Is the Trailer module pre programmed for your application or blank ? IMO ,The truck is just too new to trust Autel maxisys alone performing a parameter reset that in essence performs a Ford Network B@tch Slap to get all the ducks in a row on the network to talk to the new ugly duckling trying to get online. If a parameter reset fails  you may have to tow it to dealer if  Sh@t happens and all the keys have to be reprogrammed again, you'll pay money on a 2 day sub with FJDS (no more FMP) . The 2017 truck probably has coded PATS which require IN Code and Out Code from dealer and that you have a LSID to be verified before you can do the keys. Good luck trying in the dealer service lot.
