Description and operation - Overview
DOOR WINDOW MECHANISMS
Operation of the window lift system is controlled by the CJB (central
junction box) in conjunction with the driver door module and the front
passenger door module. The door modules are mounted in the door of
their respective windows. Door modules are also mounted in both rear
doors, and communicate with the front door modules over the Medium
Speed (MS) CAN body bus.
The window lift system features one shot up and down operation, plus an
anti-trap feature for all door windows.
FIXED GLASS
The laminated windshield is bonded and sealed to the body aperture using
PU (polyurethane) adhesive.
The toughened rear window is also bonded and sealed to the tailgate
aperture using PU adhesive. A single heating element is printed on the inner
surface of the rear window.
