Auto Reverse Power Window Operation: Notes

WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.

The system is composed of the driver's MICU, passenger's MICU unit, door multiplex control unit (built into the power window master switch), front passenger's power window control unit (built into the front passenger's switch), and power window motors

The driver's and front passenger's power window motors incorporate a Hall IC unit 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, 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 does not work when the power window master switch is held in the closed position
