Rear Door Window Operation

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 .

Both rear door windows are equipped with obstacle detection and one-touch up and one-touch down functionality. If an obstacle has been detected as the window glass is moving upward, the window motor automatically reverses direction and moves the glass downward.

When the lock-out switch (part of the master window control switch) is in the LOCK position, the rear door passenger power windows can only be operated from the master window control switch.

Driver Side Rear Door Window Operation

The master window control switch communicates to the DDM through a LIN. The DDM communicates to the RDM through a LIN. The rear door window control switch is wired directly to the RDM.

When commanded by the master 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 glass).

Passenger Side Rear Door Window Operation

The master 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 passenger RDM through a LIN. The rear door window control switch is wired directly to the RDM.
