact away from the fixed, normally closed relay contact and, holds it against the fixed,
normally open relay contact. This action allows high current to flow to the A/C clutch field coil.
When the relay coil is de-energized, spring pressure returns the movable relay contact back
against the fixed, normally closed contact point. The resistor or diode is connected in parallel with
the relay coil, and helps to dissipate voltage spikes and electromagnetic interference that can be
generated as the electromagnetic field of the relay coil collapses.
The A/C clutch relay terminals are connected to the vehicle electrical system through a receptacle
in the integrated power module (IPM). The inputs and outputs of the A/C clutch relay include:
- The common feed terminal (30) receives a battery current input from a fuse in the IPM through a
fused B(+) circuit at all times.
- The coil ground terminal (86) receives a ground input from the PCM/ECM through the A/C clutch
relay control circuit only when the PCM/ECM electronically pulls the circuit to ground.
- The coil battery terminal (85) receives a battery current input from PTC 1 in the IPM through a
fused ignition switch output (run) circuit only when the ignition switch is in the On position.
- The normally open terminal (87) provides a battery current output to the A/C clutch coil through
the A/C clutch relay output circuit only when the A/C clutch relay coil is energized.
- The normally closed terminal (87A) is not connected to any circuit in this application, but provides
a battery current output only when the A/C clutch relay coil is de-energized.
The A/C clutch relay cannot be repaired and, if faulty or damaged, it must be replaced. Refer to the
appropriate wiring information for diagnosis and testing of the ISO-standard micro-relay and for
complete HVAC wiring diagrams.

Operation
Condenser HVAC: Description and Operation
The A/C condenser is located in the front of the engine compartment behind the grille. The A/C
condenser is a heat exchanger that allows the high-pressure refrigerant gas being discharged by
the A/C compressor to give up its heat to the air passing over the condenser fins, which causes the
refrigerant to cool and change to a liquid state.
When air passes through the fins of the A/C condenser, the high-pressure refrigerant gas within the
A/C condenser gives up its heat. The refrigerant then condenses as it leaves the A/C condenser
and becomes a high-pressure liquid. The volume of air flowing over the condenser fins is critical to
the proper cooling performance of the A/C system. Therefore, it is important that there are no
objects placed in front of the radiator grille openings at the front of the vehicle or foreign material on
the condenser fins that might obstruct proper air flow. Also, any factory-installed air seals or
shrouds must be properly reinstalled following radiator or A/C condenser service.
The A/C condenser cannot be repaired and, if faulty or damaged, it must be replaced.

Some vehicle operators may experience a musty odor from the A/C system, primarily at start up in
hot and humid climates. This odor may be the result of microbial growth on the cooling coil. During
normal A/C system operation, condensation forms in and around the NC cooling coil. When
airborne pollutants mix with this condensation, bacteria and fungi growth begins and odor results.
DIAGNOSIS:
If the operator describes, or the technician experiences a musty odor when operating the A/C
system, perform the appropriate Repair Procedure based on the vehicle model.

Hot/Humid > Page 6086
Some vehicle operators may experience a musty odor from the A/C system, primarily at start up in
hot and humid climates. This odor may be the result of microbial growth on the cooling coil. During
normal A/C system operation, condensation forms in and around the NC cooling coil. When
airborne pollutants mix with this condensation, bacteria and fungi growth begins and odor results.
DIAGNOSIS:
If the operator describes, or the technician experiences a musty odor when operating the A/C
system, perform the appropriate Repair Procedure based on the vehicle model.
PARTS REQUIRED:
A/C COOLING COIL CLEANER REQUIREMENTS BY VEHICLE MODEL

Evaporator Core: Description and Operation
The A/C evaporator (1) for the heating-A/C system is located within the HVAC housing, behind the
instrument panel. The A/C evaporator and it's insulator (2) are positioned in the HVAC housing so
that all air entering the housing must pass over the evaporator fins before it is distributed through
the heating-A/C system ducts and outlets. However, air passing over the evaporator fins will only
be conditioned when the A/C compressor is engaged and circulating refrigerant through the A/C
evaporator.
The A/C evaporator can be serviced by removing and disassembling the HVAC housing assembly.
Refrigerant enters the A/C evaporator through the A/C orifice tube as a low-temperature,
low-pressure mixture of liquid and gas. As air flows over the fins of the A/C evaporator, the
humidity in the air condenses on the fins, and the heat from the air is absorbed by the refrigerant.
Heat absorption causes the refrigerant to boil and vaporize. The refrigerant becomes a
low-pressure gas when it leaves the A/C evaporator.
The A/C evaporator cannot be repaired and, if faulty or damaged, it must be replaced.

Evaporator Temperature Sensor / Switch: Description and Operation
The evaporator temperature sensor is a two-wire temperature sensing element located at the
coldest point on the face of the A/C evaporator. The probe (1) for evaporator temperature sensor is
attached to the evaporator coil fins. The wire lead (2) for evaporator temperature sensor is routed
through an opening at the back of the HVAC housing and the connector (3) is attached to the
HVAC wire harness.
The evaporator temperature sensor monitors the surface temperature of A/C evaporator and
supplies an input signal to the A/C-heater control. The A/C-heater control uses the evaporator
temperature sensor input signal to optimize A/C system performance and to protect the A/C system
from evaporator freezing. The evaporator temperature sensor will change its internal resistance in
response to the temperatures it monitors and is connected to the A/C-heater control through sensor
ground circuit and a 5-volt reference signal circuit. As the temperature of the A/C evaporator
decreases, the internal resistance of the evaporator temperature sensor decreases.
The A/C-heater control uses the monitored voltage reading as an indication of evaporator
temperature. The A/C-heater control is programmed to respond to this input by requesting the
powertrain control module (PCM) or the engine control module (ECM) (depending on engine
application) to cycle the A/C compressor clutch as necessary to optimize A/C system performance
and to protect the A/C system from evaporator freezing.
The evaporator temperature sensor is diagnosed using a DRBIII(R) scan tool.
The evaporator temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it
must be replaced.

Description and Operation
Expansion Block/Orifice Tube: Description and Operation
The fixed A/C orifice tube is installed in the rear section of the A/C liquid line and provides a
restriction in the liquid refrigerant line between the A/C condenser and the A/C evaporator. This
restriction established the pressure differential between the high and low-pressure sides of the A/C
system. The A/C orifice tube includes a diffuser screen (1), O-ring seals (2) to seal it to the inner
wall of the A/C liquid line, an inlet filter screen (3) and the fixed orifice (4).
The fixed A/C orifice tube is used to meter the flow of liquid refrigerant into the A/C evaporator. The
high-pressure liquid refrigerant from the A/C condenser expands into a low-pressure liquid as it
passes through the metering orifice and diffuser screen of the A/C orifice tube.
The A/C orifice tube is not serviceable. The A/C orifice tube cannot be repaired and, if faulty or
plugged, it must be replaced as part of the A/C liquid line.

Expansion Block/Orifice Tube: Testing and Inspection
WARNING: THE A/C LIQUID LINE BETWEEN THE A/C CONDENSER AND THE A/C ORIFICE
TUBE CAN BECOME HOT ENOUGH TO BURN THE SKIN. USE EXTREME CAUTION WHEN
PERFORMING THE FOLLOWING TEST TO PREVENT POSSIBLE PERSONAL INJURY.
NOTE: The A/C orifice tube can be checked for proper operation using the following procedure.
However, the A/C orifice tube is only serviced as a part of the A/C liquid line. If the results of this
test indicate that the A/C orifice tube is obstructed or missing, the rear section of the A/C liquid line
must be replaced.
1. Confirm that the refrigerant system is properly charged. 2. Start the engine. Turn on the A/C
system and confirm that the compressor clutch is engaged. 3. Allow the A/C system to operate for
five minutes. 4. Lightly and cautiously touch the A/C liquid line near the condenser outlet at the
front of the engine compartment. The liquid line should be hot to
the touch.
5. Touch the A/C liquid line near the evaporator inlet at the rear of the engine compartment. The
liquid line should be cold to the touch. 6. If there is a distinct temperature differential between the
two ends of the A/C liquid line, the A/C orifice tube is in good condition. If there is little
or no detectable temperature differential between the two ends of the A/C liquid line, the A/C orifice
tube is obstructed or missing and the rear section of the A/C liquid line must be replaced.

Operation
Heater Core: Description and Operation
The heater core (1) is a heat exchanger made of rows of tubes and fins. The heater core is
positioned within the HVAC housing through the panel (2) located at the front of the HVAC housing.
The heater core tubes (3) are attached to the front of the heater core and are secured to the HVAC
housing by a bracket.
The heater core can be serviced by removing the HVAC housing assembly from the vehicle.
Engine coolant is circulated through the heater hoses to the heater core at all times. As the coolant
flows through the heater core, heat is removed from the engine and is transferred to the heater
core tubes and fins. Air directed through the heater core picks up the heat from the heater core
fins. The blend-air door(s) allows control of the heater output air temperature by regulating the
amount of air flowing through the heater core. The blower motor speed controls the volume of air
flowing through the HVAC housing.
The heater core cannot be repaired and, if faulty or damaged, it must be replaced.

Precautions
Hose/Line HVAC: Service Precautions
WARNING:
- THE A/C SYSTEM CONTAINS REFRIGERANT UNDER HIGH PRESSURE. REPAIRS SHOULD
ONLY BE PERFORMED BY QUALIFIED SERVICE PERSONNEL. SEVERE PERSONAL INJURY
OR DEATH MAY RESULT FROM IMPROPER SERVICE PROCEDURES.
- VOID BREATHING THE REFRIGERANT AND REFRIGERANT OIL VAPOR OR MIST.
EXPOSURE MAY IRRITATE THE EYES, NOSE, AND/OR THROAT. WEAR EYE PROTECTION
WHEN SERVICING THE A/C REFRIGERANT SYSTEM. SERIOUS EYE INJURY CAN RESULT
FROM DIRECT CONTACT WITH THE REFRIGERANT. IF EYE CONTACT OCCURS, SEEK
MEDICAL ATTENTION IMMEDIATELY.
- DO NOT EXPOSE THE REFRIGERANT TO OPEN FLAME. POISONOUS GAS IS CREATED
WHEN REFRIGERANT IS BURNED. AN ELECTRONIC LEAK DETECTOR IS RECOMMENDED.
SEVERE PERSONAL INJURY OR DEATH MAY RESULT FROM IMPROPER SERVICE
PROCEDURES.
- IF ACCIDENTAL SYSTEM DISCHARGE OCCURS, VENTILATE THE WORK AREA BEFORE
RESUMING SERVICE. LARGE AMOUNTS OF REFRIGERANT RELEASED IN A CLOSED
WORK AREA WILL DISPLACE THE OXYGEN AND CAUSE SUFFOCATION AND DEATH.
- THE EVAPORATION RATE OF R-134A REFRIGERANT AT AVERAGE TEMPERATURE AND
ALTITUDE IS EXTREMELY HIGH. AS A RESULT, ANYTHING THAT COMES IN CONTACT
WITH THE REFRIGERANT WILL FREEZE. ALWAYS PROTECT THE SKIN OR DELICATE
OBJECTS FROM DIRECT CONTACT WITH THE REFRIGERANT.
- THE R-134A SERVICE EQUIPMENT OR THE VEHICLE REFRIGERANT SYSTEM SHOULD
NOT BE PRESSURE TESTED OR LEAK TESTED WITH COMPRESSED AIR. SOME MIXTURES
OF AIR AND R-134A HAVE BEEN SHOWN TO BE COMBUSTIBLE AT ELEVATED
PRESSURES. THESE MIXTURES ARE POTENTIALLY DANGEROUS, AND MAY RESULT IN
FIRE OR EXPLOSION CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
- THE ENGINE COOLING SYSTEM IS DESIGNED TO DEVELOP INTERNAL PRESSURES OF
97 TO 123 KILOPASCALS (14 TO 18 POUNDS PER SQUARE INCH). DO NOT REMOVE OR
LOOSEN THE COOLANT PRESSURE CAP, CYLINDER BLOCK DRAIN PLUGS, RADIATOR
DRAIN, RADIATOR HOSES, HEATER HOSES, OR HOSE CLAMPS WHILE THE ENGINE
COOLING SYSTEM IS HOT AND UNDER PRESSURE. ALLOW THE VEHICLE TO COOL FOR A
MINIMUM OF 15 MINUTES BEFORE OPENING THE COOLING SYSTEM FOR SERVICE.
FAILURE TO OBSERVE THIS WARNING CAN RESULT IN SERIOUS BURNS FROM THE
HEATED ENGINE COOLANT.
CAUTION:
- Never add R-12 to a refrigerant system designed to use R-134a. Do not use R-12 equipment or
parts on a R-134a A/C system. These refrigerants are not compatible and damage to the A/C
system will result.
- Never use R-12 refrigerant oil in a A/C system designed to use R-134a refrigerant oil. These
refrigerant oils are not compatible and damage to the A/C system will result.
- The use of A/C system sealers may result in damage to A/C refrigerant
recovery/evacuation/recharging equipment and/or A/C system. Many federal, state/provincial and
local regulations prohibit the recharge of A/C systems with known leaks. DaimlerChrysler
recommends the detection of A/C system leaks through the use of approved leak detectors and
fluorescent leak detection dyes. Vehicles found with A/C system sealers should be treated as
contaminated and replacement of the entire A/C refrigerant system is recommended. A/C systems
found to be contaminated with A/C system sealers, A/C stop-leak products or seal conditioners
voids the warranty for the A/C system.
- Recover the refrigerant before opening any fitting or connection. Open the fittings with caution,
even after the system has been discharged. Never open or loosen a connection before recovering
the refrigerant.
- If equipped, do not remove the secondary retention clip from any spring-lock coupler connection
while the refrigerant system is under pressure. Recover the refrigerant before removing the
secondary retention clip. Open the fittings with caution, even after the system has been discharged.
Never open or loosen a connection before recovering the refrigerant.
- The internal parts of the A/C system will remain stable as long as moisture-free refrigerant and
refrigerant oil is used. Abnormal amounts of dirt, moisture or air can upset the chemical stability.
This may cause operational troubles or even serious damage if present in more than very small
quantities. Before disconnecting a component, clean the outside of the fittings thoroughly to
prevent contamination from entering the refrigerant system. Keep service tools and the work area
clean. Do not open the refrigerant system or uncap a replacement component until you are ready
to service the system. Immediately after disconnecting a component from the refrigerant system,
seal the open fittings with a cap or plug. This will prevent contamination from entering the A/C
system.
- Refrigerant oil will absorb moisture from the atmosphere if left uncapped. Do not open a container
of refrigerant oil until you are ready to use it. Replace the cap on the oil container immediately after
using. Store refrigerant oil only in a clean, airtight, and moisture-free container.
- Do not overcharge the refrigerant system. Overcharging will cause excessive compressor head
pressure and can cause compressor noise and A/C system failure.

Hose/Line HVAC: Description and Operation Coupler-Refrigerant Line
Spring-lock type refrigerant line couplers (1 and 4) are used to connect the A/C suction line (6) to
the A/C accumulator (5) and, the A/C accumulator and the A/C liquid line to the A/C evaporator
tubes (3). Secondary retaining clips (2 and 7) are installed over the connected couplers for added
protection.
The spring-lock refrigerant line couplers require special disconnect tools for disengaging the two
coupler halves.
The spring-lock type refrigerant line coupler is held together by a garter spring (6) inside a circular
cage (7) on the male half of the fitting (1). When the two coupler halves are connected, the flared
end of the female fitting (2) slips behind the garter spring inside the cage on the male fitting. The
garter spring and cage prevent the flared end of the female fitting from pulling out of the cage.
Some applications use a connection indicator ring (4) to help indicate when the two coupler halves
are fully connected.
Two O-rings (8) are used to seal the coupler connections. These O-rings are compatible with
R-134a refrigerant and must be replaced with O-rings made of the same material.
A secondary retaining clip (3) is installed over the connected coupler (5) for added protection.

Hose/Line HVAC: Description and Operation Plumbing
The A/C refrigerant lines and hoses are used to carry the refrigerant between the various A/C
system components. The refrigerant lines and hoses for the R-134a system on this vehicle consist
of a barrier-hose design with a nylon tube sandwiched between rubber layers. The nylon tube helps
to contain the R-134a refrigerant, which has a smaller molecular structure than R-12 refrigerant.
The ends of the refrigerant lines are made from lightweight aluminum or steel, and commonly use
braze-less fittings.
Any kinks or sharp bends in the refrigerant lines and hoses will reduce the capacity of the entire
A/C system and can reduce the flow of refrigerant in the system. The radius of all bends in the
flexible hose refrigerant lines should be at least ten times the diameter of the hose and the
refrigerant lines should be routed so they are at least 80 millimeters (3 inches) away from the
exhaust manifold(s) and exhaust pipe(s).
High pressures are produced in the refrigerant system when the A/C compressor is operating.
Extreme care must be exercised to make sure that each of the refrigerant system connections is
pressure-tight and leak free. It is a good practice to inspect all flexible hose refrigerant lines at least
once a year to make sure they are in good condition and properly routed.
The refrigerant lines and hoses are coupled to other A/C system components with block-type
fittings. An O-ring seal, or a flat steel gasket with an integral O-ring (dual plane seal), is used to
mate the refrigerant line fittings with A/C system components to ensure the integrity of the
refrigerant system.
The refrigerant lines and hoses cannot be repaired and, if faulty or damaged, they must be
replaced.

REFRIGERANT SYSTEM LEAKS
WARNING:
- R-134A SERVICE EQUIPMENT OR VEHICLE A/C SYSTEM SHOULD NOT BE PRESSURE
TESTED OR LEAK TESTED WITH COMPRESSED AIR. MIXTURE OF AIR AND R-134A CAN BE
COMBUSTIBLE AT ELEVATED PRESSURES. THESE MIXTURES ARE POTENTIALLY
DANGEROUS AND MAY RESULT IN FIRE OR EXPLOSION CAUSING PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH.
- AVOID BREATHING A/C REFRIGERANT AND LUBRICANT VAPOR OR MIST. EXPOSURE
MAY IRRITATE EYES, NOSE AND THROAT. USE ONLY APPROVED SERVICE EQUIPMENT
MEETING SAE REQUIREMENTS TO DISCHARGE R-134A SYSTEM. IF ACCIDENTAL SYSTEM
DISCHARGE OCCURS, VENTILATE WORK AREA BEFORE RESUMING SERVICE.
If the A/C system is not cooling properly, determine if the refrigerant system is fully charged with
R-134a. This is accomplished by performing a system Charge Level-Check or Fill. If while
performing this test A/C liquid line pressure is less than 345 kPa (50 psi) proceed to System Empty
procedure. If liquid line pressure is greater than 345 kPa (50 psi) proceed to System Low
procedure. If the refrigerant system is empty or low in refrigerant charge, a leak at any line fitting or
component seal is likely. A review of the fittings, lines and components for oily residue is an
indication of the leak location. To detect a leak in the refrigerant system, perform one of the
following procedures as indicated by the symptoms.
SYSTEM EMPTY
1. Evacuate the refrigerant system to the lowest degree of vacuum possible (approximately 28 in
Hg.). Determine if the system holds a vacuum for
15 minutes. If vacuum is held, a leak is probably not present. If system will not maintain vacuum
level, proceed to Step 2.
2. Prepare a 0.284 Kg. (10 oz.) refrigerant charge to be injected into the refrigerant system. 3.
Connect and dispense 0.284 Kg. (10 oz.) of refrigerant into the evacuated refrigerant system. 4.
Proceed to Step 2 of System Low procedure.
SYSTEM LOW
1. Determine if there is any R-134a refrigerant in the system. 2. Position the vehicle in a wind free
work area. This will aid in detecting small leaks. 3. Bring the refrigerant system up to operating
temperature and pressure. This is done by allowing the engine to run for five minutes with the A/C
system set to the following: Transmission in Park or Neutral with parking brake set
- Engine idling
- Mode control set to the outside air position
- Blower control set to the high speed position
- A/C set to the ON position
- All windows open
CAUTION: A leak detector only designed for R-12 refrigerant will not detect leaks in a R-134a
refrigerant system.
4. Shut the vehicle Off and wait 2-7 minutes. Then use an electronic leak detector that is designed
to detect R-134a refrigerant and search for leaks.
Fittings, lines or components that appear to be oily usually indicate a refrigerant leak. To inspect
the A/C evaporator for leaks, insert the leak detector probe into the drain tube opening or an air
outlet. A dye for R-134a is available to aid in leak detection. Use only DaimlerChrysler approved
refrigerant dye.

Description and Operation
Housing Assembly HVAC: Description and Operation
All models are equipped with a common HVAC housing assembly that combines A/C and heating
capabilities into a single unit mounted within the passenger compartment. The HVAC housing
assembly consists of the following:
- HVAC housing - The HVAC housing consists of an upper housing (7) and a lower housing (10)
that are attached together by screws and is mounted to the dash panel behind the instrument
panel. The HVAC housing contains the heater core (9), A/C evaporator (15), blend-air and
mode-air doors, and has mounting provisions for the air-door actuators (3, 5, 6 and 8), floor
distribution duct (4), blower motor (13), blower motor resistor, foam seals (12, 14 and 16) and the
HVAC wire harness (11).
- Air inlet housing - The air inlet housing (1) is mounted to the right end of the HVAC housing and
contains the recirculation-air door and has mounting provisions for the recirculation door actuator
(2).
The heating-A/C system is a blend-air type system. The blend-air doors control the amount of
conditioned air that is allowed to flow through, or around, the heater core. The dual zone heating
A/C system uses two blend door actuators while the single zone system uses only one blend door
actuator.
The A/C system is designed for the use of a non-CFC, R-134a refrigerant and uses an A/C
evaporator to cool and dehumidify the incoming air prior to blending it with the heated air. A
temperature control determines the discharge air temperature by operating the blend door
actuator(s), which moves the blend-air door(s). This allows an almost immediate control of the
output air temperature of the system. The mode door actuator operates the mode-air doors which
direct the flow of the conditioned air out the various air outlets, depending on the mode selected.
The recirculation door actuator operates the recirculation-air door which closes off the fresh air
intake and recirculates the air already inside the vehicle. The electric door actuators are connected
to the vehicle electrical system by the HVAC wire harness. The blower motor controls the velocity
of air flowing through the HVAC housing assembly by spinning the blower wheel within the HVAC
housings at the selected speed by use of the blower motor resistor.
NOTE: The air inlet housing does not need to be removed from the HVAC housing for service of
the recirculation-air door.
The HVAC housing must be removed from the vehicle and disassembled for service of the heater
core, A/C evaporator, evaporator temperature sensor, blend-air and mode-air doors.

Refrigerant: Description and Operation
The refrigerant used in this air conditioning system is a HydroFluoroCarbon (HFC), type R-134a.
Unlike R-12, which is a ChloroFluoroCarbon (CFC), R-134a refrigerant does not contain
ozone-depleting chlorine. R-134a refrigerant is a non-toxic, non-flammable, clear, and colorless
liquefied gas.
Even though R-134a does not contain chlorine, it must be reclaimed and recycled just like
CFC-type refrigerants. This is because R-134a is a greenhouse gas and can contribute to global
warming.
R-134a refrigerant is not compatible with R-12 refrigerant in an A/C system. Even a small amount
of R-12 refrigerant added to an R-134a refrigerant system will cause A/C compressor failure,
refrigerant oil sludge or poor A/C system performance. In addition, the polyalkylene glycol (PAG)
synthetic refrigerant oils used in an R-134a refrigerant system are not compatible with the
mineral-based refrigerant oils used in an R-12 refrigerant system.
R-134a refrigerant system service ports, service tool couplers and refrigerant dispensing bottles
have all been designed with unique fittings to ensure that an R-134a refrigerant system is not
accidentally contaminated with the wrong refrigerant (R-12). There are also labels posted in the

Refrigerant Oil: Description and Operation
The refrigerant oil used in R-134a refrigerant systems is a synthetic-based, polyalkylene glycol
(PAG), wax-free lubricant. Mineral-based R-12 refrigerant oils are not compatible with PAG oils,
and should never be introduced to an R-134a refrigerant system.
There are different PAG oils available, and each contains a different additive package. Use only
refrigerant oil of the same type as recommended to service the refrigerant system (always refer to
the specification tag included with the replacement A/C compressor or the underhood A/C system
specification tag).
The Sanden SD-7 A/C compressor used in this vehicle is designed to use ND-15 PAG refrigerant
oil. Use only this type of refrigerant oil when servicing the A/C compressor for the 5.9L Diesel
engine.
The Denso 10S17 A/C compressor used in this vehicle is designed to use ND-8 PAG refrigerant
oil. Use only this type of refrigerant oil when servicing the A/C compressor for the 3.7L, 4.7L, 5.7L
and 8.3L engines.
After performing any refrigerant recovery or recycling operation, always replenish the refrigerant
system with the same amount of the recommended refrigerant oil as was removed. Too little
refrigerant oil can cause A/C compressor damage, and too much can reduce A/C system
performance.
PAG refrigerant oil is more hygroscopic than mineral oil, and will absorb any moisture it comes into
contact with, even moisture in the air. The PAG oil container should always be kept tightly capped
until it is ready to be used. After use, recap the oil container immediately to prevent moisture
contamination.

Refrigerant Oil: Service and Repair
REFRIGERANT OIL LEVEL
When an A/C system is assembled at the factory, all components except the A/C compressor are
refrigerant oil free. After the refrigerant system has been charged and operated, the refrigerant oil
in the A/C compressor is dispersed throughout the refrigerant system. The accumulator, A/C
evaporator, A/C condenser and the A/C compressor will each retain a significant amount of the
needed refrigerant oil.
It is important to have the correct amount of refrigerant oil in the A/C system. This ensures proper
lubrication of the A/C compressor. Too little oil will result in damage to the A/C compressor, while
too much oil will reduce the cooling capacity of the A/C system and consequently result in higher
discharge air temperatures.
CAUTION: The refrigerant oil in the R-134a A/C system is unique depending on the A/C
compressor used. Use only PAG oils that are designed to work with R-134a refrigerant and the A/C
compressor in the vehicle. Always refer to the underhood A/C System Specification Label for the
correct oil designation. The oil container should be kept tightly capped until it is ready for use and
then tightly capped after use to prevent contamination from dirt and moisture. Refrigerant oil will
quickly absorb any moisture it comes in contact with, therefore, special effort must be used to keep
all R-134a system components moisture-free. Moisture in the refrigerant oil is very difficult to
remove and will cause a reliability problem with the A/C compressor.
NOTE: Most reclaim/recycling equipment will measure the lubricant being removed during
recovery. This amount of lubricant should be added back into the system. Refer to the
reclaim/recycling equipment manufacturers instructions.
It will not be necessary to check the oil level in the A/C compressor or to add oil, unless there has
been an oil loss. An oil loss may occur due to a rupture or leak from a refrigerant line, a connector
fitting, a component, or a component seal. If a leak occurs, add 30 milliliters (1 fluid ounce) of
refrigerant oil to the refrigerant system after the repair has been made. Refrigerant oil loss will be
evident at the leak point by the presence of a wet, shiny surface around the leak.
Refrigerant Oil Capacities
Refrigerant oil must be added when an accumulator, A/C evaporator or A/C condenser is replaced.
See the Refrigerant Oil Capacities chart. When an A/C compressor is replaced, the refrigerant oil
must be drained from the old compressor and measured. Drain all of the refrigerant oil from the
new A/C compressor, then fill the new compressor with the same amount of refrigerant oil that was
drained out of the old compressor.

Refrigerant Pressure Sensor / Switch: Description and Operation
The A/C pressure transducer (1) is a switch that is installed on a fitting located on the A/C
discharge line. An internally threaded fitting on the A/C pressure transducer connects it to the
externally threaded Schrader-type fitting on the A/C discharge line. A rubber O-ring seals the
connection between the A/C pressure transducer and the discharge line fitting. The A/C pressure
transducer is connected to the vehicle electrical system by a molded plastic connector with three
terminals.
The A/C pressure transducer monitors the pressures in the high side of the refrigerant system
through its connection to a fitting on the A/C discharge line. The A/C pressure transducer will
change its internal resistance in response to the pressures it monitors. A Schrader-type valve in the
A/C discharge line fitting permits the A/C pressure transducer to be removed or installed without
disturbing the refrigerant in the A/C system.
The A/C pressure transducer will change its internal resistance in response to the pressures it
monitors. The powertrain control module (PCM) or the engine control module (ECM) (depending on
engine application) provides a five volt reference signal and a sensor ground to the A/C pressure
transducer, then monitors the output voltage of the transducer on a sensor return circuit to
determine refrigerant pressure. The PCM/ECM is programmed to respond to this and other sensor
inputs by controlling the operation of the A/C compressor clutch and the radiator cooling fan to help
optimize A/C system performance and to protect the system components from damage. The PCM
will disengage the A/C compressor clutch when high side pressure rises above 3172 kPa (460 psi)
and re-engage the clutch when high side pressure drops below 1999 kPa (290 psi). The A/C
pressure transducer will also disengage the A/C compressor clutch if the high side pressure drops
below 193 kPa (28 psi) and will re-engage the clutch when the high side pressure rises above 234
kPa (34 psi). If the refrigerant pressure rises above 1655 kPa (240 psi), the PCM will actuate the
cooling fan. The A/C pressure transducer signal to the PCM/ECM will also prevent the A/C
compressor clutch from engaging when ambient temperatures are below about 10 ° C (50° F) due
to the pressure/temperature relationship of the refrigerant.The A/C pressure transducer input to the
PCM/ECM will also prevent the A/C compressor clutch from engaging when ambient temperatures
are below about 10° C (50° F) due to the pressure/temperature relationship of the refrigerant.
The A/C pressure transducer is diagnosed using a DRBIII(R) scan tool.
The A/C pressure transducer cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.

Compressor Clutch Relay: Description and Operation
The A/C clutch relay (1) is a International Standards Organization (ISO) micro-relay. Relays
conforming to the ISO specifications have common physical dimensions, current capacities,
terminal functions and patterns (2). The ISO micro-relay terminal functions are the same as a
conventional ISO relay. However, the ISO micro-relay terminal pattern (or footprint) is different, the
current capacity is lower, and the physical dimensions are smaller than those of the conventional
ISO relay
The A/C clutch relay is located in the integrated power module (IPM) in the engine compartment.
The ISO-standard A/C clutch micro-relay is an electromechanical switch that uses a low current
input from the powertrain control module (PCM) or engine control module (ECM) (depending on
engine application), to control the high current output to the A/C clutch field coil. The movable,
common feed relay contact is held against the fixed, normally closed relay contact by spring
pressure. When the electromagnetic relay coil is energized, it draws the movable common feed
relay contact away from the fixed, normally closed relay contact and, holds it against the fixed,
normally open relay contact. This action allows high current to flow to the A/C clutch field coil.
When the relay coil is de-energized, spring pressure returns the movable relay contact back
against the fixed, normally closed contact point. The resistor or diode is connected in parallel with
the relay coil, and helps to dissipate voltage spikes and electromagnetic interference that can be
generated as the electromagnetic field of the relay coil collapses.
The A/C clutch relay terminals are connected to the vehicle electrical system through a receptacle
in the integrated power module (IPM). The inputs and outputs of the A/C clutch relay include:
- The common feed terminal (30) receives a battery current input from a fuse in the IPM through a
fused B(+) circuit at all times.
- The coil ground terminal (86) receives a ground input from the PCM/ECM through the A/C clutch
relay control circuit only when the PCM/ECM electronically pulls the circuit to ground.
- The coil battery terminal (85) receives a battery current input from PTC 1 in the IPM through a
fused ignition switch output (run) circuit only when the ignition switch is in the On position.
- The normally open terminal (87) provides a battery current output to the A/C clutch coil through
the A/C clutch relay output circuit only when the A/C clutch relay coil is energized.
- The normally closed terminal (87A) is not connected to any circuit in this application, but provides
a battery current output only when the A/C clutch relay coil is de-energized.
The A/C clutch relay cannot be repaired and, if faulty or damaged, it must be replaced. Refer to the
appropriate wiring information for diagnosis and testing of the ISO-standard micro-relay and for
complete HVAC wiring diagrams.

Ambient Temperature Sensor / Switch HVAC: Description and Operation
The ambient temperature sensor is a variable resistor mounted to a bracket that is secured with a
screw to the left side of the radiator yoke, behind the radiator grille and in front of the engine
compartment.
The ambient temperature sensor cannot be adjusted or repaired and, if inoperative or damaged, it
must be replaced.
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal
sent by the Front Control Module (FCM). The resistance in the sensor changes as temperature
changes, changing the temperature sensor signal circuit voltage to the FCM. Based upon the
resistance in the sensor, the FCM senses a specific voltage on the temperature sensor signal
circuit. The FCM then translates the voltage into a temperature reading that it sent over the
Programmable Communications Interface (PCI) data bus circuit to other modules utilizing
temperature information.

Evaporator Temperature Sensor / Switch: Description and Operation
The evaporator temperature sensor is a two-wire temperature sensing element located at the
coldest point on the face of the A/C evaporator. The probe (1) for evaporator temperature sensor is
attached to the evaporator coil fins. The wire lead (2) for evaporator temperature sensor is routed
through an opening at the back of the HVAC housing and the connector (3) is attached to the
HVAC wire harness.
The evaporator temperature sensor monitors the surface temperature of A/C evaporator and
supplies an input signal to the A/C-heater control. The A/C-heater control uses the evaporator
temperature sensor input signal to optimize A/C system performance and to protect the A/C system
from evaporator freezing. The evaporator temperature sensor will change its internal resistance in
response to the temperatures it monitors and is connected to the A/C-heater control through sensor
ground circuit and a 5-volt reference signal circuit. As the temperature of the A/C evaporator
decreases, the internal resistance of the evaporator temperature sensor decreases.
The A/C-heater control uses the monitored voltage reading as an indication of evaporator
temperature. The A/C-heater control is programmed to respond to this input by requesting the
powertrain control module (PCM) or the engine control module (ECM) (depending on engine
application) to cycle the A/C compressor clutch as necessary to optimize A/C system performance
and to protect the A/C system from evaporator freezing.

Repairs and Inspections Required After a Collision: Service and Repair Air Bag System
Any vehicle which is to be returned to use following a supplemental restraint deployment, must
have the deployed restraints replaced. In addition, if the driver airbag has been deployed, the
clockspring must be replaced. If the passenger airbag is deployed, the passenger airbag door must
be replaced. The seat belt tensioners are deployed by the same signal that deploys the driver and
passenger airbags and must also be replaced if either front airbag has been deployed. If a side
curtain airbag has been deployed, the complete airbag unit, the headliner, as well as the upper A,
B, and C-pillar trim must be replaced. These components are not intended for reuse and will be
damaged or weakened as a result of a supplemental restraint deployment, which may or may not
be obvious during a visual inspection.
On vehicles with an optional sunroof, the sunroof drain tubes and hoses must be closely inspected
following a side curtain airbag deployment. It is also critical that the mounting surfaces and/or
mounting brackets for the Airbag Control Module (ACM) and the side impact sensors be closely
inspected and restored to their original conditions following any vehicle impact damage. Because
the ACM and each impact sensor are used by the supplemental restraint system to monitor or
confirm the direction and severity of a vehicle impact, improper orientation or insecure fastening of
these components may cause airbags not to deploy when required, or to deploy when not required.
All other vehicle components should be closely inspected following any supplemental restraint
deployment, but are to be replaced only as required by the extent of the visible damage incurred.

REPAIRS AND INSPECTIONS REQUIRED AFTER A COLLISION
RESTRAINT SYSTEM
After a impact where an airbag has been deployed due to a collision, the following MUST be
replaced: 1. Front Seat Belts and Retractors (driver and passenger) with integral Tensioners. 2.
After an impact that deploys the airbag, the seat belt tensioner assembly must be replaced.
WARNING: WHEN THE FRONT AIRBAG IS DEPLOYED, THE TENSIONER WILL HAVE
DEPLOYED ALSO AND MUST BE REPLACED.
3. Do not reuse the bolts attaching the seat belt retractor to the seat frame. Failure to follow proper
installation procedure may result in the seat track
latch pins not being synchronized.
4. Inspect the condition of the shoulder/lap belt. replace the retractor if the belt is cut, frayed, torn,
or damaged in any way. The rear seat back
retaining nut also serves as the center seat belt anchor. Be certain to torque this nut.
5. All seat belts should be closely inspected for cuts, tears, fraying, or damage in any way following
any frontal impact or airbag deployment. The
seat belts are to be replaced when visible damage is incurred. Inspect the Lower Anchors and
Tether for Children (LATCH) child restraint anchors for damage after an impact event and replace
as needed.
6. During, and following, any child restraint anchor service, due to impact event or vehicle repair,
carefully inspect all mounting hardware, tether
straps and anchors for proper installation, operation, or damage. if a child restraint anchor is found
damaged in any way, the anchor must be replaced with the seat assembly. failure to do so could
result in occupant personal injury or death.
NOTE: Never attempt to repair a seat belt component. always replace damaged or faulty seat belt
components with the correct, new and unused replacement parts.
VEHICLES EQUIPPED WITH THE OCCUPANT CLASSIFICATION SYSTEM (OCS)
If any of the Occupant Classification System (OCS) components of the passenger side front seat
cushion require replacement, they are serviced only as a factory-calibrated, assembled, and
tamper-evident service replacement package. This package includes the assembled frame,
springs, pad, seat weight bladder and pressure sensor, foam, wiring and a calibrated OCM. When
installing this package, always replace all of the existing components with the new components as
a unit. Do not attempt to separate or disconnect any of the new OCS components contained in the
service replacement package from each other, and do not attempt to reuse any of the replaced
components in this or any other vehicle.
CAUTION: Never replace both the Airbag Control Module (ACM) and the Occupant Classification
Module (OCM) at the same time. If both require replacement, replace one. Then perform the
supplemental restraint verification test before replacing the other. Both the ACM and the OCM
store OCS calibration data, which they transfer to one another when one of them is replaced. If
both are replaced at the same time, an irreversible fault will be set in both modules.

Air Bag: Description and Operation Air Bag-Side Curtain
Optional side curtain airbags are available for this model when it is also equipped with dual front
airbags. These airbags are passive, inflatable, Supplemental Restraint System (SRS) components,
and vehicles with this equipment can be readily identified by a molded identification trim button with
the "SRS - AIR-BAG" logo located on the headliner above each A-pillar, or above each B-pillar on
quad cab models. This system is designed to reduce injuries to the vehicle occupants in the event
of a side impact collision.
Vehicles equipped with side curtain airbags have two individually controlled curtain airbag units.
These air-bag units are concealed and mounted above the headliner where they are each secured
to one of the roof side rails (5). Each folded airbag cushion is contained within a long extruded
plastic channel (8) that extends along the roof rail from the A-pillar (6) at the front of the vehicle to
just behind the B-pillar (2) on standard cab models, and to just behind the C-pillar (2) on quad cab
models.
A long tether (7) extends down the A-pillar from the front of the airbag cushion, where it is retained
to the pillar with plastic push-in routing clips and it is secured to the base of the A-pillar near the
belt line with a screw.
The hybrid-type inflator (3) for each airbag is secured to the roof rail at the rear of the airbag unit
behind the B-pillar (standard cab) or C-pillar (quad cab), and is connected to the airbag cushion by
a long tubular manifold (4). The inflator bracket and the extruded airbag cushion channel are
located with plastic push-in fasteners to the roof rail, then secured with screws to spring nuts
located in the roof rail.
A two-wire take out of the body wire harness with a keyed and latched connector insulator (1) on
the B-pillar (standard cab) or C-pillar (quad cab) connects directly to an integral receptacle on the
inflator initiator. The body wire harness connects the airbag unit to the Airbag Control Module
(ACM).
The side curtain airbag unit cannot be adjusted or repaired and must be replaced if deployed,
faulty, or in any way damaged. Once a side curtain airbag has been deployed, the complete airbag
unit, the headliner, the upper A, B, and C-pillar trim, and all other visibly damaged components
must be replaced.
Each side curtain airbag is deployed individually by an electrical signal generated by the Airbag
Control Module (ACM) to which it is connected through left or right curtain airbag line 1 and line 2
(or squib) circuits. The hybrid-type inflator assembly for each airbag contains a small canister of
highly

compressed inert gas. When the ACM sends the proper electrical signal to the airbag inflator, the
electrical energy creates enough heat to ignite chemical pellets within the inflator.
Once ignited, these chemicals burn rapidly and produce the pressure necessary to rupture a
containment disk in the inert gas canister. The inflator and inert gas canister are sealed and
connected to a tubular manifold so that all of the released gas is directed into the folded curtain
airbag cushion, causing the cushion to inflate. As the airbag cushion inflates it will drop down from
the roof rail between the edge of the headliner and the side glass/body pillars to form a curtain-like
cushion to protect the vehicle occupants during a side impact collision.
The front tether keeps the front portion of the side curtain bag taut, thus ensuring that the bag will
deploy in the proper position. Following the airbag deployment, the airbag cushion quickly deflates
by venting the inert gas through the loose weave of the cushion fabric, and the deflated cushion
hangs down loosely from the roof rail.

Air Bag: Description and Operation Air Bag-Driver
The color-keyed, injection molded, thermoplastic driver airbag protective trim cover (2) is the most
visible part of the driver airbag. The driver airbag is located in the center of the steering wheel (1),
where it is secured with two screws to the armature of the four-spoke steering wheel. All models
have a chrome Dodge Ram emblem in the center of the trim cover. Concealed beneath the driver
airbag trim cover are the horn switch, the folded airbag cushion, the airbag cushion retainer, the
airbag housing, the airbag inflator, and the retainers that secure the inflator to the airbag housing.
The airbag cushion, housing (5), and inflator (3) are secured within an integral receptacle molded
into the back of the trim cover (4). The four vertical walls of this receptacle have a total of twelve
small windows with blocking tabs that are engaged by twelve hook formations around the perimeter
of the airbag housing. Each hook is inserted through one of the windows and the blocking tab in
each window keeps the hook properly engaged with the trim cover, locking the trim cover securely
into place on the airbag housing.
The resistive membrane-type horn switch is secured with heat stakes to the inside surface of the
driver air-bag trim cover, between the trim cover and the folded airbag cushion. The horn switch
ground pigtail wire has an eyelet terminal connector that is captured beneath a flanged nut on the
upper right inflator mounting stud on the back of the housing. The horn switch feed pigtail wire has
a black, molded plastic insulator (1) that is secured by an integral retainer in a locator hole near the
upper right corner of the airbag housing and is connected to the vehicle electrical system through a
dedicated take out and connector of the steering wheel wire harness. Both horn switch wires are
routed through an integral notch in the center of the upper edge of the airbag housing stamping.
The airbag used in this model is a multistage, Next Generation-type that complies with revised
federal airbag standards to deploy with less force than those used in some prior models. A 71
centimeter (28 inch) diameter, radial deploying fabric cushion with internal tethers is used. The
airbag inflator is a dual-initiator, non-azide, pyrotechnic-type unit with four mounting studs and is
secured to the stamped metal airbag housing by four flanged hex nuts. Two keyed and color-coded
connector receptacles on the driver airbag inflator connect the two inflator initiators to the vehicle
electrical system through two yellow-jacketed, two-wire pigtail harnesses of the clockspring.
The driver airbag unit cannot be repaired, and must be replaced if deployed or in any way
damaged. The driver airbag trim cover and horn switch unit

may be disassembled from the driver airbag unit, and is available for separate service replacement.
The multistage driver airbag is deployed by electrical signals generated by the Airbag Control
Module (ACM) through the driver airbag squib 1 and squib 2 circuits to the two initiators in the
airbag inflator. By using two initiators, the airbag can be deployed at multiple levels of force. The
force level is controlled by the ACM to suit the monitored impact conditions by providing one of
three delay intervals between the electrical signals provided to the two initiators. The longer the
delay between these signals, the less forcefully the airbag will deploy.
When the ACM sends the proper electrical signals to each initiator, the electrical energy generates
enough heat to initiate a small pyrotechnic charge which, in turn ignites chemical pellets within the
inflator. Once ignited, these chemical pellets burn rapidly and produce a large quantity of inert gas.
The inflator is sealed to the back of the airbag housing and a diffuser in the inflator directs all of the
inert gas into the airbag cushion, causing the cushion to inflate. As the cushion inflates, the driver
airbag trim cover will split at predetermined breakout lines, then fold back out of the way along with
the horn switch unit. Following an airbag deployment, the airbag cushion quickly deflates by
venting the inert gas towards the instrument panel through vent holes within the fabric used to
construct the back (steering wheel side) panel of the airbag cushion.
Some of the chemicals used to create the inert gas may be considered hazardous while in their
solid state before they are burned, but they are securely sealed within the airbag inflator. Typically,
both initiators are used and all potentially hazardous chemicals are burned during an airbag
deployment event. However, it is possible for only one initiator to be used during a deployment due
to an airbag system fault; therefore, it is necessary to always confirm that both initiators have been
used in order to avoid the improper disposal of potentially live pyrotechnic or hazardous materials.
The inert gas that is produced when the chemicals are burned is harmless. However, a small
amount of residue from the burned chemicals may cause some temporary discomfort if it contacts
the skin, eyes, or breathing passages. If skin or eye irritation is noted, rinse the affected area with
plenty of cool, clean water. If breathing passages are irritated, move to another area where there is
plenty of clean, fresh air to breath. If the irritation is not alleviated by these actions, contact a
physician.

Air Bag: Description and Operation Air Bag-Passenger
The rearward facing surface of the injection molded, thermoplastic passenger airbag door (1) is the
most visible part of the passenger airbag. The passenger airbag door is located above the glove
box opening on the instrument panel in front of the front seat passenger seating position.
SRT-10 models also have a unique instrument panel trim bezel (3) with the SRT-10 logo secured
to the lower edge of the airbag door (1).
The upper and outboard edges of the airbag door (1) are secured with seven integral snap features
(3) to the instrument panel base trim, while two screws secure the integral inboard mounting flange
to the base trim, and four screws secure the lower mounting flange to the upper glove box opening

reinforcement integral to the instrument panel structural support. The passenger airbag door
includes an air conditioning panel outlet and housing (2). The panel outlet housing features four
snap features that secure it to the back of the airbag door and a mounting tab that is also secured
with one screw to the upper glove box opening reinforcement.
Located behind the passenger airbag door within the instrument panel is the passenger airbag unit.
The passenger airbag housing (8) fits into a molded receptacle on the back of the airbag door,
where six stamped hook formations on the upper and lower edges of the airbag housing are
engaged in six small window openings on the upper and lower flanges of the receptacle to secure
the airbag door to the airbag housing. The inboard airbag door fasteners and mounting flange are
concealed beneath the instrument panel center bezel, while the lower fasteners and mounting
flange are concealed beneath the instrument panel lower surround. The passenger airbag unit is
secured by four screws through two front (7) and two rear (4) brackets integral to the base of the
airbag housing to the instrument panel structural support.
The passenger airbag unit used in this model is a multistage, Next Generation-type that complies
with revised federal airbag standards to deploy with less force than those used in some prior
models. The passenger airbag unit consists of a stamped and welded metal housing, the airbag
cushion, the airbag inflator initiators (6), and a stamped metal airbag and inflator retainer plate that
is secured to the airbag housing with six studs and nuts. The airbag housing contains the airbag
inflator and the folded airbag cushion. An approximately 80 centimeter (31.5 inch) wide by 90
centimeter (35.5 inch) high rectangular fabric cushion is used.
The airbag inflator is a non-azide, pyrotechnic-type unit that is secured to and sealed within the
airbag housing. A short four-wire pigtail harness with a keyed, yellow connector insulator (5)
connects the two inflator initiators to the vehicle electrical system through a dedicated take out and
connector of the instrument panel wire harness.
The passenger airbag includes the airbag door, the panel outlet housing and for SRT-10 models
only, the instrument panel trim bezel. This unit cannot be repaired, and must be replaced if
deployed, faulty, or in any way damaged.
The multistage passenger airbag is deployed by electrical signals generated by the Airbag Control
Module (ACM) through the passenger airbag squib 1 and squib 2 circuits to the two initiators in the
airbag inflator. By using two initiators, the airbag can be deployed at multiple levels of force. The
force level is controlled by the ACM to suit the monitored impact conditions by providing one of four
delay intervals between the electrical signals provided to the two initiators. The longer the delay
between these signals, the less forcefully the airbag will deploy.
When the ACM sends the proper electrical signals to each initiator, the electrical energy generates
enough heat to initiate a small pyrotechnic charge which, in turn ignites chemical pellets within the
inflator. Once ignited, these chemical pellets burn rapidly and produce a large quantity of inert gas.
The inflator is sealed to the airbag cushion and a diffuser in the inflator directs all of the inert gas
into the airbag cushion, causing the cushion to inflate. As the cushion inflates, the passenger
airbag door will split at predetermined tear seam lines concealed on the inside surface of the door,
then the door will pivot up over the top of the instrument panel and out of the way. Following an
airbag deployment, the airbag cushion quickly deflates by venting the inert gas through vent holes
within the fabric used to construct the back (instrument panel side) of the airbag cushion.
Typically, both initiators are used during an airbag deployment event. However, it is possible for
only one initiator to be used during a deployment due to an airbag system fault; therefore, it is
necessary to always confirm that both initiators have been used in order to avoid the improper
disposal of potentially live pyrotechnic materials.

Air Bag: Service and Repair Airbag Squib Status
Multistage airbags with multiple initiators (squibs) must be checked to determine that all squibs
were used during the deployment event. The driver and passenger airbags in this model are
deployed by electrical signals generated by the Airbag Control Module (ACM) through the driver or
passenger squib 1 and squib 2 circuits to the two initiators in the airbag inflators. Typically, both
initiators are used and all potentially hazardous chemicals are burned during an airbag deployment
event. However, it is possible for only one initiator to be used due to an airbag system fault;
therefore, it is always necessary to confirm that both initiators have been used in order to avoid the
improper handling or disposal of potentially live pyrotechnic or hazardous materials. The following
procedure should be performed using a diagnostic scan tool to verify the status of both airbag
squibs before either deployed airbag is removed from the vehicle for disposal.
CAUTION: Deployed front airbags having two initiators (squibs) in the airbag inflator may or may
not have live pyrotechnic material within the inflator. Do not dispose of these airbags unless you
are sure of complete deployment. Refer to the Hazardous Substance Control System for proper
disposal procedures. Dispose of all non-deployed and deployed airbags and seat belt tensioners in
a manner consistent with state, provincial, local, and federal regulations.
1. Be certain that the diagnostic scan tool contains the latest version of the proper diagnostic
software. Connect the scan tool to the 16-way Data Link
Connector (DLC). The DLC is located on the driver side lower edge of the instrument panel,
outboard of the steering column.
2. Turn the ignition switch to the On position. 3. Using the scan tool, read and record the active
(current) Diagnostic Trouble Code (DTC) data.
Using the active DTC information, refer to the Airbag Squib Status table to determine the status of
both driver and/or passenger airbag squibs.
NOTE: If none of the Driver or Passenger Squib 1 or 2 open are active codes, the status of the
airbag squibs is unknown. In this case the airbag should be handled and disposed of as if the
squibs were both live.

