Driver Warning Telltales

The BCM sends requests to turn the Instrument Panel Cluster (IPC) telltales ON or OFF. These requests are sent on the Class 2 serial data line. If the IPC can not communicate with the BCM via Class 2, the IPC turns the security telltale ON steady. The list of messages sent by the BCM to the IPC are as follows:
^ Over speed
^ Park brake
^ Seat belt
^ Security light
^ Turn signal reminder
^ High beam ON indicator
