OK On my 2018 Diesel, the one that with the trailer plug next to the brake unplugged would not shut off AS*, disconnecting the BMS sensor does and it works! Just says VEHICLE ON DUE TO CHARGING, according to everything I read this is what is to be expected and actually better for the battery, since it will now fully charge.
My Raptor with the trailer plug unplugged always said VEHICLE ON DUE TO TRAILER. Is this works, this is awesome!
I am going to hook up ODBWiz/Forscan in a moment and see what I am charging at.
