Power Window Motor: Description and Operation

With the Ignition SW turned ON, Current flows through the ECU-IG fuse --> TERMINAL B-7 of the Theft Deterrent ECU --> TERMINAL B-6 --> 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 PWR fuse flows to TERMINAL 3 of the relay --> TERMINAL 4 of the Power Window master SW. TERMINAL 3 of the Power Window SW.

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 --> to Ground and causes the Power Window Motor to rotate in the up direction. The Window ascends only while the SW is being pulled up.
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 --> TERMINAL 10 of the master SW --> TERMINAL 8 --> to 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 flow 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 flow 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 (passengers) pulled to the up side, Current flowing from TERMINAL 3 of the Power Window control SW flows to TERMINAL 5 of the Power Window SW --> TERMINAL 1 of the Power Window Motor --> TERMINAL 2 --> TERMINAL 1 of the Power Window SW --> TERMINAL 2 --> TERMINAL 7 of the master SW --> TERMINAL 8 --> 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 descends, the Current flowing to the Motor flows in the opposite direction, from TERMINAL 2 to TERMINAL 1, 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 can not be Operated and Window lock occurs.

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 B-9 of the ECU or DOME fuse to TERMINAL A-1 of the ECU --> TERMINAL B-6 --> TERMINAL 1 of Power Main relay --> TERMINAL 2 --> to GROUND for about 60 seconds, the same as normal Operation, the Current flows from PWR fuse --> TERMINAL 5 of the Power Main relay --> TERMINAL 3 --> TERMINAL 4 of the Power Window master SW and TERMINAL 3 of the Power Window SW. 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 TERMINALS A-7 or A-19 of Theft Deterrent ECU. As a result, the ECU turned OFF and up and down movement of the Power Window stops.
