IMPORTANT: Some of the involved vehicles may be in dealer used vehicle inventory. Dealers should complete this recall service on these vehicles before retail delivery. Dealers should also perform this recall on vehicles in for service. Involved vehicles can be determined by using the VIP inquiry process. Subject Electrolyte (battery acid) from aftermarket batteries may leak onto an Antilock Brake System (ABS) wiring connector on about 43,000 of the above vehicles. This may cause the wiring to corrode and short circuit, which can result in an underhood fire. Repair All vehicles must have a revised battery tray installed that will protect the ABS control module wiring harness connector from future electrolyte leakage. A cowl seal extension must also be installed on all vehicles to redirect any water draining from the windshield away from the battery. The ABS control module wiring harness and connector must be inspected for electrolyte damage and repaired if necessary. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Technical Service Bulletins > Recalls: > D20 > Sep > 04 > Recall - ABS Wiring Corrosion > Page 33 Parts Information Completion Reporting and Reimbursement Claims for vehicles that have been serviced must be submitted on the DealerCONNECT Claim Entry Screen located on the Service tab.

The modulated hydraulic pressure is used to prevent wheel lock up during braking. The CAB also provides a vehicle speed signal (VSS) to the powertrain control module. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 116 Electronic Brake Control Module: Description and Operation With Four Wheel Antilock Brakes CAB/HCU The Controller Antilock Brake (CAB) is mounted on the top of the hydraulic control unit. The CAB operates the ABS system and is separate from other vehicle electrical circuits. CAB voltage source is through the ignition switch in the RUN position. The CAB contains dual microprocessors. A logic block in each microprocessor receives identical sensor signals. These signals are processed and compared simultaneously. The CAB 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 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 CAB needs to be replaced the rear axle type and tire revolutions per mile must be programmed into the new CAB. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 117 Electronic Brake Control Module: Description and Operation With Rear Wheel Antilock Brakes RWAL CAB The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring, and controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics. - Monitors the RWAL brake system for proper operation. - Controls the RWAL valve solenoids. NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB. SYSTEM SELF-TEST When the ignition switch is turned ON the microprocessor RAM and ROM are tested. If an error occurs during the test a DTC will be set into the RAM memory. However it is possible the DTC will not be stored in memory if the error has occurred in the RAM module were the DTCs are stored. Also it is possible a DTC may not be stored if the error has occurred in the ROM which signals the RAM to store the DTC. CAB INPUTS The CAB continuously monitors the speed of the differential ring gear by monitoring signals generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency when it recognizes the ring gear decelerating too rapidly. The CAB monitors the following inputs to determine when a wheel locking tendency may exists: Rear Wheel Speed Sensor - Brake Lamp Switch - Brake Warning Lamp Switch - Reset Switch CAB OUTPUTS The CAB controls the following outputs for antilock braking and brake warning information: RWAL Valve - ABS Warning Lamp - Brake Warning Lamp Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Service and Repair > With Four Wheel Antilock System Electronic Brake Control Module: Service and Repair With Four Wheel Antilock System NOTE: If the Controller Antilock Brake (CAB) needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB.

The terminal designations and functions are the same as a conventional ISO relay. However, the micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay case dimensions are smaller than those of the conventional ISO relay. The compressor clutch relay is a electromechanical device that switches battery current to the compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the relay. The PCM responds to inputs from the heater-A/C mode control switch, the low pressure cut-off switch, the high pressure cut-off switch, and the fin sensing cycling clutch switch. See Compressor Clutch Relay in the Diagnosis and Testing for more information. Power Distribution Center (PDC) Location The compressor clutch relay is located in the Power Distribution Center (PDC) in the engine compartment. Refer to the PDC label for relay identification and location. The compressor clutch relay cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - HVAC > Compressor Clutch Relay > Component Information > Description and Operation > A/C Compressor Clutch Relay Description > Page 151 Compressor Clutch Relay: Description and Operation A/C Compressor Clutch Relay-PCM Output AIR CONDITIONING (A/C) CLUTCH RELAY - PCM OUTPUT Power Distribution Center (PDC) Location The A/C relay is located in the Power Distribution Center (PDC). The PDC is located in the engine compartment next to the battery. Refer to label on PDC cover for relay location. The Powertrain Control Module (PCM) activates the A/C compressor through the A/C clutch relay. The PCM regulates A/C compressor operation by switching the ground circuit for the A/C clutch relay on and off. When the PCM receives a request for A/C, it will adjust idle air control (IAC) motor position. This is done to increase idle speed. The PCM will then activate the A/C clutch through the A/C clutch relay. The PCM adjusts IAC stepper motor position to compensate for increased engine load from the A/C compressor. By switching the ground path for the relay on and off, the PCM is able to cycle the A/C compressor clutch. This is based on changes in engine operating conditions. If, during A/C operation, the PCM senses low idle speeds or a wide open throttle condition, it will de-energize the relay. This prevents A/C clutch engagement. The relay will remain de-energized until the idle speed increases or the wide open throttle condition exceeds 15 seconds or no longer exists. The PCM will also de-energize the relay if coolant temperature exceeds 125°C (257°F) or low or high system pressure exists. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - HVAC > Compressor Clutch Relay > Component Information > Description and Operation > Page 152 Compressor Clutch Relay: Testing and Inspection COMPRESSOR CLUTCH RELAY Relay Test Compressor Clutch Relay The compressor clutch relay is located in the Power Distribution Center (PDC).

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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.

Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 167 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 179 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 180 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 181 Audible Warning Device Control Module: Connector Views Central Timer Module C1 Central Timer Module C2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 182 Audible Warning Device Control Module: Electrical Diagrams Central Timer Module 8w-45-2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 183 8w-45-3 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 184 8w-45-4 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 185 8w-45-5 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 186 8w-45-6 NOTE: To view sheets referred to in these diagrams, see Complete Body and Chassis Diagrams.

In addition to serving as the security system module, the CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, and a Remote Keyless Entry (RKE) module in a single unit. The CTM is also able to control and integrate many of the additional electronic functions and features included on models with this option. The CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network 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. Intermittent wipe, wipe-after-wash, and speed sensitive intermittent wipe are some of the features that the CTM supports. The intermittent wipe relay is one of the outputs that the CTM can control. The CTM is programmed to energize or de-energize the intermittent wipe relay in response to certain inputs from the windshield wiper and washer switches and from the windshield wiper motor park switch. For the speed sensitive intermittent wipe feature, the CTM also uses vehicle speed messages, which are received on the CCD data bus from the Powertrain Control Module (PCM). The CTM is mounted under the instrument panel, to the inboard side of the left center instrument panel support. For diagnosis of the CTM or the CCD data bus, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. The CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless Entry (RKE) systems. The CTM receives hard wired inputs from the power lock switches, CCD message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and coded radio frequency inputs from the RKE transmitters. In response to those and many other inputs, the internal programming of the CTM sends the proper outputs to control the power lock motors, the headlamp and horn relays, and the courtesy lamps. The RKE receiver within the CTM has a memory function to retain the vehicle access codes of at least one, but no more than four RKE transmitters. The receiver is designed to retain the transmitter codes in memory, even if the battery is disconnected. Some of the features and functions of the power lock, illuminated entry and RKE systems made possible because of the communication of the CTM on the CCD data bus network include: - A door-lock inhibit feature which prevents the power lock system from being energized with a power door lock switch if the key is in the ignition and/or the headlamps are on. However, the locks can still be operated manually, with a key, or energized with the RKE transmitter. - A delay lock feature. With the delay lock feature, if a side or rear door is still open when a lock request is received by the CTM, the module will automatically cycle all of the power lock motors to lock five seconds after the doors are closed. - An enhanced accident response feature will unlock all doors, then prevent the power door lock system from locking the doors for a predetermined time interval, after receiving a CCD message from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course, these responses are dependent upon functional battery power and wiring circuitry following the impact. - Rolling door locks is a programmable feature of the power lock system. This feature will automatically lock all of the doors and the liftgate after the vehicle reaches a speed of about 24 kilometers-per hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour). - A programmable feature of the RKE system is the enabling or disabling of the horn chirp following activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the horn chirp duration (twenty or forty milliseconds) can be selected. One of the features that the CTM supports and controls is the Vehicle Theft Security System (VTSS). In the VTSS, the CTM receives hard-wired inputs from the door ajar, front door lock cylinder, and ignition switches. The programming in the CTM allows it to process the information from these inputs and send control outputs to energize or de-energize the headlamp (or security) relay, horn relay, and the security lamp. The CTM also sends CCD data bus messages to the Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS. The CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry (RKE) systems, which are integrated into the arming, disarming, and triggering functions of the VTSS. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Page 190 OPERATION The Base RAM VAN body system is composed of individual modules. Because the stand-alone modules do not communicate on the CCD bus, they cannot be diagnosed using the DRB. For concerns about the Base RAM VAN, refer to the appropriate service procedures. The Base version can be identified by the sound of the Key-In Ignition BUZZER. Some of the functions and features that the CTM supports or controls include: - CCD Bus Communication - Chimes for the following conditions: Headlamps on with ignition off and driver door open warning - Key in ignition with ignition off and driver door open warning - ABS lamp illumination - Airbag lamp warning - Check gauges lamp warning - Low fuel lamp warning - Low washer fluid lamp warning - Seat belt reminder lamp warning - Transmission oil temperature lamp warning - Courtesy Lamp Controls/Illuminated Entry - Intermittent wipe control - Enhanced Accident Response - Horn chirp upon door lock with RKE (programmable) - Power lock delay - Power lock inhibit - Remote Keyless Entry (RKE) - Rolling door locks (programmable) - Speed sensitive intermittent wipe - Vehicle Theft Security System (VTSS) - Wipe after wash. The module is located on the left center instrument panel support. It contains a white 18-way and a green 14-way connector.

The terminal designations and functions are the same as a conventional International Standards Organization (ISO) relay. The horn relay is a electromechanical device that switches battery current to the horn when the horn switch grounds the relay coil. The horn relay is located in the junction block on the driver side end of the instrument panel in the passenger compartment. If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the junction block until further diagnosis is completed. The horn relay is an ISO micro-relay. Relays confirming to the ISO specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions. 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 horn relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION 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 the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Horn Relay > Component Information > Locations > Page 212 Horn Relay: Testing and Inspection Horn Relay The horn relay is located in the junction block on the driver side end of the instrument panel in the passenger compartment.

Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System Body Control Module: Description and Operation Airbag System Airbag System Description AIRBAG SYSTEM The Airbag Control Module (ACM) is secured to a bracket on the floor panel below the drivers seat. The ACM contains a microprocessor, the impact sensor, and energy storage capacitor. The microprocessor contains the airbag system logic. The ACM system logic includes On-Board Diagnostics (OBD) capability, and communicates with the instrument cluster circuitry on the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor in the ACM monitors the impact sensor signal and the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster on the CCD data bus to turn on the airbag indicator lamp. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbag system components. Only one impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags, for one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. The airbag warning lamp is the only point at which the customer can observe "symptoms" of a system malfunction, Whenever the ignition key is turned to the RUN or START position, the MIC performs a lamp check by turning the AIRBAG warning lamp ON for 6-8 seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the system or the MIC lamp circuit may be internally shorted to ground. If the lamp comes ON and stays ON for a period longer than 6-8 seconds then goes OFF, there is usually an intermittent problem in the system. The MIC monitors the airbag warning lamp and seat belt warning lamp during the bulb check for a defective bulb or lamp driver circuit. The MIC tests the airbag lamp during the cluster bulb check and substitutes the seat belt lamp if the airbag lamp is defective. If the airbag lamp is defective the MIC will turn the seat belt light ON and OFF approximately 30 times to warn the driver that the airbag lamp is defective. The lamp status is sent to the ACM continuously via a CCD bus message. The seat belt lamp acts as a backup in the event that the AIRBAG lamp is defective. This information is sent to the ACM continuously via a CCD bus message. Perform the WARNING LAMP BULB OR DRIVER procedure in this book to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated with no active DTC's The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. Service and general information labels about the airbag system can be found on the driver's sun visor, the glove box door, and in the engine compartment. WARNING: FAILURE TO HAVE THE AIRBAG SYSTEM PROPERLY SERVICED BY AN AUTHORIZED DEALER MAY LEAD TO POSSIBLE INJURY IN THE EVENT OF AN ACCIDENT.

The module is mounted directly to the steering wheel. Located under the trim cover are the horn switch, the airbag cushion, and the airbag cushion supporting components. The airbag module includes a housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator seals the hole in the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. The protective trim cover is fitted to the front of the airbag module and forms a decorative cover in the center of the steering wheel. Upon airbag deployment, this cover will split at a predetermined breakout line. THE AIRBAG MODULE INFLATOR ASSEMBLY CONTAINS SODIUM AZIDE AND POTASSIUM NITRATE. THESE MATERIALS ARE POISONOUS AND EXTREMELY FLAMMABLE.

Clockspring CLOCKSPRING The clockspring is mounted on the steering column behind the steering wheel. This assembly consists of a plastic housing which contains a flat, ribbon-like, electrically conductive tape that winds and unwinds with the steering wheel rotation. The clockspring is used to maintain a continuous electrical circuit between the instrument panel wire harness and the driver side airbag module, the horn switch, and the vehicle speed control switches on vehicles that are so equipped. The clockspring must be properly centered when it is installed on the steering column following any service removal, or it will be damaged. The clockspring cannot be repaired it must be replaced. Passenger Airbag Module (PAB) PASSENGER AIRBAG MODULE (PAB) The airbag door in the instrument panel top cover above the glove box is the most visible part of the passenger side airbag system. Located under the airbag door is the airbag cushion and it's supporting components. The airbag module includes a housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator includes a small canister of highly compressed argon gas. The inflator seals the hold in the airbag cushion so it can discharge the compressed gas it contains directly into the cushion when supplied with the proper electrical signal. The airbag door has a living hinge at the top, which is secured to the instrument panel top cover. The door also has predetermined breakout lines concealed beneath its decorative cover. Upon airbag deployment the airbag door will split at the breakout lines and the door will pivot out of the way. The airbag module is secured at the bottom to the steel structural base of the instrument panel above the glove box opening. The airbag door is serviced as a unit with the passenger side airbag module, and includes the two passenger heating and air conditioning panel outlet housings. Following an airbag deployment, the airbag module and the instrument panel assembly must be replaced. Passenger Airbag On/Off Switch PASSENGER AIRBAG ON/OFF SWITCH The passenger side airbag ON/OFF switch is located on the instrument panel. To de-activate the passenger side airbag, turn the key actuator switch from the horizontal position to a slanted position (pointing to the "OFF" light indicator), approximately 45 degrees clockwise from the "ON" position. Rotating the key actuator switch 45 degrees clockwise, remove the key completely from the switch and verify that the switch actuator hole stays in the new position (45 degrees clockwise from horizontal). The switch is spring loaded to the "ON" position. It will return to the "ON" position unless you remove the key. When the IGNITION in ON, this procedure will illuminate the "OFF" light indicator on the passenger airbag ON/OFF switch. To re-enable the passenger side airbag, reverse the procedure above so that the key switch actuator is returned to a horizontal position. NOTE: DO NOT TURN IGNITION ON WITH KEY IN SWITCH. DO NOT TURN SWITCH WITH IGNITION ON. DO NOT LEAVE KEY IN SWITCH. THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG ON/OFF SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED.

While the vehicle is off the illuminated entry feature can be activated in the following ways. Whenever a door is opened - When the vehicle is unlocked with a key - When the CTM receives a valid unlock signal from the RKE transmitter The illuminated entry will remain ON for 30 seconds after the last door is closed, turn OFF immediately after ignition is turned ON, or turn OFF when the CTM receives a LOCK message from the RKE transmitter. 15 Minute Illumination Timeout If the ignition is OFF and either front door is open, interior illumination will terminate after 15 minutes. If either front door is open and the ignition is turned in the RUN or ACCESSORY position, interior illumination will continue until the ignition is turned OFF. Once the ignition is OFF, if either front door remains open, the 15 minute interior illumination timeout will begin. Note: This timeout feature does not apply to either auxiliary door or the dome lamp switch which are hardwired to the courtesy lamps. The auxiliary door switches are also wired to the CTM to operate illuminated entry. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 225 Body Control Module: Description and Operation Central Timer Module CENTRAL TIMER MODULE (CTM) The AB RAM VAN has two different body electrical systems, High Line and Base. The High Line utilizes a Central Timer Module (CTM) to provide the body features listed below. The CTM was designed to reduce cost, wiring complexity, and improve the system reliable. The CTM interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of information between modules and diagnostic capability using the DRB III. The CTM equipped vehicles can be identified by the sound of a Key-In Ignition CHIME. The Base AB RAM VAN body system is composed of individual modules. Because the stand-alone modules do not communicate on the CCD Bus, they cannot be diagnosed using the DRB. For concerns about the BASE AB VAN, refer to the appropriate service procedures. The Base version can be identified by the sound of the Key-In Ignition BUZZER. The CTM provides the following features: CCD Bus Communication - Chime - Courtesy Lamp Controls/Illuminated Entry - Enhanced Accident Response - Intermittent Wiper Delay - Power Door Locks W/RKE - Remote Keyless Entry (RKE) - Speed Sensitive Intermittent Wipers - Vehicle Theft Security System (VTSS) The module is located on the left center instrument panel support. It contains a white 18-way and a green 14-way connector.

The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for gauge problems and tell tale warnings. The CTM chime functions will have priority over the MIC chime requests. There are two chime rates, Low; 50 chimes per minute for reminders and High; 180 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the driver door is open or the headlights are left ON. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for the key-in, and headlamp warning, as long as the drivers door is open. The seat belt warning chime is activated for 4 to 6 seconds , and all other chime conditions will activate the chime once at the same time the warning light ON the cluster is illuminated. The chime will sound for the following conditions: High rate Key in Warning ignition off, key in ignition, driver's door open - Ignition off, headlamps ON, driver's door open Low rate Seat belt warning - 6 seconds after key on (6 to 8 chimes) or until seatbelt is buckled - Airbag lamp illuminated (3 times after prove-out) - ABS lamp illuminated (2 chimes after prove-out if equipped) - Check engine lamp illuminated (2 chimes after prove-out) - Check gauges lamp illuminated (2 chimes) - Engine Temp High - when gauge enters red zone (2 chimes) - Low fuel - when fuel level reaches 1/8 tank (2 chimes) - Low washer fluid (2 chimes) - Transmission Temperature High (2 chimes) If the ignition switch is turned to the RUN/START position and the driver's door is closed, then opened, the warning chime is defeated. This allows the doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the OFF position, then normal function will be restored. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 227 Body Control Module: Description and Operation Airbag System Description AIRBAG SYSTEM The Airbag Control Module (ACM) is secured to a bracket on the floor panel below the drivers seat.

The ACM system logic includes On-Board Diagnostics (OBD) capability, and communicates with the instrument cluster circuitry on the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor in the ACM monitors the impact sensor signal and the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster on the CCD data bus to turn on the airbag indicator lamp. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbag system components. Only one impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags, for one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. The airbag warning lamp is the only point at which the customer can observe "symptoms" of a system malfunction, Whenever the ignition key is turned to the RUN or START position, the MIC performs a lamp check by turning the AIRBAG warning lamp ON for 6-8 seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the system or the MIC lamp circuit may be internally shorted to ground. If the lamp comes ON and stays ON for a period longer than 6-8 seconds then goes OFF, there is usually an intermittent problem in the system. The MIC monitors the airbag warning lamp and seat belt warning lamp during the bulb check for a defective bulb or lamp driver circuit. The MIC tests the airbag lamp during the cluster bulb check and substitutes the seat belt lamp if the airbag lamp is defective. If the airbag lamp is defective the MIC will turn the seat belt light ON and OFF approximately 30 times to warn the driver that the airbag lamp is defective. The lamp status is sent to the ACM continuously via a CCD bus message. The seat belt lamp acts as a backup in the event that the AIRBAG lamp is defective. This information is sent to the ACM continuously via a CCD bus message. Perform the WARNING LAMP BULB OR DRIVER procedure in this book to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated with no active DTC's The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. Service and general information labels about the airbag system can be found on the driver's sun visor, the glove box door, and in the engine compartment. WARNING: FAILURE TO HAVE THE AIRBAG SYSTEM PROPERLY SERVICED BY AN AUTHORIZED DEALER MAY LEAD TO POSSIBLE INJURY IN THE EVENT OF AN ACCIDENT. Driver Airbag Module (DAB) DRIVER AIRBAG MODULE (DAB) The airbag protection trim cover is the most visible part of the driver side airbag system. The module is mounted directly to the steering wheel. Located under the trim cover are the horn switch, the airbag cushion, and the airbag cushion supporting components. The airbag module includes a Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 228 housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator seals the hole in the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. The protective trim cover is fitted to the front of the airbag module and forms a decorative cover in the center of the steering wheel. Upon airbag deployment, this cover will split at a predetermined breakout line. THE AIRBAG MODULE INFLATOR ASSEMBLY CONTAINS SODIUM AZIDE AND POTASSIUM NITRATE. THESE MATERIALS ARE POISONOUS AND EXTREMELY FLAMMABLE. CONTACT WITH ACID, WATER, OR HEAVY METALS MAY PRODUCE HARMFUL AND IRRITATING GASES (SODIUM HYDROXIDE IS FORMED IN THE PRESENCE OF MOISTURE) OR COMBUSTIBLE COMPOUNDS, IN ADDITION, THE PASSENGER AIRBAG MODULE CONTAINS ARGON GAS PRESSURIZED TO OVER 2500 PSI. DO NOT ATTEMPT TO DISMANTLE AN AIRBAG MODULE OR TAMPER WITH ITS INFLATOR. DO NOT PUNCTURE, INCINERATE, OR BRING INTO CONTACT WITH ELECTRICITY DO NOT STORE AT TEMPERATURE EXCEEDING 93°C (200°F). Clockspring CLOCKSPRING The clockspring is mounted on the steering column behind the steering wheel. This assembly consists of a plastic housing which contains a flat, ribbon-like, electrically conductive tape that winds and unwinds with the steering wheel rotation. The clockspring is used to maintain a continuous electrical circuit between the instrument panel wire harness and the driver side airbag module, the horn switch, and the vehicle speed control switches on vehicles that are so equipped. The clockspring must be properly centered when it is installed on the steering column following any service removal, or it will be damaged. The clockspring cannot be repaired it must be replaced. Passenger Airbag Module (PAB) PASSENGER AIRBAG MODULE (PAB) The airbag door in the instrument panel top cover above the glove box is the most visible part of the passenger side airbag system. Located under the airbag door is the airbag cushion and it's supporting components. The airbag module includes a housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator includes a small canister of highly compressed argon gas. The inflator seals the hold in the airbag cushion so it can discharge the compressed gas it contains directly into the cushion when supplied with the proper electrical signal. The airbag door has a living hinge at the top, which is secured to the instrument panel top cover. The door also has predetermined breakout lines concealed beneath its decorative cover. Upon airbag deployment the airbag door will split at the breakout lines and the door will pivot out of the way. The airbag module is secured at the bottom to the steel structural base of the instrument panel above the glove box opening. The airbag door is serviced as a unit with the passenger side airbag module, and includes the two passenger heating and air conditioning panel outlet housings. Following an airbag deployment, the airbag module and the instrument panel assembly must be replaced. Passenger Airbag On/Off Switch PASSENGER AIRBAG ON/OFF SWITCH The passenger side airbag ON/OFF switch is located on the instrument panel. To de-activate the passenger side airbag, turn the key actuator switch from the horizontal position to a slanted position (pointing to the "OFF" light indicator), approximately 45 degrees clockwise from the "ON" position. Rotating the key actuator switch 45 degrees clockwise, remove the key completely from the switch and verify that the switch actuator hole stays in the new position (45 degrees clockwise from horizontal). The switch is spring loaded to the "ON" position. It will return to the "ON" position unless you remove the key. When the IGNITION in ON, this procedure will illuminate the "OFF" light indicator on the passenger airbag ON/OFF switch. To re-enable the passenger side airbag, reverse the procedure above so that the key switch actuator is returned to a horizontal position. NOTE: DO NOT TURN IGNITION ON WITH KEY IN SWITCH. DO NOT TURN SWITCH WITH IGNITION ON. DO NOT LEAVE KEY IN SWITCH. THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG ON/OFF SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE ON/OFF KEY CYLINDER. The ON/OFF switch cannot be adjusted or repaired and, if faulty or damaged, the ON/OFF switch must be replaced.

Interior Lighting INTERIOR LIGHTING The illuminated Entry system consist of a maximum of three dome lamps which are located in the front, middle and rear of the head liner. While the vehicle is off the illuminated entry feature can be activated in the following ways. Whenever a door is opened - When the vehicle is unlocked with a key - When the CTM receives a valid unlock signal from the RKE transmitter The illuminated entry will remain ON for 30 seconds after the last door is closed, turn OFF immediately after ignition is turned ON, or turn OFF when the CTM receives a LOCK message from the RKE transmitter. 15 Minute Illumination Timeout If the ignition is OFF and either front door is open, interior illumination will terminate after 15 minutes. If either front door is open and the ignition is turned in the RUN or ACCESSORY position, interior illumination will continue until the ignition is turned OFF. Once the ignition is OFF, if either front door remains open, the 15 minute interior illumination timeout will begin. Note: This timeout feature does not apply to either auxiliary door or the dome lamp switch which are hardwired to the courtesy lamps. The auxiliary door switches are also wired to the CTM to operate illuminated entry. Central Timer Module CENTRAL TIMER MODULE (CTM) The AB RAM VAN has two different body electrical systems, High Line and Base. The High Line utilizes a Central Timer Module (CTM) to provide the body features listed below. The CTM was designed to reduce cost, wiring complexity, and improve the system reliable. The CTM interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of information between modules and diagnostic capability using the DRB III. The CTM equipped vehicles can be identified by the sound of a Key-In Ignition CHIME. The Base AB RAM VAN body system is composed of individual modules. Because the stand-alone modules do not communicate on the CCD Bus, they cannot be diagnosed using the DRB. For concerns about the BASE AB VAN, refer to the appropriate service procedures. The Base version can be identified by the sound of the Key-In Ignition BUZZER. The CTM provides the following features: CCD Bus Communication - Chime - Courtesy Lamp Controls/Illuminated Entry - Enhanced Accident Response - Intermittent Wiper Delay - Power Door Locks W/RKE - Remote Keyless Entry (RKE) - Speed Sensitive Intermittent Wipers - Vehicle Theft Security System (VTSS) The module is located on the left center instrument panel support. It contains a white 18-way and a green 14-way connector. Central Timer Module Diagnostic Trouble Codes Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure Chime System Chime System The chime system is build into the CTM. The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for gauge problems and tell tale warnings. The CTM chime functions will have priority over the MIC chime requests. There are two chime rates, Low; 50 chimes per minute for reminders and High; 180 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the driver door is open or the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 230 headlights are left ON. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for the key-in, and headlamp warning, as long as the drivers door is open. The seat belt warning chime is activated for 4 to 6 seconds , and all other chime conditions will activate the chime once at the same time the warning light ON the cluster is illuminated. The chime will sound for the following conditions: High rate Key in Warning ignition off, key in ignition, driver's door open - Ignition off, headlamps ON, driver's door open Low rate Seat belt warning - 6 seconds after key on (6 to 8 chimes) or until seatbelt is buckled - Airbag lamp illuminated (3 times after prove-out) - ABS lamp illuminated (2 chimes after prove-out if equipped) - Check engine lamp illuminated (2 chimes after prove-out) - Check gauges lamp illuminated (2 chimes) - Engine Temp High - when gauge enters red zone (2 chimes) - Low fuel - when fuel level reaches 1/8 tank (2 chimes) - Low washer fluid (2 chimes) - Transmission Temperature High (2 chimes) If the ignition switch is turned to the RUN/START position and the driver's door is closed, then opened, the warning chime is defeated. This allows the doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the OFF position, then normal function will be restored. Description and Functional Operation DESCRIPTION AND FUNCTIONAL OPERATION The body system on the 1999 AB HIGH LINE consists of three modules that communicate over the CCD bus (Chrysler Collision Detection multiplex system). There are two additional modules, the Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are performed through the Serial Communication Interface of SCI, the same as previous years. All of the information about the functioning of all the system is organized, controlled, and communicated by (CCD Bus). Through the CCD bus, information about the operation of vehicle components and circuits is relayed quickly to the appropriate module(s). All modules receive all the information transmitted on the bus even though a module may not require all the information to perform it's function. It will only respond to messages "addressed" to it through a binary coding process. This method of data transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. DRB III Error Messages and Blank Screen DRB III ERROR MESSAGES AND BLANK SCREEN Under normal operation, the DRB will display one of only two error messages: User-Requested WARM Boot or - User-Requested COLD Boot If the DRB should display any other error message, record the entire display and call the MDS Hotline, or call for information and assistance at 1-800-825-8737. This is a sample of such an error message display: ver: 2.14 date: 26 Jul93 file: key_itf.cc date: Jul 26 1993 line: 548 err: Ox1 User-Requested COLD Boot Press MORE to switch between this display and the application screen. Press F4 when done noting information. DRB III Does Not Power Up (Blank Screen) If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (Data Link Connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, and inoperative DRB may be the result of a faulty cable or vehicle wiring. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 231 DRB III Scan Tool Display Is Not Visible Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition. Enhanced Accident Response (Highline CTM Only) ENHANCED ACCIDENT RESPONSE (Highline Only) If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The interior lights will be turned ON 10 seconds after getting zero speed message on the CCD bus. In addition to unlocking the doors, the lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "OFF" position, normal operation will resume. Diagnostics DIAGNOSTICS Gauges The instrument cluster will not store any DTC's. Because the engine controller PCM gathers all the gauge information and sends it to the cluster via the bus, it is the controller's responsibility to monitor these inputs and store DTC's for them. For this reason the first item to be checked regarding a gauge problem (except oil pressure) should be the engine controller for any DTC's relating to the gauge in question. There are DTC's associated with all the gauges except for the oil pressure gauge. When diagnosing gauges, the input that is used for gauge message (fuel level sender for example) must be valid. Because of OBD II requirements, most of the information used for monitoring the OBD II system happens to be the same information used by the controller to formulate the gauge bus messages. OBD II requirement state that the fuel level sender must be checked for rationality. This includes determining if the sending unit voltage is too high or too low or if the voltage hasn't changed over time. If the PCM has determined that the sender information isn't valid, it will send a diagnostic trouble code. The presence or absence of the fuel level sending code in the PCM is an important factor to determine whether a fuel gauge problem is in the sending unit or the cluster. The same situation is used in all cluster diagnostics related to gauge operation with the exception of the oil pressure gauge. OBD II requirements do not include oil pressure monitoring. Therefore, oil pressure diagnostic would dictate that a mechanical oil pressure gauge be attached to the engine for absolute verification of oil pressure readings. Hard Wired Lamps The cluster contains several hard wired lamps described earlier. The lamps are set up in two configurations. Either the cluster supplies power and ground is supplied by the circuit being monitored or the lamp is supplied ground by the cluster and power comes from a module or other device. Refer to the schematic for the specific details on the lamp in question. Verification of the bulb filament may be required in cases of an inoperative lamp. This will require removal of the cluster and bulb in question. NOTE: THE BRAKE, TRANS TEMP, CHECK GAUGES, SEAT BELTS AND AIRBAG WARNING LAMPS ARE LED'S, ALL OTHER ARE BULBS. IF ANY LED'S ARE DEFECTIVE,THE INSTRUMENT CLUSTER MUST BE REPLACED. CCD Controlled Lamps The cluster contains several CCD controlled lamps as described earlier. These lamps are part of the diagnostic self-test. When entering the self-test mode, operation of these lamps can be observed. If the bulb fails to operate during the self-test and the bulb filament is good, the cluster assembly will need to be replaced. NOTE: A FLASHING SEAT BELT LAMP INDICATES THAT THE AIRBAG WARNING LAMP IS NOT OPERATING PROPERLY. Mechanical Instrument Cluster Description MECHANICAL INSTRUMENT CLUSTER (MIC) Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 232 The Ram Van uses a standard MIC in all of it's U.S. vehicles. The cluster has 5 gauges and 15 indicator lamps. The gauges are positioned with information received over the CCD bus. Some of the indicator lamps are hardwired and the cluster using CCD bus information controls some. The MIC is hardwired to the CTM to provide the warning lamp announcement chimes. There is a self-test available for the cluster that will actuate all the gauges to their calibration points. The self test will not run if the cluster sees engine RPM or vehicle speed. The test will light all CCD controlled lamps for verification of lamp operation. It also forces the odometer Liquid Crystal Display (LCD) to perform a segment check. The self test routine can be entered by pressing and holding the trip reset button while rotating the ignition key from the OFF position to the ON position. When the word "check" appears, release the button and the test will continue. The cluster will provide bus bias termination and the engine controller provides a second termination. If the cluster is disconnected, the bus will not be biased. The cluster will be serviced as an assembly. There will be limited parts available, bulbs and sockets, the front lens, the trip odometer system cover and the rear cover assembly. No internal parts of the cluster will be serviceable. Normal Operation At key ON, the cluster will light the low fuel, seat belt, check gauges, and airbag. As the key is turned farther towards the start position, the check engine, ABS (if equipped) and brake warning lamp will illuminate. The liquid crystal display (LCD) will indicate the mileage stored inside the cluster. If there is a bus failure and the cluster cannot receive distance pulses from the engine controller, the cluster will display the last mileage stored until the ignition is turned OFF. If the cluster is receiving bus messages but is unable to display odometer information because of an internal failure, the odometer display will be blank. Dimming is handled by the potentiometer that controls instrumentation illumination. Lamps (Hardwired) The following lamps are hardwired in the cluster and are not part of the self-test. High Beam - Left Turn Signal - Right Turn Signal - Brake (comes ON during self-test) - Low Wash (comes during self-test) - Seat Belt (comes ON during self-test) Lamps (CCD) The cluster via CCD messages controls the following lamps. They are actuated during the self-test procedure. ABS lamps - Airbag - Check Engine - Check Gauges - Cruise Control Lamp - Security - Trans Temp - O/D OFF - Low Fuel Warning - Internally controlled by the cluster; not CCD NOTE: THE TURN SIGNALS, HIGH BEAM INDICATOR, SEAT BELT WARNING LAMP,LOW WASHER WARNING LAMP, AND BRAKE WARNING LAMP ARE HARDWIRED TO THE CLUSTER. Power Door Lock System POWER DOOR LOCKS The CTM controls the door lock actuation assemblies to handle locking and unlocking with the interior door lock switches or the RKE transmitter (key fob). There is also a door lock inhibit feature that prevents the power locking of the doors if the key is in the ignition or the headlamps are ON and the left front door is open. However, the doors can still be locked using the RKE transmitter which allows the engine to run for warm up purposes. Automatic (Rolling) Door Locks When the doors are closed and the vehicle speed exceeds 15 MPH due to engine power (not just rolling) and all doors are closed, the CTM will lock the doors. The vehicle is shipped with the automatic door lock feature disabled, but may be enabled using the DRB. Door Lock Delay If the CTM receives a signal to lock the doors and one or both of the auxiliary doors (side or rear) are open, the front doors will still lock. Five seconds after both of the auxiliary door are closed, the CTM will recycle the lock function. Remote Keyless Entry The CTM is compatible with a two button TRW RKE transmitter (keyfob). Two pre-programmed transmitters will be supplied with each vehicle. The CTM is capable of retaining up to four transmitters which can be programmed using the DRB. When a signal encoded with the correct vehicle access code is received and contains a valid message, the CTM will activate the corresponding relay to lock or unlock the doors. When an unlock Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 233 message is sent, all the doors will unlock, the VTSS will disarm and the illuminated entry will be activated. When a lock message is sent and all the doors are closed, all the doors will lock, the VTSS arming sequence will begin and the illuminated entry will turn OFF. Horn chirp When the doors are locked using the transmitter, a horn chirp will sound to let the customer know the doors were locked. The vehicle will be shipped with this function disabled but may be enabled using the DRB. The duration of the horn chirp can also be changed using the DRB. Trouble Codes AIRBAG DIAGNOSTIC TROUBLE CODES Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists, diagnostic priority should be given to the active codes. Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the trouble codes. It is not necessary to perform all of the tests in this book to diagnose an individual code. Always begin by reading the diagnostic trouble codes using the DRB III. This will direct you to the specific test(s) that must be performed Active diagnostic trouble codes for the airbag system are not permanent and will change the moment the reason for the code is corrected. In certain test procedures within this , diagnostic trouble codes are used as a diagnostic tool. Active Codes The code becomes active as soon as the malfunction is detected or key-OFF, whichever occurs first. An active trouble code indicates an on-going malfunction. This means that the defect is currently there every time the airbag control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected. With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present. The seat belt lamp replaces the airbag lamp if the airbag lamp is defective. The seat belt lamp pulses ON and OFF 30 times if the airbag warning lamp is defective. Stored Codes Airbag codes are automatically stored in the ACM's memory as soon as the malfunction is detected. The exception is the "Loss of Ignition Run Only" code which is an active code only. A "stored" code indicates there was an active code present sometime. However, the code currently may not be present as an active code, although another active code could be. When a trouble code occurs, the airbag warning lamp illuminates for 12 seconds minimum (even if the problem existed for less than 12 seconds). The code is stored, along with the time in minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. The minimum time shown for any code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two minutes 13 seconds, for example, would be three minutes. If malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored code. If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the problem. In this case, the stored code can indicate an area to inspect. If no obvious problems are found, erase stored codes, and with the ignition "ON" wiggle the wire harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes periodically as you work through the system. This procedure may uncover a malfunction that is difficult to locate. Airbag Trouble Codes The Airbag Control Module may report any of the following diagnostic trouble codes. For the following codes, replace the Airbag Control Module (ACM) even if set intermittently: ACM ACCELEROMETER - ACM OUTPUT DRIVER CIRCUIT OPEN - ACM INTERNAL DIAGNOSTIC CODE # 1 - ACM INTERNAL DIAGNOSTIC CODE # 2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 234 - ACM STORED ENERGY - ACM OUTPUT DRIVER For these codes, refer to the appropriate diagnostic procedure: Cluster Message Mismatch Driver Squib Circuit Open Driver Squib Circuit Shorted Driver Squib Circuit Shorted to Battery Driver Squib Circuit Shorted to Ground Loss of Ignition Run Only Loss of Ignition Run/Start NO Cluster CCD Message No CCD Communication Passenger Squib Circuit Open Passenger Squib Circuit Shorted Passenger Squib Circuit Shorted to Battery Passenger Squib Circuit Shorted to Ground Warning Lamp Open/Shorted Vehicle Communication VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the higher priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus -" (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a voltage divider network located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems use more than one. Some modules are capable of biasing and terminating the bus by themselves. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. Without termination, voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. In the 1999 Ram Van, the instrument cluster supplies bus bias and termination and the PCM supplies an additional point of termination. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLES ON-BOARD DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING.IF THERE IS A PROBLEM, REFER TO THE VEHICLE COMMUNICATION. Vehicle Theft Security System (VTSS) VEHICLE THEFT SECURITY SYSTEM (VTSS) The VTSS will monitor the states of the ignition, door lock signal, and all other doors to alert against unauthorized entry into the vehicle. The VTSS will be enabled at the assembly plant. To prevent arming of the VTSS during assembly and the shipping process, the vehicle must be started 20 times before the VTSS will operate properly. Arming the VTSS To arm the system, the ignition must be OFF and all doors must be closed and locked using either the power door lock switches or the RKE transmitter. Using a key or pressing the mechanical lock soldier will not initiate arming the VTSS. The delay lock feature will delay the arming process until all doors are closed. Once the VTSS begins to arm, the CTM will activate the security lamp output at a 1 Hz rate. During this process the arming process will terminate if the ignition is turned ON, if a door is opened, if the doors are unlocked using the door lock switch or the RKE transmitter, or if the front doors are unlocked using the key. After fifteen seconds of the arming process, the security lamp will go OFF and the VTSS will be armed. Once the vehicle is armed the ignition may be turned to the accessory position (to listen to radio, etc.) without triggering the alarm. The VTSS can only be disarmed using the key or the RKE transmitter. Triggering the VTSS Once the VTSS is armed, the alarm will trigger if any of the doors are opened or if the key is turned the Run/Start position. When triggered, the CTM will instruct the PCM to turn OFF the engine after two seconds and will pulse the horn and headlamps at a specified duty cycle and frequency. The audible (horn) warning will continue for three minutes then terminate. The visual (headlamps) warning will continue for fifteen additional minutes then terminate. The engine will continue to start and quit until the VTSS is disarmed. Tamper Alert If the VTSS was triggered during the last armed period, the next time it is disarmed the CTM will activate three horn chirps. To determine what caused the alarm to be tripped, using the DRB select "Theft Alarm" "Monitor Display" and observe: "Alarm Tripped by". This is a great tool to Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 235 use when a customer complains that the alarm went OFF and cannot determine what triggered it. Warnings WARNINGS Vehicle Damage Warnings Before disconnecting any control module, make sure the ignition is OFF. Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected. Road Testing A Complaint Vehicle Some complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic code or symptom condition. CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE REASSEMBLED DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB SCREEN WHILE IN MOTION.DO NOT HANG THE DRB FROM THE REAR VIEW MIRROR OR OPERATE IT YOURSELF.HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB. Wiper System WINDSHIELD WIPERS Feature Description The Ram Van equipped with a CTM will utilize speed sensitive intermittent wipe and wipe after wash function. The driver selects the Wiper function via a Steering Column mounted Stalk Switch. The Wiper system is operational whenever the ignition switch is in the Run or Accessory positions only (not during engine crank). The low and high speeds are controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as selected by the driver, and immediate wipe of the windshield takes place and the new delay interval is implemented. An Intermittent Wipe cycle consists of operating the Wipers in the Low Speed mode for one cycle, then executing a delay time. The delay time available to the driver is adjustable from 1/2 second to 18 seconds. Speed Sensitive Intermittent Wipe Operation Speed Intermittent Wipe is operational whenever the Ignition Switch is in either the RUN or ACCESSORY positions, and the voltage ON the CKT name input is greater than 4.5 VDC. The resistance selected by the stalk switch is used to set the delay time between wipe cycles. The Intermittent Wipe Delay Time is also adjusted based upon Vehicle Speed. When the Vehicle Speed is < 10 MPH then the driver selected Delay Time is doubled providing a range from 1 second to 36 seconds. When the vehicle speed is > 10 MPH then the driver selected Delay Time is not adjusted. An immediate Low Speed mode Wipe cycle will occur and a new Delay Time interval will start if the driver changes the current selected Delay Time to a shorter interval. The speed signal is provided to the CTM from the PCM over the CCD bus. Wipe after Wash Operation Wipe after Wash operation activates the Wiper system when the Wash button is pressed. Wiper after Wash operation is available while the wiper switch is OFF or in Intermittent mode, and operates the Wipers in a Low Speed continuous cycling mode while the Wash button is held on. After the Wash button is released, 2 additional complete cycles are performed at Low Speed. The Wiper system returns to the previous mode of operation following the completion of the additional Wipe cycles. Self Calibration A self calibration feature is used to eliminate performance variations due to tolerances in the resistances of the intermittent wiper switch. Following a power on reset, a default value is copied to a battery backed RAM memory location. If a valid resistance value greater than the current battery backed compensation value is measured during intermittent wiper operation, and it is present for 8 consecutive samples, the compensation value is replaced by the average of the compensation value and the new resistance value. This compensation value is used to calculate the intermittent wiper delay, using the following formula: Delay in seconds = 0.5 + 17.5* (resistance value/ compensation value) Three EEPROM locations have been provided to allow for optional calibration of the intermittent wipers. One location specifies a constant which will override the battery backed compensation value. The other locations specify constants which will override the default offset and slope used in converting resistance to time delay. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 236 Failed Wiper Park Switch A failed Wiper Park Switch is determined by the CTM "C1" PIN # 11 input remaining high for eight seconds when the wiper system is in intermittent mode. Once detected, a code flag will be set in the EEPROM fault record byte. Once the Failed Wiper Park Switch fault is set, the intermittent wiper function will not operate until a low is seen on the CTM "C1" PIN # 11 input with the ignition ON. The code flag may only be cleared manually using a DRB. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures Body Control Module: Symptom Related Diagnostic Procedures Chime Inoperative at All Times SYMPTOM * CHIME INOPERATIVE AT ALL TIMES POSSIBLE CAUSES - Chime inoperative at all times Chime Inoperative With Any Warning Lamp on SYMPTOM * CHIME INOPERATIVE WITH ANY WARNING LAMP ON POSSIBLE CAUSES - Tone request signal circuit open - Instrument cluster defective - Central Timer Module defective Chime Inoperative With Exterior Lamps On SYMPTOM * CHIME INOPERATIVE WITH EXTERIOR LAMPS POSSIBLE CAUSES - Driver door ajar switch status no change - Left door ajar switch circuit open Chime Inoperative With Key In Ignition & Driver Door Open SYMPTOM * CHIME INOPERATIVE WITH KEY IN IGNITION, DRIVER'S DOOR OPEN POSSIBLE CAUSES - Driver door switch status not changing - Key in ignition switch sense circuit open - Defective Central Timer Module - Ignition switch defective Chime Inoperative With Only One Warning Lamp SYMPTOM * CHIME INOPERATIVE WITH ONLY ONE WARNING LAMP POSSIBLE CAUSES - Oil pressure sensor defective - Oil pressure sense circuit open - Powertrain Control Module defective - Cooling system operation faulty - DRB not showing PCM active on Bus - DRB shows ECT sensor voltage too high - DRB shows ECT sensor voltage too low Chime Remains on With the Ignition on SYMPTOM * CHIME REMAINS ON WITH THE IGNITION ON POSSIBLE CAUSES - Chime staying ON with ignition ON - Tone request signal circuit short - Central Timer Module defective - Instrument cluster defective Chime Sounds With Driver's Door Open SYMPTOM * CHIME SOUNDS WITH DRIVER'S DOOR OPEN POSSIBLE CAUSES Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures > Page 239 - Chime sounds with key removed - Key in ignition switch sense circuit short - Left front door ajar switch sense circuit short - Driver door misaligned - Central Timer Module defective Courtesy Lamp Inoperative With Left Front Door SYMPTOM * COURTESY LAMPS INOPERATIVE FROM LEFT FRONT DOOR TEST NOTE This symptom is diagnosed using the test * OPEN DRIVER DOOR AJAR.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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.

To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 260 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 261 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 262 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 263 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated 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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 274 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 275 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 276 Powertrain Control Module: Connector Views Powertrain Control Module Connectors Powertrain Control Module C1 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 277 Powertrain Control Module C2 Powertrain Control Module C3 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Description and Operation > Engine Control Powertrain Control Module: Description and Operation Engine Control POWERTRAIN CONTROL MODULE Powertrain Control Module (PCM) The Powertrain Control Module (PCM) is located in the engine compartment.

The ACM contains an electronic microprocessor, an electronic impact sensor, an electromechanical safing sensor, and an energy storage capacitor. The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. OPERATION The microprocessor in the ACM contains the airbag system logic. The airbag system logic includes On-Board Diagnostics (OBD), and the ability to communicate with the instrument cluster circuitry over the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor continuously monitors all of the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster over the CCD data bus to turn on the airbag indicator lamp. Refer to instrument Cluster in the Instrument Panel Systems for more information on the airbag indicator lamp. One electronic impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate as signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbags. In addition to the electronic impact sensor, there is an electromechanical sensor within the ACM called a safing sensor. The safing sensor is a normally open series switch located in the airbag deployment circuit of the ACM. This sensor detects impact energy of a lesser magnitude than the electronic impact sensor, and must be closed in order for the airbags to deploy. The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags for up to one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact, if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Restraint Systems > Air Bag Control Module > Component Information > Specifications > Page 319 Air Bag Control Module: Service and Repair WARNING: - THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG.

The starter relay is located in the Power Distribution Center (PDC), in the engine compartment. See the fuse and relay layout label affixed to the inside surface of the PDC cover for starter relay identification and location. The starter relay is a International Standards Organization (ISO) micro-relay. Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal patterns and terminal functions. 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 starter relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION 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 the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Starting and Charging > Starter Relay > Component Information > Locations > Page 327 Starter Relay: Testing and Inspection STARTER RELAY Starter Relay The starter relay is located in the Power Distribution Center (PDC), in the engine compartment. Refer to the fuse and relay layout label affixed to the underside of the PDC cover for starter relay identification and location. 1. Remove the starter relay from the PDC. Refer to Starter Relay in the Replacement for the procedures. 2. A relay in the 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 the 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 the faulty relay 4. Connect a battery to terminals 85 and 86. There should now be continuity between terminals 30 and 87, and no continuity between terminals 87A and 30. If OK, perform the Relay Circuit Test that follows. If not OK, replace the 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 the open circuit to the fuse in the 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 the common feed terminal (30) in the energized position. This terminal supplies battery voltage to the starter solenoid field coils. There should be continuity between the cavity for relay terminal 87 and the starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair the open circuit to the starter solenoid as required. 4. The coil battery terminal (86) is connected to the electromagnet in the relay It is energized when the ignition switch is held in the START position. Check for battery voltage at the cavity for relay terminal 86 with the ignition switch in the START position, and no voltage when the ignition switch is released to the ON position. If OK, go to Step 5. If not OK, check for an open or short circuit to the ignition switch and repair, if required. If the circuit to the ignition switch is OK, refer to Ignition Switch and Key Lock Cylinder Diagnosis and Testing for testing of the ignition switch. 5. The coil ground terminal (85) is connected to the electromagnet in the relay. It is grounded through the park/neutral position switch only when the gearshift selector lever is in the Park or Neutral positions. Check for continuity to ground at the cavity for relay terminal 85. If not OK, check for an open or short circuit to the park/neutral position switch and repair, if required. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Starting and Charging > Starter Relay > Component Information > Locations > Page 328 Starter Relay: Service and Repair Power Distribution Center REMOVAL 1.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure. NOTE: WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION LEVEL.

In addition to low and high speed, the intermittent wipe system has a delay mode. Electronic circuitry within the intermittent wipe module is used to accomplish the wiper delay mode. The delay time selected by the driver has a range of from about one-half second to about eighteen seconds. The driver selects the length of the delay by placing the wiper (multi-function) switch knob in one of five different intermittent wipe detent positions. One of the detent positions sends a battery voltage signal to the intermittent wipe module, while the other four positions use resistors to provide progressively lower voltage signals to the module. If the washer knob is depressed while the wiper switch is in the Off position, the intermittent wipe module will operate the wiper motor for approximately three wipes and automatically turn off the motor. The intermittent wipe module is snap-fit onto a single blade-type mounting bracket located on the instrument panel reinforcement above the glove box opening. The intermittent wipe module cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Wiper and Washer Systems > Wiper Control Module > Component Information > Service Precautions > Page 359 Wiper Control Module: Testing and Inspection Intermittent Wiper Module Testing The intermittent wipe module is used on vehicles that are not equipped with the Vehicle Theft Security System (VTSS).

A sensor is mounted to each front steering knuckles. The third sensor is mounted on top of the rear axle differential housing. The sensor is a magnet coil that is mounted over a tone wheel front/exciter ring rear with an air gap between them. The sensors measure the wheel speed by monitoring the rotation of the tone wheels front/exciter ring rear. As the teeth of the tone wheels front/exciter ring rear move through the magnetic field of the sensor an AC voltage is generated. This signal frequency increases or decreases proportionally to the speed of the wheel. The Controller Antilock Brake (CAB) monitors these signals for changes in wheel deceleration. If the CAB detects a sudden wheel or wheels deceleration within a predetermined amount the CAB will activate the ABS system. CIRCUIT OPERATION The all wheel Anti-Lock Brake System (ABS) uses three wheel speed sensors; a single sensor for both rear wheels and individual sensors for the front wheels. The single sensor used for the rear wheels mounts on the top of the rear axle differential housing. Each sensor converts wheel speed into an electrical signal that is transmitted to the Controller Anti-Lock Brakes (CAB). A pair of twisted wires connect to each sensor and provide signals to the CAB. Circuits B6 and B7 provide signals to the CAB from the right front wheel speed sensor. Circuit B6, which provides the LOW signal, connects to cavity 15 of the CAB. Circuit B7 connects to cavity 2 of the CAB and provides the HIGH signal. Circuits B8 and B9 provide signals to the CAB from the left front wheel speed sensor. Circuit B8, which provides the LOW signal, connects to cavity 16 of the CAB. Circuit B9 connects to cavity 3 and provides the HIGH signal. Circuit B114 connects to cavity 14 of the CAB and to circuit B2 of the rear wheel speed sensor harness at the sensor connector. Circuit B113 connects to cavity 1 of the CAB and to circuit B1 at the rear wheel speed sensor harness connector. Circuit B114 provides the rear wheel speed sensor LOW input while circuit B113 provides the HIGH input. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Brakes and Traction Control > Wheel Speed Sensor > Component Information > Description and Operation > Four Wheel Antilock Brakes > Page 417 Wheel Speed Sensor: Description and Operation Rear Wheel Antilock Brakes The rear wheel speed sensor is mounted on the top of the rear axle differential. The sensor converts wheel speed into an electrical signal that is transmitted to the Rear Wheel Anti-Lock (RWAL) control module. Circuits B113 and B114, a pair of twisted wires connect to the sensor and provide signals to the RWAL control module. These circuits also connect to the rolls test connector used only during manufacture of the vehicle. Circuit B113 connects to cavity 14 of the RWAL control module and to circuit B1 of the wheel speed sensor harness. Circuit B114 connects to cavity 13 of the RWAL control module and circuit B2 of the sensor harness. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Brakes and Traction Control > Wheel Speed Sensor > Component Information > Service and Repair > Wheel Speed Sensor Replacement Wheel Speed Sensor: Service and Repair Wheel Speed Sensor Replacement Front REMOVAL 1.

The sensor provides an input voltage to the powertrain control module (PCM) relating coolant temperature. The PCM uses this input along with inputs from other sensors to determine injector pulse width and ignition timing. As coolant temperature varies, the coolant temperature sensor resistance will change. This change in resistance results in a different input voltage to the PCM. When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air-fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 431 Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection COOLANT TEMPERATURE SENSOR To perform a complete test of the engine coolant temperature sensor and its circuitry, refer to DRB scan tool and appropriate Powertrain Diagnostics Procedures.

The two switch modules are labeled: ON/OFF SET, RESUME/ACCEL, CANCEL and COAST. Refer to the owner's manual for more information on speed control switch functions and setting procedures. The individual switches cannot be repaired. If one individual switch fails, the switch module must be replaced. OPERATION Within the two switch modules, five momentary contact switches, supporting seven different speed control functions are used. The outputs from these switches are filtered into one input. The Powertrain Control Module (PCM) determines which output has been applied through resistive multiplexing. The input circuit voltage is measured by the PCM to determine which switch function has been selected. A speed control indicator lamp, located on the instrument panel cluster is energized by the PCM via the CCD Bus. This occurs when speed control system power has been turned ON, and the engine is running. SPEED CONTROL SWITCHES - PCM INPUT Six different speed control functions, using three momentary contact switches, are monitored through this multiplexed input. The resistance monitored at this input, in combination with the length of time the PCM measures the resistance, determines which switch feature has been selected. The four switches are: ON/OFF, SET/COAST, CANCEL and RESUME/ACCELERATE. Refer to Vehicle Speed Control System for further speed control information. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Cruise Control > Cruise Control Switch > Component Information > Specifications > Page 444 Cruise Control Switch: Service and Repair SPEED CONTROL SWITCHES REMOVAL WARNING: BEFORE BEGINNING ANY AIRBAG SYSTEM COMPONENT REMOVAL OR INSTALLATION, REMOVE AND ISOLATE THE NEGATIVE (-) CABLE(S) FROM THE BATTERY.

When the fin sensing cycling clutch switch sees a temperature input below about 1.6° C (35° F), it signals the PCM to cycle the compressor OFF. When the temperature input reaches above about 3.9° C (39° F), the switch signals the PCM to cycle the compressor back ON. The fin sensing cycling clutch switch can be accessed for service by removing the screws and carefully lifting the front of the top cover up from the heater-A/C housing. The fin sensing cycling clutch switch is a sealed unit and cannot be adjusted or repaired. If faulty or damaged, the switch must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - HVAC > Fin Sensing Cycling Clutch Switch <--> [Evaporator Temperature Sensor / Switch] > Component Information > Specifications > Page 474 Fin Sensing Cycling Clutch Switch: Testing and Inspection FIN SENSING CYCLING CLUTCH SWITCH Before testing the fin sensing cycling clutch switch, verify that the refrigerant system has the correct refrigerant charge. Also check that both the low and high pressure cut-off switches are functional, and confirm that the compressor clutch is operational. 1. Turn the ignition switch in the ON position. Place the heater-A/C mode control switch in any A/C position. Check for battery voltage at the fused ignition switch output (Run/Start) circuit cavity of the fin sensing cycling clutch switch wire harness connector. If OK, go to Step 2. If not OK, repair the open circuit to the fuse in the junction block as required. 2. With the ambient temperature between 20 to 30° C (68 to 90° F), start the engine and run the air conditioning system. The compressor clutch should cycle on and off two to three times per minute. If the clutch fails to cycle at this rate in these temperatures, replace the faulty fin sensing cycling clutch switch. NOTE: If the ambient temperature is above 32° C (90° F) the compressor clutch may stay engaged and not cycle due to the high heat load. This condition is normal. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - HVAC > Fin Sensing Cycling Clutch Switch <--> [Evaporator Temperature Sensor / Switch] > Component Information > Specifications > Page 475 Fin Sensing Cycling Clutch Switch: Service and Repair FIN SENSING CYCLING CLUTCH SWITCH Fin Sensing Cycling Clutch Switch Remove/Install REMOVAL 1.

The fuel pump module is located inside of fuel tank. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Specifications > Page 504 Fuel Gauge Sender: Description and Operation FUEL PUMP MODULE Top View of Fuel Pump Module Fuel Pump Module Components (Typical Pump Module Shown) The fuel pump module on all models is installed in the top of the fuel tank. The fuel pump module contains the following components: - A combination fuel filter/fuel pressure regulator - Electric fuel pump - Fuel pump reservoir - A separate fuel pick-up filter (strainer) - Fuel gauge sending unit (fuel level sensor) - Fuel supply line connection at filter/regulator - A plastic threaded locknut to retain pump module to fuel tank - A gasket between tank flange and module The fuel gauge sending unit (fuel level sensor), and pick-up filter (at bottom of module) may be serviced separately. If the electrical fuel pump requires service, the entire fuel pump module must be replaced. The fuel filter/fuel pressure regulator may be serviced separately. Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for additional information. FUEL GAUGE SENDING UNIT 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). The resistor track is used to send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for OBD II emission requirements. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Specifications > Page 505 For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and arm move down. This increases the sending unit resistance causing the fuel gauge to read empty. After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading. For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the sending unit to the PCM 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 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 Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Specifications > Page 506 Fuel Gauge Sender: Testing and Inspection The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down, electrical resistance will change. Refer to Instrument Panel and Gauges for Fuel Gauge testing. To test the gauge sending unit only, it must be removed from vehicle. The unit is part of the fuel pump module. Refer to Fuel Pump Module Removal/ Installation for procedures. Measure the resistance across the sending unit terminals. With float in up position, resistance should be 20 ohms ± 6 ohms. With float in down position, resistance should be 22 ohms ± 6 ohms. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Service and Repair > Fuel Gauge Sending Unit Replacement Fuel Gauge Sender: Service and Repair Fuel Gauge Sending Unit Replacement Fuel Gauge Sending Unit Location-Typical Module The fuel gauge sending unit (fuel level sensor) and float assembly is located on the side of fuel pump module.

DESCRIPTION The plunger type brake lamp switch is mounted on a bracket attached to the brake pedal support. CAUTION: The switch can only be adjusted during initial installation. If the switch is not adjusted properly a new switch must be installed. OPERATION Vehicles equipped with the speed control option use a dual function stop lamp switch. The PCM monitors the state of the dual function stop lamp switch. BRAKE SWITCH-PCM INPUT When the brake light switch is activated, the Powertrain Control Module (PCM) receives an input indicating that the brakes are being applied. After receiving this input, the PCM maintains idle speed to a scheduled rpm through control of the Idle Air Control (IAC) motor. The brake switch input is also used to disable vent and vacuum solenoid output signals to the speed control servo. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Lighting and Horns > Brake Light Switch > Component Information > Technical Service Bulletins > Page 526 Brake Light Switch: Testing and Inspection The content of this article reflects changes called for in TSB 26-12-98.

The switch consists of two plastic membranes, one that is flat and one that is slightly convex. These two membranes are secured to each other around the perimeter. Inside the switch, the centers of the facing surfaces of these membranes each has a grid made with an electrically conductive material applied to it. One of the grids is connected to a circuit that provides it with continuity to ground at all times. The grid of the other membrane is connected to the horn relay control circuit. The steering wheel and steering column must be properly grounded in order for the horn switch to function properly. The horn switch is only serviced as a part of the driver side airbag module trim cover. If the horn switch is damaged or faulty, or if the driver side airbag is deployed, the driver side airbag module trim cover and horn switch must be replaced as a unit. OPERATION When the center area of the driver side airbag trim cover is depressed, the electrically conductive grids on the facing surfaces of the horn switch membranes contact each other, closing the switch circuit. The completed horn switch circuit provides a ground for the control coil side of the horn relay, which activates the relay. When the horn switch is released, the resistive tension of the convex membrane separates the two electrically conductive grids and opens the switch circuit. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Lighting and Horns > Horn Switch > Component Information > Service Precautions > Page 560 Horn Switch: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

OPERATION The multi-function switch control stalk that extends from the left side of the steering column just below the steering wheel is moved up or down to activate the turn signal switch. When the control stalk is moved in the upward direction, the right turn signal switch circuitry is activated; and, when the control stalk is moved in the downward direction, the left turn signal switch circuitry is activated. 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 multi-function switch control stalk is released. When the turn signal switch is in a detent position, it is turned off by a turn signal cancel cam located on the steering column upper shaft below the shaft lock shield and the clockspring mechanism. Turning the steering wheel causes the cancel cam lobes to contact a cancel actuator in the multi-function switch, and the turn signal switch automatically returns to the off position. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Lighting and Horns > Turn Signal Switch > Component Information > Specifications > Page 566 Turn Signal Switch: Testing and Inspection The turn signal switch and the hazard warning switch are integral to the multi-function switch.

The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Refer to Camshaft Position Sensor, Ignition System for more information. CAMSHAFT POSITION SENSOR The camshaft position sensor is located in the distributor on all engines. The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events.

The sensors produce voltages from 0 to 1 volt, depending upon the oxygen content of the exhaust gas in the exhaust manifold. When a large amount of oxygen is present (caused by a lean air/fuel mixture), the sensors produces a low voltage. When there is a lesser amount present (rich air/fuel mixture) it produces a higher voltage. By monitoring the oxygen content and converting it to electrical voltage, the sensors act as a rich-lean switch. The oxygen sensors are equipped with a heating element that keeps the sensors at proper operating temperature during all operating modes. Maintaining correct sensor temperature at all times allows the system to enter into closed loop operation sooner. Also, it allows the system to remain in closed loop operation during periods of extended idle. In closed Loop operation, the PCM monitors the O2S sensor input (along with other inputs) and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values and inputs from other sensors. The Automatic Shutdown (ASD) relay supplies battery voltage to both the upstream and downstream heated oxygen sensors. The oxygen sensors are equipped with a heating element The heating elements reduce the time required for the sensors to reach operating temperature. UPSTREAM HEATED OXYGEN SENSOR Heated Oxygen Sensors The upstream O2S sensor is located in the inlet end of the catalytic converter. It provides an input voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The PCM uses this information to fine tune the air/fuel ratio by adjusting injector pulse width. DOWNSTREAM HEATED OXYGEN SENSOR The downstream heated oxygen sensor threads into the outlet end of the catalytic convertor. The downstream heated oxygen sensor input is used to detect catalytic convertor deterioration. As the convertor deteriorates, the input from the downstream sensor begins to match the upstream sensor input except for a slight time delay. By comparing the downstream heated oxygen sensor input to the input from the upstream sensor, the PCM calculates catalytic convertor efficiency. When the catalytic converter efficiency drops below emission standards, the PCM stores a diagnostic trouble code and illuminates the Malfunction Indicator Lamp (MIL). For more information., refer to Emission Control Systems. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Locations > Page 643 Oxygen Sensor: Testing and Inspection To perform a complete test of the O2S sensors and their circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures. To test the O2S sensors only, refer to the following: Oxygen Sensor Location The upstream O2S sensor is located on the inlet end of the catalytic converter. The downstream O2S sensor is located on the outlet end of the catalytic converter. Each O2S heating element can be tested with an ohmmeter as follows: Disconnect the O2S sensor connector. Connect the ohmmeter test leads across the white wire terminals of the sensor connector. Resistance should be between 4.5 ± 0.5 ohms and 7 ohms. Replace the sensor if the ohmmeter displays an infinity (open) reading. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Locations > Page 644 Oxygen Sensor: Service and Repair UPSTREAM OXYGEN SENSOR Oxygen Sensor Location The O2S sensors are located at the inlet and outlet ends of the catalytic converter.

The TPS is a variable resistor that provides the powertrain control module (PCM) with an input signal (voltage) that represents throttle blade position. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Specifications > Page 651 Throttle Position Sensor: Testing and Inspection To perform a complete test of the TPS and its circuitry; refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures. To test the TPS only, refer to the following: The TPS can be tested with a digital voltmeter. The center terminal of the TPS is the output terminal. With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT). At idle, TPS output voltage should must be greater than 0.26 volts and less than 0.95 volts. At wide open throttle, TPS output voltage must be less than 4.49 volts. The output voltage should increase gradually as the throttle plate is slowly opened from idle to WOT. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Specifications > Page 652 Throttle Position Sensor: Service and Repair THROTTLE POSITION SENSOR (TPS) MAP Sensor, TP Sensor, IAC Motor The TPS is located on the side of the throttle body.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 665 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 666 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 667 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 668 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 669 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated 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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 680 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 681 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is used to check for voltage on a circuit.

The TPS is a variable resistor that provides the powertrain control module (PCM) with an input signal (voltage) that represents throttle blade position. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Specifications > Page 694 Throttle Position Sensor: Testing and Inspection To perform a complete test of the TPS and its circuitry; refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures. To test the TPS only, refer to the following: The TPS can be tested with a digital voltmeter. The center terminal of the TPS is the output terminal. With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT). At idle, TPS output voltage should must be greater than 0.26 volts and less than 0.95 volts. At wide open throttle, TPS output voltage must be less than 4.49 volts. The output voltage should increase gradually as the throttle plate is slowly opened from idle to WOT. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Specifications > Page 695 Throttle Position Sensor: Service and Repair THROTTLE POSITION SENSOR (TPS) MAP Sensor, TP Sensor, IAC Motor The TPS is located on the side of the throttle body.

The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Refer to Camshaft Position Sensor, Ignition System for more information. CAMSHAFT POSITION SENSOR The camshaft position sensor is located in the distributor on all engines. The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal 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. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Locations > Page 703 Camshaft Position Sensor: Service and Repair CAMSHAFT POSITION SENSOR Camshaft Position Sensor The camshaft position sensor is located in the distributor.

This switch, which is located on the instrument panel, allows the passenger side airbag system to be disabled when certain child restraint devices are being used in the right front seating position. The passenger side airbag on/off switch is equipped with a key actuator so that the switch position can only be changed using an ignition key. When the ignition switch is in the On position and the passenger side airbag system is disabled, a Light-Emitting Diode (LED) illuminates an Off indicator lamp on the face plate of the switch. The passenger side airbag on/off switch cannot be adjusted or repaired and, if faulty or damaged, the switch assembly must be replaced. Operation To actuate the passenger side airbag on/off switch, insert the ignition key in the switch key actuator. The switch key actuator is then rotated with the ignition key to its clockwise stop (the key actuator slot will be aligned with the Off indicator lamp) to disable the passenger side airbag system. When the switch key actuator is rotated with the ignition key to its counterclockwise stop (the key actuator slot will be in a vertical position), the Off indicator lamp will be extinguished and the passenger side airbag system will be enabled. The ON/OFF switch cannot be adjusted or repaired and, if faulty or damaged, the ON/OFF switch must be replaced. WARNING: THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER SIDE AIRBAG ON/OFF SWITCH KEY ACTUATOR AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE SWITCH KEY ACTUATOR.

The temperature readings are used to control engagement of the fourth gear overdrive clutch, the converter clutch, and governor pressure. Normal resistance value for the thermistor at room temperature is approximately 1000 ohms. The PCM prevents engagement of the converter clutch and overdrive clutch, when fluid temperature is below approximately 10 °C (50 °F). If fluid temperature exceeds 126 °C (260 °F), the PCM causes a 4-3 downshift and engage the converter clutch. Engagement is according to the third gear converter clutch engagement schedule. The overdrive OFF lamp in the instrument panel illuminates when the shift back to third occurs. The transmission will not allow fourth gear operation until fluid temperature decreases to approximately 110 °C (230 °F). The thermistor is part of the governor pressure sensor assembly and is immersed in transmission fluid at all times. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation > Page 791 Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - PCM Input TRANSMISSION TEMPERATURE SENSOR - PCM INPUT This input is used in the shift operation for speed electronic transmissions only.

MODELS: 1998-2001 (AB) Ram Van/Wagon SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight steering corrections are necessary to be able to keep the vehicle moving in a straight line. Steering wander can be created by a number of different conditions including but not limited to the following: ^ Non-factory installed options. ^ Tires or wheels of different size. ^ Aftermarket wheels. ^ Tires that have a belt that has shifted. ^ Incorrect tire pressure. ^ A vehicle that is carrying extra added weight (e.g. tool boxes). ^ Steering and/or suspension components that are worn or damaged. ^ Wheel bearings that are loose, worn, or damaged. ^ A vehicle that is not within alignment specifications. NOTE: UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER. The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering system components are functioning as designed and are not the root cause of steering wander. DIAGNOSIS: 1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to exceed the front or rear Gross Axle Weight Rating (GAWR). 2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to wander and should be replaced before continuing with the diagnosis. 3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove box). NOTE: TIRE PRESSURES ARE NORMALLY SET TO THE LIGHT LOAD SPECIFICATION WHEN PERFORMING STEERING WANDER DIAGNOSIS BUT, ONLY IF THE VEHICLE IS AT CURB OR LIGHT LOAD CONDITIONS. 4. Validate the customer's concern by test driving the vehicle on a smooth highway, free of road crown, ruts, speed bumps, or potholes. Drive the vehicle at speeds between 80 - 113 km/h (50 - 70 mph), preferably without cross wind conditions. If crosswind conditions are prevalent, drive the vehicle in both directions relative to the crosswind. Proceed to the next step if the vehicle exhibits a steering wander condition. NOTE: VEHICLES THAT DO NOT EXHIBIT A STEERING WANDER CONDITION DURING THE ROAD TEST MAY HAVE HAD THE CONDITION CORRECTED WITH STEPS 1-3 OR THE CONDITION MAY HAVE BEEN CAUSED BY ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, ETC.). 5. Raise the vehicle on an appropriate lift. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 823 6. Secure a dial indicator to the lower control arm. Position the dial indicator so that the tip of the indicator contacts the inside face of the rotor (Figure 1). 7. Place your hands at the top and bottom of the tire/wheel assembly and push the tire/wheel assembly inboard (Figure 2). Zero the dial indicator. With your hands at the top and bottom of the tire/wheel assembly, pull the tire/wheel assembly outboard (Figure 3). Record the dial indicator reading. Perform this procedure on both front wheel bearings and proceed to the next step if the wheel bearing endplay exceeds 0.025 - 0.076 mm (0.001 - 0.003 in.). Proceed to Step 9 if wheel-bearing endplay on both front wheel bearings are within specifications. NOTE: WHEEL BEARING INSPECTION AND ADJUSTMENT IS ONLY REQUIRED ON WHEEL BEARINGS EXCEEDING 0.025 - 0.076 MM (0.001 - 0.003 IN.) ENDPLAY. 8. Remove the wheel bearing protective end cap, cotter pin, nut lock, nut, and washer from the spindle. Inspect the wheel bearings. If it is determined that wheel bearing replacement is necessary, refer to the appropriate Ram Van/Wagon Service Manual, Group 02, Wheel Bearings, for removal and installation information. Reinstall the wheel bearings, washer, and adjustment nut if the wheel bearings pass the inspection. 9. Using a torque wrench, tighten the wheel bearing adjustment nut to 54 N.m (40 ft. lbs.) while rotating the tire/wheel assembly. Stop the wheel from rotating and loosen the nut. Using the procedure identified in Steps 6 and 7 to measure endplay, adjust the front wheel bearing endplay until 0.025 - 0.076 mm (0.001 - 0.003 in.) endplay has been achieved. Install the nut lock and a new cotter pin. 10. Perform the Pre-Alignment inspection as identified in Group 02, Service Procedures, of the appropriate Ram Van/Wagon Service Manual. Any worn steering and/or suspension component must be replaced prior to performing an alignment. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 824 11. Perform a wheel alignment on the vehicle. Refer to the procedures identified in the appropriate Ram Van/Wagon Service Manual, Group 02, Service Procedures, Wheel Alignment. Adjust any front alignment angle not within specifications. Refer to the chart for proper alignment specifications.

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. - CASTER is the forward or rearward tilt of the steering knuckle from vertical. Tilting the top of the knuckle forward provides negative caster. Tilting the top of the knuckle rearward provides 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. CAUTION: Never attempt to modify suspension or steering components by heating or bending. NOTE: Periodic lubrication of the front suspension/steering system components may be required. Rubber bushings must never be lubricated. Always follow the recommended maintenance schedule. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Page 827 Alignment: Testing and Inspection Pre-Alignment Inspection Before starting wheel alignment, the following inspection and necessary corrections must be completed. 1. Inspect tires for size and tread wear. 2. Set tire air pressure. 3. Inspect front wheel bearings for wear. 4. Inspect front wheels for excessive radial or lateral runout and balance. 5. Inspect ball studs, linkage pivot points and steering gear for looseness, roughness or binding. 6. Inspect suspension components for wear and noise. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Page 828 Alignment: Service and Repair The front wheel alignment angles should be set to preferred specifications. This will prevent abnormal tire tread wear. 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. CAMBER AND CASTER Caster & Camber Adjustment Camber and caster angle adjustments involve repositioning the upper suspension arm pivot bar. Alignment adjustments are accomplished by changing the position of the pivot bar. Adjuster Tool 8199 is used to adjust the camber and caster angles. Tools Attached To Frame 1. Clamp the tool on the upper suspension arm frame bracket. Use the two clamp bolts to attach the tool to the bracket. 2. With the adjustment tools installed, loosen both upper suspension arm bolts completely. 3. Tighten or loosen the tool adjustment bolts to move the upper suspension arm inward or outward to obtain the proper camber and caster angles. CASTER: Move the rear position of the pivot bar in or out. This will change the caster angle significantly and camber angle only slightly. To retain camber move the forward pivot very slightly in the opposite direction. NOTE: To increase a positive caster, move the rear position of the pivot bar inward. Move the front of pivot bar outward until the original Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Page 829 camber angle is obtained. CAMBER: Move the forward position of the pivot bar in or out. This will change the camber angle significantly and caster angle only slightly. The camber angle should be adjusted to the service specifications. Refer to the Wheel Alignment Specifications chart. Tighten the pivot bar bolts to 298 Nm (220 ft. lbs.). TOE POSITION The wheel toe position is the final adjustment. 1. Secure the steering wheel with the front wheels in the straight-ahead position. For power steering vehicles, start the engine before straightening the wheels. 2. Loosen the tie rod adjustment sleeve clamp bolts. Tie Rod Adjustment 3. Adjust the wheel toe position by rotating the tie rod adjustment sleeve. 4. Position the adjustment sleeve clamps so the ends are not located at the sleeve slot. Tighten the tie rod sleeve clamps to: - LD: 23 Nm (17 ft. lbs.) - HD: 35 Nm (26 ft. lbs.) Ensure the clamp bolts are located at the underside of the sleeve. 5. Verify camber, caster and toe position. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Page 830 Adjuster, Caster & Camber 8199 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Pressure, Vacuum and Temperature Specifications Fuel Pressure: Pressure, Vacuum and Temperature Specifications Fuel Pressure Engine at curb idle ............................................................................................................................... ........................................ 339 ± 34 kPa (49.2 ± 5 psi) Pressure Leakdown (fuel pump not engaged) .................................................................................................................

