U2659 – Invalid Data Received from Vehicle Dynamics Control Module.

The ODBII code U2659 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 U2659 is generally considered moderate.

Common Causes For: U2658 Lost Communication with 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
• Malfunctioning sensors related to vehicle dynamics (e.g., wheel speed sensors)
• Communication issues within the CAN bus network
• Low battery voltage or electrical system issues
• Faulty ECU (Engine Control Unit) or other related control modules

Common misdiagnosis for U2659 Invalid Data Received from Vehicle Dynamics Control Module.

• Faulty ABS module
• Incorrect wheel speed sensor readings
• Wiring issues or shorts in the communication lines
• Faulty Vehicle Dynamics Control Module (VDCM)
• Issues with the power supply or ground connections
• Problems with the Engine Control Module (ECM)
• Incorrectly calibrated or configured sensors
• Software or firmware issues in the control modules

Common Troubleshooting Steps

When dealing with the OBD-II code U2659, 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: Examine the wiring and connectors related to the Vehicle Dynamics Control Module (VDCM). Look for signs of damage, corrosion, or loose connections that could affect communication.
• Verify Power and Ground: Ensure that the VDCM is receiving the proper power and ground. Use a multimeter to check voltage and ground continuity at the module’s connectors.
• Check for Software Updates: Sometimes, the issue can be related to outdated software in the vehicle’s control modules. Check with the manufacturer for any available updates for the VDCM or other related modules.
• Inspect the Vehicle Dynamics Control Module: If the wiring and connections are good, the issue may lie within the VDCM itself. Inspect the module for any signs of physical damage or water intrusion.
• Perform a Network Test: Use a scan tool to check the communication between the VDCM and other modules on the CAN bus. Look for any communication errors or issues with other modules that may affect the VDCM.
• Clear Codes and Test Drive: After performing the above checks, clear the trouble codes and take the vehicle for a test drive. Monitor for the reoccurrence of the U2659 code.
• Consult Technical Service Bulletins (TSBs): Check for any TSBs related to the U2659 code or the VDCM for your specific vehicle make and model. Manufacturers may have specific recommendations or known issues.
• Replace the Module (if necessary): If all other troubleshooting steps have been exhausted and the issue persists, consider replacing the Vehicle Dynamics Control Module. Ensure that the replacement module is compatible with your vehicle.
• Professional Diagnosis: If you are unable to resolve the issue, it may be best to consult a professional mechanic or technician who has experience with your vehicle’s systems. By following these steps, you can systematically identify and address the root cause of the U2659 code.
