U2917 Lost Communication with the Steering Angle Sensor

The OBD2 code U2917 indicates a loss of communication with the steering angle sensor, which may affect the vehicle's stability control and steering functions

Definition

The OBD2 code U2917 indicates a loss of communication with 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 vehicle control module (VCM)
  • Software issues or outdated firmware
  • Interference from other electronic components
  • Low battery voltage or power supply issues

Common misdiagnoses

  • Faulty Steering Angle Sensor
  • Wiring Issues or Short Circuits
  • Faulty Body Control Module (BCM)
  • Faulty Electronic Power Steering (EPS) Module
  • Incorrectly Calibrated Steering Angle Sensor
  • Faulty ABS Module
  • Issues with the CAN Bus Communication
  • Battery or Power Supply Problems

Troubleshooting steps

  1. 1. Check for Other Codes

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

  5. 5. Resistance and Voltage

    Measure the resistance and voltage output of the sensor according to the manufacturer’s specifications

  6. 6. Check Power and Ground

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

  7. 7. Ensure that the ground connection is solid and free of corrosion

  8. 8. Inspect the CAN Bus

    Since the steering angle sensor communicates over the CAN bus, check for any issues with the CAN network

  9. 9. Look for any damaged wiring or poor connections in the CAN bus system

  10. 10. Use a scan tool to monitor the CAN bus for any communication issues

  11. 11. Check for Software Updates

    Sometimes, manufacturers release software updates that can resolve communication issues. Check if there are any updates available for your vehicle’s ECU

  12. 12. Clear Codes and Test Drive

    After performing the above checks and repairs, clear the trouble codes using the OBD-II scanner

  13. 13. Take the vehicle for a test drive to see if the code reappears

  14. 14. Consult Technical Service Bulletins (TSBs)

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

  15. 15. Replace the Steering Angle Sensor

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

  16. 16. Professional Diagnosis

    If you are unable to resolve the issue, it may be best to consult a professional mechanic or dealership for further diagnosis.Conclusion By following these steps, you should be able to identify the cause of the U2917 code and take appropriate action to resolve the communication issue with the steering angle sensor. Always refer to the vehicle’s service manual for specific procedures and specifications
