Power Window Operation - Front
Refer to: Power Door Window Initialization .
The power windows operate when the delayed accessory relay is active. The delayed accessory relay (non-serviceable) is located in the BCM. 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 driver door window control switch communicates to the DDM through a LIN. When commanded by the driver door 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 driver door window control switch must be released and activated again to move the window).
Passenger 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).
When commanded by the driver door 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 driver door window control switch must be released and activated again to move the window).
Rear Door Window Operation
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.
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).
