Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical shorts.

2. Scan and Clear Codes

Use the OBD-II scanner to read any trouble codes related to the traction control system.
If codes are present, note them down for further diagnosis.
Clear the trouble codes and see if the traction control light returns after a test drive.

3. Inspect and Replace Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from each sensor.
Remove the sensor using a socket set (if applicable) and inspect for damage.
If damaged, replace with new sensors, ensuring proper torque on mounting bolts.
Reconnect electrical connectors.

4. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Check the fluid level; if low, fill with the manufacturer-recommended brake fluid.
Inspect hoses and connections for any signs of leaks or wear.
Reconnect the battery.

5. Test the Traction Control System

Start the vehicle and take it for a short test drive.
Observe if the traction control light illuminates again.
Test the system by pressing the traction control switch to ensure it functions correctly.
