HOW TO USE THIS MANUAL

This manual provides information on the electrical circuits in on vehicles by dividing them into a circuit for each system.

The actual wiring of each system circuit is shown from the point where the power source is received from the battery as far as each ground point. (All circuit diagrams are shown with the switches in the OFF position.)

When troubleshooting any problem, first understand the operation of the circuit where the problem was detected (see System Circuit section), the power source supplying power to that circuit (see Power Source section), and the ground points (see Ground Points section). See the System Outline to understand the circuit operation.

When the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing sections to find each part, junction block and wiring harness connectors, wiring harness and wiring harness connectors, splice points, and ground points of each system circuit. Internal wiring for each junction block is also provided for better understanding of connection within a junction block.

Wiring related to each system is indicated in each system circuit by arrows (from

, to ) . When overall connections are r equired, see the Overall Electrical Wiring

Diagram at the end of this manual.

HOW TO USE THIS MANUAL

The “Current Flow Chart” section, describes which parts each power source (fuses, fusible links, and circuit breakers) transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully understood.

POWER SOURCE (Current Flow Chart)

The chart below shows the route by which current flows from the battery to each electrical source (Fusible Link, Circuit Breaker, Fuse, etc.) and other parts.

The next page and following pages show the parts to which each electrical source outputs current.

POWER SOURCE

* The system shown here is an EXAMPLE ONLY. It is different to the actual circuit shown in the SYSTEM CIRCUITS SECTION.

The ground points circuit diagram shows the connections from all major parts to the respective ground points. When troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify the problem ground quickly. The relationship between ground points ( , , and shown below) can also be checked this way.

GROUND POINT

* The system shown here is an EXAMPLE ONLY. It is different to the actual circuit shown in the SYSTEM CIRCUITS SECTION.

TROUBLESHOOTING

VOLTAGE CHECK

(a) Establish conditions in which voltage is present at the

check point.

Example:

– Ignition SW on – Ignition SW and SW 1 on – Ignition SW, SW 1 and Relay on (SW 2 off)

(b) Using a voltmeter , connect the negative lead to a good

ground point or negative battery terminal, and the positive lead to the connector 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

voltage between the check points.

(b) Contact the two leads of an ohmmeter to each of the

check points.

If the circuit has diodes, reverse the two leads and check again.

When contacting the negative lead to the diode positive side and the positive lead to the negative side, there should be continuity.

When contacting the two leads in reverse, there should be no continuity.

minimum) 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:

– Ignition SW on – Ignition SW and SW 1 on – 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 the test light.

The short lies between the connector where the test

light stays lit and the connector where the light goes

out. (e) Find the exact location of the short by lightly shaking

the problem wire along the body.

CAUTION:

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.)

DISCONNECTION OF MALE AND FEMALE CONNECTORS

To pull apart the connectors, pull on the connector itself, not the wire harness.

HINT: Check to see what kind of connector you are disconnecting before pulling apart.

TROUBLESHOOTING

HOW TO REPLACE TERMINAL (Terminal Retainer Type)

1. DISCONNECT CONNECTOR

2. DISCONNECT TERMINAL FROM CONNECTOR (a) “for A type”

Raise the terminal retainer up to the temporary lock position.

HINT: The needle insertion position varies according to the connector ’s shape (number of terminals etc.), so check the position before inserting it.

”for B type” Open the terminal retainer.

(b) Release the locking lug from terminal and pull the

terminal out from rear.

3. INSTALL TERMINAL TO CONNECTOR (a) Insert the terminal. HINT:

1. Make sure the terminal is positioned correctly.

2. Insert the terminal until the locking lug locks firmly.

3. Insert the terminal with terminal retainer in the

temporary lock position.

(b) Push the terminal retainer in to the full lock position.

ENGINE CONTROL

SYSTEM OUTLINE

THE ENGINE CONTROL SYSTEM UTILIZES A MICROCOMPUTER AND MAINTAINS OVERALL CONTROL OF THE ENGINE, TRANSMISSION, ETC. AN OUTLINE OF ENGINE CONTROL IS GIVEN HERE.

