U2468 – Invalid Data Received from Vehicle Control Module.

The ODBII code U2468 indicates that the vehicle’s control module has received invalid or corrupted data from another control module, leading to communication issues within the vehicle’s network.

The severity of ODBII code U2468 is generally considered moderate.

Common Causes For: U2467 refers to a communication issue related to the “Battery Energy Control Module (BECM)”.

• Faulty Vehicle Control Module (VCM)
• Poor or damaged wiring/connectors
• Corrupted software or firmware in the VCM
• Communication issues between modules
• Low battery voltage or electrical issues
• Faulty sensors sending incorrect data
• Grounding issues in the electrical system

Common misdiagnosis for U2468 Invalid Data Received from Vehicle Control Module.

• Faulty Vehicle Control Module (VCM)
• Wiring issues or shorts in the communication lines
• Faulty Engine Control Module (ECM)
• Incorrectly configured or programmed modules
• Faulty sensors related to vehicle control
• Issues with the CAN bus system
• Power supply problems to the control modules
• Corrupted software or firmware in the control modules

Common Troubleshooting Steps

The OBD-II code U2468 indicates that there is an issue with the communication between the vehicle control module (VCM) and other modules in the vehicle. This code typically points to invalid data being received from the VCM, which can be caused by various factors. Here are some common troubleshooting steps to diagnose and resolve the issue:

• Check for Other Codes: Use an OBD-II scanner to check for any additional trouble codes. Sometimes, related codes can provide more context for the issue.
• Inspect Wiring and Connectors:
• Visually inspect the wiring and connectors associated with the VCM and other modules. Look for signs of damage, corrosion, or loose connections.
• Ensure that all connectors are securely plugged in and that there are no bent pins.
• Check for Ground Issues:
• Ensure that the ground connections for the VCM and other related modules are secure and free of corrosion. Poor grounding can lead to communication issues.
• Battery Voltage Check:
• Verify that the vehicle’s battery is in good condition and that the voltage is within the normal range (typically 12.4 to 12.6 volts when the engine is off). Low voltage can cause communication problems.
• Inspect the VCM:
• If the wiring and connections are good, the issue may lie within the VCM itself. Check for any signs of physical damage or water intrusion.
• If possible, perform a software update or reset the VCM to see if that resolves the issue.
• Check for Interference:
• Look for any aftermarket devices or modifications that may interfere with the vehicle’s communication network. This includes things like aftermarket radios, alarms, or other electronic devices.
• Scan for Communication Issues:
• Use a professional-grade scan tool to check the communication between the VCM and other modules. This can help identify if the issue is isolated to a specific module.
• Perform a Network Test:
• If you have access to a network diagnostic tool, perform a network test to check for communication errors between modules.
• Clear Codes and Test Drive:
• After performing the above checks and repairs, clear the trouble codes and take the vehicle for a test drive to see if the code reappears.
• Consult Technical Service Bulletins (TSBs):
• Check for any TSBs related to the U2468 code for your specific vehicle make and model. Manufacturers may have specific recommendations or known issues. 1
• Professional Diagnosis:
• If the issue persists after performing these steps, it may be necessary to consult a professional mechanic or technician who has experience with your vehicle’s specific systems. By following these troubleshooting steps, you can systematically identify and resolve the underlying issue causing the U2468 code.
