Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shock.

2. Scan and Clear Codes

Use an OBD-II scanner to read error codes.
Note any codes and clear them to see if the ABS light returns after a test drive.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor if necessary and clean them with brake cleaner.
Inspect wiring for any damage or corrosion.

4. Check Brake Fluid

Open the master cylinder reservoir.
Inspect brake fluid for contamination or low levels.
Top off with the recommended brake fluid type if low.

5. Inspect Fuses

Locate the fuse box and identify the ABS fuses.
Remove each fuse and check for continuity using a multimeter.
Replace any blown fuses with the same amperage rating.

6. Reassemble and Test

Reconnect any components that were removed.
Reconnect the battery.
Conduct a test drive to observe if the ABS light returns.
