Driver Warning System

The Body Control Module (BCM) is responsible for interpreting most of the driver warnings. The remaining driver warning information is sent on to the instrument cluster in the form of a Class 2 serial data bus message. The BCM sends the following messages to the instrument cluster:
^ SECURITY
^ LOW WASH
^ Low Engine Coolant
^ Low Oil Level
^ High Beam
^ Washer Fluid Level Low
^ SERVICE VEHICLE SOON
^ Door Ajar
^ Seat Belt
^ PRNDL
^ CRUISE
