Anti-pinch Power Window Operation




The system is composed of the power window master switch, front passenger's power window switch, front passenger's power window control unit and the driver's and front passenger's power window motors.

Driver's Window
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. 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.

Front Passenger's Window
The front passenger's power window motor incorporates a pulser which generates pulses during the motor's operation and sends the pulses to the front passenger's power window control unit. As soon as the power window control unit detects no pulses from the pulser, the front passenger's power window control unit makes the power window motor stop and reverse. 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 a second time and hold it within 15 seconds to operate the windows and moonroof (clockwise to open, counterclockwise to close). The windows and moonroof stop moving when the key is released. The anti-pinch operation is not active when closing the windows and moonroof with the key cylinder.

Keyless Operation
By pressing the UNLOCK button of the keyless transmitter a second time and hold within 15 seconds, the windows and moonroof open. The windows and moonroof stop moving when the UNLOCK button is released. The windows do not close with the LOCK button.