BEFORE DISCONNECTING FUEL LINE AT FUEL RAIL, THIS PRESSURE MUST BE RELEASED. REFER TO THE FUEL SYSTEM PRESSURE RELEASE PROCEDURE . Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Page 838 Fuel Pressure: Testing and Inspection FUEL PRESSURE LEAK DOWN TEST Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity Test. Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1-2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by: - Fuel pressure bleeding past a fuel injector(s). - Fuel pressure bleeding past the check valve in the fuel pump module. 1. Disconnect the fuel inlet line at fuel rail. Refer to Fuel Tubes/Lines/Hoses and Clamps for procedures. On some engines, air cleaner housing removal may be necessary before fuel line disconnection. 2. Obtain correct Fuel Line Pressure Test Adapter Tool Hose. Tool number 6539 is used for 5/16" fuel lines and tool number 6631 is used for 3/8" fuel lines. Connecting Adapter Tool-Typical 3. Connect correct Fuel Line Pressure Test Adapter Tool Hose between disconnected fuel line and fuel rail. 4. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test port on the appropriate Adaptor Tool. The fittings on both tools must be in good condition and free from any small leaks before performing the proceeding test. 5. Start engine and bring to normal operating temperature. 6. Observe test gauge. Normal operating pressure should be 339 kPa + 34 kPa (49.2 psi + 5 psi). 7. Shut engine off. 8. Pressure should not fall below 30 psi for five minutes. 9. If pressure falls below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is leaking. 10. Again, start engine and bring to normal operating temperature. 11. Shut engine off. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Page 839 12. Testing for fuel injector or fuel rail leakage: Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking. 13. Testing for fuel pump cheek valve, filter/regulator check valve or fuel tube/line leakage: Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line. If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump or filter/regulator may be leaking. NOTE: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A slow loss of pressure usually indicates a defective check valve in the electric fuel pump. The electric fuel pump is not serviced separately. Replace the fuel pump module assembly. The filter/ regulator may be replaced separately on certain applications. Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for additional information. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Idle Speed > System Information > Specifications Idle Speed: Specifications Minimum Air Flow Idle ......................................................................................................................... ......................................................... 500 to 900 rpm Note: Idle speed range achieved through Minimum Air Flow Idle Test Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Idle Speed > System Information > Specifications > Page 843 Idle Speed: Testing and Inspection The following test procedure has been developed to check throttle body calibrations for correct idle conditions.

These 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 888 Ignition Cable: Testing and Inspection IGNITION CABLES Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and spark plugs. Terminals should be fully seated. The insulators should be in good condition and should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are cracked or torn must be replaced. Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the cables dry. Check for brittle or cracked insulation. Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable boot and spark plug. These shields protect the spark plug boots from damage (due to intense engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat shield. Testing When testing secondary cables for damage with an oscilloscope, follow the instructions of the equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as follows: CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during testing. This may cause possible heat damage to the catalytic converter. Total test time must not exceed ten minutes. With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to a good engine ground. If the cable and spark plug are in good condition, the engine rpm should drop and the engine will run poorly. If engine rpm does not drop, the cable and/or spark plug may not be operating properly and should be replaced. check engine cylinder compression. With the engine not running, connect one end of a test probe to a good ground. Start the engine and run the other end of the test probe along the entire length of all spark plug cables. If cables are cracked or punctured, there will be a noticeable spark jump from the damaged area to the test probe. The cable running from the ignition coil to the distributor cap can be checked in the same manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket. Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped, remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable. Test all spark plug cables in this manner. SPARK PLUG CABLE RESISTANCE Minimum Maximum 250 Ohms Per Inch 1000 Ohms Per Inch 3000 Ohms Per Foot 12,000 Ohms Per Foot To test ignition coil-to-distributor cap cable, do not remove the cable from the cap. Connect ohmmeter to rotor button (center contact) of distributor cap and terminal at ignition coil end of cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, remove the cable from the distributor cap. Connect the ohmmeter to the terminal ends of the cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, replace the cable. Inspect the ignition coil tower for cracks, burns or corrosion. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 889 Ignition Cable: Service and Repair REMOVAL AND INSTALLATION Cable Removal CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap, twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off with a steady, even force. Engine Firing Order Install cables into the proper engine cylinder firing order. When replacing the spark plug and coil cables, route the cables correctly and secure in the proper retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could also cause cross ignition of the plugs or 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 between the plug cable and the distributor cap tower. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Distributor, Ignition > Distributor Cap > Component Information > Testing and Inspection Distributor Cap: Testing and Inspection Cap Inspection-External-Typical Cap Inspection-Internal-Typical Remove the distributor cap and wipe it clean with a dry lint free cloth. Visually inspect the cap for cracks, carbon paths, broken towers or damaged rotor button. Also check for white deposits on the inside (caused by condensation entering the cap through cracks). Replace any cap that displays charred or eroded terminals. The machined surface of a terminal end (faces toward rotor) will indicate some evidence of erosion from normal operation. Examine the terminal ends for evidence of mechanical interference with the rotor tip. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Distributor, Ignition > Ignition Rotor > Component Information > Testing and Inspection Ignition Rotor: Testing and Inspection Rotor Inspection-Typical Visually inspect the rotor for cracks, evidence of corrosion or the effects of arcing on the metal tip. Also check for evidence of mechanical interference with the cap. Some charring is normal on the end of the metal tip. The silicone-dielectric-varnish-compound applied to the rotor tip for radio interference noise suppression, will appear charred. This is normal. Do not remove the charred compound. Test the spring for insufficient tension. Replace a rotor that displays any of these adverse conditions. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications Spark Plug: Specifications Torque 30 ft.lb Electrode Gap 0.040 in Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 900 Spark Plug: Application and ID Plug Type ............................................................................................................................................ ....................................................................

Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in which they were removed from the engine. A single plug displaying an abnormal condition indicates that a problem exists in the corresponding cylinder. Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or oil fouled. Refer to the Spark Plug Condition. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 902 Spark Plug: Testing and Inspection SPARK PLUG CONDITIONS Normal Operation and Cold (Carbon) Fouling Normal Operating The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is evident with most grades of commercial gasoline. There will not be evidence of electrode burning. Gap growth will not average more than approximately 0.025 mm (0.001 in) per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the electrodes filed, have the gap set and then be installed. Some fuel refiners in several areas of the United States have introduced a manganese additive (MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits. Normal Operation and Cold (Carbon) Fouling Cold Fouling/Carbon Fouling Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be caused by a clogged air cleaner element or repeated short operating times (short trips). Wet Fouling or Gas Fouling A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the fouled plugs. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 903 Oil or Ash Encrusted Oil or Ash Encrusted If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of oil entry into that particular combustion chamber. Electrode Gap Bridging Electrode Gap Bridging Electrode gap bridging may be traced to loose deposits in the combustion chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be cleaned using standard procedures. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 904 Scavenger Deposits Scavenger Deposits Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is a normal condition caused by chemical additives in certain fuels. These additives are designed to change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in condition and can be cleaned using standard procedures. Chipped Electrode Insulator Chipped Electrode Insulator A chipped electrode insulator usually results from bending the center electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation can also separate the insulator from the center electrode. Spark plugs with this condition must be replaced. Preignition Damage Pre-ignition Damage Preignition damage is usually caused by excessive combustion chamber temperature. The center electrode dissolves first and the ground electrode Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 905 dissolves somewhat latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine. Determine if ignition timing is over advanced or if other operating conditions are causing engine overheating. (The heat range rating refers to the operating temperature of a particular type spark plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon the thickness and length of the center electrodes porcelain insulator.) Spark Plug Overheating Spark Plug Overheating Overheating is indicated by a white or gray center electrode insulator that also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug overheating. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 906 Spark Plug: Service and Repair Heat Shields Spark plug cable beat shields are pressed into the cylinder head to surround each cable boot and spark plug. If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides of shield for removal. Each shield is slotted to allow for compression and removal. To install the shields, align shield to machined opening in cylinder head and tap into place with a block of wood. PLUG REMOVAL 1. Remove engine cover. Cable Removal 2. Always remove spark plug or ignition coil cables by grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady motion. Never pull directly on the cable. Internal damage to cable will result. 3. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area around the spark plug. This will help prevent foreign material from entering the combustion chamber. 4. Remove the spark plug using a quality socket with a rubber or foam insert. 5. Inspect the spark plug condition. Refer to Spark Plug Condition. PLUG CLEANING The plugs may be cleaned using commercially available spark plug cleaning equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before adjusting gap. CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will remain on the spark plug insulator and will cause plug misfire. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 907 PLUG GAP ADJUSTMENT Setting Spark Plug Gap-Typical Check the spark plug gap with a gap gauge tool. If the gap is not correct, adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center electrode. SPARK PLUG GAP 1.01 mm (0.040 in). PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged. Always tighten spark plugs to the specified torque.. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator. When replacing the spark plug and ignition coil cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground. 1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark plugs to 35-41 Nm (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications Compression Check: Specifications Compression should not be less than 689 kPa (100 psi) and not vary more than 172 kPa (25 psi) from cylinder to cylinder. If cylinder(s) have abnormally low compression pressures, repeat procedure. - If the same cylinder(s) repeat an abnormally low reading, it could indicate the existence of a problem in the cylinder. NOTE: The recommended compression pressures are to be used only as a guide to diagnosing engine problems. An engine should NOT be disassembled to determine the cause of low compression unless some malfunction is present. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications > Page 911 Compression Check: Testing and Inspection CYLINDER COMPRESSION PRESSURE TEST The results of a cylinder compression pressure test can be utilized to diagnose several engine malfunctions. Ensure the battery is completely charged and the engine starter motor is in good operating condition. Otherwise the indicated compression pressures may not be valid for diagnosis purposes. 1. Clean the spark plug recesses with compressed air. 2. Remove the spark plugs. 3. Secure the throttle in the wide-open position. 4. Disconnect the ignition coil. 5. Insert a compression pressure gauge and rotate the engine with the engine starter motor for three revolutions. 6. Record the compression pressure on the 3rd revolution. Continue the test for the remaining cylinders. Minimum cylinder compression pressure is 689 kPa (100 psi). Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Valve Clearance > System Information > Specifications Valve Clearance: Specifications These engines are equipped with hydraulic lash adjusters designed to maintain zero lash at all times. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Drive Belt > Component Information > Diagrams Belt Routing-All Engines Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Drive Belt > Component Information > Diagrams > Page 918 Drive Belt: Description and Operation ACCESSORY DRIVE BELT/TENSION The accessory drive components are operated by a single, crankshaft driven, serpentine drive belt. An automatic belt tensioner is used to maintain correct belt tension at all times. Correct accessory drive belt tension is required to be sure of optimum performance of belt driven engine accessories. If specified tension is not maintained, belt slippage may cause; engine overheating, lack of power steering assist, loss of air conditioning capacity, reduced generator output rate and greatly reduced belt life. It is not necessary to adjust belt tension on any engine. All engines are equipped with an automatic belt tensioner. The tensioner maintains correct belt tension at all times. Due to use of this belt tensioner, do not attempt to use a belt tension gauge on any engine. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Drive Belt > Component Information > Diagrams > Page 919 Drive Belt: Testing and Inspection VISUAL DIAGNOSIS Belt Ware Patterns 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 the Accessory Drive Belt Diagnosis charts 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Drive Belt > Component Information > Diagrams > Page 920 ACCESSORY DRIVE BELT DIAGNOSIS CHART Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Drive Belt > Component Information > Diagrams > Page 921 Drive Belt: Service and Repair ACCESSORY DRIVE BELT The accessory drive components are operated by a single, crankshaft driven, serpentine drive belt.

MODELS: 1999 (AB) Ram Van 1999 (AN) Dakota 1999 (BR/BE) Ram Truck 1999 (DN) Durango NOTE: THIS BULLETIN APPLIES TO VEHICLES EOUIPPED WITH A 3.9L OR 5.2L ENGINE. ENGINES BUILT BY THE MOUND ROAD ENGINE PLANT FROM FEB. 18, 1999 (JULIAN DATE OF 0499) TO MAR. 26, 1999 (JULIAN DATE OF 0859) MAY BE EFFECTED. SYMPTOM/CONDITION: A condition may exist where oil seepage past the oil filter adapter plate gasket may result in an incorrect or difficult oil leak diagnosis. The oil seepage could possibly be misdiagnosed as a rear main oil seal leak, an engine pan gasket oil leak, an intake manifold rear seal oil leak, or an oil filter gasket oil leak. DIAGNOSIS: 1. Inspect the left (driver side) engine valve cover for the Engine Bar Code Label. The label is white in color and is located on the front facing end of the valve cover. 2. Read the top line of numbers on the Engine Bar Code Label to determine if the engine in question falls on or within the Julian dates of 049 and 085 of 1999 (0499 to 0859). The top line is in the following format: TAYE2DDDCSSSSS T = Traceability coding (only T is used) A = Engine assembly code uniquely assigned by the engine plant (A through Z) Y = Model Year of engine (0 through 9) EE = Engine Plant code (E2 = Mound Road Engine Plant) DDD = Julian Date of build (0 through 365) C = Calendar year of build date (0 through 9). 55555 = Serial number (5 digits) from bar code label on back side of cyl. block An example would be TM9E2071 998187, this would decode as a 5.2L AN/DN automatic engine (M), built for the 1999 model year (9), produced at the Mound Road Engine Plant (E2), on day 071 of calendar year 1999 (0719 = 3/12/99), with a block serial number of 98187. This example falls within the criteria of the above symptom. 3. inspect the front facing end of the right engine valve cover for the presence of a small circular green label. The green label (dot) was installed on engines which have the new oil filter adapter plate gasket. There should be no need to replace these gaskets. 4. If the 3.9L or 5.2L engine build date is on or between Julian dates of 0499 and 0859, and a green circular label (dot) is not present on the front facing end of the right valve cover, then perform the Repair Procedure. 5.

ENGINES BUILT BY THE MOUND ROAD ENGINE PLANT FROM FEB. 18, 1999 (JULIAN DATE OF 0499) TO MAR. 26, 1999 (JULIAN DATE OF 0859) MAY BE EFFECTED. SYMPTOM/CONDITION: A condition may exist where oil seepage past the oil filter adapter plate gasket may result in an incorrect or difficult oil leak diagnosis. The oil seepage could possibly be misdiagnosed as a rear main oil seal leak, an engine pan gasket oil leak, an intake manifold rear seal oil leak, or an oil filter gasket oil leak. DIAGNOSIS: 1. Inspect the left (driver side) engine valve cover for the Engine Bar Code Label. The label is white in color and is located on the front facing end of the valve cover. 2. Read the top line of numbers on the Engine Bar Code Label to determine if the engine in question falls on or within the Julian dates of 049 and 085 of 1999 (0499 to 0859). The top line is in the following format: TAYE2DDDCSSSSS T = Traceability coding (only T is used) A = Engine assembly code uniquely assigned by the engine plant (A through Z) Y = Model Year of engine (0 through 9) EE = Engine Plant code (E2 = Mound Road Engine Plant) DDD = Julian Date of build (0 through 365) C = Calendar year of build date (0 through 9). 55555 = Serial number (5 digits) from bar code label on back side of cyl. block An example would be TM9E2071 998187, this would decode as a 5.2L AN/DN automatic engine (M), built for the 1999 model year (9), produced at the Mound Road Engine Plant (E2), on day 071 of calendar year 1999 (0719 = 3/12/99), with a block serial number of 98187. This example falls within the criteria of the above symptom. 3. inspect the front facing end of the right engine valve cover for the presence of a small circular green label. The green label (dot) was installed on engines which have the new oil filter adapter plate gasket. There should be no need to replace these gaskets. 4. If the 3.9L or 5.2L engine build date is on or between Julian dates of 0499 and 0859, and a green circular label (dot) is not present on the front facing end of the right valve cover, then perform the Repair Procedure. 5. If still leaking, refer to the appropriate Service Manual for additional diagnosis.

It is located in the liquid line between the condenser outlet and the evaporator inlet. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Filters > Refrigerant Filter > Component Information > Specifications > Page 973 Refrigerant Filter: Description and Operation Filter-Drier A single filter-drier unit is used for both the front-only A/C system, and for the combined front and rear A/C system. The filter-drier is mounted on the right side of the engine compartment in front of the heater-A/C housing. It is located in the liquid line between the condenser outlet and the evaporator inlet. Refrigerant enters the filter-drier as a high-pressure, high-temperature liquid. The filter-drier performs a filtering action to prevent foreign material in the refrigerant from contaminating the expansion valve. A desiccant bag is mounted inside the filter-drier canister to absorb any moisture which may have entered and become trapped within the refrigerant system. In addition, during periods of high demand air conditioner operation, the filter-drier acts as a reservoir to store surplus liquid refrigerant. The filter-drier cannot be repaired. If the filter-drier is faulty or damaged, if the refrigerant system has been contaminated, or if the system has been left open to the atmosphere for an indeterminable period, it must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Filters > Refrigerant Filter > Component Information > Specifications > Page 974 Refrigerant Filter: Service and Repair FILTER - DRIER WARNING: REVIEW THE WARNINGS AND CAUTIONS BEFORE PERFORMING THE FOLLOWING OPERATION.

Radiator lower hoses are spring-reinforced to prevent collapse from water pump suction at moderate and high engine speeds. Inspect the hoses at regular intervals. Replace hoses that are cracked, feel brittle when squeezed or swell excessively when the system is pressurized. The use of molded replacement hoses is recommended. When performing a hose inspection, inspect the radiator lower hose for proper position and condition of the spring. Hose Clamp Tool-Typical WARNING: CONSTANT TENSION HOSE CLAMPS ARE USED ON MOST COOLING SYSTEM HOSES. WHEN REMOVING OR INSTALLING, USE ONLY TOOLS DESIGNED FOR SERVICING THIS TYPE OF CLAMP, SUCH AS SPECIAL CLAMP TOOL (NUMBER 6094). SNAP-ON CLAMP TOOL (NUMBER HPC-20) MAY BE USED FOR LARGER CLAMPS. ALWAYS WEAR SAFETY GLASSES WHEN SERVICING CONSTANT TENSION CLAMPS. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Hoses > Coolant Line/Hose > Component Information > Description and Operation > Page 979 Clamp Number/Letter Location CAUTION: A number or letter is stamped into the tongue of constant tension clamps. If replacement is necessary, use only an original equipment clamp with matching number or letter. For all vehicles: In areas where specific routing and clamps are not provided, be sure that hoses are positioned with sufficient clearance. Check clearance from exhaust manifolds and pipe, fan blades, drive belts and sway bars. Improperly positioned hoses can be damaged, resulting in coolant loss and engine overheating. Ordinary worm gear type hose clamps (when equipped) can be removed with a straight screwdriver or a hex socket. To prevent damage to hoses or clamps, the hose clamps should be tightened to 4 Nm (34 inch lbs.) torque. Do not over tighten hose clamps. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Hoses > Hose/Line HVAC > Component Information > Specifications > A/C Discharge Hose/Line Hose/Line HVAC: Specifications A/C Discharge Hose/Line Tighten the Compressor mounting screw to 22 Nm (200 in. lbs.).

High pressures are produced in the system when it is operating. Extreme care must be exercised to make sure that all refrigerant system connections are pressure tight. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the hose. Sharp bends will reduce the flow of refrigerant. The flexible hose lines should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold. It is a good practice to inspect all flexible refrigerant system hose lines at least once a year to make sure they are in good condition and properly routed. There are two types of refrigerant fittings: - All fittings with O-rings need to be coated with refrigerant oil before installation. Use only O-rings that are the correct size and approved for use with R-134a refrigerant. Failure to do so may result in a leak. - Unified plumbing connections with gaskets cannot be serviced with O-rings. The gaskets are not reusable and new gaskets do not require lubrication before installing. Using the proper tools when making a refrigerant plumbing connection is very important. Improper tools or improper use of the tools can damage the refrigerant fittings. Always use two wrenches when loosening or tightening tube fittings. Use one wrench to hold one side of the connection stationary while loosening or tightening the other side of the connection with a second wrench. The refrigerant must be recovered completely from the system before opening any fitting or connection. Open the fittings with caution, even after the refrigerant has been recovered. If any pressure is noticed as a fitting is loosened, tighten the fitting and recover the refrigerant from the system again. Do not discharge refrigerant into the atmosphere. Use an R-134a refrigerant recovery/recycling device that meets SAE Standard J2210. The refrigerant system will remain chemically stable as long as pure, moisture-free R-134a refrigerant and refrigerant oil is used. Dirt, moisture, or air can upset this chemical stability Operational troubles or serious damage can occur if foreign material is present in the refrigerant system. When it is necessary to open the refrigerant system, have everything needed to service the system ready. The refrigerant system should not be left open to the atmosphere any longer than necessary Cap or plug all lines and fittings as soon as they are opened to prevent the entrance of dirt and moisture. All lines and components in parts stock should be capped or sealed until they are to be installed. All tools, including the refrigerant recycling equipment, the manifold gauge set, and test hoses should be kept clean and dry. All tools and equipment must be designed for R-134a refrigerant. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Hoses > Hose/Line HVAC > Component Information > Specifications > Page 987 Hose/Line HVAC: Description and Operation Refrigerant Hoses/Lines/Tubes Precautions Kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire system.

All tools, including the refrigerant recycling equipment, the manifold gauge set, and test hoses should be kept clean and dry. All tools and equipment must be designed for R-134a refrigerant. SYSTEM OPERATION Refrigerant Line The refrigerant lines and hoses are used to carry the refrigerant between the various air conditioning system components. A barrier hose design with a nylon tube inner hose liner is used for the R-134a air conditioning system on this vehicle. This nylon liner helps to further contain the R-134a refrigerant, which has a smaller molecular structure than R-12 refrigerant. The ends of the refrigerant hoses are made from lightweight aluminum or steel, and use braze-less fittings. Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system. Kinks and sharp bends reduce the flow of refrigerant in the system. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the hose. In addition, the flexible hose refrigerant lines should be routed so they are at least 80 mm (3 inches) from the exhaust manifold. High pressures are produced in the refrigerant system when the air conditioning 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 with other components of the HVAC system with peanut-block style fittings. A status seal type flat steel gasket with a captured compressible O-ring, is used to mate plumbing lines with A/C 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. Low Pressure Gauge Hose The low pressure hose (Blue with Black stripe) attaches to the suction service port. This port is located on the suction line jumper, near the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Hoses > Hose/Line HVAC > Component Information > Specifications > Page 988 filter-drier at the front of the engine compartment. High Pressure Gauge Hose The high pressure hose (Red with Black stripe) attaches to the discharge service port. This port is located on the discharge line between the compressor and the condenser, near the front of the engine compartment. Recovery/Recycling/Evacuation/Charging Hose The center manifold hose (Yellow, or White, with Black stripe) is used to recover, evacuate, and charge the refrigerant system. When the low or high pressure valves on the manifold gauge set are opened, the refrigerant in the system will escape through this hose. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Hoses > Hose/Line HVAC > Component Information > Service and Repair > A/C Discharge Hose/Line Replacement Hose/Line HVAC: Service and Repair A/C Discharge Hose/Line Replacement A/C SUCTION AND DISHARGE LINE Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system.

DOT 3 Standard .............................................................................................................................................. ........................................................... SAE J1703 NOTE: The brake fluid used in this vehicle must conform to DOT 3 specifications and SAE J1703 standards. No other type of brake fluid is recommended or approved for usage in the vehicle brake system. Use only Mopar brake fluid or an equivalent from a tightly sealed container. CAUTION: Never use reclaimed brake fluid or fluid from a container which has been left open. An open container of brake fluid will absorb moisture from the air and contaminate the fluid. CAUTION: Never use any type of a petroleum based fluid in the brake hydraulic system. Use of such type fluids will result in seal damage of the vehicle brake hydraulic system causing a failure of the vehicle brake system. Petroleum based fluids would be items such as engine oil, transmission fluid, power steering fluid, etc. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Brake Fluid > Component Information > Specifications > Page 1007 Brake Fluid: Service Precautions SAFETY PRECAUTIONS WARNING: Brake fluid may be irritating to the skin or eyes. In case of contact, take the following actions: * Eye Contact-rinse eyes thoroughly with water. * Skin Contact-wash skin with soap and water. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Brake Fluid > Component Information > Specifications > Page 1008 Brake Fluid: Testing and Inspection CAUTION: The hydraulic fluid used in automotive brake systems is hygroscopic. This means that the hydraulic fluid tends to absorb moisture from the atmosphere over periods of time. As hydraulic brake fluid absorbs moisture, it effects the function of the vehicles hydraulic brake system. For this reason, the vehicle's hydraulic brake fluid should be drained and replaced using fresh clean hydraulic brake fluid every two years. When replacing hydraulic brake fluid, use only Mopar brake fluid or an equivalent from a sealed container. Brake fluid must conform to DOT 3 specifications. BRAKE FLUID CONTAMINATION Indications of fluid contamination are swollen or deteriorated rubber parts. Swelling indicates 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 the fluid separates into layers, there is mineral oil or other fluid contamination of the brake fluid. If the brake fluid is contaminated, drain and thoroughly flush the brake system. Replace all the rubber parts or components containing rubber coming into contact with the brake fluid. This includes the master cylinder, proportioning valves, caliper seals, wheel cylinder seals, ABS hydraulic control unit (HCU), and all hydraulic fluid hoses. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Brake Fluid > Component Information > Specifications > Page 1009 Brake Fluid: Service and Repair BRAKE FLUID LEVEL Always clean the master cylinder filler caps before checking fluid level. If not cleaned, dirt from the caps could enter the fluid. Correct fluid level is to the bottom of the ring indicators on the reservoir. If necessary, add fluid to correct the level. With disc brake equipped vehicles, fluid level in the front brake reservoir will decrease slightly in proportion to normal lining wear. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Coolant > Component Information > Specifications > Capacity Specifications Coolant: Capacity Specifications Coolant Capacity ................................................................................................................................. ...................................................... 12.3 L (13.1 Qts.)

The recommended mixture of 50/50 ethylene-glycol and water will provide protection against freezing to -37° C (-35° F). The antifreeze concentration must always be a minimum of 44%, year round, in all climates. If percentage is lower than 44%, 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. 100 Percent Ethylene-Glycol Should Not Be Used Use of 100 Percent Ethylene-Glycol will cause formation of additive deposits in the system, as the corrosive inhibitive additives in ethylene-glycol require the presence of water to dissolve. The deposits act as insulation, causing temperatures to rise 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 % ethylene-glycol freezes at 22° C (-8° F). Propylene-Glycol Formulations Should Not Be Used Propylene-glycol formulations do not meet the required specifications. 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 degrees 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 and freeze up. Propylene-Glycol also has a poorer heat transfer characteristics than ethylene-glycol. This can increase cylinder head temperatures under certain conditions. Propylene-Glycol/Ethylene-Glycol Mixtures Should Not Be Used Propylene-glycol/ethylene-glycol mixtures can cause the destabilization of various corrosion inhibitors, causing damage to the coling system components. Also, once ethylene-glycol and propylene-glycol based coolants are mixed in the vehicle, conventional methods of determining the freeze point will not be accurate. Both the refractive index and specific gravity differ between the ethylene-glycol and propylene-glycol. CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can cause problems associated with 100 percent ethylene-glycol. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Coolant > Component Information > Specifications > Page 1015 Coolant: Service Precautions DO NOT mix green colored coolant with orange colored coolant. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Coolant > Component Information > Description and Operation > Coolant Performance Coolant: Description and Operation Coolant Performance ETHYLENE-GLYCOL MIXTURES The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle open ating conditions.

DISCUSSION: The axle lubricant used in all corporate axles was changed in formulation starting at the beginning of the 1998 model year. The corporate axles involved include: the 8.25 and 9.25 rear axles, and the C205F front axle. The new lubricant in use is SAE 75W-90 p/n 05010320AA. The lubricant change was made as a fuel economy improvement. The new axle lubricant is more chemically aggressive/reactive when in contact with the previous used Room Temperature Vulcanizable (RTV) sealant. Because of this condition, the RTV used in assembly of the pan/cover to the axle housing was revised and improved. When re-sealing axle covers, using the proper sealing material to minimize any potential sealant breakdown is important. The only recommended sealing material for all corporate axle covers is MOPAR RTV Sealant, p/n 05013477M. This RTV is red/orange in color. NOTE: IF SAE 75W-90 LUBRICANT IS USED TO REFILL ANY CORPORATE AXLE, THEN THE RED/ORANGE MOPAR RTV SEALANT, P/N 05013477AA, SHOULD BE USED TO SEAL THE COVER TO THE AXLE HOUSING. To optimize sealant performance and enhance adhesion, flanges should be clean and free of residual lubricant. The mating flanges should first be cleaned of any excess old RTV using a plastic putty knife. Final cleaning/degreasing shall be done by spraying MOPAR Brake Parts Cleaner, p/n 04549623, on the carrier and cover flanges, followed by a wipe with a clean dry cloth. Care should be taken to avoid spraying the parts cleaner inside the carrier. Once the RTV has been applied, the axle cover is to be installed to the housing within 3 to 5 minutes to prevent skinning over of the RTV.

DISCUSSION: The customer or servicing technician may notice a milky-like appearance to the 9.25 inch rear axle fluid. This condition may be brought to the customer's attention when the axle fluid is inspected during normal service. Other than the concern for the color of axle fluid, the customer does not experience any other axle complaint. The customer or servicing technician may be concerned because a milky-like appearance to the axle fluid may also indicate the presence of water. The cause of the milky-like appearance to the axle fluid may be due to the use of a white color gear marking compound during the axle assembly process. Axle gear marking compound is used to verify correct ring and pinion gear alignment during manufacture. The 9.25 inch rear axle is assembled on two different assembly lines. To visually distinguish axles from each assembly line, one assembly line used a white color gear marking compound (versus yellow). Half of the axles that were assembled during the above time frame may have the white gear marking compound mixed with the rear axle fluid. The white color gear marking compound is no longer in use by the axle assembly plant. NOTE: IF THE MILKY-LIKE REAR AXLE FLUID APPEARANCE IS DUE TO THE WHITE GEAR MARKING COMPOUND, THEN NO SERVICE ACTION IS NECESSARY TO ADDRESS THIS CONDITION. If the milky-like rear axle fluid appearance is due to the presence of water, then the rear axle will require service. Axle fluid, contaminated with water, may cause rust and damage to the internal components of the axle. Any water in the axle fluid will begin to boil off (reach its gaseous state) before the oil. Placing a small sample of axle fluid on a hot steel surface (around 100C or 212F) will cause any water that may be present in the fluid to boil off with a "sizzle-like" sound.

WJ/WG and ZH vehicles use unique power steering fluids. Refer to the table to identify factory fill and the approved service power steering fluid by year and model. Note that MS9602 is Red in color and MS5931 and MS9933 are Amber/Yellow in color. All three fluids will darken in color with usage and fluid color is no longer an indication of fluid condition. The part numbers for MS9602 are 05013457AA (quart) and 05013458AA (gallon). The part number for MS5931 is 04883077 (quart). The part number for MB345 is 05127381AA. MS9602 should not be mixed or used as a "topping off" fluid on systems requiring MS5931. On some past models, MS9602 should be used as the replacement fluid. On these models, if a power steering system is being serviced that results in a large fluid loss, such as a pump, hose or gear/rack replacement, the complete system should be drained and filled with MS9602. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Power Steering Fluid > Component Information > Technical Service Bulletins > Steering - Power Steering Fluid Usage > Page 1058 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Power Steering Fluid > Component Information > Technical Service Bulletins > Steering - Power Steering Fluid Usage > Page 1059 NOTE: This bulletin supersedes owner's and service manuals for the vehicles listed above that may state to use MS9933 in the power steering system, and that may state not to use automatic transmission fluid in the power steering system.

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 air conditioning system. Even a small amount of R-12 added to an R-134a refrigerant system will cause compressor failure, refrigerant oil sludge or poor air conditioning 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 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 compressor identifying to service technicians that the air conditioning system is equipped with R-134a. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Refrigerant Oil > Component Information > Specifications > Capacity Specifications Refrigerant Oil: Capacity Specifications Total System (Front Only) ................................................................................................................... ............................................................ 236 ml 8.0 oz.

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. The TR-105 compressor used in this vehicle is designed to use an SP-15 PAG refrigerant oil. Use only refrigerant oil of this same type to service the refrigerant system. 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 compressor damage, and too much can reduce air conditioning system performance. PAG refrigerant oil is much 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Refrigerant Oil > Component Information > Specifications > Page 1076 Refrigerant Oil: Service and Repair Refrigerant Oil Level When an air conditioning system is assembled at the factory, all components except the compressor and the combination coil, if the vehicle is so equipped, are refrigerant oil free. After the refrigerant system has been charged and operated, the refrigerant oil in the compressor and the combination coil is dispersed throughout the refrigerant system. The combination coil, evaporator, filter-drier, condenser, and compressor will each retain a significant amount of the needed refrigerant oil. It is important to have the correct amount of oil in the refrigerant system. This ensures proper lubrication of the compressor. Too little oil will result in damage to the compressor. Too much oil will reduce the cooling capacity of the air conditioning system. It will not be necessary to check the oil level in the 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 ml (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 Chart Refrigerant oil must be added when a filter-drier, evaporator coil, combination coil, or condenser are replaced. See the Refrigerant Oil Capacities chart. When a compressor is replaced, the refrigerant oil must be drained from the old compressor and measured. Drain all of the refrigerant oil from the new compressor, then fill the new compressor with the same amount of refrigerant oil that was drained out of the old compressor. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures Brake Bleeding: Service and Repair Antilock Brake System Bleeding Procedures W/ Four Wheel Antilock Brakes 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. W/ Rear Wheel Antilock Brakes Use Mopar 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. Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into small bubbles that are distributed throughout the hydraulic system. This will make additional bleeding operations necessary. Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow additional air to be drawn into the system. Check the cylinder fluid level frequently and add fluid as needed. Bleed only one brake component at a time in the following sequence: Master Cylinder - Combination Valve - Rear Antilock Valve - Left Rear Wheel - Right Rear Wheel - Right Front Wheel - Left Front Wheel MANUAL BLEEDING 1. Remove reservoir filler caps and fill reservoir. 2. If calipers, or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws. Then close each bleed screw as fluid starts to drip from it. Top off master cylinder reservoir once more before proceeding. Bleed Hose Setup 3. Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially filled with brake fluid. Be sure end of bleed hose is immersed in fluid. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures > Page 1081 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. PRESSURE BLEEDING If pressure bleeding equipment will be used, the front brake metering valve will have to be held open to bleed the front brakes. The valve stem is located in the forward end or top of the combination valve. The stem must either be pressed inward, or held outward slightly. A spring clip tool or helper is needed to hold the valve stem in position. Follow the tank manufacturer's instructions carefully when using pressure equipment. Do not exceed the tank manufacturer's pressure recommendations. Generally, a tank pressure of 16-20 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. Use the adapter provided with the equipment or Adapter 6921. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures > Page 1082 Brake Bleeding: Service and Repair Base Brake System Bleeding Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only.

Before attempting to diagnose or service any airbag system or related steering wheel, steering column, or instrument panel components you must first disconnect and isolate the battery negative (ground) cable. Then wait two minutes for the system capacitor to discharge before further system service. This is the only sure way to disable the airbag system. failure to do this could result in accidental airbag deployment and possible personal injury. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Air Bag Disarming > Page 1087 Air Bag(s) Arming and Disarming: Service and Repair Air Bag Arming Air Bag Arming 16-Way Data Link Connector - Typical A DRB scan tool is required for diagnosis of the airbag system. See the proper Diagnostic Procedures for more information. 1. Connect the DRB scan tool to the 16-way data link wire harness connector. The connector is located on the driver side lower edge of the instrument panel, below the steering column. 2. Exit the vehicle with the DRB. Be certain that the DRB contains the latest version of the proper DRB software. 3. Connect the negative battery terminal. 4. From outside of the vehicle (away from the airbags in case of an accidental deployment) turn the ignition switch to the ON position 5. Using the DRB, read and record the active Diagnostic Trouble Code (DTC) data. 6. Read and record any stored DTC data. 7. See the proper Diagnostic Procedures if any DTC's are found. 8. After completing the necessary repairs, try to erase the stored DTC data. If any problems remain, the stored DTC data will not erase. See the proper Diagnostic Procedures for the procedures to diagnose any stored DTC that will not erase. 9. With the ignition switch still in the On position, check to be certain that nobody is in the vehicle. 10. From outside of the vehicle (away from the airbags in case of an accidental deployment) turn the ignition switch to the OFF position for about ten seconds, and then back to the ON position. Observe the airbag indicator lamp in the instrument cluster. It should light for six to eight seconds, and then go out. This indicates that the airbag system is functioning normally. NOTE: If the airbag indicator lamp fails to light, or lights and stays on, there is an airbag system malfunction. See the proper Diagnostic Procedures to diagnose the problem. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Circuit Breaker > Component Information > Description and Operation Circuit Breaker: Description and Operation CIRCUIT BREAKER SYSTEM OPERATION An automatic resetting circuit breaker in the junction block is used to protect the power seat system circuit.

MODELS: 1999 (AB) Ram Van 1999 (AN) Dakota 1999 (BR/BE) Ram Truck 1999 (DN) Durango 1999 (TJ) Wrangler 1999 (WJ) Grand Cherokee 1999 (XJ) Cherokee DISCUSSION: Recent quality analysis has revealed an issue with repeated repairs for the same Diagnostic Trouble Code (DTC). The DTC may be due to an overlooked open circuit used to power the component in question. In most instances, either the circuit fuse has been erroneously removed or the fuse itself has an open (blown). The component in question, and its circuit, are often protected by two fuses. It is usually the lower amperage fuse that is either missing or open. The lower amperage fuse is positioned electrically in the circuit between the component in question and either a relay (Auto Shut Down, 02 heater) or the ignition switch. The lower amperage fuse will be located either in the underhood Power Distribution Center (PDC) or in the instrument panel Junction Block. The lower amperage fuse is often missing because it was removed erroneously for use in another low current circuit. If the lower amperage fuse is open (blown), then the circuit and component in question must be checked for an electrical short. Check to make sure that the open fuse was not exchanged with another fuse or was damaged by an installed accessory. NOTE: IF AN OXYGEN SENSOR IS REPLACED, VERIFY THAT THE CIRCUIT FUSE IS GOOD. AN OXYGEN SENSOR HEATER, WHEN DAMAGED OR OVERHEATED, MAY SHORT THE CIRCUIT AND CAUSE THE FUSE TO OPEN (BLOW). The higher amperage fuse should be checked, but is not normally the cause of the DTC. The higher amperage fuse is located in the underhood PDC. It is positioned electrically in the circuit between the battery and either the relay (Auto Shut Down, 02 heater) or the ignition switch. Refer to the applicable Diagnostic Procedures Manual and/or Service Manual (Group 8) for further technical assistance. The following is a list of the components frequently replaced erroneously due to an open fuse. Included are the possible DTC(s) which would be generated as a result. 1).

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1113 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1114 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1115 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1116 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1117 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1118 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1128 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1129 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information >

The original tire should be repaired or replaced at the first opportunity and reinstall. Do not exceed speeds of 50 MPH. Refer to Owner's Manual for complete details. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Description and Operation Wheels: Description and Operation 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. Fig. 1 All models use stamped steel, cast aluminum or forged aluminum wheels. Every wheel has raised sections between the rim flanges and rim drop well 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Description and Operation > Page 1165 Wheels: Testing and Inspection Inspect wheels for: Excessive run out - Dents or cracks - Damaged wheel lug nut holes - Air Leaks from any area or surface of the rim 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 should 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. USED WHEELS ARE NOT RECOMMENDED. THE SERVICE HISTORY OF THE WHEEL MAY HAVE INCLUDED SEVERE TREATMENT OR VERY HIGH MILEAGE. THE RIM COULD FAIL WITHOUT WARNING. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Description and Operation > Page 1166 Wheels: Service and Repair INSTALLATION The wheel studs and nuts are designed for specific applications. They must be replaced with equivalent parts. Do not use replacement parts of lesser quality or a substitute design. All aluminum and some steel wheels have wheel stud nuts which feature an enlarged nose. This enlarged nose is necessary to ensure proper retention of the aluminum wheels. NOTE: Do not use chrome plated lug nuts with chrome plated wheels. Before installing the wheel, be sure to remove any build up of corrosion on the wheel mounting surfaces. Ensure wheels are installed with good metal-to-metal contact. Improper installation could cause loosening of wheel nuts. This could affect the safety and handling of your vehicle. Lug Nut Tightening Pattern To install the wheel, first position it properly on the mounting surface. All wheel nuts should then be tightened just snug. Gradually tighten them in sequence to the proper torque specification. Never use oil or grease on studs or nuts. Wheels must be replaced if they have: Excessive runout - Bent or dented - Leak air through welds - Have damaged bolt holes - Wheel repairs employing hammering, heating, or welding are not allowed. Original equipment wheels are available through your dealer. Replacement wheels from any other source should be equivalent in: Load carrying capacity - Diameter - Width - Offset - Mounting configuration Failure to use equivalent replacement wheels may affect the safety and handling of your vehicle. Replacement with used wheels is not recommended. Their service history may have included severe treatment. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Wheels and Tires > Wheel Bearing > Component Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised Wheel Bearing: Technical Service Bulletins Steering Wander - Diagnosis and Correction Revised NUMBER: 19-07-00 GROUP: Steering DATE: September 22, 2000 SUBJECT: Steering Wander Diagnosis OVERVIEW: This bulletin provides a diagnostic procedure for steering wander. MODELS: 1998-2001 (AB) Ram Van/Wagon SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight steering corrections are necessary to be able to keep the vehicle moving in a straight line. Steering wander can be created by a number of different conditions including but not limited to the following: ^ Non-factory installed options. ^ Tires or wheels of different size. ^ Aftermarket wheels. ^ Tires that have a belt that has shifted. ^ Incorrect tire pressure. ^ A vehicle that is carrying extra added weight (e.g. tool boxes). ^ Steering and/or suspension components that are worn or damaged. ^ Wheel bearings that are loose, worn, or damaged. ^ A vehicle that is not within alignment specifications. NOTE: UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER. The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering system components are functioning as designed and are not the root cause of steering wander. DIAGNOSIS: 1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to exceed the front or rear Gross Axle Weight Rating (GAWR). 2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to wander and should be replaced before continuing with the diagnosis. 3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove box). NOTE: TIRE PRESSURES ARE NORMALLY SET TO THE LIGHT LOAD SPECIFICATION WHEN PERFORMING STEERING WANDER DIAGNOSIS BUT, ONLY IF THE VEHICLE IS AT CURB OR LIGHT LOAD CONDITIONS. 4. Validate the customer's concern by test driving the vehicle on a smooth highway, free of road crown, ruts, speed bumps, or potholes. Drive the vehicle at speeds between 80 - 113 km/h (50 - 70 mph), preferably without cross wind conditions. If crosswind conditions are prevalent, drive the vehicle in both directions relative to the crosswind. Proceed to the next step if the vehicle exhibits a steering wander condition. NOTE: VEHICLES THAT DO NOT EXHIBIT A STEERING WANDER CONDITION DURING THE ROAD TEST MAY HAVE HAD THE CONDITION CORRECTED WITH STEPS 1-3 OR THE CONDITION MAY HAVE BEEN CAUSED BY ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, ETC.). 5. Raise the vehicle on an appropriate lift. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Wheels and Tires > Wheel Bearing > Component Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 1171 6.

Place your hands at the top and bottom of the tire/wheel assembly and push the tire/wheel assembly inboard (Figure 2). Zero the dial indicator. With your hands at the top and bottom of the tire/wheel assembly, pull the tire/wheel assembly outboard (Figure 3). Record the dial indicator reading. Perform this procedure on both front wheel bearings and proceed to the next step if the wheel bearing endplay exceeds 0.025 - 0.076 mm (0.001 - 0.003 in.). Proceed to Step 9 if wheel-bearing endplay on both front wheel bearings are within specifications. NOTE: WHEEL BEARING INSPECTION AND ADJUSTMENT IS ONLY REQUIRED ON WHEEL BEARINGS EXCEEDING 0.025 - 0.076 MM (0.001 - 0.003 IN.) ENDPLAY. 8. Remove the wheel bearing protective end cap, cotter pin, nut lock, nut, and washer from the spindle. Inspect the wheel bearings. If it is determined that wheel bearing replacement is necessary, refer to the appropriate Ram Van/Wagon Service Manual, Group 02, Wheel Bearings, for removal and installation information. Reinstall the wheel bearings, washer, and adjustment nut if the wheel bearings pass the inspection. 9. Using a torque wrench, tighten the wheel bearing adjustment nut to 54 N.m (40 ft. lbs.) while rotating the tire/wheel assembly. Stop the wheel from rotating and loosen the nut. Using the procedure identified in Steps 6 and 7 to measure endplay, adjust the front wheel bearing endplay until 0.025 - 0.076 mm (0.001 - 0.003 in.) endplay has been achieved. Install the nut lock and a new cotter pin. 10. Perform the Pre-Alignment inspection as identified in Group 02, Service Procedures, of the appropriate Ram Van/Wagon Service Manual. Any worn steering and/or suspension component must be replaced prior to performing an alignment. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Maintenance > Wheels and Tires > Wheel Bearing > Component Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 1172 11.

Rotate crankshaft until No.1 cylinder is at top dead center on the firing stroke. 2. When in this position, the timing mark of vibration damper should be under "0" on the timing indicator. 3. Install the shaft so that after the gear spirals into place, it will index with the oil pump shaft. The slot on top of oil pump shaft should be aligned towards the left front intake manifold attaching bolt hole. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Lifter / Lash Adjuster, Valve > Component Information > Specifications Lifter / Lash Adjuster: Specifications Body Diameter 0.9035 - 0.9040 in Clearance in Block 0.0011 - 0.0024 in Dry Lash 0.06 - 0.210 in Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Lifter / Lash Adjuster, Valve > Component Information > Specifications > Page 1209 Lifter / Lash Adjuster: Testing and Inspection 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 (30-80 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, operate engine at idle 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 leak-down 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Lifter / Lash Adjuster, Valve > Component Information > Service and Repair > Removal and Installation Lifter / Lash Adjuster: Service and Repair Removal and Installation REMOVAL 1.

The following is the recommended procedures for the use of Plastigage: 1. Remove oil film from surface to be checked. Plastigage is soluble in oil. 2. Place a piece of Plastigage across the entire width of the bearing cap shell. Position the Plastigage approximately 6.35 mm (1/4 inch) off center and away from the oil holes. In addition, suspect areas can be checked by placing the Plastigage in the suspect area. 3. The crankshaft must be turned until the connecting rod to be checked starts moving toward the top of the engine. Only then should the rod cap with Plastigage in place be assembled. Tighten the 3.9L, and 5.2L rod cap nut to 61 Nm (45 ft. lbs.) torque. DO NOT rotate the crankshaft or the Plastigage may be smeared, giving inaccurate results. 4. Remove the bearing cap and compare the width of the flattened Plastigage with the scale provided on the package. Plastigage generally comes in 2 scales (one scale is in inches and the other is a metric scale). Locate the band closest to the same width. This band shows the amount of clearance. Differences in readings between the ends indicate the amount of taper present. Record all readings taken (refer to Engine Specifications). 5. Plastigage is available in a variety of clearance ranges.

The pistons are elliptically turned so that the diameter at the pin boss is less than its diameter across the thrust face. This allows for expansion under normal operating conditions. Under operating temperatures, expansion forces the pin bosses away from each other, causing the piston to assume a more nearly round shape. The piston pin rotates in the piston only and is retained by the press interference fit of the Piston pin in the connecting rod. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Block Assembly > Piston, Engine > Component Information > Service and Repair > Removal and Installation Piston: Service and Repair Removal and Installation REMOVAL 1.

Measure the concentricity of valve seat using a dial indicator. Total runout should not exceed 0.051 mm (0.002 inch) total indicator reading. 3. Inspect the valve seat with Prussian blue to determine where the valve contacts the seat. To do this, coat valve seat LIGHTLY with Prussian blue then set valve in place. Rotate the valve with light pressure. If the blue is transferred to the center of valve face, contact is satisfactory. If the blue is transferred to the top edge of valve face, lower valve seat with a 15° stone. If the blue is transferred to bottom edge of valve face raise valve seat with a 60° stone. 4. When seat is properly positioned the width of intake seats should be 1.016-1.524 mm (0.040-0.060 inch). The width of the exhaust seats should be 1.524-2.032 mm (0.060-0.080 inch). VALVE SPRING INSPECTION Testing Valve Spring For Compressed Length Whenever valves have been removed for inspection, reconditioning or replacement, valve springs should be tested. As an example the compression length of the spring to be tested is 1-5/16 inch. Turn table of Universal Valve Spring Tester Tool until surface is in line with the 1-5/16 inch mark on the threaded stud. Be sure the zero mark is to the front. Place spring over stud on the table and lift compressing lever to set tone device. Pull on torque wrench until ping is heard. Take reading on torque wrench at this instant. Multiply this reading by 2. This will give the spring load at test length. Fractional measurements are indicated on the table for finer adjustments. Refer to specifications to obtain specified height and allowable tensions.

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 the Accessory Drive Belt Diagnosis charts 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt > Component Information > Diagrams > Page 1325 ACCESSORY DRIVE BELT DIAGNOSIS CHART Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt > Component Information > Diagrams > Page 1326 Drive Belt: Service and Repair ACCESSORY DRIVE BELT The accessory drive components are operated by a single, crankshaft driven, serpentine drive belt. An automatic belt tensioner is used to maintain correct belt tension at all times. CAUTION: Do not attempt to check belt tension with a belt tension gauge on vehicles equipped with an automatic belt tensioner. REMOVAL Belt Tensioner-Typical 1. Attach a socket/wrench to pulley mounting bolt of automatic tensioner. 2. Rotate tensioner assembly clockwise (as viewed from front) until tension has been relieved from belt. 3. Remove belt from idler pulley first. 4. Remove belt from vehicle. INSTALLATION Belt Routing-All Engines CAUTION: When installing "serpentine" accessory drive belt, belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction. The correct belt with correct length must be used. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt > Component Information > Diagrams > Page 1327 The following belt routing schematics are published from the latest information available at the time of publication. If anything differs between these schematics and the Belt Routing Label, use the schematics on Belt Routing Label. This label is located in the engine compartment. 1. Position drive belt over all pulleys except idler pulley. This pulley is located between generator and A/C compressor. 2. Attach a socket/wrench to pulley mounting bolt of automatic tensioner. 3. Rotate socket/wrench clockwise. Place belt over idler pulley. Let tensioner rotate back into place. Remove wrench. Be sure belt is properly seated on all pulleys. Tensioner Indexing Marks 4. Check belt indexing marks. 5. The tensioner is equipped with an indexing arrow on back of tensioner and an indexing mark on tensioner housing. If a new belt is being installed, arrow must be within approximately 3 mm (1/8 in.) of indexing mark (Point B). Belt is considered new if it has been used 15 minutes or less. If this specification cannot be met, check for: ^ The wrong belt being installed (incorrect length/ width) ^ Worn bearings on an engine accessory (A/C compressor, power steering pump, water pump, idler pulley or generator) ^ A pulley on an engine accessory being loose ^ Misalignment of an engine accessory ^ Belt incorrectly routed. A used belt should be replaced if tensioner indexing arrow has moved beyond point A. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt Tensioner > Component Information > Specifications Drive Belt Tensioner: Specifications Belt Tensioner Pulley 45 ft.lb Belt Tensioner to Bracket 50 ft.lb Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt Tensioner > Component Information > Specifications > Page 1331 Drive Belt Tensioner: Description and Operation AUTOMATIC BELT TENSIONER Belt Tensioner-Typical Drive belts on all engines are equipped with a spring loaded automatic belt tensioner.

MODELS: 1999 (AB) Ram Van 1999 (AN) Dakota 1999 (BR/BE) Ram Truck 1999 (DN) Durango NOTE: THIS BULLETIN APPLIES TO VEHICLES EOUIPPED WITH A 3.9L OR 5.2L ENGINE. ENGINES BUILT BY THE MOUND ROAD ENGINE PLANT FROM FEB. 18, 1999 (JULIAN DATE OF 0499) TO MAR. 26, 1999 (JULIAN DATE OF 0859) MAY BE EFFECTED. SYMPTOM/CONDITION: A condition may exist where oil seepage past the oil filter adapter plate gasket may result in an incorrect or difficult oil leak diagnosis. The oil seepage could possibly be misdiagnosed as a rear main oil seal leak, an engine pan gasket oil leak, an intake manifold rear seal oil leak, or an oil filter gasket oil leak. DIAGNOSIS: 1. Inspect the left (driver side) engine valve cover for the Engine Bar Code Label. The label is white in color and is located on the front facing end of the valve cover. 2. Read the top line of numbers on the Engine Bar Code Label to determine if the engine in question falls on or within the Julian dates of 049 and 085 of 1999 (0499 to 0859). The top line is in the following format: TAYE2DDDCSSSSS T = Traceability coding (only T is used) A = Engine assembly code uniquely assigned by the engine plant (A through Z) Y = Model Year of engine (0 through 9) EE = Engine Plant code (E2 = Mound Road Engine Plant) DDD = Julian Date of build (0 through 365) C = Calendar year of build date (0 through 9). 55555 = Serial number (5 digits) from bar code label on back side of cyl. block An example would be TM9E2071 998187, this would decode as a 5.2L AN/DN automatic engine (M), built for the 1999 model year (9), produced at the Mound Road Engine Plant (E2), on day 071 of calendar year 1999 (0719 = 3/12/99), with a block serial number of 98187. This example falls within the criteria of the above symptom. 3. inspect the front facing end of the right engine valve cover for the presence of a small circular green label. The green label (dot) was installed on engines which have the new oil filter adapter plate gasket. There should be no need to replace these gaskets. 4. If the 3.9L or 5.2L engine build date is on or between Julian dates of 0499 and 0859, and a green circular label (dot) is not present on the front facing end of the right valve cover, then perform the Repair Procedure. 5. If still leaking, refer to the appropriate Service Manual for additional diagnosis.

THIS IS A COMPLETE REVISION AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS. SUBJECT: Spark Knock And Engine Oil Consumption Due To Intake Manifold Pan Gasket Oil Leak OVER VIEW: This bulletin involves the replacement of the engine intake manifold plenum pan gasket. NOTE: THIS BULLETIN APPLIES TO VEHICLE EQUIPPED WITH A 3.9L, 5.2L. OR 5.9L GASOLINE ENGINE. SYMPTOM/CONDITION: An engine intake manifold plenum pan gasket oil leak may occur on some V-6 and V-8 style engines. The oil leak is internal to the engine so no external oil leakage will be present. Two symptoms of this oil leak condition may be present. The vehicle operator may experience an engine spark knock during acceleration and/or an increase in the amount of engine oil consumed by the engine. DIAGNOSIS: Make sure Technical Service Bulletin (TSB) 18-48-98 has been performed. NOTE: IT IS IMPORTANT THAT THE COIL AND SPARK PLUG WIRES ARE ROUTED EXACTLY AS SPECIFIED IN TSB 18-48-98 TO ACHIEVE THE MOST BENEFIT. Inspect the Positive Crankcase Ventilation (PCV) valve. Shake the PCV valve to verify that the pintle inside of the PCV valve is free. Replace the PVC if the pintle is not free. If the intake manifold plenum pan gasket is leaking, an additional vacuum source will be created inside of the engine at the location of the pan gasket leakage. Engine combustion blow-by gases, oil vapor, and air from the crankcase filter/breather may be drawn past the leaking pan gasket and into the intake manifold. In most cases when this condition occurs, an engine at idle will create the highest vacuum and lowest amount of engine blow-by. 1. Allow the engine to reach normal operating temperature. 2. Stop the engine. 3. Disconnect the breather hose from the air cleaner. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Intake Manifold > Component Information > Technical Service Bulletins > Customer Interest for Intake Manifold: > 09-05-00 > Feb > 00 > Engine - Spark Knock/Oil Consumption > Page 1424 4. Attach a vacuum/pressure gauge to the end of the breather hose (Figure 1). 5. Disconnect the PCV valve hose from the intake manifold. 6. Seal off the intake manifold PCV valve hose port opening. 7. Seal off the open end of the PCV valve hose (Figure 2). NOTE: DURING THIS DIAGNOSIS, IT WOULD BE NORMAL FOR THE ENGINE TO DEVELOP PRESSURE WITHIN THE ENGINE CRANKCASE. THIS IS DUE TO THE NORMAL PROCESS OF EXHAUST BLOW-BY GASES LEAKING PAST THE ENGINE PISTON RINGS AND ACCUMULATING IN THE ENGINE CRANKCASE. DO NOT ALLOW MORE THAN 3 PSI (20.7 kpa) OF PRESSURE TO BUILD WITHIN THE ENGINE WHEN PERFORMING THE FOLLOWING DIAGNOSTIC PROCEDURE. 8. Start the warmed engine and observe the vacuum gauge. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Intake Manifold > Component Information > Technical Service Bulletins > Customer Interest for Intake Manifold: > 09-05-00 > Feb > 00 > Engine - Spark Knock/Oil Consumption > Page 1425 9.

An engine cylinder head gasket leak can be located between adjacent cylinders or between a cylinder and the adjacent water jacket. An engine cylinder head gasket leaking between adjacent cylinders is indicated by a loss of power and/or engine misfire. - An engine cylinder head gasket leaking between a cylinder and an adjacent water jacket is indicated by coolant foaming or overheating and loss of coolant. Cylinder To Cylinder Leakage Test To determine if an engine cylinder head gasket is leaking between adjacent cylinders, follow the procedures outlined in Cylinder Compression Pressure Test. An engine cylinder head gasket leaking between adjacent cylinders will result in approximately a 50-70% reduction in compression pressure. Cylinder To Water Jacket Leakage Test WARNING: Use extreme caution when the engine is operating. Do not stand in a direct line with the fan. Do not put your hands near the pulleys, belts, oft the fan. Do not wear loose clothing. Remove the radiator cap. Start the engine and allow it to warm up until the engine thermostat opens. If a large combustion/compression pressure leak exists, bubbles will be visible in the coolant. If bubbles are not visible, install a radiator pressure tester and pressurize the coolant system. If a cylinder is leaking combustion pressure into the water jacket, the tester pointer will pulsate with every combustion stroke of the cylinder. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Front Crankshaft Seal > Component Information > Service and Repair Front Crankshaft Seal: Service and Repair The oil seal can be replaced without removing the timing chain cover provided the cover is not misaligned. 1. Disconnect the negative cable from the battery. 2. Remove vibration damper. 3. If front seal is suspected of leaking, check front oil seal alignment to crankshaft. The seal installation/alignment tool 6635, should fit with minimum interference. If tool does not fit, the cover must be removed and installed properly. 4. Place a suitable tool behind the lips of the oil seal to pry the oil seal outward. Be careful not to damage the crankshaft seal bore of cover. Placing Oil Seal On Installation Tool 6635 Position Tool And Seal Onto Crankshaft 5. Place the smaller diameter of the oil seal over Front Oil Seal Installation Tool 6635. Seat the oil seal in the groove of the tool. 6. Position the seal and tool onto the crankshaft. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Front Crankshaft Seal > Component Information > Service and Repair > Page 1464 Installing Oil Seal 7.

THIS IS A COMPLETE REVISION AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS. SUBJECT: Spark Knock And Engine Oil Consumption Due To Intake Manifold Pan Gasket Oil Leak OVER VIEW: This bulletin involves the replacement of the engine intake manifold plenum pan gasket. NOTE: THIS BULLETIN APPLIES TO VEHICLE EQUIPPED WITH A 3.9L, 5.2L. OR 5.9L GASOLINE ENGINE. SYMPTOM/CONDITION: An engine intake manifold plenum pan gasket oil leak may occur on some V-6 and V-8 style engines. The oil leak is internal to the engine so no external oil leakage will be present. Two symptoms of this oil leak condition may be present. The vehicle operator may experience an engine spark knock during acceleration and/or an increase in the amount of engine oil consumed by the engine. DIAGNOSIS: Make sure Technical Service Bulletin (TSB) 18-48-98 has been performed. NOTE: IT IS IMPORTANT THAT THE COIL AND SPARK PLUG WIRES ARE ROUTED EXACTLY AS SPECIFIED IN TSB 18-48-98 TO ACHIEVE THE MOST BENEFIT. Inspect the Positive Crankcase Ventilation (PCV) valve. Shake the PCV valve to verify that the pintle inside of the PCV valve is free. Replace the PVC if the pintle is not free. If the intake manifold plenum pan gasket is leaking, an additional vacuum source will be created inside of the engine at the location of the pan gasket leakage. Engine combustion blow-by gases, oil vapor, and air from the crankcase filter/breather may be drawn past the leaking pan gasket and into the intake manifold. In most cases when this condition occurs, an engine at idle will create the highest vacuum and lowest amount of engine blow-by. 1. Allow the engine to reach normal operating temperature. 2. Stop the engine. 3. Disconnect the breather hose from the air cleaner. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Intake Manifold Gasket > Component Information > Technical Service Bulletins > Customer Interest for Intake Manifold Gasket: > 09-05-00 > Feb > 00 > Engine - Spark Knock/Oil Consumption > Page 1473 4. Attach a vacuum/pressure gauge to the end of the breather hose (Figure 1). 5. Disconnect the PCV valve hose from the intake manifold. 6. Seal off the intake manifold PCV valve hose port opening. 7. Seal off the open end of the PCV valve hose (Figure 2). NOTE: DURING THIS DIAGNOSIS, IT WOULD BE NORMAL FOR THE ENGINE TO DEVELOP PRESSURE WITHIN THE ENGINE CRANKCASE. THIS IS DUE TO THE NORMAL PROCESS OF EXHAUST BLOW-BY GASES LEAKING PAST THE ENGINE PISTON RINGS AND ACCUMULATING IN THE ENGINE CRANKCASE. DO NOT ALLOW MORE THAN 3 PSI (20.7 kpa) OF PRESSURE TO BUILD WITHIN THE ENGINE WHEN PERFORMING THE FOLLOWING DIAGNOSTIC PROCEDURE. 8. Start the warmed engine and observe the vacuum gauge. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Intake Manifold Gasket > Component Information > Technical Service Bulletins > Customer Interest for Intake Manifold Gasket: > 09-05-00 > Feb > 00 > Engine - Spark Knock/Oil Consumption > Page 1474 9.

BEFORE DISCONNECTING FUEL LINE AT FUEL RAIL, THIS PRESSURE MUST BE RELEASED. REFER TO THE FUEL SYSTEM PRESSURE RELEASE PROCEDURE . Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Page 1523 Fuel Pressure: Testing and Inspection FUEL PRESSURE LEAK DOWN TEST Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity Test. Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1-2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by: - Fuel pressure bleeding past a fuel injector(s). - Fuel pressure bleeding past the check valve in the fuel pump module. 1. Disconnect the fuel inlet line at fuel rail. Refer to Fuel Tubes/Lines/Hoses and Clamps for procedures. On some engines, air cleaner housing removal may be necessary before fuel line disconnection. 2. Obtain correct Fuel Line Pressure Test Adapter Tool Hose. Tool number 6539 is used for 5/16" fuel lines and tool number 6631 is used for 3/8" fuel lines. Connecting Adapter Tool-Typical 3. Connect correct Fuel Line Pressure Test Adapter Tool Hose between disconnected fuel line and fuel rail. 4. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test port on the appropriate Adaptor Tool. The fittings on both tools must be in good condition and free from any small leaks before performing the proceeding test. 5. Start engine and bring to normal operating temperature. 6. Observe test gauge. Normal operating pressure should be 339 kPa + 34 kPa (49.2 psi + 5 psi). 7. Shut engine off. 8. Pressure should not fall below 30 psi for five minutes. 9. If pressure falls below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is leaking. 10. Again, start engine and bring to normal operating temperature. 11. Shut engine off. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Page 1524 12. Testing for fuel injector or fuel rail leakage: Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking. 13. Testing for fuel pump cheek valve, filter/regulator check valve or fuel tube/line leakage: Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line. If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump or filter/regulator may be leaking. NOTE: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A slow loss of pressure usually indicates a defective check valve in the electric fuel pump. The electric fuel pump is not serviced separately. Replace the fuel pump module assembly. The filter/ regulator may be replaced separately on certain applications. Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for additional information. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Idle Speed > System Information > Specifications Idle Speed: Specifications Minimum Air Flow Idle ......................................................................................................................... ......................................................... 500 to 900 rpm Note: Idle speed range achieved through Minimum Air Flow Idle Test Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Idle Speed > System Information > Specifications > Page 1528 Idle Speed: Testing and Inspection The following test procedure has been developed to check throttle body calibrations for correct idle conditions.

These 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 1573 Ignition Cable: Testing and Inspection IGNITION CABLES Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and spark plugs. Terminals should be fully seated. The insulators should be in good condition and should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are cracked or torn must be replaced. Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the cables dry. Check for brittle or cracked insulation. Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable boot and spark plug. These shields protect the spark plug boots from damage (due to intense engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat shield. Testing When testing secondary cables for damage with an oscilloscope, follow the instructions of the equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as follows: CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during testing. This may cause possible heat damage to the catalytic converter. Total test time must not exceed ten minutes. With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to a good engine ground. If the cable and spark plug are in good condition, the engine rpm should drop and the engine will run poorly. If engine rpm does not drop, the cable and/or spark plug may not be operating properly and should be replaced. check engine cylinder compression. With the engine not running, connect one end of a test probe to a good ground. Start the engine and run the other end of the test probe along the entire length of all spark plug cables. If cables are cracked or punctured, there will be a noticeable spark jump from the damaged area to the test probe. The cable running from the ignition coil to the distributor cap can be checked in the same manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket. Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped, remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable. Test all spark plug cables in this manner. SPARK PLUG CABLE RESISTANCE Minimum Maximum 250 Ohms Per Inch 1000 Ohms Per Inch 3000 Ohms Per Foot 12,000 Ohms Per Foot To test ignition coil-to-distributor cap cable, do not remove the cable from the cap. Connect ohmmeter to rotor button (center contact) of distributor cap and terminal at ignition coil end of cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, remove the cable from the distributor cap. Connect the ohmmeter to the terminal ends of the cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, replace the cable. Inspect the ignition coil tower for cracks, burns or corrosion. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 1574 Ignition Cable: Service and Repair REMOVAL AND INSTALLATION Cable Removal CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap, twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off with a steady, even force. Engine Firing Order Install cables into the proper engine cylinder firing order. When replacing the spark plug and coil cables, route the cables correctly and secure in the proper retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could also cause cross ignition of the plugs or 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 between the plug cable and the distributor cap tower. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Distributor, Ignition > Distributor Cap > Component Information > Testing and Inspection Distributor Cap: Testing and Inspection Cap Inspection-External-Typical Cap Inspection-Internal-Typical Remove the distributor cap and wipe it clean with a dry lint free cloth. Visually inspect the cap for cracks, carbon paths, broken towers or damaged rotor button. Also check for white deposits on the inside (caused by condensation entering the cap through cracks). Replace any cap that displays charred or eroded terminals. The machined surface of a terminal end (faces toward rotor) will indicate some evidence of erosion from normal operation. Examine the terminal ends for evidence of mechanical interference with the rotor tip. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Distributor, Ignition > Ignition Rotor > Component Information > Testing and Inspection Ignition Rotor: Testing and Inspection Rotor Inspection-Typical Visually inspect the rotor for cracks, evidence of corrosion or the effects of arcing on the metal tip. Also check for evidence of mechanical interference with the cap. Some charring is normal on the end of the metal tip. The silicone-dielectric-varnish-compound applied to the rotor tip for radio interference noise suppression, will appear charred. This is normal. Do not remove the charred compound. Test the spring for insufficient tension. Replace a rotor that displays any of these adverse conditions. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications Spark Plug: Specifications Torque 30 ft.lb Electrode Gap 0.040 in Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1585 Spark Plug: Application and ID Plug Type ............................................................................................................................................ ....................................................................

Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in which they were removed from the engine. A single plug displaying an abnormal condition indicates that a problem exists in the corresponding cylinder. Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or oil fouled. Refer to the Spark Plug Condition. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1587 Spark Plug: Testing and Inspection SPARK PLUG CONDITIONS Normal Operation and Cold (Carbon) Fouling Normal Operating The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is evident with most grades of commercial gasoline. There will not be evidence of electrode burning. Gap growth will not average more than approximately 0.025 mm (0.001 in) per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the electrodes filed, have the gap set and then be installed. Some fuel refiners in several areas of the United States have introduced a manganese additive (MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits. Normal Operation and Cold (Carbon) Fouling Cold Fouling/Carbon Fouling Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be caused by a clogged air cleaner element or repeated short operating times (short trips). Wet Fouling or Gas Fouling A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the fouled plugs. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1588 Oil or Ash Encrusted Oil or Ash Encrusted If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of oil entry into that particular combustion chamber. Electrode Gap Bridging Electrode Gap Bridging Electrode gap bridging may be traced to loose deposits in the combustion chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be cleaned using standard procedures. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1589 Scavenger Deposits Scavenger Deposits Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is a normal condition caused by chemical additives in certain fuels. These additives are designed to change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in condition and can be cleaned using standard procedures. Chipped Electrode Insulator Chipped Electrode Insulator A chipped electrode insulator usually results from bending the center electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation can also separate the insulator from the center electrode. Spark plugs with this condition must be replaced. Preignition Damage Pre-ignition Damage Preignition damage is usually caused by excessive combustion chamber temperature. The center electrode dissolves first and the ground electrode Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1590 dissolves somewhat latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine. Determine if ignition timing is over advanced or if other operating conditions are causing engine overheating. (The heat range rating refers to the operating temperature of a particular type spark plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon the thickness and length of the center electrodes porcelain insulator.) Spark Plug Overheating Spark Plug Overheating Overheating is indicated by a white or gray center electrode insulator that also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug overheating. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1591 Spark Plug: Service and Repair Heat Shields Spark plug cable beat shields are pressed into the cylinder head to surround each cable boot and spark plug. If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides of shield for removal. Each shield is slotted to allow for compression and removal. To install the shields, align shield to machined opening in cylinder head and tap into place with a block of wood. PLUG REMOVAL 1. Remove engine cover. Cable Removal 2. Always remove spark plug or ignition coil cables by grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady motion. Never pull directly on the cable. Internal damage to cable will result. 3. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area around the spark plug. This will help prevent foreign material from entering the combustion chamber. 4. Remove the spark plug using a quality socket with a rubber or foam insert. 5. Inspect the spark plug condition. Refer to Spark Plug Condition. PLUG CLEANING The plugs may be cleaned using commercially available spark plug cleaning equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before adjusting gap. CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will remain on the spark plug insulator and will cause plug misfire. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1592 PLUG GAP ADJUSTMENT Setting Spark Plug Gap-Typical Check the spark plug gap with a gap gauge tool. If the gap is not correct, adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center electrode. SPARK PLUG GAP 1.01 mm (0.040 in). PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged. Always tighten spark plugs to the specified torque.. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator. When replacing the spark plug and ignition coil cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground. 1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark plugs to 35-41 Nm (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications Compression Check: Specifications Compression should not be less than 689 kPa (100 psi) and not vary more than 172 kPa (25 psi) from cylinder to cylinder.

The recommended mixture of 50/50 ethylene-glycol and water will provide protection against freezing to -37° C (-35° F). The antifreeze concentration must always be a minimum of 44%, year round, in all climates. If percentage is lower than 44%, 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. 100 Percent Ethylene-Glycol Should Not Be Used Use of 100 Percent Ethylene-Glycol will cause formation of additive deposits in the system, as the corrosive inhibitive additives in ethylene-glycol require the presence of water to dissolve. The deposits act as insulation, causing temperatures to rise 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 % ethylene-glycol freezes at 22° C (-8° F). Propylene-Glycol Formulations Should Not Be Used Propylene-glycol formulations do not meet the required specifications. 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 degrees 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 and freeze up. Propylene-Glycol also has a poorer heat transfer characteristics than ethylene-glycol. This can increase cylinder head temperatures under certain conditions. Propylene-Glycol/Ethylene-Glycol Mixtures Should Not Be Used Propylene-glycol/ethylene-glycol mixtures can cause the destabilization of various corrosion inhibitors, causing damage to the coling system components. Also, once ethylene-glycol and propylene-glycol based coolants are mixed in the vehicle, conventional methods of determining the freeze point will not be accurate. Both the refractive index and specific gravity differ between the ethylene-glycol and propylene-glycol. CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can cause problems associated with 100 percent ethylene-glycol. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Coolant > Component Information > Specifications > Page 1616 Coolant: Service Precautions DO NOT mix green colored coolant with orange colored coolant. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Coolant > Component Information > Description and Operation > Coolant Performance Coolant: Description and Operation Coolant Performance ETHYLENE-GLYCOL MIXTURES The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle open ating conditions.

This noise is created by a large cooling fan that is required to provide optimum cooling for low vehicle speed operation in hot weather conditions and for heavy trailer towing. Since the large cooling fan is unnecessary in most operating conditions, these vehicles are also equipped with viscous fan drives that allow the fan to operate at variable speeds based upon temperature loads. The viscous fan drive will engage the fan for maximum cooling when temperatures are high and allow the fan to operate at slower speeds when temperatures are low. In addition, at engine start-up, the viscous fan drive engages the fan for maximum cooling until the fluid in the viscous clutch can dissipate out of the clutch drive grooves allowing the fan to operate at a slower speed. Because of the viscous fan drive, the noise may occur during high temperature conditions and for the first 1-2 minutes of operation. Due to the roar of the fan, customers may also complain of a perceived loss of power, automatic transmission slippage, or that the transmission is slaying into a low gear too long (delayed upshift). Customers concerned about this noise should be advised that this condition is normal and no repair attempts should be made.

This noise is created by a large cooling fan that is required to provide optimum cooling for low vehicle speed operation in hot weather conditions and for heavy trailer towing. Since the large cooling fan is unnecessary in most operating conditions, these vehicles are also equipped with viscous fan drives that allow the fan to operate at variable speeds based upon temperature loads. The viscous fan drive will engage the fan for maximum cooling when temperatures are high and allow the fan to operate at slower speeds when temperatures are low. In addition, at engine start-up, the viscous fan drive engages the fan for maximum cooling until the fluid in the viscous clutch can dissipate out of the clutch drive grooves allowing the fan to operate at a slower speed. Because of the viscous fan drive, the noise may occur during high temperature conditions and for the first 1-2 minutes of operation. Due to the roar of the fan, customers may also complain of a perceived loss of power, automatic transmission slippage, or that the transmission is slaying into a low gear too long (delayed upshift). Customers concerned about this noise should be advised that this condition is normal and no repair attempts should be made.

