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

r to PDU User Guide
The c
o
mplexity of the electronics involved with the Instrument Cluster and the two multiplexed communication networks
which are connected to it, preclude the use of workshop genera l electrical test equipment. Therefore, reference should be
made to the PDU User Guide for detailed instructions on testing the Instrument Clus ter and associated circuits.
The PDU systematically test s and analyses all functions of the Instrument Clus ter, the various systems controlled by it and
individual sensors which are attached to each separate system.
Where a fault involving a remote sensor e. g. water temperature sensor, is indicated, before replacing the component, some
basic diagnostic methods may be necessary to confirm that connections are good and that wiring is not damaged.
Diagnostics using the PDU is via the CAN network, accessed at the diagnostic connector on the car.
Replaceable Parts
The only replaceable part s
are, General Illumination Bulbs, Direction Indicator Warning Bu
lbs and Main Beam Warning Bulb,
which are all of the conventional filament type. Other warning lamps are LEDs and are not replaceable.
