ABS Indicator

The ABS inop indicator is controlled by either of the following components:
^ The Electronic Brake Control Module (EBCM)
^ The instrument cluster

The EBCM sends a Class 2 message through circuit 1036 to the instrument cluster to turn on the ABS mop indicator when a problem with the ABS system has been detected. The ABS system may be disabled, but base brake performance will remain.

The instrument cluster turns on the ABS Inop indicator under the following conditions:
^ Class 2 communication has been lost between the instrument cluster and the EBCM.
^ The 3 second bulb test is occurring.
