Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the battery to prevent electrical shorts.

2. Scan for Codes

Use an OBD-II scanner to retrieve any stored ABS fault codes.
Document the codes for further analysis.

3. Inspect Components

Check the ABS fuse:
- Locate the fuse box and identify the ABS fuse.
- Remove the fuse and check for continuity using a multimeter.
Inspect wheel speed sensors:
- Remove the wheel and brake assembly as necessary.
- Clean any dirt or debris from the sensors and their connectors.
- Check for proper alignment and secure mounting.

4. Check Wiring and Fluid

Examine the wiring harness:
- Look for frayed wires or loose connections.
- Repair or replace any damaged wiring.
Check brake fluid:
- Remove the brake fluid reservoir cap.
- Ensure the fluid is at the recommended level and is clear of contaminants.
- If low, top off with the manufacturer-recommended brake fluid.

5. Clear Codes and Test Drive

Reconnect the battery and use the OBD-II scanner to clear any ABS fault codes.
Conduct a test drive to ensure the ABS light does not re-illuminate.
