### Brake System Indicator

The IPC illuminates the brake 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. If the vehicle is shifted out of park with the park brake engaged, the BCM activates an audible warning.

• | The IPC detects a low brake fluid condition (signal circuit is low).

• | The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