1. INPUT SIGNALS

(1) WATER TEMP. SIGNAL SYSTEM

THE WATER TEMP. SENSOR DETECTS THE ENGINE COOLANT TEMP. AND HAS A BUILT–IN THERMISTOR WITH A RESISTANCE WHICH VARIES ACCORDING TO THE WATER TEMP. THUS THE WATER TEMP. IS INPUT IN THE FORM OF A CONTROL SIGNAL TO TERMINAL THW OF THE ENGINE AND ECT ECU.

(2) INTAKE AIR TEMP. SIGNAL SYSTEM

THE INTAKE AIR TEMP. SENSOR IS INSTALLED INSIDE THE AIR FLOW METER AND DETECTS THE INTAKE AIR TEMP., WHICH IS INPUT AS A CONTROL SIGNAL TO TERMINAL THA OF THE ECU.

(3) OXYGEN SENSOR SIGNAL SYSTEM

THE OXYGEN DENSITY IN THE EXHAUST EMISSIONS IS DETECTED AND INPUT AS A CONTROL SIGNAL TO TERMINAL OX1 OF THE ECU. TO MAINTAIN STABLE DETECTION PERFORMANCE BY THE OXYGEN SENSOR, A HEATER IS USED FOR WARMING THE SENSOR. THE HEATER IS ALSO CONTROLLED BY THE ECU (HT).

(4) RPM SIGNAL SYSTEM

CRANKSHAFT POSITION AND ENGINE RPM ARE DETECTED BY THE PICK–UP COIL INSTALLED INSIDE THE DISTRIBUTOR. CRANKSHAFT POSITION IS INPUT AS A CONTROL SIGNAL TO TERMINALS G1 AND G2, OF THE ECU, AND RPM IS INPUT TO TERMINAL NE.

(5) THROTTLE SIGNAL SYSTEM

THE THROTTLE POSITION SENSOR DETECTS THE THROTTLE VALVE OPENING ANGLE, WHICH IS INPUT AS A CONTROL SIGNAL TO TERMINAL VTA OF THE ECU, OR WHEN THE VALVE IS FULLY CLOSED, TO TERMINAL IDL.

(6) VEHICLE SPEED SIGNAL SYSTEM

THE SPEED SENSOR, INSTALLED INSIDE THE COMBINATION METER, DETECTS THE VEHICLE SPEED AND INPUTS A CONTROL SIGNAL TO TERMINAL SP1 OF THE ECU.

(7) NEUTRAL START SW SIGNAL SYSTEM (A/T)

THE NEUTRAL START SW DETECTS WHETHER THE SHIFT POSITION IS IN NEUTRAL OR NOT, AND INPUTS A CONTROL SIGNAL TO TERMINAL NSW OF THE ECU.

(8) A/C SW SIGNAL SYSTEM

THE OPERATING VOLTAGE OF THE A/C MAGNET CLUTCH IS DETECTED AND INPUT IN THE FORM OF A CONTROL SIGNAL TO TERMINAL A/C OF THE ECU.

(9) BATTER Y SIGNAL SYSTEM

VOLTAGE IS CONSTANTLY APPLIED TO TERMINAL BATT OF THE ECU. WHEN THE IGNITION SW IS TURNED TO ON, VOLTAGE FOR ECU OPERATION IS APPLIED VIA THE EFI MAIN RELAY TO TERMINALS +B AND +B1 OF THE ECU. ALSO, CURRENT FLOWS VIA THE IGN FUSE TO TERMINAL IGSW OF THE ECU.

(10) INTAKE AIR VOLUME SIGNAL SYSTEM

INTAKE AIR VOLUME IS DETECTED BY THE POTENTIOMETER INSTALLED INSIDE THE AIR FLOW METER AND IS INPUT AS A CONTROL SIGNAL TO TERMINAL VS OF THE ECU. INSIDE THE AIR FLOW METER THERE IS ALSO A SW FOR FUEL PUMP OPERATION, AND WHEN THE MEASURING PLATE OPENS (AIR INTAKE OCCURS), THIS SW TURNS ON AND CURRENT FLOWS TO THE FUEL PUMP TO OPERATE IT.