Air Bag: Service and Repair Cleanup Procedure
Following a supplemental restraint deployment, the vehicle interior will contain a powdery residue.
This residue consists primarily of harmless paniculate by-products of the small pyrotechnic charge
that initiates the propellant used to deploy a supplemental restraint. However, this residue may also
contain traces of sodium hydroxide powder, a chemical by-product of the propellant material that is
used to generate the inert gas that inflates the airbag. Since sodium hydroxide powder can irritate
the skin, eyes, nose, or throat, be certain to wear safety glasses, rubber gloves, and a long-sleeved
shirt during cleanup.
WARNING: TO AVOID PERSONAL INJURY OR DEATH, IF YOU EXPERIENCE SKIN
IRRITATION DURING CLEANUP, RUN COOL WATER OVER THE AFFECTED AREA. ALSO, IF
YOU EXPERIENCE IRRITATION OF THE NOSE OR THROAT, EXIT THE VEHICLE FOR FRESH
AIR UNTIL THE IRRITATION CEASES. IF IRRITATION CONTINUES, SEE A PHYSICIAN.
1. Begin the cleanup by using a vacuum cleaner to remove any residual powder from the vehicle
interior. Clean from outside the vehicle and work
your way inside, so that you avoid kneeling or sitting on a non-cleaned area.
2. Be certain to vacuum the heater and air conditioning outlets as well. Run the heater and air
conditioner blower on the lowest speed setting and
vacuum any powder expelled from the outlets.
CAUTION: Deployed front airbags having two initiators (squibs) in the airbag inflator may or may
not have live pyrotechnic material within the inflator. Do not dispose of these airbags unless you
are sure of complete deployment. Refer to AIRBAG SQUIB STATUS. All damaged, faulty, or
non-deployed supplemental restraints which are replaced on vehicles are to be handled and
disposed of properly. If an airbag or seat belt tensioner unit is faulty or damaged and non-deployed,
refer to the Hazardous Substance Control System for proper disposal. Be certain to dispose of all
non-deployed and deployed supplemental restraints in a manner consistent with state, provincial,
local and federal regulations.
3. Next, remove the deployed supplemental restraints from the vehicle. 4. You may need to
vacuum the interior of the vehicle a second time to recover all of the powder.

Air Bag Control Module: Description and Operation
The Airbag Control Module (ACM) (1) is also sometimes referred to as the Occupant Restraint
Controller (ORC). The ACM is located below the instrument panel center stack in the passenger
compartment of the vehicle, where it is secured by three screws to a stamped steel mounting
bracket welded onto the top of the floor panel transmission tunnel just forward of the instrument
panel center support bracket. Concealed within a hollow in the center of the die cast aluminum
ACM housing is the electronic circuitry of the ACM which includes a microprocessor, an electronic
impact sensor, an electronic sating sensor, and an energy storage capacitor. A stamped metal
cover plate is secured to the bottom of the ACM housing with four screws to enclose and protect
the internal electronic circuitry and components.
An arrow (2) printed on the label (3) on the top of the ACM housing provides a visual verification of
the proper orientation of the unit, and should always be pointed toward the front of the vehicle. The
ACM housing has integral mounting flanges on three corners. The mounting flange to the left of the
connector receptacle has an integral locating pin on its lower surface. Both left side flanges have
round mounting holes, while the flange on the right side has a slotted mounting hole. A molded
plastic electrical connector (4) with two receptacles, one containing twenty-four terminal pins and
the other containing thirty-two terminal pins, exits the rearward facing side of the ACM housing.
These terminal pins connect the ACM to the vehicle electrical system through two dedicated take
outs and connectors of the instrument panel wire harness.
The impact sensor and sating sensor internal to the ACM are calibrated for the specific vehicle, and
are only serviced as a unit with the ACM. In addition, there are unique versions of the ACM for light
and heavy-duty models, and for vehicles with or without the optional side curtain airbags. The ACM
cannot be repaired or adjusted and, if damaged or faulty, it must be replaced.
The microprocessor in the Airbag Control Module (ACM) contains the supplemental restraint
system logic circuits and controls all of the supplemental restraint system components. The ACM
uses On-Board Diagnostics (OBD) and can communicate with other electronic modules in the
vehicle as well as with the diagnostic scan tool using the Programmable Communications Interface
(PCI) data bus network. This method of communication is used for control of the airbag indicator in
the ElectroMechanical Instrument Cluster (EMIC) and for supplemental restraint system diagnosis
and testing through the 16-way data link connector located on the driver side lower edge of the
instrument panel.
The ACM microprocessor continuously monitors all of the supplemental restraint system electrical
circuits to determine the system readiness. If the ACM detects a monitored system fault, it sets an
active and stored Diagnostic Trouble Code (DTC) and sends electronic messages to the EMIC
over the PCI data bus to turn on the airbag indicator. An active fault only remains for the duration of
the fault, or in some cases for the duration of the current ignition switch cycle, while a stored fault
causes a DTC to be stored in memory by the ACM. For some DTCs, if a fault does not recur for a
number of ignition cycles, the ACM will automatically erase the stored DTC. For other internal
faults, the stored DTC is latched forever.
In standard cab models, the ACM also monitors a resistor multiplexed input from the passenger
airbag on/off switch and provides a control output for the Off indicator in the switch through a
passenger airbag indicator driver circuit. If the passenger airbag on/off switch is set to the Off
position, the ACM turns on the passenger airbag on/off switch Off indicator and will internally
disable the passenger airbag from being deployed. The ACM also turns on the on/off switch Off
indicator for about seven seconds each time the ignition switch is turned to the On position as a
bulb test. Following the bulb test, the ACM controls the status of the Off indicator based upon the
resistance of the input from the on/off switch. The ACM will also set and/or store a DTC for faults it
detects in the passenger airbag on/off switch circuits, and will turn on the airbag indicator in the
EMIC if a fault has been detected.
The ACM receives battery current through two circuits; a fused ignition switch output (run) circuit
through a fuse in the Integrated Power Module (IPM), and a fused ignition switch output (run-start)
circuit through a second fuse in the IPM. The ACM receives ground through a ground circuit and
take out of the instrument panel wire harness. This take out has a single eyelet terminal connector
that is secured by a ground screw to the instrument panel structural support. These connections
allow the ACM to be operational whenever the ignition switch is in the Start or On positions.
The ACM also contains an energy-storage capacitor. When the ignition switch is in the Start or On
positions, this capacitor is continually being charged with enough electrical energy to deploy the
supplemental restraint components for up to one second following a battery disconnect or failure.
The purpose of the capacitor is to provide backup supplemental restraint system protection in case
there is a loss of battery current supply to the ACM during an impact.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag Control Module > Component Information >
Locations > Page 6269
Two sensors are contained within the ACM, an electronic impact sensor and a safing sensor. The
electronic impact sensors are accelerometers that sense the rate of vehicle deceleration, which
provide verification of the direction and severity of an impact. On models equipped with optional
side curtain airbags, the ACM also monitors inputs from two remote side impact sensors located
within both the left and right B-pillars to control deployment of the side curtain airbag units.
The safing sensor is an electronic accelerometer sensor within the ACM that provides an additional
logic input to the ACM microprocessor. The safing sensor is used to verify the need for a
supplemental restraint deployment by detecting impact energy of a lesser magnitude than that of
the primary electronic impact sensors, and must exceed a safing threshold in order for the airbags
to deploy. Vehicles equipped with optional side curtain airbags feature a second safing sensor
within the ACM to provide confirmation to the ACM microprocessor of side impact forces. This
second safing sensor is a bi-directional unit that detects impact forces from either side of the
vehicle.
Pre-programmed decision algorithms in the ACM microprocessor determine when the deceleration
rate as signaled by the impact sensors and the safing sensors indicate an impact that is severe
enough to require supplemental restraint system protection and, based upon the severity of the
monitored impact and the status of the passenger airbag on/off switch input, determines the level of
front airbag deployment force required for each front seating position. When the programmed
conditions are met, the ACM sends the proper electrical signals to deploy the dual multistage front
airbags at the programmed force levels, the front seat belt tensioners and, if the vehicle is so
equipped, either side curtain airbag unit. For vehicles equipped with the passenger airbag on/off
switch, the passenger front airbag and seat belt tensioner will be deployed by the ACM only if
enabled by the switch (passenger airbag on/off switch indicator Off) at the time of the impact.
The hard wired inputs and outputs for the ACM may be diagnosed and tested using conventional
diagnostic tools and methods. However, conventional diagnostic methods will not prove conclusive
in the diagnosis of the ACM, the PCI data bus network, or the electronic message inputs to and
outputs from the ACM. The most reliable, efficient, and accurate means to diagnose the ACM, the
PCI data bus, and the electronic message inputs to and outputs from the ACM requires the use of
a diagnostic scan tool.

Air Bag Deactivation Switch: Description and Operation
The passenger airbag on/off switch (1) is standard equipment on all standard cab versions of this
model when they are equipped with the dual front airbag system. This switch is a two-position,
resistor multiplexed switch with a single integral red Light-Emitting Diode (LED), and a non-coded
key cylinder-type actuator. The switch is located in the lower right corner of instrument panel center
bezel, near the center of instrument panel to make the Off indicator (3) visible to all front seat
occupants.
When the switch is in its installed position, the only components visible through the dedicated
opening of the cluster bezel are the switch face plate (2) and nomenclature, and the key cylinder
actuator (4). The "Off" position of the switch is illuminated when this switch position is selected,
while the "On" position of the switch is designated by text imprinted upon the face plate of the
switch, but is not illuminated. The remainder of the switch is concealed behind the switch face plate
and the instrument panel center bezel.
The passenger airbag on/off switch housing is constructed of molded plastic and has three integral
mounting tabs. These mounting tabs are used to secure the switch to the back of the molded
plastic switch face plate with three small screws. The molded plastic face plate also has three
integral mounting tabs that are used to secure the switch and face plate unit to the instrument
panel center bezel with three additional screws.
A molded plastic connector receptacle on the back of the switch housing connects the switch to the
vehicle electrical system through a dedicated take out and connector of the instrument panel wire
harness. The molded plastic harness connector insulator is keyed and latched to ensure proper
and secure switch electrical connections. The passenger airbag on/off switch cannot be adjusted or
repaired and, if faulty or damaged, the switch must be replaced.
The passenger airbag on/off switch allows the customer to turn the passenger airbag function On
or Off to accommodate certain uses of the right front seating position where airbag protection may
not be desired. See the vehicle glove box for specific recommendations on when to enable or
disable the passenger airbag. The Off indicator of the switch will be illuminated whenever the
switch is turned to the Off position and the ignition switch is in the On position.
The ignition key is the only key or object that should ever be inserted into the key cylinder actuator
of the switch. The on/off switch requires only a partial key insertion to fully depress a spring-loaded
locking plunger. The spring-loaded locking plunger prevents the user from leaving the key in the
switch. The key will be automatically ejected when force is not applied. To actuate the passenger
airbag on/off switch, insert the ignition key into the switch key actuator far enough to fully depress
the plunger, then rotate the actuator to the desired switch position.
When the switch key actuator is rotated to its clockwise stop (the key actuator slot will be aligned
with the Off indicator), the Off indicator is illuminated and the passenger airbag is disabled. When
the switch is rotated to its counterclockwise stop (the key actuator slot will be in a vertical position),
the Off indicator will be extinguished and the passenger airbag is enabled.
The passenger airbag on/off switch connects one of two internal resistors in series between the
passenger airbag mux switch sense and passenger airbag mux switch return circuits of the Airbag
Control Module (ACM). The ACM continually monitors the resistance in these circuits to determine
the switch position that has been selected.
When the switch is in the Off position, the ACM provides a ground input to the switch through the
passenger airbag indicator driver circuit, which energizes the Light-Emitting Diode (LED) that
illuminates the Off indicator of the switch. The ACM will also illuminate the Off indicator of the
switch for about seven seconds each time the ignition switch is turned to the On position as a bulb
test.
The ACM will store a Diagnostic Trouble Code (DTC) for any fault it detects in the passenger
airbag on/off switch or Off indicator circuits, and will illuminate the airbag indicator in the instrument
cluster if a fault is detected. For proper diagnosis of the passenger airbag on/off switch or the ACM,
a diagnostic scan tool is required.

Clockspring Assembly / Spiral Cable: Description and Operation
The clockspring assembly is secured with two screws onto the multi-function switch mounting
housing near the top of the steering column behind the steering wheel. The clockspring consists of
a flat, round molded plastic case (8) with a stubby tail that hangs below the steering column. The
tail contains two connector receptacles that face toward the instrument panel. Within the plastic
case is a spool-like molded plastic rotor (10) with a large exposed hub. The upper surface of the
rotor hub has a large center hole, two large flats, an engagement dowel with a yellow rubber boot
(7), two short pigtail wires with connectors (1), and two connector receptacles (5) that face toward
the steering wheel.
The lower surface of the rotor hub has a molded plastic turn signal cancel cam (3) with two lobes
that is keyed to the rotor and is secured there with four integral snap features. Within the plastic
case and wound around the rotor spool is a long ribbon-like tape that consists of several thin
copper wire leads sandwiched between two thin plastic membranes. The outer end of the tape
terminates at the connector receptacles (4) that face the instrument panel, while the inner end of
the tape terminates at the pigtail wires and connector receptacles on the hub of the clockspring
rotor that face the steering wheel.
Service replacement clocksprings are shipped pre-centered and with a molded plastic locking pin
(1) that snaps into a receptacle on the rotor and is engaged between two tabs on the upper surface
of the rotor case. The locking pin secures the centered clockspring rotor to the clockspring case
during shipment and handling, but must be removed from the clockspring after it is installed on the
steering column.
The clockspring cannot be repaired. If the clockspring is faulty, damaged, or if the driver airbag has
been deployed, the clockspring must be replaced.
The clockspring is a mechanical electrical circuit component that is used to provide continuous
electrical continuity between the fixed instrument panel wire harness and the electrical components
mounted on or in the rotating steering wheel. On this model the rotating electrical components
include the driver airbag, the horn switch, the speed control switches, and the remote radio
switches, if the vehicle is so equipped. The clockspring case is positioned and secured to the
multi-function switch mounting housing near the top of the steering column. The connector
receptacles on the tail of the fixed clockspring case connect the clockspring to the vehicle electrical
system through two take outs with connectors from the instrument panel wire harness.
The clockspring rotor is movable and is keyed by an engagement dowel that is molded onto the
rotor hub between two fins that are cast into the lower surface of the steering wheel armature. A
yellow rubber boot is installed over the engagement dowel to eliminate contact noise between the
dowel and the steering wheel. The two lobes on the turn signal cancel cam on the lower surface of
the clockspring rotor hub contact a turn signal cancel actuator of the multi-function switch to
provide automatic turn signal cancellation.

Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Clockspring Assembly / Spiral Cable, Air Bag >
Component Information > Diagrams > Page 6287
Two short, yellow-sleeved pigtail wires on the upper surface of the clockspring rotor connect the
clockspring to the driver airbag, while a steering wheel wire harness connects the two connector
receptacles on the upper surface of the clockspring rotor to the horn switch feed pigtail wire
connector and, if the vehicle is so equipped, to the optional speed control and remote radio
switches on the steering wheel.
Like the clockspring in a timepiece, the clockspring tape has travel limits and can be damaged by
being wound too tightly during full stop-to-stop steering wheel rotation. To prevent this from
occurring, the clockspring is centered when it is installed on the steering column. Centering the
clockspring indexes the clockspring tape to the movable steering components so that the tape can
operate within its designed travel limits. However, if the clockspring is removed from the steering
column or if the steering shaft is disconnected from the steering gear, the clockspring spool can
change position relative to the movable steering components. The clockspring must be re-centered
following completion of this service or the tape may be damaged.
Service replacement clocksprings are shipped pre-centered and with a plastic locking pin installed.
This locking pin should not be removed until the clockspring has been installed on the steering
column. If the locking pin is removed before the clockspring is installed on a steering column, the
clockspring centering procedure must be performed.

Impact Sensor: Description and Operation
Two side impact sensors (1) are used on this model when it is equipped with the optional side
curtain air-bags, one each for the left and right sides of the vehicle. These sensors are mounted
remotely from the bi-directional safing sensor that is internal to the Air-bag Control Module (ACM).
Each side impact sensor is secured with a nut within the right or left B-pillar just above the front
seat belt retractors and behind the lower B-pillar trim within the passenger compartment. The
sensor housing has an integral connector receptacle (2), an integral mounting stud (3), and an
integral anti-rotation pin.
The right and left side impact sensors are identical in construction and calibration. A cavity in the
center of the molded black plastic impact sensor housing contains the electronic circuitry of the
sensor which includes an electronic communication chip and an electronic impact sensor. Potting
material fills the cavity to seal and protect the internal electronic circuitry and components. The side
impact sensors are each connected to the vehicle electrical system through a dedicated take out
and connector of the body wire harness.
The side impact sensors cannot be repaired or adjusted and, if damaged or faulty, they must be
replaced.
The side impact sensors are electronic accelerometers that sense the rate of vehicle deceleration,
which provides verification of the direction and severity of an impact. Each sensor also contains an
electronic communication chip that allows the unit to communicate the sensor status as well as
sensor fault information to the microprocessor in the Airbag Control Module (ACM).
The ACM microprocessor continuously monitors all of the side passive restraint system electrical
circuits to determine the system readiness. If the ACM detects a monitored system fault, it sets a
Diagnostic Trouble Code (DTC) and controls the airbag indicator operation accordingly. The impact
sensors each receive battery current and ground through dedicated left and right sensor plus and
minus circuits from the ACM. The impact sensors and the ACM communicate by modulating the
voltage in the sensor plus circuit.
The hard wired circuits between the side impact sensors and the ACM may be diagnosed and
tested using conventional diagnostic tools and procedures. However, conventional diagnostic
methods will not prove conclusive in the diagnosis of the ACM, the impact sensors, or the
electronic message inputs to or outputs from the impact sensors. The most reliable, efficient, and
accurate means to diagnose the impact sensors, the ACM, and the electronic message
communication between the sensors and the ACM requires the use of a diagnostic scan tool.

Information > Description and Operation
Malfunction Lamp / Indicator: Description and Operation
An airbag indicator is standard equipment on all instrument clusters. However, the instrument
cluster can be programmed to disable this indicator on vehicles that are not equipped with the
airbag system, which is not available in some markets. The airbag indicator is located near the
upper edge of the instrument cluster, between the tachometer and the speedometer.
The airbag indicator consists of a stencil-like cutout of the words "AIR BAG" in the opaque layer of
the instrument cluster overlay. The dark outer layer of the overlay prevents the indicator from being
clearly visible when it is not illuminated. A red Light Emitting Diode (LED) behind the cutout in the
opaque layer of the overlay causes the "AIR BAG" text to appear in red through the translucent
outer layer of the overlay when the indicator is illuminated from behind by the LED, which is
soldered onto the instrument cluster electronic circuit board. The airbag indicator is serviced as a
unit with the instrument cluster.
The airbag indicator gives an indication to the vehicle operator when the airbag system is faulty or
inoperative. The airbag indicator is controlled by a transistor on the instrument cluster circuit board
based upon cluster programming and electronic messages received by the cluster from the Airbag
Control Module (ACM) over the Programmable Communications Interface (PCI) data bus.
The airbag indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster
logic circuit, and that logic will only allow this indicator to operate when the instrument cluster
receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the
LED will always be off when the ignition switch is in any position except On or Start. The LED only
illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument
cluster will turn on the airbag indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the airbag indicator is
illuminated for about six seconds. The entire bulb test is a function of the ACM.
- ACM Lamp-On Message - Each time the cluster receives a lamp-on message from the ACM, the
airbag indicator will be illuminated. The indicator remains illuminated for about twelve seconds or
until the cluster receives a lamp-off message from the ACM, whichever is longer.
- Communication Error - If the cluster receives no airbag messages for three consecutive seconds,
the airbag indicator is illuminated. The indicator remains illuminated until the cluster receives a
single lamp-off message from the ACM.
- Actuator Test - Each time the cluster is put through the actuator test, the airbag indicator will be
turned on, then off again during the bulb check portion of the test to confirm the functionality of the
LED and the cluster control circuitry. The actuator test illumination of the airbag indicator is a
function of the instrument cluster.
The ACM continually monitors the airbag system circuits and sensors to decide whether the system
is in good operating condition. The ACM then sends the proper lamp-on or lamp-off messages to
the instrument cluster. If the ACM sends a lamp-on message after the bulb test, it indicates that the
ACM has detected a system malfunction and/or that the airbags and seat belt tensioners may not
deploy when required, or may deploy when not required. The ACM will store a Diagnostic Trouble
Code (DTC) for any malfunction it detects. Each time the airbag indicator fails to illuminate due to
an open or short in the cluster airbag indicator circuit, the cluster sends a message notifying the
ACM of the condition, the instrument cluster and the ACM will each store a DTC, and the cluster
will flash the seatbelt indicator on and off as a backup to notify the vehicle operator.
For proper diagnosis of the airbag system, the ACM, the PCI data bus, or the electronic message
inputs to the instrument cluster that control the airbag indicator, a diagnostic scan tool is required.

Air Bag Control Module: Description and Operation
The Airbag Control Module (ACM) (1) is also sometimes referred to as the Occupant Restraint
Controller (ORC). The ACM is located below the instrument panel center stack in the passenger
compartment of the vehicle, where it is secured by three screws to a stamped steel mounting
bracket welded onto the top of the floor panel transmission tunnel just forward of the instrument
panel center support bracket. Concealed within a hollow in the center of the die cast aluminum
ACM housing is the electronic circuitry of the ACM which includes a microprocessor, an electronic
impact sensor, an electronic sating sensor, and an energy storage capacitor. A stamped metal
cover plate is secured to the bottom of the ACM housing with four screws to enclose and protect
the internal electronic circuitry and components.
An arrow (2) printed on the label (3) on the top of the ACM housing provides a visual verification of
the proper orientation of the unit, and should always be pointed toward the front of the vehicle. The
ACM housing has integral mounting flanges on three corners. The mounting flange to the left of the
connector receptacle has an integral locating pin on its lower surface. Both left side flanges have
round mounting holes, while the flange on the right side has a slotted mounting hole. A molded
plastic electrical connector (4) with two receptacles, one containing twenty-four terminal pins and
the other containing thirty-two terminal pins, exits the rearward facing side of the ACM housing.
These terminal pins connect the ACM to the vehicle electrical system through two dedicated take
outs and connectors of the instrument panel wire harness.
The impact sensor and sating sensor internal to the ACM are calibrated for the specific vehicle, and
are only serviced as a unit with the ACM. In addition, there are unique versions of the ACM for light
and heavy-duty models, and for vehicles with or without the optional side curtain airbags. The ACM
cannot be repaired or adjusted and, if damaged or faulty, it must be replaced.
The microprocessor in the Airbag Control Module (ACM) contains the supplemental restraint
system logic circuits and controls all of the supplemental restraint system components. The ACM
uses On-Board Diagnostics (OBD) and can communicate with other electronic modules in the
vehicle as well as with the diagnostic scan tool using the Programmable Communications Interface
(PCI) data bus network. This method of communication is used for control of the airbag indicator in
the ElectroMechanical Instrument Cluster (EMIC) and for supplemental restraint system diagnosis
and testing through the 16-way data link connector located on the driver side lower edge of the
instrument panel.
The ACM microprocessor continuously monitors all of the supplemental restraint system electrical
circuits to determine the system readiness. If the ACM detects a monitored system fault, it sets an
active and stored Diagnostic Trouble Code (DTC) and sends electronic messages to the EMIC
over the PCI data bus to turn on the airbag indicator. An active fault only remains for the duration of
the fault, or in some cases for the duration of the current ignition switch cycle, while a stored fault
causes a DTC to be stored in memory by the ACM. For some DTCs, if a fault does not recur for a
number of ignition cycles, the ACM will automatically erase the stored DTC. For other internal
faults, the stored DTC is latched forever.
In standard cab models, the ACM also monitors a resistor multiplexed input from the passenger
airbag on/off switch and provides a control output for the Off indicator in the switch through a
passenger airbag indicator driver circuit. If the passenger airbag on/off switch is set to the Off
position, the ACM turns on the passenger airbag on/off switch Off indicator and will internally
disable the passenger airbag from being deployed. The ACM also turns on the on/off switch Off
indicator for about seven seconds each time the ignition switch is turned to the On position as a
bulb test. Following the bulb test, the ACM controls the status of the Off indicator based upon the
resistance of the input from the on/off switch. The ACM will also set and/or store a DTC for faults it
detects in the passenger airbag on/off switch circuits, and will turn on the airbag indicator in the
EMIC if a fault has been detected.
The ACM receives battery current through two circuits; a fused ignition switch output (run) circuit
through a fuse in the Integrated Power Module (IPM), and a fused ignition switch output (run-start)
circuit through a second fuse in the IPM. The ACM receives ground through a ground circuit and
take out of the instrument panel wire harness. This take out has a single eyelet terminal connector
that is secured by a ground screw to the instrument panel structural support. These connections
allow the ACM to be operational whenever the ignition switch is in the Start or On positions.
The ACM also contains an energy-storage capacitor. When the ignition switch is in the Start or On
positions, this capacitor is continually being charged with enough electrical energy to deploy the
supplemental restraint components for up to one second following a battery disconnect or failure.
The purpose of the capacitor is to provide backup supplemental restraint system protection in case
there is a loss of battery current supply to the ACM during an impact.

Dodge Workshop Manuals > Restraint Systems > Relays and Modules - Restraint Systems > Air Bag Control Module >
Component Information > Locations > Page 6323
Two sensors are contained within the ACM, an electronic impact sensor and a safing sensor. The
electronic impact sensors are accelerometers that sense the rate of vehicle deceleration, which
provide verification of the direction and severity of an impact. On models equipped with optional
side curtain airbags, the ACM also monitors inputs from two remote side impact sensors located
within both the left and right B-pillars to control deployment of the side curtain airbag units.
The safing sensor is an electronic accelerometer sensor within the ACM that provides an additional
logic input to the ACM microprocessor. The safing sensor is used to verify the need for a
supplemental restraint deployment by detecting impact energy of a lesser magnitude than that of
the primary electronic impact sensors, and must exceed a safing threshold in order for the airbags
to deploy. Vehicles equipped with optional side curtain airbags feature a second safing sensor
within the ACM to provide confirmation to the ACM microprocessor of side impact forces. This
second safing sensor is a bi-directional unit that detects impact forces from either side of the
vehicle.
Pre-programmed decision algorithms in the ACM microprocessor determine when the deceleration
rate as signaled by the impact sensors and the safing sensors indicate an impact that is severe
enough to require supplemental restraint system protection and, based upon the severity of the
monitored impact and the status of the passenger airbag on/off switch input, determines the level of
front airbag deployment force required for each front seating position. When the programmed
conditions are met, the ACM sends the proper electrical signals to deploy the dual multistage front
airbags at the programmed force levels, the front seat belt tensioners and, if the vehicle is so
equipped, either side curtain airbag unit. For vehicles equipped with the passenger airbag on/off
switch, the passenger front airbag and seat belt tensioner will be deployed by the ACM only if
enabled by the switch (passenger airbag on/off switch indicator Off) at the time of the impact.
The hard wired inputs and outputs for the ACM may be diagnosed and tested using conventional
diagnostic tools and methods. However, conventional diagnostic methods will not prove conclusive
in the diagnosis of the ACM, the PCI data bus network, or the electronic message inputs to and
outputs from the ACM. The most reliable, efficient, and accurate means to diagnose the ACM, the
PCI data bus, and the electronic message inputs to and outputs from the ACM requires the use of
a diagnostic scan tool.

AUTOMATIC LOCKING RETRACTOR
The seat belt retractors used in all seating positions include an inertia-type, emergency locking
mechanism (7) as standard equipment. However, the retractor locking mechanism for the
passenger side front seating position is mechanically switchable from an emergency locking
retractor to an automatic locking retractor. The primary function of this feature is to securely
accommodate a child seat in the passenger side front seating position of the vehicle without the
need for a self-cinching seat belt tip half latch plate unit or another supplemental device that would
be required to prevent the seat belt webbing from unwinding freely from the retractor spool of an
inertia-type emergency locking retractor mechanism.
The automatic locking mechanism is integral to the passenger side front seat belt and retractor unit
and is concealed beneath a molded plastic cover located on the same side of the retractor spool as
the seat belt tensioner housing. The retractor is secured to the inner B-pillar on the right side of the
vehicle and is concealed beneath the molded plastic inner B-pillar trim. The automatic locking
mechanism cannot be adjusted or repaired and, if faulty or damaged, the entire passenger side
front seat belt and retractor unit must be replaced.
The automatic locking mode of the retractor is engaged and the retractor is switched from
operating as a standard inertia-type emergency locking retractor by first buckling the combination
lap and shoulder belt buckle. Then grasp the shoulder belt and pull all of the webbing out of the
retractor. Once all of the belt webbing is extracted from the spool, the retractor will automatically
become engaged in the pre-locked automatic locking mode and will make an audible clicking or
ratcheting sound as the shoulder belt is allowed to retract to confirm that the automatic locking
mode is now engaged. Once the automatic locking mode is engaged, the retractor will remain
locked and the belt will remain tight around whatever it is restraining.
The retractor is returned to standard emergency locking mode by unbuckling the combination lap
and shoulder belt buckle and allowing the belt webbing to be almost fully retracted onto the
retractor spool. The emergency locking mode is confirmed by the absence of the audible clicking or
ratcheting sound as the belt webbing retracts. This mode will allow the belt to unwind from and
wind onto the retractor spool freely unless and until a predetermined inertia load is sensed, or until
the retractor is again switched to the automatic locking mode.

Description and Operation
Seat Belt Buckle Switch: Description and Operation
The seat belt switch is a small, normally open, single pole, single throw, leaf contact, momentary
switch. Only one seat belt switch is installed in the vehicle, and it is integral to the buckle of the
driver side front seat belt buckle-half, located on the inboard side of the driver side front seat track
(4). The seat belt switch is connected to the vehicle electrical system through a two-wire pigtail wire
(3) and connector on the seat belt buckle-half (1), which is connected to a wire harness connector
and take out of the seat wire harness routed beneath the driver side front seat cushion (2) in the
passenger compartment.
The seat belt switch cannot be adjusted or repaired and, if faulty or damaged, the entire driver side
front seat belt buckle-half unit must be replaced.
The seat belt switch is designed to control a path to ground for the seat belt switch sense input of
the ElectroMechanical Instrument Cluster (EMIC). When the driver side front seat belt tip-half is
inserted into the seat belt buckle, the switch closes the path to ground; and, when the driver side
front seat belt tip-half is removed from the seat belt buckle, the switch opens the ground path. The
switch is actuated by the latch mechanism within the seat belt buckle.
The seat belt switch is connected in series between ground and the seat belt switch sense input of
the instrument cluster. The seat belt switch receives ground at all times through its pigtail wire
connection to the seat wire harness from a take out of the body wire harness. An eyelet terminal
connector on the body wire harness ground take out is secured beneath a ground screw on the left
cowl side inner panel, beneath the instrument panel. The seat belt switch may de diagnosed using
conventional diagnostic tools and methods.

Dodge Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Reminder Lamp > Component Information
> Description and Operation
Seat Belt Reminder Lamp: Description and Operation
A seatbelt indicator is standard equipment on all instrument clusters. The seatbelt indicator is
located near the upper edge of the instrument cluster, between the tachometer and the
speedometer.
The seatbelt indicator consists of a stencil-like cutout of the International Control and Display
Symbol icon for "Seat Belt" in the opaque layer of the instrument cluster overlay. The dark outer
layer of the overlay prevents the indicator from being clearly visible when it is not illuminated. A red
Light Emitting Diode (LED) behind the cutout in the opaque layer of the overlay causes the icon to
appear in red through the translucent outer layer of the overlay when the indicator is illuminated
from behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The
seatbelt indicator is serviced as a unit with the instrument cluster.
The seatbelt indicator gives an indication to the vehicle operator of the status of the driver side front
seatbelt. This indicator is controlled by a transistor on the instrument cluster circuit board based
upon cluster programming and a hard wired input from the seatbelt switch in the driver side front
seatbelt buckle through the seat belt indicator driver circuit.
The seatbelt indicator also includes a programmable enhanced seatbelt reminder or "beltminder"
feature that is enabled when the vehicle is shipped from the factory. This beltminder feature can be
disabled and enabled by the customer using a specific programming event sequence, or by the
dealer using a diagnostic scan tool.
The seatbelt indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster
logic circuit, and that logic will only allow this indicator to operate when the instrument cluster
receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the
LED will always be off when the ignition switch is in any position except On or Start. The LED only
illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument
cluster will turn on the seatbelt indicator for the following reasons:
- Seatbelt Reminder Function - Each time the cluster receives a battery current input on the fused
ignition switch output (run-start) circuit, the indicator will be illuminated as a seatbelt reminder for
about six seconds, or until the ignition switch is turned to the Off position, whichever occurs first.
This reminder function will occur regardless of the status of the seatbelt switch input to the cluster.
- Driver Side Front Seatbelt Not Buckled - Beltminder Active - Following the seatbelt reminder
function, each time the cluster detects an open circuit on the seat belt indicator driver circuit
(seatbelt switch open = seatbelt unbuckled) with the ignition switch in the Start or On positions, the
indicator will be illuminated. In addition, if the driver side front seat belt remains unbuckled about
sixty seconds after the conclusion of the seatbelt reminder function with the vehicle speed greater
than about 13 kilometers-per-hour (8 miles-per-hour), the seatbelt indicator will begin to cycle
between flashing on and off for five seconds, then lighting solid for three seconds. The seatbelt
indicator will continue to cycle between flashing and solid illumination for twelve complete cycles,
until the seat belt indicator driver input to the cluster is closed to ground (seatbelt switch closed =
seatbelt buckled), or until the ignition switch is turned to the Off position, whichever occurs first.
- Driver Side Front Seatbelt Not Buckled - Beltminder Inactive - Following the seatbelt reminder
function, each time the cluster detects an open circuit on the seat belt indicator driver circuit
(seatbelt switch open = seatbelt unbuckled) with the ignition switch in the Start or On positions, the
indicator will be illuminated. The seatbelt indicator remains illuminated until the seat belt indicator
driver input to the cluster is closed to ground (seatbelt switch closed = seatbelt buckled), or until the
ignition switch is turned to the Off position, whichever occurs first.
- Airbag Indicator Backup - If the instrument cluster detects a fault in the airbag indicator circuit it
will send a message indicating the fault to the Airbag Control Module (ACM), store a Diagnostic
Trouble Code (DTC) in the cluster memory, then flash the seatbelt indicator on and off. The cluster
will continue to flash the seatbelt indicator until the airbag indicator circuit fault is resolved, or until
the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the seatbelt indicator will be
turned on, then off again during the bulb check portion of the test to confirm the functionality of the
LED and the cluster control circuitry.

Description and Operation
Seat Belt Retractor: Description and Operation
AUTOMATIC LOCKING RETRACTOR
The seat belt retractors used in all seating positions include an inertia-type, emergency locking
mechanism (7) as standard equipment. However, the retractor locking mechanism for the
passenger side front seating position is mechanically switchable from an emergency locking
retractor to an automatic locking retractor. The primary function of this feature is to securely
accommodate a child seat in the passenger side front seating position of the vehicle without the
need for a self-cinching seat belt tip half latch plate unit or another supplemental device that would
be required to prevent the seat belt webbing from unwinding freely from the retractor spool of an
inertia-type emergency locking retractor mechanism.
The automatic locking mechanism is integral to the passenger side front seat belt and retractor unit
and is concealed beneath a molded plastic cover located on the same side of the retractor spool as
the seat belt tensioner housing. The retractor is secured to the inner B-pillar on the right side of the
vehicle and is concealed beneath the molded plastic inner B-pillar trim. The automatic locking
mechanism cannot be adjusted or repaired and, if faulty or damaged, the entire passenger side
front seat belt and retractor unit must be replaced.
The automatic locking mode of the retractor is engaged and the retractor is switched from
operating as a standard inertia-type emergency locking retractor by first buckling the combination
lap and shoulder belt buckle. Then grasp the shoulder belt and pull all of the webbing out of the
retractor. Once all of the belt webbing is extracted from the spool, the retractor will automatically
become engaged in the pre-locked automatic locking mode and will make an audible clicking or
ratcheting sound as the shoulder belt is allowed to retract to confirm that the automatic locking
mode is now engaged. Once the automatic locking mode is engaged, the retractor will remain
locked and the belt will remain tight around whatever it is restraining.
The retractor is returned to standard emergency locking mode by unbuckling the combination lap
and shoulder belt buckle and allowing the belt webbing to be almost fully retracted onto the
retractor spool. The emergency locking mode is confirmed by the absence of the audible clicking or
ratcheting sound as the belt webbing retracts. This mode will allow the belt to unwind from and
wind onto the retractor spool freely unless and until a predetermined inertia load is sensed, or until
the retractor is again switched to the automatic locking mode.

Seat Belt Tensioner: Description and Operation Seat Belt Tension Reducer
A seat belt tension reducer (5) is standard equipment for the driver side front outboard seat belt on
standard cab versions of this model. The tension reducer is integral to the driver side front outboard
seat belt and retractor unit, which is secured to the inner B-pillar on the left side of the vehicle. The
retractor is concealed beneath the molded plastic inner B-pillar trim.
The seat belt tension reducer consists primarily of a 12-volt Direct Current (DC) solenoid and an
integral connector receptacle (6) that is located on the forward facing end housing of the retractor.
The seat belt tension reducer is controlled by a battery current output of the ignition switch and a
ground path provided by the seat belt switch, and is connected to the vehicle electrical system
through a dedicated take out of the body wire harness by a keyed and latching molded plastic
connector insulator to ensure a secure connection.
The seat belt tension reducer cannot be repaired and, if faulty or damaged, the entire driver side
front outboard seat belt and retractor unit must be replaced.
The seat belt tension reducer is controlled by a ground signal received from the seat belt switch on
the seat belt switch sense circuit and a battery current signal received from the ignition switch on
the fused ignition switch output (run-accessory) circuit. When the seat belt switch is closed (the
driver side front seat belt is fastened) and the ignition switch is in the On or Accessory positions,
the seat belt tension reducer solenoid is energized.
When the solenoid is energized, it actuates a mechanism within the driver side front outboard seat
belt retractor to reduce the normal recoil spring tension exerted by the retractor spool, which is
designed to reel in the seat belt webbing onto the spool. When the driver side seat belt is
unbuckled or if the ignition switch is turned to any position except On or Accessory, the tension
reducer solenoid is de-energized and the normal recoil spring tension of the retractor is restored.
The action of the seat belt tension reducer results in improved seat belt comfort for the driver.
Reducing the seat belt retractor recoil spring tension is desirable on standard cab models of this
vehicle and not on the quad cab model due to the different mounting position required for the seat
belt turning loop on the B-pillar relative to the driver's seat position on the standard cab model. The
seat belt tension reducer may be diagnosed using conventional diagnostic tools and methods.

Seat Belt Tensioner: Description and Operation Seat Belt Tensioner
Front outboard seating position seat belt tensioners supplement the driver and passenger airbags
for all versions of this model. The seat belt tensioner is integral to the front outboard seat belt and
retractor units, which are secured to the inner B-pillar on the right and left sides of the vehicle. The
retractor is concealed beneath the molded plastic inner B-pillar trim.
The seat belt tensioner consists primarily of a die cast aluminum tensioner housing or chamber (1),
a mechanical clutch unit, a tape-like metal strip, a pair of cutters, a pyrotechnically activated gas
generator (2), and a short pigtail wire (3). All of these components are located on one side of the
retractor spool on the outside of the retractor housing. The seat belt tensioners are controlled by
the Airbag Control Module (ACM) and are connected to the vehicle electrical system through a
dedicated take out of the body wire harness by a keyed and latching molded plastic connector
insulator to ensure a secure connection.
The seat belt tensioners cannot be repaired and, if faulty or damaged, the entire outboard front
seat belt and retractor unit must be replaced. If the front airbags have been deployed, the seat belt
tensioners have also been deployed. The seat belt tensioners are not intended for reuse and must
be replaced following any front airbag deployment. A locked retractor that will not allow the seat
belt webbing to be retracted or extracted is a sure indication that the seat belt tensioner has been
deployed and requires replacement.
The seat belt tensioners are deployed in conjunction with the dual front airbags by a signal
generated by the Airbag Control Module (ACM) through the driver or passenger seat belt tensioner
line 1 and line 2 (or squib) circuits. When the ACM sends the proper electrical signal to the
tensioners, the electrical energy generates enough heat to initiate a small pyrotechnic gas
generator.
The gas generator is installed at the top of the tensioner housing which contains a long metal tape
that is routed through two chambers within the housing. Each end of the tape is wound around the
outer sleeve of a mechanical clutch mechanism secured to one end of the torsion bar upon which
the retractor spool is secured. As the gas expands, it is directed against the metal tape within the
two chambers of the housing causing the tape to unwind from the clutch sleeve. As the clutch
rotates it engages the torsion bar, which drives the seat belt retractor spool causing the slack to be
removed from the seat belt.
Once a seat belt tensioning sequence has been completed, the forward momentum of the
occupant results in deformation of the torsion bar. As the torsion bar deforms it allows the seat belt
webbing to unwind from the retractor spool, which causes the metal tape to be wound back onto
the clutch sleeve until it is pulled tight against two cutter blades within the housing, which
immediately cut the metal tape.
Removing excess slack from the seat belt not only keeps the occupant properly positioned for an
airbag deployment following a frontal impact of the vehicle, but also helps to reduce injuries that the
occupant might experience in these situations as a result of a harmful contact with the steering
wheel, steering column, instrument panel and/or windshield. Also, the torsion bar is designed to
deform in order to control the loading being applied to the occupant by the seat belt during a frontal
impact, further reducing the potential for occupant injuries.
The ACM monitors the condition of the seat belt tensioners through circuit resistance, and will
illuminate the airbag indicator in the ElectroMechanical Instrument Cluster (EMIC) and store a
Diagnostic Trouble Code (DTC) for any fault that is detected. For proper diagnosis of the seat belt
tensioners, a diagnostic scan tool is required.

WARNING: TO AVOID PERSONAL INJURY OR DEATH, ON VEHICLES EQUIPPED WITH
AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY
STEERING WHEEL, STEERING COLUMN, AIRBAG, SEAT BELT TENSIONER, IMPACT
SENSOR, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT
AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR
THE SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS
OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE SUPPLEMENTAL RESTRAINT
SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT.
1. Disconnect and isolate the battery negative cable. Disconnect the body wire harness connector
for the seat belt tension reducer from the tension
reducer connector receptacle on the driver side front outboard seat belt and retractor unit. Using an
ohmmeter, measure the resistance between the seat belt switch sense circuit terminal pin and the
fused ignition switch output (run-accessory) circuit terminal pin in the tension reducer connector
receptacle on the retractor. Resistance through the tension reducer solenoid coil should be 53
ohms at 20° C (68° F). If OK, go to Step 2. If not OK, replace the faulty driver side front outboard
seat belt and retractor unit.
2. Check for continuity between the seat belt switch sense circuit cavity of the body wire harness
connector for the seat belt tension reducer and a
good ground. There should be continuity with the driver side front seat belt buckled, and no
continuity with the driver side front seat belt unbuckled. If OK, go to Step 3. If not OK, repair the
shorted or open seat belt switch sense circuit between the tension reducer and the seat belt switch
as required.
3. Reconnect the battery negative cable. Check for battery current at the fused ignition switch
output (run-accessory) circuit of the body wire harness
connector for the seat belt tension reducer. There should be battery current with the ignition switch
in the On or Accessory positions, and no battery current with the ignition switch in any other
position. If not OK, repair the shorted or open fused ignition switch output (run-accessory) circuit
between the tension reducer and the ignition switch as required.

Air Bag Deactivation Switch: Description and Operation
The passenger airbag on/off switch (1) is standard equipment on all standard cab versions of this
model when they are equipped with the dual front airbag system. This switch is a two-position,
resistor multiplexed switch with a single integral red Light-Emitting Diode (LED), and a non-coded
key cylinder-type actuator. The switch is located in the lower right corner of instrument panel center
bezel, near the center of instrument panel to make the Off indicator (3) visible to all front seat
occupants.
When the switch is in its installed position, the only components visible through the dedicated
opening of the cluster bezel are the switch face plate (2) and nomenclature, and the key cylinder
actuator (4). The "Off" position of the switch is illuminated when this switch position is selected,
while the "On" position of the switch is designated by text imprinted upon the face plate of the
switch, but is not illuminated. The remainder of the switch is concealed behind the switch face plate
and the instrument panel center bezel.
The passenger airbag on/off switch housing is constructed of molded plastic and has three integral
mounting tabs. These mounting tabs are used to secure the switch to the back of the molded
plastic switch face plate with three small screws. The molded plastic face plate also has three
integral mounting tabs that are used to secure the switch and face plate unit to the instrument
panel center bezel with three additional screws.
A molded plastic connector receptacle on the back of the switch housing connects the switch to the
vehicle electrical system through a dedicated take out and connector of the instrument panel wire
harness. The molded plastic harness connector insulator is keyed and latched to ensure proper
and secure switch electrical connections. The passenger airbag on/off switch cannot be adjusted or
repaired and, if faulty or damaged, the switch must be replaced.
The passenger airbag on/off switch allows the customer to turn the passenger airbag function On
or Off to accommodate certain uses of the right front seating position where airbag protection may
not be desired. See the vehicle glove box for specific recommendations on when to enable or
disable the passenger airbag. The Off indicator of the switch will be illuminated whenever the
switch is turned to the Off position and the ignition switch is in the On position.
The ignition key is the only key or object that should ever be inserted into the key cylinder actuator
of the switch. The on/off switch requires only a partial key insertion to fully depress a spring-loaded
locking plunger. The spring-loaded locking plunger prevents the user from leaving the key in the
switch. The key will be automatically ejected when force is not applied. To actuate the passenger
airbag on/off switch, insert the ignition key into the switch key actuator far enough to fully depress
the plunger, then rotate the actuator to the desired switch position.
When the switch key actuator is rotated to its clockwise stop (the key actuator slot will be aligned
with the Off indicator), the Off indicator is illuminated and the passenger airbag is disabled. When
the switch is rotated to its counterclockwise stop (the key actuator slot will be in a vertical position),
the Off indicator will be extinguished and the passenger airbag is enabled.
The passenger airbag on/off switch connects one of two internal resistors in series between the
passenger airbag mux switch sense and passenger airbag mux switch return circuits of the Airbag
Control Module (ACM). The ACM continually monitors the resistance in these circuits to determine
the switch position that has been selected.
When the switch is in the Off position, the ACM provides a ground input to the switch through the
passenger airbag indicator driver circuit, which energizes the Light-Emitting Diode (LED) that
illuminates the Off indicator of the switch. The ACM will also illuminate the Off indicator of the
switch for about seven seconds each time the ignition switch is turned to the On position as a bulb
test.
The ACM will store a Diagnostic Trouble Code (DTC) for any fault it detects in the passenger
airbag on/off switch or Off indicator circuits, and will illuminate the airbag indicator in the instrument
cluster if a fault is detected. For proper diagnosis of the passenger airbag on/off switch or the ACM,
a diagnostic scan tool is required.

Impact Sensor: Description and Operation
Two side impact sensors (1) are used on this model when it is equipped with the optional side
curtain air-bags, one each for the left and right sides of the vehicle. These sensors are mounted
remotely from the bi-directional safing sensor that is internal to the Air-bag Control Module (ACM).
Each side impact sensor is secured with a nut within the right or left B-pillar just above the front
seat belt retractors and behind the lower B-pillar trim within the passenger compartment. The
sensor housing has an integral connector receptacle (2), an integral mounting stud (3), and an
integral anti-rotation pin.
The right and left side impact sensors are identical in construction and calibration. A cavity in the
center of the molded black plastic impact sensor housing contains the electronic circuitry of the
sensor which includes an electronic communication chip and an electronic impact sensor. Potting
material fills the cavity to seal and protect the internal electronic circuitry and components. The side
impact sensors are each connected to the vehicle electrical system through a dedicated take out
and connector of the body wire harness.
The side impact sensors cannot be repaired or adjusted and, if damaged or faulty, they must be
replaced.
The side impact sensors are electronic accelerometers that sense the rate of vehicle deceleration,
which provides verification of the direction and severity of an impact. Each sensor also contains an
electronic communication chip that allows the unit to communicate the sensor status as well as
sensor fault information to the microprocessor in the Airbag Control Module (ACM).
The ACM microprocessor continuously monitors all of the side passive restraint system electrical
circuits to determine the system readiness. If the ACM detects a monitored system fault, it sets a
Diagnostic Trouble Code (DTC) and controls the airbag indicator operation accordingly. The impact
sensors each receive battery current and ground through dedicated left and right sensor plus and
minus circuits from the ACM. The impact sensors and the ACM communicate by modulating the
voltage in the sensor plus circuit.
The hard wired circuits between the side impact sensors and the ACM may be diagnosed and
tested using conventional diagnostic tools and procedures. However, conventional diagnostic
methods will not prove conclusive in the diagnosis of the ACM, the impact sensors, or the
electronic message inputs to or outputs from the impact sensors. The most reliable, efficient, and
accurate means to diagnose the impact sensors, the ACM, and the electronic message
communication between the sensors and the ACM requires the use of a diagnostic scan tool.

Seat Belt Buckle Switch: Description and Operation
The seat belt switch is a small, normally open, single pole, single throw, leaf contact, momentary
switch. Only one seat belt switch is installed in the vehicle, and it is integral to the buckle of the
driver side front seat belt buckle-half, located on the inboard side of the driver side front seat track
(4). The seat belt switch is connected to the vehicle electrical system through a two-wire pigtail wire
(3) and connector on the seat belt buckle-half (1), which is connected to a wire harness connector
and take out of the seat wire harness routed beneath the driver side front seat cushion (2) in the
passenger compartment.
The seat belt switch cannot be adjusted or repaired and, if faulty or damaged, the entire driver side
front seat belt buckle-half unit must be replaced.
The seat belt switch is designed to control a path to ground for the seat belt switch sense input of
the ElectroMechanical Instrument Cluster (EMIC). When the driver side front seat belt tip-half is
inserted into the seat belt buckle, the switch closes the path to ground; and, when the driver side
front seat belt tip-half is removed from the seat belt buckle, the switch opens the ground path. The
switch is actuated by the latch mechanism within the seat belt buckle.
The seat belt switch is connected in series between ground and the seat belt switch sense input of
the instrument cluster. The seat belt switch receives ground at all times through its pigtail wire
connection to the seat wire harness from a take out of the body wire harness. An eyelet terminal
connector on the body wire harness ground take out is secured beneath a ground screw on the left
cowl side inner panel, beneath the instrument panel. The seat belt switch may de diagnosed using
conventional diagnostic tools and methods.

