The actual wiring of each system circuit is shown from the point where the power source is received from the battery as far as each ground point. (All circuit diagrams are shown with the switches in the OFF position.) When troubleshooting any problem, first understand the operation of the circuit where the problem was detected (see System Circuit section), the power source supplying power to that circuit (see Power Source section), and the ground points (see Ground Point section). See the System Outline to understand the circuit operation. When the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing sections to find each part, junction block and wiring harness connectors, wiring harness and wiring harness connectors, splice points, and ground points of each system circuit. Internal wiring for each junction block is also provided for better understanding of connection within a junction block. Wiring related to each system is indicated in each system circuit by arrows (from__, to__). When overall connections are required, see the Overall Electrical Wiring Diagram at the end of this manual. 3 B HOW TO USE THIS MANUAL ∗ The system shown here is an EXAMPLE ONLY.

[M] : Page No. 5 B HOW TO USE THIS MANUAL [N] System Outline Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW. When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows through the rear lights warning light to TERMINAL 4 of the light failure sensor. Stop Light Disconnection Warning When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the disconnection and the warning circuit of the light failure sensor is activated. As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lights warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning circuit on and holds the warning light on until the ignition SW is turned off. [O] Service Hints S6 Stop Light SW 2–1 : Closed with the brake pedal depressed L4 Light Failure Sensor 1, 2, 7–Ground : Approx. 12 volts with the stop light SW on 4, 8–Ground : Approx. 12 volts with the ignition SW at ON position 11–Ground : Always continuity [P] : Parts Location Code See Page See Page Code See Page 34 L4 36 R7 37 H17 36 R6 37 S6 35 [Q] : Relay Blocks Code 1 [R] See Page 18 Relay Blocks (Relay Block Location) R/B No.1 (Instrument Panel Brace LH) : Junction Block and Wire Harness Connector Code See Page Junction Block and Wire Harness (Connector Location) IB 20 Instrument Panel Wire and Instrument Panel J/B (Lower Finish Panel) 3C 22 Instrument Panel Wire and J/B No.3 (Instrument Panel Brace LH) [S] : Connector Joining Wire Harness and Wire Harness Code See Page Joining Wire Harness and Wire Harness (Connector Location) IE1 42 Floor Wire and Instrument Panel Wire (Left Kick Panel) BV1 50 Luggage Room Wire and Floor Wire (Luggage Room Left) [T] : Ground Points Code See Page Ground Points Location BL 50 Under the Left Center Pillar BO 50 Back Panel Center [U] : Splice Points Code I5 6 Code C7 See Page 44 Wire Harness with Splice Points Cowl Wire Code B18 See Page 50 Wire Harness with Splice Points Luggage Room Wire B [N] : Explains the system outline.

