Power Window Operation - Front

NOTE: If the vehicle battery is disconnected, the one-touch up and one-touch down feature (and obstacle detection) is disabled prior to initialization.

Refer to: Power Door Window Initialization .

The power windows operate when the interior light relay is active. The interior light relay is active whenever the ignition is on or the ignition has been turned off within a predetermined amount of time and the front doors have not been opened. Both front windows are equipped with obstacle detection and one-touch up and one-touch down functionality. If an obstacle has been detected in the window opening as the window glass is moving upward, the window motor automatically reverses direction and moves the glass downward.

Left Hand (LH) Window Operation

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

Right Hand (RH) Window Operation

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