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.

CURRENT IS APPLIED AT ALL TIMES THROUGH THE STOP FUSE TO TERMINAL 2 OF THE STOP LIGHT SW.
WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS FROM THE GAUGE FUSE TO TERMINAL 8 OF THE LIGHT FAILURE
SENSOR, AND ALSO FLOWS THROUGH THE REAR LIGHT WARNING LIGHT TO TERMINAL 4 OF THE LIGHT FAILURE SENSOR.
STOP LIGHT DISCONNECTION WARNING
WHEN THE IGNITION SW IS TURNED ON AND THE BRAKE PEDAL IS PRESSED (STOP LIGHT SW ON), IF THE
STOP LIGHT CIRCUIT IS OPEN, THE CURRENT FLOWING FROM TERMINAL 7 OF THE LIGHT FAILURE SENSOR
TO TERMINAL 2 CHANGES, SO THE LIGHT FAILURE SENSOR DETECTS THE DISCONNECTION AND THE
WARNING CIRCUIT OF THE LIGHT FAILURE SENSOR IS ACTIVATED.
AS A RESULT, THE CURRENT FLOWS FROM TERMINAL 4 OF THE LIGHT FAILURE SENSOR " TERMINAL 11 "
GROUND AND TURNS THE REAR LIGHT WARNING LIGHT ON. BY PRESSING THE BRAKE PEDAL, THE CURRENT
FLOWING TO TERMINAL 8 OF THE LIGHT FAILURE SENSOR KEEPS THE WARNING CIRCUIT ON HOLDING AND
THE WARNING LIGHT ON UNTIL THE IGNITION SW IS TURNED OFF.
