Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any error codes.
Clear the codes and see if the traction control light returns after a test drive.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any debris or dirt from the sensor area.
Check the wiring harness for frays or loose connections.
If damaged, replace the wheel speed sensor.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the brake fluid level; it should be within the recommended range.
If low, add the appropriate brake fluid (DOT 3 or DOT 4) as specified in the owner's manual.

5. Inspect ABS Module and Wiring

Locate the ABS module, usually found near the master cylinder.
Inspect the module for any visible signs of corrosion or connector issues.
If corrosion is present, clean the connectors with electrical contact cleaner.

6. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Press the switch to see if the light changes or if the system responds.
If the switch is unresponsive, replace it.
