Dreaded U11E9 Code

[Brandon.Pasley]

I’ve read through several posts on multiple sites on this and can’t quite resolve my issue. Recently bought a 2020 Ram 1500 Big Horn with the 5.7 and the code popped up. I’ve unplugged my AAD, cleared codes, checked voltage on the power wire, 12.6v, verified continuity to the ground wire and checked voltage on the bus wire, 10v (all through the AGS plug.). Fuse is good. Code keeps popping up after driving a little. I stripped wire from the AGS plug back to where it converges into the wire bundle and don’t notice any issues. The shutters move freely and after manually closing the shutters, when starting the truck the open but do not cycle after subsequent starts. Not sure where to go from here. Don’t mind not having the AGS but hate the CEL and not being able to remote start. Any help would be greatly appreciated.

Pretty sure that is the fail-safe when there is loss of comm`s.
