I would check all the grounds.
They do that so when we break down and push it home, we can see where we are going.
My wild a$$ guess:There is an issue with a bulb or wire. When the hazards are flashing, the dashboard believes a bulb is burned out. So, it tosses up the 'urgent service' message. Add to that, when the dash has any 'urgent service' message, it is limiting the motor revs...
2) Does anyone here know if the 'Urgent Service' message also causes the ECU to trigger the flashers, in which case it might have been the bike that did this, rather than me hitting the button by accident.
I think you are on to something here. As in, if say the throttle servo is acting up, they may turn on the hazards, and limit the throttle.
...With the distance between dealers the slow "Limp to a Dealer" mode is a sick joke IMHO.
Mine did reset when I turned the ignition (not just the engine cutoff) off and on, and I gather others have had the same experience.Lonelec just shipped my adapter cable and KL-1 adapter (hurray!), so I'm hoping I'll be able to check the OBD codes this week. The theories so far as1) Evil MAP sensor.2) Throttle motor has decided to rebel against its overlords.3) It's been using some oil, this has fouled a lambda sensor, and lambdas have taken advantage of this to slip past the guards and wreak havok.4) Space aliens. I beleive that's OBD code P9909.5) There will be no code, leaving me to wait, worry, and wonder...I'm hoping it's not 5 because that would not be emotionally satisfying, but we shall see...
Could it be the oil pressure sensor/connector? Now that you know it is not an accidental bumping of the hazard switch, have you been able to put together the situation or establish a common pattern? I.E. bouncing off rev limiter, lugging, miss shift or over-rev on downshift? Or does it just randomly happen?
It's only happened 2-3 times in 16 months, and the first 1-2 times were so insignificant I didn't even realize it might be a thing, so I'm relying on some very unreliable memories when I search for patterns. The only common thread *might* be 'rolling on lots of throttle uphill or at speed after an extended period at lower revs'. I could make up any number of scenarios for that one. Bouncing off the rev limiter seems unlikely, but I suppose it could have happened, so I'll take your advice and number this among them. Thanks!My plan remains wait for that OBD cable adapter to arrive, try to read some codes, if I find some, assume that's the problem and go from there, and if I don't find any codes, head out to the same place it happened last Saturday and try to reproduce everything I did... with the OBD reader handy in case anything shows up. The start of next step of this investigation will be determined by the speed of international airmail from the fine fellows at Lonelec, who were quite quick about getting that order off.
Thanks for the info about the lamba sensor and rev limiter. I too have bumped into the latter without incident (hooligan me!) but every clue helps.Poking around Guzzitech, I see a case of a Cal 1400 (which i gather has the same ECU) with a much more severe bit of similar-seeming behavior that threw a P0155 code and I gather they eventually traced back to the throttle position sensor. This might be something to think about when and if I finally have a chance to check for codes. I very much suspect the ECU has already reset, because that's the way our Robot Overlords work, and I'll be reduced to nipping around and waiting for the behavior to recur so I can whip out my OBD reader, plug it in, grin smugly, and say, "Ah ha! Take that, Robot Overlords! I have Thwarted Your Nefarious Plan!"If all goes well, the cable adapter should show up this week so I can begin some Plan Thwarting.As I'm sure you all can guess, this is still in that blissfully ignorant Hasn't Caused Any Serious Inconvenience Of Cost Any Significant Amount Of Money So It's Still Sorta Fun stage of engine diagnostics. Will the saga remain this benign? We shall see...
Part of me hopes that you don’t get it sorted...
