Driver Door Window Operation

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