I have a 2005 Ram 1500. The battery is not charging. " Check Gauges" light on cluster stays on. So far, I've had the alternator tested, put in a new battery, ordered a rebuilt computer and installed it, and ran the code test which gave code P0622. I also ran the gauge test and got codes AA 10, and AB 10. What is the AA10 and AB10 meanings, and what should I try next? The computer I replaced was the one mounted at the firewall on passenger side secured with 3 screws and has 4 plugs. Any help is much appreciated.

Did you get this figured out? I'm having the same issue in my 2003 Ram 1500 5.9 liter.
