HOW TO USE THIS MANUAL
This manual provides information on the electrical circuits installed on vehicles by
dividing them into each system circuit.
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 Wire Routing sections to find
each part, junction block and wiring harness connectors, wiring harness and wiring
harness connectors, splice points, and ground points of each system circuit. Internal
wiring for each junction block is also provided for better understanding of connection
within a junction block.
Wiring related to each system is indicated in each system circuit by arrows (from
, to ). When overall connections are required, see the Overall Wiring Diagram
at the end of this manual.

TROUBLESHOOTING
VOLTAGE CHECK
(a)
Establish conditions in which voltage is present at the
check point.
Example:
(b)
– Ignition SW on
– Ignition SW and SW 1 on
– Ignition SW, SW 1 and Relay on (SW 2 off)
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)
(b)
Disconnect the battery terminal or wire so there is no
voltage between the check points.
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.
(c)
10
Use the volt/ohmmeter with high impedance (10 kΩ/V
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.

ENGINE CONTROL (3S–GTE)
SYSTEM OUTLINE
THE ENGINE CONTROL SYSTEM UTILIZES A MICROCOMPUTER AND MAINTAINS OVERALL CONTROL OF THE ENGINE. ETC. AN
OUTLINE OF ENGINE CONTROL IS GIVEN HERE.
1. PTIS (INPUT SIGNALS)
(1) WATER TEMP. SIGNAL SYSTEM
THE ECTS (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 PCME (ECU).
(2) INTAKE AIR TEMP. SIGNAL SYSTEM
THE IATS (INTAKE AIR TEMP. SENSOR) IS INSTALLED INSIDE THE AFS (AIR FLOW METER) AND DETECTS THE INTAKE AIR TEMP.,
WHICH IS INPUT AS A CONTROL SIGNAL TO TERMINAL THA OF THE PCME (ECU).
(3) OXYGEN DENSITY SIGNAL SYSTEM
THE OXYGEN DENSITY IN THE EXHAUST EMISSIONS IS DETECTED AND INPUT AS A CONTROL SIGNAL TO TERMINAL OX OF
THE PCME (ECU). TO MAINTAIN STABLE DETECTION PERFORMANCE BY THE HOZS (OXYGEN SENSOR), A HEATER IS USED
FOR WARMING THE SENSOR. THE HEATER IS ALSO CONTROLLED BY THE PCME (ECU) (HT).
(4) CRANKSHAFT POSITION SIGNAL SYSTEM
CRANKSHAFT POSITION AND ENGINE SPEED IS DETECTED BY THE PICK–UP COIL INSTALLED INSIDE THE DISTRIBUTOR.
CRANKSHAFT POSITION IS INPUT AS A CONTROL SIGNAL TO TERMINAL G1 AND G2 OF THE PCME (ECU), AND ENGINE SPEED
SIGNAL IS INPUT TO TERMINAL NE+.
(5) THROTTLE POSITION SIGNAL SYSTEM
THE THROTTLE POSITION SENSOR DETECTS THE THROTTLE VALVE OPENING ANGLE, WHICH IS INPUT AS A CONTROL
SIGNAL TO TERMINAL VTA OF THE PCME (ECU), OR WHEN THE VALVE IS FULLY CLOSED, TO TERMINAL IDL.
(6) VEHICLE SPEED SIGNAL SYSTEM
THE SPEED METER INSIDE THE COMBINATION METER SENDS A VEHICLE SPEED SIGNAL TO TERMINAL SPD OF THE PCME
(ECU) AS A CONTROL SIGNAL.
(7) ACS (A/C SW) SIGNAL SYSTEM
THE OPERATING VOLTAGE OF THE A/C MAGNETIC CLUTCH IS DETECTED AND INPUT IN THE FORM OF A CONTROL SIGNAL TO
TERMINAL AC OF THE PCME (ECU).
(8) BATTERY SIGNAL SYSTEM
VOLTAGE IS CONSTANTLY APPLIED TO TERMINAL BATT OF THE PCME (ECU). WHEN THE IGNITION SW IS TURNED TO ON,
VOLTAGE FOR PCME (ECU) OPERATION IS APPLIED VIA THE EFI MAIN RELAY TO TERMINALS +B AND +B1 OF THE ECU.
(9) 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 PCME (ECU).
(10) STOP LIGHT SW SIGNAL SYSTEM
THE STOP LIGHT SW IS USED TO DETECT WHETHER OR NOT THE VEHICLE IS BRAKING AND THE INFORMATION IS INPUT AS A
CONTROL SIGNAL TO TERMINAL STP OF THE PCME (ECU).
(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 PCME (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
PCME (ECU).
(13) ELECTRICAL LOAD SIGNAL SYSTEM
THE SIGNAL WHEN SYSTEMS SUCH AS THE REAR WINDOW DEFOGGER, HEADLIGHTS, ECT. WHICH CAUSE A HIGH
ELECTRICAL BURDEN ARE ON IS INPUT TO TERMINAL ELS AS A CONTROL SIGNAL.
58
2. CONTROL SYSTEM
* SMPI (EFI, ELECTRONIC FUEL INJECTION) SYSTEM
THE SMPI (EFI) SYSTEM MONITORS THE ENGINE REVOLUTIONS THROUGH THE SIGNALS EACH SENSOR (INPUT SIGNALS (1) TO
(12)) INPUTS TO THE PCME (ECU). BASED ON THIS DATA AND THE PROGRAM MEMORIZED IN THE PCME (ECU), THE MOST
APPROPRIATE FUEL INJECTION TIMING IS DECIDED AND CURRENT IS OUTPUT TO TERMINALS #1, #2, #3 AND #4 OF THE PCME
(ECU), CAUSING THE INJECTORS TO OPERATE IT (TO INJECT FUEL). IT IS THIS SYSTEM WHICH, THROUGH THE WORK OF THE
PCME (ECU), FINELY CONTROLS FUEL INJECTION IN RESPONSE TO DRIVING CONDITIONS.
* EI (ESA, ELECTRONIC SPARK ADVANCE) SYSTEM
THE EI (ESA) SYSTEM MONITORS THE ENGINE REVOLUTIONS USING THE SIGNALS (INPUT SIGNALS (1, 2, 4, 5, 6, 9, 11, 12)) INPUT
TO THE PCME (ECU) FROM EACH SENSOR. BASED ON THIS DATA AND THE PROGRAM MEMORIZED IN THE PCME (ECU), THE
MOST APPROPRIATE IGNITION TIMING IS DECIDED AND CURRENT IS OUTPUT TO TERMINAL IGT OF THE PCME (ECU). THIS
OUTPUT CONTROLS THE IGNITER TO PRODUCE THE MOST APPROPRIATE IGNITION TIMING FOR THE DRIVING CONDITIONS.
* FUEL PUMP CONTROL SYSTEM
THE PCME (ECU) OPERATION OUTPUTS TO TERMINAL FPR AND CONTROLS THE FUEL PUMP RELAY AND THUS CONTROLS THE
FUEL PUMP DRIVE SPEED IN RESPONSE TO CONDITIONS.
* HOZS (OXYGEN SENSOR) HEATER CONTROL SYSTEM
THE HOZS (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 HOZS (OXYGEN SENSOR) TO IMPROVE DETECTION PERFORMANCE
OF THE SENSOR. THE PCME (ECU) EVALUATES THE SIGNALS FROM EACH SENSOR (INPUT SIGNALS (1, 4, 8, 9, 11)), CURRENT IS
OUTPUT TO TERMINAL HT AND CONTROLS THE HEATER.
* ISC (IDLE SPEED CONTROL) SYSTEM
THE ISC SYSTEM (ROTARY SOLENOID TYPE) INCREASES ENGINE SPEED 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 PCME (ECU)
EVALUATES THE SIGNALS FROM EACH SENSOR (INPUT SIGNALS 1, 4 TO 9, 13)), OUTPUTS CURRENT TO TERMINALS RSC AND
RSO AND CONTROLS THE IACV (ISC VALVE).
* EGR CONTROL SYSTEM
WITH THE EGR CONTROL SYSTEM, THE PCME (ECU) EVALUATES THE (INPUT SIGNALS (1, 4, 5, 9)) FROM EACH SENSOR,
CURRENT IS OUTPUT TO TERMINAL EGR AND OPERATION OF THE VSV (FOR EGR) IS CONTROLLED.
* INTAKE AIR CONTROL SYSTEM
IN THE INTAKE AIR CONTROL SYSTEM, EACH CYLINDER IN THE INTAKE MANIFOLD IS DIVIDED INTO TWO PARTS, WITH AN INTAKE
AIR CONTROL VALVE INSTALLED IN THE PASSAGE ON ONE SIDE. THE OPENING AND CLOSING OF THE VALVE PROVIDES THE
MOST APPROPRIATE INTAKE AIR FLOW AND, AS WELL AS PREVENTING PERFORMANCE LOSS AT LOW SPEEDS, ALSO IMPROVES
FUEL ECONOMY. THE PCME (ECU) EVALUATES THE SIGNALS FROM EACH SENSOR (INPUT SIGNALS (4, 5, 9, 12)), OUTPUTS
CURRENT TO TERMINAL TVIS CONTROLS THE VSV (FOR T–VIS) AND, CARRIES OUT OPENING AND CLOSING OF THE VALVE.
3. DIAGNOSIS SYSTEM
WITH THE DIAGNOSIS SYSTEM, WHEN THERE IS A MALFUNCTION IN THE PCME (ECU) SIGNAL SYSTEM, THE MALFUNCTIONING
SYSTEM IS RECORDED IN THE MEMORY. THE MALFUNCTIONING 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 PCME (ECU) MEMORY OR ELSE STOPS THE ENGINE.

