Sorry to comment on this thread after several years but I have a couple of questions please. My friend has a repair shop and has an Autel Maxisys Elite scanner and a subscription to Auto Auth and I want to see if that set up would allow me to program the BCM to recognize some upgrades to my 2019 RAM 1500. so… 1.) Not arguing just looking for clarification please. I thought having a subscription to Auto Auth for the FCM vehicles meant that you didn’t need a separate cable to connect the Autel scanner directly into the security gateway module but only had to plug directly into the OBDII port? Please clarify 2.) if I want to make upgrades to certain features on my RAM 1500 like adding bed lights, a bright smart mirror (auto on/off high beams) or program a replacement key (that has the auto open tailgate button) and have the proper hardware for these features can I get the vehicle to recognize and operate these upgrades by programming the BCM, etc. with an Autel scanner and a subscription to Auto Auth? Thank you for your reply.
