HOW TO USE THIS MANUAL

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 power sourceis received from the battery as far as each ground point. (All circuit diagrams are shownwith the switches in the OFF position.)

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

When the circuit operation is understood, begin troubleshooting of the problem circuitto isolate the cause. Use Relay Location and Electrical Wire Routing sections to findeach part, junction block and wiring harness connectors, wiring harness and wiringharness connectors, splice points, and ground points of each system circuit. Internalwiring for each junction block is also provided for better understanding of connectionwithin 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 Wiring Diagramat the end of this manual.

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

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 areexplained. Since all System Circuit diagrams start from the power source, the power source system must be fully understood.

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

GROUND POINTS

9

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

10

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 goodground point or negative battery terminal, and thepositive lead to the connector or component terminal.This check can be done with a test light instead of avoltmeter.

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 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.

11

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 testlight stays lit and the connector where the light goesout.

(e) Find the exact location of the short by lightly shakingthe problem wire along the body.

CAUTION:(a) Do not open the cover or the case of the ECU unless

absolutely necessary. (If the IC terminals aretouched, the IC may be destroyed by staticelectricity.)

(b) When replacing the internal mechanism (ECU part)of the digital meter, be careful that no part of yourbody or clothing comes in contact with theterminals of leads from the IC, etc. of thereplacement part (spare part).

DISCONNECTION OF MALE AND FEMALECONNECTORSTo pull apart the connectors, pull on the connector itself, not thewire harness.HINT: Check to see what kind of connector you are disconnectingbefore pulling apart.

2. CONTROL SYSTEM

* SEQUENTIAL MULTIPORT FUEL INJECTION (ELECTRONIC FUEL INJECTION) SYSTEM

THE SEQUENTIAL MULTIPORT FUEL INJECTION (ELECTRONIC FUEL INJECTION) SYSTEM MONITORS THE ENGINE CONDITIONTHROUGH THE SIGNALS INPUT FROM EACH SENSOR (INPUT SIGNALS FROM (1) TO (13) ETC.) TO THE ENGINE CONTROLMODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU). THE BEST FUEL INJECTION TIMING IS DECIDEDBASED ON THIS DATA AND THE PROGRAM MEMORIZED BY THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLYCONTROLLED TRANSMISSION ECU), AND THE CONTROL SIGNAL IS OUTPUT TO TERMINALS #10, #20, #30, 40, #50 AND #60 OFTHE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) TO OPERATE THEINJECTOR (INJECT THE FUEL). THE SEQUENTIAL MULTIPORT FUEL INJECTION (ELECTRONIC FUEL INJECTION) SYSTEMPRODUCES CONTROLS OF FUEL INJECTION OPERATION BY THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLYCONTROLLED TRANSMISSION ECU) IN RESPONSE TO THE DRIVING CONDITIONS.

* ESA (ELECTRONIC SPARK ADVANCE) SYSTEM

THE ESA SYSTEM MONITORS THE ENGINE CONDITION THROUGH THE SIGNALS INPUT TO THE ENGINE CONTROL MODULE(ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) FROM EACH SENSOR (INPUT SIGNALS FROM (1), (2), (4) TO(13) ETC.). THE BEST IGNITION TIMING IS DECIDED ACCORDING TO THIS DATA AND THE MEMORIZED DATA IN THE ENGINECONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) AND THE CONTROL SIGNAL IS OUTPUTTO TERMINALS IGT1 , IGT2, IGT3, IGT4, IGT5 AND IGT6 THESE SIGNALS CONTROL THE IGNITER TO PROVIDE THE BEST IGNITIONTIMING FOR THE DRIVING CONDITIONS.

* HEATED OXYGEN SENSOR HEATER CONTROL SYSTEM

THE MAIN HEATED OXYGEN SENSOR, SUB HEATED OXYGEN SENSOR HEATER CONTROL SYSTEM TURNS THE HEATER ONWHEN THE INTAKE AIR VOLUME IS LOW (TEMP. OF EXHAUST EMISSIONS IS LOW), AND WARMS UP THE OXYGEN SENSOR TOIMPROVE DETECTION PERFORMANCE OF THE SENSOR. THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLYCONTROLLED TRANSMISSION ECU) EVALUATES THE SIGNALS FROM EACH SENSOR (INPUT SIGNALS FROM (1), (2), (4), (9) TO(11) ETC.), AND OUTPUTS CURRENT TO TERMINALS HT1 , HT2 TO CONTROL THE HEATER.

* IDLE AIR CONTROL (IDLE SPEED CONTROL) SYSTEM

THE IDLE AIR CONTROL (ISC) SYSTEM (STEP MOTOR TYPE) INCREASES THE ENGINE SPEED AND PROVIDES IDLING STABILITYFOR FAST IDLE–UP WHEN THE ENGINE IS COLD, AND WHEN THE IDLE SPEED HAS DROPPED DUE TO ELECTRICAL LOAD AND SOON. THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) EVALUATE THESIGNALS FROM EACH SENSOR (INPUT SIGNALS FROM (1), (4), (5), (8), (9), (11) ETC.), OUTPUTS CURRENT TO TERMINALS ISC1,ISC2, ISC3 AND ISC4 TO CONTROL THE IDLE AIR CONTROL VALVE (ISC VALVE).

* EGR CONTROL SYSTEM

THE EGR CONTROL SYSTEM DETECTS THE SIGNAL FROM EACH SENSOR (INPUT SIGNALS FROM (1), (4), (9), (10) ETC.), ANDOUTPUTS CURRENT TO TERMINAL EGR TO CONTROL THE EGR VALVE.

* FUEL PUMP CONTROL SYSTEM

THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) OUTPUTS CURRENT TOTERMINAL FPC AND CONTROLS THE FUEL PUMP ECU AND FUEL PUMP DRIVE SPEED IN RESPONSE TO THE DRIVINGCONDITIONS.

3. DIAGNOSIS SYSTEMWITH THE DIAGNOSIS SYSTEM, WHEN THERE IS A MALFUNCTION IN THE ENGINE CONTROL MODULE (ENGINE ANDELECTRONICALLY CONTROLLED TRANSMISSION ECU) SIGNAL SYSTEM, THE MALFUNCTIONING SYSTEM IS RECORDED IN THEMEMORY. THE MALFUNCTIONING SYSTEM CAN BE FOUND BY READING THE CODE DISPLAYED BY THE MALFUNCTION INDICATORLAMP (CHECK ENGINE WARNING LIGHT).

4. FAIL–SAFE SYSTEMWHEN A MALFUNCTION HAS OCCURRED IN ANY SYSTEM, IF THERE IS A POSSIBILITY OF ENGINE TROUBLE BEING CAUSED BYCONTINUED CONTROL BASED ON THE SIGNALS FROM THAT SYSTEM, THE FAIL–SAFE SYSTEM EITHER CONTROLS THE SYSTEMBY USING DATA (STANDARD VALUES) RECORDED IN THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLYCONTROLLED TRANSMISSION ECU) MEMORY OR ELSE STOPS THE ENGINE.

2. CONTROL SYSTEM

* SEQUENTIAL MULTIPORT FUEL INJECTION (ELECTRONIC FUEL INJECTION) SYSTEM

THE SEQUENTIAL MULTIPORT FUEL INJECTION (ELECTRONIC FUEL INJECTION) SYSTEM MONITORS THE ENGINE CONDITIONTHROUGH THE SIGNALS INPUT FROM EACH SENSOR (INPUT SIGNALS FROM (1) TO (13) ETC.) TO THE ENGINE CONTROLMODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU). THE BEST FUEL INJECTION TIMING IS DECIDEDBASED ON THIS DATA AND THE PROGRAM MEMORIZED BY THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLYCONTROLLED TRANSMISSION ECU), AND THE CONTROL SIGNAL IS OUTPUT TO TERMINALS #10, #20, #30, 40, #50 AND #60 OFTHE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) TO OPERATE THEINJECTOR (INJECT THE FUEL). THE SEQUENTIAL MULTIPORT FUEL INJECTION (ELECTRONIC FUEL INJECTION) SYSTEMPRODUCES CONTROLS OF FUEL INJECTION OPERATION BY THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLYCONTROLLED TRANSMISSION ECU) IN RESPONSE TO THE DRIVING CONDITIONS.

* ESA (ELECTRONIC SPARK ADVANCE) SYSTEM

THE ESA SYSTEM MONITORS THE ENGINE CONDITION THROUGH THE SIGNALS INPUT TO THE ENGINE CONTROL MODULE(ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) FROM EACH SENSOR (INPUT SIGNALS FROM (1), (2), (4) TO(13) ETC.). THE BEST IGNITION TIMING IS DECIDED ACCORDING TO THIS DATA AND THE MEMORIZED DATA IN THE ENGINECONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) AND THE CONTROL SIGNAL IS OUTPUTTO TERMINAL IGT. THIS SIGNAL CONTROLS THE IGNITER TO PROVIDE THE BEST IGNITION TIMING FOR THE DRIVINGCONDITIONS.

