A few days ago on the way home from work, I fueled up and topped off the gas just below the overflow level of the tank. I took off and within a minute had to make a sharp right bank onto the highway. As I started into the cloverleaf, the bike died... speedo lit up like a Christmas tree with all sorts of lights going off - I noticed the 'error' light (red) and the battery light was also red.

I didn't panic, but did quick diagnostic and noticed a bunch of errors. I kick myself for clearing the first which I cannot even recall what it was, but the others were:

B2104 System Power Output Overloaded
B2263 Hazard Switch Stuck
U0121 Lost Communication With ABS

I turned the bike off and then started it again and have no issues since. I am having a hard time believing that it was due to a full gas tank but perhaps it was?

Nothing else was running, i.e. no heated gear, etc.
Just wondering if anyone else has had this issue.

 

Gremlins -

 

They all do that!

 

suggest you get the bike running in the driveway ( with fans pushing air) and manipulate any part of the wiring harnes you can- with special attention to any areas that have been modded ( bars?).

If you find nothing, kick or whack the tires with a ballbat, bounce on the seat etc.

battery cables tight? ( the system power code has me wondering)

and lastly i'd disconnect and reconnect he ecm.

if your bike is stock- you have a warranty, take it in

Check wiring harness around steering neck to see if it is chaffed from turning bars.

 

There was an ignition switch recall on some models. Check and see if yours is one of them.
My 2016 low-rider did the same thing and had me stumped. Had it towed home and it started after it left the truck and ran fine every time after.
Then about a month later I got a call about the recall.

 

That recall only affected the Dyna models.
None of the touring models are part of it.
