U2585 Lost Communication with the Steering Angle Sensor

The OBD2 code U2585 indicates a loss of communication with the steering angle sensor, which may affect the vehicle's stability control and steering systems

Definition

The OBD2 code U2585 indicates a loss of communication with the steering angle sensor, which may affect the vehicle's stability control and steering systems

Common causes

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

Common misdiagnoses

  • Faulty steering angle sensor
  • Wiring issues or damaged connectors
  • Faulty steering column module
  • Malfunctioning electronic stability control (ESC) system
  • Issues with the vehicle's body control module (BCM)
  • Problems with the power steering system
  • Faulty ABS module
  • Software or calibration issues in the vehicle's control modules

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 or corroded

  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 the CAN Bus Communication

    Network Integrity: Since the steering angle sensor communicates over the CAN bus, check for any issues with the CAN network. Look for short circuits, open circuits, or other communication faults

  7. 7. Scan Tool

    Use a professional scan tool to monitor the CAN bus data and see if the steering angle sensor is transmitting data

  8. 8. Inspect the Power and Ground Supply

    Power Supply: Verify that the steering angle sensor is receiving the correct voltage. Check the vehicle’s wiring diagrams for the correct voltage specifications

  9. 9. Ground Connection

    Ensure that the ground connection for the sensor is solid and free of corrosion

  10. 10. Check for Software Updates

    ECU Updates: Sometimes, the issue can be resolved with a software update to the vehicle’s ECU. Check with the manufacturer for any available updates

  11. 11. Test the Steering Column and Related Components

    Steering Column Issues: Inspect the steering column for any mechanical issues that could affect the sensor’s operation

  12. 12. Other Sensors

    Check other related sensors (like the yaw rate sensor) that may also affect the steering angle sensor’s performance

  13. 13. Clear Codes and Test Drive

    After performing the above checks 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

  14. 14. Consult a Professional

    If the issue persists after performing these steps, it may be necessary to consult a professional mechanic or technician who has experience with your specific vehicle make and model.Conclusion By following these troubleshooting steps, you can systematically identify and resolve the issue related to the U2585 code. Always refer to the vehicle’s service manual for specific details and specifications related to the steering angle sensor and its circuitry
