ECU Code 19

[windchaser1942]

I did a tour this past weekend of 545 miles leaving my home in southern WV for Princeton, WV. I got on the superslab and ran down to Fancy Gap, VA and picked up the Blue Ridge Parkway. I ran the Parkway until dark stopping at Boone NC for the night. Sunday AM I took off for Johnson City, TN on Hwy 321 picking up IH 26, then HWY 23 and finally 119 which brought me back home. The bike ran just great. This morning when I went out to take the bike to work it would not start. Then I am thinking.. "did a dodge a bullet or what"? The motor would turn over but not fire. I just happen to turn the key off and then try it again.....bingo it starts. I am not accustom to watching the LCD screen for error codes but just happen to see a 19 where the Trip 1 odometer is located. Jumping on the net I went looking for what that meant. Apparently Yamaha has had some problems with ECU's and fixed them under a recall. The problem only occurs "over 3,000 ft elev". I live at 1500 ft; my travels as outlined above took me to right at 4500 ft. My overnight in Boone NC was at 3266. My trip home kept me close to that number all the way. The bike was started from a cold start while in Boone. Although it was stopped and restarted 3 more times prior to getting home it never cooled off until being parked overnight. Has anyone had this problem? Would the cold restart above 3200 feet and no real subsequent "cool down" during the days run have kept the ECU from resetting to the lower elevation? I figure if anybody knows the answer to this it will be on this forum. I'd call my dealer but they are closed today.

You are not describing the gen 2 "Altitude sickness", and it doesn't throw an error 19 anyway. Not sure what does, but someone will chime in soon. The ECU recall will not effect your cold starts.

try a GOOGLE search using ECU code site : fjrforum and you'll find all the fault codes listed. Amazing what a search can do !

Looking at the manual, error code 19 is described as: Open circuit is detected in the input line from the sidestand switch to the ECU.

Definitely, this would keep the bike from starting.

Did you try flipping your sidestand up and down & up b4 trying to restart it? If not, you might try it. That's only a temporary fix, though.

Also, if that doesn't work try starting the bike while it is in neutral.

There is a tech procedure around here somewhere that tells you how to clean this circuit so this does not continue to happen.

Not a tech... just a been there, done that kinda' person,

thanks for the reply. I did that and what I wrote was after reading what I found on the net.

Thanks for your reply. Not having a manual I wasn't able to detect what the source of terminal four was although it was mentioned in the research but noting more. I really appreciate your response. The side stand was up and the bike was in neutral. The bike turned over several times but would not fire. It was only after turning the ignition completely off and then turning it back on that it finally fired. Since that time I have restarted the bike several times with out a problem. Thanks again I guess it is time to buy a manual. Know a good source?

If you did my search you would have come up with a complete list of error codes shown on the second topic ! I bet you weren't using GOOGLE for your search engine as described.... This is by far the best way to search this site as the Search function on this site isn't very good....Try it, you'll like it....Just trying to help, no offense meant . .

Get the ECU replaced with the updated one if it has not been done, even though it's not the problem this time - It's free anyway !

 

[luvtoride]

So good, you got it started. You might want to address this problem at some point because it will happen again & may not restart so easily.

A good source for the tech manual is through Yamaha. Not sure if 3rd party vendors offer it up. If you buy from certain sources, it is surely copywrited material. From what is said by others on this site... you bought a $13,000 motorcycle... go ahead & spend the $50.00 for a legal tech manual.

I am pretty sure that the "new members" section has some info on this subject.

Good luck with the bike, Heidi

When my bike cranks, but doesn't start, sometimes it'll throw a code 19 if I crank it long enough, but I don't crank it for very long anymore since I've traced it to the ignition switch being intermittent with the side stand switch being fine.

If I cycle the key off then on, I've been good to go so far.

 

[Geezer]

Well, I don't have an '06, but just from reading this forum I can say that there have been a lot more ignition switch failure than side stand switch failures on the '06 model. You may want to look at the ignition switch threads and see what others have done to remedy that problem so that you can be prepared.

 

[luvtoride]

Correct me if I'm wrong... but what does the ignition switch have to do w/ a code 19? Are these possibly a coincidence? Does the ECU throw off faulty codes? Perhaps we should beat Yamaha about the head & neck if that is the case.

"what does the ignition switch have to do w/ a code 19?"

If you trace out the wiring schematic (at least on a gen I bike) you'll see that all the safety interlock switches, kickstand included, ultimately make their way back to the ECU via a set of contacts in the ignition switch.

This happened to me once, though I didn't notice ant error codes (didn't look either). The only thing I did out of the ordinary was that I'd left the ignition switch in the "on" position for several minutes before trying to start. Turned over but no fire. Switched it off, waited a few seconds, switched it back on and it fired right up. No problems since.

So, you are saying that the ECU is throwing out faulty codes?

The code is correct for what the ECU is seeing. When the software engineer was writing the code he/she never took in consideration that a key switch failure could be causing incorrect voltage levels at the Starter Cut Off Relay (SCOR). The programmer only wrote the code so that when 'conditions are like this', AND there is low voltage at the SCOR it can only mean the kickstand switch is defective.

As we are finding out, Code 19 may indeed be a kickstand switch problem but on Gen IIs it may also be an early warning signal for a failing ignition switch. In this case it would be pointing to the white plastic ignition switch piece with the spring loaded contacts being distorted by heat.

"Starter Cut Off Relay"

Oh, if only that would happen on a fault condition...., instead of happily cranking away causing the user to think of all things evil.

Yamaha's misnomer words from the Gen I FSM. They made a minor correction in the Gen II FSM and now simply call the whole assembly "Relay Unit".

Follow-up...

I took my bike to the dealer today and related the above story. In short, the problem "does lie with the ECU" and the pressure sensor within it. The problem is covered under a re-call for certain bikes with specified "vin numbers". Sorry I can't say what the range is as I did not get that. The dealer is a major seller of FJR's in the area. The Cycle Shop located in Huntington WV. The problem appears when you ride above 3,000 feet. The owner of the dealership is an advid FJR rider has had a similar problem while out in Colorado. The fix is covered by Yamaha.

In short...thanks to all who provided comments on this problem. Hopefully, what I have posted may be of assistance to others.