ENGINE CONTROL (5S–FE)
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. PTIS (INPUT SIGNALS)
(1) WATER TEMP. SIGNAL SYSTEM
THE ECTS (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 PCME (ECU).
(2) INTAKE AIR TEMP. SIGNAL SYSTEM
THE IATS (INTAKE AIR TEMP. SENSOR) IS DETECTS THE INTAKE AIR TEMP., WHICH IS INPUT AS A CONTROL SIGNAL TO
TERMINAL THA OF THE PCME (ECU).
(3) OXYGEN DENSITY SIGNAL SYSTEM
THE OXYGEN DENSITY IN THE EXHAUST EMISSIONS IS DETECTED AND INPUT AS A CONTROL SIGNAL TO TERMINAL OX1 AND
OX2 (CALIFORNIA) OF THE PCME (ECU).
(4) CRANKSHAFT POSITION SIGNAL SYSTEM
CRANKSHAFT POSITION AND ENGINE SPEED ARE DETECTED BY THE PICK–UP COIL INSTALLED INSIDE THE DISTRIBUTOR.
CRANKSHAFT POSITION IS INPUT AS A CONTROL SIGNAL TO TERMINAL G+, OF THE PCME (ECU), AND ENGINE SPEED SIGNAL
IS INPUT TO TERMINAL NE+.
(5) THROTTLE POSITION SIGNAL SYSTEM
THE THROTTLE POSITION SENSOR DETECTS THE THROTTLE VALVE OPENING ANGLE, WHICH IS INPUT AS A CONTROL
SIGNAL TO TERMINAL VTA OF THE PCME (ECU), OR WHEN THE VALVE IS FULLY CLOSED, TO TERMINAL IDL.
(6) VEHICLE SPEED SIGNAL SYSTEM
THE SPEED METER INSIDE THE COMBINATION METER SENDS A VEHICLE SPEED SIGNAL TO TERMINAL SPD OF THE PCME
(ECU) AS A CONTROL SIGNAL.
(7) NEUTRAL POSITION SIGNAL SYSTEM (A/T)
THE PNS (NEUTRAL START SW) DETECTS WHETHER THE SHIFT POSITION IS IN NEUTRAL AND PARKING OR NOT, AND INPUTS
A CONTROL SIGNAL TO TERMINAL NSW OF THE PCME (ECU).
(8) A/C SW SIGNAL SYSTEM
THE A/C AMPLIFIER INPUTS THE A/C OPERATIONS TO TARMINAL ACA OF THE PCME (ECU) AS A CONTROL SIGNAL.
(9) BATTERY SIGNAL SYSTEM
VOLTAGE IS CONSTANTLY APPLIED TO TERMINAL BATT OF THE PCME (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 PCME (ECU).
(10) INTAKE AIR VOLUME SIGNAL SYSTEM
INTAKE AIR VOLUME IS DETECTED BY THE MAP (VACUUM SENSOR) AND IS INPUT AS A CONTROL SIGNAL TO TERMINAL PIM
OF THE PCME (ECU).
(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 PCME (ECU).
(12) ELECTRICAL LOAD SIGNAL SYSTEM
THE SIGNAL WHEN SYSTEMS SUCH AS THE REAR WINDOW DEFOGGER, HEADLIGHTS, ETC. WHICH CAUSE A HIGH
ELECTRICAL BURDEN ARE ON IS INPUT TO TERMINAL ELS AS A CONTROL SIGNAL.
2. CONTROL SYSTEM
* MPI (EFI, ELECTRONIC FUEL INJECTION) SYSTEM
THE MPI (EFI) SYSTEM MONITORS THE ENGINE REVOLUTIONS THROUGH THE SIGNALS EACH SENSOR (INPUT SIGNALS (1) TO
(12)) INPUTS TO THE PCME (ECU). BASED ON THIS DATA AND THE PROGRAM MEMORIZED IN THE PCME (ECU), THE MOST
APPROPRIATE FUEL INJECTION TIMING IS DECIDED AND CURRENT IS OUTPUT TO TERMINALS #10 AND #20 OF THE PCME (ECU),
CAUSING THE INJECTORS TO OPERATE IT (TO INJECT FUEL). IT IS THIS SYSTEM WHICH, THROUGH THE WORK OF THE PCME
(ECU), FINELY CONTROLS FUEL INJECTION IN RESPONSE TO DRIVING CONDITIONS.
DURING ENGINE CRANKING (SIGNAL INPUT TO TERMINAL STA) OR FOR APPLOX. 2 SECONDS AFTER NE SIGNAL INPUT, PCME
(ECU) OPERATION ENERGIZES (POINT CLOSED) THE FUEL PUMP CIRCUIT INSIDE THE CIRCUIT OPENING RELAY, CAUSING THE
FUEL PUMP TO OPERATE.
70
* EI (ESA, ELECTRONIC FUEL ADVANCE)
THE EI (ESA) SYSTEM MONITORS THE ENGINE REVOLUTIONS USING THE SIGNALS (INPUT SIGNALS (1, 4, 5, 10, 11)) INPUT TO
THE PCME (ECU) FROM EACH SENSOR. BASED ON THIS DATA AND THE PROGRAM MEMORIZED IN THE PCME (ECU), THE MOST
APPROPRIATE IGNITION TIMING IS DECIDED AND CURRENT IS OUTPUT TO TERMINAL IGT OF THE PCME ECU. THIS OUTPUT
CONTROLS THE IGNITER TO PRODUCE THE MOST APPROPRIATE IGNITION TIMING FOR THE DRIVING CONDITIONS.
* ISC (IDLE SPEED CONTROL) SYSTEM
THE ISC SYSTEM INCREASES ENGINE SPEED 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 PCME (ECU) EVALUATES THE SIGNALS FROM
EACH SENSOR (INPUT SIGNALS (1, 4 TO 8, 11, 12)), OUTPUTS CURRENT TO TERMINALS ISCO AND ISCC, AND CONTROLS THE ISC
VALVE.
* EGR CONTROL SYSTEM
THE EGR CUT CONTROL SYSTEM CONTROLS THE VSV (FOR EGR) BY EVALUATING THE SIGNALS FROM EACH SENSOR INPUT TO
THE PCME (ECU) (INPUT SIGNALS (1, 4, 10)) AND BY SENDING OUTPUT TO TERMINAL EGR OF THE PCME (ECU).
* A/C CUT CONTROL SYSTEM
WHEN THE VEHICLE SUDDENLY ACCELERATES FROM LOW ENGINE SPEED, THIS SYSTEM CUTS OFF AIR CONDITIONER
OPERATION FOR A FIXED PERIOD OF TIME IN RESPONSE TO THE VEHICLE SPEED AND THROTTLE VALVE OPENING ANGLE IN
ORDER TO MAINTAIN ACCELERATION PERFORMANCE.
THE PCME (ECU) RECEIVES INPUT SIGNALS (5, 6), AND OUTPUTS SIGNALS TO TERMINAL ACT.
* FUEL PRESSURE CONTROL SYSTEM
THE FUEL PRESSURE UP SYSTEM CAUSES THE VSV (FOR FUEL PRESSURE UP) TO COME ON FOR HIGH TEMP. STARTS IN
ORDER TO INCREASE THE FUEL PRESSURE, IMPROVE STARTABILITY AT HIGH TEMPERATURES AND PROVIDE STABLE IDLING.
THE PCME (ECU) EVALUATES THE INPUT SIGNALS FROM EACH SENSOR (1, 2, 5, 11), OUTPUT CURRENT TO TERMINAL FPU AND
CONTROLS THE VSV.
3. DIAGNOSIS SYSTEM
WITH THE DIAGNOSIS SYSTEM, WHEN THERE IS A MALFUNCTION IN THE PCME (ECU) SIGNAL SYSTEM, THE MALFUNCTION
SYSTEM IS RECORDED IN THE MEMORY. THE MALFUNCTIONING 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 PCME (ECU) MEMORY OR ELSE STOPS THE ENGINE.

