1. Raise the vehicle and remove the wheel on the affected side.
2. Locate the wheel speed sensor and disconnect the electrical connector.
3. Visually inspect the sensor for damage or dirt; clean if necessary.
4. Use a multimeter to check the sensor resistance (specification varies by model).
Tools Required: Jack, jack stands, socket set, multimeter.

3. Check ABS Fuse and Relay

Sub-steps:
1. Locate the fuse box and identify the ABS fuse using the diagram on the cover.
2. Remove the ABS fuse and check for continuity with a multimeter.
3. Inspect the ABS relay for proper operation; replace if faulty.
