The In
strument Cluster is the primary electronic control module for the speedomete
r, tachometer, coolant temperature, fuel
level, driver information (Message Centre) and warning lamps.
The Instrument Cluster also:
- provides input / output informatio n signals for use by other modules.
- acts as a protocol converter (software language translator - the languages used on each network are very similar, but
neither can be directly interp reted by the opposite system) for communication between all modules on both the CAN and
SCP multiplexed networks. The Instrument Cluster is the only module on the vehicle which communicates between the two
networks.
Instrument Cluster Gauges

*Not used on all markets. Refer to the Drivers Handbook.
Although the gauges look like conventional analogue gauges, each pointer is driven by a stepper motor to provide more

Horn - Horn
Description and Operation
The horns, located behind the radiator gril le, each side of the radiator, are controlled by the Body Processor Module (BPM),
as described below.
The switch, located on the steering wheel pad, is operated, it signals the BPM to sound the horn. The BPM responds by
providing an earth from the horn-output to the horn relay coil. The relay contacts are subsequently closed and the horns
sound.
The horn operating relay, R6 is located in the engine compartm ent fusebox at the left hand side of the engine compartment.

Diagnosis and Testing
Tests Using the Portable Diagnostic Unit
Refer to PDU User Guide
The complexity of the electronics involved with the various Electronic Control Modules and the multiplexed communication
networks, preclude the use of workshop general electrical test equipment. Therefore, reference should be made to the PDU
User Guide for detailed instructions on test ing the horn circuit.
The PDU systematically tests an d analyses all functions of the horn, the horn relay, the bo dy processor module and the
operating switch.
Where a fault involving the horn, relay or switch is indicate d by the PDU, before replacing the component, some basic
diagnostic methods may be necessary to confirm that co nnections are good and that wiring is not damaged.

Clock - Clock
Description and Operation
The analogue clock is mounted in the center of fascia vent assembly and can only be removed after withdrawal of the fascia
vent assembly.
The clock is protected by a 5A fuse in lo cation F6 of the LH heelboard fusebox and illumination is controlled by the dimmer
module in the same manner as the other instruments.
The time displayed can be advanced using the positive button and retarded using the minus button.
