2. Address Fault Codes

Using the OBD-II scanner, note down any codes that appear related to the traction control system.
Clear the codes and see if the traction control light returns. If it does, proceed with further diagnostics.

3. Inspect and Repair Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from each sensor.
Clean the sensor and the mounting area to ensure proper operation.
If damaged, replace the wheel speed sensor with a new one.
Reconnect the sensor and ensure it is securely fastened.

4. Check Brake System

Inspect brake pads and rotors for wear and replace if necessary.
Ensure brake fluid is at the correct level and quality; change if dirty.
Test the brake system for any leaks or malfunctioning components.

5. Inspect ABS Module

Locate the ABS module and check for any visible damage or leaks.
