Auto Reverse Power Window Operation: Notes
The system is composed of the driver's MICU, passenger's MICU, door multiplex control unit (built into the power window master switch), front passenger's power window control unit (built into the front passenger's power window switch)*, and power window motors.
*: With front passenger's power window AUTO UP/AUTO DOWN Function
The driver's and front passenger's power window motors incorporate a Hall IC unit (pulser) which generates pulses during the motor's operation and sends pulses to the driver's and passenger's power window control units. As soon as the power window control units detect a change in the pulse frequency from the Hall IC unit (pulser), the power window control units make the power window motor stop and reverse. This prevents pinching your hand or fingers during auto-up operation. The auto reverse function dose not work when the power window master switch is held in the close position.
