Front Door Window Operation

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

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

The front power windows operate when the ignition is on and/or the interior light relay (non-serviceable) is active. Both front 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 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).