SYSTEM OUTLINE
WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS TO TERMINAL (A) 4 (CANADA), (F) 4 (USA) OF THE RETRACT CONTROL
REALY THROUGH ECU–IG FUSE.
VOLTAGE IS APPLIED AT ALL TIMES TO TERMINAL (A) 2 (CANADA), (F) 2 (USA) OF THE RETRACT CONTROL REALY. THROUGH THE
TAILLIGHT RELAY COIL, AND TO TERMINAL (A) 10 (CANADA), (F) 10 (USA) THROUGH THE HEADLIGHT RELAY COIL.
1. NORMAL LIGHTING OPERATION
<TURN TAILLIGHT ON>
WITH LIGHT CONTROL SW TURNED TO TAILLIGHT POSITION, A SIGNAL IS INPUT INTO TERMINAL (A) 13 (CANADA), (F) 13 (USA) OF
THE RETRACT CONTROL RELAY. ACCORDING TO THIS SIGNAL, THE CURRENT FLOWING TO TERMINAL (A) 2 (CANADA), (F) 2 (USA)
OF THE RELAY FLOWS FROM TERMINAL (A) 18 (CANADA), (F) 18 (USA) → 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) 13 (CANADA), (F) 13 (USA)
AND (A) 14 (CANADA), (F) 14 (USA) OF THE RETRACT CONTROL REALY. ACCORDING TO THIS SIGNAL, THE CURRENT FLOWING TO
TERMINAL (A) 10 (CANADA), (F) 10 (USA) OF THE RELAY FLOWS TO TERMINAL (A) 18 (CANADA), (F) 18 (USA) → TO GROUND IN THE
HEADLIGHT CIRCUIT, AND CAUSES TAILLIGHT 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 (A) 4 (CANADA), (F) 4 (USA) OF THE RELAY),
WHEN DOOR ON DRIVER’S SIDE IS OPENED (INPUT SIGNAL GOES TO TERMINAL (A) 15 (CANADA), (F) 15 (USA) OF THE RELAY), THE

HEADLIGHT AND FOG LIGHT (FOR CANADA)
SYSTEM OUTLINE
CURRENT FROM THE BATTERY FLOWS CONTINOUSLY FROM FL 2.0L → ALT FUSE → AM1 FUSE→ TALLIGHT RELAY (COIL SIDE) →
TERMINAL RT OF THE RETRACT CONTROL RELAY, FL 2.0L → ALT FUSE → AM1 FUSE → FOGLIGHT RELAY (COIL SIDE) → TERMINAL
RDRL OF RETRACT CONTROL RELAY.
WHEN THE IGNITION SW IS TURNED ON, THE CURRENT FLOWING THROUGH THE GAUGE FUSE TO TERMINAL IG OF THE RETRACT
CONTROL RELAY.
DAYTIME RUNNING LIGHT OPERATION
WHEN THE ENGINE IS STARTED, VOLTAGE IS GENERATED AT TERMINAL “L” OF THE ALTERNATOR AND VOLTAGE IS APPLIED TO
TERMINAL “L” OF THE RETRACT CONTROL 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 LIGHTS SYSTEM DOSE NOT OPERATE.
IF THE PARKING BRAKE LEVER IS THEN RELEASED (PARKING BRAKE SW OFF), THE SIGNAL IS INPUT TO TERMINAL ’PKB’ OF THE
RELAY.
THIS ACTIVATES THE RELAY AND CURRENT FROM ALT FUSE FLOWS TO TAILLIGHT RELAY (POINT SIDE) → TAIL FUSE → TAIL,
LICENCE AND FRONT CLEARANCE LIGHTS, ETC. → GROUND.
ALSO, CURRENT FROM ALT FUSE FLOWS TO FOG FUSE → FOG LIGHT RELAY (POINT SIDE) → FOG LIGHTS → GROUND, SO BOTH
TAIL AND FOG LIGHTS LIGHT UP. THIS IS HOW THE DAYTIME RUNNING LIGHTS SYSTEM OPERATES AND TAIL, FOG LIGHT HAVE
LIGHTED UP, THE TAIL AND FOG LIGHT 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 FOG LIGHTS REMAIN ON.
IF THE IGNITION SW IS THEN TURNED OFF, THE TAIL AND FOG LIGHTS ARE TURNED OFF.
IF THE ENGINE IS STARTED WHILE THE PARKING BRAKE IS RELEASED (PARKING BRAKE SW OFF), THE DAYTIME RUNNING LIGHTS
SYSTEM OPERATES AND THE TAIL AND FOG LIGHTS LIGHT UP AS THE ENGINE STARTS.

SYSTEM OUTLINE
CURRENT ALWAYS FLOWS TO TERMINAL 2 OF THE POWER MAIN RELAY THROUGH THE POWER FUSE. WITH THE IGNITION SW
TURNED ON, CURRENT FLOWS THROUGH THE GAUGE FUSE TO TERMINAL 3 OF THE POWER MAIN RELAY → TERMINAL 1 →
GROUND. THIS ACTIVATES THE RELAY AND CURRENT FLOWING TO TERMINAL 4 OF THE POWER MAIN RELAY → TERMINAL 9 OF
THE POWER WINDOW MASTER SW AND TERMINAL 5 OF THE POWER WINDOW SW RH (PASSENGER’S).
1. MANUAL OPERATION (DRIVER’S WINDOW)
WITH THE IGNITION SW TURNED ON AND THE POWER WINDOW MASTER SW IN UP POSITION, THE CURRENT FLOWING TO
TERMINAL 9 OF THE POWER WINDOW MASTER SW FLOWS TO TERMINAL 3 OF THE MASTER SW → TERMINAL 2 OF THE POWER
WINDOW MOTOR LH (DRIVER’S) → MOTOR → TERMINAL 1 → TERMINAL 4 OF THE MASTER SW → TERMINAL 6 → 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
4 OF THE MASTER SW CAUSES THE FLOW OF CURRENT FROM TERMINAL 1 OF THE MOTOR → MOTOR → TERMINAL 2 →
TERMINAL 3 OF THE MASTER SW → TERMINAL 6 → 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 DRIVER’S SW OF THE POWER WINDOW MASTER SW IN DOWN POSITION, CURRENT
FLOWING TO TERMINAL 9 OF THE MASTER SW FLOWS TO TERMINAL 4 OF THE MASTER SW → TERMINAL 1 OF THE POWER
WINDOW MOTOR → MOTOR → TERMINAL 2 → TERMINAL 3 OF THE MASTER SW → TERMINAL 6 → GROUND, CAUSING THE MOTOR
TO ROTATE TOWARDS THE DOWN SIDE. THEN THE SOLENOID IN THE MASTER SW IS ACTIVATED AND IT LOCKS THE DRIVER’S SW
BEING PUSHED, CAUSING THE MOTOR TO CONTINUE TO ROTATE IN AUTO DOWN OPERATION.
WHEN THE WINDOW HAS COMPLETELY DESCENDED, THE CURRENT FLOW BETWEEN TERMINAL 3 OF THE MASTER SW AND
TERMINAL 6 INCREASES. AS A RESULT, THE SOLENOID STOPS OPERATING, THE DRIVER’S SW TURNS OFF AND FLOW FROM
TERMINAL 9 OF THE MASTER SW TO TERMINAL 4 IS CUT OFF, STOPPING THE MOTOR SO THAT AUTO STOP OCCURS.
3. STOPPING OF AUTO DOWN AT DRIVER’S WINDOW
WHEN THE DRIVER’S SW 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 3 OF THE MASTER SW → TO TERMINAL 6, SO THE MOTOR STOPS,
CAUSING AUTO DOWN OPERATION TO STOP. IF THE DRIVER’S SW IS PUSHED CONTINUOUSLY, THE MOTOR ROTATES IN THE
UPWARD 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 1 OF THE POWER WINDOW SW → TERMINAL 2 OF THE WINDOW MOTOR → MOTOR →
TERMINAL 1 → TERMINAL 4 OF THE POWER WINDOW SW → TERMINAL 3 → TERMINAL 7 OF THE MASTER SW → TERMINAL 6 →
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, FLOM TERMINAL 1 → MOTOR → 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 9 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.
5. KEY OFF POWER WINDOW OPERATION
WITH THE IGNITION SW TURNED FROM ON TO OFF, THE DOOR LOCK ECU OPERATES AND CURRENT FLOWS FROM POWER FUSE

