I asked my dealership to do the same PCM update and the RRT and they wouldn't do them. They said that it didn't pertain to my VIN number so it wasn't relevant. I have a 2018 4 door Rubicon with a build date of 7-18So is this what I tell the dealer I want the below done or are they the same or one supersede the other?
Steering RRT8-054 and 18-19-06-WU
PCM update RRT 18-137
