HOW TO USE THIS MANUAL B This manual provides information on the electrical circuits installed on vehicles by dividing them into a circuit for each system. 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.

B HOW TO USE THIS MANUAL [O]

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.

WIRE COLOR AND TERMINAL NUMBER In some parts of the instrumental panel wiring harness, the same wire color (i.e. SB: Sky Blue) is used for all the wiring to a specific connector. In order to identify the wiring, the terminal number is printed on the wiring. Install the wiring to the connector position with the same terminal number. Some early production Vehicles may not have these terminal numbers printed.

ENGINE CONTROL AND ENGINE IMMOBILISER SYSTEM SYSTEM OUTLINE The engine control system utilizes a microcomputer and maintains overall control of the engine, transmission etc. An outline of the engine control is given here. 1. INPUT SIGNALS (1) Engine coolant temp. signal circuit The engine coolant temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance which varies according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the engine control module as a control signal. (2) Intake air temp. signal circuit The intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as a control signal to TERMINAL THA of the engine control module. (3) Oxygen sensor signal circuit The oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensors to TERMINALS OXL1, OXR1, OXL2, OXR2 of the engine control module. (4) RPM signal circuit The camshaft position is detected by the camshaft position sensor and is input into TERMINAL G2 of the engine control module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal is input into TERMINAL NE+ of the engine control module. (5) Throttle position sensor signal circuit The throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINAL VTA of the engine control module. (6) Vehicle speed circuit The vehicle speed sensor (Combination meter) detects the vehicle speed, and the signal is input into TERMINAL SPD of the engine control module via the combination meter. (7) Battery signal circuit Voltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, the voltage for engine control module start up power supply is applied through the EFI or ECD relay, to TERMINALS +B, +B1 of the engine control module. The current from the IGN fuse flows to TERMINAL IGSW of the engine control module, and voltage is constantly applied to TERMINAL +BM. (8) Intake air volume signal circuit The intake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of the engine control module. (9) Stop light SW signal circuit The stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP of the engine control module as a control signal. (10) Starter signal circuit To confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking is detected, and is input into TERMINAL STA of the engine control module as a control signal. (11) Engine knock signal circuit Engine knocking is detected by the knock sensors, and is input into TERMINALS KNKL, KNKR of the engine control module as a control signal.

2. CONTROL SYSTEM ∗ SFI system The SFI system monitors the engine condition through the signals input from each sensors to the engine control module. The control signal is sent to the engine control module TERMINALS #1, #2, #3, #4, #5, #6, #7, #8 to operate the injector (Fuel injection). The SFI system controls the fuel injection by the engine control module in response to the driving conditions. ∗ ESA system The ESA system monitors the engine condition through the signals input from each sensors to the engine control module. The best ignition timing is decided according to this data and the data memorized in the engine control module. The control signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5, IGT6, IGT7, IGT8, and these signals control the igniter to provide the best ignition timing. ∗ Heated oxygen sensor heater control system The heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaust emission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine control module evaluates the signals from each sensors, and outputs current to TERMINALS HTL, HTR, HTL2, HTR2 to control the heater. ∗ Fuel pump control system The engine control module supplies current to TERMINAL FPC, and controls the operation speed of the fuel pump with the fuel pump control ECU. ∗ ACIS The ACIS includes a valve in the bulkhead separating the surge tank into two parts. This valve is opened and closed in accordance with the driving conditions to control the intake manifold length in two stages, for increased engine output in all ranges from low to high speeds. ∗ ETCS–i The ETCS–i controls the engine output at its optimal level in accordance with the opening of the accelerator pedal, under all driving conditions. 3. DIAGNOSIS SYSTEM When there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in the memory. The malfunctioning system can be found by reading the code displayed on the malfunction indicator lamp. 4. FAIL–SAFE SYSTEM When a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued control based on that system. In that case, the fail–safe system either controls the system using the data (Standard values) recorded in the engine control module memory, or else stops the engine.

SYSTEM OUTLINE 1. DAYTIME RUNNING LIGHT OPERATION When the engine is started, a signal from the generator is input to daytime running light relay (Main) TERMINAL 11. At this time, if the parking brake lever is pulled up, the relay does not operate, so the daytime running light system does not operate. When the parking brake lever is released, a signal is input to daytime running light relay (Main) TERMINAL 8. This activates the daytime running light relay (Main), and turns on the DIMMER relay. The current from the battery flows through the fusible link block to DIMMER relay (Point side) to HEAD (LH–UPR) fuse to headlight LH (High) to headlight RH (High) to daytime running light relay No.3 TERMINAL (A) 5 to TERMINAL (A) 3 to GROUND, and the headlights are lit dimmer than usual. Once the daytime running light system is operated, the headlights remain lit even though the parking brake lever is pulled up. The headlights remain lit even when the engine stops with the ignition SW on, and the signal from the generator is cut off. When the ignition SW is turned from on to off, the daytime running light system is canceled and the headlights are turned off. If the engine is started with the parking brake lever released, the daytime running light system operates and the headlights are turned on when the engine starts running. 2. HEADLIGHT OPERATION ∗ When the light control SW is turned to HEAD position When the light control SW is turned to HEAD position, the HEAD relay is turned on. At the same time, a signal is input to the daytime running light relay (Main) TERMINAL 5. As a result, the daytime running light relay (Main) cancels the daytime running light system operation, and turns off the headlight LH, RH (High). Simultaneously, the current from the battery flows from the fusible link block to HEAD relay (Point side) to HEAD (LH–LWR), HEAD (RH–LWR) fuse to headlight LH, RH (Low) to GROUND, and from the HEAD (LH–LWR) fuse to combination meter TERMINAL 6 to TERMINAL 2 to GROUND, and turns on both the low beam of the headlight and HEAD indicator light (USA). ∗ When the dimmer SW is turned to HIGH position When the light control SW is turned to HEAD position, the low beam of the headlights are turned on, and at the same time, current flows from HEAD (RH–LWR) fuse to daytime running light relay No.3 (Coil side) to GROUND, and turns on the daytime running light relay No.3. When the dimmer SW is turned to HIGH position, a signal is input to daytime running light relay (Main) TERMINAL 16. This activates the DIMMER relay, and the current from the battery flows from the fusible link block to DIMMER relay (Point side) to HEAD (LH–UPR) fuse to headlight LH (High) to daytime running light relay No.3 TERMINAL (B) 1 to TERMINAL (B) 2 to GROUND. At the same time the current flows from DIMMER relay (Point side) to HEAD (RH–UPR) fuse to daytime running light relay No.3 TERMINAL (A) 2 to TERMINAL (A) 5 to headlight RH (High) to daytime running light relay No.3 TERMINAL (B) 2 to TERMINAL (B) 1 to GROUND. Also current flows from the daytime running light relay No.3 TERMINAL (A) 3 to TERMINAL (A) 5 to combination meter TERMINAL 4 to TERMINAL 2 to GROUND. As a result the headlight high beam, low beam, and high beam indicator light are turned on simultaneously. ∗ When the dimmer SW is turned to FLASH position When the dimmer SW is turned to FLASH position, the HEAD relay is turned on, the daytime running light system is canceled and the daytime running light relay No.3 is turned on, as when the light control SW is turned to HEAD position. At the same time, the DIMMER relay is turned on as when the dimmer SW is turned to HIGH position. As a result, the headlight high beam, low beam, and high beam indicator light are turned on simultaneously. SERVICE HINTS HEAD RELAY 1–2 : Closed with light control SW at HEAD position or dimmer SW at FLASH position (When the light auto turn off system does not operate) DIMMER RELAY 1–2 : Closed with daytime running light operation : Closed with light control SW at HEAD position and dimmer SW at HIGH position : Closed with dimmer SW at FLASH position C18 COMBINATION SW 13–16 : Closed with light control SW at HEAD position 8–16 : Closed with dimmer SW at FLASH position 7–16 : Closed with dimmer SW at HIGH or FLASH position

