U2696 – Invalid Data Received from Vehicle Dynamics Control Module.

The ODBII code U2696 indicates that the vehicle’s control module has received invalid or corrupted data from the Vehicle Dynamics Control Module, which may affect the vehicle’s stability and handling systems.

The severity of ODBII code U2696 is generally considered moderate.

Common Causes For: U2695 Invalid Data Received from Vehicle Dynamics Control Module.

• Faulty Vehicle Dynamics Control Module (VDCM)
• Communication issues between modules
• Damaged wiring or connectors
• Corrupted software or firmware in the VDCM
• Faulty sensors related to vehicle dynamics
• Low battery voltage or electrical issues
• Interference from aftermarket modifications or devices

Common misdiagnosis for U2696 Invalid Data Received from Vehicle Dynamics Control Module.

• Faulty ABS module
• Defective wheel speed sensors
• Malfunctioning traction control system
• Issues with the powertrain control module (PCM)
• Wiring or connector problems
• Faulty vehicle dynamics control module
• Incorrect tire sizes or pressures
• Software or calibration issues in the control modules

Common Troubleshooting Steps

When dealing with the OBD-II code U2696, which indicates “Invalid Data Received from Vehicle Dynamics Control Module,” it’s important to follow a systematic approach to troubleshoot the issue. Here are some common troubleshooting steps:

• 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.
• Inspect Wiring and Connectors:
• Visually inspect the wiring and connectors associated with the Vehicle Dynamics Control Module (VDCM). Look for signs of damage, corrosion, or loose connections.
• Pay special attention to the ground connections, as poor grounding can lead to communication issues.
• Check the Vehicle Dynamics Control Module:
• Ensure that the VDCM is functioning properly. If possible, test the module with a known good unit or perform a bench test if applicable.
• Check for any software updates or recalls related to the VDCM.
• Inspect Related Modules:
• Since the VDCM communicates with other modules in the vehicle, check for issues in those modules as well. This includes modules like the ABS, traction control, and stability control systems.
• Scan for Communication Issues:
• Use a scan tool to check the communication lines (CAN bus) between the VDCM and other modules. Look for any communication errors or interruptions.
• If you have access to a multimeter or oscilloscope, you can test the signal integrity on the communication lines.
• Check Power and Ground:
• Verify that the VDCM is receiving the correct power supply and ground. Use a multimeter to check voltage levels at the module’s power and ground pins.
• Clear Codes and Test Drive:
• After performing any repairs or adjustments, clear the trouble codes and take the vehicle for a test drive to see if the code returns.
• Consult Technical Service Bulletins (TSBs):
• Look for any TSBs related to the U2696 code or the VDCM for your specific vehicle make and model. Manufacturers may have specific recommendations or known issues.
• Professional Diagnosis:
• If the issue persists after performing the above steps, consider seeking help from a professional mechanic or dealership. They may have access to specialized diagnostic tools and resources. By following these steps, you can systematically identify and resolve the underlying issue causing the U2696 code.
