When the CCU is changed from transit mode to a valid market mode, and/or 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 tail window lift relay until the window 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 3 door models, ensure the roof is on (hard back) or lowered and secured (soft back).
3 Disconnect the battery earth lead, observing battery disconnection electrical precautions detailed in the Workshop Manual Service Repairs.
4 Allow at least 10 seconds to elapse before reconnecting the battery earth lead. The tail door glass will fully lower approximately 2 seconds after the battery is reconnected.
5 Start the engine. Ensure that all electrical loads, i.e. lights etc. are switched off. Increase the engine speed to 1500 rev/min. for 10 seconds.
6 After 10 seconds and whilst maintaining the engine speed at 1500 rev/min., carry out the following:
i) Close the tail door window fully to start the calibration procedure.
ii) Fully open the tail door window.
iii) Fully close the tail door window.
iv) If the tail door window remains closed, the calibration procedure is complete.
7 If the calibration procedure is unsuccessful, the CCU will sound a warning for approximately 0.8 second and fully lower the window. Repeat the calibration procedure from step 1.
8 Allow the engine to idle and then switch off the engine.
Tail door window calibration can fail for the following reasons:
- Window stops before minimum travel is achieved.
- Window does not achieve a stall.
- Window request removed before stall is achieved.
- Tail door opened while driving window up.
