U2267 Invalid Data Received from Vehicle Control Module

The OBD2 code U2267 indicates that the vehicle's control module has received invalid or corrupted data from another control module, which may affect vehicle performance or functionality

Definition

The OBD2 code U2267 indicates that the vehicle's control module has received invalid or corrupted data from another control module, which may affect vehicle performance or functionality

Common causes

  • Faulty Vehicle Control Module (VCM)
  • Poor or damaged wiring/connectors
  • Corrupted software or firmware in the VCM
  • Communication issues between modules
  • Short circuits or open circuits in the data lines
  • Faulty sensors sending incorrect data
  • Grounding issues
  • Interference from aftermarket devices or modifications

Common misdiagnoses

  • Faulty Vehicle Control Module (VCM)
  • Wiring issues or shorts in the communication lines
  • Faulty sensors related to the control module
  • Incorrectly programmed or updated software
  • Issues with the Engine Control Module (ECM)
  • Problems with the Transmission Control Module (TCM)
  • Faulty connectors or terminals
  • Battery or power supply issues
  • Grounding problems
  • Intermittent faults in the communication network

Troubleshooting steps

  1. 1. Check for Additional Codes

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

  2. 2. Inspect Wiring and Connectors

  3. 3. Visually inspect the wiring and connectors associated with the affected control module. Look for signs of damage, corrosion, or loose connections

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

  5. 5. Check for Short Circuits

    Use a multimeter to check for short circuits in the wiring harness. Ensure that there are no unintended connections between wires that could cause data corruption

  6. 6. Test the Control Module

  7. 7. If possible, test the affected control module to ensure it is functioning correctly. This may involve using specialized diagnostic tools or swapping the module with a known good one

  8. 8. Check for any software updates or reprogramming that may be required for the control module

  9. 9. Inspect the CAN Bus

  10. 10. The U2267 code often relates to issues with the Controller Area Network (CAN) bus. Use a scan tool to monitor the CAN bus for any irregularities in communication

  11. 11. Check for proper termination resistors at the ends of the CAN bus wiring

  12. 12. Clear Codes and Test Drive

    After performing any repairs or adjustments, 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 Battery Voltage

    Ensure that the vehicle's battery is in good condition and that the voltage is within the normal range. Low voltage can cause communication issues between modules

  14. 14. Consult Technical Service Bulletins (TSBs)

    Check for any TSBs related to the specific make and model of the vehicle. Manufacturers may have issued guidance on common issues related to the U2267 code

  15. 15. Seek Professional Help

    If the issue persists after performing the above steps, it may be necessary to consult a professional mechanic or technician who has experience with the specific vehicle and its control systems. By following these troubleshooting steps, you can systematically identify and resolve the underlying cause of the U2267 code
