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.

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.

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.

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)

MOTORA power unit which convertselectrical energy into mechanicalenergy, especially rotary motion.

1. NORMALLY OPEN

2. NORMALLY CLOSED

RESISTORAn electrical component with a fixedresistance, placed in a circuit toreduce voltage to a specific value.

SWITCH, DOUBLE THROWA switch which continuously passescurrent through one set of contactsor the other.

RESISTOR, TAPPEDA resistor which supplies two ormore different non adjustableresistance values.

SWITCH, IGNITIONA key operated switch with severalpositions which allows variouscircuits, particularly the primaryignition circuit, to becomeoperational.

RESISTOR, VARIABLE or RHEOSTATA controllable resistor with a variablerate of resistance.Also called a potentiometer orrheostat.

SENSOR (Thermistor)A resistor which varies its resistancewith temperature.

SWITCH, WIPER PARKAutomatically returns wipers to thestop position when the wiper switchis turned off.

(Reed Switch Type)

SENSOR, SPEEDUses magnetic impulses to openand close a switch to create a signalfor activation of other components.

TRANSISTORA solidstate device typically used asan electronic relay; stops or passescurrent depending on the voltageapplied at ”base”.

SHORT PINUsed to provide an unbrokenconnection within a junction block.

WIRESWires are always drawn asstraight lines on wiringdiagrams.Crossed wires (1) without ablack dot at the junction are

The engine control system utilizes a microcomputer and maintains overall control of the engine, transmission, etc. An outlineof engine control is given here.

1. INPUT SIGNAL(1) Engine coolant temp. signal system

The engine coolant temp. sensor detects the engine coolant temp. and has a built-in thermistor with a resistance whichvaries according to the water temp. Thus the engine coolant temp. is input in the form of a control signal to TERMINALTHW of the engine control module.

(2) Intake air temp. signal systemThe intake air temp. sensor is installed inside the mass air flow meter and detects the intake air temp., which is input asa control signal to TERMINAL THA of the engine control module.

(3) Heated oxygen sensor signal systemThe oxygen density in the exhaust emissions is detected and input as a control signal to TERMINAL OXS of the enginecontrol module. To maintain stable detection performance by the heated oxygen sensor, a heater is used for warmingthe sensor. The heater is also controlled by the engine control module (HTS).

(4) RPM signal systemCamshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor,camshaft position is input as a control signal to TERMINAL G2 of the engine control module, and engine RPM is input toTERMINAL NE+.

(5) Throttle signal systemThe throttle position sensor detects the throttle valve opening angle, which is input as a control signal to TERMINAL VTAof the engine control module.

(6) Vehicle speed signal systemThe vehicle speed sensor detects the vehicle speed and inputs a control signal to TERMINAL SP1 of the engine controlmodule via the combination meter.

(7) A/C SW signal systemThe operating voltage of the A/C magnetic clutch is detected and input in the form of a control signal to TERMINAL AC1of the engine control module.

(8) Battery signal systemVoltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned to on,voltage for engine control module operation is applied via the EFI relay to TERMINAL +B of the engine control module.

(9) Intake air volume signal systemIntake air volume is detected by the mass air flow meter and a signal is input into TERMINAL VG of the engine controlmodule as a control signal.

(10)Stop light SW signal systemThe stop light SW is used to detect whether or not the vehicle is braking and the information is input as a control signalto TERMINAL STP of the engine control module.

(11) Starter signal systemTo confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input asa control signal to TERMINAL STA of the engine control module.

(12)Engine knock signal systemEngine knocking is detected by the knock sensor 1 and 2 and the signals are input to TERMINALS KNK1 and KNK2 ofthe engine control module.

(13)4WD signal systemWhether or not the vehicle is operating in 4WD mode is determined, and a control signal is input to TERMINAL 4WD ofthe engine control module.

(14)Air fuel ratio signal systemThe air fuel ratio is detected and input as a control signal into TERMINAL AF1+ of the engine control module.

SYSTEM OUTLINE


75

2. CONTROL SYSTEM∗ SFI system

The SFI system monitors the engine conditions through the signals (Input signals (1 to 13) ) input from each sensor tothe engine control module. Based on this data and the program memorized in the engine control module, the mostappropriate fuel injection timing is decided and current is output to TERMINALS #10, #20, #30, #40, #50 and #60 of theengine control module, causing the injectors to operate (to inject fuel). It is this system which, through the work of theengine control module, finely controls fuel injection in response to driving conditions.

∗ Electronic Spark Advance systemThe ESA system monitors the engine conditions using the signals (input signals (1, 4, 5 to 7, 9, 11, 12) ) input to theengine control module from each sensor. Based on this data and the program memorized in the engine control module,the most appropriate ignition timing is decided and current is output to TERMINALS IGT1,IGT2 and IGT3 of the enginecontrol module. This output controls the igniter to produce the most appropriate ignition timing for the driving conditions.

∗ Heated oxygen sensor heater control systemThe heated oxygen sensor heater control system turns the heater to on when the intake air volume is low (Temp. ofexhaust emissions low), and warms up the heated oxygen sensor to improve detection performance of the sensor. Theengine control module evaluates the signals (Input signals (1, 4, 8, 9, 11) ) from each sensor, current is output toTERMINAL HTS and controls the heater.

3. DIAGNOSIS SYSTEMWith the diagnosis system, when there is a malfunction in the ECU signal system, the malfunctioning system is recorded inthe memory. The malfunctioning system can then be found by reading the display (Code) of the malfunction indicator lamp.

