Usually, when you see that wide variety of errors, it's from a low 12 volt battery. That isn't to say that there isn't something real in there, just that you have to eliminate the accessory battery issue, clear the codes, and then see what persists, if anything. It may take several tries, and disconnecting the 12 volt battery, to get them to clear. If that 12 volt battery isn't virtually new, I'd get a new, 51R configuration battery - preferably an AGM type, as those batteries are more tolerant of deep discharges. Make sure it's fully charged before installing it.
