ABS Indicator

The ABS indicator (amber) will be illuminated when the Electronic Brake Control Module (EBCM) transmits a Class 2 message to the Body Function Controller (BFC) indicating there is an ABS malfunction. The Body Function Controller (BFC) will then command the ABS indicator ON over the Serial Peripheral Interface (SPI) data line to the Instrument Cluster. In the event of a Class 2 serial data loss the ABS indicator will illuminate. In the event of an Serial Peripheral Interface (SPI) data link failure, the ABS indicator will illuminate.
