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.

HOW TO USE THIS MANUAL
The “Current Flow Chart” section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system are
explained. Since all System Circuit diagrams start from the power source, the power source system must be fully understood.
POWER SOURCE (Current Flow Chart)
The chart below shows the route by which current flows from the battery to each electrical source (Fusible Link, Circuit
Breaker, Fuse, etc.) and other parts.
The next page and following pages shown the parts to which each electrical source outputs current.
POWER SOURCE

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

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 a 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
SYSTEM OUTLINE
THE ENGINE CONTROL SYSTEM UTILIZES A MICROCOMPUTER AND MAINTAINS OVERALL CONTROL OF THE ENGINE AN OUTLINE
OF ENGINE CONTROL IS GIVEN HERE.
1. INPUT SIGNALS
(1) WATER TEMP. SIGNAL SYSTEM
THE WATER TEMP. SENSOR DETECTS THE ENGINE COOLANT TEMP. AND HAS A BUILT–IN THERMISTOR WITH A RESISTANCE
WHICH VARIES ACCORDING TO THE WATER TEMP. THUS THE WATER TEMP. IS INPUT IN THE FORM OF A CONTROL SIGNAL TO
TERMINAL THW OF THE ECU.
(2) INTAKE AIR TEMP. SIGNAL SYSTEM
THE INTAKE AIR TEMP. SENSOR IS INSTALLED INSIDE THE AIR FLOW METER AND DETECTS THE INTAKE AIR TEMP. WHICH IS
INPUT AS A CONTROL SIGNAL TO TERMINAL THA OF THE ECU.
(3) OXYGEN SENSOR SIGNAL SYSTEM
THE OXYGEN DENSITY IN THE EXHAUST EMISSIONS IS DETECTED AND INPUT AS A CONTROL SIGNAL TO TERMINAL OX1 OF
THE ECU. TO MAINTAIN STABLE DETECTION PERFORMANCE BY THE OXYGEN SENSOR, A HEATER IS USED FOR WARMING
THE SENSOR. THE HEATER IS ALSO CONTROLLED BY THE ECU (HT).
(4) RPM SIGNAL SYSTEM
CRANKSHAFT POSITION IS DETECTED BY THE PICK–UP COIL INSTALLED INSIDE THE DISTRIBUTOR. CRANKSHAFT POSITION
IS INPUT AS A CONTROL SIGNAL TO TERMINALS G1 AND G2 OF THE ECU, AND RPM IS INPUT TO TERMINAL NE.
(5) THROTTLE SIGNAL SYSTEM
THE THROTTLE POSITION SENSOR DETECTS THE THROTTLE VALVE OPENING ANGLE WHICH IS INPUT AS A CONTROL SIGNAL
TO TERMINAL VTA OF THE ECU, OR WHEN THE VALVE IS FULLY CLOSED, TO TERMINAL IDL.
(6) VEHICLE SPEED SIGNAL SYSTEM
THE SPEED SENSOR, INSTALLED INSIDE THE COMBINATION METER, DETECTS THE VEHICLE SPEED AND INPUTS A CONTROL
SIGNAL TO TERMINAL SPD OF THE ECU.
(7) A/C SW SIGNAL SYSTEM
THE OPERATING VOLTAGE OF THE A/C MAGNET CLUTCH IS DETECTED AND INPUT IN THE FORM OF A CONTROL SIGNAL TO
TERMINAL A/C 1 OF THE ECU.
(8) BATTERY SIGNAL SYSTEM
VOLTAGE IS CONSTANTLY APPLIED TO TERMINAL BATT OF THE ECU. WHEN THE IGNITION SW IS TURNED TO ON, VOLTAGE
FOR ECU OPERATION IS APPLIED VIA THE EFI MAIN RELAY TO TERMINALS +B AND B1 OF THE ECU.
(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 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 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 ECU.
(12) ENGINE KNOCK CONTROL SYSTEM
ENGINE KNOCKING IS DETECTED BY THE KNOCK SENSOR AND INPUT AS A CONTROL SIGNAL TO TERMINAL KNK OF THE
ECU.
(13) ELECTRICAL IDLE–UP 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
* EFI (ELECTRONIC FUEL INJECTION) SYSTEM
THE EFI SYSTEM MONITORS THE ENGINE REVOLUTIONS THROUGH THE SIGNALS EACH SENSOR (INPUT SIGNALS (1) TO (12))
INPUTS TO THE ECU. BASED ON THIS DATA AND THE PROGRAM MEMORIZED IN THE ECU. THE MOST APPROPRIATE FUEL
INJECTION TIMING IS DECIDED AND CURRENT IS OUTPUT TO TERMINALS #1, #2, #3 AND #4 OF THE ECU. CAUSING THE
INJECTORS TO OPERATE (TO INJECT FUEL). IT IS THIS SYSTEM WHICH, THROUGH THE WORK OF THE ECU. FINELY CONTROLS
FUEL INJECTION IN RESPONSE TO DRIVING CONDITIONS.
* ESA (ELECTRONIC SPARK ADVANCE) SYSTEM
THE ESA SYSTEM MONITORS THE ENGINE REVOLUTIONS USING THE SIGNALS (INPUT SIGNALS (1, 3, 4, 6, 7, 9, 11)) INPUT TO THE
ECU FROM EACH SENSOR. BASED ON THIS DATA AND THE PROGRAM MEMORIZED IN THE ECU. THE MOST APPROPRIATE
IGNITION TIMING IS DECIDED AND CURRENT IS OUTPUT TO TERMINAL IGT OF THE ECU. THIS OUTPUT CONTROLS THE IGNITER
TO PRODUCE THE MOST APPROPRIATE IGNITION TIMING FOR THE DRIVING CONDITIONS.
* FUEL PUMP CONTROL SYSTEM
COMPUTER OPERATION OUTPUTS TO TERMINAL FPR AND CONTROLS THE FUEL PUMP CONTROL RELAY AND THUS CONTROLS
THE FUEL PUMP DRIVE SPEED IN RESPONSE TO CONDITIONS.
54
* OXYGEN SENSOR HEATER CONTROL SYSTEM
THE OXYGEN SENSOR HEATER CONTROL SYSTEM TURNS THE HEATER TO ON WHEN THE INTAKE AIR VOLUME IS LOW (TEMP.
OF EXHAUST EMISSIONS LOW). AND WARMS UP THE OXYGEN SENSOR TO IMPROVE DETECTION PERFORMANCE OF THE
SENSOR. THE ECU EVALUATES THE SIGNALS FROM EACH SENSOR (INPUT SIGNALS (1, 6, 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 THE RPM AND PROVIDES IDLING STABILITY FOR FAST IDLE–UP WHEN
THE ENGINE IS COLD AND WHEN THE IDLE SPEED HAS DROPPED DUE TO ELECTRICAL LOAD, ETC. THE ECU EVALUATES THE
SIGNALS FROM EACH SENSOR (INPUT SIGNALS (1, 4 TO 8, 11, 13)), OUTPUTS CURRENT TO TERMINALS RSC AND RSO AND
CONTROLS THE ISC VALVE.
* EGR CONTROL SYSTEM
WITH THE EGR CONTROL SYSTEM, THE ECU EVALUATES THE (INPUT SIGNALS (1, 4, 10)), FROM EACH SENSOR, CURRENT IS
OUTPUT TO TERMINAL EGR AND OPERATION OF THE EGR VALVE 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 ECU EVALUATES THE SIGNALS FROM EACH SENSOR (INPUT SIGNALS (1, 4, 5)), OUTPUTS CURRENT TO
TERMINAL T–VIS 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 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 ECU MEMORY OR ELSE STOPS THE ENGINE.

