Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, wheel chocks, jack and jack stands
Ensure the vehicle is parked on a flat surface and the ignition is off before beginning work.

2. Retrieve and Analyze Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition on without starting the engine.
Retrieve and note any DTCs related to the traction control system.
Research the codes to identify potential issues.

3. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush
Raise the vehicle and securely support it with jack stands.
Remove the wheels to access the wheel speed sensors.
Inspect each sensor for dirt or damage; clean them using a brush if necessary.
Reinstall the wheels and lower the vehicle.

4. Check ABS Module and Wiring

Tools Required: Multimeter
Locate the ABS module and inspect it visually for any signs of corrosion or damage.
Use a multimeter to test the voltage at the module and ensure proper function.
Repair or replace any damaged wiring or connectors.

5. Inspect Traction Control Switch

Remove the trim panel surrounding the traction control switch.
Disconnect the switch and test it using a multimeter to ensure it functions correctly.
Replace the switch if it is found to be faulty.

6. Brake Fluid Check

Open the hood and locate the brake fluid reservoir.
Check fluid level and quality; top off or replace fluid if contaminated or low.
Ensure the cap is securely fastened after the inspection.

7. Test Drive and Reset Light

Start the vehicle and take it for a test drive to ensure the traction control system is functioning properly.
If the light remains on, use the OBD-II scanner to clear any codes and reset the traction control light.