WITH IGNITION KEY IN CYLINDER (UNLOCK WARNING SW ON), WHEN THE DOOR IS OPENED AND LOCKED USING DOOR LOCK
KNOB (DOOR LOCK MOTOR), THE DOOR IS LOCKED ONCE BUT EACH DOOR IS UNLOCKED SOON BY THE FUNCTION OF THE ECU.
AS A RESULT, THE CURRENT FLOWS FROM TERMINAL 8 OF THE ECU → TERMINAL 3 → TERMINAL (A)2 (LH), (A)3 (RH) (W/ THEFT
DETERRENT), (B)2 (W/O THEFT DETERRENT) OF THE DOOR LOCK MOTORS → TERMINAL (A)5 (LH), (A)6 (RH) (W/ THEFT
DETERRENT), (B)4 (W/O THEFT DETERRENT) → TERMINAL 4 OF THE ECU → TERMINAL 16 → TO GROUND AND CAUSES ALL THE
DOORS TO UNLOCK.
∗ OPERATING DOOR LOCK CONTROL SW OR DOOR LOCK KEY SW
WITH IGNITION KEY IN CYLINDER (UNLOCK WARNING SW ON), WHEN THE DOOR IS OPENED AND LOCKED USING DOOR LOCK
CONTROL SW OR KEY SW, THE DOOR IS LOCKED ONCE BUT EACH DOOR IS UNLOCK BY THE FUNCTION OF SW CONTAINED IN
MOTORS, WHICH THE SIGNAL IS INPUT TO TERMINAL 6 (DRIVER’S) OR 5 (PASSENGER’S) OF THE ECU. ACCORDING TO THIS INPUT
SIGNAL, THE CURRENT IN THE ECU FLOWS FROM TERMINAL 8 OF THE ECU → TERMINAL 3 → TERMINAL (A)2 (LH), (A)3 (RH) (W/
THEFT DETERRENT), (B)2 (W/O THEFT DETERRENT) OF THE DOOR LOCK MOTORS → TERMINAL (A)5 (LH), (A)6 (RH) (W/ THEFT

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 trouble codes become
the most important source of information when troubleshooting.
When troubleshooting the airbag system, always inspect the diagnostic trouble codes before disconnecting
the battery.
Work must be started after 30 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 30 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 canceled. 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.
When the vehicle has tilt and telescopic steering, power seat, outside rear view mirror and power shoulder
belt anchorage, which are all equipped with memory function, it is not possible to make a record of the memory
contents. So when the operation is finished, it will be necessary to explain this fact to the customer, and
request the customer to adjust the features and reset the memory.
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 SRS 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. 10kΩ/V) tester.
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.

SRS AIRBAG
The airbag system has connectors which possess the functions described below:
1. AIRBAG ACTIVATION PREVENTION MECHANISM
Each connector contains a short spring plate. When the
connector is disconnected, the short spring plate
automatically connects the power source and grounding
terminals of the squib to preclude a potential difference
between the terminals.
2. ELECTRICAL CONNECTION CHECK MECHANISM
This mechanism is designed to electrically check if
connectors are connected correctly and completely.
The electrical connection check mechanism is designed so
that the connection detection pin connects with the
diagnosis terminals when the connector housing lock is in
the locked condition.
126
3. CONNECTOR TWIN–LOCK MECHANISM
With this mechanism connectors (male and female
connectors) are locked by two locking devices to increase
connection reliability. If the primary lock is incomplete, ribs
interfere and prevent the secondary lock.

SYSTEM OUTLINE
THE SRS (SUPPLEMENTAL RESTRAINT SYSTEM) AIRBAG IS A DRIVER PROTECTION DEVICE WHICH HAS A SUPPLEMENTAL ROLE
TO THE SEAT BELTS.
CURRENT FLOWS CONSTANTLY TO TERMINAL (A) 4 OF THE CENTER AIRBAG SENSOR ASSEMBLY. WHEN THE IGNITION SW IS
TURNED TO ACC OR ON, CURRENT FROM THE RAD & CIG FUSE FLOWS TO TERMINAL (A) 3 OF THE CENTER AIRBAG SENSOR
ASSEMBLY. ONLY WHEN THE IGNITION SW IS ON DOES THE CURRENT FROM THE GAUGE FUSE FLOW TO TERMINAL (A) 1. AND
THE CURRENT FROM THE AM1 FUSE TO TERMINAL (A) 2.
IF AN ACCIDENT OCCURS WHILE DRIVING, DECELERATION CAUSED BY A FRONTAL IMPACT IS DETECTED BY EACH SENSOR, AND
SWITCH, AND WHEN THE FRONTAL IMPACT EXCEEDS A SET LEVEL (WHEN THE MERCURY SW BUILT INTO THE CENTER AIRBAG
SENSOR ASSEMBLY IS ON AND THE CENTER AIRBAG SENSOR IS ON, FRONT AIRBAG SENSORS ARE OFF), CURRENT FROM THE
RAD & CIG, GAUGE OR AM1 FUSE FLOW TO TERMINAL (A) 8 OF THE CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 1 OF THE
AIRBAG SQUIB → SQUIB → TERMINAL 2 → TERMINALS (A) 7 OF CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL (A) 5,
TERMINAL (A) 10 OR BODY GROUND → GROUND.
WHEN THE MERCURY SW BUILT INTO THE CENTER AIRBAG SENSOR ASSEMBLY IS ON AND THE FRONT AIRBAG SENSOR LH OR
RH IS ON, CENTER AIRBAG SENSOR IS OFF CURRENT FROM THE RAD & CIG, GAUGE OR AM1 FUSE FLOWS TO TERMINALS (A) 8
OF THE CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 1 OF THE AIRBAG SQUIB → SQUIB → TERMINAL 2 → TERMINALS (A) 7
OF THE CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL (C) 1 OR (B) 2 → TERMINAL 1 OF FRONT AIRBAG SENSOR → TERMINAL
2 → TERMINAL (C) 2 OR (B) 1 OF CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL (A) 5, TERMINAL (A) 10 OR BODY GROUND →
GROUND.
WHEN THE MERCURY SW BUILT INTO THE CENTER AIRBAG SENSOR ASSEMBLY IS ON, AND THE FRONT AIRBAG SENSOR LH OR
RH IS ON AND CENTER AIRBAG SENSOR IS ON ONE OF THE ABOVE–MENTIONED CIRCUITS IS ACTIVATED SO THAT CURRENT
FLOWS TO THE AIRBAG SQUIB AND CAUSES IT TO OPERATE. THE BAG STORED INSIDE THE STEERING WHEEL PAD IS
INSTANTANEOUSLY EXPANDED TO SOFTEN THE SHOCK TO THE DRIVER.
THE REASON WHY THERE ARE MULTIPLE POWER SOURCES AND GROUND POINTS IS SO THAT IN THE EVENT THAT ONE OR TWO
OF THE POWER SOURCES AND GROUND POINTS DO NOT WORK FOR SOME REASON, THE REMAINING POWER SOURCE AND
GROUND POINT WILL BE AVAILABLE TO COMPENSATE.