Alarm Module: Description and Operation
The Sentry Key Immobilizer Module (SKIM) (1) is the primary component of the Sentry Key
Immobilizer System (SKIS). This module contains a Radio Frequency (RF) transceiver and a
central processing unit, which includes the Sentry Key Immobilizer System (SKIS) program logic.
The SKIM is located on the right side of the steering column, near the ignition lock cylinder housing
and is concealed beneath the steering column shrouds. The molded black plastic housing for the
SKIM has an integral molded plastic halo-like antenna ring (4) that extends from the bottom. When
the SKIM is properly installed on the steering column, the antenna ring is oriented around the
circumference of the ignition lock cylinder housing.
A single integral connector receptacle (3) is located just behind the antenna ring on the bottom of
the SKIM housing. An integral molded plastic mounting tab (2) on the rear corner of the SKIM
housing has a hole in the center through which a screw passes to secure the unit to the steering
column. The SKIM is connected to the vehicle electrical system through a single take out and
connector of the instrument panel wire harness.
The Sentry Key Immobilizer Module (SKIM) transmits Radio Frequency (RF) signals to, and
receives RF signals from the Sentry Key transponder through a tuned antenna enclosed within the
molded plastic antenna ring. If this antenna ring is not mounted properly around the ignition lock
cylinder housing, communication problems between the SKIM and the transponder may arise.
These communication problems will result in Sentry Key transponder-related faults. The SKIM also
communicates over the Programmable Communications Interface (PCI) data bus with the
Powertrain Control Module (PCM) for gasoline engines or the Engine Control Module (ECM) for
diesel engines, the ElectroMechanical Instrument Cluster (EMIC) and/or a diagnostic scan tool.
The SKIM and the PCM/ECM both use software that includes a rolling code algorithm strategy,
which helps to reduce the possibility of unauthorized Sentry Key Immobilizer System (SKIS)
disarming. The rolling code algorithm ensures security by preventing an override of the SKIS
through the unauthorized substitution of the SKIM or the PCM/ECM. However, the use of this
strategy also means that replacement of either the SKIM or the PCM/ECM units will require a
system initialization procedure to restore system operation.
The SKIM retains in memory the ID numbers of any Sentry Key transponder that is programmed
into it. A maximum of eight Sentry Key transponders can be programmed into the SKIM. For added
system security, each SKIM is programmed with a unique Secret Key code. This code is stored in
memory, sent over the PCI data bus to the PCM or ECM, and is encoded to the transponder of
every Sentry Key that is programmed into the SKIM. Therefore, the Secret Key code is a common
element that is found in every component of the SKIS.
Another security code called a PIN, is used to gain access to the SKIM Secured Access Mode. The
Secured Access Mode is required during service to perform the SKIS initialization and Sentry Key
transponder programming procedures. The SKIM also stores the Vehicle Identification Number
(VIN) in its memory, which it learns through a PCI data bus message from the PCM or ECM during
SKIS initialization.
In the event that a SKIM replacement is required, the Secret Key code can be transferred to the
new SKIM from the PCM using a diagnostic scan tool and the SKIS initialization procedure. Proper
completion of the SKIS initialization will allow the existing Sentry Keys to be programmed into the
new SKIM so that new keys will not be required. In the event that the original Secret Key code
cannot be recovered, SKIM replacement will also require new Sentry Keys. The diagnostic scan
tool will alert the technician during the SKIS initialization procedure if new Sentry Keys are
required.
When the ignition switch is turned to the On or Start positions, the SKIM transmits an RF signal to
excite the transponder in the ignition key. The SKIM then listens for a return RF signal from the
transponder. If the SKIM receives an RF signal with a valid "Secret Key" and transponder
identification codes, the SKIM sends a "valid key" message to the PCM/ECM over the PCI bus. If
the SKIM receives an invalid RF signal or no response, it sends "invalid key" messages to the
PCM/ECM. The PCM/ECM will enable or disable engine operation based upon the status of the
SKIM messages. It is important to note that the default condition in the PCM or ECM is an invalid
key. Therefore, if no message is received from the SKIM by the PCM or ECM, the engine will be
disabled and the vehicle immobilized after two seconds of running.

Antitheft) > Component Information > Description and Operation > Page 6452
The SKIM also sends electronic messages to the EMIC which control the VTSS indicator. The
SKIM sends messages to the EMIC to turn the indicator on for about three seconds when the
ignition switch is turned to the On position as a bulb test. After completion of the bulb test, the
SKIM sends bus messages to keep the indicator off for a duration of about one second. Then the
SKIM sends messages to turn the indicator on or off based upon the results of the SKIS self-tests.
If the VTSS indicator comes on and stays on after the bulb test, it indicates that the SKIM has
detected a system malfunction and/or that the SKIS has become inoperative.
If the SKIM detects an invalid key when the ignition switch is turned to the On position, it sends
messages to flash the VTSS indicator. The SKIM can also send messages to flash the indicator
and to generate a single audible chime whenever the Customer Learn programming mode is being
utilized.
The SKIS will store fault information in the form of Diagnostic Trouble Codes (DTC's) in SKIM
memory if a system malfunction is detected. For diagnosis or initialization of the SKIM and the
PCM/ECM, a diagnostic scan tool is required.

Alarm System Transponder: Description and Operation
Each ignition key (4) used in the Sentry Key Immobilizer System (SKIS) has an integral
transponder chip (2) concealed beneath the molded rubber cap (1), where it is secured within a
plastic mount in the head (3) of the metal key. In addition to having to be cut to match the
mechanical coding of the ignition lock cylinder, each new Sentry Key has a unique transponder
identification code that is permanently programmed into it by the manufacturer, and which must be
programmed into the Sentry Key Immobilizer Module (SKIM) to be recognized as a valid key. The
Sentry Key transponder cannot be adjusted or repaired. If faulty or damaged, the entire key and
transponder unit must be replaced.
When the ignition switch is turned to the On position, the Sentry Key Immobilizer Module (SKIM)
communicates through its antenna with the Sentry Key transponder using a Radio Frequency (RF)
signal. The SKIM then listens for a RF response from the transponder through the same antenna.
The Sentry Key transponder chip is within the range of the SKIM transceiver antenna ring when it is
inserted into the ignition lock cylinder. The SKIM determines whether a valid key is present in the
ignition lock cylinder based upon the response from the transponder. If a valid key is detected, that
fact is communicated by the SKIM to the Powertrain Control Module (PCM) over the Programmable
Communications Interface (PCI) data bus, and the PCM allows the engine to continue running. If
the PCM receives an invalid key message, or receives no message from the SKIM over the PCI
data bus, the engine will be disabled after about two seconds of operation. The ElectroMechanical
Instrument Cluster (EMIC) will also respond to the invalid key message on the PCI data bus by
flashing the security indicator on and off.
Each Sentry Key has a unique transponder identification code permanently programmed into it by
the manufacturer. Likewise, the SKIM has a unique Secret Key code programmed into it by the
manufacturer. When a Sentry Key is programmed into the memory of the SKIM, the SKIM stores
the transponder identification code from the Sentry Key, and the Sentry Key learns the Secret Key
code from the SKIM. Once the Sentry Key learns the Secret Key code of the SKIM, it is
permanently stored in the memory of the transponder. Therefore, once a Sentry Key has been
programmed to a particular vehicle, it cannot be used on any other vehicle.
The SKIS performs a self-test each time the ignition switch is turned to the On position, and will
store key-related fault information in the form of Diagnostic Trouble Code (DTC) in SKIM memory if
a Sentry Key transponder problem is detected. The Sentry Key transponder chip can be
diagnosed, and any stored DTC can be retrieved using a diagnostic scan tool.

Keyless Entry Module: Description and Operation
When an RKE lock message is sent to the instrument cluster, the instrument cluster actuates the
door locks, the interior lighting is turned off, the horn chirps (if this feature is enabled), the park
lamps flash (if this feature is enabled) and, if the vehicle is so equipped, the Vehicle Theft Security
System (VTSS) is armed. When an RKE unlock message is sent to the instrument cluster, the
instrument cluster actuates the driver side front door (or all doors if this feature is enabled) unlock,
the interior lighting is turned on and, if the vehicle is so equipped, the VTSS is disarmed.
When an RKE panic message is sent to the instrument cluster, the instrument cluster actuates the
driver side front door (or all doors if this feature is enabled) unlock, the interior lighting is turned on
and, if the vehicle is so equipped, the VTSS is disarmed. The panic message will also cause the
exterior lamps (including the headlights) to flash, and the horn to sound for about three minutes, or
until a second panic message is sent to the instrument cluster. A vehicle speed of about 25.7
kilometers-per-hour (15 miles-per-hour) will also cancel the panic event.
Whenever the vehicle battery power is interrupted, the Remote Keyless Module (RKE) Module will
retain all vehicle access codes in its memory. When replacing or adding a key fob transmitter
(maximum of 4) a scan tool is required to program the RKE Module to accept the new Vehicle
Access Code if a customer owned transmitter is not available.

Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Accessories and Optional Equipment > Antitheft and Alarm Systems > Security Lamp/Indicator
> Component Information > Description and Operation
Security Lamp/Indicator: Description and Operation
A security indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional Vehicle Theft Security System (VTSS), this indicator is electronically
disabled. This indicator is located in the lower right quadrant of the instrument cluster, between the
speedometer and the coolant temperature gauge.
The security indicator consists of a small round cutout in the opaque layer of the instrument cluster
overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it
is not illuminated. A red Light Emitting Diode (LED) behind the cutout in the opaque layer of the
overlay causes the indicator to appear in red through the translucent outer layer of the overlay
when it is illuminated from behind by the LED, which is soldered onto the instrument cluster
electronic circuit board. The security indicator is serviced as a unit with the instrument cluster.
The security indicator gives an indication to the vehicle operator when the Vehicle Theft Security
System (VTSS) is arming or is armed. On models equipped with the Sentry Key Immobilizer
System (SKIS), the security indicator also gives an indication to the vehicle operator of the status of
the SKIS. This indicator is controlled by a transistor on the instrument cluster circuit board based
upon cluster programming, hard wired inputs to the cluster from the various security system
components, electronic messages received by the cluster from the Remote Keyless Entry (RKE)
module over a dedicated serial bus, and electronic messages received by the cluster from the
Sentry Key Immobilizer Module (SKIM) over the Programmable Communications Interface (PCI)
data bus.
The security indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster
logic circuit, and that logic will allow this indicator to operate whenever the instrument cluster
receives a battery current input on the fused B(+) circuit. Therefore, the LED can be illuminated
regardless of the ignition switch position. The LED only illuminates when it is provided a path to
ground by the instrument cluster transistor. Depending upon the programmed condition he indicator
can be illuminated solid, flashed at a slow rate (0.5 Hertz, 12.5 percent duty cycle), or flashed at a
fast rate (1 Hertz, 50 percent duty cycle). The instrument cluster will turn on the security indicator
for the following reasons:
Bulb Test - On vehicles equipped with the optional SKIS, each time the ignition switch is turned to
the On position the SKIM tells the cluster to illuminate the security indicator for about two seconds
as a bulb test.
- VTSS Indication - During the sixteen second VTSS arming function, the cluster will flash the
security indicator on and off repeatedly at a steady, fast rate to indicate that the VTSS is in the
process of arming. Following successful VTSS arming, the cluster flashes the security indicator on
and off continuously at a slower rate to indicate that the VTSS is armed. The security indicator
continues flashing at the slower rate until the VTSS is disarmed or triggered. The security indicator
will also flash at the fast rate to indicate that the VTSS has been triggered and is currently
alarming. If the VTSS has alarmed until the alarm timed out and then rearmed itself, the cluster will
flash the security indicator at a steady, slow rate for about thirty seconds after the VTSS is
disarmed.
- SKIS Lamp-On Message - Each time the cluster receives a lamp-on message from the SKIM, the
security indicator will be illuminated. The indicator can be flashed on and off, or illuminated solid, as
dictated by the SKIM message. The indicator remains illuminated solid or continues to flash until
the cluster receives a SKIS lamp-off message from the SKIM, or until the ignition switch is turned to
the Off position, whichever occurs first.
- Communication Error - On vehicles equipped with the optional SKIS, if the cluster receives no
SKIS lamp-on or lamp-off messages from the SKIM for twenty consecutive seconds, the security
indicator is illuminated by the instrument cluster. The indicator remains controlled and illuminated
by the cluster until a valid SKIS lamp-on or lamp-off message is received from the SKIM.
- Actuator Test - Each time the instrument cluster is put through the actuator test, the security
indicator will be turned on, then off again during the bulb check portion of the test to confirm the
functionality of the LED and the cluster control circuitry.
The instrument cluster circuitry controls the security indicator whenever the ignition switch is in the
Off position and the VTSS is arming, armed, or alarming. Whenever the ignition switch is in the On
or Start positions, the SKIM performs a self-test to decide whether the SKIS is in good operating
condition and whether a valid key is present in the ignition lock cylinder. The SKIM then sends the
proper lamp-on or lamp-off messages to the instrument cluster. For further diagnosis of the security
indicator or the instrument cluster circuitry that controls the indicator, refer to testing. If the
instrument cluster flashes the security indicator upon ignition On, or turns on the security indicator
solid after the bulb test, it indicates that a SKIS malfunction has occurred or that the SKIS is
inoperative.
For proper diagnosis of the VTSS, the SKIS, the SKIM, the PCI data bus, or the electronic
message inputs to the instrument cluster that control the security indicator, a diagnostic scan tool is
required.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Accessories and Optional Equipment > Driver/Vehicle Information Display > Component
Information > Diagrams > Diagram Information and Instructions > Page 6489
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Driver/Vehicle Information Display: Description and Operation Overhead Console
An overhead console is available on this vehicle and includes the following components:
- Front map/reading lamps
- A blue-green vacuum-fluorescent display screen - if equipped with trip computer
- Universal transmitter - if equipped
- Electronic Overhead Module (EOM)
The overhead console assembly is mounted by two snap clips and screws securing it to a molded
plastic retainer bracket located above the headliner. The EOM is accessed by removing the
overhead console from the bracket and pulling it away from the headliner.
COMPASS DISPLAY
All the available overhead consoles on this model include Compass information. While in the
compass/temperature mode, the compass will display the direction in which the vehicle is pointed
using the eight major compass headings (Examples: north is N, northeast is NE). The
self-calibrating compass unit requires no adjusting in normal use. The only calibration that may
prove necessary is to drive the vehicle at 5 to 8 kilometers-per-hour (3 to 5 miles-per-hour), on
level ground in a square shaped pattern. This will reorient the compass unit to its vehicle.
The compass unit also will compensate for magnetism the body of the vehicle may acquire during
normal use. However, avoid placing anything magnetic directly on the roof of the vehicle. Magnetic
mounts for an antenna, a repair order hat, or a funeral procession flag can exceed the
compensating ability of the compass unit if placed on the roof panel. Magnetic bit drivers used on
the fasteners that hold the overhead console assembly to the roof header can also affect compass
operation. If the vehicle roof should become magnetized, the demagnetizing procedure may be
required to restore proper compass operation.
TEMPERATURE DISPLAY
All the available overhead consoles on this model include Temperature information. The
temperature displays the outside ambient temperature in whole degrees. The temperature display
can be toggled from Fahrenheit to Celsius by selecting the desired U.S./Metric option from the
customer programmable features. The displayed temperature is not an instant reading of
conditions, but an average temperature. It may take the temperature display several minutes to
respond to a major temperature change, such as driving out of a heated garage into winter
temperatures.
When the ignition switch is turned to the Off position, the last displayed temperature reading stays
in the electronic control modules, (CMTC, EVIC) memory. When the ignition switch is turned to the
On position again, the electronic module will display the memory temperature for one minute; then
update the display to the current average temperature reading within five minutes.
The temperature function is supported by an ambient temperature sensor. This sensor is mounted
outside the passenger compartment near the front and center of the vehicle, and is hard wired to
the Front Control Module (FCM). The FCM sends temperature status messages to the module over
the Programmable Communications Interface (PCI) data bus circuit. For more information on the
ambient temperature sensor.

Driver/Vehicle Information Display: Description and Operation Universal Transmitter
The universal transmitter transceiver is integral to the overhead console (7). The only visible
component of the universal transmitter are the three transmitter push buttons (3). The buttons are
marked with one, two or three dots, respectively, for identification of each channel.
Each of the three universal transmitter push buttons controls an independent radio transmitter
channel. Each of these three channels can be trained to transmit a different radio frequency signal
for the remote operation of garage door openers, motorized gate openers, home or office lighting,
security systems or just about any other device that can be equipped with a radio receiver in the
286 to 399 MegaHertz (MHz) frequency range for remote operation. The universal transmitter is
capable of operating systems using either rolling code or non-rolling code technology.
The universal transmitter cannot be repaired, and is available for service only as part of the
Electronic Overhead Module (EOM). This unit includes the push button switches for both the
transmitter and compass mini trip computer.
The universal transmitter operates on a non-switched source of battery current so the unit will
remain functional, regardless of the ignition switch position. It can learn and store three separate
transmitter radio frequency codes to operate garage door openers, security gates and security
lighting. The overhead console display provides visual feedback to the driver, showing which
transmitter button is pressed. The system will not send operating signals if the vehicle theft security
alarm is armed. This prevents a perpetrator from breaking into a vehicle parked outside a home
and using the transmitter system to enter the home.

Driver/Vehicle Information Display: Testing and Inspection Self-Diagnostic Test
A self-diagnostic test is used to determine that the EOM is operating properly electrically. Initiate
the self-diagnostic test as follows:
NOTE: The compass mini-trip computer self - test can also be performed using a scan tool. Refer
to Auto Self Test under the System Tests.
1. With the ignition switch in the Off position, simultaneously depress and hold the STEP and
RESET buttons while rotating the ignition switch to
the Run/On position.
2. Continue to hold both buttons depressed until the EOM enters the display segment test. In this
test, all of the Vacuum Fluorescent Display (VFD)
segments are lighted while the EOM performs the following checks: Non-Volatile Memory Status (NVM)
- RAM Status
- ROM Status
- ASIC Communication Test Status
- Compass Test Status
- DC Status
- PCI data bus Communications Test
NOTE: If module is equipped with the Universal Transmitter, the module also checks "Universal
Transmitter Communication Test Status"
3. Following completion of these tests, the compass mini-trip computer will display one of two
messages: "FAIL" or "PASS." Press RESET or STEP
to exit and enter normal mode. Respond to these test results as follows: If no test result message is displayed, but compass mini-trip computer operation is still improper,
the use of a scan tool and the proper Diagnostic Procedures Information are required for further
diagnosis.
- If the "FAIL" message is displayed, the EOM is inoperative and must be replaced.
- If the "PASS" message is displayed, the EOM is OK, no faults are present.
- If any VFD segment does not light during the display segment test, the EOM is inoperative and
must be replaced.
4. If the first seven tests pass, the compass mini-trip computer shall verify that all the required PCI
bus messages are present on the PCI bus. If all
required messages are present on the PCI bus, or if the ignition switch is turned to the Off position,
the EOM will automatically return to normal operation. The required PCI bus messages are: Dimming message
- Fuel Used message
- Distance Pulses message
- Percentage Fuel Tank Full message
- Fuel Type message
- VIN (Vehicle Identification Number)
- Vehicle Speed message
- Last Engine Off Duration message
- Ambient Air Temperature message
NOTE:
- The Fuel Used message shall be ignored if the engine type is Diesel or Compressed Natural Gas.
- Pressing the STEP or RESET switches during any portion of the testing procedure will cause the
compass mini-trip computer to exit diagnostics and return to compass/temperature mode.
- If the compass functions, but accuracy is suspect, it may be necessary to perform a variation
adjustment. This procedure allows the compass unit to accommodate variations in the earth's
magnetic field strength, based on geographic location.
- If the compass reading has blanked out, and only "CAL" appears in the display, demagnetizing
may be necessary to remove excessive residual magnetic fields from the vehicle.

Driver/Vehicle Information Display: Testing and Inspection Universal Transmitter
Radio Frequency Detector #9001
If both the Transmitter and the compass mini trip computer display are inoperative, refer to testing
for further diagnosis. If the Universal Transmitter is inoperative, but the compass mini trip computer
display is operating normally. Retrain the Transmitter with a known good transmitter as instructed
and test the Transmitter operation again. If the unit is still inoperative, test the universal transmitter
with the Radio Frequency Detector special tool as described below:
1. Turn the Radio Frequency (RF) Detector ON. A "chirp" will sound and the green power LED will
light. If the green LED does not light, replace
the battery.
2. Hold the RF detector within one inch of the TRAINED universal transmitter and press any of the
transmitters buttons. 3. The red signal detection LEDs will light and the tool will beep if a radio
signal is detected. Repeat this test for each button. If any button is
inoperative, replace the universal transmitter assembly.

Pedal Positioning Motor: Description and Operation
MOTOR - ADJUSTABLE PEDALS
DESCRIPTION
The Adjustable Pedals System (APS) is designed to enable the fore and aft repositioning of the
brake and accelerator pedals. This results in improved ergonomics in relation to the steering wheel
for taller and shorter drivers. Being able to adjust the pedal positions also allows the driver to set
steering wheel tilt and seat position to the most comfortable position. The position of the brake and
accelerator pedals can be adjusted without compromising safety or comfort in actuating the pedals.
Change of pedal position is accomplished by means of a motor driven screw. Operating the
adjustable pedal switch activates the pedal drive motor (1). The pedal drive motor turns a screw
that changes the position of the brake and accelerator pedals. The pedal can be moved rearward
(closer to the driver) or for ward (away from driver). The brake pedal is moved on its drive screw to
a position where the driver feels most comfortable.
The accelerator pedal is moved at the same time and the same distance as the brake pedal.
Neither the pedal drive motor (1) nor drive mechanism are subject to the mechanical stress of
brake or accelerator application.
^ SYSTEM FEATURES: Range of Adjustment: The pedals may be adjusted up to 3 inches (75 mm)
- Pedal Adjustment Speed: 0.5 inch/seconds (12.5 mm/seconds)
- Pedal Adjustment Inhibitors: Pedal adjustment is inhibited when the vehicle is in reverse or when
cruise control is activated.

Amplifier: Description and Operation
The optional Infinity premium speaker system includes a separate Infinity audio power amplifier.
The amplifier is an eight-channel unit rated at 368 total output watts. The amplifier is located behind
the glove box. If equipped, an additional amplifier rated at 140 watts is located under the center
passenger seat.
The power amplifier electronically increases the frequency response of the normal audio signal
output from the radio amplifier in order to improve the acoustic performance of the speakers. On
vehicles equipped with an amplifier, the amplifier section of the radio becomes a pre-amplifier.
The amplifier receives audio signal inputs for speaker channels from the radio, then sends
amplified audio outputs through six separate channels with dedicated feed and return circuits to the
individual speakers.

Radio/Stereo Noise Filter > Component Information > Description and Operation
Radio/Stereo Noise Filter: Description and Operation
Radio noise suppression devices are Installed on this vehicle. Radio Frequency Interference (RFI)
and ElectroMagnetic Interference (EMI) can be produced by any on-board or external source of
electromagnetic energy. These electromagnetic energy sources can radiate electromagnetic
signals through the air, or conduct them through the vehicle electrical system.
When the audio system converts RFI or EMI to an audible acoustic wave form, it is referred to as
radio noise. This undesirable radio noise is generally manifested in the form of "buzzing," "hissing,"
"popping," "clicking," "crackling," and/or "whirring" sounds. In most cases, RFI and EMI radio noise
can be suppressed using a combination of vehicle and component grounding, filtering and
shielding techniques. This vehicle is equipped with factory-installed radio noise suppression
devices that were designed to minimize exposure to typical sources of RFI and EMI; thereby,
minimizing radio noise complaints.
Factory-installed radio noise suppression is accomplished primarily through circuitry or devices that
are integral to the factory-installed radios, audio power amplifiers and other on-board electrical
components such as generators, wiper motors, blower motors, and fuel pumps that have been
found to be potential sources of RFI or EMI. External radio noise suppression devices that are used
on this vehicle to control RFI or EMI, and can be serviced, include the following:
- Engine-to-body ground strap - This length of braided ground strap has an eyelet terminal
connector crimped to each end. One end is secured to the engine cylinder head(s). The other is
secured to the plenum at the exhaust heat shield forward/outer attaching stud.
- Resistor-type spark plugs - This type of spark plug has an internal resistor connected in series
between the spark plug terminal and the center electrode to help reduce the production of
electromagnetic radiation that can result in radio noise.
There are two common strategies that can be used to suppress Radio Frequency Interference
(RFI) and Electro-Magnetic Interference (EMI) radio noise. The first suppression strategy involves
preventing the production of RFI and EMI electromagnetic signals at their sources. The second
suppression strategy involves preventing the reception of RFI and EMI electromagnetic signals by
the audio system components.
The use of braided ground straps in key locations is part of the RFI and EMI prevention strategy.
These ground straps ensure adequate ground paths, particularly for high current components such
as many of those found in the starting, charging, ignition, engine control and transmission control
systems. An insufficient ground path for any of these high current components may result in radio
noise caused by induced voltages created as the high current seeks alternative ground paths
through components or circuits intended for use by, or in close proximity to the audio system
components or circuits.
Preventing the reception of RFI and EMI is accomplished by ensuring that the audio system
components are correctly installed in the vehicle. Loose, corroded or improperly soldered wire
harness connections, improperly routed wiring and inadequate audio system component grounding
can all contribute to the reception of RFI and EMI. A properly grounded antenna body and radio
chassis, as well as a shielded antenna coaxial cable with clean and tight connections will each help
reduce the potential for reception of RFI and EMI.

Remote Switch: Description and Operation
Two rocker-type switches (if equipped) are mounted on the back (instrument panel side) of the
steering wheel spokes. The switch on the left spoke is the seek switch and has seek up, seek
down, and preset station advance functions. The switch on the right spoke is the volume control
switch and has volume up, and volume down functions. The switch on the right spoke also includes
a "mode" control that allows the driver to sequentially select AM radio, FM radio, cassette player,
CD player or CD changer (if equipped).
The six switches in the two remote radio switch units are normally open, resistor multiplexed
momentary switches that are hard wired to the Integrated Power Module (IPM) through the
clockspring. The IPM sends a five volt reference signal to both switch units on one circuit, and
senses the status of all of the switches by reading the voltage drop on a second circuit.
When the IPM senses an input (voltage drop) from any one of the remote radio switches, it sends
the proper switch status messages on the Programmable Communication Interface (PCI) data bus
network to the radio receiver. The electronic circuitry within the radio receiver is programmed to
respond to these remote radio switch status messages by adjusting the radio settings as
requested. For diagnosis of the IPM or the PCI data bus, the use of a scan tool and the proper
Diagnostic Procedures information is recommended.

Alarm Module: Description and Operation
The Sentry Key Immobilizer Module (SKIM) (1) is the primary component of the Sentry Key
Immobilizer System (SKIS). This module contains a Radio Frequency (RF) transceiver and a
central processing unit, which includes the Sentry Key Immobilizer System (SKIS) program logic.
The SKIM is located on the right side of the steering column, near the ignition lock cylinder housing
and is concealed beneath the steering column shrouds. The molded black plastic housing for the
SKIM has an integral molded plastic halo-like antenna ring (4) that extends from the bottom. When
the SKIM is properly installed on the steering column, the antenna ring is oriented around the
circumference of the ignition lock cylinder housing.
A single integral connector receptacle (3) is located just behind the antenna ring on the bottom of
the SKIM housing. An integral molded plastic mounting tab (2) on the rear corner of the SKIM
housing has a hole in the center through which a screw passes to secure the unit to the steering
column. The SKIM is connected to the vehicle electrical system through a single take out and
connector of the instrument panel wire harness.
The Sentry Key Immobilizer Module (SKIM) transmits Radio Frequency (RF) signals to, and
receives RF signals from the Sentry Key transponder through a tuned antenna enclosed within the
molded plastic antenna ring. If this antenna ring is not mounted properly around the ignition lock
cylinder housing, communication problems between the SKIM and the transponder may arise.
These communication problems will result in Sentry Key transponder-related faults. The SKIM also
communicates over the Programmable Communications Interface (PCI) data bus with the
Powertrain Control Module (PCM) for gasoline engines or the Engine Control Module (ECM) for
diesel engines, the ElectroMechanical Instrument Cluster (EMIC) and/or a diagnostic scan tool.
The SKIM and the PCM/ECM both use software that includes a rolling code algorithm strategy,
which helps to reduce the possibility of unauthorized Sentry Key Immobilizer System (SKIS)
disarming. The rolling code algorithm ensures security by preventing an override of the SKIS
through the unauthorized substitution of the SKIM or the PCM/ECM. However, the use of this
strategy also means that replacement of either the SKIM or the PCM/ECM units will require a
system initialization procedure to restore system operation.
The SKIM retains in memory the ID numbers of any Sentry Key transponder that is programmed
into it. A maximum of eight Sentry Key transponders can be programmed into the SKIM. For added
system security, each SKIM is programmed with a unique Secret Key code. This code is stored in
memory, sent over the PCI data bus to the PCM or ECM, and is encoded to the transponder of
every Sentry Key that is programmed into the SKIM. Therefore, the Secret Key code is a common
element that is found in every component of the SKIS.
Another security code called a PIN, is used to gain access to the SKIM Secured Access Mode. The
Secured Access Mode is required during service to perform the SKIS initialization and Sentry Key
transponder programming procedures. The SKIM also stores the Vehicle Identification Number
(VIN) in its memory, which it learns through a PCI data bus message from the PCM or ECM during
SKIS initialization.
In the event that a SKIM replacement is required, the Secret Key code can be transferred to the
new SKIM from the PCM using a diagnostic scan tool and the SKIS initialization procedure. Proper
completion of the SKIS initialization will allow the existing Sentry Keys to be programmed into the
new SKIM so that new keys will not be required. In the event that the original Secret Key code
cannot be recovered, SKIM replacement will also require new Sentry Keys. The diagnostic scan
tool will alert the technician during the SKIS initialization procedure if new Sentry Keys are
required.
When the ignition switch is turned to the On or Start positions, the SKIM transmits an RF signal to
excite the transponder in the ignition key. The SKIM then listens for a return RF signal from the
transponder. If the SKIM receives an RF signal with a valid "Secret Key" and transponder
identification codes, the SKIM sends a "valid key" message to the PCM/ECM over the PCI bus. If
the SKIM receives an invalid RF signal or no response, it sends "invalid key" messages to the
PCM/ECM. The PCM/ECM will enable or disable engine operation based upon the status of the
SKIM messages. It is important to note that the default condition in the PCM or ECM is an invalid
key. Therefore, if no message is received from the SKIM by the PCM or ECM, the engine will be
disabled and the vehicle immobilized after two seconds of running.

Equipment > Alarm Module, (Vehicle Antitheft) > Component Information > Description and Operation > Page 6610
The SKIM also sends electronic messages to the EMIC which control the VTSS indicator. The
SKIM sends messages to the EMIC to turn the indicator on for about three seconds when the
ignition switch is turned to the On position as a bulb test. After completion of the bulb test, the
SKIM sends bus messages to keep the indicator off for a duration of about one second. Then the
SKIM sends messages to turn the indicator on or off based upon the results of the SKIS self-tests.
If the VTSS indicator comes on and stays on after the bulb test, it indicates that the SKIM has
detected a system malfunction and/or that the SKIS has become inoperative.
If the SKIM detects an invalid key when the ignition switch is turned to the On position, it sends
messages to flash the VTSS indicator. The SKIM can also send messages to flash the indicator
and to generate a single audible chime whenever the Customer Learn programming mode is being
utilized.
The SKIS will store fault information in the form of Diagnostic Trouble Codes (DTC's) in SKIM
memory if a system malfunction is detected. For diagnosis or initialization of the SKIM and the
PCM/ECM, a diagnostic scan tool is required.

Keyless Entry Module: Description and Operation
When an RKE lock message is sent to the instrument cluster, the instrument cluster actuates the
door locks, the interior lighting is turned off, the horn chirps (if this feature is enabled), the park
lamps flash (if this feature is enabled) and, if the vehicle is so equipped, the Vehicle Theft Security
System (VTSS) is armed. When an RKE unlock message is sent to the instrument cluster, the
instrument cluster actuates the driver side front door (or all doors if this feature is enabled) unlock,
the interior lighting is turned on and, if the vehicle is so equipped, the VTSS is disarmed.
When an RKE panic message is sent to the instrument cluster, the instrument cluster actuates the
driver side front door (or all doors if this feature is enabled) unlock, the interior lighting is turned on
and, if the vehicle is so equipped, the VTSS is disarmed. The panic message will also cause the
exterior lamps (including the headlights) to flash, and the horn to sound for about three minutes, or
until a second panic message is sent to the instrument cluster. A vehicle speed of about 25.7
kilometers-per-hour (15 miles-per-hour) will also cancel the panic event.
Whenever the vehicle battery power is interrupted, the Remote Keyless Module (RKE) Module will
retain all vehicle access codes in its memory. When replacing or adding a key fob transmitter
(maximum of 4) a scan tool is required to program the RKE Module to accept the new Vehicle
Access Code if a customer owned transmitter is not available.

Winch Relay: Description and Operation
RELAY PACK
DESCRIPTION
Relay Pack
Electrical operation of the control assembly consists of four heavy duty relays, a thermal-switch
located on the motor armature brush holder and a Low Voltage Interrupt (LVI) located in the control
assembly. The thermal-switch interrupts the power-in function and the LVI affects both the power-in
and power-out functions and must be reset by allowing the charging circuit voltage to rise above 10
volts for more than 30 seconds. The thermal switch is reset only by allowing the winch motor to
cool adequately (about 30 minutes). Relay number 1 and 3 control current flow through the field
windings and relay number 2 and 4 supply current to the motor armature.
OPERATION
In the power-out mode, relay number 2 and 3 are energized by the remote control switch. Current
flows from the positive battery terminal through relay number 3 then through the black motor cable
to the number 2 and number 1 field windings. From the black motor cable current then flows
through solenoid number 2 to the motor armature to ground.
In power-in mode, relay number 1 and 4 are energized. Current again flows from the battery
positive cable, but this time current flows through solenoid number 1 then through field winding
number 1. Current flowing in the reverse direction through the field windings cause the motor to
turn in the opposite direction. From the red motor cable current then flows through relay number 4
to the black cable going to the motor armature to ground.

Remote Switch: Description and Operation
Two rocker-type switches (if equipped) are mounted on the back (instrument panel side) of the
steering wheel spokes. The switch on the left spoke is the seek switch and has seek up, seek
down, and preset station advance functions. The switch on the right spoke is the volume control
switch and has volume up, and volume down functions. The switch on the right spoke also includes
a "mode" control that allows the driver to sequentially select AM radio, FM radio, cassette player,
CD player or CD changer (if equipped).
The six switches in the two remote radio switch units are normally open, resistor multiplexed
momentary switches that are hard wired to the Integrated Power Module (IPM) through the
clockspring. The IPM sends a five volt reference signal to both switch units on one circuit, and
senses the status of all of the switches by reading the voltage drop on a second circuit.
When the IPM senses an input (voltage drop) from any one of the remote radio switches, it sends
the proper switch status messages on the Programmable Communication Interface (PCI) data bus
network to the radio receiver. The electronic circuitry within the radio receiver is programmed to
respond to these remote radio switch status messages by adjusting the radio settings as
requested. For diagnosis of the IPM or the PCI data bus, the use of a scan tool and the proper
Diagnostic Procedures information is recommended.

Dodge Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector >
Component Information > Diagrams > Diagram Information and Instructions > Page 6662
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Component Information > Diagrams > Diagram Information and Instructions > Page 6665
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Trailer Connector: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

STANDARD PROCEDURE - TESTING OF VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Dodge Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector >
Component Information > Diagrams > Diagram Information and Instructions > Page 6681
- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Trailer Lamps: Description and Operation Trailer Tow Wiring
In addition to the trailer tow wiring provisions, all vehicles include right and left trailer tow stop/turn
relays installed in the PDC. When the FCM receives the appropriate inputs for normal turn signal,
hazard warning or brake lamp operation, it responds by also energizing or de-energizing these
trailer tow relays. When a trailer tow relay is energized, it provides battery voltage from a fused
B(+) fuse to the trailer lamps through the trailer tow wiring to synchronize the illumination and flash
rate of the trailer brake and turn signal lamps with those of the tow vehicle.

Trailer Lamps: Description and Operation Wiring-Trailer Tow
The rear body wire harness on the rear frame (1) of all vehicles is equipped with a take out with a
standard, light-duty 4-pin trailer tow connector (2) that is secured to the top of the trailer hitch
platform (4) behind the rear bumper. Vehicles equipped with an optional factory-installed trailer
towing package have a second take out with a connector (3) that plugs into a receptacle in the
back of a heavy duty, sealed, 7-pin trailer tow connector that is located near the center of the rear
bumper.
Vehicles equipped with the trailer tow package also include an electric trailer brake wiring provision
that terminates at a connector located on top of the large body harness connection under the
instrument panel to the left of the brake pedal, as well as an electric trailer brake pigtail harness
and an instruction card (1) that are stored in the glove box (2) when the vehicle is shipped from the
factory.
The wiring information includes wiring diagrams, proper wire and connector repair procedures,
further details on wire harness routing and retention, as well as pin-out and location views for the
various wire harness connectors, splices and grounds.
The standard 4-pin trailer tow connector contains the following vehicle circuits: park/tail lamps, left
stop/turn lamp, right stop/turn lamp, and ground. The optional trailer towing package 7-way
connector contains the same circuits as the 4-pin connector plus the following additional circuits:
backup lamp, trailer battery and electric brake.
If an aftermarket electric brake controller is used, the electric brake pigtail harness supplied will
make installation easier. The connection (blue 4-way connector) for the harness is located under
the instrument panel to the left of the brake pedal on top of the large body harness connection.
The battery line of this harness may be used to charge the trailer battery. However, a battery
isolation unit is not supplied and the trailer battery may discharge the truck battery while the engine
is not running. The battery line is protected by a fuse or a circuit breaker. Refer to the vehicle glove

These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information >
Diagrams > Diagram Information and Instructions > Page 6712
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information >
Diagrams > Diagram Information and Instructions > Page 6728
- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Winch Motor: Description and Operation
MOTOR
DESCRIPTION
Motor
The winch is driven on one end by a two direction electric motor powered by the vehicle electrical
system. The motor is internally protected by a thermal switch that is activated when the motor gets
too hot to operate efficiently.
Winch motor controls consist of a relay pack mounted to the motor, and a remote control
connected to the relay pack with a cord. The winch power source cables are connected to the relay
pack which in turn feeds power to the winch motor through electrical cable connections. The main
function of the relay pack is to allow the operator to switch the winch on and off in both directions.
The winch relay pack also includes a Low Voltage Interrupt (LVI) used to prevent winch operation
in the event of battery power dropping below 10 volts.

Winch Relay: Description and Operation
RELAY PACK
DESCRIPTION
Relay Pack
Electrical operation of the control assembly consists of four heavy duty relays, a thermal-switch
located on the motor armature brush holder and a Low Voltage Interrupt (LVI) located in the control
assembly. The thermal-switch interrupts the power-in function and the LVI affects both the power-in
and power-out functions and must be reset by allowing the charging circuit voltage to rise above 10
volts for more than 30 seconds. The thermal switch is reset only by allowing the winch motor to
cool adequately (about 30 minutes). Relay number 1 and 3 control current flow through the field
windings and relay number 2 and 4 supply current to the motor armature.
OPERATION
In the power-out mode, relay number 2 and 3 are energized by the remote control switch. Current
flows from the positive battery terminal through relay number 3 then through the black motor cable
to the number 2 and number 1 field windings. From the black motor cable current then flows
through solenoid number 2 to the motor armature to ground.
In power-in mode, relay number 1 and 4 are energized. Current again flows from the battery
positive cable, but this time current flows through solenoid number 1 then through field winding
number 1. Current flowing in the reverse direction through the field windings cause the motor to
turn in the opposite direction. From the red motor cable current then flows through relay number 4
to the black cable going to the motor armature to ground.

A/C Status Indicator Flashing
A/C STATUS INDICATOR FLASHING
Theory of Operation
Running the AC Cooldown test will cause the A/C status indicator to flash. If the test fails, the
status indicator will continue to flash until either the test returns passed or the ignition key is cycled.
When the A/C status indicator is flashing, it will not indicate A/C operating status. However, the A/C
mode switch will continue to function normally. For vehicles equipped with EBL, when the A/C
status indicator is flashing, the EBL status indicator will not function. However, the EBL mode
switch will continue to function normally.
POSSIBLE CAUSES
- A/C Cooldown test failed
1. PERFORM THE A/C COOLDOWN TEST
NOTE: The following are prerequisites of the Cooldown Test. Verify each of the following before
running the test:
- Verify that no Evaporator Temperature Sensor related DTCs are not active. If active, diagnose
and repair the DTC before proceeding.
- Verify that the refrigerant system has an adequate charge. Check and repair as necessary before
proceeding.
- Verify that the blower motor operates correctly in all speeds. Diagnose and repair all blower
related faults before proceeding.
- Verify that the work area ambient temperature is above 21.1° C (70° F) before proceeding. Move
the vehicle to a warmer work area if necessary.
- Verify that the evaporator temperature is above 12.7° C (55° F) before proceeding.
- Verify that the Mode Select control is set to the panel position.
- Verify that the A/C compressor is not running. If the compressor is running, turn the A/C off and
allow the evaporator to warm up before proceeding.
Start the engine. Turn the Blower control to the high speed position.

NUMBER: 23-027-05
GROUP: Body
DATE: May 03, 2005
SUBJECT: Tonneau Cover Installation
MODELS:
2005 (DR) Ram Truck
DISCUSSION:
The MOPAR Snapless Tonneau Cover, p/n 82208129AB or 82208130AB may become damaged if
the installation instructions are not carefully followed. Damage can lead to poor fit and customer
dissatisfaction. The instructions included in the kit have been revised to include additional
warnings. The information included in the new instructions is highlighted below:
Use care when assembling the tonneau cover frame. The frame must be assembled in place, on
the pick up box. Do not assemble the frame on the floor and attempt to lift the assembly on to the
pick up box.
The rear loops sewn on to the corners of the tonneau cover are intended to aid in the removal of
the cover. Do not use the tabs as an installation aid to stretch the cover.
When installing the fabric on to the frame, the installation sequence is important for ease of
installation. Always start at the rear. Unroll the fabric and pull it rearward, gently stretching the
fabric. Start at the center of the tailgate so that the MOPAR logo is directly above the center of the
tailgate handle. Insert the plastic retainer in to the slot on the frame and work the plastic retainer
into the slot from the center outward to the corner. Do the same for the other side. After the entire
length of the rear retainer is secure, move to one of the front corners and start the plastic retainer
into the frame slot. Work rearward until the entire side is secure, then repeat this for the other side.
It is not necessary to use the removal loops if this procedure is followed.
To remove the cover, start at the corner with the removal loop. Pull the loop downward at a 45
degree angle until the plastic retainer disengages from the frame slot. Do not pull up on the loop.
Slowly disengage the ENTIRE rear of the Tonneau Cover from the Frame. You now have removed
the tension in the tonneau fabric, proceed to disengage both sides of the tonneau from the frame.
The tonneau then can be rolled up and secured with two (2) straps with buckles attached to the
tonneau.
All components contained in the kit are available through MOPAR. Replacement parts are listed in
STAR PARTS. It is not necessary to replace the entire kit if individual parts are damaged or lost.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams >
Diagram Information and Instructions > Page 7212
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Diagram Information and Instructions > Page 7215
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Fig.7 Testing For Voltage Potential
STANDARD PROCEDURE - TESTING OF VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

Fig.9 Testing For Voltage Drop
STANDARD PROCEDURE - TESTING FOR A VOLTAGE DROP
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery (Fig. 9).
2. Connect the other lead of the voltmeter to the other side of the switch, component or circuit. 3.
Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

1. Using a trim stick C-4755 or equivalent, gently pry on each side of the Airbag Control Module
(ACM) cover located under the cup holder and
remove the ACM cover.
2. Operated the cup holder with the ACM cover removed. If the cup holder now operates freely,
there is an interference between the ACM cover and
bottom of the cup holder. If the cup holder binds with the ACM cover removed, proceed to Step 6.
3. Install the ACM cover and inspect the area where the cup holder and the ACM cover come
together (3). There must be a gap between the ACM
cover and the bottom of the cup holder. If the ACM cover is in contact with cup holder, try
realigning the cover by pushing the bottom of the cover towards the front, if this provides a gap and
the cup holder now operates freely, the repair is complete. If the gap cannot be achieved by
adjusting the ACM cover proceed to the next step.
4. The ACM wire harness (1) runs rearward along the left side of the tunnel under the carpet. Rub
your hand along the carpet in the area of the
bottom of the ACM cover and feel for the harness. If the harness can be felt, it may be pushing the
ACM cover upward and into the cup holder. If this is happening it may be necessary to reroute the
harness or remove carpet padding from the area.
5. Roll the carpet back and make sure that there are no plastic retainers in the area that could
cause the interference. If a retainer is present remove it.
Make sure that the harness is not sitting on a raised portion of the floor. If it is, reroute the harness
to a lower area on the floor. Remove the any carpet padding from the area where the harness
contacts the carpet to gain additional clearance. This should provide the clearance needed, and
complete the repair.

Keyless Entry Module: Description and Operation
When an RKE lock message is sent to the instrument cluster, the instrument cluster actuates the
door locks, the interior lighting is turned off, the horn chirps (if this feature is enabled), the park
lamps flash (if this feature is enabled) and, if the vehicle is so equipped, the Vehicle Theft Security
System (VTSS) is armed. When an RKE unlock message is sent to the instrument cluster, the
instrument cluster actuates the driver side front door (or all doors if this feature is enabled) unlock,
the interior lighting is turned on and, if the vehicle is so equipped, the VTSS is disarmed.
When an RKE panic message is sent to the instrument cluster, the instrument cluster actuates the
driver side front door (or all doors if this feature is enabled) unlock, the interior lighting is turned on
and, if the vehicle is so equipped, the VTSS is disarmed. The panic message will also cause the
exterior lamps (including the headlights) to flash, and the horn to sound for about three minutes, or
until a second panic message is sent to the instrument cluster. A vehicle speed of about 25.7
kilometers-per-hour (15 miles-per-hour) will also cancel the panic event.
Whenever the vehicle battery power is interrupted, the Remote Keyless Module (RKE) Module will
retain all vehicle access codes in its memory. When replacing or adding a key fob transmitter
(maximum of 4) a scan tool is required to program the RKE Module to accept the new Vehicle
Access Code if a customer owned transmitter is not available.

Power Door Lock Switch: Description and Operation
A window/lock switch is used on all models equipped with power locks, power windows, and power
mirrors. The window/lock switch houses the following switches:
- Power Lock Switch - A two-way, momentary, resistor multiplexed switch to control the power lock
system.
- Power Mirror Selector Switch - A three-position rocker switch selects the right or left power mirror
for adjustment, or turns the power mirror system Off.
Power Mirror Adjustment Switches - Four momentary, arrowhead shaped, directional switches
allow the driver to adjust the selected power mirror in the Up, Down, Right, or Left directions.
- Power Window Lockout Switch - A two-way, latching, push-button switch allows the vehicle
operator to lock out the power window switches on each passenger door so that the passenger
door power windows may be operated only from the master switches.
- Power Window Switches - A two-way, momentary power window switch for the driver side front
door. This switch also has a second detent in the Down direction and internal circuitry to provide an
Auto-Down feature for the driver side front door power window. In addition to the power window
switch for its own door, there are individual master switches for each passenger door power
window.
The window/lock switch also incorporates several green Light-Emitting Diodes (LEDs) that
illuminate the power lock and power window switch paddles, and the power mirror switch
directional buttons to improve switch visibility.
The window/lock switch combines a power lock switch, a driver power window switch with an
Auto-down feature, master switches for each passenger door power window, a power window
lockout switch, a power mirror selector switch, and four power mirror adjustment switches in a
single unit.
Power Lock Switch
The power lock switch circuitry is connected in series between ground and the driver door switch
mux input of the instrument cluster. Each power lock switch position (Lock, Unlock, and Neutral)
provides a different resistance value to the instrument cluster input, which allows the instrument
cluster to sense the switch position. Based upon the power lock switch input, the instrument cluster
controls the battery and ground feed outputs to the individual power lock motors to lock or unlock
the door latches. The Light-Emitting Diode (LED) in the power lock switch is connected to battery
current through the power window circuit breaker in the Integrated Power Module (IPM) on a fused
ignition switch output (run-acc) circuit. The switch will be illuminated whenever the ignition switch is
in the On or Accessory positions.
Power Window Switches
The power window switch circuitry is connected to battery current through a circuit breaker in the
Integrated Power Module (IPM) on a fused ignition switch output (run-acc) circuit so that the power
windows will operate whenever the ignition switch is in the On or Accessory positions. Each
two-way, momentary master passenger power window switch provides battery current and ground
to the individual power window switches on each passenger door so that the power window switch
controls the battery current and ground feeds to its respective power window motor. The switch for
the driver side front door power window is labeled "Auto" and includes an auto-down feature. When
this switch is depressed to a second momentary detent position and released, the driver door
power window is automatically operated through an internal circuit and relay to its fully lowered
position. The Auto-down event is cancelled if the switch paddle is depressed a second time in
either the Up or Down direction. When the two position window lockout switch is depressed and
latched in the lockout position, the battery current feed to each of the individual passenger power
window switches is interrupted so that the passenger door power windows can only be operated
from the master switches. The window lockout switch also controls the battery current feed for the
LED in each passenger power window switch so that the switch will not be illuminated when it is
locked out.
Power Mirror Switches
The power mirror switch circuitry is connected to battery current through a fuse in the IPM on a
fused B(+) circuit so that the power mirrors remain operational regardless of the ignition switch
position. A rocker type selector switch has three positions, one to select the right mirror, one to
select the left mirror, and a neutral Off position. After the right or left mirror is selected, one of four
directional buttons is depressed to move the selected mirror Up, Down, Right or Left. The power
mirror switch circuitry controls the battery current and ground feeds to each of the four (two in each
mirror head) power mirror motors. The Light-Emitting Diode (LED) in the power mirror switch is
connected to battery current through the power window circuit breaker in the IPM on a fused
ignition switch output (run-acc) circuit so that the switch directional buttons will be illuminated
whenever the ignition switch is in the On or Accessory positions.

Heated Mirror Relay: Description and Operation
The heated mirror relay (1) is a International Standards Organization (ISO)-type relay. Relays
conforming to the ISO specifications have common physical dimensions, current capacities,
terminal functions and patterns (2). The heated mirror relay is a electromechanical device that
switches battery current through a fuse in the integrated power module (IPM) to the outside rear
view mirror heating grids. The heated mirror relay is energized when the relay coil is provided a
ground path by the control circuitry within the A/C-heater control.
The heated mirror relay is located in the IPM in the engine compartment.
The ISO-standard heated mirror relay is an electromechanical switch that uses a low current input
controlled by the A/C-heater control to control the high current output to the outside rear view mirror
heating grids. The movable, common feed relay contact is held against the fixed, normally closed
relay contact by spring pressure. When the electromagnetic relay coil is energized, it draws the
movable common feed relay contact away from the fixed, normally closed relay contact and, holds
it against the fixed, normally open relay contact. This action allows high current to flow to the
outside rear view mirror heating grids.
When the relay coil is de-energized, spring pressure returns the movable relay contact back
against the fixed, normally closed contact point. The resistor or diode is connected in parallel with
the relay coil, and helps to dissipate voltage spikes and electromagnetic interference that can be
generated as the electromagnetic field of the relay coil collapses.
The heated mirror relay terminals are connected to the vehicle electrical system through a
receptacle in the integrated power module (IPM). The inputs and outputs of the heated mirror relay
include:
- Terminal (30) receives fused battery current at all times.
- Terminal (86) receives a ground through the defogger relay control circuit only when the
A/C-heater control electronically pulls the circuit to ground.
- Terminal (85) receives fused battery current through an ignition switch output circuit only when
the ignition switch is in the Run position.
- Terminal (87) provides battery current to the heated outside rear view mirror grids through the
heated mirror relay output circuit only when the heated mirror relay coil is energized.
- Terminal (87A) is not connected to any circuit in this application, but provides a battery current
output only when the heated mirror relay coil is de-energized.
The heated mirror relay cannot be repaired and, if faulty or damaged, it must be replaced. Refer to
the appropriate wiring information for diagnosis and testing of the ISO-standard relay and for
complete heated mirror system wiring diagrams.

