Windows: Description and Operation

With the ignition SW turned ON, current flows through the GAUGE fuse to TERMINAL 7 of the integration relay to TERMINAL (A) 13 to TERMINAL 1 of the power main relay to TERMINAL 2 to GROUND, this activates the relay and the current flowing to TERMINAL 5 of the relay from the PWR fuse flows to TERMINAL 3 of the relay to TERMINAL 10 and 11 of the power window master SW.

1. MANUAL OPERATION (DRIVER'S WINDOW)
With the ignition SW turned ON and with the power window master SW in UP position, the current flowing from TERMINAL 10 and 11 of the master SW flows to TERMINAL 1 of the master SW to TERMINAL 1 of the power window motor to TERMINAL 2 to TERMINAL 5 of the master SW to TERMINAL 3 and 4 to GROUND and causes the power window motor to rotate in the up direction. The window ascends only while the master SW is being pushed.

In down operation, the flow of current from TERMINAL 10 and 11 of the master SW to TERMINAL 5 of the master SW causes the flow of current from TERMINAL 2 of the power window motor to TERMINAL 1 to TERMINAL 1 of the master SW to TERMINAL 3 and 4 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 (DRIVER'S WINDOW)
With the ignition SW turned ON and with the power window master SW is pushed strongly to the down side, the current flowing to TERMINAL 10 and 11 of the master SW flows to the down contact point and auto down contact point of the master SW.

This activates the relay (Down side) inside the master SW and the hold circuit also turns on at the same time, so the relay (Down side) remains activated even when the master SW is released.

Current flows at this time from TERMINAL 10 and 11 of the master SW to TERMINAL 5 to TERMINAL 2 of the power window motor to TERMINAL 1 to TERMINAL 1 of the master SW to TERMINAL 3 and 4 to GROUND, so the motor continues to operate until the front LH window is fully down.

When the front LH window finishes down operation and the hold circuit goes off, so the relay (Down side) also turns OFF. This stops the current flowing from TERMINAL 10 and 11 of the master SW to TERMINAL 5, so the power window motor stops and auto down operation stops.

When the master SW is pulled to the up side during auto down operation, the hold circuit is turned OFF so the current flowing from TERMINAL 10 and 11 of the master SW to TERMINAL 5 is out off and the power window motor stops. If the master SW remains pulled up the relay (Up side) is activated, so current flows from TERMINAL 10 and 11 of the master SW to TERMINAL 1 to TERMINAL 1 of the power window motor to TERMINAL 2 to TERMINAL 5 to TERMINAL 3 and 4 to GROUND, the power window motor rotates in the up direction and manual up operation occurs while the master SW is pulled up.

3. MANUAL OPERATION (PASSENGER'S WINDOW)
With the power window control SW front RH pulled to the up side, the current flowing from TERMINAL 4 of the power window control SW flows to TERMINAL 3 of the power window control SW to TERMINAL 2 of the power window motor to TERMINAL 1 to TERMINAL 1 of the power window control SW to TERMINAL 2 to TERMINAL 6 of the power window master SW to TERMINAL 3 and 4 to GROUND and causes the power window motor front RH to rotate in the up direction. The 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 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 front RH window becomes open.

As a result, even if Open/Closed operation of the front RH window is tried, the current from TERMINAL 3 and 4 of the master SW is not grounded and the motor does not rotate, so the front RH window can not 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 integration relay operates and current flows from the DOOR fuse to TERMINAL (A) 12 of the integration relay and the DOME fuse to TERMINAL 1 of the integration relay to TERMINAL (A) 13 to TERMINAL 1 of the power main relay to TERMINAL 2 to GROUND for about 60 seconds. The same as normal operation, the current flows from the PWR fuse to TERMINAL 5 of the power main relay to TERMINAL 3 to TERMINAL 10 and 11 of the power window master SW and TERMINAL 4 of the power window control 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 doors (Door open detection SW ON) within about 60 seconds after turning the ignition SW to OFF, a signal is input to TERMINAL 6 or (A) 10 of the integration relay. As a result, the relay turned OFF, and up and down movement of the power window stops.
