HOW TO USE THIS MANUAL B
This manual provides information on the electrical circuits installed on vehicles bydividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the powersource is received from the battery as far as each ground point. (All circuitdiagrams are shown with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuitwhere the problem was detected (see System Circuit section), the power sourcesupplying power to that circuit (see Power Source section), and the ground points(see Ground Point section). See the System Outline to understand the circuitoperation.
When the circuit operation is understood, begin troubleshooting of the problemcircuit to isolate the cause. Use Relay Location and Electrical Wiring Routingsections to find each part, junction block and wiring harness connectors, wiringharness and wiring harness connectors, splice points, and ground points of eachsystem circuit. Internal wiring for each junction block is also provided for betterunderstanding 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 ElectricalWiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL
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 flowsthrough the rear lights warning light to TERMINAL 4 of the light failure sensor.
Stop Light Disconnection WarningWhen the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the currentflowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects thedisconnection 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 lightswarning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warningcircuit on and holds the warning light on until the ignition SW is turned off.

E GLOSSARY OF TERMS AND SYMBOLS
BATTERYStores chemical energy andconverts it into electrical energy.Provides DC current for the auto’svarious electrical circuits.
GROUNDThe point at which wiring attaches tothe Body, thereby providing a returnpath for an electrical circuit; without aground, current cannot flow.
CAPACITOR (Condenser)A small holding unit for temporarystorage of electrical voltage.
HEADLIGHTSCurrent flow causes a headlightfilament to heat up and emit light. Aheadlight may have either a single(1) filament or a double (2) filament
1. SINGLE FILAMENT
CIGARETTE LIGHTERAn electric resistance heatingelement.
2. DOUBLE FILAMENT
CIRCUIT BREAKERBasically a reusable fuse, a circuitbreaker will heat and open if toomuch current flows through it.Some units automatically reset whencool, others must be manually reset.
HORNAn electric device which sounds aloud audible signal.
DIODEA semiconductor which allowscurrent flow in only one direction.
IGNITION COILConverts low-voltage DC currentinto high-voltage ignition current forfiring the spark plugs.
DIODE, ZENERA diode which allows current flow in onedirection but blocks reverse flow only upto a specific voltage. Above that potential,it passes the excess voltage. This acts asa simple voltage regulator.
LIGHTCurrent flow through a filamentcauses the filament to heat up andemit light.
PHOTODIODEThe photodiode is a semiconductorwhich controls the current flowaccording to the amount of light.
LED (LIGHT EMITTING DIODE)Upon current flow, these diodes emitlight without producing the heat of acomparable light.
DISTRIBUTOR, IIAChannels high-voltage current fromthe ignition coil to the individualspark plugs.
METER, ANALOGCurrent flow activates a magneticcoil which causes a needle to move,thereby providing a relative displayagainst a background calibration.
FUSEA thin metal strip which burns throughwhen too much current flows through it,thereby stopping current flow andprotecting a circuit from damage.
FUSIBLE LINK
METER, DIGITALCurrent flow activates one or manyLED’s, LCD’s, or fluorescentdisplays, which provide a relative ordigital display.
FUEL
FUSIBLE LINKA heavy-gauge wire placed in highamperage circuits which burns through onoverloads, thereby protecting the circuit.The numbers indicate the crosssectionsurface area of the wires.
(for Medium Current Fuse)
(for High Current Fuse or Fusible Link)

