Self-Diagnosis Function

WARNING: This page is about a different car, the 2006 Suzuki XL-7. However, it is still accessible from the selected car via links, so may be relevant.

ABS control module diagnoses conditions of the system component parts (whether or not there is any abnormality) all the time and indicates the results (warning of abnormality occurrence and DTC) through the ABS warning lamp as described.

When ignition switch is turned ON, ABS warning lamp lights for 2 seconds to check its warning lamp and circuit.
When no abnormality has been detected (the system is in good condition), ABS warning lamp turns OFF after 2 seconds.
When an abnormality in the system is detected, ABS warning lamp lights and the area where that abnormality lies is stored in the memory of EEPROM in ABS control module.
