Rear Power 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 .

The rear power windows operate when the delayed accessory power feature is active. Both rear 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.

LH Rear Window Operation

The master window control switch communicates to the DDM through a private LIN. The DDM communicates to the DRDM through a private LIN. When commanded by the master window control switch or the LH rear window control switch, the DRDM supplies power and ground to operate the LH rear window in the desired direction. The DRDM 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 DRDM only moves the window in 500 ms intervals (the window control switch must be released and activated again to move the window).

RH Rear 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. The PDM communicates to the PRDM through a private LIN. When commanded by the master window control switch or the RH rear window control switch, the PRDM supplies power and ground to operate the RH rear window in the desired direction. The PRDM 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 PRDM only moves the window in 500 ms intervals (the window control switch must be released and activated again to move the window).

Rear Passenger Windows Lock-Out

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

Global Open

The global open feature only activates when the ignition is off and the delayed accessory power feature is inactive. After unlocking the doors, when the unlock (or lock) button on the RKE transmitter is pressed and held, the BCM sends a request message to the DDM and PDM. When the message is received, the windows begin to open. Once the windows have begun to move, the RKE transmitter button can be released and the windows continue moving until they are fully open. If the lock or unlock button on the RKE transmitter is pressed while the windows are moving, the window operations stop.
