Door Glass

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The door glass operates with the ignition in either accessory or on mode and, after the ignition is switched off, for 5 minutes or until a door is opened.

When a window open or close selection is made on a door switchpack, the related door module supplies power to the window motor to drive it in the appropriate direction. In the inch mode, the motor stops when the switch is released or the window reaches the end of its travel. In the one-shot mode, the motor stops if the switch is operated again (either up or down) or the window reaches the end of its travel

One-shot up operation causes a door window to fully close unless an object is detected (anti-trap). If the anti-trap algorithm detects an object, the glass will drop fully open or to 200 mm below the obstruction.

When the passenger door switchpacks are used, they produces an open or close request by completing a hard wired circuit with the PDM.

When the driver door switchpack is used, it outputs a request message to the DDM on the LIN bus. If the message is for one of the passenger doors, the DDM relays the message to the relevant door module on the MS CAN body bus.

If one of the passenger doors glass has opposing up and down requests from one of the passenger door switchpacks and the driver door switchpack, operation of the door glass will cease until one of the switches is released