* HEATED OXYGEN SENSOR HEATER CONTROL SYSTEM (FOR CALIFORNIA)

THE MAIN HEATED OXYGEN SENSOR FRONT AND REAR SIDE, SUB HEATED OXYGEN SENSOR HEATER CONTROL SYSTEMTURNS THE HEATER ON WHEN THE INTAKE AIR VOLUME IS LOW (TEMP. OF EXHAUST EMISSIONS IS LOW), AND WARMS UP THEOXYGEN SENSOR TO IMPROVE DETECTION PERFORMANCE OF THE SENSOR. THE ENGINE CONTROL MODULE (ENGINE ANDELECTRONICALLY CONTROLLED TRANSMISSION ECU) EVALUATES THE SIGNALS FROM EACH SENSOR (INPUT SIGNALS FROM(1), (2), (4), (9) TO (11) ETC.), AND OUTPUTS CURRENT TO TERMINALS HT1 , HT2, HT3 TO CONTROL THE HEATER.

* IDLE AIR CONTROL (IDLE SPEED CONTROL) SYSTEM

THE IDLE AIR CONTROL (ISC) SYSTEM (STEP MOTOR TYPE) INCREASES THE ENGINE SPEED AND PROVIDES IDLING STABILITYFOR FAST IDLE–UP WHEN THE ENGINE IS COLD, AND WHEN THE IDLE SPEED HAS DROPPED DUE TO ELECTRICAL LOAD AND SOON. THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) EVALUATES THESIGNALS FROM EACH SENSOR (INPUT SIGNALS FROM (1), (4), (5), (8), (9), (11) ETC.), OUTPUTS CURRENT TO TERMINALS ISC1,ISC2, ISC3 AND ISC4 TO CONTROL THE IDLE AIR CONTROL VALVE (ISC VALVE).

* EGR CONTROL SYSTEM

THE EGR CONTROL SYSTEM DETECTS THE SIGNAL FROM EACH SENSOR (INPUT SIGNALS FROM (1), (4), (9), (10) ETC.), ANDOUTPUTS CURRENT TO TERMINAL EGR TO CONTROL THE EGR VALVE.

* FUEL PUMP CONTROL SYSTEM

THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) OUTPUTS CURRENT TOTERMINAL FPC AND CONTROLS THE FUEL PUMP ECU AND FUEL PUMP DRIVE SPEED IN RESPONSE TO THE DRIVINGCONDITIONS.

* ACIS (ACOUSTIC CONTROL INDUCTION SYSTEM)

ACIS INCLUDES A VALVE IN THE BULKHEAD SEPARATING THE SURGE TANK INTO TWO PARTS. THIS VALVE IS OPENED ANDCLOSED IN ACCORDANCE WITH THE DRIVING CONDITIONS TO CONTROL THE INTAKE MANIFOLD LENGTH IN TWO STAGES FORINCREASED ENGINE OUTPUT IN ALL RANGES FROM LOW TO HIGH SPEEDS.

THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) JUDGES THE VEHICLESPEED BY THE SIGNALS ((4), (5)) FROM EACH SENSOR AND OUTPUTS SIGNALS TO THE TERMINAL ACIS TO CONTROL THE VSV(FOR INTAKE CONTROL VALVE).

3. DIAGNOSIS SYSTEMWITH THE DIAGNOSIS SYSTEM, WHEN THERE IS A MALFUNCTION IN THE ENGINE CONTROL MODULE (ENGINE ANDELECTRONICALLY CONTROLLED TRANSMISSION ECU) SIGNAL SYSTEM, THE MALFUNCTIONING SYSTEM IS RECORDED IN THEMEMORY. THE MALFUNCTIONING SYSTEM CAN BE FOUND BY READING THE CODE DISPLAYED BY THE MALFUNCTION INDICATORLAMP (CHECK ENGINE WARNING LIGHT).

4. FAIL–SAFE SYSTEMWHEN A MALFUNCTION HAS OCCURRED IN ANY SYSTEM, IF THERE IS A POSSIBILITY OF ENGINE TROUBLE BEING CAUSED BYCONTINUED CONTROL BASED ON THE SIGNALS FROM THAT SYSTEM, THE FAIL–SAFE SYSTEM EITHER CONTROLS THE SYSTEMBY USING DATA (STANDARD VALUES) RECORDED IN THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLYCONTROLLED TRANSMISSION ECU) MEMORY OR ELSE STOPS THE ENGINE.

VOLTAGE IS ALWAYS APPLIED FROM THE MAIN FUSE, THROUGH THE HEADLIGHT RELAY (COIL SIDE) TO TERMINAL 5 OF THEDAYTIME RUNNING LIGHT RELAY (MAIN), TERMINAL 6 OF INTEGRATION RELAY, TERMINAL 14 OF DIMMER SW, DIMMER RELAY(DAYTIME RUNNING LIGHT RELAY NO. 2) (COIL SIDE), TO TERMINAL 17 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN). WHEN THEIGNITION SW IS TURNED ON, VOLTAGE FROM THE GAUGE FUSE IS APPLIED TO TERMINAL 2 OF THE DAYTIME RUNNING LIGHTRELAY (MAIN).

1. DAYTIME RUNNING LIGHT OPERATIONWHEN THE ENGINE STARTS, VOLTAGE FROM TERMINAL “L” OF THE GENERATOR (ALTERNATOR) IS APPLIED TO TERMINAL 11 OFTHE DAYTIME RUNNING LIGHT RELAY (MAIN). IF THE PARKING BRAKE LEVER IS PULLED UP (PARKING BRAKE SW ON) AT THISTIME, THE DAYTIME RUNNING LIGHT SYSTEM DOES NOT OPERATE. WHEN THE PARKING BRAKE IS RELEASED (PARKING BRAKESW OFF), A SIGNAL IS OUTPUT FROM TERMINAL 1 OF THE PARKING BRAKE SW TO TERMINAL 8 OF THE DAYTIME RUNNING LIGHTRELAY (MAIN). THIS ACTIVATES THE DAYTIME RUNNING LIGHT RELAY (MAIN), TURNING ON THE DIMMER RELAY (DAYTIMERUNNING LIGHT RELAY NO. 2). CURRENT ALSO FLOWS FROM THE MAIN FUSE TO DIMMER RELAY (DAYTIME RUNNING LIGHTRELAY NO. 2) (POINT SIDE) → HEAD (LH–UPR) FUSE → HEADLIGHT HI LH → HEADLIGHT HI RH → TERMINAL (A)5 OF DAYTIMERUNNING LIGHT RELAY NO. 3 → TERMINAL (A)3 → GROUND, CAUSING THE HEADLIGHTS TO LIGHT UP AT APPROX. 20 % OF THEIRNORMAL BRIGHTNESS.

ONCE THE DAYTIME RUNNING LIGHT RELAY (MAIN) HAS BEEN ACTIVATED AND THE HEADLIGHTS LIGHT UP, THE HEADLIGHTSREMAIN ON EVEN IF THE PARKING BRAKE LEVER IS ENGAGED AGAIN (PARKING BRAKE SW ON).

2. HEADLIGHT OPERATIONWHEN THE LIGHT CONTROL SW IS AT HEAD POSITION AND THE DIMMER SW AT LOW POSITION, CURRENT FLOWS FROM THEHEADLIGHT RELAY (COIL SIDE) TO TERMINAL 6 OF THE INTEGRATION RELAY → TERMINAL 7 → TERMINAL 13 OF LIGHT CONTROLSW → TERMINAL 11 → GROUND, ACTIVATING THE HEADLIGHT RELAY.

THIS CAUSES CURRENT TO FLOW FROM THE HEADLIGHT RELAY (POINT SIDE) TO THE HEAD LWR FUSE → HEADLIGHT LO →GROUND, CAUSING THE HEADLIGHTS TO LIGHT UP AT NORMAL BRIGHTNESS. SIMULTANEOUSLY, CURRENT FLOWS FROM THEDRL FUSE → DAYTIME RUNNING LIGHT RELAY NO. 3 (COIL SIDE) → GROUND, ACTIVATING RELAY NO. 3.

WHEN THE DIMMER SW IS AT HIGH POSITION, TERMINAL 12 OF THE DIMMER SW OUTPUTS A SIGNAL TO TERMINAL 16 OF THEDAYTIME RUNNING LIGHT RELAY (MAIN) TO ACTIVATE IT. THIS TURNS ON DIMMER RELAY (DAYTIME RUNNING LIGHT RELAY NO. 2).SO CURRENT FLOWS FROM DIMMER RELAY (DAYTIME RUNNING LIGHT RELAY NO. 2) (POINT SIDE) TO THE HEAD (LH–UPR) FUSE→ HEADLIGHT HI LH → DAYTIME RUNNING LIGHT RELAY NO. 3 (POINT SIDE) → GROUND, AND FROM THE HEAD (RH–UPR) FUSE →DAYTIME RUNNING LIGHT RELAY NO. 3 (POINT SIDE) → HEADLIGHT HI RH → DAYTIME RUNNING LIGHT RELAY NO. 3 (POINT SIDE)→ GROUND, CAUSING THE HEADLIGHTS TO OPERATE AT HI.

WHEN THE DIMMER SW IS AT FLASH POSITION, CURRENT FROM THE HEADLIGHT RELAY (COIL SIDE) FLOWS TO TERMINAL 14 OFTHE DIMMER SW → TERMINAL 9 → GROUND, ACTIVATING THE RELAY. SIMULTANEOUSLY, CURRENT FROM THE HEADLIGHT RELAY(POINT SIDE) FLOWS TO HEADLIGHT LO, LIGHTING UP HEADLIGHT LO AND ACTIVATING DAYTIME RUNNING LIGHT RELAY NO. 3.THEN TERMINAL 12 OF THE DIMMER SW OUTPUTS A SIGNAL TO TERMINAL 16 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN),ACTIVATING THE DAYTIME RUNNING LIGHT RELAY (MAIN) SO THAT CURRENT FLOWS TO HEADLIGHT HI LIKE IT DOES FOR HIGHPOSITION. THIS CAUSES ALL HEADLIGHTS TO LIGHT UP.