Engine Control
The engine control system utilizes a microcomputer and maintains overall control of the engine, transmission etc. An outlineof 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 whichvaries according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the enginecontrol module as a control signal.
(2) Intake air temp. signal circuitThe intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as acontrol signal to TERMINAL THA of the engine control module.
(3) Oxygen sensor signal circuitThe oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensorsto TERMINALS OX1A, OX1B, OX2A, OX2B of the engine control module.
(4) RPM signal circuitThe camshaft position is detected by the camshaft position sensor and is input into TERMINAL G2+ of the enginecontrol module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal isinput into TERMINAL NE+ of the engine control module.
(5) Throttle position sensor signal circuitThe throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINALSVTA1, VTA2 of the engine control module.
(6) Vehicle speed circuitThe vehicle speed sensor (Combination meter) detects the vehicle speed, and the signal is input into TERMINAL SPDof the engine control module via the combination meter.
(7) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, thevoltage for engine control module start up power supply is applied through the EFI OR ECD relay, to TERMINALS +B,+B2 of the engine control module. The current from the IGN fuse flows to TERMINAL IGSW of the engine controlmodule, and voltage is constantly applied to TERMINAL +BM.
(8) Intake air volume signal circuitThe intake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of theengine control module.
(9) Stop light SW signal circuitThe stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP ofthe engine control module as a control signal.
(10)Starter signal circuitTo confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking isdetected, and is input into TERMINAL STA of the engine control module as a control signal.
(11) Engine knock signal circuitEngine knocking is detected by the knock sensors, and is input into TERMINALS KNK1, KNK2 of the engine controlmodule 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 drivingconditions.
∗ ESA systemThe 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. Thecontrol signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5, IGT6, IGT7, IGT8, and these signals control theigniter to provide the best ignition timing.
∗ Heated oxygen sensor heater control systemThe heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaustemission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine controlmodule evaluates the signals from each sensors, and outputs current to TERMINALS HT1A, HT1B, HT2A, HT2B tocontrol the heater.
∗ Fuel pump control systemThe engine control module supplies current to TERMINAL FPR, and controls the operation speed of the fuel pump by theF/PUMP relay.
∗ ACISThe ACIS includes a valve in the bulkhead separating the surge tank into two parts. This valve is opened and closed inaccordance with the driving conditions to control the intake manifold length in two stages, for increased engine output in allranges from low to high speeds.
∗ ETCS-iThe ETCS-i controls the engine output at its optimal level in accordance with the opening of the accelerator pedal, underall driving conditions.
3. Diagnosis SystemWhen there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in thememory. The malfunctioning system can be found by reading the code displayed on the malfunction indicator lamp.
4. Fail-Safe SystemWhen a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued controlbased 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.

When the ignition SW turned on, the current from the WIPER fuse flows to the front wiper and washer SW TERMINAL 17,and the front wiper motor TERMINAL 2.
1. Low PositionWhen the front wiper SW is turned to LO position, the current flows from the front wiper and washer SW TERMINAL 17 toTERMINAL 7 to the front wiper motor TERMINAL 1 to TERMINAL 5 to GROUND, and operates the front wiper motor at lowspeed.
2. High PositionWhen the front wiper SW is turned to HI position, the current flows from the front wiper and washer SW TERMINAL 17 toTERMINAL 8 to the front wiper motor TERMINAL 4 to TERMINAL 5 to GROUND, and operates the front wiper motor at highspeed.
3. INT PositionWhen the front wiper SW is turned to INT position, the relay operates and the current which is connected by the relayfunction 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 theintermittent time is controlled by a time control SW to change the charging time of the condenser.
4. Washer Interlocking OperationWhen the front washer SW is pulled up, the current flows from the washer motor TERMINAL 2 to TERMINAL 3 to the frontwiper and washer SW TERMINAL 11 to TERMINAL 2 to GROUND, operates the washer motor and the window washeremits a water spray. This causes the current to flow to the washer continuous operation circuit in the front wiper and washerSW TERMINAL 11 to TERMINAL 7 to front wiper motor TERMINAL 1 to TERMINAL 5 to GROUND, and operates the wiper.

