Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is turned off.
  • Disconnect the battery to avoid any electrical shorts.
2. Inspect Wheel Speed Sensors
  • Remove the wheel corresponding to the affected sensor.
  • Clean the sensor and the area around it.
  • Check the sensor's connection and wiring for any signs of damage.
  • Reinstall the wheel and lower the vehicle.
3. Check ABS Module
  • Reconnect the battery.
  • Use the OBD-II scanner to clear any stored fault codes in the ABS module.
  • Test drive the vehicle to see if the traction control light returns.
4. Inspect Traction Control Switch
  • Locate the traction control switch on the dashboard.
  • Remove the switch from its housing.
  • Use a multimeter to test the switch for continuity.
  • Replace the switch if it is defective.
5. Brake Fluid Inspection
  • Check the brake fluid reservoir for proper fluid level.
  • If low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
  • Inspect for any leaks in the brake lines.
