TO TERMINAL (A) 6 THROUGH THE HEADLIGHT RELAY COIL.
1. NORMAL LIGHTING OPERATION
(TURN TAILLIGHT ON)
WITH LIGHT CONTROL SW TURNED TO TAIL POSITION, A SIGNAL IS INPUT INTO TERMINAL (A) 4 OF THE INTEGRATION RELAY. DUE
TO THIS SIGNAL, THE CURRENT FLOWING TO TERMINAL (A) 5 OF THE RELAY FLOWS TO TERMINAL (A) 4 " TERMINAL 2 OF THE
LIGHT CONTROL SW " TERMINAL 11 " TO GROUND, AND TAILLIGHT RELAY CAUSES TAILLIGHTS TO TURN ON.
(TURN HEADLIGHT ON)
WITH LIGHT CONTROL SW TURNED TO HEAD POSITION, A SIGANL IS INPUT INTO TERMINAL (A) 4 AND (A) 7 OF THE INTEGRATION
RELAY. DUE TO THIS SIGNAL, THE CURRENT FLOWING TO TERMINAL (A) 6 OF THE RELAY FLOWS TO TERMINAL (A) 7 " 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 THE 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) 5 OF THE RELAY TO TERMINAL (A) 4 IN TAILLIGHT CIRCUIT AND FROM TERMINAL (A) 6 TO
TERMINAL (A) 7 IN HEADLIGHT CIRCUIT.
AS A RESULT, ALL LIGHTS ARE TURNED OFF AUTOMATICALLY.

POWER WINDOW
WITH THE IGNITION SW TURNED ON, CURRENT FLOWS THROUGH THE ECU±IG FUSE "TERMINAL (A)7 OF THE THEFT
DETERRENT ECU "TERMINAL (A)6 "TERMINAL 1 OF THE POWER MAIN RELAY "TERMINAL 2 "GROUND, THIS ACTIVATES THE
RELAY AND THE CURRENT FLOWING TO TERMINAL 5 OF THE RELAY FROM DOOR FUSE FLOWS TO TERMINAL 3 OF THE RELAY "
TERMINAL 4 OF THE POWER WINDOW MASTER SW AND TERMINAL 4 OF THE POWER WINDOW CONTROL SW RH.
1. MANUAL OPERATION (DRIVER'S WINDOW)
WITH THE IGNITION SW TURNED ON AND WITH THE POWER WINDOW MASTER SW (DRIVER'S) IN UP POSITION, THE CURRENT
FLOWING TO TERMINAL 4 OF THE POWER WINDOW MASTER SW FLOWS TO TERMINAL 10 OF THE MASTER SW "TERMINAL 1 OF
THE POWER WINDOW MOTOR "TERMINAL 2 "TERMINAL 9 OF THE MASTER SW "TERMINAL 8 "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 4 OF THE POWER WINDOW MASTER SW TO TERNINAL 9 OF THE
MASTER SW CAUSES THE FLOW OF CURRENT FROM TERMINAL 2 OF THE POWER WINDOW MOTOR "TERMINAL 1 "TERMINAL
10 OF THE MASTER SW "TERMINAL 8 "GROUND, FLOWING IN THE OPPOSITE DIRECTION TO MANUAL UP OPERATION AND
CAUSING THE MOTOR TO ROTATE IN REVERSE, LOWERING THE WINDOW.
2. DRIVER'S WINDOW AUTO DOWN OPERATION
WHEN THE DRIVER'S WINDOW SW IS PUSHED STRONGLY ON THE DOWN SIDE, THE CURRENT FLOWING TO TERMINAL 4 OF THE
POWER WINDOW MASTER SW FLOWS TO THE DOWN CONTACT POINT AND AUTO DOWN CONTACT POINT OF THE DRIVER'S SW.
THIS ACTIVATES THE RELAY (DOWN SIDE) INSIDE THE POWER WINDOW MASTER SW, AND THE HOLD CIRCUIT ALSO TURNS ON AT
THE SAME TIME, SO THE RELAY (DOWN SIDE) REMAINS ACTIVATED EVEN WHEN THE SW IS RELEASED.
CURRENT FLOWS AT THIS TIME FROM TERMINAL 4 OF THE POWER WINDOW MASTER SW "TERMINAL 9 "TERMINAL 2 OF
POWER WINDOW MOTOR "TERMINAL 1 "TERMINAL 10 OF POWER WINDOW MASTER SW "TERMINAL 8 "GROUND, SO THE
MOTOR CONTINUES TO OPERATE UNTIL THE DRIVER'S WINDOW IS FULLY DOWN.