TAILLIGHT

WHEN THE LIGHT CONTROL SW IS TURNED TO TAIL OR HEAD POSITION. THE CURRENT FLOWS TO TERMINAL 3 OF THE LIGHTFAILURE SENSOR THROUGH THE TAIL FUSE.

WHEN THE IGNITION SW IS TURNED ON, THE CURRENT FLOWS FROM THE GAUGE FUSE TO TERMINAL 8 OF THE LIGHT FAILURESENSOR, ANO ALSO FLOWS THROUGH THE REAR LIGHT WARNING LIGHT TO TERMINAL 4 OF THE LIGHT FAILURE SENSOR.

TAILLIGHT DISCONNECTION WARNINGWITH THE IGNITION SW ON AND THE LIGHT CONTROL SW TURNED TO TAIL OR HEAD POSITION, IF THE TAILLIGHT CIRCUIT ISOPEN, THE LIGHT FAILURE SENSOR DETECTS THE FAILURE BY THE CHANGE IN CURRENT FLOWING FROM TERMINAL 3 OF THELIGHT FAILURE SENSOR TO TERMINAL 9 , 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 → TERMINAL 11 → GROUND AND TURNSTHE REAR LIGHT WARNING LIGHT ON, WHICH REMAINS ON UNTIL THE LIGHT CONTROL SW IS TURNED OFF.

WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS TO TERMINAL 7 OF THE INTEGRATION RELAY THROUGH GAUGEFUSE.

VOLTAGE IS APPLIED AT ALL TIMES TO TERMINAL (A) 5 OF THE INTEGRATION RELAY THROUGH THE TAILLIGHT RELAY COIL, ANDTO TERMINAL (A) 6 THROUGH THE HEADLIGHT RELAY COIL.

1. NORMAL LIGHTING OPERATION(TURN TAILLIGHT ON)

WITH LIGHT CONTROL SW TURNED TO TAIL POSITION, A SIGNAL IS INPUT INTO TERMINAL (A) 4 OF THE INTEGRATION RELAY. DUETO THIS SIGNAL, THE CURRENT FLOWING TO TERMINAL (A) 5 OF THE RELAY FLOWS TO TERMINAL (A) 4 → TERMINAL 2 OF THELIGHT CONTROL SW → TERMINAL 11 → TO GROUND, AND TAILLIGHT RELAY CAUSES TAILLIGHTS TO TURN ON.

(TURN HEADLIGHT ON)

WITH LIGHT CONTROL SW TURNED TO HEAD POSITION, A SIGANL IS INPUT INTO TERMINAL (A) 4 AND (A) 7 OF THE INTEGRATIONRELAY. DUE TO THIS SIGNAL, THE CURRENT FLOWING TO TERMINAL (A) 6 OF THE RELAY FLOWS TO TERMINAL (A) 7 → TERMINAL13 OF THE LIGHT CONTROL SW → TERMINAL 11 → TO GROUND IN THE HEADLIGHT CIRCUIT, AND CAUSES TAILLIGHT ANDHEADLIGHT RELAY TO TURN THE LIGHTS ON. THE TAILLIGHT CIRCUIT IS SAME AS ABOVE.

2. LIGHT AUTO TURN OFF OPERATIONWITH LIGHT ON AND THE IGNITION SW TURNED OFF (INPUT SIGNAL GOES TO TERMINAL 7 OF THE RELAY), WHEN THE DRIVER’SDOOR IS OPENED (INPUT SIGNAL GOES TO TERMINAL 6 OF THE RELAY), THE RELAY OPERATES AND THE CURRENT IS CUT OFFWHICH FLOWS FROM TERMINAL (A) 5 OF THE RELAY TO TERMINAL (A) 4 IN TAILLIGHT CIRCUIT AND FROM TERMINAL (A) 6 TOTERMINAL (A) 7 IN HEADLIGHT CIRCUIT.

AS A RESULT, ALL LIGHTS ARE TURNED OFF AUTOMATICALLY.

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 ALSOFLOWS THROUGH THE REAR LIGHT WARNING LIGHT TO TERMINAL 4 OF THE LIGHT FAILURE SENSOR.

STOP LIGHT DISCONNECTION WARNING

WHEN THE IGNITION SW IS TURNED ON AND THE BRAKE PEDAL IS PRESSED (STOP LIGHT SW ON), IF THE STOP LIGHT CIRCUIT IS OPEN, THECURRENT FLOWING FROM TERMINAL 7 OF THE LIGHT FAILURE SENSOR TO TERMINAL 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 → TERMINAL 11 → GROUND AND TURNS THE REAR LIGHTWARNING LIGHT ON. BY PRESSING THE BRAKE PEDAL, THE CURRENT FLOWING TO TERMINAL 8 OF THE LIGHT FAILURE SENSOR KEEPS THEWARNING CIRCUIT ON HOLDING AND THE WARNING LIGHT ON UNTIL THE IGNITION SW IS TURNED OFF.

CURRENT ALWAYS FLOWS TO TERMINAL (A)9 OF THE THEFT DETERRENT ECU THROUGH THE DOOR FUSE, AND TO TERMINAL(B)1 THROUGH THE DOME FUSE.

WHEN THE IGNITION SW TURNED ON, THE CURRENT FLOWING THROUGH THE ECU–IG FUSE → TERMINAL (A)7 OF THE ECU →TERMINAL (A)6 FLOWS THROUGH THE COIL SIDE OF THE POWER MAIN RELAY TO GROUND, CAUSING THE RELAY TO OPERATE.THE CURRENT FLOWING THROUGH THE DOOR FUSE FLOWS TO THE DOOR LOCK CONTROL SWITCHES, CAUSING THE INDICATORLIGHT TO LIGHT UP.

1. MANUAL LOCK OPERATIONWHEN THE DOOR CONTROL SW OR KEY SW ARE PUSHED TO LOCK POSITION, A LOCK SIGNAL IS INPUT TO TERMINAL (B)5, (B)22(FOR KEY SW) OF THE THEFT DETERRENT ECU AND CAUSES THE ECU TO FUNCTION. CURRENT FLOWS FROM TERMINAL (A)9 OFTHE ECU → TERMINAL (A)3 → TERMINAL 2 (LH), TERMINAL 4 (RH) OF THE DOOR LOCK MOTORS → TERMINAL 4 (LH), TERMINAL 2(RH) → TERMINAL (A)2 OF THE ECU → TERMINAL (A)4 → GROUND AND THE DOOR LOCK MOTOR CAUSES THE DOOR TO LOCK.

2. MANUAL UNLOCK OPERATIONWHEN THE DOOR LOCK CONTROL SW OR KEY SW ARE PUSHED TO UNLOCK POSITION, AN UNLOCK SIGNAL IS INPUT TOTERMINAL (A)8, (B)6 (FOR KEY SW LH) OR (B)16 (FOR KEY SW RH) OF THE THEFT DETERRENT ECU AND CAUSES TO FUNCTION.CURRENT FLOWS FROM TERMINAL (A)9 OF THE ECU → TERMINAL (A)2 → TERMINAL 4 (LH), TERMINAL 2 (RH) OF THE DOOR LOCKMOTORS → TERMINAL 2 (LH), TERMINAL 4 (RH) → TERMINAL (A)3 OF THE ECU → TERMINAL (A)4 → GROUND AND THE DOORLOCK MOTOR CAUSES THE DOOR TO UNLOCK.

WHEN UNLOCK OPERATION OCCURS USING THE LH DOOR KEY SW, DOING THE UNLOCK OPERATION ONCE UNLOCKS ONLY THEDRIVER’S DOOR. TO UNLOCK ALL THE OTHER DOORS TOGETHER, UNLOCK OPERATION MUST BE DONE AGAIN WITHIN 3SECONDS OF THE FIRST OPERATION.

3. IGNITION KEY REMINDER OPERATION∗ OPERATION OF DOOR LOCK BUTTON (OPERATION OF DOOR LOCK MOTORS)

WHEN THE IGNITION KEY IS IN THE CYLINDER (UNLOCK WARNING SW ON) AND THE DOOR IS OPENED AND LOCKED USING DOORLOCK BUTTON (DOOR LOCK MOTOR), THE DOOR IS LOCKED ONCE BUT EACH DOOR IS UNLOCKED SOON BY THE OPERATION OFTHE ECU. AS A RESULT OF ECU ACTIVATION, THE CURRENT FLOWS FROM TERMINAL (A)9 OF THE ECU → TERMINAL (A)2 →TERMINAL 4 (LH), TERMINAL 2 (RH) OF THE DOOR LOCK MOTORS → TERMINAL 2 (LH), TERMINAL 4 (RH) → TERMINAL (A)3 OF THEECU → TERMINAL (A)4 → GROUND AND CAUSES ALL THE DOOR LOCK CONTROL SW AND DOOR LOCK KEY SW.

