U2653 – Invalid Data Received from Vehicle Dynamics Control Module.

The ODBII code U2653 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 U2653 is generally considered moderate.

Common Causes For: U2652 Invalid Data Received from Vehicle Dynamics Control Module.

• Faulty Vehicle Dynamics Control Module (VDCM)
• Poor or damaged wiring/connectors between the VDCM and the ECU
• Corrupted or incompatible software in the VDCM
• Faulty sensors related to vehicle dynamics (e.g., wheel speed sensors)
• Communication issues within the CAN bus network
• Low battery voltage or electrical system issues
• Grounding issues affecting the VDCM or related components

Common misdiagnosis for U2653 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 (VDCM)
• Incorrectly calibrated or programmed modules
• Battery or charging system issues

Common Troubleshooting Steps

When dealing with the OBD-II code U2653, 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. Sometimes, multiple codes can provide more context for the issue.
• 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.
• 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 according to the manufacturer’s specifications.
• Inspect Related Modules:
• The VDCM may communicate with other modules in the vehicle. Check for any issues with these related modules, as they could be causing the invalid data error.
• Look for communication issues between the VDCM and other control modules, such as the ABS module or the engine control module (ECM).
• Check Power and Ground:
• Ensure that the VDCM is receiving the correct power and ground signals. Use a multimeter to check voltage and ground connections.
• If there are issues with power or ground, trace the wiring back to the source to identify and repair any faults.
• Perform a System Reset:
• Sometimes, clearing the trouble codes and performing a system reset can resolve temporary communication issues. After clearing the codes, 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 U2653 code or the VDCM for your specific vehicle make and model. Manufacturers may have issued updates or fixes for known issues.
• Professional Diagnosis:
• If the issue persists after performing the above steps, it may be necessary to seek professional assistance. A qualified technician can perform more advanced diagnostics, including using specialized equipment to test the VDCM and its communication with other modules.
• Replace the Module (if necessary):
• If all other troubleshooting steps fail and the VDCM is determined to be faulty, replacement of the module may be necessary. Always refer to the vehicle’s service manual for specific procedures and specifications related to your vehicle model.
