System Description
System DescriptionAnti-pinch Power Window Operation
The system is composed of the power window master switch and the driver's power window motor.
The driver's power window motor incorporates a pulser which generates pulses during the motor's operation and sends the pulses to the driver's power window control unit. As soon as the power window control unit detects no pulses from the pulser, the driver's power window control unit makes the power window motor stop and reverse. If the window is more than halfway closed, it will reverse to half open position. If window is less than halfway closed, it will stop and reverse about 2 inches. This is to prevent pinching your hand or fingers during auto-up operation. The anti-pinch is not active when the switch is held in the up position.
Key Cylinder Operation
With the key inserted in the driver's door key cylinder, turn the key in either direction and release it, turn it a second time and hold it within 10 seconds to operate the windows (clockwise to open, counterclockwise to close). The windows stop moving when the key is released. The anti-pinch operation is not active when closing the windows with the key cylinder. The key cylinder switch will not active until the key is removed from the ignition and the driver's door is opened. Opening the driver's cancels the key off timer.
Keyless Operation
By pressing the UNLOCK button of the keyless transmitter a second time and hold within 10 seconds, the windows open. The windows stop moving when the UNLOCK button is released. The windows do not close with the LOCK button. The keyless window operation with the remotes will not work until the key has been removed from the ignition, and the driver's door has been opened. This cancels the key off timer.
Resetting the Power Window Control Unit
Resetting the driver's power window is required when any of the following have occurred:
- Power window regulator replacement or repair
- Power window motor replacement or repair
- Window run channel replacement or repair
- Driver's door glass replacement or repair
- Power is removed from a power window control unit while the power window timer is ON.
