Passenger Door Window Operation

The driver door window control switch communicates to the DDM  through a LIN  . The DDM  communicates to the PDM  through the Medium Speed Controller Area Network (MS-CAN).

When commanded by the driver door window control switch or the passenger door window control switch, the PDM  supplies power and ground to operate the passenger door window regulator motor in the desired direction. The PDM  monitors window glass position through feedback from 2 Hall-effect sensors (integral to the passenger door window regulator motor). If there is an issue with the Hall-effect sensor circuit(s), the PDM  only moves the window in 500 ms intervals (the passenger or driver door window control switch must be released and activated again to move the window).
