2006 RMK 700 check engine light while running

[dirty530]

I have a 2006 RMK 700. I did my normal start up routine, let it warm up and all that good stuff and I got like a mile down the trail and the check engine light came on. It blinks 5x then pauses 5x then pauses 5x then pauses. Anyone know what the error code/problem for this is?
