Brake System Indicator

The Instrument Panel Cluster (IPC) illuminates the Red brake indicator lamp 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.
