Understanding the “Can Not Ready” Message
This message essentially means the VCDS software cannot establish a stable connection with the vehicle’s control modules. It’s like trying to make a phone call, but the connection keeps dropping. This prevents the software from performing any diagnostic functions. Several factors can cause this communication breakdown, ranging from faulty cables and incorrect software settings to problems within the car’s systems themselves.
Common Causes and Solutions
Interface and Cable Issues
One of the most frequent culprits is a faulty or incompatible interface cable. The cable acts as the bridge between your computer and the vehicle’s OBD-II port. Ensure the cable is securely connected at both ends and check for any visible damage like kinks or fraying. Using the correct cable type for your vehicle and VCDS version is vital. If you suspect a cable problem, consider testing with a known working cable. You can learn more about related interface issues in our interface not found vcds article.
Incorrect Software Settings
Sometimes, the issue isn’t hardware-related but stems from incorrect software configurations within VCDS itself. Double-check the options selected under the “Options” tab, ensuring they align with your specific interface and vehicle model. The incorrect baud rate setting can hinder communication, so verify you’ve chosen the appropriate one.
Vehicle-Specific Problems
Certain vehicle models are known to have specific quirks that can trigger the “can not ready” message. For instance, some Audi models require the ignition to be switched to the “on” position, even if the engine isn’t running, for the VCDS to connect correctly. Refer to the VCDS forum or Ross-Tech’s website for information related to your specific vehicle. You might find useful information regarding specific models like the Audi A6 in our audi a6 vcds guide.

Driver Issues
Outdated or corrupted drivers on your computer can also interfere with the VCDS software’s ability to communicate. Make sure you have the latest drivers installed for your VCDS interface. Uninstalling and reinstalling the drivers can sometimes resolve persistent issues. Downloading the right version of the software is essential too, as highlighted in our vw vcds download resource.
What if the problem persists?
Even after trying all the above solutions, if the “can not ready” message still haunts you, the problem might be more complex. It could be a faulty control module in the vehicle or a more intricate software issue.
Troubleshooting Tips and Tricks
Here are some additional tips for tackling this frustrating problem:
- Check your OBD-II port: Ensure the port itself is clean and free of debris. A dirty or damaged port can prevent proper communication.
- Test on a different vehicle: If possible, try connecting your VCDS to another compatible vehicle to isolate whether the issue lies with your car or the diagnostic setup.
- Restart your computer: Sometimes, a simple reboot can resolve software conflicts that may be interfering with VCDS.
- Consult online forums: The VCDS community is vast and helpful. Search for similar issues on forums like Ross-Tech’s official forum to see if others have encountered and resolved the same problem.
