It's not a major issue and I don't think pulling the neg would eliminate the code. Maybe somebody else may know more about that but if u don't have a scanner I would just give it a few days. When it happened to me. I just looked at the dash randomly the next day and noticed it wasn't Showing issue anymore. Keep us posted so we can help if that's not the problem but I'm sure u will be fine.
