Possible causes

- Faulty ABS fuse or relay.
- Damaged ABS module wiring or connector.
- Faulty ABS module.
Diagnosis and repair
- Read all ABS module codes and address other faults first.
- Check battery voltage, ABS fuses and relays.
- Inspect ABS module connectors and grounds.
- Check wheel speed sensors in live data.
- Repair the cause, clear the code and road test carefully.