BASECOAT/CLEARCOAT FINISH
DESCRIPTION
The original equipment paint finish is a multi step process that involves cleaning, applying electro
de-position (E-coat), anti-chip primer, basecoat, and clearcoat steps.
CAUTION: Do not use abrasive chemicals, abrasive compounds or harsh alkaline based cleaning
solvents on the painted surfaces of a vehicle. Failure to follow this caution can result in damage to
vehicle finish.
On most vehicles a two-part paint application (basecoat/clearcoat) is used. Color paint that is
applied to primer is called basecoat. A clear coat paint is then applied to protect the basecoat from
ultraviolet light and to provide a durable high-gloss finish.

soon as possible to avoid corrosion.
WARNING: Use an OSHA approved respirator and safety glasses when spraying paint or solvents
in a confined area. Failure to follow this warning may result in possible personal injury or death.
When repairing painted metal surfaces, for best results, use MOPAR(R) Scratch Filler/Primer,
Touch-Up Paints and Clear Top Coat.
STANDARD PROCEDURE
PAINT TOUCH-UP
1. Scrape any loose paint and corrosion from inside the scratch or chip.
WARNING: Avoid prolonged skin contact with petroleum or alcohol-based cleaning solvents.
Failure to follow this warning can result in possible personal injury or death.
2. Clean affected area with MOPAR(R) Tar/Road Oil Remover or equivalent, and allow to dry. 3.
Fill the inside of the scratch or chip with a coat of filler/primer. Do not overlap primer onto good
surface finish. The applicator brush should be
wet enough to puddle-fill the scratch or chip without running. Do not stroke brush applicator on
body surface. Allow the filler/primer to dry hard.
4. Cover the filler/primer with color touch-up paint. Do not overlap touch-up color onto the original
color coat around the scratch or chip. Butt the
new color to the original color, if possible. Do not stroke applicator brush on body surface. Allow
touch-up paint to dry hard.
5. On vehicles without clearcoat, the touch-up color can be lightly finesse sanded (1500 grit) and
polished with rubbing compound. 6. On vehicles with clearcoat, apply clear top coat to touch-up
paint with the same technique as described in Step 4. Allow clear top coat to dry hard.
If desired, the clearcoat can be lightly finesse sanded (1500 grit) and polished with rubbing
compound.

Heated Mirror Relay: Description and Operation
The heated mirror relay (1) is a International Standards Organization (ISO)-type relay. Relays
conforming to the ISO specifications have common physical dimensions, current capacities,
terminal functions and patterns (2). The heated mirror relay is a electromechanical device that
switches battery current through a fuse in the integrated power module (IPM) to the outside rear
view mirror heating grids. The heated mirror relay is energized when the relay coil is provided a
ground path by the control circuitry within the A/C-heater control.
The heated mirror relay is located in the IPM in the engine compartment.
The ISO-standard heated mirror relay is an electromechanical switch that uses a low current input
controlled by the A/C-heater control to control the high current output to the outside rear view mirror
heating grids. The movable, common feed relay contact is held against the fixed, normally closed
relay contact by spring pressure. When the electromagnetic relay coil is energized, it draws the
movable common feed relay contact away from the fixed, normally closed relay contact and, holds
it against the fixed, normally open relay contact. This action allows high current to flow to the
outside rear view mirror heating grids.
When the relay coil is de-energized, spring pressure returns the movable relay contact back
against the fixed, normally closed contact point. The resistor or diode is connected in parallel with
the relay coil, and helps to dissipate voltage spikes and electromagnetic interference that can be
generated as the electromagnetic field of the relay coil collapses.
The heated mirror relay terminals are connected to the vehicle electrical system through a
receptacle in the integrated power module (IPM). The inputs and outputs of the heated mirror relay
include:
- Terminal (30) receives fused battery current at all times.
- Terminal (86) receives a ground through the defogger relay control circuit only when the
A/C-heater control electronically pulls the circuit to ground.
- Terminal (85) receives fused battery current through an ignition switch output circuit only when
the ignition switch is in the Run position.
- Terminal (87) provides battery current to the heated outside rear view mirror grids through the
heated mirror relay output circuit only when the heated mirror relay coil is energized.
- Terminal (87A) is not connected to any circuit in this application, but provides a battery current
output only when the heated mirror relay coil is de-energized.
The heated mirror relay cannot be repaired and, if faulty or damaged, it must be replaced. Refer to
the appropriate wiring information for diagnosis and testing of the ISO-standard relay and for
complete heated mirror system wiring diagrams.

Keyless Entry Module: Description and Operation
When an RKE lock message is sent to the instrument cluster, the instrument cluster actuates the
door locks, the interior lighting is turned off, the horn chirps (if this feature is enabled), the park
lamps flash (if this feature is enabled) and, if the vehicle is so equipped, the Vehicle Theft Security
System (VTSS) is armed. When an RKE unlock message is sent to the instrument cluster, the
instrument cluster actuates the driver side front door (or all doors if this feature is enabled) unlock,
the interior lighting is turned on and, if the vehicle is so equipped, the VTSS is disarmed.
When an RKE panic message is sent to the instrument cluster, the instrument cluster actuates the
driver side front door (or all doors if this feature is enabled) unlock, the interior lighting is turned on
and, if the vehicle is so equipped, the VTSS is disarmed. The panic message will also cause the
exterior lamps (including the headlights) to flash, and the horn to sound for about three minutes, or
until a second panic message is sent to the instrument cluster. A vehicle speed of about 25.7
kilometers-per-hour (15 miles-per-hour) will also cancel the panic event.
Whenever the vehicle battery power is interrupted, the Remote Keyless Module (RKE) Module will
retain all vehicle access codes in its memory. When replacing or adding a key fob transmitter
(maximum of 4) a scan tool is required to program the RKE Module to accept the new Vehicle
Access Code if a customer owned transmitter is not available.

Power Seat Control Module: Description and Operation
The heated seat module (2) is also known as the Seat Heat Interface Module. The heated seat
module is located under the drivers front seat cushion, where it is secured to a mounting bracket.
The heated seat module has a single connector receptacle (3) that allows the module to be
connected to all of the required inputs and outputs through the seat wire harness.
The heated seat module is an electronic microprocessor controlled device designed and
programmed to use inputs from the battery, the two heated seat switches and the two heated seat
sensors to operate and control the heated seat elements in both front seats and the two heated
seat indicator lamp Light-Emitting Diodes (LEDs) in each heated seat switch. The heated seat
module is also programmed to perform self-diagnosis of certain heated seat system functions and
provide feedback of that diagnosis through the heated seat switch indicator lamps.
The heated seat module cannot be repaired. If the heated seat module is damaged or faulty, the
entire module must be replaced.
The heated seat module operates on fused battery current received from the integrated power
module. Inputs to the module include a resistor multiplexed heated seat switch request circuit for
each of the two heated seat switches and the heated seat sensor inputs from the seat cushions of
each front seat. In response to those inputs the heated seat module controls battery current feeds
to the heated seat elements and sensors, and controls the ground for the heated seat switch
indicator lamps.
When a heated seat switch (Driver or Passenger) is depressed a signal is received by the heated
seat module, the module energizes the proper indicator LED (Low or High) in the switch by
grounding the indicator lamp circuit to indicate that the heated seat system is operating. At the
same time, the heated seat module energizes the selected heated seat sensor circuit and the
sensor provides the module with an input indicating the surface temperature of the selected seat
cushion.
The Low heat set point is about 36° C (96.8° F), and the High heat set point is about 42°C (107.6°
F). If the seat cushion surface temperature input is below the temperature set point for the selected
temperature setting, the heated seat module energizes an N-channel Field Effect Transistor
(N-FET) within the module which energizes the heated seat elements in the selected seat cushion
and back. When the sensor input to the module indicates the correct temperature set point has
been achieved, the module de-energizes the N-FET which de-energizes the heated seat elements.
The heated seat module will continue to cycle the N-FET as needed to maintain the selected
temperature set point.
If the heated seat module detects a heated seat sensor value input that is out of range or a shorted
or open heated seat element circuit, it will notify the vehicle operator or the repair technician of this
condition by flashing the High and/or Low indicator lamps in the affected heated seat switch.

Sunroof / Moonroof Switch: Description and Operation
The power sunroof switch (3) is a combination push button and rocker switch module mounted in
the overhead console. The sunroof switch is a direct contact unit that is directly wired to the sunroof
motor/module assembly. The sunroof switch performs the following functions:
- Power sunroof open (back of switch pushed)
- Power sunroof closed (front of switch pushed)
- Power sunroof vent (switch center button pushed)
The power sunroof switch is part of the overhead console assembly and cannot be replaced
separately. If the switch is damaged or inoperative the overhead console must be replaced.
The power sunroof switch is hard wired to the sunroof motor/module assembly. The switch
receives battery current from the motor/module when the ignition switch is in the RUN and

Description and Operation
Power Seat Control Module: Description and Operation
The heated seat module (2) is also known as the Seat Heat Interface Module. The heated seat
module is located under the drivers front seat cushion, where it is secured to a mounting bracket.
The heated seat module has a single connector receptacle (3) that allows the module to be
connected to all of the required inputs and outputs through the seat wire harness.
The heated seat module is an electronic microprocessor controlled device designed and
programmed to use inputs from the battery, the two heated seat switches and the two heated seat
sensors to operate and control the heated seat elements in both front seats and the two heated
seat indicator lamp Light-Emitting Diodes (LEDs) in each heated seat switch. The heated seat
module is also programmed to perform self-diagnosis of certain heated seat system functions and
provide feedback of that diagnosis through the heated seat switch indicator lamps.
The heated seat module cannot be repaired. If the heated seat module is damaged or faulty, the
entire module must be replaced.
The heated seat module operates on fused battery current received from the integrated power
module. Inputs to the module include a resistor multiplexed heated seat switch request circuit for
each of the two heated seat switches and the heated seat sensor inputs from the seat cushions of
each front seat. In response to those inputs the heated seat module controls battery current feeds
to the heated seat elements and sensors, and controls the ground for the heated seat switch
indicator lamps.
When a heated seat switch (Driver or Passenger) is depressed a signal is received by the heated
seat module, the module energizes the proper indicator LED (Low or High) in the switch by
grounding the indicator lamp circuit to indicate that the heated seat system is operating. At the
same time, the heated seat module energizes the selected heated seat sensor circuit and the
sensor provides the module with an input indicating the surface temperature of the selected seat
cushion.
The Low heat set point is about 36° C (96.8° F), and the High heat set point is about 42°C (107.6°
F). If the seat cushion surface temperature input is below the temperature set point for the selected
temperature setting, the heated seat module energizes an N-channel Field Effect Transistor
(N-FET) within the module which energizes the heated seat elements in the selected seat cushion
and back. When the sensor input to the module indicates the correct temperature set point has
been achieved, the module de-energizes the N-FET which de-energizes the heated seat elements.
The heated seat module will continue to cycle the N-FET as needed to maintain the selected
temperature set point.
If the heated seat module detects a heated seat sensor value input that is out of range or a shorted
or open heated seat element circuit, it will notify the vehicle operator or the repair technician of this
condition by flashing the High and/or Low indicator lamps in the affected heated seat switch.

Power Seat Switch: Description and Operation
The power seats on this vehicle can be adjusted in eight different directions, up, down, front up,
front down, rear up, rear down, rearward and forward. The power seat switch is located on the
outboard side of the seat cushion on the seat cushion side shield.
The individual switches in the power seat switch assembly cannot be repaired. If one switch is
damaged or inoperative, the entire power seat switch assembly must be replaced.
When a power switch control knob or knobs are actuated, a battery feed and a ground path are
applied through the switch contacts to the power seat track adjuster motor. The selected adjuster
motor operates to move the seat track or recliner through its drive unit in the selected direction until
the switch is released, or until the travel limit of the adjuster is reached. When the switch is moved
in the opposite direction, the battery feed and ground path to the motor are reversed through the
switch contacts. This causes the adjuster motor to run in the opposite direction.
No power seat switch should be held applied in any direction after the adjuster has reached its
travel limit. The power seat adjuster motors each contain a self-resetting circuit breaker to protect
them from overload. However, consecutive or frequent resetting of the circuit breaker must not be
allowed to continue, or the motor may be damaged.

WARNING: THE FRONT PASSENGER SEAT ASSEMBLY CONTAINS CRITICAL COMPONENTS
THAT AFFECT THE FRONT PASSENGER AIRBAG DEPLOYMENT. CORRECTLY
FUNCTIONING FRONT PASSENGER SEAT COMPONENTS ARE CRITICAL FOR THE
OCCUPANT CLASSIFICATION SYSTEM (OCS) TO PROPERLY CLASSIFY THE FRONT
PASSENGER AND CALCULATE THE PROPER AIRBAG DEPLOYMENT. UNAPPROVED
MODIFICATIONS OR SERVICE PROCEDURES TO THE FRONT PASSENGER SEAT
ASSEMBLY, ITS RELATED COMPONENTS, OR TRIM COVER MAY INADVERTENTLY
CHANGE THE AIRBAG DEPLOYMENT IN CASE OF A FRONTAL CRASH. THIS COULD
RESULT IN DEATH OR SERIOUS INJURY TO THE FRONT SEAT PASSENGER IF THE
VEHICLE IS INVOLVED IN AN ACCIDENT.
The following requirements must be strictly adhered to:
- Do not modify the front passenger seat assembly or components in any way.
- Do not modify the front seat center console or center position seat in any way.
- Do not use prior or future model year seat trim covers not designated for the specific model being
repaired. always use the correct seat trim cover specified for the vehicle.
- Do not replace the seat trim cover with an aftermarket trim cover.
- Do not add a secondary trim cover other than those approved by daimlerchrysler mopar.
- At no time should any supplemental restraint system (srs) component or srs related component or
fastener be modified or replaced with any part except those which are approved by
daimlerchrysler/mopar.
Vehicles with the heated seat option can be visually identified by the two heated seat switches
located in the center stack of the instrument panel. The heated seat system allows the driver and
front seat passenger to select from two different levels of electrical seat heating (HI/LO). The
heated seat system for this vehicle includes the following major components, which are described
in further detail later :
- Heated Seat Switches - Two heated seat switches are used per vehicle. One switch is used for
each front seat. The switches are mounted in the instrument panel, below the radio. Each switch
also includes two Light-Emitting Diode (LED) indicator lamps and an incandescent back lighting
bulb.
- Heated Seat Module - This module contains the solid state electronic control and diagnostic logic
circuitry for the heated seat system. One heated seat module is used per vehicle and is mounted
under the drivers front seat cushion.
- Heated Seat Elements - Four heated seat elements are used per vehicle. One element is used for
each front seat back and one element and sensor assembly is used for each front seat cushion.
The heating elements are integral to the individual front seat and seat back cushions and cannot be
removed once installed at the factory. Replacement seat heating elements are available, without
having to replace the entire seat cushion or trim cover.
- Heated Seat Sensors - Two heated seat sensors are used per vehicle. One heated seat
temperature sensor is used for each front seat cushion. The sensors are integral to the individual
front seat cushion heating elements and cannot be removed once installed at the factory.
Replacement seat heating elements with the sensors are available, without having to replace the
entire seat cushion or trim cover.
The heated seat module receives fused battery current through the Integrated Power Module. The
heated seat switches receive battery current from the Cab Compartment Node (CCN) only when
the ignition switch is in the On position and the engine is running. The heated seat module shares a
common ground circuit with each of the heated seat elements. The heated seat system will control
the surface temperature of the seat cushion to within the designed temperature set points of the
system.
The heated seat system will also automatically turn off whenever the ignition switch is turned to any
position except On, or if the engine quits running. If the ignition switch is turned to the Off position
or if the engine quits running while a heated seat is ON, the heated seat will remain Off after the
engine is restarted until a heated seat switch is depressed again. This helps prevent the vehicles
battery from being drained by the heated seat system.
The heated seat module monitors inputs from the heated seat sensors and the heated seat
switches. In response to these inputs the heated seat module uses its internal programming to
control 12v to the heated seat elements in both front seats and to control the heated seat LED
indicator lamps located in both of the heated seat switches. The heated seat module is also
programmed to provide self-diagnostics, if a problem with the heated seat system is detected. If the
module detects certain failures within the heated seat system, it will provide a visual indication of
the failure by flashing the indicator lamps in the appropriate heated seat switch. The heated seat
module will automatically turn off the heated seat elements if it detects a short or open in the
heated seat element circuit or a heated seat sensor value that is out of range.

Seat Heater: Description and Operation Heated Seat Element
Vehicles equipped with the optional heated seat system have two sets of electrically operated
heating element grids located in each front seat, one set for the seat cushion and the other set for
the seat back. Each of the heated seat element grids consists of a single length of resistor wire that
is routed in a zigzag pattern and captured between a covering and the adhesive foam rubber
backing. Short pigtail wires with connectors are soldered to each end of each resistor wire element
grid, which connect all of the element grids to the heated seat module through the seat wire
harness.
One temperature sensor is used for each front seat, and it is located in the center insert area of the
seat cushion element. The heated seat sensors and their pigtail wires are also captured between a
covering and the adhesive foam rubber backing. The heated seat sensors are Negative Thermal
Coefficient (NTC) thermistors. The sensors for both front seats receive a voltage feed from a single
output of the heated seat module, but the module receives individual sensor inputs from the driver
side and passenger side sensors.
The heated seat elements and sensors should not be repaired. If damaged or faulty, the heated
seat element assembly must be replaced.
One end of the heated seat element resistor wire is connected to ground at all times through a
splice in the heated seat module ground circuit. Battery current is directed to the other end of the
heated seat element resistor wire by the energized N-channel Field Effect Transistor (N-FET)
located within the heated seat module. The heated seat module will energize the N-FET only when
the heated seat switch is in the Low or High position and the heated seat sensor indicates that the
seat cushion surface temperature is below the selected (Low or High) temperature set point. As
electrical current passes through the heating element grid, the resistance of the wire used in the
element disperses some of that electrical current in the form of heat. The heat produced by the
heated seat element grid then radiates through the seat trim cover, warming its occupant.
The resistance of the heated seat sensor increases and decreases as the surface temperature of
the seat cushion cover changes. The heated seat module supplies each sensor with a 5v voltage
feed, then uses the sensor resistance to determine when the heated seat element grids need to be
cycled on or off in order to maintain the selected temperature set point.

Heated Seat Element
Seat Heater: Testing and Inspection Heated Seat Element
The heated seat module will self-diagnose shorted or open heated seat element circuits and sensor
circuits. To manually check the heated seat element, proceed as follows. The wire harness
connectors for the seat cushion and seat back heating elements and sensor are located on the
right side of the seat, near the edge of the seat cushion frame. The proper connector can be
identified by the foam wrapping.
NOTE: When checking heated seat elements for continuity, be certain to move the heating element
being checked. Moving the element, such as sitting in the seat will eliminate the possibility of an
intermittent open in the element which would only be evident if the element was in a certain
position. Failure to check the element in various positions could result in an incomplete test.
1. Position the appropriate seat in the full forward position. 2. Make certain the ignition switch is in
the OFF position. 3. Disconnect the heated seat element connector which requires testing. Check
for continuity between the two heated seat element circuit cavities
while moving the appropriate seat cushion. the appropriate wiring information for the location of
complete heated seat system wiring diagrams. There should be continuity. If OK, the elements
within the seat assembly test OK, go to Step 4. If not OK, replace the inoperative seat heating
element.
4. Test the seat wire harness between the heated seat module connector and the appropriate
heated seat wire harness connector for shorted or open
circuits. If OK, element is OK, proceed with testing the heated seat sensor and module. If not OK,
repair the shorted or open seat wire harness as required.

Seat Heater: Testing and Inspection Heated Seat System
The heated seat system is capable of performing some self-diagnostics. The following table depicts
the various monitored conditions which will be reported to the vehicle operator or technician by
flashing the individual heated seat switch Light Emitting Diode (LED) indicator lamps. Refer to the
HEATED SEAT SYSTEM SELF-DIAGNOSIS table for condition identification. The driver heated
seat switch indicator lamps will flash if a malfunction occurs in the driver heated seat, and the
passenger heated seat switch indicator lamps will flash for a passenger heated seat malfunction. If
a monitored heated seat system malfunction occurs, the switch indicator lamps will flash at a pulse
rate of about one-half second on, followed by about one-half second off for a duration of about one
minute after the switch for the inoperative heated seat is depressed in either the Low or High
direction. This process will repeat every time the inoperative heated seat switch is actuated until
the problem has been corrected.
Heated Seat System Self-diagnosis
Diagnostic logic is built into the heated seat module to help locate the problem by the most efficient
means possible. Anytime a problem is suspected, locate the diagnosis and testing procedure for
the component in question and follow the steps until the specific problem is located and resolved.
Once the problem is thought to be corrected, verify correct system operation. If the heated seat
system is functioning correctly return the vehicle to service.
If a problem could not be verified such as not finding anything wrong when following the diagnostic
procedure, this is a good indication that an INTERMITTENT problem may be present. You must
then attempt to find the intermittent problem, such as moving the heating element within the seat
while testing continuity or wiggling the wire harness's/ electrical connectors under the seat while
testing continuity. Always, eliminate all other potential problems before attempting to replace the
heated seat module.
PRELIMINARY TEST
Refer to Wiring for the location of complete heated seat system wiring diagrams. Before testing the
individual components in the heated seat system, perform the following preliminary checks:
WARNING: DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL,
STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
DISCONNECT AND ISOLATE THE BATTERY NEGATIVE CABLE, THEN WAIT TWO MINUTES
FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER
DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
- If the heated seat switch back lighting and the cluster illumination lamps do not illuminate with the
headlamps or park lamps turned On, refer to the Instrument Cluster for the location of cluster
illumination lamp diagnosis and testing procedures. If the heated seat switch back lighting does not
illuminate, but the cluster illumination lamps do illuminate with the headlamps or park lamps turned
On.
- If a single LED indicator lamp for one heated seat switch does not operate and the heated seat
elements do heat, refer to testing for the heated seat switch diagnosis and testing procedures.
- If both LED indicator lamps for a heated seat switch operate, but the heated seat elements do not
heat.
- If the indicator lamp on either heated seat switch remains illuminated after the heated seat has
been turned Off.

Seat Heater Control Module: Description and Operation
The heated seat module (2) is also known as the Seat Heat Interface Module. The heated seat
module is located under the drivers front seat cushion, where it is secured to a mounting bracket.
The heated seat module has a single connector receptacle (3) that allows the module to be
connected to all of the required inputs and outputs through the seat wire harness.
The heated seat module is an electronic microprocessor controlled device designed and
programmed to use inputs from the battery, the two heated seat switches and the two heated seat
sensors to operate and control the heated seat elements in both front seats and the two heated
seat indicator lamp Light-Emitting Diodes (LEDs) in each heated seat switch. The heated seat
module is also programmed to perform self-diagnosis of certain heated seat system functions and
provide feedback of that diagnosis through the heated seat switch indicator lamps.
The heated seat module cannot be repaired. If the heated seat module is damaged or faulty, the
entire module must be replaced.
The heated seat module operates on fused battery current received from the integrated power
module. Inputs to the module include a resistor multiplexed heated seat switch request circuit for
each of the two heated seat switches and the heated seat sensor inputs from the seat cushions of
each front seat. In response to those inputs the heated seat module controls battery current feeds
to the heated seat elements and sensors, and controls the ground for the heated seat switch
indicator lamps.
When a heated seat switch (Driver or Passenger) is depressed a signal is received by the heated
seat module, the module energizes the proper indicator LED (Low or High) in the switch by
grounding the indicator lamp circuit to indicate that the heated seat system is operating. At the
same time, the heated seat module energizes the selected heated seat sensor circuit and the
sensor provides the module with an input indicating the surface temperature of the selected seat
cushion.
The Low heat set point is about 36° C (96.8° F), and the High heat set point is about 42° C (107.6°
F). If the seat cushion surface temperature input is below the temperature set point for the selected
temperature setting, the heated seat module energizes an N-channel Field Effect Transistor
(N-FET) within the module which energizes the heated seat elements in the selected seat cushion
and back. When the sensor input to the module indicates the correct temperature set point has
been achieved, the module de-energizes the N-FET which de-energizes the heated seat elements.
The heated seat module will continue to cycle the N-FET as needed to maintain the selected
temperature set point.
If the heated seat module detects a heated seat sensor value input that is out of range or a shorted
or open heated seat element circuit, it will notify the vehicle operator or the repair technician of this
condition by flashing the High and/or Low indicator lamps in the affected heated seat switch.

Seat Heater Sensor: Description and Operation
The heated seat temperature sensor is a Negative Temperature Coefficient (NTC) thermistor. One
temperature sensor is used for each seat. This temperature sensor is located in the seat cushion
heating element on all models.
The heated seat temperature sensor cannot be repaired or adjusted and must be replaced if
inoperative. The heated seat temperature sensor is part of the heated seat cushion element and
must be replaced as an assembly.
When the temperature of the seat cushion cover rises, the resistance of the sensor decreases. The
heated seat module supplies five-volts to one side of each sensor, and monitors the voltage drop
through the sensor on a return circuit. The heated seat module uses this temperature sensor input
to monitor the temperature of the seat, and regulates the current flow to the seat heating elements
accordingly.

Seat Heater Switch: Description and Operation
The momentary, bidirectional rocker-type heated seat switch (1) provides a resistor-multiplexed
signal to the heated seat module via a mux circuit. Each switch has a center neutral position and
momentary Low and High positions so that both the driver and the front seat passenger can select
a preferred level of seat heating. Each heated seat switch has two Light-Emitting Diode (LED)
indicator lamps (2), which indicate the selected mode (Low or High) of the seat heater. These
indicator lamps also provide diagnostic feedback for the heated seat system. Each switch also has
an incandescent bulb, which provides dimmer controlled back lighting of the switch when the
headlamps or park lamps are on.
The heated seat switches are both mounted in the instrument panel center bezel, located in the
lower center of the instrument panel. The two switches are snapped into the mounting holes of the
heated seat switch bezel, and the heated seat switch bezel is secured with screws to the
instrument panel center bezel. The heated seat switches are differentiated by the keyway in the
connector receptacle on the backs of the switches and keyway on the switch housing. The
instrument panel wire harness connectors for the heated seat switches are keyed to match the
connector receptacles on the switches so that the two heated seat switches can only be connected
to the proper heated seat electrical.
The two LED indicator lamps and the incandescent bulb in each heated seat switch cannot be
repaired. If the indicator lamps or back lighting bulb are faulty or damaged, the individual heated
seat switch must be replaced.
The heated seat switches receive battery current through a fused ignition switch output (run) circuit
when the ignition switch is in the On position. Depressing the heated seat switch rocker to its
momentary High or Low position provides a hard-wired resistance signal to the heated seat
module. This signal tells the module to energize the heated seat element of the selected seat and
maintain the requested temperature setting. If the heated seat switch is depressed to a different
position (Low or High) than the currently selected state, the heated seat module will change states
to support the new selection. If a heated seat switch is depressed a second time, the heated seat
module interprets the second input as a request to turn the seat heater OFF.
The High and Low LED indicator lamps in the heated seat switches receive battery current through
a fused ignition switch output (run) circuit when the ignition switch is in the On position. The ground
side of each indicator lamp is controlled by the heated seat module. This control of the switch
indicator lamps also allows the module to provide diagnostic feedback to the vehicle operator or
technician to indicate heated seat system faults by flashing the indicator lamps on and off. One
side of the incandescent back lighting bulb in each heated seat switch is connected to ground at all

Seat Track: Description and Operation
The eight-way power seat option includes a power seat track assembly (1) located under each front
seat. The power seat track assembly replaces the standard manually operated seat tracks. The
lower half of the power seat track is secured at the front with two bolts to the floor panel seat cross
member, and at the rear with two bolts to the floor panel. Four nuts secure the bottom of the seat
cushion frame to the upper half of the power seat track unit.
The power seat track assembly cannot be repaired, and is serviced only as a complete assembly. If
any component in this assembly is inoperative or damaged, the entire power seat track must be
replaced.
The power seat track unit includes three reversible electric motors that are secured to the upper
half of the track unit. Each motor moves the seat adjuster through a combination of worm-drive
gearboxes and screw-type drive units.
The front and rear of the seat are operated by two separate vertical adjustment motors. These
motors can be operated independently of each other, tilting the entire seat assembly forward or
rearward; or, they can be operated in unison by selecting the proper power seat switch functions,
which will raise or lower the entire seat assembly. The third motor is the horizontal adjustment
motor, which moves the seat track in the forward and rearward directions.

Door Position Switch: Description and Operation
Vehicles that are equipped with the optional Vehicle Theft Security System (VTSS) have a door
cylinder lock switch (1) secured to the back of the key lock cylinder inside the driver side front door.
The door cylinder lock switch is a resistor multiplexed momentary switch that is hard wired in series
between ground and the cylinder lock switch mux circuit input to the ElectroMechanical Instrument
Cluster (EMIC) through a pigtail wire (2) connected to the left front door wire harness. The door
cylinder lock switch is driven by the key lock cylinder and contains two internal resistors. One
resistor value is used for the Lock position, and one for the Unlock position.
The door cylinder lock switch cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.
The door cylinder lock switch is actuated by the key lock cylinder when the key is inserted in the
lock cylinder and turned to the lock or unlock positions. The door cylinder lock switch closes a
circuit between ground and the cylinder lock switch mux circuit through one of two internal resistors
for the ElectroMechanical Instrument Cluster (EMIC) when the driver side front door key lock
cylinder is in the Lock, or Unlock positions. The EMIC reads the switch status through an internal
pull-up, then uses this information as an input for the Vehicle Theft Security System (VTSS)
operation, as well as for control of a central locking feature for the power lock system.
The door cylinder lock switch and circuit may be diagnosed using conventional diagnostic tools and
methods. However, conventional diagnostic methods may not prove conclusive in the diagnosis of
the EMIC or its responses to the cylinder lock switch inputs. The most reliable, efficient, and
accurate means to diagnose the door cylinder lock switch, the EMIC, and both the hard wired and
electronic message inputs and outputs affected by the door cylinder lock switch inputs requires the
use of a diagnostic scan tool.

Power Door Lock Switch: Description and Operation
A window/lock switch is used on all models equipped with power locks, power windows, and power
mirrors. The window/lock switch houses the following switches:
- Power Lock Switch - A two-way, momentary, resistor multiplexed switch to control the power lock
system.
- Power Mirror Selector Switch - A three-position rocker switch selects the right or left power mirror
for adjustment, or turns the power mirror system Off.
Power Mirror Adjustment Switches - Four momentary, arrowhead shaped, directional switches
allow the driver to adjust the selected power mirror in the Up, Down, Right, or Left directions.
- Power Window Lockout Switch - A two-way, latching, push-button switch allows the vehicle
operator to lock out the power window switches on each passenger door so that the passenger
door power windows may be operated only from the master switches.
- Power Window Switches - A two-way, momentary power window switch for the driver side front
door. This switch also has a second detent in the Down direction and internal circuitry to provide an
Auto-Down feature for the driver side front door power window. In addition to the power window
switch for its own door, there are individual master switches for each passenger door power
window.
The window/lock switch also incorporates several green Light-Emitting Diodes (LEDs) that
illuminate the power lock and power window switch paddles, and the power mirror switch
directional buttons to improve switch visibility.
The window/lock switch combines a power lock switch, a driver power window switch with an
Auto-down feature, master switches for each passenger door power window, a power window
lockout switch, a power mirror selector switch, and four power mirror adjustment switches in a
single unit.
Power Lock Switch
The power lock switch circuitry is connected in series between ground and the driver door switch
mux input of the instrument cluster. Each power lock switch position (Lock, Unlock, and Neutral)
provides a different resistance value to the instrument cluster input, which allows the instrument
cluster to sense the switch position. Based upon the power lock switch input, the instrument cluster
controls the battery and ground feed outputs to the individual power lock motors to lock or unlock
the door latches. The Light-Emitting Diode (LED) in the power lock switch is connected to battery
current through the power window circuit breaker in the Integrated Power Module (IPM) on a fused
ignition switch output (run-acc) circuit. The switch will be illuminated whenever the ignition switch is
in the On or Accessory positions.
Power Window Switches
The power window switch circuitry is connected to battery current through a circuit breaker in the
Integrated Power Module (IPM) on a fused ignition switch output (run-acc) circuit so that the power
windows will operate whenever the ignition switch is in the On or Accessory positions. Each
two-way, momentary master passenger power window switch provides battery current and ground
to the individual power window switches on each passenger door so that the power window switch
controls the battery current and ground feeds to its respective power window motor. The switch for
the driver side front door power window is labeled "Auto" and includes an auto-down feature. When
this switch is depressed to a second momentary detent position and released, the driver door
power window is automatically operated through an internal circuit and relay to its fully lowered
position. The Auto-down event is cancelled if the switch paddle is depressed a second time in
either the Up or Down direction. When the two position window lockout switch is depressed and
latched in the lockout position, the battery current feed to each of the individual passenger power
window switches is interrupted so that the passenger door power windows can only be operated
from the master switches. The window lockout switch also controls the battery current feed for the
LED in each passenger power window switch so that the switch will not be illuminated when it is
locked out.
Power Mirror Switches
The power mirror switch circuitry is connected to battery current through a fuse in the IPM on a
fused B(+) circuit so that the power mirrors remain operational regardless of the ignition switch
position. A rocker type selector switch has three positions, one to select the right mirror, one to
select the left mirror, and a neutral Off position. After the right or left mirror is selected, one of four
directional buttons is depressed to move the selected mirror Up, Down, Right or Left. The power
mirror switch circuitry controls the battery current and ground feeds to each of the four (two in each
mirror head) power mirror motors. The Light-Emitting Diode (LED) in the power mirror switch is
connected to battery current through the power window circuit breaker in the IPM on a fused
ignition switch output (run-acc) circuit so that the switch directional buttons will be illuminated
whenever the ignition switch is in the On or Accessory positions.

Power Seat Switch: Description and Operation
The power seats on this vehicle can be adjusted in eight different directions, up, down, front up,
front down, rear up, rear down, rearward and forward. The power seat switch is located on the
outboard side of the seat cushion on the seat cushion side shield.
The individual switches in the power seat switch assembly cannot be repaired. If one switch is
damaged or inoperative, the entire power seat switch assembly must be replaced.
When a power switch control knob or knobs are actuated, a battery feed and a ground path are
applied through the switch contacts to the power seat track adjuster motor. The selected adjuster
motor operates to move the seat track or recliner through its drive unit in the selected direction until
the switch is released, or until the travel limit of the adjuster is reached. When the switch is moved
in the opposite direction, the battery feed and ground path to the motor are reversed through the
switch contacts. This causes the adjuster motor to run in the opposite direction.
No power seat switch should be held applied in any direction after the adjuster has reached its
travel limit. The power seat adjuster motors each contain a self-resetting circuit breaker to protect
them from overload. However, consecutive or frequent resetting of the circuit breaker must not be
allowed to continue, or the motor may be damaged.

Seat Heater Sensor: Description and Operation
The heated seat temperature sensor is a Negative Temperature Coefficient (NTC) thermistor. One
temperature sensor is used for each seat. This temperature sensor is located in the seat cushion
heating element on all models.
The heated seat temperature sensor cannot be repaired or adjusted and must be replaced if
inoperative. The heated seat temperature sensor is part of the heated seat cushion element and
must be replaced as an assembly.
When the temperature of the seat cushion cover rises, the resistance of the sensor decreases. The
heated seat module supplies five-volts to one side of each sensor, and monitors the voltage drop
through the sensor on a return circuit. The heated seat module uses this temperature sensor input
to monitor the temperature of the seat, and regulates the current flow to the seat heating elements
accordingly.

Seat Heater Switch: Description and Operation
The momentary, bidirectional rocker-type heated seat switch (1) provides a resistor-multiplexed
signal to the heated seat module via a mux circuit. Each switch has a center neutral position and
momentary Low and High positions so that both the driver and the front seat passenger can select
a preferred level of seat heating. Each heated seat switch has two Light-Emitting Diode (LED)
indicator lamps (2), which indicate the selected mode (Low or High) of the seat heater. These
indicator lamps also provide diagnostic feedback for the heated seat system. Each switch also has
an incandescent bulb, which provides dimmer controlled back lighting of the switch when the
headlamps or park lamps are on.
The heated seat switches are both mounted in the instrument panel center bezel, located in the
lower center of the instrument panel. The two switches are snapped into the mounting holes of the
heated seat switch bezel, and the heated seat switch bezel is secured with screws to the
instrument panel center bezel. The heated seat switches are differentiated by the keyway in the
connector receptacle on the backs of the switches and keyway on the switch housing. The
instrument panel wire harness connectors for the heated seat switches are keyed to match the
connector receptacles on the switches so that the two heated seat switches can only be connected
to the proper heated seat electrical.
The two LED indicator lamps and the incandescent bulb in each heated seat switch cannot be
repaired. If the indicator lamps or back lighting bulb are faulty or damaged, the individual heated
seat switch must be replaced.
The heated seat switches receive battery current through a fused ignition switch output (run) circuit
when the ignition switch is in the On position. Depressing the heated seat switch rocker to its
momentary High or Low position provides a hard-wired resistance signal to the heated seat
module. This signal tells the module to energize the heated seat element of the selected seat and
maintain the requested temperature setting. If the heated seat switch is depressed to a different
position (Low or High) than the currently selected state, the heated seat module will change states
to support the new selection. If a heated seat switch is depressed a second time, the heated seat
module interprets the second input as a request to turn the seat heater OFF.
The High and Low LED indicator lamps in the heated seat switches receive battery current through
a fused ignition switch output (run) circuit when the ignition switch is in the On position. The ground
side of each indicator lamp is controlled by the heated seat module. This control of the switch
indicator lamps also allows the module to provide diagnostic feedback to the vehicle operator or
technician to indicate heated seat system faults by flashing the indicator lamps on and off. One
side of the incandescent back lighting bulb in each heated seat switch is connected to ground at all
times. The other side of the incandescent bulb is connected to the fused panel lamps dimmer
switch signal circuit. These bulbs are energized when the park lamps or headlamps are turned on,
and their illumination intensity is controlled by the panel lamps dimmer switch.

ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
1. If the problem being diagnosed involves inoperative heated seat switch back lighting and the
cluster illumination lamps operate, go to Step 2. If the
problem being diagnosed involves inoperative heated seat switch back lighting and the cluster
illumination lamps are also inoperative, Refer to electrical/instrument cluster - diagnosis and
testing. If the problem being diagnosed involves inoperative heated seat switch indicator lamps and
the heated seat elements do not heat, proceed. If the problem being diagnosed involves
inoperative heated seat switch indicator lamps and the heated seat elements do heat, go to Step 6.
If the problem being diagnosed involves a heated seat switch indicator lamp that remains
illuminated after the heated seat has been turned Off, Refer to electrical/electronic control
modules/memory heated seat/mirror module - diagnosis and testing.
2. Disconnect and isolate the battery negative cable. Remove the heated seat switch and bezel unit
from the instrument panel. Disconnect the heated
seat switch to be tested. Check for continuity between the ground circuit cavity of the heated seat
switch and a good ground. There should be continuity. If OK, go to Step 3. If not OK, repair the
open ground circuit to ground as required.
3. Reconnect the battery negative cable. Turn the park lamps on with the headlamp switch. Rotate
the panel lamps dimmer thumb wheel on the
headlamp switch upward to just before the interior lamps detent. Check for battery voltage at the
fused panel lamps dimmer circuit cavity of the heated seat switch. If OK, go to Step 4. If not OK,
repair the open fused panel lamps dimmer switch signal circuit to the fuse in the Integrated Power
Module as required.
4. Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch
output (run) circuit cavity of the heated seat
switch. If OK, go to Step 5. If not OK, repair the open fused ignition switch output (run) circuit as
required.
Heated Seat Switch Continuity
5. Check the continuity and resistance values of the heated seat switch in the Neutral, Low and
High positions as shown in the Heated Seat Switch
Continuity chart. If OK, refer to Step 6. If not OK, replace the faulty heated seat switch.
6. Replace the inoperative heated seat switch with a known good unit and test the operation of the
switch indicator lamps. If OK, discard the faulty
heated seat switch. If not OK, Refer to electrical/electronic control modules/memory heated
seat/mirror module - diagnosis and testing.

Cruise Control Switch: Description and Operation
Two separate switch pods operate the speed control system. The steering-wheel-mounted
switches use multiplexed circuits to provide inputs to the PCM (to the ECM for diesel) for ON, OFF,
RESUME, ACCELERATE, SET, DECEL and CANCEL modes.
The individual switches cannot be repaired. If one switch fails, the entire switch module must be
replaced.
Depending on engine control computer (JTEC having a 3- plug connector or NGC having a 4- plug
connector), 2 types of switches are used. Both types of switches are internally and externally
different. The switch used with the NGC system has an attached pigtail lead. The switch used with
the JTEC system does not have an attached pigtail lead.
When speed control is selected by depressing the ON, OFF switch, the PCM (ECM for diesel)
allows a set speed to be stored in its RAM for speed control. To store a set speed, depress the
SET switch while the vehicle is moving at a speed between approximately 35 and 85 mph. In order
for the speed control to engage, the brakes cannot be applied, nor can the gear selector be
indicating the transmission is in Park or Neutral.
The speed control can be disengaged manually by:
- Stepping on the brake pedal
- Depressing the OFF switch
- Depressing the CANCEL switch.
The speed control can be disengaged also by any of the following conditions:
- An indication of Park or Neutral (auto. trans.)
- The VSS signal increases at a rate of 10 mph per second (indicates that the co-efficient of friction
between the road surface and tires is extremely low)
- Depressing the clutch pedal (manual trans.).
- Excessive engine rpm (indicates that the transmission may be in a low gear)
- The VSS signal decreases at a rate of 10 mph per second (indicates that the vehicle may have
decelerated at an extremely high rate)
- If the actual speed is not within 20 mph of the set speed The previous disengagement conditions
are programmed for added safety.
Once the speed control has been disengaged, depressing the ACCEL switch restores the vehicle
to the target speed that was stored in the PCM's RAM (ECM for diesel).
NOTE: Depressing the OFF switch will erase the set speed stored in the PCM's/ECM's RAM.
If, while the speed control is engaged, the driver wishes to increase vehicle speed, the PCM (ECM
for diesel) is programmed for an acceleration feature. With the ACCEL switch held closed, the
vehicle accelerates slowly to the desired speed. The new target speed is stored in the
PCM's/ECM's RAM when the ACCEL switch is released. The PCM/ECM also has a "tap-up"
feature in which vehicle speed increases at a rate of approximately 2 mph for each momentary
switch activation of the ACCEL switch.
The PCM/ECM also provides a means to decelerate without disengaging speed control. To
decelerate from an existing recorded target speed, depress and hold the COAST switch until the
desired speed is reached. Then release the switch. The ON, OFF switch operates two
components: the PCM's/ECM's ON, OFF input, and the battery voltage to the brake switch.

Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > ABS Light > Component Information >
Description and Operation
ABS Light: Description and Operation
An Antilock Brake System (ABS) indicator is standard equipment on all instrument clusters.
However, the instrument cluster can be programmed to disable this indicator on vehicles that are
not equipped with the ABS or Rear Wheel Anti-Lock (RWAL) brake systems, which are not
available in some markets. On vehicles equipped with a gasoline engine, the ABS indicator is
located near the lower edge of the instrument cluster, between the tachometer and the
speedometer. On vehicles equipped with a diesel engine, the ABS indicator is located on the right
side of the instrument cluster, to the right of the engine temperature gauge.
The ABS indicator consists of a stencil-like cutout of the International Control and Display Symbol
icon for "Failure of Anti-lock Braking System" in the opaque layer of the instrument cluster overlay.
The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not
illuminated. An amber Light Emitting Diode (LED) behind the cutout in the opaque layer of the
overlay causes the icon to appear in amber through the translucent outer layer of the overlay when
the indicator is illuminated from behind by the LED, which is soldered onto the instrument cluster
electronic circuit board. The ABS indicator is serviced as a unit with the instrument cluster.
The ABS indicator gives an indication to the vehicle operator when the ABS system is faulty or
inoperative. This indicator is controlled by a transistor on the instrument cluster circuit board based
upon cluster programming and electronic messages received by the cluster from the Controller
Antilock Brake (CAB) over the Programmable Communications Interface (PCI) data bus.
The ABS indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster
logic circuit, and that logic will only allow this indicator to operate when the instrument cluster
receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the
LED will always be off when the ignition switch is in any position except On or Start. The LED only
illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument
cluster will turn on the ABS indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the ABS indicator is
illuminated for about four seconds as a bulb test. The entire bulb test is a function of the CAB.
- ABS Lamp-On Message - Each time the cluster receives a lamp-on message from the CAB, the
ABS indicator will be illuminated. The indicator remains illuminated until the cluster receives a
lamp-off message from the CAB, or until the ignition switch is turned to the Off position, whichever
occurs first.
- Communication Error - If the cluster receives no lamp-on or lamp-off messages from the CAB for
five consecutive message cycles, the ABS indicator is illuminated. The indicator remains
illuminated until the cluster receives a valid message from the CAB, or until the ignition switch is
turned to the Off position, whichever occurs first.
- Actuator Test - Each time the instrument cluster is put through the actuator test, the ABS indicator
will be turned on, then off again during the bulb check portion of the test to confirm the functionality
of the LED and the cluster control circuitry.
- ABS Diagnostic Test - The ABS indicator is blinked on and off by lamp-on and lamp-off messages
from the CAB during the performance of the ABS diagnostic tests.
The CAB continually monitors the ABS circuits and sensors to decide whether the system is in
good operating condition. The CAB then sends the proper lamp-on or lamp-off messages to the
instrument cluster. If the CAB sends a lamp-on message after the bulb test, it indicates that the
CAB has detected a system malfunction and/or that the ABS system has become inoperative. The
CAB will store a Diagnostic Trouble Code (DTC) for any malfunction it detects. Each time the ABS
indicator fails to light due to an open or short in the cluster ABS indicator circuit, the cluster sends a
message notifying the CAB of the condition, then the instrument cluster and the CAB will each
store a DTC.
For proper diagnosis of the antilock brake system, the CAB, the PCI data bus, or the electronic
message inputs to the instrument cluster that control the ABS indicator, a diagnostic scan tool is
required.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component
Information > Diagrams > Diagram Information and Instructions > Page 7682
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Information > Diagrams > Diagram Information and Instructions > Page 7685
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component
Information > Diagrams > Page 7703
Audible Warning Device: Description and Operation
A chime warning system is standard factory-installed equipment. The chime warning system uses
an electromechanical transducer and an electromechanical relay that are soldered onto the
electronic circuit board inside of the ElectroMechanical Instrument Cluster (EMIC) (1) to provide
audible indications of various vehicle conditions that may require the attention of the vehicle
operator or occupants. The EMIC also includes the hardware and software necessary to serve as
the electronic body control module and is sometimes referred to as the Cab Compartment Node or
CCN.
The electromechanical transducer generates beep tones and chime tones, while the
electromechanical relay generates click tones to emulate the sounds associated with conventional
turn signal and hazard warning flasher operation. The microprocessor-based EMIC utilizes
electronic chime request messages received from other modules in the vehicle over the
Programmable Communications Interface (PCI) data bus network along with hard wired inputs to
monitor many sensors and switches throughout the vehicle. In response to those inputs, the
circuitry and programming of the EMIC allow it to control the audible outputs that are produced
through its on-board transducer and relay.
The EMIC is capable of producing the following audible outputs:
- Slow Rate Repetitive Click - Repeated "click" tones that are issued at a slow rate of about 50
clicks per minute.
- Fast Rate Repetitive Click - Repeated "click" tones that are issued at a fast rate of more than
about 100 clicks per minute.
- Fixed Duration Beep - A short, sharp, single tactile "beep" tone.
- Single Chime Tone - A single "chime" tone.
- Slow Rate Repetitive Chime - Repeated "chime" tones that are issued at a slow rate of about 50
chimes per minute.
- Fast Rate Repetitive Chime - Repeated "chime" tones that are issued at a fast rate of about 180
chimes per minute.
Hard wired circuitry connects the EMIC and the various chime warning system switch and sensor
inputs to their modules and to each other through the electrical system of the vehicle. These hard
wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and
retained by many different methods. These circuits may be connected to each other, to the vehicle
electrical system and to the EMIC through the use of a combination of soldered splices, splice
block connectors, and many different types of wire harness terminal connectors and insulators. The
wiring information includes wiring diagrams, proper wire and connector repair procedures, further
details on wire harness routing and retention, as well as pin-out and location views for the various
wire harness connectors, splices and grounds.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component
Information > Diagrams > Page 7704
The EMIC chime warning system circuits and components cannot be adjusted or repaired. If the
EMIC circuitry, the on-board transducer or the relay are damaged or faulty, the EMIC unit must be
replaced.
The chime warning system operates on battery voltage received through the Ignition-Off Draw
(IOD) fuse in the Power Distribution Center (PDC) on a non-switched fused B(+) circuit so that the
system may operate regardless of the ignition switch position. The chime warning system also
monitors the ignition switch position so that some chime features are functional only with the
ignition switch in the On position, while others are functional regardless of the ignition switch
position.
The chime warning system provides an audible indication to the vehicle operator or occupants
under the following conditions:
- Airbag Indicator Warning - The ElectroMechanical Instrument Cluster (EMIC) transducer will
generate one short chime when the ignition switch is in the On position, and an electronic message
is received over the Programmable Communications Interface (PCI) data bus from the Airbag
Control Module (ACM) requesting "Airbag" indicator illumination. This warning will only occur
following completion of the "Airbag" indicator bulb test, and will only occur once during any ignition
cycle.
- Compass Mini-Trip Computer Global Reset - The EMIC transducer will generate one short chime
when the ignition switch is in the On position, and an electronic message is received over the PCI
data bus from the optional Compass Mini-Trip Computer (CMTC) requesting that the CMTC
average fuel economy, trip odometer and distance to empty data be reset. The CMTC monitors
hard wired inputs from the U.S./Metric and Reset button switches to determine the proper reset
messages to send to the EMIC.
Door Ajar Indicator Warning - The EMIC transducer will generate one short chime when the ignition
switch is in the On position, a hard wired input is received indicating that the status of any door ajar
switch has changed, and an electronic message is received over the PCI data bus indicating that
the vehicle is moving.
- Engine Coolant Temperature High Warning (Diesel Engine Only) - The EMIC transducer will
generate a single chime tone when the "Check Gauges" indicator is illuminated for a high or critical
engine coolant temperature condition. The instrument cluster uses engine coolant temperature
message inputs received from the diesel Engine Control Module (ECM) over the PCI data bus to
illuminate the "Check Gauges" indicator for a coolant temperature high condition.
- Fasten Seat Belt Indicator Warning - The EMIC transducer will generate repetitive chimes at a
slow rate to announce that a hard wired input from the seat belt switch indicates that the driver side
front seat belt is not fastened with the ignition switch in the On position. The chime warning system
also supports the enhanced seatbelt reminder (beltminder) when this feature is enabled.
- Head/Park Lamps-On Warning - The EMIC transducer will generate repetitive chimes at a fast
rate to indicate that hard wired inputs from the driver door ajar switch, the headlamp switch, and
the ignition switch indicate that the exterior lamps are turned On with the driver side front door
opened and the ignition switch in the Off position. The chimes will continue to sound until the
exterior lamps are turned Off, the driver side front door is closed, or the ignition switch is turned to
the On position, or the battery saver (load shed) time-out expires, whichever occurs first.
- Key-In-Ignition Warning - The EMIC transducer will generate repetitive chimes at a fast rate to
announce that the hard wired inputs from the driver door ajar switch, the ignition switch, and the
key-in ignition switch circuitry of the ignition switch indicate that the key is in the ignition lock
cylinder with the driver side front door open and the ignition switch in the Off position. The chimes
will continue to sound until the key is removed from the ignition lock cylinder, the driver side front
door is closed, or the ignition switch is turned to the On position, whichever occurs first.
- Low Fuel Indicator Warning - The EMIC transducer will generate one short chime tone when the
"Low Fuel" indicator is illuminated by the instrument cluster circuitry. This chime will only occur
once during any ignition cycle.
- Low Oil Pressure Warning (Diesel Engine Only) - The EMIC transducer will generate repetitive
chimes at a fast rate when the "Check Gauges" indicator is illuminated for a low oil pressure
condition. The instrument cluster uses engine speed and oil pressure message inputs received
from the diesel Engine Control Module (ECM) over the PCI data bus indicating that the engine is
running and that the oil pressure is low to illuminate the "Check Gauges" indicator. The chimes will
continue to sound for five seconds, until the engine oil pressure message indicates that the oil
pressure is not low, or until the engine speed message indicates that the engine is not running,
whichever occurs first. This chime will only occur once during any ignition cycle.
- Low Wash Indicator Warning - The EMIC transducer will generate one short chime when the "Low
Washer Fluid" indicator is illuminated by the instrument cluster circuitry. This chime will only occur
once during any ignition cycle.
- Overspeed Warning - The EMIC transducer will generate repetitive chimes at a slow rate to
indicate that the vehicle speed is over a pre-programmed speed value. The EMIC monitors
electronic vehicle speed messages received over the PCI data bus. This feature is only enabled on
an EMIC that has been programmed with a Middle East Gulf Coast Country (GCC) country code.
- Park Brake Reminder - The EMIC transducer will generate ten repetitive chimes at a slow rate to
announce that the hard wired input from the park brake switch and a vehicle speed message input
received over the PCI data bus indicate that the park brake is applied and the vehicle is moving.
This chime will repeat each time the input conditions are met.
- Sentry Key "Customer Learn" Mode Announcement - The EMIC transducer will generate one
short chime to confirm that an electronic "Customer Learn" mode message has been received over
the PCI data bus to indicate the Sentry Key Immobilizer Module (SKIM) is prepared for
programming additional sentry key transponders. This chime feature is only active on vehicles
equipped with the optional Sentry Key Immobilizer System (SKIS), and sold in markets where
"Customer Learn" programming is an allowed feature.
- Trans Overtemp Indicator Warning (Automatic Transmission Only) - The EMIC transducer will
generate repetitive chimes at a slow rate when the "Trans Temp" indicator is illuminated by the
instrument cluster circuitry for a high or critical transmission fluid temperature condition. This chime
will repeat each time the trans overtemp indicator is cycled from Off to On.
- Turn Signal/Hazard Warning Flasher Emulation - The EMIC relay will generate repetitive clicks at
a slow rate to emulate an electromechanical flasher when the turn signal or hazard warning system
are operating. The EMIC relay will generate repetitive clicks at a fast rate to indicate that the right
or left turn signal are operating with one or more bulbs inoperative. In either case, the clicks will
continue until the turn signal and hazard warning systems are turned off.
- Turn Signal On Warning - The EMIC transducer will generate repetitive chimes at a slow rate to
indicate that a turn signal has been active continuously for 1.6 kilometers (1 mile) with the vehicle
speed greater than 22 kilometers-per-hour (15 miles-per hour). Vehicles built for markets other
than the United States and Canada have a revised distance threshold of 4 kilometers for this
feature. The chime will continue until
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component
Information > Diagrams > Page 7705
the turn signal input becomes inactive or until the vehicle speed message indicates that the speed
is less than 22 kilometers-per-hour (15 miles-per-hour), whichever occurs first. The hazard warning
flashers will not activate this chime feature.
- Warning Indicator Announcement - The EMIC transducer will generate one short chime each time
the "Check Gauges" indicator is illuminated by the instrument cluster circuitry. The "Check Gauges"
indicator may be illuminated when any critical engine or transmission systems are operating
outside of their normal parameters. The instrument cluster monitors electronic messages received
over the PCI data bus to determine when to illuminate the "Check Gauges" indicator.
The EMIC provides chime service for all available features in the chime warning system. The EMIC
relies upon its internal programming, numerous hard wired inputs, and electronic message inputs
received from other modules over the PCI data bus network to provide the chime warning system
features. The internal programming of the EMIC determines the priority of each chime request input
that is received, as well as the rate and duration of each chime that is to be generated.
The hard wired chime warning system inputs to the EMIC may be diagnosed and tested using
conventional diagnostic tools and methods. However, conventional diagnostic methods may not
prove conclusive in the diagnosis of the EMIC, the PCI data bus, or the electronic messages
received by the EMIC from other modules for control of the chime warning system. The most
reliable, efficient and accurate means to diagnose the EMIC, the PCI data bus, or the electronic
message inputs used for the chime warning system requires the use of a diagnostic scan tool.