LIGHT AUTO TURN OFF OPERATION ∗ When headlights are on When the ignition SW turned from on to off with the headlights on (Light control SW at HEAD position), a signal is input to instrument ECU TERMINAL SIG. When the driver door is opened at this time, a signal is input from the door courtesy SW front LH to the instrument ECU TERMINAL DCY. The instrument ECU TERMINAL HRY is controlled to turn off the HEAD relay. As a result, the current to the headlight is cut off and the light is turned off. ∗ When taillights are on When the ignition SW turned from on to off with the taillights on (Light control SW at TAIL position), a signal is input to instrument ECU TERMINAL SIG. When the driver door is opened at this time, a signal is input from the door courtesy SW front LH to the instrument ECU TERMINAL DCY. The instrument ECU TERMINAL TRY is controlled to turn off the TAIL relay. As a result, the current to the taillight is cut off and the light is turned off.

SYSTEM OUTLINE When the ignition SW turned on, the current from the WIPER fuse flows to the front wiper and washer SW TERMINAL 17, and front wiper motor TERMINAL 2. 1. LOW POSITION When the wiper SW is turned to LO position, the current flows from the front wiper and washer SW TERMINAL 17 to TERMINAL 7 to front wiper motor TERMINAL 1 to TERMINAL 5 to GROUND, and operates the front wiper motor at low speed. 2. HIGH POSITION When the wiper SW is turned to HI position, the current flows from the front wiper and washer SW TERMINAL 17 to TERMINAL 8 to front wiper motor TERMINAL 4 to TERMINAL 5 to GROUND, and operates the front wiper motor at high speed. 3. INT POSITION When the wiper SW is turned to INT position, the relay operates and the current which is connected by the relay function flows from the front wiper and washer SW TERMINAL 17 to TERMINAL 2 to GROUND, and operates the wipe. 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. 4. WASHER CONTINUOUS OPERATION When the washer SW is turned on, the current flows from the washer motor TERMINAL 2 to TERMINAL 5 to front wiper and washer SW TERMINAL 11 to TERMINAL 2 to GROUND, operates the washer motor and the window washer emits a water spray. This causes the current to flow to the washer continuous operation circuit in front wiper and washer SW TERMINAL 11 to TERMINAL 7 to front wiper motor TERMINAL 1 to TERMINAL 5 to GROUND, and operates the wiper. SERVICE HINTS C21 FRONT WIPER AND WASHER SW [COMB.

SYSTEM OUTLINE When the ignition SW is turned on, the current flows from WIPER fuse to washer motor TERMINAL 2, rear wiper relay TERMINAL 3 and TERMINAL 4 , and rear wiper motor TERMINAL 1 respectively. 1. REAR WIPER NORMAL OPERATION When the ignition SW is turned on, and the rear wiper and washer SW is turned to ON position, the current flows from rear wiper relay (Coil side) to instrument ECU TERMINAL (C) 3 to TERMINAL (A) 17 to rear wiper and washer SW TERMINAL 10 to TERMINAL 2 to GROUND, and turns on the rear wiper relay. As a result, the current flows from rear wiper relay TERMINAL 3 to TERMINAL 2 to rear wiper motor TERMINAL 3 to TERMINAL 2 to GROUND, and operates the rear wiper. 2. REAR WIPER INTERMITTENT OPERATION When the ignition SW is turned on, and the rear wiper and washer SW is turned to INT position, the current flows from rear wiper relay (Coil side) to instrument ECU TERMINAL (C) 3 to TERMINAL (A) 16 to rear wiper and washer SW TERMINAL 13 to TERMINAL 2 to GROUND, and the intermittent circuit in the instrument ECU is controlled to operate the wiper intermittently. 3. WASHER OPERATION When the ignition SW is turned on, and the rear wiper and washer SW is turned from OFF to WASH position, the current flows from the WIPER fuse to washer motor TERMINAL 2 to TERMINAL 3 to rear wiper and washer SW TERMINAL 12 to TERMINAL 2 to GROUND. This activates the washer motor, and the window washer emits a water spray. When the rear wiper and washer SW is turned to ON position, the window washer emits a water spray during rear wiper normal operation.