EHPS (ELECTRO HYDRAULIC POWER STEERING)
SYSTEM OUTLINE
THE EHPS (ELECTRO HYDRAULIC POWER STEERING) SYSTEM FUNCTIONS TO CHANGE THE FORCE REQUIRED FOR STEERING
MANEUVERS, AND THEREBY PROVIDE THE IDEAL STEERING FEELING FOR AT VEHICLE SPEEDS AND STEERING CONDITIONS.
THIS IS DONE BY THE POWER STEERING ECU CONTROLLING THE HYDRAULIC PRESSURE ACTING UPON THE HYDRAULIC
REACTION CHAMBER (LOCATED IN THE GEAR BOX CONTROL UNIT) BY REGULATING THE POWER STEERING MOTOR’S SPEED
(AND HENCE THE AMOUNT OF FLUID FLOW).
EHPS OPERATION
WHEN THE IGNITION SWITCHED ON, STARTING CURRENT FLOWS FROM THE GAUGE FUSE TO TERMINAL IGB OF THE POWER
STEERING ELECTRONIC CONTROL UNIT, TERMINAL VS OF THE STEERING POSITION SENSOR, AND TERMINAL (A) 4 OF THE
POWER STEERING DRIVER.
THE VEHICLE SPEED IS DETECTED AT THE SPEED SENSOR, AND SIGNALS ARE INPUT AS CONTROL SIGNALS TO TERMINAL SPD
OF THE POWER STEERING ELECTRONIC CONTROL UNIT AND TO TERMINALS SS1 AND SS2 OF THE POWER STEERING
ELECTRONIC CONTROL UNIT.
WHEN THE ENGINE IS STARTED, SIGNALS ARE INPUT TO TERMINAL EFI OF THE POWER STEERING ELECTRONIC CONTROL UNIT
FROM THE ENGINE OF TERMINAL PSCT OF THE ENGINE AND ECT ECU. AS A RESULT, THE CURRENT APPLIED TO TERMINAL IGB
OF THE POWER STEERING ECU FROM THE GAUGE FUSE FLOWS FROM TERMINAL MRLY OF THE POWER STEERING ECU →
TERMINAL (B) 1 OF THE POWER STEERING RELAY → TERMINAL (B) 2 → GROUND, AND THE POWER STEERING RELAY IS
SWITCHED ON. AS A RESULT, THE CURRENT APPLIED TO TERMINAL (A) 1 OF THE POWER STEERING RELAY FROM THE ABS FUSE
FLOWS FROM TERMINAL (A) 2 OF THE POWER STEERING RELAY → TERMINAL (B) 1 OF THE POWER STEERING DRIVER AND TO
TERMINAL (A) 1 OF THE POWER STEERING MOTOR.
IF THE VEHICLE SPEED IS LOW, THE SPEED OF THE POWER STEERING MOTOR IS INCREASED BY INCREASING THE VOLTAGE OF
THE CURRENT THAT FLOWS FROM TERMINAL (A) 1 OF THE POWER STEERING MOTOR TO TERMINAL (A) 2 OF THE POWER
STEERING MOTOR → TERMINAL (B) 2 OF THE POWER STEERING DRIVER → TERMINAL (C) 2 → GROUND, WITH THE RESULT THAT
THE VOLUME OF FLOW OF THE POWER STEERING FLUID BECOMES GREATER, THUS PROVIDING A LIGHT STEERING FEELING.
WHEN THE VEHICLE SPEED IS HIGH, THE SPEED OF THE POWER STEERING MOTOR DECREASES AS A RESULT OF THE REDUCED
VOLTAGE APPLIED TO THE POWER STEERING MOTOR, AND THUS THE VOLUME OF FLOW OF THE POWER STEERING FLUID IS
REDUCED, SO THE STEERING FEELING IS MORE RESISTANT.

SYSTEM OUTLINE
WHEN THE IGNITION SW IS TURNED TO ACC POSITION THE CURRENT FROM THE CIG RADIO AND CIG FUSE FLOWS TO TERMINAL
3 OF THE SHIFT LOCK ECU. IN THE ON POSITION, THE CURRENT FROM THE ECU–IG FUSE FLOWS TO TERMINAL 4 OF THE ECU.
1. SHIFT LOCK MECHANISM
WITH THE IGNITION SW ON, WHEN A SIGNAL THAT THE BRAKE PEDAL IS DEPRESSED (STOP LIGHT SW ON) AND A SIGNAL THAT
THE SHIFT LEVER IS PUT IN “P” RANGE (CONTINUITY BETWEEN P1 AND P OF THE SHIFT POSITION SW) IS INPUT TO THE ECU. THE
ECU OPERATES AND CURRENT FLOWS FROM TERMINAL 4 OF THE ECU → TERMINAL SL+ OF THE SHIFT LOCK SOLENOID →
SOLENOID → TERMINAL SL– → TERMINAL 1 OF THE ECU → GROUND. THIS CAUSES THE SHIFT LOCK SOLENOID TO TURN ON
(PLATE STOPPER DISENGAGES) AND THE SHIFT LEVER CAN SHIFT INTO OTHER RANGE THAN THE “P” RANGE.
2. KEY INTERLOCK MECHANISM
WITH THE IGNITION SW IN ON OR ACC POSITION, WHEN THE SHIFT LEVER IS PUT IN “P” RANGE (NO CONTINUITY BETWEEN P2
AND P OF LOCK CONTROL SW), THE CURRENT FLOWING FROM TERMINAL 2 OF THE ECU → KEY INTERLOCK SOLENOID IS CUT
OFF. THIS CAUSES THE KEY INTERLOCK SOLENOID TO TURN OFF (LOCK LEVER DISENGAGES FROM LOCK POSITION) AND THE
IGNITION KEY CAN BE TURNED FROM ACC TO LOCK POSITION. IF THE IGNITION IS LEFT IN ACC OR ON POSITION WITH THE SHIFT
LEVER IN OTHER THAN “P” RANGE, THEN AFTER APPROX. ONE HOUR THE ECU OPERATES TO RELEASE THE LOCK.

SYSTEM OUTLINE
THIS SYSTEM CONTROLS THE RESPECTIVE BRAKE FLUID PRESSURES ACTING ON THE DISC BRAKE CYLINDERS OF THE RIGHT
FRONT WHEEL, LEFT FRONT WHEEL 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 SIGNALS
(1) SPEED SENSOR SIGNAL
THE SPEED OF THE WHEELS IS DETECTED AND INPUT TO TERMINALS FL+, FR+, RL+ AND RR+ OF THE ABS ECU.
(2) STOP LIGHT SW SIGNAL
A SIGNAL IS INPUT TO TERMINAL STP OF THE ABS ECU WHEN THE BRAKE PEDAL IS OPERATED.
(3) PARKING BRAKE SW SIGNAL
A SIGNAL IS INPUT TO TERMINAL PKB OF THE ABS ECU WHEN THE PARKING BRAKE IS OPERATED.
2. SYSTEM OPERATION
DURING SUDDEN BRAKING THE ABS ECU, WHICH HAS SIGNALS INPUT FROM EACH SENSOR, CONTROLS THE CURRENT FLOWING
TO THE SOLENOID INSIDE THE ACTUATOR AND LETS THE HYDRAULIC PRESSURE ACTING ON EACH WHEEL CYLINDER ESCAPE TO
THE RESERVOIR.
THE PUMP INSIDE THE ACTUATOR IS ALSO OPERATING AT THIS TIME AND IT RETURNS THE 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 CURRENT
ACTING ON THE SOLENOID IS CONTROLLED AND THE HYDRAULIC PRESSURE IS INCREASED. HOLDING OF THE HYDRAULIC
PRESSURE IS ALSO CONTROLLED BY THE ECU IN THE SAME METHOD AS ABOVE. BY REPEATED PRESSURE REDUCTION,
HOLDING AND INCREASE ARE REPEATED TO MAINTAIN VEHICLE STABILITY AND TO IMPROVE STEERABILITY DURING SUDDEN
BRAKING.

