Brake System Indicators: Brake
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
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.
