Indicator Lights: Brake

BRAKE Light Emitting Diode (LED) is controlled by Electronic Brake Control Module (EBCM) and Body Control Module (BCM) on Class 2 serial data line. LED illuminates when one or more of the following conditions exists:

• Low brake pressure condition exists.
• Low brake fluid condition exists.
• EBCM cannot control ANTI-LOCK indicator.
• Brake pressure differential switch is closed.
• BCM sends Class 2 serial data message to instrument cluster indicating parking brake is set.
• Instrument cluster receives Class 2 serial data message from EBCM requesting BRAKE indicator on.
• As a check, LED illuminates for 3 seconds after ignition is turned on.
