Instrument Panel, Gauges and Warning Indicators: Description and Operation

Instrument Cluster

Locations:

The Instrument Cluster is the primary electronic control module for the speedometer, tachometer, coolant temperature, fuel level, driver information (Message Center) and warning lamps.

The Instrument Cluster also:
- provides input / output information 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 interpreted 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.

Although the gauges look like conventional analogue gauges, each pointer is driven by a stepper motor to provide more accurate readings