When the ignition SW is turned on, the current flows from the WASHER fuse to washer motor TERMINAL 2, and the currentflows from the RR WIPER fuse to rear wiper relay TERMINAL 3, and the rear wiper motor TERMINAL 1 respectively.
1. Rear Wiper Normal OperationWhen the ignition SW is turned on, and the rear wiper and washer SW is turned to ON position, the current flows from therear wiper relay TERMINAL 3 to TERMINAL 6 to the rear wiper and washer SW TERMINAL 10 to TERMINAL 2 toGROUND, and turns on the rear wiper relay. As a result, the current flows from the rear wiper relay TERMINAL 3 toTERMINAL 4 to the rear wiper motor TERMINAL 3 to TERMINAL 2 to GROUND, and operates the rear wiper.
2. Rear Wiper Intermittent OperationWhen the ignition SW is turned on, and the rear wiper and washer SW is turned to INT position, the current flows from therear wiper relay TERMINAL 3 to TERMINAL 2 to the rear wiper and washer SW TERMINAL 13 to TERMINAL 2 toGROUND, and the intermittent circuit in the rear wiper relay is controlled to operate the wiper intermittently.
3. Washer OperationWhen the ignition SW is turned on, and the rear wiper and washer SW is turned from OFF to WASH position, the currentflows from the WASHER fuse to the washer motor TERMINAL 2 to TERMINAL 1 to the rear wiper and washer SWTERMINAL 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 wipernormal operation.

Electronically Controlled Transmission and A/T Indicator
Previous automatic transmissions have selected each gear shift using mechanically controlled throttle hydraulic pressure,governor hydraulic pressure and lock-up hydraulic pressure. The electronically controlled transmission, however, electricallycontrols the line pressure, throttle pressure, lock-up pressure and accumulator pressure etc. through the solenoid valve. Theelectronically controlled transmission is a system which precisely controls gear shift timing and lock-up timing in response tothe vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth driving possible byshift 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. Gear Shift OperationWhen driving, the engine warm up condition is input as a signal to TERMINAL THW of the engine control module from theengine coolant temp. sensor and the vehicle speed signal from vehicle speed sensor is input to TERMINAL SP2+ of theengine control module. At the same time, the throttle valve opening signal from the throttle position sensor is input toTERMINALS VTA1 and VTA2 of the engine control module as throttle angle signal.Based on these signals, the engine control module selects the best shift position for the driving conditions and sends currentto the electronically controlled transmission solenoid.
2. Line Hydraulic Pressure ControlThe engine control module adjusts the line hydraulic pressure to the optimal level by controlling TERMINAL SLT+ of themodule according to the engine torque data. This realizes the smooth gear shifting.
3. High Response Gear Shifting ControlThe engine control module performs the high response engine torque up control to control the ignition-timing lag as well asopening the electronic throttle when shifting down. By doing this, the gear shifting is performed in a short period of time.Moreover, the engine control module uses the orifice switching control, which optimizes the speed of applying and reducingthe hydraulic pressure. And it realizes the fine shifting condition by applying and reducing hydraulic pressure slowly whenthe gear shifting shock is important and quickly when the high response is required.
4. Clutch Hydraulic Pressure ControlThe engine control module controls the clutch operation in the optimal timing and with the best hydraulic pressure accordingto the engine torque data and the number of the clutch revolution
5. Lock-Up and Flexible Lock-Up ControlThe engine control module carries out the lock-up control by controlling the TERMINAL SLU+ of the module according tothe shift position, vehicle speed, throttle opening degree and running conditions. The engine control module also steadilykeeps applying the lock-up clutch a delicate slippage to improve the transmission efficiency (Fuel efficiency) of the torqueconverter.
6. Stop Light SW CircuitIf the brake pedal is depressed (Stop light SW on) when driving in lock-up condition, a signal is input to TERMINAL STP ofthe engine control module. The engine control module operates and cuts the current to the solenoid to release lock-up.
7. Ai-Shift ControlThe engine control module judges whether the road is downslope or upslope by detecting the throttle opening degree or thevehicle’s speed. Moreover it can expect the winding roads by detecting the turning condition of the vehicle. The enginecontrol module keeps unnecessary shifting up from the fourth gear from operating and carries out the automatic shiftingdown to the third gear in order to control the vehicle running according to the road conditions. The engine control modulealso reads the driver’s intention during driving from his (her) accelerating operation and the running conditions of the vehicle.As a result of that, ideal shifting patters for each driver are automatically selected without any switching operations.
8. Electronically Controlled Transmission Pattern Select SW CircuitWhen the electronically controlled transmission pattern select SW is switched to PWR, a signal is input to TERMINAL PWRof the engine control module. This enables shift-up and shift-down at a higher speed range.
9. Transfer Shift OperationWhen 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.