SYSTEM OUTLINE
THIS SYSTEM ELECTRONICALLY CONTROLS THE GEAR SHIFT TIMING, LOCK–UP TIMING, THE CLUTCH AND BRAKE HYDRAULIC
PRESSURE, AND THE ENGINE TORQUE DURING SHIFTING, TO ACHIVE OPTIMUM SHIFT FEELING.
IN ACCORDANCE TO THE VEHICLE DRIVING CONDITIONS AND ENGINE OPERATING CONDITIONS AS DETECTED BY VARIOUS
SENSORS.
1. GEAR SHIFT OPERATION
DURING DRIVING, THE PCME (ENGINE AND ECT ECU) SELECTS THE SHIFT FOR EACH GEAR WHICH IS MOST APPROPRIATE TO
THE DRIVING CONDITIONS, BASED ON INPUT SIGNALS FROM THE ECTS (EFI WATER TEMP. SENSOR) TO TERMINAL THW OF THE
PCME (ENGINE AND ECT ECU), AND ALSO THE INPUT SIGNALS TO TERMINAL SP2 OF THE PCME (ENGINE AND ECT ECU) FROM
THE SPEED SENSOR DEVOTED TO THE ECT. CURRENT IS THEN OUTPUT TO THE ECT SOLENOIDS. WHEN SHIFTING TO 1ST SPEED,
CURRENT FLOWS FROM TERMINAL S1 OF THE PCME (ENGINE AND ECT ECU) → TERMINAL 3 OF THE ECT SOLENOIDS → GROUND,
AND CONTINUITY FLOW TO NO.1 SOLENOID CAUSES THE SHIFT.
FOR 2ND SPEED, CURRENT FLOWS FROM TERMINAL S1 OF THE PCME (ENGINE AND ECT ECU) → TERMINAL 3 OF THE ECT
SOLENOIDS → GROUND, AND FROM TERMINAL S2 OF THE PCME (ENGINE AND ECT ECU) → TERMINAL 1 OF THE ECT SOLENOIDS
→ GROUND, AND CONTINUITY TO SOLENOIDS NO. 1 AND NO. 2 CAUSE THE SHIFT.
FOR 3RD SPEED, THERE IS NO CONTINUITY TO NO. 1 SOLENOID, ONLY TO NO. 2, CAUSING THE SHIFT.
SHIFTING INTO 4TH SPEED (OVER DRIVE) TAKES PLACE WHEN THERE IS NO CONTINUITY TO EITHER NO. 1 OR NO. 2 SOLENOID.
2. LOCK–UP OPERATION
WHEN THE PCME (ENGINE AND ECT ECU) JUDGES FROM EACH SIGNAL THAT LOCK–UP OPERATION CONDITIONS HAVE BEEN MET,
CURRENT FLOWS FROM TERMINAL SL OF THE PCME (ENGINE AND ECT ECU) → TERMINAL 2 OF THE ETC SOLENOIDS →
GROUND, CAUSING A CONTINUITY TO THE TCC (LOCK–UP SOLENOID) AND CAUSING LOCK–UP OPERATION.
3. STOP LIGHT SW CIRCUIT
IF THE BRAKE PEDAL IS DEPRESSED (STOP LIGHT SW ON) WHEN DRIVING IN LOCK–UP CONDITION, A SIGNAL IS INPUT TO
TERMINAL B/K OF THE PCME (ENGINE AND ECT ECU), THE PCME (ENGINE AND ECT ECU) OPERATES AND CONTINUITY TO THE
TCC (LOCK–UP SOLENOID) IS CUT.
4. OVERDRIVE CIRCUIT
* O/D MAIN SW ON
WHEN THE O/D MAIN SW IS TURNED ON (O/D OFF INDICATOR LIGHT TURNS OFF), A SIGNAL IS INPUT TO TERMINAL OD2 OF THE
PCME (ENGINE AND ECT ECU) AND PCME (ENGINE AND ECT ECU) OPERATION CAUSES GEAR SHIFT WHEN THE CONDITIONS
FOR OVERDRIVE ARE MET.
* O/D MAIN SW OFF
WHEN THE OVERDRIVE SW IS TURNED OFF, THE CURRENT FLOWING THROUGH THE O/D OFF INDICATOR LIGHT FLOWS
THROUGH THE O/D MAIN SW TO GROUND, CAUSING THE INDICATOR LIGHT TO LIGHT UP. AT THE SAME TIME, A SIGNAL IS INPUT
TO TERMINAL OD2 OF THE PCME (ENGINE AND ECT ECU) AND PCME (ENGINE AND ECT ECU) OPERATION PREVENTS SHIFT
INTO OVERDRIVE.

CRUISE CONTROL
SYSTEM OUTLINE
CURRENT IS APPLIED AT ALL TIMES THROUGH STOP FUSE TO TERMINAL 1 OF THE CRUISE CONTROL ECU AND TERMINAL 2 OF
STOP LIGHT SWITCH.
WITH THE IGNITION SWITCH TURNED ON, THE CURRENT FLOWS THROUGH THE GAUGE FUSE TO TERMINAL (A)4 OF THE CRUISE
CONTROL INDICATOR LIGHT. THE CURRENT THROUGH ECU–IG FUSE FLOWS TO TERMINAL 14 OF THE CRUISE CONTROL ECU.
WHEN THE IGNITION SWITCH IS ON AND THE CRUISE CONTROL MAIN SWITCH IS TURNED ON, A SIGNAL IS INPUT FROM TERMINAL
15 OF CRUISE CONTROL MAIN SWITCH TO TERMINAL 4 OF THE CRUISE CONTROL ECU. AS A RESULT, THE CRUISE CONTROL ECU
FUNCTIONS AND THE CURRENT TO TERMINAL 14 OF THE CRUISE CONTROL ECU FLOWS TO TERMINAL 13 OF THE CRUISE
CONTROL 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 FROM TERMINAL (A)4 OF THE CRUISE CONTROL
INDICATOR LIGHT → TERMINAL (B)11 → TERMINAL 5 OF THE CRUISE CONTROL ECU → TERMINAL 13 → GROUND, CAUSING THE
CRUISE CONTROL INDICATOR LIGHT TO LIGHT UP, INDICATING THAT CRUISE CONTROL IS READY FOR OPERATION.
1. SET OPERATION
WHEN THE CRUISE CONTROL MAIN SWITCH IS TURNED ON AND THE SET SWITCH 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 4 OF THE CRUISE CONTROL
ECU AND THE VEHICLE SPEED AT THE TIME THE SET SWITCH IS RELEASED IS MEMORIZED IN THE ECU AS THE SET SPEED.
2. SET SPEED CONTROL
DURING CRUISE CONTROL DRIVING, THE ECU COMPARES THE SET SPEED MEMORIZED IN THE ECU WITH THE ACTUAL VEHICLE
SPEED INPUT INTO TERMINAL 20 OF THE CRUISE CONTROL ECU FROM THE COMBINATION METER, AND CONTROLS THE CRUISE
CONTROL ACTUATOR TO MAINTAIN THE SET SPEED.
WHEN THE ACTUAL SPEED IS LOWER THAN THE SET SPEED, THE ECU CAUSES THE CURRENT TO THE CRUISE CONTROL
ACTUATOR TO FLOW FROM TERMINAL 12 → TERMINAL 6 OF THE CRUISE CONTROL ACTUATOR → TERMINAL 7 → TERMINAL 11 OF
CRUISE CONTROL ECU. AS A RESULT, THE MOTOR IN THE CRUISE CONTROL ACTUATOR IS ROTATED TO OPEN THE THROTTLE
VALVE AND THE THROTTLE CABLE IS PULLED TO INCREASE THE VEHICLE SPEED. WHEN THE ACTUAL DRIVING SPEED IS HIGHER
THAN THE SET SPEED, THE CURRENT TO CRUISE CONTROL ACTUATOR FLOWS FROM TERMINAL 11 OF ECU → TERMINAL 7 OF
CRUISE 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 THE
THROTTLE CABLE TO DECREASE THE VEHICLE SPEED.
3. COAST CONTROL
DURING CRUISE CONTROL DRIVING, WHILE THE COAST SWITCH IS ON, THE CRUISE CONTROL ACTUATOR RETURNS THE
THROTTLE CABLE TO CLOSE THE THROTTLE VALVE AND DECREASE THE DRIVING SPEED. THE VEHICLE SPEED WHEN THE COAST
SWITCH IS TURNED OFF IS MEMORIZED AND THE VEHICLE CONTINUES AT THE NEW SET SPEED.
4. ACCEL CONTROL
DURING CRUISE CONTROL DRIVING, WHILE THE ACCEL SWITCH IS TURNED ON, THE CRUISE CONTROL ACTUATOR PULLS THE
THROTTLE CABLE TO OPEN THE THROTTLE VALVE AND INCREASE THE DRIVING SPEED. THE VEHICLE SPEED WHEN THE ACCEL
SWITCH IS TURNED OFF IS MEMORIZED AND THE VEHICLE CONTINUES AT THE NEW SET SPEED.
5. RESUME CONTROL
UNLESS THE VEHICLE SPEED FALLS BELOW THE MINIMUM SPEED LIMIT (APPROX. 40 KM/H), AFTER CANCELING THE SPEED BY
THE CANCEL SWITCH, PUSHING THE RESUME SWITCH WILL CAUSE THE VEHICLE TO RESUME THE SPEED SET BEFORE
CANCELLATION.
6. MANUAL CANCEL MECHANISM
IF ANY THE FOLLOWING OPERATIONS OCCURS DURING CRUISE CONTROL OPERATION, THE MAGNETIC CLUTCH OF THE
ACTUATOR TURNS OFF AND THE MOTOR ROTATES TO CLOSE THE THROTTLE VALVE AND THE CRUISE CONTROL IS RELEASED.
∗ DEPRESSING THE CLUTCH PEDAL (CRUISE CONTROL CLUTCH SWITCH ON). “THE SIGNAL IS INPUT TO TERMINAL 2 OF THE ECU”
(M/T) SHIFT LEVER AT “N” RANGE (NEUTRAL START SWITCH ON). “SIGNAL INPUT TO TERMINAL 2 OF THE ECU” (A/T)
∗ DEPRESSING THE BRAKE PEDAL (STOP LIGHT SWITCH ON). “SIGNAL INPUT TO TERMINAL 1 OF ECU”
∗ PULLED UP THE PARKING BRAKE LEVER (PARKING BRAKE SWITCH ON). “SIGNAL INPUT TO TERMINAL 3 OF THE ECU”
∗ PUSH THE CANCEL SWITCH (CANCEL SWITCH ON). “SIGNAL INPUT TO TERMINAL 18.
162
7. AUTO CANCEL FUNCTION
A) IF ANY OF THE FOLLOWING OPERATE CONDITIONS OCCURS DURING CRUISE CONTROL OPERATION, THE SET SPEED IS
ERASED, CURRENT FLOW TO THE MAGNETIC CLUTCH IS STOPPED AND THE CRUISE CONTROL IS RELEASED. (MAIN SWITCH
TURNS OFF).
WHEN THIS OCCURS, THE IGNITION SWITCH MUST BE TURNED OFF ONCE BEFORE THE MAIN SWITCH WILL TURN ON.
∗ OVER CURRENT TO TRANSISTOR DRIVING MOTOR AND/OR MAGNETIC CLUTCH.
∗ WHEN THE CURRENT CONTINUES TO FLOW TO THE MOTOR IN SIDE THE ACTUATOR, IN THE THROTTLE VALVE “OPEN”
DIRECTION
∗ OPEN CIRCUIT IN MAGNETIC CLUTCH.
∗ MOMENTARY INTERRUPTION OF VEHICLE SPEED SIGNAL.
∗ THE RESUME SWITCH IS ALREADY ON WHEN THE MAIN SWITCH IS TURNED ON.
∗ SHORT CIRCUIT IN CRUISE CONTROL SWITCH.
∗ 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 IS RELEASED. (THE POWER OF MAGNETIC CLUTCH IS CUT OFF UNTIL THE SET SWITCH IS “ON” AGAIN.)
∗ WHEN THE VEHICLE SPEED FAIIS BELOW THE MINIMUM LIMIT, APPROX. 40KM/H (25MPH)
∗ WHEN THE VEHICLE SPEED FALLS MORE THAN 16KM/H (10MPH) 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 OCCURS DURING CRUISE CONTROL OPERATION, THE CRUISE CONTROL IS
RELEASED.
∗ OPEN CIRCUIT FOR TERMINAL 16 OF CRUISE CONTROL ECU.