An outline of the engine control is explained here. 1. Input Signals (1) Water temp. signal circuit The water temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance varies according to the engine coolant temp. Thus the engine coolant temp. is input in the form of a control signal to TERMINAL THW of the engine ECU. (2) Intake air temp. signal circuit The intake air temp. sensor is detects the intake air temp. of air cleaner, which is input as a control signal to TERMINAL THA of the engine ECU. The intake air temp. sensor is detects the intake air temp. of inter cooler, which is input as a control signal to TERMINAL THIA of the engine ECU. (3) RPM signal circuit Camshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor. Camshaft position is input as a control signal to TERMINAL G+ of the engine ECU, and engine RPM is input into TERMINAL NE+. (4) Throttle signal circuit The accelerator position sensor detects the accelerator pedal opening angle, which is input as a control signal to TERMINALS VPA and VPA2 of the engine ECU. (5) Vehicle speed signal circuit The speed sensor detects the vehicle speed and inputs a control signal to TERMINAL SPD of the engine ECU via the combination meter. (6) Battery signal circuit Voltage is constantly applied to TERMINAL BATT of the engine ECU. When the ignition SW is turned to on, voltage for engine ECU operation is applied via the MAIN relay to TERMINAL +B of the engine ECU. (7) Started signal circuit To confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input as a control signal to TERMINAL STA of the engine ECU. (8) Fuel temp. signal circuit The fuel temp. sensor is detects the fuel temp., which is input as a control signal to TERMINAL THF of the engine ECU. (9) Intake air vacuum pressure signal system Intake air vacuum pressure is detected by the turbo pressure sensor and is input as a control signal to TERMINAL PIM of the engine ECU. 75 Engine Control 2. Control System ∗ EGR control The EGR control system detects the signals from each sensor, then the current is output to the TERMINAL EGR to control the VRV (EGR). ∗ Common rail pressure control The target rail pressure is calculated according to the engine status (Accelerator opening, engine speed) and environmental change detected by sensors. The fuel amount to be pressure–fed from the supply pump is calculated so as to match the indicated value of rail pressure sensor with the target value and the signal is sent to the intake amount adjusting valve of the supply pump in order to control the rail pressure. ∗ Fuel injection timing control The fuel injection timing is controlled by calculating the basic fuel injection timing based on the engine status (Accelerator opening, engine speed), making corrections according to environmental change detected by sensors, then sending a signal to the solenoid control valve of the injector via the injector driver (EDU). ∗ Fuel injection volume control The fuel injection volume is controlled by calculating the basic fuel injection volume based on the engine status (Accelerator opening, engine speed), making corrections according to environmental change detected by sensors and the inside pressure conditions in the rail, then sending a signal to the solenoid control valve of the injector via the injector driver (EDU). ∗ Pilot injection control The fuel injection volume and timing are controlled by calculating the pilot injection volume/timing based on the engine status (Accelerator opening, engine speed), making corrections according to environmental change detected by sensors, then sending a signal to the solenoid control valve of the injector via the injector driver (EDU). 3. Diagnosis System With the diagnosis system, when there is a malfunctioning in the engine ECU signal system, the malfunction system is recorded in the memory. The malfunctioning system can be found by reading the display (Code) of the check engine warning light. 4. Fail–Safe System When a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control based on the signals from that system, the fail–safe system either controls the system by using data (Standard values) recorded in the engine ECU memory or else stops the engine. 76 Service Hints E5 (A), E6 (B), E7 (C), E8 (D) Engine ECU BATT–E1 : Always

The electronically controlled transmission, however, electrically controls the line pressure, throttle pressure, lock–up pressure and accumulator pressure etc. through the solenoid valve. The electronically controlled transmission is a system which precisely controls gear shift timing and lock–up timing in response to the vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth driving possible by shift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing, squat and gear shift shock when starting off. 1. Lock–Up Operation When the transmission control ECU decides based on each signal that the lock–up condition has been met, the current flows through TERMINAL SL of the transmission control ECU to TERMINAL 7 of the ECT solenoid to GROUND, causing lock–up operation. 2. Stop Lamp SW Circuit If the brake pedal is depressed (Stop lamp SW on) when driving in lock–up condition, a signal is input to TERMINAL STP of the transmission control ECU. The transmission control ECU operates and cuts the current to the solenoid to release lock–up.

This results in improved directional stability and steerability during panic braking. 1. Input Signal (1) Speed sensor signal The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the skid control ECU with actuator. (2) Stop lamp SW signal A signal is input to TERMINAL STP of the skid control ECU with actuator when the brake pedal is depressed. 2. System Operation During sudden braking, the skid control ECU with actuator which has signals input from each sensor lets the hydraulic pressure acting on each wheel cylinder escape to the reservoir. The pump inside the skid control ECU with actuator is also operating at this time and it returns the brake fluid from the reservoir to the master cylinder, thus preventing locking of vehicle wheels. If the skid control ECU with actuator judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current acting on the solenoid is controlled and the hydraulic pressure is increased. Holding of the hydraulic pressure is also controlled by the ECU, by the same method as above, by repeated pressure reduction. Holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking.

D Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery. D Work must be started more than 90 seconds after the ignition SW is turned to the ”LOCK” position and the negative (–) terminal cable is disconnected from the battery. (The SRS is equipped with a back–up power source so that if work is started within 90 seconds from disconnecting the negative (–) terminal cable of the battery, the SRS may deploy.) D When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will be cleared. So before starting work, make a record of the contents in the audio memory system. When work is finished, reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, power telescopic steering, power seat and power outside rear view mirror which are all equipped with memory function. However, it is not possible to make a record of these memory contents. So when the work is finished, it will be necessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoid erasing the memory in each system, never use a back–up power supply from outside the vehicle. D Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair. D Do not expose the following parts directly to hot air or flame; D Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected; D Never use SRS parts from another vehicle. When replacing parts, replace with new parts. D For the purpose of reuse, never disassemble and repair the following parts. D If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector, replace with new one. D Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system. D Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice. D After work on the SRS is completed, check the SRS warning light. D If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair Manual. ∗ Steering wheel pad ∗ Center airbag sensor assembly ∗ Front airbag sensor assembly 121 SRS From Power Source System (See Page 60) 7. 5A MET 7. 5A IGN 1 2D 8 2B A5 Airbag Sensor (Front LH) D1 DLC3 B–O C8 Combination Meter IF1 2 IF1 IG2 BR–W B–W 21 TC 28 30 27 29 –SL +SL –SR A14 Airbag Sensor Assembly Center 2 W–B 1 1 2B 2 2B 18 2D 9 2D W–B Y 3 2B E2 26 W–B Y–B 5 2O E1 25 W–B 6 B–Y D– 5 W–B 21 2O D+ 14 B–Y B B J22(A), J23(B) Junction Connector B A Spiral Cable A15 Airbag Squib (Steering Wheel Pad) W–B ID 122 IF1 W–R 15 LA 1 BR B–Y 16 SIL 3 2 4 2B P–B Y 7 2B W 20 IF1 +SR 1 W–R 21 2Q –SR 2 BR 22 2Q 4 22 +SL 1 B–W –SL BR–W TC 13 B–O B–Y SRS SIL 7 P–B A/B 11 R–Y 21 A6 Airbag Sensor (Front RH) IE +SR System Outline The SRS is a driver protection device which has a supplemental role to the seat belts. When the ignition SW is turned to ON, the current from the ignition SW flows to TERMINAL 21 of the airbag sensor assembly center. If an accident occurs while driving, when the frontal impact exceeds a set level, the current from the ignition SW flows to TERMINAL 5 of the airbag sensor assembly center to the airbag squibs TERMINAL 6 of the airbag sensor assembly center to TERMINAL 25, 26 or BODY GROUND to GROUND, so that current flows to the airbag squibs and causes them to operate. The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver. : Parts Location Code See Page Code See Page Code See Page A5 36 A15 38 J22 A 38 A6 36 C8 38 J23 B 38 A14 38 D1 38 : Junction Block and Wire Harness Connector Code 2B 2D 2O 2Q See Page Junction Block and Wire Harness (Connector Location) 28 Instrument Panel Wire and Driver Side J/B (Instrument Panel Brace RH) 29 : Connector Joining Wire Harness and Wire Harness Code IF1 See Page 50 Joining Wire Harness and Wire Harness (Connector Location) Engine Room Main Wire and Instrument Panel Wire (Behind the Driver Side J/B) : Ground Points Code See Page Ground Points Location ID 48 Instrument Panel Reinforcement Center IE 48 Instrument Panel Reinforcement RH 123 124 2 GND 8 ID2 17 3 6 EA1 C C 16 15 (A/T, ∗1) 4WD GND 2 6 5 1 2 6 5 W–G A (A/T) 1 TFN L4 A B A B A B A A A A A A C J6 Junction Connector 7 (A/T) 13 2 1 2 G–W 1 EC N1 Neutral Start SW R–L (A/T) R–L G–B (A/T) 5 ID2 T5 Transfer Indicator SW (Neutral Position) 17 ID2 W–G DL2 G–B 12 (A/T) B–O (A/T) J 7(A), J 8(B) Junction Connector 4 12 ID2 (A/T) 31 W–B IG A/T P 21 W–B A3 ADD Actuator 4WD 1 2D (A/T) D W–G 6 R–B 2 T3 Transfer Indicator SW (4WD Position) F14 4WD Control ECU W–R B–Y 7. 5A MET W–B R–B C8 Combination Meter B (A/T, ∗1) ADD B 40A AM1 T4 Transfer Indicator SW (L4 Position) 5 EA1 J18 Junction Connector W–B EXI4 M W–B 3 DL1 (A/T) 12 ID1 W–B D W–G B–Y B–R IG1 1 J6 Junction Connector D DM2 (A/T) DM1 W–G DL2 1 R–W 10 (A/T) DL1 3 R–Y 1 G–W DM2 4 R B–Y 2 2A (∗1) DM1 8 Y A ADD R–B B T18 Transmission Control ECU EXI R–B (∗1) R–B I6 Ignition SW G–W Battery (∗1) R–B 100A ALT (∗1) G–W J6 Junction Connector B 4 AM1 (∗1) G–W S2 Skid Control ECU with Actuator W 4WD From Power Source System (See Page 60) ACC ∗ 1 : w/ ABS 10A GAUGE&ECU–IG 25 2S 2 ID1 W–G (A/T) 1 2G IND1 1 1F A W–B 2 1 1A System Outline Driving mode is switched to H2 or H4 or L4 when the driver operates the transfer shift lever. Transfer indicator SW (4WD position) is turned on when the transfer shift lever is shifted in 4WD (H4 or L4). 1. 2-4 Select System (1) Shifting from H4 to H2 When the transfer shift lever is changed from H4 to H2 position, transfer indicator SW (4WD position) detects OFF signal to activate the ADD motor, which results in changing the transfer to 2WD (H2 position). At this time, the transfer indicator SW (4WD position) are off. (2) Shifting from H2 to H4 When the transfer shift lever is changed from H2 to H4 position, transfer indicator SW (4WD position) detects ON signal to activate the ADD motor, which results in changing the transfer to 4WD (H4 position) to light up 4WD indicator. (3) Shifting from H4 to L4 When the transfer shift lever is changed from H4 to L4 position, the shift fork shaft moves to change the transfer to 4WD (L4 position), which results in turning ON transfer indicator SW (L4 position). ADD motor does not operate since it is only the lever operation. (4) Shifting from L4 to H4 When the transfer shift lever is changed from L4 to H4 position, the shift fork shaft moves. When transfer indicator SW (L4 position) is turned OFF, the transfer changes to 4WD (H4 position). ADD motor does not operate since it is only the lever operation. 2.