∗ KEY LESS LOCK OPERATION

WHEN THE IGNITION KEY IS STILL INSERTED IN THE CYLINDER (UNLOCK WARNING SW ON), THE DOOR IS OPEN AND UNLOCKOPERATION IS PREVENTED BY KEEPING THE DOOR LOCK BUTTON PRESSED TO THE LOCK SIDE, THE DOOR IS KEPT IN THE LOCKCONDITION. IF THE DOOR IS THEN CLOSED, A SIGNAL IS INPUT TO THE ECU FROM THE DOOR COURTESY SW. THIS ACTIVATESTHE ECU AND EACH DOOR IS UNLOCKED.

POWER WINDOW

WITH THE IGNITION SW TURNED ON, CURRENT FLOWS THROUGH THE ECU–IG FUSE → TERMINAL (A)7 OF THE THEFTDETERRENT ECU → TERMINAL (A)6 → TERMINAL 1 OF THE POWER MAIN RELAY → TERMINAL 2 → GROUND, THIS ACTIVATES THERELAY AND THE CURRENT FLOWING TO TERMINAL 5 OF THE RELAY FROM DOOR FUSE FLOWS TO TERMINAL 3 OF THE RELAY →TERMINAL 4 OF THE POWER WINDOW MASTER SW AND TERMINAL 4 OF THE POWER WINDOW CONTROL SW RH.

1. MANUAL OPERATION (DRIVER’S WINDOW)WITH THE IGNITION SW TURNED ON AND WITH THE POWER WINDOW MASTER SW (DRIVER’S) IN UP POSITION, THE CURRENTFLOWING TO TERMINAL 4 OF THE POWER WINDOW MASTER SW FLOWS TO TERMINAL 10 OF THE MASTER SW → TERMINAL 1 OFTHE POWER WINDOW MOTOR → TERMINAL 2 → TERMINAL 9 OF THE MASTER SW → TERMINAL 8 → GROUND AND CAUSES THEPOWER 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 4 OF THE POWER WINDOW MASTER SW TO TERNINAL 9 OF THEMASTER SW CAUSES THE FLOW OF CURRENT FROM TERMINAL 2 OF THE POWER WINDOW MOTOR → TERMINAL 1 → TERMINAL10 OF THE MASTER SW → TERMINAL 8 → GROUND, FLOWING IN THE OPPOSITE DIRECTION TO MANUAL UP OPERATION ANDCAUSING THE MOTOR TO ROTATE IN REVERSE, LOWERING THE WINDOW.

2. DRIVER’S WINDOW AUTO DOWN OPERATIONWHEN THE DRIVER’S WINDOW SW IS PUSHED STRONGLY ON THE DOWN SIDE, THE CURRENT FLOWING TO TERMINAL 4 OF THEPOWER WINDOW MASTER SW FLOWS TO THE DOWN CONTACT POINT AND AUTO DOWN CONTACT POINT OF THE DRIVER’S SW.

THIS ACTIVATES THE RELAY (DOWN SIDE) INSIDE THE POWER WINDOW MASTER SW, AND THE HOLD CIRCUIT ALSO TURNS ON ATTHE SAME TIME, SO THE RELAY (DOWN SIDE) REMAINS ACTIVATED EVEN WHEN THE SW IS RELEASED.

CURRENT FLOWS AT THIS TIME FROM TERMINAL 4 OF THE POWER WINDOW MASTER SW → TERMINAL 9 → TERMINAL 2 OFPOWER WINDOW MOTOR → TERMINAL 1 → TERMINAL 10 OF POWER WINDOW MASTER SW → TERMINAL 8 → GROUND, SO THEMOTOR CONTINUES TO OPERATE UNTIL THE DRIVER’S WINDOW IS FULLY DOWN.

WHEN THE DRIVER’S WINDOW FINISHES DOWN OPERATION THE HOLD CIRCUIT GOES OFF, SO THE RELAY (DOWN SIDE) ALSOTURNS OFF. THIS STOPS THE CURRENT FLOWING FROM TERMINAL 4 OF THE POWER WINDOW MASTER SW TO TERMINAL 9 , SOTHE POWER WINDOW MOTOR STOPS AND AUTO DOWN OPERATION STOPS.

WHEN THE DRIVER’S SW IS PULLED ON THE UP SIDE DURING AUTO DOWN OPERATION, THE HOLD CIRCUIT IS TURNED OFF SOCURRENT FLOWS FROM TERMINAL 4 OF THE POWER WINDOW MASTER SW TO TERMINAL 9 IS CUT OFF AND THE POWERWINDOW MOTOR STOPS. IF THE SW REMAINS PULLED UP, THE RELAY (UP SIDE) IS ACTIVATED, SO CURRENT FLOWS FROMTERMINAL 4 OF THE POWER WINDOW MASTER SW → TERMINAL 10 → TERMINAL 1 OF POWER WINDOW MOTOR → TERMINAL 2 →TERMINAL 9 → TERMINAL 8 → GROUND, THE POWER WINDOW MOTOR ROTATES IN THE UP DIRECTION AND MANUAL UPOPERATION OCCURS WHILE THE SW IS PULLED UP.

3. MANUAL OPERATION BY POWER WINDOW SW (PASSENGER’S WINDOW)WITH POWER WINDOW SW (PASSENGER’S) PULLED TO THE UP SIDE, CURRENT FLOWING FROM TERMINAL 4 OF THE POWERWINDOW CONTROL SW FLOWS TO TERMINAL 1 OF THE POWER WINDOW SW → TERMINAL 2 OF THE POWER WINDOW MOTOR →TERMINAL 1 → TERMINAL 3 OF THE POWER WINDOW SW → TERMINAL 5 → TERMINAL 7 OF THE MASTER SW → TERMINAL 8 →GROUND AND CAUSES THE POWER WINDOW MOTOR (PASSENGER’S) TO ROTATE IN THE UP DIRECTION. UP OPERATIONCONTINUES ONLY WHILE THE POWER WINDOW SW IS PULLED TO THE UP SIDE. WHEN THE POWER WINDOW SW (PASSENGER’S)IS PULLED TO THE DOWN SIDE, THE CURRENT FLOWING TO THE MOTOR FLOWS IN THE OPPOSITE DIRECTION, FROM TERMINAL 1TO TERMINAL 2 , AND THE MOTOR ROTATES IN REVERSE. WHEN THE WINDOW LOCK SW IS PUSHED TO THE LOCK SIDE, THEGROUND 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 OFTHE POWER WINDOW MASTER SW IS NOT GROUNDED AND THE MOTOR DOES NOT ROTATE, SO THE PASSENGER’S WINDOWCANNOT BE OPERATED AND WINDOW LOCK OCCURS. FURTHERMORE, REAR LH, RH WINDOW OPERATE THE SAME AS THEABOVE CIRCUIT.

4. KEY OFF POWER WINDOW OPERATIONWITH THE IGNITION SW TURNED FROM ON TO OFF, THE THEFT DETERRENT ECU OPERATES AND CURRENT FLOWS FROM DOORFUSE TO TERMINAL (A)9 OF THE ECU OR DOME FUSE TO TERMINAL (B)1 OF THE ECU → TERMINAL (A)6 → TERMINAL 1 OF POWERMAIN RELAY → TERMINAL 2 → GROUND FOR ABOUT 60 SECONDS. THE SAME AS NORMAL OPERATION, THE CURRENT FLOWSFROM DOOR FUSE → TERMINAL 5 OF THE POWER MAIN RELAY → TERMINAL 3 → TERMINAL 4 OF THE POWER WINDOW MASTERSW AND TERMINAL 4 OF THE POWER WINDOW CONTROL SW RH. AS A RESULT, FOR ABOUT 60 SECONDS AFTER THE IGNITION SWIS TURNED OFF, THE FUNCTIONING OF THIS RELAY MAKES IT POSSIBLE TO RAISE AND LOWER THE POWER WINDOW. ALSO, BYOPENING THE FRONT DOOR (DOOR OPEN DETECTION SW ON) WITHIN ABOUT 60 SECONDS AFTER TURNING THE IGNITION SW TOOFF, A SIGNAL IS INPUT TO TERMINAL (B)19, (B)7 OF THEFT DETERRENT ECU. AS A RESULT, THE ECU TURNED OFF AND UP ANDDOWN MOVEMENT OF THE POWER WINDOW STOPS.

THIS SYSTEM ELECTRICALLY CONTROLS THE LINE PRESSURE, THROTTLE PRESSURE, LOCK–UP PRESSURE AND ACCUMULATOR PRESSURE ETC.THROUGH THE SOLENOID VALVE. THE ELECTRONICALLY CONTROLLED TRANSMISSION IS A SYSTEM WHICH PRECISELY CONTROLS GEAR SHIFTTIMING AND LOCK–UP TIMING IN RESPONSE TO THE VEHICLE’S DRIVING CONDITIONS AND THE ENGINE OPERATING CONDITIONS DETECTED BYVARIOUS SENSORS, MAKING SMOOTH DRIVING POSSIBLE BY SHIFT SELECTION FOR EACH GEAR WHICH IS THE MOST APPROPRIATE TO THEDRIVING CONDITIONS AT THAT TIME, AND CONTROLS THE ENGINE TORQUE DURING SHIFTING TO ACHIEVE OPTIMUM SHIFT FEELING.

