U1063 Lost Communication with Steering Angle Sensor

The OBD2 code U1063 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 U1063 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 power steering control module
  • Software issues or calibration errors
  • Faulty vehicle control module (VCM)
  • Interference from aftermarket devices or modifications

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. 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. Calibration

    Some vehicles require the steering angle sensor to be calibrated after installation or repair. Check the vehicle’s service manual for calibration procedures

  6. 6. Check Power and Ground

    Power Supply: Verify that the steering angle sensor is receiving the correct voltage. Use a multimeter to check the power supply at the sensor connector

  7. 7. Ground Connection

    Ensure that the ground connection for the sensor is intact and has a good connection

  8. 8. Inspect the CAN Bus

    Communication Lines: Since U1063 is a communication-related code, check the CAN bus wiring for any damage or shorts

  9. 9. Termination Resistors

    Ensure that the CAN bus has the proper termination resistors in place and that they are functioning correctly

  10. 10. Check for Interference

    Other Modules: Sometimes, other modules on the CAN bus can cause communication issues. Disconnect other modules one at a time to see if the problem resolves

  11. 11. Electrical Interference

    Look for sources of electrical interference that could affect communication

  12. 12. Update or Reprogram Modules

    Software Updates: Check if there are any software updates available for the vehicle’s control modules that may address communication issues

  13. 13. Reprogramming

    In some cases, reprogramming the affected module may resolve the issue

  14. 14. Replace the Steering Angle Sensor

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

  15. 15. Clear Codes and Test Drive

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

  16. 16. Consult Professional Help

    If the issue persists after all troubleshooting steps, it may be necessary to consult a professional mechanic or technician who has experience with the specific vehicle make and model. By following these steps, you should be able to identify and resolve the issue related to the U1063 code. Always refer to the vehicle’s service manual for specific procedures and specifications
