I bought new a 2019 Sportsman 450 @ 6 months old had a check engine lite come on. I'm unable to get to the diagnostic code screen on the instrument cluster as per owners manual. I had changed Oil and filter prior to this issue. It still runs good. I can clear the lite by multiple pressing of the mode and arrow buttons. But lite comes back on after a while. Dealer wants $150 to inspect it. As now it's not covered under warranty. Any assistance would be appreciated.