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. A thermostatic bi-metallic 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. CAUTION: Engines equipped with serpentine drive belts have reverse rotating fans and viscous fan drives. They are marked with the word REVERSE to designate their usage. Installation of the wrong fan or viscous fan drive can result in engine overheating. CAUTION: If the viscous fan drive is replaced because of mechanical damage, the cooling fan blades should also be inspected. Inspect for fatigue cracks, loose blades, or loose rivets that could have resulted from excessive vibration. Replace fan blade assembly if any of these conditions are found. Also inspect water pump bearing and shaft assembly for any related damage due to a viscous fan drive malfunction. NOISE NOTE: It is normal for fan noise to be louder (roaring) when: Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Fan Clutch > Component Information > Technical Service Bulletins > Page 1643 ^ The underhood temperature is above the engagement point for the viscous drive coupling. This may occur when ambient (outside air temperature) is very high. ^ Engine loads and temperatures are high such as when towing a trailer. ^ Cool silicone fluid within the fan drive unit is being redistributed back to its normal disengaged (warm) position. This can occur during the first 15 seconds to one minute after engine start-up on a cold engine. LEAKS Viscous fan drive operation is not affected by small oil stains near the drive bearing. If leakage appears excessive, replace the fan drive unit. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Fan Clutch > Component Information > Technical Service Bulletins > Page 1644 Fan Clutch: Testing and Inspection VISCOUS FAN DRIVE TESTING If the fan assembly free-wheels without drag (the fan blades will revolve more than five turns when spun by hand), replace the fan drive. This spin test must be performed when the engine is cool. For the following test, the cooling system must be in good condition. It also will ensure against excessively high coolant temperature. WARNING: BE SURE THAT THERE IS ADEQUATE FAN BLADE CLEARANCE BEFORE DRILLING. 1. Drill a 3.18-mm (1/8-in) diameter hole in the top center of the fan shroud. 2. Obtain a dial thermometer with an 8 inch stem (or equivalent). It should have a range of -18° to 105°C (0° to 220°F). Insert thermometer through the hole in the shroud. Be sure that there is adequate clearance from the fan blades. 3. Connect a tachometer and an engine ignition timing light (timing light is to be used as a strobe light). 4. Block the air flow through the radiator. Secure a sheet of plastic in front of the radiator (or air conditioner condenser). Use tape at the top to secure the plastic and be sure that the air flow is blocked. 5. Be sure that the air conditioner (if equipped) is turned off. WARNING: USE EXTREME CAUTION WHEN THE ENGINE IS OPERATING. DO NOT STAND IN A DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING. 6. Start the engine and operate at 2400 rpm. Within ten minutes the air temperature (indicated on the dial thermometer) should be up to 88° C (190° F). Fan drive engagement should have started to occur at between 74° to 82° C (165° to 180° F). Engagement is distinguishable by a definite increase in fan flow noise (roaring). The timing light also will indicate an increase in the speed of the fan. 7. When the air temperature reaches 88° C (190° F), remove the plastic sheet. Fan drive disengagement should have started to occur at between 57° to 79° C (135° to 175° F). A definite decrease of fan flow noise (roaring) should be noticed. If not, replace the defective viscous fan drive unit. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Fan Clutch > Component Information > Technical Service Bulletins > Page 1645 Fan Clutch: Service and Repair VISCOUS FAN DRIVE Refer to Fan Blade for removal and installation procedures of the viscous drive unit.

The sensor provides an input voltage to the powertrain control module (PCM) relating coolant temperature. The PCM uses this input along with inputs from other sensors to determine injector pulse width and ignition timing. As coolant temperature varies, the coolant temperature sensor resistance will change. This change in resistance results in a different input voltage to the PCM. When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air-fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 1654 Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection COOLANT TEMPERATURE SENSOR To perform a complete test of the engine coolant temperature sensor and its circuitry, refer to DRB scan tool and appropriate Powertrain Diagnostics Procedures.

It is called a combination coil because it combines the functions of a heater core and an evaporator coil into a single heat exchanger unit. The combination coil features six rows of tube and fin construction. The two rows located toward the outboard side of the vehicle serve as the heater core and have engine coolant circulated through them whenever the rear water valve is open. The four rows toward the inboard side of the vehicle serve as the evaporator and have refrigerant circulated through them whenever the air conditioning compressor is operating. The amount of refrigerant flowing through the combination coil is controlled by a dedicated rear thermal expansion valve. The combination coil can be accessed for service by removing the rear heater-A/C unit upper housing. The combination coil cannot be repaired and, if faulty or damaged, it must be replaced. Heater Core Front The heater core is located in the heater-A/C housing, on the right side of the engine compartment. It is a heat exchanger made of rows of tubes and fins. Engine coolant is circulated through heater hoses to the heater core whenever the front water valve is open. As the coolant flows through the heater core, heat removed from the engine is transferred to the heater core fins and tubes. Air directed through the heater core picks up the heat from the heater core fins. The blend air door allows control of the heater output air temperature by controlling how much of the air flowing through the heater-A/C housing is directed through or around the heater core. The blower motor speed controls the volume of air flowing through the heater-A/C system. The heater core cannot be repaired and, if faulty or damaged, it must be replaced. Rear Models equipped with the optional rear heater-A/C unit have a combination coil located within the rear unit housing. The combination coil functions as both the rear heater core and the rear evaporator coil. See Combination Coil above for more information. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Heater Core > Component Information > Service and Repair > Heater Core Removal and Installation Heater Core: Service and Repair Heater Core Removal and Installation Front Heater Core FRONT HEATER CORE REMOVAL 1.

The pressure relief point (in pounds) is engraved on top of 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 that opens when system pressure reaches release range of 97-138 kPa (14-20 psi). A vent valve in the center of cap allows a small coolant flow through cap when coolant is below boiling temperature. The valve is completely closed when boiling point is reached. 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 tank to be drawn through its connecting hose into radiator. If the vacuum valve is stuck shut, the radiator hoses will collapse on cool down. Clean the vent valve. A rubber gasket seals radiator filler neck to prevent leakage. This is done to keep system under pressure. It also maintains vacuum during coolant cool-down allowing coolant to return from reserve/ overflow tank. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cap > Component Information > Testing and Inspection > Radiator Cap - Pressure Testing Radiator Cap: Testing and Inspection Radiator Cap - Pressure Testing PRESSURE TESTING Pressure Testing Radiator Cap Remove cap from radiator. Be sure that sealing surfaces are clean. Moisten rubber gasket with water and install cap on pressure tester 7700 or an equivalent. Operate tester pump to bring pressure to 104 kPa (15 psi) on gauge. If pressure cap fails to hold pressure of at least 97 kPa (14 psi) replace cap. The pressure cap may test properly while positioned on tool 7700 (or equivalent). It may not hold pressure or vacuum when installed on radiator. If so, inspect radiator filler neck and cap's top gasket for damage. Also inspect for dirt or distortion that may prevent 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. Radiator Pressure Cap And Filler Neck-Typical INSPECTION Hold cap at eye level, right side up. The vent valve at bottom of cap should open. If rubber gasket has swollen and prevents vent valve from opening, replace cap. Hold cap at eye level, upside down. If any light can be seen between vent valve and rubber gasket, replace cap. Do not use a replacement cap that has a spring to hold vent shut. 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 radiator. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cap > Component Information > Testing and Inspection > Radiator Cap - Pressure Testing > Page 1689 Radiator Cap: Testing and Inspection Radiator Cap to Filler Neck Seal - Pressure Relief Check RADIATOR CAP-TO-FILLER NECK SEAL PRESSURE RELIEF CHECK The pressure cap upper gasket (seal) pressure relief can be tested by removing overflow hose from radiator filler neck nipple.

The sensor provides an input voltage to the powertrain control module (PCM) relating coolant temperature. The PCM uses this input along with inputs from other sensors to determine injector pulse width and ignition timing. As coolant temperature varies, the coolant temperature sensor resistance will change. This change in resistance results in a different input voltage to the PCM. When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air-fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Sensors and Switches - Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 1700 Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection COOLANT TEMPERATURE SENSOR To perform a complete test of the engine coolant temperature sensor and its circuitry, refer to DRB scan tool and appropriate Powertrain Diagnostics Procedures.

The wax pellet is located in a sealed container at spring end of thermostat. When heated, the pellet expands, overcoming closing spring tension and water pump pressure to force valve to open. Coolant leakage into pellet container will cause thermostat to fail in open position. Do not attempt to free a sticking thermostat with a prying device. The thermostat controls the operating temperature of the engine by controlling the amount of coolant flow to radiator. On all engines, the thermostat is closed below 88°C (192°F). When coolant reaches this temperature, thermostat begins to open allowing coolant flow to radiator. This provides quick engine warm-up and overall temperature control. The thermostat is designed to provide a minimum engine operating temperature range of from 88 to 93°C (192 to 199°F). The thermostat should be fully open for maximum coolant flow during operation in hot ambient temperatures of approximately 104°C (220°F). Above 104°C (220°F), coolant temperature is controlled by radiator, fan and ambient temperature. An arrow, plus the word UP is stamped on front flange next to air bleed. The words TO RAD are stamped on one arm of thermostat. They indicate proper installed position. The same thermostat is used for winter and summer seasons. CAUTION: Do not operate an engine without a thermostat, except for servicing or testing. An engine should not be operated without a thermostat, except for servicing or testing. Operating without a thermostat causes longer engine warm-up time, unreliable warm-up performance, increased exhaust emissions and crankcase condensation that can result in sludge formation. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Thermostat, Engine Cooling > Component Information > Specifications > Page 1710 Thermostat: Service and Repair REMOVAL WARNING: DO NOT LOOSEN THE RADIATOR DRAINCOCK OR CAP WITH THE SYSTEM HOT AND PRESSURIZED.

Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System Body Control Module: Description and Operation Airbag System Airbag System Description AIRBAG SYSTEM The Airbag Control Module (ACM) is secured to a bracket on the floor panel below the drivers seat. The ACM contains a microprocessor, the impact sensor, and energy storage capacitor. The microprocessor contains the airbag system logic. The ACM system logic includes On-Board Diagnostics (OBD) capability, and communicates with the instrument cluster circuitry on the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor in the ACM monitors the impact sensor signal and the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster on the CCD data bus to turn on the airbag indicator lamp. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbag system components. Only one impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags, for one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. The airbag warning lamp is the only point at which the customer can observe "symptoms" of a system malfunction, Whenever the ignition key is turned to the RUN or START position, the MIC performs a lamp check by turning the AIRBAG warning lamp ON for 6-8 seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the system or the MIC lamp circuit may be internally shorted to ground. If the lamp comes ON and stays ON for a period longer than 6-8 seconds then goes OFF, there is usually an intermittent problem in the system. The MIC monitors the airbag warning lamp and seat belt warning lamp during the bulb check for a defective bulb or lamp driver circuit. The MIC tests the airbag lamp during the cluster bulb check and substitutes the seat belt lamp if the airbag lamp is defective. If the airbag lamp is defective the MIC will turn the seat belt light ON and OFF approximately 30 times to warn the driver that the airbag lamp is defective. The lamp status is sent to the ACM continuously via a CCD bus message. The seat belt lamp acts as a backup in the event that the AIRBAG lamp is defective. This information is sent to the ACM continuously via a CCD bus message. Perform the WARNING LAMP BULB OR DRIVER procedure in this book to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated with no active DTC's The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. Service and general information labels about the airbag system can be found on the driver's sun visor, the glove box door, and in the engine compartment.

Passenger Airbag Module (PAB) PASSENGER AIRBAG MODULE (PAB) The airbag door in the instrument panel top cover above the glove box is the most visible part of the passenger side airbag system. Located under the airbag door is the airbag cushion and it's supporting components. The airbag module includes a housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator includes a small canister of highly compressed argon gas. The inflator seals the hold in the airbag cushion so it can discharge the compressed gas it contains directly into the cushion when supplied with the proper electrical signal. The airbag door has a living hinge at the top, which is secured to the instrument panel top cover. The door also has predetermined breakout lines concealed beneath its decorative cover. Upon airbag deployment the airbag door will split at the breakout lines and the door will pivot out of the way. The airbag module is secured at the bottom to the steel structural base of the instrument panel above the glove box opening. The airbag door is serviced as a unit with the passenger side airbag module, and includes the two passenger heating and air conditioning panel outlet housings. Following an airbag deployment, the airbag module and the instrument panel assembly must be replaced. Passenger Airbag On/Off Switch PASSENGER AIRBAG ON/OFF SWITCH The passenger side airbag ON/OFF switch is located on the instrument panel. To de-activate the passenger side airbag, turn the key actuator switch from the horizontal position to a slanted position (pointing to the "OFF" light indicator), approximately 45 degrees clockwise from the "ON" position. Rotating the key actuator switch 45 degrees clockwise, remove the key completely from the switch and verify that the switch actuator hole stays in the new position (45 degrees clockwise from horizontal). The switch is spring loaded to the "ON" position. It will return to the "ON" position unless you remove the key. When the IGNITION in ON, this procedure will illuminate the "OFF" light indicator on the passenger airbag ON/OFF switch. To re-enable the passenger side airbag, reverse the procedure above so that the key switch actuator is returned to a horizontal position. NOTE: DO NOT TURN IGNITION ON WITH KEY IN SWITCH. DO NOT TURN SWITCH WITH IGNITION ON. DO NOT LEAVE KEY IN SWITCH. THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG ON/OFF SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED.

While the vehicle is off the illuminated entry feature can be activated in the following ways. Whenever a door is opened - When the vehicle is unlocked with a key - When the CTM receives a valid unlock signal from the RKE transmitter The illuminated entry will remain ON for 30 seconds after the last door is closed, turn OFF immediately after ignition is turned ON, or turn OFF when the CTM receives a LOCK message from the RKE transmitter. 15 Minute Illumination Timeout If the ignition is OFF and either front door is open, interior illumination will terminate after 15 minutes. If either front door is open and the ignition is turned in the RUN or ACCESSORY position, interior illumination will continue until the ignition is turned OFF. Once the ignition is OFF, if either front door remains open, the 15 minute interior illumination timeout will begin. Note: This timeout feature does not apply to either auxiliary door or the dome lamp switch which are hardwired to the courtesy lamps. The auxiliary door switches are also wired to the CTM to operate illuminated entry. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 1770 Body Control Module: Description and Operation Central Timer Module CENTRAL TIMER MODULE (CTM) The AB RAM VAN has two different body electrical systems, High Line and Base. The High Line utilizes a Central Timer Module (CTM) to provide the body features listed below. The CTM was designed to reduce cost, wiring complexity, and improve the system reliable. The CTM interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of information between modules and diagnostic capability using the DRB III. The CTM equipped vehicles can be identified by the sound of a Key-In Ignition CHIME. The Base AB RAM VAN body system is composed of individual modules. Because the stand-alone modules do not communicate on the CCD Bus, they cannot be diagnosed using the DRB. For concerns about the BASE AB VAN, refer to the appropriate service procedures. The Base version can be identified by the sound of the Key-In Ignition BUZZER. The CTM provides the following features: CCD Bus Communication - Chime - Courtesy Lamp Controls/Illuminated Entry - Enhanced Accident Response - Intermittent Wiper Delay - Power Door Locks W/RKE - Remote Keyless Entry (RKE) - Speed Sensitive Intermittent Wipers - Vehicle Theft Security System (VTSS) The module is located on the left center instrument panel support.

The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for gauge problems and tell tale warnings. The CTM chime functions will have priority over the MIC chime requests. There are two chime rates, Low; 50 chimes per minute for reminders and High; 180 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the driver door is open or the headlights are left ON. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for the key-in, and headlamp warning, as long as the drivers door is open. The seat belt warning chime is activated for 4 to 6 seconds , and all other chime conditions will activate the chime once at the same time the warning light ON the cluster is illuminated. The chime will sound for the following conditions: High rate Key in Warning ignition off, key in ignition, driver's door open - Ignition off, headlamps ON, driver's door open Low rate Seat belt warning - 6 seconds after key on (6 to 8 chimes) or until seatbelt is buckled - Airbag lamp illuminated (3 times after prove-out) - ABS lamp illuminated (2 chimes after prove-out if equipped) - Check engine lamp illuminated (2 chimes after prove-out) - Check gauges lamp illuminated (2 chimes) - Engine Temp High - when gauge enters red zone (2 chimes) - Low fuel - when fuel level reaches 1/8 tank (2 chimes) - Low washer fluid (2 chimes) - Transmission Temperature High (2 chimes) If the ignition switch is turned to the RUN/START position and the driver's door is closed, then opened, the warning chime is defeated. This allows the doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the OFF position, then normal function will be restored. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 1772 Body Control Module: Description and Operation Airbag System Description AIRBAG SYSTEM The Airbag Control Module (ACM) is secured to a bracket on the floor panel below the drivers seat.

The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for the key-in, and headlamp warning, as long as the drivers door is open. The seat belt warning chime is activated for 4 to 6 seconds , and all other chime conditions will activate the chime once at the same time the warning light ON the cluster is illuminated. The chime will sound for the following conditions: High rate Key in Warning ignition off, key in ignition, driver's door open - Ignition off, headlamps ON, driver's door open Low rate Seat belt warning - 6 seconds after key on (6 to 8 chimes) or until seatbelt is buckled - Airbag lamp illuminated (3 times after prove-out) - ABS lamp illuminated (2 chimes after prove-out if equipped) - Check engine lamp illuminated (2 chimes after prove-out) - Check gauges lamp illuminated (2 chimes) - Engine Temp High - when gauge enters red zone (2 chimes) - Low fuel - when fuel level reaches 1/8 tank (2 chimes) - Low washer fluid (2 chimes) - Transmission Temperature High (2 chimes) If the ignition switch is turned to the RUN/START position and the driver's door is closed, then opened, the warning chime is defeated. This allows the doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the OFF position, then normal function will be restored. Description and Functional Operation DESCRIPTION AND FUNCTIONAL OPERATION The body system on the 1999 AB HIGH LINE consists of three modules that communicate over the CCD bus (Chrysler Collision Detection multiplex system). There are two additional modules, the Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are performed through the Serial Communication Interface of SCI, the same as previous years. All of the information about the functioning of all the system is organized, controlled, and communicated by (CCD Bus). Through the CCD bus, information about the operation of vehicle components and circuits is relayed quickly to the appropriate module(s). All modules receive all the information transmitted on the bus even though a module may not require all the information to perform it's function. It will only respond to messages "addressed" to it through a binary coding process. This method of data transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. DRB III Error Messages and Blank Screen DRB III ERROR MESSAGES AND BLANK SCREEN Under normal operation, the DRB will display one of only two error messages: User-Requested WARM Boot or - User-Requested COLD Boot If the DRB should display any other error message, record the entire display and call the MDS Hotline, or call for information and assistance at 1-800-825-8737. This is a sample of such an error message display: ver: 2.14 date: 26 Jul93 file: key_itf.cc date: Jul 26 1993 line: 548 err: Ox1 User-Requested COLD Boot Press MORE to switch between this display and the application screen. Press F4 when done noting information. DRB III Does Not Power Up (Blank Screen) If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (Data Link Connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, and inoperative DRB may be the result of a faulty cable or vehicle wiring. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 1776 DRB III Scan Tool Display Is Not Visible Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition. Enhanced Accident Response (Highline CTM Only) ENHANCED ACCIDENT RESPONSE (Highline Only) If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The interior lights will be turned ON 10 seconds after getting zero speed message on the CCD bus. In addition to unlocking the doors, the lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "OFF" position, normal operation will resume. Diagnostics DIAGNOSTICS Gauges The instrument cluster will not store any DTC's. Because the engine controller PCM gathers all the gauge information and sends it to the cluster via the bus, it is the controller's responsibility to monitor these inputs and store DTC's for them. For this reason the first item to be checked regarding a gauge problem (except oil pressure) should be the engine controller for any DTC's relating to the gauge in question. There are DTC's associated with all the gauges except for the oil pressure gauge. When diagnosing gauges, the input that is used for gauge message (fuel level sender for example) must be valid. Because of OBD II requirements, most of the information used for monitoring the OBD II system happens to be the same information used by the controller to formulate the gauge bus messages. OBD II requirement state that the fuel level sender must be checked for rationality. This includes determining if the sending unit voltage is too high or too low or if the voltage hasn't changed over time. If the PCM has determined that the sender information isn't valid, it will send a diagnostic trouble code. The presence or absence of the fuel level sending code in the PCM is an important factor to determine whether a fuel gauge problem is in the sending unit or the cluster. The same situation is used in all cluster diagnostics related to gauge operation with the exception of the oil pressure gauge. OBD II requirements do not include oil pressure monitoring. Therefore, oil pressure diagnostic would dictate that a mechanical oil pressure gauge be attached to the engine for absolute verification of oil pressure readings. Hard Wired Lamps The cluster contains several hard wired lamps described earlier. The lamps are set up in two configurations. Either the cluster supplies power and ground is supplied by the circuit being monitored or the lamp is supplied ground by the cluster and power comes from a module or other device. Refer to the schematic for the specific details on the lamp in question. Verification of the bulb filament may be required in cases of an inoperative lamp. This will require removal of the cluster and bulb in question. NOTE: THE BRAKE, TRANS TEMP, CHECK GAUGES, SEAT BELTS AND AIRBAG WARNING LAMPS ARE LED'S, ALL OTHER ARE BULBS. IF ANY LED'S ARE DEFECTIVE,THE INSTRUMENT CLUSTER MUST BE REPLACED. CCD Controlled Lamps The cluster contains several CCD controlled lamps as described earlier. These lamps are part of the diagnostic self-test. When entering the self-test mode, operation of these lamps can be observed. If the bulb fails to operate during the self-test and the bulb filament is good, the cluster assembly will need to be replaced. NOTE: A FLASHING SEAT BELT LAMP INDICATES THAT THE AIRBAG WARNING LAMP IS NOT OPERATING PROPERLY. Mechanical Instrument Cluster Description MECHANICAL INSTRUMENT CLUSTER (MIC) Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 1777 The Ram Van uses a standard MIC in all of it's U.S. vehicles. The cluster has 5 gauges and 15 indicator lamps. The gauges are positioned with information received over the CCD bus. Some of the indicator lamps are hardwired and the cluster using CCD bus information controls some. The MIC is hardwired to the CTM to provide the warning lamp announcement chimes. There is a self-test available for the cluster that will actuate all the gauges to their calibration points. The self test will not run if the cluster sees engine RPM or vehicle speed. The test will light all CCD controlled lamps for verification of lamp operation. It also forces the odometer Liquid Crystal Display (LCD) to perform a segment check. The self test routine can be entered by pressing and holding the trip reset button while rotating the ignition key from the OFF position to the ON position. When the word "check" appears, release the button and the test will continue. The cluster will provide bus bias termination and the engine controller provides a second termination. If the cluster is disconnected, the bus will not be biased. The cluster will be serviced as an assembly. There will be limited parts available, bulbs and sockets, the front lens, the trip odometer system cover and the rear cover assembly. No internal parts of the cluster will be serviceable. Normal Operation At key ON, the cluster will light the low fuel, seat belt, check gauges, and airbag. As the key is turned farther towards the start position, the check engine, ABS (if equipped) and brake warning lamp will illuminate. The liquid crystal display (LCD) will indicate the mileage stored inside the cluster. If there is a bus failure and the cluster cannot receive distance pulses from the engine controller, the cluster will display the last mileage stored until the ignition is turned OFF. If the cluster is receiving bus messages but is unable to display odometer information because of an internal failure, the odometer display will be blank. Dimming is handled by the potentiometer that controls instrumentation illumination. Lamps (Hardwired) The following lamps are hardwired in the cluster and are not part of the self-test. High Beam - Left Turn Signal - Right Turn Signal - Brake (comes ON during self-test) - Low Wash (comes during self-test) - Seat Belt (comes ON during self-test) Lamps (CCD) The cluster via CCD messages controls the following lamps. They are actuated during the self-test procedure. ABS lamps - Airbag - Check Engine - Check Gauges - Cruise Control Lamp - Security - Trans Temp - O/D OFF - Low Fuel Warning - Internally controlled by the cluster; not CCD NOTE: THE TURN SIGNALS, HIGH BEAM INDICATOR, SEAT BELT WARNING LAMP,LOW WASHER WARNING LAMP, AND BRAKE WARNING LAMP ARE HARDWIRED TO THE CLUSTER. Power Door Lock System POWER DOOR LOCKS The CTM controls the door lock actuation assemblies to handle locking and unlocking with the interior door lock switches or the RKE transmitter (key fob). There is also a door lock inhibit feature that prevents the power locking of the doors if the key is in the ignition or the headlamps are ON and the left front door is open. However, the doors can still be locked using the RKE transmitter which allows the engine to run for warm up purposes. Automatic (Rolling) Door Locks When the doors are closed and the vehicle speed exceeds 15 MPH due to engine power (not just rolling) and all doors are closed, the CTM will lock the doors. The vehicle is shipped with the automatic door lock feature disabled, but may be enabled using the DRB. Door Lock Delay If the CTM receives a signal to lock the doors and one or both of the auxiliary doors (side or rear) are open, the front doors will still lock. Five seconds after both of the auxiliary door are closed, the CTM will recycle the lock function. Remote Keyless Entry The CTM is compatible with a two button TRW RKE transmitter (keyfob). Two pre-programmed transmitters will be supplied with each vehicle. The CTM is capable of retaining up to four transmitters which can be programmed using the DRB. When a signal encoded with the correct vehicle access code is received and contains a valid message, the CTM will activate the corresponding relay to lock or unlock the doors. When an unlock Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 1778 message is sent, all the doors will unlock, the VTSS will disarm and the illuminated entry will be activated. When a lock message is sent and all the doors are closed, all the doors will lock, the VTSS arming sequence will begin and the illuminated entry will turn OFF. Horn chirp When the doors are locked using the transmitter, a horn chirp will sound to let the customer know the doors were locked. The vehicle will be shipped with this function disabled but may be enabled using the DRB. The duration of the horn chirp can also be changed using the DRB. Trouble Codes AIRBAG DIAGNOSTIC TROUBLE CODES Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists, diagnostic priority should be given to the active codes. Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the trouble codes. It is not necessary to perform all of the tests in this book to diagnose an individual code. Always begin by reading the diagnostic trouble codes using the DRB III. This will direct you to the specific test(s) that must be performed Active diagnostic trouble codes for the airbag system are not permanent and will change the moment the reason for the code is corrected. In certain test procedures within this , diagnostic trouble codes are used as a diagnostic tool. Active Codes The code becomes active as soon as the malfunction is detected or key-OFF, whichever occurs first. An active trouble code indicates an on-going malfunction. This means that the defect is currently there every time the airbag control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected. With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present. The seat belt lamp replaces the airbag lamp if the airbag lamp is defective. The seat belt lamp pulses ON and OFF 30 times if the airbag warning lamp is defective. Stored Codes Airbag codes are automatically stored in the ACM's memory as soon as the malfunction is detected. The exception is the "Loss of Ignition Run Only" code which is an active code only. A "stored" code indicates there was an active code present sometime. However, the code currently may not be present as an active code, although another active code could be. When a trouble code occurs, the airbag warning lamp illuminates for 12 seconds minimum (even if the problem existed for less than 12 seconds). The code is stored, along with the time in minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. The minimum time shown for any code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two minutes 13 seconds, for example, would be three minutes. If malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored code. If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the problem. In this case, the stored code can indicate an area to inspect. If no obvious problems are found, erase stored codes, and with the ignition "ON" wiggle the wire harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes periodically as you work through the system. This procedure may uncover a malfunction that is difficult to locate. Airbag Trouble Codes The Airbag Control Module may report any of the following diagnostic trouble codes. For the following codes, replace the Airbag Control Module (ACM) even if set intermittently: ACM ACCELEROMETER - ACM OUTPUT DRIVER CIRCUIT OPEN - ACM INTERNAL DIAGNOSTIC CODE # 1 - ACM INTERNAL DIAGNOSTIC CODE # 2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 1779 - ACM STORED ENERGY - ACM OUTPUT DRIVER For these codes, refer to the appropriate diagnostic procedure: Cluster Message Mismatch Driver Squib Circuit Open Driver Squib Circuit Shorted Driver Squib Circuit Shorted to Battery Driver Squib Circuit Shorted to Ground Loss of Ignition Run Only Loss of Ignition Run/Start NO Cluster CCD Message No CCD Communication Passenger Squib Circuit Open Passenger Squib Circuit Shorted Passenger Squib Circuit Shorted to Battery Passenger Squib Circuit Shorted to Ground Warning Lamp Open/Shorted Vehicle Communication VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the higher priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus -" (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a voltage divider network located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems use more than one. Some modules are capable of biasing and terminating the bus by themselves. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. Without termination, voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. In the 1999 Ram Van, the instrument cluster supplies bus bias and termination and the PCM supplies an additional point of termination. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLES ON-BOARD DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING.IF THERE IS A PROBLEM, REFER TO THE VEHICLE COMMUNICATION. Vehicle Theft Security System (VTSS) VEHICLE THEFT SECURITY SYSTEM (VTSS) The VTSS will monitor the states of the ignition, door lock signal, and all other doors to alert against unauthorized entry into the vehicle. The VTSS will be enabled at the assembly plant. To prevent arming of the VTSS during assembly and the shipping process, the vehicle must be started 20 times before the VTSS will operate properly. Arming the VTSS To arm the system, the ignition must be OFF and all doors must be closed and locked using either the power door lock switches or the RKE transmitter. Using a key or pressing the mechanical lock soldier will not initiate arming the VTSS. The delay lock feature will delay the arming process until all doors are closed. Once the VTSS begins to arm, the CTM will activate the security lamp output at a 1 Hz rate. During this process the arming process will terminate if the ignition is turned ON, if a door is opened, if the doors are unlocked using the door lock switch or the RKE transmitter, or if the front doors are unlocked using the key. After fifteen seconds of the arming process, the security lamp will go OFF and the VTSS will be armed. Once the vehicle is armed the ignition may be turned to the accessory position (to listen to radio, etc.) without triggering the alarm. The VTSS can only be disarmed using the key or the RKE transmitter. Triggering the VTSS Once the VTSS is armed, the alarm will trigger if any of the doors are opened or if the key is turned the Run/Start position. When triggered, the CTM will instruct the PCM to turn OFF the engine after two seconds and will pulse the horn and headlamps at a specified duty cycle and frequency. The audible (horn) warning will continue for three minutes then terminate. The visual (headlamps) warning will continue for fifteen additional minutes then terminate. The engine will continue to start and quit until the VTSS is disarmed. Tamper Alert If the VTSS was triggered during the last armed period, the next time it is disarmed the CTM will activate three horn chirps. To determine what caused the alarm to be tripped, using the DRB select "Theft Alarm" "Monitor Display" and observe: "Alarm Tripped by". This is a great tool to Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 1780 use when a customer complains that the alarm went OFF and cannot determine what triggered it. Warnings WARNINGS Vehicle Damage Warnings Before disconnecting any control module, make sure the ignition is OFF. Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected. Road Testing A Complaint Vehicle Some complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic code or symptom condition. CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE REASSEMBLED DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB SCREEN WHILE IN MOTION.DO NOT HANG THE DRB FROM THE REAR VIEW MIRROR OR OPERATE IT YOURSELF.HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB. Wiper System WINDSHIELD WIPERS Feature Description The Ram Van equipped with a CTM will utilize speed sensitive intermittent wipe and wipe after wash function. The driver selects the Wiper function via a Steering Column mounted Stalk Switch. The Wiper system is operational whenever the ignition switch is in the Run or Accessory positions only (not during engine crank). The low and high speeds are controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as selected by the driver, and immediate wipe of the windshield takes place and the new delay interval is implemented. An Intermittent Wipe cycle consists of operating the Wipers in the Low Speed mode for one cycle, then executing a delay time. The delay time available to the driver is adjustable from 1/2 second to 18 seconds. Speed Sensitive Intermittent Wipe Operation Speed Intermittent Wipe is operational whenever the Ignition Switch is in either the RUN or ACCESSORY positions, and the voltage ON the CKT name input is greater than 4.5 VDC. The resistance selected by the stalk switch is used to set the delay time between wipe cycles. The Intermittent Wipe Delay Time is also adjusted based upon Vehicle Speed. When the Vehicle Speed is < 10 MPH then the driver selected Delay Time is doubled providing a range from 1 second to 36 seconds. When the vehicle speed is > 10 MPH then the driver selected Delay Time is not adjusted. An immediate Low Speed mode Wipe cycle will occur and a new Delay Time interval will start if the driver changes the current selected Delay Time to a shorter interval. The speed signal is provided to the CTM from the PCM over the CCD bus. Wipe after Wash Operation Wipe after Wash operation activates the Wiper system when the Wash button is pressed. Wiper after Wash operation is available while the wiper switch is OFF or in Intermittent mode, and operates the Wipers in a Low Speed continuous cycling mode while the Wash button is held on. After the Wash button is released, 2 additional complete cycles are performed at Low Speed. The Wiper system returns to the previous mode of operation following the completion of the additional Wipe cycles. Self Calibration A self calibration feature is used to eliminate performance variations due to tolerances in the resistances of the intermittent wiper switch. Following a power on reset, a default value is copied to a battery backed RAM memory location. If a valid resistance value greater than the current battery backed compensation value is measured during intermittent wiper operation, and it is present for 8 consecutive samples, the compensation value is replaced by the average of the compensation value and the new resistance value. This compensation value is used to calculate the intermittent wiper delay, using the following formula: Delay in seconds = 0.5 + 17.5* (resistance value/ compensation value) Three EEPROM locations have been provided to allow for optional calibration of the intermittent wipers. One location specifies a constant which will override the battery backed compensation value. The other locations specify constants which will override the default offset and slope used in converting resistance to time delay. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 1781 Failed Wiper Park Switch A failed Wiper Park Switch is determined by the CTM "C1" PIN # 11 input remaining high for eight seconds when the wiper system is in intermittent mode. Once detected, a code flag will be set in the EEPROM fault record byte. Once the Failed Wiper Park Switch fault is set, the intermittent wiper function will not operate until a low is seen on the CTM "C1" PIN # 11 input with the ignition ON. The code flag may only be cleared manually using a DRB. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Body Control Module > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures Body Control Module: Symptom Related Diagnostic Procedures Chime Inoperative at All Times SYMPTOM * CHIME INOPERATIVE AT ALL TIMES POSSIBLE CAUSES - Chime inoperative at all times Chime Inoperative With Any Warning Lamp on SYMPTOM * CHIME INOPERATIVE WITH ANY WARNING LAMP ON POSSIBLE CAUSES - Tone request signal circuit open - Instrument cluster defective - Central Timer Module defective Chime Inoperative With Exterior Lamps On SYMPTOM * CHIME INOPERATIVE WITH EXTERIOR LAMPS POSSIBLE CAUSES - Driver door ajar switch status no change - Left door ajar switch circuit open Chime Inoperative With Key In Ignition & Driver Door Open SYMPTOM * CHIME INOPERATIVE WITH KEY IN IGNITION, DRIVER'S DOOR OPEN POSSIBLE CAUSES - Driver door switch status not changing - Key in ignition switch sense circuit open - Defective Central Timer Module - Ignition switch defective Chime Inoperative With Only One Warning Lamp SYMPTOM * CHIME INOPERATIVE WITH ONLY ONE WARNING LAMP POSSIBLE CAUSES - Oil pressure sensor defective - Oil pressure sense circuit open - Powertrain Control Module defective - Cooling system operation faulty - DRB not showing PCM active on Bus - DRB shows ECT sensor voltage too high - DRB shows ECT sensor voltage too low Chime Remains on With the Ignition on SYMPTOM * CHIME REMAINS ON WITH THE IGNITION ON POSSIBLE CAUSES - Chime staying ON with ignition ON - Tone request signal circuit short - Central Timer Module defective - Instrument cluster defective Chime Sounds With Driver's Door Open SYMPTOM * CHIME SOUNDS WITH DRIVER'S DOOR OPEN POSSIBLE CAUSES Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Body Control Module > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures > Page 1784 - Chime sounds with key removed - Key in ignition switch sense circuit short - Left front door ajar switch sense circuit short - Driver door misaligned - Central Timer Module defective Courtesy Lamp Inoperative With Left Front Door SYMPTOM * COURTESY LAMPS INOPERATIVE FROM LEFT FRONT DOOR TEST NOTE This symptom is diagnosed using the test * OPEN DRIVER DOOR AJAR.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1804 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1805 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1806 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1807 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1808 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1809 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1821 Powertrain Control Module: Connector Views Powertrain Control Module Connectors Powertrain Control Module C1 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1822 Powertrain Control Module C2 Powertrain Control Module C3 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Description and Operation > Engine Control Powertrain Control Module: Description and Operation Engine Control POWERTRAIN CONTROL MODULE Powertrain Control Module (PCM) The Powertrain Control Module (PCM) is located in the engine compartment.

The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Refer to Camshaft Position Sensor, Ignition System for more information. CAMSHAFT POSITION SENSOR The camshaft position sensor is located in the distributor on all engines. The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal 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. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Locations > Page 1872 Camshaft Position Sensor: Service and Repair CAMSHAFT POSITION SENSOR Camshaft Position Sensor The camshaft position sensor is located in the distributor.

The sensors produce voltages from 0 to 1 volt, depending upon the oxygen content of the exhaust gas in the exhaust manifold. When a large amount of oxygen is present (caused by a lean air/fuel mixture), the sensors produces a low voltage. When there is a lesser amount present (rich air/fuel mixture) it produces a higher voltage. By monitoring the oxygen content and converting it to electrical voltage, the sensors act as a rich-lean switch. The oxygen sensors are equipped with a heating element that keeps the sensors at proper operating temperature during all operating modes. Maintaining correct sensor temperature at all times allows the system to enter into closed loop operation sooner. Also, it allows the system to remain in closed loop operation during periods of extended idle. In closed Loop operation, the PCM monitors the O2S sensor input (along with other inputs) and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values and inputs from other sensors. The Automatic Shutdown (ASD) relay supplies battery voltage to both the upstream and downstream heated oxygen sensors. The oxygen sensors are equipped with a heating element The heating elements reduce the time required for the sensors to reach operating temperature. UPSTREAM HEATED OXYGEN SENSOR Heated Oxygen Sensors The upstream O2S sensor is located in the inlet end of the catalytic converter. It provides an input voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The PCM uses this information to fine tune the air/fuel ratio by adjusting injector pulse width. DOWNSTREAM HEATED OXYGEN SENSOR The downstream heated oxygen sensor threads into the outlet end of the catalytic convertor. The downstream heated oxygen sensor input is used to detect catalytic convertor deterioration. As the convertor deteriorates, the input from the downstream sensor begins to match the upstream sensor input except for a slight time delay. By comparing the downstream heated oxygen sensor input to the input from the upstream sensor, the PCM calculates catalytic convertor efficiency. When the catalytic converter efficiency drops below emission standards, the PCM stores a diagnostic trouble code and illuminates the Malfunction Indicator Lamp (MIL). For more information., refer to Emission Control Systems. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Locations > Page 1928 Oxygen Sensor: Testing and Inspection To perform a complete test of the O2S sensors and their circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures.

The TPS is a variable resistor that provides the powertrain control module (PCM) with an input signal (voltage) that represents throttle blade position. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Specifications > Page 1936 Throttle Position Sensor: Testing and Inspection To perform a complete test of the TPS and its circuitry; refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures. To test the TPS only, refer to the following: The TPS can be tested with a digital voltmeter. The center terminal of the TPS is the output terminal. With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT). At idle, TPS output voltage should must be greater than 0.26 volts and less than 0.95 volts. At wide open throttle, TPS output voltage must be less than 4.49 volts. The output voltage should increase gradually as the throttle plate is slowly opened from idle to WOT. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Specifications > Page 1937 Throttle Position Sensor: Service and Repair THROTTLE POSITION SENSOR (TPS) MAP Sensor, TP Sensor, IAC Motor The TPS is located on the side of the throttle body.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1950 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1951 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1952 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1953 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1954 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated 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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1965 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1966 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1967 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Page 1968 Vehicle Speed Sensor: Description and Operation VEHICLE SPEED AND DISTANCE - PCM INPUT Vehicle speed and distance covered are measured by the Rear Wheel Speed Sensor. The sensor is mounted to the rear axle. A signal is sent from this sensor to the Controller Antilock Brake (CAB) computer. A signal is then sent from the CAB to the Powertrain Control Module (PCM) to determine vehicle speed and distance covered.

The TPS is a variable resistor that provides the powertrain control module (PCM) with an input signal (voltage) that represents throttle blade position. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Specifications > Page 1979 Throttle Position Sensor: Testing and Inspection To perform a complete test of the TPS and its circuitry; refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures. To test the TPS only, refer to the following: The TPS can be tested with a digital voltmeter. The center terminal of the TPS is the output terminal. With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT). At idle, TPS output voltage should must be greater than 0.26 volts and less than 0.95 volts. At wide open throttle, TPS output voltage must be less than 4.49 volts. The output voltage should increase gradually as the throttle plate is slowly opened from idle to WOT. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Specifications > Page 1980 Throttle Position Sensor: Service and Repair THROTTLE POSITION SENSOR (TPS) MAP Sensor, TP Sensor, IAC Motor The TPS is located on the side of the throttle body.

The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Refer to Camshaft Position Sensor, Ignition System for more information. CAMSHAFT POSITION SENSOR The camshaft position sensor is located in the distributor on all engines. The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal 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. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Locations > Page 1988 Camshaft Position Sensor: Service and Repair CAMSHAFT POSITION SENSOR Camshaft Position Sensor The camshaft position sensor is located in the distributor.

BEFORE DISCONNECTING FUEL LINE AT FUEL RAIL, THIS PRESSURE MUST BE RELEASED. REFER TO THE FUEL SYSTEM PRESSURE RELEASE PROCEDURE . Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Page 2011 Fuel Pressure: Testing and Inspection FUEL PRESSURE LEAK DOWN TEST Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity Test. Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1-2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by: - Fuel pressure bleeding past a fuel injector(s). - Fuel pressure bleeding past the check valve in the fuel pump module. 1. Disconnect the fuel inlet line at fuel rail. Refer to Fuel Tubes/Lines/Hoses and Clamps for procedures. On some engines, air cleaner housing removal may be necessary before fuel line disconnection. 2. Obtain correct Fuel Line Pressure Test Adapter Tool Hose. Tool number 6539 is used for 5/16" fuel lines and tool number 6631 is used for 3/8" fuel lines. Connecting Adapter Tool-Typical 3. Connect correct Fuel Line Pressure Test Adapter Tool Hose between disconnected fuel line and fuel rail. 4. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test port on the appropriate Adaptor Tool. The fittings on both tools must be in good condition and free from any small leaks before performing the proceeding test. 5. Start engine and bring to normal operating temperature. 6. Observe test gauge. Normal operating pressure should be 339 kPa + 34 kPa (49.2 psi + 5 psi). 7. Shut engine off. 8. Pressure should not fall below 30 psi for five minutes. 9. If pressure falls below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is leaking. 10. Again, start engine and bring to normal operating temperature. 11. Shut engine off. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Page 2012 12. Testing for fuel injector or fuel rail leakage: Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking. 13. Testing for fuel pump cheek valve, filter/regulator check valve or fuel tube/line leakage: Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line. If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump or filter/regulator may be leaking. NOTE: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A slow loss of pressure usually indicates a defective check valve in the electric fuel pump. The electric fuel pump is not serviced separately. Replace the fuel pump module assembly. The filter/ regulator may be replaced separately on certain applications.

These 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 2061 Ignition Cable: Testing and Inspection IGNITION CABLES Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and spark plugs. Terminals should be fully seated. The insulators should be in good condition and should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are cracked or torn must be replaced. Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the cables dry. Check for brittle or cracked insulation. Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable boot and spark plug. These shields protect the spark plug boots from damage (due to intense engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat shield. Testing When testing secondary cables for damage with an oscilloscope, follow the instructions of the equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as follows: CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during testing. This may cause possible heat damage to the catalytic converter. Total test time must not exceed ten minutes. With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to a good engine ground. If the cable and spark plug are in good condition, the engine rpm should drop and the engine will run poorly. If engine rpm does not drop, the cable and/or spark plug may not be operating properly and should be replaced. check engine cylinder compression. With the engine not running, connect one end of a test probe to a good ground. Start the engine and run the other end of the test probe along the entire length of all spark plug cables. If cables are cracked or punctured, there will be a noticeable spark jump from the damaged area to the test probe. The cable running from the ignition coil to the distributor cap can be checked in the same manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket. Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped, remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable. Test all spark plug cables in this manner. SPARK PLUG CABLE RESISTANCE Minimum Maximum 250 Ohms Per Inch 1000 Ohms Per Inch 3000 Ohms Per Foot 12,000 Ohms Per Foot To test ignition coil-to-distributor cap cable, do not remove the cable from the cap. Connect ohmmeter to rotor button (center contact) of distributor cap and terminal at ignition coil end of cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, remove the cable from the distributor cap. Connect the ohmmeter to the terminal ends of the cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, replace the cable. Inspect the ignition coil tower for cracks, burns or corrosion. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 2062 Ignition Cable: Service and Repair REMOVAL AND INSTALLATION Cable Removal CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap, twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off with a steady, even force. Engine Firing Order Install cables into the proper engine cylinder firing order. When replacing the spark plug and coil cables, route the cables correctly and secure in the proper retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could also cause cross ignition of the plugs or 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 between the plug cable and the distributor cap tower. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Distributor, Ignition > Distributor Cap > Component Information > Testing and Inspection Distributor Cap: Testing and Inspection Cap Inspection-External-Typical Cap Inspection-Internal-Typical Remove the distributor cap and wipe it clean with a dry lint free cloth. Visually inspect the cap for cracks, carbon paths, broken towers or damaged rotor button. Also check for white deposits on the inside (caused by condensation entering the cap through cracks). Replace any cap that displays charred or eroded terminals. The machined surface of a terminal end (faces toward rotor) will indicate some evidence of erosion from normal operation. Examine the terminal ends for evidence of mechanical interference with the rotor tip. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Distributor, Ignition > Ignition Rotor > Component Information > Testing and Inspection Ignition Rotor: Testing and Inspection Rotor Inspection-Typical Visually inspect the rotor for cracks, evidence of corrosion or the effects of arcing on the metal tip. Also check for evidence of mechanical interference with the cap. Some charring is normal on the end of the metal tip. The silicone-dielectric-varnish-compound applied to the rotor tip for radio interference noise suppression, will appear charred. This is normal. Do not remove the charred compound. Test the spring for insufficient tension. Replace a rotor that displays any of these adverse conditions. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications Spark Plug: Specifications Torque 30 ft.lb Electrode Gap 0.040 in Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2073 Spark Plug: Application and ID Plug Type ............................................................................................................................................ ....................................................................

Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in which they were removed from the engine. A single plug displaying an abnormal condition indicates that a problem exists in the corresponding cylinder. Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or oil fouled. Refer to the Spark Plug Condition. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2075 Spark Plug: Testing and Inspection SPARK PLUG CONDITIONS Normal Operation and Cold (Carbon) Fouling Normal Operating The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is evident with most grades of commercial gasoline. There will not be evidence of electrode burning. Gap growth will not average more than approximately 0.025 mm (0.001 in) per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the electrodes filed, have the gap set and then be installed. Some fuel refiners in several areas of the United States have introduced a manganese additive (MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits. Normal Operation and Cold (Carbon) Fouling Cold Fouling/Carbon Fouling Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be caused by a clogged air cleaner element or repeated short operating times (short trips). Wet Fouling or Gas Fouling A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the fouled plugs. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2076 Oil or Ash Encrusted Oil or Ash Encrusted If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of oil entry into that particular combustion chamber. Electrode Gap Bridging Electrode Gap Bridging Electrode gap bridging may be traced to loose deposits in the combustion chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be cleaned using standard procedures. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2077 Scavenger Deposits Scavenger Deposits Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is a normal condition caused by chemical additives in certain fuels. These additives are designed to change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in condition and can be cleaned using standard procedures. Chipped Electrode Insulator Chipped Electrode Insulator A chipped electrode insulator usually results from bending the center electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation can also separate the insulator from the center electrode. Spark plugs with this condition must be replaced. Preignition Damage Pre-ignition Damage Preignition damage is usually caused by excessive combustion chamber temperature. The center electrode dissolves first and the ground electrode Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2078 dissolves somewhat latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine. Determine if ignition timing is over advanced or if other operating conditions are causing engine overheating. (The heat range rating refers to the operating temperature of a particular type spark plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon the thickness and length of the center electrodes porcelain insulator.) Spark Plug Overheating Spark Plug Overheating Overheating is indicated by a white or gray center electrode insulator that also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug overheating. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2079 Spark Plug: Service and Repair Heat Shields Spark plug cable beat shields are pressed into the cylinder head to surround each cable boot and spark plug. If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides of shield for removal. Each shield is slotted to allow for compression and removal. To install the shields, align shield to machined opening in cylinder head and tap into place with a block of wood. PLUG REMOVAL 1. Remove engine cover. Cable Removal 2. Always remove spark plug or ignition coil cables by grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady motion. Never pull directly on the cable. Internal damage to cable will result. 3. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area around the spark plug. This will help prevent foreign material from entering the combustion chamber. 4. Remove the spark plug using a quality socket with a rubber or foam insert. 5. Inspect the spark plug condition. Refer to Spark Plug Condition. PLUG CLEANING The plugs may be cleaned using commercially available spark plug cleaning equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before adjusting gap. CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will remain on the spark plug insulator and will cause plug misfire. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2080 PLUG GAP ADJUSTMENT Setting Spark Plug Gap-Typical Check the spark plug gap with a gap gauge tool. If the gap is not correct, adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center electrode. SPARK PLUG GAP 1.01 mm (0.040 in). PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged. Always tighten spark plugs to the specified torque.. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator. When replacing the spark plug and ignition coil cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground. 1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark plugs to 35-41 Nm (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications Compression Check: Specifications Compression should not be less than 689 kPa (100 psi) and not vary more than 172 kPa (25 psi) from cylinder to cylinder. If cylinder(s) have abnormally low compression pressures, repeat procedure. - If the same cylinder(s) repeat an abnormally low reading, it could indicate the existence of a problem in the cylinder. NOTE: The recommended compression pressures are to be used only as a guide to diagnosing engine problems. An engine should NOT be disassembled to determine the cause of low compression unless some malfunction is present. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications > Page 2084 Compression Check: Testing and Inspection CYLINDER COMPRESSION PRESSURE TEST The results of a cylinder compression pressure test can be utilized to diagnose several engine malfunctions. Ensure the battery is completely charged and the engine starter motor is in good operating condition. Otherwise the indicated compression pressures may not be valid for diagnosis purposes. 1. Clean the spark plug recesses with compressed air. 2. Remove the spark plugs. 3. Secure the throttle in the wide-open position. 4. Disconnect the ignition coil. 5. Insert a compression pressure gauge and rotate the engine with the engine starter motor for three revolutions. 6. Record the compression pressure on the 3rd revolution. Continue the test for the remaining cylinders. Minimum cylinder compression pressure is 689 kPa (100 psi). Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Valve Clearance > System Information > Specifications Valve Clearance: Specifications These engines are equipped with hydraulic lash adjusters designed to maintain zero lash at all times. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > A/C Signal > Component Information > Description and Operation A/C Signal: Description and Operation AIR CONDITIONING (A/C) CONTROLS - PCM INPUT The A/C control system information applies to factory installed air conditioning units. A/C Select Signal When the A/C switch is in the ON position, an input signal is sent to the Powertrain Control Module (PCM). The signal informs the PCM that the A/C has been selected. The PCM adjusts idle speed to a pre-programmed rpm through the idle air control (IAC) motor to compensate for increased engine load. A/C Request Signal Once A/C has been selected, the PCM receives the A/C request signal from the clutch cycling pressure switch. The input indicates that the evaporator pressure is in the proper range for A/C application. The PCM uses this input to cycle the A/C compressor clutch (through the A/C relay). It will also determine the correct engine idle speed through the idle air control (IAC) motor position. If the A/C low-pressure switch or high-pressure switch opens (indicating a low or high refrigerant pressure), the PCM will not receive an A/C request signal. The PCM will then remove the ground from the A/C relay. This will deactivate the A/C compressor clutch. If the switch opens, (indicating that evaporator is not in proper pressure range), the PCM will not receive the A/C request signal. The PCM will then remove the ground from the A/C relay, deactivating the A/C compressor clutch. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Intake Air Temperature Sensor > Component Information > Specifications Intake Air Temperature Sensor: Specifications Intake Manifold Air Temp.

Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System Body Control Module: Description and Operation Airbag System Airbag System Description AIRBAG SYSTEM The Airbag Control Module (ACM) is secured to a bracket on the floor panel below the drivers seat. The ACM contains a microprocessor, the impact sensor, and energy storage capacitor. The microprocessor contains the airbag system logic. The ACM system logic includes On-Board Diagnostics (OBD) capability, and communicates with the instrument cluster circuitry on the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor in the ACM monitors the impact sensor signal and the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster on the CCD data bus to turn on the airbag indicator lamp. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbag system components. Only one impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags, for one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. The airbag warning lamp is the only point at which the customer can observe "symptoms" of a system malfunction, Whenever the ignition key is turned to the RUN or START position, the MIC performs a lamp check by turning the AIRBAG warning lamp ON for 6-8 seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the system or the MIC lamp circuit may be internally shorted to ground. If the lamp comes ON and stays ON for a period longer than 6-8 seconds then goes OFF, there is usually an intermittent problem in the system. The MIC monitors the airbag warning lamp and seat belt warning lamp during the bulb check for a defective bulb or lamp driver circuit. The MIC tests the airbag lamp during the cluster bulb check and substitutes the seat belt lamp if the airbag lamp is defective. If the airbag lamp is defective the MIC will turn the seat belt light ON and OFF approximately 30 times to warn the driver that the airbag lamp is defective. The lamp status is sent to the ACM continuously via a CCD bus message. The seat belt lamp acts as a backup in the event that the AIRBAG lamp is defective. This information is sent to the ACM continuously via a CCD bus message. Perform the WARNING LAMP BULB OR DRIVER procedure in this book to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated with no active DTC's The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. Service and general information labels about the airbag system can be found on the driver's sun visor, the glove box door, and in the engine compartment. WARNING: FAILURE TO HAVE THE AIRBAG SYSTEM PROPERLY SERVICED BY AN AUTHORIZED DEALER MAY LEAD TO POSSIBLE INJURY IN THE EVENT OF AN ACCIDENT.

The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator includes a small canister of highly compressed argon gas. The inflator seals the hold in the airbag cushion so it can discharge the compressed gas it contains directly into the cushion when supplied with the proper electrical signal. The airbag door has a living hinge at the top, which is secured to the instrument panel top cover. The door also has predetermined breakout lines concealed beneath its decorative cover. Upon airbag deployment the airbag door will split at the breakout lines and the door will pivot out of the way. The airbag module is secured at the bottom to the steel structural base of the instrument panel above the glove box opening. The airbag door is serviced as a unit with the passenger side airbag module, and includes the two passenger heating and air conditioning panel outlet housings. Following an airbag deployment, the airbag module and the instrument panel assembly must be replaced. Passenger Airbag On/Off Switch PASSENGER AIRBAG ON/OFF SWITCH The passenger side airbag ON/OFF switch is located on the instrument panel. To de-activate the passenger side airbag, turn the key actuator switch from the horizontal position to a slanted position (pointing to the "OFF" light indicator), approximately 45 degrees clockwise from the "ON" position. Rotating the key actuator switch 45 degrees clockwise, remove the key completely from the switch and verify that the switch actuator hole stays in the new position (45 degrees clockwise from horizontal). The switch is spring loaded to the "ON" position. It will return to the "ON" position unless you remove the key. When the IGNITION in ON, this procedure will illuminate the "OFF" light indicator on the passenger airbag ON/OFF switch.

The High Line utilizes a Central Timer Module (CTM) to provide the body features listed below. The CTM was designed to reduce cost, wiring complexity, and improve the system reliable. The CTM interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of information between modules and diagnostic capability using the DRB III. The CTM equipped vehicles can be identified by the sound of a Key-In Ignition CHIME. The Base AB RAM VAN body system is composed of individual modules. Because the stand-alone modules do not communicate on the CCD Bus, they cannot be diagnosed using the DRB. For concerns about the BASE AB VAN, refer to the appropriate service procedures. The Base version can be identified by the sound of the Key-In Ignition BUZZER. The CTM provides the following features: CCD Bus Communication - Chime - Courtesy Lamp Controls/Illuminated Entry - Enhanced Accident Response - Intermittent Wiper Delay - Power Door Locks W/RKE - Remote Keyless Entry (RKE) - Speed Sensitive Intermittent Wipers - Vehicle Theft Security System (VTSS) The module is located on the left center instrument panel support.

The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for gauge problems and tell tale warnings. The CTM chime functions will have priority over the MIC chime requests. There are two chime rates, Low; 50 chimes per minute for reminders and High; 180 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the driver door is open or the headlights are left ON. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for the key-in, and headlamp warning, as long as the drivers door is open. The seat belt warning chime is activated for 4 to 6 seconds , and all other chime conditions will activate the chime once at the same time the warning light ON the cluster is illuminated. The chime will sound for the following conditions: High rate Key in Warning ignition off, key in ignition, driver's door open - Ignition off, headlamps ON, driver's door open Low rate Seat belt warning - 6 seconds after key on (6 to 8 chimes) or until seatbelt is buckled - Airbag lamp illuminated (3 times after prove-out) - ABS lamp illuminated (2 chimes after prove-out if equipped) - Check engine lamp illuminated (2 chimes after prove-out) - Check gauges lamp illuminated (2 chimes) - Engine Temp High - when gauge enters red zone (2 chimes) - Low fuel - when fuel level reaches 1/8 tank (2 chimes) - Low washer fluid (2 chimes) - Transmission Temperature High (2 chimes) If the ignition switch is turned to the RUN/START position and the driver's door is closed, then opened, the warning chime is defeated. This allows the doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the OFF position, then normal function will be restored. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2120 Body Control Module: Description and Operation Airbag System Description AIRBAG SYSTEM The Airbag Control Module (ACM) is secured to a bracket on the floor panel below the drivers seat. The ACM contains a microprocessor, the impact sensor, and energy storage capacitor. The microprocessor contains the airbag system logic. The ACM system logic includes On-Board Diagnostics (OBD) capability, and communicates with the instrument cluster circuitry on the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor in the ACM monitors the impact sensor signal and the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster on the CCD data bus to turn on the airbag indicator lamp. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbag system components. Only one impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags, for one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. The airbag warning lamp is the only point at which the customer can observe "symptoms" of a system malfunction, Whenever the ignition key is turned to the RUN or START position, the MIC performs a lamp check by turning the AIRBAG warning lamp ON for 6-8 seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the system or the MIC lamp circuit may be internally shorted to ground. If the lamp comes ON and stays ON for a period longer than 6-8 seconds then goes OFF, there is usually an intermittent problem in the system. The MIC monitors the airbag warning lamp and seat belt warning lamp during the bulb check for a defective bulb or lamp driver circuit. The MIC tests the airbag lamp during the cluster bulb check and substitutes the seat belt lamp if the airbag lamp is defective. If the airbag lamp is defective the MIC will turn the seat belt light ON and OFF approximately 30 times to warn the driver that the airbag lamp is defective. The lamp status is sent to the ACM continuously via a CCD bus message. The seat belt lamp acts as a backup in the event that the AIRBAG lamp is defective. This information is sent to the ACM continuously via a CCD bus message. Perform the WARNING LAMP BULB OR DRIVER procedure in this book to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated with no active DTC's The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. Service and general information labels about the airbag system can be found on the driver's sun visor, the glove box door, and in the engine compartment. WARNING: FAILURE TO HAVE THE AIRBAG SYSTEM PROPERLY SERVICED BY AN AUTHORIZED DEALER MAY LEAD TO POSSIBLE INJURY IN THE EVENT OF AN ACCIDENT. Driver Airbag Module (DAB) DRIVER AIRBAG MODULE (DAB) The airbag protection trim cover is the most visible part of the driver side airbag system. The module is mounted directly to the steering wheel. Located under the trim cover are the horn switch, the airbag cushion, and the airbag cushion supporting components. The airbag module includes a Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2121 housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator seals the hole in the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. The protective trim cover is fitted to the front of the airbag module and forms a decorative cover in the center of the steering wheel. Upon airbag deployment, this cover will split at a predetermined breakout line. THE AIRBAG MODULE INFLATOR ASSEMBLY CONTAINS SODIUM AZIDE AND POTASSIUM NITRATE. THESE MATERIALS ARE POISONOUS AND EXTREMELY FLAMMABLE. CONTACT WITH ACID, WATER, OR HEAVY METALS MAY PRODUCE HARMFUL AND IRRITATING GASES (SODIUM HYDROXIDE IS FORMED IN THE PRESENCE OF MOISTURE) OR COMBUSTIBLE COMPOUNDS, IN ADDITION, THE PASSENGER AIRBAG MODULE CONTAINS ARGON GAS PRESSURIZED TO OVER 2500 PSI. DO NOT ATTEMPT TO DISMANTLE AN AIRBAG MODULE OR TAMPER WITH ITS INFLATOR. DO NOT PUNCTURE, INCINERATE, OR BRING INTO CONTACT WITH ELECTRICITY DO NOT STORE AT TEMPERATURE EXCEEDING 93°C (200°F). Clockspring CLOCKSPRING The clockspring is mounted on the steering column behind the steering wheel. This assembly consists of a plastic housing which contains a flat, ribbon-like, electrically conductive tape that winds and unwinds with the steering wheel rotation. The clockspring is used to maintain a continuous electrical circuit between the instrument panel wire harness and the driver side airbag module, the horn switch, and the vehicle speed control switches on vehicles that are so equipped. The clockspring must be properly centered when it is installed on the steering column following any service removal, or it will be damaged. The clockspring cannot be repaired it must be replaced. Passenger Airbag Module (PAB) PASSENGER AIRBAG MODULE (PAB) The airbag door in the instrument panel top cover above the glove box is the most visible part of the passenger side airbag system. Located under the airbag door is the airbag cushion and it's supporting components. The airbag module includes a housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator includes a small canister of highly compressed argon gas. The inflator seals the hold in the airbag cushion so it can discharge the compressed gas it contains directly into the cushion when supplied with the proper electrical signal. The airbag door has a living hinge at the top, which is secured to the instrument panel top cover. The door also has predetermined breakout lines concealed beneath its decorative cover. Upon airbag deployment the airbag door will split at the breakout lines and the door will pivot out of the way. The airbag module is secured at the bottom to the steel structural base of the instrument panel above the glove box opening. The airbag door is serviced as a unit with the passenger side airbag module, and includes the two passenger heating and air conditioning panel outlet housings. Following an airbag deployment, the airbag module and the instrument panel assembly must be replaced. Passenger Airbag On/Off Switch PASSENGER AIRBAG ON/OFF SWITCH The passenger side airbag ON/OFF switch is located on the instrument panel. To de-activate the passenger side airbag, turn the key actuator switch from the horizontal position to a slanted position (pointing to the "OFF" light indicator), approximately 45 degrees clockwise from the "ON" position. Rotating the key actuator switch 45 degrees clockwise, remove the key completely from the switch and verify that the switch actuator hole stays in the new position (45 degrees clockwise from horizontal). The switch is spring loaded to the "ON" position. It will return to the "ON" position unless you remove the key. When the IGNITION in ON, this procedure will illuminate the "OFF" light indicator on the passenger airbag ON/OFF switch. To re-enable the passenger side airbag, reverse the procedure above so that the key switch actuator is returned to a horizontal position. NOTE: DO NOT TURN IGNITION ON WITH KEY IN SWITCH. DO NOT TURN SWITCH WITH IGNITION ON. DO NOT LEAVE KEY IN SWITCH. THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG ON/OFF SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE ON/OFF KEY CYLINDER. The ON/OFF switch cannot be adjusted or repaired and, if faulty or damaged, the ON/OFF switch must be replaced.

This allows the doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the OFF position, then normal function will be restored. Description and Functional Operation DESCRIPTION AND FUNCTIONAL OPERATION The body system on the 1999 AB HIGH LINE consists of three modules that communicate over the CCD bus (Chrysler Collision Detection multiplex system). There are two additional modules, the Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are performed through the Serial Communication Interface of SCI, the same as previous years. All of the information about the functioning of all the system is organized, controlled, and communicated by (CCD Bus). Through the CCD bus, information about the operation of vehicle components and circuits is relayed quickly to the appropriate module(s). All modules receive all the information transmitted on the bus even though a module may not require all the information to perform it's function. It will only respond to messages "addressed" to it through a binary coding process. This method of data transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. DRB III Error Messages and Blank Screen DRB III ERROR MESSAGES AND BLANK SCREEN Under normal operation, the DRB will display one of only two error messages: User-Requested WARM Boot or - User-Requested COLD Boot If the DRB should display any other error message, record the entire display and call the MDS Hotline, or call for information and assistance at 1-800-825-8737. This is a sample of such an error message display: ver: 2.14 date: 26 Jul93 file: key_itf.cc date: Jul 26 1993 line: 548 err: Ox1 User-Requested COLD Boot Press MORE to switch between this display and the application screen. Press F4 when done noting information. DRB III Does Not Power Up (Blank Screen) If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (Data Link Connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, and inoperative DRB may be the result of a faulty cable or vehicle wiring. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2124 DRB III Scan Tool Display Is Not Visible Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition. Enhanced Accident Response (Highline CTM Only) ENHANCED ACCIDENT RESPONSE (Highline Only) If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The interior lights will be turned ON 10 seconds after getting zero speed message on the CCD bus. In addition to unlocking the doors, the lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "OFF" position, normal operation will resume. Diagnostics DIAGNOSTICS Gauges The instrument cluster will not store any DTC's. Because the engine controller PCM gathers all the gauge information and sends it to the cluster via the bus, it is the controller's responsibility to monitor these inputs and store DTC's for them. For this reason the first item to be checked regarding a gauge problem (except oil pressure) should be the engine controller for any DTC's relating to the gauge in question. There are DTC's associated with all the gauges except for the oil pressure gauge. When diagnosing gauges, the input that is used for gauge message (fuel level sender for example) must be valid. Because of OBD II requirements, most of the information used for monitoring the OBD II system happens to be the same information used by the controller to formulate the gauge bus messages. OBD II requirement state that the fuel level sender must be checked for rationality. This includes determining if the sending unit voltage is too high or too low or if the voltage hasn't changed over time. If the PCM has determined that the sender information isn't valid, it will send a diagnostic trouble code. The presence or absence of the fuel level sending code in the PCM is an important factor to determine whether a fuel gauge problem is in the sending unit or the cluster. The same situation is used in all cluster diagnostics related to gauge operation with the exception of the oil pressure gauge. OBD II requirements do not include oil pressure monitoring. Therefore, oil pressure diagnostic would dictate that a mechanical oil pressure gauge be attached to the engine for absolute verification of oil pressure readings. Hard Wired Lamps The cluster contains several hard wired lamps described earlier. The lamps are set up in two configurations. Either the cluster supplies power and ground is supplied by the circuit being monitored or the lamp is supplied ground by the cluster and power comes from a module or other device. Refer to the schematic for the specific details on the lamp in question. Verification of the bulb filament may be required in cases of an inoperative lamp. This will require removal of the cluster and bulb in question. NOTE: THE BRAKE, TRANS TEMP, CHECK GAUGES, SEAT BELTS AND AIRBAG WARNING LAMPS ARE LED'S, ALL OTHER ARE BULBS. IF ANY LED'S ARE DEFECTIVE,THE INSTRUMENT CLUSTER MUST BE REPLACED. CCD Controlled Lamps The cluster contains several CCD controlled lamps as described earlier. These lamps are part of the diagnostic self-test. When entering the self-test mode, operation of these lamps can be observed. If the bulb fails to operate during the self-test and the bulb filament is good, the cluster assembly will need to be replaced. NOTE: A FLASHING SEAT BELT LAMP INDICATES THAT THE AIRBAG WARNING LAMP IS NOT OPERATING PROPERLY. Mechanical Instrument Cluster Description MECHANICAL INSTRUMENT CLUSTER (MIC) Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2125 The Ram Van uses a standard MIC in all of it's U.S. vehicles. The cluster has 5 gauges and 15 indicator lamps. The gauges are positioned with information received over the CCD bus. Some of the indicator lamps are hardwired and the cluster using CCD bus information controls some. The MIC is hardwired to the CTM to provide the warning lamp announcement chimes. There is a self-test available for the cluster that will actuate all the gauges to their calibration points. The self test will not run if the cluster sees engine RPM or vehicle speed. The test will light all CCD controlled lamps for verification of lamp operation. It also forces the odometer Liquid Crystal Display (LCD) to perform a segment check. The self test routine can be entered by pressing and holding the trip reset button while rotating the ignition key from the OFF position to the ON position. When the word "check" appears, release the button and the test will continue. The cluster will provide bus bias termination and the engine controller provides a second termination. If the cluster is disconnected, the bus will not be biased. The cluster will be serviced as an assembly. There will be limited parts available, bulbs and sockets, the front lens, the trip odometer system cover and the rear cover assembly. No internal parts of the cluster will be serviceable. Normal Operation At key ON, the cluster will light the low fuel, seat belt, check gauges, and airbag. As the key is turned farther towards the start position, the check engine, ABS (if equipped) and brake warning lamp will illuminate. The liquid crystal display (LCD) will indicate the mileage stored inside the cluster. If there is a bus failure and the cluster cannot receive distance pulses from the engine controller, the cluster will display the last mileage stored until the ignition is turned OFF. If the cluster is receiving bus messages but is unable to display odometer information because of an internal failure, the odometer display will be blank. Dimming is handled by the potentiometer that controls instrumentation illumination. Lamps (Hardwired) The following lamps are hardwired in the cluster and are not part of the self-test. High Beam - Left Turn Signal - Right Turn Signal - Brake (comes ON during self-test) - Low Wash (comes during self-test) - Seat Belt (comes ON during self-test) Lamps (CCD) The cluster via CCD messages controls the following lamps. They are actuated during the self-test procedure. ABS lamps - Airbag - Check Engine - Check Gauges - Cruise Control Lamp - Security - Trans Temp - O/D OFF - Low Fuel Warning - Internally controlled by the cluster; not CCD NOTE: THE TURN SIGNALS, HIGH BEAM INDICATOR, SEAT BELT WARNING LAMP,LOW WASHER WARNING LAMP, AND BRAKE WARNING LAMP ARE HARDWIRED TO THE CLUSTER. Power Door Lock System POWER DOOR LOCKS The CTM controls the door lock actuation assemblies to handle locking and unlocking with the interior door lock switches or the RKE transmitter (key fob). There is also a door lock inhibit feature that prevents the power locking of the doors if the key is in the ignition or the headlamps are ON and the left front door is open. However, the doors can still be locked using the RKE transmitter which allows the engine to run for warm up purposes. Automatic (Rolling) Door Locks When the doors are closed and the vehicle speed exceeds 15 MPH due to engine power (not just rolling) and all doors are closed, the CTM will lock the doors. The vehicle is shipped with the automatic door lock feature disabled, but may be enabled using the DRB. Door Lock Delay If the CTM receives a signal to lock the doors and one or both of the auxiliary doors (side or rear) are open, the front doors will still lock. Five seconds after both of the auxiliary door are closed, the CTM will recycle the lock function. Remote Keyless Entry The CTM is compatible with a two button TRW RKE transmitter (keyfob). Two pre-programmed transmitters will be supplied with each vehicle. The CTM is capable of retaining up to four transmitters which can be programmed using the DRB. When a signal encoded with the correct vehicle access code is received and contains a valid message, the CTM will activate the corresponding relay to lock or unlock the doors. When an unlock Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2126 message is sent, all the doors will unlock, the VTSS will disarm and the illuminated entry will be activated. When a lock message is sent and all the doors are closed, all the doors will lock, the VTSS arming sequence will begin and the illuminated entry will turn OFF. Horn chirp When the doors are locked using the transmitter, a horn chirp will sound to let the customer know the doors were locked. The vehicle will be shipped with this function disabled but may be enabled using the DRB. The duration of the horn chirp can also be changed using the DRB. Trouble Codes AIRBAG DIAGNOSTIC TROUBLE CODES Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists, diagnostic priority should be given to the active codes. Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the trouble codes. It is not necessary to perform all of the tests in this book to diagnose an individual code. Always begin by reading the diagnostic trouble codes using the DRB III. This will direct you to the specific test(s) that must be performed Active diagnostic trouble codes for the airbag system are not permanent and will change the moment the reason for the code is corrected. In certain test procedures within this , diagnostic trouble codes are used as a diagnostic tool. Active Codes The code becomes active as soon as the malfunction is detected or key-OFF, whichever occurs first. An active trouble code indicates an on-going malfunction. This means that the defect is currently there every time the airbag control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected. With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present. The seat belt lamp replaces the airbag lamp if the airbag lamp is defective. The seat belt lamp pulses ON and OFF 30 times if the airbag warning lamp is defective. Stored Codes Airbag codes are automatically stored in the ACM's memory as soon as the malfunction is detected. The exception is the "Loss of Ignition Run Only" code which is an active code only. A "stored" code indicates there was an active code present sometime. However, the code currently may not be present as an active code, although another active code could be. When a trouble code occurs, the airbag warning lamp illuminates for 12 seconds minimum (even if the problem existed for less than 12 seconds). The code is stored, along with the time in minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. The minimum time shown for any code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two minutes 13 seconds, for example, would be three minutes. If malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored code. If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the problem. In this case, the stored code can indicate an area to inspect. If no obvious problems are found, erase stored codes, and with the ignition "ON" wiggle the wire harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes periodically as you work through the system. This procedure may uncover a malfunction that is difficult to locate. Airbag Trouble Codes The Airbag Control Module may report any of the following diagnostic trouble codes. For the following codes, replace the Airbag Control Module (ACM) even if set intermittently: ACM ACCELEROMETER - ACM OUTPUT DRIVER CIRCUIT OPEN - ACM INTERNAL DIAGNOSTIC CODE # 1 - ACM INTERNAL DIAGNOSTIC CODE # 2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2127 - ACM STORED ENERGY - ACM OUTPUT DRIVER For these codes, refer to the appropriate diagnostic procedure: Cluster Message Mismatch Driver Squib Circuit Open Driver Squib Circuit Shorted Driver Squib Circuit Shorted to Battery Driver Squib Circuit Shorted to Ground Loss of Ignition Run Only Loss of Ignition Run/Start NO Cluster CCD Message No CCD Communication Passenger Squib Circuit Open Passenger Squib Circuit Shorted Passenger Squib Circuit Shorted to Battery Passenger Squib Circuit Shorted to Ground Warning Lamp Open/Shorted Vehicle Communication VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the higher priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus -" (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a voltage divider network located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems use more than one. Some modules are capable of biasing and terminating the bus by themselves. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. Without termination, voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. In the 1999 Ram Van, the instrument cluster supplies bus bias and termination and the PCM supplies an additional point of termination. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLES ON-BOARD DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING.IF THERE IS A PROBLEM, REFER TO THE VEHICLE COMMUNICATION. Vehicle Theft Security System (VTSS) VEHICLE THEFT SECURITY SYSTEM (VTSS) The VTSS will monitor the states of the ignition, door lock signal, and all other doors to alert against unauthorized entry into the vehicle. The VTSS will be enabled at the assembly plant. To prevent arming of the VTSS during assembly and the shipping process, the vehicle must be started 20 times before the VTSS will operate properly. Arming the VTSS To arm the system, the ignition must be OFF and all doors must be closed and locked using either the power door lock switches or the RKE transmitter. Using a key or pressing the mechanical lock soldier will not initiate arming the VTSS. The delay lock feature will delay the arming process until all doors are closed. Once the VTSS begins to arm, the CTM will activate the security lamp output at a 1 Hz rate. During this process the arming process will terminate if the ignition is turned ON, if a door is opened, if the doors are unlocked using the door lock switch or the RKE transmitter, or if the front doors are unlocked using the key. After fifteen seconds of the arming process, the security lamp will go OFF and the VTSS will be armed. Once the vehicle is armed the ignition may be turned to the accessory position (to listen to radio, etc.) without triggering the alarm. The VTSS can only be disarmed using the key or the RKE transmitter. Triggering the VTSS Once the VTSS is armed, the alarm will trigger if any of the doors are opened or if the key is turned the Run/Start position. When triggered, the CTM will instruct the PCM to turn OFF the engine after two seconds and will pulse the horn and headlamps at a specified duty cycle and frequency. The audible (horn) warning will continue for three minutes then terminate. The visual (headlamps) warning will continue for fifteen additional minutes then terminate. The engine will continue to start and quit until the VTSS is disarmed. Tamper Alert If the VTSS was triggered during the last armed period, the next time it is disarmed the CTM will activate three horn chirps. To determine what caused the alarm to be tripped, using the DRB select "Theft Alarm" "Monitor Display" and observe: "Alarm Tripped by". This is a great tool to Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2128 use when a customer complains that the alarm went OFF and cannot determine what triggered it. Warnings WARNINGS Vehicle Damage Warnings Before disconnecting any control module, make sure the ignition is OFF. Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected. Road Testing A Complaint Vehicle Some complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic code or symptom condition. CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE REASSEMBLED DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB SCREEN WHILE IN MOTION.DO NOT HANG THE DRB FROM THE REAR VIEW MIRROR OR OPERATE IT YOURSELF.HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB. Wiper System WINDSHIELD WIPERS Feature Description The Ram Van equipped with a CTM will utilize speed sensitive intermittent wipe and wipe after wash function. The driver selects the Wiper function via a Steering Column mounted Stalk Switch. The Wiper system is operational whenever the ignition switch is in the Run or Accessory positions only (not during engine crank). The low and high speeds are controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as selected by the driver, and immediate wipe of the windshield takes place and the new delay interval is implemented. An Intermittent Wipe cycle consists of operating the Wipers in the Low Speed mode for one cycle, then executing a delay time. The delay time available to the driver is adjustable from 1/2 second to 18 seconds. Speed Sensitive Intermittent Wipe Operation Speed Intermittent Wipe is operational whenever the Ignition Switch is in either the RUN or ACCESSORY positions, and the voltage ON the CKT name input is greater than 4.5 VDC. The resistance selected by the stalk switch is used to set the delay time between wipe cycles. The Intermittent Wipe Delay Time is also adjusted based upon Vehicle Speed. When the Vehicle Speed is < 10 MPH then the driver selected Delay Time is doubled providing a range from 1 second to 36 seconds. When the vehicle speed is > 10 MPH then the driver selected Delay Time is not adjusted. An immediate Low Speed mode Wipe cycle will occur and a new Delay Time interval will start if the driver changes the current selected Delay Time to a shorter interval. The speed signal is provided to the CTM from the PCM over the CCD bus. Wipe after Wash Operation Wipe after Wash operation activates the Wiper system when the Wash button is pressed. Wiper after Wash operation is available while the wiper switch is OFF or in Intermittent mode, and operates the Wipers in a Low Speed continuous cycling mode while the Wash button is held on. After the Wash button is released, 2 additional complete cycles are performed at Low Speed. The Wiper system returns to the previous mode of operation following the completion of the additional Wipe cycles. Self Calibration A self calibration feature is used to eliminate performance variations due to tolerances in the resistances of the intermittent wiper switch. Following a power on reset, a default value is copied to a battery backed RAM memory location. If a valid resistance value greater than the current battery backed compensation value is measured during intermittent wiper operation, and it is present for 8 consecutive samples, the compensation value is replaced by the average of the compensation value and the new resistance value. This compensation value is used to calculate the intermittent wiper delay, using the following formula: Delay in seconds = 0.5 + 17.5* (resistance value/ compensation value) Three EEPROM locations have been provided to allow for optional calibration of the intermittent wipers. One location specifies a constant which will override the battery backed compensation value. The other locations specify constants which will override the default offset and slope used in converting resistance to time delay. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2129 Failed Wiper Park Switch A failed Wiper Park Switch is determined by the CTM "C1" PIN # 11 input remaining high for eight seconds when the wiper system is in intermittent mode. Once detected, a code flag will be set in the EEPROM fault record byte. Once the Failed Wiper Park Switch fault is set, the intermittent wiper function will not operate until a low is seen on the CTM "C1" PIN # 11 input with the ignition ON. The code flag may only be cleared manually using a DRB. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Body Control Module > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures Body Control Module: Symptom Related Diagnostic Procedures Chime Inoperative at All Times SYMPTOM * CHIME INOPERATIVE AT ALL TIMES POSSIBLE CAUSES - Chime inoperative at all times Chime Inoperative With Any Warning Lamp on SYMPTOM * CHIME INOPERATIVE WITH ANY WARNING LAMP ON POSSIBLE CAUSES - Tone request signal circuit open - Instrument cluster defective - Central Timer Module defective Chime Inoperative With Exterior Lamps On SYMPTOM * CHIME INOPERATIVE WITH EXTERIOR LAMPS POSSIBLE CAUSES - Driver door ajar switch status no change - Left door ajar switch circuit open Chime Inoperative With Key In Ignition & Driver Door Open SYMPTOM * CHIME INOPERATIVE WITH KEY IN IGNITION, DRIVER'S DOOR OPEN POSSIBLE CAUSES - Driver door switch status not changing - Key in ignition switch sense circuit open - Defective Central Timer Module - Ignition switch defective Chime Inoperative With Only One Warning Lamp SYMPTOM * CHIME INOPERATIVE WITH ONLY ONE WARNING LAMP POSSIBLE CAUSES - Oil pressure sensor defective - Oil pressure sense circuit open - Powertrain Control Module defective - Cooling system operation faulty - DRB not showing PCM active on Bus - DRB shows ECT sensor voltage too high - DRB shows ECT sensor voltage too low Chime Remains on With the Ignition on SYMPTOM * CHIME REMAINS ON WITH THE IGNITION ON POSSIBLE CAUSES - Chime staying ON with ignition ON - Tone request signal circuit short - Central Timer Module defective - Instrument cluster defective Chime Sounds With Driver's Door Open SYMPTOM * CHIME SOUNDS WITH DRIVER'S DOOR OPEN POSSIBLE CAUSES Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Body Control Module > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures > Page 2132 - Chime sounds with key removed - Key in ignition switch sense circuit short - Left front door ajar switch sense circuit short - Driver door misaligned - Central Timer Module defective Courtesy Lamp Inoperative With Left Front Door SYMPTOM * COURTESY LAMPS INOPERATIVE FROM LEFT FRONT DOOR TEST NOTE This symptom is diagnosed using the test * OPEN DRIVER DOOR AJAR.