4. FAIL-SAFE SYSTEMWhen a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control basedon the signals from that system, the fail-safe system either controls the system by using data (Standard values) recorded inthe engine control module memory or else stops the engine.

(3) Heated oxygen sensor signal systemThe oxygen density in exhaust emissions is detected and input as a control signal to TERMINAL OXS of the enginecontrol module. To maintain stable detection performance by the heated oxygen sensor, a heater is used for warmingthe sensor. The heater is also controlled by the engine control module (HTS).

(4) RPM signal systemCamshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor,camshaft position is input as a control signal to TERMINAL G2+ of the engine control module, and engine RPM is inputto TERMINAL NE+.








(12)Engine knock signal systemEngine knocking is detected by the knock sensor and input as a control signal to TERMINAL KNK of the engine controlmodule.

(13)4WD signal systemWhether or not the vehicle is operating in 4WD mode is determined, and a control signal is input to TERMINAL 4WD ofthe engine control module.

(14)Air fuel ratio signal systemThe air fuel ratio is detected and input as a control signal into TERMINAL AF+ of the engine control module.

SYSTEM OUTLINE


83


The SFI system monitors the engine conditions through the signals (Input signals (1 to 13) ) input from each sensor tothe engine control module. Based on this data and the program memorized in the engine control module, the mostappropriate fuel injection timing is decided and current is output to TERMINALS #10, #20, #30 and #40 of the enginecontrol module, causing the injectors to operate (to inject fuel). It is this system which, through the work of the enginecontrol module, finely controls fuel injection in response to driving conditions.

∗ Electronic spark advance systemThe ESA system monitors the engine conditions using the signals (input signals (1, 4, 5 to 7, 9, 11, 12) ) input to theengine control module from each sensor. Based on this data and the program memorized in the engine control module,the most appropriate ignition timing is decided and current is output to TERMINALS IGT1, IGT2, IGT3 and IGT4 of theengine control module. This output controls the igniter to produce the most appropriate ignition timing for the drivingconditions.

(3) Heated oxygen sensor signal systemThe oxygen density in the exhaust emissions is detected and input as a control signal to TERMINAL OXS of the enginecontrol module. To maintain stable detection performance by the heated oxygen sensor, a heater is used for warmingthe sensor. The heater is also controlled by the engine control module (HTS).

(4) RPM signal systemCamshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor,camshaft position is input as a control signal to TERMINAL G2+ of the engine control module, and engine RPM is inputto TERMINAL NE-.








(12)Engine knock signal systemEngine knocking is detected by the knock sensor and input as a control signal to TERMINAL KNK of the engine controlmodule.

(13)Air fuel ratio signal systemThe air fuel ratio is detected and input as a control signal into TERMINAL AF+ of the engine control module.

SYSTEM OUTLINE


91


The SFI system monitors the engine conditions through the signals (Input signals (1 to 12) ) input from each sensor tothe engine control module. Based on this data and the program memorized in the engine control module, the mostappropriate fuel injection timing is decided and current is output to TERMINALS #10, #20, #30 and #40 of the enginecontrol module, causing the injectors to operate (to inject fuel). It is this system which, through the work of the enginecontrol module, finely controls fuel injection in response to driving conditions.

∗ Electronic spark advance systemThe ESA system monitors the engine conditions using the signals (input signals (1, 4, 5 to 7, 9, 11, 12) ) input to theengine control module from each sensor. Based on this data and the program memorized in the engine control module,the most appropriate ignition timing is decided and current is output to TERMINALS IGT1, IGT2, IGT3 and IGT4 of theengine control module. This output controls the igniter to produce the most appropriate ignition timing for the drivingconditions.

HEADLIGHT (w/ DAYTIME RUNNING LIGHT)

1. DAYTIME RUNNING LIGHT OPERATIONWhen the engine is started, voltage generated at TERMINAL L of the generator is applied to TERMINAL 9 of the daytimerunning light relay (Main).If the parking brake lever is pulled up (The parking brake SW on) at this time, the relay is not activated, so the daytimerunning light system does not operate. If the parking brake lever is then released (The parking brake SW off), a signal isinput to TERMINAL 11 of the relay. This activates the relay, so current flows from battery to the HEAD relay (Point side) toTERMINAL 4 of the DIMMER relay to TERMINAL 1 to HEAD (LO LH), (LO RH) fuse to TERMINAL 1 of the headlights toTERMINAL 3 to TERMINAL 1 of the daytime running light relay (Main) to TERMINAL 2 to GROUND. This causes headlightsto light up (Headlights light up dimmer than full brightness.).Once the daytime running light system operates and headlights light up, headlights remain on even if the parking brake leveris pulled up (The parking brake SW on).If the engine stalls and the ignition SW remains on, headlights remain lighted up even through current is no longer outputfrom TERMINAL L of the generator. If the ignition SW is then turned off, the headlights go off. If the engine is started with theparking brake lever released (The parking brake SW off), the daytime running light system operates and headlights light upwhen the engine starts.

