2013 sporadic DTC issue

A couple weeks ago the bike was set down at zero speed on the left side; no damage. A few days later, after a couple of other no-issue rides and while riding in the wet, the DTC started flashing like crazy at a speed under 30 mph completely upright. Cut the power so much I nearly stopped in the middle of traffic before I realized the cause.

Since then the DTC issue would come and go (seemingly randomly) over a series of different rides. Speed and angle didn't seem to matter much.
  • I have Q3's which have been on the bike since last summer and have done street and track with no previous DTC/ABS issues.
  • The sensor rings are perfect and firmly set in the stock wheels.
  • The sensors have been cleaned by hand with soft cloth and look to be proper distance from ring.
  • No wheel removal anytime near the issue occurrence was done.
  • Wires from both sensors in perfect, like-new condition.
  • Tire air pressure is at street levels.
  • Bike was ridden in Sport mode.
  • GS-911 reports no codes that matter to the issue.
  • ABS operates just fine.

Reading a thread on here about the action of DTC in each mode gave me the idea to hit the street in Race mode. No DTC issues. Rode it for ~10mi and then switched back to Sport mode for ~2mi. No DTC issues. I'll keep it in Sport for my trip to work tomorrow and see if the problem self-corrected. Maybe I'll get lucky.

Is there a way to see, using GS-911, the sensed speed of each wheel? Link would be great
Where can I find the gyros for lean angle? I want to check their physical condition.

Ride it like you stole it.

Although there is no sensor error, I would consider replacing it.

The GS-911 should be able to read the status of wheel speed sensors. Put the bike on some pit stands so both wheels are off the ground and spin the wheels while watching to see if the value changes on the GS911.

Since the issue has stopped I don't plan to make a $150 investment but if I did which sensor would you replace, @sro?

@benny, I assume those values show AFTER I've registered the VIN. Wasn't going to do that until I needed to but this makes the case. Thanks.

I had a problem similar, did u check the battery posts?
If u have the stock battery, or replaced it with the same cheap box post Yuasa as the stock one, one or both posts could have a hairline crack. You won't likely see it unless you disconnect the battery, remove it, use a light and magnifying glass to check each side of both posts. Could have stress cracks from sudden tipover.
On the other hand, the terminal screw(s) could be loose, and you simply need to tighten them. Not too tight, they crack really easy.

If you find you need a new battery, "batteries plus bulbs" carries one (forgot brand name) that's around $65, and has brass terminals, that are a lot stronger than the b.s. crap metal the OEM yuasa.

I would replace the front sensor since it is on the left side.

Final follow-up for reference. Didn't change any parts, just changed modes to rain and race and rode a bit and the issue went away on its own. Peculiar.
