Instrument Cluster

OVERVIEW
The primary task of the instrument cluster is to display current vehicle status through a series of analogue gauges, indicator lamps, and a LCD (liquid crystal display) message center. In addition to this, the instrument cluster:
- Acts as a gateway between the medium speed and high speed CAN (controller area network) bus networks
- Is connected by the LIN (local interconnect network) bus to the start control unit and the steering wheel clockspring
- Controls operation of the steering column adjust feature For additional information, refer to Steering Column Description
- Acts as an interface for the passive anti-theft system. For additional information, refer to Anti-Theft - Active Description
Two analogue gauges are located in the instrument cluster; the speedometer and the tachometer. The speedometer is located on the LH (left-hand) side of the instrument cluster. The tachometer is located on the RH (right-hand) side of the instrument cluster
and displays engine speeds up to 7000 Revolutions Per Minute (RPM) for the supercharged engine, 8000 RPM for the naturally aspirated engines and 6000 RPM for diesel variants.
The message center is a LCD (liquid crystal display) located in a central position in the cluster. The message center displays system status information including fuel quantity remaining.
