flashscan v2 error $0312

Hello everyone, Im trying to figure out where to get a stock tune for my truck. the previous owner had it tuned and im looking to do my own tuning to it. I see there are stock tune files available, however without being able to scan it im not sure how to match up the correct tune. any help would be appreciated
thank you
Eric