The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Refer to Camshaft Position Sensor, Ignition System for more information. CAMSHAFT POSITION SENSOR The camshaft position sensor is located in the distributor on all engines. The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal 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. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Locations > Page 2150 Camshaft Position Sensor: Service and Repair CAMSHAFT POSITION SENSOR Camshaft Position Sensor The camshaft position sensor is located in the distributor.

The sensor provides an input voltage to the powertrain control module (PCM) relating coolant temperature. The PCM uses this input along with inputs from other sensors to determine injector pulse width and ignition timing. As coolant temperature varies, the coolant temperature sensor resistance will change. This change in resistance results in a different input voltage to the PCM. When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air-fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 2158 Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection COOLANT TEMPERATURE SENSOR To perform a complete test of the engine coolant temperature sensor and its circuitry, refer to DRB scan tool and appropriate Powertrain Diagnostics Procedures.

This sensor is used to indicate to the powertrain control module (PCM) that a spark and or fuel injection event is to be required. The output from this sensor, in conjunction with the camshaft position sensor signal, is used to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders. Crankshaft Position Sensor-Typical The sensor is bolted to the cylinder block near the rear of the right cylinder head. Refer to Ignition System for more crankshaft position sensor information. The engine will not operate if the PCM does not receive a crankshaft position sensor input. CRANKSHAFT POSITION SENSOR Engine speed and crankshaft position are provided through the 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Specifications > Page 2167 Sensor Operation On these engines, the flywheel/drive plate has 8 single notches, spaced every 45 degrees, 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. For each engine revolution, there are 8 pulses generated on V-8 engines. The engine will not operate if the PCM does not receive a crankshaft position sensor input. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Crankshaft Position Sensor > Component Information > Specifications > Page 2168 Crankshaft Position Sensor: Service and Repair CRANKSHAFT POSITION SENSOR REMOVAL Crankshaft Position Sensor-Typical The sensor is bolted to the top of the cylinder block near the rear of right cylinder head. 1.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2175 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2176 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2177 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2178 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2179 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2180 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2190 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2191 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2201 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2202 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2203 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2204 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING.

Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2217 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2218 Powertrain Control Module: Connector Views Powertrain Control Module Connectors Powertrain Control Module C1 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2219 Powertrain Control Module C2 Powertrain Control Module C3 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Description and Operation > Engine Control Powertrain Control Module: Description and Operation Engine Control POWERTRAIN CONTROL MODULE Powertrain Control Module (PCM) The Powertrain Control Module (PCM) is located in the engine compartment. The ignition system is controlled by the PCM. NOTE: Base ignition timing by rotation of distributor is not adjustable. The PCM opens and closes the ignition coil ground circuit to operate the ignition coil. This is done to adjust ignition timing, both initial (base) and advance, and for changing engine operating conditions. The amount of electronic spark advance provided by the PCM is determined by five input factors: engine coolant temperature, engine rpm, intake manifold temperature, manifold absolute pressure and throttle position. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Description and Operation > Engine Control > Page 2222 Powertrain Control Module: Description and Operation Transmission Control The Powertrain Control Module (PCM) controls operation of the converter clutch, overdrive clutch, and governor pressure solenoid.

The fuel level sensor will then return a signal to the PCM to indicate fuel level. The purpose of this feature is to prevent a false setting of misfire and fuel system monitor trouble codes. This is if the fuel level is less than approximately 15 percent, or, if equipped with a Leak Detection Pump (LDP), more than approximately 85 percent of its rated capacity. This input is also used to send a signal to the PCM for fuel gauge operation via the CCD or J1850 bus circuits. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Idle Speed/Throttle Actuator Electronic > Component Information > Specifications Idle Speed/Throttle Actuator - Electronic: Specifications IAC Motor-To-Throttle Body Bolts 7 Nm Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Idle Speed/Throttle Actuator Electronic > Component Information > Specifications > Page 2230 Idle Speed/Throttle Actuator - Electronic: Locations MAP Sensor, TP Sensor, IAC Motor The IAC motor is located on the back of the throttle body. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Idle Speed/Throttle Actuator Electronic > Component Information > Specifications > Page 2231 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Idle Speed/Throttle Actuator Electronic > Component Information > Specifications > Page 2232 Idle Speed/Throttle Actuator - Electronic: Description and Operation IDLE AIR CONTROL (IAC) MOTOR - PCM OUTPUT MAP and Throttle Position Sensor Location-Typical The IAC motor is mounted to the back of the throttle body and is controlled by the powertrain control module (PCM).

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2240 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2241 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2242 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2243 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2244 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2245 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2255 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2256 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2257 Vehicle Communications Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Page 2258 Information Bus: Description and Operation VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the higher priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus + " (bus plus) and "bus - " (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a voltage divider network located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems use more than one. Some modules are capable of biasing and terminating the bus by themselves. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. Without termination, voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. In the 1999 Ram Van, the instrument cluster supplies bus bias and termination and the PCM supplies an additional point of termination. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLES ON-BOARD DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING.IF THERE IS A PROBLEM, REFER TO THE VEHICLE COMMUNICATION. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Automatic Shut Down (ASD) Relay <--> [Main Relay (Computer/Fuel System)] > Component Information > Locations Automatic Shut Down (ASD) Relay: Locations Power Distribution Center (PDC) Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Automatic Shut Down (ASD) Relay <--> [Main Relay (Computer/Fuel System)] > Component Information > Locations > Page 2262 8w-10-2 The ASD relay is located in the Power Distribution Center (PDC). Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Automatic Shut Down (ASD) Relay <--> [Main Relay (Computer/Fuel System)] > Component Information > Locations > Page 2263 Automatic Shut Down (ASD) Relay: Diagrams Power Distribution Center Automatic Shut Down Relay Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Automatic Shut Down (ASD) Relay <--> [Main Relay (Computer/Fuel System)] > Component Information > Locations > Page 2264 Automatic Shut Down (ASD) Relay: Description and Operation AUTOMATIC SHUTDOWN (ASD) RELAY - PCM INPUT Power Distribution Center (PDC) Location A 12 volt signal at this input indicates to the PCM that the ASD has been activated. The ASD relay is located in the Power Distribution Center (PDC). The PDC is located in the engine compartment next to the battery. Refer to label on PDC cover for relay location. 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 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). The ASD relay is located in the Power Distribution Center (PDC). The ASD supplies battery voltage to the fuel injectors and ignition coil(s). With certain emissions packages it also supplies voltage to the oxygen sensor heating elements. The ground circuit for the coil in the ASD relay is controlled by the Powertrain Control Module (PCM). The PCM operates the relay by switching the ground circuit on and off. AUTO SHUTDOWN (ASD) RELAY - PCM OUTPUT The ASD relay is located in the Power Distribution Center (PDC). The ASD supplies battery voltage to the fuel injectors and ignition coil(s). With certain emissions packages it also supplies voltage to the oxygen sensor heating elements. The ground circuit for the coil in the ASD relay is controlled by the Powertrain Control Module (PCM). The PCM operates the relay by switching the ground circuit on and off. Refer to Instrument Panel and Gauges for additional information. AUTOMATIC SHUTDOWN (ASD) RELAY As one of its functions, the ASD relay will supply battery voltage to the ignition coil. The ground circuit for the ASD relay is controlled by the Powertrain Control Module (PCM). The PCM regulates ASD relay operation by switching the ground circuit on-and-off. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Automatic Shut Down (ASD) Relay <--> [Main Relay (Computer/Fuel System)] > Component Information > Locations > Page 2265 Automatic Shut Down (ASD) Relay: Testing and Inspection AUTOMATIC SHUT DOWN (ASD) RELAY The following operation/tests apply only to the Automatic Shutdown (ASD) and fuel pump relays .

It provides an input voltage to the powertrain control module (PCM). As engine load changes, manifold pressure varies. The change in manifold pressure causes MAP sensor voltage to change. The change in MAP sensor voltage results in a different input voltage to the PCM. The input voltage level supplies the PCM with information about ambient barometric pressure during engine start-up (cranking) and engine load while the engine is running. The PCM uses this input along with inputs from other sensors to adjust air-fuel mixture MAP and Throttle Position Sensor Location-Typical The MAP sensor is mounted on the side of the engine throttle body.

The sensors produce voltages from 0 to 1 volt, depending upon the oxygen content of the exhaust gas in the exhaust manifold. When a large amount of oxygen is present (caused by a lean air/fuel mixture), the sensors produces a low voltage. When there is a lesser amount present (rich air/fuel mixture) it produces a higher voltage. By monitoring the oxygen content and converting it to electrical voltage, the sensors act as a rich-lean switch. The oxygen sensors are equipped with a heating element that keeps the sensors at proper operating temperature during all operating modes. Maintaining correct sensor temperature at all times allows the system to enter into closed loop operation sooner. Also, it allows the system to remain in closed loop operation during periods of extended idle. In closed Loop operation, the PCM monitors the O2S sensor input (along with other inputs) and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values and inputs from other sensors. The Automatic Shutdown (ASD) relay supplies battery voltage to both the upstream and downstream heated oxygen sensors. The oxygen sensors are equipped with a heating element The heating elements reduce the time required for the sensors to reach operating temperature. UPSTREAM HEATED OXYGEN SENSOR Heated Oxygen Sensors The upstream O2S sensor is located in the inlet end of the catalytic converter. It provides an input voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The PCM uses this information to fine tune the air/fuel ratio by adjusting injector pulse width. DOWNSTREAM HEATED OXYGEN SENSOR The downstream heated oxygen sensor threads into the outlet end of the catalytic convertor. The downstream heated oxygen sensor input is used to detect catalytic convertor deterioration. As the convertor deteriorates, the input from the downstream sensor begins to match the upstream sensor input except for a slight time delay. By comparing the downstream heated oxygen sensor input to the input from the upstream sensor, the PCM calculates catalytic convertor efficiency. When the catalytic converter efficiency drops below emission standards, the PCM stores a diagnostic trouble code and illuminates the Malfunction Indicator Lamp (MIL). For more information., refer to Emission Control Systems. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Locations > Page 2297 Oxygen Sensor: Testing and Inspection To perform a complete test of the O2S sensors and their circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures. To test the O2S sensors only, refer to the following: Oxygen Sensor Location The upstream O2S sensor is located on the inlet end of the catalytic converter. The downstream O2S sensor is located on the outlet end of the catalytic converter. Each O2S heating element can be tested with an ohmmeter as follows: Disconnect the O2S sensor connector. Connect the ohmmeter test leads across the white wire terminals of the sensor connector. Resistance should be between 4.5 ± 0.5 ohms and 7 ohms. Replace the sensor if the ohmmeter displays an infinity (open) reading. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Locations > Page 2298 Oxygen Sensor: Service and Repair UPSTREAM OXYGEN SENSOR Oxygen Sensor Location The O2S sensors are located at the inlet and outlet ends of the catalytic converter.

Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System Body Control Module: Description and Operation Airbag System Airbag System Description AIRBAG SYSTEM The Airbag Control Module (ACM) is secured to a bracket on the floor panel below the drivers seat. The ACM contains a microprocessor, the impact sensor, and energy storage capacitor. The microprocessor contains the airbag system logic. The ACM system logic includes On-Board Diagnostics (OBD) capability, and communicates with the instrument cluster circuitry on the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor in the ACM monitors the impact sensor signal and the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster on the CCD data bus to turn on the airbag indicator lamp. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbag system components. Only one impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags, for one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. The airbag warning lamp is the only point at which the customer can observe "symptoms" of a system malfunction, Whenever the ignition key is turned to the RUN or START position, the MIC performs a lamp check by turning the AIRBAG warning lamp ON for 6-8 seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the system or the MIC lamp circuit may be internally shorted to ground. If the lamp comes ON and stays ON for a period longer than 6-8 seconds then goes OFF, there is usually an intermittent problem in the system. The MIC monitors the airbag warning lamp and seat belt warning lamp during the bulb check for a defective bulb or lamp driver circuit. The MIC tests the airbag lamp during the cluster bulb check and substitutes the seat belt lamp if the airbag lamp is defective. If the airbag lamp is defective the MIC will turn the seat belt light ON and OFF approximately 30 times to warn the driver that the airbag lamp is defective. The lamp status is sent to the ACM continuously via a CCD bus message. The seat belt lamp acts as a backup in the event that the AIRBAG lamp is defective. This information is sent to the ACM continuously via a CCD bus message. Perform the WARNING LAMP BULB OR DRIVER procedure in this book to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated with no active DTC's The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. Service and general information labels about the airbag system can be found on the driver's sun visor, the glove box door, and in the engine compartment. WARNING: FAILURE TO HAVE THE AIRBAG SYSTEM PROPERLY SERVICED BY AN AUTHORIZED DEALER MAY LEAD TO POSSIBLE INJURY IN THE EVENT OF AN ACCIDENT.

Clockspring CLOCKSPRING The clockspring is mounted on the steering column behind the steering wheel. This assembly consists of a plastic housing which contains a flat, ribbon-like, electrically conductive tape that winds and unwinds with the steering wheel rotation. The clockspring is used to maintain a continuous electrical circuit between the instrument panel wire harness and the driver side airbag module, the horn switch, and the vehicle speed control switches on vehicles that are so equipped. The clockspring must be properly centered when it is installed on the steering column following any service removal, or it will be damaged. The clockspring cannot be repaired it must be replaced. Passenger Airbag Module (PAB) PASSENGER AIRBAG MODULE (PAB) The airbag door in the instrument panel top cover above the glove box is the most visible part of the passenger side airbag system. Located under the airbag door is the airbag cushion and it's supporting components. The airbag module includes a housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator includes a small canister of highly compressed argon gas. The inflator seals the hold in the airbag cushion so it can discharge the compressed gas it contains directly into the cushion when supplied with the proper electrical signal. The airbag door has a living hinge at the top, which is secured to the instrument panel top cover. The door also has predetermined breakout lines concealed beneath its decorative cover. Upon airbag deployment the airbag door will split at the breakout lines and the door will pivot out of the way. The airbag module is secured at the bottom to the steel structural base of the instrument panel above the glove box opening. The airbag door is serviced as a unit with the passenger side airbag module, and includes the two passenger heating and air conditioning panel outlet housings. Following an airbag deployment, the airbag module and the instrument panel assembly must be replaced. Passenger Airbag On/Off Switch PASSENGER AIRBAG ON/OFF SWITCH The passenger side airbag ON/OFF switch is located on the instrument panel. To de-activate the passenger side airbag, turn the key actuator switch from the horizontal position to a slanted position (pointing to the "OFF" light indicator), approximately 45 degrees clockwise from the "ON" position. Rotating the key actuator switch 45 degrees clockwise, remove the key completely from the switch and verify that the switch actuator hole stays in the new position (45 degrees clockwise from horizontal). The switch is spring loaded to the "ON" position. It will return to the "ON" position unless you remove the key. When the IGNITION in ON, this procedure will illuminate the "OFF" light indicator on the passenger airbag ON/OFF switch. To re-enable the passenger side airbag, reverse the procedure above so that the key switch actuator is returned to a horizontal position. NOTE: DO NOT TURN IGNITION ON WITH KEY IN SWITCH. DO NOT TURN SWITCH WITH IGNITION ON. DO NOT LEAVE KEY IN SWITCH. THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG ON/OFF SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED.

While the vehicle is off the illuminated entry feature can be activated in the following ways. Whenever a door is opened - When the vehicle is unlocked with a key - When the CTM receives a valid unlock signal from the RKE transmitter The illuminated entry will remain ON for 30 seconds after the last door is closed, turn OFF immediately after ignition is turned ON, or turn OFF when the CTM receives a LOCK message from the RKE transmitter. 15 Minute Illumination Timeout If the ignition is OFF and either front door is open, interior illumination will terminate after 15 minutes. If either front door is open and the ignition is turned in the RUN or ACCESSORY position, interior illumination will continue until the ignition is turned OFF. Once the ignition is OFF, if either front door remains open, the 15 minute interior illumination timeout will begin. Note: This timeout feature does not apply to either auxiliary door or the dome lamp switch which are hardwired to the courtesy lamps. The auxiliary door switches are also wired to the CTM to operate illuminated entry. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2309 Body Control Module: Description and Operation Central Timer Module CENTRAL TIMER MODULE (CTM) The AB RAM VAN has two different body electrical systems, High Line and Base. The High Line utilizes a Central Timer Module (CTM) to provide the body features listed below. The CTM was designed to reduce cost, wiring complexity, and improve the system reliable. The CTM interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of information between modules and diagnostic capability using the DRB III. The CTM equipped vehicles can be identified by the sound of a Key-In Ignition CHIME. The Base AB RAM VAN body system is composed of individual modules. Because the stand-alone modules do not communicate on the CCD Bus, they cannot be diagnosed using the DRB. For concerns about the BASE AB VAN, refer to the appropriate service procedures. The Base version can be identified by the sound of the Key-In Ignition BUZZER. The CTM provides the following features: CCD Bus Communication - Chime - Courtesy Lamp Controls/Illuminated Entry - Enhanced Accident Response - Intermittent Wiper Delay - Power Door Locks W/RKE - Remote Keyless Entry (RKE) - Speed Sensitive Intermittent Wipers - Vehicle Theft Security System (VTSS) The module is located on the left center instrument panel support. It contains a white 18-way and a green 14-way connector.

The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for gauge problems and tell tale warnings. The CTM chime functions will have priority over the MIC chime requests. There are two chime rates, Low; 50 chimes per minute for reminders and High; 180 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the driver door is open or the headlights are left ON. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for the key-in, and headlamp warning, as long as the drivers door is open. The seat belt warning chime is activated for 4 to 6 seconds , and all other chime conditions will activate the chime once at the same time the warning light ON the cluster is illuminated. The chime will sound for the following conditions: High rate Key in Warning ignition off, key in ignition, driver's door open - Ignition off, headlamps ON, driver's door open Low rate Seat belt warning - 6 seconds after key on (6 to 8 chimes) or until seatbelt is buckled - Airbag lamp illuminated (3 times after prove-out) - ABS lamp illuminated (2 chimes after prove-out if equipped) - Check engine lamp illuminated (2 chimes after prove-out) - Check gauges lamp illuminated (2 chimes) - Engine Temp High - when gauge enters red zone (2 chimes) - Low fuel - when fuel level reaches 1/8 tank (2 chimes) - Low washer fluid (2 chimes) - Transmission Temperature High (2 chimes) If the ignition switch is turned to the RUN/START position and the driver's door is closed, then opened, the warning chime is defeated. This allows the doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the OFF position, then normal function will be restored. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2311 Body Control Module: Description and Operation Airbag System Description AIRBAG SYSTEM The Airbag Control Module (ACM) is secured to a bracket on the floor panel below the drivers seat.

The purpose of the capacitor is to provide airbag system protection in a severe secondary impact if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. The airbag warning lamp is the only point at which the customer can observe "symptoms" of a system malfunction, Whenever the ignition key is turned to the RUN or START position, the MIC performs a lamp check by turning the AIRBAG warning lamp ON for 6-8 seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the system or the MIC lamp circuit may be internally shorted to ground. If the lamp comes ON and stays ON for a period longer than 6-8 seconds then goes OFF, there is usually an intermittent problem in the system. The MIC monitors the airbag warning lamp and seat belt warning lamp during the bulb check for a defective bulb or lamp driver circuit. The MIC tests the airbag lamp during the cluster bulb check and substitutes the seat belt lamp if the airbag lamp is defective. If the airbag lamp is defective the MIC will turn the seat belt light ON and OFF approximately 30 times to warn the driver that the airbag lamp is defective. The lamp status is sent to the ACM continuously via a CCD bus message. The seat belt lamp acts as a backup in the event that the AIRBAG lamp is defective. This information is sent to the ACM continuously via a CCD bus message. Perform the WARNING LAMP BULB OR DRIVER procedure in this book to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated with no active DTC's The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. Service and general information labels about the airbag system can be found on the driver's sun visor, the glove box door, and in the engine compartment. WARNING: FAILURE TO HAVE THE AIRBAG SYSTEM PROPERLY SERVICED BY AN AUTHORIZED DEALER MAY LEAD TO POSSIBLE INJURY IN THE EVENT OF AN ACCIDENT. Driver Airbag Module (DAB) DRIVER AIRBAG MODULE (DAB) The airbag protection trim cover is the most visible part of the driver side airbag system. The module is mounted directly to the steering wheel. Located under the trim cover are the horn switch, the airbag cushion, and the airbag cushion supporting components. The airbag module includes a Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2312 housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator seals the hole in the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. The protective trim cover is fitted to the front of the airbag module and forms a decorative cover in the center of the steering wheel. Upon airbag deployment, this cover will split at a predetermined breakout line. THE AIRBAG MODULE INFLATOR ASSEMBLY CONTAINS SODIUM AZIDE AND POTASSIUM NITRATE. THESE MATERIALS ARE POISONOUS AND EXTREMELY FLAMMABLE. CONTACT WITH ACID, WATER, OR HEAVY METALS MAY PRODUCE HARMFUL AND IRRITATING GASES (SODIUM HYDROXIDE IS FORMED IN THE PRESENCE OF MOISTURE) OR COMBUSTIBLE COMPOUNDS, IN ADDITION, THE PASSENGER AIRBAG MODULE CONTAINS ARGON GAS PRESSURIZED TO OVER 2500 PSI. DO NOT ATTEMPT TO DISMANTLE AN AIRBAG MODULE OR TAMPER WITH ITS INFLATOR. DO NOT PUNCTURE, INCINERATE, OR BRING INTO CONTACT WITH ELECTRICITY DO NOT STORE AT TEMPERATURE EXCEEDING 93°C (200°F). Clockspring CLOCKSPRING The clockspring is mounted on the steering column behind the steering wheel. This assembly consists of a plastic housing which contains a flat, ribbon-like, electrically conductive tape that winds and unwinds with the steering wheel rotation. The clockspring is used to maintain a continuous electrical circuit between the instrument panel wire harness and the driver side airbag module, the horn switch, and the vehicle speed control switches on vehicles that are so equipped. The clockspring must be properly centered when it is installed on the steering column following any service removal, or it will be damaged. The clockspring cannot be repaired it must be replaced. Passenger Airbag Module (PAB) PASSENGER AIRBAG MODULE (PAB) The airbag door in the instrument panel top cover above the glove box is the most visible part of the passenger side airbag system. Located under the airbag door is the airbag cushion and it's supporting components. The airbag module includes a housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator includes a small canister of highly compressed argon gas. The inflator seals the hold in the airbag cushion so it can discharge the compressed gas it contains directly into the cushion when supplied with the proper electrical signal. The airbag door has a living hinge at the top, which is secured to the instrument panel top cover. The door also has predetermined breakout lines concealed beneath its decorative cover. Upon airbag deployment the airbag door will split at the breakout lines and the door will pivot out of the way. The airbag module is secured at the bottom to the steel structural base of the instrument panel above the glove box opening. The airbag door is serviced as a unit with the passenger side airbag module, and includes the two passenger heating and air conditioning panel outlet housings. Following an airbag deployment, the airbag module and the instrument panel assembly must be replaced. Passenger Airbag On/Off Switch PASSENGER AIRBAG ON/OFF SWITCH The passenger side airbag ON/OFF switch is located on the instrument panel. To de-activate the passenger side airbag, turn the key actuator switch from the horizontal position to a slanted position (pointing to the "OFF" light indicator), approximately 45 degrees clockwise from the "ON" position. Rotating the key actuator switch 45 degrees clockwise, remove the key completely from the switch and verify that the switch actuator hole stays in the new position (45 degrees clockwise from horizontal). The switch is spring loaded to the "ON" position. It will return to the "ON" position unless you remove the key. When the IGNITION in ON, this procedure will illuminate the "OFF" light indicator on the passenger airbag ON/OFF switch. To re-enable the passenger side airbag, reverse the procedure above so that the key switch actuator is returned to a horizontal position. NOTE: DO NOT TURN IGNITION ON WITH KEY IN SWITCH. DO NOT TURN SWITCH WITH IGNITION ON. DO NOT LEAVE KEY IN SWITCH. THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG ON/OFF SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE ON/OFF KEY CYLINDER. The ON/OFF switch cannot be adjusted or repaired and, if faulty or damaged, the ON/OFF switch must be replaced.

Interior Lighting INTERIOR LIGHTING The illuminated Entry system consist of a maximum of three dome lamps which are located in the front, middle and rear of the head liner. While the vehicle is off the illuminated entry feature can be activated in the following ways. Whenever a door is opened - When the vehicle is unlocked with a key - When the CTM receives a valid unlock signal from the RKE transmitter The illuminated entry will remain ON for 30 seconds after the last door is closed, turn OFF immediately after ignition is turned ON, or turn OFF when the CTM receives a LOCK message from the RKE transmitter. 15 Minute Illumination Timeout If the ignition is OFF and either front door is open, interior illumination will terminate after 15 minutes. If either front door is open and the ignition is turned in the RUN or ACCESSORY position, interior illumination will continue until the ignition is turned OFF. Once the ignition is OFF, if either front door remains open, the 15 minute interior illumination timeout will begin. Note: This timeout feature does not apply to either auxiliary door or the dome lamp switch which are hardwired to the courtesy lamps. The auxiliary door switches are also wired to the CTM to operate illuminated entry. Central Timer Module CENTRAL TIMER MODULE (CTM) The AB RAM VAN has two different body electrical systems, High Line and Base. The High Line utilizes a Central Timer Module (CTM) to provide the body features listed below. The CTM was designed to reduce cost, wiring complexity, and improve the system reliable. The CTM interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of information between modules and diagnostic capability using the DRB III. The CTM equipped vehicles can be identified by the sound of a Key-In Ignition CHIME. The Base AB RAM VAN body system is composed of individual modules. Because the stand-alone modules do not communicate on the CCD Bus, they cannot be diagnosed using the DRB. For concerns about the BASE AB VAN, refer to the appropriate service procedures. The Base version can be identified by the sound of the Key-In Ignition BUZZER. The CTM provides the following features: CCD Bus Communication - Chime - Courtesy Lamp Controls/Illuminated Entry - Enhanced Accident Response - Intermittent Wiper Delay - Power Door Locks W/RKE - Remote Keyless Entry (RKE) - Speed Sensitive Intermittent Wipers - Vehicle Theft Security System (VTSS) The module is located on the left center instrument panel support. It contains a white 18-way and a green 14-way connector. Central Timer Module Diagnostic Trouble Codes Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure Chime System Chime System The chime system is build into the CTM. The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for gauge problems and tell tale warnings. The CTM chime functions will have priority over the MIC chime requests. There are two chime rates, Low; 50 chimes per minute for reminders and High; 180 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the driver door is open or the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2314 headlights are left ON. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for the key-in, and headlamp warning, as long as the drivers door is open. The seat belt warning chime is activated for 4 to 6 seconds , and all other chime conditions will activate the chime once at the same time the warning light ON the cluster is illuminated. The chime will sound for the following conditions: High rate Key in Warning ignition off, key in ignition, driver's door open - Ignition off, headlamps ON, driver's door open Low rate Seat belt warning - 6 seconds after key on (6 to 8 chimes) or until seatbelt is buckled - Airbag lamp illuminated (3 times after prove-out) - ABS lamp illuminated (2 chimes after prove-out if equipped) - Check engine lamp illuminated (2 chimes after prove-out) - Check gauges lamp illuminated (2 chimes) - Engine Temp High - when gauge enters red zone (2 chimes) - Low fuel - when fuel level reaches 1/8 tank (2 chimes) - Low washer fluid (2 chimes) - Transmission Temperature High (2 chimes) If the ignition switch is turned to the RUN/START position and the driver's door is closed, then opened, the warning chime is defeated. This allows the doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the OFF position, then normal function will be restored. Description and Functional Operation DESCRIPTION AND FUNCTIONAL OPERATION The body system on the 1999 AB HIGH LINE consists of three modules that communicate over the CCD bus (Chrysler Collision Detection multiplex system). There are two additional modules, the Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are performed through the Serial Communication Interface of SCI, the same as previous years. All of the information about the functioning of all the system is organized, controlled, and communicated by (CCD Bus). Through the CCD bus, information about the operation of vehicle components and circuits is relayed quickly to the appropriate module(s). All modules receive all the information transmitted on the bus even though a module may not require all the information to perform it's function. It will only respond to messages "addressed" to it through a binary coding process. This method of data transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. DRB III Error Messages and Blank Screen DRB III ERROR MESSAGES AND BLANK SCREEN Under normal operation, the DRB will display one of only two error messages: User-Requested WARM Boot or - User-Requested COLD Boot If the DRB should display any other error message, record the entire display and call the MDS Hotline, or call for information and assistance at 1-800-825-8737. This is a sample of such an error message display: ver: 2.14 date: 26 Jul93 file: key_itf.cc date: Jul 26 1993 line: 548 err: Ox1 User-Requested COLD Boot Press MORE to switch between this display and the application screen. Press F4 when done noting information. DRB III Does Not Power Up (Blank Screen) If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (Data Link Connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, and inoperative DRB may be the result of a faulty cable or vehicle wiring. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2315 DRB III Scan Tool Display Is Not Visible Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition. Enhanced Accident Response (Highline CTM Only) ENHANCED ACCIDENT RESPONSE (Highline Only) If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The interior lights will be turned ON 10 seconds after getting zero speed message on the CCD bus. In addition to unlocking the doors, the lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "OFF" position, normal operation will resume. Diagnostics DIAGNOSTICS Gauges The instrument cluster will not store any DTC's. Because the engine controller PCM gathers all the gauge information and sends it to the cluster via the bus, it is the controller's responsibility to monitor these inputs and store DTC's for them. For this reason the first item to be checked regarding a gauge problem (except oil pressure) should be the engine controller for any DTC's relating to the gauge in question. There are DTC's associated with all the gauges except for the oil pressure gauge. When diagnosing gauges, the input that is used for gauge message (fuel level sender for example) must be valid. Because of OBD II requirements, most of the information used for monitoring the OBD II system happens to be the same information used by the controller to formulate the gauge bus messages. OBD II requirement state that the fuel level sender must be checked for rationality. This includes determining if the sending unit voltage is too high or too low or if the voltage hasn't changed over time. If the PCM has determined that the sender information isn't valid, it will send a diagnostic trouble code. The presence or absence of the fuel level sending code in the PCM is an important factor to determine whether a fuel gauge problem is in the sending unit or the cluster. The same situation is used in all cluster diagnostics related to gauge operation with the exception of the oil pressure gauge. OBD II requirements do not include oil pressure monitoring. Therefore, oil pressure diagnostic would dictate that a mechanical oil pressure gauge be attached to the engine for absolute verification of oil pressure readings. Hard Wired Lamps The cluster contains several hard wired lamps described earlier. The lamps are set up in two configurations. Either the cluster supplies power and ground is supplied by the circuit being monitored or the lamp is supplied ground by the cluster and power comes from a module or other device. Refer to the schematic for the specific details on the lamp in question. Verification of the bulb filament may be required in cases of an inoperative lamp. This will require removal of the cluster and bulb in question. NOTE: THE BRAKE, TRANS TEMP, CHECK GAUGES, SEAT BELTS AND AIRBAG WARNING LAMPS ARE LED'S, ALL OTHER ARE BULBS. IF ANY LED'S ARE DEFECTIVE,THE INSTRUMENT CLUSTER MUST BE REPLACED. CCD Controlled Lamps The cluster contains several CCD controlled lamps as described earlier. These lamps are part of the diagnostic self-test. When entering the self-test mode, operation of these lamps can be observed. If the bulb fails to operate during the self-test and the bulb filament is good, the cluster assembly will need to be replaced. NOTE: A FLASHING SEAT BELT LAMP INDICATES THAT THE AIRBAG WARNING LAMP IS NOT OPERATING PROPERLY. Mechanical Instrument Cluster Description MECHANICAL INSTRUMENT CLUSTER (MIC) Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2316 The Ram Van uses a standard MIC in all of it's U.S. vehicles. The cluster has 5 gauges and 15 indicator lamps. The gauges are positioned with information received over the CCD bus. Some of the indicator lamps are hardwired and the cluster using CCD bus information controls some. The MIC is hardwired to the CTM to provide the warning lamp announcement chimes. There is a self-test available for the cluster that will actuate all the gauges to their calibration points. The self test will not run if the cluster sees engine RPM or vehicle speed. The test will light all CCD controlled lamps for verification of lamp operation. It also forces the odometer Liquid Crystal Display (LCD) to perform a segment check. The self test routine can be entered by pressing and holding the trip reset button while rotating the ignition key from the OFF position to the ON position. When the word "check" appears, release the button and the test will continue. The cluster will provide bus bias termination and the engine controller provides a second termination. If the cluster is disconnected, the bus will not be biased. The cluster will be serviced as an assembly. There will be limited parts available, bulbs and sockets, the front lens, the trip odometer system cover and the rear cover assembly. No internal parts of the cluster will be serviceable. Normal Operation At key ON, the cluster will light the low fuel, seat belt, check gauges, and airbag. As the key is turned farther towards the start position, the check engine, ABS (if equipped) and brake warning lamp will illuminate. The liquid crystal display (LCD) will indicate the mileage stored inside the cluster. If there is a bus failure and the cluster cannot receive distance pulses from the engine controller, the cluster will display the last mileage stored until the ignition is turned OFF. If the cluster is receiving bus messages but is unable to display odometer information because of an internal failure, the odometer display will be blank. Dimming is handled by the potentiometer that controls instrumentation illumination. Lamps (Hardwired) The following lamps are hardwired in the cluster and are not part of the self-test. High Beam - Left Turn Signal - Right Turn Signal - Brake (comes ON during self-test) - Low Wash (comes during self-test) - Seat Belt (comes ON during self-test) Lamps (CCD) The cluster via CCD messages controls the following lamps. They are actuated during the self-test procedure. ABS lamps - Airbag - Check Engine - Check Gauges - Cruise Control Lamp - Security - Trans Temp - O/D OFF - Low Fuel Warning - Internally controlled by the cluster; not CCD NOTE: THE TURN SIGNALS, HIGH BEAM INDICATOR, SEAT BELT WARNING LAMP,LOW WASHER WARNING LAMP, AND BRAKE WARNING LAMP ARE HARDWIRED TO THE CLUSTER. Power Door Lock System POWER DOOR LOCKS The CTM controls the door lock actuation assemblies to handle locking and unlocking with the interior door lock switches or the RKE transmitter (key fob). There is also a door lock inhibit feature that prevents the power locking of the doors if the key is in the ignition or the headlamps are ON and the left front door is open. However, the doors can still be locked using the RKE transmitter which allows the engine to run for warm up purposes. Automatic (Rolling) Door Locks When the doors are closed and the vehicle speed exceeds 15 MPH due to engine power (not just rolling) and all doors are closed, the CTM will lock the doors. The vehicle is shipped with the automatic door lock feature disabled, but may be enabled using the DRB. Door Lock Delay If the CTM receives a signal to lock the doors and one or both of the auxiliary doors (side or rear) are open, the front doors will still lock. Five seconds after both of the auxiliary door are closed, the CTM will recycle the lock function. Remote Keyless Entry The CTM is compatible with a two button TRW RKE transmitter (keyfob). Two pre-programmed transmitters will be supplied with each vehicle. The CTM is capable of retaining up to four transmitters which can be programmed using the DRB. When a signal encoded with the correct vehicle access code is received and contains a valid message, the CTM will activate the corresponding relay to lock or unlock the doors. When an unlock Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2317 message is sent, all the doors will unlock, the VTSS will disarm and the illuminated entry will be activated. When a lock message is sent and all the doors are closed, all the doors will lock, the VTSS arming sequence will begin and the illuminated entry will turn OFF. Horn chirp When the doors are locked using the transmitter, a horn chirp will sound to let the customer know the doors were locked. The vehicle will be shipped with this function disabled but may be enabled using the DRB. The duration of the horn chirp can also be changed using the DRB. Trouble Codes AIRBAG DIAGNOSTIC TROUBLE CODES Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists, diagnostic priority should be given to the active codes. Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the trouble codes. It is not necessary to perform all of the tests in this book to diagnose an individual code. Always begin by reading the diagnostic trouble codes using the DRB III. This will direct you to the specific test(s) that must be performed Active diagnostic trouble codes for the airbag system are not permanent and will change the moment the reason for the code is corrected. In certain test procedures within this , diagnostic trouble codes are used as a diagnostic tool. Active Codes The code becomes active as soon as the malfunction is detected or key-OFF, whichever occurs first. An active trouble code indicates an on-going malfunction. This means that the defect is currently there every time the airbag control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected. With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present. The seat belt lamp replaces the airbag lamp if the airbag lamp is defective. The seat belt lamp pulses ON and OFF 30 times if the airbag warning lamp is defective. Stored Codes Airbag codes are automatically stored in the ACM's memory as soon as the malfunction is detected. The exception is the "Loss of Ignition Run Only" code which is an active code only. A "stored" code indicates there was an active code present sometime. However, the code currently may not be present as an active code, although another active code could be. When a trouble code occurs, the airbag warning lamp illuminates for 12 seconds minimum (even if the problem existed for less than 12 seconds). The code is stored, along with the time in minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. The minimum time shown for any code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two minutes 13 seconds, for example, would be three minutes. If malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored code. If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the problem. In this case, the stored code can indicate an area to inspect. If no obvious problems are found, erase stored codes, and with the ignition "ON" wiggle the wire harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes periodically as you work through the system. This procedure may uncover a malfunction that is difficult to locate. Airbag Trouble Codes The Airbag Control Module may report any of the following diagnostic trouble codes. For the following codes, replace the Airbag Control Module (ACM) even if set intermittently: ACM ACCELEROMETER - ACM OUTPUT DRIVER CIRCUIT OPEN - ACM INTERNAL DIAGNOSTIC CODE # 1 - ACM INTERNAL DIAGNOSTIC CODE # 2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2318 - ACM STORED ENERGY - ACM OUTPUT DRIVER For these codes, refer to the appropriate diagnostic procedure: Cluster Message Mismatch Driver Squib Circuit Open Driver Squib Circuit Shorted Driver Squib Circuit Shorted to Battery Driver Squib Circuit Shorted to Ground Loss of Ignition Run Only Loss of Ignition Run/Start NO Cluster CCD Message No CCD Communication Passenger Squib Circuit Open Passenger Squib Circuit Shorted Passenger Squib Circuit Shorted to Battery Passenger Squib Circuit Shorted to Ground Warning Lamp Open/Shorted Vehicle Communication VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the higher priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus -" (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a voltage divider network located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems use more than one. Some modules are capable of biasing and terminating the bus by themselves. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. Without termination, voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. In the 1999 Ram Van, the instrument cluster supplies bus bias and termination and the PCM supplies an additional point of termination. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLES ON-BOARD DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING.IF THERE IS A PROBLEM, REFER TO THE VEHICLE COMMUNICATION. Vehicle Theft Security System (VTSS) VEHICLE THEFT SECURITY SYSTEM (VTSS) The VTSS will monitor the states of the ignition, door lock signal, and all other doors to alert against unauthorized entry into the vehicle. The VTSS will be enabled at the assembly plant. To prevent arming of the VTSS during assembly and the shipping process, the vehicle must be started 20 times before the VTSS will operate properly. Arming the VTSS To arm the system, the ignition must be OFF and all doors must be closed and locked using either the power door lock switches or the RKE transmitter. Using a key or pressing the mechanical lock soldier will not initiate arming the VTSS. The delay lock feature will delay the arming process until all doors are closed. Once the VTSS begins to arm, the CTM will activate the security lamp output at a 1 Hz rate. During this process the arming process will terminate if the ignition is turned ON, if a door is opened, if the doors are unlocked using the door lock switch or the RKE transmitter, or if the front doors are unlocked using the key. After fifteen seconds of the arming process, the security lamp will go OFF and the VTSS will be armed. Once the vehicle is armed the ignition may be turned to the accessory position (to listen to radio, etc.) without triggering the alarm. The VTSS can only be disarmed using the key or the RKE transmitter. Triggering the VTSS Once the VTSS is armed, the alarm will trigger if any of the doors are opened or if the key is turned the Run/Start position. When triggered, the CTM will instruct the PCM to turn OFF the engine after two seconds and will pulse the horn and headlamps at a specified duty cycle and frequency. The audible (horn) warning will continue for three minutes then terminate. The visual (headlamps) warning will continue for fifteen additional minutes then terminate. The engine will continue to start and quit until the VTSS is disarmed. Tamper Alert If the VTSS was triggered during the last armed period, the next time it is disarmed the CTM will activate three horn chirps. To determine what caused the alarm to be tripped, using the DRB select "Theft Alarm" "Monitor Display" and observe: "Alarm Tripped by". This is a great tool to Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2319 use when a customer complains that the alarm went OFF and cannot determine what triggered it. Warnings WARNINGS Vehicle Damage Warnings Before disconnecting any control module, make sure the ignition is OFF. Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected. Road Testing A Complaint Vehicle Some complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic code or symptom condition. CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE REASSEMBLED DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB SCREEN WHILE IN MOTION.DO NOT HANG THE DRB FROM THE REAR VIEW MIRROR OR OPERATE IT YOURSELF.HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB. Wiper System WINDSHIELD WIPERS Feature Description The Ram Van equipped with a CTM will utilize speed sensitive intermittent wipe and wipe after wash function. The driver selects the Wiper function via a Steering Column mounted Stalk Switch. The Wiper system is operational whenever the ignition switch is in the Run or Accessory positions only (not during engine crank). The low and high speeds are controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as selected by the driver, and immediate wipe of the windshield takes place and the new delay interval is implemented. An Intermittent Wipe cycle consists of operating the Wipers in the Low Speed mode for one cycle, then executing a delay time. The delay time available to the driver is adjustable from 1/2 second to 18 seconds. Speed Sensitive Intermittent Wipe Operation Speed Intermittent Wipe is operational whenever the Ignition Switch is in either the RUN or ACCESSORY positions, and the voltage ON the CKT name input is greater than 4.5 VDC. The resistance selected by the stalk switch is used to set the delay time between wipe cycles. The Intermittent Wipe Delay Time is also adjusted based upon Vehicle Speed. When the Vehicle Speed is < 10 MPH then the driver selected Delay Time is doubled providing a range from 1 second to 36 seconds. When the vehicle speed is > 10 MPH then the driver selected Delay Time is not adjusted. An immediate Low Speed mode Wipe cycle will occur and a new Delay Time interval will start if the driver changes the current selected Delay Time to a shorter interval. The speed signal is provided to the CTM from the PCM over the CCD bus. Wipe after Wash Operation Wipe after Wash operation activates the Wiper system when the Wash button is pressed. Wiper after Wash operation is available while the wiper switch is OFF or in Intermittent mode, and operates the Wipers in a Low Speed continuous cycling mode while the Wash button is held on. After the Wash button is released, 2 additional complete cycles are performed at Low Speed. The Wiper system returns to the previous mode of operation following the completion of the additional Wipe cycles. Self Calibration A self calibration feature is used to eliminate performance variations due to tolerances in the resistances of the intermittent wiper switch. Following a power on reset, a default value is copied to a battery backed RAM memory location. If a valid resistance value greater than the current battery backed compensation value is measured during intermittent wiper operation, and it is present for 8 consecutive samples, the compensation value is replaced by the average of the compensation value and the new resistance value. This compensation value is used to calculate the intermittent wiper delay, using the following formula: Delay in seconds = 0.5 + 17.5* (resistance value/ compensation value) Three EEPROM locations have been provided to allow for optional calibration of the intermittent wipers. One location specifies a constant which will override the battery backed compensation value. The other locations specify constants which will override the default offset and slope used in converting resistance to time delay. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 2320 Failed Wiper Park Switch A failed Wiper Park Switch is determined by the CTM "C1" PIN # 11 input remaining high for eight seconds when the wiper system is in intermittent mode. Once detected, a code flag will be set in the EEPROM fault record byte. Once the Failed Wiper Park Switch fault is set, the intermittent wiper function will not operate until a low is seen on the CTM "C1" PIN # 11 input with the ignition ON. The code flag may only be cleared manually using a DRB. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures Body Control Module: Symptom Related Diagnostic Procedures Chime Inoperative at All Times SYMPTOM * CHIME INOPERATIVE AT ALL TIMES POSSIBLE CAUSES - Chime inoperative at all times Chime Inoperative With Any Warning Lamp on SYMPTOM * CHIME INOPERATIVE WITH ANY WARNING LAMP ON POSSIBLE CAUSES - Tone request signal circuit open - Instrument cluster defective - Central Timer Module defective Chime Inoperative With Exterior Lamps On SYMPTOM * CHIME INOPERATIVE WITH EXTERIOR LAMPS POSSIBLE CAUSES - Driver door ajar switch status no change - Left door ajar switch circuit open Chime Inoperative With Key In Ignition & Driver Door Open SYMPTOM * CHIME INOPERATIVE WITH KEY IN IGNITION, DRIVER'S DOOR OPEN POSSIBLE CAUSES - Driver door switch status not changing - Key in ignition switch sense circuit open - Defective Central Timer Module - Ignition switch defective Chime Inoperative With Only One Warning Lamp SYMPTOM * CHIME INOPERATIVE WITH ONLY ONE WARNING LAMP POSSIBLE CAUSES - Oil pressure sensor defective - Oil pressure sense circuit open - Powertrain Control Module defective - Cooling system operation faulty - DRB not showing PCM active on Bus - DRB shows ECT sensor voltage too high - DRB shows ECT sensor voltage too low Chime Remains on With the Ignition on SYMPTOM * CHIME REMAINS ON WITH THE IGNITION ON POSSIBLE CAUSES - Chime staying ON with ignition ON - Tone request signal circuit short - Central Timer Module defective - Instrument cluster defective Chime Sounds With Driver's Door Open SYMPTOM * CHIME SOUNDS WITH DRIVER'S DOOR OPEN POSSIBLE CAUSES Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Body Control Module > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures > Page 2323 - Chime sounds with key removed - Key in ignition switch sense circuit short - Left front door ajar switch sense circuit short - Driver door misaligned - Central Timer Module defective Courtesy Lamp Inoperative With Left Front Door SYMPTOM * COURTESY LAMPS INOPERATIVE FROM LEFT FRONT DOOR TEST NOTE This symptom is diagnosed using the test * OPEN DRIVER DOOR AJAR.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2343 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2344 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2345 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2346 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2347 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2348 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number for the subsequent diagram will match a listed group shown. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2349 Connector and Terminal Replacement 1. Disconnect battery. 2. Disconnect the connector (that is to be repaired) from its mating half/component. 3. Cut off the existing wire connector directly behind the insulator.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2358 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2359 3.

Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2360 Powertrain Control Module: Connector Views Powertrain Control Module Connectors Powertrain Control Module C1 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2361 Powertrain Control Module C2 Powertrain Control Module C3 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Description and Operation > Engine Control Powertrain Control Module: Description and Operation Engine Control POWERTRAIN CONTROL MODULE Powertrain Control Module (PCM) The Powertrain Control Module (PCM) is located in the engine compartment.

The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Refer to Camshaft Position Sensor, Ignition System for more information. CAMSHAFT POSITION SENSOR The camshaft position sensor is located in the distributor on all engines. The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal 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. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Locations > Page 2390 Camshaft Position Sensor: Service and Repair CAMSHAFT POSITION SENSOR Camshaft Position Sensor The camshaft position sensor is located in the distributor.

The sensor provides an input voltage to the powertrain control module (PCM) relating coolant temperature. The PCM uses this input along with inputs from other sensors to determine injector pulse width and ignition timing.

The sensors produce voltages from 0 to 1 volt, depending upon the oxygen content of the exhaust gas in the exhaust manifold. When a large amount of oxygen is present (caused by a lean air/fuel mixture), the sensors produces a low voltage. When there is a lesser amount present (rich air/fuel mixture) it produces a higher voltage. By monitoring the oxygen content and converting it to electrical voltage, the sensors act as a rich-lean switch. The oxygen sensors are equipped with a heating element that keeps the sensors at proper operating temperature during all operating modes. Maintaining correct sensor temperature at all times allows the system to enter into closed loop operation sooner. Also, it allows the system to remain in closed loop operation during periods of extended idle. In closed Loop operation, the PCM monitors the O2S sensor input (along with other inputs) and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values and inputs from other sensors. The Automatic Shutdown (ASD) relay supplies battery voltage to both the upstream and downstream heated oxygen sensors. The oxygen sensors are equipped with a heating element The heating elements reduce the time required for the sensors to reach operating temperature. UPSTREAM HEATED OXYGEN SENSOR Heated Oxygen Sensors The upstream O2S sensor is located in the inlet end of the catalytic converter. It provides an input voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The PCM uses this information to fine tune the air/fuel ratio by adjusting injector pulse width. DOWNSTREAM HEATED OXYGEN SENSOR The downstream heated oxygen sensor threads into the outlet end of the catalytic convertor. The downstream heated oxygen sensor input is used to detect catalytic convertor deterioration. As the convertor deteriorates, the input from the downstream sensor begins to match the upstream sensor input except for a slight time delay. By comparing the downstream heated oxygen sensor input to the input from the upstream sensor, the PCM calculates catalytic convertor efficiency. When the catalytic converter efficiency drops below emission standards, the PCM stores a diagnostic trouble code and illuminates the Malfunction Indicator Lamp (MIL). For more information., refer to Emission Control Systems. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Locations > Page 2446 Oxygen Sensor: Testing and Inspection To perform a complete test of the O2S sensors and their circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures.

The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2468 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2469 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2470 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2471 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2472 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2473 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2483 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2484 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2485 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Page 2486 Vehicle Speed Sensor: Description and Operation VEHICLE SPEED AND DISTANCE - PCM INPUT Vehicle speed and distance covered are measured by the Rear Wheel Speed Sensor.

The TPS is a variable resistor that provides the powertrain control module (PCM) with an input signal (voltage) that represents throttle blade position. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Specifications > Page 2496 Throttle Position Sensor: Testing and Inspection To perform a complete test of the TPS and its circuitry; refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures. To test the TPS only, refer to the following: The TPS can be tested with a digital voltmeter. The center terminal of the TPS is the output terminal. With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT). At idle, TPS output voltage should must be greater than 0.26 volts and less than 0.95 volts. At wide open throttle, TPS output voltage must be less than 4.49 volts. The output voltage should increase gradually as the throttle plate is slowly opened from idle to WOT. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Specifications > Page 2497 Throttle Position Sensor: Service and Repair THROTTLE POSITION SENSOR (TPS) MAP Sensor, TP Sensor, IAC Motor The TPS is located on the side of the throttle body.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2510 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2511 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2512 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2513 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2514 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2515 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number for the subsequent diagram will match a listed group shown. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2516 Connector and Terminal Replacement 1.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2525 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2526 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2527 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Page 2528 Vehicle Speed Sensor: Description and Operation VEHICLE SPEED AND DISTANCE - PCM INPUT Vehicle speed and distance covered are measured by the Rear Wheel Speed Sensor.

It also informs the PCM what voltage level is supplied to the ignition coil and fuel injectors. If battery voltage is low, the PCM will increase injector pulse width (period of time that the injector is energized). This is done to compensate for the reduced flow through injector caused by the lowered voltage. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Description and Operation Catalytic Converter: Description and Operation CATALYTIC 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Service and Repair > Removal and Installation Catalytic Converter: Service and Repair Removal and Installation CATALYTIC CONVERTER WITH PIPES REMOVAL 1.

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.

A thorough inspection for pinched, kinked, or disconnected supply vacuum lines (as currently listed in the Powertrain Diagnostic Procedures) is a critical step in diagnosing DTC P1494 (LDP SW OR MECHANICAL FAULT). Additionally, the other evaporative leak faults (DTC P0442 SMALL LEAK, P0455 - LARGE LEAK, and P0456 - VERY SMALL LEAK) should have the supply vacuum lines examined for pinches or kinks prior to any LDP component replacement. The supply vacuum lines should be checked from the engine compartment all the way to the fuel tank, including the LDP and purge system.

Leaks in the system, even small ones, can allow fuel vapors to escape into the atmosphere. Government regulations require on-board 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2566 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. Leak Detection Pump (LDP) Components 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' H20(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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2567 LDP AT REST (NOT POWERED) 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2568 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2569 DIAPHRAGM DOWNWARD MOVEMENT 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 PGM 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 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2570 Leak Detection Pump: Testing and Inspection ENABLING CONDITIONS TO RUN EVAP LEAK DETECTION TEST NOTE: The following values are approximate and vehicle specific. Use the values seen in pre test/monitor test screen on the DRB III. See TSB 25-02-98 for more detail 1. Cold start: with ambient temperature (obtained from modeling the inlet air temperature sensor on passenger vehicles and the battery temperature sensor on Jeep & truck vehicles) between 4C° (40° F) and 32° C (90° F) for 0.040 leak. Between 4C° (40° F) and 29° C (85° F) for 0.020 leak. 2. Engine coolant temperature within:-12° to -8°C (10° to 18°F) of battery/ambient. 3. Battery voltage between 10 and 15 volts. NOTE: If battery voltage drops below 10 volts for more than 5 seconds during engine cranking, the EVAP leak detection test will not run. 4. Low fuel warning light off (fuel level must be between 15% and 85% for 0.040 leak and 30% and 85% for 0.020 leak). 5. MAP sensor reading 22 in Hg or above (This is the manifold absolute pressure, not vacuum). 6. No engine stall during test.

If the EVAP system has residual pressure, the LDP diaphragm may be up. This could result in the LDP reed switch being open when the key is turned to "ON" and a P1494 fault could be set because the PCM is expecting the reed switch to be closed. After the key is turned "ON", the PCM immediately tests the LDP solenoid circuit for electrical faults. If a fault is detected, DTC P1495 will set, the MIL will illuminate, and the remaining EVAP Leak Detection Test is canceled. NOTE: If battery temperature is not within range, or if the engine coolant temperature is not within a specified range of the battery temperature, the PCM will not run tests for DTC P1494, P1486, P0442, P0455 and P0441. These temperature calibrations may be different between models. FIGURE 6 SECTION 2 If DTC P1495 is not set, the PCM will check for DTC P1494. If the LDP reed switch was closed when the key was turned to "ON", the PCM energizes the LDP solenoid for up to 8 seconds and monitors the LDP switch. As the LDP diaphragm is pulled up by engine vacuum, the LDP reed switch should change from closed to open. If it does not, the PCM sets a temporary fault (P1494) in memory, and waits until the next time the Enabling Conditions are met to run the test again. If this is again detected, P1494 is stored and the MIL is illuminated. If the problem is not detected during the next enabling cycle, the temporary fault will be cleared. However, if the PCM detects the reed switch open when the key is turned to "ON", the PCM must determine if this condition is due to residual pressure in the EVAP system, or an actual fault. The PCM stores information in memory on EVAP system purging from previous engine run or drive cycles. If little or no purging took place, residual pressure could be holding the LDP diaphragm up, causing the LDP switch to be open. Since this is not a malfunction, the PCM cancels the EVAP Leak Detection Test without setting the temporary fault. If there was sufficient purging during the previous cycle to eliminate EVAP system pressure, the PCM judges that this is a malfunction and sets a temporary fault in memory. The next time that the Enabling Conditions are met, the test will run again. If the fault is again detected, the MIL will Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2572 illuminate and DTC 1494 will be stored. If the fault is not detected, the temporary fault will be cleared. FIGURE 6 SECTION 3 If no fault has been detected so far, the PCM begins testing for possible blockage in the EVAP system between the LDP and the fuel tank. This is done by monitoring the time required for the LDP to pump air into the EVAP system during two to three pump cycles. If no blockage is present, the LDP diaphragm is able to quickly pump air out of the LDP each time the PCM turns oft the LDP solenoid. If a blockage is present, the PCM detects that the LDP takes longer to complete each pump cycle. If the pump cycles take longer than expected (approximately 6 to 10 seconds) the PCM will suspect a blockage. On the next drive when Enabling Conditions are met, the test will run again. If blockage is again detected, P1486 is stored, and the MIL is illuminated. FIGURE 6 SECTION 4 After the LDP blockage tests are completed, the PCM then tests for EVAP system leakage. First, the PCM commands the LDP to rapidly pump for 20 to 50 seconds (depending on fuel level) to build pressure in the EVAP system. This evaluates the system J18-24-0 to see if it can be sufficiently pressurized. This evaluation (rapid pump cycling) may occur several times prior to leak checking. The LDP reed switch does not close and open during rapid pumping because the diaphragm does not travel through its full range during this part of the test. FIGURE 6 SECTION 5 Next, the PCM performs one or more test cycles by monitoring the time required for the LDP reed switch to close (diaphragm to drop) after the LDP solenoid is turned off. If the switch does not close, or closes after a long delay, it means that the system does not have any significant leakage and the EVAP Leak Detection Test is complete. However, if the LDP reed switch closes quickly, there may be a leak or the fuel level may be low enough that the LDP must pump more to finish pressurizing the EVAP system. In this case, the PCM will rapidly pump the LDP again to build pressure in the EVAP system, and follow that by monitoring the time needed for several LDP test cycles. This process of rapid pumping followed by several LDP test cycles may repeat several times before the PCM judges that a leak is present. When leaks are present, the LDP test cycle time will be inversely proportional to the size of the leak. The larger the leak, the shorter the test cycle time. The smaller the leak, the longer the test cycle time. DTC's may be set when a leak as small as 0.5 mm (0.020") diameter is present. If the system detects a leak, a temporary fault will be stored in PCM memory. The time it takes to detect a .020, .040, or Large leak is based on calibrations that vary from model to model. The important point to remember is if a leak is again detected on the next EVAP Leak Detection Test, the MIL will illuminate and a DTC will be stored based on the size of leak detected. If no leak is detected during the next test, the temporary fault will be cleared. DIAGNOSTIC TIPS During diagnosis, you can compare the LDP solenoid activity with the monitor sequence in Figure 6. If the PCM detects a problem that could set a DTC, the testing is halted and LDP solenoid activity will stop. As each section of the test begins, it indicates that the previous section passed successfully. By watching to see which tests complete, you can see if any conditions are present that the PCM considers abnormal. For example, if the LDP solenoid is energized for the test cycles to test for blockage (P1486), it means that the LDP has already passed its test for P1494. Then, if the PCM detects a possible blockage, it will set a temporary fault without turning on the MIL and continue the leak portion of the test. However, the PCM will assume that the system is already pressurized and skip the rapid pump cycles. Always diagnose leaks, if possible, before disconnecting connections. Disconnecting connections may mask a leak condition. Keep in mind that if the purge solenoid seat is leaking, it could go undetected since the leak would end up in the intake manifold. Disconnect the purge solenoid at the manifold when leak checking. In addition, a pinched hose fault (P1486) could set if the purge solenoid does not purge the fuel system properly (blocked seat). The purge solenoid must vent the fuel system prior to the LDP system test. If the purge solenoid cannot properly vent the system the LDP cannot properly complete the test for P1486 and this fault can set due to pressure being in the EVAP system during the test sequence. Multiple actuation's of the DRB Ill® Leak Detection Pump (LDP) Monitor Test can hide a 0.020 leak because of excess vapor generation. Additionally, any source for additional vapor generation can hide a small leak in the EVAP system. Excess vapor generation can delay the fall of the LDP diaphragm thus hiding the small leak. An example of this condition could be bringing a cold vehicle into a warm shop for testing or high ambient temperatures. Fully plugged and partially plugged underhood vacuum lines have been known to set MIL conditions. P1494 and P0456 can be set for this reason. Always, thoroughly, check plumbing for pinches or blockage before condemning components. TEST EQUIPMENT The Evaporative Emission Leak Detector (EELD) Miller Special Tool 8404 is capable of visually detecting leaks in the evaporative system and will take Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2573 the place of the ultrasonic leak detector 6917A. The EELD utilizes shop air and a smoke generator to visually detect leaks down to 0.020 or smaller. The food grade oil used to make the smoke includes an UV trace dye that will leave telltale signs of the leak under a black light. This is helpful when components have to be removed to determine the exact leak location. For detailed test instructions, follow the operators manual packaged with the EELD. IMPORTANT Be sure that the PCM has the latest software update. Reprogram as indicated by any applicable Technical Service Bulletin.

Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1-2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by: - Fuel pressure bleeding past a fuel injector(s). - Fuel pressure bleeding past the check valve in the fuel pump module. 1. Disconnect the fuel inlet line at fuel rail. Refer to Fuel Tubes/Lines/Hoses and Clamps for procedures. On some engines, air cleaner housing removal may be necessary before fuel line disconnection. 2. Obtain correct Fuel Line Pressure Test Adapter Tool Hose. Tool number 6539 is used for 5/16" fuel lines and tool number 6631 is used for 3/8" fuel lines. Connecting Adapter Tool-Typical 3. Connect correct Fuel Line Pressure Test Adapter Tool Hose between disconnected fuel line and fuel rail. 4. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test port on the appropriate Adaptor Tool. The fittings on both tools must be in good condition and free from any small leaks before performing the proceeding test. 5. Start engine and bring to normal operating temperature. 6. Observe test gauge. Normal operating pressure should be 339 kPa + 34 kPa (49.2 psi + 5 psi). 7. Shut engine off. 8. Pressure should not fall below 30 psi for five minutes. 9. If pressure falls below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is leaking. 10. Again, start engine and bring to normal operating temperature. 11. Shut engine off. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pressure > System Information > Specifications > Page 2592 12.

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. An individual fuel injector is used for each individual cylinder. The top (fuel entry) end of the injector is attached into an opening on the fuel rail, 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. During start up, battery voltage is supplied to the injectors through the ASD relay. When the engine is operating, voltage is supplied by the charging system. The PCM determines injector pulse width based on various inputs.

BEFORE DISCONNECTING FUEL LINE AT FUEL RAIL, THIS PRESSURE MUST BE RELEASED. REFER TO THE FUEL SYSTEM PRESSURE RELEASE PROCEDURE . Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pressure > System Information > Specifications > Page 2675 Fuel Pressure: Testing and Inspection FUEL PRESSURE LEAK DOWN TEST Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity Test. Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1-2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by: - Fuel pressure bleeding past a fuel injector(s). - Fuel pressure bleeding past the check valve in the fuel pump module. 1. Disconnect the fuel inlet line at fuel rail. Refer to Fuel Tubes/Lines/Hoses and Clamps for procedures. On some engines, air cleaner housing removal may be necessary before fuel line disconnection. 2. Obtain correct Fuel Line Pressure Test Adapter Tool Hose. Tool number 6539 is used for 5/16" fuel lines and tool number 6631 is used for 3/8" fuel lines. Connecting Adapter Tool-Typical 3. Connect correct Fuel Line Pressure Test Adapter Tool Hose between disconnected fuel line and fuel rail. 4. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test port on the appropriate Adaptor Tool. The fittings on both tools must be in good condition and free from any small leaks before performing the proceeding test. 5. Start engine and bring to normal operating temperature. 6. Observe test gauge. Normal operating pressure should be 339 kPa + 34 kPa (49.2 psi + 5 psi). 7. Shut engine off. 8. Pressure should not fall below 30 psi for five minutes. 9. If pressure falls below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is leaking. 10. Again, start engine and bring to normal operating temperature. 11. Shut engine off. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pressure > System Information > Specifications > Page 2676 12. Testing for fuel injector or fuel rail leakage: Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking. 13. Testing for fuel pump cheek valve, filter/regulator check valve or fuel tube/line leakage: Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line. If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump or filter/regulator may be leaking. NOTE: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A slow loss of pressure usually indicates a defective check valve in the electric fuel pump.

The fuel pump module contains the following components: - A combination fuel filter/fuel pressure regulator - Electric fuel pump - Fuel pump reservoir - A separate fuel pick-up filter (strainer) - Fuel gauge sending unit (fuel level sensor) - Fuel supply line connection at filter/regulator - A plastic threaded locknut to retain pump module to fuel tank - A gasket between tank flange and module The fuel gauge sending unit (fuel level sensor), and pick-up filter (at bottom of module) may be serviced separately. If the electrical fuel pump requires service, the entire fuel pump module must be replaced. The fuel filter/fuel pressure regulator may be serviced separately. Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for additional information. FUEL GAUGE SENDING UNIT 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). The resistor track is used to send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for OBD II emission requirements. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank > Fuel Gauge Sender > Component Information > Specifications > Page 2711 For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and arm move down. This increases the sending unit resistance causing the fuel gauge to read empty. After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading. For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the sending unit to the PCM 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 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 Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank > Fuel Gauge Sender > Component Information > Specifications > Page 2712 Fuel Gauge Sender: Testing and Inspection The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down, electrical resistance will change. Refer to Instrument Panel and Gauges for Fuel Gauge testing. To test the gauge sending unit only, it must be removed from vehicle. The unit is part of the fuel pump module. Refer to Fuel Pump Module Removal/ Installation for procedures. Measure the resistance across the sending unit terminals.

Visually inspect the cap for cracks, carbon paths, broken towers or damaged rotor button. Also check for white deposits on the inside (caused by condensation entering the cap through cracks). Replace any cap that displays charred or eroded terminals. The machined surface of a terminal end (faces toward rotor) will indicate some evidence of erosion from normal operation. Examine the terminal ends for evidence of mechanical interference with the rotor tip. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Distributor, Ignition > Ignition Rotor > Component Information > Testing and Inspection Ignition Rotor: Testing and Inspection Rotor Inspection-Typical Visually inspect the rotor for cracks, evidence of corrosion or the effects of arcing on the metal tip. Also check for evidence of mechanical interference with the cap. Some charring is normal on the end of the metal tip. The silicone-dielectric-varnish-compound applied to the rotor tip for radio interference noise suppression, will appear charred. This is normal. Do not remove the charred compound. Test the spring for insufficient tension. Replace a rotor that displays any of these adverse conditions. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Cable > Component Information > Technical Service Bulletins > Customer Interest for Ignition Cable: > 18-48-98 > Dec > 98 > Ignition System - Cross Fire/Ignition Wire Induction Technical Service Bulletin # 18-48-98 Date: 981230 Ignition System - Cross Fire/Ignition Wire Induction NO: 18-48-98 GROUP: Vehicle Performance DATE: Dec. 30, 1998 SUBJECT: Ignition System Cross Fire/Secondary Ignition Wire Induction MODELS: 1994 - 1999 (AN) Dakota 1994 - 1999 (BR/BE)Ram Truck 1998 - 1999 (DN) Durango 1995 - 1998 (ZG) Grand Cherokee (International Market) 1994 - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A 3.9L, 5.2L, OR 5.9L ENGINE.

These 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Cable > Component Information > Technical Service Bulletins > Page 2850 Ignition Cable: Testing and Inspection IGNITION CABLES Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and spark plugs. Terminals should be fully seated. The insulators should be in good condition and should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are cracked or torn must be replaced. Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the cables dry. Check for brittle or cracked insulation. Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable boot and spark plug. These shields protect the spark plug boots from damage (due to intense engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat shield. Testing When testing secondary cables for damage with an oscilloscope, follow the instructions of the equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as follows: CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during testing. This may cause possible heat damage to the catalytic converter. Total test time must not exceed ten minutes. With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to a good engine ground. If the cable and spark plug are in good condition, the engine rpm should drop and the engine will run poorly. If engine rpm does not drop, the cable and/or spark plug may not be operating properly and should be replaced. check engine cylinder compression. With the engine not running, connect one end of a test probe to a good ground. Start the engine and run the other end of the test probe along the entire length of all spark plug cables. If cables are cracked or punctured, there will be a noticeable spark jump from the damaged area to the test probe. The cable running from the ignition coil to the distributor cap can be checked in the same manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket. Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped, remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable. Test all spark plug cables in this manner.

The Powertrain Control Module (PCM) opens and closes the ignition coil ground circuit for ignition coil operation. Base ignition timing is not adjustable on any engine. By controlling the coil ground circuit, 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 ignition coil is not oil filled. The windings are embedded in an epoxy compound. This provides heat and vibration resistance that allows the ignition coil to be mounted on the engine. IGNITION COIL - PCM OUTPUT System voltage is supplied to the ignition coil positive terminal. The powertrain control module (PCM) operates the ignition coil. Base (initial) ignition timing is not adjustable. The PCM adjusts ignition timing to meet changing engine operating conditions. Ignition Coil-Typical (5.2/5.9L) The ignition coil is located near the front of the right cylinder head.

Also refer to the appropriate Powertrain Diagnostics Procedures. To test the coil only, refer to the following: Ignition Coil-Typical (5.2/5.9L) The ignition coil is designed to operate without an external ballast resistor. Ignition Coil Resistance Inspect the ignition coil for arcing. Test the coil according to coil tester manufacturer's instructions. Test the coil primary and secondary resistance. Replace any coil that does not meet specifications. Refer to the IGNITION COIL RESISTANCE chart. If the ignition coil is being replaced, the secondary spark plug cable must also be checked. Replace cable if it has been burned or damaged. Arcing at the tower will carbonize the cable boot, which if it is connected to a new ignition coil, will cause the coil to fail. If the secondary coil cable shows any signs of damage, it should be replaced with a new cable and new terminal. Carbon tracking on the old cable can cause arcing and the failure of a new ignition coil. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Specifications > Page 2862 Ignition Coil: Service and Repair IGNITION COIL The ignition coil is an epoxy filled type.