(11) STA SIGNAL SYSTEM

TO CONFIRM THAT THE ENGINE IS CRANKING, THE VOLTAGE APPLIED TO THE STARTER MOTOR DURING CRANKING IS DETECTED AND IS INPUT AS A CONTROL SIGNAL TO TERMINAL STA OF THE ECU.

(12) ENGINE KNOCK SIGNAL SYSTEM

ENGINE KNOCKING IS DETECTED BY THE KNOCK SENSOR AND INPUT AS A CONTROL SIGNAL TO TERMINAL KNK OF THE ECU.

2. CONTROL SYSTEM

* EFI (ELECTRONIC FUEL INJECTION) SYSTEM

THE EFI SYSTEM MONITORS THE ENGINE CONDITIONS THROUGH THE SIGNALS EACH SENSOR (INPUT SIGNALS (1 TO 11)) INPUTS TO THE ECU. BASED ON THIS DATA AND THE PROGRAM MEMORIZED IN THE ECU, THE MOST APPROPRIATE FUEL INJECTION TIMING IS DECIDED AND CURRENT IS OUTPUT TO TERMINALS #10, #20 AND #30 OF THE ECU. CAUSING THE INJECTORS TO OPERATE (TO INJECT FUEL). IT IS THIS SYSTEM WHICH, THROUGH THE WORK OF THE ECU, FINELY CONTROLS FUEL INJECTION IN RESPONSE TO DRIVING CONDITIONS.

* ESA (ELECTRONIC SPARK ADVANCE) SYSTEM

THE ESA SYSTEM MONITORS THE ENGINE CONDITIONS USING THE SIGNALS (INPUT SIGNALS (1, 3, 4, 5, 6, 8, 10, 11, 12)) INPUT TO THE ECU FROM EACH SENSOR. BASED ON THIS DATA AND THE PROGRAM MEMORIZED IN THE ECU, THE MOST APPROPRIATE IGNITION TIMING IS DECIDED AND CURRENT IS OUTPUT TO TERMINAL IGT OF THE ECU.

THIS OUTPUT CONTROLS THE IGNITER TO PRODUCE THE MOST APPROPRIATE IGNITION TIMING FOR THE DRIVING CONDITIONS.

* OXYGEN SENSOR HEATER CONTROL SYSTEM

THE OXYGEN SENSOR HEATER CONTROL SYSTEM TURNS THE HEATER TO ON WHEN THE INTAKE AIR VOLUME IS LOW (TEMP. OF EXHAUST EMISSIONS LOW), AND WARMS UP THE OXYGEN SENSOR TO IMPROVE DETECTION PERFORMANCE OF THE SENSOR. THE ECU EVALUATES THE SIGNALS FROM EACH SENSOR (INPUT SIGNALS (1, 4, 9, 10, 11)), CURRENT IS OUTPUT TO

TERMINAL HT AND CONTROLS THE HEATER.

* ISC (IDLE SPEED CONTROL) SYSTEM

THE ISC SYSTEM (STEP MOTOR TYPE) INCREASES THE RPM AND PROVIDES IDLING STABILITY FOR FAST IDLE–UP WHEN THE ENGINE IS COLD AND WHEN THE IDLE SPEED HAS DROPPED DUE TO ELECTRICAL LOAD, ETC. THE ECU EVALUATES THE SIGNALS FROM EACH SENSOR (INPUT SIGNALS (1, 4 TO 8, 11)), OUTPUTS CURRENT TO TERMINALS ISC1, ISC2, ISC3 AND ISC4, AND CONTROLS THE ISC VALVE.

* FUEL PRESSURE–UP SYSTEM

THE FUEL PRESSURE UP SYSTEM CAUSES THE VSV (FOR FUEL PRESSURE UP) TO COME ON FOR HIGH TEMP. STARTS AND IMMEDIATELY AFTER STARTING IN ORDER TO INCREASE THE FUEL PRESSURE, IMPROVE STARTABILITY AT HIGH TEMPERATURES AND PROVIDE STABLE IDLING. THE ECU EVALUATES THE INPUT SIGNALS FROM EACH SENSOR (1, 2, 4, AND 12), OUTPUTS CURRENT TO TERMINAL FPU AND CONTROLS THE VSV.

