Maxisys Elite  its autel's finest. this great tool from autel  has the same (none- functionalities) as the rest of them  the only different is, its much faster to give you all the error messages  (this function is not supported ) but on a retina screen very clearly.   it is much easier to guess the lottery than which vehicle function or feature will be available.

If there is no add key option under Pats function, it means this function on this car hasn't been developped.
