OVERVIEW

The laminated windshield is bonded and sealed to the body aperture using Polyurethane (PU) adhesive. Bonded to the inner surface of the windshield is the mounting boss for the interior mirror. Dependent on vehicle specification, the windshield may contain 2 heating elements between the windshield laminations.

The toughened rear screen is also bonded and sealed to the body aperture using PU adhesive. A single heating element is printed on the inner surface of the rear screen.

Operation of the window lift system is controlled by the CJB in conjunction with the driver door module and the front passenger door module. The door modules are mounted on the regulators of their respective front windows. Door modules are also mounted on both rear window regulators, and communicate with the front door modules over the Local Interconnect Network (LIN) bus.

The window lift system features one shot up and down operation, plus an anti-trap feature for all door windows.

If the battery is disconnected, the window lift system will require calibrating on battery re-connection. To calibrate the system the following routine must be carried out.

With the ignition on:
^ Fully close the door glass and release the switch.
^ Re-apply the switch to close the door glass and hold for approximately 2 seconds.
^ Fully open the door glass and release the switch.
^ Re-apply the switch to open the door glass and hold for approximately 2 seconds.
^ Repeat for all remaining windows.

DOOR MODULES





In addition to controlling the window lift system, the front door modules also control:
^ Door locking.
^ Door mirror adjustment and heating.
^ Door mirror lamps.

The rear door modules control window lift and door locking only.

The door modules are color coded for position on the vehicle. The driver door module and both rear door modules are black. The passenger door module is gray. The electrical wiring harness connectors are also color coded to match the door modules.

NOTE: Both rear door modules are identical.

If a front door module develops a fault, a Diagnostic Trouble Code (DTC) is stored in its memory. The DTC can be read using the Land Rover approved diagnostic system. If either of the rear door modules develop a fault, the DTC is stored in the respective front door module.