Check Gauges Lamp: Description and Operation
A check gauges indicator is standard equipment on all instrument clusters. On vehicles equipped
with a gasoline engine, the check gauges indicator is located near the lower edge of the instrument
cluster, between the tachometer and the speedometer. On vehicles equipped with a diesel engine,
the check gauges indicator is located on the left side of the instrument cluster, to the left of the
voltage gauge.
The check gauges indicator consists of a stencil-like cutout of the words "CHECK GAGES" in the
opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents the
indicator from being clearly visible when it is not illuminated. A red Light Emitting Diode (LED)
behind the cutout in the opaque layer of the overlay causes the "CHECK GAGES" text to appear in
red through the translucent outer layer of the overlay when the indicator is illuminated from behind
by the LED, which is soldered onto the instrument cluster electronic circuit board. The check
gauges indicator is serviced as a unit with the instrument cluster.
The check gauges indicator gives an indication to the vehicle operator when certain instrument
cluster gauge readings reflect a condition requiring immediate attention. This indicator is controlled
by a transistor on the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) on vehicles
equipped with a gasoline engine, or from the Engine Control Module (ECM) on vehicles equipped
with a diesel engine over the Programmable Communications Interface (PCI) data bus.
The check gauges indicator Light Emitting Diode (LED) is completely controlled by the instrument
cluster logic circuit, and that logic will only allow this indicator to operate when the instrument
cluster receives a battery current input on the fused ignition switch output (run-start) circuit.
Therefore, the LED will always be off when the ignition switch is in any position except On or Start.
The LED only illuminates when it is provided a path to ground by the instrument cluster transistor.
The instrument cluster will turn on the check gauges indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the check gauges indicator is
illuminated for about two seconds as a bulb test.
- Engine Temperature High Message - Each time the cluster receives three consecutive bus
messages from the PCM or ECM indicating the engine coolant temperature of a gasoline engine is
about 122° C (252° F) or higher, or of a diesel engine is about 112° C (233° F) or higher, the check
gauges indicator will be illuminated and a single chime is sounded. The indicator remains
illuminated until the cluster receives a message from the PCM or ECM indicating that the engine
coolant temperature of a gasoline engine is below about 122° C (252° F), or of a diesel engine is
below about 112° C (233° F), or until the ignition switch is turned to the Off position, whichever
occurs first.
- Engine Oil Pressure Low Message - Each time the cluster receives three consecutive bus
messages from the PCM or ECM indicating the engine oil pressure is about 41 kPa (6 psi) or lower,
the check gauges indicator will be illuminated and a single chime is sounded. The indicator remains
illuminated until the cluster receives a message from the PCM or ECM indicating that the engine oil
pressure is above about 41 kPa (6 psi), or until the ignition switch is turned to the Off position,
whichever occurs first. The cluster will only turn the indicator on in response to an engine oil
pressure low message if the engine speed is greater than zero.
- System Voltage Low (Charge Fail) Message - Each time the cluster receives three consecutive
messages from the PCM or ECM indicating the electrical system voltage is less than about 9.0
volts (charge fail condition) or that the battery temperature sensor input is an open circuit, the
check gauges indicator will be illuminated and a single chime is sounded. The indicator remains
illuminated until the cluster receives a single message from the PCM or ECM indicating the
electrical system voltage is greater than about 9.5 volts (but less than about 15.5 volts), or until the
ignition switch is turned to the Off position, whichever occurs first.
- System Voltage High Message - Each time the cluster receives three consecutive messages from
the PCM or ECM indicating the electrical system voltage is greater than about 15.5 volts, the check
gauges indicator will be illuminated and a single chime is sounded. The indicator remains
illuminated until the cluster receives a single message from the PCM or ECM indicating the
electrical system voltage is less than about 15.0 volts (but greater than about 9.5 volts), or until the
ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the check gauges indicator
will be turned on, then off again during the bulb check portion of the test to confirm the functionality
of the LED and the cluster control circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the engine temperature, oil
pressure, and electrical system voltage, then sends the proper messages to the instrument cluster.
On vehicles with a diesel engine, the ECM continually monitors the engine temperature, oil
pressure, and electrical system voltage, then sends the proper messages to the instrument cluster.
For proper diagnosis of the PCM, the ECM, the PCI data bus, or the electronic message inputs to
the instrument cluster that control the check gauges indicator, a diagnostic scan tool is required.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component
Information > Diagrams > Diagram Information and Instructions > Page 7713
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component
Information > Diagrams > Diagram Information and Instructions > Page 7716
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Fig.7 Testing For Voltage Potential
STANDARD PROCEDURE - TESTING OF VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

2. Connect the other lead of the voltmeter to the other side of the switch, component or circuit. 3.
Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Description and Operation
Compass: Description and Operation
MODULE-COMPASS TEMPERATURE
The compass mini-trip computer is located in the overhead console (7) on models equipped with
this option. The compass mini-trip computer includes a Vacuum-Fluorescent Display (VFD) (6), an
Electronic Overhead Module (EOM) and push button function switches (1, 2, 4 and 5).
The compass mini-trip computer module contains a central processing unit and interfaces with
other electronic modules in the vehicle on the Programmable Communications Interface (PCI) data
bus. The PCI data bus allows the sharing of sensor information. This helps to reduce wire harness
complexity, reduce internal controller hardware, and reduce component sensor current loads. At
the same time, this system provides increased reliability, enhanced diagnostics, and allows the
addition of many new feature capabilities.
The compass mini-trip computer provides several electronic functions and features. Some of the
functions and features that the compass mini-trip computer supports and/or controls, include the
following display options:
- Compass and temperature - provides the outside temperature and one of eight compass readings
to indicate the direction the vehicle is facing.
- Trip odometer (TRIP ODO) - shows the distance travelled since the last trip computer reset.
- Average fuel economy (AVG ECO) - shows the average fuel economy since the last trip computer
reset.
- Distance to empty (DTE) - shows the estimated distance that can be travelled with the fuel
remaining in the fuel tank. This estimated distance is computed using the level of the fuel in the
tank and a weighted average of long term and recent Average Fuel Economy.
- Elapsed time (ET) - shows the accumulated ignition-on time since the last trip computer reset.
- Blank screen - the compass mini-trip VFD is turned off.
The ambient temperature sensor is hard wired to the Front Control Module (FCM). Data input for all
other compass mini-trip computer functions, including VFD dimming level, is received through PCI
data bus messages. The compass mini-trip computer uses its internal programming and all of
these inputs to calculate and display the requested data. If the data displayed is incorrect, perform
the self-diagnostic tests. If these tests prove inconclusive, the use of a scan tool and the proper
Diagnostic Procedures Information are recommended for further testing of the EOM and the PCI
data bus.
The EOM cannot be repaired, and is available for service only as a unit. This unit includes the push
button switches, the Universal Garage Door Transmitter and the plastic module and display lens. If
any of these components is inoperative or damaged, the complete EOM must be replaced.
COMPASS
While in the compass/temperature mode, the compass will display the direction in which the vehicle
is pointed using the eight major compass headings (Examples: north is N, northeast is NE). The
self-calibrating compass unit requires no adjusting in normal use. The only calibration that may
prove necessary is to drive the vehicle in one or two complete circles, on level ground, in not less
than 16 seconds. This will reorient the compass unit to its vehicle.
The compass unit also will compensate for magnetism the body of the vehicle may acquire during
normal use. However, avoid placing anything magnetic directly on the roof of the vehicle. Magnetic
mounts for an antenna, a repair order hat, or a funeral procession flag can exceed the
compensating ability of the compass unit if placed on the roof panel. Magnetic bit drivers used on
the fasteners that hold the overhead console assembly to the roof header can also affect compass
operation. If the vehicle roof should become magnetized.
TEMPERATURE
The temperature displays the outside ambient temperature in whole degrees. The temperature
display can be changed from Fahrenheit to Celsius using
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information >
Description and Operation > Page 7741
the U.S./Metric push button. The displayed temperature is not an instant reading of conditions, but
an average temperature. It may take the temperature display several minutes to respond to a major
temperature change, such as driving out of a heated garage into winter temperatures.
When the ignition switch is turned to the Off position, the last displayed temperature reading stays
in the temperature unit memory. When the ignition switch is turned to the On position again, the
temperature will display the memory temperature if the engine OFF time is less than 90 minutes. If
the engine OFF time is more than 90 minutes, the temperature will display the actual temperature
sensed by the ambient temperature sensor. The temperature display update interval varies with the
vehicle speed.
The temperature function is supported by an ambient temperature sensor. The sensor is mounted
outside the passenger compartment near the front and center of the vehicle, and is hard wired to
the FCM, which sends temperature over the PCI data bus circuit. The ambient temperature sensor
is available as a separate service item.
NOTE: The compass mini-trip computer will display min and max temperatures of -40° C (-40° F)
and 54° C (130° F).
The compass mini-trip computer only operates with the ignition switch in the On position. When the
ignition switch is turned to the On position, all of the segments in the compass mini-trip computer
Vacuum-Fluorescent Display (VFD) will be turned off for one second, then the display will return to
the last function being displayed before the ignition was turned to the Off position. With the ignition
switch in the On position, momentarily depressing and releasing the Step push button (4) will cause
the compass-mini-trip computer to change its mode of operation. Momentarily depressing and
releasing the U.S./Metric push button (1) will cause the unit to toggle between U.S. and Metric
measurements. Momentarily depressing and releasing the C/T (compass/temperature) push button
(5) will cause the compass mini-trip computer to return to the compass/temperature display mode
from any other mode.
This compass mini-trip computer features several functions that can be reset. If the RESET push
button (2) is depressed for more than one second with the ignition switch in the On position, the trip
computer information that can be reset is reset. However, the reset will only occur if the function
currently displayed is a function that can be reset. The functions that can be reset are: TRIP ODO,
AVG ECO, and ET. All three of these functions can be reset at once by pressing the RESET button
twice within 3 seconds while any one of the three functions is selected.

SELF- DIAGNOSTIC TEST. If the problem with the compass mini-trip computer is incorrect
Vacuum Fluorescent Display (VFD) dimming levels, use a scan tool and the proper Diagnostic
Procedures Information to test for the correct dimming message inputs being received from the
Body Control Module (BCM) or Front Control Module (FCM) over the Programmable
Communications Interface (PCI) data bus circuit. If the problem is a no-display condition, use the
following procedure.
For complete circuit diagrams, The wiring information includes wiring diagrams, proper wire and
connector repair procedures, details of wire harness routing and retention, connector pin-out
information and location views for the various wire harness connectors, splices and grounds.
1. Remove the overhead console from the headliner. 2. Check for battery voltage at the overhead
console electrical connector. If OK, go to Step 3. If not OK, Check for battery voltage at the
appropriate
B(+) fuse in the Integrated Power Module (IPM), repair the open fused B(+) circuit as required.
3. Turn the ignition switch to the On position. Check the fused ignition switch output circuit(s) at the
overhead console electrical connector. If OK,
go to Step 4. If not OK, repair the open or shorted circuit as required.
4. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable.
Check for continuity between the ground circuit
cavity of the overhead console electrical connector and a good ground. There should be continuity.
If OK, refer to SELF- DIAGNOSTIC TEST for further diagnosis of the Electronic Overhead Module
and the PCI data bus circuit. If not OK, repair the open ground circuit as required.
SELF- DIAGNOSTIC TEST
A self-diagnostic test is used to determine that the EOM is operating properly electrically. Initiate
the self-diagnostic test as follows:
NOTE: The compass mini-trip computer self - test can also be performed using a scan tool. Refer
to Auto Self Test under the System Tests.
1. With the ignition switch in the Off position, simultaneously depress and hold the STEP and
RESET buttons while rotating the ignition switch to
the Run/On position.
2. Continue to hold both buttons depressed until the EOM enters the display segment test. In this
test, all of the Vacuum Fluorescent Display (VFD)
segments are lighted while the EOM performs the following checks: Non-Volatile Memory Status (NVM)
- RAM Status
- ROM Status
- ASIC Communication Test Status
- Compass Test Status
- DC Status
- PCI data bus Communications Test
NOTE: If module is equipped with the Universal Transmitter, the module also checks "Universal
Transmitter Communication Test Status"
3. Following completion of these tests, the compass mini-trip computer will display one of two
messages: "FAIL" or "PASS." Press RESET or STEP
to exit and enter normal mode. Respond to these test results as follows: If no test result message is displayed, but compass mini-trip computer operation is still improper,
the use of a scan tool and the proper Diagnostic Procedures Information are required for further
diagnosis.
- If the "FAIL" message is displayed, the EOM is inoperative and must be replaced.
- If the "PASS" message is displayed, the EOM is OK, no faults are present.
- If any VFD segment does not light during the display segment test, the EOM is inoperative and
must be replaced.
4. If the first seven tests pass, the compass mini-trip computer shall verify that all the required PCI
bus messages are present on the PCI bus. If all
required messages are present on the PCI bus, or if the ignition switch is turned to the Off position,
the EOM will automatically return to normal operation. The required PCI bus messages are: Dimming message
- Fuel Used message
- Distance Pulses message
- Percentage Fuel Tank Full message
- Fuel Type message
- VIN (Vehicle Identification Number)
- Vehicle Speed message
- Last Engine Off Duration message
- Ambient Air Temperature message
NOTE:
- The Fuel Used message shall be ignored if the engine type is Diesel or Compressed Natural Gas.
- Pressing the STEP or RESET switches during any portion of the testing procedure will cause the

Compass: Adjustments
Compass variance, also known as magnetic declination, is the difference in angle between
magnetic north and true geographic north. In some geographic locations, the difference between
magnetic and geographic north is great enough to cause the compass to give false readings. If this
problem occurs, the compass variance must be set.
To set the compass variance:
1. Using the Variance Settings map, find your geographic location and note the zone number. 2.
Turn the ignition switch to the On/Run position. If the compass/temperature data is not currently
being displayed, momentarily depress and release
the C/T push button to step through the display options until you have reached the
compass/temperature display.
3. Press and hold the Reset push button down until "VAR" appears in the display. This takes about
five seconds. 4. Momentarily depress and release the STEP push button to step through the zone
numbers (1-15), until the zone number for your geographic
location appears in the display.
5. Momentarily depress and release the Reset push button to enter the displayed zone number into
the compass unit memory. 6. Confirm that the correct directions are now indicated by the compass.

Compass: Service and Repair Compass Calibration
CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the
vicinity of the compass. Do not use magnetic tools when servicing the overhead console.
The electronic compass unit features a self-calibrating design, which simplifies the calibration
procedure. This feature automatically updates the compass calibration while the vehicle is being
driven. This allows the compass unit to compensate for small changes in the residual magnetism
that the vehicle may acquire during normal use. If the compass readings appear to be erratic or out
of calibration, perform the following calibration procedure. Also, new service replacement compass
mini-trip computer modules must have their compass calibrated using this procedure. Do not
attempt to calibrate the compass near large metal objects such as other vehicles, large buildings,
or bridges; or, near overhead or underground power lines.
NOTE: Whenever the compass is calibrated manually, the variation number must also be reset.
Calibrate the compass manually as follows:
1. Turn the ignition switch to the On position. If the compass/temperature data is not currently being
displayed, momentarily depress and release the
C/T push button to step through the display options until you have reached the
compass/temperature display.
2. Depress and hold the RESET push button. Hold the push buttons down until "CAL" appears in
the display. This takes about ten seconds. 3. Drive the vehicle on a level surface, away from large
metal objects and power lines, through one or two complete circles in not less than 16
seconds. The "CAL" message will disappear from the display to indicate that the compass is now
calibrated.
NOTE:
- A blank compass display indicates that vehicle degaussing (demagnetizing) is necessary.
- If the "CAL" message remains in the display, either there is excessive magnetism near the
compass, or the unit is faulty. Repeat the calibration procedure at least one more time.
- If the wrong direction is still indicated in the compass display, the area selected for calibration
may be too close to a strong magnetic field. Repeat the calibration procedure in another location.

Compass: Service and Repair Compass Demagnetizing
Degaussing Tool #6029
A degaussing tool (Special Tool 6029) is used to demagnetize, or degauss, the overhead console
forward mounting screw and the roof panel above the overhead console. Equivalent units must be
rated as continuous duty for 110/115 volts and 60 Hz. They must also have a field strength of over
350 gauss at 7 millimeters (0.25 inch) beyond the tip of the probe.
To demagnetize the roof panel and the overhead console forward mounting screw, proceed as
follows:
1. Be certain that the ignition switch is in the Off position, before you begin the demagnetizing
procedure. 2. Connect the degaussing tool to an electrical outlet, while keeping the tool atleast 61
centimeters (2 feet) away from the compass unit. 3. Slowly approach the head of the overhead
console forward mounting screw with the degaussing tool connected. 4. Contact the head of the
screw with the plastic coated tip of the degaussing tool for about two seconds. 5. With the
degaussing tool still energized, slowly back it away from the screw. When the tip of the tool is
atleast 61 centimeters (2 feet) from the
screw head, disconnect the tool.
6. Place a piece of paper approximately 22 by 28 centimeters (8.5 by 11 inches), oriented on the
vehicle lengthwise from front to rear, on the center
line of the roof at the windshield header. The purpose of the paper is to protect the roof panel from
scratches, and to define the area to be demagnetized.
7. Connect the degaussing tool to an electrical outlet, while keeping the tool atleast 61 centimeters
(2 feet) away from the compass unit. 8. Slowly approach the center line of the roof panel at the
windshield header, with the degaussing tool connected. 9. Contact the roof panel with the plastic
coated tip of the degaussing tool. Be sure that the template is in place to avoid scratching the roof
panel.
Using a slow, back-and-forth sweeping motion, and allowing 13 millimeters (0.50 inch) between
passes, move the tool atleast 11 centimeters (4

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cruise Control Indicator Lamp >
Component Information > Description and Operation
Cruise Control Indicator Lamp: Description and Operation
A cruise indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional speed control system, this indicator is electronically disabled. The cruise
indicator consists of the word "CRUISE", which appears in the lower portion of the gear selector
indicator Vacuum-Fluorescent Display (VFD) unit.
The gear selector indicator VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the speedometer gauge
dial face of the cluster overlay. The dark lens over the VFD prevents the indicator from being
clearly visible when it is not illuminated. The "CRUISE" text appears in a blue-green color and at
the same lighting level as the gear selector indicator information when it is illuminated by the
instrument cluster electronic circuit board. The cruise indicator is serviced as a unit with the VFD in
the instrument cluster.
The cruise indicator gives an indication to the vehicle operator when the speed control system is
turned On, regardless of whether the speed control is engaged. This indicator is controlled by the
instrument cluster circuit board based upon cluster programming and electronic messages received
by the cluster from the Powertrain Control Module (PCM) over the Programmable Communications
Interface (PCI) data bus.
The cruise indicator is completely controlled by the instrument cluster logic circuit, and that logic
will only allow this indicator to operate when the instrument cluster receives a battery current input
on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
cruise indicator for the following reasons:
- Cruise Lamp-On Message - Each time the cluster receives a cruise lamp-on message from the
PCM indicating the speed control system has been turned On, the cruise indicator is illuminated.
The indicator remains illuminated until the cluster receives a cruise lamp-off message from the
PCM or until the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the cruise indicator will be
turned on, then off again during the VFD portion of the test to confirm the functionality of the VFD
and the cluster control circuitry.
The PCM continually monitors the speed control switches to determine the proper outputs to the
speed control servo. The PCM then sends the proper cruise indicator lamp-on and lamp-off
messages to the instrument cluster.
For proper diagnosis of the speed control system, the PCM, the PCI data bus, or the electronic
message inputs to the instrument cluster that control the cruise indicator, a diagnostic scan tool is
required.

Door/Trunk Ajar Indicator/Lamp: Description and Operation
A door ajar indicator is standard equipment on all instrument clusters. The door ajar indicator is
located on the right side of the instrument cluster, to the right of the engine temperature gauge.
The door ajar indicator consists of a stencil-like cutout of the words "DOOR AJAR" in the opaque
layer of the instrument cluster overlay. The dark outer layer of the overlay prevents the indicator
from being clearly visible when it is not illuminated. A red Light Emitting Diode (LED) behind the
cutout in the opaque layer of the overlay causes the "DOOR AJAR" text to appear in red through
the translucent outer layer of the overlay when the indicator is illuminated from behind by the LED,
which is soldered onto the instrument cluster electronic circuit board. The door ajar indicator is
serviced as a unit with the instrument cluster.
The door ajar indicator gives an indication to the vehicle operator that one or more of the
passenger compartment doors may be open or not completely latched. This indicator is controlled
by a transistor on the instrument cluster circuit board based upon cluster programming and hard
wired inputs received by the cluster from the door ajar switches located in each door latch unit.
The door ajar indicator Light Emitting Diode (LED) is completely controlled by the instrument
cluster logic circuit, and that logic will allow this indicator to operate whenever the instrument
cluster receives a battery current input on the fused ignition switch output (run-start) circuit.
Therefore, the LED will always be off when the ignition switch is in any position except On or Start.
The LED only illuminates when it is provided a path to ground by the instrument cluster transistor.
The instrument cluster will turn on the door ajar indicator for the following reasons:
- Door Ajar Switch Input - Each time the cluster detects ground on any one of the door ajar switch
sense circuits (door ajar switch closed = door is open or not completely latched) the door ajar
indicator will be illuminated. The indicator remains illuminated until all of the door ajar switch sense
inputs to the cluster are an open circuit (door ajar switch open = door fully closed), until the cluster
has completed an interior lamps load shed (about five minutes), or until the ignition switch is turned
to the Off position, whichever occurs first.
Actuator Test - Each time the cluster is put through the actuator test, the door ajar indicator will be
turned on, then off again during the bulb check portion of the test to confirm the functionality of the
LED and the cluster control circuitry.
The instrument cluster continually monitors the door ajar switches to determine the status of the
doors.

Description and Operation
Door Switch: Description and Operation
This vehicle has up to four door ajar switches, one for each door. Each switch is concealed within
and integral to its respective door latch unit. The switches are momentary leaf contact-type units
that are actuated by the mechanisms internal to the door latch. A short pigtail wire and connector
on each door latch connects the door ajar switch to the vehicle electrical system through its
respective door wire harness. The door ajar switches cannot be adjusted or repaired and, if faulty
or damaged, the door latch unit must be replaced.
The door ajar switches are actuated by the mechanisms internal to the door latch. When a door is
closed and properly latched, its door ajar switch is an open circuit. When a door is open or only
partially latched, the door ajar switch is a closed circuit. The door ajar switches are hard wired in
series between a body ground and the Electro-Mechanical Instrument Cluster (EMIC). The EMIC
reads the hard wired door ajar switch inputs through internal pull-ups, then uses these inputs to
control many electronic functions and features of the vehicle.
The EMIC also sends the proper switch status messages to other electronic modules over the
Programmable Communications Interface (PCI) data bus network. The door ajar switches can be
diagnosed and tested using conventional diagnostic tools and methods. However, conventional
diagnostic methods may not prove conclusive in the diagnosis of the EMIC, the PCI data bus, or
the electronic messaging used to convey door ajar switch status to other modules in the vehicle.
The most reliable, efficient, and accurate means to diagnose the EMIC, the PCI data bus, and both
the hard wired and electronic message inputs and outputs affected by the door ajar switch inputs
requires the use of a diagnostic scan tool.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Driver/Vehicle Information Display >
Component Information > Diagrams > Diagram Information and Instructions > Page 7773
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Component Information > Diagrams > Diagram Information and Instructions > Page 7776
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Driver/Vehicle Information Display: Description and Operation Overhead Console
An overhead console is available on this vehicle and includes the following components:
- Front map/reading lamps
- A blue-green vacuum-fluorescent display screen - if equipped with trip computer
- Universal transmitter - if equipped
- Electronic Overhead Module (EOM)
The overhead console assembly is mounted by two snap clips and screws securing it to a molded
plastic retainer bracket located above the headliner. The EOM is accessed by removing the
overhead console from the bracket and pulling it away from the headliner.
COMPASS DISPLAY
All the available overhead consoles on this model include Compass information. While in the
compass/temperature mode, the compass will display the direction in which the vehicle is pointed
using the eight major compass headings (Examples: north is N, northeast is NE). The
self-calibrating compass unit requires no adjusting in normal use. The only calibration that may
prove necessary is to drive the vehicle at 5 to 8 kilometers-per-hour (3 to 5 miles-per-hour), on
level ground in a square shaped pattern. This will reorient the compass unit to its vehicle.
The compass unit also will compensate for magnetism the body of the vehicle may acquire during
normal use. However, avoid placing anything magnetic directly on the roof of the vehicle. Magnetic
mounts for an antenna, a repair order hat, or a funeral procession flag can exceed the
compensating ability of the compass unit if placed on the roof panel. Magnetic bit drivers used on
the fasteners that hold the overhead console assembly to the roof header can also affect compass
operation. If the vehicle roof should become magnetized, the demagnetizing procedure may be
required to restore proper compass operation.
TEMPERATURE DISPLAY
All the available overhead consoles on this model include Temperature information. The
temperature displays the outside ambient temperature in whole degrees. The temperature display
can be toggled from Fahrenheit to Celsius by selecting the desired U.S./Metric option from the
customer programmable features. The displayed temperature is not an instant reading of
conditions, but an average temperature. It may take the temperature display several minutes to
respond to a major temperature change, such as driving out of a heated garage into winter
temperatures.
When the ignition switch is turned to the Off position, the last displayed temperature reading stays
in the electronic control modules, (CMTC, EVIC) memory. When the ignition switch is turned to the
On position again, the electronic module will display the memory temperature for one minute; then
update the display to the current average temperature reading within five minutes.
The temperature function is supported by an ambient temperature sensor. This sensor is mounted
outside the passenger compartment near the front and center of the vehicle, and is hard wired to
the Front Control Module (FCM). The FCM sends temperature status messages to the module over
the Programmable Communications Interface (PCI) data bus circuit. For more information on the
ambient temperature sensor.

Driver/Vehicle Information Display: Description and Operation Universal Transmitter
The universal transmitter transceiver is integral to the overhead console (7). The only visible
component of the universal transmitter are the three transmitter push buttons (3). The buttons are
marked with one, two or three dots, respectively, for identification of each channel.
Each of the three universal transmitter push buttons controls an independent radio transmitter
channel. Each of these three channels can be trained to transmit a different radio frequency signal
for the remote operation of garage door openers, motorized gate openers, home or office lighting,
security systems or just about any other device that can be equipped with a radio receiver in the
286 to 399 MegaHertz (MHz) frequency range for remote operation. The universal transmitter is
capable of operating systems using either rolling code or non-rolling code technology.
The universal transmitter cannot be repaired, and is available for service only as part of the
Electronic Overhead Module (EOM). This unit includes the push button switches for both the
transmitter and compass mini trip computer.
The universal transmitter operates on a non-switched source of battery current so the unit will
remain functional, regardless of the ignition switch position. It can learn and store three separate
transmitter radio frequency codes to operate garage door openers, security gates and security
lighting. The overhead console display provides visual feedback to the driver, showing which
transmitter button is pressed. The system will not send operating signals if the vehicle theft security
alarm is armed. This prevents a perpetrator from breaking into a vehicle parked outside a home
and using the transmitter system to enter the home.

If the problem with the overhead console is an inaccurate or scrambled display, refer to SELFDIAGNOSTIC TEST. If the problem with the overhead console is incorrect Vacuum Fluorescent
Display (VFD) dimming levels, use a scan tool and the proper Diagnostic Procedures Information to
test for the correct dimming message inputs being received from the Body Control Module (BCM)
or Front Control Module (FCM) over the Programmable Communications Interface (PCI) data bus
circuit. If the problem is a no-display condition, use the following procedure.
For complete circuit diagrams, The wiring information includes wiring diagrams, proper wire and
connector repair procedures, details of wire harness routing and retention, connector pin-out
information and location views for the various wire harness connectors, splices and grounds.
1. Remove the overhead console from the headliner. 2. Check for battery voltage at the overhead
console electrical connector. If OK, go to Step 3. If not OK, Check for battery voltage at the
appropriate
B(+) fuse in the Integrated Power Module (IPM), repair the open fused B(+) circuit as required.
3. Turn the ignition switch to the On position. Check the fused ignition switch output circuit(s) at the
overhead console electrical connector. If OK,
go to Step 4. If not OK, repair the open or shorted circuit as required.
4. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable.
Check for continuity between the ground circuit
cavity of the overhead console electrical connector and a good ground. There should be continuity.
If OK, refer to SELF- DIAGNOSTIC TEST for further diagnosis of the electronics module and the
PCI data bus circuit. If not OK, repair the open ground circuit as required.

Driver/Vehicle Information Display: Testing and Inspection Self-Diagnostic Test
A self-diagnostic test is used to determine that the EOM is operating properly electrically. Initiate
the self-diagnostic test as follows:
NOTE: The compass mini-trip computer self - test can also be performed using a scan tool. Refer
to Auto Self Test under the System Tests.
1. With the ignition switch in the Off position, simultaneously depress and hold the STEP and
RESET buttons while rotating the ignition switch to
the Run/On position.
2. Continue to hold both buttons depressed until the EOM enters the display segment test. In this
test, all of the Vacuum Fluorescent Display (VFD)
segments are lighted while the EOM performs the following checks: Non-Volatile Memory Status (NVM)
- RAM Status
- ROM Status
- ASIC Communication Test Status
- Compass Test Status
- DC Status
- PCI data bus Communications Test
NOTE: If module is equipped with the Universal Transmitter, the module also checks "Universal
Transmitter Communication Test Status"
3. Following completion of these tests, the compass mini-trip computer will display one of two
messages: "FAIL" or "PASS." Press RESET or STEP
to exit and enter normal mode. Respond to these test results as follows: If no test result message is displayed, but compass mini-trip computer operation is still improper,
the use of a scan tool and the proper Diagnostic Procedures Information are required for further
diagnosis.
- If the "FAIL" message is displayed, the EOM is inoperative and must be replaced.
- If the "PASS" message is displayed, the EOM is OK, no faults are present.
- If any VFD segment does not light during the display segment test, the EOM is inoperative and
must be replaced.
4. If the first seven tests pass, the compass mini-trip computer shall verify that all the required PCI
bus messages are present on the PCI bus. If all
required messages are present on the PCI bus, or if the ignition switch is turned to the Off position,
the EOM will automatically return to normal operation. The required PCI bus messages are: Dimming message
- Fuel Used message
- Distance Pulses message
- Percentage Fuel Tank Full message
- Fuel Type message
- VIN (Vehicle Identification Number)
- Vehicle Speed message
- Last Engine Off Duration message
- Ambient Air Temperature message
NOTE:
- The Fuel Used message shall be ignored if the engine type is Diesel or Compressed Natural Gas.
- Pressing the STEP or RESET switches during any portion of the testing procedure will cause the
compass mini-trip computer to exit diagnostics and return to compass/temperature mode.
- If the compass functions, but accuracy is suspect, it may be necessary to perform a variation
adjustment. This procedure allows the compass unit to accommodate variations in the earth's
magnetic field strength, based on geographic location.
- If the compass reading has blanked out, and only "CAL" appears in the display, demagnetizing
may be necessary to remove excessive residual magnetic fields from the vehicle.

Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Electronic Throttle Control Indicator >
Component Information > Description and Operation
Electronic Throttle Control Indicator: Description and Operation
An Electronic Throttle Control (ETC) indicator is standard equipment on all gasoline engine
instrument clusters. However, on vehicles not equipped with the I/I optional 5.7 liter gasoline
engine, this indicator is electronically disabled. The ETC indicator is located on the right side of the
instrument cluster, to the right of the engine temperature gauge.
The ETC indicator consists of a stencil-like cutout of the International Control and Display Symbol
icon for "Electronic Throttle Control" in the opaque layer of the instrument cluster overlay. The dark
outer layer of the overlay prevents the indicator from being clearly visible when it is not illuminated.
A red Light Emitting Diode (LED) behind the cutout in the opaque layer of the overlay causes the
icon to appear in red through the translucent outer layer of the overlay when the indicator is
illuminated from behind by the LED, which is soldered onto the instrument cluster electronic circuit
board. The ETC indicator is serviced as a unit with the instrument cluster.
The Electronic Throttle Control (ETC) indicator gives an indication to the vehicle operator when the
ETC system is faulty or inoperative. The ETC indicator is controlled by a transistor on the
instrument cluster circuit board based upon cluster programming and electronic messages received
by the cluster from the Powertrain Control Module (PCM) over the Programmable Communications
Interface (PCI) data bus.
The ETC indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster
logic circuit, and that logic will only allow this indicator to operate when the instrument cluster
receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the
LED will always be off when the ignition switch is in any position except On or Start. The LED only
illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument
cluster will turn on the ETC indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the ETC indicator is
illuminated for about six seconds. The entire six second bulb test is a function of the PCM.
- ETC Lamp-On Message - Each time the cluster receives a lamp-on message from the PCM, the
ETC indicator will be illuminated. The indicator can be flashed on and off, or illuminated solid, as
dictated by the PCM message. The indicator remains illuminated solid or continues to flash for
about twelve seconds or until the cluster receives a lamp-off message from the PCM, whichever is
longer. If the indicator is illuminated solid with the engine running the vehicle will usually remain
drivable. If the indicator is flashing with the engine running the vehicle may require towing. A
flashing indicator means the ETC system requires immediate service.
- Communication Error - If the cluster receives no ETC lamp messages for three consecutive
seconds, the ETC indicator is illuminated. The indicator remains illuminated until the cluster
receives a single lamp-off message from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the ETC indicator will be
turned on, then off again during the bulb check portion of the test to confirm the functionality of the
LED and the cluster control circuitry. The actuator test illumination of the ETC indicator is a function
of the PCM.
The PCM continually monitors the ETC system circuits and sensors to decide whether the system
is in good operating condition. The PCM then sends the proper lamp-on or lamp-off messages to
the instrument cluster. If the PCM sends a lamp-on message after the bulb test, it indicates that the
PCM has detected a system malfunction and/or that the ETC system is inoperative. The PCM will
store a Diagnostic Trouble Code (DTC) for any malfunction it detects. Each time the ETC indicator
fails to illuminate due to an open or short in the cluster ETC indicator circuit, the cluster sends a
message notifying the PCM of the condition, the instrument cluster and the PCM will each store a
DTC.
For proper diagnosis of the ETC system, the PCM, the PCI data bus, or the electronic message
inputs to the instrument cluster that control the ETC indicator, a diagnostic scan tool is required.

Component Information > Description and Operation
Four Wheel Drive Indicator Lamp: Description and Operation
A service 4WD indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional four-wheel drive system and electronically shifted transfer case, this
indicator is electronically disabled. The service 4WD indicator consists of the text "SERV 4WD",
which appears in the lower portion of the odometer/trip odometer Vacuum Fluorescent Display
(VFD) unit.
The odometer/trip odometer VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial
face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "SERV 4WD" appears in an amber color and at the same
lighting level as the odometer/trip odometer information when it is illuminated by the instrument
cluster electronic circuit board. The service 4WD indicator is serviced as a unit with the VFD in the
instrument cluster.
The service 4WD indicator gives an indication to the vehicle operator when the Transfer Case
Control Module (TCCM) has recorded a Diagnostic Trouble Code (DTC) for an electronic transfer
case circuit or component malfunction. This indicator is controlled by the instrument cluster circuit
board based upon cluster programming and electronic messages received by the cluster from the
TCCM over the Programmable Communications Interface (PCI) data bus.
The service 4WD indicator is completely controlled by the instrument cluster logic circuit, and that
logic will only allow this indicator to operate when the instrument cluster receives a battery current
input on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
service 4WD indicator for the following reasons:
- Service 4WD Lamp-On Message - Each time the cluster receives a service 4WD lamp-on
message from the TCCM, the indicator will be illuminated. The indicator remains illuminated until
the cluster receives a service 4WD lamp-off message from the TCCM, or until the ignition switch is
turned to the Off position, whichever occurs first.
- Communication Error - If the cluster receives no messages from the TCCM for five seconds, the
service 4WD indicator is illuminated by the instrument cluster to indicate a loss of TCCM
communication. The indicator remains controlled and illuminated by the cluster until a valid
message is received from the TCCM.
- Actuator Test - Each time the cluster is put through the actuator test, the service 4WD indicator
will be turned on, then off again during the VFD portion of the test to confirm the functionality of the
VFD and the cluster control circuitry.
The TCCM continually monitors the electronic transfer case switch and circuits to determine the
condition of the system. The TCCM then sends the proper lamp-on or lamp-off messages to the
instrument cluster.
For proper diagnosis of the TCCM, the PCI data bus, or the electronic message inputs to the
instrument cluster that control the service 4WD indicator, a diagnostic scan tool is required.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Fuel Gauge: Description and Operation
A fuel gauge is standard equipment on all instrument clusters. This gauge is located in the lower
left quadrant of the instrument cluster, below the voltage gauge. The fuel gauge consists of a
movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 90
degree scale on the cluster overlay that reads left-to-right from "E" (or Empty) to "F" (or Full).
An International Control and Display Symbol icon for "Fuel" is located on the cluster overlay,
directly below the right end of the gauge scale. An arrowhead pointed to the left side of the vehicle
is imprinted on the cluster overlay next to the "Fuel" icon in the fuel gauge to provide the driver with
a reminder as to the location of the fuel filler access. On vehicles equipped with a diesel engine,
text that specifies "DIESEL ONLY" is located across the fuel gauge below the gauge scale, but
above the hub of the gauge needle.
On all models except SRT-10 the fuel gauge graphics are black against a white field. On SRT-10
the gauge graphics are black against a silver field except for a single red graduation at the low end
of the gauge scale. In either case, the gauge graphics are clearly visible within the instrument
cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned On, the black gauge graphics appear blue-green and the red
graphics still appear red. The gauge needle has internal optical illumination. Gauge illumination is
provided by replaceable incandescent bulb and holder units located on the instrument cluster
electronic circuit board. The fuel gauge is serviced as a unit with the instrument cluster.
The fuel gauge gives an indication to the vehicle operator of the level of fuel in the fuel tank. This
gauge is controlled by the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) on vehicles
equipped with a gasoline engine, or from the Engine Control Module (ECM) on vehicles equipped
with a diesel engine over the Programmable Communications Interface (PCI) data bus.
The fuel gauge is an air core magnetic unit that receives battery current on the instrument cluster
electronic circuit board through the fused ignition switch output (run-start) circuit whenever the
ignition switch is in the On or Start positions. The cluster is programmed to move the gauge needle
back to the low end of the scale after the ignition switch is turned to the Off position. The instrument
cluster circuitry controls the gauge needle position and provides the following features:
- Percent Tank Full Message - Each time the cluster receives a message from the PCM or ECM
indicating the percent tank full, the cluster programming applies an algorithm to calculate the
proper gauge needle position, then moves the gauge needle to the proper relative position on the
gauge scale. The algorithm is used to dampen gauge needle movement against the negative effect
that fuel sloshing within the fuel tank can have on accurate inputs from the fuel tank sending unit to
the PCM or ECM.
- Less Than Fifteen Percent Tank Full Message - Each time the cluster receives messages from
the PCM or ECM indicating the percent tank full is about fifteen percent or less for ten consecutive
seconds and the vehicle speed is zero, or for sixty consecutive seconds and the vehicle speed is
greater than zero, the gauge needle is moved to between the one-sixteenth and one-eighth
graduations or below on the gauge scale, the low fuel indicator is illuminated, and a single chime
tone is sounded. The low fuel indicator remains illuminated until the cluster receives messages
from the PCM or ECM indicating that the percent tank full is greater than about fifteen percent for
ten consecutive seconds and the vehicle speed is zero, or for sixty consecutive seconds and the
vehicle speed is greater than zero, or until the ignition switch is turned to the Off position,
whichever occurs first. The chime tone feature will only repeat during the same ignition cycle if the
low fuel indicator is cycled off and then on again by the appropriate percent tank full messages
from the PCM or ECM.
- Less Than Empty Percent Tank Full Message - Each time the cluster receives a message from
the PCM or ECM indicating the percent tank full is less than empty, the gauge needle is moved to
the far left end of the gauge scale and the low fuel indicator is illuminated immediately. This
message would indicate that the fuel tank sender input to the PCM or ECM is a short circuit.
- more than Full Percent Tank Full Message - Each time the cluster receives a message from the
PCM or ECM indicating the percent tank full is more than full, the gauge needle is moved to the far
left end of the gauge scale and the low fuel indicator is illuminated immediately. This message
would indicate that the fuel tank sender input to the PCM or ECM is an open circuit.
- Communication Error - If the cluster fails to receive a percent tank full message, it will hold the
gauge needle at the last indication for about ten seconds, or until the ignition switch is turned to the
Off position, whichever occurs first. After ten seconds, the cluster will move the gauge needle to the
low end of the gauge scale.
- Actuator Test - Each time the cluster is put through the actuator test, the fuel gauge needle will be
swept to several calibration points on the gauge scale in a prescribed sequence in order to confirm
the functionality of the gauge and the cluster control circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the fuel tank sending unit to
determine the level of the fuel in the fuel tank. On vehicles with a diesel engine, the ECM
continually monitors the fuel tank sending unit to determine the level of the fuel in the fuel tank. The
PCM or ECM then sends the proper fuel level messages to the instrument cluster. For further
diagnosis of the fuel gauge or the instrument cluster circuitry that controls the gauge, refer to
testing.
For proper diagnosis of the fuel tank sending unit, the PCM, the ECM, the PCI data bus, or the
electronic message inputs to the instrument cluster that

