Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors on each wheel hub.
Clean any debris or dirt from the sensors using a soft cloth.
Check the sensor wiring for any signs of wear or disconnection.

3. Check Tire Condition and Pressure

Use a tire pressure gauge to check the air pressure in each tire.
Inflate tires to the manufacturer’s recommended pressure if necessary.
Visually inspect tire tread depth; replace any tires that are worn beyond acceptable limits.

4. Inspect Traction Control Components

Reconnect the battery terminal.
Use a diagnostic tool to check for any stored error codes related to the ABS or traction control system.
Inspect the ABS module and connections for any signs of corrosion or damage.

5. Test Drive and Monitor

Conduct a test drive to see if the traction control light remains illuminated.
Monitor the vehicle’s performance under various driving conditions (accelerating, turning).
