650Nk Error codes

**Wald0** · 07-11-2013, 01:52 AM

So i have been getting this 15 short flashes for while from EFI but i did found out that it could be just service reminder
but manual don't know to tell that even, but yesterday i did turn electrics on and after that pulled full throttle (Engine off) and got new error code?? it only shows if i pull full throttle. so if i just start bike normally it don't give that code.

This time manual do knows it, one long and 2 short flashes= ERROR_INJ1(1cylinder injector)_SCG but i have hardtime to understand what does S.C.G = Short Circuit to Ground means?? :) there are 2 wires going to ECU from injector so does that mean one of those wires is broken and has short circuit?

And i know i should take it to dealers but as i like to fix everything by my self if i can i want to delay that little ( don't have time now to take it anyway) and if i take it i want already know something about this problem

G'day Mate, just so happens that I had exactly the same problem 15 short flashes and it turned out to be a loose connection on the injector assembly(fixed by a jiggle of the wire's) must be a small design flaw. Happy biking :)

did you have to reset that code some way after that? i did try to jiggle those wires but it did not help, maybe later will remove tank and take a better look of those injector connections

I'm talking to the Mec tomorrow so I'll look into it in depth for you, in the mean time your bike should still be ok to ride.

So decided to make drive dealers place to ask about those code's.. and while i was there radiator started to leak again!! talk about bad luck! but now the bike is there for few days more while they check it.. and they also will check if it was bought from their shop and has a guarantee still.. fingers cross

but i would not hold my breath too long

not a 650NK but I used to get engine warming codes when I hit bumps on my previous bike turned out it was a loose battery cable perhaps it is caused from the vibration coming off the throttle so fast.
