I'm having exact same issue. Batt is charging fine, I just recieve "battery not charging" message periodically. Anyone figured it out yet? Thanks

I'm a GM tech. My sons 03 Duramax Sierra does the same thing. I fought with this for days. Even called Gm TAC line asking them. They have no clue either.
Sometimes it does it, sometimes it don't. He has factory dual alternators and thought that may be the issue. Temporarily deleted the aux alt and it still did it.

Best I can figure is it's a poor connection in the harness to IPC connector. It doesn't affect anything so we just leave it alone. It usually shuts off in 30 sec and won't come back on for a few days.
