POWER WINDOW
SYSTEM OUTLINE
WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS THROUGH THE ECU-IG FUSE TO
OF THE THEFT DETERRENT AND DOOR LOCK CONTROL ECU
MAIN RELAY TERMINAL 2
TERMINAL 5 OF THE RELAY FROM DOOR FUSE FLOWS TO TERMINAL 3 OF THE RELAY
POWER WINDOW MASTER SW AND
1. MANUAL OPERATION (DRIVER'S WINDOW)
WITH THE IGNITION SW TURNED ON AND WITH THE POWER WINDOW MASTER SW (DRIVER'S) AT UP POSITION,
THE CURRENT FLOWING TO TERMINAL 4 OF THE POWER WINDOW MASTER SW FLOWS TO TERMINAL 10 OF
THE MASTER SW TERMINAL 1
MASTER SW TERMINAL 8
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
TERMINAL 9 OF THE MASTER SW CAUSES THE FLOW OF CURRENT FROM TERMINAL 2 OF THE POWER
WINDOW MOTOR TERMINAL 1
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 2 OF POWER WINDOW MOTOR
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 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 (UPSIDE)
IS ACTIVATED, SO CURRENT FLOWS FROM TERMINAL 4 OF THE POWER WINDOW MASTER SW
TERMINAL 1 OF THE POWER WINDOW MOTOR
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 (FRONT RH WINDOW)
WITH POWER WINDOW SW (FRONT RH) 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
THE POWER WINDOW MOTOR
TERMINAL 7 OF THE MASTER SW
(FRONT RH) 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 (FRONT RH) 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 AND DOOR LOCK CONTROL ECU
AND CURRENT FLOWS FROM DOOR FUSE TERMINAL (A) 9 OF THE ECU OR DOME FUSE TO TERMINAL (B)1 OF
THE ECU TERMINAL (A) 6
SECONDS. THE SAME AS NORMAL OPERATION, THE CURRENT FLOWS FROM DOOR FUSE
THE POWER MAIN RELAY
4 OF THE POWER WINDOW CONTROL SW RH. AS A RESULT, FOR ABOUT 60 SECONDS AFTER THE IGNITION SW
IS TURNED. 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 ED) WITHIN ABOUT 60
SECONDS AFTER TURNING THE IGNITION SW TO OFF, A SIGNAL IS INPUT TO TERMINAL (B) 19, (B) 7 OF THE
THEFT DETERRENT AND DOOR LOCK CONTROL ECU. AS A RESULT, THE ECU TURNED OFF AND UP AND DOWN
MOVEMENT OF THE POWER WINDOW STOPS.
