BRAKE Indicator

The BRAKE warning indicator (red) will illuminate under the following conditions:
^ When the ignition switch is in the RUN position
^ When the park brake is engaged

The BRAKE indicator will illuminate when the EBCM transmits a class 2 message to the BCM indicating that there has been a brake fail condition. The BCM will then command the BRAKE indicator ON over the SPI data line to the instrument cluster. In the event of the EBCM commanding the BRAKE indicator to illuminate, the cruise function will be canceled. In the event of a class 2 serial data loss the BRAKE indicator will illuminate. In the event of an SPI data link failure, the BRAKE indicator will not illuminate unless the indicator was illuminated prior to the SPI data link failure.
