Invalid Data Received from Vehicle Dynamics Control Module
A communication error with the vehicle dynamics control module has been detected.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The vehicle's computer is reporting that it's not getting valid information from the vehicle dynamics control module, which helps with handling and stability.
What the computer is actually seeing
The main computer is trying to read data (like speed or yaw rate) from the vehicle dynamics control module but is receiving unexpected or corrupt data leading to a communication fault.
What a healthy reading looks like
The signal from the vehicle dynamics control module should typically be a CAN message with valid parameters related to steering angles, speed, or acceleration; if data is outside normal ranges (e.g., speed showing 0 when the vehicle is moving), fault triggers.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the vehicle's battery voltage. Should be above 12.4 volts. If low, charge or replace battery.
- 22. Inspect wirings and connectors leading to the vehicle dynamics control module for damage or corrosion. Repair as necessary.
- 33. Use a scan tool to check for any other codes that may be related. If present, address those first.
- 44. With the vehicle running, monitor the data stream from the vehicle dynamics control module. Look for expected values (speed, yaw rate). If readings are erratic, proceed to the next step.
- 55. If the module is getting power and ground, and data is still invalid, consider replacing the vehicle dynamics control module.
Common causes
- Faulty vehicle dynamics control module
- Wiring issues (torn or shorted wires)
- Corroded or loose connectors
- CAN bus communication faults
- Software glitches in the control module

Frequently asked questions
Is it safe to drive with this code?
Yes, but be aware that stability and handling features may be affected.
Will this code come back after clearing?
If the underlying issue isn't fixed, the code will likely return.
Why does this code pair with U0422 or U0423?
Those codes also indicate communication issues with other control modules in the vehicle's system.
