Solution

1. Preparation

Gather tools and ensure the vehicle is safely parked on a level surface.
Disconnect the battery negative terminal to prevent electrical shorts.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any trouble codes related to the traction control system.
Clear the codes and see if they reappear after a test drive.

3. Inspect Wheel Speed Sensors

Remove the wheel covers or tires if necessary for access.
Visually inspect each wheel speed sensor for damage or dirt accumulation.
Clean the sensor connectors and ensure they are securely connected.
If damaged, replace the wheel speed sensor with a new one.

4. Check Brake Fluid and System

Inspect the brake fluid reservoir to ensure it is filled to the recommended level.
Look for any signs of leaks in the brake lines or around the ABS module.
If low, top off with manufacturer-recommended brake fluid and check for leaks.

5. Examine ABS Module

Locate the ABS module, typically near the brake master cylinder.
Check the wiring harness and connectors for corrosion or loose connections.
If necessary, perform a continuity test on the wiring using a multimeter.

6. Reconnect Battery and Test

Reconnect the battery negative terminal.
Start the vehicle and observe if the traction control light remains illuminated.
Take the vehicle for a test drive to confirm that the traction control system operates as intended.
