U1360 U1360: "Module Communication Failure

The OBD2 code U1360 indicates a "Module Communication Failure," meaning there is a problem with communication between the vehicle's control modules, which may affect their ability to share data or function properly

Definition

The OBD2 code U1360 indicates a "Module Communication Failure," meaning there is a problem with communication between the vehicle's control modules, which may affect their ability to share data or function properly

Common causes

  • Faulty wiring or connectors
  • Failed or malfunctioning module
  • Corrupted software or firmware in the module
  • Poor ground connections
  • Intermittent electrical issues
  • Communication network issues (e.g., CAN bus problems)
  • Low battery voltage or power supply issues
  • Incompatible or aftermarket modules installed

Common misdiagnoses

  • Faulty wiring or connectors
  • Defective control module
  • Software issues or updates needed
  • Battery or power supply problems
  • Grounding issues
  • Intermittent communication issues
  • Other communication protocol failures

Troubleshooting steps

  1. 1. Check for Other Codes

    Use an OBD-II scanner to check for any other trouble codes that may be present. Sometimes, U-codes can be related to other issues that may provide more context

  2. 2. Inspect Wiring and Connectors

    Examine the wiring and connectors associated with the affected module(s). Look for signs of damage, corrosion, or loose connections. Pay special attention to ground connections, as poor grounding can lead to communication issues

  3. 3. Check Power Supply

    Ensure that the affected module is receiving the proper voltage and ground. Use a multimeter to check the power supply to the module

  4. 4. Inspect the Module

    If the wiring and power supply are good, the module itself may be faulty. Check for any visible damage or signs of water intrusion. If possible, test the module in another vehicle or replace it with a known good unit

  5. 5. Check for Interference

    Sometimes, aftermarket accessories or modifications can interfere with module communication. If any recent changes have been made to the vehicle, consider removing them to see if the issue resolves

  6. 6. Perform a Network Test

    Use a scan tool capable of performing a network test to check the communication between modules. This can help identify which module is not communicating properly

  7. 7. Reset the Modules

    Disconnect the battery for a few minutes to reset the modules. Reconnect the battery and see if the code returns

  8. 8. Update Software/Firmware

    In some cases, a software update may be required for the affected module. Check with the manufacturer or a dealership for any available updates

  9. 9. Consult Technical Service Bulletins (TSBs)

    Look for any TSBs related to the specific make and model of the vehicle. Manufacturers may have issued guidance on common issues related to module communication

  10. 10. Seek Professional Help

    If the issue persists after performing these steps, it may be necessary to consult a professional mechanic or technician who has experience with the specific vehicle and its systems. By following these steps, you can systematically diagnose and potentially resolve the U1360 code