ELECTRONICALLY CONTROLLED TRANSMISSION AND A/T INDICATOR SYSTEM OUTLINE The electronically controlled transmission electrically controls the, throttle pressure, lock–up pressure, and accumulator pressure etc. through the solenoid valve. The electronically controlled transmission is a system which precisely controls the 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 of the 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. GEAR SHIFT OPERATION When driving, the engine warm up condition is input as a control signal from the engine coolant temp. sensor to TERMINAL THW of the engine control module, and the vehicle speed is input to TERMINAL SP2+ of the engine control module from the vehicle speed sensor. At the same time, the throttle valve opening signal from the throttle position sensor is input to TERMINALS VTA, VTA2 of the engine control module as a throttle angle signal. Based on these signals, the engine control module selects the best shift position for the driving conditions and sends current to the electronically controlled transmission solenoid. 2. LOCK–UP OPERATION When the engine control module decides based on each signal that the lock–up condition has been met, the current flows from the engine control module TERMINAL SL to TERMINAL 7 of the electronically controlled transmission solenoid to GROUND. 3. STOP LIGHT SW CIRCUIT If the brake pedal is depressed (Stop light SW on) when driving in lock–up position, a signal is input to TERMINAL STP of the engine control module. As a result, the engine control module cuts the current to the solenoid to release the lock–up. 4. ELECTRONICALLY CONTROLLED TRANSMISSION PATTERN SELECT SW CIRCUIT When the electronically controlled transmission pattern select SW is switched to PWR, a signal is input to TERMINAL PWR of the engine control module, and the engine control module controls to enable shift–up and shift–down at a higher speed range than usual. In that case, the ECT PWR indicator light in the combination meter is lit up. When the electronically controlled transmission pattern select SW is switched to 2nd position, a signal is input to the engine control module TERMINAL SNWI, and through control of the engine control module, the gear shift of the transmission is made from 2nd position. The 2nd STRT indicator light in the combination meter is lit up. 5. OVERDRIVE CIRCUIT ∗ O/D main SW on When the O/D main SW is turned on (SW point is open), a signal is input to TERMINAL ODMS of the engine control module and engine control module operation causes gear shift when the conditions for overdrive are met. ∗ O/D main SW off When the O/D main SW is turned off (SW point is closed), a signal is input into TERMINAL ODMS of the engine control module, and turns on the O/D off indicator light. This activates the ECU, and the transmission system is controlled not to shift to overdrive. 6. TRANSFER SHIFT OPERATION When the transfer shift lever is moved to L position, a signal is input into TERMINAL L4 of the engine control module. In addition when the transfer shift lever is moved to N position a signal is input to engine control module TERMINAL TFN. The engine control module detects the transfer condition through this.

SYSTEM OUTLINE The cruise control system is a constant vehicle speed controller which controls the opening angle of the engine throttle valve by the SW, and allows driving at a constant speed without depressing the accelerator pedal. SET OPERATION When the CRUISE SW is turned on, the systems starts preparations for cruise control and turns on the indicator light in the combination meter. SET SPEED CONTROL When the SET/COAST SW is operated with the CRUISE SW turned on during driving, the speed is controlled at a constant speed. COAST CONTROL When the SET/COAST SW is kept turned on during cruise control driving, the engine control module controls the throttle valve to decelerate the vehicle speed. Every time the SET/COAST SW is turned on instantaneously, the vehicle speed is decelerated approx. 1.5 km/h. ACCEL CONTROL When the RES/ACC SW is kept turned on during cruise control driving, the engine control module controls the throttle valve to accelerate the vehicle speed. Every time the SET/COAST SW is turned on instantaneously, the vehicle speed is accelerated approx. 1.5 km/h. RESUME CONTROL If the vehicle speed is within the low speed limit (Approx. 40 km/h, 25 mph) when canceling the cruise control, operation of the RES/ACC SW accelerates the vehicle speed and resumes the level before canceling the cruise control. MANUAL CANCEL MECHANISM If any of the following signals are input during cruise control driving, the cruise control is canceled. ∗ The stop light SW is on ∗ The CANCEL SW is turned on ∗ The CRUISE SW is turned off AUTO CANCEL FUNCTION If any of the following conditions are detected, the cruise control is canceled: ∗ Failure in the stop light SW wiring ∗ Abnormality in the vehicle speed signal ∗ Malfunction in the electronically controlled throttle parts OVERDRIVE FUNCTION The overdrive may be canceled if the vehicle travels on a upward slope during cruise control driving. After the overdrive is canceled, if the vehicle speed exceeds the overdrive return speed (Set speed ( 2 km/h, 1.2 mph) ) and it is determined that the slope has finished, and the vehicle returns to overdrive mode again.

ACTIVE HEIGHT CONTROL SUSPENSION AND SYSTEM OUTLINE This system is a combined system of the vehicle height adjustment system and the damping force control system. 1. INPUT SIGNALS (1) Height control sensor signal The vehicle height and the distance between the tire and body frame is detected, and is input to suspension control ECU TERMINAL SHFL, SHFR, SHRR. (2) Fluid pressure sensor signal The hydraulic pressure is detected, and the signal is input to suspension control ECU TERMINAL PACC. (3) Temperature sensor signal The fluid temperature is detected, and the signal is input to suspension control ECU TERMINAL TOIL. (4) Height control SW signal Detects the changes in the target vehicle height, and the signal is input to suspension control ECU TERMINAL DNSW, UPSW. Detects the changes in the vehicle height control, and the signal is input to suspension control ECU TERMINAL NSW. (5) Differential lock detection SW signal Detects the differential lock, and the signal is input to suspension control ECU TERMINAL EXI. (6) L detection SW signal Detects the transfer gear L, and the signal is input to suspension control ECU TERMINAL L4SW. (7) Stop light SW signal Detects the brake signal, and the signal is input to suspension control ECU TERMINAL STP. (8) Generator signal Detects whether the engine is running or not, and the signal is input to suspension control ECU TERMINAL REG. (9) Door courtesy SW signal Detects whether the door is open or closed, and the signal is input to suspension control ECU TERMINAL DOOR. (10) Steering sensor signal Detects the rotation number of the steering wheel, and the signal is input to suspension control ECU TERMINAL SS1, SS2. (11) Wheel speed sensor signal Detects the wheel speed signal, and the signal is input to suspension control ECU TERMINAL FLO, FRO. (12) Damping mode select SW signal Detects whether the damping force mode is selected or not, and the signal is input to suspension control ECU TERMINALS TSW1, TSW2. (13) Intelligent tester communication signal The intelligent tester requirement signal is sent to suspension control ECU TERMINAL SIL. The suspension control ECU also sends back a signal to the intelligent tester. 2. VEHICLE HEIGHT ADJUSTMENT FUNCTION (1) Vehicle height adjustment by the SW By operating the SW, the vehicle height can be adjusted to three heights, low, normal, and high. (2) Automatic leveling function The vehicle height is maintained at a certain level when the load is within the specified load capacity. (3) Vehicle speed detection function The height is adjusted automatically in response to the vehicle speed. (4) Extra HI mode In L range with the height at HI mode, the height is raised 20 mm automatically, when the wheels are idling on a bumpy road surface. (5) Vehicle height control SW When the vehicle height control SW is turned off, the vehicle height control functions could be inhibited.

