The saga continues.

They called me to come pick it up yesterday "we even washed it for you". The paperwork says they replaced the exhaust valve actuator and reset codes. Long story short, I ride off and not two miles later the exact same thing happens again-CEL comes on and the damn interactive exhaust valve starts cycling again. I can see the actuator right through the airbox cover moving the cable back and forth. Bike runs like absolute crap, which may be some kind of limp mode. Turned around and rode right back to their door and they are dumbfounded. Needless to say, week 2 of ownership and it has resided at the dealer for a week.

If the actuator is moving back and forth, it's working!!!! Something is telling it to move.......ECM maybe????? Programming???? :frown2: You ain't gotta be the head cashier at the WallMart to figure that out....
 
You and I know that, but getting it through their collective heads has not been too easy. I'm going to try to convince them to either replace the ECM with another one or try again to re-flash this one even if it's with the same calibration.

This may be here nor there, but both times it's freaked out now have been occasions where I've shut down and re-started it while it was hot and the cooling fan was still running.
 
In theory it shouldn't matter, but it could be a bad or inadiquite ground. My Triumph had a glitch after I first bought it. It would stumble and die at times. Happened once in a blue moon at best, but I still brought it in, just incase. There was a TSB to replace the ground wire to the ECM with a larger wire. Fixed it.

If your fan is on and you are trying to start the bike, it might be pulling enough of a load on the electrical system to somehow 'spike' the ECM or not enough power to properly turn on the ECM?? causing it to either, fry the programming or protect itself, somehow?? Wrong wire size or poor ground will easily do something like this.

Just a thought.:)
 
We're actually riding today :)

I forgot to update this...
The dealer got in touch with tech svcs, gave them the codes and symptoms, and the tech guy asked whether the dealer had adjusted the exhaust valve lash via the cable upon PDI. They did not, and as a result the actuator couldn't report fully open or fully closed to the ECM, causing it to throw the codes for stuck, high and low exhaust valve position.

Think of the VNT on (most of) our trucks... it cycles open and closed fully at idle so that the ECM can learn the vane position, causing that funky change in exhaust pitch. Same principal, but the valve in the muffler is controlled by a cable that needs to have the proper tension before it will learn fully open or fully closed.

Long story short, they adjusted the cable and reset the TPS to clear the stumble off idle and I have been riding happily since Tuesday!