SYSTEM OUTLINE
CURRENT FROM THE BATTERY FLOWS CONTINUOUSLY FROM FL 2.0L → FL ALT → TAILLIGHT RELAY (COIL SIDE) → TERMINAL (A) 2
OF RETRACT CONTROL RELAY, FL 2.0L → HEADLIGHT RELAY (COIL SIDE) → TERMINAL (B) 8 OF RETRACT CONTROL RELAY.
WHEN THE IGNITION SW IS TURNED ON, THE CURRENT FLOWING THROUGH THE ECU–IG FUSE FLOWS TO TERMINAL (A) 4 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 (A) 9 OF THE RETRACT CONTROL RELAY, CAUSING THE RETRACT CONTROL RELAY TO OPERATE SO THAT THE
TAILLIGHT RELAY AND FOG LIGHT RELAY TURN ON. THIS CAUSES CURRENT TO FLOW FROM THE TAILLIGHT RELAY (POINT SIDE)
→ TAIL FUSE → EACH TAILLIGHT, AND FOG LIGHT RELAY (POINT SIDE) → FOG LIGHTS.
ACCORDINGLY, EVEN WHEN THE LIGHT CONTROL SW IS IN OFF POSITION, EACH OF THE LIGHTS JUST MENTIONED LIGHTS UP.
THIS SYSTEM CONTINUES TO OPERATE UNTIL THE IGNITION SW IS TURNED OFF.

SYSTEM OUTLINE
CURRENT ALWAYS FLOWS TERMINAL 4 OF THE POWER MAIN RELAY THROUGH THE POWER FUSE. WITH THE IGNITION SW
TURNED ON, CURRENT FLOWS THROUGH THE GAUGE FUSE TO TERMINAL 2 OF THE POWER MAIN RELAY → TERMINAL 3 → TO
GROUND. THIS ACTIVATES THE RELAY AND CURRENT FLOWING TO TERMINAL 1 OF THE POWER MAIN RELAY → TO TERMINAL 6
OF THE POWER WINDOW MASTER SW AND TERMINAL 5 OF THE POWER WINDOW SW RH (PASSENGER’S).
1. MANUAL UP OPERATION (DRIVER’S WINDOW)
WITH THE IGNITION SW TURNED ON AND WITH THE POWER WINDOW MASTER SW IN UP POSITION, THE CURRENT FLOWING TO
TERMINAL 6 OF THE POWER WINDOW MASTER SW FLOWS TO TERMINAL 5 OF THE MASTER SW → TERMINAL 2 OF THE POWER
WINDOW MOTOR LH (DRIVER’S) → MOTOR → TERMINAL 1 → TERMINAL 1 OF THE MASTER SW → TERMINAL 3 → TO GROUND AND
CAUSES THE POWER WINDOW MOTOR TO ROTATE IN THE UP DIRECTION. THE WINDOW ASCENDS ONLY WHILE THE SW IS BEING
PUSHED. IN DOWN OPERATION, THE FLOW OF CURRENT FROM TERMINAL 6 OF THE POWER WINDOW MASTER SW TO TERMINAL
1 OF THE MASTER SW CAUSES THE FLOW OF CURRENT FROM TERMINAL 1 OF THE MOTOR → MOTOR → TERMINAL 2 →
TERMINAL 5 OF THE MASTER SW → TERMINAL 3 → TO GROUND, FLOWING IN THE OPPOSITE DIRECTION TO MANUAL UP
OPERATION AND CAUSING THE MOTOR TO ROTATE IN REVERSE, LOWERING THE WINDOW.
2. AUTO DOWN OPERATION
WITH THE IGNITION SW ON AND WITH THE DRIVER’S SW OF THE POWER WINDOW MASTER SW IN DOWN POSITION, CURRENT
FLOWING TO TERMINAL 6 OF THE MASTER SW FLOWS TO TERMINAL 1 OF THE MASTER SW → TERMINAL 1 OF THE POWER
WINDOW MOTOR → MOTOR → TERMINAL 2 → TERMINAL 5 OF THE MASTER SW → TERMINAL 3 → TO 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 5 OF THE MASTER SW AND
TERMINAL 3 INCREASES. AS A RESULT, THE SOLENOID STOPS OPERATING, THE DRIVER’S SW TURNS OFF AND FLOW FROM
TERMINAL 6 OF THE MASTER SW TO TERMINAL 1 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 PUSHED TO THE UP SIDE DURING AUTO DOWN OPERATION, A GROUND CIRCUIT OPENS IN THE
MASTER SW AND CURRENT DOES NOT FLOW FROM TERMINAL 5 OF THE MASTER SW → TO TERMINAL 3, SO THE MOTOR STOPS,
CAUSING AUTO DOWN OPERATION TO STOP. IF THE DRIVER’S SW IS PUSHED CONTINUOUSLY, THE MOTOR ROTATES IN THE UP
DIRECTION IN MANUAL UP OPERATION.
4. MANUAL OPERATION BY POWER WINDOW SW (PASSENGER’S WINDOW)
WITH POWER WINDOW SW (PASSENGER’S) PUSHED TO THE UP SIDE, CURRENT FLOWING FROM TERMINAL 6 OF THE POWER
WINDOW SW FLOWS TO TERMINAL 5 OF THE POWER WINDOW SW → TERMINAL 2 OF THE WINDOW MOTOR → MOTOR →
TERMINAL 1 → TERMINAL 1 OF THE POWER WINDOW SW → TERMINAL 3 → TERMINAL 4 OF THE MASTER SW → TERMINAL 3 → TO
GROUND AND CAUSES THE POWER WINDOW MOTOR (PASSENGER’S) TO ROTATE IN THE UP DIRECTION. UP OPERATION
CONTINUES ONLY WHILE THE POWER WINDOW SW IS PUSHED TO THE UP SIDE. WHEN THE WINDOW DESCENDS, THE CURRENT
FLOWING TO THE MOTOR FLOWS IN THE OPPOSITE DIRECTION, FLOM TERMINAL 1 → MOTOR → TO TERMINAL 2, AND THE MOTOR
ROTATES IN REVERSE. WHEN THE WINDOW LOCK SW IS PUSHED TO THE LOCK SIDE, THE GROUND CIRCUIT TO THE
PASSENGER’S WINDOW BECOMES OPEN.
AS A RESULT, EVEN IF OPEN/CLOSE OPERATION OF THE PASSENGER’S WINDOW IS TRIED, THE CURRENT FROM TERMINAL 6 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 CONTROL RELAY OPERATES AND CURRENT FLOWS FROM POWER
FUSE → TERMINAL 8 OF THE DOOR LOCK ECU → TERMINAL 15 → TERMINAL 2 OF THE POWER MAIN RELAY → TERMINAL 3 → TO
GROUND FOR ABOUT 60 SECONDS. THE SAME AS NORMAL OPERATION, THE CURRENT FLOWS FROM POWER FUSE → TERMINAL
4 OF THE POWER MAIN RELAY → TERMINAL 1 → TERMINAL 6 OF THE POWER WINDOW MASTER SW AND TERMINAL 1 OF THE
POWER MAIN RELAY → TO TERMINAL 6 OF POWER WINDOW SW RH (PASSENGER’S). AS A RESULT, FOR ABOUT 60 SECONDS
AFTER THE IGNITION SW IS TURNED OFF. IT IS POSSIBLE TO RAISE AND LOWER THE POWER WINDOW BY THE FUNCTIONING OF

