Hello
My problem was after last update the system and diagnosis became slow,the codes with"permenant" code case after maintenance didn't erases easily before the last update there was no permenant codes and it waseasiley removed after the right maintenance. For Ford cars the diagnosis give me there's is trouble codes when I enter to read codes it gives me that there is no code.

All that problems make the work hard and also too slow and for ford I can't determine the trouble codes.
Thank s
