Scenes from the highway shoulder...
The ol' RGS let me down last night.
I took a nice little ride outside of the city after work yesterday evening, and the weather was excellent. I figured on 60-70 miles and was thoroughly enjoying myself. Shined up nice, running great, feeling good. On my return trip to home, I decide to take the freeway for the remaining 10 miles. As I made my right turn onto the on-ramp, the engine just gently stalled without fanfare. Not a single hiccup prior to that. I glided to the shoulder and attempted to restart. Nothing. Not a click, grunt, nothing. All indicators working, about 12.5v showing on the gauge. Clicked over the kill switch a couple of times just for the sake of elimination. Still nothing.
Roadside code check:
P1511 EFI Power Management Mode
P1514 ETC Air Flow Fault/Error
P2105 EFI Forced engine shutdown
P2135 TPS Correlation Error
After clearing the codes, the bolded ones came back immediately as hard faults. The bike did crank and start after clearing, albeit in limp mode. Fortunately my buddy was able to get my trailer to me and we loaded up my bike and hauled it home without further incident.
Tonight I will be doing some diagnosis, and worst-case scenario will be a failed throttle body assembly. It's a Screamin' Eagle unit, and if that's the failed component, I really, really hope I can get one in time to keep my appointment with Fuel Moto next month. I still have the stock unit sitting on a shelf in my garage, and that'll be my test equipment used this evening, along with my PV2. I'll follow up on the thread when I figure this out. Wish me luck!

Well, the fix was a bit simplistic: a little thing called "terminal abrasion". If the pin fit between a male and female terminal is anything less than tight, vibrations can cause them to "abrade" against each other, resulting in something similar to corrosion. The throttle body pins (both male and female) are gold-plated on 2010-on model years, and therefore practically impervious to chemical-reactive corrosion. But they are not impervious to abrasion.
Long story short, I took the TB connector apart and polished the offending terminal, pinched it slightly for tighter pin-fit, and Bob's your uncle. She's running normally with no codes.
As an aside, the early drive-by-wire models did have corrosion issues on those pins, and my codes lined up with that issue and led me to the root cause after researching the internet.
This fix cost nothing but time. Hallelujah!

Hey Strych9, sorry to hear about your troubles. I noticed in your 25k service thread that you are running a PV Target Tune, any chance that this could be the culprit? In my hours and hours of researching TT before purchasing one, I saw a few instances where the O2 sensors had gone bad or where loose wiring (at the TT module itself) had caused some funky issues with the bike.
Just a thought. Hope you get it sorted out quickly and painlessly either way.

Sorry about this man, I'm sure you'll get it figured out before your FM appt. But obviously, you've put over 25k on it, so odds are something might give out after that many miles. Hopefully its a simple fix.

undoubtedly you'll get things sorted out and back to riding soon...of all the bad things that can happen and places to be when a bike just up and dies on you, just glad to hear it was where it was and you were safe!!!

Thanks, brother. All things considered, the positives are that I was fairly close to home, was able to get it home without a paid tow, and the failure is relatively minor. Cash and time will git 'er done. Hopefully less than more.
