U2113 Lost Communication with the Steering Angle Sensor

The OBD2 code U2113 indicates a loss of communication between the vehicle's control module and the steering angle sensor, which may affect the vehicle's stability control and steering functions

Definition

The OBD2 code U2113 indicates a loss of communication between the vehicle's control module and the steering angle sensor, which may affect the vehicle's stability control and steering functions

Common causes

  • Faulty steering angle sensor
  • Damaged wiring or connectors
  • Poor electrical connections
  • Malfunctioning power supply to the sensor
  • Software issues or calibration errors
  • Faulty vehicle control module (VCM)
  • Interference from other electronic components

Common misdiagnoses

  • Faulty Steering Angle Sensor
  • Wiring Issues
  • Faulty Clock Spring
  • ABS Module Failure
  • Power Steering Control Module Issues
  • Incorrectly Calibrated Steering Angle Sensor
  • Faulty Body Control Module
  • Software Issues or Updates Needed
  • Battery or Power Supply Problems
  • Faulty Instrument Cluster

Troubleshooting steps

  1. 1. Check for Other Codes

    Use an OBD-II scanner to check for any additional trouble codes. Sometimes, multiple codes can provide more context about the issue

  2. 2. Inspect Wiring and Connectors

    Visual Inspection: Check the wiring harness and connectors associated with the steering angle sensor for any signs of damage, corrosion, or loose connections

  3. 3. Connector Pins

    Ensure that the pins in the connectors are not bent, corroded, or pushed back

  4. 4. Test the Steering Angle Sensor

    Sensor Functionality: If possible, test the steering angle sensor using a multimeter or scan tool to ensure it is functioning correctly. Check for proper voltage and resistance values as specified in the vehicle’s service manual

  5. 5. Calibration

    Some vehicles require the steering angle sensor to be calibrated after installation or repair. Check if calibration is necessary

  6. 6. Check Power and Ground

    Verify that the steering angle sensor is receiving the correct voltage and that the ground connection is solid. Use a multimeter to check for power at the sensor connector

  7. 7. Inspect the CAN Bus

    Since the steering angle sensor communicates over the CAN (Controller Area Network) bus, check for issues in the CAN wiring. Look for shorts, opens, or damaged wires

  8. 8. Use a scan tool to monitor the CAN bus for any irregularities or communication issues

  9. 9. Check for Interference

    Ensure that there are no aftermarket devices or modifications that could interfere with the communication between the steering angle sensor and the vehicle’s control modules

  10. 10. Reset the Codes

    After performing inspections and repairs, clear the trouble codes using the OBD-II scanner and take the vehicle for a test drive to see if the code returns

  11. 11. Consult Technical Service Bulletins (TSBs)

    Check for any TSBs related to the steering angle sensor or communication issues for your specific vehicle make and model. Manufacturers may have issued guidance or fixes for known issues

  12. 12. Replace the Steering Angle Sensor

    If all other steps fail and the sensor is confirmed to be faulty, consider replacing the steering angle sensor

  13. 13. Seek Professional Help

    If you are unable to resolve the issue after these steps, it may be best to consult a professional mechanic or technician who has experience with your vehicle’s specific systems. By following these steps, you should be able to identify and address the cause of the U2113 code effectively