The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Refer to Camshaft Position Sensor, Ignition System for more information. CAMSHAFT POSITION SENSOR The camshaft position sensor is located in the distributor on all engines. The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal 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. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Locations > Page 2869 Camshaft Position Sensor: Service and Repair CAMSHAFT POSITION SENSOR Camshaft Position Sensor The camshaft position sensor is located in the distributor.

Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in which they were removed from the engine. A single plug displaying an abnormal condition indicates that a problem exists in the corresponding cylinder. Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or oil fouled. Refer to the Spark Plug Condition. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Specifications > Page 2890 Spark Plug: Testing and Inspection SPARK PLUG CONDITIONS Normal Operation and Cold (Carbon) Fouling Normal Operating The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is evident with most grades of commercial gasoline. There will not be evidence of electrode burning. Gap growth will not average more than approximately 0.025 mm (0.001 in) per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the electrodes filed, have the gap set and then be installed. Some fuel refiners in several areas of the United States have introduced a manganese additive (MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits. Normal Operation and Cold (Carbon) Fouling Cold Fouling/Carbon Fouling Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be caused by a clogged air cleaner element or repeated short operating times (short trips). Wet Fouling or Gas Fouling A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the fouled plugs. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Specifications > Page 2891 Oil or Ash Encrusted Oil or Ash Encrusted If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of oil entry into that particular combustion chamber. Electrode Gap Bridging Electrode Gap Bridging Electrode gap bridging may be traced to loose deposits in the combustion chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be cleaned using standard procedures. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Specifications > Page 2892 Scavenger Deposits Scavenger Deposits Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is a normal condition caused by chemical additives in certain fuels. These additives are designed to change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in condition and can be cleaned using standard procedures. Chipped Electrode Insulator Chipped Electrode Insulator A chipped electrode insulator usually results from bending the center electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation can also separate the insulator from the center electrode. Spark plugs with this condition must be replaced. Preignition Damage Pre-ignition Damage Preignition damage is usually caused by excessive combustion chamber temperature. The center electrode dissolves first and the ground electrode Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Specifications > Page 2893 dissolves somewhat latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine. Determine if ignition timing is over advanced or if other operating conditions are causing engine overheating. (The heat range rating refers to the operating temperature of a particular type spark plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon the thickness and length of the center electrodes porcelain insulator.) Spark Plug Overheating Spark Plug Overheating Overheating is indicated by a white or gray center electrode insulator that also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug overheating. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Specifications > Page 2894 Spark Plug: Service and Repair Heat Shields Spark plug cable beat shields are pressed into the cylinder head to surround each cable boot and spark plug. If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides of shield for removal. Each shield is slotted to allow for compression and removal. To install the shields, align shield to machined opening in cylinder head and tap into place with a block of wood. PLUG REMOVAL 1. Remove engine cover. Cable Removal 2. Always remove spark plug or ignition coil cables by grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady motion. Never pull directly on the cable. Internal damage to cable will result. 3. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area around the spark plug. This will help prevent foreign material from entering the combustion chamber. 4. Remove the spark plug using a quality socket with a rubber or foam insert. 5. Inspect the spark plug condition. Refer to Spark Plug Condition. PLUG CLEANING The plugs may be cleaned using commercially available spark plug cleaning equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before adjusting gap. CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will remain on the spark plug insulator and will cause plug misfire. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Specifications > Page 2895 PLUG GAP ADJUSTMENT Setting Spark Plug Gap-Typical Check the spark plug gap with a gap gauge tool. If the gap is not correct, adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center electrode. SPARK PLUG GAP 1.01 mm (0.040 in). PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged. Always tighten spark plugs to the specified torque.. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator. When replacing the spark plug and ignition coil cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground. 1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark plugs to 35-41 Nm (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Pressure Regulating Solenoid, A/T > Component Information > Technical Service Bulletins > Customer Interest for Pressure Regulating Solenoid: > 21-08-99 > Apr > 99 > A/T - Buzz/Whining in Reverse When Cold Pressure Regulating Solenoid: Customer Interest A/T - Buzz/Whining in Reverse When Cold NUMBER: 21-08-99 GROUP: Transmission DATE: April 30, 1999 SUBJECT: "Buzz", "Whining", Or "Moaning" Like Noise From A Cold Transmission When Reverse Is Selected. OVERVIEW: This bulletin involves replacing the transmission regulator valve. MODELS: 1996 - 1999 (AB) Ram Van 1996 - 1999 (AN) Dakota 1996 - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango 1996 - 1999 (TJ) Wrangler 1996 - 1999 (XJ) Cherokee 1996 - 1998 (ZJ) Grand Cherokee 1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to normal operating temperature (180 - 210 degrees F). 5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

OVERVIEW: This bulletin involves replacing the transmission regulator valve. MODELS: 1996 - 1999 (AB) Ram Van 1996 - 1999 (AN) Dakota 1996 - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango 1996 - 1999 (TJ) Wrangler 1996 - 1999 (XJ) Cherokee 1996 - 1998 (ZJ) Grand Cherokee 1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to normal operating temperature (180 - 210 degrees F). 5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

The Powertrain Control Module (PCM) will deter- mine when to engage and disengage the solenoid by monitoring vehicle miles per hour (mph) versus the output voltage of the throttle position sensor. Also needed are various inputs from: - Transmission temperature sensor - Output shaft speed sensor - Module timer - Engine rpm - MAP sensor - Brake switch MANUAL TRANSMISSION If equipped with a manual transmission, this PCM output will control operation of the shift indicator lamp (if equipped with lamp). The lamp is controlled by the Powertrain Control Module (PCM). The lamp illuminates on the instrument panel to indicate when the driver should shift to the next highest gear for best fuel economy. The PCM will turn the lamp OFF after 3 to 5 seconds if the shift of gears is not performed. The lamp will remain off until vehicle stops accelerating and is brought back to range of up-shift lamp operation. This will also happen if vehicle is shifted into fifth gear. The indicator lamp is normally illuminated when the ignition switch is turned on and it is turned off when the engine is started up. With the engine running, the lamp is turned ON/OFF depending upon engine speed and load. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Overdrive Indicator Lamp > Component Information > Description and Operation Overdrive Indicator Lamp: Description and Operation OVERDRIVE LAMP - PCM OUTPUT This circuit controls a signal for the operation of the push-button overdrive lamp switch.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

The temperature readings are used to control engagement of the fourth gear overdrive clutch, the converter clutch, and governor pressure. Normal resistance value for the thermistor at room temperature is approximately 1000 ohms. The PCM prevents engagement of the converter clutch and overdrive clutch, when fluid temperature is below approximately 10 °C (50 °F). If fluid temperature exceeds 126 °C (260 °F), the PCM causes a 4-3 downshift and engage the converter clutch. Engagement is according to the third gear converter clutch engagement schedule. The overdrive OFF lamp in the instrument panel illuminates when the shift back to third occurs.

DISCUSSION: Some states that require I/M inspections are beginning to include OBD II "CARB" Readiness as a prerequisite to an I/M test. OBD Readiness tells an I/M station if the OBD II systems have run their self test. Owners, in those states that use OBD Readiness, may be denied an I/M test if one or more of the Readiness monitors read "NO" or in other words the OBD II monitors have not run their tests. It is important to understand that the MIL will not be illuminated because OBD Readiness reads "NO". MIL illumination happens when an actual malfunction or failure of a monitored emissions system occurs. It is possible to have MIL illumination for a detected failure while at the same time having a "NO" for an OBO Readiness monitor. NOTE: MIL ILLUMINATION INDICATES ADDITIONAL PROBLEMS WITH THE VEHICLE. FURTHER DIAGNOSIS AND REPAIR WILL BE REQUIRED BEFORE PROCEEDING FURTHER WITH THIS BULLETIN. OBD Readiness that reads "NO" can be caused by the following: PCM reprogramming, PCM replacement, fault code erasure, battery disconnects and/or replacement. If any of the above items occur before an I/M test, a good chance exists that one or more of the monitors will read "NO" for OBD Readiness. Some customers may be directed back to their dealers for assistance when an I/M test station has not allowed an I/M test due to Readiness status. The following procedures will help technicians efficiently run the Readiness tests so an owner can have their I/M test completed.

FAILURE CODE: XX - Service Adjustment Repair Procedure This bulletin involves operating the vehicle under specific parameters to run or complete the OBD monitors. The number of monitors applicable to a vehicle will vary by type of vehicle and emissions application. In addition, the parameters to run each monitor will vary. Preliminary Checks 1. Perform a MIL bulb check by switching the ignition key "ON" (engine off). The MIL will illuminate as a bulb check. If the MIL does not illuminate, repair the bulb or bulb circuit. 2. Connect a DRB III(R) to the vehicle. Select DRB III(R) standalone, current model year diagnostics, engine, DTC's and related functions, read DTC's. 3. Verity that no emission related DTC's are present and that the MIL is not illuminated with the engine running. NOTE: EMISSION RELATED DTC'S AND MIL ILLUMINATION MAY PREVENT OTHER OBD MONITORS FROM RUNNING. DTC'S THAT ILLUMINATE THE MIL MUST BE REPAIRED BEFORE ATTEMPTING TO RUN THE MONITORS. OBD "CARB" Readiness Check 1. With the DRB III(R) select engine, OBD II monitors, CARB Readiness Status. 2. Read the monitor status. "YES" tells you that monitor has run and is ready for an I/M test, "NO" tells you that the monitor must be run. If all monitors listed read "YES", the vehicle can be returned to the customer for completion of their I/M test. Only monitors that read "NO" must be run to read "YES". NOTE: THE MONITORS LISTED IN THE OBD "CARB" READINESS SCREEN ARE THE ONLY ONES APPLICABLE FOR THE VEHICLE BEING WORKED ON. The vehicle must be operated in various conditions (speed, temperature, etc.) for the monitors to run. Each monitor includes a pre-test and monitor test that can be viewed on the DRB III(R). The pre-test/monitor test screen lists all the preliminary parameters that must be met along with the running parameters for that specific monitor to run. An example of one screen is shown in Figure 1. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > Customer Interest: > 25-02-98 > Oct > 98 > I/M Testing - OBDII CARB Readiness Monitor Information > Page 3018 NOTE: 1997 AND PREVIOUS MODEL VEHICLES WILL HAVE A DIFFERENT LOOKING SCREEN. PRESS THE F1 KEY TO OBTAIN MONITOR RUN CONDITIONS. THE WAY IN WHICH THE MONITORS RUN WILL BE SIMILAR. The following explains how to interpret each section of the screen: PRE-TEST REQUIREMENTS The pre-test requirements include all the operating parameters that must be met before the actual test can run. The vehicle must be operated until each item within the pre-test section are fulfilled. LOW VALUE/HIGH VALUE/BAR GRAPH The low value/high value provides the minimum and maximum operating conditions for each item (ie ECT Range must be between 170° and 260° F in Figure 1). The bar graph will begin to fill when the lowest value required for each item is met. This provides a visual indication that the parameters are being met. The vehicle should be driven until most of each pre-test bar graph is filled. MONITOR REQUIREMENTS Once all pre-test requirements are met, the vehicle must be brought within the parameters listed in the monitor requirements section for the monitors to begin running. As the monitor begins to run, the DRB III(R) will begin to beep. This is an audible indication that the test is in progress. If vehicle operation falls outside any of the parameters, the beeping will stop. If this occurs, the technician must determine if the pre-test requirements or the monitor requirements have fallen outside the window for the test and the vehicle must be driven accordingly for the test to restart. When the monitor completes its test, the DRB III(R) will beep 3 consecutive times. NOTE: THE PURGE FLOW PRE-TEST SCREEN WILL LOOK DIFFERENT THAN THE REST OF THE PRE-TEST/MONITOR SCREENS. PRESS THE F1 KEY ON THE DRB III(R) TO SEE A SIMILAR SCREEN FOR THIS MONITOR. MONITOR RUN PROCESS The following will provide the most efficient order along with tips to help run through the monitor tests quickly. The monitors listed include all possible monitors for either Front Wheel Drive or Rear Wheel Drive vehicles. The vehicle being worked on may have fewer monitors than the maximum available. Only those listed on the DRB III(R) are applicable for the vehicle being worked on. The only monitors that will require attention are those that read "NO" under the OBD "CARB" Readiness Status screen. Front Wheel Drive 1. Evaporative Leak Detection Monitor - This test will require a cold start (possibly an overnight soak either indoors or out depending on conditions). The ambient (outside) temperature must be between 4° and 32° C (40° and 90° F) with the engine coolant temperature within 6° C (10 ° F) of ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen on the DRB III(R) to determine the remaining requirements. 2. Catalyst Monitor - The vehicle must be driven at highway speeds for the time listed in the pre-test screen. If the vehicle is equipped with a manual transaxle, use fourth gear to help meet the requirements. 3. EGR Monitor - It is necessary to maintain TPS, MAP, and RPM ranges listed in the pre-test screen for this test to complete. 4. O2 Sensor Monitor - The vehicle must be driven and brought to a stop for the time listed in the pre-test screen. Automatic transaxle vehicles must be left in drive during the stop period. 5. Purge Monitor - To see a similar screen format as listed in Figure 1, press the F1 key on the DRB III(R) while in the Purge Flow Pre-Test screen. The purge free (PF) cells must update and the monitor will attempt to run on every other throttle closure. Automatic transaxle vehicles must be left in drive for the test to run. If all parameters are met and the test still will not run, place your foot on the brake, open the throttle to 1/4 and then quickly close the throttle. This should allow the PF cells to update. 6. O2 Sensor Heater Monitor - The open throttle time for the O2 Heater pre-test must be exceeded. This monitor will run after the ignition key is switched "Off". After the DRB III(R) switches to No Response (approximately 3 minutes) turn the ignition key "On" and check the O2 Sensor Heater monitor status. It should have switched to "YES". All other monitors should be completed before running this test. Rear Wheel Drive 1. O2 Sensor Heater Monitor - This test will require a cold start (possibly an overnight soak either indoors or outdoors depending on conditions). The ambient (outside) temperature must be between 18° and 38° C (0° and 100° F with the engine coolant temperature within 6° C (10° F) of ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen on the DRB III(R) to determine the remaining Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > Customer Interest: > 25-02-98 > Oct > 98 > I/M Testing - OBDII CARB Readiness Monitor Information > Page 3019 requirements. 2.

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 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3026 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3027 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3028 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.

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. POLICY: Information Only Disclaimer: This bulletin is supplied as technical information only and is not an authorization for repair. 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 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3030 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). Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3031 ^ 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3032 ^ 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3033 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3034 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3035 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3036 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 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3037 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.

CUMMINS Types: ^ CM551 and CM84x series NOTE: Cummins flash reprogrammable PCMs are used on 1998.5 and newer Dodge Trucks. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. Model Year 2000 and earlier vehicles have one Engine 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 Specifics: 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: Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3039 ^ 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. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. 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.

MODELS: 1999 (AB) Ram Van 1999 (AN) Dakota 1999 (BR/BE) Ram Truck 1999 (DN) Durango 1999 (TJ) Wrangler 1999 (XJ) Cherokee 1999 (WJ) Grand Cherokee SYMPTOM/CONDITION: A Powertrain Control Module (PCM) software condition exists that can cause an erroneous engine miss to occur only when in certain screens of the Diagnostic Scan Tool (DRB III). The miss will not set a Malfunction Indicator Lamp (MIL), but may be felt and can be seen while performing diagnostics with the DRB III. This condition occurs only when using the DRB III to read Diagnostic Trouble Codes (DTC's), Secondary Indicators, or 1 Trip Failures and while driving the vehicle. This is more likely to occur during hard acceleration. While in these screens, a miss may be felt by the technician, or when in the Secondary Indicators or 1 Trip Failures screen an erroneous injector circuit failure can flash on the DRB III screen with an accompany beep from the DRB III. This condition may lead technicians to incorrectly diagnose a problem and may cause erroneous repairs that will not fix the vehicle. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the DRB III with the appropriate Diagnostic Procedures Manual, verify all engine/transmission systems are functioning as designed. If DTC's are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptoms have been experienced, perform the Repair Procedure. NOTE: WHENEVER A POWERTRAIN CONTROL MODULE (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION LEVEL.

DISCUSSION: Some states that require I/M inspections are beginning to include OBD II "CARB" Readiness as a prerequisite to an I/M test. OBD Readiness tells an I/M station if the OBD II systems have run their self test. Owners, in those states that use OBD Readiness, may be denied an I/M test if one or more of the Readiness monitors read "NO" or in other words the OBD II monitors have not run their tests. It is important to understand that the MIL will not be illuminated because OBD Readiness reads "NO". MIL illumination happens when an actual malfunction or failure of a monitored emissions system occurs. It is possible to have MIL illumination for a detected failure while at the same time having a "NO" for an OBO Readiness monitor. NOTE: MIL ILLUMINATION INDICATES ADDITIONAL PROBLEMS WITH THE VEHICLE. FURTHER DIAGNOSIS AND REPAIR WILL BE REQUIRED BEFORE PROCEEDING FURTHER WITH THIS BULLETIN. OBD Readiness that reads "NO" can be caused by the following: PCM reprogramming, PCM replacement, fault code erasure, battery disconnects and/or replacement. If any of the above items occur before an I/M test, a good chance exists that one or more of the monitors will read "NO" for OBD Readiness. Some customers may be directed back to their dealers for assistance when an I/M test station has not allowed an I/M test due to Readiness status.

FAILURE CODE: XX - Service Adjustment Repair Procedure This bulletin involves operating the vehicle under specific parameters to run or complete the OBD monitors. The number of monitors applicable to a vehicle will vary by type of vehicle and emissions application. In addition, the parameters to run each monitor will vary. Preliminary Checks 1. Perform a MIL bulb check by switching the ignition key "ON" (engine off). The MIL will illuminate as a bulb check. If the MIL does not illuminate, repair the bulb or bulb circuit. 2. Connect a DRB III(R) to the vehicle. Select DRB III(R) standalone, current model year diagnostics, engine, DTC's and related functions, read DTC's. 3. Verity that no emission related DTC's are present and that the MIL is not illuminated with the engine running. NOTE: EMISSION RELATED DTC'S AND MIL ILLUMINATION MAY PREVENT OTHER OBD MONITORS FROM RUNNING. DTC'S THAT ILLUMINATE THE MIL MUST BE REPAIRED BEFORE ATTEMPTING TO RUN THE MONITORS. OBD "CARB" Readiness Check 1. With the DRB III(R) select engine, OBD II monitors, CARB Readiness Status. 2. Read the monitor status. "YES" tells you that monitor has run and is ready for an I/M test, "NO" tells you that the monitor must be run. If all monitors listed read "YES", the vehicle can be returned to the customer for completion of their I/M test. Only monitors that read "NO" must be run to read "YES". NOTE: THE MONITORS LISTED IN THE OBD "CARB" READINESS SCREEN ARE THE ONLY ONES APPLICABLE FOR THE VEHICLE BEING WORKED ON. The vehicle must be operated in various conditions (speed, temperature, etc.) for the monitors to run. Each monitor includes a pre-test and monitor test that can be viewed on the DRB III(R). The pre-test/monitor test screen lists all the preliminary parameters that must be met along with the running parameters for that specific monitor to run. An example of one screen is shown in Figure 1. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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: > 25-02-98 > Oct > 98 > I/M Testing - OBDII CARB Readiness Monitor Information > Page 3083 NOTE: 1997 AND PREVIOUS MODEL VEHICLES WILL HAVE A DIFFERENT LOOKING SCREEN. PRESS THE F1 KEY TO OBTAIN MONITOR RUN CONDITIONS. THE WAY IN WHICH THE MONITORS RUN WILL BE SIMILAR. The following explains how to interpret each section of the screen: PRE-TEST REQUIREMENTS The pre-test requirements include all the operating parameters that must be met before the actual test can run. The vehicle must be operated until each item within the pre-test section are fulfilled. LOW VALUE/HIGH VALUE/BAR GRAPH The low value/high value provides the minimum and maximum operating conditions for each item (ie ECT Range must be between 170° and 260° F in Figure 1). The bar graph will begin to fill when the lowest value required for each item is met. This provides a visual indication that the parameters are being met. The vehicle should be driven until most of each pre-test bar graph is filled. MONITOR REQUIREMENTS Once all pre-test requirements are met, the vehicle must be brought within the parameters listed in the monitor requirements section for the monitors to begin running. As the monitor begins to run, the DRB III(R) will begin to beep. This is an audible indication that the test is in progress. If vehicle operation falls outside any of the parameters, the beeping will stop. If this occurs, the technician must determine if the pre-test requirements or the monitor requirements have fallen outside the window for the test and the vehicle must be driven accordingly for the test to restart. When the monitor completes its test, the DRB III(R) will beep 3 consecutive times. NOTE: THE PURGE FLOW PRE-TEST SCREEN WILL LOOK DIFFERENT THAN THE REST OF THE PRE-TEST/MONITOR SCREENS. PRESS THE F1 KEY ON THE DRB III(R) TO SEE A SIMILAR SCREEN FOR THIS MONITOR. MONITOR RUN PROCESS The following will provide the most efficient order along with tips to help run through the monitor tests quickly. The monitors listed include all possible monitors for either Front Wheel Drive or Rear Wheel Drive vehicles. The vehicle being worked on may have fewer monitors than the maximum available. Only those listed on the DRB III(R) are applicable for the vehicle being worked on. The only monitors that will require attention are those that read "NO" under the OBD "CARB" Readiness Status screen. Front Wheel Drive 1. Evaporative Leak Detection Monitor - This test will require a cold start (possibly an overnight soak either indoors or out depending on conditions). The ambient (outside) temperature must be between 4° and 32° C (40° and 90° F) with the engine coolant temperature within 6° C (10 ° F) of ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen on the DRB III(R) to determine the remaining requirements. 2. Catalyst Monitor - The vehicle must be driven at highway speeds for the time listed in the pre-test screen. If the vehicle is equipped with a manual transaxle, use fourth gear to help meet the requirements. 3. EGR Monitor - It is necessary to maintain TPS, MAP, and RPM ranges listed in the pre-test screen for this test to complete. 4. O2 Sensor Monitor - The vehicle must be driven and brought to a stop for the time listed in the pre-test screen. Automatic transaxle vehicles must be left in drive during the stop period. 5. Purge Monitor - To see a similar screen format as listed in Figure 1, press the F1 key on the DRB III(R) while in the Purge Flow Pre-Test screen. The purge free (PF) cells must update and the monitor will attempt to run on every other throttle closure. Automatic transaxle vehicles must be left in drive for the test to run. If all parameters are met and the test still will not run, place your foot on the brake, open the throttle to 1/4 and then quickly close the throttle. This should allow the PF cells to update. 6. O2 Sensor Heater Monitor - The open throttle time for the O2 Heater pre-test must be exceeded. This monitor will run after the ignition key is switched "Off". After the DRB III(R) switches to No Response (approximately 3 minutes) turn the ignition key "On" and check the O2 Sensor Heater monitor status. It should have switched to "YES". All other monitors should be completed before running this test. Rear Wheel Drive 1. O2 Sensor Heater Monitor - This test will require a cold start (possibly an overnight soak either indoors or outdoors depending on conditions). The ambient (outside) temperature must be between 18° and 38° C (0° and 100° F with the engine coolant temperature within 6° C (10° F) of ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen on the DRB III(R) to determine the remaining Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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: > 25-02-98 > Oct > 98 > I/M Testing - OBDII CARB Readiness Monitor Information > Page 3084 requirements. 2. Evaporative Leak Detection Monitor - This test will require a cold start (possibly an overnight soak either indoors or outdoors depending on conditions).

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 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3091 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3092 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3093 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.

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. POLICY: Information Only Disclaimer: This bulletin is supplied as technical information only and is not an authorization for repair. 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 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3095 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). Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3096 ^ 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3097 ^ 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3098 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3099 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3100 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3101 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 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3102 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.

CUMMINS Types: ^ CM551 and CM84x series NOTE: Cummins flash reprogrammable PCMs are used on 1998.5 and newer Dodge Trucks. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. Model Year 2000 and earlier vehicles have one Engine 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 Specifics: 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: Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) 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 3104 ^ 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. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. 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.

OVERVIEW: This bulletin involves replacing the transmission regulator valve. MODELS: 1996 - 1999 (AB) Ram Van 1996 - 1999 (AN) Dakota 1996 - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango 1996 - 1999 (TJ) Wrangler 1996 - 1999 (XJ) Cherokee 1996 - 1998 (ZJ) Grand Cherokee 1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to normal operating temperature (180 - 210 degrees F). 5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

MODELS: 1996 - 1999 (AB) Ram Van 1996 - 1999 (AN) Dakota 1996 - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango 1996 - 1999 (TJ) Wrangler 1996 - 1999 (XJ) Cherokee 1996 - 1998 (ZJ) Grand Cherokee 1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to normal operating temperature (180 - 210 degrees F). 5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

The Powertrain Control Module (PCM) will deter- mine when to engage and disengage the solenoid by monitoring vehicle miles per hour (mph) versus the output voltage of the throttle position sensor. Also needed are various inputs from: - Transmission temperature sensor - Output shaft speed sensor - Module timer - Engine rpm - MAP sensor - Brake switch MANUAL TRANSMISSION If equipped with a manual transmission, this PCM output will control operation of the shift indicator lamp (if equipped with lamp). The lamp is controlled by the Powertrain Control Module (PCM). The lamp illuminates on the instrument panel to indicate when the driver should shift to the next highest gear for best fuel economy. The PCM will turn the lamp OFF after 3 to 5 seconds if the shift of gears is not performed. The lamp will remain off until vehicle stops accelerating and is brought back to range of up-shift lamp operation. This will also happen if vehicle is shifted into fifth gear. The indicator lamp is normally illuminated when the ignition switch is turned on and it is turned off when the engine is started up. With the engine running, the lamp is turned ON/OFF depending upon engine speed and load. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Actuators and Solenoids A/T > Pressure Regulating Solenoid, A/T > Component Information > Technical Service Bulletins > Customer Interest for Pressure Regulating Solenoid: > 21-08-99 > Apr > 99 > A/T - Buzz/Whining in Reverse When Cold Pressure Regulating Solenoid: Customer Interest A/T - Buzz/Whining in Reverse When Cold NUMBER: 21-08-99 GROUP: Transmission DATE: April 30, 1999 SUBJECT: "Buzz", "Whining", Or "Moaning" Like Noise From A Cold Transmission When Reverse Is Selected.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Fluid - A/T > Component Information > Technical Service Bulletins > A/T - ATF+4 Fluid Usage/Applications > Page 3217 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.

It is an electro-hydraulic device located in the governor body on the valve body transfer plate (Fig. 3). The inlet side of the solenoid valve is exposed to normal transmission line pressure. The outlet side of the valve leads to the valve body governor circuit. The solenoid valve regulates line pressure to produce governor pressure. The average current supplied to the solenoid controls governor pressure. One amp current produces zero kPa/psi governor pressure. Zero amps sets the maximum governor pressure. The PCM turns on the bans control relay which supplies electrical power to the solenoid valve. Operating voltage is 12 volts (DC). The PCM controls the ground side of the solenoid using the governor pressure solenoid control circuit. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T > Component Information > Description and Operation > Governor Pressure Solenoid Valve > Page 3245 Governor: Description and Operation Governor Pressure Sensor Fig. 4 The governor pressure sensor measures output pressure of the governor pressure solenoid valve (Fig. 4). The sensor output signal provides the necessary feedback to the PCM. This feedback is needed to adequately control governor pressure. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T > Component Information > Description and Operation > Governor Pressure Solenoid Valve > Page 3246 Governor: Description and Operation Governor Body and Transfer Plate Fig. 4 The transfer plate is designed to supply transmission line pressure to the governor pressure solenoid valve and to return governor pressure. The governor pressure solenoid valve is mounted in the governor body. The body is bolted to the lower side of the transfer plate (Fig. 4). The transfer plate channels line pressure to the solenoid valve through the governor body. It also channels governor pressure from the solenoid valve to the governor circuit. It is the solenoid valve that develops the necessary governor pressure. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T > Component Information > Description and Operation > Governor Pressure Solenoid Valve > Page 3247 Governor: Description and Operation Governor Pressure Curves There are four governor pressure curves programmed into the transmission control module. The different curves allow the control module to adjust governor pressure for varying conditions. One curve is used for operation when fluid temperature is at, or below, 1°C (30°F). A second curve is used when fluid temperature is at, or above, 10°C (50°F) during normal city or highway driving. A third curve is used during wide-open throttle operation. The fourth curve is used when driving with the transfer case in low range. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T > Component Information > Service and Repair > Replacement Governor: Service and Repair Replacement REMOVAL 1.

The valve temporarily bypasses the clutch piston feed orifice at the start of a 3-4 upshift. This exposes a larger passage into the piston retainer resulting in a much faster clutch fill and apply sequence. The quick fill valve does not bypass the regular clutch feed orifice throughout the 3-4 upshift. Instead, once a predetermined pressure develops within the clutch, the valve closes the bypass. Clutch fill is then completed through the regular feed orifice. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Overdrive Assembly, A/T > Component Information > Description and Operation > Quick Fill Valve > Page 3275 Overdrive Assembly: Description and Operation 3-4 Shift Sequence The overdrive clutch is applied in fourth gear only. The direct clutch is applied in all ranges except fourth gear. Fourth gear overdrive range is electronically controlled and hydraulically activated. Various sensor inputs are supplied to the Powertrain Control Module (PCM) to operate the overdrive solenoid on the valve body. The solenoid contains a check ball that opens and closes a vent port in the 3-4 shift valve feed passage. The overdrive solenoid (and check ball) are not energized in first, second, third, or reverse gear. The vent port remains open, diverting line pressure from the 2-3 shift valve away from the 3-4 shift valve. The overdrive control switch must be in the ON position to transmit overdrive status to the PCM. A 3-4 upshift occurs only when the overdrive solenoid is energized by the PCM. The PCM energizes the overdrive solenoid during the 3-4 upshift. This causes the solenoid check ball to close the vent port allowing line pressure from the 2-3 shift valve to act directly on the 3-4 upshift valve. Line pressure on the 3-4 shift valve overcomes valve spring pressure moving the valve to the upshift position. This action exposes the feed passages to the 3-4 timing valve, 3-4 quick fill valve, 3-4 accumulator, and ultimately to the overdrive piston. Line pressure through the timing valve moves the overdrive piston into contact with the overdrive clutch. The direct clutch is disengaged before the overdrive clutch is engaged. The boost valve provides increased fluid apply pressure to the overdrive clutch during 3-4 upshifts, and when accelerating in fourth gear. The 3-4 accumulator cushions overdrive clutch engagement to smooth 3-4 upshifts. The accumulator is charged at the same time as apply pressure acts against the overdrive piston. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Overdrive Assembly, A/T > Component Information > Service and Repair > Assembly Overdrive Assembly: Service and Repair Assembly REMOVAL 1. Shift transmission into Park. 2. Raise vehicle. 3. Mark propeller shaft universal joint(s) and axle pinion yoke for alignment reference at installation. 4. Disconnect and remove propeller shaft(s). 5. Remove transmission oil pan, remove gasket, drain oil and reinstall pan. 6. If overdrive unit had malfunctioned, or if fluid is contaminated, remove entire transmission. If diagnosis indicated overdrive problems only, remove just the overdrive unit. 7. Support transmission with transmission jack. 8. Remove vehicle speed sensor. Fig. 33 9. Remove bolts attaching overdrive unit to transmission (Fig. 33). CAUTION: Support the overdrive unit with a jack before moving it rearward. This is necessary to prevent damaging the intermediate shaft. Do not allow the shaft to support the entire weight of the overdrive unit. 10. Carefully work overdrive unit off intermediate shaft. Do not tilt unit during removal. Keep it as level as possible. 11. If overdrive unit does not require service, immediately insert Alignment Tool 6227-2 in splines of planetary gear and overrunning clutch to prevent splines from rotating out of alignment. If misalignment occurs, overdrive unit will have to be disassembled in order to realign splines. 12. Remove and retain overdrive piston thrust bearing. Bearing may remain on piston or in clutch hub during removal. 13. Position drain pan on workbench. 14. Place overdrive unit over drain pan. Tilt unit to drain residual fluid from case. 15. Examine fluid for clutch material or metal fragments. If fluid contains these items, overhaul will be necessary. 16. If overdrive unit does not require any service, leave alignment tool in position. Tool will prevent accidental misalignment of planetary gear and overrunning clutch splines. INSTALLATION 1. Be sure overdrive unit Alignment Tool 6227-2 is fully seated before moving unit. If tool is not seated and gear splines rotate out of alignment, overdrive unit will have to be disassembled in order to realign splines. 2. If overdrive piston retainer was not removed during service and original case gasket is no longer reusable, prepare new gasket by trimming it. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Overdrive Assembly, A/T > Component Information > Service and Repair > Assembly > Page 3278 Fig. 34 3. Cut out old case gasket around piston retainer with razor knife (Fig. 34). 4. Use old gasket as template and trim new gasket to fit. 5. Position new gasket over piston retainer and on transmission case. Use petroleum jelly to hold gasket in place if necessary. Do not use any type of sealer to secure gasket. Use petroleum jelly only. Fig. 35 6. Install selective spacer on intermediate shaft, if removed. Spacer goes in groove just rearward of shaft rear splines (Fig. 35). 7. Install thrust bearing in overdrive unit sliding hub. Use petroleum jelly to hold bearing in position. CAUTION: Be sure the shoulder on the inside diameter of the bearing is facing forward. 8. Verify that splines in overdrive planetary gear and overrunning clutch hub are aligned with Alignment Tool 6227-2. Overdrive unit cannot be installed if splines are not aligned. If splines have rotated out of alignment, unit will have to be disassembled to realign splines. 9. Carefully slide Alignment Tool 6227-2 out of overdrive planetary gear and overrunning clutch splines. 10. Raise overdrive unit and carefully slide it straight onto intermediate shaft. Insert park rod into park lock reaction plug at same time. Avoid tilting overdrive during installation as this could cause planetary gear and overrunning clutch splines to rotate out of alignment. If this occurs, it will be necessary to remove and disassemble overdrive unit to realign splines. 11. Work overdrive unit forward on intermediate shaft until seated against transmission case. 12. Install bolts attaching overdrive unit to transmission unit. Tighten bolts in diagonal pattern to 34 Nm (25 ft. lbs.). 13. Install speed sensor. 14. Connect speed sensor and overdrive wires. 15.

SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure. NOTE: WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION LEVEL.

Signals from this sensor are shared with the PCM. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Sensors and Switches A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Locations Transmission Temperature Sensor/Switch: Locations Governor Pressure Sensor, Transmission Temperature Sensor, Governor Pressure Solenoid, Governor The transmission temperature sensor is located in the transmission solenoid assembly in the valve body. The governor pressure sender and the transmission fluid temperature thermistor are separate sensors in the same component. This component is attached to the governor body in the solenoid assembly of the valve body. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Sensors and Switches A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - Description and Operation Transmission fluid temperature readings are supplied to the transmission control module by the thermistor. The temperature readings are used to control engagement of the fourth gear overdrive clutch, the converter clutch, and governor pressure. Normal resistance value for the thermistor at room temperature is approximately 1000 ohms. The PCM prevents engagement of the converter clutch and overdrive clutch, when fluid temperature is below approximately 10 °C (50 °F). If fluid temperature exceeds 126 °C (260 °F), the PCM causes a 4-3 downshift and engage the converter clutch. Engagement is according to the third gear converter clutch engagement schedule. The overdrive OFF lamp in the instrument panel illuminates when the shift back to third occurs. The transmission will not allow fourth gear operation until fluid temperature decreases to approximately 110 °C (230 °F). The thermistor is part of the governor pressure sensor assembly and is immersed in transmission fluid at all times. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Sensors and Switches A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation > Page 3351 Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - PCM Input TRANSMISSION TEMPERATURE SENSOR - PCM INPUT This input is used in the shift operation for speed electronic transmissions only.

Brackets support and secure the cable at each end and clips are used to secure the cable to the floor pan (Fig. 255) and (Fig. 256). The cable is operated by an arm on the steering column shaft. The cable has a built-in adjuster mechanism at the transmission end (Fig. 256). The mechanism consists of an internal clamp and release button that allows the cable to be extended, or shortened for adjustment. SHIFT CABLE ADJUSTMENT CHECK The ignition key should rotate from Off to Lock only when the shift lever is in Park. Shifting out of Park should only be possible when the ignition key is in Off, Run, or Start positions. It should not be possible when the key is in Accessory or Lock position. Engine start should only occur in Park and Neutral position. SHIFT CABLE ADJUSTMENT PROCEDURE 1. Place column shift lever in Park. 2. Raise vehicle. 3. Unsnap cable from transmission shift lever (Fig. 256). 4. Move transmission shift lever all the way rearward to Park detent. 5. Release cable adjuster (at transmission end of cable) to unlock cable. 6. Snap cable back onto pin on transmission shift lever. 7. Press cable lock inward to secure cable. 8.

The throttle lever is actuated by a cable connected to the engine throttle body lever (Fig. 254). A retaining clip at the engine-end of the cable is removed to provide for cable adjustment. The retaining clip is then installed back onto the throttle valve cable to lock in the adjustment. A correctly adjusted throttle valve cable will cause the throttle lever on the transmission to move simultaneously with the throttle body lever from the idle position. Proper adjustment allows simultaneous movement without causing the transmission throttle lever to move ahead of, or lag behind the throttle body lever. THROTTLE VALVE CABLE ADJUSTMENT CHECK 1. Turn ignition key to OFF position. 2. Remove air cleaner. 3. Slide cable off attachment stud on throttle body lever (Fig. 254). 4. Verify that throttle body lever is at curb idle position. Then verify that transmission throttle lever is also at idle (full forward) position. 5. Compare position of cable end to attachment stud on throttle body lever: a. Cable end and attachment stud should be aligned (or centered on one another) to within 1 mm (0.039 inch) in either direction. b. If cable end and attachment stud are misaligned (off center), cable will have to be adjusted as described in following procedure. 6. Reconnect cable end to attachment stud. Then with aid of a helper, observe movement of transmission throttle lever and lever on throttle body. a. If both levers move simultaneously from idle to half-throttle and back to idle position, adjustment is correct. b. If transmission throttle lever moves ahead of, or lags behind throttle body lever, cable adjustment will be necessary. Or, if throttle body lever prevents transmission lever from returning to closed position, cable adjustment will be necessary. THROTTLE VALVE CABLE ADJUSTMENT PROCEDURE 1. Turn ignition switch to OFF position and shift into Park. 2. Remove air cleaner. 3. Disconnect cable end from attachment stud on throttle body. Carefully slide cable off stud. Do not pull or pry cable off. 4. Verify that transmission throttle lever is in idle (full forward) position. Then be sure lever on throttle body is at curb idle position. 5. Insert a small screwdriver under edge of retaining clip and remove retaining clip. 6. Center cable end on attachment stud to within 1 mm (0.039 inch). NOTE: Be sure that as the cable is pulled forward and centered on the throttle lever stud, the cable housing moves smoothly with the cable. Due to the angle at which the cable housing enters the spring housing, the cable housing may bind slightly and create an incorrect adjustment. 7. Install retaining clip onto cable housing. 8. Check cable adjustment. Be sure transmission throttle lever and lever on throttle body move simultaneously and as described in cable adjustment checking procedure. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter > Component Information > Specifications Torque Converter: Specifications Bolt, torque convertor 23 ft.lb Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter > Component Information > Specifications > Page 3375 Torque Converter: Service and Repair REMOVAL 1.

Inputs that determine clutch engagement are: coolant temperature, engine rpm, vehicle speed, throttle position, and manifold vacuum. The torque converter clutch is engaged by the clutch solenoid on the valve body. The clutch can be engaged in third and fourth gear ranges depending on overdrive control switch position. If the overdrive control switch is in the normal ON position, the clutch will engage after the shift to fourth gear, and above approximately 72 km/in (45 mph). If the control switch is in the OFF position, the clutch will engage after the shift to third gear, at approximately 56 km/in (35 mph) at light throttle. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Locations > Component Locations O/D (3-4) Solenoid, TCC Solenoid, Governor Pressure Sensor, Governor Pressure Solenoid Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Locations > Component Locations > Page 3387 TCC Solenoid Connector, Park/Neutral Position Switch Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Locations > Page 3388 Torque Converter Clutch Solenoid: Description and Operation TORQUE CONVERTOR CLUTCH (TCC) SOLENOID - PCM OUTPUT This circuit controls operation of the transmission mounted Torque Convertor Clutch (TCC) solenoid used for torque convertor engagement. The Powertrain Control Module (PCM) will deter- mine when to engage and disengage the solenoid by monitoring vehicle miles per hour (mph) versus the output voltage of the throttle position sensor. Also needed are various inputs from: - Transmission temperature sensor - Output shaft speed sensor - Module timer - Engine rpm - MAP sensor - Brake switch MANUAL TRANSMISSION If equipped with a manual transmission, this PCM output will control operation of the shift indicator lamp (if equipped with lamp). The lamp is controlled by the Powertrain Control Module (PCM). The lamp illuminates on the instrument panel to indicate when the driver should shift to the next highest gear for best fuel economy. The PCM will turn the lamp OFF after 3 to 5 seconds if the shift of gears is not performed. The lamp will remain off until vehicle stops accelerating and is brought back to range of up-shift lamp operation. This will also happen if vehicle is shifted into fifth gear. The indicator lamp is normally illuminated when the ignition switch is turned on and it is turned off when the engine is started up. With the engine running, the lamp is turned ON/OFF depending upon engine speed and load. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Control System Relay, A/T > Component Information > Locations 8w-10-2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Control System Relay, A/T > Component Information > Locations > Page 3392 Transmission Control System Relay: Diagrams Power Distribution Center Transmission Control Relay Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Control System Relay, A/T > Component Information > Locations > Page 3393 Transmission Control System Relay: Description and Operation TRANSMISSION RELAY - PCM OUTPUT The output to this relay provides battery voltage to the overdrive (OD), torque converter clutch (TCC) and governor pressure solenoids.

The sensor is positioned over the park gear and monitors transmission output shaft rotating speed. Speed sensor signals are triggered by the park gear lugs as they rotate past the sensor pickup face. Input signals from the sensor are sent to the transmission control module for processing. The vehicle speed sensor also serves as a backup for the transmission speed sensor. Signals from this sensor are shared with the PCM. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Temperature Sensor/Switch, A/T > Component Information > Locations Transmission Temperature Sensor/Switch: Locations Governor Pressure Sensor, Transmission Temperature Sensor, Governor Pressure Solenoid, Governor The transmission temperature sensor is located in the transmission solenoid assembly in the valve body. The governor pressure sender and the transmission fluid temperature thermistor are separate sensors in the same component. This component is attached to the governor body in the solenoid assembly of the valve body. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - Description and Operation Transmission fluid temperature readings are supplied to the transmission control module by the thermistor. The temperature readings are used to control engagement of the fourth gear overdrive clutch, the converter clutch, and governor pressure. Normal resistance value for the thermistor at room temperature is approximately 1000 ohms. The PCM prevents engagement of the converter clutch and overdrive clutch, when fluid temperature is below approximately 10 °C (50 °F). If fluid temperature exceeds 126 °C (260 °F), the PCM causes a 4-3 downshift and engage the converter clutch. Engagement is according to the third gear converter clutch engagement schedule. The overdrive OFF lamp in the instrument panel illuminates when the shift back to third occurs. The transmission will not allow fourth gear operation until fluid temperature decreases to approximately 110 °C (230 °F). The thermistor is part of the governor pressure sensor assembly and is immersed in transmission fluid at all times. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation > Page 3422 Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - PCM Input TRANSMISSION TEMPERATURE SENSOR - PCM INPUT This input is used in the shift operation for speed electronic transmissions only.

The system performs five basic functions which are: pressure supply, pressure regulation, flow control, clutch/band application, and lubrication. PRESSURE REGULATION The pressure regulator valve maintains line pressure. The amount of pressure developed is controlled by throttle pressure which is dependent on the degree of throttle opening. The regulator valve is located in the valve body. The throttle valve determines line pressure and shift speed. Governor pressure increases in proportion to vehicle speed. The throttle valve controls upshift and downshift speeds by regulating pressure according to throttle position. SHIFT VALVE FLOW CONTROL The manual valve is operated by the gearshift linkage and provides the operating range selected by the driver. The 1-2 shift valve provides 1-2 or 2-1 shifts and the 2-3 shift valve provides 2-3 or 3-2 shifts. The kickdown valve provides forced 3-2 or 3-1 downshifts depending on vehicle speed. Downshifts occur when the throttle is opened beyond downshift detent position. Detent is reached just before wide open throttle position. The 2-3 valve throttle pressure plug provides 3-2 downshifts at varying throttle openings depending on vehicle speed. The 1-2 shift control valve transmits 1-2 shift pressure to the accumulator piston. This controls kickdown band capacity on 1-2 upshifts and 3-2 downshifts. The 3-4 shift, quick fill, and timing valves plus the 3-4 accumulator, are only actuated when the overdrive solenoid is energized. The solenoid contains a check ball that controls a vent port to the 3-4 valves. The check ball either diverts line pressure away from or directly to the 3-4 valves. The limit valve determines maximum speed at which a 3-2 part throttle kickdown can be made. On transmissions without a limit valve, maximum speed for a 3-2 kickdown is at detent position. The 2-3 shuttle valve has two functions. The first is fast front band release and smooth engagement during lift-foot 2-3 upshifts. The second is to regulate front clutch and band application during 3-2 downshifts. The 3-4 timing valve is moved by line pressure coming through the 3-4 shift valve. The timing valve holds the 2-3 shift valve in an upshift position. The purpose is to prevent the 2-3 valve from up or downshifting before the 3-4 valve. The 3-4 accumulator is mounted on the overdrive housing and performs the same function as the 2-3 accumulator; it is used to smooth engagement during a 3-4 shift. The switch valve directs fluid apply pressure to the converter clutch in one position and releases it in the opposite position. It also directs oil to the cooling and lube circuits. The switch valve regulates oil pressure to the torque converter by limiting maximum oil pressure to 130 psi. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Description and Operation > Hydraulic Control System > Page 3429 Valve Body: Description and Operation Shift Valve Operation The shift valves are moved by a combination of throttle and governor pressure. The governor pressure is generated by electrical components. The conditions under which a shift to fourth will not occur are: Overdrive switch is Off - Transmission fluid temperature is below 10 °C (50 °F) or above 121 °C (250 °F) - Shift to third not yet completed - Vehicle speed too low for 3-4 shift to occur - Battery temperature below -5 °F. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Description and Operation > Page 3430 Valve Body: Adjustments OVERVIEW There are two control pressure adjustments on the valve body: Line Pressure - Throttle Pressure Line and throttle pressures are interdependent because each affects shift quality and timing. As a result, both adjustments must be performed properly and in the correct sequence. Adjust line pressure first and throttle pressure last. LINE PRESSURE ADJUSTMENT Fig. 260 Measure distance from the valve body to the inner edge of the adjusting screw with an accurate steel scale (Fig. 260). Distance should be 33.4 mm (1-5/16 inch). If adjustment is required, turn the adjusting screw in, or out, to obtain required distance setting. NOTE: The 33.4 mm (1-5/16 inch) setting is an approximate setting. Manufacturing tolerances may make it necessary to vary from this dimension to obtain desired pressure. One complete turn of the adjusting screw changes line pressure approximately 1-2/3 psi (9 kPa). Turning the adjusting screw counterclockwise increases pressure while turning the screw clockwise decreases pressure. THROTTLE PRESSURE ADJUSTMENT Fig. 261 Insert Gauge Tool C-3763 between the throttle lever cam and the kickdown valve stem (Fig. 261). Push the gauge tool inward to compress the kickdown valve against the spring and bottom the throttle valve. Maintain pressure against kickdown valve spring. Turn throttle lever stop screw until the screw head touches throttle lever tang and the throttle lever cam touches gauge tool. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Description and Operation > Page 3431 NOTE: The kickdown valve spring must be fully compressed and the kickdown valve completely bottomed to obtain correct adjustment. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Service and Repair > Removal and Installation Valve Body: Service and Repair Removal and Installation OVERVIEW The valve body can be removed for service without having to remove the transmission assembly.

Do not use gasoline, kerosene, or any type of caustic solution. Do not immerse any of the electrical components in cleaning solution. Clean the governor solenoid and sensor and the dual solenoid and harness assembly 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. Wipe the governor pressure sensor and solenoid valve with dry, lint free shop towels only. The O-rings on the sensor and solenoid valve are the only serviceable components. Be sure the vent ports in the solenoid valve are open and not blocked by dirt or debris. Replace the valve and/or sensor only when DRB scan tool diagnosis indicates this is necessary. Or, if either part has sustained physical damage (dented, deformed, broken, etc.). CAUTION: Do not turn the small screw at the end of the solenoid valve for any reason. Turning the screw in either direction will ruin solenoid calibration and result in solenoid failure. In addition, the filter on the solenoid valve is NOT serviceable. Do not try to remove the filter as this will damage the valve housing. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Service and Repair > Removal and Installation > Page 3476 Fig. 250 Inspect the throttle and manual valve levers and shafts (Fig. 250). Do not attempt to straighten a bent shaft or correct a loose lever. Replace these components if worn, bent, loose or damaged in any way. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Service and Repair > Removal and Installation > Page 3477 CAUTION: Many of the valves and plugs, such as the throttle valve, shuttle valve plug, 1-2 shift valve and 1-2 governor plug, are made of coated aluminum. Aluminum components are identified by the dark color of the special coating applied to the surface (or by testing with a magnet). Do not sand aluminum valves or plugs under any circumstances. This practice could damage the special coating causing the valves/plugs to stick and bind. 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. Check the two separator plates for distortion or damage of any kind. Inspect the upper housing, lower housing, 3-4 accumulator housing, and transfer plate carefully. Be sure all fluid passages are clean and clear. Check condition of the upper housing and transfer plate check balls as well. The check balls and ball seats must not be worn or damaged. Trial fit each valve and plug in its bore to check freedom of operation. When clean and dry, the valves and plugs 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. The only serviceable valve body components are listed below. The remaining valve body components are serviced only as part of a complete valve body assembly. Serviceable parts are: dual solenoid and harness assembly - solenoid gasket - solenoid case connector O-rings and shoulder bolt - switch valve and spring - pressure adjusting screw and bracket assembly - throttle lever - manual lever and shaft seal - throttle lever shaft seal, washer, and E-clip - fluid filter and screws - detent ball and spring - valve body screws - governor pressure solenoid - governor pressure sensor and retaining clip - park lock rod and E-clip Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Service and Repair > Removal and Installation > Page 3478 Valve Body: Service and Repair Assembly Assembly Precaution CAUTION: Do not force valves or plugs into place during reassembly.

DISCUSSION: The axle lubricant used in all corporate axles was changed in formulation starting at the beginning of the 1998 model year. The corporate axles involved include: the 8.25 and 9.25 rear axles, and the C205F front axle. The new lubricant in use is SAE 75W-90 p/n 05010320AA. The lubricant change was made as a fuel economy improvement. The new axle lubricant is more chemically aggressive/reactive when in contact with the previous used Room Temperature Vulcanizable (RTV) sealant. Because of this condition, the RTV used in assembly of the pan/cover to the axle housing was revised and improved. When re-sealing axle covers, using the proper sealing material to minimize any potential sealant breakdown is important. The only recommended sealing material for all corporate axle covers is MOPAR RTV Sealant, p/n 05013477M. This RTV is red/orange in color. NOTE: IF SAE 75W-90 LUBRICANT IS USED TO REFILL ANY CORPORATE AXLE, THEN THE RED/ORANGE MOPAR RTV SEALANT, P/N 05013477AA, SHOULD BE USED TO SEAL THE COVER TO THE AXLE HOUSING. To optimize sealant performance and enhance adhesion, flanges should be clean and free of residual lubricant. The mating flanges should first be cleaned of any excess old RTV using a plastic putty knife. Final cleaning/degreasing shall be done by spraying MOPAR Brake Parts Cleaner, p/n 04549623, on the carrier and cover flanges, followed by a wipe with a clean dry cloth. Care should be taken to avoid spraying the parts cleaner inside the carrier. Once the RTV has been applied, the axle cover is to be installed to the housing within 3 to 5 minutes to prevent skinning over of the RTV. NOTE: IF THE AXLE COVER IS NOT INSTALLED WITHIN THE 3 TO 5 MINUTE TIME FRAME, THE CARRIER COVER FACE MUST BE RECLEANED AND NEW RTV APPLIED, OR ADHESION QUALITY WILL BE COMPROMISED.

DISCUSSION: The customer or servicing technician may notice a milky-like appearance to the 9.25 inch rear axle fluid. This condition may be brought to the customer's attention when the axle fluid is inspected during normal service. Other than the concern for the color of axle fluid, the customer does not experience any other axle complaint. The customer or servicing technician may be concerned because a milky-like appearance to the axle fluid may also indicate the presence of water. The cause of the milky-like appearance to the axle fluid may be due to the use of a white color gear marking compound during the axle assembly process. Axle gear marking compound is used to verify correct ring and pinion gear alignment during manufacture. The 9.25 inch rear axle is assembled on two different assembly lines. To visually distinguish axles from each assembly line, one assembly line used a white color gear marking compound (versus yellow). Half of the axles that were assembled during the above time frame may have the white gear marking compound mixed with the rear axle fluid. The white color gear marking compound is no longer in use by the axle assembly plant. NOTE: IF THE MILKY-LIKE REAR AXLE FLUID APPEARANCE IS DUE TO THE WHITE GEAR MARKING COMPOUND, THEN NO SERVICE ACTION IS NECESSARY TO ADDRESS THIS CONDITION. If the milky-like rear axle fluid appearance is due to the presence of water, then the rear axle will require service. Axle fluid, contaminated with water, may cause rust and damage to the internal components of the axle. Any water in the axle fluid will begin to boil off (reach its gaseous state) before the oil. Placing a small sample of axle fluid on a hot steel surface (around 100C or 212F) will cause any water that may be present in the fluid to boil off with a "sizzle-like" sound.

Check bearing rotating torque with an inch pound torque wrench. The torque necessary to rotate the pinion gear should be: - Original Bearings - 1 to 3 Nm (10 to 20 inch lbs.). - New Bearings - 2 to 5 Nm (15 to 35 inch lbs.). 12. If the rotating torque is above the desired amount, remove the pinion yoke and increase the preload shim pack thickness. Increasing the shim pack thickness 0.025 mm (0.001 inch) will decrease the rotating torque approximately 0.9 Nm (8 inch lbs.). 13. Slowly tighten the nut in 6.8 Nm (5 ft. lbs.) increments until the maximum torque or the desired rotating torque is achieved. Measure the rotating torque frequently. 14. If the maximum tightening torque is reached prior to reaching the desired rotating torque, remove the pinion yoke and decrease the pinion preload shim pack thickness. Decreasing the shim pack thickness 0.025 mm (0.001 inch) will increase the rotating torque approximately 0.9 Nm (8 inch lbs.). 15.

MODELS: 1998-2001 (AB) Ram Van/Wagon SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight steering corrections are necessary to be able to keep the vehicle moving in a straight line. Steering wander can be created by a number of different conditions including but not limited to the following: ^ Non-factory installed options. ^ Tires or wheels of different size. ^ Aftermarket wheels. ^ Tires that have a belt that has shifted. ^ Incorrect tire pressure. ^ A vehicle that is carrying extra added weight (e.g. tool boxes). ^ Steering and/or suspension components that are worn or damaged. ^ Wheel bearings that are loose, worn, or damaged. ^ A vehicle that is not within alignment specifications. NOTE: UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER. The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering system components are functioning as designed and are not the root cause of steering wander. DIAGNOSIS: 1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to exceed the front or rear Gross Axle Weight Rating (GAWR). 2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to wander and should be replaced before continuing with the diagnosis. 3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove box). NOTE: TIRE PRESSURES ARE NORMALLY SET TO THE LIGHT LOAD SPECIFICATION WHEN PERFORMING STEERING WANDER DIAGNOSIS BUT, ONLY IF THE VEHICLE IS AT CURB OR LIGHT LOAD CONDITIONS. 4. Validate the customer's concern by test driving the vehicle on a smooth highway, free of road crown, ruts, speed bumps, or potholes. Drive the vehicle at speeds between 80 - 113 km/h (50 - 70 mph), preferably without cross wind conditions. If crosswind conditions are prevalent, drive the vehicle in both directions relative to the crosswind. Proceed to the next step if the vehicle exhibits a steering wander condition. NOTE: VEHICLES THAT DO NOT EXHIBIT A STEERING WANDER CONDITION DURING THE ROAD TEST MAY HAVE HAD THE CONDITION CORRECTED WITH STEPS 1-3 OR THE CONDITION MAY HAVE BEEN CAUSED BY ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, ETC.). 5. Raise the vehicle on an appropriate lift. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive Axles, Bearings and Joints > Wheel Bearing > Component Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 3571 6. Secure a dial indicator to the lower control arm. Position the dial indicator so that the tip of the indicator contacts the inside face of the rotor (Figure 1). 7. Place your hands at the top and bottom of the tire/wheel assembly and push the tire/wheel assembly inboard (Figure 2). Zero the dial indicator. With your hands at the top and bottom of the tire/wheel assembly, pull the tire/wheel assembly outboard (Figure 3). Record the dial indicator reading. Perform this procedure on both front wheel bearings and proceed to the next step if the wheel bearing endplay exceeds 0.025 - 0.076 mm (0.001 - 0.003 in.). Proceed to Step 9 if wheel-bearing endplay on both front wheel bearings are within specifications. NOTE: WHEEL BEARING INSPECTION AND ADJUSTMENT IS ONLY REQUIRED ON WHEEL BEARINGS EXCEEDING 0.025 - 0.076 MM (0.001 - 0.003 IN.) ENDPLAY. 8. Remove the wheel bearing protective end cap, cotter pin, nut lock, nut, and washer from the spindle. Inspect the wheel bearings. If it is determined that wheel bearing replacement is necessary, refer to the appropriate Ram Van/Wagon Service Manual, Group 02, Wheel Bearings, for removal and installation information. Reinstall the wheel bearings, washer, and adjustment nut if the wheel bearings pass the inspection. 9. Using a torque wrench, tighten the wheel bearing adjustment nut to 54 N.m (40 ft. lbs.) while rotating the tire/wheel assembly. Stop the wheel from rotating and loosen the nut. Using the procedure identified in Steps 6 and 7 to measure endplay, adjust the front wheel bearing endplay until 0.025 - 0.076 mm (0.001 - 0.003 in.) endplay has been achieved. Install the nut lock and a new cotter pin. 10. Perform the Pre-Alignment inspection as identified in Group 02, Service Procedures, of the appropriate Ram Van/Wagon Service Manual. Any worn steering and/or suspension component must be replaced prior to performing an alignment. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive Axles, Bearings and Joints > Wheel Bearing > Component Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 3572 11. Perform a wheel alignment on the vehicle. Refer to the procedures identified in the appropriate Ram Van/Wagon Service Manual, Group 02, Service Procedures, Wheel Alignment.

The use of the correct replacement parts helps to ensure safe operation. All fasteners must be torqued to the specified values for safe operation. Fig. 3 Also make alignment reference marks on the propeller shaft yoke and axle, or transmission, yoke prior to servicing. This helps to eliminate possible vibration. CAUTION: Do not allow the propeller shaft to drop or hang from any propeller shaft joint during removal. Attach the propeller shaft to the vehicle underside with wire to prevent damage to the joints. It is very important to protect the external machined surface of the slip yoke from damage during and after propeller shaft removal. If the yoke is damaged, the transmission extension seal may be damaged and therefore cause a leak. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller Shaft > Component Information > Description and Operation > General Information Drive/Propeller Shaft: Description and Operation General Information Fig. 1 The basic function of a propeller shaft is to transmit power from one point to another. The shaft is designed to send torque through an angle from the transmission to the axle. The propeller shaft must operate through constantly changing relative angles between the transmission and axle. It must also be capable of changing length while transmitting torque. The axle rides suspended by springs in a floating motion. This means the propeller shaft must be able to contract, expand and change operating angles. This is accomplished through universal joints. Universal joints permit the propeller shaft to operate at different angles. The slip yokes permit contraction or expansion. Tubular propeller shafts are balanced by the manufacturer with weights spot welded to the tube. Before undercoating a vehicle, the propeller shaft and the universal joints should be covered. This will prevent the undercoating front causing an out-of-balance condition and vibration. CAUTION: Use exact replacement parts for attaching the propeller shafts to ensure safe operation. The specified torque must always be applied when tightening the fasteners. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller Shaft > Component Information > Description and Operation > General Information > Page 3593 Drive/Propeller Shaft: Description and Operation Lubrication The factory installed universal joints are lubricated for the life of the vehicle. All universal joints should be inspected for leakage and damage each time the vehicle is serviced. If seal leakage or damage exists, the universal joint should be replaced. Refer to Maintenance, for additional information. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller Shaft > Component Information > Description and Operation > General Information > Page 3594 Drive/Propeller Shaft: Description and Operation Propeller Shaft Joint Angle When two shafts come together at a common joint, the bend that is formed is called the operating angle. The larger the angle, the larger the amount of angular acceleration and deceleration of the joint. This speeding up and slowing down of the joint must be cancelled to produce a smooth power flow. This is done through the phasing of a propeller shaft and ensuring that the proper propeller shaft joint working angles are maintained. A propeller shaft is properly phased when the yoke ends are in the same plane, or in line. A twisted shaft will make the yokes out of phase and cause a noticeable vibration. When taking propeller shaft joint angle measurements, or checking the phasing, of two piece shafts, consider each shaft separately. Ideally the driveline system should have: Angles that are equal or opposite within 1 degree of each other. - Have a 3 degree maximum operating angle. - Have at least a 1/2 degree continuous operating (propeller shaft) angle. Fig. 2 Engine speed (rpm) is the main factor in determining the maximum allowable operating angle. As a guide to the maximum normal operating angles refer to. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller Shaft > Component Information > Service and Repair > Procedures Drive/Propeller Shaft: Procedures 1.

Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

This solenoid is located in the transmission. An overdrive/override push-button switch is located at the end of transmission shift lever. The overdrive/override push-button switch is normally open (overdrive allowed) when the lamp is not illuminated. It momentarily closes (overdrive not allowed) when the operator presses the switch and the lamp is illuminated. Overdrive will revert to ON (lamp off) each time the ignition switch in turned on. The transmission downshifts if the operator presses the override switch while in overdrive. Refer to more transmission information. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Sensors and Switches - Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Position Switch/Sensor, A/T > Component Information > Locations Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Sensors and Switches - Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Position Switch/Sensor, A/T > Component Information > Locations > Page 3649 Transmission Position Switch/Sensor: Description and Operation TRANSMISSION PARK/NEUTRAL SWITCH - PCM INPUT The park/neutral switch is located on the transmission housing and provides an input to the powertrain control module (PCM).

The sensor is positioned over the park gear and monitors transmission output shaft rotating speed. Speed sensor signals are triggered by the park gear lugs as they rotate past the sensor pickup face. Input signals from the sensor are sent to the transmission control module for processing. The vehicle speed sensor also serves as a backup for the transmission speed sensor. Signals from this sensor are shared with the PCM. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Sensors and Switches - Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Locations Transmission Temperature Sensor/Switch: Locations Governor Pressure Sensor, Transmission Temperature Sensor, Governor Pressure Solenoid, Governor The transmission temperature sensor is located in the transmission solenoid assembly in the valve body. The governor pressure sender and the transmission fluid temperature thermistor are separate sensors in the same component. This component is attached to the governor body in the solenoid assembly of the valve body. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Sensors and Switches - Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - Description and Operation Transmission fluid temperature readings are supplied to the transmission control module by the thermistor. The temperature readings are used to control engagement of the fourth gear overdrive clutch, the converter clutch, and governor pressure. Normal resistance value for the thermistor at room temperature is approximately 1000 ohms. The PCM prevents engagement of the converter clutch and overdrive clutch, when fluid temperature is below approximately 10 °C (50 °F). If fluid temperature exceeds 126 °C (260 °F), the PCM causes a 4-3 downshift and engage the converter clutch. Engagement is according to the third gear converter clutch engagement schedule. The overdrive OFF lamp in the instrument panel illuminates when the shift back to third occurs. The transmission will not allow fourth gear operation until fluid temperature decreases to approximately 110 °C (230 °F). The thermistor is part of the governor pressure sensor assembly and is immersed in transmission fluid at all times. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Sensors and Switches - Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation > Page 3659 Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - PCM Input TRANSMISSION TEMPERATURE SENSOR - PCM INPUT This input is used in the shift operation for speed electronic transmissions only.

The lamp is controlled by the Powertrain Control Module (PCM). The lamp illuminates on the instrument panel to indicate when the driver should shift to the next highest gear for best fuel economy. The PCM will turn the lamp OFF after 3 to 5 seconds if the shift of gears is not performed. The lamp will remain off until vehicle stops accelerating and is brought back to range of up-shift lamp operation. This will also happen if vehicle is shifted into fifth gear. The indicator lamp is normally illuminated when the ignition switch is turned on and it is turned off when the engine is started up. With the engine running, the lamp is turned ON/OFF depending upon engine speed and load. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Overdrive Indicator Lamp > Component Information > Description and Operation Overdrive Indicator Lamp: Description and Operation OVERDRIVE LAMP - PCM OUTPUT This circuit controls a signal for the operation of the push-button overdrive lamp switch.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure. NOTE: WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION LEVEL.

Signals from this sensor are shared with the PCM. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Sensors and Switches Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Locations Transmission Temperature Sensor/Switch: Locations Governor Pressure Sensor, Transmission Temperature Sensor, Governor Pressure Solenoid, Governor The transmission temperature sensor is located in the transmission solenoid assembly in the valve body. The governor pressure sender and the transmission fluid temperature thermistor are separate sensors in the same component. This component is attached to the governor body in the solenoid assembly of the valve body. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Sensors and Switches Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - Description and Operation Transmission fluid temperature readings are supplied to the transmission control module by the thermistor. The temperature readings are used to control engagement of the fourth gear overdrive clutch, the converter clutch, and governor pressure. Normal resistance value for the thermistor at room temperature is approximately 1000 ohms. The PCM prevents engagement of the converter clutch and overdrive clutch, when fluid temperature is below approximately 10 °C (50 °F). If fluid temperature exceeds 126 °C (260 °F), the PCM causes a 4-3 downshift and engage the converter clutch. Engagement is according to the third gear converter clutch engagement schedule. The overdrive OFF lamp in the instrument panel illuminates when the shift back to third occurs. The transmission will not allow fourth gear operation until fluid temperature decreases to approximately 110 °C (230 °F). The thermistor is part of the governor pressure sensor assembly and is immersed in transmission fluid at all times. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Sensors and Switches Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation > Page 3738 Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - PCM Input TRANSMISSION TEMPERATURE SENSOR - PCM INPUT This input is used in the shift operation for speed electronic transmissions only.

The modulated hydraulic pressure is used to prevent wheel lock up during braking. The CAB also provides a vehicle speed signal (VSS) to the powertrain control module. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 3844 Electronic Brake Control Module: Description and Operation With Four Wheel Antilock Brakes CAB/HCU The Controller Antilock Brake (CAB) is mounted on the top of the hydraulic control unit. The CAB operates the ABS system and is separate from other vehicle electrical circuits. CAB voltage source is through the ignition switch in the RUN position. The CAB contains dual microprocessors. A logic block in each microprocessor receives identical sensor signals. These signals are processed and compared simultaneously. The CAB 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 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 CAB needs to be replaced the rear axle type and tire revolutions per mile must be programmed into the new CAB. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 3845 Electronic Brake Control Module: Description and Operation With Rear Wheel Antilock Brakes RWAL CAB The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring, and controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics. - Monitors the RWAL brake system for proper operation. - Controls the RWAL valve solenoids. NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB. SYSTEM SELF-TEST When the ignition switch is turned ON the microprocessor RAM and ROM are tested. If an error occurs during the test a DTC will be set into the RAM memory. However it is possible the DTC will not be stored in memory if the error has occurred in the RAM module were the DTCs are stored. Also it is possible a DTC may not be stored if the error has occurred in the ROM which signals the RAM to store the DTC. CAB INPUTS The CAB continuously monitors the speed of the differential ring gear by monitoring signals generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency when it recognizes the ring gear decelerating too rapidly. The CAB monitors the following inputs to determine when a wheel locking tendency may exists: Rear Wheel Speed Sensor - Brake Lamp Switch - Brake Warning Lamp Switch - Reset Switch CAB OUTPUTS The CAB controls the following outputs for antilock braking and brake warning information: RWAL Valve - ABS Warning Lamp - Brake Warning Lamp Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Electronic Brake Control Module > Component Information > Service and Repair > With Four Wheel Antilock System Electronic Brake Control Module: Service and Repair With Four Wheel Antilock System NOTE: If the Controller Antilock Brake (CAB) needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB.

The pump, motor, and accumulator are combined into an assembly attached to the valve body. The accumulator store the extra fluid which had to be dumped from the brakes. This is done to prevent the wheels from locking up. The pump provides the fluid volume needed and is operated by a DC type motor. The motor is controlled by the Controller Antilock Brake (CAB). The valve body contains the solenoid valves. 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. The valves are not static. They are cycled rapidly and continuously to modulate pressure and control wheel slip and deceleration. 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. During antilock braking, solenoid valve pressure modulation occurs in three stages, pressure decrease, pressure hold, and pressure increase. The valves are all contained in the valve body portion of the HCU. PRESSURE DECREASE The inlet valve is closed and the outlet valve is opened 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 to prevent the driver from further increasing the brake pressure and locking the brakes. The CAB 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. 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 counteract unequal wheel speeds. This cycle controls re-application of fluid apply pressure due to changing road surfaces or wheel speed. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Hydraulic Control Assembly - Antilock Brakes > Component Information > Description and Operation > With Four Wheel Antilock Brakes > Page 3859 Hydraulic Control Assembly - Antilock Brakes: Description and Operation With Rear Wheel Antilock Brakes If the Controller Antilock Brake (CAB) senses that rear wheel speed deceleration is excessive, it will energize an isolation solenoid by providing battery voltage to the solenoid. This prevents a further increase of driver induced brake pressure to the rear wheels. If this initial action is not enough to prevent rear wheel lock-up, the CAB will momentarily energize a dump solenoid (the CAB energizes the dump solenoid by providing battery voltage to the solenoid). This opens the dump valve to vent a small amount of isolated rear brake pressure to an accumulator. The action of fluid moving to the accumulator reduces the isolated brake pressure at the wheel cylinders. The dump (pressure venting) cycle is limited to very short time periods (milliseconds). The CAB will pulse the dump valve until rear wheel deceleration matches the vehicle deceleration rate or the desired slip rate programmed into the CAB. The system will switch to normal braking once wheel locking tendencies are no longer present. A predetermined maximum number of consecutive dump cycles can be performed during any one antilock stop. If excessive dump cycles occur, a Diagnostic Trouble Code (DTC) will be set and stored in the CAB memory. If during an antilock stop, the driver releases the brake pedal, the reset switch contacts will open. This signal to the CAB is an indication that pressure has equalized across the RWAL valve. The CAB will then reset the dump cycle counter in anticipation of the next antilock stop. Additionally, any fluid stored in the accumulator will force its way past the dump valve, back into the hydraulic circuit and return to the master cylinder. A fuse internal to the CAB, provides a fail-safe device which prevents unwanted control over the isolation and dump solenoids. The fuse is in series with the isolation and dump solenoids output circuits. If the internal fuse is open, the CAB cannot provide voltage to energize either solenoid and antilock stops are prevented. If the fuse is open, the braking system will operate normally but without antilock control over rear brake pressure. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Hydraulic Control Assembly - Antilock Brakes > Component Information > Service and Repair > Front Antilock Valve Replacement Hydraulic Control Assembly - Antilock Brakes: Service and Repair Front Antilock Valve Replacement NOTE: If the antilock control assembly needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new Controller Antilock Brake (CAB).

A sensor is mounted to each front steering knuckles. The third sensor is mounted on top of the rear axle differential housing. The sensor is a magnet coil that is mounted over a tone wheel front/exciter ring rear with an air gap between them. The sensors measure the wheel speed by monitoring the rotation of the tone wheels front/exciter ring rear. As the teeth of the tone wheels front/exciter ring rear move through the magnetic field of the sensor an AC voltage is generated. This signal frequency increases or decreases proportionally to the speed of the wheel. The Controller Antilock Brake (CAB) monitors these signals for changes in wheel deceleration. If the CAB detects a sudden wheel or wheels deceleration within a predetermined amount the CAB will activate the ABS system. CIRCUIT OPERATION The all wheel Anti-Lock Brake System (ABS) uses three wheel speed sensors; a single sensor for both rear wheels and individual sensors for the front wheels. The single sensor used for the rear wheels mounts on the top of the rear axle differential housing. Each sensor converts wheel speed into an electrical signal that is transmitted to the Controller Anti-Lock Brakes (CAB). A pair of twisted wires connect to each sensor and provide signals to the CAB. Circuits B6 and B7 provide signals to the CAB from the right front wheel speed sensor. Circuit B6, which provides the LOW signal, connects to cavity 15 of the CAB. Circuit B7 connects to cavity 2 of the CAB and provides the HIGH signal. Circuits B8 and B9 provide signals to the CAB from the left front wheel speed sensor. Circuit B8, which provides the LOW signal, connects to cavity 16 of the CAB. Circuit B9 connects to cavity 3 and provides the HIGH signal. Circuit B114 connects to cavity 14 of the CAB and to circuit B2 of the rear wheel speed sensor harness at the sensor connector. Circuit B113 connects to cavity 1 of the CAB and to circuit B1 at the rear wheel speed sensor harness connector. Circuit B114 provides the rear wheel speed sensor LOW input while circuit B113 provides the HIGH input. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Wheel Speed Sensor > Component Information > Description and Operation > Four Wheel Antilock Brakes > Page 3878 Wheel Speed Sensor: Description and Operation Rear Wheel Antilock Brakes The rear wheel speed sensor is mounted on the top of the rear axle differential. The sensor converts wheel speed into an electrical signal that is transmitted to the Rear Wheel Anti-Lock (RWAL) control module. Circuits B113 and B114, a pair of twisted wires connect to the sensor and provide signals to the RWAL control module. These circuits also connect to the rolls test connector used only during manufacture of the vehicle. Circuit B113 connects to cavity 14 of the RWAL control module and to circuit B1 of the wheel speed sensor harness. Circuit B114 connects to cavity 13 of the RWAL control module and circuit B2 of the sensor harness. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Wheel Speed Sensor > Component Information > Service and Repair > Wheel Speed Sensor Replacement Wheel Speed Sensor: Service and Repair Wheel Speed Sensor Replacement Front REMOVAL 1.

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. W/ Rear Wheel Antilock Brakes Use Mopar 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. Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into small bubbles that are distributed throughout the hydraulic system. This will make additional bleeding operations necessary. Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow additional air to be drawn into the system. Check the cylinder fluid level frequently and add fluid as needed. Bleed only one brake component at a time in the following sequence: Master Cylinder - Combination Valve - Rear Antilock Valve - Left Rear Wheel - Right Rear Wheel - Right Front Wheel - Left Front Wheel MANUAL BLEEDING 1. Remove reservoir filler caps and fill reservoir. 2. If calipers, or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws. Then close each bleed screw as fluid starts to drip from it. Top off master cylinder reservoir once more before proceeding. Bleed Hose Setup 3. Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially filled with brake fluid. Be sure end of bleed hose is immersed in fluid. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures > Page 3887 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. PRESSURE BLEEDING If pressure bleeding equipment will be used, the front brake metering valve will have to be held open to bleed the front brakes. The valve stem is located in the forward end or top of the combination valve. The stem must either be pressed inward, or held outward slightly. A spring clip tool or helper is needed to hold the valve stem in position. Follow the tank manufacturer's instructions carefully when using pressure equipment. Do not exceed the tank manufacturer's pressure recommendations. Generally, a tank pressure of 16-20 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. Use the adapter provided with the equipment or Adapter 6921. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures > Page 3888 Brake Bleeding: Service and Repair Base Brake System Bleeding Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only.

