Tail Door Window Calibration

Tail Door Window Calibration

When the CCU is changed from transit mode to a valid market mode, and after the vehicle battery has been disconnected, the tail door window must be calibrated to provide the CCU with a window position datum. When the CCU mode is changed to a valid market, or the battery reconnected, the CCU automatically begins the calibration process by energising the down contacts in the window lift relay module until the window lift motor stalls, to ensure the window is fully down. The calibration procedure is completed as follows:

1. Ensure the tail door is closed, the vehicle unlocked and the alarm disarmed. 2. On three door models, ensure the roof is on (hard back) or lowered and secured (soft back). 3. With the ignition on, use the console switch or the vehicle key in the tail door lock to raise the window until the motor stalls with the window fully closed. 4. Switch off the ignition.

NOTE: If the calibration procedure is unsuccessful, the CCU will sound a warning for approximately 0.8 seconds and fully lower the window.
