I'm a new member to the Forum but have been following for a while. I have just got a 2019 Ram 3500 Limited and did a bonehead move. Using Alphaobd I changed the tire size since it has 35 inch tires and all went well. I thought. When I headed down the road I noticed I had no cameras, back up, cargo, front or surround so when I got back and here is the bonehead move I got back on Alpha and decided to change camera settings in the vehicle change section without making a copy of my BCM. Everything is working on the truck, except cameras no check engine or fault codes are showing up so my question is do I go back and unchange what I did since Alpha keeps a file or does anyone have a list of what the settings should be for a 2019 with the mentioned cameras and why did they go out to begin with when I didn't change anything on them originally.
