Brake System Indicators

The IPC illuminates the BRAKE indicator and sends a class 2 message in order to activate an audible warning when the following occurs:

1. BRAKE
   
   
   • The IPC detects that the park is applied (signal circuit is low).
   • The IPC detects a low brake fluid condition (signal circuit is low).
   • The electronic brake control module (EBCM) detects a malfunction with the anti-lock brake system. The IPC receives a class 2 message from the EBCM requesting illumination.
   • The IPC detects a loss of communications with the EBCM and the discrete back-up ABS indicator signal is open.
   • The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
2. CHECK BRAKE FLUID - 37
   
   The IPC illuminates the CHECK BRAKE FLUID -- 37 indicator in the DIC and sends a class 2 message in order to activate an audible warning when the IPC detects that the brake fluid level is below the normal operating range.
