U0559 Invalid Data Received From Radio Transceiver

The OBD2 code U0559 indicates that the vehicle's control module has received invalid or corrupted data from the radio transceiver, which may affect communication between the radio and other systems

Definition

The OBD2 code U0559 indicates that the vehicle's control module has received invalid or corrupted data from the radio transceiver, which may affect communication between the radio and other systems

Common causes

  • Faulty radio transceiver
  • Poor electrical connections
  • Damaged wiring or connectors
  • Software or firmware issues
  • Corrupted data communication
  • Malfunctioning control module
  • Interference from other electronic devices
  • Low battery voltage or power supply issues

Common misdiagnoses

  • Faulty radio transceiver
  • Wiring issues or shorts
  • Faulty body control module (BCM)
  • Software glitches or updates needed
  • Faulty instrument cluster
  • Communication network issues (CAN bus problems)
  • Faulty antenna or signal interference
  • Incorrectly programmed or incompatible radio unit

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 and help identify related issues

  2. 2. Inspect Wiring and Connectors

    Examine the wiring and connectors associated with the radio transceiver and the vehicle's communication network. Look for signs of damage, corrosion, or loose connections

  3. 3. Reset the Code

    Clear the U0559 code using an OBD-II scanner and see if it returns after a short drive. If the code reappears, it indicates a persistent issue

  4. 4. Check the Radio Transceiver

    If the radio transceiver is accessible, inspect it for any visible damage. If possible, test the transceiver to ensure it is functioning correctly

  5. 5. Inspect the CAN Bus

    The U0559 code may be related to issues in the Controller Area Network (CAN) bus. Check for any faults in the CAN wiring, such as shorts or opens, and ensure that all modules on the bus are communicating properly

  6. 6. Test Other Modules

    If the radio transceiver is part of a larger network, check other modules that communicate with it. Ensure they are functioning correctly and not causing communication issues

  7. 7. Update Software/Firmware

    In some cases, updating the vehicle's software or firmware may resolve communication issues. Check with the manufacturer for any available updates

  8. 8. Replace the Radio Transceiver

    If all other troubleshooting steps fail and the radio transceiver is determined to be faulty, consider replacing it

  9. 9. Consult Technical Service Bulletins (TSBs)

    Check for any TSBs related to the U0559 code for your specific vehicle make and model. Manufacturers may have issued guidance on common issues and fixes

  10. 10. Seek Professional Help

    If you are unable to diagnose or resolve the issue, consider taking the vehicle to a qualified technician or dealership for further diagnosis. By following these steps, you should be able to identify the cause of the U0559 code and take appropriate action to resolve it