183

ADAPTIVE VARIABLE SUSPENSION 3. DAMPING FORCE CONTROL FUNCTION (1) Bouncing control The front and rear wheels are independently controlled electronically, to ensure adequate damping force at all times, in response to the bumpy road surface. (2) Harshness control The damping force is controlled not to increase when the road condition does not require damping force, to ensure smooth and comfortable riding. (3) Unsprung vibration control When unsprung sympathetic vibration is detected, the damping force is controlled so that it does not decrease below a certain level, to prevent such vibration and converge it, to ensure road holding. (4) Vehicle speed sensing control To ensure optimal balance of comfortable riding and road holding, the minimum damping force is increased as the vehicle speed increases. (5) Anti–roll control When the driver makes a turn, the damping force is controlled electronically according to the condition, and slows down the vehicle rolling speed. (6) Anti–dive control The vehicle dive condition is detected at an early stage through braking and the vehicle wheel speed signal, and the damping force is controlled according to the condition, to slow down the dive speed when decelerating. (7) Anti–squat control The vehicle squat condition at acceleration is detected at an early stage, and the damping force is switched to a higher level to avoid squat. (8) Damping mode select SW The damping mode select SW has 4 modes, and can be changed according to the driver preference. 4. WHEEL DISCONNECTION FUNCTION Usually the right and left wheels are connected, but when the driver turns the steering wheel, the wheels are disconnected in response to the condition. This is to prevent roll angle increase when making a turn.

SYSTEM OUTLINE 1. ABS OPERATION If the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of the wheel cylinders for all the four wheels to automatically avoid wheel locking and ensure the directional and steering stability of the vehicle. If the brake pedal is depressed suddenly, the ABS & BA & TRAC & VSC ECU controls the solenoids in the actuators using the signals from the sensors to move the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If the ABS & TRAC & VSC ECU detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls the solenoids in the actuators to increase the braking pressure. 2. TRACTION CONTROL OPERATION The traction control system controls the engine torque, the hydraulic pressure of the driving wheel cylinders, slipping of the wheels which may occur at start or acceleration of the vehicle, to ensure an optimal driving power and vehicle stability corresponding to the road conditions. 3. VSC OPERATION Unexpected road conditions, vehicle speed, emergency situation, and any other external factors may cause large under– or over–steering of the vehicle. If this occurs, the VSC system automatically controls the engine power and wheel brakes to reduce the under– or over–steering. To reduce large over–steering : If the VSC system determines that the over–steering is large, it activates the brakes for the outer turning wheels depending on the degree of the over–steering to produce the moment toward the outside of the vehicle and reduce the over–steering. To reduce large under–steering : If the VSC system determines that the under–steering is large, it controls the engine power and activates the rear wheel brakes to reduce the under–steering. VSC indicator light If an error occurs in the VSC system, the VSC indicator lights up to warn the driver. 4. TRACTION MODE AND VSC FUNCTION When the center differential of the transfer is locked, the VSC function is turned off. At this time, the VSC OFF indicator light in the combination meter will come on, and informs the driver that the VSC function is OFF. 5. MUTUAL SYSTEM CONTROL To efficiently operate the VSC system at its optimal level, the VSC system and other control systems are mutually controlled while the VSC system is being operated. Engine throttle control The engine power does not interfere with the VSC brake control by controlling the opening of the throttle and reducing the engine output. Engine control and electronically controlled transmission control The strong braking force does not interfere with the braking force control of the VSC system by turning off the accel. and reducing changes in the driving torque at shift–down. VSC system operation indication The slip indicator light flashes and the buzzer sounds intermittently to warn the driver that the current road is slippery, while the VSC system is being operated. 6. FAIL SAFE FUNCTION If an error occurs in the ABS & BA & TRAC & VSC ECU, sensor signals, and/or actuators, the ABS & BA & TRAC & VSC ECU inhibits the brake actuator control and inputs the error signal to the engine control module. According to the error signal, the brake actuator turns off the solenoid and the engine control module rejects any electronically controlled throttle open request from the VSC system. As a result, the vehicle functions without the ABS, BA, TRAC, and VSC systems.

SRS NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionary instructions and the procedure and precautions in the Repair Manual for the applicable model year. 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. Work must be started after 90 seconds from when the ignition switch 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 be deployed.) When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will be canceled. So before starting work, make a record of the contents memorized in the audio memory system. When work is finished, reset the audio systems as they were before and adjust the clock. This vehicle has power tilt and 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 the memory contents. So when the work is finished, it will be necessary to explain this fact tot the customer, and ask the customer to adjust the features and reset the memory. To avoid erasing the memory in each memory system, never use a back–up power supply from outside the vehicle. Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs. Do not expose the steering wheel pad, front passenger airbag assembly, seat belt pretensioner and center airbag sensor assembly directly to hot air or flames. Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbag assembly, seat belt pretensioner and center airbag sensor assembly should be inspected. Never use SRS parts from another vehicle. When replacing parts, replace them with new parts. Never disassemble and repair the steering wheel pad, front passenger airbag assembly, seat belt pretensioner and center airbag sensor assembly in order to reuse it. If the steering wheel pad, front passenger airbag assembly, seat belt pretensioner and center airbag sensor assembly has been dropped, or if there are cracks, dents or other defects in the case, bracket or connector, replace them with new ones. Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system’s electrical circuits. Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices. After work on the SRS is completed, perform the SRS warning light check. If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair Manual.

