Power Windows: 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 Body Control Unit (BCU).