The cruise control system is a constant vehicle speed controller which controls the opening angle of the engine throttle valveby the SW, and allows driving at a constant speed without depressing the accelerator pedal.
Set OperationWhen the ON-OFF SW is turned on, the systems starts preparations for cruise control and turns on the indicator light in thecombination meter.
Set Speed ControlWhen the - SET SW is operated with the ON-OFF SW turned on during driving, the speed is controlled at a constant speed.
Coast ControlWhen the - SET SW is kept turned on during cruise control driving, the engine control module controls the throttle valve todecelerate the vehicle speed.Every time the - SET SW is turned on instantaneously, the vehicle speed is decelerated approx. 1.5 km/h.
Accel ControlWhen the + RES SW is kept turned on during cruise control driving, the engine control module controls the throttle valve toaccelerate the vehicle speed.Every time the + RES SW is turned on instantaneously, the vehicle speed is accelerated approx. 1.5 km/h.
Resume ControlIf the vehicle speed is within the low speed limit (Approx. 40 km/h, 25 mph) when canceling the cruise control, operation ofthe + RES SW accelerates the vehicle speed and resumes the level before canceling the cruise control.
Manual Cancel MechanismIf 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 ON-OFF SW is turned off
Auto Cancel FunctionIf 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 FunctionThe overdrive may be canceled if the vehicle travels on a upward slope during cruise control driving. After the overdrive iscanceled, if the vehicle speed exceeds the overdrive return speed (Set speed ( 2 km/h, 1.2 mph) ) and it is determined thatthe slope has finished, and the vehicle returns to overdrive mode again.

VSC
1. ABS OperationIf the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of the wheel cylinders for all the fourwheels to automatically avoid wheel locking and ensure the directional and steering stability of the vehicle. If the brake pedalis depressed suddenly, the ABS & BA & TRAC & VSC ECU controls the solenoids in the actuators using the signals from thesensors to move the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If theABS & BA & TRAC & VSC ECU detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls thesolenoids in the actuators to increase the braking pressure.
2. Traction Control OperationThe traction control system controls the engine torque, the hydraulic pressure of the driving wheel cylinders, slipping of thewheels which may occur at start or acceleration of the vehicle, to ensure an optimal driving power and vehicle stabilitycorresponding to the road conditions.
3. VSC OperationUnexpected road conditions, vehicle speed, emergency situation, and any other external factors may cause large under- orover-steering of the vehicle. If this occurs, the VSC system automatically controls the engine power and wheel brakes toreduce 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 dependingon 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 wheelbrakes to reduce the under-steering.VSC indicator lightIf an error occurs in the VSC system, the VSC indicator lights up to warn the driver.
4. Traction Mode and VSC FunctionWhen the center differential of the transfer is locked, the VSC function is turned off. At this time, the VSC OFF indicator lightin the combination meter will come on, and informs the driver that the VSC function is OFF.
5. Mutual System ControlTo efficiently operate the VSC system at its optimal level, the VSC system and other control systems are mutually controlledwhile the VSC system is being operated.Engine throttle controlThe engine power does not interfere with the VSC brake control by controlling the opening of the throttle and reducing theengine output.Engine control and electronically controlled transmission controlThe strong braking force does not interfere with the braking force control of the VSC system by turning off the accel. andreducing changes in the driving torque at shift-down.VSC system operation indicationThe slip indicator light flashes and the buzzer sounds intermittently to warn the driver that the current road is slippery, whilethe VSC system is being operated.
6. Fail Safe FunctionIf an error occurs in the ABS & BA & TRAC & VSC ECU, sensor signals, and/or actuators, the ABS & BA & TRAC & VSCECU 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 openrequest 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 precautionaryinstructions 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 informationwhen 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 thenegative (-) 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 fromdisconnecting 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 becanceled. So before starting work, make a record of the contents memorized in the audio memory system. When work isfinished, reset the audio systems as they were before and adjust the clock. This vehicle has power tilt and powertelescopic 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 necessaryto explain this fact tot the customer, and ask the customer to adjust the features and reset the memory. To avoid erasingthe 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, side airbag assembly, curtain shield airbagassembly, seat belt pretensioner, center airbag sensor assembly, front airbag sensor assembly or side airbag sensorassembly 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 airbagassembly, side airbag assembly, curtain shield airbag assembly, seat belt pretensioner, center airbag sensor assembly,front airbag sensor assembly and side 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, side airbag assembly, curtainshield airbag assembly, seat belt pretensioner, center airbag sensor assembly, front airbag sensor assembly or sideairbag sensor assembly in order to reuse it.
If the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, seatbelt pretensioner, center airbag sensor assembly, front airbag sensor assembly or side airbag sensor assembly hasbeen dropped, or if there are cracks, dents or other defects in the case, bracket or connector, replace them with newones.
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 RepairManual.

