I have a 2022 Ram 3500 with the standard output 6.7L and it's throwing the U11E9 permanent code (Lost communication with AGS system). I have confirmed that the plug on the bottom of the grille shutter it self has +12v and gnd in the right places. the only other wire on it is what I believe to be a direct signal connection to the engine ECM. I can't seem to find an ECM pinout to check continuity between the ECM and the AGS plug. The truck was previously totaled and has been rebuilt.
Thanks in advance
