Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shocks.
Allow the vehicle to cool down if it has been recently driven.

2. Scan and Clear Codes

Use the OBD-II scanner to read any stored trouble codes.
Record the codes for reference.
Clear the codes and check if the traction control light reappears after a test drive.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Locate each wheel speed sensor (usually near the wheel hub).
Clean any debris from the sensor and wiring connector.
Check the sensor's resistance with a multimeter; replace if faulty.

4. Brake System Inspection

Check brake fluid levels in the master cylinder reservoir; top off if low with the recommended fluid type.
Inspect brake pads for wear; replace if below the manufacturer's minimum thickness.
Ensure there are no leaks in the brake lines.

5. Traction Control Switch Check

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
Replace the switch if there is no continuity.

6. ABS Module Examination

Inspect the ABS module for any visible damage or corrosion.
Check electrical connections for signs of wear or loose connections.
If necessary, test the module with a diagnostic tool and replace if it fails.