3. DIAGNOSIS SYSTEM

WITH THE DIAGNOSIS SYSTEM, WHEN THERE IS A MALFUNCTIONING IN THE ECU SIGNAL SYSTEM, THE MALFUNCTION SYSTEM IS RECORDED IN THE MEMORY. THE MALFUNCTION SYSTEM CAN THEN BE FOUND BY READING THE DISPLAY (CODE) OF THE CHECK ENGINE WARNING LIGHT.

4. FAIL–SAFE SYSTEM

WHEN A MALFUNCTION OCCURS IN ANY SYSTEM, IF THERE IS A POSSIBILITY OF ENGINE TROUBLE BEING CAUSED BY CONTINUED CONTROL BASED ON THE SIGNALS FROM THAT SYSTEM, THE FAIL–SAFE SYSTEM EITHER CONTROLS THE SYSTEM BY USING DATA (STANDARD VALUES) RECORDED IN THE ECU MEMORY OR ELSE ST OPS THE ENGINE.

WHEN THE ENGINE IS STARTED, VOLTAGE GENERATED AT TERMINAL L OF ALTERNATOR IS APPLIED TO TERMINAL 11 OF THE DAYTIME RUNNING LIGHT RELAY.

IF THE PARKING BRAKE LEVER IS PULLED UP (PARKING BRAKE SW ON) AT THIS TIME, THE RELAY IS NOT ENERGIZED, SO THE DAYTIME RUNNING LIGHT SYSTEM DOES NOT OPERATE. IF THE PARKING BRAKE LEVER IS THEN RELEASED (PARKING BRAKE SW OFF), THE SIGNAL IS INPUT TO TERMINAL 8 OF THE RELAY. THIS ACTIVATES THE RELAY AND CURRENT FROM MAIN FUSE FLOWS TO TAILLIGHT RELAY (POINT SIDE) → TAIL FUSE → TAIL, LICENCE AND FRONT CLEARANCE LIGHTS → GROUND. ALSO, CURRENT FROM FL ALT FLOWS TO HEADLIGHT RELAY (POINT SIDE) → DIMMER RELAY (POINT SIDE) → HEAD LOW FUSES → HEADLIGHTS (LOW SIDE) → TO GROUND, SO BOTH TAIL AND HEAD LIGHTS LIGHT UP.

THIS IS HOW THE DAYTIME RUNNING LIGHT SYSTEM OPERATES. ONCE THE DAYTIME RUNNING LIGHT SYSTEM OPERATES AND TAIL, HEAD LIGHT HAVE LIGHTED UP, THE TAIL AND HEAD LIGHTS

REMAIN ON EVEN IF THE PARKING BRAKE LEVER IS PULLED UP (PARKING BRAKE SW ON). EVEN IF THE ENGINE STALLS WITH THE IGNITION SW ON AND THERE IS NO VOLTAGE FROM TERMINAL L OF ALTERNATOR, THE

TAIL AND HEAD LIGHTS REMAIN ON. IF THE IGNITION SW IS THEN TURNED OFF, TAIL AND HEAD LIGHTS ARE TURNED OFF. IF THE ENGINE IS STARTED WHILE THE PARKING BRAKE IS RELEASED (PARKING BRAKE SW OFF), THE DAYTIME RUNNING LIGHT

SYSTEM OPERATES AND THE TAIL AND HEAD LIGHTS LIGHT UP AS THE ENGINE STARTS.

WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS TO TERMINAL 6 OF THE INTEGRATION RELAY THROUGH GAUGE FUSE.

VOLTAGE IS APPLIED AT ALL TIMES TO TERMINAL (A) 2 OF THE INTEGRATION RELAY THROUGH THE TAILLIGHT RELAY (COIL SIDE), AND TO TERMINAL (A) 3 THROUGH THE HEADLIGHT RELA Y (COIL SIDE).

