Brake Warning System

Brake Warning System Description and Operation

Brake System Indicators
BRAKE
The IPC illuminates the BRAKE indicator and sends a class 2 message in order to activate an audible warning when the following occurs:
^ 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 antilock 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.

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.
