The IPC illuminates the BRAKE indicator when any of the following occur:
- The IPC detects that the park brake is engaged. If the vehicle travels 3-15.2 meters (10-50 feet) with the park brake engaged, the IPC sends a class 2 message to the radio in order to activate an audible warning.
- The IPC detects a low brake fluid condition. The IPC sends a class 2 message to the radio in order to activate an audible warning.
- The electronic brake control module (EBCM) detects a failure in the braking system. The IPC receives a class 2 message from the EBCM requesting illumination. The IPC sends a class 2 message to the radio in order to activate an audible warning.
- The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 5 seconds.
- The IPC detects a loss of class 2 communications with the EBCM and the discrete back-up ABS indicator signal circuit is high.