The red light illuminates for approximately 2-4 seconds at engine start up. This is a self test feature designed to check bulb operation. The red warning lamp illuminates when the parking brake is applied. It also illuminates if a fluid pressure drop occurs in either the front or rear brake hydraulic circuit. A pressure drop moves the valve in the combination valve toward the low pressure side. When the valve moves it pushes the pressure differential switch contact plunger upward. This closes the contacts and completes the circuit to the lamp. The lamp will remain on until repairs are made and normal fluid pressure is restored. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Description and Operation > General Information > Page 3900 Brake Warning Indicator: Description and Operation Brake Warning Lamp Description The red brake warning lamp is used to alert the driver of a hydraulic fault or that the parking brake is applied. For the RWAL system, the red brake warning lamp also is used to alerts the driver of a problem with the RWAL system. The brake warning lamp illuminates when a message is sent over the bus to the cluster to illuminate the bulb. A ground for the bulb is provided when: The brakes are applied and the park brake switch is actuated. - A hydraulic fault has occurred and the pressure differential switch is actuated. - A RWAL fault has occurred. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Description and Operation > Page 3901 Brake Warning Indicator: Testing and Inspection HARD WIRED LAMP DIAGNOSIS Each of the lamps depends upon a hard wired circuit input to the instrument cluster for proper operation.

The specification is either stamped or cast into the hub surface. ROTOR RUNOUT Checking Rotor Runout And Thickness Variation Check rotor lateral runout with dial indicator C-3339. Excessive lateral runout will cause brake pedal pulsation and rapid, uneven wear of the brake pads. Position the dial indicator plunger approximately 25.4 mm (1 inches) inward from the rotor edge. Maximum allowable rotor runout is 0.102 mm (0.004 inches) ROTOR THICKNESS VARIATION Variations in rotor thickness will cause pedal pulsation, noise and shudder. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Specifications > Page 3923 Measuring Rotor Thickness Measure rotor thickness at 6 to 12 points around the rotor face. Position the micrometer approximately 25.4 mm (1 inches) from the rotor outer circumference for each measurement. Thickness should not vary by more than 0.013 mm (0.0005 inches) from point-to-point on the rotor. Machine or replace the rotor if necessary. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Service and Repair > Rotor Removal and Installation Brake Rotor/Disc: Service and Repair Rotor Removal and Installation REMOVAL 1.

Generally, a drum can be machined to a maximum of 1.52 mm (0.060 inches) oversize. Always replace the drum if machining would cause drum diameter to exceed the size limit indicated on the drum. BRAKE DRUM RUNOUT Measure drum diameter and runout with an accurate gauge. The most accurate method of measurement involves mounting the drum in a brake lathe and checking variation and runout with a dial indicator. Variations in drum diameter should not exceed 0.076 mm (0.003 inches). Drum runout should not exceed 0.20 mm (0.008 inches) out of round. Machine the drum if runout or variation exceed these values. Replace the drum if machining causes the drum to exceed the maximum allowable diameter. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Drum Brake System > Brake Drum > Component Information > Specifications > Page 3937 Brake Drum: Service and Repair MACHINING The brake drums can be machined on a drum lathe when necessary. Initial machining cuts should be limited to 0.12-0.20 mm (0.005-0.008 inches) at a time as heavier feed rates can produce taper and surface variation. Final finish cuts of 0.025 to 0.038 mm (0.001 to 0.0015 inches) are recommended and will generally provide the best surface finish. Be sure the drum is securely mounted in the lathe before machining operations. A damper strap should always be used around the drum to reduce vibration and avoid chatter marks. The maximum allowable diameter of the drum braking surface is stamped or cast into the drum outer edge. CAUTION: Replace the drum if machining will cause the drum to exceed the maximum allowable diameter. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Drum Brake System > Brake Shoe > Component Information > Specifications Brake Shoe: Specifications As a general rule, riveted brake shoes should be replaced when worn to within 0.78 mm (1/32 inch) of the rivet heads.

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. W/ Rear Wheel Antilock Brakes Use Mopar 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. Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into small bubbles that are distributed throughout the hydraulic system. This will make additional bleeding operations necessary. Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow additional air to be drawn into the system. Check the cylinder fluid level frequently and add fluid as needed. Bleed only one brake component at a time in the following sequence: Master Cylinder - Combination Valve - Rear Antilock Valve - Left Rear Wheel - Right Rear Wheel - Right Front Wheel - Left Front Wheel MANUAL BLEEDING 1. Remove reservoir filler caps and fill reservoir. 2. If calipers, or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws. Then close each bleed screw as fluid starts to drip from it. Top off master cylinder reservoir once more before proceeding. Bleed Hose Setup 3. Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially filled with brake fluid. Be sure end of bleed hose is immersed in fluid. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures > Page 3958 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. PRESSURE BLEEDING If pressure bleeding equipment will be used, the front brake metering valve will have to be held open to bleed the front brakes. The valve stem is located in the forward end or top of the combination valve. The stem must either be pressed inward, or held outward slightly. A spring clip tool or helper is needed to hold the valve stem in position. Follow the tank manufacturer's instructions carefully when using pressure equipment. Do not exceed the tank manufacturer's pressure recommendations. Generally, a tank pressure of 16-20 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. Use the adapter provided with the equipment or Adapter 6921. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures > Page 3959 Brake Bleeding: Service and Repair Base Brake System Bleeding Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only.

In case of contact, take the following actions: * Eye Contact-rinse eyes thoroughly with water. * Skin Contact-wash skin with soap and water. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Fluid > Component Information > Specifications > Page 3974 Brake Fluid: Testing and Inspection CAUTION: The hydraulic fluid used in automotive brake systems is hygroscopic. This means that the hydraulic fluid tends to absorb moisture from the atmosphere over periods of time. As hydraulic brake fluid absorbs moisture, it effects the function of the vehicles hydraulic brake system. For this reason, the vehicle's hydraulic brake fluid should be drained and replaced using fresh clean hydraulic brake fluid every two years. When replacing hydraulic brake fluid, use only Mopar brake fluid or an equivalent from a sealed container. Brake fluid must conform to DOT 3 specifications. BRAKE FLUID CONTAMINATION Indications of fluid contamination are swollen or deteriorated rubber parts. Swelling indicates 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 the fluid separates into layers, there is mineral oil or other fluid contamination of the brake fluid. If the brake fluid is contaminated, drain and thoroughly flush the brake system. Replace all the rubber parts or components containing rubber coming into contact with the brake fluid. This includes the master cylinder, proportioning valves, caliper seals, wheel cylinder seals, ABS hydraulic control unit (HCU), and all hydraulic fluid hoses. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Fluid > Component Information > Specifications > Page 3975 Brake Fluid: Service and Repair BRAKE FLUID LEVEL Always clean the master cylinder filler caps before checking fluid level. If not cleaned, dirt from the caps could enter the fluid. Correct fluid level is to the bottom of the ring indicators on the reservoir. If necessary, add fluid to correct the level. With disc brake equipped vehicles, fluid level in the front brake reservoir will decrease slightly in proportion to normal lining wear. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Fluid Pressure Sensor/Switch > Component Information > Diagrams Connector Pin Identification Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Hose/Line > Component Information > Description and Operation Brake Hose/Line: Description and Operation Flexible rubber hose is used at both front brakes and at the rear axle junction block.

Inspect the hoses whenever the brake system is serviced, at every engine oil change, or whenever the vehicle is in for service. Inspect the hoses for surface cracking, scuffing, or worn spots. Replace any brake hose immediately if the fabric casing of the hose is exposed due to cracks or abrasions. Also check brake hose installation. Faulty installation can result in kinked, twisted hoses, or contact with the wheels and tires or other chassis components. All of these conditions can lead to scuffing, cracking and eventual failure. The steel brake lines should be inspected periodically for evidence of corrosion, twists, kinks, leaks, or other damage. Heavily corroded lines will eventually rust through causing leaks. In any case, corroded or damaged brake lines should be replaced. Factory replacement brake lines and hoses are recommended to ensure quality, correct length and superior fatigue life. Care should be taken to make sure that brake line and hose mating surfaces are clean and free from nicks and burrs. Also remember that right and left brake hoses are not interchangeable. Use new copper seal washers at all caliper connections. Be sure brake line connections are properly made (not cross threaded) and tightened to recommended torque. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Hose/Line > Component Information > Description and Operation > Page 3983 Brake Hose/Line: Service and Repair A preformed metal brake tube is recommended and preferred for all repairs. However, double-wall steel tube can be used for emergency repair when factory replacement parts are not readily available. Inverted Flare And ISO Flare Special bending tools are needed to avoid kinking or twisting of metal brake tubes. Special flaring tools are needed to make a double inverted flare or ISO flare. DOUBLE INVERTED FLARING 1. Cut off damaged tube with Tubing Cutter. 2. Ream cut edges of tubing to ensure proper flare. 3. Install replacement tube nut on the tube. 4. Insert tube in flaring tool. 5.

The combination valve/rear brake proportioning valve are not repairable and must be replaced as an assembly. PRESSURE DIFFERENTIAL SWITCH The pressure differential switch is connected to the brake warning lamp. The switch is triggered by movement of the switch valve. The purpose of the switch is to monitor fluid pressure in the separate front/rear brake hydraulic circuits. A decrease or loss of fluid pressure in either hydraulic circuit will cause the switch valve to shuttle forward or rearward in response to the pressure differential. Movement of the switch valve will push the switch plunger upward. This closes the switch internal contacts completing the electrical circuit to the warning lamp. The switch valve may remain in an actuated position until repair restores system pressures to normal levels. METERING VALVE Metering valve operation can be checked visually with the aid of a helper. Observe the metering valve stem while a helper applies and releases the brakes. If the valve is operating correctly, the stem will extend slightly when the brakes are applied and retract when the brakes are released. If the valve is faulty, replace the entire combination valve as an assembly. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Proportioning/Combination Valve > Component Information > Description and Operation > Combination Valve > Page 3989 Brake Proportioning/Combination Valve: Description and Operation Proportioning Valve The proportioning valve is used to balance front rear brake action at high decelerations. The valve allows normal fluid flow during moderate braking. The valve only controls fluid flow during high decelerations brake stops, when a percentage of rear weight is transferred to the front wheels. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Proportioning/Combination Valve > Component Information > Testing and Inspection > Combination Valve Testing Brake Proportioning/Combination Valve: Testing and Inspection Combination Valve Testing METERING VALVE The metering valve is used to balance brake action between the front disc and rear drum brakes. The valve holds off the initial pressure to the front disc brakes until the rear brake shoes retracting springs are overcome. The valve is designed to maintain front brake fluid pressure at 241-517 kPa (35-75 psi) until the hold-off limit of 310-689 kPa (100 psi) is reached. At this point, the metering valve opens completely permitting full fluid apply pressure to the front disc brakes. This reduces front brake lining wear during low deceleration stops. PRESSURE DIFFERENTIAL SWITCH 1. Have helper sit in drivers seat to apply brake pedal and observe red brake warning light. 2. Raise vehicle on hoist. 3. Connect bleed hose to a rear wheel cylinder and immerse hose end in container partially filled with brake fluid. 4. Have helper press and hold brake pedal to floor and observe warning light. a. If warning light illuminates, switch is operating correctly. b. If light fails to illuminate, check circuit fuse, bulb, and wiring. The parking brake switch can be used to aid in identifying whether or not the brake light bulb and fuse is functional. Repair or replace parts as necessary and test differential pressure switch operation again. 5. If warning light still does not illuminate, switch is faulty. Replace combination valve assembly, bleed brake system and verify proper switch and valve operation. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Proportioning/Combination Valve > Component Information > Testing and Inspection > Combination Valve Testing > Page 3992 Brake Proportioning/Combination Valve: Testing and Inspection Proportioning Valve Testing Road test the vehicle and make several hard brake applications. If a premature rear wheel skid occurs this could be an indication the proportioning valve has malfunctioned. 1. Inspect and verify the rear brakes are clean, adjusted and operating properly. 2. Check the pressure in and out of the valve. The pressure should be equal up to the 250 psi split point. 3. Above 250 psi the output pressure should decrease on a .43 slope. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Proportioning/Combination Valve > Component Information > Testing and Inspection > Page 3993 Brake Proportioning/Combination Valve: Service and Repair REMOVAL 1.

The pump, motor, and accumulator are combined into an assembly attached to the valve body. The accumulator store the extra fluid which had to be dumped from the brakes. This is done to prevent the wheels from locking up. The pump provides the fluid volume needed and is operated by a DC type motor. The motor is controlled by the Controller Antilock Brake (CAB). The valve body contains the solenoid valves. 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. The valves are not static. They are cycled rapidly and continuously to modulate pressure and control wheel slip and deceleration. 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. During antilock braking, solenoid valve pressure modulation occurs in three stages, pressure decrease, pressure hold, and pressure increase. The valves are all contained in the valve body portion of the HCU. PRESSURE DECREASE The inlet valve is closed and the outlet valve is opened 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 to prevent the driver from further increasing the brake pressure and locking the brakes. The CAB 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. 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 counteract unequal wheel speeds. This cycle controls re-application of fluid apply pressure due to changing road surfaces or wheel speed. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Hydraulic Control Assembly Antilock Brakes > Component Information > Description and Operation > With Four Wheel Antilock Brakes > Page 4003 Hydraulic Control Assembly - Antilock Brakes: Description and Operation With Rear Wheel Antilock Brakes If the Controller Antilock Brake (CAB) senses that rear wheel speed deceleration is excessive, it will energize an isolation solenoid by providing battery voltage to the solenoid. This prevents a further increase of driver induced brake pressure to the rear wheels. If this initial action is not enough to prevent rear wheel lock-up, the CAB will momentarily energize a dump solenoid (the CAB energizes the dump solenoid by providing battery voltage to the solenoid). This opens the dump valve to vent a small amount of isolated rear brake pressure to an accumulator. The action of fluid moving to the accumulator reduces the isolated brake pressure at the wheel cylinders. The dump (pressure venting) cycle is limited to very short time periods (milliseconds). The CAB will pulse the dump valve until rear wheel deceleration matches the vehicle deceleration rate or the desired slip rate programmed into the CAB. The system will switch to normal braking once wheel locking tendencies are no longer present. A predetermined maximum number of consecutive dump cycles can be performed during any one antilock stop. If excessive dump cycles occur, a Diagnostic Trouble Code (DTC) will be set and stored in the CAB memory. If during an antilock stop, the driver releases the brake pedal, the reset switch contacts will open. This signal to the CAB is an indication that pressure has equalized across the RWAL valve. The CAB will then reset the dump cycle counter in anticipation of the next antilock stop. Additionally, any fluid stored in the accumulator will force its way past the dump valve, back into the hydraulic circuit and return to the master cylinder. A fuse internal to the CAB, provides a fail-safe device which prevents unwanted control over the isolation and dump solenoids. The fuse is in series with the isolation and dump solenoids output circuits. If the internal fuse is open, the CAB cannot provide voltage to energize either solenoid and antilock stops are prevented. If the fuse is open, the braking system will operate normally but without antilock control over rear brake pressure. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Hydraulic Control Assembly Antilock Brakes > Component Information > Service and Repair > Front Antilock Valve Replacement Hydraulic Control Assembly - Antilock Brakes: Service and Repair Front Antilock Valve Replacement NOTE: If the antilock control assembly needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new Controller Antilock Brake (CAB).

A dual diaphragm, vacuum operated power brake booster is used to provide assist. The booster unit consists of a single housing divided into separate chambers by two internal diaphragms. The outer edge of the diaphragm is secured to the housing. The booster push rod, which connects the booster to the brake pedal and master cylinder, is attached to the center of the diaphragm. A check valve is used in the booster inlet and is connected to the engine intake manifold. Power assist is generated utilizing a combination of vacuum and atmospheric pressure to boost brake assist. NOTE: The power brake booster is not a repairable component. The booster must be replaced as an assembly if diagnosis indicates a malfunction has occurred. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Power Brake Assist > Vacuum Brake Booster > Component Information > Specifications > Page 4040 Vacuum Brake Booster: Testing and Inspection 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 stop 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 Typical Booster Vacuum Test Connections 1. Connect vacuum gauge to booster check valve with short length of hose and T-fitting. 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 hose shut between vacuum source and check valve. 5. Stop engine and observe vacuum gauge. 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. 2. Remove check valve and valve seal from booster. 3. Use a hand operated vacuum pump for test. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Power Brake Assist > Vacuum Brake Booster > Component Information > Specifications > Page 4041 Vacuum Check Valve And Seal 4.

The modulated hydraulic pressure is used to prevent wheel lock up during braking. The CAB also provides a vehicle speed signal (VSS) to the powertrain control module. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 4135 Electronic Brake Control Module: Description and Operation With Four Wheel Antilock Brakes CAB/HCU The Controller Antilock Brake (CAB) is mounted on the top of the hydraulic control unit. The CAB operates the ABS system and is separate from other vehicle electrical circuits. CAB voltage source is through the ignition switch in the RUN position. The CAB contains dual microprocessors. A logic block in each microprocessor receives identical sensor signals. These signals are processed and compared simultaneously. The CAB 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 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 CAB needs to be replaced the rear axle type and tire revolutions per mile must be programmed into the new CAB. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 4136 Electronic Brake Control Module: Description and Operation With Rear Wheel Antilock Brakes RWAL CAB The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring, and controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics. - Monitors the RWAL brake system for proper operation. - Controls the RWAL valve solenoids. NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB. SYSTEM SELF-TEST When the ignition switch is turned ON the microprocessor RAM and ROM are tested. If an error occurs during the test a DTC will be set into the RAM memory. However it is possible the DTC will not be stored in memory if the error has occurred in the RAM module were the DTCs are stored. Also it is possible a DTC may not be stored if the error has occurred in the ROM which signals the RAM to store the DTC. CAB INPUTS The CAB continuously monitors the speed of the differential ring gear by monitoring signals generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency when it recognizes the ring gear decelerating too rapidly. The CAB monitors the following inputs to determine when a wheel locking tendency may exists: - Rear Wheel Speed Sensor - Brake Lamp Switch - Brake Warning Lamp Switch - Reset Switch CAB OUTPUTS The CAB controls the following outputs for antilock braking and brake warning information: RWAL Valve - ABS Warning Lamp - Brake Warning Lamp Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Service and Repair > With Four Wheel Antilock System Electronic Brake Control Module: Service and Repair With Four Wheel Antilock System NOTE: If the Controller Antilock Brake (CAB) needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB.

A sensor is mounted to each front steering knuckles. The third sensor is mounted on top of the rear axle differential housing. The sensor is a magnet coil that is mounted over a tone wheel front/exciter ring rear with an air gap between them. The sensors measure the wheel speed by monitoring the rotation of the tone wheels front/exciter ring rear. As the teeth of the tone wheels front/exciter ring rear move through the magnetic field of the sensor an AC voltage is generated. This signal frequency increases or decreases proportionally to the speed of the wheel. The Controller Antilock Brake (CAB) monitors these signals for changes in wheel deceleration. If the CAB detects a sudden wheel or wheels deceleration within a predetermined amount the CAB will activate the ABS system. CIRCUIT OPERATION The all wheel Anti-Lock Brake System (ABS) uses three wheel speed sensors; a single sensor for both rear wheels and individual sensors for the front wheels. The single sensor used for the rear wheels mounts on the top of the rear axle differential housing. Each sensor converts wheel speed into an electrical signal that is transmitted to the Controller Anti-Lock Brakes (CAB). A pair of twisted wires connect to each sensor and provide signals to the CAB. Circuits B6 and B7 provide signals to the CAB from the right front wheel speed sensor. Circuit B6, which provides the LOW signal, connects to cavity 15 of the CAB. Circuit B7 connects to cavity 2 of the CAB and provides the HIGH signal. Circuits B8 and B9 provide signals to the CAB from the left front wheel speed sensor. Circuit B8, which provides the LOW signal, connects to cavity 16 of the CAB. Circuit B9 connects to cavity 3 and provides the HIGH signal. Circuit B114 connects to cavity 14 of the CAB and to circuit B2 of the rear wheel speed sensor harness at the sensor connector. Circuit B113 connects to cavity 1 of the CAB and to circuit B1 at the rear wheel speed sensor harness connector. Circuit B114 provides the rear wheel speed sensor LOW input while circuit B113 provides the HIGH input. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Sensors and Switches - Brakes and Traction Control > Wheel Speed Sensor > Component Information > Description and Operation > Four Wheel Antilock Brakes > Page 4160 Wheel Speed Sensor: Description and Operation Rear Wheel Antilock Brakes The rear wheel speed sensor is mounted on the top of the rear axle differential. The sensor converts wheel speed into an electrical signal that is transmitted to the Rear Wheel Anti-Lock (RWAL) control module. Circuits B113 and B114, a pair of twisted wires connect to the sensor and provide signals to the RWAL control module. These circuits also connect to the rolls test connector used only during manufacture of the vehicle. Circuit B113 connects to cavity 14 of the RWAL control module and to circuit B1 of the wheel speed sensor harness. Circuit B114 connects to cavity 13 of the RWAL control module and circuit B2 of the sensor harness. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Sensors and Switches - Brakes and Traction Control > Wheel Speed Sensor > Component Information > Service and Repair > Wheel Speed Sensor Replacement Wheel Speed Sensor: Service and Repair Wheel Speed Sensor Replacement Front REMOVAL 1.

The starter relay is located in the Power Distribution Center (PDC), in the engine compartment. See the fuse and relay layout label affixed to the inside surface of the PDC cover for starter relay identification and location. The starter relay is a International Standards Organization (ISO) micro-relay. Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal patterns and terminal functions. 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 starter relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION 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 the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Relays and Modules - Starting and Charging > Starter Relay > Component Information > Locations > Page 4198 Starter Relay: Testing and Inspection STARTER RELAY Starter Relay The starter relay is located in the Power Distribution Center (PDC), in the engine compartment. Refer to the fuse and relay layout label affixed to the underside of the PDC cover for starter relay identification and location. 1. Remove the starter relay from the PDC. Refer to Starter Relay in the Replacement for the procedures. 2. A relay in the 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 the 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 the faulty relay 4. Connect a battery to terminals 85 and 86. There should now be continuity between terminals 30 and 87, and no continuity between terminals 87A and 30. If OK, perform the Relay Circuit Test that follows. If not OK, replace the 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 the open circuit to the fuse in the 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 the common feed terminal (30) in the energized position. This terminal supplies battery voltage to the starter solenoid field coils. There should be continuity between the cavity for relay terminal 87 and the starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair the open circuit to the starter solenoid as required. 4. The coil battery terminal (86) is connected to the electromagnet in the relay It is energized when the ignition switch is held in the START position. Check for battery voltage at the cavity for relay terminal 86 with the ignition switch in the START position, and no voltage when the ignition switch is released to the ON position. If OK, go to Step 5. If not OK, check for an open or short circuit to the ignition switch and repair, if required. If the circuit to the ignition switch is OK, refer to Ignition Switch and Key Lock Cylinder Diagnosis and Testing for testing of the ignition switch. 5. The coil ground terminal (85) is connected to the electromagnet in the relay. It is grounded through the park/neutral position switch only when the gearshift selector lever is in the Park or Neutral positions. Check for continuity to ground at the cavity for relay terminal 85. If not OK, check for an open or short circuit to the park/neutral position switch and repair, if required. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Relays and Modules - Starting and Charging > Starter Relay > Component Information > Locations > Page 4199 Starter Relay: Service and Repair Power Distribution Center REMOVAL 1.

It is serviced only as a complete assembly. If the generator fails for any reason, the entire assembly must be replaced. OPERATION 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 Y type stator winding connections deliver the induced AC current to 3 positive and 3 negative diodes for rectification. From the diodes, rectified DC 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 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. GENERATOR FIELD SOURCE (+) - PCM OUTPUT This output from the Powertrain Control Module (PCM) regulates charging system voltage to the generator field source (+) circuit. The voltage range is 12.9 to 15.0 volts. Models of previous years had used the ASD relay (directly) to apply the 12 volt + power supply to the generator field source (+) circuit. GENERATOR FIELD DRIVER (-) - PCM OUTPUT OPERATION This output from the Powertrain Control Module (PCM) regulates charging system ground control to the generator field driver (-) circuit. GENERATOR LAMP - PCM OUTPUT If the Powertrain Control Module (PCM) senses low charging condition in the charging system, it will,illuminate the generator lamp (if equipped) on the instrument panel. This is done through the CCD BUS circuits. For example, during low idle with all accessories turned on, the lamp may momentarily go on Once the PCM corrects idle speed to a higher rpm the lamp will go out. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Locations > Page 4223 Alternator: Service and Repair REMOVAL WARNING: DISCONNECT NEGATIVE CABLE FROM BATTERY BEFORE REMOVING BATTERY OUTPUT WIRE (B+ WIRE) FROM GENERATOR.

It is actually a voltage regulating circuit located within the Powertrain Control Module (PCM). The EVR is not serviced separately. If replacement is necessary, the PCM must be replaced. OPERATION The amount of DC 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 and battery temperature (refer to Battery Temperature Sensor for more information). It then compensates and regulates generator current output accordingly. Also refer to Charging System Operation for additional information. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Ignition Switch Lock Cylinder > Component Information > Description and Operation Ignition Switch Lock Cylinder: Description and Operation IGNITION SWITCH AND KEY LOCK CYLINDER The ignition switch is located on the steering column.

The starter motors are all mounted with one screw, a stud and a nut to the automatic transmission torque converter housing and are located on the left side of the engine. This starter motor incorporates several features to create a reliable, efficient, compact, lightweight and powerful unit. The electric motors of these starters feature four electromagnetic field coils wound around four pole shoes, and four brushes contact the motor commutator. These starter motors are all rated at 1.4 kilowatts (about 1.9 horsepower) output at 12 volts. These starter motors are serviced only as a unit with their starter solenoids, and cannot be repaired. If either component is faulty or damaged, the entire starter motor and starter solenoid unit must be replaced. OPERATION This starter motor is equipped with a gear reduction (intermediate transmission) system. The gear reduction system consists of a gear that is integral to the output end of the electric motor armature shaft that is in continual engagement with a larger gear that is splined to the input end of the starter pillion gear shaft. This feature makes it possible to reduce the dimensions of the starter. At the same time, it allows higher armature rotational speed and delivers increased torque through the starter pinion gear to the starter ring gear. These starter motors are activated by an integral heavy duty starter solenoid switch mounted to the overrunning clutch housing. This electromechanical switch connects and disconnects the feed of battery voltage to the starter motor, also engaging and disengaging the starter pinion gear with the starter ring gear. This starter motor uses an overrunning clutch and starter pinion gear unit to engage and drive a starter ring gear that is integral to the torque converter or torque converter drive plate mounted on the rear crankshaft flange. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Starting System > Starter Motor > Component Information > Specifications > Page 4251 Starter Motor: Testing and Inspection Correct starter motor operation can be confirmed by performing the following free running bench test.

The starter relay is located in the Power Distribution Center (PDC), in the engine compartment. See the fuse and relay layout label affixed to the inside surface of the PDC cover for starter relay identification and location. The starter relay is a International Standards Organization (ISO) micro-relay. Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal patterns and terminal functions. 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 starter relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION 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 the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Starting System > Starter Relay > Component Information > Locations > Page 4260 Starter Relay: Testing and Inspection STARTER RELAY Starter Relay The starter relay is located in the Power Distribution Center (PDC), in the engine compartment. Refer to the fuse and relay layout label affixed to the underside of the PDC cover for starter relay identification and location. 1. Remove the starter relay from the PDC. Refer to Starter Relay in the Replacement for the procedures. 2. A relay in the 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 the 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 the faulty relay 4. Connect a battery to terminals 85 and 86. There should now be continuity between terminals 30 and 87, and no continuity between terminals 87A and 30. If OK, perform the Relay Circuit Test that follows. If not OK, replace the 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 the open circuit to the fuse in the 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 the common feed terminal (30) in the energized position. This terminal supplies battery voltage to the starter solenoid field coils. There should be continuity between the cavity for relay terminal 87 and the starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair the open circuit to the starter solenoid as required. 4. The coil battery terminal (86) is connected to the electromagnet in the relay It is energized when the ignition switch is held in the START position. Check for battery voltage at the cavity for relay terminal 86 with the ignition switch in the START position, and no voltage when the ignition switch is released to the ON position. If OK, go to Step 5. If not OK, check for an open or short circuit to the ignition switch and repair, if required. If the circuit to the ignition switch is OK, refer to Ignition Switch and Key Lock Cylinder Diagnosis and Testing for testing of the ignition switch. 5. The coil ground terminal (85) is connected to the electromagnet in the relay. It is grounded through the park/neutral position switch only when the gearshift selector lever is in the Park or Neutral positions. Check for continuity to ground at the cavity for relay terminal 85. If not OK, check for an open or short circuit to the park/neutral position switch and repair, if required. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Starting System > Starter Relay > Component Information > Locations > Page 4261 Starter Relay: Service and Repair Power Distribution Center REMOVAL 1.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4274 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4275 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4276 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4277 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4278 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4279 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Page 4291 Auxiliary Power Outlet: Service Precautions WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO RESTRAINT SYSTEMS / AIRBAG SYSTEMS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

MODELS: 1999 (AB) Ram Van 1999 (AN) Dakota 1999 (BR/BE) Ram Truck 1999 (DN) Durango 1999 (TJ) Wrangler 1999 (WJ) Grand Cherokee 1999 (XJ) Cherokee DISCUSSION: Recent quality analysis has revealed an issue with repeated repairs for the same Diagnostic Trouble Code (DTC). The DTC may be due to an overlooked open circuit used to power the component in question. In most instances, either the circuit fuse has been erroneously removed or the fuse itself has an open (blown). The component in question, and its circuit, are often protected by two fuses. It is usually the lower amperage fuse that is either missing or open. The lower amperage fuse is positioned electrically in the circuit between the component in question and either a relay (Auto Shut Down, 02 heater) or the ignition switch. The lower amperage fuse will be located either in the underhood Power Distribution Center (PDC) or in the instrument panel Junction Block. The lower amperage fuse is often missing because it was removed erroneously for use in another low current circuit. If the lower amperage fuse is open (blown), then the circuit and component in question must be checked for an electrical short. Check to make sure that the open fuse was not exchanged with another fuse or was damaged by an installed accessory. NOTE: IF AN OXYGEN SENSOR IS REPLACED, VERIFY THAT THE CIRCUIT FUSE IS GOOD. AN OXYGEN SENSOR HEATER, WHEN DAMAGED OR OVERHEATED, MAY SHORT THE CIRCUIT AND CAUSE THE FUSE TO OPEN (BLOW). The higher amperage fuse should be checked, but is not normally the cause of the DTC. The higher amperage fuse is located in the underhood PDC. It is positioned electrically in the circuit between the battery and either the relay (Auto Shut Down, 02 heater) or the ignition switch. Refer to the applicable Diagnostic Procedures Manual and/or Service Manual (Group 8) for further technical assistance. The following is a list of the components frequently replaced erroneously due to an open fuse. Included are the possible DTC(s) which would be generated as a result. 1).

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4333 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4334 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4335 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4336 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4337 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4338 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4348 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4349 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component

> Diagram Information and Instructions > Page 4375 General Information (Part 2 Of 2) Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content. In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4376 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4377 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4378 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4379 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4380 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4381 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4391 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4392 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Page 4393 Auxiliary Power Outlet: Service Precautions WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO RESTRAINT SYSTEMS / AIRBAG SYSTEMS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

MODELS: 1999 (AB) Ram Van 1999 (AN) Dakota 1999 (BR/BE) Ram Truck 1999 (DN) Durango 1999 (TJ) Wrangler 1999 (WJ) Grand Cherokee 1999 (XJ) Cherokee DISCUSSION: Recent quality analysis has revealed an issue with repeated repairs for the same Diagnostic Trouble Code (DTC). The DTC may be due to an overlooked open circuit used to power the component in question. In most instances, either the circuit fuse has been erroneously removed or the fuse itself has an open (blown). The component in question, and its circuit, are often protected by two fuses. It is usually the lower amperage fuse that is either missing or open. The lower amperage fuse is positioned electrically in the circuit between the component in question and either a relay (Auto Shut Down, 02 heater) or the ignition switch. The lower amperage fuse will be located either in the underhood Power Distribution Center (PDC) or in the instrument panel Junction Block. The lower amperage fuse is often missing because it was removed erroneously for use in another low current circuit. If the lower amperage fuse is open (blown), then the circuit and component in question must be checked for an electrical short. Check to make sure that the open fuse was not exchanged with another fuse or was damaged by an installed accessory. NOTE: IF AN OXYGEN SENSOR IS REPLACED, VERIFY THAT THE CIRCUIT FUSE IS GOOD. AN OXYGEN SENSOR HEATER, WHEN DAMAGED OR OVERHEATED, MAY SHORT THE CIRCUIT AND CAUSE THE FUSE TO OPEN (BLOW). The higher amperage fuse should be checked, but is not normally the cause of the DTC. The higher amperage fuse is located in the underhood PDC. It is positioned electrically in the circuit between the battery and either the relay (Auto Shut Down, 02 heater) or the ignition switch. Refer to the applicable Diagnostic Procedures Manual and/or Service Manual (Group 8) for further technical assistance. The following is a list of the components frequently replaced erroneously due to an open fuse. Included are the possible DTC(s) which would be generated as a result. 1).

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4435 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4436 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4437 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4438 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle.

A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4439 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4440 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4450 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4451 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4452 Fuse Block: Connector Views 8w-12-2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4453 8w-12-4 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4454 8w-12-5 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4455 8w-12-3 Junction Block C1 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4456 Junction Block C2 Junction Block C3 Junction Block C4 Junction Block C5 Junction Block C6 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4457 Junction Block C7 Junction Block C8 Junction Block C9 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4458 Fuse Block: Electrical Diagrams Diagrams 8w-12-6 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4459 8w-12-7 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4460 8w-12-8 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4461 8w-12-9 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4462 8w-12-10 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4463 8w-12-11 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4464 8w-12-12 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4465 8w-12-13 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4466 8w-12-14 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4467 8w-12-15 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4468 8w-12-16 NOTE: To view sheets referred to in these diagrams, see Complete Body and Chassis Diagrams See: Diagrams/Electrical Diagrams/Diagrams By Group Number. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4469 8w-12-2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4470 8w-12-3 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised Alignment: Technical Service Bulletins Steering Wander - Diagnosis and Correction Revised NUMBER: 19-07-00 GROUP: Steering DATE: September 22, 2000 SUBJECT: Steering Wander Diagnosis OVERVIEW: This bulletin provides a diagnostic procedure for steering wander. MODELS: 1998-2001 (AB) Ram Van/Wagon SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight steering corrections are necessary to be able to keep the vehicle moving in a straight line. Steering wander can be created by a number of different conditions including but not limited to the following: ^ Non-factory installed options. ^ Tires or wheels of different size. ^ Aftermarket wheels. ^ Tires that have a belt that has shifted. ^ Incorrect tire pressure. ^ A vehicle that is carrying extra added weight (e.g. tool boxes). ^ Steering and/or suspension components that are worn or damaged. ^ Wheel bearings that are loose, worn, or damaged. ^ A vehicle that is not within alignment specifications. NOTE: UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER. The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering system components are functioning as designed and are not the root cause of steering wander. DIAGNOSIS: 1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to exceed the front or rear Gross Axle Weight Rating (GAWR). 2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to wander and should be replaced before continuing with the diagnosis. 3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove box). NOTE: TIRE PRESSURES ARE NORMALLY SET TO THE LIGHT LOAD SPECIFICATION WHEN PERFORMING STEERING WANDER DIAGNOSIS BUT, ONLY IF THE VEHICLE IS AT CURB OR LIGHT LOAD CONDITIONS. 4. Validate the customer's concern by test driving the vehicle on a smooth highway, free of road crown, ruts, speed bumps, or potholes. Drive the vehicle at speeds between 80 - 113 km/h (50 - 70 mph), preferably without cross wind conditions. If crosswind conditions are prevalent, drive the vehicle in both directions relative to the crosswind. Proceed to the next step if the vehicle exhibits a steering wander condition. NOTE: VEHICLES THAT DO NOT EXHIBIT A STEERING WANDER CONDITION DURING THE ROAD TEST MAY HAVE HAD THE CONDITION CORRECTED WITH STEPS 1-3 OR THE CONDITION MAY HAVE BEEN CAUSED BY ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, ETC.). 5. Raise the vehicle on an appropriate lift. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 4476 6. Secure a dial indicator to the lower control arm. Position the dial indicator so that the tip of the indicator contacts the inside face of the rotor (Figure 1). 7. Place your hands at the top and bottom of the tire/wheel assembly and push the tire/wheel assembly inboard (Figure 2). Zero the dial indicator. With your hands at the top and bottom of the tire/wheel assembly, pull the tire/wheel assembly outboard (Figure 3). Record the dial indicator reading. Perform this procedure on both front wheel bearings and proceed to the next step if the wheel bearing endplay exceeds 0.025 - 0.076 mm (0.001 - 0.003 in.). Proceed to Step 9 if wheel-bearing endplay on both front wheel bearings are within specifications. NOTE: WHEEL BEARING INSPECTION AND ADJUSTMENT IS ONLY REQUIRED ON WHEEL BEARINGS EXCEEDING 0.025 - 0.076 MM (0.001 - 0.003 IN.) ENDPLAY. 8. Remove the wheel bearing protective end cap, cotter pin, nut lock, nut, and washer from the spindle. Inspect the wheel bearings. If it is determined that wheel bearing replacement is necessary, refer to the appropriate Ram Van/Wagon Service Manual, Group 02, Wheel Bearings, for removal and installation information. Reinstall the wheel bearings, washer, and adjustment nut if the wheel bearings pass the inspection. 9. Using a torque wrench, tighten the wheel bearing adjustment nut to 54 N.m (40 ft. lbs.) while rotating the tire/wheel assembly. Stop the wheel from rotating and loosen the nut. Using the procedure identified in Steps 6 and 7 to measure endplay, adjust the front wheel bearing endplay until 0.025 - 0.076 mm (0.001 - 0.003 in.) endplay has been achieved. Install the nut lock and a new cotter pin. 10. Perform the Pre-Alignment inspection as identified in Group 02, Service Procedures, of the appropriate Ram Van/Wagon Service Manual. Any worn steering and/or suspension component must be replaced prior to performing an alignment. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 4477 11. Perform a wheel alignment on the vehicle. Refer to the procedures identified in the appropriate Ram Van/Wagon Service Manual, Group 02, Service Procedures, Wheel Alignment. Adjust any front alignment angle not within specifications. Refer to the chart for proper alignment specifications.

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. - CASTER is the forward or rearward tilt of the steering knuckle from vertical. Tilting the top of the knuckle forward provides negative caster. Tilting the top of the knuckle rearward provides 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. CAUTION: Never attempt to modify suspension or steering components by heating or bending. NOTE: Periodic lubrication of the front suspension/steering system components may be required. Rubber bushings must never be lubricated. Always follow the recommended maintenance schedule. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Page 4480 Alignment: Testing and Inspection Pre-Alignment Inspection Before starting wheel alignment, the following inspection and necessary corrections must be completed. 1. Inspect tires for size and tread wear. 2. Set tire air pressure. 3. Inspect front wheel bearings for wear. 4. Inspect front wheels for excessive radial or lateral runout and balance. 5. Inspect ball studs, linkage pivot points and steering gear for looseness, roughness or binding. 6. Inspect suspension components for wear and noise. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Page 4481 Alignment: Service and Repair The front wheel alignment angles should be set to preferred specifications. This will prevent abnormal tire tread wear. 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. CAMBER AND CASTER Caster & Camber Adjustment Camber and caster angle adjustments involve repositioning the upper suspension arm pivot bar. Alignment adjustments are accomplished by changing the position of the pivot bar. Adjuster Tool 8199 is used to adjust the camber and caster angles. Tools Attached To Frame 1. Clamp the tool on the upper suspension arm frame bracket. Use the two clamp bolts to attach the tool to the bracket. 2. With the adjustment tools installed, loosen both upper suspension arm bolts completely. 3. Tighten or loosen the tool adjustment bolts to move the upper suspension arm inward or outward to obtain the proper camber and caster angles. CASTER: Move the rear position of the pivot bar in or out. This will change the caster angle significantly and camber angle only slightly.

The gear acts as a rolling thread between the worm shaft and rack piston. The worm shaft is supported by a thrust bearing at the lower end and a bearing assembly at the upper end. When the worm shaft is turned the rack piston moves. The rack piston teeth mesh with the pitman shaft. Turning the worm shaft turns the pitman shaft, which turns the steering linkage. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Steering > Steering Gear > Component Information > Specifications > Page 4566 Power Steering Gear Leakage Diagnosis Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Steering > Steering Gear > Component Information > Specifications > Page 4567 Steering Gear: Adjustments CAUTION: Steering gear must be adjusted in the proper order. If adjustments are not performed in order, gear damage and improper steering response may result. NOTE: Adjusting the steering gear in the vehicle is not recommended. Remove gear from the vehicle and drain the fluid. Then mount gear in a vise to perform adjustments. WORM THRUST BEARING PRELOAD 1. Mount the gear carefully into a vise. CAUTION: Do not overtighten the vise on the gear case. This may affect the adjustment. Fig. 8 2. Remove adjuster plug locknut. 3. Rotate the stub shaft back and forth with a 12 point socket to drain the remaining fluid. 4. Turn the adjuster in with Spanner Wrench C-4381. Tighten the plug and thrust bearing in the housing until firmly bottomed in the housing about 34 Nm (25 ft. lbs.).

Rotate adjustment cap back (counterclockwise) with spanner wrench until hole is aligned with the second mark. 8. Install and tighten locknut to 108 Nm (80 ft. lbs.). Be sure adjustment cap does not turn while tightening the locknut. OVER-CENTER NOTE: Before performing this procedure, the worm bearing preload adjustment must be performed. 1. Rotate the stub shaft with a 12 point socket, from stop to stop and count the number of turns. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Steering > Steering Gear > Component Information > Specifications > Page 4569 2. Starting at either stop, turn the stub shaft back 1/2 the total number of turns. This is the center of the gear travel. Checking Over-center Rotation Torque 3. Place the torque wrench in the vertical position on the stub shaft. Rotate the wrench 45 degrees each side of the center and record the highest rotational torque in this range. This is the Over-Center Rotating Torque. NOTE: The stub shaft must rotate smoothly without sticking or binding. 4. Rotate the stud shaft between 90° and 180° to the left of center and record the left off-center preload. Repeat this to the right of center and record the right off-center preload. The average of these two recorded readings is the Preload Rotating Torque. 5. The Over-Center Rotating Torque should be 0.45 - 0.9 Nm (4 - 8 inch lbs.) higher than the Preload Rotating Torque. 6. If an adjustment to the Over-Center Rotating Torque is necessary, first loosen the adjuster lock nut. Then turn the pitman shaft adjuster screw back (COUNTERCLOCKWISE) until fully extended, then turn back in (CLOCKWISE) one full turn. 7. Remeasure Over-Center Rotating Torque. If necessary turn the adjuster screw and repeat measurement until correct Over-Center Rotating Torque is reached. NOTE: To increase the Over-Center Rotating Torque turn the screw CLOCKWISE. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Steering > Steering Gear > Component Information > Specifications > Page 4570 8.

MODELS: 1998-2001 (AB) Ram Van/Wagon SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight steering corrections are necessary to be able to keep the vehicle moving in a straight line. Steering wander can be created by a number of different conditions including but not limited to the following: ^ Non-factory installed options. ^ Tires or wheels of different size. ^ Aftermarket wheels. ^ Tires that have a belt that has shifted. ^ Incorrect tire pressure. ^ A vehicle that is carrying extra added weight (e.g. tool boxes). ^ Steering and/or suspension components that are worn or damaged. ^ Wheel bearings that are loose, worn, or damaged. ^ A vehicle that is not within alignment specifications. NOTE: UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER. The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering system components are functioning as designed and are not the root cause of steering wander. DIAGNOSIS: 1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to exceed the front or rear Gross Axle Weight Rating (GAWR). 2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to wander and should be replaced before continuing with the diagnosis. 3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove box). NOTE: TIRE PRESSURES ARE NORMALLY SET TO THE LIGHT LOAD SPECIFICATION WHEN PERFORMING STEERING WANDER DIAGNOSIS BUT, ONLY IF THE VEHICLE IS AT CURB OR LIGHT LOAD CONDITIONS. 4. Validate the customer's concern by test driving the vehicle on a smooth highway, free of road crown, ruts, speed bumps, or potholes. Drive the vehicle at speeds between 80 - 113 km/h (50 - 70 mph), preferably without cross wind conditions. If crosswind conditions are prevalent, drive the vehicle in both directions relative to the crosswind. Proceed to the next step if the vehicle exhibits a steering wander condition. NOTE: VEHICLES THAT DO NOT EXHIBIT A STEERING WANDER CONDITION DURING THE ROAD TEST MAY HAVE HAD THE CONDITION CORRECTED WITH STEPS 1-3 OR THE CONDITION MAY HAVE BEEN CAUSED BY ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, ETC.). 5. Raise the vehicle on an appropriate lift. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Suspension > Wheel Bearing > Component Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 4663 6. Secure a dial indicator to the lower control arm. Position the dial indicator so that the tip of the indicator contacts the inside face of the rotor (Figure 1). 7. Place your hands at the top and bottom of the tire/wheel assembly and push the tire/wheel assembly inboard (Figure 2). Zero the dial indicator. With your hands at the top and bottom of the tire/wheel assembly, pull the tire/wheel assembly outboard (Figure 3). Record the dial indicator reading. Perform this procedure on both front wheel bearings and proceed to the next step if the wheel bearing endplay exceeds 0.025 - 0.076 mm (0.001 - 0.003 in.). Proceed to Step 9 if wheel-bearing endplay on both front wheel bearings are within specifications. NOTE: WHEEL BEARING INSPECTION AND ADJUSTMENT IS ONLY REQUIRED ON WHEEL BEARINGS EXCEEDING 0.025 - 0.076 MM (0.001 - 0.003 IN.) ENDPLAY. 8. Remove the wheel bearing protective end cap, cotter pin, nut lock, nut, and washer from the spindle. Inspect the wheel bearings. If it is determined that wheel bearing replacement is necessary, refer to the appropriate Ram Van/Wagon Service Manual, Group 02, Wheel Bearings, for removal and installation information. Reinstall the wheel bearings, washer, and adjustment nut if the wheel bearings pass the inspection. 9. Using a torque wrench, tighten the wheel bearing adjustment nut to 54 N.m (40 ft. lbs.) while rotating the tire/wheel assembly. Stop the wheel from rotating and loosen the nut. Using the procedure identified in Steps 6 and 7 to measure endplay, adjust the front wheel bearing endplay until 0.025 - 0.076 mm (0.001 - 0.003 in.) endplay has been achieved. Install the nut lock and a new cotter pin. 10. Perform the Pre-Alignment inspection as identified in Group 02, Service Procedures, of the appropriate Ram Van/Wagon Service Manual. Any worn steering and/or suspension component must be replaced prior to performing an alignment. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Suspension > Wheel Bearing > Component Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 4664 11. Perform a wheel alignment on the vehicle. Refer to the procedures identified in the appropriate Ram Van/Wagon Service Manual, Group 02, Service Procedures, Wheel Alignment. Adjust any front alignment angle not within specifications. Refer to the chart for proper alignment specifications.

The original tire should be repaired or replaced at the first opportunity and reinstall. Do not exceed speeds of 50 MPH. Refer to Owner's Manual for complete details. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Description and Operation Wheels: Description and Operation 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. Fig. 1 All models use stamped steel, cast aluminum or forged aluminum wheels. Every wheel has raised sections between the rim flanges and rim drop well 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Description and Operation > Page 4676 Wheels: Testing and Inspection Inspect wheels for: Excessive run out - Dents or cracks - Damaged wheel lug nut holes - Air Leaks from any area or surface of the rim 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 should 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. USED WHEELS ARE NOT RECOMMENDED. THE SERVICE HISTORY OF THE WHEEL MAY HAVE INCLUDED SEVERE TREATMENT OR VERY HIGH MILEAGE. THE RIM COULD FAIL WITHOUT WARNING. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Description and Operation > Page 4677 Wheels: Service and Repair INSTALLATION The wheel studs and nuts are designed for specific applications. They must be replaced with equivalent parts. Do not use replacement parts of lesser quality or a substitute design. All aluminum and some steel wheels have wheel stud nuts which feature an enlarged nose. This enlarged nose is necessary to ensure proper retention of the aluminum wheels. NOTE: Do not use chrome plated lug nuts with chrome plated wheels. Before installing the wheel, be sure to remove any build up of corrosion on the wheel mounting surfaces. Ensure wheels are installed with good metal-to-metal contact. Improper installation could cause loosening of wheel nuts. This could affect the safety and handling of your vehicle. Lug Nut Tightening Pattern To install the wheel, first position it properly on the mounting surface. All wheel nuts should then be tightened just snug. Gradually tighten them in sequence to the proper torque specification. Never use oil or grease on studs or nuts. Wheels must be replaced if they have: Excessive runout - Bent or dented - Leak air through welds - Have damaged bolt holes - Wheel repairs employing hammering, heating, or welding are not allowed. Original equipment wheels are available through your dealer. Replacement wheels from any other source should be equivalent in: Load carrying capacity - Diameter - Width - Offset - Mounting configuration Failure to use equivalent replacement wheels may affect the safety and handling of your vehicle. Replacement with used wheels is not recommended. Their service history may have included severe treatment. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheel Bearing > Component Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised Wheel Bearing: Technical Service Bulletins Steering Wander - Diagnosis and Correction Revised NUMBER: 19-07-00 GROUP: Steering DATE: September 22, 2000 SUBJECT: Steering Wander Diagnosis OVERVIEW: This bulletin provides a diagnostic procedure for steering wander. MODELS: 1998-2001 (AB) Ram Van/Wagon SYMPTOM/CONDITION: Steering Wander Diagnosis is the diagnosis of a condition where slight steering corrections are necessary to be able to keep the vehicle moving in a straight line. Steering wander can be created by a number of different conditions including but not limited to the following: ^ Non-factory installed options. ^ Tires or wheels of different size. ^ Aftermarket wheels. ^ Tires that have a belt that has shifted. ^ Incorrect tire pressure. ^ A vehicle that is carrying extra added weight (e.g. tool boxes). ^ Steering and/or suspension components that are worn or damaged. ^ Wheel bearings that are loose, worn, or damaged. ^ A vehicle that is not within alignment specifications. NOTE: UNDER CERTAIN ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, CROSSWIND, ETC.), MAY CONTRIBUTE TO STEERING WANDER. The following Steering Wander Diagnosis was developed to ensure that the vehicle and its steering system components are functioning as designed and are not the root cause of steering wander. DIAGNOSIS: 1. Verify that the vehicle is not equipped with non-factory installed options or equipment that may cause the vehicle to wander such as heavy toolboxes or hardware that may cause the vehicle to exceed the front or rear Gross Axle Weight Rating (GAWR). 2. Inspect the condition and size of all tire and wheel assemblies. Tires that are worn or damaged and/or wheels that are of a different size and/or offset than recommended may cause the vehicle to wander and should be replaced before continuing with the diagnosis. 3. Inflate all tires to the pressure specified in the Tire Inflation Pressure sheet (located in the glove box). NOTE: TIRE PRESSURES ARE NORMALLY SET TO THE LIGHT LOAD SPECIFICATION WHEN PERFORMING STEERING WANDER DIAGNOSIS BUT, ONLY IF THE VEHICLE IS AT CURB OR LIGHT LOAD CONDITIONS. 4. Validate the customer's concern by test driving the vehicle on a smooth highway, free of road crown, ruts, speed bumps, or potholes. Drive the vehicle at speeds between 80 - 113 km/h (50 - 70 mph), preferably without cross wind conditions. If crosswind conditions are prevalent, drive the vehicle in both directions relative to the crosswind. Proceed to the next step if the vehicle exhibits a steering wander condition. NOTE: VEHICLES THAT DO NOT EXHIBIT A STEERING WANDER CONDITION DURING THE ROAD TEST MAY HAVE HAD THE CONDITION CORRECTED WITH STEPS 1-3 OR THE CONDITION MAY HAVE BEEN CAUSED BY ROAD CONDITIONS (E.G. HIGH ROAD CROWN, GROOVED ROADS, ETC.). 5. Raise the vehicle on an appropriate lift. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheel Bearing > Component Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 4682 6.

Place your hands at the top and bottom of the tire/wheel assembly and push the tire/wheel assembly inboard (Figure 2). Zero the dial indicator. With your hands at the top and bottom of the tire/wheel assembly, pull the tire/wheel assembly outboard (Figure 3). Record the dial indicator reading. Perform this procedure on both front wheel bearings and proceed to the next step if the wheel bearing endplay exceeds 0.025 - 0.076 mm (0.001 - 0.003 in.). Proceed to Step 9 if wheel-bearing endplay on both front wheel bearings are within specifications. NOTE: WHEEL BEARING INSPECTION AND ADJUSTMENT IS ONLY REQUIRED ON WHEEL BEARINGS EXCEEDING 0.025 - 0.076 MM (0.001 - 0.003 IN.) ENDPLAY. 8. Remove the wheel bearing protective end cap, cotter pin, nut lock, nut, and washer from the spindle. Inspect the wheel bearings. If it is determined that wheel bearing replacement is necessary, refer to the appropriate Ram Van/Wagon Service Manual, Group 02, Wheel Bearings, for removal and installation information. Reinstall the wheel bearings, washer, and adjustment nut if the wheel bearings pass the inspection. 9. Using a torque wrench, tighten the wheel bearing adjustment nut to 54 N.m (40 ft. lbs.) while rotating the tire/wheel assembly. Stop the wheel from rotating and loosen the nut. Using the procedure identified in Steps 6 and 7 to measure endplay, adjust the front wheel bearing endplay until 0.025 - 0.076 mm (0.001 - 0.003 in.) endplay has been achieved. Install the nut lock and a new cotter pin. 10. Perform the Pre-Alignment inspection as identified in Group 02, Service Procedures, of the appropriate Ram Van/Wagon Service Manual. Any worn steering and/or suspension component must be replaced prior to performing an alignment. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheel Bearing > Component Information > Technical Service Bulletins > Steering Wander - Diagnosis and Correction Revised > Page 4683 11.

The blend-air door motor controls the positioning of the blend-air door in the heater-A/C housing. The blend-air door motor is mounted to the top of the right end of the distribution duct under the instrument panel in the passenger compartment. A mechanical link is attached to the end of the blend-air door motor lever in the passenger compartment and passes through a bellows-type boot and a small hole in the dash panel to the engine compartment. In the engine compartment, the link is attached to the end of the blend air door lever on the top cover of the heater-A/C housing. The blend-air door motor is controlled by a potentiometer that is integral to the heater-only or heater-A/C control. The rotary-type temperature control knob positions the potentiometer, and the potentiometer controls the voltage to the blend-air door motor. The blend-air door motor moves the blend-air door based upon the voltage level of the signal received from the potentiometer. The blend-air door motor is accessible for service through the instrument panel glove box opening. The blend-air door motor cannot be repaired and, if faulty or damaged, it must be replaced. The mechanical link and boot are available for service replacement. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Air Door, HVAC > Air Door Actuator / Motor, HVAC > Component Information > Description and Operation > Blend Door Actuator > Page 4702 Air Door Actuator / Motor: Description and Operation Rear Mode Control Motor SYSTEM OPERATION Rear Mode Control Motor Models equipped with the optional rear heater-A/C unit have an electronic rear mode control actuator motor. The two-position rear mode control motor controls the positioning of the heat-A/C mode door in the rear heater-A/C unit housing, and controls the opening and closing of the rear water valve. The rear mode control motor is mounted near the top of the outboard side of the rear heater-A/C unit upper housing, between the horizontal and vertical duct outlets. The output shaft of the rear mode control motor is keyed to an adaptor, which is keyed to the rear heat-A/C mode door pivot shaft. The rear water valve control cable is engaged in a hole on the end of a lever that is integral to the adaptor, and the other end of the cable is secured to the rear water valve control lever. This arrangement links the rear water valve position with the rear heat-A/C mode door position. In the heat position, the rear water valve is open and the rear heater-A/C unit air flow is directed to the left side panel outlets through a horizontal duct. In the A/C position, the rear water valve is closed and the rear heater-A/C unit air flow is directed to the overhead outlets through a vertical duct. The rear mode control motor is controlled by a momentary electrical switch that is integral to the heater-A/C control. When the rotary-type temperature control knob is moved to a position that is at least 80 percent of its travel from the full clockwise or full counterclockwise stop position, the switch opens or closes the signal circuit for the rear mode control motor to ground. This signal causes the rear mode control motor to switch modes. The rear mode control motor is accessible for service by removing the horizontal and vertical ducts from the rear heater-A/C unit. The rear mode control motor cannot be repaired and, if faulty or damaged, it must be replaced. The heat-A/C mode door, the rear water valve, the rear water valve control cable and the adaptor are available for service replacement. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Air Door, HVAC > Air Door Actuator / Motor, HVAC > Component Information > Description and Operation > Page 4703 Air Door Actuator / Motor: Testing and Inspection BLEND - AIR DOOR CONTROL The blend-air door in the heater-A/C housing is controlled by a combination of mechanical linkage and electronic controls.

The blower housing is integral to the recirculation housing, which is secured to the dash panel and the right cowl side inner panel below the heater-A/C housing. The blower motor controls the velocity of air flowing through the heater-A/C system by spinning a squirrel cage-type blower wheel within the housing at the selected speed. The blower motor and blower wheel can be accessed for service from the engine compartment. The front blower motor will only operate when the ignition switch is in the ON position, and when the heater-only or heater-A/C mode control switch knob is in any position, except OFF. The blower motor receives a fused battery feed through the blower motor relay whenever the ignition switch is in the On position. The blower motor battery feed circuit is protected by a fuse in the Power Distribution Center (PDC). The blower motor relay control circuit is protected by a fuse in the junction block. Blower speed is controlled by regulating the blower motor ground path through the heater-A/C mode control switch, the front blower motor switch , the blower motor resistor, and the high speed blower motor relay. When the blower motor switch is placed in the highest speed position it energizes the high speed blower motor relay, which then provides a direct ground feed to the blower motor and bypasses the remainder of the blower motor control circuit. The blower motor and blower motor wheel cannot be repaired and, if faulty or damaged, they must be replaced. The blower motor and blower wheel are each serviced separately. Rear The rear blower motor and blower wheel are located in the optional rear heater-A/C unit housing in the passenger compartment. The rear heater-A/C unit is secured to the floor panel between the fuel filler inlet housing and the left rear wheel house against the left side panel. The blower motor controls the velocity of air flowing through the rear heater- A/C system by spinning a squirrel cage-type blower wheel within the housing at the selected speed. The blower motor and blower wheel can be accessed for service from the passenger compartment. The rear blower motor will only operate when the ignition switch is in the On position. The blower motor receives a fused battery feed through the blower motor relay whenever the ignition switch is in the ON position. The blower motor battery feed circuit is protected by a fuse in the Power Distribution Center (PDC). The blower motor relay control circuit is protected by a fuse in the junction block. Blower speed is controlled by regulating the blower motor ground path through the blower motor switch, the blower motor resistor, and the high speed blower motor relay. When the rear blower motor switch is placed in the highest speed position it energizes the high speed blower motor relay, which then provides a direct ground feed to the blower motor and bypasses the remainder of the blower motor control circuit. The rear blower motor and blower motor wheel cannot be repaired and, if faulty or damaged, they must be replaced. The blower motor and blower wheel are each serviced separately. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Specifications > Page 4743 Blower Motor: Testing and Inspection BLOWER MOTOR WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The electromagnetic coil unit and the hub bearing and pulley assembly are each retained on the nose of the compressor front housing with snap rings. The clutch plate is mounted on the compressor shaft and secured with a nut. These components provide the means to engage and disengage the compressor from the engine serpentine accessory drive belt. When the clutch coil is energized, it magnetically draws the clutch into contact with the 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. The compressor clutch and coil are the only serviced parts on the compressor. The compressor clutch is controlled by several components: the heater-A/C mode control switch, the low pressure cut-off switch, the high pressure cut-off switch, the fin sensing cycling clutch switch, the thermal limiter switch, the compressor clutch relay, and the Powertrain Control Module (PCM). The PCM may delay compressor clutch engagement for up to thirty seconds. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor HVAC > Compressor Clutch > Component Information > Specifications > Page 4794 Compressor Clutch: Service and Repair A/C COMPRESSOR CLUTCH The refrigerant system can remain fully-charged during compressor clutch, pulley, or coil replacement.

Note the alignment of the clutch field coil assembly on the compressor before removing it for correct reinstallation. Clutch / Pulley / Coil Remove/Install Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor HVAC > Compressor Clutch > Component Information > Specifications > Page 4795 11. Remove the snap ring that secures the clutch field coil assembly to the compressor front housing. 12. Remove the clutch field coil assembly from the compressor front housing INSPECTION Examine the friction surfaces of the clutch pulley and the front plate for wear. The pulley and front 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 compressor for oil. If excessive oil is present, the shaft seal is leaking and the compressor must be replaced. Check the clutch pulley bearing for roughness or excessive leakage of grease. Replace the bearing, if required. INSTALLATION 1. Position the back of the clutch field coil against the compressor front housing. Be certain that the locating pin on the back of the coil lines up with the indentation on the compressor front housing. This ensures the proper orientation of the coil and the wire harness. 2. Install the clutch field coil snap ring (bevel side outward) with snap ring pliers. Be certain that the snap ring is properly seated into the groove. CAUTION: If the snap ring is not fully seated in the groove it will vibrate out, resulting in a clutch failure and severe damage to the front housing of the compressor. 3. Install the clutch coil lead wire harness retaining clip on the compressor front housing and tighten the retaining screw. 4. Plug in the compressor clutch wire harness connectors to the thermal limiter switch. 5. Position the clutch pulley assembly onto the compressor. CAUTION: Do not mar or contaminate the clutch pulley friction surface. 6. Install the clutch pulley assembly snap ring (bevel side outward) with snap ring pliers. Be certain that the snap ring is properly seated in the groove. 7. Place a trial stack of shims, 2.54 mm (0.10 in.) thick, on the compressor shaft. Aligning Clutch Plate Splices 8. Note the machined mating splines on the compressor shaft and in the clutch plate hub. 9. Align the mating splines and install the clutch plate on the compressor shaft. 10. Install the external front rotor snap ring with snap ring pliers. The bevel side of the snap ring must be facing outward. Press the snap ring to make sure it is properly seated in the groove. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor HVAC > Compressor Clutch > Component Information > Specifications > Page 4796 Check Clutch Air Gap 11. With the front clutch plate assembly tight against the shims, measure the air gap between the clutch plate and the pulley face with a feeler gauge. The air gap should be from 0.35 to 0.65 mm (0.013 to 0.025 in.). If the proper air gap is not obtained, add or subtract shims until the desired air gap is obtained. 12. Install the compressor shaft nut. Tighten the nut to 14.4 Nm (10.5 ft. lbs.). 13. The shims may compress after tightening the compressor shaft nut. Check the air gap in four or more places to verify that the air gap is still correct. Spin the pulley for a final check. 14. Reverse the remaining removal procedures to complete the installation. Clutch Break-in After a new compressor clutch has been installed, cycle the compressor clutch approximately twenty times (five seconds on, then five seconds off). During this procedure, set the heater-A/C control to the recirculation mode (Max-A/C), the blower motor switch 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor HVAC > Compressor Clutch Coil > Component Information > Testing and Inspection Compressor Clutch Coil: Testing and Inspection COMPRESSOR CLUTCH COIL Testing The battery must be fully-charged before performing the following tests. Refer to Battery for more information. 1. Connect an ammeter (0 to 10 ampere scale) in series with the clutch coil terminal. Use a voltmeter (0 to 20 volt scale) with clip-type leads for measuring the voltage across the battery and the compressor clutch coil. 2. With the heater-A/C mode control switch in any A/C mode and the blower motor switch in the lowest speed position, start the engine and run it at normal idle. 3. The compressor clutch coil voltage should read within two volts of the battery voltage. If there is voltage at the clutch coil, but the reading is not within two volts of the battery voltage, test the clutch coil feed circuit for excessive voltage drop and repair as required. If there is no voltage reading at the clutch coil, use a DRB scan tool and the proper Diagnostic Procedures for testing of the compressor clutch circuit. The following components must be checked and repaired as required before you can complete testing of the clutch coil: - Fuses in the junction block and the Power Distribution Center - Heater-A/C mode control switch - Compressor clutch relay - Fin sensing cycling clutch switch - High pressure cut-off switch - Low pressure cut-off switch - Thermal limiter switch - Powertrain Control Module. 4. The compressor clutch coil is acceptable if the current draw measured at the clutch coil is 2.0 to 3.9 amperes with the electrical system voltage at 11.5 to 12.5 volts. This should only be checked with the work area temperature at 21° C (70° F). If system voltage is more than 12.5 volts, add electrical loads by turning on electrical accessories until the system voltage drops below 12.5 volts. a. If the clutch coil current reading is four amperes or more, the coil is shorted and should be replaced. b. If the clutch coil current reading is zero, the coil is open and should be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Locations > Component Locations Compressor Clutch Relay: Component Locations Power Distribution Center Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Locations > Component Locations > Page 4804 8w-10-2 The compressor clutch relay is located in the Power Distribution Center (PDC) in the engine compartment. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Locations > Component Locations > Page 4805 Compressor Clutch Relay: Connector Locations Power Distribution Center A/C Compressor Clutch Relay Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Description and Operation > A/C Compressor Clutch Relay Description Compressor Clutch Relay: Description and Operation A/C Compressor Clutch Relay Description AIR CONDITIONING (A/C) CLUTCH RELAY The compressor clutch relay is an International Standards Organization (ISO) micro-relay. The terminal designations and functions are the same as a conventional ISO relay. However, the micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay case dimensions are smaller than those of the conventional ISO relay. The compressor clutch relay is a electromechanical device that switches battery current to the compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the relay. The PCM responds to inputs from the heater-A/C mode control switch, the low pressure cut-off switch, the high pressure cut-off switch, and the fin sensing cycling clutch switch. See Compressor Clutch Relay in the Diagnosis and Testing for more information. Power Distribution Center (PDC) Location The compressor clutch relay is located in the Power Distribution Center (PDC) in the engine compartment. Refer to the PDC label for relay identification and location. The compressor clutch relay cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Description and Operation > A/C Compressor Clutch Relay Description > Page 4808 Compressor Clutch Relay: Description and Operation A/C Compressor Clutch Relay-PCM Output AIR CONDITIONING (A/C) CLUTCH RELAY - PCM OUTPUT Power Distribution Center (PDC) Location The A/C relay is located in the Power Distribution Center (PDC). The PDC is located in the engine compartment next to the battery. Refer to label on PDC cover for relay location. The Powertrain Control Module (PCM) activates the A/C compressor through the A/C clutch relay. The PCM regulates A/C compressor operation by switching the ground circuit for the A/C clutch relay on and off. When the PCM receives a request for A/C, it will adjust idle air control (IAC) motor position. This is done to increase idle speed. The PCM will then activate the A/C clutch through the A/C clutch relay. The PCM adjusts IAC stepper motor position to compensate for increased engine load from the A/C compressor. By switching the ground path for the relay on and off, the PCM is able to cycle the A/C compressor clutch. This is based on changes in engine operating conditions. If, during A/C operation, the PCM senses low idle speeds or a wide open throttle condition, it will de-energize the relay. This prevents A/C clutch engagement. The relay will remain de-energized until the idle speed increases or the wide open throttle condition exceeds 15 seconds or no longer exists. The PCM will also de-energize the relay if coolant temperature exceeds 125°C (257°F) or low or high system pressure exists. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Description and Operation > Page 4809 Compressor Clutch Relay: Testing and Inspection COMPRESSOR CLUTCH RELAY Relay Test Compressor Clutch Relay The compressor clutch relay is located in the Power Distribution Center (PDC).

The condenser is a heat exchanger that allows the high-pressure refrigerant gas being discharged by the compressor to give up its heat to the air passing over the condenser fins. When the refrigerant gas gives up its heat, it condenses. When the refrigerant leaves the condenser, it has become a high-pressure liquid refrigerant. The volume of air flowing over the condenser fins is critical to the proper cooling performance of the air conditioning system. Therefore, it is important that there are no objects placed in front of the radiator grille openings in 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 condenser service. The condenser cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Condenser HVAC > Component Information > Specifications > Page 4820 Condenser HVAC: Service and Repair A/C CONDENSER WARNING: REVIEW THE WARNINGS AND CAUTIONS BEFORE PERFORMING THE FOLLOWING OPERATION.

These controls provide the vehicle operator with a number of setting options to help control the climate and comfort within the vehicle. Refer to the owner's manual in the vehicle glove box for more information on the features, use, and suggested operation of these controls. The heater-only or heater-A/C control is located to the right of the instrument cluster and below the radio on the instrument panel. The control panel contains a rotary-type temperature control knob, a rotary-type mode control switch knob, and a rotary-type blower motor speed switch knob. Models with the optional rear heater-A/C unit have a rotary-type rear blower motor speed switch mounted in the accessory switch plate, which is located to the right of the heater-A/C control on the instrument panel. Models with the optional rear heater-A/C unit also have an additional momentary electrical switch that is located within the heater-A/C control. This switch is operated by a cam mechanism that is driven by the temperature control knob. The switch opens and closes a circuit to ground in order to signal the rear mode control motor to change modes. The rear mode control motor controls the rear heat-A/C mode door and the rear water valve. When the temperature control knob is moved to at least 80 percent of its travel from the full counterclockwise (Cool) position, the rear heater-A/C unit is switched to the heat mode and the rear water valve is opened; and, when the temperature control knob is moved to at least 80 percent of its travel from the full clockwise (Warm) position, the rear heater-A/C unit is switched to the A/C mode and the rear water valve is closed. The heater-A/C control unit cannot be repaired. If faulty or damaged, the entire unit must be replaced. The incandescent illumination lamps are available for service replacement. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Testing and Inspection > Heater-A/C Control Assembly Operation Control Assembly: Testing and Inspection Heater-A/C Control Assembly Operation HEATER - A/C CONTROL Satisfactory heater and air conditioner performance depends upon proper operation and adjustment of all operating controls and refrigeration system components. These inspections tests, and adjustments should be used to locate the cause of a malfunction. Operation must be tested as described in the following sequence: 1. Inspect and adjust the serpentine drive belt. Refer to Cooling System for the procedures. 2. Start the engine and set the engine speed to 1300 rpm. 3. Move the temperature control knob to the full counterclockwise (Cool) position and place the mode control knob in the Bi-Level position. The outside (recirculation) air door should be open to outside air. If not OK, see Vacuum System Diagnosis and Testing. See: Heater-A/C Control Assembly Vacuum Test 4. With the temperature control knob in the full counterclockwise (Cool) position, the air being discharged from the outlets should be near ambient temperature. As the temperature control knob is rotated clockwise beyond the third detent, a gradual warming of the air being discharged should be noticed. If OK, go to Step 6. If not OK, go to Step 5. 5. Roll down the glove box from the instrument panel. Refer to Glove Box Roll Down. See: Body and Frame/Interior Moulding / Trim/Glove Compartment/Service and Repair/Glove Box Roll Down Look through the instrument panel glove box opening to locate the blend-air door motor on the top of the distribution duct. While rotating the temperature control knob through its travel, check that the blend-air door motor lever is moving and that the blend-air door link is connected to the lever. If OK, see Heater Performance Diagnosis and Testing. See: Testing and Inspection/Non-Trouble Code Procedures/Heating System Diagnosis If not OK, see Blend-Air Door Control in the Diagnosis and Testing. 6. Open the vehicle windows. Test the blower motor operation in all speeds. If not OK, see the tests for the individual blower motor components. See: Blower Motor Leave the blower motor switch in the highest speed position. 7. On vehicles with air conditioning, the compressor should be running and the air conditioning system in operation. If not OK, see A/C Performance Diagnosis and Testing. See: Testing and Inspection/A/C Performance Testing Mode Control Chart 8. Check the heater-only or heater-A/C mode control switch operation. The systems should respond as shown in the Mode Control chart. Reduce the engine speed to normal idle. The vacuum will be high at low idle and the actuators should respond quickly. If not OK, see Vacuum System - Heater-A/C Controls Diagnosis and Testing. See: Heater-A/C Control Assembly Vacuum Test Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Testing and Inspection > Heater-A/C Control Assembly Operation > Page 4830 9. If the vacuum tests, and the electrical component and circuit tests reveal no problems, disassemble the heater-A/C housing, the recirculation housing and the distribution duct to inspect for mechanical misalignment or binding of the mode doors. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Testing and Inspection > Heater-A/C Control Assembly Operation > Page 4831 Control Assembly: Testing and Inspection Heater-A/C Control Assembly Vacuum Test HEATER - A/C CONTROLS VACUUM TESTING 1. Connect the test set vacuum probe to the heater-A/C vacuum supply (black) tube in the engine compartment. Position the test set gauge so that it can be viewed from the passenger compartment. 2. Place the heater-A/C mode control switch knob in each mode position, one position at a time, and pause after each selection. The test set gauge should return to the 27 kPa (8 in. Hg.) setting shortly after each selection is made. If not OK, a component or vacuum line in the vacuum circuit of the selected mode has a leak. See Locating Vacuum Leaks. See: Testing and Inspection/Non-Trouble Code Procedures/Vacuum System Testing CAUTION: Do not use lubricant on the switch ports or in the holes in the plug, as lubricant will ruin the vacuum valve in the switch.

It is called a combination coil because it combines the functions of a heater core and an evaporator coil into a single heat exchanger unit. The combination coil features six rows of tube and fin construction. The two rows located toward the outboard side of the vehicle serve as the heater core and have engine coolant circulated through them whenever the rear water valve is open. The four rows toward the inboard side of the vehicle serve as the evaporator and have refrigerant circulated through them whenever the air conditioning compressor is operating. The amount of refrigerant flowing through the combination coil is controlled by a dedicated rear thermal expansion valve. The combination coil can be accessed for service by removing the rear heater-A/C unit upper housing. The combination coil cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Evaporator Core > Component Information > Description and Operation > Combination Coil > Page 4875 Evaporator Core: Description and Operation Evaporator Coil SYSTEM OPERATION Combination Coil Models equipped with the optional rear heater-A/C unit have a combination coil located within the rear unit housing.

Evaporator Coil Front The evaporator coil is located in the heater-A/C housing, on the right side of the engine compartment. The evaporator coil is positioned in the heater-A/C housing so that all air that enters the housing must pass over the fins of the evaporator before it is distributed through the system ducts and outlets. However, air passing over the evaporator coil fins will only be conditioned when the compressor is engaged and circulating refrigerant through the evaporator coil tubes. Refrigerant enters the evaporator from the expansion valve as a low-temperature, low-pressure mixture of liquid and gas. As air flows over the fins of the 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 before it leaves the evaporator. The evaporator coil cannot be repaired and, if faulty or damaged, it must be replaced. Rear Models equipped with the optional rear heater-A/C unit have a combination coil located within the rear unit housing. The combination coil functions as both the rear heater core and the rear evaporator coil. See Combination Coil in the Description and Operation for more information. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Evaporator Core > Component Information > Service and Repair > Combination Coil Removal and Installation Evaporator Core: Service and Repair Combination Coil Removal and Installation COMBINATION COIL The combination coil is used only on models with the optional rear heater-A/C unit.