2. HEADLIGHT OPERATIONWhen the light control SW is switched to HEAD position, current flows from the DRL fuse to TERMINAL 4 of the daytimerunning light relay No.4 to TERMINAL 3 to TERMINAL 1 of the diode to TERMINAL 2 to body ECU to TERMINAL 13 of thelight control SW to TERMINAL 16 to GROUND, activating the daytime running light relay No.4. Current then flows from theHEAD (LO LH), (LO RH) fuse to TERMINAL 1 of the headlights to TERMINAL 3 to TERMINAL 2 of the daytime running lightrelay No.4 to TERMINAL 1 to GROUND, causing headlights to light up at normal intensity.When the dimmer SW is switched to HIGH position, the signal from the dimmer SW is input to the daytime running light relay(Main). This activates the relay and current flows from TERMINAL 4 of the DIMMER relay to TERMINAL 2 to TERMINAL 4 ofthe daytime running light relay (Main), activating the DIMMER relay.This causes current to flow from TERMINAL 4 of the DIMMER relay to TERMINAL 3 to HEAD (HI LH), (HI RH) fuse toTERMINAL 2 of the headlights to TERMINAL 3 to TERMINAL 2 of the daytime running light relay No.4 to TERMINAL 1 toGROUND, causing headlights to light up at high beam.When the dimmer SW is switched to FLASH position, the daytime running light relay (Main) is activated and current flowsfrom TERMINAL 4 of the DIMMER relay to TERMINAL 2. Current from the DRL fuse flows TERMINAL 4 of the daytimerunning light relay No.4 to TERMINAL 3 to TERMINAL 1 of the diode to TERMINAL 2 to TERMINAL 8 of the dimmer SW toTERMINAL 16 to GROUND, and also flows from the HEAD (HI LH), (HI RH) fuse to TERMINAL 2 of the headlights toTERMINAL 3 to TERMINAL 2 of the daytime running light relay No.4 to TERMINAL 1 to GROUND, causing the high beam tooperate.

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 governor pressure and lock-up sensor through the solenoid valve. Control of the solenoid valve by the enginecontrol module based on the input signals from each sensor makes smooth driving possible by shift selection for each gearwhich is most appropriate to the driving conditions at that time.

1. GEAR SHIFT OPERATIONDuring driving, the engine control module selects the shift for each gear which is most appropriate to the driving conditions,based on input signals from the engine coolant temp. sensor to TERMINAL THW of the engine control module and also theinput signals to TERMINAL SP2+ of the engine control module from the vehicle speed sensor devoted to the electronicallycontrolled transmission. Current is then output to the electronically controlled transmission solenoid. When shifting to 1stspeed, current flows from TERMINAL S1 of the engine control module to TERMINAL 1 of the electronically controlledtransmission solenoid to GROUND, and continuity to the No.1 solenoid causes the shift.For 2nd speed, current flows from TERMINAL S1 of the engine control module to TERMINAL 1 of the electronicallycontrolled transmission solenoid to GROUND, and from TERMINAL S2 of the engine control module to TERMINAL 2 of theelectronically controlled transmission solenoid to GROUND. And continuity to solenoid No.1 and No.2 causes the shift.For 3rd speed, there is no continuity to No.1 solenoid, only to No.2 causing the shift. Shifting into 4th speed (Overdrive)takes place when there is no continuity to either No.1 or No.2 solenoid.

2. LOCK-UP OPERATIONWhen the engine control module judges from each signal that lock-up operation conditions have been met, current flowsfrom TERMINAL SL of the engine control module to TERMINAL 3 of the electronically controlled transmission solenoid toGROUND, causing continuity to the lock-up solenoid and causing lock-up operation.

3. 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 continuity to the lock-up solenoid is cut.

4. OVERDRIVE CIRCUIT∗ O/D main SW on

When the O/D main SW is turned on, a signal is input to TERMINAL ODMS of the engine control module and enginecontrol module operation causes gear shift when the conditions for overdrive are met.

∗ O/D main SW offWhen the O/D main SW is turned off, a signal is input into TERMINAL ODMS of the engine control module, and turns onthe O/D off indicator light. This activates the ECU, and the transmission system is controlled not to shift to overdrive.

5. A/T OIL TEMP. WARNINGWhen the A/T oil temp. sensor affixed to the transmission case detects that the fluid temp. is 150°C (302°F) or more, theengine control module operates and the current flowing through the GAUGE fuse flows to the A/T oil temp. warning light toTERMINAL OILW of the engine control module to GROUND, so that the warning light lights up, informing that the oil temp. ishigh. When the oil temp. drops to 120°C (248°F) or less, the engine control module stops operating and the warning lightgoes out.

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 governor pressure and lock-up pressure through the solenoid valve. Control of the solenoid valve by the enginecontrol module based on the input signals from each sensor makes smooth driving possible by shift selection for each gearwhich is most appropriate to the driving conditions at that time.

1. GEAR SHIFT OPERATIONDuring driving, the engine control module selects the shift for each gear which is most appropriate to the driving conditions,based on input signals from the engine coolant temp. sensor to TERMINAL THW of the engine control module, and also theinput signals to TERMINAL SP2+ of the engine control module from the vehicle speed sensor devoted to the electronicallycontrolled transmission. Current is then output to the electronically controlled transmission solenoid. When shifting to 1stspeed, current flows from TERMINAL S1 of the engine control module to TERMINAL 1 of the electronically controlledtransmission solenoid to GROUND, and continuity to the No.1 solenoid causes the shift.For 2nd speed, current flows from TERMINAL S1 of the engine control module to TERMINAL 1 of the electronicallycontrolled transmission solenoid to GROUND, and from TERMINAL S2 of the engine control module to TERMINAL 2 of theelectronically controlled transmission solenoid to GROUND, and continuity to solenoid No.1 and No.2 causes the shift.For 3rd speed, there is no continuity to No.1 solenoid, only to No.2 causing the shift. Shifting into 4th speed (Overdrive)takes place when there is no continuity to either No.1 or No.2 solenoid.