1. NORMAL LIGHTING OPERATION

(TURN TAILLIGHT ON) WITH LIGHT CONTROL SW TURNED TO TAILLIGHT POSITION, A SIGNAL IS INPUT INTO TERMINAL (A) 1 OF THE INTEGRATION

RELAY. ACCORDING TO THIS SIGNAL, THE CURRENT FLOWING TO TERMINAL (A) 2 OF THE RELA Y FLOWS FROM TERMINAL (A) 1 → TERMINAL 2 OF THE LIGHT CONTROL SW → TERMINAL 11 → TO GROUND AND TAILLIGHT RELAY CAUSES TAILLIGHT TO TURN ON.

(TURN HEADLIGHT ON) WITH LIGHT CONTROL SW TURNED TO HEADLIGHT POSITION, A SIGNAL IS INPUT INTO TERMINALS (A) 1 AND (A) 4 OF THE

INTEGRATION RELAY. ACCORDING TO THIS SIGNAL, THE CURRENT FLOWING TO TERMINAL (A) 3 OF THE RELAY FLOWS TO TERMINAL (A) 4 → TERMINAL 13 OF THE LIGHT CONTROL SW → TERMINAL 11 → TO GROUND IN THE HEADLIGHT CIRCUIT, AND CAUSES T AILLIGHT AND HEADLIGHT RELAY TO TURN THE LIGHT ON. THE TAILLIGHT CIRCUIT IS SAME AS ABOVE.

2. LIGHT AUTO TURN OFF OPERATION

WITH LIGHTS ON AND IGNITION SW TURNED OFF (INPUT SIGNAL GOES TO TERMINAL 6 OF THE RELA Y), WHEN DOOR ON DRIVER’S SIDE IS OPENED (INPUT SIGNAL GOES TO TERMINAL 7 OF THE RELAY), THE RELAY OPERATES AND THE CURRENT IS CUT OFF WHICH FLOWS FROM TERMINAL (A) 2 OF THE RELAY TO TERMINAL (A) 1 IN TAILLIGHT CIRCUIT AND FROM TERMINAL (A) 3 TO

TERMINAL (A) 4 IN HEADLIGHT CIRCUIT. AS A RESULT, ALL LIGHTS ARE TURNED OFF AUTOMATICALLY.

WIPER MOTOR

SYSTEM OUTLINE

WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS TO TERMINAL 18 OF THE WIPER AND WASHER SW, TERMINAL 2 OF THE WASHER MOTOR AND TERMINAL 4 OF THE WIPER MOTOR THROUGH THE WIPER FUSE.

1. LOW SPEED POSITION

WITH WIPER SW TURNED TO LOW POSITION, THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW → TERMINAL 7 → TERMINAL 2 OF THE WIPER MOTOR → WIPER MOTOR → TO GROUND AND CAUSES THE WIPER MOTOR TO RUN AT

LOW SPEED.

2. HIGH SPEED POSITION

WITH WIPER SW TURNED TO HIGH POSITION, THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW → TERMINAL 13 → TERMINAL 1 OF THE WIPER MOTOR → WIPER MOTOR → TO GROUND AND CAUSES THE WIPER MOTOR TO RUN

AT HIGH SPEED.

3. INT POSITION (W/ INT SW)

WITH WIPER SW TURNED TO INT POSITION, THE RELAY OPERATES AND THE CURRENT WHICH IS CONNECTED BY RELAY FUNCTION FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW → TERMINAL 16 → TO GROUND. THIS FLOW OF CURRENT OPERATES THE INTERMITTENT CIRCUIT AND THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW → TERMINAL 7 → TERMINAL 2 OF THE WIPER MOTOR → TO GROUND AND THE WIPER FUNCTIONS.

THE INTERMITTENT OPERATION IS CONTROLLED BY A CONDENSER’S CHARGED AND DISCHARGED FUNCTION INSTALLED IN RELAY AND THE INTERMITTENT TIME IS CONTROLLED BY A TIME CONTROL SW TO CHANGE THE CHARGING TIME OF THE CONDENSER.

