Driver Warning System

The 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
^ CRUISE