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge Sender > Component
Information > Diagrams > Diagram Information and Instructions > Page 7832
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge Sender > Component
Information > Diagrams > Page 7852
Fuel Gauge Sender: Description and Operation
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant current source is supplied to the resistor track on the fuel
gauge sending unit. This is fed directly from the Powertrain Control Module (PCM).
NOTE: For diagnostic purposes, this 12V power source can only be verified with the circuit opened
(fuel pump module electrical connector unplugged). With the connectors plugged, output voltages
will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about 8.6 volts at EMPTY for
Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The resistor track is used to
vary the voltage (resistance) depending on fuel tank float level. As fuel level increases, the float
and arm move up, which decreases voltage. As fuel level decreases, the float and arm move down,
which increases voltage. The varied voltage signal is returned back to the PCM through the sensor
return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/ setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Lamp Out Indicator > Component
Information > Description and Operation
Lamp Out Indicator: Description and Operation
A lamp out indicator is standard equipment on all instrument clusters. The lamp out indicator
consists of the words "LAMP OUT", which appear in the lower portion of the odometer/trip
odometer Vacuum-Fluorescent Display (VFD) unit.
The odometer/trip odometer VFD unit is soldered onto the cluster electronic circuit board and is
visible through a window with a smoked clear lens located on the lower edge of the tachometer
gauge dial face of the cluster overlay. The dark lens over the VFD prevents the lamp out indicator
from being clearly visible when it is not illuminated. The words "LAMP OUT" appear in an amber
color and at the same lighting level as the odometer/trip odometer information when they are
illuminated by the instrument cluster electronic circuit board. The lamp out indicator is serviced as a
unit with the VFD in the instrument cluster.
The lamp out indicator gives an indication to the vehicle operator when an exterior lamp has failed.
This indicator is controlled by the instrument cluster circuit board based upon cluster programming
and electronic messages received by the cluster from the Front Control Module (FCM) over the
Programmable Communications Interface (PCI) data bus.
The lamp out indicator is completely controlled by the instrument cluster logic circuit, and that logic
will only allow this indicator to operate when the instrument cluster receives a battery current input
on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the lamp
out indicator for the following reasons:
- Lamp Out Indicator Lamp-On Message - Each time the cluster receives a lamp out indicator
lamp-on message from the FCM indicating that an inoperative headlamp (low or high beam), turn
signal lamp, or brake lamp (excluding Center High Mounted Stop Lamp [CHMSL]) circuit has been
detected with the ignition switch in the On position, the lamp out indicator is illuminated solid. The
indicator remains illuminated until the cluster receives a lamp out indicator lamp-off message from
the FCM or until the ignition switch is turned to the Off position, whichever occurs first. If the
lamp-on message is received when the ignition is first turned to the On position, the lamp out
indicator is flashed at a fast rate (1 Hertz) for about thirty seconds before illuminating solid.
- Actuator Test - Each time the cluster is put through the actuator test, the lamp out indicator will be
turned on, then off again during the VFD portion of the test to confirm the functionality of the VFD
and the cluster control circuitry.
The FCM monitors each of the headlamp, turn signal lamp, and brake lamp (except CHMSL)
circuits to determine the condition of these exterior lamps. The FCM then sends the proper lamp
out indicator lamp-on and lamp-off messages to the instrument cluster. For further diagnosis of the
lamp out indicator or the instrument cluster circuitry that controls the indicator, refer to testing.
For proper diagnosis of the exterior lighting system circuits, the FCM, the PCI data bus, or the
electronic message inputs to the instrument cluster that control the lamp out indicator, a diagnostic
scan tool is required.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Low Fuel Lamp/Indicator > Component
Information > Description and Operation
Low Fuel Lamp/Indicator: Description and Operation
A low fuel indicator is standard equipment on all instrument clusters. This indicator is located on the
left side of the instrument cluster, to the left of the fuel gauge.
The low fuel indicator consists of a stencil-like cutout of the International Control and Display
Symbol icon for "Fuel" in the opaque layer of the instrument cluster overlay. The dark outer layer of
the overlay prevents the indicator from being clearly visible when it is not illuminated. An amber
Light Emitting Diode (LED) behind the cutout in the opaque layer of the overlay causes the icon to
appear in amber through the translucent outer layer of the overlay when the indicator is illuminated
from behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The
low fuel indicator is serviced as a unit with the instrument cluster.
The low fuel indicator gives an indication to the vehicle operator when the level of fuel in the fuel
tank becomes low. This indicator is controlled by a transistor on the instrument cluster circuit board
based upon cluster programming and electronic messages received by the cluster from the
Powertrain Control Module (PCM) on vehicles equipped with a gasoline engine, or from the Engine
Control Module (ECM) on vehicles equipped with a diesel engine over the Programmable
Communications Interface (PCI) data bus.
The low fuel indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster
logic circuit, and that logic will only allow this indicator to operate when the instrument cluster
receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the
LED will always be off when the ignition switch is in any position except On or Start. The LED only
illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument
cluster will turn on the low fuel indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the low fuel indicator is
illuminated for about two seconds as a bulb test.
- Less Than Fifteen Percent Tank Full Message - Each time the cluster receives messages from
the PCM or ECM indicating the percent tank full is about fifteen percent or less for ten consecutive
seconds and the vehicle speed is zero, or for sixty consecutive seconds and the vehicle speed is
greater than zero, the fuel gauge needle is moved to between the one-sixteenth and one-eighth
graduations or below on the gauge scale, the low fuel indicator is illuminated and a single chime
tone is sounded. The low fuel indicator remains illuminated until the cluster receives messages
from the PCM or ECM indicating that the percent tank full is greater than about fifteen percent for
ten consecutive seconds and the vehicle speed is zero, or for sixty consecutive seconds and the
vehicle speed is greater than zero, or until the ignition switch is turned to the Off position,
whichever occurs first. The chime tone feature will only repeat during the same ignition cycle if the
low fuel indicator is cycled off and then on again by the appropriate percent tank full messages
from the PCM or ECM.
- Less Than Empty Percent Tank Full Message - Each time the cluster receives a message from
the PCM or ECM indicating the percent tank full is less than empty, the low fuel indicator is
illuminated immediately. This message would indicate that the fuel tank sender input to the PCM or
ECM is a short circuit.
- More Than Full Percent Tank Full Message - Each time the cluster receives a message from the
PCM or ECM indicating the percent tank full is more than full, the low fuel indicator is illuminated
immediately. This message would indicate that the fuel tank sender input to the PCM or ECM is an
open circuit.
- Actuator Test - Each time the cluster is put through the actuator test, the low fuel indicator will be
turned on, then off again during the bulb check portion of the test to confirm the functionality of the
LED and the cluster control circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the fuel tank sending unit to
determine the level of fuel in the fuel tank. On vehicles with a diesel engine, the ECM continually
monitors the fuel tank sending unit to determine the level of fuel in the fuel tank. The PCM or ECM
then sends the proper fuel level messages to the instrument cluster. For further diagnosis of the
low fuel indicator or the instrument cluster circuitry that controls the LED, refer to testing.
For proper diagnosis of the fuel tank sending unit, the PCM, the ECM, the PCI data bus, or the
electronic message inputs to the instrument cluster that control the low fuel indicator, a diagnostic
scan tool is required.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Malfunction Indicator Lamp > Component
Information > Description and Operation
Malfunction Indicator Lamp: Description and Operation
A Malfunction Indicator Lamp (MIL) is standard equipment on all instrument clusters. This indicator
is located on the left side of the instrument cluster, to the left of the voltage gauge.
The MIL consists of a stencil-like cutout of the International Control and Display Symbol icon for
"Engine" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. An amber Light Emitting
Diode (LED) behind the cutout in the opaque layer of the overlay causes the icon to appear in
amber through the translucent outer layer of the overlay when the indicator is illuminated from
behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The MIL
is serviced as a unit with the instrument cluster.
The Malfunction Indicator Lamp (MIL) gives an indication to the vehicle operator when the
Powertrain Control Module (PCM) on vehicles with a gasoline engine, or the Engine Control
Module (ECM) on vehicles with a diesel engine has recorded a Diagnostic Trouble Code (DTC) for
an On-Board Diagnostics II (OBDII) emissions-related circuit or component malfunction. The MIL is
controlled by a transistor on the instrument cluster circuit board based upon cluster programming
and electronic messages received by the cluster from the PCM or ECM over the Programmable
Communications Interface (PCI) data bus.
The MIL Light Emitting Diode (LED) is completely controlled by the instrument cluster logic circuit,
and that logic will only allow this indicator to operate when the instrument cluster receives a battery
current input on the fused ignition switch output (run-start) circuit. Therefore, the LED will always be
off when the ignition switch is in any position except On or Start. The LED only illuminates when it
is provided a path to ground by the instrument cluster transistor. The instrument cluster will turn on
the MIL for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the indicator is illuminated for
about two seconds as a bulb test. The entire bulb test is a function of the PCM or ECM.
- MIL Lamp-On Message - Each time the cluster receives a MIL lamp-on message from the PCM or
ECM, the indicator will be illuminated. The indicator can be flashed on and off, or illuminated solid,
as dictated by the PCM or ECM message. For some DTC's, if a problem does not recur, the PCM
or ECM will send a lamp-off message automatically. Other DTC's may require that a fault be
repaired and the PCM or ECM be reset before a lamp-off message will be sent.
- Communication Error - If the cluster receives no messages from the PCM or ECM for about ten
seconds, the MIL is illuminated by the instrument cluster to indicate a loss of bus communication.
The indicator remains controlled and illuminated by the cluster until a valid message is received
from the PCM or ECM.
- Actuator Test - Each time the cluster is put through the actuator test, the MIL indicator will be
turned on during the bulb check portion of the test to confirm the functionality of the LED and the
cluster control circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the fuel and emissions system
circuits and sensors to decide whether the system is in good operating condition. On vehicles with
a diesel engine, the ECM continually monitors the fuel and emissions system circuits and sensors
to decide whether the system is in good operating condition. The PCM or ECM then sends the
proper lamp-on or lamp-off messages to the instrument cluster. For further diagnosis of the MIL or
the instrument cluster circuitry that controls the LED, refer to testing. If the instrument cluster turns
on the MIL after the bulb test, it may indicate that a malfunction has occurred and that the fuel and
emissions systems may require service.
For proper diagnosis of the fuel and emissions systems, the PCM, the ECM, the PCI data bus, or
the electronic message inputs to the instrument cluster that control the MIL, a diagnostic scan tool
is required.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Odometer > Component Information >
Description and Operation
Odometer: Description and Operation
An odometer and trip odometer are standard equipment in all instrument clusters. The odometer,
trip odometer, and engine hours information are displayed BBBSB.S"" in a common electronic,
blue-green Vacuum-Fluorescent Display (VFD) unit. This VFD unit is soldered onto the cluster
electronic circuit board and is visible through a window with a smoked lens located on the lower
edge of the tachometer gauge dial face of the cluster overlay. The dark lens over the VFD prevents
it from being clearly visible when it is not illuminated.
The odometer, trip odometer, and engine hours information are not displayed simultaneously. The
trip odometer reset switch on the instrument cluster circuit board toggles the display between
odometer and trip odometer modes by depressing the odometer/trip odometer switch button that
extends through the lower edge of the cluster lens, just left of the odometer VFD. When the trip
odometer information is displayed, the word "TRIP" is also illuminated in the upper right corner of
the VFD in a blue-green color and at the same lighting level as the trip odometer information. On all
models except SRT-10, the engine hours information replaces the selected odometer or trip
odometer information whenever the ignition switch is in the On position and the engine is not
running. The engine hours feature is disabled on all SRT-10 models.
The odometer, trip odometer, and engine hours information is stored in the instrument cluster
memory. This information can be increased when the proper inputs are provided to the instrument
cluster, but the information cannot be decreased. The odometer can display values up to 999,999
kilometers (999,999 miles). The odometer latches at these values, and will not roll over to zero.
The trip odometer can display values up to 9,999.9 kilometers (9,999.9 miles) before it rolls over to
zero. Engine hours are displayed in the format, "hr9999". The cluster will accumulate values up to
9,999 hours before the display rolls over to zero.
The odometer display does not have a decimal point and will not show values less than a full unit
(kilometer or mile), while the trip odometer display does have a decimal point and will show tenths
of a unit (kilometer or mile). The unit of measure (kilometers or miles) for the odometer and trip
odometer display is not shown in the VFD. The unit of measure for the instrument cluster
odometer/trip odometer is selected at the time that it is manufactured, and cannot be changed. The
odometer also has a "Rental Car" mode, which will illuminate the odometer information in the VFD
whenever the driver side front door is opened with the ignition switch in the Off or Accessory
positions.
During daylight hours (exterior lamps are Off) the odometer VFD is illuminated at full brightness for
clear visibility. At night (exterior lamps are On), the VFD lighting level is adjusted with the other
cluster illumination lamps using the panel lamps dimmer thumbwheel on the headlamp switch.
However, a "Parade" mode position of the panel lamps dimmer thumbwheel allows the VFD to be
illuminated at full brightness if the exterior lamps are turned On during daylight hours.
The odometer/trip odometer VFD, the trip odometer switch, and the trip odometer switch button are
serviced as a unit with the instrument cluster.
The odometer and trip odometer give an indication to the vehicle operator of the distance the
vehicle has traveled. On all models except SRT-10, the engine hours give an indication of the
cumulative engine-on time. The engine hours feature is disabled on SRT-10 models. This indicator
is controlled by the instrument cluster circuitry based upon cluster programming and electronic
messages received by the cluster from the Powertrain Control Module (PCM) or Engine Control
Module (ECM) over the Programmable Communications Interface (PCI) data bus.
The odometer, trip odometer and engine hours information is displayed by the instrument cluster
odometer Vacuum Fluorescent Display (VFD). The odometer VFD will display the odometer
information whenever the driver side front door is opened with the ignition switch in the Off or
Accessory positions, and will display the last previously selected odometer or trip odometer
information when the ignition switch is turned to the On or Start positions. The instrument cluster
circuitry controls the VFD and provides the following features:
- Odometer/Trip Odometer Display Toggling - Actuating the trip odometer reset switch button
momentarily with the VFD illuminated will toggle the display between the odometer and trip
odometer information. Each time the VFD is illuminated with the ignition switch in the On or Start
positions, the display will automatically return to the last mode previously selected (odometer or trip
odometer).
- Engine Hours Display Toggling - When the trip odometer reset switch button is pressed and held
for longer than about six seconds with the ignition switch in the On position and the engine speed
message from the PCM is zero, the trip odometer information will be momentarily displayed, then
the engine hours information will be displayed. The VFD must be displaying the odometer
information when the trip odometer reset switch button is pressed in order to toggle to the engine
hours display. The engine hours will remain displayed for about thirty seconds, until the engine
speed message is greater than zero, or until the ignition switch is turned to the Off position,
whichever occurs first.
- Trip Odometer Reset - When the trip odometer reset switch button is pressed and held for longer
than about two seconds with the ignition switch in the On or Start position, the trip odometer will be
reset to 0.0 kilometers (miles). The VFD must be displaying the trip odometer information in order
for the trip odometer information to be reset.
- Communication Error - If the cluster fails to receive a distance message during normal operation,
it will hold and display the last data received until the ignition switch is turned to the Off position. If
the cluster does not receive a distance message within one second after the ignition switch is
turned to the On position, it will display the last distance message stored in the cluster memory. If
the cluster is unable to display distance information due to an error internal to the cluster, the VFD
will display all dashes.
- Actuator Test - Each time the cluster is put through the actuator test, the odometer VFD will
display all of its segments simultaneously during the VFD portion of the test to confirm the
functionality of each of the VFD segments and the cluster control circuitry.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Gauge > Component
Information > Description and Operation
Oil Pressure Gauge: Description and Operation
An oil pressure gauge is standard equipment on all instrument clusters. The oil pressure gauge is
located in the upper right quadrant of the instrument cluster, above the coolant temperature gauge.
The oil pressure gauge consists of a movable gauge needle or pointer controlled by the instrument
cluster circuitry and a fixed 90 degree scale on the cluster overlay that reads left-to-right from "L"
(or Low) to "H" (or High) for gasoline engines except SRT-10. On SRT-10 models, the scale reads
from "0" kPa to "700" kPa in markets where a metric instrument cluster is specified, or from "0" psi
to "100" psi in all other markets. On vehicles with a diesel engine the scale reads from "0" kPa to
"760" kPa in markets where a metric instrument cluster is specified, or from "0" psi to "110" psi in
all other markets.
An International Control and Display Symbol icon for "Engine Oil" is located on the cluster overlay,
directly below the left end of the gauge scale. On all models except SRT-10 the oil pressure gauge
graphics are black against a white field except for two red graduations at the low end of the gauge
scale. On SRT-10 the gauge graphics are black against a silver field except for a single red zone at
the low end of the gauge scale. In either case, the gauge graphics are clearly visible within the
instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned On, the black graphics appear blue-green and the red graphics still
appear red. The gauge needle has internal optical illumination. Gauge illumination is provided by
replaceable incandescent bulb and holder units located on the instrument cluster electronic circuit
board. The oil pressure gauge is serviced as a unit with the instrument cluster.
The oil pressure gauge gives an indication to the vehicle operator of the engine oil pressure. This
gauge is controlled by the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) on vehicles
with a gasoline engine, or from the Engine Control Module (ECM) on vehicles equipped with a
diesel engine over the Programmable Communications Interface (PCI) data bus.
The oil pressure gauge is an air core magnetic unit that receives battery current on the instrument
cluster electronic circuit board through the fused ignition switch output (run-start) circuit whenever
the ignition switch is in the On or Start positions. The cluster is programmed to move the gauge
needle back to the low end of the scale after the ignition switch is turned to the Off position. The
instrument cluster circuitry controls the gauge needle position and provides the following features:
- Engine Oil Pressure Message - The instrument cluster circuitry restricts the oil pressure gauge
needle operation in order to provide readings that are consistent with customer expectations. For
all models except SRT-10, each time the cluster receives a message from the PCM or ECM
indicating the engine oil pressure is above about 41 kPa (6 psi) the cluster holds the gauge needle
at a point near the middle increment within the normal range on the gauge scale. For SRT-10
models, each time the cluster receives a message from the PCM indicating the engine oil pressure
is above about 41 kPa (6 psi) the cluster moves the gauge needle in a linear fashion to the proper
relative pressure position of the gauge scale.
- Engine Oil Pressure Low Message - Each time the cluster receives three consecutive bus
messages from the PCM or ECM indicating the engine oil pressure is below about 41 kPa (6 psi),
the gauge needle is moved to the red graduations (except SRT-10) or to the red zone (SRT-10) at
the far left end of the gauge scale, the check gauges indicator is illuminated, and a single chime
tone is generated. The gauge needle remains at the left end of the gauge scale and the check
gauges indicator remains illuminated until the cluster receives a message from the PCM or ECM
indicating that the engine oil pressure is above about 41 kPa (6 psi), or until the ignition switch is
turned to the Off position, whichever occurs first. The cluster will only turn the check gauges
indicator on in response to an engine oil pressure low message if the engine speed message is
greater than zero.
- Communication Error - If the cluster fails to receive an engine oil pressure message, it will hold
the gauge needle at the last indication for about ten seconds, or until the ignition switch is turned to
the Off position, whichever occurs first. After ten seconds, the cluster will move the gauge needle to
the low end of the gauge scale.
- Actuator Test - Each time the cluster is put through the actuator test, the oil pressure gauge
needle will be swept to several calibration points on the gauge scale in a prescribed sequence in
order to confirm the functionality of the gauge and the cluster control circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the engine oil pressure sensor to
determine the engine oil pressure. On vehicles with a diesel engine, the ECM continually monitors
the engine oil pressure sensor to determine the engine oil pressure. The PCM or ECM then sends
the proper engine oil pressure messages to the instrument cluster. If the instrument cluster turns on
the check gauges indicator due to a low oil pressure gauge reading, it may indicate that the engine
or the engine oiling system requires service.
For proper diagnosis of the engine oil pressure sensor, the PCM, the ECM, the PCI data bus, or
the electronic message inputs to the instrument cluster that control the oil pressure gauge, a
diagnostic scan tool is required.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Sender > Component
Information > Diagrams > Diagram Information and Instructions > Page 7882
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Temperature Gauge > Component
Information > Description and Operation
Oil Temperature Gauge: Description and Operation
An oil temperature gauge (1) is standard equipment on all SRT-10 models. This electronic, analog
gauge is located in the lower end of the left A-pillar trim molding below the grab handle (2), in clear
view of the vehicle operator. The gauge dial face is visible through a clear plastic lens, which is
secured to the gauge housing with a silver anodized trim ring. The remainder of the gauge,
including the mounting provisions and the electrical connections, are concealed behind the left
A-pillar trim molding.
The molded plastic housing at the rear of the gauge protects the electronic circuitry of the gauge
and has two mounting studs, which are secured by nuts to a molded plastic mounting bracket
screwed to the back of the A-pillar trim molding. A short pigtail wire with a connector extends from
the back of the gauge housing and connects the gauge to the vehicle electrical system through a
take out and connector of the instrument panel wire harness.
The oil temperature gauge consists of a movable gauge needle or pointer with a 270 degree sweep
that is controlled by the electronic gauge circuitry. The gauge overlay reads left-to-right from "60" to
"150" with "° C" indicated directly below the low (left) end of the scale in markets where a metric
instrument cluster is specified, or from "140" to "300" with "° F" indicated directly below the left end
of the scale for all other markets. The text "OIL TEMP" is imprinted on the center of the gauge
overlay below the hub of the gauge needle, while the text "SRT" is imprinted above the hub of the
gauge needle. The gauge graphics are black against a silver field except for a single red zone at
the high (right) end of the gauge scale and are clearly visible in daylight.
General illumination lighting for the gauge is provided by a Light Emitting Diode (LED) that is
soldered onto the gauge circuit board. The gauge overlay is a laminated plastic unit. The dark,
visible, outer surface of the overlay is marked with the gauge dial face and graduations, but this
layer is also translucent. The underlying layer of the overlay is opaque and allows light from the
LED on the circuit board behind it to be visible through the outer layer of the overlay only through
predetermined stencil-like cutouts. When illuminated from behind by the panel lamps dimmer
controlled gauge lighting with the exterior lamps turned On, the black graphics appear blue-green
and the red graphics still appear red. The gauge needle has internal optical illumination.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Temperature Gauge > Component
Information > Description and Operation > Page 7906
The oil temperature gauge cannot be repaired or adjusted and, if damaged or faulty, it must be
replaced. The gauge illumination LED unit is not available for service replacement and, if damaged
or faulty, the entire gauge must be replaced.
The oil temperature gauge gives an indication to the vehicle operator of the engine oil temperature.
This gauge is controlled by its own internal electronic circuit board based upon a hard wired input
received by the gauge from an oil temperature sensor (4) installed in a tapped hole that penetrates
an oil passage on the right side of the engine block (2) just behind the oil pressure sensor (3).
The oil temperature sensor is a Negative Temperature Coefficient (NTC) thermistor that changes
its internal resistance with changes in temperature. The sensor has two terminals. One terminal
receives a hard wired ground path through a take out and connector of the engine wire harness (1),
and the second terminal provides a variable output to the gauge through the same take out and
connector. As the oil temperature increases the resistance of the sensor decreases, and as the oil
temperature decreases the resistance of the sensor increases.
The oil temperature gauge is an air core magnetic unit. The gauge pigtail wire and connector
provides the gauge electronic circuit board with a hard wired ground path, battery current through a
fused ignition switch output (run-start) circuit, a Pulse Width Modulated (PWM) panel lamps dimmer
input from the instrument cluster for general illumination, and the input from the oil temperature
sensor. This gauge is only operational when the ignition switch is in the On or Start positions. The
gauge electronic circuit board reads the input from the oil temperature sensor, then provides linear
positioning of the gauge needle on the gauge scale based upon that input. The gauge electronics
will move the gauge needle back to the low end of the scale after the ignition switch is turned to the
Off position.
The oil temperature gauge and the oil temperature sensor may be diagnosed using conventional
diagnostic tools and methods.

Oil Temperature Gauge: Testing and Inspection
WARNING: TO AVOID PERSONAL INJURY OR DEATH, ON VEHICLES EQUIPPED WITH
AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY
STEERING WHEEL, STEERING COLUMN, AIRBAG, SEAT BELT TENSIONER, IMPACT
SENSOR, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT
AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR
THE SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS
OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE SUPPLEMENTAL RESTRAINT
SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT.
The hard wired oil temperature gauge and gauge lighting circuits may be diagnosed and tested
using conventional diagnostic tools and procedures. The wiring information includes wiring
diagrams, proper wire and connector repair procedures, details of wire harness routing and
retention, connector pin-out information and location views for the various wire harness connectors,
splices and grounds.
NOTE: When testing the oil temperature gauge by alternately opening and shorting the oil
temperature sensor signal circuit, the gauge pointer may rotate in either direction (clockwise or
counterclockwise) to reach the objective point on the gauge scale. This is a normal condition as the

Overdrive Indicator Lamp: Description and Operation
A tow/haul indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional overdrive automatic transmission, this indicator is electronically
disabled. The tow/haul indicator consists of the text "TOW/HAUL", which appears in the lower
portion of the odometer/trip odometer indicator Vacuum Fluorescent Display (VFD) unit.
The odometer/trip odometer VFD is soldered onto the cluster electronic circuit board and is visible
through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial
face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "TOW/ HAUL" appears in an amber color and at the
same lighting level as the odometer/trip odometer information when it is illuminated by the
instrument cluster electronic circuit board. The tow/haul indicator is serviced as a unit with the VFD
in the instrument cluster.
The tow/haul indicator gives an indication to the vehicle operator when the Off position of the
tow/haul switch has been selected, disabling the electronically controlled overdrive feature of the
automatic transmission. This indicator is controlled by the instrument cluster circuit board based
upon cluster programming and electronic messages received by the cluster from the Powertrain
Control Module (PCM) over the Programmable Communications Interface (PCI) data bus.
The tow/haul indicator is completely controlled by the instrument cluster logic circuit, and that logic
will only allow this indicator to operate when the instrument cluster receives a battery current input
on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
tow/haul indicator for the following reasons:
- Tow/Haul Lamp-On Message - Each time the cluster receives a tow/haul lamp-on message from
the PCM indicating that the Off position of the tow/haul switch has been selected, the tow/haul
indicator will be illuminated. The indicator remains illuminated until the cluster receives a tow/haul
lamp-off message from the PCM, or until the ignition switch is turned to the Off position, whichever
occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the tow/haul indicator will be
turned on, then off again during the VFD portion of the test to confirm the functionality of the VFD
and the cluster control circuitry.
The PCM continually monitors the tow/haul switch to determine the proper outputs to the automatic
transmission. The PCM then sends the proper tow/haul lamp-on and lamp-off messages to the
instrument cluster.
For proper diagnosis of the overdrive control system, the PCM, the PCI data bus, or the electronic
message inputs to the instrument cluster that control the tow/haul indicator, a diagnostic scan tool
is required.

Parking Brake Warning Lamp: Description and Operation
A brake indicator is standard equipment on all instrument clusters. This indicator is located near the
lower edge of the instrument cluster, between the tachometer and the speedometer.
The brake indicator consists of a stencil-like cutout of the word "BRAKE" and the International
Control and Display Symbol icon for "Brake Failure" in the opaque layer of the instrument cluster
overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it
is not illuminated. A red Light Emitting Diode (LED) behind the cutout in the opaque layer of the
overlay causes the "BRAKE" text and icon to appear in red through the translucent outer layer of
the overlay when the indicator is illuminated from behind by the LED, which is soldered onto the
instrument cluster electronic circuit board. The brake indicator is serviced as a unit with the
instrument cluster.
The brake indicator gives an indication to the vehicle operator when the parking brake is applied,
when there are certain brake hydraulic system malfunctions as indicated by a low brake hydraulic
fluid level condition, or when the brake fluid level switch is disconnected. The brake indicator can
also give an indication when certain faults are detected in the Antilock Brake System (ABS). This
indicator is controlled by a transistor on the instrument cluster circuit board based upon cluster
programming, electronic messages received by the cluster from the Controller Antilock Brake
(CAB) over the Programmable Communications Interface (PCI) data bus, and a hard wired input
from the park brake switch.
The brake indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster
logic circuit, and that logic will only allow this indicator to operate when the instrument cluster
receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the
LED will always be off when the ignition switch is in any position except On or Start. The LED only
illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument
cluster will turn on the brake indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the brake indicator is
illuminated by the instrument cluster for about two seconds as a bulb test.
- Brake Lamp-On Message - Each time the cluster receives a lamp-on message from the CAB, the
brake indicator will be illuminated. The CAB can also send brake lamp-on messages as feedback
during ABS diagnostic procedures. The indicator remains illuminated until the cluster receives a
lamp-off message from the CAB, or until the ignition switch is turned to the Off position, whichever
occurs first.
- Park Brake Switch Input - Each time the cluster detects ground on the park brake switch sense
circuit (park brake switch closed = park brake applied or not fully released) while the ignition switch
is in the On position, the brake indicator flashes on and off. The indicator continues to flash until the
park brake switch sense input to the cluster is an open circuit (park brake switch open = park brake
fully released), or until the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the instrument cluster is put through the actuator test, the brake
indicator will be turned on, then off again during the bulb check portion of the test to confirm the
functionality of the LED and the cluster control circuitry.
The park brake switch on the park brake pedal mechanism provides a hard wired ground input to
the instrument cluster circuitry through the park brake switch sense circuit whenever the park brake
is applied or not fully released. The CAB continually monitors the ABS system circuits and sensors,
including the brake fluid level switch on the brake master cylinder reservoir, to decide whether the
system is in good operating condition. The CAB then sends the proper lamp-on or lamp-off
messages to the instrument cluster. If the CAB sends a lamp-on message after the bulb test, it
indicates that the CAB has detected a brake hydraulic system malfunction and/or that the ABS
system has become inoperative. The CAB will store a Diagnostic Trouble Code (DTC) for any
malfunction it detects.
For further diagnosis of the brake indicator or the instrument cluster circuitry that controls the LED,
refer to testing. The park brake switch input to the instrument cluster can be diagnosed using
conventional diagnostic tools and methods. For proper diagnosis of the brake fluid level switch, the
ABS, the CAB, the PCI data bus, or the electronic message inputs to the instrument cluster that
control the brake indicator, a diagnostic scan tool is required.

Parking Brake Warning Switch: Description and Operation
The park brake switch (1) is located on the park brake lever mechanism on the cowl side inner
panel below the instrument panel, to the left of the steering column. This switch includes a
spade-type output terminal (3) that connects the switch to the vehicle electrical system through a
dedicated take out and connector of the body wire harness. The output terminal is integral to the
stationary contact within a molded plastic insulator.
A locating tab on the insulator engages a slot in the park brake lever mechanism for positive switch
location. External to the insulator is a movable leaf contact with an integral grounding lug (4) on
one end and an integral actuating lever and follower (2) on the opposite end. The switch is secured
to and grounded by a single screw to the park brake lever mechanism. The park brake switch
cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
The park brake switch is a normally closed, mechanically actuated leaf contact switch that is
operated by the park brake lever mechanism. The switch is grounded through its mounting to the
park brake lever mechanism and provides a ground input to the ElectroMechanical Instrument
Cluster (EMIC) (also sometimes referred to as the Cab Control Node/CCN) on a park brake switch
sense circuit whenever the park brake is applied, and opens this circuit whenever the park brake is
released. The park brake switch sense input to the EMIC is used for control of the brake indicator
and may also be used as a logic input for other electronic features in the vehicle.
The park brake switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the EMIC processing of the park brake switch sense input requires the
use of a diagnostic scan tool.

Information > Description and Operation
Seat Belt Reminder Lamp: Description and Operation
A seatbelt indicator is standard equipment on all instrument clusters. The seatbelt indicator is
located near the upper edge of the instrument cluster, between the tachometer and the
speedometer.
The seatbelt indicator consists of a stencil-like cutout of the International Control and Display
Symbol icon for "Seat Belt" in the opaque layer of the instrument cluster overlay. The dark outer
layer of the overlay prevents the indicator from being clearly visible when it is not illuminated. A red
Light Emitting Diode (LED) behind the cutout in the opaque layer of the overlay causes the icon to
appear in red through the translucent outer layer of the overlay when the indicator is illuminated
from behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The
seatbelt indicator is serviced as a unit with the instrument cluster.
The seatbelt indicator gives an indication to the vehicle operator of the status of the driver side front
seatbelt. This indicator is controlled by a transistor on the instrument cluster circuit board based
upon cluster programming and a hard wired input from the seatbelt switch in the driver side front
seatbelt buckle through the seat belt indicator driver circuit.
The seatbelt indicator also includes a programmable enhanced seatbelt reminder or "beltminder"
feature that is enabled when the vehicle is shipped from the factory. This beltminder feature can be
disabled and enabled by the customer using a specific programming event sequence, or by the
dealer using a diagnostic scan tool.
The seatbelt indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster
logic circuit, and that logic will only allow this indicator to operate when the instrument cluster
receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the
LED will always be off when the ignition switch is in any position except On or Start. The LED only
illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument
cluster will turn on the seatbelt indicator for the following reasons:
- Seatbelt Reminder Function - Each time the cluster receives a battery current input on the fused
ignition switch output (run-start) circuit, the indicator will be illuminated as a seatbelt reminder for
about six seconds, or until the ignition switch is turned to the Off position, whichever occurs first.
This reminder function will occur regardless of the status of the seatbelt switch input to the cluster.
- Driver Side Front Seatbelt Not Buckled - Beltminder Active - Following the seatbelt reminder
function, each time the cluster detects an open circuit on the seat belt indicator driver circuit
(seatbelt switch open = seatbelt unbuckled) with the ignition switch in the Start or On positions, the
indicator will be illuminated. In addition, if the driver side front seat belt remains unbuckled about
sixty seconds after the conclusion of the seatbelt reminder function with the vehicle speed greater
than about 13 kilometers-per-hour (8 miles-per-hour), the seatbelt indicator will begin to cycle
between flashing on and off for five seconds, then lighting solid for three seconds. The seatbelt
indicator will continue to cycle between flashing and solid illumination for twelve complete cycles,
until the seat belt indicator driver input to the cluster is closed to ground (seatbelt switch closed =
seatbelt buckled), or until the ignition switch is turned to the Off position, whichever occurs first.
- Driver Side Front Seatbelt Not Buckled - Beltminder Inactive - Following the seatbelt reminder
function, each time the cluster detects an open circuit on the seat belt indicator driver circuit
(seatbelt switch open = seatbelt unbuckled) with the ignition switch in the Start or On positions, the
indicator will be illuminated. The seatbelt indicator remains illuminated until the seat belt indicator
driver input to the cluster is closed to ground (seatbelt switch closed = seatbelt buckled), or until the
ignition switch is turned to the Off position, whichever occurs first.
- Airbag Indicator Backup - If the instrument cluster detects a fault in the airbag indicator circuit it
will send a message indicating the fault to the Airbag Control Module (ACM), store a Diagnostic
Trouble Code (DTC) in the cluster memory, then flash the seatbelt indicator on and off. The cluster
will continue to flash the seatbelt indicator until the airbag indicator circuit fault is resolved, or until
the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the seatbelt indicator will be
turned on, then off again during the bulb check portion of the test to confirm the functionality of the
LED and the cluster control circuitry.
The seatbelt switch is connected in series between ground and the seat belt indicator driver input
to the instrument cluster. The seatbelt switch input to the instrument cluster circuitry may be
diagnosed using conventional diagnostic tools and methods.
For further diagnosis of the seatbelt indicator or the instrument cluster circuitry that controls the
LED, refer to testing.

Door Switch: Description and Operation
This vehicle has up to four door ajar switches, one for each door. Each switch is concealed within
and integral to its respective door latch unit. The switches are momentary leaf contact-type units
that are actuated by the mechanisms internal to the door latch. A short pigtail wire and connector
on each door latch connects the door ajar switch to the vehicle electrical system through its
respective door wire harness. The door ajar switches cannot be adjusted or repaired and, if faulty
or damaged, the door latch unit must be replaced.
The door ajar switches are actuated by the mechanisms internal to the door latch. When a door is
closed and properly latched, its door ajar switch is an open circuit. When a door is open or only
partially latched, the door ajar switch is a closed circuit. The door ajar switches are hard wired in
series between a body ground and the Electro-Mechanical Instrument Cluster (EMIC). The EMIC
reads the hard wired door ajar switch inputs through internal pull-ups, then uses these inputs to
control many electronic functions and features of the vehicle.
The EMIC also sends the proper switch status messages to other electronic modules over the
Programmable Communications Interface (PCI) data bus network. The door ajar switches can be
diagnosed and tested using conventional diagnostic tools and methods. However, conventional
diagnostic methods may not prove conclusive in the diagnosis of the EMIC, the PCI data bus, or
the electronic messaging used to convey door ajar switch status to other modules in the vehicle.
The most reliable, efficient, and accurate means to diagnose the EMIC, the PCI data bus, and both
the hard wired and electronic message inputs and outputs affected by the door ajar switch inputs
requires the use of a diagnostic scan tool.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Sensors and Switches - Instrument Panel
> Fuel Gauge Sender > Component Information > Diagrams > Diagram Information and Instructions > Page 7949
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Sensors and Switches - Instrument Panel
> Fuel Gauge Sender > Component Information > Diagrams > Diagram Information and Instructions > Page 7965
- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Sensors and Switches - Instrument Panel
> Fuel Gauge Sender > Component Information > Diagrams > Page 7966
Fuel Gauge Sender: Description and Operation
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant current source is supplied to the resistor track on the fuel
gauge sending unit. This is fed directly from the Powertrain Control Module (PCM).
NOTE: For diagnostic purposes, this 12V power source can only be verified with the circuit opened
(fuel pump module electrical connector unplugged). With the connectors plugged, output voltages
will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about 8.6 volts at EMPTY for
Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The resistor track is used to
vary the voltage (resistance) depending on fuel tank float level. As fuel level increases, the float
and arm move up, which decreases voltage. As fuel level decreases, the float and arm move down,
which increases voltage. The varied voltage signal is returned back to the PCM through the sensor
return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/ setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Parking Brake Warning Switch: Description and Operation
The park brake switch (1) is located on the park brake lever mechanism on the cowl side inner
panel below the instrument panel, to the left of the steering column. This switch includes a
spade-type output terminal (3) that connects the switch to the vehicle electrical system through a
dedicated take out and connector of the body wire harness. The output terminal is integral to the
stationary contact within a molded plastic insulator.
A locating tab on the insulator engages a slot in the park brake lever mechanism for positive switch
location. External to the insulator is a movable leaf contact with an integral grounding lug (4) on
one end and an integral actuating lever and follower (2) on the opposite end. The switch is secured
to and grounded by a single screw to the park brake lever mechanism. The park brake switch
cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
The park brake switch is a normally closed, mechanically actuated leaf contact switch that is
operated by the park brake lever mechanism. The switch is grounded through its mounting to the
park brake lever mechanism and provides a ground input to the ElectroMechanical Instrument
Cluster (EMIC) (also sometimes referred to as the Cab Control Node/CCN) on a park brake switch
sense circuit whenever the park brake is applied, and opens this circuit whenever the park brake is
released. The park brake switch sense input to the EMIC is used for control of the brake indicator
and may also be used as a logic input for other electronic features in the vehicle.
The park brake switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the EMIC processing of the park brake switch sense input requires the
use of a diagnostic scan tool.

Description and Operation
Shift Indicator: Description and Operation
An electronic automatic transmission gear selector indicator is standard factory-installed equipment
on this model. However, on vehicles not equipped with an optional automatic transmission, this
indicator is electronically disabled. The gear selector indicator information is displayed in an
electronic, blue-green Vacuum-Fluorescent Display (VFD) unit. The VFD unit is soldered onto the
cluster electronic circuit board and is visible through a window with a smoked clear lens located on
the lower edge of the speedometer gauge dial face of the cluster overlay. The dark lens over the
VFD prevents the indicator from being clearly visible when it is not illuminated.
The gear selector indicator VFD displays the following characters from left to right: "P," "R," "N,"
"D," "2," and "1". Respectively, these characters represent the park, reverse, neutral, drive, second
gear, and first gear positions of the transmission gear selector lever on the steering column. The
VFD illuminates a rectangular box around the character that represents the currently selected lever
position.
During daylight hours (exterior lamps Off) the gear selector VFD is illuminated at full brightness for
clear visibility. At night (exterior lamps are On), the VFD lighting level is adjusted with the other
cluster illumination lamps using the panel lamps dimmer thumbwheel on the headlamp switch.
However, a "Parade" mode position of the panel lamps dimmer thumbwheel allows the VFD to be
illuminated at full brightness if the exterior lamps are turned On during daylight hours. The gear
selector indicator VFD is serviced as a unit with the instrument cluster.
The electronic gear selector indicator gives an indication to the vehicle operator of the transmission
gear that has been selected with the automatic transmission gear selector lever. This indicator is
controlled by the instrument cluster circuit board based upon cluster programming. The cluster
circuitry automatically configures itself for the proper transmission and automatic transmission
model based upon the hard wired transmission range sensor mux circuit input to the cluster.
The gear selector indicator information is displayed by a dedicated Vacuum Fluorescent Display
(VFD) unit soldered onto the instrument cluster electronic circuit board, and the VFD will not display
the gear selector indicator information after the ignition switch is turned to the Off position. Each
time the cluster is disconnected from battery current for more than about five minutes, it must
configure itself for the automatic transmission model that is in the vehicle once it is reconnected to
battery current. The instrument cluster circuitry configures the gear selector indicator VFD based
upon the following inputs from the transmission range sensor:
- Open Circuit - If the cluster is configured for an automatic transmission and the transmission
range sensor mux circuit is open, the cluster circuitry controls the gear selector indicator display
based upon electronic messages received from the electronic Transmission Control Module ( TCM)
over the Programmable Communications Interface (PCI) data bus. If the transmission range sensor
mux circuit is open and no electronic messages are received from the TCM within two seconds, the
instrument cluster circuitry will not display any gear selector position until the condition is resolved
or until the ignition switch is turned to the Off position, whichever occurs first.
- Resolved Circuit - If the transmission range sensor mux circuit is resolved, the cluster circuitry
controls the gear selector indicator display based upon the resistance value of the hard wired input
from the transmission range sensor. If the cluster is configured for an automatic transmission with a
transmission range sensor input and detects a short to ground or an open in the transmission
range sensor mux input, the instrument cluster circuitry will not display any gear selector position in
the VFD. The VFD display for the short-to-ground and open circuit conditions will continue until the
condition is resolved or until the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gear selector indicator
VFD will display all of its characters at once during the VFD portion of the test to confirm the
functionality of the VFD and the cluster control circuitry.
On models with a TCM, the TCM continually monitors the transmission range sensor, then sends
the proper gear selector indicator position messages to the instrument cluster. On models without a
TCM, the instrument cluster continually monitors the hard wired transmission range sensor
multiplexed input.
On models with a TCM, for proper diagnosis of the transmission range sensor, the TCM, the PCI
data bus, or the electronic message inputs to the instrument cluster that control the gear selector
indicator, a diagnostic scan tool is required.

Information > Description and Operation
Speedometer Head: Description and Operation
A speedometer is standard equipment on all instrument clusters. The speedometer is located next
to the tachometer, just to the right of center in the instrument cluster. The speedometer consists of
a movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 210
degree primary scale on the gauge dial face. For all models except SRT-10 the speedometer reads
left-to-right either from "0" to "120" mph, or from "0" to "200" km/h, depending upon the market for
which the vehicle is manufactured. On SRT-10 the speedometer reads left-to-right either from "0"
to "160" mph, or from "0" to "280" km/h, depending upon the market for which the vehicle is
manufactured. Each version also has a secondary inner scale on the gauge dial face that provides
the equivalent opposite units from the primary scale.
Text appearing on the cluster overlay just below the hub of the speedometer needle abbreviates
the unit of measure for the primary scale (i.e.: MPH or km/h), followed by the unit of measure for
the secondary scale. The speedometer graphics for all models except SRT-10 are black (primary
scale) and blue (secondary scale) against a white field. On SRT-10 the gauge graphics are black
(primary scale) and gray (secondary scale) against a silver field and also includes a line of text
identifying this as a "Performance Vehicle Operations" product. In either case, the gauge graphics
are clearly visible within the instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned On, the black graphics appear blue-green and the blue or gray
graphics appear light blue. The gauge needle has internal optical illumination. Gauge illumination is
provided by replaceable incandescent bulb and holder units located on the instrument cluster
electronic circuit board. The speedometer is serviced as a unit with the instrument cluster.
The speedometer gives an indication to the vehicle operator of the relative vehicle road speed. This
gauge is controlled by the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) over the
Programmable Communications Interface (PCI) data bus.
The speedometer is an air core magnetic unit that receives battery current on the instrument
cluster electronic circuit board through the fused ignition switch output (run-start) circuit whenever
the ignition switch is in the On or Start positions. The cluster is programmed to move the gauge
needle back to the low end of the scale after the ignition switch is turned to the Off position. The
instrument cluster circuitry controls the gauge needle position and provides the following features:
- Vehicle Speed Message - Each time the cluster receives a vehicle speed message from the PCM
it will calculate the correct vehicle speed reading and position the gauge needle at that relative
speed position on the gauge scale. The cluster will receive a new vehicle speed message and
reposition the gauge pointer accordingly about every 88 milliseconds. The gauge needle will
continually be positioned at the relative vehicle speed position on the gauge scale until the vehicle
stops moving, or until the ignition switch is turned to the Off position, whichever occurs first.
- Communication Error - If the cluster fails to receive a speedometer message, it will hold the
gauge needle at the last indication for about ten seconds, or until the ignition switch is turned to the
Off position, whichever occurs first. After ten seconds, the gauge needle will return to the left end of
the gauge scale.
- Actuator Test - Each time the cluster is put through the actuator test, the speedometer needle will
be swept to several calibration points on the gauge scale in a prescribed sequence in order to
confirm the functionality of the gauge and the cluster control circuitry.
The PCM continually monitors the vehicle speed sensor or the Controller Anti-lock Brake (CAB) to
determine the vehicle road speed. The PCM then sends the proper vehicle speed messages to the
instrument cluster. For further diagnosis of the speedometer or the instrument cluster circuitry that
controls the gauge, refer to testing.
For proper diagnosis of the vehicle speed sensor, the CAB, the PCM, the PCI data bus, or the
electronic message inputs to the instrument cluster that control the speedometer, a diagnostic scan
tool is required.

Description and Operation
Tachometer: Description and Operation
A tachometer is standard equipment on all instrument clusters. The tachometer is located to the left
of the speedometer, just to the left of center in the instrument cluster. The tachometer consists of a
movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 210
degree scale on the gauge dial face. The tachometer reads left-to-right from "0" to "7" for gasoline
engines. On vehicles with a diesel engine, the scale reads from "0" to "5".
On all models except SRT-10, the text "RPM X 1000" is imprinted on the cluster overlay directly
below the hub of the tachometer needle. On SRT-10 models the text "X 1000 RPM" is imprinted on
the cluster overlay directly below the hub of the tachometer needle. This text identifies that each
number on the tachometer scale is to be multiplied by 1000 rpm.
On all models except SRT-10 the tachometer graphics are black against a white field, making them
clearly visible within the instrument cluster in daylight. On SRT-10 the tachometer graphics are
black against a silver field except for red graduations beginning at the "6" increment and at each
250 rpm increment to the "7" at the high end of the scale. The SRT-10 tachometer also includes
the text, "Premium Unleaded Fuel Only." In either case, the gauge graphics are clearly visible
within the instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned On, the black graphics appear blue-green and the red graphics still
appear red. The gauge needle has internal optical illumination. Gauge illumination is provided by a
replaceable incandescent bulb and holder unit located on the instrument cluster electronic circuit
board. The tachometer is serviced as a unit with the instrument cluster.
The tachometer gives an indication to the vehicle operator of the engine speed. This gauge is
controlled by the instrument cluster circuit board based upon cluster programming and electronic
messages received by the cluster from the Powertrain Control Module (PCM) on vehicles with a
gasoline engine, or from the Engine Control Module (ECM) on vehicles equipped with a diesel
engine over the Programmable Communications Interface (PCI) data bus.
The tachometer is an air core magnetic unit that receives battery current on the instrument cluster
electronic circuit board through the fused ignition switch output (run-start) circuit whenever the
ignition switch is in the On or Start positions. The cluster is programmed to move the gauge needle
back to the low end of the scale after the ignition switch is turned to the Off position. The instrument
cluster circuitry controls the gauge needle position and provides the following features:
- Engine Speed Message - Each time the cluster receives an engine speed message from the PCM
or ECM it will calculate the correct engine speed reading and position the gauge needle at that
relative engine speed position on the gauge scale. The cluster will receive a new engine speed
message and reposition the gauge pointer accordingly about every 88 milliseconds. The gauge
needle will continually be repositioned at the relative engine speed position on the gauge scale until
the engine stops running, or until the ignition switch is turned to the Off position, whichever occurs
first.
- Communication Error - If the cluster fails to receive an engine speed message, it will hold the
gauge needle at the last indication for about ten seconds, or until the ignition switch is turned to the
Off position, whichever occurs first. After ten seconds, the gauge needle will return to the left end of
the gauge scale.
Actuator Test - Each time the cluster is put through the actuator test, the tachometer needle will be
swept to several calibration points on the gauge scale in a prescribed sequence in order to confirm
the functionality of the gauge and the cluster control circuitry
On vehicles with a gasoline engine, the PCM continually monitors the crankshaft position sensor to
determine the engine speed. On vehicles with a diesel engine, the ECM continually monitors the
engine speed sensor to determine the engine speed. The PCM or ECM then sends the proper
engine speed messages to the instrument cluster. For further diagnosis of the tachometer or the
instrument cluster circuitry that controls the gauge, refer to testing.
For proper diagnosis of the crankshaft position sensor, the engine speed sensor, the PCM, the
ECM, the PCI data bus, or the electronic message inputs to the instrument cluster that control the
tachometer, a diagnostic scan tool is required.

Information > Description and Operation
Temperature Gauge: Description and Operation
An engine coolant temperature gauge is standard equipment on all instrument clusters. The engine
coolant temperature gauge is located in the lower right quadrant of the instrument cluster, below
the oil pressure gauge. The engine coolant temperature gauge consists of a movable gauge needle
or pointer controlled by the instrument cluster circuitry and a fixed 90 degree scale on the cluster
overlay that reads left-to-right from "C" (or Cold) to "H" (or Hot) for gasoline engines except
SRT-10. On SRT-10 models, the scale reads from "60"° C to "120"° C in markets where a metric
instrument cluster is specified, or from "140"° F to "260"° F in all other markets. On vehicles with a
diesel engine, the scale reads from "60"° C to "120"° C in markets where a metric instrument
cluster is specified, or from "140"° F to "245"° F in all other markets. An International Control and
Display Symbol icon for "Engine Coolant Temperature" is located on the cluster overlay directly
below the left end of the gauge scale.
On all models except SRT-10 the engine coolant temperature gauge graphics are black against a
white field except for two red graduations at the high end of the gauge scale. On SRT-10 the gauge
graphics are black against a silver field except for a single red zone at the high end of the gauge
scale. In either case, the gauge graphics are clearly visible within the instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned On, the black gauge graphics appear blue-green and the red
graphics still appear red. The gauge needle has internal optical illumination. Gauge illumination is
provided by replaceable incandescent bulb and holder units located on the instrument cluster
electronic circuit board. The engine coolant temperature gauge is serviced as a unit with the
instrument cluster.
The engine coolant temperature gauge gives an indication to the vehicle operator of the engine
coolant temperature. This gauge is controlled by the instrument cluster circuit board based upon
cluster programming and electronic messages received by the cluster from the Powertrain Control
Module (PCM) on vehicles equipped with a gasoline engine, or from the Engine Control Module
(ECM) on vehicles equipped with a diesel engine over the Programmable Communications
Interface (PCI) data bus.
The engine coolant temperature gauge is an air core magnetic unit that receives battery current on
the instrument cluster electronic circuit board through the fused ignition switch output (run-start)
circuit whenever the ignition switch is in the On or Start positions. The cluster is programmed to
move the gauge needle back to the low end of the scale after the ignition switch is turned to the Off
position. The instrument cluster circuitry controls the gauge needle position and provides the
following features:
- Engine Temperature Message - Each time the cluster receives a message from the PCM or ECM
indicating the engine coolant temperature is between the low end of normal [about 54° C (130° F)
for gasoline engines except SRT-10, or about 60° C (140° F) for SRT-10 and diesel engines] and
the high end of normal [about 122° C (252° F) for gasoline engines, about or about 116° C (240° F)
for diesel engines], the gauge needle is moved to the actual relative temperature position on the
gauge scale.
- Engine Temperature Low Message - Each time the cluster receives a message from the PCM or
ECM indicating the engine coolant temperature is below the low end of normal [about 54° C (130°
F) for gasoline engines except SRT-10, or about 60° C (140° F) for SRT-10 and diesel engines],
the gauge needle is held at the graduation on the far left end of the gauge scale. The gauge needle
remains at the left end of the gauge scale until the cluster receives a message from the PCM or
ECM indicating that the engine temperature is above about 54° C (130° F) for gasoline engines
except SRT-10, or about 60° C (140° F) for SRT-10 and diesel engines, or until the ignition switch
is turned to the Off position, whichever occurs first.
- Engine Temperature High Message - Each time the cluster receives three consecutive bus
messages from the PCM or ECM indicating the engine coolant temperature is above about 122° C
(252° F) for gasoline engines, or about 116° C (240° F) for diesel engines, the gauge needle is
moved into the red zone at the far right end of gauge scale, the check gauges indicator is
illuminated, and a single chime tone is sounded. The gauge needle remains in the red zone and
the check gauges indicator remains illuminated until the cluster receives a message from the PCM
or ECM indicating that the engine temperature is below about 122° C (252° F) for gasoline engines,
or about 116° C (240° F) for diesel engines, or until the ignition switch is turned to the Off position,
whichever occurs first. The chime tone feature will only repeat during the same ignition cycle if the
check gauges indicator is cycled off and then on again by the appropriate engine temperature
messages from the PCM or ECM.
- Communication Error - If the cluster fails to receive an engine temperature message, it will hold
the gauge needle at the last indication for about ten seconds, or until the ignition switch is turned to
the Off position, whichever occurs first. After ten seconds, the cluster will move the gauge needle to
the low end of the gauge scale.
- Actuator Test - Each time the cluster is put through the actuator test, the engine coolant
temperature gauge needle will be swept to several calibration points on the gauge scale in a
prescribed sequence in order to confirm the functionality of the gauge and the cluster control
circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the engine coolant temperature
sensor to determine the engine operating temperature. On vehicles with a diesel engine, the ECM
continually monitors the engine coolant temperature sensor to determine the engine operating
temperature. The PCM or ECM then sends the proper engine coolant temperature messages to the
instrument cluster. If the instrument cluster turns on the check gauges indicator due to a high
engine temperature gauge reading, it may indicate that the engine or the engine cooling system
requires service.
For proper diagnosis of the engine coolant temperature sensor, the PCM, the ECM, the PCI data
bus, or the electronic message inputs to the instrument cluster that control the engine coolant
temperature gauge, a diagnostic scan tool is required.

