Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Scan and Clear Codes
  • Use an OBD-II scanner to read and document any error codes.
  • Clear the codes and check if the traction control light reappears after a short test drive.
3. Inspect Wheel Speed Sensors
  • Remove the wheel associated with the suspect sensor.
  • Locate the wheel speed sensor and check for physical damage or dirt.
  • Clean the sensor and its connector using electrical cleaner.
  • Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.
4. Check ABS Control Module
  • Locate the ABS control module, typically found near the brake master cylinder.
  • Inspect wiring and connectors for damage or corrosion.
  • If necessary, replace the ABS control module following the manufacturer's procedures.
5. Brake Fluid Check
  • Remove the brake fluid reservoir cap and check the fluid level.
  • If low, top off with the recommended brake fluid type.
  • Inspect for leaks in the brake lines or around the ABS module.
6. Test Traction Control Switch
  • Locate the traction control switch on the dashboard.
  • Using a multimeter, test the switch for continuity when engaged.
  • Replace the switch if it does not have a proper connection.
