I don’t recommend it to solve problems because you still have to go to see a mechanic and he uses his own tools. But you can delete old codes that doesn’t really help because they are already inactive.

There’s so many other truck diagnostic options nowadays on Amazon etc that the high price is no longer justified for this market. The Ai option is mediocre, it’s better to plug in those codes into other Ai models and often get a better explanation.

App constantly disconnects from device, can no longer clear generic codes ( like the whole command option disappeared), and forced regen is no longer consistent. Also when you are trying to find out about the codes you have the AI assistant will not work it’s very inconsistent. When it does work it asks you to do things so it can help further diagnose the issue but the things it asks you to do you don’t even have the option to in the app. 6.7 isb Cummins engine International truck. This app use to work but it seems like the update messed some things up and I don’t know if they are trying to fix it
