OpenDiag

The application works with Android devices, and it can only perform diagnostics if you have a special adapter. OpenDiag is one of the best applications for carrying out a set of checks that are able to identify all sorts of faults in your car domestic production.

Support and basic information

The application works perfectly with all branded ELM327 adapters, as well as with the main protocols, namely K-Line and CAN. These days, such adapters are widely available on all sorts of Chinese online stores. These Chinese adapters work on OBD-II protocols, but the software does not support them. This error was detected by a large number of users who purchased the Chinese product. The creators of the diagnostic application have accepted the fact that the application does not work with these protocols, so when you connect a Chinese adapter, the error "Unable to recognize adapter" pops up. If you plan to perform diagnostics by connecting the adapter via a USB cable, you may not be able to use a particular tablet, or smartphone. It is important that your portable device has a built-in USB-HOST function, as nothing will work without it. A big plus for all owners of old gadgets will be the support of the application on quite old devices, which are running Android 3.1 and above.