2. LOCK-UP OPERATIONWhen the engine control module judges from each signal that lock-up operation conditions have been met, current flowsfrom TERMINAL SL of the engine control module to TERMINAL 3 of the electronically controlled transmission solenoid toGROUND, causing continuity to the lock-up solenoid and causing lock-up operation.

3. 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 continuity to the lock-up solenoid is cut.

4. OVERDRIVE CIRCUIT∗ O/D main SW on

When the O/D main SW is turned on, a signal is input to TERMINAL ODMS of the engine control module and enginecontrol module operation causes gear shift when the conditions for overdrive are met.

∗ O/D main SW offWhen the O/D main SW is turned off, a signal is input into TERMINAL ODMS of the engine control module, and turns onthe O/D off indicator light. This activates the ECU, and the transmission system is controlled not to shift to overdrive.

CRUISE CONTROL

With the ignition SW turned to on, current flows from GAUGE fuse to TERMINAL 1 of the cruise control indicator light andfrom ECU-IG fuse to TERMINAL B of the cruise control ECU. When the ignition SW is on and the cruise control SW isturned on, a signal is input from TERMINAL 5 of the cruise control SW to TERMINAL CCS of the cruise control ECU. As aresult, the cruise control ECU functions and the current to TERMINAL B of the cruise control ECU flows to TERMINAL GNDto GROUND, and the cruise control system is ready for operation.At the same time, the current from the GAUGE fuse flows to TERMINAL 1 of the cruise control indicator light to TERMINAL 8to TERMINAL Pi of the cruise control ECU to TERMINAL GND to GROUND, causing the cruise control indicator light to lightup, indicating that the cruise control is ready for operation.

1. SET OPERATIONWhen the cruise control main SW is turned on and the set SW is pushed with the vehicle speed within the set limit (Approx.40 km/h, 25 mph to 200 km/h, 124 mph), a signal is input to TERMINAL CCS of the cruise control ECU and the vehiclespeed at the time the set SW is released is memorized in the ECU as the set speed.

2. SET SPEED CONTROLDuring cruise control driving, the ECU compares the set speed memorized in the ECU with the actual vehicle speed inputinto TERMINAL SPD of the cruise control ECU from the speedometer, and controls the cruise control actuator to maintainthe set speed.When the actual vehicle speed is lower than the set speed, the ECU causes the current to the cruise control actuator to flowfrom TERMINAL MO of the cruise control ECU to TERMINAL 1 of the cruise control actuator to TERMINAL 2 to TERMINALMC of the cruise control ECU. As a result, the motor in the cruise control actuator is rotated to open the throttle valve and thethrottle cable is pulled to increase the vehicle speed.When the actual vehicle speed is higher than the set speed, the current to the cruise control actuator flows from TERMINALMC of the ECU to TERMINAL 2 of the cruise control actuator to TERMINAL 1 to TERMINAL MO of the cruise control ECU.This causes the motor in the cruise control actuator to rotate to close the throttle valve and return the throttle cable todecrease the vehicle speed.

3. COAST CONTROLDuring cruise control driving, while the coast SW is on, the cruise control actuator returns the throttle cable to close thethrottle valve and decrease the driving speed. The vehicle speed when the coast SW is turned off is memorized and thevehicle continues at the new set speed.

4. ACCEL CONTROLDuring cruise control driving, while the accel SW is turned on, the cruise control actuator pulls the throttle cable to open thethrottle valve and increase the driving speed.The vehicle speed when the accel SW is turned off is memorized and the vehicle continues at the new set speed.

5. RESUME CONTROLUnless the vehicle speed falls below the minimum speed limit (Approx. 45 km/h, 25 mph) after canceling the set speed bythe cancel SW, pushing the resume SW will cause the vehicle to resume the vehicle speed set before cancellation.

6. MANUAL CANCEL MECHANISMIf any of the following operations occurs during cruise control operation, the magnetic clutch of the actuator turns off and themotor rotates to close the throttle valve and the cruise control is released.∗ Placing the shift lever in except D position (A/T) or cruise control clutch SW off (M/T). ”A Signal is not input to TERMINAL D

of the ECU”∗ Depressing the brake pedal (Stop light SW on). ”A Signal is input to TERMINAL STP- of the ECU”∗ Pushing the cancel SW (Cancel SW on). ”A Signal is input to TERMINAL CCS of the ECU”

SYSTEM OUTLINE


133

7. AUTO CANCEL FUNCTION

A) If any of the following operating conditions occurs during cruise control operation, the set speed is erased, the currentflowing to the magnetic clutch is stopped and the cruise control is released (Cruise SW turns off).When this occurs, the ignition SW must be turned off once before the main SW will turn on.

∗ Over current to transistor driving motor and/or magnetic clutch.∗ Current to control the throttle valve in motor becomes always ON.∗ Open circuit in magnetic clutch.∗ Momentary interruption of vehicle speed signal∗ Short circuit in cruise control SW.∗ Motor does not operate despite the motor drive signal being output.

B) If any of the following conditions occurs during cruise control operation, the set speed is erased and the cruise control isreleased. (The power of magnetic clutch is cut off until the set SW is ON again.)

∗ When the vehicle speed falls below the minimum speed limit (approx. 40 km/h, 25 mph)∗ When the vehicle speed falls more than 16 km/h (10 mph) below the set speed, E.G. on an upward slope.∗ When power to the cruise control system is momentarily cut off.