C6 CENTER AIRBAG SENSOR ASSEMBLY

SRS SYSTEM OUTLINE The SRS is a driver and front passenger protection device which has a supplemental role to the seat belts. When the ignition SW is turned on, the current from the SRS fuse flows to the center airbag sensor assembly TERMINAL 6. Only when the ignition SW is on does the current from the IGN fuse flow to center airbag sensor assembly TERMINAL 5. In case an accident occurs while driving, when the frontal impact exceeds a predetermined level, the current from the SRS or IGN fuse flows to center airbag sensor assembly TERMINALS 14, 10, 16, 8 to airbag squibs and pretensioners to center airbag sensor assembly TERMINALS 13, 11, 17, 7 to TERMINALS 27, 28 or BODY GROUND to GROUND. The current flows to the airbag squibs and pretensioners, and operates the airbag. The airbag stored in the steering wheel pad is instantaneously expanded to soften the shock to the driver. The airbag stored in the front passenger’s instrument panel is instantaneously expanded to soften the shock to the front passenger. The pretensioners ensure the seat belt restrainability. : PARTS LOCATION Code

SYSTEM OUTLINE 1. MANUAL DOWN OR UP OPERATION When the power window master SW is pressed one step, the current flows from the power window master SW TERMINAL D to power window motor front LH to power window master SW TERMINAL U to GROUND, and rotates the motor to open the window. When the power window master SW is pulled one step, the current flows from the power window master SW TERMINAL U to power window motor front LH to power window master SW TERMINAL D to GROUND, and rotates the motor to close the window. For the other windows, as the power window master SW and power window SW is operated, the relevant door window is opened or closed. 2. AUTO DOWN OR UP OPERATION When the power window master SW is pushed two steps, the power window master SW determines it is in auto mode and the current flows from the power window master SW TERMINAL D to power window motor front LH to power window master SW TERMINAL U to GROUND, and rotates the motor to open the window automatically. When the power window master SW is pulled two steps, the power window master SW determines it is in auto mode and the current flows from the power window master SW TERMINAL U to power window motor front LH to power window master SW TERMINAL D to GROUND, and rotates the motor to close the window automatically. Accordingly, when each window switch of the power window control SW is operated, the relevant door window is automatically opened/closed. 3. CATCHING PREVENTION FUNCTION When any foreign matter is caught in the window during power window up operation, the pulse sensor in the power window motor detects the changes in the number of motor rotations and forcibly opens the door window 50 mm, or when the window opening is less than 200 mm, it opens the window until the opening is 200 mm. 4. KEY OFF POWER WINDOW OPERATION It is possible to operate the power window for approx. 43 seconds after the ignition SW is turned from on to off. However, when the door is opened while the window is being operated, the power window operation is stopped even though 43 seconds have not elapsed.

MOON ROOF SYSTEM OUTLINE In this system, the HALL IC in the moon roof control ECU detects the changes in motor rotation, and allows opening/closing, tilting up/down of the moon roof by one touch operation. In addition, catching prevention function during moon roof operation is also provided. Voltage is constantly applied from POWER fuse to moon roof control ECU TERMINAL 5 and POWER RELAY TERMINAL 5. 1. SLIDE OPEN OPERATION When the moon roof control SW is kept pressed to OPEN position for approx. 0.3 seconds or longer (Limit SW No.1 off, limit SW No.2 on), a signal is input from moon roof control SW TERMINAL 5 to moon roof control ECU TERMINAL 9. This activates the moon roof control ECU and rotates the motor to open the moon roof automatically. Then, when the limit SW No.1 is turned on and then turned off again, the pulse signal sent from the HALL IC activates the moon roof control ECU, and determines that the moon roof is fully open, and stops the motor. If other operation SW or the open SW is operated while the moon roof is being opened, the moon roof control ECU is activated to stop the moon roof operation. In addition, when the moon roof is tilted up, the slide open operation does not function. 2. SLIDE CLOSE OPERATION When the moon roof control SW is kept pressed to CLOSE position for approx. 0.3 seconds or longer (Limit SW No.1 off, limit SW No.2 off), a signal is input from moon roof control SW TERMINAL 4 to moon roof control ECU TERMINAL 10. This activates the moon roof control ECU and rotates the motor to close the moon roof automatically. Then, when the limit SW No.2 is turned on, the pulse signal sent from the HALL IC activates the moon roof control ECU, and determines that the moon roof is closed fully, and stops the motor. If other operation SW or the close SW is operated while the moon roof is being closed, the moon roof control ECU is activated to stop the moon roof operation. 3. TILT UP OPERATION When the moon roof control SW is kept pressed to UP position for approx. 0.3 seconds or longer (Limit SW No.1 off, limit SW No.2 on), a signal is input from moon roof control SW TERMINAL 1 to moon roof control ECU TERMINAL 4. This activates the moon roof control ECU and rotates the motor to tilt up the moon roof automatically. If the pulse signal is not input from the HALL IC for 0.5 seconds or longer, it determines that the moon roof is fully tilted up, and stops the motor. If other operation SW or the tilt up SW is operated while the moon roof is being tilted up, the moon roof control ECU is activated to stop the moon roof operation. In addition, when the moon roof is opened, the tilt up operation does not function. 4. TILT DOWN OPERATION When the moon roof control SW is kept pressed to DOWN position for approx. 0.3 seconds or longer (Limit SW No.1 on, limit SW No.2 on), a signal is input from moon roof control SW TERMINAL 2 to moon roof control ECU TERMINAL 3. This activates the moon roof control ECU and rotates the motor to tilt down the moon roof automatically. Then, when the limit SW No.1 is turned off, the pulse signal sent from the HALL IC activated the moon roof control ECU, and determines that the moon roof is closed fully, and stops the motor. If other operation SW or the tilt down SW is operated while the moon roof is being tilted down, the moon roof control ECU is activated to stop the moon roof operation. 5. CATCHING PREVENTION FUNCTION During slide close or tilt down operation, if the moon roof control ECU detects a catching load from the changes in the rotation of the motor, the operation is stopped, and the motor is rotated in the reverse direction. ∗ Slide close operation The moon roof is moved approx. 200 mm in the reverse direction (Slide open) after a catching load has been detected. However, if the full open position is detected before moving approx. 200 mm, the reverse movement is stopped. ∗ Tilt down operation If a catching load is detected, the moon roof is moved in the reverse direction until fully tilted up. 6. KEY OFF MOON ROOF OPERATION Within approx. 45 seconds after the ignition SW is turned from on to off, the moon roof can be operated. However, if the driver or front passenger door is opened during this period of time, the moon roof operation is stopped even though 45 seconds have not elapsed. 7. FAIL–SAFE FUNCTION If the moon roof is operated continuously in the same direction, the current flowing to the motor is cut off when the time shown below has elapsed after the motor operation has been started. ∗ Slide open/close operation by the moon roof SW approx. 20 seconds ∗ Tilt up/down operation by the moon roof SW approx. 2 second ∗ Slide open operation for reverse movement in case of catching prevention function approx. 20 seconds ∗ Tilt up operation for reverse movement in case of catching prevention function approx. 2 seconds

