How to Fix Error Code C1241

  1. Scan for Additional Codes

    Ensure the vehicle is parked on level ground with the parking brake engaged before connecting diagnostic equipment.
  2. Check Steering Angle Sensor Wiring

    Disconnect the negative battery terminal before inspecting wiring to prevent accidental airbag deployment.
  3. Test Sensor Voltage

  4. Perform Steering Angle Sensor Calibration

    Vehicle must be on a level surface with wheels pointing straight ahead during calibration.
  5. Replace Faulty Components

    Always use OEM or OEM-equivalent parts to ensure proper system operation and safety.
  6. Clear Codes and Test Drive

    Drive cautiously during initial test drive as safety systems may not be fully operational until calibration is complete.