Temperature Warning Indicator - A/T: Description and Operation
A transmission over-temperature indicator is standard equipment on all instrument clusters.
However, on vehicles not equipped with an optional automatic transmission, this indicator is
electronically disabled. This indicator is located on the left side of the instrument cluster, to the left
of the fuel gauge.
The transmission over-temperature indicator consists of a stencil-like cutout of the text "TRANS
TEMP" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. A red Light Emitting
Diode (LED) behind the cutout in the opaque layer of the overlay causes the "TRANS TEMP" text
to appear in red through the translucent outer layer of the overlay when the indicator is illuminated
from behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The
transmission over-temperature indicator is serviced as a unit with the instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
transmission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus.
The transmission over-temperature indicator Light Emitting Diode (LED) is completely controlled by
the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the
instrument cluster receives a battery current input on the fused ignition switch output (run-start)
circuit. Therefore, the LED will always be off when the ignition switch is in any position except On
or Start. The LED only illuminates when it is provided a path to ground by the instrument cluster
transistor. The instrument cluster will turn on the transmission over-temperature indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the On position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-On Message - Each time the cluster receives a trans over-temp lamp-on
message from the PCM indicating that the transmission fluid temperature is 135° C (275° F) or
higher, the indicator will be illuminated and a single chime tone is sounded. The indicator remains
illuminated until the cluster receives a trans over-temp lamp-off message from the PCM, or until the
ignition switch is turned to the Off position, whichever occurs first. The chime tone feature will only
repeat during the same ignition cycle if the transmission over-temperature indicator is cycled off
and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the transmission
over-temperature indicator will be turned on, then off again during the bulb check portion of the test
to confirm the functionality of the LED and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition. The PCM then sends the proper trans over-temp lamp-on or lamp-off
messages to the instrument cluster. If the instrument cluster turns on the transmission
over-temperature indicator due to a high transmission oil temperature condition, it may indicate that
the transmission and/or the transmission cooling system are being overloaded or that they require
service. For further diagnosis of the transmission over-temperature indicator or the instrument
cluster circuitry that controls the LED.
For proper diagnosis of the transmission temperature sensor, the PCM, the PCI data bus, or the
electronic message inputs to the instrument cluster that control the transmission over-temperature
indicator, a diagnostic scan tool is required.

Information > Description and Operation
Upshift Indicator: Description and Operation
An upshift indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with a manual transmission, or on vehicles equipped with a manual transmission but sold
in a market where this is not required equipment, this indicator is electronically disabled.
The upshift indicator consists of an upward pointed arrow icon, which appears on the right side of
the electronic gear selector indicator Vacuum Fluorescent Display (VFD) unit. The VFD is soldered
onto the cluster electronic circuit board and is visible through a window with a smoked clear lens
located on the lower edge of the speedometer gauge dial face of the cluster overlay. The dark lens
over the VFD prevents the indicator from being clearly visible when it is not illuminated. The icon
appears in a blue-green color and at the same lighting level as the odometer/trip odometer
information when it is illuminated by the instrument cluster electronic circuit board. The upshift
indicator is serviced as a unit with the instrument cluster.
The upshift indicator gives an indication to the vehicle operator when the manual transmission
should be shifted to the next highest gear in order to achieve the best fuel economy. This indicator
is controlled by the instrument cluster circuit board based upon cluster programming and electronic
messages received by the cluster from the Powertrain Control Module (PCM) on vehicles with a
gasoline engine, or from the Engine Control Module (ECM) on vehicles with a diesel engine over
the Programmable Communications Interface (PCI) data bus.
The upshift indicator is completely controlled by the instrument cluster logic circuit, and that logic
will only allow this indicator to operate when the instrument cluster receives a battery current input
on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
upshift indicator for the following reasons:
- Upshift Lamp-On Message - Each time the cluster receives an upshift lamp-on message from the
PCM or ECM indicating the engine speed and load conditions are right for a transmission upshift to
occur, the upshift indicator is illuminated. The indicator remains illuminated until the cluster
receives an upshift lamp-off message from the PCM or ECM, or until the ignition switch is turned to
the Off position, whichever occurs first. The PCM or ECM will normally send an upshift lamp-off
message three to five seconds after a lamp-on message, if an upshift is not performed. The
indicator will then remain off until the vehicle stops accelerating and is brought back into the range
of indicator operation, or until the transmission is shifted into another gear.
- Actuator Test - Each time the cluster is put through the actuator test, the upshift indicator will be
turned on, then off again during the VFD portion of the test to confirm the functionality of the VFD
and the cluster control circuitry.
On vehicles with a gasoline engine, the PCM continually monitors the engine speed and load
conditions to determine the proper fuel and ignition requirements. On vehicles with a diesel engine,
the ECM continually monitors the engine speed and load conditions to determine the proper fuel
requirements. The PCM or ECM then sends the proper upshift indicator lamp-on and lamp-off
messages to the instrument cluster. For further diagnosis of the upshift indicator or the instrument
cluster circuitry that controls the indicator, refer to testing.
For proper diagnosis of the PCM, the ECM, the PCI data bus, or the electronic message inputs to
the instrument cluster that control the upshift indicator, a diagnostic scan tool is required.

Volt Meter Gauge: Description and Operation
A voltage gauge is standard equipment on all instrument clusters. The voltage gauge is located in
the upper left quadrant of the instrument cluster, above the fuel gauge.
The voltage gauge consists of a movable gauge needle or pointer controlled by the instrument
cluster circuitry and a fixed 90 degree scale on the cluster overlay that reads left-to-right from "L"
(or Low) to "H" (or High) for gasoline engines except SRT-10. On SRT-10 models, the scale reads
from "10" to "18" volts. On vehicles with a diesel engine, the scale reads from "8" to "18" volts.
An International Control and Display Symbol icon for "Battery Charging Condition" is located on the
cluster overlay, directly below the right end of the gauge scale. On all models except SRT-10 the
voltage gauge graphics are black against a white field except for a single red graduation at each
end of the gauge scale. On SRT-10 the gauge graphics are black against a silver field except for a
single red graduation at the left end of the gauge scale and two red graduations at the right end of
the gauge scale. In either case, the gauge graphics are clearly visible within the instrument cluster
in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned On, the black graphics appear blue-green and the red graphics still
appear red. The gauge needle has internal optical illumination. Gauge illumination is provided by a
replaceable incandescent bulb and holder unit located on the instrument cluster electronic circuit
board. The voltage gauge is serviced as a unit with the instrument cluster.
The voltage gauge gives an indication to the vehicle operator of the electrical system voltage. This
gauge is controlled by the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) on vehicles
equipped with a gasoline engine, or from the Engine Control Module (ECM) on vehicles equipped
with a diesel engine over the Programmable Communications Interface (PCI) data bus.
The voltage gauge is an air core magnetic unit that receives battery current on the instrument
cluster electronic circuit board through the fused ignition switch output (run-start) circuit whenever
the ignition switch is in the On or Start positions. The cluster is programmed to move the gauge
needle back to the left end of the scale after the ignition switch is turned to the Off position. The
instrument cluster circuitry controls the gauge needle position and provides the following features:
- System Voltage Message - Each time the cluster receives a system voltage message from the
PCM or ECM indicating the system voltage is between about 9.5 volts and about 15 volts, the
gauge needle is moved to the relative voltage position on the gauge scale.
- System Voltage Low (Charge Fail) Message - Each time the cluster receives three consecutive
messages from the PCM or ECM indicating the electrical system voltage is less than about 9 volts
(charge fail condition) or that the battery temperature sensor input is an open circuit, the gauge
needle is moved to the graduation on the far left end of the gauge scale and the check gauges
indicator is illuminated. The gauge needle remains at the far left end of the gauge scale and the
check gauges indicator remains illuminated until the cluster receives a single message from the
PCM or ECM indicating the electrical system voltage is greater than about 9.5 volts (but less than
about 15.5 volts), or until the ignition switch is turned to the Off position, whichever occurs first. On
vehicles equipped with the optional diesel engine, the ECM is programmed to restrict the voltage
gauge needle to a position above the graduation on the far left end of the gauge scale and
suppress the check engine indicator operation until after the engine intake manifold air heater has
completed a pre-heat or post-heat cycle.
- System Voltage High Message - On all models except SRT-10, each time the cluster receives
three consecutive messages from the PCM or ECM indicating the electrical system voltage is
greater than about 15.5 volts, the gauge needle is moved to the graduation on the far right end of
the gauge scale and the check gauges indicator is illuminated. The gauge needle remains at the
right end of the gauge scale and the check gauges indicator remains illuminated until the cluster
receives a message from the PCM or ECM indicating the electrical system voltage is less than
about 15.0 volts (but greater than about 9.5 volts), or until the ignition switch is turned to the Off
position, whichever occurs first. On SRT-10, each time the cluster receives three consecutive
messages from the PCM indicating the electrical system voltage is greater than about 15.5 volts,
the gauge needle is moved to the 16 volt graduation of the gauge scale and the check gauges
indicator is illuminated. The gauge needle remains at or above the 16 volt graduation of the gauge
scale and the check gauges indicator remains illuminated until the cluster receives a message from
the PCM indicating the electrical system voltage is less than about 15.0 volts (but greater than
about 9.5 volts), or until the ignition switch is turned to the Off position, whichever occurs first.
- Communication Error - If the cluster fails to receive a system voltage message, it will hold the
gauge needle at the last indication for about ten seconds, or until the ignition switch is turned to the
Off position, whichever occurs first. After ten seconds, the cluster will move the gauge needle to the
far left end of the gauge scale.
- Actuator Test - Each time the cluster is put through the actuator test, the voltage gauge needle
will be swept to several calibration points on the gauge scale in a prescribed sequence in order to
confirm the functionality of the gauge and the cluster control circuitry
On vehicles with a gasoline engine, the PCM continually monitors the system voltage to control the
generator output. On vehicles with a diesel engine, the ECM continually monitors the system
voltage to control the generator output. The PCM or ECM then sends the proper system voltage
messages to the instrument cluster. For further diagnosis of the voltage gauge or the instrument
cluster circuitry that controls the gauge, refer to testing. If the instrument cluster turns on the check
gauges indicator due to a charge fail or voltage high condition, it may indicate that the charging
system requires service.

scan tool is required.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Lighting and Horns > Backup Lamp > Backup Lamp Switch > Component Information >
Diagrams > Diagram Information and Instructions > Page 8019
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Backup Lamp Switch: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

Fig.7 Testing For Voltage Potential
STANDARD PROCEDURE - TESTING OF VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

Fig.9 Testing For Voltage Drop
STANDARD PROCEDURE - TESTING FOR A VOLTAGE DROP
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery (Fig. 9).
2. Connect the other lead of the voltmeter to the other side of the switch, component or circuit. 3.
Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.

Backup Lamp Switch: Description and Operation
Vehicles equipped with a manual transmission have a normally open, spring-loaded plunger type
backup lamp switch (2). Vehicles with an optional electronic automatic transmission have a
Transmission Range Sensor (TRS) that is used to perform several functions, including that of the
backup lamp switch. The Transmission Range Sensor (TRS) is part of the solenoid module, which
is mounted to the top of the valve body inside the automatic transmission.
The backup lamp switch is located in a threaded hole on the side of the manual transmission
housing. The switch has a threaded body and a hex formation near the plunger end of the switch.
An integral connector receptacle at the end of the switch opposite the plunger connects the switch
to the vehicle electrical system through a take out and connector of the engine wire harness. When
installed, only the switch connector and the hex formation are visible on the outside of the
transmission housing. The backup lamp switch cannot be adjusted or repaired and, if faulty or
damaged, the entire switch unit must be replaced.
The backup lamp switch controls the flow of battery voltage to the backup lamp bulbs through an
output on the backup lamp feed circuit. The switch plunger is mechanically actuated by the
gearshift mechanism within the transmission, which will depress the switch plunger and close the
switch contacts whenever the reverse gear has been selected. The switch receives battery voltage
through a fuse in the Integrated Power Module (IPM) on a fused ignition switch output (run) circuit
whenever the ignition switch is in the On position. The backup lamp switch and circuits can be
tested using conventional diagnostic tools and methods.

Brake Lamp: Description and Operation
The brake (or stop) lamps each have a path to ground at all times through a takeout and eyelet
terminal of the left headlamp and dash wire harness that is secured by a ground screw to the left
inner fender support within the engine compartment. The Center High Mounted Stop Lamp
(CHMSL) has a path to ground at all times through a takeout and eyelet terminal of the instrument
panel wire harness that is secured by a ground screw to the back of the support structure of the
instrument panel near the center. The brake lamps receive battery voltage from the Front Control
Module (FCM) on the right and left brake lamp feed circuits and the CHMSL receives battery
voltage from the brake lamp switch output circuit when the brake lamp switch is closed by the
brake pedal arm.

Brake Light Switch: Description and Operation
The brake lamp switch (2) is a three circuit, spring-loaded plunger actuated switch that is secured
to the steering column support bracket under the instrument panel on the driver side of the vehicle.
The molded plastic switch housing has an integral connector receptacle (1) containing six terminal
pins and featuring a Connector Position Assurance (CPA) lock. The switch is connected to the
vehicle electrical system through a dedicated take out of the instrument panel wire harness.
The switch plunger (3) extends through a mounting collar (4) on one end of the switch housing. The
plunger has a one time telescoping self-adjustment feature that is activated after the switch is
installed by moving an adjustment release lever (5) on the opposite end of the switch housing
clockwise, until it locks into a position that is horizontal and parallel to the connector receptacle.
An installed brake lamp switch cannot be readjusted or repaired. If the switch is damaged, faulty, or
removed from its mounting position for any reason, it must be replaced with a new unit.
The brake lamp switch controls three independent circuits. These circuits are described as follows:
- Brake Lamp Switch Circuit - A normally open brake lamp switch circuit receives a battery voltage
input, and supplies this battery voltage to the brake lamps and the Controller Antilock Brake (CAB)
on a brake lamp switch output circuit only when the brake pedal is depressed (brake lamp switch
plunger released).
- Brake Lamp Switch Signal Circuit - A normally closed brake lamp switch signal circuit receives a
direct path to ground, and supplies this ground input to the Power-train Control Module (PCM) on a
brake lamp switch sense circuit only when the brake pedal is released (brake lamp switch plunger
is depressed).
- Speed Control Circuit - A normally closed speed control circuit receives a battery voltage input
from the Powertrain Control Module on a speed control supply circuit, and supplies this battery
voltage to the speed control servo solenoids (dump, vacuum, and vent) on a speed control brake
switch output circuit only when the speed control system is turned On and the brake pedal is
released (brake lamp switch plunger is depressed).
The components of the self-adjusting brake switch plunger consist of a two-piece telescoping
plunger, a split plunger locking collar, and a release wedge. The release lever has a shaft with a
wedge that spreads the plunger locking collar to an open or released position. After the switch is
installed and the brake pedal is released, the plunger telescopes to the correct adjustment position.
When the release lever is moved to the release position, the wedge is disengaged from the locking
collar causing the collar to apply a clamping pressure to the two plunger halves, fixing the plunger
length.
The brake lamp switch is diagnosed using conventional diagnostic tools and methods.

Dodge Workshop Manuals > Lighting and Horns > Cargo Lamp > Component Information > Description and Operation
Cargo Lamp: Description and Operation
A cargo lamp indicator is standard equipment on all instrument clusters. The cargo lamp indicator
is located on the right side of the instrument cluster, to the right of the oil pressure gauge.
The cargo lamp indicator consists of a stencil-like cutout of the words "CARGO LAMP" in the
opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents the
indicator from being clearly visible when it is not illuminated. An amber Light Emitting Diode (LED)
behind the cutout in the opaque layer of the overlay causes the "CARGO LAMP" text to appear in
amber through the translucent outer layer of the overlay when the indicator is illuminated from
behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The cargo
lamp indicator is serviced as a unit with the instrument cluster.
The cargo lamp indicator gives an indication to the vehicle operator when the exterior cargo lamp is
illuminated. This indicator is controlled by a transistor on the instrument cluster circuit board based
upon cluster programming, a hard wired multiplex input received by the cluster from the panel
lamps dimmer switch on the headlamp dimmer switch mux circuit, and electronic unlock request
messages received from the optional Remote Keyless Entry (RKE) module.
The cargo lamp indicator Light Emitting Diode (LED) is completely controlled by the instrument
cluster logic circuit, and that logic will only allow this indicator to operate whenever the instrument
cluster receives a battery current input on the fused ignition switch output (run-start) circuit.
Therefore, the LED will always be off when the ignition switch is in any position except On or Start.
The LED only illuminates when it is provided a path to ground by the instrument cluster transistor.
The instrument cluster will turn on the cargo lamp indicator for the following reasons:
- Cargo Lamp-On Input - Each time the cluster detects a cargo lamp-on input from the headlamp
switch on the headlamp dimmer switch mux circuit, the cargo lamp and the cargo lamp indicator
will be illuminated. The cargo lamp and indicator remain illuminated until the cluster receives a
cargo lamp-off input from the headlamp switch, until the cluster has completed an interior lamps
load shed (about five minutes), or until the ignition switch is turned to the Off position, whichever
occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the cargo lamp indicator will
be turned on, then off again during the bulb check portion of the test to confirm the functionality of
the LED and the cluster control circuitry.
The instrument cluster continually monitors the headlamp dimmer switch circuit to determine the
proper interior lamps features and panel lamps illumination levels to provide. The cluster then
energizes and de-energizes a low side driver circuit to control the exterior cargo lamp. Each time
the instrument cluster energizes the cargo lamp driver and the ignition switch is in the On or Start
positions, the cluster also turns on the cargo lamp indicator. For further diagnosis of the cargo lamp
indicator or the instrument cluster circuitry that controls the indicator, refer to testing.
For proper diagnosis of the cargo lamp or the headlamp switch inputs to the instrument cluster that
control the cargo lamp indicator, a diagnostic scan tool is required.

Dodge Workshop Manuals > Lighting and Horns > Door Switch > Component Information > Description and Operation
Door Switch: Description and Operation
This vehicle has up to four door ajar switches, one for each door. Each switch is concealed within
and integral to its respective door latch unit. The switches are momentary leaf contact-type units
that are actuated by the mechanisms internal to the door latch. A short pigtail wire and connector
on each door latch connects the door ajar switch to the vehicle electrical system through its
respective door wire harness. The door ajar switches cannot be adjusted or repaired and, if faulty
or damaged, the door latch unit must be replaced.
The door ajar switches are actuated by the mechanisms internal to the door latch. When a door is
closed and properly latched, its door ajar switch is an open circuit. When a door is open or only
partially latched, the door ajar switch is a closed circuit. The door ajar switches are hard wired in
series between a body ground and the Electro-Mechanical Instrument Cluster (EMIC). The EMIC
reads the hard wired door ajar switch inputs through internal pull-ups, then uses these inputs to
control many electronic functions and features of the vehicle.
The EMIC also sends the proper switch status messages to other electronic modules over the
Programmable Communications Interface (PCI) data bus network. The door ajar switches can be
diagnosed and tested using conventional diagnostic tools and methods. However, conventional
diagnostic methods may not prove conclusive in the diagnosis of the EMIC, the PCI data bus, or
the electronic messaging used to convey door ajar switch status to other modules in the vehicle.
The most reliable, efficient, and accurate means to diagnose the EMIC, the PCI data bus, and both
the hard wired and electronic message inputs and outputs affected by the door ajar switch inputs
requires the use of a diagnostic scan tool.

Fog/Driving Lamp Relay: Description and Operation
The front fog lamp relay is a conventional International Standards Organization (ISO) micro relay.
Relays conforming to the ISO specifications have common physical dimensions, current capacities,
terminal patterns, and terminal functions. The relay is contained within a small, rectangular, molded
plastic housing and is connected to all of the required inputs and outputs through five integral male
spade-type terminals that extend from the relay base plate.
The front fog lamp relay is located in the Power Distribution Center (PDC)See: Maintenance/Fuses
and Circuit Breakers/Relay BoxApplications and ID in the engine compartment near the battery.
Refer to the layout label on the underside of the PDC cover for specific relay cavity assignment
information. The front fog lamp relay cannot be adjusted or repaired and, if faulty or damaged, the
unit must be replaced.
The front fog lamp relay is an electromechanical switch that uses a low current input from the Front
Control Module (FCM) (also referred to as the Integrated Power Module/IPM) to control a high
current output to the front fog lamps. Within the relay are an electromagnetic coil, a movable
contact and two fixed contact points. A resistor is connected in parallel with the coil, and helps to
dissipate voltage spikes and electromagnetic interference that can be generated as the field of the
relay coil collapses.
The movable common supply contact point is held against the fixed normally closed contact point
by spring pressure. When the relay coil is energized, an electromagnetic field is produced by the
coil windings. This field draws the movable contact away from the normally closed contact, and
holds it against the normally open contact. When the relay coil is de-energized, spring pressure
returns the movable contact back against the normally closed contact.
The inputs and outputs of the front fog lamp relay include:
- Common Supply Terminal (30) - The common feed terminal is connected to a fused B(+) circuit at
all times.
- Coil Ground Terminal (85) - The coil ground terminal is connected to a fused B(+) circuit at all
times.
- Coil Battery Terminal (86) - The coil battery terminal is connected to a control output of the FCM
through a fog lamp relay control circuit. The FCM controls front fog lamp operation by controlling a
ground path through this circuit.
- Normally Open Terminal (87) - The normally open terminal is connected to the front fog lamps
through a fog lamp relay output circuit and provides battery voltage to the front fog lamps whenever
the relay is energized.
- Normally Closed Terminal (87A) - The normally closed terminal is not connected to any circuit in
this application, but will have battery voltage present whenever the relay is de-energized.
The front fog lamp relay can be diagnosed using conventional diagnostic tools and methods.

Headlamp Switch: Description and Operation
The headlamp switch (1) is located on the instrument panel, to the left of the steering column. Two
different switches are used. The standard switch features a three-position rotary knob (3) for
exterior lighting control and a thumbwheel (2) for panel lamps dimming and interior lighting control.
An optional switch has the same thumbwheel, but has an additional "Pull" function added to the
rotary knob for selecting the optional front fog lamps.
Each of these switches is constructed of molded plastic. The rotary knob is molded plastic and has
a raised center lever to ease operator control. The thumbwheel is also plastic and knurled. The
optional front fog lamp rotary knob is plastic with a smooth finish and an International Control and
Display Symbol icon for "Front Fog Light" applied to it. The switch face plate is also labeled with
graphics and icons to clearly identify the many functions of the rotary knob and thumbwheel.
Three screws secure the switch to the back of the cluster bezel through integral mounting flanges
that are molded to each side of the switch housing. The back of the switch housing has an integral
connector receptacle containing terminal pins that connect the switch to the vehicle electrical
system through a dedicated take out and connector of the instrument panel wire harness. A panel
dimmer controlled incandescent bulb soldered to the circuit board within the switch provides back
lighting for visibility at night, but is not serviceable. The headlamp switch cannot be repaired and, if
faulty or damaged, it must be replaced.
The headlamp switch uses two resistor multiplexed outputs to control the many functions and
features it provides. The switch receives a clean ground from the ElectroMechanical Instrument
Cluster (EMIC) (also sometimes referred to as the Cab Control Node/CCN) on a headlamp switch
return circuit. It then provides outputs to the EMIC on a headlamp switch signal circuit to control
exterior lighting functions, and on a panel lamps dimmer signal circuit to control panel dimmer and
interior lighting functions.
The switch illumination circuit receives a path to ground at all times through the left instrument
panel ground circuit. The illumination level is controlled by a Pulse-Width Modulated (PWM) output
received from the EMIC on a headlamp switch illumination control circuit. The EMIC controls this
output based upon the dimmer signal select mux input from the headlamp switch.
- Front Fog Lamps Control - For vehicles so equipped, the rotary knob on the headlamp switch is
pulled out to activate or pushed in to deactivate the optional front fog lamps. The headlamp switch
provides an output to the EMIC, and the EMIC responds by sending electronic fog lamp switch
status messages to the Front Control Module (FCM) over the Programmable Communications
Interface (PCI) data bus. The FCM responds by energizing or de-energizing the front fog lamp
relay in the Power Distribution Center (PDC).
- Exterior Lighting Control - The rotary knob on the headlamp switch is rotated to a detent position
to activate or deactivate the exterior lighting. The headlamp switch provides an output to the EMIC,
and the EMIC responds by sending electronic exterior lighting switch status messages to the FCM
over the PCI data bus. The FCM responds by energizing or de-energizing the park lamp relay in
the PDC and the high or low beam headlamp circuits. The FCM remembers which headlamp
beams were last selected using the multi-function switch, and energizes those beams by default
the next time the headlamps are turned On.
- Interior Lighting Control - The thumbwheel on the headlamp switch is rotated to the dome defeat,
dome on, parade/funeral mode, or one of the six panel dimmer detent positions to control the
interior courtesy/dome and panel lamps. The headlamp switch provides an output to the EMIC, and
the EMIC responds by providing the appropriate interior lighting control outputs through its internal
courtesy lamp driver circuits, electronic dimming level messages to other modules over the PCI
data bus, and/or the proper PWM outputs to control dimming levels through several panel dimmer
illumination control driver circuits.
The headlamp switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the multiplexed inputs to and PWM processing of the EMIC requires the
use of a diagnostic scan tool.

Dodge Workshop Manuals > Lighting and Horns > Hi-Beam Indicator Lamp > Component Information > Description and
Operation
Hi-Beam Indicator Lamp: Description and Operation
A high beam indicator is standard equipment on all instrument clusters. This indicator is located
near the upper edge of the instrument cluster, between the tachometer and the speedometer.
The high beam indicator consists of a stencil-like cutout of the International Control and Display
Symbol icon for "High Beam" in the opaque layer of the instrument cluster overlay. The dark outer
layer of the overlay prevents the indicator from being clearly visible when it is not illuminated. A
blue Light Emitting Diode (LED) behind the cutout in the opaque layer of the overlay causes the
icon to appear in blue through the translucent outer layer of the overlay when the indicator is
illuminated from behind by the LED, which is soldered onto the instrument cluster electronic circuit
board. The high beam indicator is serviced as a unit with the instrument cluster.
The high beam indicator gives an indication to the vehicle operator whenever the headlamp high
beams are illuminated. This indicator is controlled by a transistor on the instrument cluster circuit
board based upon cluster programming and a hard wired multiplex input received by the cluster
from the headlamp beam select switch circuitry of the multi-function switch on the washer/beam
select switch mux circuit.
The high beam indicator Light Emitting Diode (LED) is completely controlled by the instrument
cluster logic circuit, and that logic will allow this indicator to operate whenever the instrument
cluster receives a battery current input on the fused B(+) circuit. Therefore, the LED can be
illuminated regardless of the ignition switch position. The LED only illuminates when it is provided a
path to ground by the instrument cluster transistor. The instrument cluster will turn on the high
beam indicator for the following reasons:
High Beam Headlamps-On Input - Each time the cluster detects a high beam headlamps-on input
from the headlamp beam select switch circuitry of the multi-function switch on the washer/beam
select switch mux circuit, the headlamp high beams and the high beam indicator will be illuminated.
The headlamp high beams and the high beam indicator remain illuminated until the cluster receives
a high beam headlamps-off input from the multi-function switch, or until the exterior lamp load
shedding (battery saver) timed interval expires, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the high beam indicator will
be turned on, then off again during the bulb check portion of the test to confirm the functionality of
the LED and the cluster control circuitry.
The instrument cluster continually monitors the headlamp switch and the multi-function switch to
determine the proper headlamp low beam and high beam control. The instrument cluster then
sends the proper low beam and high beam lamp-on and lamp-off messages to the Front Control
Module (FCM) over the Programmable Communications Interface (PCI) data bus and turns the
high beam indicator on or off accordingly. For further diagnosis of the high beam indicator or the
instrument cluster circuitry that controls the indicator, refer to testing.
For proper diagnosis of the headlamps, or the headlamp switch and multi-function switch inputs to
the instrument cluster that control the high beam indicator, a diagnostic scan tool is required.

Dodge Workshop Manuals > Lighting and Horns > Lamp Out Indicator > Component Information > Description and
Operation
Lamp Out Indicator: Description and Operation
A lamp out indicator is standard equipment on all instrument clusters. The lamp out indicator
consists of the words "LAMP OUT", which appear in the lower portion of the odometer/trip
odometer Vacuum-Fluorescent Display (VFD) unit.
The odometer/trip odometer VFD unit is soldered onto the cluster electronic circuit board and is
visible through a window with a smoked clear lens located on the lower edge of the tachometer
gauge dial face of the cluster overlay. The dark lens over the VFD prevents the lamp out indicator
from being clearly visible when it is not illuminated. The words "LAMP OUT" appear in an amber
color and at the same lighting level as the odometer/trip odometer information when they are
illuminated by the instrument cluster electronic circuit board. The lamp out indicator is serviced as a
unit with the VFD in the instrument cluster.
The lamp out indicator gives an indication to the vehicle operator when an exterior lamp has failed.
This indicator is controlled by the instrument cluster circuit board based upon cluster programming
and electronic messages received by the cluster from the Front Control Module (FCM) over the
Programmable Communications Interface (PCI) data bus.
The lamp out indicator is completely controlled by the instrument cluster logic circuit, and that logic
will only allow this indicator to operate when the instrument cluster receives a battery current input
on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the lamp
out indicator for the following reasons:
- Lamp Out Indicator Lamp-On Message - Each time the cluster receives a lamp out indicator
lamp-on message from the FCM indicating that an inoperative headlamp (low or high beam), turn
signal lamp, or brake lamp (excluding Center High Mounted Stop Lamp [CHMSL]) circuit has been
detected with the ignition switch in the On position, the lamp out indicator is illuminated solid. The
indicator remains illuminated until the cluster receives a lamp out indicator lamp-off message from
the FCM or until the ignition switch is turned to the Off position, whichever occurs first. If the
lamp-on message is received when the ignition is first turned to the On position, the lamp out
indicator is flashed at a fast rate (1 Hertz) for about thirty seconds before illuminating solid.
- Actuator Test - Each time the cluster is put through the actuator test, the lamp out indicator will be
turned on, then off again during the VFD portion of the test to confirm the functionality of the VFD
and the cluster control circuitry.
The FCM monitors each of the headlamp, turn signal lamp, and brake lamp (except CHMSL)
circuits to determine the condition of these exterior lamps. The FCM then sends the proper lamp
out indicator lamp-on and lamp-off messages to the instrument cluster. For further diagnosis of the
lamp out indicator or the instrument cluster circuitry that controls the indicator, refer to testing.
For proper diagnosis of the exterior lighting system circuits, the FCM, the PCI data bus, or the
electronic message inputs to the instrument cluster that control the lamp out indicator, a diagnostic
scan tool is required.

Parking Lamp Relay: Description and Operation
The park lamp relay is a conventional International Standards Organization (ISO) micro relay.
Relays conforming to the ISO specifications have common physical dimensions, current capacities,
terminal patterns, and terminal functions. This relay is contained within a small, rectangular,
molded plastic housing and is connected to all of the required inputs and outputs through five
integral male spade-type terminals that extend from the relay base plate.
The park lamp relay is located in the Power Distribution Center (PDC) in the engine compartment
near the battery Refer to the layout label on the underside of the PDC cover for specific relay cavity
assignment information. The park lamp relay cannot be adjusted or repaired and, if faulty or
damaged, the unit must be replaced.
The park lamp relay is an electromechanical switch that uses a low current input from the Front
Control Module (FCM) (also referred to as the Integrated Power Module/IPM) to control a high
current output to the park lamps. Within the relay are an electromagnetic coil, a movable contact
and two fixed contact points. A resistor is connected in parallel with the coil, and helps to dissipate
voltage spikes and electromagnetic interference that can be generated as the field of the relay coil
collapses.
The movable common supply contact point is held against the fixed normally closed contact point
by spring pressure. When the relay coil is energized, an electromagnetic field is produced by the
coil windings. This field draws the movable contact point away from the normally closed contact,
and holds it against the normally open contact. When the relay coil is de-energized, spring
pressure returns the movable contact back against the normally closed contact.
The inputs and outputs of the park lamp relay include:
- Common Supply Terminal (30) - The common feed terminal is connected to a fused B(+) circuit at
all times.
- Coil Ground Terminal (85) - The coil ground terminal is connected to a fused B(+) circuit at all
times.
- Coil Battery Terminal (86) - The coil battery terminal is connected to a control output of the FCM
through a park lamp relay control circuit. The FCM controls park lamp operation by controlling a
ground path through this circuit.
- Normally Open Terminal (87) - The normally open terminal is connected to the park lamps
through a park lamp relay output circuit and provides battery voltage to the park lamps whenever
the relay is energized.
- Normally Closed Terminal (87A) - The normally closed terminal is not connected to any circuit in
this application, but will have battery voltage present whenever the relay is de-energized.
The park lamp relay can be diagnosed using conventional diagnostic tools and methods.

How to Find Wiring Diagrams
Diagrams are presented in three main categories:
^ Power Distribution Diagrams
Circuits feeding/protecting the system diagrams
^ System Diagrams
Component Circuits that work together as a system
^ Grounds Diagrams
Circuits grounding the system diagrams
Power Distribution Diagrams
The power distribution diagrams are located at Power and Ground Distribution.

Dodge Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Backup Lamp Switch >
Component Information > Diagrams > Diagram Information and Instructions > Page 8175
These diagrams are especially useful for identifying potential suspects that could be causing any
"dead/unpowered" fuses and/or for identifying potential suspects that could be the causing any
"blown" fuses.
System Diagrams
These diagrams are useful for identifying a component's power source and its direct relationship to
the other components in the same system. These diagrams may also indicate a component's
indirect relationship with components in other systems.
Grounds Diagrams
The grounds diagrams are located at Power and Ground Distribution.
These diagrams are useful for determining the interconnections of the grounding circuits of different
systems.
PLEASE NOTE: When locating diagrams by their ID numbers, some diagram sheets may appear
to be missing because of gaps in the number sequences. These "gaps" are actually for diagrams
that do not apply to the vehicle model selected.
How to Navigate Between Wiring Diagrams
Circuits that go from one diagram sheet to another will be marked with references indicating which
diagram sheet the circuit went to/came from, i.e. "8W-16-4".
Theses references will be in the form of unique diagram identification numbers (i.e. 8W-16-4,
8W-25-2, etc). All diagram sheets are identified with this unique ID number in their captions.
Diagrams sheets being referred to that may reside outside of the set of diagrams you are viewing
can be accessed by clicking on the hyperlink for "Diagrams By Number" which is provided with all
sets of diagrams.

DIAGRAM LAYOUT
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
sheet, and the ground (B-) side of the circuit is placed near the bottom of the sheet (Fig. 1).

Component Information > Diagrams > Diagram Information and Instructions > Page 8178
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the sheet where the
component is shown complete. To find any diagram sheets referred to by number only, go to
Vehicle/Diagrams/Electrical/Diagrams By Number.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a
long one. In addition, switches and other components are shown as simply as possible, with regard
to function only.
The wiring diagrams are grouped into individual sets at the applicable system level. If a component
is most likely found in a particular system, it will be shown complete (all wires, connectors, and
pins) within that system's diagrams. It can, however, be shown partially in another system's
diagrams if it contains some associated wiring.

Backup Lamp Switch: Diagnostic Aids
Electrostatic Discharge (ESD) Sensitive Devices
Fig.6 Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol, comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items.
- Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation.

other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about six to eight inches apart and watch the voltmeter/test lamp. 4. If the voltmeter registers
voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary
These tools are listed and explained below.
- Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
- Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.
- Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance in
a circuit means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

- Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the
proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use
the other end of the tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem area. 6. Verify the proper operation. For this
step, check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams.

Backup Lamp Switch: Description and Operation
Vehicles equipped with a manual transmission have a normally open, spring-loaded plunger type
backup lamp switch (2). Vehicles with an optional electronic automatic transmission have a
Transmission Range Sensor (TRS) that is used to perform several functions, including that of the
backup lamp switch. The Transmission Range Sensor (TRS) is part of the solenoid module, which
is mounted to the top of the valve body inside the automatic transmission.
The backup lamp switch is located in a threaded hole on the side of the manual transmission
housing. The switch has a threaded body and a hex formation near the plunger end of the switch.
An integral connector receptacle at the end of the switch opposite the plunger connects the switch
to the vehicle electrical system through a take out and connector of the engine wire harness. When
installed, only the switch connector and the hex formation are visible on the outside of the
transmission housing. The backup lamp switch cannot be adjusted or repaired and, if faulty or
damaged, the entire switch unit must be replaced.
The backup lamp switch controls the flow of battery voltage to the backup lamp bulbs through an
output on the backup lamp feed circuit. The switch plunger is mechanically actuated by the
gearshift mechanism within the transmission, which will depress the switch plunger and close the
switch contacts whenever the reverse gear has been selected. The switch receives battery voltage
through a fuse in the Integrated Power Module (IPM) on a fused ignition switch output (run) circuit
whenever the ignition switch is in the On position. The backup lamp switch and circuits can be
tested using conventional diagnostic tools and methods.

Brake Light Switch: Description and Operation
The brake lamp switch (2) is a three circuit, spring-loaded plunger actuated switch that is secured
to the steering column support bracket under the instrument panel on the driver side of the vehicle.
The molded plastic switch housing has an integral connector receptacle (1) containing six terminal
pins and featuring a Connector Position Assurance (CPA) lock. The switch is connected to the
vehicle electrical system through a dedicated take out of the instrument panel wire harness.
The switch plunger (3) extends through a mounting collar (4) on one end of the switch housing. The
plunger has a one time telescoping self-adjustment feature that is activated after the switch is
installed by moving an adjustment release lever (5) on the opposite end of the switch housing
clockwise, until it locks into a position that is horizontal and parallel to the connector receptacle.
An installed brake lamp switch cannot be readjusted or repaired. If the switch is damaged, faulty, or
removed from its mounting position for any reason, it must be replaced with a new unit.
The brake lamp switch controls three independent circuits. These circuits are described as follows:
- Brake Lamp Switch Circuit - A normally open brake lamp switch circuit receives a battery voltage
input, and supplies this battery voltage to the brake lamps and the Controller Antilock Brake (CAB)
on a brake lamp switch output circuit only when the brake pedal is depressed (brake lamp switch
plunger released).
- Brake Lamp Switch Signal Circuit - A normally closed brake lamp switch signal circuit receives a
direct path to ground, and supplies this ground input to the Power-train Control Module (PCM) on a
brake lamp switch sense circuit only when the brake pedal is released (brake lamp switch plunger
is depressed).
- Speed Control Circuit - A normally closed speed control circuit receives a battery voltage input
from the Powertrain Control Module on a speed control supply circuit, and supplies this battery
voltage to the speed control servo solenoids (dump, vacuum, and vent) on a speed control brake
switch output circuit only when the speed control system is turned On and the brake pedal is
released (brake lamp switch plunger is depressed).
The components of the self-adjusting brake switch plunger consist of a two-piece telescoping
plunger, a split plunger locking collar, and a release wedge. The release lever has a shaft with a
wedge that spreads the plunger locking collar to an open or released position. After the switch is
installed and the brake pedal is released, the plunger telescopes to the correct adjustment position.
When the release lever is moved to the release position, the wedge is disengaged from the locking
collar causing the collar to apply a clamping pressure to the two plunger halves, fixing the plunger
length.
The brake lamp switch is diagnosed using conventional diagnostic tools and methods.

Combination Switch: Description and Operation
MULTIFUNCTION SWITCH
The multi-function switch (3) is located on the steering column, just below the steering wheel. The
only visible components of the multi-function switch are the control stalk (2) and control knob (1)
that extend through the steering column shrouds on the left side of the column, and the hazard
warning push button (4) that extends through the shroud on the top of the column. The remainder
of the switch including its mounting provisions, its electrical connection, and the turn signal cancel
actuator (5) are concealed beneath the shrouds.
The switch housing and controls are constructed of molded black plastic. Each of the switch
controls has white International Control and Display Symbol graphics applied to it, which clearly
identify its many functions. Three integral locating posts on the switch housing, one on the top and
two on the bottom, slide into channels in a receptacle on the left side of the multi-function switch
mounting housing near the top of the steering column to ensure proper positioning of the switch.
Then two screws secure the switch to the mounting housing. A single integral connector receptacle
containing four terminal pins on the back of the switch housing connects the switch to the vehicle
electrical system through a dedicated take out and connector of the instrument panel wire harness.
The multi-function switch provides the vehicle operator with a control interface for the following
functions:
- Hazard Warning Control - The multi-function switch hazard warning push button provides two
detent positions (On and Off) to control the hazard warning lamps.
- Headlamp Beam Selection - The multi-function switch control stalk provides detent switching for
selection of the headlamp high or low beams. There is also an intermediate momentary position
that allows the headlamp high beam circuits to be momentarily flashed to provide an optical horn
feature (sometimes referred to as flash-to-pass) as an optical signalling device.
- Turn Signal Control - The multi-function switch control stalk provides momentary non-detent (lane
change) switching or detent switching with automatic cancellation for both the left and right turn
signal lamps.
- Washer Control - The multi-function switch control knob provides a momentary position for
washer system operation.
- Wiper Control - The multi-function switch control knob provides two continuous wipe switch
positions, low speed or high speed; and, an intermittent wipe mode with five delay interval
positions.
The multi-function switch cannot be adjusted or repaired. If any function of the switch is faulty, or if
the switch is damaged, the entire switch must be replaced as a unit.
The multi-function switch uses resistor multiplexing to control the many functions and features it
provides using only three hard wired output circuits. The switch receives a clean ground from the
ElectroMechanical Instrument Cluster (EMIC) (also sometimes referred to as the Cab Control
Node/CCN) on a multi-function switch return circuit. It then provides outputs to the EMIC on a
wash/beam select switch signal circuit to control washer and headlamp beam selection, on an
intermittent wiper switch signal circuit to control wipers, and on a turn lamps switch signal circuit to
control turn signal and hazard warning functions.
The multi-function switch operates as follows:
- Hazard Warning Control - The hazard warning push button of the multi-function switch is
depressed to activate the hazard warning system, and depressed again to turn the system Off.
When the push button is actuated, the multi-function switch provides an output to the EMIC, and
the EMIC responds by sending electronic hazard switch status messages to the FCM over the PCI
data bus. The FCM then energizes and flashes or de-energizes both the left and right turn signal
circuits to provide the visual hazard warning.
- Headlamp Beam Selection - The control stalk of the multi-function switch is pulled towards the
steering wheel past a detent to actuate the integral beam select switch circuitry, or to an
intermediate, momentary position before the detent to actuate the optical horn feature. Each time
the control stalk is actuated to a detent position, the opposite headlamp beam from what is
currently selected will be energized. Each time the control stalk is actuated to the momentary
position with the headlamps turned off, the headlamp high beams will be illuminated for as long as
the control stalk is held in this position. The multi-function switch provides an output to the EMIC,
and the EMIC responds by sending electronic beam select switch status messages to the FCM
over the PCI data bus. The FCM energizes or de-energizes the selected low or high beam circuits.
- Turn Signal Control - The control stalk of the multi-function switch is moved upward to activate the
right turn signal circuitry, and, downward to activate the left turn signal circuitry. The turn signal
switch has a detent position in each direction that provides turn signals with automatic cancellation,
and an intermediate, momentary position in each direction that provides turn signals only until the
control stalk is released. When the control stalk is moved to a detent turn signal switch position, the
cancel actuator extends toward the center of the steering column. A turn signal

Component Information > Locations > Page 8213
cancel cam that is integral to the clockspring rotates with the steering wheel and the cam lobes
contact the cancel actuator when it is extended from the multi-function switch. When the steering
wheel is rotated during a turning maneuver, one of the two turn signal cancel cam lobes will contact
the turn signal cancel actuator. The cancel actuator latches against the cancel cam rotation in the
direction opposite that which is signaled. If the left turn signal detent is selected, the lobes of the
cancel cam will ratchet past the cancel actuator when the steering wheel is rotated to the left, but
will unlatch the cancel actuator as the steering wheel rotates to the right and returns to center,
which will cancel the turn signal event and release the control stalk from the detent so it returns to
the neutral Off position. When a turn signal is activated, the multifunction switch provides an output
to the EMIC, and the EMIC responds by sending electronic turn signal switch status messages to
the FCM over the PCI data bus. The FCM energizes and flashes or de-energizes the selected left
or right turn signal circuits.
- Washer Control - The control knob on the end of the multi-function switch control stalk is
depressed towards the steering column to momentarily activate the washer pump in the washer
mode. The washer pump will continue to operate in the washer mode until the control knob is
released. The multi-function switch provides an output to the EMIC, and the EMIC responds by
sending electronic washer switch status messages to the Front Control Module (FCM) over the
Programmable Communications Interface (PCI) data bus. The FCM responds by energizing or
de-energizing the washer pump in the washer mode.
- Wiper Control - The control knob on the end of the multi-function switch control stalk is rotated to
one of the continuous wiper detents, to one of five intermittent wiper detents, or to the Off position
to select the wiper mode. The multi-function switch provides an output to the EMIC, and the EMIC
responds by sending electronic wiper switch status messages to the FCM over the PCI data bus.
The FCM responds by energizing or de-energizing the wiper on/off and high/low relays in the
Power Distribution Center (PDC) for wiper system control.
The multi-function switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the multiplexed inputs to the EMIC requires the use of a diagnostic scan
tool.

Dodge Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Door Switch > Component
Information > Description and Operation
Door Switch: Description and Operation
This vehicle has up to four door ajar switches, one for each door. Each switch is concealed within
and integral to its respective door latch unit. The switches are momentary leaf contact-type units
that are actuated by the mechanisms internal to the door latch. A short pigtail wire and connector
on each door latch connects the door ajar switch to the vehicle electrical system through its
respective door wire harness. The door ajar switches cannot be adjusted or repaired and, if faulty
or damaged, the door latch unit must be replaced.
The door ajar switches are actuated by the mechanisms internal to the door latch. When a door is
closed and properly latched, its door ajar switch is an open circuit. When a door is open or only
partially latched, the door ajar switch is a closed circuit. The door ajar switches are hard wired in
series between a body ground and the Electro-Mechanical Instrument Cluster (EMIC). The EMIC
reads the hard wired door ajar switch inputs through internal pull-ups, then uses these inputs to
control many electronic functions and features of the vehicle.
The EMIC also sends the proper switch status messages to other electronic modules over the
Programmable Communications Interface (PCI) data bus network. The door ajar switches can be
diagnosed and tested using conventional diagnostic tools and methods. However, conventional
diagnostic methods may not prove conclusive in the diagnosis of the EMIC, the PCI data bus, or
the electronic messaging used to convey door ajar switch status to other modules in the vehicle.
The most reliable, efficient, and accurate means to diagnose the EMIC, the PCI data bus, and both
the hard wired and electronic message inputs and outputs affected by the door ajar switch inputs
requires the use of a diagnostic scan tool.

Headlamp Switch: Description and Operation
The headlamp switch (1) is located on the instrument panel, to the left of the steering column. Two
different switches are used. The standard switch features a three-position rotary knob (3) for
exterior lighting control and a thumbwheel (2) for panel lamps dimming and interior lighting control.
An optional switch has the same thumbwheel, but has an additional "Pull" function added to the
rotary knob for selecting the optional front fog lamps.
Each of these switches is constructed of molded plastic. The rotary knob is molded plastic and has
a raised center lever to ease operator control. The thumbwheel is also plastic and knurled. The
optional front fog lamp rotary knob is plastic with a smooth finish and an International Control and
Display Symbol icon for "Front Fog Light" applied to it. The switch face plate is also labeled with
graphics and icons to clearly identify the many functions of the rotary knob and thumbwheel.
Three screws secure the switch to the back of the cluster bezel through integral mounting flanges
that are molded to each side of the switch housing. The back of the switch housing has an integral
connector receptacle containing terminal pins that connect the switch to the vehicle electrical
system through a dedicated take out and connector of the instrument panel wire harness. A panel
dimmer controlled incandescent bulb soldered to the circuit board within the switch provides back
lighting for visibility at night, but is not serviceable. The headlamp switch cannot be repaired and, if
faulty or damaged, it must be replaced.
The headlamp switch uses two resistor multiplexed outputs to control the many functions and
features it provides. The switch receives a clean ground from the ElectroMechanical Instrument
Cluster (EMIC) (also sometimes referred to as the Cab Control Node/CCN) on a headlamp switch
return circuit. It then provides outputs to the EMIC on a headlamp switch signal circuit to control
exterior lighting functions, and on a panel lamps dimmer signal circuit to control panel dimmer and
interior lighting functions.
The switch illumination circuit receives a path to ground at all times through the left instrument
panel ground circuit. The illumination level is controlled by a Pulse-Width Modulated (PWM) output
received from the EMIC on a headlamp switch illumination control circuit. The EMIC controls this
output based upon the dimmer signal select mux input from the headlamp switch.
- Front Fog Lamps Control - For vehicles so equipped, the rotary knob on the headlamp switch is
pulled out to activate or pushed in to deactivate the optional front fog lamps. The headlamp switch
provides an output to the EMIC, and the EMIC responds by sending electronic fog lamp switch
status messages to the Front Control Module (FCM) over the Programmable Communications
Interface (PCI) data bus. The FCM responds by energizing or de-energizing the front fog lamp
relay in the Power Distribution Center (PDC).
- Exterior Lighting Control - The rotary knob on the headlamp switch is rotated to a detent position
to activate or deactivate the exterior lighting. The headlamp switch provides an output to the EMIC,
and the EMIC responds by sending electronic exterior lighting switch status messages to the FCM
over the PCI data bus. The FCM responds by energizing or de-energizing the park lamp relay in
the PDC and the high or low beam headlamp circuits. The FCM remembers which headlamp
beams were last selected using the multi-function switch, and energizes those beams by default
the next time the headlamps are turned On.
- Interior Lighting Control - The thumbwheel on the headlamp switch is rotated to the dome defeat,
dome on, parade/funeral mode, or one of the six panel dimmer detent positions to control the
interior courtesy/dome and panel lamps. The headlamp switch provides an output to the EMIC, and
the EMIC responds by providing the appropriate interior lighting control outputs through its internal
courtesy lamp driver circuits, electronic dimming level messages to other modules over the PCI
data bus, and/or the proper PWM outputs to control dimming levels through several panel dimmer
illumination control driver circuits.
The headlamp switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the multiplexed inputs to and PWM processing of the EMIC requires the
use of a diagnostic scan tool.