Controlling the evaporator temperature prevents condensate water on the evaporator fins from freezing and obstructing air conditioning system air flow. Fin Sensing Cycling Clutch Switch The fin sensing cycling clutch switch consists of a probe and a switch unit. The probe, which is a Negative Temperature Coefficient (NTC) thermistor in a capillary tube, is inserted between the front evaporator coil fins to monitor evaporator temperature. The switch unit contains internal control logic that monitors the input from the probe in order to switch an internal transistor that controls the output to the PCM. When the fin sensing cycling clutch switch sees a temperature input below about 1.6° C (35° F), it signals the PCM to cycle the compressor OFF. When the temperature input reaches above about 3.9° C (39° F), the switch signals the PCM to cycle the compressor back ON. The fin sensing cycling clutch switch can be accessed for service by removing the screws and carefully lifting the front of the top cover up from the heater-A/C housing. The fin sensing cycling clutch switch is a sealed unit and cannot be adjusted or repaired. If faulty or damaged, the switch must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Fin Sensing Cycling Clutch Switch <--> [Evaporator Temperature Sensor / Switch] > Component Information > Specifications > Page 4886 Fin Sensing Cycling Clutch Switch: Testing and Inspection FIN SENSING CYCLING CLUTCH SWITCH Before testing the fin sensing cycling clutch switch, verify that the refrigerant system has the correct refrigerant charge. Also check that both the low and high pressure cut-off switches are functional, and confirm that the compressor clutch is operational. 1. Turn the ignition switch in the ON position. Place the heater-A/C mode control switch in any A/C position. Check for battery voltage at the fused ignition switch output (Run/Start) circuit cavity of the fin sensing cycling clutch switch wire harness connector. If OK, go to Step 2. If not OK, repair the open circuit to the fuse in the junction block as required. 2. With the ambient temperature between 20 to 30° C (68 to 90° F), start the engine and run the air conditioning system. The compressor clutch should cycle on and off two to three times per minute. If the clutch fails to cycle at this rate in these temperatures, replace the faulty fin sensing cycling clutch switch. NOTE: If the ambient temperature is above 32° C (90° F) the compressor clutch may stay engaged and not cycle due to the high heat load. This condition is normal. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Fin Sensing Cycling Clutch Switch <--> [Evaporator Temperature Sensor / Switch] > Component Information > Specifications > Page 4887 Fin Sensing Cycling Clutch Switch: Service and Repair FIN SENSING CYCLING CLUTCH SWITCH Fin Sensing Cycling Clutch Switch Remove/Install REMOVAL 1.

High-pressure, high temperature liquid refrigerant from the liquid line passes through the expansion valve orifice, converting it into a low- pressure, low-temperature mixture of liquid and gas before it enters the evaporator coil. A temperature sensor in the expansion valve control head monitors the temperature of the refrigerant leaving the evaporator coil through the suction line, and adjusts the orifice size at the liquid line to let the proper amount of refrigerant into the evaporator coil to meet the vehicle cooling requirements. Controlling the refrigerant flow through the evaporator ensures that none of the refrigerant leaving the evaporator is still in a liquid state, which could damage the compressor. The expansion valve is a factory calibrated unit and cannot be adjusted or repaired. If faulty or damaged, the expansion valve must be replaced. Rear Models equipped with the optional rear heater-A/C unit have a second "H" valve-type thermal expansion valve (TXV) installed between the rear unit liquid and suction lines, and the combination coil. High- pressure, high temperature liquid refrigerant from the liquid line passes through the expansion valve orifice, converting it into a low-pressure, low-temperature mixture of liquid and gas before it enters the combination coil.

The discharge pressure (high side) at the service port should reach 966 to 1656 kPa (140 to 240 psi). If this discharge pressure cannot be obtained, check the refrigerant system charge. See Refrigerant System Charging. See: Service and Repair/Refrigerant System Charge WARNING: EXTREME CARE MUST BE USED WHEN HANDLING LIQUID CARBON DIOXIDE (CO2) AS SKIN INJURY CAN OCCUR. PROTECTIVE GLOVES SHOULD BE WORN. 3. Both the front and rear expansion valves should be checked for correct operation. Apply liquid carbon dioxide (CO2) to the front expansion valve control head (completely cover the head) for a minimum of thirty seconds. Remove the rear heater-A/C trim cover and apply liquid carbon dioxide (CO2) to the rear expansion valve control head (completely cover the head) for a minimum of 30 seconds. Grasp the suction line (large line) off the combination coil with a bare hand and hold it for at least two minutes. Use the same procedure with the front expansion valve. Grasp the suction line jumper below the expansion valve (before the rear suction line tee) with a bare hand and hold for at least two minutes. When testing the front expansion valve, place the rear blower motor switch in the Off position. 4. With a correctly operating expansion valve, the suction line will feel warm with the closing of the valve (cold applied). Then the line will cool sharply within two minutes as the valve opens. If this temperature change does not occur, the expansion valve is faulty and must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Expansion Valve > Component Information > Service and Repair > Front Expansion Valve Expansion Valve: Service and Repair Front Expansion Valve FRONT EXPANSION VALVE WARNING: REVIEW THE WARNINGS AND CAUTIONS BEFORE PERFORMING THE FOLLOWING OPERATION.

It is called a combination coil because it combines the functions of a heater core and an evaporator coil into a single heat exchanger unit. The combination coil features six rows of tube and fin construction. The two rows located toward the outboard side of the vehicle serve as the heater core and have engine coolant circulated through them whenever the rear water valve is open. The four rows toward the inboard side of the vehicle serve as the evaporator and have refrigerant circulated through them whenever the air conditioning compressor is operating. The amount of refrigerant flowing through the combination coil is controlled by a dedicated rear thermal expansion valve. The combination coil can be accessed for service by removing the rear heater-A/C unit upper housing. The combination coil cannot be repaired and, if faulty or damaged, it must be replaced. Heater Core Front The heater core is located in the heater-A/C housing, on the right side of the engine compartment. It is a heat exchanger made of rows of tubes and fins. Engine coolant is circulated through heater hoses to the heater core whenever the front water valve is open. As the coolant flows through the heater core, heat removed from the engine is transferred to the heater core fins and tubes. Air directed through the heater core picks up the heat from the heater core fins. The blend air door allows control of the heater output air temperature by controlling how much of the air flowing through the heater-A/C housing is directed through or around the heater core. The blower motor speed controls the volume of air flowing through the heater-A/C system. The heater core cannot be repaired and, if faulty or damaged, it must be replaced. Rear Models equipped with the optional rear heater-A/C unit have a combination coil located within the rear unit housing. The combination coil functions as both the rear heater core and the rear evaporator coil. See Combination Coil above for more information. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Heater Core > Component Information > Service and Repair > Heater Core Removal and Installation Heater Core: Service and Repair Heater Core Removal and Installation Front Heater Core FRONT HEATER CORE REMOVAL 1.

This mechanical valve is designed to vent refrigerant from the system to protect against damage to the compressor and other system components, caused by condenser air flow restriction or an overcharge of refrigerant. The high pressure relief valve vents the system when a discharge pressure of 3445 to 4135 kPa (500 to 600 psi) or above is reached. The valve closes with a minimum discharge pressure of 2756 kPa (400 psi) is reached. The high pressure relief valve vents only enough refrigerant to reduce the system pressure, and then re-seats itself. The majority of the refrigerant is conserved in the system. If the valve vents refrigerant, it does not mean the valve is faulty. On new compressor assemblies, a mylar disc is applied to the venting port of the valve. The disc is primarily intended for protection of the valve during the painting operation. A missing or damaged disc does not indicate failure. If the mylar disc has loosened or come off, apply a drop or two of refrigerant oil into the valve mechanism through the venting holes. This will prevent salt, dirt, or moisture from affecting the operation of the valve. The high pressure relief valve is only serviced as part of the compressor assembly, and must not be removed or otherwise disturbed. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Hose/Line HVAC > Component Information > Specifications > A/C Discharge Hose/Line Hose/Line HVAC: Specifications A/C Discharge Hose/Line Tighten the Compressor mounting screw to 22 Nm (200 in. lbs.).

High pressures are produced in the system when it is operating. Extreme care must be exercised to make sure that all refrigerant system connections are pressure tight. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the hose. Sharp bends will reduce the flow of refrigerant. The flexible hose lines should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold. It is a good practice to inspect all flexible refrigerant system hose lines at least once a year to make sure they are in good condition and properly routed. There are two types of refrigerant fittings: - All fittings with O-rings need to be coated with refrigerant oil before installation. Use only O-rings that are the correct size and approved for use with R-134a refrigerant. Failure to do so may result in a leak. - Unified plumbing connections with gaskets cannot be serviced with O-rings. The gaskets are not reusable and new gaskets do not require lubrication before installing. Using the proper tools when making a refrigerant plumbing connection is very important. Improper tools or improper use of the tools can damage the refrigerant fittings. Always use two wrenches when loosening or tightening tube fittings. Use one wrench to hold one side of the connection stationary while loosening or tightening the other side of the connection with a second wrench. The refrigerant must be recovered completely from the system before opening any fitting or connection. Open the fittings with caution, even after the refrigerant has been recovered. If any pressure is noticed as a fitting is loosened, tighten the fitting and recover the refrigerant from the system again. Do not discharge refrigerant into the atmosphere. Use an R-134a refrigerant recovery/recycling device that meets SAE Standard J2210. The refrigerant system will remain chemically stable as long as pure, moisture-free R-134a refrigerant and refrigerant oil is used. Dirt, moisture, or air can upset this chemical stability Operational troubles or serious damage can occur if foreign material is present in the refrigerant system. When it is necessary to open the refrigerant system, have everything needed to service the system ready. The refrigerant system should not be left open to the atmosphere any longer than necessary Cap or plug all lines and fittings as soon as they are opened to prevent the entrance of dirt and moisture. All lines and components in parts stock should be capped or sealed until they are to be installed. All tools, including the refrigerant recycling equipment, the manifold gauge set, and test hoses should be kept clean and dry. All tools and equipment must be designed for R-134a refrigerant. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Hose/Line HVAC > Component Information > Specifications > Page 4926 Hose/Line HVAC: Description and Operation Refrigerant Hoses/Lines/Tubes Precautions Kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire system.

SYSTEM OPERATION Refrigerant Line The refrigerant lines and hoses are used to carry the refrigerant between the various air conditioning system components. A barrier hose design with a nylon tube inner hose liner is used for the R-134a air conditioning system on this vehicle. This nylon liner helps to further contain the R-134a refrigerant, which has a smaller molecular structure than R-12 refrigerant. The ends of the refrigerant hoses are made from lightweight aluminum or steel, and use braze-less fittings. Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system. Kinks and sharp bends reduce the flow of refrigerant in the system. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the hose. In addition, the flexible hose refrigerant lines should be routed so they are at least 80 mm (3 inches) from the exhaust manifold. High pressures are produced in the refrigerant system when the air conditioning 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 with other components of the HVAC system with peanut-block style fittings. A status seal type flat steel gasket with a captured compressible O-ring, is used to mate plumbing lines with A/C 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. Low Pressure Gauge Hose The low pressure hose (Blue with Black stripe) attaches to the suction service port. This port is located on the suction line jumper, near the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Hose/Line HVAC > Component Information > Specifications > Page 4927 filter-drier at the front of the engine compartment. High Pressure Gauge Hose The high pressure hose (Red with Black stripe) attaches to the discharge service port. This port is located on the discharge line between the compressor and the condenser, near the front of the engine compartment. Recovery/Recycling/Evacuation/Charging Hose The center manifold hose (Yellow, or White, with Black stripe) is used to recover, evacuate, and charge the refrigerant system. When the low or high pressure valves on the manifold gauge set are opened, the refrigerant in the system will escape through this hose. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Hose/Line HVAC > Component Information > Service and Repair > A/C Discharge Hose/Line Replacement Hose/Line HVAC: Service and Repair A/C Discharge Hose/Line Replacement A/C SUCTION AND DISHARGE LINE Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system.

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 air conditioning system. Even a small amount of R-12 added to an R-134a refrigerant system will cause compressor failure, refrigerant oil sludge or poor air conditioning 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 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 compressor identifying to service technicians that the air conditioning system is equipped with R-134a. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Refrigerant Filter > Component Information > Specifications > Mechanical Specifications Refrigerant Filter: Mechanical Specifications Tighten the suction line jumper block fitting mounting screw to 13.5 Nm (120 in. lbs.).

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. The TR-105 compressor used in this vehicle is designed to use an SP-15 PAG refrigerant oil. Use only refrigerant oil of this same type to service the refrigerant system. 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 compressor damage, and too much can reduce air conditioning system performance. PAG refrigerant oil is much 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Refrigerant Oil > Component Information > Specifications > Page 4982 Refrigerant Oil: Service and Repair Refrigerant Oil Level When an air conditioning system is assembled at the factory, all components except the compressor and the combination coil, if the vehicle is so equipped, are refrigerant oil free. After the refrigerant system has been charged and operated, the refrigerant oil in the compressor and the combination coil is dispersed throughout the refrigerant system. The combination coil, evaporator, filter-drier, condenser, and compressor will each retain a significant amount of the needed refrigerant oil. It is important to have the correct amount of oil in the refrigerant system. This ensures proper lubrication of the compressor. Too little oil will result in damage to the compressor. Too much oil will reduce the cooling capacity of the air conditioning system. It will not be necessary to check the oil level in the 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 ml (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 Chart Refrigerant oil must be added when a filter-drier, evaporator coil, combination coil, or condenser are replaced. See the Refrigerant Oil Capacities chart. When a compressor is replaced, the refrigerant oil must be drained from the old compressor and measured. Drain all of the refrigerant oil from the new compressor, then fill the new compressor with the same amount of refrigerant oil that was drained out of the old compressor. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Refrigerant Pressure Sensor / Switch, HVAC > High Pressure Sensor / Switch, HVAC > Component Information > Specifications High Pressure Sensor / Switch: Specifications Tighten the high pressure cut-off switch to 7.5 Nm (5.5 ft. lbs.). Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Refrigerant Pressure Sensor / Switch, HVAC > High Pressure Sensor / Switch, HVAC > Component Information > Specifications > Page 4987 High Pressure Sensor / Switch: Locations High Pressure Cut-Off Switch Remove/Install The high pressure cut-off switch is located on the discharge line near the condenser. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Refrigerant Pressure Sensor / Switch, HVAC > High Pressure Sensor / Switch, HVAC > Component Information > Specifications > Page 4988 High Pressure Sensor / Switch: Description and Operation High Pressure Cut-off Switch High Pressure Cut-Off Switch Remove/Install The high pressure cut-off switch is located on the discharge line near the condenser. The switch is screwed onto a fitting that contains a Schrader-type valve, which allows the switch to be serviced without discharging the refrigerant system. The discharge line fitting is equipped with an O-ring to seal the switch connection. The high pressure cut-off switch is connected in series electrically with the low pressure cut-off switch between the fin sensing cycling clutch switch and the Powertrain Control Module (PCM). The switch contacts open and close causing the PCM to turn the compressor clutch on and off. This prevents compressor operation when the discharge line pressure approaches high levels. The high pressure cut-off switch contacts are open when the discharge line pressure rises above about 3100 to 3375 kPa (450 to 490 psi). The switch contacts will close when the discharge line pressure drops to about 1860 to 2275 kPa (270 to 330 psi). The high pressure cut-off switch is a factory-calibrated unit.

The terminal designations and functions are the same as a conventional ISO relay. However, the micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay case dimensions are smaller than those of the conventional ISO relay. The compressor clutch relay is a electromechanical device that switches battery current to the compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the relay. The PCM responds to inputs from the heater-A/C mode control switch, the low pressure cut-off switch, the high pressure cut-off switch, and the fin sensing cycling clutch switch. See Compressor Clutch Relay in the Diagnosis and Testing for more information. Power Distribution Center (PDC) Location The compressor clutch relay is located in the Power Distribution Center (PDC) in the engine compartment. Refer to the PDC label for relay identification and location. The compressor clutch relay cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Relays and Modules - HVAC > Compressor Clutch Relay > Component Information > Description and Operation > A/C Compressor Clutch Relay Description > Page 5028 Compressor Clutch Relay: Description and Operation A/C Compressor Clutch Relay-PCM Output AIR CONDITIONING (A/C) CLUTCH RELAY - PCM OUTPUT Power Distribution Center (PDC) Location The A/C relay is located in the Power Distribution Center (PDC). The PDC is located in the engine compartment next to the battery. Refer to label on PDC cover for relay location. The Powertrain Control Module (PCM) activates the A/C compressor through the A/C clutch relay. The PCM regulates A/C compressor operation by switching the ground circuit for the A/C clutch relay on and off. When the PCM receives a request for A/C, it will adjust idle air control (IAC) motor position. This is done to increase idle speed. The PCM will then activate the A/C clutch through the A/C clutch relay. The PCM adjusts IAC stepper motor position to compensate for increased engine load from the A/C compressor. By switching the ground path for the relay on and off, the PCM is able to cycle the A/C compressor clutch. This is based on changes in engine operating conditions. If, during A/C operation, the PCM senses low idle speeds or a wide open throttle condition, it will de-energize the relay. This prevents A/C clutch engagement. The relay will remain de-energized until the idle speed increases or the wide open throttle condition exceeds 15 seconds or no longer exists. The PCM will also de-energize the relay if coolant temperature exceeds 125°C (257°F) or low or high system pressure exists. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Relays and Modules - HVAC > Compressor Clutch Relay > Component Information > Description and Operation > Page 5029 Compressor Clutch Relay: Testing and Inspection COMPRESSOR CLUTCH RELAY Relay Test Compressor Clutch Relay The compressor clutch relay is located in the Power Distribution Center (PDC).

Controlling the evaporator temperature prevents condensate water on the evaporator fins from freezing and obstructing air conditioning system air flow. Fin Sensing Cycling Clutch Switch The fin sensing cycling clutch switch consists of a probe and a switch unit. The probe, which is a Negative Temperature Coefficient (NTC) thermistor in a capillary tube, is inserted between the front evaporator coil fins to monitor evaporator temperature. The switch unit contains internal control logic that monitors the input from the probe in order to switch an internal transistor that controls the output to the PCM. When the fin sensing cycling clutch switch sees a temperature input below about 1.6° C (35° F), it signals the PCM to cycle the compressor OFF. When the temperature input reaches above about 3.9° C (39° F), the switch signals the PCM to cycle the compressor back ON. The fin sensing cycling clutch switch can be accessed for service by removing the screws and carefully lifting the front of the top cover up from the heater-A/C housing. The fin sensing cycling clutch switch is a sealed unit and cannot be adjusted or repaired. If faulty or damaged, the switch must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Sensors and Switches - HVAC > Fin Sensing Cycling Clutch Switch <--> [Evaporator Temperature Sensor / Switch] > Component Information > Specifications > Page 5047 Fin Sensing Cycling Clutch Switch: Testing and Inspection FIN SENSING CYCLING CLUTCH SWITCH Before testing the fin sensing cycling clutch switch, verify that the refrigerant system has the correct refrigerant charge. Also check that both the low and high pressure cut-off switches are functional, and confirm that the compressor clutch is operational. 1. Turn the ignition switch in the ON position. Place the heater-A/C mode control switch in any A/C position. Check for battery voltage at the fused ignition switch output (Run/Start) circuit cavity of the fin sensing cycling clutch switch wire harness connector. If OK, go to Step 2. If not OK, repair the open circuit to the fuse in the junction block as required. 2. With the ambient temperature between 20 to 30° C (68 to 90° F), start the engine and run the air conditioning system. The compressor clutch should cycle on and off two to three times per minute. If the clutch fails to cycle at this rate in these temperatures, replace the faulty fin sensing cycling clutch switch. NOTE: If the ambient temperature is above 32° C (90° F) the compressor clutch may stay engaged and not cycle due to the high heat load. This condition is normal. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Sensors and Switches - HVAC > Fin Sensing Cycling Clutch Switch <--> [Evaporator Temperature Sensor / Switch] > Component Information > Specifications > Page 5048 Fin Sensing Cycling Clutch Switch: Service and Repair FIN SENSING CYCLING CLUTCH SWITCH Fin Sensing Cycling Clutch Switch Remove/Install REMOVAL 1.

When diagnosing any airbag squib circuit Diagnostic Trouble Code (DTC) with a DRBIII(R), the use of the Airbag Load Tool (Special Tool 8310 and 8443) is required. The Airbag Load Tool, used in conjunction with the DRBIII(R) are used to isolate and test components and wiring for failure. Only replace the component or wiring that has failed. This will reduce unnecessary cost to the customer or DaimlerChrysler. NOTE: AIRBAG REPLACEMENT IS NOT REQUIRED EVERY TIME IT IS REMOVED OR WHEN ANOTHER COMPONENT HAS FAILED. USE OF THE DRBIII(R) AND AIRBAG LOAD TOOL WILL DETERMINE IF THE AIRBAG HAS FAILED AND REPLACEMENT IS NEEDED.

Clock Springs Recent analysis of returned clock springs have indicated that prior service may have contributed to the clock spring's failure. ^ Do not use silicone or any other lubricant spray on or near the clock spring. Lubricants are often used in the clock spring area of the steering column to eliminate noise. Lubricants may have an adverse effect on the clock spring. ^ Clock spring centering. Any repair that may disrupt the positioning of the steering wheel with the front wheels will require that the clock spring be centered. This includes clock spring replacement, steering column service, HVAC service, steering gear service, and front suspension crossmember service. Refer to the appropriate Service Manual for the clock spring centering procedure.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Diagram Information and Instructions > Page 5109 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Diagram Information and Instructions > Page 5110 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Diagram Information and Instructions > Page 5111 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Diagram Information and Instructions > Page 5112 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Diagram Information and Instructions > Page 5113 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Diagram Information and Instructions > Page 5114 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number for the subsequent diagram will match a listed group shown. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Diagram Information and Instructions > Page 5115 Connector and Terminal Replacement 1.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Diagram Information and Instructions > Page 5124 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Diagram Information and Instructions > Page 5125 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Diagram Information and Instructions > Page 5126 Air Bag: Connector Views Driver Airbag Squib Passenger Airbag Jumper Passenger Airbag Jumper (w/o On/Off Switch) Passenger Airbag Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Diagram Information and Instructions > Page 5127 Air Bag: Electrical Diagrams Airbag System Airbag System With On/Off Switch Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Diagrams > Page 5128 Air Bag: Description and Operation DRIVER SIDE AIRBAG MODULE Description The driver side airbag module protective trim cover is the most visible part of the driver side airbag system. The driver side airbag module is mounted directly to the steering wheel. Located under the airbag module trim cover are the horn switch, the folded airbag cushion, and the airbag cushion supporting components. The resistive membrane-type horn switch is secured with heat stakes to the inside surface of the airbag module trim cover, between the trim cover and the folded airbag cushion. The driver side airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The driver side airbag module trim cover and the horn switch are available as a unit for service replacement. Operation The driver side airbag module includes a stamped metal housing to which the cushion and an inflator unit are attached and sealed. The conventional pyrotechnic-type inflator assembly is mounted to studs on the back of the airbag module housing. The inflator seals the hole in the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. Following an airbag deployment, the airbag cushion quickly deflates by venting this gas towards the instrument panel through the porous fabric material used on the steering wheel side of the airbag cushion. The protective trim cover is fitted to the front of the airbag module and forms a decorative cover in the center of the steering wheel. The inside of the trim cover has locking blocks molded into it that engage a lip on the airbag module metal housing. Two stamped metal retainers then fit over the inflator mounting studs on the back of the airbag module housing and are engaged in slots on the inside of the securely locking the trim cover into place. The trim cover will split at predetermined breakout lines, then fold back out of the way along with the horn switch upon airbag deployment. PASSENGER SIDE AIRBAG MODULE Description The passenger side airbag door on the instrument panel above the glove box is the most visible part of the passenger side airbag system. Located under the airbag door are the passenger side airbag cushion and the airbag cushion supporting components. The passenger side airbag module includes an extruded aluminum housing within which the cushion and inflator are mounted and sealed. The airbag housing extrusion also includes two flanges and two channels. The flanges, one at the front and one at the rear, serve as the mounting brackets for the module. The two channels, one near the upper rear of the housing and one near the lower rear, are used to secure the passenger side airbag door to the module. Two stamped metal brackets, one on each end of the housing, enclose the cushion and inflator and also serve to lock the passenger side airbag door flanges into the upper and lower channels of the module housing. Following a passenger side airbag deployment, the passenger side airbag module and the airbag door must be replaced. The passenger side airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The passenger side airbag door is available as a separate service item. Operation The hybrid-type inflator assembly includes a small canister of highly compressed argon gas. The inflator seals the hole in the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. Following an airbag deployment, the airbag cushion quickly deflates by venting this gas through the porous fabric material used on each end panel of the airbag cushion. The passenger side airbag module front bracket is secured beneath the instrument panel top pad with screws to the instrument panel structural support. The rear bracket is secured with screws to the upper glove box opening reinforcement. The molded plastic airbag door is secured to the airbag module by beaded upper and lower mounting flanges and also to the instrument panel base trim with five molded snap features. The airbag door has predetermined breakout lines concealed beneath its decorative cover. Upon airbag deployment, the airbag door will split at the breakout lines and the door will pivot out of the way. CAUTION: THE AIRBAG MODULE INFLATOR ASSEMBLY CONTAINS SODIUM AZIDE AND POTASSIUM NITRATE. THESE MATERIALS ARE POISONOUS AND EXTREMELY FLAMMABLE. CONTACT WITH ACID, WATER, OR HEAVY METALS MAY PRODUCE HARMFUL AND IRRITATING GASES (SODIUM HYDROXIDE IS FORMED IN THE PRESENCE OF MOISTURE) OR COMBUSTIBLE COMPOUNDS, IN ADDITION, THE PASSENGER AIRBAG MODULE CONTAINS ARGON GAS PRESSURIZED TO OVER 2500 PSI. DO NOT ATTEMPT TO DISMANTLE AN AIRBAG MODULE OR TAMPER WITH ITS INFLATOR. DO NOT PUNCTURE, INCINERATE, OR BRING INTO CONTACT WITH ELECTRICITY DO NOT STORE AT TEMPERATURE EXCEEDING 93 ° C (200 °F). Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Service and Repair > Airbag System Service Air Bag: Service and Repair Airbag System Service NON-DEPLOYED At no time should any source of electricity be permitted near the inflator on the back of an airbag module. when carrying a non-deployed airbag module, the trim cover or airbag side of the module should be pointed away from the body to minimize injury in the event of an accidental deployment. If the module is placed on a bench or any other surface, the trim cover or airbag side of the module should be face up to minimize movement in the event of an accidental deployment. In addition, the airbag system should be disarmed whenever any steering wheel, steering column, or instrument panel components require diagnosis or service. Failure to observe this warning could result in accidental airbag deployment and possible personal injury. Refer to Instrument Panel Systems for additional service procedures on the instrument panel components. DISPOSAL OF NON-DEPLOYED AIRBAG MODULES All damaged or faulty and non-deployed driver side or passenger side airbag modules which are replaced on vehicles are to be returned. If an airbag module assembly is faulty or damaged and non-deployed, refer to the parts return list in the current Chrysler Corporation Warranty Policies and Procedures for the proper handling and disposal procedures. DEPLOYED Any vehicle which is to be returned to use after an airbag deployment, must have both airbag modules and the clockspring replaced. These components will be damaged or weakened as a result of an airbag deployment, which may or may not be obvious during a visual inspection, and are not intended for reuse. In addition, the steering column may incur damage during an airbag deployment, which may not be obvious during a visual inspection. Other vehicle components should be closely inspected, but are to be replaced only as required by the extent of the visible damage incurred. STORAGE An airbag module must be stored in its original, special container until used for service. Also, it must be stored in a clean, dry environment; away from sources of extreme heat, sparks, and high electrical energy. Always place or store an airbag module on a surface with its trim cover or airbag side facing up, to minimize movement in case of an accidental deployment. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Service and Repair > Airbag System Service > Page 5131 Air Bag: Service and Repair Cleanup Procedure Wear Safety Glasses And Rubber Gloves - Typical Following an airbag system deployment, the vehicle interior will contain a powdery residue. This residue consists primarily of harmless particulate by-products of the small pyrotechnic charge used to initiate the airbag deployment propellant. However, this residue will also contain traces of sodium hydroxide powder, a chemical by-product of the propellant material that is used to generate the nitrogen gas that inflates the airbag. Since sodium hydroxide powder can irritate the skin, eyes, nose, or throat, be sure to wear safety glasses, rubber gloves, and a long-sleeved shirt during cleanup. WARNING: 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. Begin the cleanup by removing the airbag modules from the vehicle. Refer to Driver Side Airbag Module and Passenger Side Airbag Module in the Replacement for the procedures. Use 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. Vacuum Heater And A/C Outlets - Typical Be sure 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. You may need to vacuum the interior of the vehicle a second time to recover all of the powder.

The ACM contains an electronic microprocessor, an electronic impact sensor, an electromechanical safing sensor, and an energy storage capacitor. The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. OPERATION The microprocessor in the ACM contains the airbag system logic. The airbag system logic includes On-Board Diagnostics (OBD), and the ability to communicate with the instrument cluster circuitry over the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor continuously monitors all of the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster over the CCD data bus to turn on the airbag indicator lamp. Refer to instrument Cluster in the Instrument Panel Systems for more information on the airbag indicator lamp. One electronic impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate as signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbags. In addition to the electronic impact sensor, there is an electromechanical sensor within the ACM called a safing sensor. The safing sensor is a normally open series switch located in the airbag deployment circuit of the ACM. This sensor detects impact energy of a lesser magnitude than the electronic impact sensor, and must be closed in order for the airbags to deploy. The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags for up to one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact, if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag Control Module > Component Information > Specifications > Page 5151 Air Bag Control Module: Service and Repair WARNING: - THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG.

This switch, which is located on the instrument panel, allows the passenger side airbag system to be disabled when certain child restraint devices are being used in the right front seating position. The passenger side airbag on/off switch is equipped with a key actuator so that the switch position can only be changed using an ignition key. When the ignition switch is in the On position and the passenger side airbag system is disabled, a Light-Emitting Diode (LED) illuminates an Off indicator lamp on the face plate of the switch. The passenger side airbag on/off switch cannot be adjusted or repaired and, if faulty or damaged, the switch assembly must be replaced. Operation To actuate the passenger side airbag on/off switch, insert the ignition key in the switch key actuator. The switch key actuator is then rotated with the ignition key to its clockwise stop (the key actuator slot will be aligned with the Off indicator lamp) to disable the passenger side airbag system. When the switch key actuator is rotated with the ignition key to its counterclockwise stop (the key actuator slot will be in a vertical position), the Off indicator lamp will be extinguished and the passenger side airbag system will be enabled. The ON/OFF switch cannot be adjusted or repaired and, if faulty or damaged, the ON/OFF switch must be replaced. WARNING: THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER SIDE AIRBAG ON/OFF SWITCH KEY ACTUATOR AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE SWITCH KEY ACTUATOR.

Clock Springs Recent analysis of returned clock springs have indicated that prior service may have contributed to the clock spring's failure. ^ Do not use silicone or any other lubricant spray on or near the clock spring. Lubricants are often used in the clock spring area of the steering column to eliminate noise. Lubricants may have an adverse effect on the clock spring. ^ Clock spring centering. Any repair that may disrupt the positioning of the steering wheel with the front wheels will require that the clock spring be centered. This includes clock spring replacement, steering column service, HVAC service, steering gear service, and front suspension crossmember service. Refer to the appropriate Service Manual for the clock spring centering procedure.

The clockspring is used to maintain a continuous electrical circuit between the fixed clockspring wire harness on the steering column and several electrical components that rotate with the steering wheel. The rotating components include the driver side airbag module and, if the vehicle is so equipped, the vehicle speed control switches. The clockspring cannot be repaired. If the clockspring is faulty, damaged, or if the driver side airbag has been deployed, the clockspring must be replaced. OPERATION The clockspring assembly consists of a plastic case which contains a flat, ribbon-like, electrically conductive tape that winds and unwinds like a clockspring with the steering wheel rotation. The electrically conductive tape consists of several fine gauge copper wire leads sandwiched between two narrow strips of plastic film. Like the clockspring in a timepiece, the clockspring tape has travel limits and can be damaged by being wound too tightly 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 other steering components so that it can operate within its designed travel limits. However, if the clockspring is removed for service or if the steering column is disconnected from the steering gear allowing the clockspring tape to change position relative to the other steering components, it must be re-centered following completion of the service or it may be damaged. Refer to Clockspring Centering in the Adjustments for the proper centering procedures. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Clockspring Assembly / Spiral Cable, Air Bag > Component Information > Technical Service Bulletins > Page 5187 Clockspring Assembly / Spiral Cable: Adjustments The clockspring is designed to wind and unwind when the steering wheel is rotated, but is only designed to rotate the same number of turns (about five complete rotations) as the steering wheel can be turned from stop to stop. Centering the clockspring indexes the clockspring tape to other steering components so that it can operate within its designed travel limits. The rotor of a centered clockspring can be rotated two and one-half turns in either direction from the centered position, without damaging the clockspring tape. However, if the clockspring is removed for service or if the steering column is disconnected from the steering gear, the clockspring tape can change position relative to the other steering components. The clockspring must then be re-centered following completion of the service or the clockspring tape may be damaged. WARNING: THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT.

The ACM contains an electronic microprocessor, an electronic impact sensor, an electromechanical safing sensor, and an energy storage capacitor. The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. OPERATION The microprocessor in the ACM contains the airbag system logic. The airbag system logic includes On-Board Diagnostics (OBD), and the ability to communicate with the instrument cluster circuitry over the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor continuously monitors all of the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster over the CCD data bus to turn on the airbag indicator lamp. Refer to instrument Cluster in the Instrument Panel Systems for more information on the airbag indicator lamp. One electronic impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate as signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbags. In addition to the electronic impact sensor, there is an electromechanical sensor within the ACM called a safing sensor. The safing sensor is a normally open series switch located in the airbag deployment circuit of the ACM. This sensor detects impact energy of a lesser magnitude than the electronic impact sensor, and must be closed in order for the airbags to deploy. The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags for up to one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact, if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Relays and Modules - Restraint Systems > Air Bag Control Module > Component Information > Specifications > Page 5218 Air Bag Control Module: Service and Repair WARNING: - THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG.

This is the only sure way to disable the airbag system. failure to do this could result in accidental airbag deployment and possible personal injury. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Seat Belt Systems > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Air Bag Disarming > Page 5224 Air Bag(s) Arming and Disarming: Service and Repair Air Bag Arming Air Bag Arming 16-Way Data Link Connector - Typical A DRB scan tool is required for diagnosis of the airbag system. See the proper Diagnostic Procedures for more information. 1. Connect the DRB scan tool to the 16-way data link wire harness connector. The connector is located on the driver side lower edge of the instrument panel, below the steering column. 2. Exit the vehicle with the DRB. Be certain that the DRB contains the latest version of the proper DRB software. 3. Connect the negative battery terminal. 4. From outside of the vehicle (away from the airbags in case of an accidental deployment) turn the ignition switch to the ON position 5. Using the DRB, read and record the active Diagnostic Trouble Code (DTC) data. 6. Read and record any stored DTC data. 7. See the proper Diagnostic Procedures if any DTC's are found. 8. After completing the necessary repairs, try to erase the stored DTC data. If any problems remain, the stored DTC data will not erase. See the proper Diagnostic Procedures for the procedures to diagnose any stored DTC that will not erase. 9. With the ignition switch still in the On position, check to be certain that nobody is in the vehicle. 10. From outside of the vehicle (away from the airbags in case of an accidental deployment) turn the ignition switch to the OFF position for about ten seconds, and then back to the ON position. Observe the airbag indicator lamp in the instrument cluster. It should light for six to eight seconds, and then go out. This indicates that the airbag system is functioning normally. NOTE: If the airbag indicator lamp fails to light, or lights and stays on, there is an airbag system malfunction. See the proper Diagnostic Procedures to diagnose the problem. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Restraint Systems > Seat Belt Systems > Child Restraint > Child Seat Tether Attachment > Component Information > Technical Service Bulletins > Restraints - Child Seat Tether Installation Child Seat Tether Attachment: Technical Service Bulletins Restraints - Child Seat Tether Installation NUMBER: 23-029-08 GROUP: Body DATE: October 24, 2008 THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 23-08-00 REV.

This switch, which is located on the instrument panel, allows the passenger side airbag system to be disabled when certain child restraint devices are being used in the right front seating position. The passenger side airbag on/off switch is equipped with a key actuator so that the switch position can only be changed using an ignition key. When the ignition switch is in the On position and the passenger side airbag system is disabled, a Light-Emitting Diode (LED) illuminates an Off indicator lamp on the face plate of the switch. The passenger side airbag on/off switch cannot be adjusted or repaired and, if faulty or damaged, the switch assembly must be replaced. Operation To actuate the passenger side airbag on/off switch, insert the ignition key in the switch key actuator. The switch key actuator is then rotated with the ignition key to its clockwise stop (the key actuator slot will be aligned with the Off indicator lamp) to disable the passenger side airbag system. When the switch key actuator is rotated with the ignition key to its counterclockwise stop (the key actuator slot will be in a vertical position), the Off indicator lamp will be extinguished and the passenger side airbag system will be enabled. The ON/OFF switch cannot be adjusted or repaired and, if faulty or damaged, the ON/OFF switch must be replaced. WARNING: THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER SIDE AIRBAG ON/OFF SWITCH KEY ACTUATOR AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE SWITCH KEY ACTUATOR.

The antenna mast has a spiral groove cut down its length to reduce wind noise. The antenna mast is connected to the center wire of the coaxial antenna cable, and is not grounded to any part of the vehicle. To eliminate static, the antenna base must have a good ground. The coaxial antenna cable shield (the outer wire mesh of the cable) is grounded to the antenna base and the radio receiver chassis. The antenna coaxial cable has an additional disconnect, located on the outboard side of the right instrument panel end bracket and concealed by the right instrument panel end cap. This additional disconnect allows the instrument panel assembly to be removed and installed without removing the radio receiver. The factory-installed Electronically Tuned Radios (ETR) automatically compensate for radio antenna trim. Therefore, no antenna trimmer adjustment is required or possible when replacing the radio receiver or the antenna. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Specifications > Page 5308 Antenna: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. The following four tests are used to diagnose the antenna with an ohmmeter: - Test 1 - Mast to ground test - Test 2 - Tip-of-mast to tip-of-conductor test - Test 3 - Body ground to battery ground test - Test 4 - Body ground to coaxial shield test. Antenna Tests The ohmmeter test lead connections for each test are shown in Antenna Tests. NOTE: This model has a two-piece antenna coaxial cable. Tests 2 and 4 must be conducted in two steps to isolate a coaxial cable problem; from the coaxial cable connection on the right end bracket of the instrument panel near the right cowl side inner panel to the antenna base, and then from the coaxial cable connection to the radio chassis connection. TEST 1 Test 1 determines if the antenna mast is insulated from the base. Proceed as follows: 1. Disconnect and isolate the antenna coaxial cable connector from the radio receiver chassis. 2. Connect one ohmmeter test lead to the tip of the antenna mast. Connect the other test lead to the antenna base. Check for continuity. 3. There should be no continuity. If continuity is found, replace the faulty or damaged antenna base and cable assembly. TEST 2 Test 2 checks the antenna for an open circuit as follows: 1. Disconnect the antenna coaxial cable connector from the radio receiver chassis. 2. Connect one ohmmeter test lead to the tip of the antenna mast. Connect the other test lead to the center pin of the antenna coaxial cable connector. 3. Continuity should exist (the ohmmeter should only register a fraction of an ohm). High or infinite resistance indicates damage to the base and cable assembly. Replace the faulty or damaged antenna base and cable, if required. TEST 3 Test 3 checks the condition of the vehicle body ground connection. This test should be performed with the battery positive cable removed from the battery. Disconnect both battery cables, the negative cable first. Reconnect the battery negative cable and perform the test as follows: 1. Connect one ohmmeter test lead to the vehicle fender. Connect the other test lead to the battery negative terminal post. 2. The resistance should be less than one ohm. 3. If the resistance is more than one ohm, check the braided ground strap(s) connected to the engine and the vehicle body for being loose, corroded, or damaged. Repair the ground strap connections, if required. TEST 4 Test 4 checks the condition of the ground between the antenna base and the vehicle body as follows: 1. Connect one ohmmeter test lead to the vehicle fender. Connect the other test lead to the outer crimp on the antenna coaxial cable connector. 2. The resistance should be less then one ohm. 3. If the resistance is more then one ohm, clean and/or tighten the antenna base to fender mounting hardware. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Specifications > Page 5309 Antenna: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

It is being provided with this Technical Service Bulletin to assist in properly installing communication equipment in DaimlerChrysler vehicles. This information should be given to any owner inquiring about installing radio-transmitting equipment. Installation Recommendations DaimlerChrysler Radio Communication Equipment Installation Recommendations Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Cellular Phone > Component Information > Technical Service Bulletins > Radio Communication Equipment - Recommendations > Page 5349 The following is excerpted from the owners manual of new DaimlerChrysler products: "INSTALLATION OF RADIO TRANSMITTING EQUIPMENT Special design considerations are incorporated into this vehicle's electronic system to provide immunity to radio frequency signals. Mobile two-way radio and telephone equipment must be installed properly by trained personnel. The following must be observed during installation. The positive power connection should be made directly to the battery and fused as close to the battery as possible. The negative power connection should be made to body sheet metal adjacent to the negative battery connection. This connection should not be fused. Antennas for two-way radios should be mounted on the roof or the rear area of the vehicle. Care should be used in mounting antennas with magnet bases. Magnets may affect the accuracy or operation of the compass on vehicles so equipped. The antenna cable should be as short as practical and routed away from the vehicle wiring when possible. Use only fully shielded coaxial cable. Carefully match the antenna and cable to the radio to ensure a low Standing Wave Ratio (SWR). Mobile radio equipment with output power greater than normal may require special precautions. All installations should be checked for possible interference between the communications equipment and the vehicle's electronic systems. A Technical Service Bulletin (TSB) is available for detailed assistance." The owner's first line of contact regarding vehicle problems is the dealer. The literature supplied with each vehicle lists the steps to be taken in the event the dealer is unable to resolve the problem. To assist in properly installing communications equipment in DaimlerChrysler vehicles, the following information is provided. Always use good construction practices (see The ARRL Handbook or other standard reference works). The information contained in this guide has been prepared for use by persons installing two-way radio equipment (transmitters and receivers) in vehicles. It has been prepared in accordance with current engineering principles and generally accepted practices, using the best information available at the time of publication. It is not possible to cover all of the possible installations of two-way radio equipment in this guide. Accordingly, DaimlerChrysler Corporation cannot be held responsible for incidental or consequent damages arising out of the use of the information contained herein. The responsibility for installations and modifications is the sole responsibility of the customer. The installation recommendations presented here are intended to supplement the radio manufacturer's instructions. Test the entire installation for anomalies, especially drivetrain and brake control before extensive driving. 1. CONTROLS Mount the transceiver to a solid surface. If you use screws through the floor pan, put body sealer over the underbody projections. (Stamped acorn nuts, filled with sealer are available at most body shops for this purpose.) This will keep moisture out of the carpet and insulation, and will forestall rust in this area. Watch out for wire harnesses routed under carpet and behind instrument panel. If you mount the radio under the instrument panel, be sure that there is no interference with proper operation of the foot controls. Mount the control head or front panel (especially the microphone cable) so that it is clear of the steering wheel and column controls and passenger airbag. If the unit is heavy, extra bracing may be needed for stability. Newer vehicles have more structure and energy absorbing materials in the knee blocker (the lower part of the Instrument Panel). For one-piece transceivers, if ignition switch control is desired, it is good practice to use a power relay to avoid overloading the ignition switch, and to maintain the advantages of direct battery feed. Try the installation out before you start drilling holes. 2. POWER WIRING To reduce the hazard of working on the vehicle, disconnect the battery NEGATIVE before beginning work. Note that some components may lose short-term memory (e.g.: radio presets) after a protracted time without battery power. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Cellular Phone > Component Information > Technical Service Bulletins > Radio Communication Equipment - Recommendations > Page 5350 For low or medium power transmitters (up to 55W FM or 110W SSB or CW), the power outlet or cigar lighter feed may be used. Use a 1/4" jumper terminal at the socket or splice (solder and heat shrink or tape). For higher power transmitters, including amplifiers, connect the power (battery +) lead at the battery or at the power distribution center or at the positive jump-start post, if the vehicle has one. An appropriate terminal should be used. If the terminal is exposed to the weather, solder and apply a commercial protectant (wheel bearing grease is an acceptable alternative.) to retard corrosion. This lead should be fused as close to the battery as practical to protect the wiring (and the vehicle)! If the power connection is underhood, use a weatherproof fuse holder. Motorola Communications Division supplies a weatherproof holder, part number 09-84277B01 for 5AG cartridge fuses that is part of their standard installation kit. Packard Electric Division of Delphi Automotive Systems makes an insulator, part number 12033769, terminal number 12020156 with cover 12033731 for standard SAE plastic fuses. Vinyl-insulated wire, typically supplied with transceivers is not entirely suitable for the higher underhood temperatures in modern vehicles. Route underhood wiring away from all hot areas. Body sheet metal, away from the exhaust, radiator, A/C liquid line and engine is usually the coolest location. DO NOT FUSE THE GROUND LEAD. If the ground-side fuse were to open, the entire supply current would be conducted by an alternate current return path, which could cause the feedline to overheat, with possible resulting damage. For low or medium power installations, connect the ground (battery -) to body sheet near the power feed point. If you use a screw through the floor, put body sealer over the underbody projection. (Stamped acorn nuts, filled with sealer are available at most body shops for this purpose.) For high power installations, connect the ground (battery -) lead at the battery connection to the body. This is usually a 6 or 8 AWG black wire from the battery negative terminal to a screw at the wheelhouse or radiator support. If a separate sheet metal ground is used, clean the paint off a one inch or so diameter area of body panel where the ground lead is to be connected (usually the case with commercial trunk mount radios). An awl is the best tool to use to pierce a starting hole for a #12 or 5mm, minimum plated ground screw. A ring terminal with lockwasher serrations of the proper size for the screw or a separate serrated (not a split or SAE) lockwasher should be used between the terminal and the screw head. As above, some grease or protectant should be used if the connection is in an unprotected area. If the power cable must pass through the dash panel, try to find an existing hole with a grommet that is unused. If none is available, pull the carpet back from under the dash panel in the passenger footwell in the cabin. Locate a place where there are no other components on either side, as high up as possible. An awl is the best tool to use to punch a small hole through to the engine compartment. If the position is good, enlarge the hole by driving the awl in up to the shank. If this is not large enough to easily pass the cable, enlarge it by using a larger tapered punch. This will leave an extruded hole with no sharp edges. Install the cable and seal the hole with silicone RTV or commercial body sealer on both sides. Seal any extra holes that you may have made. Dress the underhood wiring so that it is sate from all hazards, which include the following: exhaust manifold, steering shaft, throttle linkage, fans, etc. Tie wrap as required. 3. CABLING Route control cables under the floor mats, inside the corner where the floor pan meets the rocker panel for best protection. Remove the sill plates and tuck the cable under the floor mats or carpet and padding. For most left hand drive vehicles, use the right side for best separation to the main body harness (usually on the left side). Route the cable along the extreme outboard edge of the floor pan, under the side trim, if possible. 4. REMOTE TRANSCEIVER For trunk mount installations in passenger cars, you may need to remove the rear seat cushion and seat back to get the cable into the trunk. The seat cushion is usually clipped at the front, lower edge by its own frame: push down and back, then lift. Note the front and rear clipping points for ease of reinstallation. The seat back is usually clipped to the rear compartment inner panel: pull out at the bottom and slide up to remove. Again, note the clipping points for ease of reinstallation. There is usually a vapor/sound barrier behind the seat back, which must be pierced to pass the cable. Open the trunk and pick a spot where the cable is safe from chafing on any sharp sheet metal. Tie wrap or tape in place at this location. Repair the barrier sheet if necessary. Replace the seat back and cushion, taking care that the cable is not pinched by the seat cushion when there is someone sitting in the seat. On some vehicles, there may be a channel for wiring at this location. For remote control radios, a sheet of 1/2 in. plywood one or two inches larger than the radio, is a good method to mount the transceiver to the shelf. It provides a good mounting surface, some shock and vibration isolation, and it keeps moisture away from the radio. Mounting on the floor of the trunk is not recommended. To conserve trunk space, in some vehicles, the radio may be mounted to the rear compartment panel. Locate as far as possible from any vehicle electronic modules located in the rear of the vehicle. In any case, provide good air circulation; a 50 watt RF output FM transmitter will dissipate about 22 watts (@70% efficiency). Do not pile things on top of the unit. 5. TRANSMISSION LINE The transmission line (coaxial cable) should be treated in the same way as the control and power cables. Route flat along body sheet metal wherever possible to avoid sharp edges and pinches. If it is necessary to cross over wiring, cross at right angles. In some cases, additional shielding between the transmission line and the vehicle wiring may be helpful. It is important to maintain the maximum spacing from the vehicle harnesses, especially if the antenna is not a good match. Use the best cable available (98-99% braid coverage or braid/foil) especially at UHF and above. Mechanical pressure on the cable can cause degradation or even short circuits. Do not rely on the obsolete military "RG" designations as an indicator of quality. Cut off, do not coil excess transmission line (This forms a choke balun.) and terminate in the correct connector. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Cellular Phone > Component Information > Technical Service Bulletins > Radio Communication Equipment - Recommendations > Page 5351 The use of N, BNC or C connectors is recommended over "UHF" (PL-259/S0-239) connectors. A small amount of silicone dielectric grease (not the white heat sink compound) in the connector (after soldering) will minimize condensation problems. Cut the line as short as practical, to minimize losses. 6. ANTENNA LOCATION Antenna location is the most important consideration in any mobile installation. For VHF and UHF antennas the recommended place on almost all vehicles is in the center of the roof. The center of the deck lid is an acceptable alternate. Glass-mounted antennas should be mounted at the very top edge of the clear portion of the glass away from the heater grid. Vehicles with printed-on-glass antennas may be damaged by through-glass installations. For HF antennas, refer to the manufacturer's instructions and follow them closely, unless you are an accomplished antenna experimenter. HF antennas should be mounted to body or frame steel for a good counterpoise as well as structural strength. Aluminum bumpers are heavily anodized for corrosion protection, and the coating (aluminum oxide) is very hard as well as nonconductive. A small grinder with a coarse stone will break through the anodized coating for electrical connection. 7. ANTENNA INSTALLATION Permanently installed antennas are preferable over magnetic, glass or body-lip mounts for anything other than for low power or temporary installations. Most of these alternate antennas will reflect some power back at the feedpoint. Much of this will be radiated from the feedline inside the passenger compartment, and may be picked up by the vehicle wiring. For deck lid installations, the deck lid must be bonded to the body, across the hinges, with short, wide tinned braid straps. They must connect to clean sheet metal at both ends. For AM/SSB and even some FM installations, the hood must be bonded to the body. In some cases the doors may need to be bonded, as well. Glass-mount antennas will not work or will only work very poorly in vehicles with metallized glass (Electrically-heated windshields or some solar reflective glass). Non-metallic bodies (e.g., Viper) require a half-wavelength antenna or a ground plane with radius approximately equal to the length of a quarter-wave antenna. Copper is the best choice, but aluminum or even steel may be used. Install on the inside of the body panel with a good adhesive or tape and provide a good RF connection to the coax shield at the feedpoint. Screen, mesh or thin sheet stock may be used. Shape is not critical, but some directional characteristics may be noted if it is not round. Try to stay one-quarter wavelength away from edges, including sunroof openings. Consider the sunroof mechanism for interference to the base and to the feedline. For VHF and UHF, a good quality "NMO" (New Motorola) base or other mount with feedline (center conductor and shield) soldered to base is recommended. This will allow the maximum flexibility in antenna selection and is the best choice for electrical and mechanical considerations. Use the proper hole saw (3/4 in. for NMO) or have it done professionally if you are not comfortable with power tools. Hole plugs are available, for use at sale or trade-in, if you expect to remove the antenna base. To install the antenna base in the hole, remove the one or two-door trim pieces at the pillar where the cable is to be routed and ease the headliner away from the roof. Insert a piece of flat steel or plastic banding (1/2 in. to 3/4 in. wide) and guide to the desired corner. Pull the banding through, leaving 6 in., which can be taped, to the transmission line (easier without the connector, but possible even with a PL-259). Continue pulling until the antenna base is one inch or less from the hole, then seat the base and screw on the outside ring, 0-ring down. A little silicone grease helps maintain a good seal for the life of the vehicle. Tighten with an open-end wrench, and apply a small amount of silicone grease to the contact and insulator surface of the base. This will help exclude water, but must be renewed periodically. Tip: if you remove your antenna to go through the car wash, there are caps available to exclude water during the process. In most vehicles, RG-58-sized cable will fit between the pillar trim and body sheet metal. If necessary, the technique used on the roof can also be used to snake the cable down the inside the pillar. Install the connector very carefully. There are good instructions in The ARRL Handbook. Use a clean, hot, high-wattage iron and work quickly, to prevent damage to the cable dielectric. If you are a beginner or are not comfortable with this kind of detail work, ask for help. It is extremely important.

Use the best cable available (98-99% braid coverage or braid/foil) especially at UHF and above. Mechanical pressure on the cable can cause degradation or even short circuits. Do not rely on the obsolete military "RG" designations as an indicator of quality. Cut off, do not coil excess transmission line (This forms a choke balun.) and terminate in the correct connector. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Citizens Band Radio (CB) > Component Information > Technical Service Bulletins > Radio Communication Equipment - Recommendations > Page 5358 The use of N, BNC or C connectors is recommended over "UHF" (PL-259/S0-239) connectors. A small amount of silicone dielectric grease (not the white heat sink compound) in the connector (after soldering) will minimize condensation problems. Cut the line as short as practical, to minimize losses. 6. ANTENNA LOCATION Antenna location is the most important consideration in any mobile installation. For VHF and UHF antennas the recommended place on almost all vehicles is in the center of the roof. The center of the deck lid is an acceptable alternate. Glass-mounted antennas should be mounted at the very top edge of the clear portion of the glass away from the heater grid. Vehicles with printed-on-glass antennas may be damaged by through-glass installations. For HF antennas, refer to the manufacturer's instructions and follow them closely, unless you are an accomplished antenna experimenter. HF antennas should be mounted to body or frame steel for a good counterpoise as well as structural strength. Aluminum bumpers are heavily anodized for corrosion protection, and the coating (aluminum oxide) is very hard as well as nonconductive. A small grinder with a coarse stone will break through the anodized coating for electrical connection. 7. ANTENNA INSTALLATION Permanently installed antennas are preferable over magnetic, glass or body-lip mounts for anything other than for low power or temporary installations. Most of these alternate antennas will reflect some power back at the feedpoint. Much of this will be radiated from the feedline inside the passenger compartment, and may be picked up by the vehicle wiring. For deck lid installations, the deck lid must be bonded to the body, across the hinges, with short, wide tinned braid straps. They must connect to clean sheet metal at both ends. For AM/SSB and even some FM installations, the hood must be bonded to the body. In some cases the doors may need to be bonded, as well. Glass-mount antennas will not work or will only work very poorly in vehicles with metallized glass (Electrically-heated windshields or some solar reflective glass). Non-metallic bodies (e.g., Viper) require a half-wavelength antenna or a ground plane with radius approximately equal to the length of a quarter-wave antenna. Copper is the best choice, but aluminum or even steel may be used. Install on the inside of the body panel with a good adhesive or tape and provide a good RF connection to the coax shield at the feedpoint. Screen, mesh or thin sheet stock may be used. Shape is not critical, but some directional characteristics may be noted if it is not round. Try to stay one-quarter wavelength away from edges, including sunroof openings. Consider the sunroof mechanism for interference to the base and to the feedline. For VHF and UHF, a good quality "NMO" (New Motorola) base or other mount with feedline (center conductor and shield) soldered to base is recommended. This will allow the maximum flexibility in antenna selection and is the best choice for electrical and mechanical considerations. Use the proper hole saw (3/4 in. for NMO) or have it done professionally if you are not comfortable with power tools. Hole plugs are available, for use at sale or trade-in, if you expect to remove the antenna base. To install the antenna base in the hole, remove the one or two-door trim pieces at the pillar where the cable is to be routed and ease the headliner away from the roof. Insert a piece of flat steel or plastic banding (1/2 in. to 3/4 in. wide) and guide to the desired corner. Pull the banding through, leaving 6 in., which can be taped, to the transmission line (easier without the connector, but possible even with a PL-259). Continue pulling until the antenna base is one inch or less from the hole, then seat the base and screw on the outside ring, 0-ring down. A little silicone grease helps maintain a good seal for the life of the vehicle. Tighten with an open-end wrench, and apply a small amount of silicone grease to the contact and insulator surface of the base. This will help exclude water, but must be renewed periodically. Tip: if you remove your antenna to go through the car wash, there are caps available to exclude water during the process. In most vehicles, RG-58-sized cable will fit between the pillar trim and body sheet metal. If necessary, the technique used on the roof can also be used to snake the cable down the inside the pillar. Install the connector very carefully. There are good instructions in The ARRL Handbook. Use a clean, hot, high-wattage iron and work quickly, to prevent damage to the cable dielectric. If you are a beginner or are not comfortable with this kind of detail work, ask for help. It is extremely important.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Radio/Stereo > Component Information > Diagrams > Diagram Information and Instructions > Page 5377 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Radio/Stereo > Component Information > Diagrams > Diagram Information and Instructions > Page 5378 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Radio/Stereo > Component Information > Diagrams > Diagram Information and Instructions > Page 5379 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Radio/Stereo > Component Information > Diagrams > Diagram Information and Instructions > Page 5380 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Radio/Stereo > Component Information > Diagrams > Diagram Information and Instructions > Page 5381 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Radio/Stereo > Component Information > Diagrams > Diagram Information and Instructions > Page 5382 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number for the subsequent diagram will match a listed group shown. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Radio/Stereo > Component Information > Diagrams > Diagram Information and Instructions > Page 5383 Connector and Terminal Replacement 1.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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.

Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Radio/Stereo > Component Information > Diagrams > Diagram Information and Instructions > Page 5394 Radio/Stereo: Electrical Diagrams Base 8w-47-2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Radio/Stereo > Component Information > Diagrams > Diagram Information and Instructions > Page 5395 8w-47-3 NOTE: To view sheets referred to in these diagrams, see Complete Body and Chassis Diagrams See: Diagrams/Electrical Diagrams/Diagrams By Group Number.

The standard equipment audio system includes an AM/FM (RAS sales code) stereo receiver, and speakers in four locations. Several combinations of radio receivers and speaker systems are offered as optional equipment on this model. The audio system uses an ignition switched source of battery current so that the system will only operate when the ignition switch is in the On or Accessory positions. The audio system includes the following components: Antenna - Power amplifier (with premium speaker system only) - Radio noise suppression components - Radio receiver - Speakers OPERATION See the owner's manual in the vehicle glove box for more information on the features, use and operation of each of the available audio systems. RADIO RECEIVER DESCRIPTION Available factory-installed radio receivers for this model include an AM/FM (RAS sales code), an AM/FM/cassette (RAS sales code), an AM/FM/cassette/5-band graphic equalizer with CD changer control feature (RBN sales code), an AM/FM/CD/3-band graphic equalizer (RBR sales code), or an AM/FM/CD/ cassette/3-band graphic equalizer (RAZ sales code). All factory-installed receivers are stereo Electronically Tuned Radios (ETR) and include an electronic digital clock function. These radio receivers can only be serviced by an authorized radio repair station. See the latest Warranty Policies and Procedures for a current listing of authorized radio repair stations. Ignition-off Draw Fuse All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is removed when the vehicle is shipped from the factory. This fuse feeds various accessories that require battery current when the ignition switch is in the Off position, including the clock. The IOD fuse is removed to prevent battery discharge during vehicle storage. When removing or installing the IOD fuse, it is important that the ignition switch be in the Off position. Failure to place the ignition switch in the Off position can cause the radio display to become scrambled when the IOD fuse is removed and replaced. Removing and replacing the IOD fuse again, with the ignition switch in the Off position, will correct the scrambled display condition. The IOD fuse should be checked if the radio or clock displays are inoperative. The IOD fuse is located in the junction block. Refer to the fuse layout label on the back of the instrument panel fuse access panel for IOD fuse identification and location. OPERATION The radio receiver operates on fused battery cur- rent that is available only when the ignition switch is in the On or Accessory positions. The electronic digital clock function of the radio operates on fused battery current supplied through the IOD fuse, regardless of the ignition switch position. For more information on the features, setting procedures, and control functions for each of the available factory-installed radio receivers, see the owner's manual in the vehicle glove box. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Radio/Stereo > Component Information > Diagrams > Page 5402 Radio/Stereo: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING.

Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5451 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5452 3.

Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions Trailer Connector: Diagram Information and Instructions Introduction General Information (Part 1 Of 2) Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5457 General Information (Part 2 Of 2) Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content.

Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5461 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING.

Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5463 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5473 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5474 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Locations Central Timer Module, Left Center Support, Wire Harness Connectors, Screw Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Locations > Page 5480 Body Control Module: Service Precautions Before disconnecting any control module, make sure the ignition is "OFF". Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System Body Control Module: Description and Operation Airbag System Airbag System Description AIRBAG SYSTEM The Airbag Control Module (ACM) is secured to a bracket on the floor panel below the drivers seat. The ACM contains a microprocessor, the impact sensor, and energy storage capacitor. The microprocessor contains the airbag system logic. The ACM system logic includes On-Board Diagnostics (OBD) capability, and communicates with the instrument cluster circuitry on the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor in the ACM monitors the impact sensor signal and the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster on the CCD data bus to turn on the airbag indicator lamp. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbag system components. Only one impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags, for one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. The airbag warning lamp is the only point at which the customer can observe "symptoms" of a system malfunction, Whenever the ignition key is turned to the RUN or START position, the MIC performs a lamp check by turning the AIRBAG warning lamp ON for 6-8 seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the system or the MIC lamp circuit may be internally shorted to ground. If the lamp comes ON and stays ON for a period longer than 6-8 seconds then goes OFF, there is usually an intermittent problem in the system. The MIC monitors the airbag warning lamp and seat belt warning lamp during the bulb check for a defective bulb or lamp driver circuit. The MIC tests the airbag lamp during the cluster bulb check and substitutes the seat belt lamp if the airbag lamp is defective. If the airbag lamp is defective the MIC will turn the seat belt light ON and OFF approximately 30 times to warn the driver that the airbag lamp is defective. The lamp status is sent to the ACM continuously via a CCD bus message. The seat belt lamp acts as a backup in the event that the AIRBAG lamp is defective. This information is sent to the ACM continuously via a CCD bus message. Perform the WARNING LAMP BULB OR DRIVER procedure in this book to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated with no active DTC's The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. Service and general information labels about the airbag system can be found on the driver's sun visor, the glove box door, and in the engine compartment. WARNING: FAILURE TO HAVE THE AIRBAG SYSTEM PROPERLY SERVICED BY AN AUTHORIZED DEALER MAY LEAD TO POSSIBLE INJURY IN THE EVENT OF AN ACCIDENT. Driver Airbag Module (DAB) DRIVER AIRBAG MODULE (DAB) Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 5483 The airbag protection trim cover is the most visible part of the driver side airbag system. The module is mounted directly to the steering wheel. Located under the trim cover are the horn switch, the airbag cushion, and the airbag cushion supporting components. The airbag module includes a housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator seals the hole in the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. The protective trim cover is fitted to the front of the airbag module and forms a decorative cover in the center of the steering wheel. Upon airbag deployment, this cover will split at a predetermined breakout line. THE AIRBAG MODULE INFLATOR ASSEMBLY CONTAINS SODIUM AZIDE AND POTASSIUM NITRATE.

Clockspring CLOCKSPRING The clockspring is mounted on the steering column behind the steering wheel. This assembly consists of a plastic housing which contains a flat, ribbon-like, electrically conductive tape that winds and unwinds with the steering wheel rotation. The clockspring is used to maintain a continuous electrical circuit between the instrument panel wire harness and the driver side airbag module, the horn switch, and the vehicle speed control switches on vehicles that are so equipped. The clockspring must be properly centered when it is installed on the steering column following any service removal, or it will be damaged. The clockspring cannot be repaired it must be replaced. Passenger Airbag Module (PAB) PASSENGER AIRBAG MODULE (PAB) The airbag door in the instrument panel top cover above the glove box is the most visible part of the passenger side airbag system. Located under the airbag door is the airbag cushion and it's supporting components. The airbag module includes a housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator includes a small canister of highly compressed argon gas. The inflator seals the hold in the airbag cushion so it can discharge the compressed gas it contains directly into the cushion when supplied with the proper electrical signal. The airbag door has a living hinge at the top, which is secured to the instrument panel top cover. The door also has predetermined breakout lines concealed beneath its decorative cover. Upon airbag deployment the airbag door will split at the breakout lines and the door will pivot out of the way. The airbag module is secured at the bottom to the steel structural base of the instrument panel above the glove box opening. The airbag door is serviced as a unit with the passenger side airbag module, and includes the two passenger heating and air conditioning panel outlet housings. Following an airbag deployment, the airbag module and the instrument panel assembly must be replaced. Passenger Airbag On/Off Switch PASSENGER AIRBAG ON/OFF SWITCH The passenger side airbag ON/OFF switch is located on the instrument panel. To de-activate the passenger side airbag, turn the key actuator switch from the horizontal position to a slanted position (pointing to the "OFF" light indicator), approximately 45 degrees clockwise from the "ON" position. Rotating the key actuator switch 45 degrees clockwise, remove the key completely from the switch and verify that the switch actuator hole stays in the new position (45 degrees clockwise from horizontal). The switch is spring loaded to the "ON" position. It will return to the "ON" position unless you remove the key. When the IGNITION in ON, this procedure will illuminate the "OFF" light indicator on the passenger airbag ON/OFF switch. To re-enable the passenger side airbag, reverse the procedure above so that the key switch actuator is returned to a horizontal position. NOTE: DO NOT TURN IGNITION ON WITH KEY IN SWITCH. DO NOT TURN SWITCH WITH IGNITION ON. DO NOT LEAVE KEY IN SWITCH. THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG ON/OFF SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED.

The CCD data bus network allows the sharing of information between modules and diagnostic capability using the DRB III. The CTM equipped vehicles can be identified by the sound of a Key-In Ignition CHIME. The Base AB RAM VAN body system is composed of individual modules. Because the stand-alone modules do not communicate on the CCD Bus, they cannot be diagnosed using the DRB. For concerns about the BASE AB VAN, refer to the appropriate service procedures. The Base version can be identified by the sound of the Key-In Ignition BUZZER. The CTM provides the following features: CCD Bus Communication - Chime - Courtesy Lamp Controls/Illuminated Entry - Enhanced Accident Response - Intermittent Wiper Delay - Power Door Locks W/RKE - Remote Keyless Entry (RKE) - Speed Sensitive Intermittent Wipers - Vehicle Theft Security System (VTSS) The module is located on the left center instrument panel support. It contains a white 18-way and a green 14-way connector.

The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for gauge problems and tell tale warnings. The CTM chime functions will have priority over the MIC chime requests. There are two chime rates, Low; 50 chimes per minute for reminders and High; 180 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the driver door is open or the headlights are left ON. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for the key-in, and headlamp warning, as long as the drivers door is open. The seat belt warning chime is activated for 4 to 6 seconds , and all other chime conditions will activate the chime once at the same time the warning light ON the cluster is illuminated. The chime will sound for the following conditions: High rate Key in Warning ignition off, key in ignition, driver's door open - Ignition off, headlamps ON, driver's door open Low rate Seat belt warning - 6 seconds after key on (6 to 8 chimes) or until seatbelt is buckled - Airbag lamp illuminated (3 times after prove-out) - ABS lamp illuminated (2 chimes after prove-out if equipped) - Check engine lamp illuminated (2 chimes after prove-out) - Check gauges lamp illuminated (2 chimes) - Engine Temp High - when gauge enters red zone (2 chimes) - Low fuel - when fuel level reaches 1/8 tank (2 chimes) - Low washer fluid (2 chimes) - Transmission Temperature High (2 chimes) If the ignition switch is turned to the RUN/START position and the driver's door is closed, then opened, the warning chime is defeated. This allows the doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the OFF position, then normal function will be restored. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 5488 Body Control Module: Description and Operation Airbag System Description AIRBAG SYSTEM The Airbag Control Module (ACM) is secured to a bracket on the floor panel below the drivers seat. The ACM contains a microprocessor, the impact sensor, and energy storage capacitor. The microprocessor contains the airbag system logic. The ACM system logic includes On-Board Diagnostics (OBD) capability, and communicates with the instrument cluster circuitry on the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor in the ACM monitors the impact sensor signal and the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster on the CCD data bus to turn on the airbag indicator lamp. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbag system components. Only one impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags, for one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. The airbag warning lamp is the only point at which the customer can observe "symptoms" of a system malfunction, Whenever the ignition key is turned to the RUN or START position, the MIC performs a lamp check by turning the AIRBAG warning lamp ON for 6-8 seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the system or the MIC lamp circuit may be internally shorted to ground. If the lamp comes ON and stays ON for a period longer than 6-8 seconds then goes OFF, there is usually an intermittent problem in the system. The MIC monitors the airbag warning lamp and seat belt warning lamp during the bulb check for a defective bulb or lamp driver circuit. The MIC tests the airbag lamp during the cluster bulb check and substitutes the seat belt lamp if the airbag lamp is defective. If the airbag lamp is defective the MIC will turn the seat belt light ON and OFF approximately 30 times to warn the driver that the airbag lamp is defective. The lamp status is sent to the ACM continuously via a CCD bus message. The seat belt lamp acts as a backup in the event that the AIRBAG lamp is defective. This information is sent to the ACM continuously via a CCD bus message. Perform the WARNING LAMP BULB OR DRIVER procedure in this book to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated with no active DTC's The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. Service and general information labels about the airbag system can be found on the driver's sun visor, the glove box door, and in the engine compartment. WARNING: FAILURE TO HAVE THE AIRBAG SYSTEM PROPERLY SERVICED BY AN AUTHORIZED DEALER MAY LEAD TO POSSIBLE INJURY IN THE EVENT OF AN ACCIDENT. Driver Airbag Module (DAB) DRIVER AIRBAG MODULE (DAB) The airbag protection trim cover is the most visible part of the driver side airbag system. The module is mounted directly to the steering wheel. Located under the trim cover are the horn switch, the airbag cushion, and the airbag cushion supporting components. The airbag module includes a Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 5489 housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator seals the hole in the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. The protective trim cover is fitted to the front of the airbag module and forms a decorative cover in the center of the steering wheel. Upon airbag deployment, this cover will split at a predetermined breakout line. THE AIRBAG MODULE INFLATOR ASSEMBLY CONTAINS SODIUM AZIDE AND POTASSIUM NITRATE. THESE MATERIALS ARE POISONOUS AND EXTREMELY FLAMMABLE. CONTACT WITH ACID, WATER, OR HEAVY METALS MAY PRODUCE HARMFUL AND IRRITATING GASES (SODIUM HYDROXIDE IS FORMED IN THE PRESENCE OF MOISTURE) OR COMBUSTIBLE COMPOUNDS, IN ADDITION, THE PASSENGER AIRBAG MODULE CONTAINS ARGON GAS PRESSURIZED TO OVER 2500 PSI. DO NOT ATTEMPT TO DISMANTLE AN AIRBAG MODULE OR TAMPER WITH ITS INFLATOR. DO NOT PUNCTURE, INCINERATE, OR BRING INTO CONTACT WITH ELECTRICITY DO NOT STORE AT TEMPERATURE EXCEEDING 93°C (200°F). Clockspring CLOCKSPRING The clockspring is mounted on the steering column behind the steering wheel. This assembly consists of a plastic housing which contains a flat, ribbon-like, electrically conductive tape that winds and unwinds with the steering wheel rotation. The clockspring is used to maintain a continuous electrical circuit between the instrument panel wire harness and the driver side airbag module, the horn switch, and the vehicle speed control switches on vehicles that are so equipped. The clockspring must be properly centered when it is installed on the steering column following any service removal, or it will be damaged. The clockspring cannot be repaired it must be replaced. Passenger Airbag Module (PAB) PASSENGER AIRBAG MODULE (PAB) The airbag door in the instrument panel top cover above the glove box is the most visible part of the passenger side airbag system. Located under the airbag door is the airbag cushion and it's supporting components. The airbag module includes a housing to which the cushion and inflator are attached and sealed. The airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The inflator assembly is mounted to the back of the airbag module. The inflator includes a small canister of highly compressed argon gas. The inflator seals the hold in the airbag cushion so it can discharge the compressed gas it contains directly into the cushion when supplied with the proper electrical signal. The airbag door has a living hinge at the top, which is secured to the instrument panel top cover. The door also has predetermined breakout lines concealed beneath its decorative cover. Upon airbag deployment the airbag door will split at the breakout lines and the door will pivot out of the way. The airbag module is secured at the bottom to the steel structural base of the instrument panel above the glove box opening. The airbag door is serviced as a unit with the passenger side airbag module, and includes the two passenger heating and air conditioning panel outlet housings. Following an airbag deployment, the airbag module and the instrument panel assembly must be replaced. Passenger Airbag On/Off Switch PASSENGER AIRBAG ON/OFF SWITCH The passenger side airbag ON/OFF switch is located on the instrument panel. To de-activate the passenger side airbag, turn the key actuator switch from the horizontal position to a slanted position (pointing to the "OFF" light indicator), approximately 45 degrees clockwise from the "ON" position. Rotating the key actuator switch 45 degrees clockwise, remove the key completely from the switch and verify that the switch actuator hole stays in the new position (45 degrees clockwise from horizontal). The switch is spring loaded to the "ON" position. It will return to the "ON" position unless you remove the key. When the IGNITION in ON, this procedure will illuminate the "OFF" light indicator on the passenger airbag ON/OFF switch. To re-enable the passenger side airbag, reverse the procedure above so that the key switch actuator is returned to a horizontal position. NOTE: DO NOT TURN IGNITION ON WITH KEY IN SWITCH. DO NOT TURN SWITCH WITH IGNITION ON. DO NOT LEAVE KEY IN SWITCH. THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG ON/OFF SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE ON/OFF KEY CYLINDER. The ON/OFF switch cannot be adjusted or repaired and, if faulty or damaged, the ON/OFF switch must be replaced.