C) If any of the following condition occurs during cruise control operation, the cruise control is released. But in this case, theset speed is not erased. If the vehicle speed is more than the minimum speed limit (Approx. 40 km/h, 25 mph), cruisecontrol operation is possible using SET or RESUME on the control SW.

∗ Open circuit between TERMINAL L of the cruise control ECU and TERMINAL 3 of the stop light SW.

ABS

This system controls the respective brake fluid pressures acting on the disc brake cylinders of the right front wheel, left frontwheel, and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock.This results in improved directional stability and steerability during panic braking.

1. INPUT SIGNAL(1) Speed sensor signal

The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the ABS actuator with ECU.(2) Stop light SW signal

A signal is input to TERMINAL STP of the ABS actuator with ECU when the brake pedal is depressed.(3) Deceleration sensor signal (4WD)

Longitudinal acceleration is detected and a signal is input to the ABS actuator with ECU.

2. SYSTEM OPERATIONDuring sudden braking, the ABS actuator with ECU which has signals input from each sensor lets the hydraulic pressureacting on each wheel cylinder escape to the reservoir.The pump inside the ABS actuator with ECU is also operating at this time and it returns the brake fluid from the reservoir tothe master cylinder, thus preventing locking of vehicle wheels.If the ABS actuator with ECU judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current actingon the solenoid is controlled and the hydraulic pressure is increased.Holding of the hydraulic pressure is also controlled by the ECU, by the same method as above, by repeated pressurereduction. Holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking.

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. To avoid erasing the memory in eachmemory 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, center airbag sensorassembly or front 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 airbagassembly, seat belt pretensioner, center airbag sensor assembly and front 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, centerairbag sensor assembly or front airbag sensor assembly in order to reuse it.

If the steering wheel pad, front passenger airbag assembly, seat belt pretensioner, center airbag sensor assembly orfront airbag sensor assembly has been dropped, or if there are cracks, dents or other defects in the case, bracket orconnector, 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 RepairManual.

SRS

The SRS is a driver protection device which has a supplemental role to the seat belts.When the ignition SW is turned to ACC or ON, the current from the ACC fuse flows to TERMINAL (B) 6 of the center airbagsensor assembly. Only when the ignition SW on, the current from the IGN fuse flows to TERMINAL (B) 5 of the center airbagsensor assembly.If an accident occurs while driving, deceleration caused by a frontal impact is detected (by sensor) and when the frontalimpact exceeds a set level, the current from the ACC or IGN fuse flows to TERMINALS (B) 6 or (B) 5 of the center airbagsensor assembly. This current flows to TERMINAL (B) 14 to TERMINAL 1 of the airbag squib (Steering wheel pad) toTERMINAL 2 to TERMINAL (B) 13 of the center airbag sensor assembly, and also flows to TERMINAL (B) 10 of the centerairbag sensor assembly to TERMINAL 2 of the airbag squib (Front passenger airbag assembly) to TERMINAL 1 of thecenter airbag assembly (Double cab) or TERMINAL (B) 10 of the center airbag sensor assembly to TERMINAL 1 of thepassenger airbag manual on/off SW to TERMINAL 3 to TERMINAL 1 of the airbag squib (Front passenger airbag assembly)to TERMINAL 2 to TERMINAL 2 of the passenger airbag manual on/off SW to TERMINAL 4 to TERMINAL (B) 11 of thecenter airbag sensor assembly (Except double cab). Furthermore, the current flows to TERMINAL (B) 27 or (B) 28 toGROUND, causing the center airbag squibs to expand.When the safing sensor built into the center airbag sensor assembly is on, airbag sensor is off and the current from the ACCor IGN fuse flows same as above-mentioned flowing, causing the airbag squibs to expand. When the safing sensor built intothe center airbag sensor assembly is on, the airbag sensor on one of the above-mentioned circuits is activated so thatcurrent flows to the airbag squibs and causes them to operate.The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.The airbag stored inside the passenger’s instrument panel is instantaneously expanded to soften the shock to thepassenger.

1. FRONT PASSENGER AIRBAG MANUAL ON/OFF OPERATION (EXCEPT DOUBLE CAB)When the passenger airbag manual on/off SW is on, the current flowing from the ACC or IGN fuse to the airbag squib (Frontpassenger airbag assembly) is same as above, causing the airbag squib (Front passenger airbag assembly) to expand in anaccident.If the passenger airbag manual on/off SW is turned to off, the current flows from the ACC fuse to TERMINAL 1 of thepassenger airbag manual on/off indicator to TERMINAL 2 to GROUND, lighting the indicator up. Then the current betweenTERMINAL (B) 11 of the airbag sensor assembly and the airbag squib (Front passenger airbag assembly) is cut off, so that itdoes not expand the airbag squib (Front passenger airbag assembly) in an accident.

The 4WD ECU operates the 2-4 select motor in accordance with the conditions of the 2-4 select SW, the detection SW(Transfer 4WD position) and the detection SW (Transfer L4 position). It also controls the range over which shifting from H2 toH4 is possible based on the vehicle speed sensor. If the 2-4 select SW is pushed in while shifting is prohibited, it causes the4WD indicator light to flash and sounds a warning buzzer to inform the driver. The warning buzzer is built into the ECU. Theoperation of the ECU is as follows.

