POWER WINDOW
WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS THROUGH THE GAUGE FUSE TO TERMINAL 1 OF THE POWER MAIN
RELAY " TERMINAL 2 " TO GROUND. THIS ACTIVATES THE RELAY AND THE CURRENT FLOWING TO TERMINAL 5 OF THE RELAY
FROM POWER FUSE FLOWS TO TERMINAL 3 OF THE RELAY " TERMINAL 7 OR 8 (EX. C/P), 9 (C/P) OF THE POWER WINDOW
MASTER SW " TO TERMINAL 5 OF THE POWER WINDOW SW.
1. MANUAL OPERATION (DRIVER'S WINDOW)
WITH THE IGNITION SW TURNED ON AND WITH THE POWER WINDOW MASTER SW (MANUAL SW) IN UP POSITION. THE CURRENT
FLOWING TO TERMINAL 7 OR 8 (EX. C/P), 9 (C/P) OF THE POWER WINDOW MASTER SW FLOWS TO TERMINAL 6 (EX. C/P), 3 (C/P) OF
THE MASTER SW " TEMINAL 2 OF THE POWER WINDOW MOTOR " TERMINAL 1 " TERMINAL 13 (EX. C/P), 4 (C/P) OF THE MASTER
SW " TERMINAL 2 OR 1 (EX. C/P), 6 (C/P) " 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 7 OR 8 (EX. C/P), 9 (C/P) OF THE POWER WINDOW MASTER SW TO TERMINAL 13 (EX. C/P), 4 (C/P) OF THE MASTER
SW CAUSES THE FLOW OF CURRENT FROM TERMINAL 1 OF THE MOTOR " TERMINAL 2 " TERMINAL 6 (EX. C/P), 3 (C/P) OF THE
MASTER SW " TERMINAL 2 OR 1 (EX. C/P), 3 (C/P) " 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 AUTO SW OF THE POWER WINDOW MASTER SW IN DOWN POSITION, CURRENT
FLOWING TO TERMINAL 7 OR 8 OF THE MASTER SW FLOWS TO TERMINAL 13 (EX, C/P), 4 (C/P) OF THE MASTER SW " TERMINAL 1
OF THE POWER WINDOW MOTOR " TERMINAL 2 " TERMINAL 6 (EX. C/P), 3 (C/P) OF THE MASTER SW " TERMINAL 2 (EX. C/P), 6
(C/P) " TO GROUND, CAUSING THE MOTOR TO ROTATE TOWARDS THE DOWN SIDE THEN THE SOLENOID IN THE MASTER SW IS
ACTIVATED AND IT LOCKS THE AUTO SW BEING PUSHED, CAUSING THE MOTOR TO CONTINUE TO ROTATE IN AUTO DOWN
OPERATION. WHEN THE WINDOW HAS COMPLETELY DESENDED, THE CURRENT FLOW BETWEEN TERMINAL 6 (EX. C/P), 3 (C/P) OF
THE MASTER SW AND TERMINAL 2 (EX. C/P), 6 (C/P) INCREASES. AS A RESULT, THE SOLENOID STOPS OPERATING, THE AUTO SW
TURNS OFF AND FLOW FROM TERMINAL 7 (EX. C/P), 9 (C/P) OF THE MASTER SW TO TERMINAL 13 (EX. C/P), 4 (C/P) IS CUT OFF,
STOPPING THE MOTOR SO THAT AUTO STOP OCCURS.
3. STOPPING OF AUTO DOWN AT DRIVER'S WINDOW
HEN THE MANUAL SW (DRIVER'S) 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 6 (EX. C/P), 3 (C/P) OF THE MASTER SW " TO GROUND, SO
THE MOTOR STOPS, CAUSING AUTO DOWN OPERATION TO STOP. IF THE MASTER 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) 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 POWER WINDOW MOTOR " TERMINAL
1 " TERMINAL 4 OF THE POWER WINDOW SW " TERMINAL 3 " TERMINAL 5 (EX. C/P), 7 (C/P) OF THE MASTER SW " TERMINAL 1
OR 2 (EX. C/P), 6 (C/P) " 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 PULLED TO THE UP SIDE. WHEN THE WINDOW
DECENDS, 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 1 OR 2 (EX. C/P), 6 (C/P) 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.
FURTHERMORE REAR LH RH WINDOW OPERATE THE SAME AS THE ABOVE CIRCUIT.
