U2268 – Invalid Data Received from Vehicle Control Module.

The ODBII code U2268 indicates that the vehicle’s control module has received invalid or corrupted data from another control module, which may affect vehicle performance or functionality.

The severity of ODBII code U2268 is generally considered moderate.

Common Causes For: U2267 Invalid Data Received from Vehicle Control Module.

• 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 misdiagnosis for U2268 Invalid Data Received from Vehicle Control Module.

• Faulty Vehicle Control Module (VCM)
• Wiring issues or short circuits
• Faulty sensors (e.g., wheel speed sensors)
• Communication issues with other modules
• Battery or power supply problems
• Corrupted software or firmware in the control module
• Faulty connectors or terminals
• Issues with the transmission control module (TCM)

Common Troubleshooting Steps

The OBD-II code U2268 indicates that there is an issue with the communication between the vehicle’s control modules, specifically that invalid data has been received from the vehicle control module (VCM). 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 additional trouble codes. Sometimes, multiple codes can provide more context about the issue.
• Inspect Wiring and Connectors:
• Check the wiring and connectors related to the VCM and other control modules for any signs of damage, corrosion, or loose connections.
• Pay special attention to the ground connections, as poor grounding can lead to communication issues.
• Verify Power Supply:
• Ensure that the VCM and other related modules are receiving the correct voltage and ground. Use a multimeter to check the power supply to the module.
• Check for Short Circuits:
• Inspect the wiring harness for any short circuits or open circuits that could affect communication between modules.
• Inspect the Control Module:
• If the wiring and connections are intact, the issue may lie within the control module itself. Check for any signs of physical damage or water intrusion.
• Update Software/Firmware:
• Check if there are any software or firmware updates available for the vehicle’s control modules. Sometimes, updating the software can resolve communication issues.
• Perform a Hard Reset:
• Disconnect the vehicle’s battery for a few minutes to reset the control modules. Reconnect the battery and see if the code reappears.
• Check for Interference:
• Ensure that there are no aftermarket devices or modifications that could interfere with the communication between control modules.
• Scan Tool Communication:
• Use a professional-grade scan tool to communicate with the VCM and other modules. This can help identify if the issue is with the scan tool or the vehicle’s communication network.
• Consult Technical Service Bulletins (TSBs):
• Look for any TSBs related to the U2268 code for your specific vehicle make and model. Manufacturers may have specific recommendations or known issues. 1
• Seek Professional Help:
• If the issue persists after performing the above steps, it may be necessary to consult a professional mechanic or technician who specializes in automotive electronics. By following these troubleshooting steps, you can systematically identify and resolve the issue related to the U2268 code.