DOOR LOCK CONTROL SYSTEM OUTLINE 1. MANUAL UNLOCK OPERATION When the door lock control SW of the driver or front passenger door is pressed to unlock side, a signal is input to the instrument ECU TERMINAL DMU, and TERMINAL PMU respectively. Then the current flows from the POWER fuse to D/L (U) relay (Coil side) to instrument ECU TERMINAL DURY to TERMINAL GND1 to GROUND, and turns on the D/L (U) relay and D/L (DU) relay. At the same time, the current flows from the POWER fuse to D/L (U) relay, D/L (DU) relay TERMINAL 5 to TERMINAL 3 to door lock motor and back door lock motor to D/L (L) relay TERMINAL 3 to TERMINAL 4 to GROUND, and unlocks the door. 2. MANUAL LOCK OPERATION When the door lock control SW of the driver or front passenger door is pressed to lock side, a signal is input to the instrument ECU TERMINAL DML, and TERMINAL PML respectively. Then the current flows from the POWER fuse to D/L (L) relay (Coil side) to instrument ECU TERMINAL DLRY to TERMINAL GND1 to GROUND. This turns on the D/L (L) relay and the current flows from the POWER fuse to D/L (L) relay TERMINAL 5 to TERMINAL 3 to door lock motor and back door lock motor to D/L (U) relay, D/L (DU) relay TERMINAL 3 to TERMINAL 4 to GROUND, and locks the door. 3. DOOR KEY UNLOCK OPERATION ∗ Unlock operation from driver door When the door is unlocked once by the ignition key from the driver side, a signal is input from door key lock and unlock SW LH to instrument ECU TERMINAL DKU. As a result, the instrument ECU operates and the current flows from POWER fuse to D/L (DU) relay (Coil side) to instrument ECU TERMINAL DDRY to TERMINAL GND1 to GROUND, and turns on the D/L (DU) relay. At the same time, the current flows from the POWER fuse to D/L (DU) relay TERMINAL 5 to TERMINAL 3 to door lock motor front LH to D/L (L) relay TERMINAL 3 to TERMINAL 4 to GROUND, and unlocks the driver door only. Accordingly, if the second unlock operation is made within 3 seconds , a signal is input to instrument ECU TERMINAL DKU, and the current flows as manual unlock operation, and unlocks all the doors. ∗ Unlock operation from front passenger or back door When the front passenger door or back door is unlocked using the ignition key, a signal from the door key lock and unlock SW RH and/or back door key lock and unlock SW is input to instrument ECU TERMINAL PKU. As a result, the current flows as manual unlock operation and unlocks all the doors at once. 4. IGNITION KEY REMINDER OPERATION When the door is locked using the door lock knob with the ignition key remaining in the key cylinder and door opened, it is automatically unlocked. Additionally, if lock operation is made by the door lock control SW or door key lock SW, after the lock operation is completed, the doors are unlocked automatically.

WIRELESS DOOR LOCK CONTROL SYSTEM OUTLINE In this system, the wireless door lock ECU receivers weak radio wave transmitted from the transmitter built–into the ignition key, and outputs a signal to the instrument ECU. Accordingly, all the doors are can be locked and unlocked by remote control. 1. NORMAL OPERATION ∗ Lock operation When the lock SW on the transmitter is pressed, all the doors are locked. ∗ Unlock operation When the unlock SW on the transmitter is pressed once, only the driver door is unlocked. When the unlock SW is pressed again within 3 seconds, all the doors are unlocked. 2. AUTO LOCK FUNCTION When the door is not actually opened within 30 seconds after the door has been unlocked by the unlock SW on the transmitter, all the doors are automatically locked. If any of the following conditions are detected, the wireless door lock does not function. ∗ Any door is opened. ∗ The ignition key is inserted into the ignition SW. ∗ When the unlock detection SW of all the doors are locked. 3. WIRELESS DOOR LOCK STOP FUNCTION If any of the following conditions are detected, the wireless door lock does not function. Lock operation ∗ When any door is open (Door courtesy SW on) ∗ The ignition key is inserted into the ignition SW (Unlock warning SW on) ∗ Ignition SW is on Unlock operation ∗ Ignition SW is on 4. BUZZER SOUND FUNCTION During lock operation, when the wireless door lock ECU receives a lock signal from the door unlock detection SW, the wireless door lock buzzer goes on once. During unlock operation, when the wireless door lock ECU receives an unlock signal from the door unlock detection SW, the wireless door lock buzzer goes on twice. With any door open, when the wireless door lock ECU receives a lock signal from the transmitter, the wireless door lock buzzer goes on for approx. 10 seconds. If the door is closed, or if the unlock signal is received from the transmitter while the buzzer is on, the buzzer stops. 5. VISUAL CONFIRMATION OF LOCK OR UNLOCK During lock operation, when the wireless door lock ECU receives a lock signal from the door unlock detection SW, the taillight and parking light is flashed once. During unlock operation, when the wireless door lock ECU receives an unlock signal from the door unlock detection SW, the taillight and parking light is flashed twice. 6. PANIC MODE FUNCTION When the panic SW on the transmitter is pressed, the wireless door lock ECU receives a signal and enters the panic mode. The signal input into the theft deterrent ECU from the wireless door lock ECU turns on the theft deterrent horn, and flashes the taillight and headlight. When the panic SW or the unlock SW of the transmitter is pressed during the panic mode, the panic mode is canceled, and the theft deterrent horn stops, and the taillight and headlight are turned off. 7. REPEAT FUNCTION If the lock detection signal in response to the output signal is not received after the wireless door lock ECU has output the lock signal, the lock signal is output again.

