U0585 Invalid Data Received from Vehicle Dynamics Control Module

The OBD2 code U0585 indicates that the vehicle's control module has received invalid or corrupted data from the Vehicle Dynamics Control Module, which may affect the vehicle's stability and handling systems

Definition

The OBD2 code U0585 indicates that the vehicle's control module has received invalid or corrupted data from the Vehicle Dynamics Control Module, which may affect the vehicle's stability and handling systems

Common causes

  • Faulty Vehicle Dynamics Control Module (VDCM)
  • Communication issues (wiring or connectors)
  • Corrupted software or firmware in the VDCM
  • Faulty or damaged sensors related to vehicle dynamics
  • Issues with the CAN bus system
  • Power supply problems to the VDCM
  • Grounding issues in the vehicle's electrical system

Common misdiagnoses

  • Faulty ABS module
  • Faulty traction control module
  • Wiring issues or shorts in the CAN bus
  • Faulty vehicle speed sensor
  • Malfunctioning engine control module (ECM)
  • Incorrectly calibrated or faulty steering angle sensor
  • Issues with the powertrain control module (PCM)
  • Battery or charging system problems
  • Faulty or corroded connectors in the communication network
  • Software or firmware issues in the vehicle dynamics control module

Troubleshooting steps

  1. 1. Check for Additional Codes

  2. 2. Use an OBD-II scanner to check for any other trouble codes that may be present. This can provide more context and help identify related issues

  3. 3. Inspect Wiring and Connectors

  4. 4. Visually inspect the wiring and connectors related to the Vehicle Dynamics Control Module (VDCM). Look for signs of damage, corrosion, or loose connections

  5. 5. Pay special attention to the ground connections, as poor grounding can lead to communication issues

  6. 6. Check the Vehicle Dynamics Control Module

  7. 7. Ensure that the VDCM is functioning properly. If possible, test the module with a scan tool to see if it responds correctly to commands

  8. 8. If the module is suspected to be faulty, consider replacing it or reprogramming it if necessary

  9. 9. Inspect the CAN Bus System

  10. 10. The VDCM communicates over the Controller Area Network (CAN) bus. Check for any issues with the CAN bus wiring, such as shorts, opens, or interference

  11. 11. Use a multimeter or oscilloscope to check the CAN bus signals for proper voltage levels and signal integrity

  12. 12. Check for Software Updates

  13. 13. Sometimes, software glitches can cause communication issues. Check with the manufacturer for any available software updates for the VDCM or the vehicle's ECU

  14. 14. Clear Codes and Test Drive

  15. 15. After performing any repairs or inspections, 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 Technical Service Bulletins (TSBs)

  17. 17. Look for any TSBs related to the U0585 code or the VDCM for your specific vehicle make and model. Manufacturers may have specific recommendations or known issues

  18. 18. Professional Diagnosis

  19. 19. 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 the specific vehicle. By following these steps, you can systematically identify and resolve the issue related to the U0585 code
