Can confirm as the other poster said. Scared the **** out of me at first, but works itself out.
So a little update after my panic attack. YES everything came back to normal and I now have full functionality of my trailer brake options including the cluster display pages and the trailer naming options in the settings screens. Just to share what I saw along the way that might help or ease some panic for others along the way.
- the physical installation is detailed perfectly in the original post
- the ALFA ODB programming instructions are great but the app itself has updated a few times since OP and may look a little bit different (it did for me) but let’s be real, if you are capable enough to even be considering messaging with your trucks BCM you will figure it out. I didn’t document the individual drop downs but I know I had to try a couple different versions to find the right one to link to my BCM
- after making the ITBM settings changes I did get the trailer brake on the cluster but nothing else
-yes I did pull the battery positive during hardware installation and in hindsight this is what caused my 12” Uconnect to turn into an Atari 5600 for about 12 hours. I guess better safe than sorry but not knowing it would dump a bunch of options and settings from the screen and take overnight to fix itself caused me some stress. I thought I had ******up my BCM.
-here is a list of things I found missing from the touchscreen
-backup camera. Won’t come on in reverse and all buttons and settings disappear
Air suspension settings MIA but the suspension still worked with height select physical switch
Comfort and convenience lost a bunch of stuff
Trailer brake not yet present in settings (did show on cluster)
At about 10 minutes in the F bombs start at a high RPM
2 hours in and the wife will start yelling out that it’s time to put the kids to bed
The next morning you will run out to check again before you even let the dog out and find everything back to normal and you now have trailer brake in the settings
25% of people also get one more wife yelling out the window “are you friggen serious?? The dog has to pee”. Results may vary
hope this helps someone
