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).
