For output of codes and live data on 2018 and up FCA vehicle systems ( other than generic OBD2)that have a SGM module your tool has to have an active update subscription with Autel and initially will require internet connection to Autel's server to download some sort of output authorization code .

   To do any input commands like clearing codes, or doing any Bi Directional active tests(if MK808 can do) then you need to remove dash trim etc to access the SGM module connectors and install The Chrysler 8+12 cable that bypasses the Secure Gateway module.

  I believe you might be able to pay $50 a year to Auto Auth and register all your scan tools so you don't require the 8+12 cable and taking dash trim apart . Call support and ask about your tool working with 2018and newer Chrysler and find out if Auto Auth works for your tool and whether or not that it will continue to work after your update period is over?