SYSTEM OUTLINE 1. MANUAL SLIDE OPERATION (DRIVER’S SEAT) When the slide SW is pressed to the front side, a signal is input to the power seat ECU TERMINAL (A) 15. This activates the power seat ECU and the current flows from power seat ECU TERMINAL (B) 4 to power seat motor (Driver’s seat slide control) TERMINAL 2 to TERMINAL 1 to power seat ECU TERMINAL (B) 3 to GROUND, and the seat slides forward while the slide SW is kept pressed. When the slide SW is pressed to the rear side, a signal is input to the power seat ECU TERMINAL (A) 16, and the current flows from power seat ECU TERMINAL (B) 3 to power seat motor (Driver’s seat slide control) TERMINAL 1 to TERMINAL 2 to power seat ECU TERMINAL (B) 4 to GROUND, and the seat slides backward while the slide SW is kept pressed. At this time, the power seat position sensor (Driver’s seat slide control) constantly detects the position of the seat, and inputs a signal to the power seat ECU TERMINAL (A) 14. 2. MANUAL RECLINING CONTROL (DRIVER’S SEAT) When the reclining SW is pressed to the front side,a signal is input to the power seat ECU TERMINAL (A) 21. This activates the power seat ECU and the current flows from power seat ECU TERMINAL (B) 2 to power seat motor (Driver’s seat reclining control) TERMINAL 2 to TERMINAL 1 to power seat ECU TERMINAL (B) 1 to GROUND, and the seat back reclines forward while the reclining SW is kept pressed. When the reclining SW is pressed to the rear side,a signal is input to the power seat ECU TERMINAL (A) 22, and the current flows from power seat ECU TERMINAL (B) 1 to power seat motor (Driver’s seat reclining control) TERMINAL 1 to TERMINAL 2 to power seat ECU TERMINAL (B) 2 to GROUND, and the seat back reclines backward while the reclining SW is kept pressed. At this time, the power seat position sensor (Driver’s seat reclining control) constantly detects the position of the seat back, and inputs a signal to the power seat ECU TERMINAL (A) 5. 3. MANUAL FRONT VERTICAL CONTROL (DRIVER’S SEAT) When the front side of the front vertical SW is pulled up, a signal is input to the power seat ECU TERMINAL (A) 19. This activates the power seat ECU and the current flows from power seat ECU TERMINAL (B) 10 to power seat motor (Driver’s seat front vertical control) TERMINAL 1 to TERMINAL 2 to power seat ECU TERMINAL (B) 9 to GROUND, and the front side of the seat cushion moves up while the front vertical SW is kept pressed. When the power seat front vertical SW is pressed down, a signal is input to the power seat ECU TERMINAL (A) 7, and the current flows from power seat ECU TERMINAL (B) 9 to power seat motor (Driver’s seat front vertical control) TERMINAL 2 to TERMINAL 1 to power seat ECU TERMINAL (B) 10 to GROUND, and the front side of the seat cushion moves down while the front vertical SW is kept pressed. At this time, the power seat position sensor (Driver’s seat front vertical control) constantly detects the position of the seat cushion (front side), and inputs a signal to the power seat ECU TERMINAL (A) 3. 4. MANUAL REAR VERTICAL OPERATION (DRIVER’S SEAT) When the rear side of the rear vertical SW is pulled up, a signal is input to the power seat ECU TERMINAL (A) 17. This activates the power seat ECU and the current flows from power seat ECU TERMINAL (B) 6 to power seat motor (Driver’s seat rear vertical control) TERMINAL 1 to TERMINAL 2 to power seat ECU TERMINAL (B) 5 to GROUND, and the all seat moves up while the rear vertical SW is kept pressed. When the rear vertical SW is pressed down, a signal is input to the power seat ECU TERMINAL (A) 18, and the current flows from power seat ECU TERMINAL (B) 5 to power seat motor (Driver’s seat rear vertical control) TERMINAL 2 to TERMINAL 1 to power seat ECU TERMINAL (B) 6 to GROUND, and the all seat moves down while the rear vertical SW is kept pressed. At this time, the power seat position sensor (Driver’s seat rear vertical control) constantly detects the position of the all seat, and inputs a signal to the power seat ECU TERMINAL (A) 4. 5. MANUAL LUMBAR SUPPORT OPERATION (DRIVER’S SEAT) When the lumbar support control SW (Driver’s seat) is pressed to the front side, the current from the POWER fuse flows to the lumbar support control SW (Driver’s seat) TERMINAL 4 to TERMINAL 1 to power seat motor (Driver’s seat lumbar support control) TERMINAL 1 to TERMINAL 2 to lumbar support control SW (Driver’s seat) TERMINAL 2 to TERMINAL 3 to GROUND, and the lumbar support moves forward. When the lumbar support control SW (Driver’s seat) is pressed to the rear side, the current from the POWER fuse flows to the lumbar support control SW (Driver’s seat) TERMINAL 4 to TERMINAL 2 to power seat motor (Driver’s seat lumbar support control) TERMINAL 2 to TERMINAL 1 to lumbar support control SW (Driver’s seat) TERMINAL 1 to TERMINAL 3 to GROUND, and the lumbar support moves backward. 6. DRIVING POSITION MEMORY FUNCTION (DRIVER’S SEAT) The seat motor rotation amount (How much the seat has been moved) is detected by the position sensor, and is input into the power seat ECU. The driving position memory SW allows recording and recalling the seat position memory. The recording and recalling is controlled through the communication control among the instrument ECU, tilt and telescopic ECU, remote control mirror ECU etc.

P24 POWER SEAT ECU

SYSTEM OUTLINE This system provides the automatic tilt and telescopic mechanisms using the motor drive, tilt and telescopic ECU control, allowing variable steering movement in the back and forth, and vertical directions. This makes it possible to set the steering to the desired steering position, and move the steering to a position where the driver can easily get off the vehicle, allowing easier seating. Additionally, by linking the power seat and remote control mirror, an optimal driving position corresponding to the driver’s needs can be stored into the memory. 1. AUTO RETURN OPERATION When the ignition key is inserted into the key cylinder (Unlock warning SW on), a signal is input to the tilt and telescopic ECU through communication control of the instrument ECU etc. This activates the tilt and telescopic ECU to automatically return the steering to the position set before the ignition key has been removed. 2. AUTO AWAY OPERATION When the ignition key is turned from on to off and removed from the key cylinder (Unlock warning SW off), a signal is input to the tilt and telescopic ECU through communication control of the instrument ECU etc. This activates the tilt and telescopic ECU to automatically move the steering to the top tilt step position and maximum telescopic retract position. 3. MANUAL OPERATION The tilt and telescopic can be adjusted while the ignition key is inserted into the key cylinder. ∗ Tilt operation When the tilt and telescopic SW is pressed to TILT DOWN position, the current flows from tilt and telescopic ECU TERMINAL (A) 2 to tilt and telescopic SW TERMINAL 9 to TERMINAL 4 to tilt and telescopic ECU TERMINAL (A) 5, and a signal is input to the tilt and telescopic ECU. This activates the tilt and telescopic ECU and rotates the tilt motor to lower the steering while the tilt and telescopic SW is kept pressed to TILT DOWN position. When the tilt and telescopic SW is pressed to TILT UP position, the current flows from tilt and telescopic ECU TERMINAL (A) 2 to tilt and telescopic SW TERMINAL 9 to TERMINAL 4 to tilt and telescopic ECU TERMINAL (A) 5, and a signal is input to the tilt and telescopic ECU. This activates the tilt and telescopic ECU and rotates the tilt motor to raise the steering while the tilt and telescopic SW is kept pressed to TILT UP position. ∗ Telescopic operation When the tilt and telescopic SW is pressed to TELESCO LONG position, the current flows from tilt and telescopic ECU TERMINAL (A) 2 to tilt and telescopic SW TERMINAL 9 to TERMINAL 4 to tilt and telescopic ECU TERMINAL (A) 5, and a signal is input to the tilt and telescopic ECU. This activates the tilt and telescopic ECU and rotates the telescopic motor to extend the telescopic while the tilt and telescopic SW is kept pressed to TELESCO LONG position. When the tilt and telescopic SW is pressed to TELESCO SHORT position, the current flows from tilt and telescopic ECU TERMINAL (A) 2 to tilt and telescopic SW TERMINAL 9 to TERMINAL 4 to tilt and telescopic ECU TERMINAL (A) 5, and a signal is input to the tilt and telescopic ECU. This activates the tilt and telescopic ECU and rotates the telescopic motor to retract the telescopic while the tilt and telescopic SW is kept pressed to TELESCO SHORT position. 4. DRIVING POSITION MEMORY FUNCTION The pulse signals detected by the tilt and telescopic sensors are input to the tilt and telescopic ECU. This makes it possible to store and recall the desired driving position through communication control of the instrument ECU.

