Passenger Door

Passenger Door

To lock the passenger door, the CCU (C0430) provides a feed to the passenger door lock motor (C0441) on a K wire. The motor (C0441) is provided an earth path via the CCU (C0430) on an O wire. This enables the motor to drive the latch to the lock position.

To unlock the passenger door, the CCU (C0430) provides a feed to the passenger door lock motor (C0441) on an O wire. The motor (C0441) is provided an earth path via the CCU (C0430) on a K wire. This enables the motor to drive the latch to the unlock position.

NOTE: The driver and passenger door lock motors have the same connector numbers as they utilise the same harness.

LH Rear Door

To lock the LH rear door, the CCU (C0430) provides a feed to the LH rear door lock motor (C0442) on a K wire. The motor (C0442) is provided an earth path via the CCU (C0430) on an O wire. This enables the motor to drive the latch to the lock position.

To unlock the LH rear door, the CCU (C0430) provides a feed to the LH rear door lock motor (C0442) on an O wire. The motor (C0442) is provided an earth path via the CCU (C0430) on a K wire. This enables the motor to drive the latch to the unlock position.

RH Rear Door

To lock the RH rear door, the CCU (C0430) provides a feed to the RH rear door lock motor (C0442) on a K wire. The motor (C0442) is provided an earth path via the CCU (C0430) on an O wire. This enables the motor to drive the latch to the lock position.

To unlock the RH rear door, the CCU (C0430) provides a feed to the RH rear door lock motor (C0442) on an O wire. The motor (C0442) is provided an earth path via the CCU (C0430) on a K wire. This enables the motor to drive the latch to the unlock position.

NOTE: The LH rear and RH rear door lock motors have the same connector numbers as they utilise the same harness.

Tail Door

Operation of the tail door latch mechanism is only possible when the vehicle is stationary or travelling at speeds lower than 3 mph (5 km/h). To allow the tail door latch to operate, the CCU (C0430) provides a single voltage pulse to the tail door motor (C0617) on a PU wire. The motor (C0617) is earthed on a B wire.

The CCU receives a road speed signal from the ABS ECU. If road speed rises above 3 mph (5 km/h), the CCU will not provide a voltage pulse to the tail door motor, inhibiting operation of the tail door latch mechanism.
