Have a check engine light, and using a jumper, got trouble code 21, active muffler control. I just wrecked the bike, and as of right now it's the only issue I'm still having. I popped the air box off and tried to go by a PDF to double check the unit, but I didn't get much out of it. I'm probably not performing the tests right, but it's still disconcerting that I can't get the unit to do anything. I can pull on the cable and hear the valve opening and closing in the muffler itself, so I know it's not that the muffler got dented in the crash or that the cable was broken, and the ECM is working fine in every other way that I can think of, so I'm pretty sure it's not that. Only things that I can think of are either a short or the unit, and from what I could see, there weren't any frayed or broken wires running to the unit. My money is on the unit itself, but is there any for sure test of the unit itself, like a way to hook up a battery and run the little motor inside and see if anything moves? I'd love to just get it fixed and not have to go back to my dealer with it. |

In ECMspy you can run a diagnostic test on it. It seems to be a common failure lately, I believe Buell got a bad batch. |

Well, I figured out what it was. Short version is the fuse block diagram on the bike isn't worth crap. Slightly longer version is when I crashed, I broke my left hand control group, causing a short, which kept on blowing the fuse. According to the on bike reference, the fuse it blew only controlled the horn and brake. I found a decent diagram online which showed that it also controlled the active muffler. Replaced the control group, changed the fuse, and no more check engine light. Why does every vehicle manufacturer have to group the weirdest stuff when it comes to the fuse panel? I know that you need to group things so that they can run off a certain strength fuse, but come on... |

I don't know why they put it on the horn/tail light fuse, but I recall reading that horn and tail light are grouped together by law. Your car is the same way.
Glad you got it figured out. |
