Self-Diagnostic System

ABS self-diagnosis can be classified into two categories, initial diagnosis and regular diagnosis. Initial diagnosis is done right after the engine starts and until the ABS indicator goes OFF. Regular diagnosis is done right after the initial diagnosis until the ignition switch is turned OFF.

When a problem is detected by self-diagnosis, the system does the following:

• Turns the ABS indicator ON.
• Memorizes the DTC.
• Stops ABS control.
