Brake Warning Indicator
The instrument cluster turns the brake warning indicator ON when the following occurs:
* The instrument cluster performs the bulb check. The brake warning indicator illuminates for 5 s.
* The electronic brake control module (EBCM) detects a faulty pump motor, solenoid valves, an internal hardware failure or a too high or too low battery voltage and sends a serial data message to the instrument cluster requesting illumination.
* The body control module (BCM) detects that the parking brake is engaged. The instrument cluster receives a serial data message from the BCM requesting illumination.