SYSTEM OUTLINE
1. COOLING FAN OPERATION
WHEN THE IGNITION SW IS TURNED ON, THE CURRENT FROM AM2 FUSE FLOWS TO TERMINAL 1 OF FAN MAIN RELAY →
TERMINAL 3 → GROUND, CAUSING THE FAN MAIN RELAY OF EACH FAN TO TURN ON.
AT THAT TIME, THE CURRENT FROM AM2 FUSE FLOWS TO FAN RELAY NO. 1 AND NO. 2, AND FLOWS FROM TERMINAL 2 OF FAN
RELAY NO. 1 AND NO. 2 → TERMINAL 1 → TERMINAL 2 OF A/C HIGH SINGLE PRESSURE SW → TERMINAL 1 → TERMINAL 8 OF A/C
AMPLIFIER. AT THE SAME TIME, THE CURRENT FROM GAUGE FUSE FLOWS TO TERMINAL 7 OF A/C AMPLIFIER → TERMINAL 1 →
TERMINAL 1 OF FAN RELAY NO. 3 → TERMINAL 2 → GROUND, CAUSING THE FAN RELAY NO. 3 TO TURN ON.
* OPERATION AT LOW SPEED
WHEN THE IGNITION SW IS TURNED ON, THE FAN MAIN RELAY AND FAN RELAY NO. 1, NO. 2 AND NO. 3 TURN ON, THE CURRENT
FLOWS FROM ALT FUSE FLOWS TO TERMINAL 5 OF FAN MAIN RELAY → TERMINAL 4 → CDS FAN FUSE → TERMINAL 2 OF A/C
CONDENSER FAN MOTOR → TERMINAL 1 → TERMINAL 3 OF FAN RELAY NO. 2 → TERMINAL 5 → TERMINAL 5 OF FAN RELAY NO. 3
→ TERMINAL 3 → TERMINAL 2 OF RADIATOR FAN MOTOR → TERMINAL 1 → GROUND, FLOWING TO EACH FAN MOTOR IN SERIES,
CAUSING THE FAN TO ROTATE AT LOW SPEED.
* OPERATION AT HIGH SPEED
DURING A/C OPERATION, WHEN THE PRESSURE OF A/C COMPRESSOR BECOMES HIGHER THAN NORMAL PRESSURE (MORE
THAN 1402 KPA 14.3 KG/CM2 203 PSI), THE A/C SINGLE PRESSURE SW TURNS OFF.
AS A RESULT, FAN RELAY NO. 1 AND NO. 2 TURNS OFF AND THE CURRENT FLOWS FROM ALT FUSE TO TERMINAL 5 OF FAN MAIN
RELAY → TERMINAL 4 → CDS FAN FUSE → TERMINAL 2 OF A/C CONDENSER FAN MOTOR → TERMINAL 1 → TERMINAL 3 OF FAN
RELAY NO. 2 → TERMINAL 4 → GROUND, AT THE SAME TIME FROM TERMINAL 4 OF FAN MAIN RELAY TO RDI FAN FUSE →
TERMINAL 4 OF FAN RELAY NO. 1 → TERMINAL 3 → TERMINAL 2 OF RADIATOR FAN MOTOR → TERMINAL 1 → GROUND, FLOWING
TO EACH FAN MOTOR IN PARALLEL CAUSING THE FAN TO ROTATE AT HIGH SPEED.
NOTE THAT, EVEN IF THE ENGINE COOLANT TEMPERATURE RISES ABOVE 90°C (194°F), THE WATER TEMP. SW (FOR RADIATOR
FAN) TURNS OFF A SIGNAL IS SENT TO TERMINAL 9 OF A/C AMPLIFIER. BECAUSE CURRENT FLOW FROM TERMINAL 8 OF A/C
AMPLIFIER TO TERMINAL 6 IS SHUT OFF, THE CIRCUIT BETWEEN THE A/C SINGLE PRESSURE SW AND GROUND IS DEACTIVATED,
SO THE SAME OPERATION CONTINUES.
2. HEATER BLOWER MOTOR OPERATION
CURRENT IS APPLIED AT ALL TIMES THROUGH THE HTR FUSE TO TERMINAL 5 OF HEATER RELAY.
WHEN THE IGNITION SW IS TURNED TO ON, CURRENT FLOWS THROUGH GAUGE FUSE TO TERMINAL 1 OF HEATER RELAY →
TERMINAL 3 → TERMINAL 10 OF AIR VENT MODE CONTROL SERVO MOTOR → TERMINAL 11 → TERMINAL (A) 4 AND (A) 5 OF A/C
CONTROL ASSEMBLY.
* LOW SPEED OPERATION
WHEN THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO LOW POSITION, THE CURRENT FLOWS TO TERMINAL (A) 4 AND
(A) 5 OF A/C CONTROL ASSEMBLY → TERMINAL (A) 6 OF A/C CONTROL ASSEMBLY → GROUND AND TURNES THE HEATER RELAY
ON.
THIS CAUSES THE CURRENT FLOWING FROM THE HTR FUSE TO TERMINAL 5 OF THE HEATER RELAY TO FLOW TO TERMINAL 4 OF
HEATER RELAY → TERMINAL 1 OF BLOWER MOTOR → TERMINAL 2 → TERMINAL 1 OF BLOWER RESISTOR → TERMINAL 4 →
GROUND, CAUSING THE BLOWER MOTOR TO ROTATE AT LOW SPEED.
* HIGH SPEED OPERATION
WHEN THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO HI POSITION, THE CURRENT FLOWS TO TERMINAL (A) 4 AND (A)
5 OF A/C CONTROL ASSEMBLY → TERMINAL (A) 6 OF A/C CONTROL ASSEMBLY → GROUND AND TURNS THE HEATER RELAY ON.
HEATER RELAY → TERMINAL 1 OF BLOWER MOTOR → TERMINAL 2 → TERMINAL (A) 3 OF A/C CONTROL ASSEMBLY → TERMINAL
(A) 6 → GROUND, CAUSING THE BLOWER MOTOR TO ROTATE AT HIGH SPEED.
* MIDIUM SPEED OPERATION (OPERATION AT M1, M2)
WHEN THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO M1 POSITION, THE CURRENT FLOWS TO TERMINAL (A) 4 AND (A)
5 OF A/C CONTROL ASSEMBLY → TERMINAL (A) 6 OF A/C CONTROL ASSEMBLY → GROUND AND TURNS THE HEATER RELAY ON.
HEATER RELAY → TERMINAL 1 OF BLOWER MOTOR → TERMINAL 2 → TERMINAL 1 OF BLOWER RESISTOR → TERMINAL 2 →