When the ignition SW is turned to ON position, the current from the ECU–IG&GAUGE fuse flows to TERMINAL 1 of the shift lock control ECU. 1. Shift Lock Mechanism If the brake pedal is depressed with the ignition SW set at ON (The stop lamp SW is on), the shift lock control ECU is activated, allowing the driver to change the shift lever to a position other than the P position. 2. Key Interlock Mechanism With the ignition SW at ON or ACC position, when the shift lever is put in P position, the current flowing from TERMINAL 12 of the shift lock control ECU to key interlock solenoid is cut off. This causes the key interlock solenoid to turn off (Lock lever disengages from LOCK position) and the ignition key can be turned from ACC to LOCK position.

Manual Down or Up Operation When the power window master SW is pushed one step, the motor rotates to open the window. When the power window master SW is pulled up one step, the motor rotates in the opposite direction, to close the window. All the other windows can be opened/closed as well, by the operation of the power window master SW or respective power window SW. When the window lock SW is pushed to the lock side, the ground circuit to the passenger’s window becomes open. As a result, even if Open/Close operation of the passenger’s window is attempted, the current from TERMINAL E of the power window master SW is not grounded and the motor does not rotate, so the passenger’s window can not be operated and window lock occurs. 2. Auto Down Operation (Driver’s Window) When the power window master SW is pushed two steps, the motor rotates to open the window automatically. 3. Stopping of Auto Down Operation (Driver’s Window) Auto operation can be stopped in mid–course with switching power window master SW one step upward during the down operation.

