Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to reset the system and ensure safety.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve any diagnostic trouble codes (DTCs).
Note the codes and clear them if necessary to see if they return after a test drive.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel.
Clean any dirt or debris from the sensors and their connectors.
Use a multimeter to check for continuity in the sensor wiring and replace any faulty sensors.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid is at the recommended level; top off with the correct type of fluid if necessary.
Inspect for any leaks in the brake system.

5. Test ABS Module

Inspect the ABS module for any visible signs of damage or corrosion.
Use a scan tool to check ABS function and perform an ABS self-test, if available.

6. Verify Tire Condition

Check each tire for uneven wear, proper inflation, and tread depth.
Replace any tires that are worn unevenly or below the minimum tread depth.

7. Reconnect Battery

Reconnect the negative battery terminal after completing repairs.
Start the vehicle and observe if the traction control light remains off.
