Repair Instructions

Clear Codes:
- After diagnosing the problem, clear any trouble codes with the OBD-II scanner and test drive the vehicle. If the warning light returns, further investigation is necessary.
Replace Faulty Wheel Speed Sensors:

  - Lift the vehicle and remove the wheel.
  - Disconnect the wiring harness from the sensor.
  - Remove the retaining bolt and sensor from the hub.
  - Install the new sensor and reconnect the wiring harness.
  - Reinstall the wheel and lower the vehicle.
Recalibrate the Steering Angle Sensor:
- Follow the manufacturer's procedure for recalibration using the scan tool. Ensure the wheels are straight and the steering wheel is centered during calibration.
Replace or Repair the Brake Switch:
- If the brake switch is faulty:
  - Disconnect the battery to prevent shorts.
  - Remove the old brake switch by twisting or unbolting it from the mounting point.
  - Install the new switch and reconnect the battery.
Check and Replace the Traction Control Module:
- If the TCM is confirmed faulty using the diagnostic tool:
  - Disconnect the battery.
  - Locate the TCM, usually under the dashboard or near the engine compartment.
  - Remove the mounting bolts and electrical connectors.
  - Install the new TCM and reconnect all connectors.
  - Reconnect the battery and recheck for codes.
Final Test:
- After repairs, perform a test drive in various conditions (dry, wet, and slippery surfaces) to ensure the traction control system is functioning correctly.
- Monitor the dashboard for any warning lights and verify that the vehicle handles properly.

Conclusion

If the traction control system continues to malfunction after these steps, consider consulting a dealership or a qualified automotive technician for further diagnosis, as advanced diagnostics may be required.
