Brake System Indicators: Brake

WARNING: This page is about a different car, the 2009 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

The instrument panel cluster (IPC) illuminates the BRAKE indicator when any of the following occurs:

The body control module (BCM) detects that the park brake is applied and sends serial data message to illuminate indicator.
The IPC detects a low brake fluid condition.
The electronic brake control module (EBCM) detects a malfunction with the antilock brake system (ABS). The IPC receives a serial data message from the EBCM requesting illumination.
The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 5 seconds.
