Trouble Shooting: Self-Diagnosis
- ABS control unit performs 2 self-diagnostic functions. Initial diagnosis is performed from time engine starts until ABS indicator light goes off. Regular diagnosis is continuously performed from time ABS indicator light goes off on start-up until engine stops.
- When a problem is detected, ABS control unit will turn ABS indicator light on, turn fail-safe relay off and stop ABS control. If system returns to normal while driving (intermittent condition), ABS indicator light may go out when system returns to normal or may stay on until ignition is turned off.
