Self-Diagnosis

Self-diagnosis
The ABS control unit starts self-diagnostic functions after the ignition is switched ON. The ABS control unit detects failure for each circuit and component by comparing condition of the system with limited condition set inside the ABS control unit, ABS control unit stores the failure code and then outputs the four-digits of malfunction code to the diagnostic scan tool (Hi-scan pro) when the ABS terminal of the diagnostic connector is connected.
