Brake System Indicator
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster (IPC) illuminates the brake indicator when the following occurs:
- The electronic brake control module (EBCM) detects that the park brake is engaged. The IPC receives a serial data message from the EBCM 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 EBCM receives a serial data message from the IPC requesting illumination.
- The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
