Clear the codes and check if the traction control light returns after a test drive.

3. Inspect Wheel Speed Sensors

Remove the wheel for easier access if necessary.
Locate the wheel speed sensor on each wheel hub.
Clean the sensor and its connector; replace if damaged.
Reinstall the wheel and torque to manufacturer specifications.

4. Check Brake Fluid and System

Inspect the brake fluid reservoir for proper fluid level; fill as needed with the recommended brake fluid.
Inspect brake lines for leaks or damage and replace any faulty components.

5. Inspect ABS Module Wiring

Visually inspect the wiring harness connected to the ABS module for signs of wear or corrosion.
Repair or replace damaged wires, ensuring all connections are secure.