SYSTEM OUTLINE
CURRENT ALWAYS FLOWS TO TERMINAL 8 OF THE DOOR LOCK ECU AND TERMINAL 4 OF THE POWER MAIN RELAY THROUGH
POWER FUSE.
1. MANUAL LOCK OPERATION
TO CHANGE DOOR LOCK SW AND KEY SW TO LOCK POSITION, A LOCK SIGNAL IS INPUT TO TERMINAL 10, 12 OF THE DOOR LOCK
ECU AND CAUSES THE RELAY TO FUNCTION. CURRENT FLOWS FROM TERMINAL 8 OF THE ECU → TERMINAL 4 → TERMINAL 7 OF
THE DOOR LOCK MOTOR → TERMINAL 5 → TERMINAL 3 OF THE ECU → TERMINAL 16 → TO GROUND AND DOOR LOCK SOLENOID
CAUSES THE DOOR TO LOCK.
2. MANUAL UNLOCK OPERATION
TO CAHNGE DOOR LOCK CONTROL SW AND KEY SW RH TO UNLOCK POSITION, AN UNLOCK SIGNAL IS INPUT TO TERMINAL 11 OF
THE DOOR LOCK ECU AND CAUSES THE RELAY TO FUNCTION. CURRENT FLOWS FROM TERMINAL 8 OF THE ECU → TERMINAL 3
→ TERMINAL 5 OF THE DOOR LOCK MOTOR → TERMINAL 7 → TERMINAL 4 OF THE ECU → TERMINAL 16 → TO GROUND AND
DOOR LOCK SOLENOID CAUSES DOOR TO UNLOCK.
3. DOUBLE OPERATION UNLOCK OPERATION
WHEN THE DOOR LOCK KEY SW (DRIVER’S) IS TURNED TO THE UNLOCK SIDE, ONLY THE DRIVER’S DOOR IS MECHANICALLY
UNLOCKED. TURNING THE DOOR LOCK KEY SW (DRIVER’S) TO THE UNLOCK SIDE CAUSES A SIGNAL TO BE INPUT TO TERMINAL 9
OF THE ECU, AND IF THE SIGNAL IS INPUT AGAIN WITHIN 3 SECONDS BY TURNING THE SWITCH TO THE UNLOCK SIDE AGAIN,
CURRENT FLOWS TERMINAL 3 → TERMINAL 5 OF DOOR LOCK MOTOR → TERMINAL 7 → TERMINAL 4 OF THE ECU → TERMINAL 16
→ GROUND, CAUSING THE DOOR LOCK MOTOR TO OPERATE AND UNLOCK THE PASSENGER’S DOOR.
4. IGNITION KEY REMINDER OPERATION
* OPERATING DOOR LOCK KNOB (IN DOOR LOCK SOLENOIDS OPERATION)
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 ECU. AS
A RESULT, THE CURRENT FLOWS FROM TERMINAL 8 OF THE ECU → TERMINAL 3 → TERMINAL 5 OF THE DOOR LOCK MOTOR →
TERMINAL 7 → 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
SOLENOIDS, 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 ECU FLOWS FROM TERMINAL 8 OF THE ECU → TERMINAL 3 → TERMINAL 5 OF THE DOOR
LOCK MOTOR → TERMINAL 7 → TERMINAL 4 OF THE ECU → TERMINAL 16 → TO GROUND AND CAUSES ALL THE DOOR TO
UNLOCK.
* IN CASE OF KEY LESS LOCK
WITH IGNITION KEY IN CYLINDER (UNLOCK WARNING SW ON), WHEN THE UNLOCK FUNCTION IS DISTURBED MORE THAN 0.2
SECONDS, FOR EXAMPLE PUSHING THE DOOR LOCK KNOB ETC., THE DOOR HOLDS ON LOCK CONDITION. CLOSING THE DOOR
AFTER, DOOR COURTESY SW INPUTS THE SIGNAL INTO TERMINAL 2 OR 14 OF THE ECU. BY THIS INPUT SIGNAL, THE RELAY
WORKS AND CURRENT FLOWS FROM TERMINAL 8 OF THE ECU → TERMINAL 3 → TERMINAL 5 OF THE DOOR LOCK MOTOR →
TERMINAL 7 → TERMINAL 4 OF THE ECU → TERMINAL 16 → TO GROUND AND CAUSES ALL THE DOORS TO UNLOCK.

SYSTEM OUTLINE
WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS TO TERMINAL 2 OF THE REAR WASHER MOTOR, TERMINAL 1 OF THE
REAR WIPER MOTOR AND RELAY THROUGH THE WIPER FUSE.
1. REAR WIPER NORMAL OPERATION
WITH THE IGNITION SW TURNED ON AND REAR WIPER AND WASHER SW TURNED ON, THE CURRENT FLOWING TO ERMINAL 1 OF
THE REAR WIPER RELAY FLOWS TO TERMINAL 3 OF THE RELAY → TERMINAL 1 OF THE REAR WIPER AND WASHER SW →
TERMINLA 16 → TO GROUND. THUS, THE RELAY COIL IS ACTIVATED AND THE CURRENT TO TERMINAL 1 OF THE REALY FLOWS TO
TERMINAL LB → TERMINAL LB OF THE REAR WIPER MOTOR → MOTOR → TO GROUND AND CAUSES THE MOTOR TO OPERATE
THE WIPER.
2. REAR WIPER INTERMITTENT OPERATION
WHEN THE IGNITION SW IS ON AND THE REAR WIPER AND WASHER SW IS TURNED TO INT POSITION, CURRENT FLOWING TO
TERMINAL 1 OF 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 CHARGING AND DISCHARGING OF THE CONDENSER
INSTALLED INSIDE THE RELAY.
3. WASHER OPERATION
WITH THE IGNITION SW TURNED ON AND THE REAR WIPER AND WASHER SW TURNED TO ON POSITION, WHEN THE WIPER SW IS
TURNED FURTHER, THE CURRENT FLOWING TO TERMINAL 2 OF THE REAR WASHER MOTOR FLOWS TO TERMINAL 3 OF THE
MOTOR → TERMINAL 2 OF THE REAR WIPER AND WASHER SW → TERMINAL 16 → TO GROUND SO THAT THE WASHER MOTOR
ROTATES AND THE WINDOW WASHER EJECTS 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.

