U2285 Lost Communication with the Steering Angle Sensor

The OBD2 code U2285 indicates that there is 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 U2285 indicates that there is 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 vehicle control module (VCM)
  • Software issues or outdated firmware
  • Corrosion in connectors or terminals
  • 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 Instrument Cluster
  • Issues with the CAN Bus Communication
  • Battery or Grounding Problems

Troubleshooting steps

  1. 1. Check for Other Codes

    Use an OBD-II scanner to check for any additional trouble codes. Other codes may provide more context or indicate related issues

  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 at the sensor to ensure it is within the manufacturer’s specifications

  6. 6. Check Power and Ground

    Power Supply: Verify that the steering angle sensor is receiving the correct voltage from the vehicle’s electrical system

  7. 7. Ground Connection

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

  8. 8. Inspect the CAN Bus

    Communication Lines: Since the steering angle sensor communicates over the CAN bus, check the CAN bus wiring for shorts, opens, or other issues

  9. 9. Termination Resistors

    Ensure that the CAN bus termination resistors are present and functioning correctly

  10. 10. Scan Tool Data

    Use a scan tool to monitor live data from the steering angle sensor. Look for any irregularities in the readings when turning the steering wheel

  11. 11. Check if the steering angle sensor is recognized by the vehicle’s computer

  12. 12. 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

  13. 13. Check for Software Updates

    In some cases, a software update for the vehicle’s ECU may resolve communication issues. Check with the manufacturer for any available updates

  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

  15. 15. Professional Diagnosis

    If the issue persists after performing the above steps, consider seeking help from a professional mechanic or dealership, as they may have specialized tools and knowledge to diagnose the problem further. By following these steps, you should be able to identify the cause of the U2285 code and take appropriate action to resolve the communication issue with the steering angle sensor
