1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.
Ensure the vehicle is on a flat surface and properly supported with jack stands.

2. Scan and Clear Codes

Using an OBD-II scanner, read the ABS fault codes.
Note the codes for reference and clear them to see if they return after a test drive.

3. Inspect Wheel Speed Sensors

Remove the wheel covers if applicable and lift the vehicle using a jack.
Inspect the wheel speed sensor wiring and connectors for damage.
Clean any debris or corrosion from the sensor and its mounting area.
Reconnect any loose connectors securely.

4. Check ABS Fuses

Locate the fuse box and identify the ABS fuse.
Use a multimeter to check for continuity in the ABS fuse.
Replace the fuse if it is blown, ensuring the correct amperage is used.

5. Test the ABS Control Module

Inspect the ABS control module for any signs of corrosion or loose connections.
If necessary, reprogram or replace the ABS control module following the manufacturer's specifications.

6. Reassemble and Test Drive

Reattach all components and ensure everything is secure.
Reconnect the battery and perform a test drive to monitor ABS functionality.
Verify the ABS light is no longer illuminated after the test drive.
