Rear Door Window Operation

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

Refer to: Power Door Window Initialization .

Both rear door 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.

Driver Side Rear Door Window Operation

The driver door window control switch communicates to the DDM through a LIN. The DDM communicates to the RDM through a LIN.

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

Passenger Side Rear 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). The PDM communicates to the RDM through a LIN.