WHEN THE DRIVER'S WINDOW FINISHES DOWN OPERATION THE HOLD CIRCUIT GOES OFF, SO THE RELAY (DOWN SIDE) ALSO
TURNS OFF. THIS STOPS THE CURRENT FLOWING FROM TERMINAL 4 OF THE POWER WINDOW MASTER SW TO TERMINAL 9, SO
THE POWER WINDOW MOTOR STOPS AND AUTO DOWN OPERATION STOPS.
WHEN THE DRIVER'S SW IS PULLED ON THE UP SIDE DURING AUTO DOWN OPERATION, THE HOLD CIRCUIT IS TURNED OFF SO
CURRENT FLOWS FROM TERMINAL 4 OF THE POWER WINDOW MASTER SW TO TERMINAL 9 IS CUT OFF AND THE POWER
WINDOW MOTOR STOPS. IF THE SW REMAINS PULLED UP, THE RELAY (UP SIDE) IS ACTIVATED, SO CURRENT FLOWS FROM
TERMINAL 4 OF THE POWER WINDOW MASTER SW "TERMINAL 10 "TERMINAL 1 OF POWER WINDOW MOTOR "TERMINAL 2 "
TERMINAL 9 "TERMINAL 8 "GROUND, THE POWER WINDOW MOTOR ROTATES IN THE UP DIRECTION AND MANUAL UP
OPERATION OCCURS WHILE THE SW IS PULLED UP.
3. MANUAL OPERATION BY POWER WINDOW SW (PASSENGER'S WINDOW)
WITH POWER WINDOW SW (PASSENGER'S) PULLED TO THE UP SIDE, CURRENT FLOWING FROM TERMINAL 4 OF THE POWER
WINDOW CONTROL SW FLOWS TO TERMINAL 1 OF THE POWER WINDOW SW "TERMINAL 2 OF THE POWER WINDOW MOTOR "
TERMINAL 1 "TERMINAL 3 OF THE POWER WINDOW SW "TERMINAL 5 "TERMINAL 7 OF THE MASTER SW "TERMINAL 8 "
GROUND AND CAUSES THE POWER WINDOW MOTOR (PASSENGER'S) TO ROTATE IN THE UP DIRECTION. UP OPERATION
CONTINUES ONLY WHILE THE POWER WINDOW SW IS PULLED TO THE UP SIDE. WHEN THE POWER WINDOW SW (PASSENGER'S)
IS PULLED TO THE DOWN SIDE, THE CURRENT FLOWING TO THE MOTOR FLOWS IN THE OPPOSITE DIRECTION, FROM TERMINAL 1
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 8 OF
THE POWER WINDOW MASTER SW IS NOT GROUNDED AND THE MOTOR DOES NOT ROTATE, SO THE PASSENGER'S WINDOW
CANNOT BE OPERATED AND WINDOW LOCK OCCURS. FURTHERMORE, REAR LH, RH WINDOW OPERATE THE SAME AS THE
ABOVE CIRCUIT.
4. KEY OFF POWER WINDOW OPERATION
WITH THE IGNITION SW TURNED FROM ON TO OFF, THE THEFT DETERRENT ECU OPERATES AND CURRENT FLOWS FROM DOOR
FUSE TO TERMINAL (A)9 OF THE ECU OR DOME FUSE TO TERMINAL (B)1 OF THE ECU "TERMINAL (A)6 "TERMINAL 1 OF POWER
MAIN RELAY "TERMINAL 2 "GROUND FOR ABOUT 60 SECONDS. THE SAME AS NORMAL OPERATION, THE CURRENT FLOWS
FROM DOOR FUSE "TERMINAL 5 OF THE POWER MAIN RELAY "TERMINAL 3 "TERMINAL 4 OF THE POWER WINDOW MASTER
SW AND TERMINAL 4 OF THE POWER WINDOW CONTROL SW RH. AS A RESULT, FOR ABOUT 60 SECONDS AFTER THE IGNITION SW
IS TURNED OFF, THE FUNCTIONING OF THIS RELAY MAKES IT POSSIBLE TO RAISE AND LOWER THE POWER WINDOW. ALSO, BY
OPENING THE FRONT DOOR (DOOR OPEN DETECTION SW ON) WITHIN ABOUT 60 SECONDS AFTER TURNING THE IGNITION SW TO
OFF, A SIGNAL IS INPUT TO TERMINAL (B)19, (B)7 OF THEFT DETERRENT ECU. AS A RESULT, THE ECU TURNED OFF AND UP AND
DOWN MOVEMENT OF THE POWER WINDOW STOPS.