5. KEY OFF POWER WINDOW OPERATION
WITH IGNITION SW TURNED FROM ON TO OFF DOOR LOCK CONTROL RELAY OPERATES AND CURRENT FLOWS FROM POWER
FUSE TO TERMINAL 8 OF THE RELAY " TERMINAL 15 " TERMINAL 1 OF POWER MAIN RELAY " TERMINAL 2 " TO GROUND FOR
ABOUT 60 SECOND. THE SAME AS NORMAL OPERATION, THE CURRENT FLOWS FROM POWER FUSE " TERMINAL 5 OF THE
POWER MAIN RELAY " TERMINAL 3 " TERMINAL 7 OR 8 (EX. C/P), TERMINAL 9 (C/P) OF THE POWER WINDOW MASTER SW AND
TERMINAL 3 OF THE POWER MAIN RELAY " TO TERMINAL 5 OF THE POWER WINDOW SW. AS A RESULT, FOR ABOUT 60 SECOND
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 SECOND AFTER
TURNING THE IGNITION SW TO OFF, A SIGNAL IS INPUT TO DOOR LOCK CONTROL RELAY. AS A RESULT, THE RELAY TURNS OFF
AND UP AND DOWN MOVEMENT OF THE POWER WINDOW STOPS.

TERMINAL 4 OF THE RELAY " TERMINAL 16 " TO GROUND AND DOOR LOCK MOTORS 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 RELAY, AND IF THE SIGNAL IS INPUT AGAIN WITHIN 3 SECONDS BY TURNING THE SW TO THE UNLOCK SIDE AGAIN,
CURRENT FLOWS TERMINAL 3 " TERMINAL 2 OF DOOR LOCK MOTORS, (EX. C/P FRONT DOOR) OR TERMINAL 5 (C/P FRONT
DOOR) OF THE DOOR LOCK MOTOR TERMINAL 1 OF THE BACK DOOR LOCK MOTOR " TERMINAL 4 OF THE DOOR LOCK MOTORS,
(EX. C/P FRONT DOOR) OR TERMINAL 7 (C/P FRONT DOOR), OF THE DOOR LOCK MOTOR TERMINAL 2 OF THE BACK DOOR LOCK

CURRENT IS APPLIED AT ALL TIMES THROUGH POWER FUSE TO TERMINAL 5 OF POWER MAIN RELAY AND ALSO THROUGH DOME
FUSE TO TERMINAL 12 OF MOON ROOF CONTROL RELAY.
WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS FROM TERMINAL 1 OF POWER MAIN RELAY " TERMINAL 2 " TO
GROUND THROUGH GAUGE FUSE. AS A RESULT, POWER MAIN RELAY IS ACTIVATED AND THE CURRENT TO TERMINAL 5 OF
POWER MAIN RELAY FLOWS FROM TERMINAL 3 OF RELAY TO TERMINAL 6 OF MOON ROOF CONTROL RELAY.
1. SLIDE OPEN OPERATION
WHEN THE IGNITION SW IS TURNED ON AND THE MOON ROOF CONTROL SW IS PUSHED TO THE OPEN POSITION, A SIGNAL IS
INPUT FROM TERMINAL 3 OF MOON ROOF CONTROL SW TO TERMINAL 1 OF MOON ROOF CONTROL RELAY. MOON ROOF LIMIT SW
NO. 2 ON AT THIS TIME.
WHEN THIS OCCURS, THE RELAY IS ACTIVATED AND THE CURRENT TO TERMINAL 6 OF MOON ROOF CONTROL RELAY FLOWS
FROM TERMINAL 5 " TERMINAL 1 OF MOON ROOF MOTOR " TERMINAL 3 " TERMINAL 4 OF MOON ROOF CONTROL RELAY "
TERMINAL 11 " TO GROUND AND ROTATES THE MOTOR TO OPEN THE MOON ROOF WHILE THE SW IS BEING PUSHED TO OPEN
POSITION.
2. SLIDE CLOSE OPERATION
WITH THE IGNITION SW TURNED ON, THE MOON ROOF COMPLETELY OPEN AND MOON ROOF LIMIT SW NO. 1 AND NO. 2 BOTH ON,
WHEN THE MOON ROOF CONTROL SW IS PUSHED TO THE CLOSE POSITION A SIGNAL IS INPUT FROM TERMINAL 6 OF MOON
ROOF CONTROL SW TO TERMINAL 2 OF MOON ROOF CONTROL RELAY.
WHEN THIS OCCURS, THE RELAY IS ACTIVATED AND THE CURRENT TO TERMINAL 6 OF MOON ROOF CONTROL RELAY FLOWS
FROM TERMINAL 4 " TERMINAL 3 OF MOON ROOF MOTOR " TERMINAL 1 " TERMINAL 5 OF MOON ROOF CONTROL RELAY "
TERMINAL 11 " TO GROUND AND ROTATES THE MOTOR TO CLOSE THE MOON ROOF WHILE THE SW IS BEING PUSHED TO CLOSE
POSITION.
