Engine codes
I could use some input...I have a '24 Breakout with about 9500 miles on it. Following an uneventful 20 mile ride home from work tonight, I stopped for gas. After the fillup, I started the bike and it didn't want kick over right away, lights went out, clock reset, etc etc. 2nd attempt it started, but immediately went into limp mode with a high idle, and kicked out the following codes:
P1511h
P1100h
P0120c
P0220c
C1100c
B2156h
B2151h
Took pictures of all the codes, and let sit for about 5 minutes, then cleared them out. After that the bike started and ran normally the rest of the way home...bit it was only a mile or so. After an hour in the garage, I started it again, still running normally, no codes.
Only mods are some Cobra slip-ons that have been there since day 1, and a Wilburs suspension that went in about a year ago. A couple of times over the last couple of weeks when idling at a traffic light, the idle speed would randomly go up slightly from ~850-900 to roughly 1000-1100 rpms.... just enough to notice. A quick burp of the throttle, and the idle went back to normal. Only did it a few times...so both the current and historic codes related to the TPS sensor don't surprise me. But the ones related to the ABS and the turn signals are a bit more puzzling. I did replace the stock signals with LEDs, but that was also done shortly after i got the bike, so they've been there quite a while, too. I've had no issues with the brakes.
It's gonna go to the dealer regardless, as it's close to the 10K service anyway, but I figured I'd pick the brains around here. Any thoughts?
You mentioned the bike didn't want to start and I wonder if that was when there was a very high load on the battery? An anomaly with the starter motor pderhaps.
Another reason can be a loose connection that is high resistant which also causes a drop in voltage when trying to start the engine.
