Self Monitoring Functions

The ECU monitors the components of the system for faults. If a fault is detected, the ABS system will set a Diagnostic Trouble Code (DTC) and illuminate the amber ABS & EBD lamp, causing the ABS or EBD to be disabled. Although the ABS or EBD is inhibited, conventional brakes remain.

When the ignition switch is placed in the run position, the ECU will perform a preliminary self check on the anti-lock electrical system indicated by an illumination of the amber ABS or EBD warning lamp in the instrument cluster.
