System Description
WARNING: This page is about a different car, the 2006 Acura MDX, 2005 Acura MDX, 2004 Acura MDX, and 2003 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
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. This is to prevent pinching your hand or fingers during auto-up operation.
