System Description

System Description

The driver's window will stop and automatically open if you pinch your hand or something during auto-up operation. The system is composed of the power window master switch, the power window control unit and the driver's window motor.




The power window motor incorporates a pulser which generates pulses during the motor's operation and sends the pulses to the power window control unit. As soon as the power window control unit detects no pulses from the pulser, the control unit makes the power window motor stop and reverse.

Resetting the Power Window Control Unit

Resetting the power window control unit is required after performing the following procedures

- Disconnecting the battery.
- Removing the No. 1 (20 A) fuse in the driver's under-dash fuse/relay box.
- Disconnecting the 18P connector from the power window control unit.
- Removing the window regulator, glass or glass run channel.
- Disconnecting the driver's door wire harness.

1. Turn the ignition switch OFF, then back ON (II).
2. Move the driver's window all the way down by holding the driver's switch firmly down to the second detent, when the window reaches the bottom, hold the driver's window switch in the AUTO DOWN position for 2 seconds.
3. Move the driver's window all the way up without stopping by holding the driver's switch firmly up to the second Detent, when the window reaches the top, hold the driver's window switch in the AUTO UP position for 2 seconds.

If the window does not work in AUTO, reset the power window master switch according to the above procedures again.
