Code 19

[FJR Flyer]

Feeling a little like George Sanderson. I've been struck by Code 19 a couple times, lately. This morning, I rode into work and I was waiting for the garage to open. Went to start it and got the yellow light and code 19. Got this last week at home in the garage. Each time, cycling the key several times eventually cleared it.

After last week's event I did a search and what little was out there indicated that the circuit goes through the ignition switch. I had washed the bike the week before after riding in some nasty rain with salt getting caked on the bike I thought some crap may have gotten into either of the switches. Sprayed some contact cleaner into both switches. And it was okay.

But it came back today. So is there any defnitive check on what the problem is? I had changed out the ignition with the recall and I still have Brody's bypass harness installed.

Don't want to get stranded somewhere.

There are two sets of contacts in the ignition switches. The main set of contacts (that switches the primary current path for the entire bike) is the set that the Brodie Relay bypasses. The secondary set of contacts in the ignition switch just switches the Fuel Injection signal, which is the signal that is interlocked with the sidestand switch and the kill switch. When the secondary set of contacts do not close you get error code 19.

The fact that you have already got it to clear just by messing with the ignition switch suggests you have already isolated your problem to the switch. You can use diagnostic exercise :20 as an indicator of when that circuit has continuity, but you already have that indication from the error code presence.

You need to spray contact cleaner up from the back of the electric switch part of the key switch assembly (there is a weep hole) to get it to the contacts. Spraying down through the key hole will only flush out the mechanical lock cylinder and tumblers, etc.

Fred - Thanks for the quick follow-up. Much appreciated. I will shoot the weep hole today, when (if?) I get home from work.

Got the contacts sprayed with cleaner yesterday via the weep hole. Started okay today. Keeping my fingers crossed.

Related question - best lube for the lock cylinder? Graphite? Silicone?

Dry graphite, so it doesn't run down and foul your clean electrical contacts.

If the switch does start acting up again, you can buy the "upgraded" switch (via the recall parts kit) for much less than the switch alone that is still listed in the parts lists. The Recall procedure shows how to remove and replace the switch assembly and retain your original lock cylinder so your old keys will still work.

Thanks, again. I'll shoot some graphite in it this afternoon.

I did the ignition recall myself. Fun drilling out the security bolts. Amazing the price disparity. Probably good idea to have a new switch on hand for the eventuality.

Fred, I'm confused. Does lubricant from the tumblers reach the contacts, or doesn't it? Or should I wait until Friday to ask ?

Not directly, but, you know, Gravity... it's not just a good idea, it's the Law!

Any stuff you spray from the top may works its way through whatever little crevices there are and foul things up.

That explains it then, it's Newton's fault. If he hadn't invented gravity we'd have been much better off.
