Brake Indicator

Range: ON/OFF
This data indicates what message is being sent from the BCM to the instrument cluster in order to control the brake indicator illumination. On is displayed under one of the following conditions:
^ When the park brake is engaged
^ When the EBCM sends a class 2 serial data message to the BCM indicating there is a brake fail condition

The BCM sends a SPI serial data message to the instrument cluster commanding the brake indicator to be illuminated when the parking brake is not engaged. When the EBCM is not sending a class 2 serial data message indicating a brake fail condition, OFF is displayed.

In the event of the EBCM commanding the brake indicator to illuminate, the cruise function will be cancelled. In the event of class 2 serial data loss, the brake indicator will illuminate. In the event of a SPI data line failure, the brake indicator will not illuminate unless the brake indicator was illuminated prior to the SPI data line failure.
