Brake Warning Indicator: Description and Operation

Brake Warning Indicator
The instrument panel cluster (IPC) illuminates the brake warning indicator when the following occurs:
^ The body control module (BCM) detects that the park brake is engaged. The IPC receives a class 2 message from the BCM requesting illumination.
^ The EBCM detects a low brake fluid condition and sends a class 2 message to the IPC.
^ The IPC performs the bulb check.
^ An ABS-disabling malfunction also disables dynamic rear proportioning (DRP).
