I don't think I've ever hear of someone in here with an ECU that failed.
Have you had that verified or is it a hunch?
Well been following the service manual and think I have done every thing they asked up to this point. I have checked all the fuses, verified power and ground to the modules, have pinged the earth and power circuits for continuity. Also checked continuity on the two CAN circuits from front to back and between all the modules. Not sure what else I can do to rule other things out?
I have yet to find a way to test the ECU

Maybe you could send it to someone on here and they could swap it out with their ECU and see if their Motorcycle operates. That would prove if your ECU is good or bad.
just an idea..

This might be one of those times where taking it to the shop and having the ECU tested would be worth the expense. I wouldn't want to invest in a new one until it was conclusively shown that the module itself was bad. It may be possible to remove it and have it bench tested, so you don't have to tow the bike to the shop. It might be worth a phone call to a shop and ask them what they can do.

I know the US models don't have quite the same security setup as EUR (and CDN?)... but even so, can you just "swap out" (with a buddy) ECUs on these bikes?
I guess I dont know for sure. Certainly you can buy the ECU from any dealer and they will ship it to you, my assumption is that it is pre-flashed at the factory. I checked models from 2014-2018, basically any year that had ES suspension and they all have the same part number, are they the same calibration I dont know. I guess it is possible you install the new ECU and then the dealer has to use the Yamaha factory diag tool to flash the right calibration. Be nice to get someone to chime in who is a yamaha tech or works at a dealer.
The service manual that you read is the same one that the official Yamaha mechanics read...if you don't read "reflash" in the manual...the official mechanics don't read it either...it only reads "change ecu"... that is, the software is already preloaded from the factory
What year is your S10?….and what year is the SS manual that you read?
I don’t see a problem switching ECU’s for a test. As stated, the ECU’s are loaded with software pre production. It’s generic. That is one reason why a flash/tune can give you extra power.

Ok, so I have gathered that you own an ES model somewhere between a 2014 and 2018. Would you care to elaborate on exactly what happened to lead you to conclude that you have a fried ECU?

I’ve swapped out ECUs between other bikes of the same model, even different year models, without issues. Any forum members live close by? The ECUs come preprogrammed from the factory. I’ve never heard of a dealer having to do that upon set up.

If the failure of The communication is in the CAN network….one way to know if the network is ok….is to measure the resistance between the two digital signals….it should give you 120ohms…..if there is no resistance….the network is open. Usually the network is closed at one point and at that point there is a 120ohm resistor…..when the network is open (no resistance), the scanner can't read the ecu
120 ohms for CAN HIGH (engine, transmission, etc)
100 ohms for CAN LOW ( AA/ligths/electric seats/radio/etc)
S10, do not have a Low network

Man, you start following a thread like this and you begin to really realize how much you don't know....
ECU for sale
I purchased this so I could keep my bike on the road while I sent my original unit off to be flashed. It is off a 2016 Gen 2. My bike has be updated and I no longer need this spare. If you are thinking of getting you ECU Flashed, you can do the same and not lose out on some spring riding. $200...

Maybe, you should put all the posts together….to have a global vision of the problem…..problem that I think started with the previous owner and a failed start attempt due to a dead battery……with many posts, they all seem different problems…..
Anthony should be able to tell pretty quick if the ECU is dead and you can contact him at: https://yamahasupertenere.com/index.php?threads/a-more-affordable-flash-option.10252/
My guess is in the connections leading to the ECU, but this is a best guess based in how fragmented and little we know.