SYSTEM OUTLINE
CURRENT ALWAYS FLOWS TO TERMINAL 4 OF THE POWER MAIN RELAY THROUGH THE POWER FUSE, WITH THE IGNITION SW TURNED ON,
CURRENT FLOWS THROUGH THE GAUGE FUSE TO TERMINAL 2 OF THE POWER MAIN RELAY. THIS ACTIVATES THE RELAY AND CURRENT FLOWING
TO TERMINAL 4 OF THE POWER MAIN RELAY FLOWS TO TERMINAL 1 OF THE POWER MAIN RELAY → TO TERMINAL 6 OF THE SUN ROOF CONTROL
RELAY.
1. SLIDE OPEN OPERATION
WHEN THE IGNITION SW IS ON AND THE SUN ROOF SW PUSHED TO THE OPEN SIDE, A SIGNAL IS INPUT TO TERMINAL 8 OF THE SUN ROOF
CONTROL RELAY. WHEN THIS OCCURS ACTIVATING THE RELAY SO THAT CURRENT FLOWS FROM TERMINAL 6 OF THE RELAY → TERMINAL 5 →
TERMINAL 1 OF THE SUN ROOF MOTOR → MOTOR → TERMINAL 3 → TERMINAL 1 OF THE RELAY → TERMINAL 12 → GROUND, THE MOTOR
ROTATES TO THE OPEN SIDE AND THE SUN ROOF SLIDES OPEN AS LONG AS THE SUN ROOF CONTROL SW IS PUSHED TO THE OPEN SIDE.
WHEN THE SUN ROOF IS OPENED COMPLETELY, EVEN IF THE SUN ROOF SW IS PUSHED CONTINUOUSLY, THE CURRENT TO THE SUN ROOF MOTOR
INCREASES.
IN THIS CASE, THE CIRCUIT BREAKER BUILT INTO THE MOTOR OPENS AND CUTS OUT THE CURRENT TO THE MOTOR, PREVENTING THE MOTOR
FROM BURNING OUT.
2. SLIDE CLOSE OPERATION
WHEN THE IGNITION SW IS ON AND THE SUN ROOF CONTROL SW IS PUSHED TO THE CLOSE SIDE, A SIGNAL IS INPUT TO TERMINAL 7 OF THE SUN
ROOF CONTROL RELAY. THIS ACTIVATES THE RELAY AND THE CURRENT FLOWING TO TERMINAL 6 FLOWS TO TERMINAL 1 → TERMINAL 3 OF THE
SUN ROOF MOTOR → MOTOR → TERMINAL 1 → TERMINAL 5 OF THE RELAY → TERMINAL 12 → GROUND. THIS CAUSES THE MOTOR TO ROTATE TO
THE CLOSE SIDE AND SLIDE CLOSE OPERATION CONTINUES AS LONG AS THE SUN ROOF CONTROL SW IS PUSHED TO THE CLOSE SIDE.
100 MM BEFORE THE FULLY CLOSED POSITION THE SUN ROOF LIMIT NO. 1 SW TURN OFF. THIS SIGNAL IS INPUT INTO THE RELAY, SO THE RELAY
STOPS OPERATION. THUS CURRENT DOES NOT FLOW TO THE SUN ROOF MOTOR AND THE SUN ROOF AUTOMATICALLY STOPS.
IF THE SUN ROOF SW IS THEN PUSH AGAIN, THE TIMER INSTALLED IN THE SUN ROOF CONTROL TURNS ON AND THE RELAY OPERATES FOR 0.65
SEC. TO RE–OPERATE THE MOTOR SO THAT THE SUN ROOF LIMIT SW NO. 1 TURNS ON (SUN ROOF LIMIT SW NO. 2 TURNS OFF). AS A RESULT, AS
LONG AS THE SUN ROOF SW IS PUSHED, SLIDE CLOSE OPERATION OCCURS AND THE SUN ROOF IS ABLE TO FULLY CLOSE.
3. TILT UP OPERATION
WHEN THE SUN ROOF CONTROL SW IS PUSHED TO TILT UP POSITION, WITH THE IGNITION SW TURNED ON AND THE SLIDE ROOF COMPLETELY
CLOSED A SIGNAL IS INPUT TO TERMINAL 2 OF THE SUN ROOF CONTROL RELAY AND SUN ROOF LIMIIT SW NO. 2 IS TURNED OFF (SUN ROOF LIMIT
SW NO. 1 TURNS ON) SIMULTANEOUSLY,. CAUSING THE SUN ROOF CONTROL RELAY TO OPERATE. AS A RESULT, THE RELAY IS ACTIVATED AND
CURRENT FLOWS FROM TERMINAL 6 OF THE RELAY → TERMINAL 1 → TERMAINAL 3 OF THE SUN ROOF MOTOR → MOTOR → TERMINAL 1 →
TERMINAL 5 OF THE RELAY → TERMINAL 12 → GROUND, ROTATING THE MOTOR FOR TILT UP OPERATION.
4. TILT DOWN OPERATION
WHEN THE SUN ROOF CONTROL SW IS PUSHED TO THE TILT DOWN POSITION, WITH THE IGNITION SW TURNED ON AND THE SLIDE ROOF TILTED
UP, A SIGNAL IS INPUT TO TERMINAL 9 OF THE SUN ROOF CONTROL RELAY SIGNALS THAT SUN ROOF LIMIT SW NO. 1 AND NO. 2 ARE OFF ARE
INPUT SEPARATELY TO TERMINAL 10 AND TERMINAL 4.
AS A RESULT, RELAY ACTIVATES AND THE CURRENT FLOWS FROM TERMINAL 6 OF THE RELAY → TERMINAL 5 → TERMINAL 1 OF THE SUN ROOF
MOTOR → MOTOR → TERMINAL 3 → TERMINAL 1 OF THE RELAY → TERMINAL 12 → GROUND, ROTATING THE MOTOR FOR TILT DOWN OPERATION.

SYSTEM OUTLINE
THIS SYSTEM ALLOWS EASIER ENTRY AND EXIT BY THE DRIVER BY MOVING THE STEERING POSITION TO THE UPPER POSITION
WHEN THE IGNITION KEY IS REMOVED.
CURRENT ALWAYS FLOWS FROM THE POWER FUSE TO TERMINAL 1 OF AUTO TILT AWAY ECU. WHEN THE IGNITION SW IS TURNED
ON, CURRENT FLOWS FROM THE GAUGE FUSE AS FAR AS TERMINAL 6.
1. TILT–UP OPERATION
WHEN IGNITION KEY IS REMOVED FROM THE IGNITION KEY CYLINDER (UNLOCK WARNING SW OFF), A WARNING SW OFF SIGNAL
IS INPUT TO TERMINAL 2 OF THE AUTO TILT AWAY ECU. AS A RESULT, THE AUTO TILT AWAY OPERATES AND CURRENT FLOWS
FROM TERMINAL 4 OF THE AUTO TILT AWAY ECU → TERMINAL 1 OF THE AUTO TILT AWAY ACTUATOR → ACTUATOR → TERMINAL 2
→ TERMINAL 5 OF THE AUTO TILT AWAY ECU, CAUSING THE ACTUATOR TO ROTATE AND RELEASE THE LOCK MECHANISM
LOCKED AT THE MEMORY POSITION (THE POSITION SELECTED USING THE TILT ADJUSTMENT LEVER). THE STEERING WHEEL THE
MOVES FROM THE MEMORY POSITION TO THE UPPER POSITION USING SPRING FORCE, THEN MECHANICAL LOCK OCCURS.
2. TILT RETURN OPERATION
WHEN THE IGNITION KEY IS INSERTED INTO THE IGNITION KEY CYLINDER (UNLOCK WARNING SW ON), A WARNING SW ON SIGNAL
IS INPUT TO TERMINAL 2 OF THE AUTO TILT AWAY ECU. AS A RESULT, THE AUTO TILT AWAY ECU OPERATES AND CURRENT
FLOWS FROM TERMINAL 5 OF THE AUTO TILT AWAY ECU → TERMINAL 2 OF THE AUTO TILT AWAY ACTUATOR → ACTUATOR →
TERMINAL 1 → TERMINAL 4 OF THE AUTO TILT AWAY ECU, CAUSING THE ACTUATOR TO ROTATE AND RELEASE THE LOCK
MECHANISM LOCKED AT THE UPPER POSITION. THE STEERING WHEEL CAN THEN BE RETURNED BY HAND TO THE MEMORY
POSITION, WHERE MECHANICAL LOCK OCCURS.

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 (A) 8 OF CRUISE CONTROL ECU. AS A RESULT, THE CRUISE CONTROL ECU
FUNCTIONS AND THE CURRENT TO TERMINAL (A) 1 OF CRUISE CONTROL ECU TO TERMINAL (A) 9 OF 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) 7 OF CRUISE CONTROL INDICATOR
LIGHT → TERMINAL (B) 2 → TERMINAL (B) 6 OF CRUISE CONTROL ECU → TERMINAL (A) 9 → TO GROUND, CAUSING THE CRUISE
CONTROL INDICATOR LIGHT TO LIGHT UP, INDICATING THAT THE 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. 36 KM/H, 22 MPH TO 200 KM/H, 124 MPH), A SIGNAL IS INPUT TO TERMINAL (B) 8 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 (A) 7 OF THE CRUISE CONTROL ECU FROM THE SPEED SENSOR, 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 (B) 4 → TERMINAL 6 OF CRUISE CONTROL ACTUATOR → TERMINAL 7 → TERMINAL (B) 10
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 (B) 10 OF ECU → TERMINAL 7 OF
CRUISE CONTROL ACTUATOR → TERMINAL 6 → TERMINAL (B) 4 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 THE 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, 25 MPH) AFTER CANCELING THE SET
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 OF THE FOLLOWING OPERATIONS OCCURS DURING CRUISE CONTROL OPERATION, THE SAFETY MAGNET CLUTCH OF THE
ACTIVATOR MOTOR 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). “SIGNAL INPUT TO TERMINAL (A) 4 OF ECU”
∗ DEPRESSING THE BRAKE PEDAL (STOP LIGHT SWITCH ON). “SIGNAL INPUT TO TERMINAL (A) 2 OF ECU”
∗ DEPRESSING THE PARKING BRAKE PEDAL (PARKING BRAKE SWITCH ON). “SIGNAL INPUT TO TERMINAL (A) 5 OF ECU”
∗ PUSH THE CANCEL SWITCH (CANCEL SWITCH ON). “SIGNAL INPUT TO TERMINAL (B) 8”
120
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 SAFETY 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 TRANSISTER DRIVING MOTOR AND/OR SAFETY MAGNETIC CLUTCH.
∗ CURRENT TO CONTROL THE THROTTLE VALVE IN MOTOR BECOMES ALWAYS “ON”.
∗ OPEN CIRCUIT IN SAFETY 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 OCCUR DURING CRUISE CONTROL OPERATION, THE SET SPEED IS ERASED AND THE CRUISE
CONTROL IS RELEASED. (THE POWER OF SAFETY MAGNETIC CLUTCH IS CUT OFF UNTIL THE SET SWITCH IS “ON” AGAIN.)
∗ WHEN THE VEHICLE SPEED FALLS BELOW THE MINIMUM SPEED LIMIT, APPROX. 36 KM/H (22 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 OCCURS DURING CRUISE CONTROL OPERATION, THE CRUISE CONTROL IS RELEASED. BUT IN THIS
CASE, THE SET SPEED IS NOT ERASED. IF THE VEHICLE SPEED IS MORE THAN THE MINIMUM SPEED LIMIT (APPROX. 36 KM/H 22 MPH), CRUISE
CONTROL OPERATION IS POSSIBLE USING “SET” OR “RESUME” ON THE CONTROL SWITCH.
∗ OPEN CIRCUIT FOR TERMINAL (A) 3 OF CRUISE CONTROL ECU AND TERMINAL 3 OF STOP LIGHT SWITCH.

