The severity of ODBII code U1360 is moderate.

Common Causes For: U1359 Invalid Data Received from Vehicle Control Module.

• 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 misdiagnosis for U1360 U1360: “Module Communication Failure”

• 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

Common Troubleshooting Steps

The OBD-II code U1360 indicates a “Module Communication Failure,” which typically means that there is a problem with communication between the vehicle’s control modules. Here are some common troubleshooting steps to diagnose and resolve this issue:

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