Full beam and left indicator stopped working

Stripped the bike down to do valve clearances, had the ecu mapped by wiz at the same time. Put it back together and the left front indicator doesn't flash, flashes fast on the display and the full beam doesn't work when switched on or by pressing the flash.. When the ignition is on but the bikes not started I can hear a high pitched noise that doesn't stop until the ignition is turned off. Any ideas why this has happened?

I know with some cars, the fuel pump can whine. But I've never noticed it on the Tenere. I don't know if the ECU remap would affect that. The "fast flash" is going to be caused by the absence of the non-working indicator in the circuit. That's how I always knew I had a blown bulb; fast flashing. To me, the indicator, and fail to full beam, is gonna be a lack of/loose connection. Being that you had the bike all torn apart and all.

Probably that sharp noise (as if it were high frequency, a buzz), is related to a voltaic microarc, in a resistive environment, which means that a spark or short circuit is not caused, but a microarc is. It is usually typical in electrical contactors with a bad contact. In the case of the S10, a contactor would be in this case a relay. Some electronic components (such as those inside the dash, inside the ecu, or inside an “led bulb”) can generate this buzzing noise while they are working. Transistors are the ones that commonly emit a buzzing noise.

First or second generation? There’s a recall for the headlight wiring on the Gen1 bikes. Don’t know if that also affects the indicators though.

I don't have the link, but yes there is. I found it last year and put my vin in the website. It told me mine had not been done.
Side note: I found it through a Google search.

I would see If someone has a gen1 bike near you who is willing to help you. I would swap out and try their ecu flashed or not does not matter as long as their lights work.

Whenever something goes wrong ask yourself what has changed and start there.

Hope this helps. :)

PS. If the lights work take up the matter with wiz. I believe you will have proven their responsibility for the trouble.

Anthony will be able to tell us if a ecu can effect lights. If it can’t then the short Theory becomes probable.

“Well I just took the ECU out of my buddy Chris's Tenere and put it in my Tenere and my headlights work just fine! Sooo that and all the other checks that I did tells me the my ECU is not putting out the necessary ground to close the relay to power my lights after the bike starts.
At least now I know... but it also tells me that I either get a new ECU or go around it and put either a switch to turn the lights on or a relay to turn the lights on (which is just an electronic switch).
However my dealer has sent a request for assistance (goodwill assistance) from Yamaha regarding my ECU.
I got the bike October 19, 2011 and have over 50,000 miles so it's not in warranty. :-/
He said he should hear back Monday afternoon possibly late. So I should know either Monday late or Tuesday.
I've also got a call out to a Yamaha Southeast District Sales Mgr.
Wish me luck.”

Got the above from this post informative. Our lights go threw the ecu. Think about it the headlight won’t come on till the bike is running. Pull up the post it’s long too long to copy it all.



No headlights... not the sub harness... ECU?!?!

Well my 2012 Super Tenere' while having been the bike of my dreams... just love this thing has perhaps taken a dump.
First of all I've got over 50,000 miles and this is the only real problem... yea I had to replace a battery just after the warranty went out (and no Yamaha wouldn't cover it) and I have had to put a second set of rear brake pads on and lots of tires (to be expected :) ). I also have replaced both H7 headlights... with ordinary H7's. Nothing else.

So here it is. I rode from my home in the foothills of the Blue Ridge Mountains of Western North Carolina (USA) to Orlando, Fl to work the AIMExpo a couple of weeks ago. On the ride down all on back roads I ended up getting there just after the sun set... my headlights were like non-existent as in I only had the running lights. Well I made it to my friends house. A quick check revealed that it was not a fuse and not the bulbs. I had no real way to work on it down there and we had no time to work on it as in the AM we had to get to the show. Worked the show for 5 days and during that time I did communicate with Greg as in "Greg the pole" aka The Tenerist about my "problem". Not having the bike with me at the show I was not really able to test some of Greg's suggestions to see if I did indeed have a cooked wiring sup harness. As I needed to get home I rode home on the interstate with no headlights just to be sure to get home before dark.

As I started to attempt to diagnose the problem I replaced the headlight relay... which didn't fix the problem... I ordered a new (updated Yamaha P/N) sub harness... which didn't fix the problem. So last night with some help from a friend who is a MC mechanic we traced it back to the ECU.... YES, the $817,17 ECU!!! :-[ It seems that the headlight relay gets it's ground from the ECU... well it's supposed to but my ECU doesn't seem to be providing this ground to activate the relay. we tested everything from the ECU to the bulbs and all is OK there.
So I need/want to do one thing that I didn't do last night... hook the ECU back up and the relay and plug in the headlights... start the bike and then provide the ground to the relay to see if all works that way. I feel strongly that it will work and that I'll still be left with an ECU that's not working properly.
NOW some additional questions:

1) no warranty... ::024::( only time in my life I'm thinking I should have gotten the extended waranty!) what's the chances that Yamaha will step up to make this right?

2) can the ECU be A) checked to see it all else is working properly? B) can the ECU be re flashed and thus fixed?

3) Can the ECU be fixed? (reprogrammed?)

Ok... once those questions are answered... I will most likely hook up another relay, likely through my FZ1 (fuse box) to provide the ground the headlights need after the bike starts to light the headlights and live with it.

I was planning a ride out to CA and to ride Baja, Mexico again in February... would you trust this bike with the fix around the ECU?

This sucks! :'( :'( :'( Damn, I wanna ride this bike... while at the AIMExpo I bought new Trax bags in black and Denali D2 lights for it too...

First you claim it’s first generation then later say it’s second generation which is it ?
As far as goodwill service from Yamaha on a reflashed ECU I would be very surprised to hear they covered any replacement cost, I think you should be talking to the outfit that reflashed it.

Where did I say it was a Gen2? My second message I said it was a gen1 and that's the only time I've mentioned it?? I wasn't expecting any yamaha good will and never said thats what I was hoping for, its a 11 year old bike. Not too sure what you've been reading because all of your points in your comment are wrong, maybe your were just having a bad day. All I wanted was to see if anyone else had experienced the same issue so they could give me some advice. However, thanks for your input.

You should start "trying to solve the problem", starting from the easiest to the most complicated, and ensuring that fuse "1" is operational.
1) check that both bulbs are good. Sometimes they just burn out.
2) check, after it starts, that you have "both feeds" (+ and -) in both lamp connectors.
3) if you don't have + or - on the connectors, then check the headlight main connector…
.4) then the same with the relay that is activated by the ecu “after start”. If the relay does not activate, it may be faulty or it may not be receiving the signal from the ecu due to a false contact on the pin, or an internal problem with the ecu..
.5) if the latter were the problem (which would be extremely rare) It is easy to solve as Fennellg said before, simply feed the lights relay or directly with an external switch and you will continue riding the motorcycle for several more years

My Yamaha dealer pulled the recall history on my bike when I brought it in to change out my front tire, a gen 1 bike, and the 2 known recalls had been done on it. Your dealership should be able to pull this easily for you.
