So I just recently purchased a john deere 9220 on Tuesday. Well tonight (Thursday) I was running it and all of a sudden the "elect" "information" and "read manual" lights all came. So of course I go into a panic mode as I'm going from a deere 8960 to this and not used to these type warnings. Also tractor didn't come with a manual so couldn't look in there. Anyway after 30 mins of looking around the cab I see this button that says "# code" so I pushed it and I got an ASU then a 111. Well after seeing that I shut the tractor down and let it sit 20-30 mins and fired it back up and everything was clear. No warning lights and no code. Anyone have any idea what this is, how to fix it, and what it cost?