SYSTEM OUTLINE When the ignition SW is turned on, the outer mirrors can be operated. When the remote control mirror SW is operated, a signal is input to the remote control mirror ECU, and the outer mirror can be adjusted to the desired position. In this system, the position sensor detects the number of rotations of each motor (Movement amount of each mirror) and inputs it to the remote control mirror ECU. This makes it possible to store and recall the outer mirror position using the driving position memory SW. The outer mirror position is stored and recalled through communication control of the instrument ECU. When the remote control mirror SW (Select SW) is moved to the left side from neutral position, while the ignition SW is on and the shift lever is in R position, the outer mirror LH, RH moves downward a little bit. In this case, it is not necessary to operate the remote control mirror SW for approx. 120 seconds.

SYSTEM OUTLINE 1. SEAT BELT WARNING SYSTEM When the ignition SW turned on, a signal is input to the combination meter and center ECU. To determine whether the driver has fastened the seat belt, a signal is input from the buckle SW LH to the combination meter TERMINAL (A) 16. When the seat belt is not fastened, the seat belt warning light in the combination meter blinks, and emits a warning sound. In addition, the front passenger is recognized by a sensor (Seat belt warning occupant detection sensor) is installed in the front passenger seat, and determines whether the seat belt is fastened. When not fastened, the signals from the seat belt warning occupant detection sensor and buckle SW RH is input to center ECU TERMINAL 16, and the passenger seat belt warning light blinks to warn the passenger. 2. KEY REMINDER SYSTEM When the driver door is opened with the ignition SW off and ignition key remaining in the key cylinder (Unlock warning SW on), a signal is input from the unlock warning SW to the combination meter TERMINAL (A) 10, and from the door courtesy SW front LH to combination meter TERMINAL (A) 19. As a result, the buzzer in the combination meter goes on and warns the driver that the key is remaining in the key cylinder.

CONDENSER FAN AND FRONT AIR CONDITIONING SYSTEM OUTLINE 1. HEATER BLOWER OPERATION Manual operation When the blower speed is set ant any speed by the blower control SW, the center ECU sends a signal to the blower motor controller, and controls the blower motor speed. Auto operation When the auto SW is operated, the center ECU sends signals to the blower motor controller, according to the signals from respective sensors, commands from the temperature SW etc., and controls the blower motor automatically. 2. AIR INLET CONTROL SERVO MOTOR CONTROL When the FRESH/RECIRC select SW is switched to RECIRC, the motor in the air inlet control servo motor rotates to move the damper to the RECIRC side. The damper position is recognized by the center ECU TERMINAL TPI, and rotates the motor until the damper reaches its position. When the FRESH/RECIRC select SW is switched to FRESH, the motor in the air inlet control servo motor rotates to move the damper to the FRESH side. The damper position is recognized by the center ECU TERMINAL TPI, and rotates the motor until the damper reaches its position. When the FRESH/RECIRC select SW is set to auto, the exhaust gas sensor in the engine room detects the ingredient of the exhaust emission, and switches the FRESH/RECIRC mode automatically. 3. AIR VENT MODE CONTROL SERVO MOTOR When the mode select SW in the center ECU is pushed, a signal is sent from the center ECU, and activates the air vent mode control servo motor. This causes the servo motor to rotate to the position selected using the mode select SW (FACE, BI–LEVEL, FOOT, FOOT/DEF, DEF), and moves the damper. 4. AIR MIX CONTROL SERVO MOTOR When the temperature control SW in the center ECU is pushed, a signal is sent from the center ECU, and activates the air mix control servo motor. The motor and damper is moved until it reaches the temperature set by the temperature control SW. 5. AIR CONDITIONING OPERATION The center ECU receives various signals, i. e., the engine RPM from the crankshaft position sensor, outlet temperature from the A/C ambient temp. sensor, coolant temperature from the engine coolant temp. sensor, and the lock signal from the A/C compressor, etc. When the engine is started and the A/C SW is turned on, a signal is sent to the center ECU. As a result, the magnetic clutch is turned on and operates the compressor. In addition, when the engine control module detects that the magnetic clutch is on and the A/C compressor is operating, it controls the engine in the direction to avoid lowering the engine RPM during A/C operation. When any of the following signals are sent to the center ECU, the A/C is turned off. ∗ Coolant temp. is high. ∗ Outlet air temp. is low. ∗ Large difference between the engine speed and compressor speed. ∗ The refrigerant pressure is abnormally high or low. 6. CONDENSER FAN MOTOR OPERATION When the A/C is operating and the A/C single pressure SW is on, the current flows from the A.C fuse to MG CLT relay TERMINAL 5 to TERMINAL 3 to A/C condenser fan relay TERMINAL 3 to TERMINAL 4 to A/C single pressure SW TERMINAL 2 to TERMINAL 3 to GROUND, and turns on the A/C condenser fan relay. As a result, the current flows from the CDS FAN fuse to A/C condenser fan relay TERMINAL 1 to TERMINAL 2 to A/C condenser fan motor TERMINAL 2 to TERMINAL 1 to GROUND, and operates the A/C condenser fan motor.