Low Speed Position With the front wiper SW turned to LO position, the current flows from TERMINAL (B) 3 of the front wiper and washer SW to TERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor to TERMINAL 4 to GROUND and causes the windshield wiper motor to run at low speed. 2. High Speed Position With the front wiper SW turned to HI position, the current flows from TERMINAL (B) 3 of the front wiper and washer SW to TERMINAL (B) 1 to TERMINAL 3 of the windshield wiper motor to TERMINAL 4 to GROUND and causes the windshield wiper motor to run at high speed. 3. INT Position With the front wiper SW turned to INT position, the wiper relay operates and current flows from TERMINAL (B) 3 of the front wiper and washer SW to TERMINAL (A) 2 to GROUND. This activates the intermittent circuit and the current flows from TERMINAL (B) 3 of the front wiper and washer SW to TERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor to TERMINAL 4 to GROUND and the wiper operates. The intermittent operation is controlled by the charge/discharge function of the condenser installed in the relay, and the intermittent time is controlled by a time control SW to change the charging time of the condenser (w/ INT time SW). Intermittent operation is controlled by a condenser charge and discharge function in the relay (w/o INT time SW). 4. Mist Position With the front wiper SW turned to MIST position, the current flows from TERMINAL (B) 3 of the front wiper and washer SW to TERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor to TERMINAL 4 to GROUND and causes the windshield wiper motor to run at low speed. 5. Washer Interlocking Operation With the washer SW pulled to ON position, the current flows from the WIP fuse to TERMINAL 1 of the windshield washer motor to TERMINAL 2 to TERMINAL (A) 1 of the front wiper and washer SW to TERMINAL (A) 2 to GROUND and causes the windshield washer motor to run and the window washer to spray. Simultaneously, current flows from the WIP fuse to TERMINAL (B) 3 of the front wiper and washer SW to TERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor to TERMINAL 4 to GROUND, causing the wiper to function.

HTR relay. When the ignition SW is turned on, the current flows through the ECU–IG&GAUGE fuse to TERMINAL 1 of the HTR relay to TERMINAL 2 to TERMINAL 6 of the blower SW. Blower Motor Operation ∗ Low speed operation When the blower SW is moved to LO position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to GROUND, causing the HTR relay to turn on. This causes the current flows from the FR HTR fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower resistor to TERMINAL 1 to GROUND, rotating the blower motor at low speed. ∗ Medium speed operation (Operation at M1, M2) When the blower SW is moved to M1 position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to GROUND, causing the HTR relay to turn on. This causes the current flows from the FR HTR fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower resistor to TERMINAL 3 to TERMINAL 2 of the blower SW to TERMINAL 5 to GROUND. At this time, the blower resistance of the blower resistor is smaller than at low speed, so the blower motor rotates at medium low speed. When the blower SW is moved to M2 position, the current flows through the HTR relay to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower resistor to TERMINAL 2 to TERMINAL 1 of the blower SW to TERMINAL 5 to GROUND. At this time, resistance of the blower resistor is smaller than at M1 position, so the blower motor rotates at medium high speed. ∗ High speed operation When the blower SW is moved to HI position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to GROUND, causing the HTR relay to turn on. This causes the current flows from the FR HTR fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower SW to TERMINAL 5 to GROUND, rotating the blower motor at high speed.

Wire colors are indicated by an alphabetical code. B = Black W = White BR = Brown L = Blue V SB = Sky Blue = Violet R = Red G = Green LG = Light Green P Y GR = Gray = Pink = Yellow [F] : Junction Block (The number in the circle is the J/B No. and the connector code is shown beside it). Junction Blocks are shaded to clearly separate them from other parts. Example: 3C indicates that it is inside Junction Block No.3 O = Orange The first letter indicates the basic wire color and the second letter indicates the color of the stripe. Example: L–Y [G] : Indicates related system. L (Blue) [H] : Indicates the wiring harness and wiring harness connector. The wiring harness with male terminal is shown with arrows ( ). Outside numerals are pin numbers. Y (Yellow) [C] : The position of the parts is the same as shown in the wiring diagram and wire routing. [D] : Indicates the pin number of the connector. The numbering system is different for female and male connectors. Example : Numbered in order from upper left to lower right Numbered in order from upper right to lower left Female [I] Male ( ) : ( ) is used to indicate different wiring and connector, etc. when the vehicle model, engine type, or specification is different. [J] : Indicates a shielded cable. Female Male The numbering system for the overall wiring diagram is the same as above [E] : Indicates a Relay Block. No shading is used and only the Relay Block No. is shown to distinguish it from the J/B. Example : [K] : Indicates and located on ground point. [L] : The same code occuring on the next page indicates that the wire harness is continuous.
