Remove the wheel on the affected axle using a socket set.
Locate the wheel speed sensor and disconnect the electrical connector.
Clean the sensor and its mounting area with brake cleaner to remove debris.
Reconnect the sensor and reinstall the wheel.

3. Replace ABS Fuse (if necessary)

Locate the fuse box under the dashboard or engine bay.
Remove the ABS fuse using a fuse puller.
Inspect the fuse for continuity; replace it with a fuse of the same amperage if blown.
Reinstall the fuse and close the fuse box.

4. Check ABS Module and Wiring

Inspect the ABS module for any visible corrosion or damage.
Ensure all connectors are secure.
Use a multimeter to test for voltage at the ABS module connectors as per the service manual specifications.