1. GEAR SHIFT OPERATIONWHEN DRIVING, THE ENGINE WARM UP CONDITION IS INPUT AS A SIGNAL TO TERMINAL (B)44 OF THE ENGINE CONTROL MODULE(ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) FROM THE ENGINE COOLANT TEMP. SENSOR (EFI WATER TEMP.SENSOR) AND THE VEHICLE SPEED SIGNAL FROM VEHICLE SPEED SENSOR (SPEED SENSOR) NO.2 IS INPUT TO TERMINAL (B) 23 OF THEENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU). AT THE SAME TIME, THE THROTTLEVALVE OPENING SIGNAL FROM THE THROTTLE POSITION SENSOR (MAIN) IS INPUT TO TERMINAL (B)43 OF THE ENGINE CONTROLMODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) AS THROTTLE ANGLE SIGNAL.

BASED ON THESE SIGNALS, THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU)SELECTS THE BEST SHIFT POSITION FOR DRIVING CONDITIONS AND SENDS CURRENT TO THE ELECTRONICALLY CONTROLLEDTRANSMISSION SOLENOIDS.

WHEN SHIFTING TO 1ST SPEED, THE CURRENT FLOWS FROM TERMINAL (B)10 OF THE ENGINE CONTROL MODULE (ENGINE ANDELECTRONICALLY CONTROLLED TRANSMISSION ECU) → TERMINAL 4 OF ELECTRONICALLY CONTROLLED TRANSMISSION SOLENOID →GROUND AND CONTINUITY TO NO. 1 SOLENOID CAUSES THE SHIFT (NO. 2 SOLENOID DOES NOT HAVE CONTINUITY AT THIS TIME).

FOR 2ND SPEED, THE CURRENT FLOWS SIMULTANEOUSLY FROM TERMINAL (B)9 OF THE ENGINE CONTROL MODULE (ENGINE ANDELECTRONICALLY CONTROLLED TRANSMISSION ECU) → TERMINAL 8 OF ELECTRONICALLY CONTROLLED TRANSMISSION SOLENOID →GROUND, AND FROM TERMINAL (B)10 OF THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSIONECU) → TERMINAL 4 OF ELECTRONICALLY CONTROLLED TRANSMISSION SOLENOID → GROUND, AND CONTINUITY TO NO. 1 AND NO. 2SOLENOIDS CAUSES THE SHIFT.

FOR 3RD SPEED, THERE IS NO CONTINUITY TO NO. 1 SOLENOID, ONLY TO NO. 2 SOLENOID, CAUSING THE SHIFT.

SHIFTING INTO THE 4TH SPEED (OVERDRIVE) OCCURS WHEN NO CURRENT FLOWS TO NO. 1 AND NO. 2 SOLENOIDS. THE NO. 4 SOLENOID (FORACCUMULATOR BACK PRESSURE MODULATION) IS INSTALLED TO ADJUST THE BACK PRESSURE ON THE ACCUMULATOR AND CONTROLS THEHYDRAULIC PRESSURE DURING SHIFTING AND LOCK–UP IN ORDER TO PROVIDE SMOOTH SHIFTING WITH LITTLE SHIFT SHOCK.

2. LOCK–UP OPERATIONWHEN THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) DECIDES, BASED ON EACHSIGNAL, THAT THE LOCK–UP CONDITION HAS BEEN MET, THE CURRENT THROUGH EFI NO. 1 FUSE FLOWS FROM THE EFI MAIN RELAY →TERMINAL 3 OF THE ELECTRONICALLY CONTROLLED TRANSMISSION SOLENOID → TERMINAL 7 → TERMINAL (B)14 OF THE ENGINECONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) → GROUND, SO CONTINUITY TO NO. 3 (FORLOCK–UP) CAUSES LOCK–UP.

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 (A)4OF THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU). THE ENGINE CONTROL MODULE(ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) OPERATES AND CUTS THE CURRENT TO THE SOLENOID TO RELEASELOCK–UP.

4. OVERDRIVE CIRCUIT

* O/D MAIN SW ON

WHEN THE O/D MAIN SW IS TURNED ON (SW POINT IS OPEN), A SIGNAL IS INPUT TO TERMINAL (A)28 OF THE ENGINE CONTROLMODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) AND THE ELECTRONICALLY CONTROLLED TRANSMISSIONCAUSES SHIFT TO OVERDRIVE WHEN THE CONDITIONS FOR OVERDRIVE ARE MET.

* O/D MAIN SW OFF

WHEN THE O/D MAIN SW IS TURNED OFF (SW POINT IS CLOSED), THE CURRENT FLOWING THROUGH THE O/D OFF INDICATOR LIGHTFLOWS TO GROUND BY WAY OF THE O/D MAIN SW AND CAUSES THE O/D OFF INDICATOR LIGHT TO LIGHT UP. AT THE SAME TIME, ASIGNAL IS INPUT TO TERMINAL (A)28 OF THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSIONECU) AND THE ELECTRONICALLY CONTROLLED TRANSMISSION PREVENTS SHIFT INTO OVERDRIVE.

5. ELECTRONICALLY CONTROLLED TRANSMISSION PATTERN SELECT SW CIRCUITWHEN THE ELECTRONICALLY CONTROLLED TRANSMISSION PATTERN SELECT SW IS SWICHED FROM NORMAL TO MANUAL, A SIGNAL ISINPUT TO TERMINAL (A)18 OF THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU). INPUTOF THIS SIGNAL CAUSES CURRENT TO FLOW FROM THE GAUGE FUSE TO TERMINAL (A)1 OF COMBINATION METER → TERMINAL (A)12 →TERMINAL (A)25 OF ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) → GROUND,LIGHTING UP THE INDICATOR LIGHT. IF THE A/T SHIFT LEVER IS THEN SHIFTED TO “2” POSITION, THE ENGINE CONTROL MODULE(ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) ENABLES THE VEHICLE TO START OFF WITH THE TRANSMISSION IS2ND GEAR, THUS PERMITTING EASING STARTING OFF AND DRIVING ON SLIPPERY ROADS.

6. CRUISE CONTROLWHEN CRUISE CONTROL OPERATION IS SELECTED A SIGNAL IS INPUT TO TERMINAL (A)12 OF THE ENGINE CONTROL MODULE (ENGINEAND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) FROM CRUISE CONTROL. ECU. AS A RESULT, THE ENGINE CONTROL MODULE(ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) OPERATES AND CONTROLS OVERDRIVE, LOCK–UP AND SO ON FORSMOOTH DRIVING.

(FOR ABS)

THIS SYSTEM CONTROLS THE RESPECTIVE BRAKE FLUID PRESSURES ACTING ON THE DISC BRAKE CYLINDERS OF THE RIGHTFRONT WHEEL, LEFT FRONT WHEEL, RIGHT REAR WHEEL AND LEFT REAR WHEEL WHEN THE BRAKES ARE APPLIED IN A PANICSTOP SO THAT THE WHEELS DO NOT LOCK.

THIS RESULTS IN IMPROVED DIRECTIONALLY STABILITY AND STEERABILITY DURING PANIC BRAKING.

1. INPUT SIGNALS(1) SPEED SENSOR SIGNAL

THE SPEED OF THE WHEELS IS DETECTED AND INPUT TO TERMINALS FL+, FR+, RL+ AND RR+ OF THE ABS AND TRACTION ECU.

(2) STOP LIGHT SW SIGNALA SIGNAL IS INPUT TO TERMINAL STP OF THE ABS AND TRACTION ECU WHEN THE BRAKE PEDAL IS DEPRESSED.

(3) PARKING BRAKE SW SIGNALA SIGNAL IS INPUT TO TERMINAL PKB OF THE ABS AND TRACTION ECU WHEN THE PARKING BRAKE LEVER IS PULLED UP.

(4) DECELERATION SENSOR SIGNALLATERAL ACCELERATION IS DETECTED AND INPUT TO THE ABS AND TRACTION ECU.

2. SYSTEM OPERATIONDURING SUDDEN BRAKING, THE ABS AND TRACTION ECU WHICH HAS SIGNALS INPUT FROM EACH SENSOR CONTROLS THECURRENT FLOWING TO THE SOLENOID INSIDE THE ACTUATOR AND LETS THE HYDRAULIC PRESSURE ACTING ON EACH WHEELCYLINDER ESCAPE TO THE RESERVOIR. THE PUMP INSIDE THE ACTUATOR IS ALSO OPERATING AT THIS TIME AND IT RETURNSTHE BRAKE FLUID FROM THE RESERVOIR TO THE MASTER CYLINDER, THUS PREVENTING LOCKING OF THE VEHICLE WHEELS.

IF THE ECU JUDGES THAT THE HYDRAULIC PRESSURE ACTING ON THE WHEEL CYLINDER IS INSUFFICIENT, THE CURRENTACTING ON SOLENOID IS CONTROLLED AND THE HYDRAULIC PRESSURE IS INCREASED, HOLDING OF THE HYDRAULICPRESSURE IS ALSO CONTROLLED BY THE ECU, BY THE SAME METHOD AS ABOVE. BY REPEATED PRESSURE REDUCTION,HOLDING AND INCREASE ARE REPEATED TO MAINTAIN VEHICLE STABILITY AND TO IMPROVE STEERABILITY DURING SUDDENBRAKING.

(FOR TRACTION CONTROL)

THE TRACTION CONTROL SYSTEM IS A SYSTEM WHEREBY THE “ABS AND TRACTION ECU” AND “TRACTION ECU” CONTROLS THEENGINE TORQUE AND THE HYDRAULIC PRESSURE OF THE WHEEL CYLINDER OF THE DRIVING WHEELS IN ORDER TO CONTROLSPINNING OF THE DRIVING WHEELS WHEN STARTING OFF AND ACCELERATING, AND PROVIDE THE MOST APPROPRIATE DRIVINGFORCE IN RESPONSE TO THE ROAD CONDITIONS FOR VEHICLE STABILITY.

