VOLTAGE IS ALWAYS APPLIED FROM THE MAIN FUSE, THROUGH THE HEADLIGHT RELAY (COIL SIDE) TO
TERMINAL 5 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN), TERMINAL 6 OF THE INTEGRATION RELAY,
TERMINAL 14 OF THE DIMMER SW, DIMMER RELAY (DAYTIME RUNNING LIGHT RELAY NO. 2) (COIL SIDE), TO
TERMINAL 17 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN). WHEN THE IGNITION SW IS TURNED ON, VOLTAGE
FROM THE GAUGE FUSE IS APPLIED TO TERMINAL 2 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN).
1. DAYTIME RUNNING LIGHT OPERATION
WHEN THE ENGINE STARTS, VOLTAGE FROM TERMINAL `L' OF THE GENERATOR IS APPLIED TO TERMINAL 11 OF
THE DAYTIME RUNNING LIGHT RELAY (MAIN). IF THE PARKING BRAKE LEVER IS PULLED UP (PARKING BRAKE SW
ON) AT THIS TIME, THE DAYTIME RUNNING LIGHT SYSTEM DOES NOT OPERATE. WHEN THE PARKING BRAKE IS
RELEASED (PARKING BRAKE SW OFF), A SIGNAL IS OUTPUT FROM TERMINAL 1 OF THE PARKING BRAKE SW TO
TERMINAL 8 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN). THIS ACTIVATES THE DAYTIME RUNNING LIGHT
RELAY (MAIN), TURNING ON THE DIMMER RELAY (DAYTIME RUNNING LIGHT RELAY NO. 2). CURRENT ALSO FLOWS
FROM THE MAIN FUSE TO THE DIMMER RELAY (DAYTIME RUNNING LIGHT RELAY NO. 2) (POINT SIDE) " HEAD
(LH-UPR) FUSE " HEADLIGHT HI LH " HEADLIGHT HI RH " TERMINAL (A)5 OF THE DAYTIME RUNNING LIGHT
RELAY NO. 3 " TERMINAL (A)3 " GROUND, CAUSING THE HEADLIGHTS TO LIGHT UP AT APPROX. 20% OF THEIR
NORMAL BRIGHTNESS.
ONCE THE DAYTIME RUNNING LIGHT RELAY (MAIN) HAS BEEN ACTIVATED AND THE HEADLIGHTS LIGHT UP, THE
HEADLIGHTS REMAIN ON EVEN IF THE PARKING BRAKE LEVER IS ENGAGED AGAIN (PARKING BRAKE SW ON).
2. HEADLIGHT OPERATION
WHEN THE LIGHT CONTROL SW IS AT HEAD POSITION AND THE DIMMER SW AT LOW POSITION, CURRENT FLOWS
FROM THE HEADLIGHT RELAY (COIL SIDE) TO TERMINAL 3 OF THE INTEGRATION RELAY " TERMINAL 4 "
TERMINAL 13 OF THE LIGHT CONTROL SW " TERMINAL 11 " GROUND, ACTIVATING THE HEADLIGHT RELAY.
THIS CAUSES THE CURRENT TO FLOW FROM THE HEADLIGHT RELAY (POINT SIDE) TO THE HEAD LWR FUSE "
HEADLIGHT LO " GROUND, CAUSING THE HEADLIGHTS TO LIGHT UP AT NORMAL BRIGHTNESS. SIMUTANEOUSLY,
CURRENT FLOWS FROM THE DRL FUSE " DAYTIME RUNNING LIGHT RELAY NO. 3 (COIL SIDE) " GROUND,
ACTIVATING RELAY NO. 3.
WHEN THE DIMMER SW IS AT HIGH POSITION, TERMINAL 12 OF THE DIMMER SW OUTPUTS A SIGNAL TO
TERMINAL 16 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN) TO ACTIVATE IT. THIS TURNS ON DIMMER RELAY
(DAYTIME RUNNING LIGHT RELAY NO. 2). SO CURRENT FLOWS FROM THE DIMMER RELAY (DAYTIME RUNNING
LIGHT RELAY NO. 2) (POINT SIDE) TO THE HEAD (LH-UPR) FUSE " HEADLIGHT HI LH " DAYTIME RUNNING LIGHT
NO. 3 (POINT SIDE) " GROUND, AND FROM THE HEAD (RH-UPR) FUSE " DAYTIME RUNNING LIGHT RELAY NO. 3
(POINT SIDE) " HEADLIGHT HI RH " DAYTIME RUNNING LIGHT RELAY NO. 3 (POINT SIDE) " GROUND, CAUSING
THE HEADLIGHTS TO OPERATE AT HI.
WHEN THE DIMMER SW IS AT FLASH POSITION, CURRENT FROM THE HEADLIGHT RELAY (COIL SIDE) FLOWS TO
TERMINAL 14 OF THE DIMMER SW " TERMINAL 9 " GROUND, ACTIVATING THE RELAY. SIMULTANEOUSLY,
CURRENT FROM THE HEADLIGHT RELAY (POINT SIDE) FLOWS TO HEADLIGHT LO, LIGHTING UP HEADLIGHT LO
AND ACTIVATING DAYTIME RUNNING LIGHT RELAY NO. 3. THEN TERMINAL 12 OF THE DIMMER SW OUTPUTS A
SIGNAL TO TERMINAL 16 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN), ACTIVATING THE DAYTIME RUNNING
LIGHT RELAY (MAIN) SO THAT CURRNET FLOWS TO HEADLIGHT HI LIKE IT DOES FOR HIGH POSITION. THIS
CAUSES ALL HEADLIGHTS TO LIGHT UP.

WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS TO TERMINAL 7 OF THE INTEGRATION RELAY
THROUGH GAUGE FUSE. VOLTAGE IS APPLIED AT ALL TIMES TO TERMINAL (A) 2 OF THE INTEGRATION RELAY
THROUGH THE TAILLIGHT RELAY COIL SIDE, AND TO TERMINAL (A) 3 THROUGH THE HEADLIGHT RELAY COIL
SIDE.
1. NORMAL LIGHTING OPERATION

WITH THE LIGHT CONTROL SW TURNED TO TAIL POSITION, A SIGNAL IS INPUT INTO TERMINAL (A) 1 OF THE
INTEGRATION RELAY. DUE TO THIS SIGNAL, THE CURRENT FLOWING TO TERMINAL (A) 2 OF THE RELAY FLOWS TO
TERMINAL (A) 1 " TERMINAL 2 OF THE LIGHT CONTROL SW " TERMINAL 11 " TO GROUND, AND TAILLIGHT
RELAY CAUSES TAILLIGHTS TO TURN ON.

WITH THE LIGHT CONTROL SW TURNED TO HEAD POSITION, A SIGNAL IS INPUT INTO TERMINALS (A) 1 AND (A) 4
OF THE INTEGRATION RELAY. DUE TO THIS SIGNAL, THE CURRENT FLOWING TO TERMINAL (A) 3 OF THE RELAY
FLOWS TO TERMINAL (A) 4 " TERMINAL 13 OF THE LIGHT CONTROL SW " TERMINAL 11 " TO GROUND IN THE
HEADLIGHT CIRCUIT, AND CAUSES TAILLIGHT AND HEADLIGHT RELAY TO TURN THE LIGHTS ON. THE TAILLIGHT
CIRCUIT IS SAME AS ABOVE.
2. LIGHT AUTO TURN OFF OPERATION
WITH LIGHT ON AND IGNITION SW TURNED OFF (INPUT SIGNAL GOES TO TERMINAL 7 OF THE RELAY), WHEN THE
DRIVER'S DOOR IS OPENED (INPUT SIGNAL GOES TO TERMINAL 6 OF THE RELAY), THE RELAY OPERATES AND
THE CURRENT IS CUT OFF WHICH FLOWS FROM TERMINAL (A) 2 OF THE RELAY TO TERMINAL (A) 1 IN TAILLIGHT
CIRCUIT AND FROM TERMINAL (A) 3 TO TERMINAL (A) 4 IN HEADLIGHT CIRCUIT.
AS A RESULT, ALL LIGHTS ARE TURNED OFF AUTOMATICALLY.

WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS TO TERMINAL 2 OF THE 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
TERMINAL 1 OF THE REAR WIPER RELAY FLOWS TO TERMINAL 3 OF THE RELAY "TERMINAL 1 OF THE REAR
WIPER AND WASHER SW "TERMINAL 16 "TO GROUND. THUS, THE RELAY COIL IS ACTIVATED AND THE
CURRENT TO TERMINAL 1 OF THE RELAY FLOWS TO "TERMIANL LH " TERMINAL LH 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 CHANGING 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 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.
