That is what I did, appears that it does not show the codes associated with this.
Yes, my truck is an lt with conv package 2. I have played around some with the trailering menu and I have setup profiles for two of my trailers and connected both of them, and it does have the reminders, mileage , and diagnostics. Actually told me I had a bulb out on my stock trailer. Pretty sure I saw a setup screen for the trailer tpms somewhere.
Seeing as how the codes in the door are incomplete, I will definitely do this.
Thanks for all the information.
