U2983 – Invalid Data Received from Vehicle Dynamics Control Module.

The ODBII code U2983 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 U2983 is typically considered moderate.

Common Causes For: U2982 Lost Communication with the Steering Angle Sensor.

• Faulty Vehicle Dynamics Control Module (VDCM)
• Poor or damaged wiring/connectors between 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 U2983 Invalid Data Received from Vehicle Dynamics Control Module.

• Faulty ABS module
• Defective wheel speed sensors
• Incorrectly calibrated steering angle sensor
• Malfunctioning traction control system
• Wiring issues or poor connections
• Faulty vehicle dynamics control module
• Software or firmware issues in the control modules
• Battery or charging system problems

Common Troubleshooting Steps

When dealing with the OBD-II code U2983, 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 that could affect communication.
• 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.
• Test the Vehicle Dynamics Control Module:
• If possible, perform a functional test of the VDCM. This may involve using specialized diagnostic equipment to check the module’s operation.
• Inspect Related Modules:
• Check other modules that communicate with the VDCM, such as the Engine Control Module (ECM) or Anti-lock Braking System (ABS) module. Communication issues can sometimes stem from problems in these modules.
• Check for Software Updates:
• Verify if there are any software updates available for the VDCM or other related modules. Manufacturers may release updates to fix known issues.
• Clear Codes and Test Drive:
• Clear the trouble codes using the OBD-II scanner and take the vehicle for a test drive to see if the code returns. This can help determine if the issue was a temporary glitch.
• Inspect for Environmental Factors:
• Consider any environmental factors that may affect the VDCM, such as moisture or extreme temperatures. These can sometimes lead to intermittent issues.
• Consult Technical Service Bulletins (TSBs):
• Check for any TSBs related to the specific make and model of the vehicle. Manufacturers may have documented common issues and solutions.
• Replace the VDCM:
• If all other troubleshooting steps fail and the module is determined to be faulty, consider replacing the Vehicle Dynamics Control Module. 1
• Professional Diagnosis:
• If you are unable to resolve the issue, it may be best to consult a professional mechanic or dealership with experience in diagnosing and repairing vehicle dynamics systems. By following these steps, you can systematically identify and address the root cause of the U2983 code.