2-4 SELECT SYSTEMThe 2-4 select system selects between 2WD and 4WD by means of a 2-4 select SW located in the transfer shift lever knobwhich provides good operability.This system uses an ECU which drives the 2-4 select motor in accordance with signals from various sensors andaccomplishes shifting between 2WD and 4WD. Shifting between H4 to L4 is accomplished by operating the transfer shiftlever as before. This system also permits shifting between H2 and H4 without first shifting to H4. All models equipped with2-4 select system are also equipped with the add, explained later.(1) Shifting from H4 to H2

When the 2-4 select SW is turned off, a signal is input to the 2-4 select motor from the 4WD ECU, activating the 2-4select motor so that the transfer changes to 2WD (H2 position).At this time, the detection SW (Transfer 4WD position) and ADD indicator SW are off, so the 4WD indicator light goes off.

(2) Shifting from H2 to H4 (During normal driving)When the 2-4 select SW is turned on, a signal is input to the 2-4 select motor from the 4WD ECU, activating the 2-4select motor so that the transfer changes to 4WD (H4 position)

(3) Shifting from H2 to H4 (High speed driving)The vehicle speed within below approx. 100 km/h, 62 mph, activating the 2-4 select motor so that the transfer changesto 4WD (H4 position)The 4WD ECU stops the signal to the 2-4 select motor with the signal from the vehicle speed sensor. At the same time,it causes the 4WD indicator light to light up and the warning buzzer inside the 4WD ECU to sound.

(4) Shifting to L4When the transfer shift lever is moved to L4 position, the transfer changes to LO position. This turns the detection SW(Transfer L4 position) on, so regardless of whether the 2-4 select SW is on or off, a signal is input to the 2-4 selectmotor from the 4WD ECU, activating the 2-4 select motor so that the transfer changes to 4WD (L4 position) in LOcondition.

REAR DIFFERENTIAL LOCK

This system frees or locks the rear differential according to the position of the rear diff. lock SW. The differential will lock onlywhen the rear diff. lock detection SW is on and the vehicle speed is at 8 km/h (5 mph) or less.When the rear diff. lock SW is switched from OFF position to ON position, current flows to TERMINAL 4 of the rear diff. lockECU. If the limit SW on the lock side inside the rear diff. lock motor is on at this time, until the limit SW is turned off, currentflows from the 4WD fuse to TERMINAL 5 of the rear diff. lock ECU to TERMINAL 3 to TERMINAL 3 of the rear diff. lockmotor to TERMINAL 2 to TERMINAL 2 of the rear diff. lock ECU to TERMINAL 7 to GROUND. This drives the rear diff. lockmotor and locks the rear differential. When the rear differential locks, the rear diff. lock detection SW turns on, lighting up therear diff. lock indicator light in the combination meter.When the rear diff. lock SW is switched from ON position to OFF position, the current to TERMINAL 4 of the rear diff. lockECU is cut off. If the limit SW on the free side inside the rear diff. lock motor is on, until the limit SW is turned off, current flowsfrom the 4WD fuse to TERMINAL 5 of the rear diff. lock ECU to TERMINAL 2 to TERMINAL 2 of the rear diff. lock motor toTERMINAL 3 to TERMINAL 3 of the rear diff. lock ECU to TERMINAL 7 to GROUND. This drives the rear diff. lock motor andfrees the rear differential. When the rear differential is free, the rear diff. lock detection SW and the rear diff. lock indicatorlight in the combination meter are turned off.The rear diff. lock indicator light flashes when:∗ The rear diff. lock SW is switched to ON position during differential lock prohibition conditions (Vehicle speed above 8 km/h

(5 mph) ).∗ The rear diff. lock detection SW is turned off during operation of the rear diff. lock motor.

POWER WINDOW

With the ignition SW turned on, current flows through the ECU-IG fuse to TERMINAL 10 of the body ECU to TERMINAL 2 toTERMINAL 1 of the PWR relay to TERMINAL 2 to GROUND, activating the PWR relay, and the current flowing fromTERMINAL 5 of the PWR relay flows to TERMINAL 3 to TERMINAL (A) 10 (Double cab), (B) 9 (Except double cab) of thepower window master SW and TERMINAL 4 (Front RH), 3 (Rear) of the power window control SW.

1. MANUAL OPERATION (DRIVER’S WINDOW)With the ignition SW turned on and with the power window master SW (Manual SW) in UP position, the current flowing toTERMINAL (A) 10 (Double cab), (B) 9 (Except double cab) of the power window master SW flows to TERMINAL (A) 1(Double cab), (B) 3 (Except double cab) to TERMINAL 1 of the power window motor LH to TERMINAL 2 to TERMINAL (A) 5(Double cab), (B) 4 (Except double cab) of the master SW to TERMINAL (A) 3 (Double cab), (B) 1 (Except double cab) toGROUND and causes the power window motor to rotate in the up direction. The window ascends only while the SW is beingpushed.In down operation, the current flowing from TERMINAL (A) 10 (Double cab), (B) 9 (Except double cab) of the power windowmaster SW to TERMINAL (A) 5 (Double cab), (B) 4 (Except double cab) flows to TERMINAL 2 of the motor LH to TERMINAL1 to TERMINAL (A) 1 (Double cab), (B) 3 (Except double cab) of the master SW to TERMINAL (A) 3 (Double cab), (B) 1(Except double cab) to GROUND, flowing in the opposite direction to manual up operation, causing the motor to rotate inreverse and lowering the window.

