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.

OPERATION Front Door Windows General

Feed from the positive battery terminal (C0192) is supplied to fusible link 3 and fusible link 4 of the engine compartment fuse box (C0632) on an R wire. Fusible link 4 (C0574) provides a constant battery feed to the window lift relay (C0587) on an NW wire. Fusible link 4 (C0574) also provides a constant battery feed to the Central Control Unit (CCU) (C0592) on an NW wire. The CCU is mounted directly onto the rear of the passenger compartment fuse box.

Fusible link 3 (C0571) is connected to the ignition switch (C0028) by an N wire. When the ignition switch is turned to the 'ignition' position, current flows across the switch (C0028) to fuse 8 of the passenger compartment fuse box (C0588) on a G wire. Fuse 8 provides an ignition feed to the CCU (C0593).

Window Lift Relay

The earth path for the window lift relay coil is controlled by the CCU (C0593). When the CCU (C0593) receives an 'ignition on' feed from fuse 8 of the passenger compartment fuse box, it will energise the window lift relay. The energised window lift relay provides a feed to fuse 33 and fuse 34, which are also located in the passenger compartment fuse box.
