Brake Warning Indicator

The instrument panel cluster (IPC) illuminates the brake warning 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.
• The instrument panel cluster (IPC) detects a low brake fluid condition and the IPC will illumination the brake warning indicator.
• The IPC performs the bulb check.
• The EBCM detects an ABS-disabling malfunction which also disables electronic brake force distribution (EBD) and sends a serial data message to the IPC requesting illumination.