In addition to the trailer tow wiring provisions, all vehicles include right and left trailer tow stop/turn
relays installed in the PDC. When the FCM receives the appropriate inputs for normal turn signal,
hazard warning or brake lamp operation, it responds by also energizing or de-energizing these
trailer tow relays. When a trailer tow relay is energized, it provides battery voltage from a fused
B(+) fuse to the trailer lamps through the trailer tow wiring to synchronize the illumination and flash
rate of the trailer brake and turn signal lamps with those of the tow vehicle.

The rear body wire harness on the rear frame (1) of all vehicles is equipped with a take out with a
standard, light-duty 4-pin trailer tow connector (2) that is secured to the top of the trailer hitch
platform (4) behind the rear bumper. Vehicles equipped with an optional factory-installed trailer
towing package have a second take out with a connector (3) that plugs into a receptacle in the
back of a heavy duty, sealed, 7-pin trailer tow connector that is located near the center of the rear
bumper.
Vehicles equipped with the trailer tow package also include an electric trailer brake wiring provision
that terminates at a connector located on top of the large body harness connection under the
instrument panel to the left of the brake pedal, as well as an electric trailer brake pigtail harness
and an instruction card (1) that are stored in the glove box (2) when the vehicle is shipped from the
factory.
The wiring information includes wiring diagrams, proper wire and connector repair procedures,
further details on wire harness routing and retention, as well as pin-out and location views for the
various wire harness connectors, splices and grounds.
The standard 4-pin trailer tow connector contains the following vehicle circuits: park/tail lamps, left
stop/turn lamp, right stop/turn lamp, and ground. The optional trailer towing package 7-way
connector contains the same circuits as the 4-pin connector plus the following additional circuits:
backup lamp, trailer battery and electric brake.
If an aftermarket electric brake controller is used, the electric brake pigtail harness supplied will
make installation easier. The connection (blue 4-way connector) for the harness is located under
the instrument panel to the left of the brake pedal on top of the large body harness connection.
The battery line of this harness may be used to charge the trailer battery. However, a battery

Combination Switch: Description and Operation
MULTIFUNCTION SWITCH
The multi-function switch (3) is located on the steering column, just below the steering wheel. The
only visible components of the multi-function switch are the control stalk (2) and control knob (1)
that extend through the steering column shrouds on the left side of the column, and the hazard
warning push button (4) that extends through the shroud on the top of the column. The remainder
of the switch including its mounting provisions, its electrical connection, and the turn signal cancel
actuator (5) are concealed beneath the shrouds.
The switch housing and controls are constructed of molded black plastic. Each of the switch
controls has white International Control and Display Symbol graphics applied to it, which clearly
identify its many functions. Three integral locating posts on the switch housing, one on the top and
two on the bottom, slide into channels in a receptacle on the left side of the multi-function switch
mounting housing near the top of the steering column to ensure proper positioning of the switch.
Then two screws secure the switch to the mounting housing. A single integral connector receptacle
containing four terminal pins on the back of the switch housing connects the switch to the vehicle
electrical system through a dedicated take out and connector of the instrument panel wire harness.
The multi-function switch provides the vehicle operator with a control interface for the following
functions:
- Hazard Warning Control - The multi-function switch hazard warning push button provides two
detent positions (On and Off) to control the hazard warning lamps.
- Headlamp Beam Selection - The multi-function switch control stalk provides detent switching for
selection of the headlamp high or low beams. There is also an intermediate momentary position
that allows the headlamp high beam circuits to be momentarily flashed to provide an optical horn
feature (sometimes referred to as flash-to-pass) as an optical signalling device.
- Turn Signal Control - The multi-function switch control stalk provides momentary non-detent (lane
change) switching or detent switching with automatic cancellation for both the left and right turn
signal lamps.
- Washer Control - The multi-function switch control knob provides a momentary position for
washer system operation.
- Wiper Control - The multi-function switch control knob provides two continuous wipe switch
positions, low speed or high speed; and, an intermittent wipe mode with five delay interval
positions.
The multi-function switch cannot be adjusted or repaired. If any function of the switch is faulty, or if
the switch is damaged, the entire switch must be replaced as a unit.
The multi-function switch uses resistor multiplexing to control the many functions and features it
provides using only three hard wired output circuits. The switch receives a clean ground from the
ElectroMechanical Instrument Cluster (EMIC) (also sometimes referred to as the Cab Control
Node/CCN) on a multi-function switch return circuit. It then provides outputs to the EMIC on a
wash/beam select switch signal circuit to control washer and headlamp beam selection, on an
intermittent wiper switch signal circuit to control wipers, and on a turn lamps switch signal circuit to
control turn signal and hazard warning functions.
The multi-function switch operates as follows:
- Hazard Warning Control - The hazard warning push button of the multi-function switch is
depressed to activate the hazard warning system, and depressed again to turn the system Off.
When the push button is actuated, the multi-function switch provides an output to the EMIC, and
the EMIC responds by sending electronic hazard switch status messages to the FCM over the PCI
data bus. The FCM then energizes and flashes or de-energizes both the left and right turn signal
circuits to provide the visual hazard warning.
- Headlamp Beam Selection - The control stalk of the multi-function switch is pulled towards the
steering wheel past a detent to actuate the integral beam select switch circuitry, or to an
intermediate, momentary position before the detent to actuate the optical horn feature. Each time
the control stalk is actuated to a detent position, the opposite headlamp beam from what is
currently selected will be energized. Each time the control stalk is actuated to the momentary
position with the headlamps turned off, the headlamp high beams will be illuminated for as long as
the control stalk is held in this position. The multi-function switch provides an output to the EMIC,
and the EMIC responds by sending electronic beam select switch status messages to the FCM
over the PCI data bus. The FCM energizes or de-energizes the selected low or high beam circuits.
- Turn Signal Control - The control stalk of the multi-function switch is moved upward to activate the
right turn signal circuitry, and, downward to activate the left turn signal circuitry. The turn signal
switch has a detent position in each direction that provides turn signals with automatic cancellation,
and an intermediate, momentary position in each direction that provides turn signals only until the
control stalk is released. When the control stalk is moved to a detent turn signal switch position, the
cancel actuator extends toward the center of the steering column. A turn signal
Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Combination Switch > Component Information >

cancel cam that is integral to the clockspring rotates with the steering wheel and the cam lobes
contact the cancel actuator when it is extended from the multi-function switch. When the steering
wheel is rotated during a turning maneuver, one of the two turn signal cancel cam lobes will contact
the turn signal cancel actuator. The cancel actuator latches against the cancel cam rotation in the
direction opposite that which is signaled. If the left turn signal detent is selected, the lobes of the
cancel cam will ratchet past the cancel actuator when the steering wheel is rotated to the left, but
will unlatch the cancel actuator as the steering wheel rotates to the right and returns to center,
which will cancel the turn signal event and release the control stalk from the detent so it returns to
the neutral Off position. When a turn signal is activated, the multifunction switch provides an output
to the EMIC, and the EMIC responds by sending electronic turn signal switch status messages to
the FCM over the PCI data bus. The FCM energizes and flashes or de-energizes the selected left
or right turn signal circuits.
- Washer Control - The control knob on the end of the multi-function switch control stalk is
depressed towards the steering column to momentarily activate the washer pump in the washer
mode. The washer pump will continue to operate in the washer mode until the control knob is
released. The multi-function switch provides an output to the EMIC, and the EMIC responds by
sending electronic washer switch status messages to the Front Control Module (FCM) over the
Programmable Communications Interface (PCI) data bus. The FCM responds by energizing or
de-energizing the washer pump in the washer mode.
- Wiper Control - The control knob on the end of the multi-function switch control stalk is rotated to
one of the continuous wiper detents, to one of five intermittent wiper detents, or to the Off position
to select the wiper mode. The multi-function switch provides an output to the EMIC, and the EMIC
responds by sending electronic wiper switch status messages to the FCM over the PCI data bus.
The FCM responds by energizing or de-energizing the wiper on/off and high/low relays in the
Power Distribution Center (PDC) for wiper system control.
The multi-function switch can be diagnosed using conventional diagnostic tools and methods.
However, proper testing of the multiplexed inputs to the EMIC requires the use of a diagnostic scan
tool.

Description and Operation
Turn Signal Cancel Cam: Description and Operation
The turn signal cancel cam (3) is concealed within the steering column. The turn signal cancel cam
consists of two lobes on a molded plastic ring that is snapped into the lower hub of the clockspring
rotor. The clock-spring mechanism provides turn signal cancellation as well as a constant electrical
connection between the horn switch, driver airbag, speed control switches, and remote radio
switches on the steering wheel and the instrument panel wire harness on the steering column. The
housing of the clockspring (2) is secured to the multi-function switch mounting housing on the
steering column and remains stationary. The rotor of the clock-spring, including the turn signal
cancel cam lobes rotate with the steering wheel.
The turn signal cancel cam is serviced as a unit with the clockspring and cannot be repaired. If
faulty or damaged, the entire clockspring unit must be replaced. When the multi-function switch
control stalk is moved to a latched turn signal position, a turn signal cancel actuator is extended
from the inside surface of the switch housing toward the turn signal cancel cam. As the steering
wheel is rotated to complete the turn, one of the two cam lobes will contact the actuator,
automatically cancelling the turn signal event and releasing the latched multi-function switch control
stalk to the neutral position.

Description and Operation
Turn Signal Indicator: Description and Operation
Two turn signal indicators, one right and one left, are standard equipment on all instrument
clusters. The turn signal indicators are located near the upper edge of the instrument cluster,
between the speedometer and the tachometer.
Each turn signal indicator consists of a stencil-like cutout of the International Control and Display
Symbol icon for "Turn Warning" in the opaque layer of the instrument cluster overlay. The dark
outer layer of the overlay prevents these icons from being clearly visible when they are not
illuminated. A green Light Emitting Diode (LED) behind each cutout in the opaque layer of the
overlay causes the icon to appear in green through the translucent outer layer of the overlay when
the indicator is illuminated from behind by the LED, which is soldered onto the instrument cluster
electronic circuit board. The turn signal indicators are serviced as a unit with the instrument cluster.
The turn signal indicators give an indication to the vehicle operator that the turn signal (left or right
indicator flashing) or hazard warning (both left and right indicators flashing) have been selected
and are operating. These indicators are controlled by transistors on the instrument cluster
electronic circuit board based upon the cluster programming, a hard wired multiplex input received
by the cluster from the turn signal and hazard warning switch circuitry of the multi-function switch
on the turn/hazard switch mux circuit, and electronic messages received from the Front Control
Module (FCM) (also known as the Integrated Power Module/IPM) over the Programmable
Communications Interface (PCI) data bus.
Each turn signal indicator Light Emitting Diode (LED) is completely controlled by the instrument
cluster logic circuit, and that logic will allow this indicator to operate whenever the instrument
cluster receives a battery current input on the fused B(+) circuit. Therefore, each LED can be
illuminated regardless of the ignition switch position. The LED only illuminates when it is provided a
path to ground by the instrument cluster transistor. The instrument cluster will turn on the turn
signal indicators for the following reasons:
- Turn Signal-On Input - Each time the cluster detects a turn signal-on input from the turn signal
switch circuitry of the multi-function switch on the turn/hazard switch mux circuit, it sends the
appropriate electronic turn signal switch status messages to the FCM over the PCI data bus. The
FCM responds to these messages by controlling a battery voltage output and the flash rate for
either the right or left turn signal lamps. The FCM also sends the appropriate electronic messages
back to the EMIC to control the illumination and flash rate of the right or left turn signal indicators,
as well as to control the click rate of an electromechanical relay soldered onto the EMIC electronic
circuit board that emulates the sound emitted by a conventional turn signal flasher. The turn signals
and the turn signal indicators continue to flash on and off until the cluster receives a turn signal-off
input from the multi-function switch, or until the ignition switch is turned to the Off position,
whichever occurs first.
- Hazard Warning-On Input - Each time the cluster detects a hazard warning-on input from the
hazard warning switch circuitry of the multi-function switch on the turn/hazard switch mux circuit, it
sends the appropriate electronic hazard switch status messages to the FCM over the PCI data bus.
The FCM responds to these messages by controlling a battery voltage output and the flash rate for
each of the right and left turn signal lamps. The FCM also sends the appropriate electronic
messages back to the EMIC to control the illumination and flash rate of the right and left turn signal
indicators, as well as to control the click rate of an electromechanical relay soldered onto the EMIC
electronic circuit board that emulates the sound emitted by a conventional hazard warning flasher.
The turn signals and the turn signal indicators continue to flash on and off until the cluster receives
a hazard warning-off input from the multi-function switch.
- Lamp Out Mode - The instrument cluster also sends electronic turn signal on and off messages to
the FCM over the PCI data bus, and the FCM flashes the appropriate exterior turn signal lamps. If
the FCM detects an inoperative turn signal lamp or circuit, it increases the flash rate for the
remaining operative turn signals and sends an electronic message back to the instrument cluster.
The instrument cluster then increases the flash rate of the turn signal indicators) and the clicking
rate of the electromechanical relay to provide an indication of the problem to the vehicle operator.
- Actuator Test - Each time the cluster is put through the actuator test, the turn signal indicators will
be turned on, then off again during the bulb check portion of the test to confirm the functionality of
each LED and the cluster control circuitry.
The instrument cluster continually monitors the multi-function switch and electronic messages from
the FCM to determine the proper turn signal and hazard warning system control. For further
diagnosis of the turn signal indicators or the instrument cluster circuitry that controls the indicators,
refer to testing.
For proper diagnosis of the turn signal and hazard warning system, the multi-function switch, the
FCM, the PCI data bus, or the electronic message inputs to the instrument cluster that control the
turn signal indicators, a diagnostic scan tool is required.

Rear Defogger Relay: Description and Operation
The rear window defogger (EBL) relay (1) is a International Standards Organization (ISO)-type
relay. Relays conforming to the ISO specifications have common physical dimensions, current
capacities, terminal functions and patterns (2). The EBL relay is a electromechanical device that
switches battery current through a fuse in the integrated power module (IPM) to the rear window
defogger grid. The EBL relay is energized when the relay coil is provided a ground path by the
control circuitry within the A/C-heater control.
The EBL relay is located in the IPM in the engine compartment.
The ISO-standard rear window defogger (EBL) relay is an electromechanical switch that uses a low
current input controlled by the A/C-heater control to control the high current output to the rear
window defogger grid lines. The movable, common feed relay contact is held against the fixed,
normally closed relay contact by spring pressure. When the electromagnetic relay coil is energized,
it draws the movable common feed relay contact away from the fixed, normally closed relay contact
and, holds it against the fixed, normally open relay contact. This action allows high current to flow
to the rear window defogger grid lines.
When the relay coil is de-energized, spring pressure returns the movable relay contact back
against the fixed, normally closed contact point. The resistor or diode is connected in parallel with
the relay coil, and helps to dissipate voltage spikes and electromagnetic interference that can be
generated as the electromagnetic field of the relay coil collapses.
The EBL relay terminals are connected to the vehicle electrical system through a receptacle in the
integrated power module (IPM). The inputs and outputs of the EBL relay include:
- Terminal (30) receives battery current through a fuse in the IPM only when the EBL relay coil is
energized.
- Terminal (85) receives a ground through the EBL relay control circuit only when the A/C-heater
control electronically pulls the circuit to ground.
- Terminal (86) receives battery current through a fused ignition switch output circuit only when the
ignition switch is in the Run position.
- Terminal (87) provides battery current to the rear window defogger grid lines through the EBL
relay only when the EBL relay coil is energized.
- Terminal (87A) is not connected to any circuit in this application.
The EBL relay cannot be repaired and, if faulty or damaged, it must be replaced. Refer to the
appropriate wiring information for diagnosis and testing of the ISO-standard relay and for complete
rear window defogger (EBL) wiring diagrams.

Power Window Switch: Testing and Inspection
The Light-Emitting Diode (LED) illumination lamps for all of the power window and lock switch and
bezel unit switch paddles receive battery current through the power window circuit breaker in the
junction block. If all of the LEDs are inoperative in both the power window and lock switch units and
the power windows are inoperative, refer to testing. If the power windows operate, but any or all of
the LEDs are inoperative, the power window and lock switch units with the inoperative LED(s) is
faulty and must be replaced. For complete circuit diagrams,
1. Check the fuse in the Integrated Power Module (IPM) and the circuit breaker located near the
park brake pedal. If OK, go to Step 2. If not OK,
replace the faulty fuse or circuit breaker.
2. Turn the ignition switch to the On position. Check for battery voltage at the fuse in the Integrated
Power Module (IPM). If OK, turn the ignition
switch to the Off position and go to Step 3. If not OK, check circuit breaker and repair the circuit to
the ignition switch as required.
3. Disconnect and isolate the battery negative cable. Remove the power window switch unit from
the door trim panel (passenger doors). The drivers
door switch is included with the window/lock switch. Unplug the wire harness connector from the
switch unit.
Power Window Switch Continuity Chart
4. Test the power window switch continuity. See the Power Window Switch Continuity charts to
determine if the continuity is correct in the Off, Up
and Down switch positions. If OK, refer to testing. If not OK, replace the faulty switch.

Back Window Glass: Service and Repair Backlite
BACKLITE
REMOVAL
CAUTION: It is difficult to salvage the backlite during the removal operation. The backlite is part of
the structural support for the roof. The urethane bonding used to secure the glass to the fence is
difficult to cut or clean from any surface. Since the molding is set in urethane, it is unlikely it would
be salvaged. Before removing the backlite, check the availability from the parts supplier.
NOTE: The backlite is attached to the window frame with urethane adhesive. The urethane
adhesive is applied cold and seals the surface area between the window opening and the glass.
The primer adheres the urethane adhesive to the backlite.
1. Roll down door glass. 2. Remove headliner (9).
3. On standard cab models remove the upper b-pillar trim (5), Refer to Trim Panel.

NUMBER: 23-035-05
GROUP: Body
DATE: July 26, 2005
SUBJECT: Circular/Ring Marks On Glass
MODELS
DISCUSSION:
Circular patterns may appear on the glass which are visible mostly when the glass is moist or
fogged up. The size varies from 2-6 inches and are typically described as "rings" or "circles" that
won't clean off with standard glass cleaners.
To determine if this type of mark(s) is present use a clean, moist cloth lightly wet the surface of the
glass component. Carefully observe if these circular marks develop as the water from the cloth
dissipates. Repeat this process on both the inside and outside of the glass component (if
applicable) to identify which surface of glass (inside or outside) has the condition. If the marks are
present on the outside of glass, this condition will naturally lessen with sunlight exposure and time.
Customer concerns are mostly associated with this condition being present on the inside surface. If
the customer wants the marks removed, they can be removed using a non-abrasive cleanser or
polish. Appropriate materials are Calcium Carbonate (Bon Ami(R)) or a glass polish containing
Cerium Oxide.
CAUTION:
Do not use any materials containing quartz or silicate abrasives. Typical examples of abrasive
cleansers include (Ajax(R), Comet(R), Soft-Scrub(R), etc). Cleansers with abrasives will scratch
the glass surface and cause irreparable damage.

Windshield: Service Precautions
WARNING
WINDSHIELD SAFETY PRECAUTIONS
Do not operate the vehicle within 24 hours of windshield installation. It takes at least 24 hours for
urethane adhesive to cure. If it is not cured, the windshield may not perform properly in an
accident.
- Urethane adhesives are applied as a system. Use glass cleaner, glass prep solvent, glass primer,
PVC (vinyl) primer and pinch weld (fence) primer provided by the adhesive manufacturer. If not,
structural integrity could be compromised.
- DaimlerChrysler does not recommend glass adhesive by brand. Technicians should review
product labels and technical data sheets, and use only adhesives that their manufactures warranty
and will restore a vehicle to the requirements of fmvss 212. Technicians should also insure that
primers and cleaners are compatible with the particular adhesive used.
- Be sure to refer to the urethane manufacturer's directions for curing time specifications and do not
use adhesive after its expiration date.
- Vapors that are emitted from the urethane adhesive or primer could cause personal injury or
death. Use them in a well-ventilated area.
- Skin contact with urethane adhesive should be avoided. Personal injury or death may result.
- Always wear eye and hand protection when working with glass.
Protect all painted and trimmed surfaces from coming in contact with urethane or primers.
Be careful not to damage painted surfaces when removing moldings or cutting urethane around
windshield

Dodge Workshop Manuals > Wiper and Washer Systems > Check Valve, Washer > Component Information > Description
and Operation
Check Valve: Description and Operation
A single washer system check valve is standard equipment on this model, and is installed in the
washer system plumbing. The check valve is integral to the washer nozzle plumbing eye fitting (2)
located in the cowl plenum area beneath the cowl plenum cover/grille panel near the base of the
windshield. The check valve consists of a molded plastic body with a raised arrowhead (4) molded
into its center section that indicates the direction of the flow through the valve, and three barbed
hose nipples (1 and 3) formed in a eye configuration on the outside circumference of the center
section of the valve body. The check valve cannot be adjusted or repaired and, if faulty or
damaged, it must be replaced.
The check valve provides more than one function in this application. It serves as a eye connector
fitting between the engine compartment and washer nozzle sections of the washer supply hose. It
prevents washer fluid from draining out of the washer supply hoses back to the washer reservoir.
This drain-back would result in a lengthy delay from when the washer switch is actuated until
washer fluid was dispensed through the washer nozzles, because the washer pump would have to
refill the washer plumbing from the reservoir to the nozzles. Such a drain-back condition could also
result in water, dirt, or other outside contaminants being siphoned into the washer system through
the washer nozzle orifice. This water could subsequently freeze and plug the nozzle, while other
contaminants could interfere with proper nozzle operation and cause improper nozzle spray
patterns. In addition, the check valve prevents washer fluid from siphoning through the washer
nozzles after the washer system is turned Off.
When the washer pump pressurizes and pumps washer fluid from the reservoir through the washer
plumbing, the fluid pressure (5) unseats a diaphragm (3) from over a sump well within the valve by
overriding the pressure applied to a piston (2) by a spring (1). With the diaphragm unseated,
washer fluid is allowed to flow toward the two washer nozzles (4). When the washer pump stops
operating, the spring pressure on the piston seats the diaphragm over the sump well in the valve
and fluid flow in either direction within the washer plumbing is prevented. The check valve cannot
be adjusted or repaired and, if faulty or damaged, it must be replaced.

Wiper Relay: Description and Operation Wiper High/Low Relay
The wiper high/low relay is a conventional International Standards Organization (ISO) micro relay.
Relays conforming to the ISO specifications have common physical dimensions, current capacities,
terminal patterns, and terminal functions. This relay is contained within a small, rectangular,
molded plastic housing and is connected to all of the required inputs and outputs through five
integral male spade-type terminals that extend from the relay base plate.
The wiper high/low relay is located in the Power Distribution Center (PDC)/Integrated Power
Module (IPM) in the engine compartment near the battery. Refer to the layout label on the
underside of the PDC cover for specific relay cavity assignment information. The wiper high/low
relay cannot be adjusted or repaired and, if faulty or damaged, the unit must be replaced.
The wiper high/low relay is an electromechanical switch that uses a low current input from the Front
Control Module (FCM) to control a high current output to the wiper motor. The movable common
feed contact point is held against the fixed normally closed contact point by spring pressure. When
the relay coil is energized, an electromagnetic field is produced by the coil windings. This
electromagnetic field draws the movable relay contact point away from the fixed normally closed
contact point, and holds it against the fixed normally open contact point. When the relay coil is
de-energized, spring pressure returns the movable contact point back against the fixed normally
closed contact point. A resistor is connected in parallel with the relay coil in the relay, and helps to
dissipate voltage spikes and electromagnetic interference that can be generated as the
electromagnetic field of the relay coil collapses.
The wiper high/low relay terminals are connected to the vehicle electrical system through a
connector receptacle in the Power Distribution Center (PDC)/Integrated Power Module (IPM). The
inputs and outputs of the wiper high/low relay include:
- Common Feed Terminal - The common feed terminal (30) is connected to the output of the wiper
on/off relay at all times through the wiper on/off relay output circuit.
- Coil Ground Terminal - The coil ground terminal (85) is connected to a control output of the Front
Control Module (FCM) through a wiper high/low relay control circuit. The FCM controls wiper motor
operation by controlling a ground path through this circuit.
-
Coil Battery Terminal - The coil battery terminal (86) receives battery current when the ignition
switch is in the On or Accessory positions from a fuse in the PDC/IPM through a fused ignition
switch output (run-acc) circuit.
- Normally Open Terminal - The normally open terminal (87) is connected to the high speed brush
of the wiper motor through a wiper high/low relay high speed output circuit, and is connected to the
high speed brush whenever the relay is energized.
- Normally Closed Terminal - The normally closed terminal (87A) is connected to the low speed
brush of the wiper motor through a wiper high/low relay low speed output circuit, and is connected
to the low speed brush whenever the relay is de-energized.
The wiper high/low relay can be diagnosed using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the
ElectroMechanical Instrument Cluster (EMIC), the FCM, or the electronic message inputs to or
outputs from the EMIC and the FCM that control the operation of the wiper high/low relay. The
most reliable, efficient, and accurate means to diagnose the wiper high/low relay, the EMIC, the
FCM, or the electronic message inputs and outputs related to the wiper high/low relay operation
requires the use of a diagnostic scan tool.

Washer Fluid Level Switch: Description and Operation
The washer fluid level switch is a single pole, single throw reed-type switch mounted on the side of
the washer reservoir (4) in the engine compartment. Only the molded plastic switch mounting
flange (1) and the integral connector receptacle (8) are visible when the switch is installed in the
reservoir. A short nipple formation (2) extends from the inner surface of the switch mounting flange,
and a barb on the nipple is pressed through a rubber grommet seal (5) installed in the mounting
hole of the reservoir.
A small, molded plastic float (3) has two pivot pins (6) near its center that are snapped into two
receptacles near the ends of two stanchions that extend toward the float from the nipple formation.
A small magnet (7) is secured within the end of the float nearest the nipple, and a reed switch is
concealed within the nipple. A diagnostic resistor is connected between the two switch terminals
within the switch mounting flange. The washer fluid level switch cannot be adjusted or repaired. If
faulty or damaged, the switch must be replaced.
The washer fluid level switch uses a pivoting, oblong float to monitor the level of the washer fluid in
the washer reservoir. The float contains a small magnet. When the float pivots, the proximity of this
magnet to a stationary reed switch within the nipple formation of the switch changes. When the
fluid level in the washer reservoir is at or above the float level, the float moves to a vertical position,
the influence of the float magnetic field is removed from the reed switch, and the normally open
reed switch contacts open. When the fluid level in the washer reservoir falls below the level of the
pivoting float, the float moves to a horizontal position, the influence of the float magnetic field is
applied to the reed switch, and the contacts of the normally open reed switch close.
The washer fluid level switch is connected to the vehicle electrical system through a dedicated take
out and connector of the right (except SRT-10 and diesel engines) or left (SRT-10 and diesel
engines only) headlamp and dash wire harness. The switch is connected in series between a clean
ground output of the Front Control Module (FCM) on a sensor return circuit and the washer fluid
switch sense input to the FCM. When the switch closes, the FCM senses the ground on the washer
fluid switch sense circuit. The FCM is programmed to respond to this input by sending an electronic
washer fluid indicator lamp-on message to the instrument cluster over the Programmable
Communications Interface (PCI) data bus. The instrument cluster responds to this message by
illuminating the washer fluid indicator and by sounding an audible chime tone warning.
The washer fluid level switch may be diagnosed and tested using conventional diagnostic tools and
procedures. However, conventional diagnostic methods may not prove conclusive in the diagnosis
of the instrument cluster, the FCM, or the electronic message inputs to or outputs from the
instrument cluster and the FCM that control the operation of the washer fluid visual and/or audible
indicators. The most reliable, efficient, and accurate means to diagnose the washer fluid level
indicator, the instrument cluster, the FCM, or the electronic message inputs and outputs related to
the washer fluid indicator requires the use of a diagnostic scan tool.

Description and Operation
Washer Fluid Level Indicator: Description and Operation
A washer fluid indicator is standard equipment on all instrument clusters. The washer fluid indicator
consists of the text "LOW WASH", which appears in the lower portion of the odometer
Vacuum-Fluorescent Display (VFD) unit.
The odometer VFD is soldered onto the cluster electronic circuit board and is visible through a
window with a smoked clear lens located on the lower edge of the tachometer gauge dial face of
the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly visible
when it is not illuminated. The "LOW WASH" text appears in an amber color and at the same
lighting level as the odometer/trip odometer information when it is illuminated by the instrument
cluster electronic circuit board. The washer fluid indicator is serviced as a unit with the VFD in the
instrument cluster.
The washer fluid indicator gives an indication to the vehicle operator that the fluid level in the
washer reservoir is low. This indicator is controlled by the instrument cluster circuit board based
upon cluster programming and electronic messages received by the cluster from the Front Control
Module (FCM) (also known as the Integrated Power Module/IPM or Power Distribution
Center/PDC) over the Programmable Communications Interface (PCI) data bus.
The washer fluid indicator is completely controlled by the instrument cluster logic circuit, and that
logic will only allow this indicator to operate when the instrument cluster receives a battery current
input on the fused ignition switch output (run-start) circuit. Therefore, the indicator will always be off
when the ignition switch is in any position except On or Start. The indicator only illuminates when it
is switched to ground by the instrument cluster circuitry. The instrument cluster will turn on the
washer fluid indicator for the following reasons:
- Washer Fluid Indicator Lamp-On Message - Each time the cluster receives a washer fluid
indicator lamp-on message from the FCM indicating that a low washer condition has been detected
for sixty consecutive seconds, the washer fluid indicator is illuminated and a single chime tone is
sounded. The indicator remains illuminated until the cluster receives a washer fluid indicator
lamp-off message for sixty consecutive seconds from the FCM or until the ignition switch is turned
to the Off position, whichever occurs first. The chime tone feature will only repeat during the same
ignition cycle if the washer fluid indicator is cycled off and then on again by the appropriate washer
fluid lamp messages from the FCM.
- Actuator Test - Each time the cluster is put through the actuator test, the washer fluid indicator will
be turned on, then off again during the VFD portion of the test to confirm the functionality of the
VFD and the cluster control circuitry.
The FCM continually monitors the washer fluid level switch in the washer reservoir to determine the
level of the washer fluid. The FCM then sends the proper washer fluid indicator lamp-on and
lamp-off messages to the instrument cluster. For further diagnosis of the washer fluid indicator or
the instrument cluster circuitry that controls the indicator, refer to testing.
For proper diagnosis of the washer fluid level switch, the FCM, the PCI data bus, or the electronic
message inputs to the instrument cluster that control the washer fluid indicator, a diagnostic scan
tool is required.

Description and Operation
Windshield Washer Hose: Description and Operation
The washer plumbing consists of a small diameter rubber reservoir washer hose that is routed from
the barbed outlet nipple of the electric washer pump/motor unit on the washer reservoir through a
trough molded into the back of the reservoir above the washer pump to the engine compartment
washer hose to the right side of the engine cooling module. On SRT-10 models or those equipped
with an optional diesel engine, the reservoir washer hose is routed through routing clips on the top
of the radiator fan shroud from the washer reservoir on the left side of the radiator to the engine
compartment washer hose on the right side of the radiator.
The engine compartment washer hose is contained within the right headlamp and dash wire
harness (2), which is routed through the engine compartment along the top of the right front fender
wheel house to the dash panel. This hose is connected to the washer reservoir washer hose at one
end (5) and to the cowl plenum washer hose at the other end (3) with molded plastic in-line fittings
that have a barbed nipple on each end.
The cowl plenum washer hose (4) is routed from the engine compartment into the cowl plenum
area through a trough formation located near the right end of the cowl plenum cover/grille panel.
The cowl plenum washer hose is connected to the washer system check valve/eye fitting on the
underside of the cowl plenum cover/grille panel. The cowl plenum washer hose and the two washer
nozzle hoses are routed through integral routing clips on the underside of the cowl plenum
cover/grille panel. The cowl plenum washer hose is connected to one nipple on the eye fitting and
the two washer nozzle hoses are connected to the other two nipples. The washer nozzle hoses are
then routed along the underside of the cowl plenum cover/grille panel to the two washer nozzles.
Washer hose is available for service only as roll stock, which must then be cut to length. The
molded plastic washer hose fittings cannot be repaired. If these fittings are faulty or damaged, they
must be replaced.
Washer fluid in the washer reservoir is pressurized and fed by the washer pump/motor through the
washer system plumbing and fittings to the two washer nozzles. Whenever routing the washer
hose or a wire harness containing a washer hose, it must be routed away from hot, sharp, or
moving parts; and, sharp bends that might pinch the hose must be avoided.

Windshield Washer Pump: Description and Operation
The washer pump/motor unit (1) is located on the rearward facing surface of the washer reservoir,
in the right (except SRT-10 and diesel) or left (SRT-10 and diesel only) front corner of the engine
compartment. A small permanently lubricated and sealed electric motor is coupled to the rotor-type
washer pump.
A seal flange with a barbed inlet nipple (6) on the pump housing passes through a rubber grommet
seal installed in a dedicated mounting hole of the washer reservoir. A removable molded plastic
filter screen (7) inserted into the inlet nipple prevents most debris from entering the pump housing.
When the pump is installed in the reservoir a barbed outlet nipple (5) on the pump housing
connects the unit to the washer system through a short washer reservoir hose.
The washer pump/motor unit is retained on the reservoir by the interference fit between the barbed
pump inlet nipple and the grommet seal, which is a light press fit. The top of the washer pump is
also secured to the washer reservoir by the use of a snap post (2) on the motor housing and a
snap post receptacle molded into the reservoir that allows for mounting of the washer pump without
the use of fasteners. An integral connector receptacle (3) on the top of the motor housing connects
the unit to the vehicle electrical system.
The washer pump/motor unit cannot be repaired. If faulty or damaged, the entire washer
pump/motor unit must be replaced.
The washer pump/motor unit features a small Direct Current (DC) electric motor. The motor is
connected to the vehicle electrical system through a single take out and two-cavity connector of the
right (except SRT-10 and diesel) or left (SRT-10 and diesel only) headlamp and dash wire harness.
The motor is grounded at all times through another take out of the right (except SRT-10 and diesel)
or left (SRT-10 and diesel only) headlamp and dash wire harness. On models except SRT-10 or
diesel, a single eyelet terminal connector is secured by a nut to a ground stud located on the right
front fender inner shield in the engine compartment. On SRT-10 or diesel models, an eyelet
terminal connector is secured by a ground screw to the left front fender inner shield in the engine
compartment.
The motor receives battery current on a washer pump/motor control circuit. The washer
pump/motor control circuit is energized through a high side driver within the Front Control Module
(FCM) whenever the FCM receives an electronic message requesting washer system operation
from the ElectroMechanical Instrument Cluster (EMIC) over the Programmable Communications
Interface (PCI) data bus. The EMIC monitors a resistor multiplexed hard wired input from the
momentary washer switch contacts within the multi-function switch on the steering column to
determine when it should issue the electronic message requesting washer system operation.
Washer fluid is gravity-fed from the washer reservoir to the inlet side of the washer pump. When
the pump motor is energized, the motor spins the rotor within the washer pump. The spinning pump
rotor pressurizes the washer fluid and forces it through the pump outlet nipple, the washer
plumbing, and the washer nozzles onto the windshield glass.
The washer pump/motor unit may be diagnosed using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the EMIC,
the FCM, the PCI data bus or the electronic messages used to control the operation of the washer
pump/motor unit. The most reliable, efficient, and accurate means to diagnose the washer
pump/motor unit, the EMIC, the FCM, the PCI data bus, and the electronic messages for washer
pump/motor unit control requires the use of a diagnostic scan tool.

Description and Operation
Windshield Washer Reservoir: Description and Operation
Except on SRT-10 and diesel models, the molded plastic washer fluid reservoir (1) is integral to the
engine coolant overflow bottle (4) located on the right rearward facing surface of the engine cooling
module shroud in the right front corner of the engine compartment. On SRT-10 and diesel models,
the molded plastic washer fluid reservoir is separate from the engine coolant overflow bottle and is
mounted on the rearward facing surface of the left vertical member of the radiator support in the
engine compartment. These reservoirs are constructed of a translucent plastic that allows the fluid
level to be inspected without removing the reservoir caps.
A round bright yellow plastic cap (2) with a rubber seal snaps over the open end of the washer
reservoir filler neck and can be easily distinguished from the coolant overflow bottle cap (3) by an
International Control and Display Symbol icon for "Windshield Washer" and the text "Washer Fluid
Only" molded into it. The cap hinges on and is secured to a molded-in hook formation on the top of
the reservoir just behind the filler neck when it is removed for inspecting or adjusting the fluid level
in the reservoir.
Except on SRT-10 and diesel models, the washer reservoir is secured to the cooling module
radiator shroud with two integral tabs at the bottom, and through two integral mounting brackets
with two screws at the top. The two bottom tabs are inserted into two slots near the bottom of the
shroud, while the two screws secure the mounting brackets to integral mounting points near the top
of the shroud. On SRT-10 and diesel models, the washer reservoir is secured with two screws
through integral mounting brackets to the left vertical member of the radiator support.
There are separate, dedicated holes on the lower rearward facing side of either reservoir provided
for the mounting of the washer/pump motor unit (6) and the washer fluid level switch (5). A snap
post receptacle for the washer pump and a routing trough for the washer hose are molded into both
reservoirs to allow for mounting of the washer pump/ motor unit without the use of fasteners.
Except on SRT-10 and diesel models, the washer reservoir is serviced only as a unit with the
engine coolant reserve bottle. A washer reservoir cannot be repaired and, if faulty or damaged, the
unit must be replaced. The washer pump/motor unit, the washer fluid level switch, their rubber
grommet seals, as well as the reservoir filler cap are each available for individual service
replacement.
The washer fluid reservoir provides a secure, on-vehicle storage location for a large reserve of
washer fluid for operation of the washer system. The washer reservoir filler neck provides a clearly
marked and readily accessible point from which to add washer fluid to the reservoir.
The washer/pump motor unit is located in a sump area near the bottom of the reservoir to be
certain that washer fluid will be available to the pump as the fluid level in the reservoir becomes
depleted. The washer fluid level switch is mounted just above the washer pump inlet nipple in the
sump area of the reservoir so that there will be adequate warning to the vehicle operator that the
washer fluid level is low, well before the washer system will no longer operate.

Description and Operation
Windshield Washer Spray Nozzle: Description and Operation
The fluidic washer nozzles (1) are constructed of molded plastic. Each nozzle has two integral
latches (2) and an anti-rotation tab (4) that secure them in dedicated holes in the cowl plenum
cover/grille panel located near the base of the windshield The domed upper surface of the washer
nozzle is visible on the top of the plenum cover/grille panel, and the nozzle orifice (5) is oriented
towards the windshield glass. The washer plumbing fittings (3) for the washer nozzles extend
below the cowl plenum cover/grille panel. The cowl plenum cover/grille panel must be removed
from the vehicle to access the nozzles for service. The washer nozzles cannot be adjusted or
repaired. If faulty or damaged, they must be replaced.
The two washer nozzles are designed to dispense washer fluid into the wiper pattern area on the
outside of the windshield glass. Pressurized washer fluid is fed to each nozzle from the washer
reservoir by the washer pump/ motor unit through a single hose, which is attached to a barbed
nipple on each washer nozzle below the cowl plenum cover/grille panel. A fluidic matrix within the
washer nozzle causes the pressurized washer fluid to be emitted from the nozzle orifice as an
oscillating stream to more effectively cover a larger area of the glass to be cleaned.

Dodge Ram 1500 4wd Workshop Manual (Truck V8-5.7L VIN D (2005))
Dodge Workshop Manuals > Wiper and Washer Systems > Wiper Arm > Component Information > Description and
Operation
Wiper Arm: Description and Operation
The wiper arms are the rigid members located between the wiper pivots protruding from the cowl
plenum cover/grille panel near the base of the windshield and the wiper blades on the windshield
glass. These wiper arms feature an over-center hinge that allows easy access to the windshield
glass for cleaning.
The wiper arms each have a die cast metal pivot end (3) with a large internally serrated socket
formation at one end. A key (4) within the socket formation indexes the wiper arm to a keyway in
the pivot shaft to provide wiper alignment, and a spring-loaded latch (5) on the underside of the
pivot end locks the unit to the pivot shaft when it is fully installed. The right and left wiper arms for
this model are not interchangeable, as the right wiper arm is slightly longer than the left one.
The wide end of a tapered, stamped steel channel (8) hinges on and is secured with a hinge pin (6)
to the blade end of both the right and left wiper arm pivot ends. One end of a long, rigid, stamped
steel strap (2), with a small hole near its pivot end, is riveted and crimped within the narrow end of
the stamped steel channel. The tip of the wiper blade end of this strap is bent back under itself to
form a small hook (1). Concealed within the stamped steel channel, one end of a long spring (7) is
engaged with a wire hook on the underside of the die cast pivot end, while the other end of the
spring is hooked through the small hole in the steel strap. The entire wiper arm has a satin black
finish applied to all of its visible surfaces.
A wiper arm cannot be adjusted or repaired. If damaged or faulty, the entire wiper arm unit must be
replaced.
The wiper arms are designed to mechanically transmit the motion from the wiper pivots to the wiper
blades. The wiper arm must be properly indexed to the wiper pivot in order to maintain the proper
wiper blade travel on the glass.
The serrated and keyed socket formation in the wiper arm pivot end interlocks with the serrations
and keyway on the outer circumference of the wiper pivot shaft, providing positive engagement and
alignment of this connection. The latch positively locks the wiper arm to the wiper pivot shaft when
the arm is fully installed. The spring-loaded wiper arm hinge controls the down-force applied
through the tip of the wiper arm to the wiper blade on the glass. The hook formation on the tip of
the wiper arm provides a cradle for securing and latching the wiper blade pivot block to the wiper
arm.

DISCUSSION:
Windshield wiper blades/elements are frequently replaced unnecessarily. Because of the
environmental conditions vehicles can be operated in, a film can build up on both the windshield
and the windshield wiper elements that will cause poor cleaning/streaking of the windshield, and in
some instances, a chattering condition as the wipers blades travel across the windshield.
Replacement of the wiper blades/elements is normally NOT required to correct streaking issues. A
simple NORMAL MAINTENANCE cleaning of the wiper blades/elements and windshield is all that
is required.
If the wipe pattern appears to be streaky or if there is chatter and no damage to the wiper
blades/elements is obvious, the following steps should be performed:
1. Use a soft cloth or sponge & squeegee and MOPAR Windshield Washer Solvent (p/n
04318067AB, 16 Oz. bottle or p/n 04318068AB, 32 Oz. bottle), MOPAR Glass Cleaner (p/n
04897623AB, 16 Oz. bottle) or a solution of 50/50 alcohol and water, to wash the windshield.
2. Raise the wiper blades off the glass and clean the wiper blade elements (rubber insert) with
MOPAR Windshield Washer Solvent or a solution of 50/50 alcohol and water and a soft cloth,
paper towel or sponge.
3. Return the wiper blades to their normal operating position and function the washer system. If the
wiper blades/elements are not streaking the windshield or chattering, replacing the blade
assembly(ies) is not necessary. If the wipe pattern is still objectionable, repeat step 2 several times.
If the wipe pattern is still objectionable, replace the wiper blades/elements.

Wiper Blade: Description and Operation
Each wiper blade is secured by an integral latching pivot block (3) to the hook formation on the tip
of each wiper arm, and rests on the glass near the base of the windshield when the wipers are not
in operation. The wiper blade consists of the following components:
- Superstructure (1) - The superstructure includes several stamped steel bridges and links with
claw formations that grip the wiper blade element. Also included in this unit is the latching, molded
plastic pivot block that secures the superstructure to the wiper arm. All of the metal components of
the wiper blade have a satin black finish applied.
- Element (2) - The wiper element or squeegee is the resilient rubber member of the wiper blade
that contacts the glass.
- Flexor (7) - The flexor is a rigid metal component running along the length of each side of the
wiper element where it is gripped by the claws (6) of the superstructure.
All models have two 60.00 centimeter (23.62 inch) long wiper blades with non-replaceable rubber
elements (squeegees). The wiper blades cannot be adjusted or repaired. If faulty, worn, or
damaged the entire wiper blade unit must be replaced.
The wiper blades are moved back and forth across the glass by the wiper arms when the wipers
are being operated. The wiper blade superstructure is the flexible frame that grips the wiper blade
element and evenly distributes the force of the spring-loaded wiper arm along the length of the
element. The combination of the wiper arm force and the flexibility of the superstructure makes the
element conform to and maintain proper contact with the glass, even as the blade is moved over
the varied curvature that may be encountered across the glass surface.
The wiper element flexor provides the claws of the blade superstructure with a rigid, yet flexible
component on the element which can be gripped. The rubber element is designed to be stiff
enough to maintain an even cleaning edge as it is drawn across the glass, yet resilient enough to
conform to the glass surface and flip from one cleaning edge to the other each time the wiper blade
changes directions.

Wiper Motor: Description and Operation
The wiper module is secured with screws through three rubber grommet-type insulators (5) to the
cowl plenum panel. The module is concealed beneath the molded plastic cowl plenum cover/grille
panel between the base of the windshield and the rear edge of the hood panel. The ends of the
pivot shafts protruding through openings in the cowl plenum cover/grille panel to drive the wiper
arms and blades are the only visible components of the wiper module. The wiper module consists
of the following major components:
- Bracket - The wiper module bracket consists of a long tubular steel main member (2) that has a
die cast pivot bracket (1) at each end to which the two wiper pivots are secured. A stamped steel
clamp secures the center of the tubular member to the die cast bracket integral to the wiper motor
with two screws.
- Crank Arm (10) - The wiper motor crank arm is a stamped steel unit with a slotted hole on the
driven end that is secured to the wiper motor output shaft with a nut, and has a ball stud secured to
the drive end.
Linkage (2) - Two stamped steel drive links connect the wiper motor crank arm to the wiper pivot
lever arms. The left side drive link has a plastic socket-type bushing (6) on each end. The right side
drive link has a plastic socket-type bushing on one end, and a plastic sleeve-type bushing on the
other end. The socket-type bushing on one end of each drive link is snap-fit over the ball stud on
the lever arm (8) of its respective pivot. The right side drive link sleeve-type bushing end is then fit
over the motor crank arm ball stud, and the other socket-type bushing of the left side drive link is
snap-fit over the exposed end of the wiper motor crank arm ball stud.
- Motor (11) - The wiper motor features an integral die cast bracket to which the wiper module
bracket is secured with a stamped steel clamp and two screws near the top and which has a single
rubber insulated mounting ear at the bottom. This die casting also serves as the wiper motor
transmission housing from which the wiper motor output shaft exits. A nut secures the wiper motor
crank arm to the motor output shaft. The two-speed permanent magnet wiper motor features an
integral transmission, an internal park switch, and an internal automatic resetting circuit breaker.
- Pivots (2) - The two front wiper pivots are secured within the die cast pivot brackets on the
outboard ends of the wiper module main member. The lever arms that extend from the center of
the pivot shafts each have a ball stud on their end. The upper end of each pivot shaft where the
wiper arms will be fastened each has a serrated driver with a keyway. The lower ends of the pivot
shafts are installed through lubricated bushings in the pivot brackets and are secured with snap
rings.
The wiper module cannot be adjusted or repaired. If any component of the module is faulty or
damaged, the entire wiper module unit must be replaced.
The wiper module operation is controlled by the battery current inputs received by the wiper motor
through the wiper on/off and wiper high/low relays. The wiper motor speed is controlled by current
flow to either the low speed or the high speed set of brushes. The park switch is a single pole,
single throw, momentary switch within the wiper motor that is mechanically actuated by the wiper
motor transmission components. The park switch alternately opens and closes the wiper park
switch sense circuit to ground, depending upon the position of the wipers on the glass. This feature
allows the motor to complete its current wipe cycle after the wiper system has been turned Off, and
to park the wiper blades in the lowest portion of the wipe pattern. The automatic resetting circuit
breaker protects the motor from overloads.
The wiper motor crank arm, the two wiper linkage members, and the two wiper pivots mechanically
convert the rotary output of the wiper motor to the back and forth wiping motion of the wiper arms
and blades on the glass.

Operation > Wiper High/Low Relay
Wiper Relay: Description and Operation Wiper High/Low Relay
The wiper high/low relay is a conventional International Standards Organization (ISO) micro relay.
Relays conforming to the ISO specifications have common physical dimensions, current capacities,
terminal patterns, and terminal functions. This relay is contained within a small, rectangular,
molded plastic housing and is connected to all of the required inputs and outputs through five
integral male spade-type terminals that extend from the relay base plate.
The wiper high/low relay is located in the Power Distribution Center (PDC)/Integrated Power
Module (IPM) in the engine compartment near the battery. Refer to the layout label on the
underside of the PDC cover for specific relay cavity assignment information. The wiper high/low
relay cannot be adjusted or repaired and, if faulty or damaged, the unit must be replaced.
The wiper high/low relay is an electromechanical switch that uses a low current input from the Front
Control Module (FCM) to control a high current output to the wiper motor. The movable common
feed contact point is held against the fixed normally closed contact point by spring pressure. When
the relay coil is energized, an electromagnetic field is produced by the coil windings. This
electromagnetic field draws the movable relay contact point away from the fixed normally closed
contact point, and holds it against the fixed normally open contact point. When the relay coil is
de-energized, spring pressure returns the movable contact point back against the fixed normally
closed contact point. A resistor is connected in parallel with the relay coil in the relay, and helps to
dissipate voltage spikes and electromagnetic interference that can be generated as the
electromagnetic field of the relay coil collapses.
The wiper high/low relay terminals are connected to the vehicle electrical system through a
connector receptacle in the Power Distribution Center (PDC)/Integrated Power Module (IPM). The
inputs and outputs of the wiper high/low relay include:
- Common Feed Terminal - The common feed terminal (30) is connected to the output of the wiper
on/off relay at all times through the wiper on/off relay output circuit.
- Coil Ground Terminal - The coil ground terminal (85) is connected to a control output of the Front
Control Module (FCM) through a wiper high/low relay control circuit. The FCM controls wiper motor
operation by controlling a ground path through this circuit.
-
Coil Battery Terminal - The coil battery terminal (86) receives battery current when the ignition
switch is in the On or Accessory positions from a fuse in the PDC/IPM through a fused ignition
switch output (run-acc) circuit.
- Normally Open Terminal - The normally open terminal (87) is connected to the high speed brush
of the wiper motor through a wiper high/low relay high speed output circuit, and is connected to the
high speed brush whenever the relay is energized.
- Normally Closed Terminal - The normally closed terminal (87A) is connected to the low speed
brush of the wiper motor through a wiper high/low relay low speed output circuit, and is connected
to the low speed brush whenever the relay is de-energized.
The wiper high/low relay can be diagnosed using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the
ElectroMechanical Instrument Cluster (EMIC), the FCM, or the electronic message inputs to or
outputs from the EMIC and the FCM that control the operation of the wiper high/low relay. The
most reliable, efficient, and accurate means to diagnose the wiper high/low relay, the EMIC, the
FCM, or the electronic message inputs and outputs related to the wiper high/low relay operation
requires the use of a diagnostic scan tool.
