Welcome to the forums. I wish I could help, but I don't have the Rincon 680 service manual and I don't have the codes. Maybe someone that has the Rincon 680 service manual will post the codes for you.
I have a Rincon 650 service manual, but the 650 is carbed and the 680 is fuel injected, so the codes won't be the same.
Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!
You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.