2. AUTO DOWN OPERATION (DRIVER’S WINDOW)With the ignition SW on and with the auto SW of the power window master SW in DOWN position, the current flowing toTERMINAL (A) 10 (Double cab), (B) 9 (Except double cab) of the master SW flows to TERMINAL (A) 5 (Double cab), (B) 4(Except double cab) of the master SW to TERMINAL 2 of the power window motor LH to TERMINAL 1 to TERMINAL (A) 1(Double cab), (B) 3 (Except double cab) of the master SW to TERMINAL (A) 3 (Double cab), (B) 1 (Except double cab) toGROUND, causing the motor to rotate towards the down side.Then the solenoid in the master SW is activated and it locks the auto SW being pushed, causing the motor to continue torotate in auto down operation.When the window has completely descended, the current flowing between TERMINAL (A) 1 (Double cab), (B) 3 (Exceptdouble cab) of the master SW and TERMINAL (A) 3 (Double cab), (B) 1 (Except double cab) increases. As a result, thesolenoid stops operating, the auto SW turns off and the flowing from TERMINAL (A) 10 (Double cab), (B) 9 (Except doublecab) of the master SW to TERMINAL (A) 5 (Double cab), (B) 4 (Except double cab) is cut off, stopping the motor so that autostop occurs.

3. STOPPING OF AUTO DOWN AT DRIVER’S WINDOWWhen the manual SW (Driver’s) is pushed to the up side during auto down operation, a ground circuit opens in the masterSW and current does not flow from TERMINAL (A) 1 (Double cab), (B) 3 (Except double cab) of the master SW toTERMINAL (A) 3 (Double cab), (B) 1 (Except double cab), so the motor stops, causing auto down operation to stop. If themanual SW is pushed continuously, the motor rotates in the up direction in manual up operation.

4. MANUAL OPERATION BY POWER WINDOW CONTROL SW (FRONT RH WINDOW)With the power window control SW front RH is pushed to the up side, the current flowing from TERMINAL 4 of the powerwindow control SW front RH flows to TERMINAL 3 to TERMINAL 2 of the power window motor front RH to TERMINAL 1 toTERMINAL 1 of the power window control SW front RH to TERMINAL 2 to TERMINAL (A) 6 (Double cab), (B) 10 (Exceptdouble cab) of the master SW to TERMINAL (A) 3 (Double cab), (B) 1 (Except double cab) to GROUND. This causes thepower window motor front RH to rotate in the up direction. Up operation is continuous only while the power window controlSW RH is pushed to the up side. When the window descends, the current flowing to the motor flows in the opposite direction,from TERMINAL 1 to TERMINAL 2, and the motor rotates in revers.When the window lock SW is pushed to the lock side, the ground circuit to the front RH window becomes open. As a result,even if Open/Close operation of the front RH window is tried, the current from TERMINAL (A) 3 (Double cab), (B) 1 (Exceptdouble cab) of the power window master SW is not grounded and the motor does not rotate, so the front RH window can notbe operated and window lock occurs.

5. MANUAL OPERATION (REAR LH, RH WINDOW) [DOUBLE CAB]With the power window control SW rear LH, RH pulled to the up side, the current flowing from TERMINAL 3 of the powerwindow control SW flows to TERMINAL 1 to TERMINAL 1 of the power window motor to TERMINAL 2 to TERMINAL 5 of thepower window control SW to TERMINAL 4 to TERMINAL (A) 12 (LH) or (A) 13 (RH) of the master SW to TERMINAL (A) 3(Double cab), (B) 1 (Except double cab) to GROUND and causes the power window motor rear LH, RH to rotate in the updirection. The up operation continues only while the power window control SW is pulled to the up side. When the windowdescends, the current flowing to the motor flows in the opposite direction, from TERMINAL 1 to TERMINAL 2, and the motorrotates in reverse. When the window lock SW is pushed to the lock side, the ground circuit to the rear LH, RH windowbecomes open.As a result, even if Open/Close operation of the rear LH, RH window is tried, the current from TERMINAL (A) 3 (Double cab),(B) 1 (Except double cab) of the power window master SW is not grounded and the motor does not rotate, so the rear LH,RH window can not be operated and window lock occurs.

6. KEY OFF POWER WINDOW OPERATIONWith the ignition SW turned from on to off, the body ECU operates for about 45 seconds and current flows from TERMINAL 1of the PWR relay to TERMINAL 2 to GROUND. For this period, current also flows TERMINAL 5 to TERMINAL 3. This currentflows to TERMINAL (A) 10 (Double cab), (B) 9 (Except double cab) of the power window master SW and to TERMINAL 4(Front RH), 3 (Rear) of the power window control SW. As a result, for about 45 seconds after the ignition SW is turned off, itis possible to raise and lower the power window by the functioning of the body ECU. Also, by opening the door (Doorcourtesy SW on) within about 45 seconds after turning the ignition SW to off, a signal is input to the dody ECU. As a result,the body ECU turns off, and up and down movement of the window stops.

Current always flows to TERMINAL 4 of the body ECU through the DOME fuse.

1. SEAT BELT WARNING SYSTEMWhen the ignition SW is turned on, current flows from the ECU-IG fuse to TERMINAL 10 of the body ECU. At the same time,current flows to the ECU from the GAUGE fuse through the seat belt warning light. This current activates the body ECU and,for approx. 4-8 seconds, the current flowing through the warning light flows from ECU to TERMINAL 8 to GROUND, causingthe warning light to light up. At the same time as the warning light lights up, a buckle SW LH on signal is input to the bodyECU, the current flowing from TERMINAL 4 of the body ECU flows to TERMINAL 8 to GROUND and the seat belt warningbuzzer sounds for approx. 4-8 seconds. However, if the seat belt is put on (Buckle SW LH off) during this period (While thebuzzer is sounding), a signal input to the body ECU stops and the current flowing from TERMINAL 4 of the body ECU toTERMINAL 8 to GROUND is cut, causing the buzzer to stop.

