CENTRAL CONTROL UNIT (CCU)

The CCU is located on the back of the passenger compartment fusebox below the fascia. The CCU is responsible for controlling the following functions:

• Transit mode
• Anti theft alarm system
• Windscreen wipers
• Courtesy lamp delay
• Door open warning light
• Rear fog guard lights
• Lights on alarm
• Catalyst overheat
• Seat belt warning
• Handbrake warning
• Overspeed warning
• Rear screen wiper
• Tail door window
• Heated rear window

NOTE: Some of the above features controlled by the CCU are are market selectable and may not be operative or available in specific markets.

TestBook can be used to configure the CCU to enable/disable market selectable features, tailor anti theft alarm features to customer requirements and can also interrogate the CCU for stored fault codes and alarm triggers. TestBook is connected to the CCU via a diagnostic socket which is located in the passenger footwell.

The CCU is attached to the passenger compartment fusebox by five multiplugs. All inputs and outputs, to and from the CCU are transmitted through the fusebox.

The following sections describe the functions controlled by the CCU. For more detailed descriptions and operation, refer to the relevant section in the Electrical Reference Library (ERL).

TRANSIT MODE

The transit mode feature is to minimise battery usage when the vehicle is being stored to sale. When the CCU is programmed in transit mode, the following functions are disabled:

• RF receiver
• Tail door actuator
• Tail door window
• Central Door Locking (CDL)
• Interior lamps.

If the ignition is switched to position II, the CCU buzzer will sound an alarm to warn that the vehicle is in transit mode. The dealer can remove the transit mode feature and programme the CCU to the applicable market specification at the Pre Delivery Inspection (PDI) using TestBook.
