Error 39

[arabian2]

Just when I thought things were looking up. Now I have an issue with my Gen2. Any way does anyone know or have seen error 39 and how to resolve it? Only thing I get is 39 where the mileage usually is, and the check engine light on. Will not crank over. TIA

39 - Open circuit detected in a primary injector.

I do not know if this is for the VMax but this is the code description for the R1 and R6. I dont see why Yamaha would have a bunch of different codes for different bikes. But anything is possible and dont rule it out.

Sounds like I have to take it to the dealership then. Dang I can't catch a break.

After looking at the link and noticed one of the suggested things to look at was the ECU. I changed out to my original ECU and bingo, the error went away. I put the Flashed one back in and the error came back. I will now button it up partially and see if it turns over. Even if it does I don't know if I can ride it as I don't know what caused the bike to work one day and the next (without warning) nothing. Don't want to mess up both ECU's if the root cause is something else. Anyways I will wait a bit to see if I can ship my ECU back to Mr. Nash when he is feeling better to see if in fact the ECU is crap or if there is a hic-up in it and needs to be reflashed.

does not sound like software error. Perhaps just a bad/dirty pin on the flashed ECU connecting terminals, visual check is easy even at first without knowing which pin is related to error 39/open circuit primary injector.
