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.
