Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to prevent any electrical short circuits.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Power on the ignition (do not start the engine).
Retrieve and note any stored error codes.
Clear the codes to see if the traction control light reappears.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris from the sensor area using a clean cloth.
If damaged, replace the wheel speed sensors with new components.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; it should be between the minimum and maximum marks.
If low, top off with the recommended brake fluid type (usually DOT 4).

5. Inspect ABS Module

Locate the ABS control module, typically found near the brake master cylinder.
Visually inspect for damaged wiring or corrosion.
If any issues are found, repair or replace the affected components.

6. Test Traction Control Function

Reconnect the battery.
Start the vehicle and conduct a test drive to check if the traction control light remains off and the system functions properly.
