Brake System Warning Indicator
WARNING: This page is about a different car, the 2008 Chevrolet Malibu. 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 any of the following instances occur.
- The body control module (BCM) detects that the park brake is engaged. The BCM sends a serial data message to the IPC requesting illumination.
- The BCM detects a low brake fluid condition. The EBCM sends a serial data message to the IPC requesting illumination.
- The IPC performs the bulb check.
- The IPC detects a loss of serial data communication with the EBCM.
- The EBCM detects an ABS-disabling malfunction which also disables dynamic rear proportioning (DRP). The EBCM sends a serial data message to the IPC requesting illumination.