TRACTION CONTROL OPERATIONVEHICLE SPEED SIGNALS FROM THE SPEED SENSOR INSTALLED ON EACH WHEEL ARE INPUT TO THE ABS AND TRACTION ECU.

WHEN THE ACCELERATOR PEDAL IS DEPRESSED WHILE DRIVING ON A SLIPPERY ROAD AND THE DRIVING WHEEL (REAR WHEEL)SLIPS, IF THE ROTATION OF THE REAR WHEEL EXCEEDS THE ROTATION OF THE FRONT WHEELS FOR A SPECIFIED PERIOD, THEECU JUDGES THAT THE REAR WHEEL IS SLIPPING.

WHEN THIS OCCURS, CURRENT FLOWS FROM TRACTION ECU TO SUB THROTTLE ACTUATOR TO CLOSE THE SUB THROTTLEVALVE. AT THE SAME TIME, OPERATION OF THE ABS AND TRACTION ECU CAUSE THE TRACTION BRAKE ACTUATORS (MASTERCYLINDER CUT, RESERVOIR CUT SOLENOID) TO TURN ON TO SWITCH THE HYDRAULIC CIRCUIT TO “TRACTION” MODE.

IN THIS CASE, SIGNALS ARE INPUT FROM TERMINAL SRR OF ABS AND TRACTION ECU TO TERMINAL (B)3 OF ABS ACTUATOR, ANDFROM TERMINAL SRL OF ABS AND TRACTION ECU TO TERMINAL (B)6 OF ABS ACTUATOR, CONTROLLING THE REAR WHEELSOLENOID IN THE ABS ACTUATOR AND INCREASING THE HYDRAULIC PRESSURE OF THE WHEEL CYLINDER IN ORDER TOPREVENT SLIP.

TO MAINTAIN THE HYDRAULIC PRESSURE OF THE REAR WHEELS, THE REAR WHEEL SOLENOID INSIDE THE ABS ACTUATOR ISPUT IN “HOLD” MODE AND KEEPS THE HYDRAULIC PRESSURE TO THE WHEEL CYLINDER CONSTANT.

WHEN THE AMOUNT OF SLIP HAS DECREASED, THE HYDRAULIC PRESSURE IN THE WHEEL CYLINDER DECREASES.

CRUISE CONTROL

CURRENT IS APPLIED AT ALL TIMES THROUGH STOP FUSE TO TERMINAL 1 OF THE CRUISE CONTROL ECU, TERMINAL 2 OF STOPLIGHT SW, AND ALSO THROUGH THE ECU–B FUSE TO TERMINAL 15 OF CRUISE CONTROL ECU.

WITH THE IGNITION SW TURNED TO ON, THE CURRENT FLOWS THROUGH GAUGE FUSE TO TERMINAL (A)9 OF COMBINATIONMETER AND THE CURRENT THROUGH ECU–IG FUSE FLOWS TO TERMINAL 14 OF CRUISE CONTROL ECU.

WHEN THE IGNITION SW IS ON AND THE CRUISE CONTROL MAIN SWITCH IS TURNED ON, A SIGNAL IS INPUT FROM TERMINAL 15OF CRUISE CONTROL MAIN SW TO TERMINAL 19 OF CRUISE CONTROL ECU. AS A RESULT, THE CRUISE CONTROL ECUFUNCTIONS AND THE CURRENT FLOWS THROUGH TERMINAL 14 OF CRUISE CONTROL ECU TO TERMINAL 13 OF CRUISECONTROL ECU → GROUND, AND THE CRUISE CONTROL SYSTEM IS IN A CONDITION READY FOR OPERATION.

AT THE SAME TIME, THE CURRENT THROUGH THE GAUGE FUSE FLOWS TO TERMINAL (A)9 OF CRUISE CONTROL INDICATORLIGHT → TERMINAL (B)6 → TERMINAL 7 OF CRUISE CONTROL ECU → TERMINAL 13 → GROUND. CAUSING THE CRUISE CONTROLINDICATOR LIGHT TO LIGHT UP, 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 SETLIMIT (APPROX. 40 KM/H, 25 MPH TO 200 KM/H, 124 MPH), A SIGNAL IS INPUT TO TERMINAL 18 OF THE CRUISE CONTROL ECU ANDTHE VEHICLE SPEED AT THE TIME THE SET SW IS RELEASED, WHICH 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 VEHICLESPEED INPUTS INTO TERMINAL 20 OF THE CRUISE CONTROL ECU FROM THE SPEED SENSOR, AND CONTROLS THE CRUISECONTROL ACTUATOR TO MAINTAIN THE SET SPEED.

WHEN THE ACTUAL SPEED IS LOWER THAN THE SET SPEED, THE ECU CAUSES THE CURRENT TO THE CRUISE CONTROLACTUATOR TO FLOW FROM TERMINAL 12 → TERMINAL 6 OF CRUISE CONTROL ACTUATOR → TERMINAL 7 → TERMINAL 11 OFCRUISE CONTROL ECU. AS A RESULT, THE MOTOR IN THE CRUISE CONTROL ACTUATOR IS ROTATED TO OPEN THE THROTTLEVALVE AND THE THROTTLE CABLE IS PULLED TO INCREASE THE VEHICLE SPEED. WHEN THE ACTUAL DRIVING SPEED IS HIGHERTHAN THE SET SPEED, THE CURRENT TO CRUISE CONTROL ACTUATOR FLOWS FROM TERMINAL 11 OF ECU → TERMINAL 7 OFCRUISE CONTROL ACTUATOR → TERMINAL 6 → TERMINAL 12 OF CRUISE CONTROL ECU.

THIS CAUSES THE MOTOR IN THE CRUISE CONTROL ACTUATOR TO ROTATE TO CLOSE THE THROTTLE VALVE AND RETURN THETHROTTLE CABLE TO DECREASE THE VEHICLE SPEED.

3. COAST CONTROLDURING THE CRUISE CONTROL DRIVING, WHILE THE COAST SW IS ON, THE CRUISE CONTROL ACTUATOR RETURNS THETHROTTLE CABLE TO CLOSE THE THROTTLE VALVE AND DECREASE THE DRIVING SPEED. THE VEHICLE SPEED WHEN THE COASTSWITCH IS TURNED OFF IS MEMORIZED AND THE VEHICLE CONTINUES AT THE NEW SET SPEED.

4. ACCEL CONTROLDURING CRUISE CONTROL DRIVING, WHILE THE ACCEL SW IS TURNED ON, THE CRUISE CONTROL ACTUATOR PULLS THETHROTTLE CABLE TO OPEN THE THROTTLE 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. 40 KM/H, 25 MPH) AFTER CANCELING THE SETSPEED BY THE CANCEL SW, PUSHING THE RESUME SW WILL CAUSE THE VEHICLE TO RESUME THE SPEED SET BEFORE THECANCELLATION.

6. MANUAL CANCEL MECHANISMIF ANY OF THE FOLLOWING OPERATIONS OCCUR DURING CRUISE CONTROL OPERATION, THE MAGNETIC CLUTCH OF THEACTUATOR TURNS OFF AND THE MOTOR ROTATES TO CLOSE THE THROTTLE VALVE AND THE CRUISE CONTROL IS RELEASED.

∗ PLACING THE SHIFT LEVER IN EXCEPT “D” POSITION (PARK/NEUTRAL POSITION SW (NEUTRAL START SW EXCEPT “D” POSITION)). “SIGNAL IS NOT INPUT TO TERMINAL 2 OF ECU” (A/T).

∗ DEPRESSING THE BRAKE PEDAL (STOP LIGHT SW ON). “SIGNAL IS INPUT TO TERMINAL 16 OF ECU”

∗ PULLING THE PARKING BRAKE LEVER (PARKING BRAKE SW ON). “SIGNAL INPUT TO TERMINAL 3 OF ECU”

∗ PUSHING THE CANCEL SWITCH (CANCEL SW ON). “SIGNAL IS INPUT TO TERMINAL 18 OF ECU”

∗ DEPRESSING THE CLUTCH PEDAL (CRUISE CONTROL CLUTCH SW OFF). “SIGNAL IS NOT INPUT TO TERMINAL 2 OF ECU”

7. AUTO CANCEL FUNCTIONA) IF ANY OF THE FOLLOWING OPERATING CONDITIONS OCCUR DURING CRUISE CONTROL OPERATION, THE SET SPEED ISERASED, CURRENT FLOW TO MAGNETIC CLUTCH IS STOPPED AND THE CRUISE CONTROL IS RELEASED. (MAIN 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.

∗ WHEN CURRENT CONTINUED TO FLOW TO THE MOTOR INSIDE THE ACTUATOR IN THE THROTTLE VALVE “OPEN” DIRECTION.

∗ 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 OCCUR DURING CRUISE CONTROL OPERATION, THE SET SPEED IS ERASED ANDTHE CRUISE CONTROL IS RELEASED. (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 CONDITIONS OCCUR DURING CRUISE CONTROL OPERATION, THE CRUISE CONTROL ISRELEASED.

∗ OPEN CIRCUIT FOR TERMINAL 1 OF CRUISE CONTROL ECU AND TERMINAL 2 OF STOP LIGHT SW.