2. KEY REMINDER SYSTEMWith the ignition key inserted in the key cylinder (Unlock warning SW on), the ignition SW still off and front LH door open(Door courtesy SW on), a signal is input to the body ECU, the body ECU operates and current flows from TERMINAL 10 ofthe ECU to TERMINAL 8 to GROUND and the key reminder buzzer sounds.

AIR CONDITIONING

1. HEATER BLOWER MOTOR OPERATIONWith the ignition SW on, the current from the GAUGE fuse flows to TERMINAL 5 of the HEATER relay to TERMINAL 3 toTERMINAL 8 of the heater blower SW.(Low speed operation)When the heater blower SW is moved to the low speed position, the current applied to TERMINAL 8 of the heater blower SWflows from TERMINAL 1 to GROUND, causing the HEATER relay to come on. Then the current flowing from the HEATERfuse flows to TERMINAL 1 of the HEATER relay to TERMINAL 2 to TERMINAL 1 of the blower motor to TERMINAL 2 toTERMINAL 1 of the blower resistor to TERMINAL 4 to GROUND, causing the blower motor to rotate.At this time, current flows against the full resistance of the blower resistor, so the motor rotates slowly at low speed.(Operation at speed M1, M2)When the heater blower SW is moved to the speed M1 position, the current applied to TERMINAL 8 of the heater blower SWflows to TERMINAL 1 to GROUND, turning the HEATER relay to on. Then, the same as with low speed, current passes fromthe blower motor to TERMINAL 1 of the blower resistor to TERMINAL 2 to TERMINAL 6 of the heater blower SW toTERMINAL 1 to GROUND. At this time, the resistance of the blower resistor is less than it is for low speed, so the blowermotor rotates faster than it does at low speed. With the heater blower SW in the M2 position, current flowing through themotor flows from TERMINAL 1 of the blower resistor to TERMINAL 3 to TERMINAL 5 of the heater blower SW to TERMINAL1 to GROUND. At this time, the resistance of the blower resistor is less than for speed M1, so the blower motor rotates fasterthan for speed M1.(High speed operation)With the heater blower SW in high speed position, until the HEATER relay comes on and current flows to the blower motor,operation is the same as for speed M1 and M2. The current passing through the blower motor flows to TERMINAL 4 of theheater blower SW to TERMINAL 1 to GROUND without flowing through the blower resistor, so that the blower motor rotatesat the fastest speed, high speed.

2. AIR INLET CONTROL SERVO MOTOR OPERATION(Switching from FRESH to RECIRC)With the ignition SW turned on, the current flows from GAUGE fuse to TERMINAL 7 of the air inlet control servo motor toTERMINAL 3 to TERMINAL 6 of the A/C control assembly to TERMINAL 25 to GROUND, the motor rotates and the dampermoves to the RECIRC side. When the damper operates with the A/C SW at RECIRC position, the damper position signal isinput from TERMINAL 1 of the servo motor to TERMINAL 7 of the A/C control assembly. As a result, current to the servomotor circuit is cut off by the A/C control assembly, so the damper stops at that position.(Switching from RECIRC to FRESH)With the ignition SW turned on, when the RECIRC/FRESH SW is switched to the FRESH side, the current flows fromTERMINAL 7 of the air inlet control servo motor to TERMINAL 3 to TERMINAL 6 of the A/C control assembly to TERMINAL25 to GROUND, the motor rotates and the damper stops at that position.

3. AIR VENT MODE CONTROL SERVO MOTOR OPERATIONWhen the ignition SW turned on, the current flows from GAUGE fuse to TERMINAL 2 of the A/C control assembly.(Switching from DEF to FACE)The current flows from TERMINAL 17 of the A/C control assembly to TERMINAL 4 of the air vent mode control servo motorto TERMINAL 8 to TERMINAL 21 of the A/C control assembly to TERMINAL 25 to GROUND. The motor rotates and thedamper moves to the FACE side. When the damper operates with the A/C SW at FACE position, the damper position signalis input from TERMINAL 8 of the servo motor to the TERMINAL 21 of the A/C control assembly. As a result, current to theservo motor circuit is cut off by the A/C control assembly, so the damper stops at that position.(Switching from FACE to DEF)The current flows from TERMINAL 21 of the A/C control assembly to TERMINAL 8 of the air vent control servo motor toTERMINAL 4 to TERMINAL 17 of the A/C control assembly to TERMINAL 25 to GROUND, the motor rotates and thedamper stops at that position.

4. AIR MIX CONTROL SERVO MOTOR CONTROLWhen the temperature control SW is pressed, the A/C control assembly sends a signal to the air mix control servo motor.This signal drives the motor to reach the temperature set by the temperature control SW, and moves the film damper.

5. AIR CONDITIONING OPERATIONWhen the blower SW is set to on, current from the HEATER fuse flows through the HEATER relay (Point side) to A.C fuse toTERMINAL 2 of the A/C dual pressure SW to TERMINAL 1 to TERMINAL 3 of the A/C control assembly. The evaporatortemp. signal from the A/C thermistor are all supplied to the A/C control assembly. When the A/C SW is turned on, the A/CSW on signal is sent to activate the A/C control assembly. Current flows from the A/C control assembly to the magneticclutch, turning the compressor on. The A/C operation is shut off when a signal indicating low evaporator temp., or abnormallyhigh or low refrigerant pressure, is supplied while the engine high speed signal exists. When one of these signals isreceived, the assembly shuts off the A/C operation.
