That fault code means there is a problem with signals to the ECU. It may be as simple as a loose connection (check couplers in the harness) or it could be a short or even a malfunctioning ECU.

Carnac the Magnificent I'm not, but I do see a trip to the dealer in your future.

I have been getting the same every once in a while...
Do you have a Powercommander hooked up?

People here told me not to worry until it appears while riding, and not when shutting off the ignition...

My gut feeling is it is a precursor to the TPS syndrome...

ER-1

There is a thread about that same exact error a while back, but I can't find it.

I wouldn't worry about it if it happens at shut-downs since the display goes off after the ECU.

Worry about it when it happens at start-ups when the ECU goes on before the display.

Crap, my new bike worked last night and now it's got an error code 12 on it. I guess I get a crash course is "WTF is wrong with my bike and I better fix it now"