8. AUTOMATIC TRANSMISSION CONTROL FUNCTION∗ IN OVERDRIVE. IF THE VEHICLE SPEED BECOMES LOWER THAN THE OVERDRIVE CUT SPEED (SET SPEED MINUS APPROX. 4KM/H, 2.5 MPH) DURING CRUISE CONTROL OPERATION, SUCH AS DRIVING UP A HILL, THE OVERDRIVE IS RELEASED AND THEPOWER INCREASED TO PREVENT A REDUCTION IN VEHICLE SPEED.

∗ AFTER RELEASING THE OVERDRIVE, VEHICLE SPEED BECOMES HIGHER THAN THE OVERDRIVE RETURN SPEED (SET SPEEDMINUS APPROX. 2 KM/H, 1.2 MPH) AND THE ECU JUDGES BY THE SIGNALS FROM POTENTIONMETER OF THE ACTUATOR THATTHE UPWARD SLOPE HAS FINISHED, OVERDRIVE IS RESUMED AFTER APPROXIMATELY 2 SECONDS.

∗ DURING CRUISE CONTROL DRIVING, THE CRUISE CONTROL OPERATION SIGNAL IS OUTPUT FROM THE CRUISE CONTROLECU TO THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU). UPON RECEIVINGTHIS SIGNAL, THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU) CHANGESTHE SHIFT PATTERN TO NORMAL.

TO MAINTAIN SMOOTH CRUISE CONTROL OPERATION (ON A DOWNWARD SLOPE ETC.), LOCK–UP RELEASE OF THETRANSMISSION WHEN THE IDLING POINT OF THE THROTTLE POSITION IS “ON” IS FORBIDDEN.

THE PPS (HYDRAULIC REACTION TYPE) CONTROLS THE HYDRAULIC PRESSURE APPLIED TO THE HYDRAULIC REACTIONCHAMBER IN THE GEAR BOX CONTROL UNIT USING THE PPS ECU, TO CHANGE THE STEERING FORCE AND PROVIDE OPTIMUMSTEERING FEELING AT ANY VEHICLE SPEEDS AND UNDER ANY STEERING CONDITIONS.

(PPS OPERATION)

WHEN THE IGNITION SW IS TURNED ON THE STARTING CURRENT FLOWS FROM THE ECU–IG FUSE TO TERMINAL 4 OF THE PPSECU. THE PPS ECU MONITORS VEHICLE SPEED, INPUT SIGNAL TO TERMINAL 5 OF THE ECU. WHEN THE VEHICLE SPEED IS LOW,THE PPS ECU SENDS A HIGHER–CURRENT FROM TERMINAL 1 OF THE ECU → TERMINAL 1 OF THE SOLENOID VALVE → TERMINAL2 → TERMINAL 2 OF THE ECU → TERMINAL 6 → GROUND, INCREASING THE SOLENOID VALVE OPENING ANGLE TO PROVIDECOMFORTABLE STEERING OPERATION. WHEN THE VEHICLE SPEED IS HIGH, THE PPS ECU DECREASES THE SOLENOID VALVEOPENING ANGLE BY REDUCING THE CURRENT TO THE VALVE TO PROVIDE RESPONSIVE STEERING FEELING.

SRS (SUPPLEMENTAL RESTRAINT SYSTEM)

NOTICE: When inspecting or repairing the SRS (supplemental restraint system), perform the operation inaccordance with the following precautionary instructions and the procedure and precautions in the RepairManual for the applicable model year. Malfunction symptoms of the supplemental restraint system are difficult to confirm, so the diagnostic trouble

codes become the most important source of information when troubleshooting.When troubleshooting the supplemental restraint system, always inspect the diagnostic trouble codes beforedisconnecting the battery.

Work must be started after 90 seconds from the time the Ignition SW is set to the “LOCK” position and thenegative (–) terminal cable is disconnected from the battery.(The supplemental restraint system is equipped with a back–up power source so that if work is started within90 seconds of disconnecting the negative (–) terminal cable of the battery, the SRS may be activated.)When the negative (–) terminal cable is disconnected from the battery, memory of the clock and audio systemswill be cancelled. So before starting work, make a record of the contents memorized by each memory system.When work is finished, reset the clock and audio system as before and adjust the clock.To avoid erasing the memory of each memory system, never use a back–up power supply from outside thevehicle.

When removing the steering wheel pad or handling a new steering wheel pad, keep the pad upper surfacefacing upward. Also, lock the lock lever of the twin lock type connector at the rear of the pad and take carenot to damage the connector.(Storing the pad with its metallic surface up may lead to a serious accident if the SRS inflates for some reason.)

Always store a removed or new front passenger airbag assembly with the airbag door facing up. Storing theairbag assembly with the airbag door facing down could cause a serious accident if the airbag inflates.

Store the steering wheel pad where the ambient temperature remains below 93°C (200°F), without highhumidity and away from electrical noise.

Never use SRS parts from another vehicle. When replacing SRS parts, replace them with new parts. Never disassemble and repair the steering wheel pad, front passenger airbag assembly, 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 reuseit. (See the Repair Manual for the method for evaluating the center airbag sensor assembly.)

When troubleshooting the supplemental restraint system, use a high–impedance (Min. 10k/V) tester. The wire harness of the supplemental restraint system is integrated with the cowl No. 2 wire harness

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

Do not measure the resistance of the airbag squibs.(It is possible this will deploy the airbag and is very dangerous.)

If the wire harness used in the supplemental restraint system is damaged, replace the whole wire harnessassembly.When the connector to the front airbag sensors can be repaired alone (when there is no damage to the wireharness), 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 SRS components. Follow theinstructions on the notices.

198


The supplemental restraint system has connectors which possess the functions described below:1. SRS ACTIVATION PREVENTION MECHANISM

Each connector contains a short spring plate. When theconnector is disconnected, the short spring plateautomatically connects the power source and groundingterminals of the squib to preclude a potential differencebetween the terminals.

2. ELECTRICAL CONNECTION CHECK MECHANISMThis mechanism is designed to electrically check ifconnectors are connected correctly and completely.The electrical connection check mechanism is designed sothat the connection detection pin connects with thediagnosis terminals when the connector housing lock is inthe locked condition.

199

3. CONNECTOR TWIN–LOCK MECHANISMWith this mechanism connectors (male and femaleconnectors) are locked by two locking devices to increaseconnection reliability. If the primary lock is incomplete, ribsinterfere and prevent the secondary lock.

WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS TO TERMINAL 2 OF THE WASHER MOTOR, TERMINAL 1 OF THE REAR WIPERMOTOR AND RELAY THROUGH THE WIPER FUSE.

1. REAR WIPER NORMAL OPERATIONWITH THE IGNITION SW TURNED ON AND THE REAR WIPER AND WASHER SW TURNED ON, THE CURRENT FLOWING TO TERMINAL 1 OFTHE REAR WIPER RELAY FLOWS TO TERMINAL 3 OF THE RELAY → TERMINAL 1 OF THE REAR WIPER AND WASHER SW → TERMINAL 16 →TO GROUND. THUS, THE RELAY COIL IS ACTIVATED AND THE CURRENT TO TERMINAL 1 OF THE REALY FLOWS TO TERMINAL LM →TERMINAL LM OF THE REAR WIPER MOTOR → MOTOR → TO GROUND AND CAUSES THE MOTOR TO OPERATE THE WIPER.

2. REAR WIPER INTERMITTENT OPERATIONWHEN THE IGNITION SW IS ON AND THE REAR WIPER AND WASHER SW IS TURNED TO INT POSITION, CURRENT FLOWING TO TERMINAL 1OF THE REAR WIPER MOTOR AND RELAY FLOWS TO TERMINAL 2 OF THE RELAY → TERMINAL 10 OF THE REAR WIPER AND WASHER SW→ TERMINAL 16 → GROUND.

THIS CAUSES THE MOTOR TO OPERATE (THE POINT CHANGES) AND THE INTERMITTENT CIRCUIT OF THE RELAY OPERATES.INTERMITTENT OPERATION OF THE CIRCUIT IS CONTROLLED BY THE CHANGING AND DISCHARGING OF THE CONDENSER INSTALLEDINSIDE THE RELAY.

3. WASHER OPERATIONWITH THE IGNITION SW TURNED ON AND THE REAR WIPER AND WASHER SW TURNED TO ON POSITION, WHEN THE WIPER SW IS TURNEDFURTHER, THE CURRENT FLOWING TO TERMINAL 2 OF THE WASHER MOTOR FLOWS TO TERMINAL 3 OF THE MOTOR → TERMINAL 2 OFTHE REAR WIPER AND WASHER SW → TERMINAL 16 → TO GROUND, SO THAT THE WASHER MOTOR ROTATES AND THE WINDOW WASHEREJECTS THE SPRAY, ONLY WHILE THE SWITCH IS FULLY TURNED.

WHEN THE WIPER SW IS OFF AND THEN TURNED TO WASHER ON (WIPER OFF SIDE), ONLY THE WASHER OPERATES.

