Definition

The OBD2 code U0435 indicates that the vehicle's control module has received invalid or corrupted data from the rear power steering control module, which may affect steering performance or functionality

Common causes

  • Faulty power steering control module
  • Wiring issues (shorts, opens, or corrosion)
  • Poor connections or loose connectors
  • Faulty power steering motor
  • Software or firmware issues in the control module
  • Malfunctioning vehicle communication network (CAN bus)
  • Low power steering fluid levels
  • Electrical interference or noise in the system

Common misdiagnoses

  • Faulty Power Steering Control Module
  • Wiring issues or short circuits
  • Faulty steering angle sensor
  • Incorrectly calibrated steering system
  • Faulty vehicle speed sensor
  • Issues with the electronic control unit (ECU)
  • Problems with the CAN bus communication
  • Low power steering fluid levels
  • Faulty connectors or terminals
  • Malfunctioning ABS module

Troubleshooting steps

  1. 1. Check for Additional Codes

  2. 2. Use an OBD-II scanner to check for any other related trouble codes. This can provide more context and help identify if there are other issues affecting the power steering system

  3. 3. Inspect Wiring and Connectors

  4. 4. Visually inspect the wiring and connectors related to the power steering control module. Look for signs of damage, corrosion, loose connections, or frayed wires that could cause communication issues

  5. 5. Check Power and Ground

  6. 6. Ensure that the power steering control module is receiving the correct voltage and ground. Use a multimeter to check for proper voltage at the module's power and ground pins

  7. 7. Inspect the Power Steering Control Module

  8. 8. If the wiring and connections are intact, the power steering control module itself may be faulty. Check for any signs of physical damage or water intrusion

  9. 9. Test the Power Steering System

  10. 10. Verify that the power steering system is functioning correctly. Check the fluid level, condition, and any potential leaks. If the system is not working properly, it may affect the module's performance

  11. 11. Check for Software Updates

  12. 12. Some vehicles may require software updates for the power steering control module. Check with the manufacturer or a dealership to see if there are any updates available

  13. 13. Clear Codes and Test Drive

  14. 14. After performing the above checks and repairs, clear the trouble codes using the OBD-II scanner. Take the vehicle for a test drive to see if the code reappears

  15. 15. Consult Technical Service Bulletins (TSBs)

  16. 16. Look for any TSBs related to the power steering system for your specific vehicle make and model. Manufacturers may have issued guidance on common issues and fixes

  17. 17. Professional Diagnosis

  18. 18. If the issue persists after performing the above steps, consider seeking help from a professional mechanic or dealership. They may have specialized diagnostic tools and experience with your vehicle's specific systems. By following these steps, you can systematically identify and address the underlying cause of the U0435 code