SRS
∗ The SRS airbag are provided for the driver and front passenger. The SRS airbags have been designed to help reducingthe shocks to the heads and chests of the driver and front passenger in the event of a severe frontal impact collision assupplements to the seat belts.This system is a 3-sensor type airbag system to detect the impact during a front collision using the center airbag sensorassembly and airbag sensor front LH, RH, and to make the airbag system and pretensioner operate as well.
∗ In this system, a front side collision is detected by the side airbag sensor front LH, RH in order to simultaneously deploythe side and curtain shield airbags. A rear side collision is detected by the side airbag sensor rear LH, RH in order todeploy only the curtain shield airbag.
∗ Roll sensing of curtain shield airbags control has been adopted in order to deploy the curtain shield airbags and thepretensioners for the driver and front passenger, in the event that the vehicle rolls over.A roll sensing of curtain shield airbags cutoff SW is provided on the driver side of the instrument panel to enable the driverto disable this system.
∗ Dual-stage SRS airbags system, that controls the airbag inflating output optimum by judging the extent of impact and seatposition (Driver seat), has been used for the driver and front passenger airbags.
∗ In accordance with the adoption of the dual-stage SRS airbag system, a seat position sensor has been established for thedriver seat.
∗ This system has adopted a fuel cut control that stops the fuel pump when the airbag is deployed.

1. Shift Lock MechanismWhen the brake pedal is depressed with the ignition SW is turned on (Stop light SW on), the shift lock control ECU isactivated and allows the driver to change the shift lever to a position other than P position.
2. Key Interlock MechanismWhen the ignition SW is turned on and the shift lever is at a position other than P position, shift lock control ECU is activatedto flow current to the key interlock solenoid. This inhibits to turn the ignition SW from on to OFF position.

