900rmk Check Engine Light

hey sledders my first post of the year.We have a 05 900 rmk 159.The check engine light comes on after about 5 min of trail riding then goes off.The sled runs perfect,does not over heat,it has 42 hours on the engine according to the digital display.On the digital display when you go through the menu it says 50 hour service.Could the 50 hour service interval be tripping the check engine light?Just thought I would ask everone before hauling it 80 miles to the dealer.Thanks for your input.Later Trenhdigger
