I would not take what scout says to heart to much.... he has a tendency for stating things completely incorrect, misconstruing things and outright being confused about what the subject matter is.
So correct me if I am wrong but you are saying that with the front wheel not spinning but the rear wheel spinning you are not getting a mph reading? If so that would be correct if your connector is contacting the sensor correctly. Basically the bike is reading no movement from the front and no movement from the rear so there are no issues. Its when you move the front wheel without any reading from the rear or vice versa there are issues with the KIBS or KRTC. Now is the connector in the image above from the wheel speed sensor? Or from the harness side?
Np for the welcome, when you have a moment make a thread introducing yourself. Makes for some good rib jabbing if not good place to see the bike.
ok so I have my bike on a rear stand during all of this, I believe the rear wheel sensor is the only one that reads for speed and mileage on the speedo while the front is for sync purposes (KIBS/KRTC). Reason I say this is because everytime I've clean my chain I have it on this stand and it has read speed on the speedo (rear wheel moving/front wheel stationary).
I have only gotten the KRTC 123 FI error just once (missed the code), and that was when I was on the road after realizing that my speedo wasnt working. (I had just finished re-assembling my bike and did not test every nook and cranny, rookie mistake I know, as it can be dangerous)
At the moment, while my bike is on the rear stand and the rear sensor being disconnected, I can turn it on and put it in first and let it spin the rear wheel (on 1st gear Idle RPM runs about 8-10mph). I would have thought by now that the KRTC FI error would pop on... or at least a b code showing that my rear sensor is missing but nope. I just have a speedo that sets on 0.
Now, what I have in the picture is the Male connector thats on the rear wheel sensor which I thought was split on 1 pin but it was just my eyes playing tricks on me (didnt sleep the whole night trying to figure out the problem), the Female (harness) connector is all good. I came to the possible conclusion that my rear wheel sensor actually just failed because of a couple of reasons
1. The insulated wire that is between the actual sensor and the male connector was somehow pinched between the muffler and swingarm, giving 2 possibilities:
1a. The wire couldve been nicked. (Multimeter test shows its a closed circuit, but im still skeptical)
1b. The wire couldve been heated to the point that it somehow messed up the magnet on the sensor... even tho there is no warping or visible damaged on the outer wire.... (heat + magnet= failure).
2. After finding out the front and rear sensor uses the same connectors, I swapped the front to the rear and I was finally getting speed readings on my speedo. This cleared my mind of the harness/ECU/KIBS system being the problem. I did not try the rear sensor on the front tho, mainly because I thought it'd be pointless since I couldn't directly test it as well when it is connected to the front and I have no way to get the KRTC error to come up reliably.
So... I guess what I am trying to find out right now is
-Why the KRTC error wont show without the sensor being connected
-How common is a failing speedo? What is usually the culprit?
I do find it odd that the rear speedo failed when my last impact was on the left side of the bike ( I high sided on a right turn and the bike slammed on its left side into grass)
I made a topic, look for it.... made me nuts for a while..
no codes.. and the speedo was jumping... cero, numbers, then cero... on drugs the speedo..
Yeah I just read through that whole thread, did it finally go away? and Im not having the same problem, my speedo just stays at 0 the whole time and KRTC does not engage in any level no matter how hard I slip the rear wheel
