U2995 – Invalid Data Received from Vehicle Dynamics Control Module.

The ODBII code U2995 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 U2995 is generally considered moderate.

Common Causes For: U2994 Lost Communication with the Hybrid Powertrain Control Module (HPCM) A.

• Faulty Vehicle Dynamics Control Module (VDCM)
• Corrupted or damaged wiring/connectors
• Poor ground connections
• Communication issues between modules
• Software or firmware issues in the VDCM
• Faulty sensors related to vehicle dynamics
• Low battery voltage or electrical system issues
• Interference from aftermarket modifications or devices

Common misdiagnosis for U2995 Invalid Data Received from Vehicle Dynamics Control Module.

• ABS Module Failure
• Wheel Speed Sensor Issues
• Traction Control System Malfunction
• Steering Angle Sensor Fault
• Brake System Problems
• Wiring or Connector Issues
• Powertrain Control Module (PCM) Fault
• Electronic Stability Control (ESC) Malfunction
• Faulty Vehicle Dynamics Control Module
• Incorrect Tire Pressure or Size

Common Troubleshooting Steps

When dealing with the OBD-II code U2995, 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 related trouble codes. This can provide more context and help identify if there are other issues affecting the vehicle.
• Inspect Wiring and Connectors:
• Visually inspect the wiring and connectors related to the Vehicle Dynamics Control Module (VDCM). Look for signs of damage, corrosion, or loose connections that could cause communication issues.
• Check the Vehicle Dynamics Control Module:
• Ensure that the VDCM is functioning properly. If possible, test the module with a scan tool to see if it responds correctly to commands and queries.
• Inspect the CAN Bus:
• The VDCM communicates over the Controller Area Network (CAN) bus. Check for any issues with the CAN bus wiring, such as shorts, opens, or interference. Use an oscilloscope if necessary to monitor the CAN signals.
• Check Power and Ground:
• Verify that the VDCM is receiving proper power and ground. Use a multimeter to check voltage levels at the module’s power and ground pins.
• Look for Software Updates:
• Check if there are any software updates available for the vehicle’s control modules. Sometimes, manufacturers release updates to fix bugs or improve communication protocols.
• Reset the Codes:
• After performing checks and repairs, clear the trouble codes using the OBD-II scanner 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 U2995 code or the VDCM for your specific vehicle make and model. Manufacturers may have documented common issues and fixes.
• 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.
• Replace the Module (if necessary):
• If all other troubleshooting steps fail and the VDCM is determined to be faulty, it may need to be replaced. Ensure that the replacement module is compatible with your vehicle. By following these steps, you can systematically diagnose and address the issue related to the U2995 code.
