Thanks for the responses. My RGU will be in for a total diagnostic after the 1st of the year to find out what happened. I will post the results after I get them.  Until then, have a safe, healthy and happy New Year!

Ride Safe and Aware

 

 

You have a safe, healthy and happy New Year as well...

Aloha Guys,

Just got my 2016 RGU CVO back from the dealership.    The problem with the Fork Lock message appearing while riding and intermittently shutting the bike down totally or temporarily for a second or two has been resolved.  It appears that member (FLSTI Dave)  was on the right track in his response to my original post.  It appears that a faulty switch in the Fork Lock/Ignition Switch Assembly was sending an incorrect signal (ohms measurement) to the computer telling it that the bike was in Fork Lock mode when in fact it was in the Run position with the engine running, which as we know when the bike is in the Fork Lock position, the computer won't allow you to start the engine. 

They replaced the Fork Lock / Switch assembly (Part # 71400090A) and tested to ensure that the problem was solved.  They are telling me this is probably an isolated incident but will keep track of it. 

Again, I appreciate all the responses and input.

Ride Safe and Aware!

That it's even possible for the switchouse / interlock to fail in such a way that it can force an engine shut off while riding is unacceptable and frightening.  In the automotive world you'd expect a recall.

Absolutely!  While this particular owner may be happy and assume everything is copacetic, when this happens to someone else when they're riding at high speed in heavy traffic that owner may not be so happy.  The fact that this is even possible (engine shutdown while moving due to a bad sensor in the fork lock mechanism) is totally unacceptable and represents p-poor engineering.  If it were mine, I would still contact NHTSA so they will have it on record.  That's how they find out about safety defects and ultimately start investigations that can become recalls.

Really glad you weren't hurt and the immediate problem is fixed.  I'm with those who say NHTSA needs to hear about this ASAP.

This is the problem with any system that uses computer code--it's almost impossible very difficult to test every scenario where something can fail.  And this kind of result (shut down while moving) is even less likely to be tested by "code-writers" if they aren't riders or pilots or factory employees...they don't have experience in that field, so they aren't aware of the problems that can result.  They are working from a set of specs and requirements, and those by themselves may not address unwanted results.  This is all the more reason to report it to NHTSA, etc.

Dave is right, you would not experience fork lock going down the road regardless, unless you have the forks turned to full lock, that is where the "catch" is. Electric problems happen on everything regardless of new or not  and I can not remember ever turning the handlebars to stops at speed.
I see no need to panic here.

Have hit the stops doing a U turn across a little two lane road in a hurry. That'd be a lousy time to have the engine unexpectedly shutdown.

[FLSTFI Dave]

I can see a rapid u turn on a road having it die would be bad, and cause a dropped bike.

That said there are many electrical things on a motorcycle that can cause it to shut down when running.

My 03 Fatboy ride to work back in 05 shut down and cam right back on.  Did this two different times, lights and everything died.

The 3rd time it would not come back on until I cycled the ignition switch several times.  Crappy switch design, I rebuilt it and it worked great for three more years, rebuilt it again.

My 15 CVO Ultra shut down at 80 mph in a group ride on the interstate.  Everything died but it started right back up, that was 20K miles ago.  Have never figured out why, nor has the dealer.  It has happened to one other that I know of.

I think you missed the point Don.  The problem is that the false indication of a locked fork SHUT THE ENGINE DOWN while the bike was in motion!  That is the part that makes this extremely unsafe and a damned good reason to "panic" if it happens to you in traffic.

No, that was obviously the worst issue and the scariest part of the failure.  Was just remarking on the other gent's statement suggesting we'd never actually see fork lock in operation.  Indeed though, the entire "false fork lock" and its consequences were what would cause me to be at the NHTSA website in a heartbeat.

Sorry Don, I was referring to the post from CVODON, not yours.  I know you understand the importance of this.

All good Jerry.  The dogs are sound asleep (and a little gassy) so I like it when anyone talks to me  .

I understand Don, Guess part of it is all the junk I drove/rode in my younger years that has quit/stopped/hood blown up while going down the road and I never thought of getting upset at the manufacturer. I guess that I don't panic as quick as some or maybe I am just not smart enough to be upset. But I understand what you were saying.

Much of the junk I rode when I was young was the same way Don.  Frankenbike machines built of more than one and other mechanical oddities.  There's a difference though between the expectations applied to those contraptions and a factory supplied 35-40k dollar bit of "modern" manufacturing.

I'm with you Don big difference if it was something I threw together out of a bunch of parts from old bikes as a kid.  On a $40,000.00 bike no way.
