ABS Indicator

Range: ON/OFF
This data indicates what message is being sent from the BCM to the instrument cluster in order to control the ABS indicator illumination. When the electronic brake control module (EBCM) transmits a Class 2 serial data message to the BCM indicating there is an ABS fail condition, ON is displayed. The BCM sends a data message on the SPI data line to the instrument cluster in order to illuminate the ABS indicator.

When the BCM is sending a message to the instrument cluster not to illuminate the ABS indicator, OFF is displayed. In the event of a SPI data loss, the ABS indicator will not be commanded to illuminate (remain off) unless the ABS indicator was illuminated prior to the SPI data loss.
