I had the check engine light come on during a ride on some Forest roads. I turned off the bike and restarted and the light never came on again. I took it to the dealer so they could hook it up to the computer and see what the issue was. They said there must have been some debris blocking the fan which tripped a breaker. This caused the check engine light to come on. I guess my question is it tripped a breaker why did the light go off. Secondly my fan has been working all along. I guess it could have been a temporary blockage. Because they said there was still some debris around the fan. The other mystery is how did it get there. I don't remember riding through any brush and the bike was never down. I was riding through some mud. Could that get up into the fan area and cause problems. Has this happend to anyone else.