Power Window
1. Manual Down or Up OperationWhen the power window master SW is pressed one step, the current flows from the power window master SW TERMINALDN to the power window motor front LH to the power window master SW TERMINAL UP to GROUND, and rotates the motorto open the window.When the power window master SW is pulled one step, the current flows from the power window master SW TERMINAL UPto the power window motor front LH to the power window master SW TERMINAL DN to GROUND, and rotates the motor toclose the window.For the other windows, as the power window master SW and the power window SW is operated, the relevant door window isopened or closed.
2. Auto Down or Up OperationWhen the power window master SW is pushed two steps, the power window master SW determines it is in auto mode andthe current flows from the power window master SW TERMINAL DN to the power window motor front LH to the powerwindow master SW TERMINAL UP 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 thecurrent flows from the power window master SW TERMINAL UP to the power window motor front LH to the power windowmaster SW TERMINAL DN 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 isautomatically opened/closed.
3. Catching Prevention FunctionWhen any foreign matter is caught in the window during power window up operation, the pulse sensor in the power windowmotor detects the changes in the number of motor rotations and forcibly opens the door window 50 mm, or when the windowopening is less than 200 mm, it opens the window until the opening is 200 mm.
4. Key Off Power Window OperationIt 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 43seconds have not elapsed.

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 the SUN ROOF fuse to the moon roof control ECU TERMINAL 5 of the moon roof controlECU.When the ignition SW is turned on, the current flows from the ECU-IG1 fuse to TERMINAL 8 of the moon roof control ECU.
1. Slide Open OperationWhen the moon roof control SW is kept pressed to OPEN position for approx. 0.3 seconds or longer (Limit SW No.1 off, limitSW No.2 on), a signal is input from the moon roof control SW TERMINAL 5 to the moon roof control ECU TERMINAL 9. Thisactivates the moon roof control ECU and rotates the motor to open the moon roof automatically. However, in case ofpressing the moon roof control SW for 0.3 seconds or less, the moon roof can be operated manually. Then, when the limitSW 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 whilethe moon roof is being opened, the moon roof control ECU is activated to stop the moon roof operation. In addition, when themoon roof is tilted up, the slide open operation does not function.
2. Slide Close OperationWhen 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 the moon roof control SW TERMINAL 4 to the moon roof control ECU TERMINAL10. This activates the moon roof control ECU and rotates the motor to close the moon roof automatically. However, in case ofpressing the moon roof control SW for 0.3 seconds or less, the moon roof can be operated manually. Then, when the limitSW No.2 is turned on, the pulse signal sent from the HALL IC activates the moon roof control ECU, and determines that themoon roof is closed fully, and stops the motor. If other operation SW or the close SW is operated while the moon roof isbeing closed, the moon roof control ECU is activated to stop the moon roof operation.
3. Tilt Up OperationWhen the moon roof control SW is kept pressed to UP position for approx. 0.3 seconds or longer (Limit SW No.1 off, limit SWNo.2 on), a signal is input from the moon roof control SW TERMINAL 1 to the moon roof control ECU TERMINAL 4. Thisactivates the moon roof control ECU and rotates the motor to tilt up the moon roof automatically. If the pulse signal is notinput from the HALL IC for 0.5 seconds or longer, it determines that the moon roof is fully tilted up, and stops the motor. Ifother operation SW or the tilt up SW is operated while the moon roof is being tilted up, the moon roof control ECU isactivated to stop the moon roof operation. In addition, when the moon roof is opened, the tilt up operation does not function.
4. Tilt Down OperationWhen the moon roof control SW is kept pressed to DOWN position for approx. 0.3 seconds or longer (Limit SW No.1 on, limitSW No.2 on), a signal is input from the moon roof control SW TERMINAL 2 to the moon roof control ECU TERMINAL 3. Thisactivates 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, anddetermines 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 isactivated to stop the moon roof operation.
5. Catching Prevention FunctionDuring slide close or tilt down operation, if the moon roof control ECU detects a catching load from the changes in therotation 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 operationIf a catching load is detected, the moon roof is moved in the reverse direction until fully tilted up.
6. Key Off Moon Roof OperationWithin approx. 43 seconds after the ignition SW is turned from on to off, the moon roof can be operated. However, if thedriver or front passenger door is opened during this period of time, the moon roof operation is stopped even though 43seconds have not elapsed.
7. Fail-Safe FunctionIf the moon roof is operated continuously in the same direction, the current flowing to the motor is cut off when the timeshown 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

