Solution

1. Preparation

Gather necessary tools and parts.
Make sure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Scan for Codes

Use an OBD-II scanner to read any ABS-related trouble codes.
Make a note of any codes for further analysis.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Check for any physical damage, dirt, or debris on the sensors.
Ensure wiring connectors are secure and free from corrosion.
Clean sensors with an appropriate cleaner if contamination is present.

4. Check ABS Module and Wiring

Locate the ABS control module, typically found near the master cylinder.
Inspect the wiring harness for frays, breaks, or corrosion.
If a fault is suspected, use a multimeter to check for continuity in the wiring.

5. Verify Brake Fluid Level

Check the brake fluid reservoir; it should be at the recommended level.
If low, top off with the manufacturer-recommended brake fluid type (DOT 3 or DOT 4).

6. Clear Codes and Test Drive

After repairs, use the OBD-II scanner to clear any stored ABS codes.
Reconnect the battery and start the vehicle.
Conduct a test drive to ensure the ABS light does not reappear and braking performance is normal.