RADIATOR FAN AND AUTOMATIC AIR CONDITIONING

1. HEATER BLOWER OPERATIONMANNAL BLOWER OPERATION

WHEN THE BLOWER CONTROL SW IS SET TO ANY BLOWER SPEEDS, THE A/C AMPLIFIER OPERATES AND THE CURRENT TO DRIVETHE BLOWER MOTOR FLOWS FROM TERMINAL BLW OF THE A/C AMPLIFIER TO TERMINAL SI OF THE BLOWER MOTOR CONTROLRELAY. THE CURRENT ACTIVATES THE RELAY AND THE VOLTAGE APPLIED TO TERMINAL +B OF THE BLOWER MOTOR CONTROLRELAY IS OUTPUT AT TERMINAL M+ AS THE VOLTAGE FOR THE SELECTED BLOWER SPEED. THE CURRENT THEN FLOWS FROMTERMINAL M+ OF THE BLOWER MOTOR CONTROL RELAY TO TERMINAL 2 → TERMINAL 1 → TERMINAL M– OF BLOWER MOTORCONTROL RELAY → TERMINAL GND → GROUND, AND THE BLOWER MOTOR OPERATES AT THE BLOWER SPEED SELECTED.

AUTO FUNCTION

WHEN THE AUTO SW IS TURNED ON, THE A/C AMPLIFIER CALCULATES THE REQUIRED VENT TEMPERATURE BASED ON THE SETTEMPERATURE AND INPUT FROM EACH SENSOR. THEN TERMINAL BLW OF THE A/C AMPLIFIER INPUTS CURRENT TO TERMINAL SIOF THE BLOWER MOTOR CONTROL RELAY IN CONFORMITY WITH THE REQUIRED VENT OUTPUT. THIS CURRENT ACTIVATES THEBLOWER MOTOR CONTROL RELAY SO THAT CURRENT FLOWS FROM TERMINAL M+ OF THE BLOWER MOTOR CONTROL RELAY →TERMINAL 2 OF BLOWER MOTOR → TERMINAL 1 → TERMINAL M– OF BLOWER MOTOR CONTROL RELAY → TERMINAL GND →GROUND, ACTIVATING THE BLOWER MOTOR. THE BLOWER MOTOR THEN OPERATES AT DIFFERENT STEPS IN CONFORMITY WITHVARIABLE CURRENT FLOW OUTPUT FROM TERMINAL BLW OF THE A/C AMPLIFIER TO TERMINAL SI OF THE BLOWER MOTORCONTROL RELAY.

2. OPERATION OF AIR INLET CONTROL SERVO MOTOR(SWITCHING FROM FRESH TO RECIRC)

WITH IGNITION SW TURNED ON, THE CURRENT FLOWS FROM HTR FUSE TO TERMINAL 2 OF AIR INLET CONTROL SERVO MOTOR→ TERMINAL 5 → TERMINAL AIR OF A/C AMPLIFIER → TERMINAL GND → GROUND, THE MOTOR ROTATES AND THE DAMPERSTOPS AT RECIRC POSITION.

(SWITCH(NG FROM RECIRC TO FRESH)

WITH IGNITION SW TURNED ON, THE CURRENT FLOWS FROM HTR FUSE TO TERMINAL 2 OF AIR INLET CONTROL SERVO MOTOR→ TERMINAL 3 → TERMINAL AIF OF A/C AMPLIFIER → TERMINAL GND → GROUND, THE MOTOR ROTATES AND THE DAMPERSTOPS AT FRESH POSITION.

3. OPERATION OF AIR VENT MODE CONTROL SERVO MOTORWITH IGNITION SW TURNED ON, THE CURRENT FLOWS FROM HTR FUSE TO TERMINAL IG OF A/C AMPLIFIER

(SWITCHING FROM DEF TO FACE)

THE CURRENT FROM TERMINAL AOF OF A/C AMPLIFIER → TERMINAL 1 OF AIR VENT MODE CONTROL SERVO MOTOR →TERMINAL 2 → TERMINAL AOD OF A/C AMPLIFIER → TERMINAL GND → GROUND. THE MOTOR ROTATES AND THE DAMPERMOVES TO FACE SIDE. WHEN THE DAMPER OPERATES WITH THE A/C SW AT FACE POSITION, THE DAMPER POSITION SIGNAL ISINPUT FROM TERMINAL 3 OF THE SERVO MOTOR TO THE TERMINAL TPO OF THE A/C AMPLIFIER. AS A RESULT, CURRENT TO THESERVO MOTOR CIRCUIT IS CUT OFF BY THE AMPLIFIER, SO THE DAMPER STOPS AT THAT POSITION.

(SWITCHING FROM FACE TO DEF)

THE CURRENT FLOWS FROM TERMINAL AOD OF A/C AMPLIFIER → TERMINAL 2 OF AIR VENT MODE CONTROL SERVO MOTOR →TERMINAL 1 → TERMINAL AOF OF A/C AMPLIFIER → TERMINAL GND → GROUND, THE MOTOR ROTATES AND THE DAMPER STOPSAT THAT POSITION.

4. OPERATION OF AIR MIX CONTROL SERVO MOTORWHEN THE TEMPERATURE SW IS TURNED TO THE “COOL” SIDE, THE CURRENT FLOWS FROM TERMINAL AMC OF A/C AMPLIFIER→ TERMINAL 1 OF AIR MIX CONTROL SERVO MOTOR → MOTOR → TERMINAL 2 → TERMINAL AMH OF A/C AMPLIFIER → TERMINALGND → GROUND AND THE MOTOR ROTATES. THE DAMPER OPENING ANGLE AT THIS TIME IS INPUT FROM TERMINAL 3 OF SERVOMOTOR TO TERMINAL TP OF A/C CONTROL ASSEMBLY, THIS IS USED TO DETERMINE THE DAMPER STOP POSITION AND MAINTAINTHE SET TEMPERATURE.

WHEN THE TEMPERATURE CONTROL SW IS TURNED TO THE “WARM” SIDE, THE CURRENT FLOWS FROM TERMINAL AMH OF A/CAMPLIFIER → TERMINAL 2 OF AIR MIX CONTROL SERVO MOTOR → MOTOR → TERMINAL 1 → TERMINAL AM1 OF A/C AMPLIFIER,ROTATING THE MOTOR IN REVERSE AND SWITCHING THE DAMPER FROM COOL TO WARM SIDE.

SYSTEM OUTLINE

229

5. AIR CONDITIONING OPERATIONTHE A/C AMPLIFIER RECEIVES VARIOUS SIGNALS, I.E., THE ENGINE RPM FROM THE IGNITER, OUTLET TEMPERATURE SIGNALFROM THE A/C THERMISTOR, COOLANT TEMPERATURE FROM THE ENGINE COOLANT TEMP. SENSOR (EFI WATER TEMP. SENSOR)AND THE LOCK SIGNAL FROM THE A/C COMPRESSOR, ETC.

WHEN THE ENGINE IS STARTED AND THE A/C SW (HEATER CONTROL SW) IS ON, A SIGNAL IS INPUT TO THE A/C AMPLIFIER. AS ARESULT, THE GROUND CIRCUIT IN A/C AMPLIFIER IS CLOSED AND CURRENT FLOWS FROM HTR FUSE TO TERMINAL 1 OF A/CMAGNETIC CLUTCH RELAY → TERMINAL 2 → TERMINAL ACMG OF ENGINE CONTROL MODULE (ENGINE ECU) → TERMINAL A/C →TERMINAL MGC OF A/C AMPLIFIER → TERMINAL GND → GROUND, TURNING THE RELAY ON, SO THAT THE A/C MAGNETIC CLUTCHIS ON AND THE A/C AMPLIFIER OPERATES.

AT THE SAME TIME, THE ENGINE CONTROL MODULE (ENGINE ECU) DETECTS THE MAGNETIC CLUTCH IS ON AND THE A/CAMPLIFIER IS OPERATING AND OPENS DIRECTION TO AVOID LOWERING THE ENGINE RPM DURING A/C OPERATING.

WHEN ANY OF THE FOLLOWING SIGNALS ARE INPUT TO THE A/C AMPLIFIER, THE A/C AMPLIFIER OPERATES TO TURN OFF THEAIR CONDITIONING.

∗ ENGINE RPM SIGNAL IS HIGH.

∗ COOLANT TEMP. SIGNAL IS HIGH.

∗ A SIGNAL THAT THE TEMPERATURE AT THE AIR OUTLET IS LOW.

∗ A SIGNAL THAT THERE IS A LARGE DIFFERENCE BETWEEN ENGINE SPEED AND COMPRESSOR SPEED.

∗ A SIGNAL THAT THE REFRIGERANT PRESSURE IS ABNORMALLY HIGH OR LOW.

Indicates related system.Indicates the wiring harness and wiring har-ness connector. The wiring harness with maleterminal is shown with arrowsOutside numerals are pin numbers.

is used to indicate different wiring and connector, etc. when the vehicle model, enginetype, or specification is different.Indicates a shielded cable.

Indicates and located on ground point.The same code occuring on the next pageindicates that the wire harness is continuous.

System TitleIndicates the wiring color.Wire colors are indicated by an alphabetical code.B = Black L = Blue R = RedBR = Brown LG= Light Green V = VioletG = Green O = Orange W = WhiteGR= Gray P = Pink Y = Yellow

The first letter indicates the basic wire color andthe second letter indicates the color of the stripe.

Indicates the connector to be connected to apart (the numeral indicates the pin No.)The position of the parts is the same as shownin the wiring diagram and wire routing.Indicates the pin number of the connector. The numbering system is different for femaleand male connectors.

The numbering system for the overall wiring dia-gram is the same as above.Indicates a Relay Block. No Shading is used andonly the Relay Block No. is shown to distinguishit from the J/B.
