Possible causes
- Wheel-speed sensor faults
- Damaged wiring, pigtails or connectors
- Power or ground problems
Practical tips
- Check the ABS lamp during each pre-trip
- Inspect the pigtail for cuts and corrosion

What to expect.

On-site repair depends on the fault, parts, vehicle condition, safety and service feasibility.