4. WASHER CONTINUOUS OPERATION (W/ INT CONTROL)

WITH WASHER SW TURNED TO ON, THE CURRENT FLOWS FROM TERMINAL 2 OF THE WASHER MOTOR → TERMINAL 1 → TERMINAL 8 OF THE WIPER AND WASHER SW → TERMINAL 16 → TO GROUND AND CAUSES THE WASHER MOTOR TO RUN AND

WINDOW WASHER TO JET. THIS CAUSES THE CURRENT TO FLOW TO WASHER CONTINUOUS OPERATION CIRCUIT (W/ INT SW) IN TERMINAL 18 OF THE WIPER AND WASHER SW → TERMINAL 7 → TERMINAL 2 OF THE WIPER MOTOR → TO GROUND AND THE WIPER FUNCTION.

SYSTEM OUTLINE

WITH THE IGNITION SW TURNED ON, CURRENT FLOWS TO POWER MAIN RELAY (COLD SIDE) THROUGH THE GAUGE FUSE. AS A RESULT, THE POWER MAIN RELAY TURNS ON AND THE CURRENT FLOWS FROM THE POWER CB TO POWER MAIN RELAY

(POINT SIDE) → TERMINAL 6 OF THE MOON ROOF CONTROL RELA Y.

1. SLIDE OPEN OPERATION

WITH THE IGNITION SW TURNED ON AND THE MOON ROOF SW PUSHED TO OPEN POSITION, THE CURRENT FLOWING TO TERMINAL 6 OF MOON ROOF CONTROL RELAY FLOWS THROUGH TERMINAL 12 TO GROUND.

AS A RESULT, THE RELAY COIL OPERATES AND THE CURRENT FLOWS FROM TERMINAL 6 OF RELAY → TERMINAL 5 → TERMINAL 2 OF MOON ROOF MOTOR → MOTOR → TERMINAL 1 → TERMINAL 1 OF RELAY → TERMINAL 12 → TO GROUND AND ROTATES THE MOTOR TO OPEN THE MOON ROOF AS LONG AS THE MOON ROOF SW IS PUSHED.

WHEN THE MOON ROOF IS OPENED COMPLETELY, EVEN IF THE MOON ROOF SW IS PUSHED CONTINUOUSLY, THE CURRENT TO THE MOON ROOF INCREASES.

IN THIS CASE, THE CIRCUIT BREAKER BUILT INTO THE MOTOR OPENS AND CUTS OUT THE CURRENT TO THE MOTOR, PREVENTING THE MOTOR FROM BURNING OUT.

2. SLIDE CLOSE OPERATION

WITH THE IGNITION SWITCH TURNED ON AND THE MOON ROOF SW PUSHED TO CLOSE POSITION, A SIGNAL IS INPUT TO TERMINAL 7 OF MOON ROOF CONTROL RELAY FROM TERMINAL 6 OF THE MOON ROOF SW. THUS THE RELAY COIL OPERATES

AND THE CURRENT FLOWING TO TERMINAL 6 OF RELAY FLOWS TO TERMINAL 1 → TERMINAL 1 OF MOON ROOF MOTOR → MOTOR → TERMINAL 2 → TERMINAL 5 OF RELAY → TERMINAL 12 → TO GROUND AND ROTATES THE MOTOR TO CLOSE THE MOON ROOF. SLIDE CLOSE OPERA TION CONTINUES WHILE THE MOON ROOF SWITCH CONTINUES TO BE PUSHED. 100MM (3.94IN.) BEFORE THE FULLY CLOSED POSITION THE MOON ROOF LIMIT SW TURNS OFF AND THIS SIGNAL IS INPUT INTO THE RELAY, SO THE RELAY STOPS OPERATION. THUS CURRENT DOES NOT FLOW TO THE MOON ROOF MOTOR AND THE MOON ROOF AUTOMATICALLY ST OPS.

IF THE MOON ROOF SW IS THEN PUSH AGAIN, THE TIMER INSTALLED IN THE MOON ROOF CONTROL TURNS ON AND THE RELAY OPERATES FOR APPROX. 0.65SEC. TO RE–OPERATE THE MOTOR SO THAT THE MOON ROOF LIMIT SW TURNS ON. AS A RESULT, AS LONG AS THE MOON ROOF SW IS PUSHED, SLIDE CLOSE OPERATION OCCURS AND THE MOON ROOF IS ABLE TO FULLY CLOSE.

