Brake Warning System

Brake Warning System Description and Operation

Brake System Indicators

Brake

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.

Check Brake Fluid

The IPC illuminates the CHECK BRAKE FLUID indicator in the driver information center (DIC) and sends a serial data message in order to activate an audible warning when the IPC detects that the brake fluid level is below the normal operating range.