Interior Lighting INTERIOR LIGHTING The illuminated Entry system consist of a maximum of three dome lamps which are located in the front, middle and rear of the head liner. While the vehicle is off the illuminated entry feature can be activated in the following ways. Whenever a door is opened - When the vehicle is unlocked with a key - When the CTM receives a valid unlock signal from the RKE transmitter The illuminated entry will remain ON for 30 seconds after the last door is closed, turn OFF immediately after ignition is turned ON, or turn OFF when the CTM receives a LOCK message from the RKE transmitter. 15 Minute Illumination Timeout If the ignition is OFF and either front door is open, interior illumination will terminate after 15 minutes. If either front door is open and the ignition is turned in the RUN or ACCESSORY position, interior illumination will continue until the ignition is turned OFF. Once the ignition is OFF, if either front door remains open, the 15 minute interior illumination timeout will begin. Note: This timeout feature does not apply to either auxiliary door or the dome lamp switch which are hardwired to the courtesy lamps. The auxiliary door switches are also wired to the CTM to operate illuminated entry. Central Timer Module CENTRAL TIMER MODULE (CTM) The AB RAM VAN has two different body electrical systems, High Line and Base. The High Line utilizes a Central Timer Module (CTM) to provide the body features listed below. The CTM was designed to reduce cost, wiring complexity, and improve the system reliable. The CTM interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of information between modules and diagnostic capability using the DRB III. The CTM equipped vehicles can be identified by the sound of a Key-In Ignition CHIME. The Base AB RAM VAN body system is composed of individual modules. Because the stand-alone modules do not communicate on the CCD Bus, they cannot be diagnosed using the DRB. For concerns about the BASE AB VAN, refer to the appropriate service procedures. The Base version can be identified by the sound of the Key-In Ignition BUZZER. The CTM provides the following features: CCD Bus Communication - Chime - Courtesy Lamp Controls/Illuminated Entry - Enhanced Accident Response - Intermittent Wiper Delay - Power Door Locks W/RKE - Remote Keyless Entry (RKE) - Speed Sensitive Intermittent Wipers - Vehicle Theft Security System (VTSS) The module is located on the left center instrument panel support.

The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for the key-in, and headlamp warning, as long as the drivers door is open. The seat belt warning chime is activated for 4 to 6 seconds , and all other chime conditions will activate the chime once at the same time the warning light ON the cluster is illuminated. The chime will sound for the following conditions: High rate Key in Warning ignition off, key in ignition, driver's door open - Ignition off, headlamps ON, driver's door open Low rate Seat belt warning - 6 seconds after key on (6 to 8 chimes) or until seatbelt is buckled - Airbag lamp illuminated (3 times after prove-out) - ABS lamp illuminated (2 chimes after prove-out if equipped) - Check engine lamp illuminated (2 chimes after prove-out) - Check gauges lamp illuminated (2 chimes) - Engine Temp High - when gauge enters red zone (2 chimes) - Low fuel - when fuel level reaches 1/8 tank (2 chimes) - Low washer fluid (2 chimes) - Transmission Temperature High (2 chimes) If the ignition switch is turned to the RUN/START position and the driver's door is closed, then opened, the warning chime is defeated. This allows the doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the OFF position, then normal function will be restored. Description and Functional Operation DESCRIPTION AND FUNCTIONAL OPERATION The body system on the 1999 AB HIGH LINE consists of three modules that communicate over the CCD bus (Chrysler Collision Detection multiplex system). There are two additional modules, the Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are performed through the Serial Communication Interface of SCI, the same as previous years. All of the information about the functioning of all the system is organized, controlled, and communicated by (CCD Bus). Through the CCD bus, information about the operation of vehicle components and circuits is relayed quickly to the appropriate module(s). All modules receive all the information transmitted on the bus even though a module may not require all the information to perform it's function. It will only respond to messages "addressed" to it through a binary coding process. This method of data transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. DRB III Error Messages and Blank Screen DRB III ERROR MESSAGES AND BLANK SCREEN Under normal operation, the DRB will display one of only two error messages: User-Requested WARM Boot or - User-Requested COLD Boot If the DRB should display any other error message, record the entire display and call the MDS Hotline, or call for information and assistance at 1-800-825-8737. This is a sample of such an error message display: ver: 2.14 date: 26 Jul93 file: key_itf.cc date: Jul 26 1993 line: 548 err: Ox1 User-Requested COLD Boot Press MORE to switch between this display and the application screen. Press F4 when done noting information. DRB III Does Not Power Up (Blank Screen) If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (Data Link Connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, and inoperative DRB may be the result of a faulty cable or vehicle wiring. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 5492 DRB III Scan Tool Display Is Not Visible Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition. Enhanced Accident Response (Highline CTM Only) ENHANCED ACCIDENT RESPONSE (Highline Only) If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The interior lights will be turned ON 10 seconds after getting zero speed message on the CCD bus. In addition to unlocking the doors, the lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "OFF" position, normal operation will resume. Diagnostics DIAGNOSTICS Gauges The instrument cluster will not store any DTC's. Because the engine controller PCM gathers all the gauge information and sends it to the cluster via the bus, it is the controller's responsibility to monitor these inputs and store DTC's for them. For this reason the first item to be checked regarding a gauge problem (except oil pressure) should be the engine controller for any DTC's relating to the gauge in question. There are DTC's associated with all the gauges except for the oil pressure gauge. When diagnosing gauges, the input that is used for gauge message (fuel level sender for example) must be valid. Because of OBD II requirements, most of the information used for monitoring the OBD II system happens to be the same information used by the controller to formulate the gauge bus messages. OBD II requirement state that the fuel level sender must be checked for rationality. This includes determining if the sending unit voltage is too high or too low or if the voltage hasn't changed over time. If the PCM has determined that the sender information isn't valid, it will send a diagnostic trouble code. The presence or absence of the fuel level sending code in the PCM is an important factor to determine whether a fuel gauge problem is in the sending unit or the cluster. The same situation is used in all cluster diagnostics related to gauge operation with the exception of the oil pressure gauge. OBD II requirements do not include oil pressure monitoring. Therefore, oil pressure diagnostic would dictate that a mechanical oil pressure gauge be attached to the engine for absolute verification of oil pressure readings. Hard Wired Lamps The cluster contains several hard wired lamps described earlier. The lamps are set up in two configurations. Either the cluster supplies power and ground is supplied by the circuit being monitored or the lamp is supplied ground by the cluster and power comes from a module or other device. Refer to the schematic for the specific details on the lamp in question. Verification of the bulb filament may be required in cases of an inoperative lamp. This will require removal of the cluster and bulb in question. NOTE: THE BRAKE, TRANS TEMP, CHECK GAUGES, SEAT BELTS AND AIRBAG WARNING LAMPS ARE LED'S, ALL OTHER ARE BULBS. IF ANY LED'S ARE DEFECTIVE,THE INSTRUMENT CLUSTER MUST BE REPLACED. CCD Controlled Lamps The cluster contains several CCD controlled lamps as described earlier. These lamps are part of the diagnostic self-test. When entering the self-test mode, operation of these lamps can be observed. If the bulb fails to operate during the self-test and the bulb filament is good, the cluster assembly will need to be replaced. NOTE: A FLASHING SEAT BELT LAMP INDICATES THAT THE AIRBAG WARNING LAMP IS NOT OPERATING PROPERLY. Mechanical Instrument Cluster Description MECHANICAL INSTRUMENT CLUSTER (MIC) Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 5493 The Ram Van uses a standard MIC in all of it's U.S. vehicles. The cluster has 5 gauges and 15 indicator lamps. The gauges are positioned with information received over the CCD bus. Some of the indicator lamps are hardwired and the cluster using CCD bus information controls some. The MIC is hardwired to the CTM to provide the warning lamp announcement chimes. There is a self-test available for the cluster that will actuate all the gauges to their calibration points. The self test will not run if the cluster sees engine RPM or vehicle speed. The test will light all CCD controlled lamps for verification of lamp operation. It also forces the odometer Liquid Crystal Display (LCD) to perform a segment check. The self test routine can be entered by pressing and holding the trip reset button while rotating the ignition key from the OFF position to the ON position. When the word "check" appears, release the button and the test will continue. The cluster will provide bus bias termination and the engine controller provides a second termination. If the cluster is disconnected, the bus will not be biased. The cluster will be serviced as an assembly. There will be limited parts available, bulbs and sockets, the front lens, the trip odometer system cover and the rear cover assembly. No internal parts of the cluster will be serviceable. Normal Operation At key ON, the cluster will light the low fuel, seat belt, check gauges, and airbag. As the key is turned farther towards the start position, the check engine, ABS (if equipped) and brake warning lamp will illuminate. The liquid crystal display (LCD) will indicate the mileage stored inside the cluster. If there is a bus failure and the cluster cannot receive distance pulses from the engine controller, the cluster will display the last mileage stored until the ignition is turned OFF. If the cluster is receiving bus messages but is unable to display odometer information because of an internal failure, the odometer display will be blank. Dimming is handled by the potentiometer that controls instrumentation illumination. Lamps (Hardwired) The following lamps are hardwired in the cluster and are not part of the self-test. High Beam - Left Turn Signal - Right Turn Signal - Brake (comes ON during self-test) - Low Wash (comes during self-test) - Seat Belt (comes ON during self-test) Lamps (CCD) The cluster via CCD messages controls the following lamps. They are actuated during the self-test procedure. ABS lamps - Airbag - Check Engine - Check Gauges - Cruise Control Lamp - Security - Trans Temp - O/D OFF - Low Fuel Warning - Internally controlled by the cluster; not CCD NOTE: THE TURN SIGNALS, HIGH BEAM INDICATOR, SEAT BELT WARNING LAMP,LOW WASHER WARNING LAMP, AND BRAKE WARNING LAMP ARE HARDWIRED TO THE CLUSTER. Power Door Lock System POWER DOOR LOCKS The CTM controls the door lock actuation assemblies to handle locking and unlocking with the interior door lock switches or the RKE transmitter (key fob). There is also a door lock inhibit feature that prevents the power locking of the doors if the key is in the ignition or the headlamps are ON and the left front door is open. However, the doors can still be locked using the RKE transmitter which allows the engine to run for warm up purposes. Automatic (Rolling) Door Locks When the doors are closed and the vehicle speed exceeds 15 MPH due to engine power (not just rolling) and all doors are closed, the CTM will lock the doors. The vehicle is shipped with the automatic door lock feature disabled, but may be enabled using the DRB. Door Lock Delay If the CTM receives a signal to lock the doors and one or both of the auxiliary doors (side or rear) are open, the front doors will still lock. Five seconds after both of the auxiliary door are closed, the CTM will recycle the lock function. Remote Keyless Entry The CTM is compatible with a two button TRW RKE transmitter (keyfob). Two pre-programmed transmitters will be supplied with each vehicle. The CTM is capable of retaining up to four transmitters which can be programmed using the DRB. When a signal encoded with the correct vehicle access code is received and contains a valid message, the CTM will activate the corresponding relay to lock or unlock the doors. When an unlock Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 5494 message is sent, all the doors will unlock, the VTSS will disarm and the illuminated entry will be activated. When a lock message is sent and all the doors are closed, all the doors will lock, the VTSS arming sequence will begin and the illuminated entry will turn OFF. Horn chirp When the doors are locked using the transmitter, a horn chirp will sound to let the customer know the doors were locked. The vehicle will be shipped with this function disabled but may be enabled using the DRB. The duration of the horn chirp can also be changed using the DRB. Trouble Codes AIRBAG DIAGNOSTIC TROUBLE CODES Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists, diagnostic priority should be given to the active codes. Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the trouble codes. It is not necessary to perform all of the tests in this book to diagnose an individual code. Always begin by reading the diagnostic trouble codes using the DRB III. This will direct you to the specific test(s) that must be performed Active diagnostic trouble codes for the airbag system are not permanent and will change the moment the reason for the code is corrected. In certain test procedures within this , diagnostic trouble codes are used as a diagnostic tool. Active Codes The code becomes active as soon as the malfunction is detected or key-OFF, whichever occurs first. An active trouble code indicates an on-going malfunction. This means that the defect is currently there every time the airbag control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected. With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present. The seat belt lamp replaces the airbag lamp if the airbag lamp is defective. The seat belt lamp pulses ON and OFF 30 times if the airbag warning lamp is defective. Stored Codes Airbag codes are automatically stored in the ACM's memory as soon as the malfunction is detected. The exception is the "Loss of Ignition Run Only" code which is an active code only. A "stored" code indicates there was an active code present sometime. However, the code currently may not be present as an active code, although another active code could be. When a trouble code occurs, the airbag warning lamp illuminates for 12 seconds minimum (even if the problem existed for less than 12 seconds). The code is stored, along with the time in minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. The minimum time shown for any code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two minutes 13 seconds, for example, would be three minutes. If malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored code. If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the problem. In this case, the stored code can indicate an area to inspect. If no obvious problems are found, erase stored codes, and with the ignition "ON" wiggle the wire harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes periodically as you work through the system. This procedure may uncover a malfunction that is difficult to locate. Airbag Trouble Codes The Airbag Control Module may report any of the following diagnostic trouble codes. For the following codes, replace the Airbag Control Module (ACM) even if set intermittently: ACM ACCELEROMETER - ACM OUTPUT DRIVER CIRCUIT OPEN - ACM INTERNAL DIAGNOSTIC CODE # 1 - ACM INTERNAL DIAGNOSTIC CODE # 2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 5495 - ACM STORED ENERGY - ACM OUTPUT DRIVER For these codes, refer to the appropriate diagnostic procedure: Cluster Message Mismatch Driver Squib Circuit Open Driver Squib Circuit Shorted Driver Squib Circuit Shorted to Battery Driver Squib Circuit Shorted to Ground Loss of Ignition Run Only Loss of Ignition Run/Start NO Cluster CCD Message No CCD Communication Passenger Squib Circuit Open Passenger Squib Circuit Shorted Passenger Squib Circuit Shorted to Battery Passenger Squib Circuit Shorted to Ground Warning Lamp Open/Shorted Vehicle Communication VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the higher priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus -" (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a voltage divider network located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems use more than one. Some modules are capable of biasing and terminating the bus by themselves. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. Without termination, voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. In the 1999 Ram Van, the instrument cluster supplies bus bias and termination and the PCM supplies an additional point of termination. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLES ON-BOARD DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING.IF THERE IS A PROBLEM, REFER TO THE VEHICLE COMMUNICATION. Vehicle Theft Security System (VTSS) VEHICLE THEFT SECURITY SYSTEM (VTSS) The VTSS will monitor the states of the ignition, door lock signal, and all other doors to alert against unauthorized entry into the vehicle. The VTSS will be enabled at the assembly plant. To prevent arming of the VTSS during assembly and the shipping process, the vehicle must be started 20 times before the VTSS will operate properly. Arming the VTSS To arm the system, the ignition must be OFF and all doors must be closed and locked using either the power door lock switches or the RKE transmitter. Using a key or pressing the mechanical lock soldier will not initiate arming the VTSS. The delay lock feature will delay the arming process until all doors are closed. Once the VTSS begins to arm, the CTM will activate the security lamp output at a 1 Hz rate. During this process the arming process will terminate if the ignition is turned ON, if a door is opened, if the doors are unlocked using the door lock switch or the RKE transmitter, or if the front doors are unlocked using the key. After fifteen seconds of the arming process, the security lamp will go OFF and the VTSS will be armed. Once the vehicle is armed the ignition may be turned to the accessory position (to listen to radio, etc.) without triggering the alarm. The VTSS can only be disarmed using the key or the RKE transmitter. Triggering the VTSS Once the VTSS is armed, the alarm will trigger if any of the doors are opened or if the key is turned the Run/Start position. When triggered, the CTM will instruct the PCM to turn OFF the engine after two seconds and will pulse the horn and headlamps at a specified duty cycle and frequency. The audible (horn) warning will continue for three minutes then terminate. The visual (headlamps) warning will continue for fifteen additional minutes then terminate. The engine will continue to start and quit until the VTSS is disarmed. Tamper Alert If the VTSS was triggered during the last armed period, the next time it is disarmed the CTM will activate three horn chirps. To determine what caused the alarm to be tripped, using the DRB select "Theft Alarm" "Monitor Display" and observe: "Alarm Tripped by". This is a great tool to Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 5496 use when a customer complains that the alarm went OFF and cannot determine what triggered it. Warnings WARNINGS Vehicle Damage Warnings Before disconnecting any control module, make sure the ignition is OFF. Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected. Road Testing A Complaint Vehicle Some complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic code or symptom condition. CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE REASSEMBLED DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB SCREEN WHILE IN MOTION.DO NOT HANG THE DRB FROM THE REAR VIEW MIRROR OR OPERATE IT YOURSELF.HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB. Wiper System WINDSHIELD WIPERS Feature Description The Ram Van equipped with a CTM will utilize speed sensitive intermittent wipe and wipe after wash function. The driver selects the Wiper function via a Steering Column mounted Stalk Switch. The Wiper system is operational whenever the ignition switch is in the Run or Accessory positions only (not during engine crank). The low and high speeds are controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as selected by the driver, and immediate wipe of the windshield takes place and the new delay interval is implemented. An Intermittent Wipe cycle consists of operating the Wipers in the Low Speed mode for one cycle, then executing a delay time. The delay time available to the driver is adjustable from 1/2 second to 18 seconds. Speed Sensitive Intermittent Wipe Operation Speed Intermittent Wipe is operational whenever the Ignition Switch is in either the RUN or ACCESSORY positions, and the voltage ON the CKT name input is greater than 4.5 VDC. The resistance selected by the stalk switch is used to set the delay time between wipe cycles. The Intermittent Wipe Delay Time is also adjusted based upon Vehicle Speed. When the Vehicle Speed is < 10 MPH then the driver selected Delay Time is doubled providing a range from 1 second to 36 seconds. When the vehicle speed is > 10 MPH then the driver selected Delay Time is not adjusted. An immediate Low Speed mode Wipe cycle will occur and a new Delay Time interval will start if the driver changes the current selected Delay Time to a shorter interval. The speed signal is provided to the CTM from the PCM over the CCD bus. Wipe after Wash Operation Wipe after Wash operation activates the Wiper system when the Wash button is pressed. Wiper after Wash operation is available while the wiper switch is OFF or in Intermittent mode, and operates the Wipers in a Low Speed continuous cycling mode while the Wash button is held on. After the Wash button is released, 2 additional complete cycles are performed at Low Speed. The Wiper system returns to the previous mode of operation following the completion of the additional Wipe cycles. Self Calibration A self calibration feature is used to eliminate performance variations due to tolerances in the resistances of the intermittent wiper switch. Following a power on reset, a default value is copied to a battery backed RAM memory location. If a valid resistance value greater than the current battery backed compensation value is measured during intermittent wiper operation, and it is present for 8 consecutive samples, the compensation value is replaced by the average of the compensation value and the new resistance value. This compensation value is used to calculate the intermittent wiper delay, using the following formula: Delay in seconds = 0.5 + 17.5* (resistance value/ compensation value) Three EEPROM locations have been provided to allow for optional calibration of the intermittent wipers. One location specifies a constant which will override the battery backed compensation value. The other locations specify constants which will override the default offset and slope used in converting resistance to time delay. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Description and Operation > Airbag System > Page 5497 Failed Wiper Park Switch A failed Wiper Park Switch is determined by the CTM "C1" PIN # 11 input remaining high for eight seconds when the wiper system is in intermittent mode. Once detected, a code flag will be set in the EEPROM fault record byte. Once the Failed Wiper Park Switch fault is set, the intermittent wiper function will not operate until a low is seen on the CTM "C1" PIN # 11 input with the ignition ON. The code flag may only be cleared manually using a DRB. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures Body Control Module: Symptom Related Diagnostic Procedures Chime Inoperative at All Times SYMPTOM * CHIME INOPERATIVE AT ALL TIMES POSSIBLE CAUSES - Chime inoperative at all times Chime Inoperative With Any Warning Lamp on SYMPTOM * CHIME INOPERATIVE WITH ANY WARNING LAMP ON POSSIBLE CAUSES - Tone request signal circuit open - Instrument cluster defective - Central Timer Module defective Chime Inoperative With Exterior Lamps On SYMPTOM * CHIME INOPERATIVE WITH EXTERIOR LAMPS POSSIBLE CAUSES - Driver door ajar switch status no change - Left door ajar switch circuit open Chime Inoperative With Key In Ignition & Driver Door Open SYMPTOM * CHIME INOPERATIVE WITH KEY IN IGNITION, DRIVER'S DOOR OPEN POSSIBLE CAUSES - Driver door switch status not changing - Key in ignition switch sense circuit open - Defective Central Timer Module - Ignition switch defective Chime Inoperative With Only One Warning Lamp SYMPTOM * CHIME INOPERATIVE WITH ONLY ONE WARNING LAMP POSSIBLE CAUSES - Oil pressure sensor defective - Oil pressure sense circuit open - Powertrain Control Module defective - Cooling system operation faulty - DRB not showing PCM active on Bus - DRB shows ECT sensor voltage too high - DRB shows ECT sensor voltage too low Chime Remains on With the Ignition on SYMPTOM * CHIME REMAINS ON WITH THE IGNITION ON POSSIBLE CAUSES - Chime staying ON with ignition ON - Tone request signal circuit short - Central Timer Module defective - Instrument cluster defective Chime Sounds With Driver's Door Open SYMPTOM * CHIME SOUNDS WITH DRIVER'S DOOR OPEN POSSIBLE CAUSES Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Body Control Module > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures > Page 5500 - Chime sounds with key removed - Key in ignition switch sense circuit short - Left front door ajar switch sense circuit short - Driver door misaligned - Central Timer Module defective Courtesy Lamp Inoperative With Left Front Door SYMPTOM * COURTESY LAMPS INOPERATIVE FROM LEFT FRONT DOOR TEST NOTE This symptom is diagnosed using the test * OPEN DRIVER DOOR AJAR.

Before attempting to diagnose or service any airbag system or related steering wheel, steering column, or instrument panel components you must first disconnect and isolate the battery negative (ground) cable. Then wait two minutes for the system capacitor to discharge before further system service. This is the only sure way to disable the airbag system. failure to do this could result in accidental airbag deployment and possible personal injury. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Dashboard / Instrument Panel > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Air Bag Disarming > Page 5593 Air Bag(s) Arming and Disarming: Service and Repair Air Bag Arming Air Bag Arming 16-Way Data Link Connector - Typical A DRB scan tool is required for diagnosis of the airbag system. See the proper Diagnostic Procedures for more information. 1. Connect the DRB scan tool to the 16-way data link wire harness connector. The connector is located on the driver side lower edge of the instrument panel, below the steering column. 2. Exit the vehicle with the DRB. Be certain that the DRB contains the latest version of the proper DRB software. 3. Connect the negative battery terminal. 4. From outside of the vehicle (away from the airbags in case of an accidental deployment) turn the ignition switch to the ON position 5. Using the DRB, read and record the active Diagnostic Trouble Code (DTC) data. 6. Read and record any stored DTC data. 7. See the proper Diagnostic Procedures if any DTC's are found. 8. After completing the necessary repairs, try to erase the stored DTC data. If any problems remain, the stored DTC data will not erase. See the proper Diagnostic Procedures for the procedures to diagnose any stored DTC that will not erase. 9. With the ignition switch still in the On position, check to be certain that nobody is in the vehicle. 10. From outside of the vehicle (away from the airbags in case of an accidental deployment) turn the ignition switch to the OFF position for about ten seconds, and then back to the ON position. Observe the airbag indicator lamp in the instrument cluster. It should light for six to eight seconds, and then go out. This indicates that the airbag system is functioning normally. NOTE: If the airbag indicator lamp fails to light, or lights and stays on, there is an airbag system malfunction. See the proper Diagnostic Procedures to diagnose the problem. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Glove Compartment > Component Information > Specifications Glove Compartment: Specifications Tighten the three screws that secure the glove box hinge to the instrument panel lower glove box opening reinforcement to 3.4 Nm (30 in. lbs.).

The RKE receiver has a memory function to retain the vehicle access codes of the RKE transmitters, even if the battery is disconnected. The power lock and RKE module can store two transmitter vehicle access codes, the CTM can store up to four. The RKE receiver is energized by one of two radio frequency inputs from the RKE transmitter, Unlock or Lock. The programming of the power lock and RKE module or the CTM responds to these RKE inputs, as well as many other inputs, by sending the proper control outputs to the power lock motors, the courtesy lamp circuit, and (with the CTM-based RKE system only) the horn relay. The RKE receiver is only serviced as a unit with the power lock and RKE module or the CTM and, if faulty or damaged, the module unit must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Locks > Keyless Entry > Keyless Entry Transmitter > Keyless Entry Transmitter Battery > Component Information > Service and Repair Keyless Entry Transmitter Battery: Service and Repair The Remote Keyless Entry (RKE) transmitter case snaps open and shut for battery access.

A power lock motor module is secured to the bottom of the door latch mounted within each front door. A power lock motor is integral to the latches used on dual side or rear doors. A separate power lock motor with a connecting link is used to actuate the latch in the sliding side or single rear door. The power lock motor direction is controlled by the battery and ground feeds from the power lock and unlock relays. The power lock and unlock relays are integral to the power lock and Remote Keyless Entry (RKE) module, or the Central Timer Module (CTM). The power door lock motors cannot be repaired and, if faulty or damaged, they must be replaced. On dual side or rear doors the entire door latch unit must be replaced. The front door, sliding side door, and single rear door power lock motors are serviced separately. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Locks > Power Locks > Power Door Lock Actuator > Component Information > Specifications > Page 5643 Power Door Lock Actuator: Testing and Inspection Before you proceed with this diagnosis, confirm proper power lock switch, power lock and Remote Keyless Entry (RKE) module or Central Timer Module (CTM), and power lock switch output circuit operation. See Power Lock Switch, and Power Lock and Remote Keyless Entry Module or Central Timer Module in the Diagnosis and Testing. Remember, the module circuitry controls the output to each of the power lock motors. 1. Check each power lock motor for correct operation while moving the power lock switch to both the Lock and Unlock positions. If all of the power lock motors are inoperative, go to Step 2. If one power lock motor is inoperative, go to Step 3. 2. If all of the power lock motors are inoperative, the problem may be caused by one shorted motor. Unplugging a shorted power lock motor from the power lock circuit will allow the good power lock motors to operate. Unplug each power lock motor wire harness connector, one at a time, and recheck both the lock and unlock functions by operating the power lock switch. If all of the power lock motors are still inoperative after the above test, check for a short or open circuit between the power lock motors and the power lock and RKE module or the CTM. If unplugging one power lock motor causes the other motor to become functional, go to Step 3 to test the unplugged motor. 3. Once it is determined which power lock motor is inoperative, that motor can be tested as follows. Unplug the wire harness connector at the inoperative power lock motor. Apply 12 volts to the motor terminals to check its operation in one direction. Reverse the polarity to check the operation in the other direction. If OK, repair the short or open circuits between the power lock motor and the power lock and RKE module or the CTM as required. If not OK, replace the faulty power lock motor. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Locks > Power Locks > Power Door Lock Actuator > Component Information > Specifications > Page 5644 Power Door Lock Actuator: Service and Repair REMOVAL Front Door 1.

The motors are connected to worm-drive gearboxes that move the seat adjuster through a combination of screw-type drive units. The front and rear of a seat are operated by different motors. They can be raised or lowered independently of each other. When the center seat switch is pushed to the Up or Down position, both the front and rear motors operate in unison, moving the entire seat up or down. The forward-rearward motor is operated by pushing the center seat switch to the Forward or Rearward position. When a switch is actuated, a battery feed and a ground path are applied through the switch contacts to the motor(s). The motor(s) and drives operate to move the seat in the selected direction until the switch is released, or until the travel limit of the power seat adjuster is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor(s) are reversed through the switch contacts. This causes the motor to run in the opposite direction. Each motor contains a self-resetting circuit breaker to protect it from overload. Consecutive or frequent resetting of the circuit breakers must not be allowed to continue, or the motors may be damaged. Make the necessary repairs. The power seat adjuster and motors cannot be repaired, and are serviced only as a complete unit. If any component in this unit is faulty or damaged, the entire power seat adjuster and motors assembly must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Seats > Power Seat Motor > Component Information > Specifications > Page 5694 Power Seat Motor: Testing and Inspection Operate the power seat switch to move all three seat motors in each direction. The seat should move in each of the selected directions. If the power seat adjuster fails to operate in only one direction move the adjuster a short distance in the opposite direction and test again to be certain that the adjuster is not at its travel limit. If the power seat adjuster still fails to operate in only one direction, see Power Seat Switch in the Diagnosis and Testing. If the power seat adjuster fails to operate in more than one direction, proceed as follows: 1. Test the circuit breaker in the junction block as described. If OK, go to Step 2. If not OK, replace the faulty circuit breaker. 2. Remove the power seat switch from the seat. Check for battery voltage at the fused B(+) circuit cavity of the power seat switch wire harness connector. If OK, go to Step 3. If not OK, repair the open circuit to the junction block as required. 3. Check for continuity between the ground circuit cavity of the power seat switch wire harness connector and a good ground. There should be continuity If OK, go to Step 4. If not OK, repair the open circuit to ground as required. 4. Test the power seat switch as described. If the switch tests OK, check the wire harness for the inoperative power seat motor(s) between the power seat switch and the motor for shorts or opens. If the circuits check OK, replace the faulty power seat adjuster and motors assembly If the circuits are not OK, repair the wire harness as required. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Seats > Power Seat Motor > Component Information > Specifications > Page 5695 Power Seat Motor: Service and Repair REMOVAL If the driver side front power seat is in the raised position, it is possible to access and remove the seat and/or the power seat adjuster and motors assembly without removing the seat riser, go to Step 6.

FIRST CLOSING CARGO DOOR (LEFT DOOR - SIDE AND/OR REAR) Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Body and Frame > Weatherstrip > Component Information > Technical Service Bulletins > Customer Interest for Weatherstrip: > 23-43-98 > Sep > 98 > Dual Cargo Door - Water Leak Diagnostic/Repair Procedure > Page 5729 1. Inspect the cavity (Figure 1) on the upper inboard corner of the molded detail and top caliper latch for a small gap. This condition can leak water into the door and/or past the weatherstrip into the vehicle interior. If a gap is found, clean the area in and around the cavity then, seal the gap with Mopar Silicone Rubber Adhesive Sealant p/n 04318025. NOTE: ALLOW THE SEALANT TO CURE FOR AT LEAST 30 MINUTES BEFORE PERFORMING A VERIFICATION WATER TEST. 2. Inspect the front lower corner of the weatherstrip seal (Figure 1) to verify seal retention. The seal is held in place by a retainer. If the retainer is missing, replace it with a new retainer p/n 03759944 or the weatherstrip seal can be secured to the door inner panel with Mopar Weatherstrip Adhesive p/n 04773774. 3. Any water that may leak into the door will exit out the door through a drain located in the lower front corner of the door. The weatherstrip seal has a small hole in the seal to allow the water exiting out of the door drain to pass through the weatherstrip seal. Inspect the drain hole of the weatherstrip seal for a clear path from the door drain to the bottom of the seal. If the drain hole in the seal is restricted, open the hole up using a sharp object. SECOND CLOSING CARGO DOOR (RIGHT SIDE DOOR - SIDE AND/OR REAR) 1.

The two switch modules are labeled: ON/OFF SET, RESUME/ACCEL, CANCEL and COAST. Refer to the owner's manual for more information on speed control switch functions and setting procedures. The individual switches cannot be repaired. If one individual switch fails, the switch module must be replaced. OPERATION Within the two switch modules, five momentary contact switches, supporting seven different speed control functions are used. The outputs from these switches are filtered into one input. The Powertrain Control Module (PCM) determines which output has been applied through resistive multiplexing. The input circuit voltage is measured by the PCM to determine which switch function has been selected. A speed control indicator lamp, located on the instrument panel cluster is energized by the PCM via the CCD Bus. This occurs when speed control system power has been turned ON, and the engine is running. SPEED CONTROL SWITCHES - PCM INPUT Six different speed control functions, using three momentary contact switches, are monitored through this multiplexed input. The resistance monitored at this input, in combination with the length of time the PCM measures the resistance, determines which switch feature has been selected. The four switches are: ON/OFF, SET/COAST, CANCEL and RESUME/ACCELERATE. Refer to Vehicle Speed Control System for further speed control information. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Cruise Control > Cruise Control Switch > Component Information > Specifications > Page 5758 Cruise Control Switch: Service and Repair SPEED CONTROL SWITCHES REMOVAL WARNING: BEFORE BEGINNING ANY AIRBAG SYSTEM COMPONENT REMOVAL OR INSTALLATION, REMOVE AND ISOLATE THE NEGATIVE (-) CABLE(S) FROM THE BATTERY.

The two switch modules are labeled: ON/OFF SET, RESUME/ACCEL, CANCEL and COAST. Refer to the owner's manual for more information on speed control switch functions and setting procedures. The individual switches cannot be repaired. If one individual switch fails, the switch module must be replaced. OPERATION Within the two switch modules, five momentary contact switches, supporting seven different speed control functions are used. The outputs from these switches are filtered into one input. The Powertrain Control Module (PCM) determines which output has been applied through resistive multiplexing. The input circuit voltage is measured by the PCM to determine which switch function has been selected. A speed control indicator lamp, located on the instrument panel cluster is energized by the PCM via the CCD Bus. This occurs when speed control system power has been turned ON, and the engine is running. SPEED CONTROL SWITCHES - PCM INPUT Six different speed control functions, using three momentary contact switches, are monitored through this multiplexed input. The resistance monitored at this input, in combination with the length of time the PCM measures the resistance, determines which switch feature has been selected. The four switches are: ON/OFF, SET/COAST, CANCEL and RESUME/ACCELERATE. Refer to Vehicle Speed Control System for further speed control information. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Cruise Control > Sensors and Switches - Cruise Control > Cruise Control Switch > Component Information > Specifications > Page 5775 Cruise Control Switch: Service and Repair SPEED CONTROL SWITCHES REMOVAL WARNING: BEFORE BEGINNING ANY AIRBAG SYSTEM COMPONENT REMOVAL OR INSTALLATION, REMOVE AND ISOLATE THE NEGATIVE (-) CABLE(S) FROM THE BATTERY.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 5800 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 5801 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 5802 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 5803 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 5804 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 5805 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number for the subsequent diagram will match a listed group shown. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 5806 Connector and Terminal Replacement 1.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 5815 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 5816 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 5817 Chime Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Page 5818 Audible Warning Device: Description and Operation CHIME SYSTEM The chime system is build into the CTM. The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for gauge problems and tell tale warnings. The CTM chime functions will have priority over the MIC chime requests. There are two chime rates, Low; 50 chimes per minute for reminders and High; 180 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the driver door is open or the headlights are left ON. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for the key-in and headlamp warning, as long as the drivers door is open. The seat belt warning chime is activated for 4 to 6 seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated. The chime will sound for the following conditions: High rate Key in Warning ignition off, key in ignition, driver's door open - Ignition off, headlamps ON, driver's door open Low rate Seat belt warning - 6 seconds after key ON (6 to 8 chimes) or until seatbelt is buckled - Airbag lamp illuminated (3 times after prove-out) - ABS lamp illuminated (2 chimes after prove-out if equipped) - Check engine lamp illuminated (2 chimes after prove-out) - Check gauges lamp illuminated (2 chimes) - Engine Temp High - when gauge enters red zone (2 chimes) - Low fuel - when fuel level reaches 1/8 tank (2 chimes) - Low washer fluid (2 chimes) - Transmission Temperature High (2 chimes) If the ignition switch is turned to the RUN/START position and the driver's door is closed, then opened, the warning chime is defeated. This allows the doors to be open without the warning chime constantly sounding. The CTM stays in this mode until the ignition switch is turned to the OFF position, then normal function will be restored. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Specifications Audible Warning Device Control Module: Specifications Tighten the three screws that secure the CTM to the inboard side of the left center instrument panel support to 2.8 Nm (25 in. lbs.). Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Specifications > Page 5822 Audible Warning Device Control Module: Locations Central Timer Module Remove/Install The CTM is mounted under the instrument panel, to the inboard side of the left center instrument panel support. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions Audible Warning Device Control Module: Diagram Information and Instructions Introduction General Information (Part 1 Of 2) Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5825 General Information (Part 2 Of 2) Chrysler wiring diagrams are designed to provide information regarding the vehicles wiring content. In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5826 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5827 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5828 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5829 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5830 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5831 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5843 Audible Warning Device Control Module: Connector Views Central Timer Module C1 Central Timer Module C2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5844 Audible Warning Device Control Module: Electrical Diagrams Central Timer Module 8w-45-2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5845 8w-45-3 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5846 8w-45-4 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5847 8w-45-5 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5848 8w-45-6 NOTE: To view sheets referred to in these diagrams, see Complete Body and Chassis Diagrams.

In addition to serving as the security system module, the CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, and a Remote Keyless Entry (RKE) module in a single unit. The CTM is also able to control and integrate many of the additional electronic functions and features included on models with this option. The CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network 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. Intermittent wipe, wipe-after-wash, and speed sensitive intermittent wipe are some of the features that the CTM supports. The intermittent wipe relay is one of the outputs that the CTM can control. The CTM is programmed to energize or de-energize the intermittent wipe relay in response to certain inputs from the windshield wiper and washer switches and from the windshield wiper motor park switch. For the speed sensitive intermittent wipe feature, the CTM also uses vehicle speed messages, which are received on the CCD data bus from the Powertrain Control Module (PCM). The CTM is mounted under the instrument panel, to the inboard side of the left center instrument panel support. For diagnosis of the CTM or the CCD data bus, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. The CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless Entry (RKE) systems. The CTM receives hard wired inputs from the power lock switches, CCD message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and coded radio frequency inputs from the RKE transmitters. In response to those and many other inputs, the internal programming of the CTM sends the proper outputs to control the power lock motors, the headlamp and horn relays, and the courtesy lamps. The RKE receiver within the CTM has a memory function to retain the vehicle access codes of at least one, but no more than four RKE transmitters. The receiver is designed to retain the transmitter codes in memory, even if the battery is disconnected. Some of the features and functions of the power lock, illuminated entry and RKE systems made possible because of the communication of the CTM on the CCD data bus network include: - A door-lock inhibit feature which prevents the power lock system from being energized with a power door lock switch if the key is in the ignition and/or the headlamps are on. However, the locks can still be operated manually, with a key, or energized with the RKE transmitter. - A delay lock feature. With the delay lock feature, if a side or rear door is still open when a lock request is received by the CTM, the module will automatically cycle all of the power lock motors to lock five seconds after the doors are closed. - An enhanced accident response feature will unlock all doors, then prevent the power door lock system from locking the doors for a predetermined time interval, after receiving a CCD message from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course, these responses are dependent upon functional battery power and wiring circuitry following the impact. - Rolling door locks is a programmable feature of the power lock system. This feature will automatically lock all of the doors and the liftgate after the vehicle reaches a speed of about 24 kilometers-per hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour). - A programmable feature of the RKE system is the enabling or disabling of the horn chirp following activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the horn chirp duration (twenty or forty milliseconds) can be selected. One of the features that the CTM supports and controls is the Vehicle Theft Security System (VTSS). In the VTSS, the CTM receives hard-wired inputs from the door ajar, front door lock cylinder, and ignition switches. The programming in the CTM allows it to process the information from these inputs and send control outputs to energize or de-energize the headlamp (or security) relay, horn relay, and the security lamp. The CTM also sends CCD data bus messages to the Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS. The CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry (RKE) systems, which are integrated into the arming, disarming, and triggering functions of the VTSS. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module > Component Information > Diagrams > Page 5852 OPERATION The Base RAM VAN body system is composed of individual modules. Because the stand-alone modules do not communicate on the CCD bus, they cannot be diagnosed using the DRB. For concerns about the Base RAM VAN, refer to the appropriate service procedures. The Base version can be identified by the sound of the Key-In Ignition BUZZER. Some of the functions and features that the CTM supports or controls include: - CCD Bus Communication - Chimes for the following conditions: Headlamps on with ignition off and driver door open warning - Key in ignition with ignition off and driver door open warning - ABS lamp illumination - Airbag lamp warning - Check gauges lamp warning - Low fuel lamp warning - Low washer fluid lamp warning - Seat belt reminder lamp warning - Transmission oil temperature lamp warning - Courtesy Lamp Controls/Illuminated Entry - Intermittent wipe control - Enhanced Accident Response - Horn chirp upon door lock with RKE (programmable) - Power lock delay - Power lock inhibit - Remote Keyless Entry (RKE) - Rolling door locks (programmable) - Speed sensitive intermittent wipe - Vehicle Theft Security System (VTSS) - Wipe after wash. The module is located on the left center instrument panel support. It contains a white 18-way and a green 14-way connector.

PC 194 CAUTION: Do not use bulbs that have a higher candle power than the bulb listed. Damage to lamp can result. Some components have lamps that can only be serviced by an Authorized Service Center (ASC) after the component is removed from the vehicle. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Description and Operation > General Information Brake Warning Indicator: Description and Operation General Information The red brake warning lamp is connected to the parking brake switch and to the pressure differential warning switch in the combination valve. The red light illuminates for approximately 2-4 seconds at engine start up. This is a self test feature designed to check bulb operation. The red warning lamp illuminates when the parking brake is applied. It also illuminates if a fluid pressure drop occurs in either the front or rear brake hydraulic circuit. A pressure drop moves the valve in the combination valve toward the low pressure side. When the valve moves it pushes the pressure differential switch contact plunger upward. This closes the contacts and completes the circuit to the lamp. The lamp will remain on until repairs are made and normal fluid pressure is restored. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Description and Operation > General Information > Page 5861 Brake Warning Indicator: Description and Operation Brake Warning Lamp Description The red brake warning lamp is used to alert the driver of a hydraulic fault or that the parking brake is applied. For the RWAL system, the red brake warning lamp also is used to alerts the driver of a problem with the RWAL system. The brake warning lamp illuminates when a message is sent over the bus to the cluster to illuminate the bulb. A ground for the bulb is provided when: The brakes are applied and the park brake switch is actuated. - A hydraulic fault has occurred and the pressure differential switch is actuated. - A RWAL fault has occurred. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Description and Operation > Page 5862 Brake Warning Indicator: Testing and Inspection HARD WIRED LAMP DIAGNOSIS Each of the lamps depends upon a hard wired circuit input to the instrument cluster for proper operation.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 5869 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 5870 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 5871 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 5872 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 5873 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 5874 Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

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 in 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 and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 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. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 5884 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. 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 every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. 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 fuse circuit. 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 the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 5885 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Page 5886 Cigarette Lighter: Service Precautions WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO RESTRAINT SYSTEMS / AIRBAG SYSTEMS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The cigar lighter is installed in the instrument panel accessory switch plate, which is located near the center of the instrument panel, inboard of the radio. The cigar lighter base is secured by a snap fit within the instrument panel accessory switch plate. The cigar lighter knob and heating element unit, and the cigar lighter receptacle unit are available for service. These components cannot be repaired and, if faulty or damaged, they must be replaced. OPERATION The cigar lighter consists of two major components: a knob and heating element unit, and the cigar lighter base or receptacle 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 junction block only when the ignition switch is in the Accessory or On positions. The 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 receptacle shell, the heating element resistor coil is grounded through its housing to the receptacle 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 receptacle shell. Two small spring-clip retainers are located on either side of the insulated contact inside the bottom of the receptacle 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 receptacle shell, the protective heat shield slides downward on the housing so that the heating element is recessed and shielded around its circumference for safety. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Page 5889 Cigarette Lighter: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The fuel pump module contains the following components: - A combination fuel filter/fuel pressure regulator - Electric fuel pump - Fuel pump reservoir - A separate fuel pick-up filter (strainer) - Fuel gauge sending unit (fuel level sensor) - Fuel supply line connection at filter/regulator - A plastic threaded locknut to retain pump module to fuel tank - A gasket between tank flange and module The fuel gauge sending unit (fuel level sensor), and pick-up filter (at bottom of module) may be serviced separately. If the electrical fuel pump requires service, the entire fuel pump module must be replaced. The fuel filter/fuel pressure regulator may be serviced separately. Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for additional information. FUEL GAUGE SENDING UNIT 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). The resistor track is used to send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for OBD II emission requirements. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge Sender > Component Information > Specifications > Page 5909 For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and arm move down. This increases the sending unit resistance causing the fuel gauge to read empty. After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading. For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the sending unit to the PCM 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 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 Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge Sender > Component Information > Specifications > Page 5910 Fuel Gauge Sender: Testing and Inspection The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down, electrical resistance will change. Refer to Instrument Panel and Gauges for Fuel Gauge testing. To test the gauge sending unit only, it must be removed from vehicle. The unit is part of the fuel pump module. Refer to Fuel Pump Module Removal/ Installation for procedures. Measure the resistance across the sending unit terminals.

When the park or head lamps are turned on, the cluster illumination lamps light. Illumination brightness is adjusted by rotating the headlamp switch knob (clockwise to dim, counterclockwise to brighten). The instrument cluster illumination lamps receive battery feed from the panel dimmer rheostat in the headlamp switch through a fuse in the junction block. The instrument cluster electronic circuitry also monitors the cluster illumination lamp dimming level whenever the park or head lamps are turned on. The instrument cluster electronic circuitry responds by adjusting the dimming level of the odometer Vacuum Fluorescent Display (VFD), and sending dimming level messages over the Chrysler Collision Detection (CCD) data bus network. When the park lamps or headlamps are turned off, the VFD is illuminated at full brightness for improved daylight visibility. Each of the cluster illumination lamps is located on the instrument cluster circuit board. Each cluster illumination lamp has a replaceable bulb and bulb holder. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Instrument Cluster / Carrier > Instrument Panel Bulb > Component Information > Locations > Page 5929 Instrument Panel Bulb: Testing and Inspection HARD WIRED LAMP DIAGNOSIS Each of the lamps depends upon a hard wired circuit input to the instrument cluster for proper operation. The following procedures will help to diagnose conditions that may cause an inoperative hard wired lamp circuit condition. WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. Cluster Illumination Lamp The diagnosis found here addresses an inoperative instrument cluster illumination lamp condition. If the problem being diagnosed includes inoperative exterior lighting controlled by the headlamp switch, that system needs to be repaired first. If the exterior lamps controlled by the headlamp switch are inoperative, refer to Headlamp Diagnosis in the Diagnosis and Testing of Lamps for diagnosis. If no exterior lighting system problems are found, the following procedure will help locate a short or open in the cluster illumination lamp circuit. If the problem being diagnosed involves a lack of dimming control for the odometer/trip odometer Vacuum Fluorescent Display (VFD), but all of the other cluster illumination lamps can be dimmed, repair the open headlamp switch output circuit input to the instrument cluster. 1. Check the panel lamps dimmer fuse in the junction block. If OK, go to Step 2. If not OK, repair the shorted circuit or component as required and replace the faulty fuse. 2. Turn the park lamps on with the headlamp switch. Rotate the headlamp switch knob counterclockwise to just before the interior lamps detent. Check for battery voltage at the panel lamps dimmer fuse in the junction block. Rotate the headlamp switch knob clockwise while observing the test voltmeter. The reading should go from battery voltage to zero volts. If OK, go to Step 3. If not OK, repair the open panel lamps dimmer switch signal circuit to the headlamp switch as required. If the circuit tests OK, refer to Headlamp Diagnosis in the Diagnosis and Testing of Lamps to diagnose the headlamp switch. 3. Disconnect and isolate the battery negative cable. Remove the instrument cluster. Turn the headlamp switch off. Remove the panel lamps dimmer fuse from the junction block. Probe the fused panel lamps dimmer switch signal circuit cavity of the instrument cluster wire harness connector B. Check for continuity to a good ground. There should be no continuity. If OK, go to Step 4. If not OK, repair the shorted fused panel lamps dimmer switch signal circuit as required. 4. Install the panel lamps dimmer fuse in the junction block. Connect the battery negative cable. Turn the park lamps on with the headlamp switch. Rotate the headlamp switch knob counterclockwise to just before the interior lamps detent. Check for battery voltage at the fused panel lamps dimmer switch signal circuit cavity of the instrument cluster wire harness connector B. If OK, replace the faulty cluster illumination lamp bulb(s) and bulb holder(s). If not OK, repair the open fused panel lamps dimmer switch signal circuit as required. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Instrument Cluster / Carrier > Instrument Panel Bulb > Component Information > Locations > Page 5930 Instrument Panel Bulb: Service and Repair Some of the components for the instrument cluster used in this vehicle are serviced individually.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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. Circuit Function Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5959 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5960 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information 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 In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5961 - 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 connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (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, especially 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 from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5962 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5963 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5976 Audible Warning Device Control Module: Connector Views Central Timer Module C1 Central Timer Module C2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5977 Audible Warning Device Control Module: Electrical Diagrams Central Timer Module 8w-45-2 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5978 8w-45-3 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5979 8w-45-4 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5980 8w-45-5 Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 5981 8w-45-6 NOTE: To view sheets referred to in these diagrams, see Complete Body and Chassis Diagrams.

In addition to serving as the security system module, the CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, and a Remote Keyless Entry (RKE) module in a single unit. The CTM is also able to control and integrate many of the additional electronic functions and features included on models with this option. The CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network 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. Intermittent wipe, wipe-after-wash, and speed sensitive intermittent wipe are some of the features that the CTM supports. The intermittent wipe relay is one of the outputs that the CTM can control. The CTM is programmed to energize or de-energize the intermittent wipe relay in response to certain inputs from the windshield wiper and washer switches and from the windshield wiper motor park switch. For the speed sensitive intermittent wipe feature, the CTM also uses vehicle speed messages, which are received on the CCD data bus from the Powertrain Control Module (PCM). The CTM is mounted under the instrument panel, to the inboard side of the left center instrument panel support. For diagnosis of the CTM or the CCD data bus, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. The CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless Entry (RKE) systems. The CTM receives hard wired inputs from the power lock switches, CCD message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and coded radio frequency inputs from the RKE transmitters. In response to those and many other inputs, the internal programming of the CTM sends the proper outputs to control the power lock motors, the headlamp and horn relays, and the courtesy lamps. The RKE receiver within the CTM has a memory function to retain the vehicle access codes of at least one, but no more than four RKE transmitters. The receiver is designed to retain the transmitter codes in memory, even if the battery is disconnected. Some of the features and functions of the power lock, illuminated entry and RKE systems made possible because of the communication of the CTM on the CCD data bus network include: - A door-lock inhibit feature which prevents the power lock system from being energized with a power door lock switch if the key is in the ignition and/or the headlamps are on. However, the locks can still be operated manually, with a key, or energized with the RKE transmitter. - A delay lock feature. With the delay lock feature, if a side or rear door is still open when a lock request is received by the CTM, the module will automatically cycle all of the power lock motors to lock five seconds after the doors are closed. - An enhanced accident response feature will unlock all doors, then prevent the power door lock system from locking the doors for a predetermined time interval, after receiving a CCD message from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course, these responses are dependent upon functional battery power and wiring circuitry following the impact. - Rolling door locks is a programmable feature of the power lock system. This feature will automatically lock all of the doors and the liftgate after the vehicle reaches a speed of about 24 kilometers-per hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour). - A programmable feature of the RKE system is the enabling or disabling of the horn chirp following activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the horn chirp duration (twenty or forty milliseconds) can be selected. One of the features that the CTM supports and controls is the Vehicle Theft Security System (VTSS). In the VTSS, the CTM receives hard-wired inputs from the door ajar, front door lock cylinder, and ignition switches. The programming in the CTM allows it to process the information from these inputs and send control outputs to energize or de-energize the headlamp (or security) relay, horn relay, and the security lamp. The CTM also sends CCD data bus messages to the Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS. The CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry (RKE) systems, which are integrated into the arming, disarming, and triggering functions of the VTSS. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Page 5985 OPERATION The Base RAM VAN body system is composed of individual modules. Because the stand-alone modules do not communicate on the CCD bus, they cannot be diagnosed using the DRB. For concerns about the Base RAM VAN, refer to the appropriate service procedures. The Base version can be identified by the sound of the Key-In Ignition BUZZER. Some of the functions and features that the CTM supports or controls include: - CCD Bus Communication - Chimes for the following conditions: Headlamps on with ignition off and driver door open warning - Key in ignition with ignition off and driver door open warning - ABS lamp illumination - Airbag lamp warning - Check gauges lamp warning - Low fuel lamp warning - Low washer fluid lamp warning - Seat belt reminder lamp warning - Transmission oil temperature lamp warning - Courtesy Lamp Controls/Illuminated Entry - Intermittent wipe control - Enhanced Accident Response - Horn chirp upon door lock with RKE (programmable) - Power lock delay - Power lock inhibit - Remote Keyless Entry (RKE) - Rolling door locks (programmable) - Speed sensitive intermittent wipe - Vehicle Theft Security System (VTSS) - Wipe after wash. The module is located on the left center instrument panel support. It contains a white 18-way and a green 14-way connector.

The fuel pump module is located inside of fuel tank. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Specifications > Page 5999 Fuel Gauge Sender: Description and Operation FUEL PUMP MODULE Top View of Fuel Pump Module Fuel Pump Module Components (Typical Pump Module Shown) The fuel pump module on all models is installed in the top of the fuel tank. The fuel pump module contains the following components: - A combination fuel filter/fuel pressure regulator - Electric fuel pump - Fuel pump reservoir - A separate fuel pick-up filter (strainer) - Fuel gauge sending unit (fuel level sensor) - Fuel supply line connection at filter/regulator - A plastic threaded locknut to retain pump module to fuel tank - A gasket between tank flange and module The fuel gauge sending unit (fuel level sensor), and pick-up filter (at bottom of module) may be serviced separately. If the electrical fuel pump requires service, the entire fuel pump module must be replaced. The fuel filter/fuel pressure regulator may be serviced separately. Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for additional information. FUEL GAUGE SENDING UNIT 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). The resistor track is used to send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for OBD II emission requirements. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Specifications > Page 6000 For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and arm move down. This increases the sending unit resistance causing the fuel gauge to read empty. After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading. For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the sending unit to the PCM 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 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 Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Specifications > Page 6001 Fuel Gauge Sender: Testing and Inspection The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down, electrical resistance will change. Refer to Instrument Panel and Gauges for Fuel Gauge testing. To test the gauge sending unit only, it must be removed from vehicle. The unit is part of the fuel pump module. Refer to Fuel Pump Module Removal/ Installation for procedures. Measure the resistance across the sending unit terminals.

The mechanical gear selector indicator gives an indication of the transmission gear that has been selected with the automatic transmission gear selector lever. The indicator housing is mounted to the rear of the instrument cluster housing. The gear selector indicator pointer is easily visible through an opening provided in the front of the instrument cluster mask, and is also lighted by the cluster illumination lamps for visibility at night. This information covers only the removal and installation of the gear selector indicator from the instrument cluster. OPERATION The gear selector indicator has a spring-loaded pointer that is mechanically actuated by a cable connected to the gear selector indicator driver lever of the gear selector lever mechanism on the steering column. When the gear selector lever is moved the indicator driver lever moves, which actuates the spring-loaded pointer through the mechanical actuator cable. An adjuster mounted on the steering column housing provides a mechanical means of calibrating the gear selector indicator mechanism. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Transmission Shift Position Indicator Lamp > Component Information > Specifications > Page 6017 Transmission Shift Position Indicator Lamp: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The combination flasher contains active electronic Integrated Circuitry (IC) elements. This flasher is designed to handle the current flow requirements of the factory-installed lighting. If supplemental lighting is added to the turn signal lamp circuits, such as when towing a trailer with lights, the combination flasher will automatically try to compensate to keep the flash rate the same. While the combination flasher has an International Standards Organization (ISO)-type relay terminal configuration or footprint, the internal circuitry is much different. The combination flasher does not use standard ISO-relay inputs or provide ISO-relay type outputs or functions. The combination flasher should never be substituted for an ISO-relay or replaced with an ISO-relay, or else component and vehicle damage may occur. Because of the active electronic elements within the combination flasher, it cannot be tested with conventional automotive electrical test equipment. If the combination flasher is believed to be faulty, test the turn signal system and hazard warning system circuits as described. Then replace the combination flasher with a known good unit to confirm system operation. The combination flasher has five blade-type terminals intended for the following inputs and outputs: fused B(+), fused ignition switch output, ground, turn signal circuit, and hazard warning circuit. Constant battery voltage and ground are supplied to the flasher so that it can perform the hazard warning function, and ignition switched battery voltage is supplied for the turn signal function. The combination flasher is located in the junction block behind the end cap on the left end of the instrument panel. The combination flasher cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION Combination Flasher - Typical The IC within the combination flasher contains the logic that controls the flasher operation and the flash rate. Pin 6 of the IC receives a sense voltage from the hazard warning circuit of the multi-function switch. When the hazard warning switch is turned on, the "hazard on sense" voltage will become low due to the circuit being grounded through the turn signal bulbs. This low voltage sense signals the IC to energize the flash control Positive - Negative - Positive (PNP) transistor at a pre-calibrated flash rate or frequency. Each time the PNP transistor energizes the hazard warning circuit, the pin 6 "hazard on sense" voltage will become high and the IC signals the PNP transistor to de-energize the circuit. This cycling will continue until the hazard warning switch is turned off. Likewise, pin 8 of the IC receives a sense voltage from the turn signal circuits of the multi-function switch. When the left or right turn signal switch is turned on, the "turn signal on sense' voltage will become low due to the circuit being grounded through the turn signal bulbs. This low voltage sense signals the IC to energize the flash control PNP transistor at a pre-calibrated flash rate or frequency. Each time the PNP transistor energizes the turn signal circuit, the pin 8 "turn signal on sense" voltage will become high and the IC signals the PNP transistor to de-energize the circuit. This cycling will continue until the right or left turn signal switch is turned off. A special design feature of the combination flasher allows it to "sense" that a turn signal circuit or bulb is not operating, and provide the driver an indication of the condition by flashing the remaining bulbs in the affected circuit at a higher rate (120 flashes-per-minute or higher). Conventional flashers either continue flashing at their typical rate (heavy-duty type), or discontinue flashing the affected circuit entirely (standard-duty type). During turn signal operation, the combination flasher IC compares normal battery voltage input on pin 2 with the shunt resistor voltage input on pin 7. If the IC "senses" that the voltage difference between pin 2 and pin 7 is different than the pre-calibrated value of the IC, it will increase the rate at which it signals the PNP transistor to energize the pin 1 output. Thus, the inoperative half (left or right side) of the turn signal circuit will flash faster. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Locations > Page 6090 Hazard Warning Flasher: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The terminal designations and functions are the same as a conventional International Standards Organization (ISO) relay. The horn relay is a electromechanical device that switches battery current to the horn when the horn switch grounds the relay coil. The horn relay is located in the junction block on the driver side end of the instrument panel in the passenger compartment. If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the junction block until further diagnosis is completed. The horn relay is an ISO micro-relay. Relays confirming to the ISO specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions. 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 horn relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION 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 the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Lighting and Horns > Horn > Horn Relay > Component Information > Locations > Page 6134 Horn Relay: Testing and Inspection Horn Relay The horn relay is located in the junction block on the driver side end of the instrument panel in the passenger compartment.

The switch consists of two plastic membranes, one that is flat and one that is slightly convex. These two membranes are secured to each other around the perimeter. Inside the switch, the centers of the facing surfaces of these membranes each has a grid made with an electrically conductive material applied to it. One of the grids is connected to a circuit that provides it with continuity to ground at all times. The grid of the other membrane is connected to the horn relay control circuit. The steering wheel and steering column must be properly grounded in order for the horn switch to function properly. The horn switch is only serviced as a part of the driver side airbag module trim cover. If the horn switch is damaged or faulty, or if the driver side airbag is deployed, the driver side airbag module trim cover and horn switch must be replaced as a unit. OPERATION When the center area of the driver side airbag trim cover is depressed, the electrically conductive grids on the facing surfaces of the horn switch membranes contact each other, closing the switch circuit. The completed horn switch circuit provides a ground for the control coil side of the horn relay, which activates the relay. When the horn switch is released, the resistive tension of the convex membrane separates the two electrically conductive grids and opens the switch circuit. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Lighting and Horns > Horn > Horn Switch > Component Information > Service Precautions > Page 6140 Horn Switch: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The terminal designations and functions are the same as a conventional International Standards Organization (ISO) relay. The horn relay is a electromechanical device that switches battery current to the horn when the horn switch grounds the relay coil. The horn relay is located in the junction block on the driver side end of the instrument panel in the passenger compartment. If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the junction block until further diagnosis is completed. The horn relay is an ISO micro-relay. Relays confirming to the ISO specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions. 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 horn relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION 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 the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Horn Relay > Component Information > Locations > Page 6186 Horn Relay: Testing and Inspection Horn Relay The horn relay is located in the junction block on the driver side end of the instrument panel in the passenger compartment.

The switch consists of two plastic membranes, one that is flat and one that is slightly convex. These two membranes are secured to each other around the perimeter. Inside the switch, the centers of the facing surfaces of these membranes each has a grid made with an electrically conductive material applied to it. One of the grids is connected to a circuit that provides it with continuity to ground at all times. The grid of the other membrane is connected to the horn relay control circuit. The steering wheel and steering column must be properly grounded in order for the horn switch to function properly. The horn switch is only serviced as a part of the driver side airbag module trim cover. If the horn switch is damaged or faulty, or if the driver side airbag is deployed, the driver side airbag module trim cover and horn switch must be replaced as a unit. OPERATION When the center area of the driver side airbag trim cover is depressed, the electrically conductive grids on the facing surfaces of the horn switch membranes contact each other, closing the switch circuit. The completed horn switch circuit provides a ground for the control coil side of the horn relay, which activates the relay. When the horn switch is released, the resistive tension of the convex membrane separates the two electrically conductive grids and opens the switch circuit. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Horn Switch > Component Information > Service Precautions > Page 6235 Horn Switch: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

OPERATION The multi-function switch control stalk that extends from the left side of the steering column just below the steering wheel is moved up or down to activate the turn signal switch. When the control stalk is moved in the upward direction, the right turn signal switch circuitry is activated; and, when the control stalk is moved in the downward direction, the left turn signal switch circuitry is activated. 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 multi-function switch control stalk is released. When the turn signal switch is in a detent position, it is turned off by a turn signal cancel cam located on the steering column upper shaft below the shaft lock shield and the clockspring mechanism. Turning the steering wheel causes the cancel cam lobes to contact a cancel actuator in the multi-function switch, and the turn signal switch automatically returns to the off position. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Turn Signal Switch > Component Information > Specifications > Page 6241 Turn Signal Switch: Testing and Inspection The turn signal switch and the hazard warning switch are integral to the multi-function switch.

The combination flasher contains active electronic Integrated Circuitry (IC) elements. This flasher is designed to handle the current flow requirements of the factory-installed lighting. If supplemental lighting is added to the turn signal lamp circuits, such as when towing a trailer with lights, the combination flasher will automatically try to compensate to keep the flash rate the same. While the combination flasher has an International Standards Organization (ISO)-type relay terminal configuration or footprint, the internal circuitry is much different. The combination flasher does not use standard ISO-relay inputs or provide ISO-relay type outputs or functions. The combination flasher should never be substituted for an ISO-relay or replaced with an ISO-relay, or else component and vehicle damage may occur. Because of the active electronic elements within the combination flasher, it cannot be tested with conventional automotive electrical test equipment. If the combination flasher is believed to be faulty, test the turn signal system and hazard warning system circuits as described. Then replace the combination flasher with a known good unit to confirm system operation. The combination flasher has five blade-type terminals intended for the following inputs and outputs: fused B(+), fused ignition switch output, ground, turn signal circuit, and hazard warning circuit. Constant battery voltage and ground are supplied to the flasher so that it can perform the hazard warning function, and ignition switched battery voltage is supplied for the turn signal function. The combination flasher is located in the junction block behind the end cap on the left end of the instrument panel. The combination flasher cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION Combination Flasher - Typical The IC within the combination flasher contains the logic that controls the flasher operation and the flash rate. Pin 6 of the IC receives a sense voltage from the hazard warning circuit of the multi-function switch. When the hazard warning switch is turned on, the "hazard on sense" voltage will become low due to the circuit being grounded through the turn signal bulbs. This low voltage sense signals the IC to energize the flash control Positive - Negative - Positive (PNP) transistor at a pre-calibrated flash rate or frequency. Each time the PNP transistor energizes the hazard warning circuit, the pin 6 "hazard on sense" voltage will become high and the IC signals the PNP transistor to de-energize the circuit. This cycling will continue until the hazard warning switch is turned off. Likewise, pin 8 of the IC receives a sense voltage from the turn signal circuits of the multi-function switch. When the left or right turn signal switch is turned on, the "turn signal on sense' voltage will become low due to the circuit being grounded through the turn signal bulbs. This low voltage sense signals the IC to energize the flash control PNP transistor at a pre-calibrated flash rate or frequency. Each time the PNP transistor energizes the turn signal circuit, the pin 8 "turn signal on sense" voltage will become high and the IC signals the PNP transistor to de-energize the circuit. This cycling will continue until the right or left turn signal switch is turned off. A special design feature of the combination flasher allows it to "sense" that a turn signal circuit or bulb is not operating, and provide the driver an indication of the condition by flashing the remaining bulbs in the affected circuit at a higher rate (120 flashes-per-minute or higher). Conventional flashers either continue flashing at their typical rate (heavy-duty type), or discontinue flashing the affected circuit entirely (standard-duty type). During turn signal operation, the combination flasher IC compares normal battery voltage input on pin 2 with the shunt resistor voltage input on pin 7. If the IC "senses" that the voltage difference between pin 2 and pin 7 is different than the pre-calibrated value of the IC, it will increase the rate at which it signals the PNP transistor to energize the pin 1 output. Thus, the inoperative half (left or right side) of the turn signal circuit will flash faster. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Locations > Page 6259 Turn Signal Flasher: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The only visible parts of the multi-function switch are the control stalk that extends from the left side of the steering column, and the hazard warning switch push button that protrudes from the top of the steering column. The multi-function switch control stalk has both nomenclature and international control symbols on it, which identify its many functions. The hazard warning switch push button is identified with a double triangle, which is the international control symbol for hazard warning. The remainder of the multi-function switch is concealed beneath the steering column shrouds. The multi-function switch also contains circuitry for the following functions: Headlamp beam selection - Headlamp optical horn - Horn contact and circuit - Windshield wipers - Windshield washers. The information contained addresses only the multi-function switch turn signal and hazard warning functions. However, the turn signal and hazard warning switches cannot be repaired. if these switches or any other circuit or component of the multi-function switch unit is faulty or damaged, the entire multi-function switch unit must be replaced. OPERATION The multi-function switch control stalk that extends from the left side of the steering column just below the steering wheel is moved up or down to activate the turn signal switch. When the control stalk is moved in the upward direction, the right turn signal switch circuitry is activated; and, when the control stalk is moved in the downward direction, the left turn signal switch circuitry is activated. 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 multi-function switch control stalk is released. When the turn signal switch is in a detent position, it is turned off by a turn signal cancel cam located on the steering column upper shaft below the shaft lock shield and the clockspring mechanism. Turning the steering wheel causes the cancel cam lobes to contact a cancel actuator in the multi-function switch, and the turn signal switch automatically returns to the off position. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Switch > Component Information > Specifications > Page 6276 Turn Signal Switch: Testing and Inspection The turn signal switch and the hazard warning switch are integral to the multi-function switch.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, 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 page, and the ground (B-) side of the circuit is placed near the bottom of the page. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate the page where the component is shown complete. 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.

Troubleshooting Tools 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 - This instrument is 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 vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. 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 non-factory 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. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Windows and Glass > Rear Window Defogger <--> [Heated Glass Element] > Component Information > Diagrams > Page 6314 Rear Window Defogger: Service Precautions WARNING: - ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

Rear Window Defogger System The rear window defogger system will only operate when the ignition switch is in the On position. When the defogger switch is in the On position, an electric heater grid on the rear window glass is energized. The electric heater grid produces heat to help clear the rear window glass of ice, snow, or fog. The defogger system is controlled by a momentary switch that is integral to the heater and air conditioner control assembly, which is located below the radio in the instrument cluster bezel on the instrument panel. An amber indicator lamp above the switch will light to indicate when the defogger system is turned on. The heater and air conditioner control assembly also contains the defogger system timer and logic circuitry, and an integral defogger relay The defogger system will be automatically turned off after a programmed time interval of about ten minutes. After the initial time interval has expired, if the defogger switch is turned on again during the same ignition cycle, the defogger system will automatically turn off after about five minutes. The defogger system will automatically shut off if the ignition switch is turned to the Off position, or it can be turned off manually by depressing the defogger switch again. Following are general descriptions of the major components in the rear window defogger system. Refer to the owner's manual in the vehicle glove box for more information on the features, use and operation of the rear window defogger system. SYSTEM OPERATION Rear Glass Heating Grid The heated rear window glass has two electrically conductive vertical bus bars and a series of horizontal grid lines made of a silver-ceramic material, which is baked on and bonded to the inside surface of the glass. The grid lines and bus bars comprise a parallel electrical circuit. When the rear window defogger switch is placed in the On position, electrical current is directed to the rear window grid lines through the bus bars. The grid lines heat the rear window to clear the surface of fog or snow. Protection for the heating grid circuit is provided by a fuse in the Power Distribution Center (PDC). The grid lines and bus bars are highly resistant to abrasion. However, it is possible for an open circuit to occur in an individual grid line, resulting in no current flow through the line. The grid lines can be damaged or scraped off with sharp instruments. Care should be taken when cleaning the glass or removing foreign materials, decals, or stickers from the glass. Normal glass cleaning solvents or hot water used with rags or toweling is recommended. A repair kit is available to repair the grid lines and bus bars, or to reinstall the heated glass terminals. Rear Window Defogger System Control The rear window defogger switch, rear window defogger indicator lamp, rear window defogger mirror electronic timer/control/logic circuitry and rear window defogger relay are all integral to the heater and air conditioner control assembly, which is located below the radio in the instrument cluster bezel on the instrument panel. The momentary-type switch provides a hard wired battery signal to the electronic circuitry each time it is depressed. An amber rear window defogger indicator lamp above the rear window defogger switch lights to indicate when the rear window defogger system is turned On. The rear window defogger electronic timer/control/ logic circuitry responds to the switch input by energizing or de-energizing the rear window defogger relay. Energizing the rear window defogger relay provides electrical current to the rear glass heating grid. The rear window defogger switch, rear window defogger indicator lamp, rear window defogger electronic timer/control/logic circuitry and rear window defogger relay cannot be repaired. If damaged or faulty, the entire heater and air conditioner control assembly must be replaced. Refer to Heater-A/C Control in the Replacement of Heating and Air Conditioning/Control Assembly for the service procedures. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Windows and Glass > Rear Window Defogger <--> [Heated Glass Element] > Component Information > Testing and Inspection > Detecting Breaks in Rear Window Defogger Grid Rear Window Defogger: Testing and Inspection Detecting Breaks in Rear Window Defogger Grid To detect breaks in the grid lines, the following procedure is required: 1. Turn the ignition switch to the On position. Set the defogger switch in the On position. The indicator lamp should light. If OK, go to Step 2. If not OK, see Rear Window Defogger System Control in the Diagnosis and Testing. 2. Using a 12-volt DC voltmeter, contact the vertical bus bar on the right side of the vehicle with the negative lead. With the positive lead, contact the vertical bus bar on the left side of the vehicle. The voltmeter should read battery voltage. If OK, go to Step 3. If not OK, repair the open circuit to the rear window defogger system control as required. 3. With the negative lead of the voltmeter, contact a good body ground point. The voltage reading should not change. If OK, go to Step 4. If not OK, repair the circuit to ground as required. 4. Connect the negative lead of the voltmeter to the right side bus bar and touch each grid line at midpoint C with the positive lead. A reading of approximately six volts indicates a line is good. A reading of zero volts indicates a break in the grid line between midpoint C and the left side bus bar. A reading of ten to fourteen volts indicates a break between midpoint C and the right side bus bar. Move the positive lead on the grid line towards the break and the voltage reading will change as soon as the break is crossed. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Windows and Glass > Rear Window Defogger <--> [Heated Glass Element] > Component Information > Testing and Inspection > Detecting Breaks in Rear Window Defogger Grid > Page 6318 Rear Window Defogger: Testing and Inspection Defogger System Operation Check WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. The operation of the electrically heated rear window defogger system can be confirmed in one of the following manners: 1. Turn the ignition switch to the On position. While monitoring the instrument panel voltmeter, set the defogger switch in the On position. When the defogger switch is turned On, a distinct voltmeter needle deflection should be noted. 2. Turn the ignition switch to the On position. Set the defogger switch in the On position. The rear window defogger operation can be checked by feeling the rear window glass. A distinct difference in temperature between the grid lines and the adjacent clear glass can be detected within three to four minutes of operation. Rear Window Glass Grid Test 3. Using a 12-volt DC voltmeter, contact the rear glass heating grid terminal A (right side) with the negative lead, and terminal B (left side) with the positive lead. The voltmeter should read battery voltage. The above checks will confirm system operation. Illumination of the defogger switch indicator lamp means that there is electrical current available at the output of the rear window defogger logic and timer circuitry, but does not confirm that the electrical current is reaching the rear glass heating grid lines. If the defogger system does not operate, the problem should be isolated in the following manner: 1. Confirm that the ignition switch is in the On position. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Windows and Glass > Rear Window Defogger <--> [Heated Glass Element] > Component Information > Testing and Inspection > Detecting Breaks in Rear Window Defogger Grid > Page 6319 Rear Window Defogger System 2. Ensure that the rear glass heating grid feed and ground wires are connected to the glass. Confirm that the ground wire has continuity to ground, and that there is continuity between the electrical contacts in the rear door hinge pillar when the rear door is closed. 3. Check the fuses in the Power Distribution Center (PDC) and in the junction block. The fuses must be tight in their receptacles and all electrical connections must be secure. When the above steps have been completed and the rear glass heating grid is still inoperative, one or more of the following is faulty: - Defogger system control - Rear window grid lines (all grid lines would have to be broken or one of the feed wires disconnected for the entire system to be inoperative). If setting the defogger switch to the On position produces a severe voltmeter deflection, check for a short circuit between the rear window defogger system control output and the rear glass heating grid. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Windows and Glass > Rear Window Defogger <--> [Heated Glass Element] > Component Information > Testing and Inspection > Detecting Breaks in Rear Window Defogger Grid > Page 6320 Rear Window Defogger: Testing and Inspection Defogger System Testing WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

In addition to low and high speed, the intermittent wipe system has a delay mode. Electronic circuitry within the intermittent wipe module is used to accomplish the wiper delay mode. The delay time selected by the driver has a range of from about one-half second to about eighteen seconds. The driver selects the length of the delay by placing the wiper (multi-function) switch knob in one of five different intermittent wipe detent positions. One of the detent positions sends a battery voltage signal to the intermittent wipe module, while the other four positions use resistors to provide progressively lower voltage signals to the module. If the washer knob is depressed while the wiper switch is in the Off position, the intermittent wipe module will operate the wiper motor for approximately three wipes and automatically turn off the motor. The intermittent wipe module is snap-fit onto a single blade-type mounting bracket located on the instrument panel reinforcement above the glove box opening. The intermittent wipe module cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Wiper and Washer Systems > Relays and Modules - Wiper and Washer Systems > Wiper Control Module > Component Information > Service Precautions > Page 6357 Wiper Control Module: Testing and Inspection Intermittent Wiper Module Testing The intermittent wipe module is used on vehicles that are not equipped with the Vehicle Theft Security System (VTSS).

In addition to low and high speed, the intermittent wipe system has a delay mode. Electronic circuitry within the intermittent wipe module is used to accomplish the wiper delay mode. The delay time selected by the driver has a range of from about one-half second to about eighteen seconds. The driver selects the length of the delay by placing the wiper (multi-function) switch knob in one of five different intermittent wipe detent positions. One of the detent positions sends a battery voltage signal to the intermittent wipe module, while the other four positions use resistors to provide progressively lower voltage signals to the module. If the washer knob is depressed while the wiper switch is in the Off position, the intermittent wipe module will operate the wiper motor for approximately three wipes and automatically turn off the motor. The intermittent wipe module is snap-fit onto a single blade-type mounting bracket located on the instrument panel reinforcement above the glove box opening. The intermittent wipe module cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Ram 1500 Van Workshop Manual (V8-5.2L VIN Y (1999)) Dodge Workshop Manuals > Wiper and Washer Systems > Wiper Control Module > Component Information > Service Precautions > Page 6441 Wiper Control Module: Testing and Inspection Intermittent Wiper Module Testing The intermittent wipe module is used on vehicles that are not equipped with the Vehicle Theft Security System (VTSS).