TERMINAL (A) 1 OF A/C CONTROL ASSEMBLY → TERMINAL (A) 6 → GROUND, CAUSING THE BLOWER MOTOR TO ROTATE AT
MEDIUM LOW SPEED.
WHEN THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO M2 POSITION, CURRENT FLOWS FROM TERMINAL 5 OF HEATER
RELAY → TERMINAL 1 OF BLOWER RESISTOR → TERMINAL 3 → TERMINAL (A) 2 OF BLOWER SW (A/C CONTROL ASSEMBLY) →
TERMINAL (A) 6 → GROUND.
THIS CURRENT FLOW FROM BLOWER MOTOR TO GROUND IS GREATER THAN AT M1 POSITION, SO THE BLOWER MOTOR ROTATES
AT MEDIUM HIGH SPEED.
182
3. OPERATION OF AIR INLET SERVO MOTOR
∗ SWITCHING FROM FRESH TO RECIRC
WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS FROM GAUGE FUSE TO TERMINAL 1 OF AIR INLET SERVO MOTOR.
WHEN THE RECIRC/FRESH SW IS SWITCHED TO THE RECIRC SIDE, THE CURRENT FLOWS FROM TERMINAL 4 OF AIR INLET SERVO
MOTOR → TERMINAL 3 → TERMINAL (C) 1 OF A/C CONTROL ASSEMBLY → TERMINAL (C) 15 → GROUND, THE MOTOR ROTATES
AND THE DAMPER MOVES TO THE RECIRC SIDE.
WHEN IT IS IN THE RECIRC POSITION, THE CURRENT IS CUT INSIDE THE SERVO MOTOR AND THE DAMPER STOPS AT THAT
POSITION.
∗ SWITCHING FROM RECIRC TO FRESH
WITH IGNITION SW ON, WHEN THE RECIRC/FRESH SW IS SWITCHED TO THE FRESH SIDE, THE CURRENT FLOWS FROM TERMINAL
4 OF AIR INLET SERVO MOTOR → TERMINAL 1 → TERMINAL (C) 9 OF A/C CONTROL ASSEMBLY → TERMINAL (C) 15 → GROUND,
THE MOTOR ROTATES AND THE DAMPER MOVES TO THE FRESH SIDE.
WHEN IT IS IN THE FRESH POSITION, THE CURRENT IS CUT INSIDE THE SERVO MOTOR AND THE DAMPER STOPS AT THAT
POSITION.
4. OPERATION OF AIR VENT MODE CONTROL SERVO MOTOR
WITH IGNITION SW TURNED ON, THE CURRENT FLOWS FROM GAUGE FUSE TO TERMINAL 6 OF AIR VENT MODE CONTROL SERVO
MOTOR → TERMINAL 7 → GROUND, AND THE DAMPER MOVES TO THE POSITION OF THE MODE SELECTION SW OF THE CONTROL
ASSEMBLY SW.
WHEN THE MODE SELECTION SW OF A/C CONTROL ASSEMBLY IS MOVED TO DEF POSITION WITH THE DAMPER IN THE FACE
POSITION, THE CURRENT FLOWS FROM TERMINAL 5 OF AIR VENT MODE CONTROL SERVO MOTOR TO TERMINAL (C) 14 OF A/C
CONTROL ASSEMBLY → TERMINAL (C) 15 → GROUND.
AS A RESULT, THE SERVO MOTOR OPERATES UNIT THE DAMPER REACHES DEF POSITION.
FOOT/DEF POSITION: THE CURRENT FLOWS FROM TERMINAL 4 OF SERVO MOTOR TO TERMINAL (C) 5 OF A/C CONTROL
ASSEMBLY.
FOOT POSITION: THE CURRENT FLOWS FROM TERMINAL 3 OF SERVO MOTOR TO TERMINAL (C) 4 OF A/C CONTROL ASSEMBLY.
BI–LEVEL POSITION: THE CURRENT FLOWS FROM TERMINAL 2 OF SERVO MOTOR TO TERMINAL (C) 13 OF CONTROL ASSEMBLY.
5. AIR CONDITIONER OPERATION
THE A/C AMPLIFIER RECEIVES VARIOUS SIGNALS, THE ENGINE SPEED SIGNAL FROM THE IGNITER, OUTLET TEMPERATURE
SIGNAL FROM THE A/C THERMISTOR AND CURRENT TEMPARATURE FROM THE WATER TEMP. SW, ETC.
WHEN THE ENGINE IS STARTED AND THE A/C SW (A/C CONTROL ASSEMBLY) IS TURNED ON, THE CURRENT FLOWS FROM A/C
FUSE TO TERMINAL (B) 5 OF A/C CONTROL ASSEMBLY → TERMINAL (B) 6 → TERMINAL 11 OF A/C AMPLIFIER.
AT THIS TIME, THE A/C AMPLIFIER IS ACTIVATED AND CURRENT APPLIED FROM A/C FUSE TO TERMINAL 1 OF A/C MAGNETIC
CLUTCH RELAY FLOWS FROM TERMINAL 3 OF A/C MAGNETIC CLUTCH RELAY → TERMINAL 15 OF A/C AMPLIFIER → TERMINAL 6 →
GROUND. THIS CAUSES THE A/C MAGNETIC CLUTCH RELAY TO TURN ON, SO CURRENT APPLIED TO TERMINAL 2 OF A/C
MAGNETIC CLUTCH RELAY FLOWS FROM TERMINAL 4 OF A/C MAGNETIC CLUTCH RELAY → TERMINAL 1 OF A/C MAGNETIC
CLUTCH → GROUND, CAUSING THE A/C COMPRESSOR TO OPERATE.
WITH THE ACTIVATION OF A/C AMPLIFIER, CURRENT APPLIED FROM A/C FUSE TO TERMINAL 2 OF VSV (FOR A/C IDLE–UP) FLOWS
FROM TERMINAL 1 OF VSV (FOR A/C IDLE–UP) → TERMINAL 14 OF A/C AMPLIFIER → TERMINAL 6 → GROUND, AND TURNS ON THE
VSV TO AVOID LOWERING THE ENGINE SPEED DURING AIR CONDITIONER OPERATION.
WHEN ANY OF THE FOLLOWING SIGNALS ARE INPUT TO THE A/C AMPLIFIER, THE AMPLIFIER OPERATES TO TURN OFF THE AIR
CONDITIONER.
∗ THE ENGINE SPEED DECREASES. (3S–GTE)
∗ COOLANT TEMP. SIGNAL IS HIGH.
∗ A SIGNAL THAT THE TEMPERATURE AT THE AIR OUTLET IS LOW.
∗ A SIGNAL THAT THE REFRIGERANT PRESSURE IS ABNORMALLY HIGH OR LOW.
