ABS Indicator

The ABS indicator (amber) will illuminate when the electronic brake control module (EBCM) transmits a class 2 message to the BCM indicating that there is an ABS malfunction. The BCM will then command the ABS indicator ON over the SPI data line to the instrument cluster. The ABS indicator will illuminate under the following conditions:
^ In the event of a class 2 serial data loss
^ In the event of an SPI data link failure
