Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, multimeter, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor area using a soft cloth.
Disconnect the electrical connector from each sensor and inspect for corrosion or damage.
Use a multimeter to test the sensor resistance according to the manufacturer’s specifications.

3. Check ABS Module

Locate the ABS module, typically found near the brake master cylinder.
Connect the OBD-II scanner to retrieve any stored error codes.
Clear any codes and conduct a test drive to see if the traction control light returns.
If the light reappears, further diagnostics on the ABS module may be required.

4. Verify Traction Control Switch Functionality

Locate the traction control switch on the dashboard.
Inspect the switch for physical damage or malfunction.
Use a multimeter to test the continuity of the switch when activated.

5. Inspect Wiring and Connectors

Follow the wiring harness from the wheel speed sensors and ABS module.
Look for any signs of fraying, corrosion, or breaks in the wiring.
Repair or replace any damaged wiring or connectors as necessary.

6. Brake Pedal Position Sensor Test

Locate the brake pedal position sensor, usually mounted on the brake pedal assembly.
Disconnect the sensor and test its output with a multimeter while engaging the brake pedal.
Replace the sensor if it fails to provide the correct readings.
