Description

General
Electric windows are installed in all four doors. The front windows are controlled by their respective door modules integrated into the window switch packs. The rear windows are controlled by the Body Control Unit (BCU). The BCU and the door modules communicate with each other on the P bus.

Window operating features are market dependent and include one-shot opening and closing convenience opening and closing, and anti-trap. Market options for window operation are set centrally in the BCU.

Window Switches
Individual window switches are installed in each of the three passenger doors. Window switches for all of the windows, and a child lock switch to isolate the rear windows, are installed in the driver's door.

All of the window switches have two switching positions in each direction. The first switching position operates the window in the inching mode where the window moves until the switch is released or until it reaches the fully open or closed position. The second switching position operates the window in the one-shot mode.

Anti-trap Sensors
An anti-trap sensor is installed along the top of each window aperture, just outside the travel path of the window glass. Each anti-trap sensor consists of a rubber covered contact strip connected to ground and to a power supply from the door module (front windows) or BCU (rear windows). When the anti-trap sensor is pressed the resistance across the contact strip is reduced. If a window is being closed and the door module/BCU detects a drop in resistance across the associated anti-trap sensor it immediately (in less than 20 milliseconds) reverses the window

Window Regulators
Cable operated window regulators powered by an electric motor are installed in each of the doors.
