Auto-reverse operation
The system consists of a main power window switch and power windows on the driver and front passenger sides.
The driver's power window actuator includes a pulsator that generates pulses during operation of the actuator and sends them to the driver's window control unit. As soon as the power window control unit does not detect pulses from the pulsator, it causes the drive to stop and reverse. If the window is more than half closed, it will return to the middle position. If the window is less than half closed, it will stop and return about 5.08 cm. This is to prevent obstruction during the auto-raise operation. The auto-return operation is inactive when the switch is in the up position.