ABS (ANTI–LOCK BRAKE SYSTEM)
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 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.
(4) DECELERATION SENSOR SIGNAL
THE DEGREE OF VEHICLE DECELERATION IS DETECTED AND INPUT TO THE ABS ECU.
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 REDUCTION, HOLDING AND INCREASE ARE
REPLATED TO MAINTAIN VEHICLE STABILITY AND TO IMPROVE STEERBILITY DURING SUDDEN BRAKING.

SRS AIRBAG
NOTICE: When inspecting or repairing the SRS AIRBAG, perform the operation in accordance with the
following precautionary instructions and the procedure and precautions in the Repair Manual for the applicable
model year.
Malfunction symptoms of the airbag system are difficult to confirm, so the diagnostic codes become the most
important source of information when troubleshooting.
When troubleshooting the airbag system, always inspect the diagnostic codes before disconnecting the
battery.
Work must be started after 20 seconds or longer from the time the Ignition SW is set to the “LOCK” position
and the negative (–) terminal cable is disconnected from the battery.
(The airbag system is equipped with a back–up power source so that if work is started within 20 seconds of
disconnecting the negative (–) terminal cable of the battery, the airbag may be deployed.)
When the negative (–) terminal cable is disconnected from the battery, memory of the clock and audio systems
will be cancelled. So before starting work, make a record of the contents memorized by each memory system.
Then when work is finished, reset the clock and audio system as before.
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 airbag inflates for some
reason.)
Store the steering wheel pad where the ambient temperature remains below 93°C (200°F), without high
humidity and away from electrical noise.
Never use airbag parts from another vehicle. When replacing airbag parts, replace them with new parts.
Never disassemble or repair the steering wheel pad, center airbag sensor assembly or front airbag sensors.
Before repairing the body, remove the airbag sensors if during repair shocks are likely to be applied to the
sensors due to vibration of the body or direct tapping with tools or other parts.
Do not reuse a steering wheel pad or front airbag sensors.
After evaluating whether the center airbag sensor assembly is damaged or not, decide whether or not to reuse
it. (See the Repair Manual for the method for evaluating the center airbag sensor assembly.)
When troubleshooting the airbag system, use a high–impedance (Min. 10k/V) tester.
The wire harness of the airbag system is combined with the cowl wiring harness assembly.
The vehicle wiring harness exclusively for the airbag system is distinguished by corrugated yellow tubing, as
are the connectors.
Do not measure the resistance of the airbag squib.
(It is possible this will deploy the airbag and is very dangerous.)
If the wire harness used in the airbag system is damaged, replace the whole wire harness assembly.
When the connector to the airbag front sensors can be repaired alone (when there is no damage to the wire
harness), use the repair wire specially designed for the purpose.
(Refer to the Repair Manual for the applicable Model year for details of the replacement method.)
INFORMATION LABELS (NOTICES) are attached to the periphery of the airbag components. Follow the
instructions on the notices.
129
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.
130
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 6 OF THE CENTER AIRBAG SENSOR ASSEMBLY. WHEN THE IGNITION SW IS
TURNED TO ACC OR ON, CURRENT FROM THE CIG & RAD FUSE FLOW TO TERMINAL 14 OF THE CENTER AIRBAG SENSOR
ASSEMBLY. ONLY WHEN THE IGNITION SW IS ON DOES THE CURRENT FROM THE ECU–IG FUSE FLOW TO TERMINAL 1. AND THE
CURRENT FROM THE IGN FUSE TO TERMINAL 7.
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
CIG & RAD, ECU–IG OR IGN FUSE FLOWS TO TERMINAL 11 OF THE CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 1 OF THE
AIRBAG SQUIB → SQUIB → TERMINAL 2 → TERMINAL 10 OF CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 8, TERMINAL 13 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 CIG & RAD, ECU–IG OR IGN FUSE FLOWS TO TERMINAL 11 OF
THE CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 1 OF THE AIRBAG SQUIB → SQUIB →TERMINAL 2 → TERMINAL 10 OF THE
CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 3 OR 4 → TERMINAL 1 OF FRONT AIRBAG SENSOR → TERMINAL 2 →
TERMINAL 2 OR 5 OF CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 8, TERMINAL 13 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.

