Brake Warning Indicator
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
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).