MOON ROOF LIMIT SW NO. 1 TURNS OFF (LIMIT SW NO. 2 IS ON) AND A 100 MM BEFORE FULLY CLOSE POSITION, SIGNAL IS INPUT
FROM TERMINAL 1 OF LIMIT SW NO. 1 TO TERMINAL 8 OF MOON ROOF CONTROL RELAY. THIS SIGNAL ACTIVATES THE RELAY AND
STOPS CONTINUITY FROM TERMINAL 6 OF MOON ROOF CONTROL RELAY TO TERMINAL 11. AS A RESULT, THE MOON ROOF
STOPS AT THIS POSITION.
TO CLOSE THE MOON ROOF COMPLETELY, PUSHING THE MOON ROOF CONTROL SW AGAIN TO THE CLOSE SIDE CAUSES A
SIGNAL TO BE INPUT AGAIN TO TERMINAL 2 OF MOON ROOF CONTROL RELAY. THIS ACTIVATES THE RELAY AND THE MOON ROOF
WILL CLOSE AS LONG AS THE MOON ROOF CONTROL SW IS BEING PUSHED, ALLOWING THE MOON ROOF TO FULLY CLOSE.
3. TILT UP OPERATION
WHEN THE MOON ROOF CONTROL SW IS PUSHED TO TILT UP POSITION, WITH THE IGNITION SW TURNED ON AND THE MOON
ROOF COMPLETELY CLOSED (MOON ROOF LIMIT SW NO. 2 IS OFF), A SIGNAL IS INPUT FROM TERMINAL 5 OF MOON ROOF
CONTROL SW TO TERMINAL 3 OF MOON ROOF CONTROL RELAY. AS A RESULT, THE RELAY IS ACTIVATED AND THE CURRENT TO
TERMINAL 6 OF RELAY FLOWS FROM TERMINAL 4 OF RELAY " TERMINAL 3 OF MOON ROOF MOTOR " TERMINAL 1 " TERMINAL
5 OF RELAY " TERMINAL 11 TO GROUND AND ROTATES THE MOTOR SO THAT TILT UP OPERATION OCCURS AS LONG AS THE
MOON ROOF CONTROL SW IS PUSHED ON THE TILT UP SIDE.
4. TILT DOWN OPERATION
WHEN THE MOON ROOF CONTROL SW IS PUSHED TO TILT DOWN POSITION, WITH THE IGNITION SW TURNED ON AND THE MOON
ROOF TILTED UP (NO. 1 AND NO. 2 MOON ROOF LIMIT SWITCHES ARE BOTH OFF), A SIGNAL IS INPUT FROM TERMINAL 2 OF MOON
ROOF CONTROL SW TO TERMINAL 7 OF MOON ROOF CONTROL RELAY.
AS A RESULT, THE RELAY IS ACTIVATED AND THE CURRENT TO TERMINAL 6 OF RELAY FLOWS FROM TERMINAL 5 OF RELAY "
TERMINAL 1 OF MOON ROOF MOTOR " TERMINAL 3 " TERMINAL 4 OF RELAY " TERMINAL 11 " TO GROUND AND ROTATES THE
MOTOR SO THAT TILT DOWN OPERATION OCCURS AS LONG AS THE MOON ROOF CONTROL SW IS PUSHED ON THE TILT DOWN
SIDE. (DURING TILT DOWN, LIMIT SW NO. 1 IS CHANGED OFF TO ON.)
5. TILT UP REMINDER SYSTEM
WHEN THE IGNITION SW IS TURNED FROM ON TO ACC OR OFF WITH THE MOON ROOF STILL TILTED UP THE CURRENT DOES NOT
FLOW TO TERMINAL 6 OF MOON ROOF CONTROL RELAY.
THIS IS RECEIVED BY THE RELAY AS A SIGNAL THAT THE IGNITION SW IS TURNED OFF. AT THIS TIME, MOON ROOF LIMIT SW NO.1
AND NO. 2 ARE OFF, SO SIGNALS ARE INPUT TO TERMINALS 8 AND 9 OF MOON ROOF CONTROL RELAY THAT THE MOON ROOF IS
IN THE TILT OPERATION POSITION. WHEN THESE SIGNALS ARE INPUT TO THE MOON ROOF CONTROL RELAY, THE TIMER BUILT
INTO THE RELAY OPERATES.
THUS THE CURRENT TO TERMINAL 12 OF MOON ROOF CONTROL RELAY FLOWS THROUGH BUZZER OF MOON ROOF CONTROL
RELAY AND TERMINAL 11 OF MOON ROOF CONTROL RELAY TO GROUND AND THE BUZZER SOUNDS ABOUT 8 TIMES TO NOTIFY
THAT THE MOON ROOF IS STILL IN THE TILT UP CONDITION.
