Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools, and a jack with jack stands.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Address Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any error codes. Look for codes related to the ABS or traction control systems.
Clear the error codes and take the vehicle for a test drive to see if the light returns.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure with jack stands.
Locate each wheel speed sensor; they are typically mounted near the brake rotor.
Disconnect the connectors and inspect for corrosion or damage.
Use a multimeter to test the sensor's resistance. Replace if out of specification.

4. Check Brake System

Inspect the brake fluid reservoir for proper fluid level; refill if necessary.
Check for any leaks in the brake lines or around the ABS module.
If brake issues are found, repair as needed.

5. Verify Tire Condition

Inspect all tires for proper inflation according to the manufacturer's specifications.
Look for uneven wear or damage. Replace any compromised tires.

6. Reassemble and Test

Reconnect all components and lower the vehicle.
Take the vehicle for a test drive to verify that the traction control light does not illuminate again and that the system functions correctly.
