Front 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 (501-11 Glass, Frames and Mechanisms, General Procedures).

The power windows operate when the ignition is on or the accessory delay feature is active. The accessory delay feature allows the windows to function for several minutes after you switch off the ignition or until a front door is opened. Both front 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.

Driver Door Window Operation

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

Passenger Door Window Operation

The master window control switch communicates to the DDM through a LIN . The DDM communicates to the PDM through the MS-CAN . The passenger door window control switch is wired directly to the PDM .

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

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 (501-11 Glass, Frames and Mechanisms, General Procedures).

The power windows operate when the ignition is on or the accessory delay feature is active. The accessory delay feature allows the windows to function for several minutes after you switch off the ignition or until a front door is opened. Both rear door windows are equipped with obstacle detection and one-touch up and one-touch down functionality. If an obstacle is 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 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 window).

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 MS-CAN . The PDM 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 window).

Passenger Windows Lock-Out

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.

Global Open/Close (if equipped)

The RKE can be used to operate the windows when the ignition is off and the accessory delay feature is not active. Within a short time after unlocking the vehicle doors with the RKE transmitter, press and hold the unlock button on the RKE transmitter until the windows begin moving. The windows automatically open. To close the windows, press and hold the lock button on the RKE transmitter until the windows begin moving. The windows automatically close. Pressing the lock or unlock button while the windows are moving (in either direction) stops window movement.

Rear Window Defrost

When the rear window defrost button on the touchscreen or the max defrost button is pressed, the HVAC module activates the rear window defrost relay (integral to the BJB ).

The HVAC module deactivates the rear window defrost relay when one of these conditions is met:

• The rear window defrost button is pressed when the feature is active.
• Ignition state changes from ON to OFF.
• A predetermined timer completes.
• Battery voltage drops below a specified threshold (load management strategy).

Component Description

Master Window Control Switch

The master window control switch receives voltage whenever the delayed accessory relay is active. The master window control switch is grounded through the DDM . The master window control switch communicates to the DDM through a LIN .

Passenger Front Door Window Control Switch

The passenger door window control switch contains momentary contacts (one for each window switch direction). The PDM provides a return (ground) for the passenger door window control switch. When the control switch is activated, a ground signal is supplied to the PDM to operate the passenger door window regulator motor in the desired direction.

Rear Door Window Control Switch

Each of the rear door window control switches contains momentary contacts (one for each window switch direction). The driver or passenger side RDM provides a return (ground) for the rear door window control switch. When the rear door window control switch is activated, a ground signal is supplied to the driver or passenger side RDM to operate the rear door window regulator motor in the desired direction.

Door Window Regulator Motor

The door window regulator motor(s) are bi-directional. Window direction is determined by the polarity of the voltage being supplied to the motor from the associated door module. The door window regulator motor contains 2 Hall-effect sensors. The Hall-effect sensor power supply and return circuits are provided by the associated door module.

HVAC Module

The HVAC controls the rear window defrost relay. PMI is required if installing a new module.

Front Display Interface Module (FDIM)

The FDIM contains a redundant rear window defrost button on the touchscreen display. The FDIM plugs directly into the APIM , and does not communicate directly on any network.
