Tail Door Window

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) is connected to fuse 14 and fuse 31 of the passenger compartment fuse box (C0587) by an NW wire. Fuse 31 (C0583) provides a constant battery feed to the tail door window lift relay (C0043) on a PN wire. Fuse 14 (C0583) provides a constant battery feed to the roof on switch (3 door vehicles only) (C0497) on a P wire.

Fusible link 4 (C0574) also provides a constant battery feed to the Central Control Unit (CCU) (C0593), via the passenger compartment fuse box (C0587) on an NW wire. The CCU (C0593) is earthed via the passenger compartment fuse box (C0587) on a B wire.

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 to fuse B of the passenger compartment fuse box (C0588) on a G wire. Fuse 8 provides an ignition feed to the CCU (C0593).

Tail Door Wiper Motor
The CCU will not operate the tail door window if the rear wiper is operational. The CCU (C0428) monitors the condition of the rear wiper by providing a feed to the 'off screen' park switch (C0388) on an OB wire. The 'off screen' park switch is open circuit at all times except when the rear wiper is in the park position. When the wiper is in the park position, current flows across the switch contacts (C0388) to earth on a B wire. The CCU will only operate the tail door window when it registers this earth path.

The CCU (C0428) also monitors the position of the rear wiper by providing a feed to the 'on screen' switch (C0388) on an NG wire. The 'on' screen switch is open circuit at all times except when the rear wiper is at the top of its travel. At this point, the switch contacts close, and an earth path is created on a B wire.

NOTE: The rear wiper will not operate if the tail door glass has not been calibrated.

Roof On Switch (3 Door Vehicles Only)
The roof on switch (C0497) is located on the RH 'D' post, and is provided a constant battery feed by fuse 14 of the passenger compartment fuse box (C0583) on a P wire. The roof on switch is closed when the hard back is fitted, or the soft back is in the fitted position. In this instance current flows across the switch (C0497) to the CCU (C0428) on a PY wire.

If the hard back is removed (or the soft back is folded down) the roof on switch becomes open circuit, and the feed to the CCU is removed. The CCU will now inhibit operation of the tail door window.

Tail Door Window Switch
The tail door window switch is located on the center console. The CCU (C0428) provides feeds to the switch (C0354) on a BR wire and a BK wire. When the switch is moved to the down position, current supplied to the switch on the BR wire flows across the closed switch contacts to earth on a B wire. When the CCU registers this earth, it powers the tail door window down.

When the switch is moved to the up position, current supplied by the CCU on the BK wire flows across the closed switch contacts to earth on a B wire. When the CCU registers this earth, it powers the tail door window up.

Up
When up operation of the tail door window is requested, the CCU (C0429) provides a feed to the window lift relay module (C0043) on an RU wire. The relay module (C0043) is now able to provide a feed to the window motor (C0612) on a UB wire. Current flows across the motor windings (C0612) and back to the relay module (C0043) on a UG wire. The relay module (C0043) is earthed on a B wire.

Down
When down operation of the tail door window is requested, the CCU (C0429) provides a feed to the window lift relay module (C0043) on an RG wire. The relay module (C0043) is now able to provide a feed to the window motor (C0612) on a UG wire. Current flows across the motor windings (C0612) and back to the relay module (C0043) on a UB wire. The relay module (C0043) is earthed on a B wire.

Tail Door Window Motor
The CCU needs to know the position of the tail door window at all times (see Description).

To do this, the CCU (C0429) provides a feed to a hall effect sensor located within the tail door window motor (C0612) on an SP wire. The sensor (C0612) is provided an earth by the CCU (C0430) on a KB wire. The hall effect sensor (C0612) provides a signal feed to the CCU (C0429) on an SR wire, informing it of the position of the tail door window.

Tail Door Open Switch
The CCU (C0428) monitors the condition of the tail door exterior handle by providing a feed to the tail door open switch (C0615) on an N wire. When the tail door handle is operated, current flows across the switch (C0615) to earth on a B wire. When the CCU registers this earth, it delays opening the tail door and lowers the tail door window approximately 17 mm.

The CCU (C0428) also monitors the condition of the tail door barrel switch (C0615) on a US wire. When the key is turned inside the barrel, current flows across the switch (C0615) to earth on a B wire. If the CCU registers a continuous earth path for approximately 2 seconds, it will lower the tail door glass.
