U2695 – Invalid Data Received from Vehicle Dynamics Control Module.

The ODBII code U2695 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 U2695 is generally considered moderate.

Common Causes For: U2694 Invalid Data Received from Vehicle Dynamics Control Module.

• Faulty Vehicle Dynamics Control Module (VDCM)
• Communication issues (wiring or connectors)
• Corrupted or incompatible software/firmware
• Faulty sensors related to vehicle dynamics
• Power supply issues to the VDCM
• Grounding issues
• Interference from other electronic modules
• Damaged or frayed wiring harnesses

Common misdiagnosis for U2695 Invalid Data Received from Vehicle Dynamics Control Module.

• Faulty ABS module
• Defective wheel speed sensors
• Malfunctioning traction control system
• Issues with the vehicle’s wiring harness
• Problems with the powertrain control module (PCM)
• Incorrectly calibrated or faulty steering angle sensor
• Faulty brake control module
• Software issues or outdated firmware in the vehicle dynamics control module

Common Troubleshooting Steps

When dealing with the OBD-II code U2695, 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.
• Ensure that all connectors are securely attached and free of dirt or moisture.
• Check the Vehicle Dynamics Control Module:
• If the wiring and connectors appear to be in good condition, the next step is to check the VDCM itself. This may involve testing the module for proper operation or checking for software updates.
• If possible, perform a reset or reprogram the module to see if that resolves the issue.
• Inspect Related Modules:
• Since the VDCM may communicate with other modules (like the ABS, traction control, or stability control modules), check those modules for any fault codes or issues that could affect communication.
• Test Communication Lines:
• Use a multimeter or an oscilloscope to test the communication lines (CAN bus) for proper voltage and signal integrity. Look for any shorts, opens, or noise on the lines.
• Check Power and Ground:
• Ensure that the VDCM is receiving proper power and ground. Use a multimeter to check voltage at the module’s power and ground pins.
• Clear Codes and Test Drive:
• After performing the 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):
• Check for any TSBs related to the specific make and model of the vehicle. Manufacturers may have issued guidance on common issues related to the VDCM.
• Professional Diagnosis:
• If the issue persists after performing the above steps, it may be necessary to seek the assistance of a professional mechanic or dealership with advanced diagnostic tools.
• Consider Environmental Factors:
• Sometimes, environmental factors such as extreme temperatures or moisture can affect module performance. Ensure that the module is not exposed to conditions that could lead to failure. By following these steps, you can systematically diagnose and potentially resolve the U2695 code. Always refer to the vehicle’s service manual for specific procedures and specifications related to the vehicle in question.