Air Conditioning (Front)
1. Heater Blower OperationManual operationWhen the blower speed is set ant any speed by the blower control SW, the A/C control assembly sends a signal to theblower motor controller, and controls the blower motor speed.Auto operationWhen the auto SW is operated, the A/C control assembly sends signals to the blower motor controller, according to thesignals from respective sensors, commands from the temperature SW etc., and controls the blower motor automatically.
2. Air Inlet Control Servo Motor ControlWhen the FRESH/RECIRC select SW is switched to RECIRC, the motor in the air inlet control servo motor rotates to movethe damper to the RECIRC side. The damper position is recognized by the A/C control assembly TERMINAL TPI, androtates 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 movethe damper to the FRESH side. The damper position is recognized by the A/C control assembly TERMINAL TPI, and rotatesthe 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 theexhaust emission, and switches the FRESH/RECIRC mode automatically.
3. Air Vent Mode Control Servo MotorWhen the mode select SW in the A/C control assembly is pushed, a signal is sent from the A/C control assembly, andactivates the air vent mode control servo motor. This causes the servo motor to rotate to the position selected using themode select SW (FACE, BI-LEVEL, FOOT, FOOT/DEF, DEF), and moves the damper.
4. Air Mix Control Servo MotorWhen the temperature control SW in the A/C control assembly is pushed, a signal is sent from the A/C control assembly, andactivates the air mix control servo motor. The motor and damper is moved until it reaches the temperature set by thetemperature control SW.
5. Air Conditioning OperationThe A/C control assembly receives various signals, i. e., the engine RPM from the crankshaft position sensor, outlettemperature from the A/C ambient temp. sensor, coolant temperature from the engine coolant temp. sensor, and the locksignal 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 A/Ccontrol assembly. 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, itcontrols 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 A/C control assembly, 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.

VOLTAGE CHECK
(a) Establish conditions in which voltage is present at the checkpoint.Example:
[A] - Ignition SW on[B] - Ignition SW and SW 1 on[C] - Ignition SW, SW 1 and Relay on (SW 2 off)
(b) Using a voltmeter, connect the negative lead to a good groundpoint or negative battery terminal, and the positive lead to theconnector or component terminal.This check can be done with a test light instead of a voltmeter.
CONTINUITY AND RESISTANCE CHECK
(a) Disconnect the battery terminal or wire so there is no voltagebetween the check points.
(b) Contact the two leads of an ohmmeter to each of the checkpoints.
If the circuit has diodes, reverse the two leads and checkagain.When contacting the negative lead to the diode positive sideand the positive lead to the negative side, there should becontinuity.When contacting the two leads in reverse, there should be nocontinuity.
(c) Use a volt/ohmmeter with high impedance (10 kΩ/Vminimum) for troubleshooting of the electrical circuit.

FINDING A SHORT CIRCUIT
(a) Remove the blown fuse and disconnect all loads of the fuse.(b) Connect a test light in place of the fuse.(c) Establish conditions in which the test light comes on.
Example:[A] - Ignition SW on[B] - Ignition SW and SW 1 on[C] - Ignition SW, SW 1 and Relay on (Connect the
Relay) and SW 2 off (or Disconnect SW 2)
(d) Disconnect and reconnect the connectors while watching thetest light.The short lies between the connector where the test lightstays lit and the connector where the light goes out.
(e) Find the exact location of the short by lightly shaking theproblem wire along the body.
CAUTION:(a) Do not open the cover or the case of the ECU unless
absolutely necessary. (If the IC terminals are touched,the IC may be destroyed by static electricity.)
(b) When replacing the internal mechanism (ECU part) ofthe digital meter, be careful that no part of your body orclothing comes in contact with the terminals of leadsfrom the IC, etc. of the replacement part (spare part).
DISCONNECTION OF MALE AND FEMALECONNECTORS
To pull apart the connectors, pull on the connector itself, notthe wire harness.
HINT : Check to see what kind of connector you aredisconnecting before pulling apart.