SYSTEM OUTLINE

WITH THE IGNITION SW TURNED ON, CURRENT FLOWS THROUGH THE GAUGE FUSE → TERMINAL 1 OF THE POWER MAIN RELAY → TERMINAL 3 → TO GROUND. THIS ACTIVATES THE RELAY AND THE CURRENT FLOWING TO TERMINAL 2 OF THE RELAY FROM

POWER CB FLOWS TO TERMINAL 4 OF THE RELAY → TERMINAL 9 OF THE POWER WINDOW MASTER SW, TERMINAL 5 (PASSENGER’S) AND TERMINAL 3 (REAR LH, RH) OF THE POWER WINDOW SW.

1. MANUAL OPERATION (DRIVER’S WINDOW)

WITH THE IGNITION SW TURNED ON AND WITH THE POWER WINDOW MASTER SW (MASTER SW) IN UP POSITION, THE CURRENT FLOWING TO TERMINAL 9 OF THE POWER WINDOW MASTER SW FLOWS TO TERMINAL 4 OF THE MASTER SW → TERMINAL 1 OF THE POWER WINDOW MOTOR → TERMINAL 2 → TERMINAL 10 OF THE MASTER SW → TERMINAL 8 → TO GROUND AND CAUSES THE POWER WINDOW MOTOR TO ROTATE IN THE UP DIRECTION. THE WINDOW ASCENDS ONLY WHILE THE SW IS BEING PUSHED. IN DOWN OPERATION, THE FLOW OF CURRENT FROM TERMINAL 9 OF THE POWER WINDOW MASTER SW TO TERMINAL 10 OF THE MASTER SW CAUSES THE FLOW OF CURRENT FROM TERMINAL 2 OF THE MOTOR → TERMINAL 1 → TERMINAL 4 OF THE MASTER SW → TERMINAL 8 → TO GROUND, FLOWING IN THE OPPOSITE DIRECTION TO MANUAL UP OPERATION AND CAUSING THE MOTOR TO ROTATE IN REVERSE, LOWERING THE WINDOW.

2. AUTO DOWN OPERATION

WITH THE IGNITION SW ON AND WITH THE AUTO SW OF THE POWER WINDOW MASTER SW IN DOWN POSITION, CURRENT FLOWING TO TERMINAL 9 OF THE MASTER SW FLOWS TO TERMINAL 10 OF THE MASTER SW → TERMINAL 2 OF THE POWER WINDOW MOTOR → TERMINAL 1 → TERMINAL 4 OF THE MASTER SW → TERMINAL 8 → TO GROUND, 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 TO ROTATE IN THE AUTO DOWN OPERATION. WHEN THE WINDOW HAS COMPLETELY DESCENDED, THE CURRENT FLOW BETWEEN TERMINAL 4 OF THE MASTER SW AND TERMINAL 8 INCREASES. AS A RESULT, THE SOLENOID STOPS OPERATING, THE AUTO SW TURNS OFF AND FLOW FROM TERMINAL 9 OF THE MASTER SW TO

TERMINAL 10 IS CUT OFF, STOPPING THE MOTOR SO THAT AUTO STOP OCCURS.

3. STOPPING OF AUTO DOWN AT DRIVER’S WINDOW

WHEN THE MASTER SW (DRIVER’S) IS PULLED TO THE UP SIDE DURING AUTO DOWN OPERATION, A GROUND CIRCUIT OPENS IN THE MASTER SW AND CURRENT DOES NOT FLOW FROM TERMINAL 4 OF THE MASTER SW → TO TERMINAL 8, SO THE MOTOR STOPS, CAUSING AUT O DOWN OPERATION TO STOP. IF THE MASTER SW IS PULLED CONTINUOUSLY, THE MOTOR ROTATES IN THE UP DIRECTION IN MANUAL UP OPERATION.

