Rear Power Window Operation

NOTE: If the 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 - Vehicles With: One-Touch Open and Close Front Windows .

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.

Driver Side Rear Window Operation

The driver window control switch communicates to the DDM through a private LIN. The rear door window control switch is wired directly to the DDM. When commanded by the driver window control switch or the rear window control switch, the DDM supplies power and ground to operate the driver side rear window in the desired direction. The DDM monitors fluctuations of the motor current (ripple count for DC motors) to determine the window glass position.

Passenger Side Rear Window Operation

The driver window control switch communicates to the DDM through a private LIN. The DDM communicates to the PDM through the MS-CAN. The rear door window control switch is wired directly to the PDM. When commanded by the driver window control switch or the rear window control switch, the PDM supplies power and ground to operate the passenger side rear window in the desired direction. The PDM monitors fluctuations of the motor current (ripple count for DC motors) to determine the window glass position.

Rear Passenger Windows Lock Out

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