U1428 – Invalid Data Received from Vehicle Dynamics Control Module.

The ODBII code U1428 indicates that the vehicle’s control module has received invalid or erroneous data from the Vehicle Dynamics Control Module, which may affect the vehicle’s stability and handling systems.

The severity of ODBII code U1428 is generally considered moderate.

Common Causes For: U1427 Invalid Data Received from Vehicle Dynamics Control Module.

• Faulty Vehicle Dynamics Control Module (VDCM)
• Corrupted or damaged wiring/connectors
• Poor ground connections
• Faulty communication between modules
• Software issues or outdated firmware
• Malfunctioning sensors related to vehicle dynamics
• Electrical interference or noise in the system
• Low battery voltage or power supply issues

Common misdiagnosis for U1428 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)
• Incorrect tire sizes or pressures
• Software or calibration issues in the control modules

Common Troubleshooting Steps

The OBD-II code U1428 indicates that the Engine Control Module (ECM) has received invalid data from the Vehicle Dynamics Control Module (VDCM). This can be related to issues with communication between modules, sensor malfunctions, or wiring problems. Here are some common troubleshooting steps to diagnose and resolve the issue:

• 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 between the ECM and the VDCM for any signs of damage, corrosion, or loose connections.
• Ensure that all connectors are securely plugged in and that there are no bent pins.
• Check for Software Updates:
• Verify if there are any software updates available for the ECM or VDCM. Sometimes, manufacturers release updates to fix communication issues.
• Test the Vehicle Dynamics Control Module:
• If possible, test the VDCM to ensure it is functioning correctly. This may involve using a scan tool to check for live data and see if the module is responding as expected.
• Inspect Related Sensors:
• Check the sensors that provide data to the VDCM, such as wheel speed sensors, steering angle sensors, and yaw rate sensors. Ensure they are functioning properly and that their wiring is intact.
• Perform a Hard Reset:
• Disconnect the vehicle’s battery for a few minutes to reset the ECM and VDCM. Reconnect the battery and see if the code reappears.
• Check for Ground Issues:
• Ensure that the ground connections for both the ECM and VDCM are secure and free of corrosion. Poor grounding can lead to communication issues.
• Scan for Communication Issues:
• Use a scan tool to check the communication between the ECM and VDCM. Look for any communication errors or timeouts.
• Consult Technical Service Bulletins (TSBs):
• Check for any TSBs related to the U1428 code for your specific vehicle make and model. Manufacturers may have documented common issues and fixes.
• Replace Faulty Components:
• If you identify a faulty VDCM or related sensor, replace it and clear the codes. Monitor the system to see if the issue is resolved. 1
• Seek Professional Help:
• If the problem persists after performing these steps, it may be necessary to consult a professional mechanic or dealership for further diagnosis. By following these steps, you can systematically identify and address the underlying issues causing the U1428 code.