4. MANUAL OPERATION BY POWER WINDOW SW (PASSENGER’S WINDOW)

WITH POWER WINDOW SW (PASSENGER’S) PULLED TO THE UP SIDE, CURRENT FLOWING FROM TERMINAL 5 OF THE POWER WINDOW SW FLOWS TO TERMINAL 2 OF THE POWER WINDOW SW → TERMINAL 1 OF THE POWER WINDOW MOTOR → TERMINAL 2 → TERMINAL 3 OF THE POWER WINDOW SW → TERMINAL 1 → TERMINAL 3 OF THE MASTER SW → TERMINAL 8 → TO GROUND AND CAUSES THE POWER WINDOW MOTOR (PASSENGER’S) TO ROTATE IN THE UP DIRECTION. UP OPERATION CONTINUES ONLY WHILE THE POWER WINDOW SW IS PULLED 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 REVERSE. WHEN THE WINDOW LOCK SW IS PUSHED TO THE LOCK SIDE, THE GROUND CIRCUIT TO THE PASSENGER’S WINDOW BECOMES OPEN. AS A RESULT, EVEN IF OPEN/CLOSE OPERATION OF THE PASSENGER’S WINDOW IS TRIED, THE CURRENT FROM TERMINAL 8 OF THE POWER WINDOW MASTER SW IS NOT GROUNDED AND THE MOTOR DOES NOT ROTATE, SO THE PASSENGER’S WINDOW CAN NOT BE OPERATED AND WINDOW LOCK OCCURS. FURTHERMORE REAR LH, RH WINDOW OPERATE THE SAME AS THE ABOVE CIRCUIT.

SRS AIRBAG

NOTICE: When inspecting or repairing the SRS AIRBAG, perform the operation in accordance with the following precautionary instructions and the procedure and precautions in the Repair Manual for the applicable model year.

 Malfunction symptoms of the airbag system are difficult to confirm, so the diagnostic codes become the most

important source of information when troubleshooting. When troubleshooting the airbag system, always inspect the diagnostic codes before disconnecting the

battery.

 Work must be started after 20 seconds or longer from the time the Ignition SW is set to the “LOCK” position

and the negative (–) terminal cable is disconnected from the battery. (The airbag system is equipped with a back–up power source so that if work is started within 20 seconds of

disconnecting the negative (–) terminal cable of the battery, the airbag may be deployed.) When the negative (–) terminal cable is disconnected from the battery, memory of the clock and audio systems

will be cancelled. So before starting work, make a record of the contents memorized by each memory system. Then when work is finished, reset the clock and audio system as before.

To avoid erasing the memory of each memory system, never use a back–up power supply from outside the vehicle.

 When removing the steering wheel pad or handling a new steering wheel pad, keep the pad upper surface

facing upward. Also, lock the lock lever of the twin lock type connector at the rear of the pad and take care not to damage the connector.

(Storing the pad with its metallic surface up may lead to a serious accident if the airbag inflates for some reason.)

 Store the steering wheel pad where the ambient temperature remains below 93°C (200°F), without high

humidity and away from electrical noise.

 Never use airbag parts from another vehicle. When replacing airbag parts, replace them with new parts.  Never disassemble or repair the steering wheel pad, center airbag sensor assembly or front airbag sensors.  Before repairing the body, remove the airbag sensors if during repair shocks are likely to be applied to the

sensors due to vibration of the body or direct tapping with tools or other parts.

 Do not reuse a steering wheel pad or front airbag sensors.

After evaluating whether the center airbag sensor assembly is damaged or not, decide whether or not to reuse it. (See the Repair Manual for the method for evaluating the center airbag sensor assembly.)

 When troubleshooting the airbag system, use a high–impedance (Min. 10k/V) tester.  The wire harness of the airbag system is combined with the engine room main wiring harness assembly and

cowl wiring harness assembly. The vehicle wiring harness exclusively for the airbag system is distinguished by corrugated yellow tubing, as

are the connectors.

 Do not measure the resistance of the airbag squib.

(It is possible this will deploy the airbag and is very dangerous.)

 If the wire harness used in the airbag system is damaged, replace the whole wire harness assembly.

When the connector to the airbag front sensors can be repaired alone (when there is no damage to the wire harness), use the repair wire specially designed for the purpose.

(Refer to the Repair Manual for the applicable Model year for details of the replacement method.)

 INFORMATION LABELS (NOTICES) are attached to the periphery of the airbag components. Follow the

instructions on the notices.