RADIATOR FAN AND AIR CONDITIONER (AUTOMATIC AIR CONDITIONER, FOR PUSH TYPE OF BLOWER CONTROL SW)
SYSTEM OUTLINE
1. COOLING FAN OPERATION
WHEN THE IGNITION SW IS TURNED ON, THE CURRENT FROM IGN FUSE FLOWS TO TERMINAL 3 OF RADIATOR FAN RELAY NO. 1 →
TERMINAL 4 → TERMINAL 3 OF THE A/C PRESSURE SW → TERMINAL 2 → TERMINAL 1 OF WATER TEMP. SW (FOR FANS CONTROL)
→ TERMINAL 2 (5S–FE) → GROUND, FROM TERMINAL 2 OF A/C FAN RELAY NO. 2 → TERMINAL 4 → TERMINAL 3 OF A/C PRESSURE
SW → TERMINAL 2 → TERMINAL 1 OF WATER TEMP. SW (FOR FANS CONTROL) → TERMINAL 2 (5S–FE) → GROUND, CAUSING
RELAY NO. 1 AND RELAY NO. 2 OF EACH FAN TO TURN ON.
* OPERATION AT LOW SPEED
WHEN THE A/C SW (A/C CONTROL ASSEMBLY) IS TURNED ON AND THE AIR CONDITIONER OPERATES, THE CURRENT FLOWS
FROM GAUGE FUSE FLOWS TO TERMINAL 2 OF A/C MAGNET CLUTCH RELAY → TERMINAL 3 → TERMINAL 8 OF A/C AMPLIFIER
CAUSING A/C MAGNET CLUTCH RELAY TO TURN ON.
AT THAT TIME, THE CURRENT FROM GAUGE FUSE FLOWS TO TERMINAL 4 OF A/C MAGNET CLUTCH RELAY → TERMINAL 1 →
TERMINAL 4 OF A/C MAGNET CLUTCH → GROUND, AND FROM TERMINAL 1 OF A/C MAGNET CLUTCH RELAY → TERMINAL 2 OF A/C
FAN RELAY NO. 3 → TERMINAL 3 → GROUND.
AS A RESULT, A/C MAGNET CLUTCH AND A/C FAN RELAY NO. 3 TURN ON AND THE CURRENT FLOWS FROM FL CDS FAN →
TERMINAL 2 OF A/C CONDENSER FAN MOTOR → TERMINAL 1 → TERMINAL 4 OF A/C FAN RELAY NO. 3 → TERMINAL 1 → TERMINAL
1 OF A/C FAN RELAY NO. 2 → TERMINAL 5 → TERMINAL 2 OF A/C CONDENSER FAN MOTOR → TERMINAL 1 → GROUND, FLOWING
TO EACH FAN MOTOR IN SERIES, CAUSING THE COOLING 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 14.3 KG/CM2 1401 KPA, 203 PSI), THE A/C PRESSURE SW TURNS OFF.
AS A RESULT, FAN RELAY NO. 1 AND NO. 2 TURNS OFF AND THE CURRENT FLOWS FROM FL RDI FAN → TERMINAL 1 OF RADIATOR
FAN RELAY NO. 1 → TERMINAL 2 → TERMINAL 2 OF RADIATOR FAN MOTOR → TERMINAL 1 → GROUND, AND FROM FL CDS FAN →
TERMINAL 2 OF A/C CONDENSER FAN MOTOR → TERMINAL 1 → TERMINAL 4 OF A/C FAN RELAY NO. 3 → TERMINAL 1 → TERMINAL
1 OF A/C FAN RELAY NO. 2 → TERMINAL 3 GROUND, FLOWING TO EACH FAN MOTOR IN PARALLEL CAUSING THE COOLING FAN TO
ROTATE AT HIGH SPEED. WHEN THE ENGINE COOLANT TEMPERATURE BECOMES MORE THAN ABOUT 90°C (194° F), THE WATER
TEMP. SW TURNS OFF AND THE SAME OPERATION AS ABOVE IS PERFORMED.
2. HEATER BLOWER MOTOR OPERATION (PUSH TYPE BLOWER CONTROL SW (W/ AUTO A/C)
CURRENT IS APPLIED AT ALL TIMES THROUGH THE HEATER FUSE TO TERMINAL 5 OF HEATER RELAY. WHEN THE IGNITION SW IS
TURNED ON, CURRENT FLOWS THROUGH GAUGE FUSE TO TERMINAL 3 OF HEATER RELAY → TERMINAL 1 → TERMINAL HR OF
A/C AUTO AMPLIFIER. AT THE SAME TIME, CURRENT ALSO FLOWS FROM GAUGE FUSE TO TERMINAL 5 OF A/C BLOWER CONTROL
RELAY → TERMINAL 7 → TERMINAL FR OF A/C AUTO AMPLIFIER.
* LOW SPEED OPERATION (OPERATION AT MANUAL)
WHEN THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO LOW POSITION, SIGNALS ARE INPUT FROM TERMINAL C3 OF
THE A/C CONTROL ASSEMBLY, TERMINAL BSW OF THE A/C AUTO AMPLIFIER AND TERMINAL B4 OF THE A/C AUTO AMPLIFIER AND
TERMINAL B4 OF THE A/C CONTROL ASSEMBLY TO TERMINAL 10 OF THE A/C AUTO AMPLIFIER, CAUSING THE A/C AUTO
AMPLIFIER TO OPERATE.
CURRENT FLOWING TO TERMINAL HR OF A/C AUTO AMPLIFIER FLOWS TO TERMINAL GND OF A/C AUTO AMPLIFIER → GROUND
AND TURNS THE HEATER RELAY ON.
THIS CAUSES THE CURRENT TO TERMINAL 5 OF THE HEATER RELAY TO FLOW TO TERMINAL 4 OF HEATER RELAY → TERMINAL 2
OF BLOWER MOTOR → MOTOR → TERMINAL 1 → TERMINAL 1 OF BLOWER RESISTOR → TERMINAL 4 → GROUND, CAUSING THE
BLOWER MOTOR TO ROTATE AT LOW SPEED.
* HIGH SPEED OPERATION (OPERATION AT MANUAL)
WHEN THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO HI POSITION, SIGNALS ARE INPUT FROM TERMINAL C3 OF A/C
CONTROL ASSEMBLY, TERMINAL BSW OF A/C AUTO AMPLIFIER AND TERMINAL B9 OF A/C CONTROL ASSEMBLY TO TERMINAL HI
OF A/C AUTO AMPLIFIER, CAUSING THE A/C AUTO AMPLIFIER TO OPERATE.
CURRENT TO TERMINAL HR OF THE AUTO AMPLIFIER THEN FLOWS TO TERMINAL GND OF A/C AUTO AMPLIFIER → GROUND,
TURNING THE HEATER RELAY ON.
AT THE SAME TIME, CURRENT FLOWING TO TERMINAL 5 OF THE A/C RELAY BOX FLOWS TO TERMINAL 7 OF A/C RELAY BOX →
TERMINAL FR OF A/C AUTO AMPLIFIER → TERMINAL GND → GROUND, CAUSING THE BLOWER MOTOR TO ROTATE AT HIGH
SPEED.
154
* MEDIUM SPEED OPERATION (OPERATION AT MANUAL M1, M2)
WHEN THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO M1 POSITION, A SIGNAL IS INPUT FROM TERMINAL B3 OF A/C
CONTROL ASSEMBLY TO TERMINAL M1 OF A/C AUTO AMPLIFIER
THIS CAUSES TO CURRENT FLOWING TO TERMINAL HR OF THE A/C AUTO AMPLIFIER TO FLOW TO TERMINAL GND OF A/C AUTO
AMPLIFIER → GROUND AND TURNS THE HEATER RELAY ON. SIMULTANEOUSLY, CURRENT FLOWING FROM TERMINAL BLW OF A/C
AUTO AMPLIFIER TO TERMINAL 3 OF A/C POWER TRANSISTOR → TERMINAL 2 → GROUND CAUSES CURRENT FLOWING TO THE
BLOWER MOTOR TO FLOW TO TERMINAL 5 OF HEATER RELAY → TERMINAL 4 → TERMINAL 2 OF BLOWER MOTOR → TERMINAL 1
→ TERMINAL 1 OF POWER TRANSISTOR → TERMINAL 2 → GROUND, CAUSING TO BLOWER MOTOR ROTATE AT MEDIUM LOW
SPEED.
IF THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO M2 POSITION, THE CURRENT FLOW FROM TERMINAL BLW OF THE
A/C AUTO AMPLIFIER TO TERMINAL 1 OF THE POWER TRANSISTOR BECOMES GREATER THAN FOR M1 AND CURRENT FLOWS
MORE EASILY BETWEEN TERMINAL 1 AND TERMINAL 2 OF THE POWER TRANSISTOR, SO THE BLOWER MOTOR ROTATES AT
MEDIUM HIGH SPEED.
* AUTO FUNCTION
WHEN THE AUTO SW (A/C CONTROL ASSEMBLY) IS SELECTED, THE CURRENT FLOW IS THE SAME FOR MED POSITION, BUT THE
A/C AUTO AMPLIFIER DECIDES THE APPROPRIATE AIR FLOW VOLUME ACCORDING TO THE SET TEMPERATURE AND TO INPUT
SIGNALS FROM EACH SENSOR. BY CONTROLLING THE CURRENT FLOW FROM TERMINAL BLW OF THE A/C AUTO AMPLIFIER TO
TERMINAL 3 OF POWER TRANSISTOR → TERMINAL 2 → GROUND, THE A/C AUTO AMPLIFIER CONTROLS THE BLOWER MOTOR
STEPLESSLY.
3. OPERATION OF RECIRC/FRESH CONTROL SERVO MOTOR
(SWITCHING FROM FRESH TO RECIRC)
WITH IGNITION SW TURNED ON. THE CURRENT FLOWS FROM GAUGE FUSE TO TERMINAL 1 OF RECIRC/FRESH CONTROL SERVO
MOTOR. WHEN THE RECIRC/FRESH SW IS SWITCHED TO THE RECIRC SIDE, TO CURRENT FLOWS FROM TERMINAL 1 OF
RECIRC/FRESH CONTROL SERVO MOTOR → TERMINAL 2 → TERMINAL A18 OF A/C CONTROL ASSEMBLY → TERMINAL B5 →
TERMINAL REC IND OF A/C AUTO AMPLIFIER → TERMINAL GND → 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
1 OF RECIRC/FRESH CONTROL SERVO MOTOR → TERMINAL 3 → TERMINAL A19 OF A/C CONTROL ASSEMBLY → TERMINAL B1 →
TERMINAL FRS IND OF AUTO A/C AMPLIFIER → TERMINAL GND → 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 5 OF AIR VENT MODE CONTROL SERVO
MOTOR → TERMINAL 6 → GROUND, AND THE DAMPER MOVES TO THE POSITION OF THE MODE SELECTION SW OF THE CONTROL
ASSEMBLY SWITCH IS ON.
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 7 OF AIR VENT MODE CONTROL SERVO MOTOR TO TERMINAL A25 OF A/C
CONTROL ASSEMBLY → TERMINAL C10 → GROUND.
AS A RESULT, THE SERVO MOTOR OPERATES UNTIL THE DAMPER REACHES DEF POSITION.
WHEN THIS OCCURS THE CURRENT TO THE A/C CONTROL ASSEMBLY IS SHUT OFF AND ROTATION OF THE MOTOR STOPS.
SWITCHING TO OTHER MODES IS CONTROLLED BY THE SERVO MOTOR ACCORDING THE FOLLOWING CURRENT:
1. FOOT/DEF POSITION : THE CURRENT FLOWS FROM TERMINAL 4 OF SERVO MOTOR TO TERMINAL A11 OF A/C CONTROL
ASSEMBLY.
2. FOOT POSITION : THE CURRENT FLOWS FROM TERMINAL 3 OF SERVO MOTOR TO TERMINAL A10 OF A/C CONTROL
ASSEMBLY.
3. BI–LEVEL POSITION : THE CURRENT FLOWS FROM TERMINAL 2 OF SERVO MOTOR TO TERMINAL A9 OF A/C CONTROL
ASSEMBLY.
5. OPERATION OF AIR MIX CONTROL SERVO MOTOR
WHEN THE TEMPERATURE CONTROL VOLUME IS TURNED TO THE COOL SIDE, A SIGNAL IS INPUT TO TERMINAL TEST OF A/C
AUTO AMPLIFIER FROM TERMINAL A21 OF A/C CONTROL ASSEMBLY.
AS A RESULT, A SIGNAL IS OUTPUT FROM TERMINAL AMH OF A/C AUTO AMPLIFIER TO TERMINAL 3 OF A/C SYSTEM AMPLIFIER
AND THE CURRENT FLOWING TO TERMINAL 7 OF A/C SYSTEM AMPLIFIER FROM THE GAUGE FUSE FLOWS FROM TERMINAL 1 OF
A/C SYSTEM AMPLIFIER → TERMINAL 2 OF AIR MIX CONTROL SERVO MOTOR → TERMINAL 6 → IF A/C SYSTEM AMPLIFIER →
TERMINAL 9 → GROUND. CAUSING THE AIR MIX CONTROL SERVO MOTOR TO ROTATE.
AT THIS TIME IS INPUT THE DAMPER OPENING ANGLE FROM TERMINAL 4 OF SERVO MOTOR TO TERMINAL TP OF A/C AUTO
AMPLIFIER THIS IS USED TO DETERMINE THE DAMPER STOP POSITION AND MAINTAIN THE SET TEMPERATURE.
WHEN THE TEMPERATURE CONTROL VOLUME IS TURNED TO THE WARM SIDE, IN A/C SYSTEM AMPLIFIER THE CURRENT FLOWS
FROM SERVO MOTOR → TERMINAL 6 OF A/C SYSTEM AMPLIFIER → TERMINAL 6 OF AIR MIX CONTROL SERVO MOTOR → MOTOR
→ TERMINAL 2 → TERMINAL 1 OF A/C SYSTEM AMPLIFIER → TERMINAL 9 → GROUND, ROTATING THE MOTOR IN REVERSE AND
SWITCHING THE DAMPER FROM COOL TO WARM SIDE.

