The best thing that you can do to save money and headaches, is to learn how you can diagnose vehicle problems yourself.


You don’t have to take the vehicle to the dealer every time a malfunction or warning light shows up on the dashboard. We designed the YOUCANIC scanner to show all the diagnostic information that you get to see when you visit a dealer.

Keep in mind that fault codes should be researched and often you need to look at other modules to figure out what is really going on with the vehicle. In most cases, multiple fault codes are created pointing to one problem.

With the help of a little diagnostic scanner, you will be able to find out what is going on with your vehicle in just a few minutes. Even if you don’t plan on fixing the problem yourself, you will be able to have a better understanding of what is wrong with your car.
