Circuit/System Description

The Instrument Cluster contains a Driver Information Center which displays vehicle information such as the engine coolant temperature, fuel level, vehicle speed, and other information based on the information received from various modules on the vehicle's serial data bus. The Driver Information Center illuminates a combination of indicators and messages to display the status of various vehicle systems.

The engine malfunction indicator lamp is provided ignition voltage to one side by the Instrument Cluster. To illuminate the engine malfunction indicator lamp, the Engine Control Module provides ground directly to the other side of the lamp.