RADIATOR FAN AND AIR CONDITIONER (AUTOMATIC AIR CONDITIONER, FOR PUSH TYPE OF BLOWER CONTROL SW)
SYSTEM OUTLINE
6. AIR CONDITIONER OPERATION
THE A/C AMPLIFIER RECEIVES VARIOUS SIGNALS, THE ENGINE RPM SIGNAL FROM THE IGNITER, OUTLET TEMPERATURE SIGNAL
FROM THE A/C THERMISTER, COOLANT TEMPERATURE FROM THE WATER TEMP. SENSOR, AND THE LOCK SIGNAL FROM THE A/C
COMPRESSOR, ETC.
WHEN THE ENGINE IS STARTED AND THE A/C SW (A/C CONTROL ASSEMBLY) IS TURNED ON, A SIGNAL IS INPUT TO TERMINAL A/C
SW OF A/C AUTO AMPLIFIER FROM TERMINAL C12 OF A/C CONTROL ASSEMBLY. WHEN THIS HAPPENS, A SIGNAL IS OUTPUT FROM
TERMINAL A/C OF A/C AUTO AMPLIFIER TO TERMINAL 3 OF A/C AMPLIFIER.
AS A RESULT, THE CURRENT FLOWING FROM TERMINAL 3 OF A/C MAGNET CLUTCH RELAY TO TERMINAL 8 OF A/C AMPLIFIER
FLOWS FROM TERMINAL 15 OF A/C AMPLIFIER TO GROUND AND TURNS IN THE MAGNET CLUTCH RELAY.
BECAUSE THE MAGNET CLUTCH IS ON, THE A/C COMPRESSOR OPERATES, CAUSING THE CURRENT FLOWING FROM A/C IDLE–UP
VSV TO TERMINAL 6 OF A/C AMPLIFIER TO FLOW TO TERMINAL 15 OF A/C AMPLIFIER → GROUND, AND TURNS ON THE VSV TO
AVOID LOWERING THE ENGINE RPM 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:
∗ ENGINE HIGH RPM SIGNAL
∗ COOLANT HIGH 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 RPM AND COMPRESSOR RPM
∗ A SIGNAL THAT THE REFRIGERANT PRESSURE IS ABNORMALLY HIGH OR LOW.

