RZR 800 Specific Discussion AWD code 520 207 4 August 6, 2015 i have a 2014 RZR 800 with 150 miles that has this code. Checked everything I know to check. Finally carried it to the dealer. They said the Ecm was bad. 700$. I saw somewhere that it could be the main fuse. 30 amp. Any thoughts on this?
