Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Self-Diagnosis Function
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 light (1) as described.
- When ignition switch is turned ON, ABS warning light lights for 2 seconds to check its circuit.
- When no abnormality has been detected (the system is in good condition), ABS warning light turns OFF after 2 seconds.
- When an abnormality in the system is detected, ABS warning light lights and the area where that abnormality lies is stored in the memory of EEPROM in ABS control module.