RADIATOR FAN AND AIR CONDITIONER (MANUAL AIR CONDITIONER, FOR PUSH TYPE OF BLOWER CONTROL SW)
SYSTEM OUTLINE
1. COOLING FAN OPERATION
WHEN THE IGNITION SW IS TURNED ON, THE CURRENT FROM IGN FUSE FLOWS TO TERMINAL 3 OF RADIATOR FAN RELAY NO. 1 →
TERMINAL 4 → TERMINAL 3 OF THE A/C PRESSURE SW → TERMINAL 2 → TERMINAL 1 OF WATER TEMP. SW (FOR FANS CONTROL)
→ TERMINAL 2 (5S–FE) → GROUND, FROM TERMINAL 2 OF A/C FAN RELAY NO. 2 → TERMINAL 4 → TERMINAL 3 OF A/C PRESSURE
SW → TERMINAL 2 → TERMINAL 1 OF WATER TEMP. SW (FOR FANS CONTROL) → TERMINAL 2 (5S–FE) → GROUND, CAUSING
RELAY NO. 1 AND RELAY NO. 2 OF EACH FAN TO TURN ON.
* OPERATION AT LOW SPEED
WHEN THE A/C SW (A/C CONTROL ASSEMBLY) IS TURNED ON AND THE AIR CONDITIONER OPERATES, THE CURRENT FLOWS
FROM GAUGE FUSE FLOWS TO TERMINAL 2 OF A/C MAGNET CLUTCH RELAY → TERMINAL 3 → TERMINAL 8 OF A/C AMPLIFIER
CAUSING A/C MAGNET CLUTCH RELAY TO TURN ON.
AT THAT TIME, THE CURRENT FROM GAUGE FUSE FLOWS TO TERMINAL 4 OF A/C MAGNET CLUTCH RELAY → TERMINAL 1 →
TERMINAL 4 OF A/C MAGNET CLUTCH → GROUND, AND FROM TERMINAL 1 OF A/C MAGNET CLUTCH RELAY → TERMINAL 2 OF A/C
FAN RELAY NO. 3 → TERMINAL 3 → GROUND.
AS A RESULT, A/C MAGNET CLUTCH AND A/C FAN RELAY NO. 3 TURNS ON AND THE CURRENT FLOWS FROM FL CDS FAN →
TERMINAL 2 OF A/C CONDENSER FAN MOTOR → TERMINAL 1 → TERMINAL 4 OF A/C FAN RELAY NO. 3 → TERMINAL 1 → TERMINAL
1 OF A/C FAN RELAY NO. 2 → TERMINAL 5 → TERMINAL 2 OF A/C CONDENSOR FAN MOTOR → TERMINAL 1 → GROUND, FLOWING
TO EACH FAN MOTOR IN SERIES, CAUSING THE COOLING 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 14.3 KG/CM2 1401 KPA, 203 PSI), THE A/C PRESSURE SW TURNS OFF.
AS A RESULT, FAN RELAY NO. 1 AND NO. 2 TURNS OFF AND THE CURRENT FLOWS FROM FL RDI FAN → TERMINAL 1 OF RADIATOR
FAN RELAY NO. 1 → TERMINAL 2 → TERMINAL 2 OF RADIATOR FAN MOTOR → TERMINAL 1 → GROUND, AND FROM FL CDS FAN →
TERMINAL 2 OF A/C CONDENSOR FAN MOTOR → TERMINAL 1 → TERMINAL 4 OF A/C FAN RELAY NO. 3 → TERMINAL 1 TERMINAL 1
OF A/C FAN RELAY NO. 2 → TERMINAL 3 → GROUND, FLOWING TO EACH FAN MOTOR IN PARALLEL CAUSING THE → COOLING FAN
TO ROTATE AT HIGH SPEED. WHEN THE ENGINE COOLANT TEMPERATURE BECOMES MORE THAN ABOUT 90°C (194°F), THE
WATER TEMP. SW TURNS OFF AND THE SAME OPERATION AS ABOVE IS PERFORMED.
2. HEATER BLOWER MOTOR OPERATION PUSH TYPE BLOWER CONTROL SW (W/O AUTO A/C)
CURRENT IS APPLIED AT ALL TIMES THROUGH THE HEATER FUSE TO TERMINAL 5 OF HEATER RELAY. WHEN THE IGNITION SW IS
TURNED ON, CURRENT FLOWS THROUGH GAUGE FUSE TO TERMINAL 3 OF HEATER RELAY → TERMINAL 1 → TERMINAL C3 OF
A/C CONTROL ASSEMBLY.
AT THE SAME TIME, CURRENT ALSO FLOWS FROM GAUGE FUSE TO TERMINAL 5 OF A/C BLOWER CONTROL RELAY → TERMINAL 7
→ TERMINAL C1 OF A/C CONTROL ASSEMBLY, FROM TERMINAL 5 OF BLOWER CONTROL RELAY → TERMINAL 8 → TERMINAL C8
OF A/C CONTROL ASSEMBLY, AND ALSO FROM TERMINAL 5 OF BLOWER CONTROL ASSEMBLY.
* LOW SPEED OPERATION (OPERATION AT MANUAL)
WHEN THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO LOW POSITION, THE CURRENT FLOWING TO TERMINAL C3 OF
A/C CONTROL ASSEMBLY FLOWS TO TERMINAL C10 OF A/C CONTROL ASSEMBLY → GROUND AND TURNS THE HEATER RELAY
ON.
THIS CAUSES THE CURRENT FLOWING FROM THE HEATER FUSE TO TERMINAL 5 OF THE HEATER RELAY TO FLOW TO TERMINAL
4 OF HEATER RELAY → TERMINAL 4 → GROUND, CAUSING THE BLOWER MOTOR TO ROTATE AT LOW SPEED.
* HIGH SPEED OPERATION (OPERATION AT MANUAL)
WHEN THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO HI POSITION, CURRENT FLOWS FROM TERMINAL C3 OF A/C
CONTROL ASSEMBLY → TERMINAL C10 OF A/C CONTROL ASSEMBLY → GROUND AND TURNS THE HEATER RELAY ON.
AS A RESULT, THE CURRENT FLOWING TO TERMINAL C1 OF THE A/C CONTROL ASSEMBLY FLOWS TO TERMINAL C10 OF A/C
CONTROL ASSEMBLY → GROUND, TURNING THE A/C BLOWER CONTROL RELAY ON.
THIS CASE IS THE CURRENT FLOWING FROM THE HEATER FUSE TO TERMINAL 5 OF THE HEATER RELAY TO FLOW TO TERMINAL 4
OF RELAY → TERMINAL 2 OF BLOWER MOTOR → TERMINAL 1 → TERMINAL 4 OF BLOWER CONTROL RELAY → TERMINAL 3 →
GROUND, CAUSING THE BLOWER MOTOR TO ROTATE AT HIGH SPEED.
166
* MEDIUM SPEED OPERATION (OPERATION AT MANUAL M1, M2)
WHEN THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO M1 POSITION, CURRENT FLOWS FROM TERMINAL C3 OF A/C
CONTROL ASSEMBLY TO TERMINAL C10 OF A/C CONTROL ASSEMBLY → GROUND AND TURNS THE HEATER RELAY ON.
AS A RESULT, THE CURRENT FLOWING TO TERMINAL C2 OF THE A/C CONTROL ASSEMBLY FLOWS TO TERMINAL C10 OF THE A/C
CONTROL ASSEMBLY → GROUND, TURNING THE BLOWER CONTROL RELAY ON SO THAT THE CURRENT FLOWING FROM THE
HEATER FUSE TO TERMINAL 5 OF THE HEATER REALY FLOWS TO TERMINAL 4 OF HEATER RELAY → TERMINAL 2 OF BLOWER
MOTOR → TERMINAL 1 → TERMINAL 1 OF BLOWER RESISTOR → TERMINAL 2 → TERMINAL 7 OF BLOWER CONTROL RELAY →
TERMINAL 3 → GROUND, CAUSING THE BLOWER MOTOR TO ROTATE AT MEDIUM SPEED.
WHEN THE BLOWER SW (A/C CONTROL ASSEMBLY) IS MOVED TO M2 POSITION, CURRENT FLOWS FROM TERMINAL 1 OF BLOWER
MOTOR → TERMINAL 1 OF BLOWER RESISTOR → TERMINAL 3 → TERMINAL 2 OF BLOWER CONTROL RELAY → TERMINAL 3 →
GROUND. THIS CURRENT FLOW FROM BLOWER MOTOR TO GROUND IS GREATER THAN AT M1 POSITION, SO THE BLOWER
MOTOR ROTATES AT MEDIUM HIGH SPEED.
3. OPERATION OF RECIRC/FRESH CONTROL SERVO MOTOR
(SWITCHING FROM FRESH TO RECIRC)
WITH IGNITION SW TURNED ON, THE CURRENT FLOWS FROM GAUGE FUSE TO TERMINAL 1 OF RECIRC/FRESH CONTROL SERVO
MOTOR. WHEN THE RECIRC/FRESH SW IS SWITCHED TO THE RECIRC SIDE, THE CURRENT FLOWS FROM TERMINAL 1 OF
RECIRC/FRESH CONTROL SERVO MOTOR → TERMINAL 2 → TERMINAL A18 OF RECIRC/FRESH CONTROL SERVO MOTOR →
TERMINAL C10 → 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
1 OF RECIRC/FRESH CONTROL SERVO MOTOR → TERMINAL 3 → TERMINAL C10 OF A/C CONTROL ASSEMBLY → 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.
