Yesterday on the morning commute, I got a KTRC Error on the dash. Suspected that it might have something to do with the left side leaking fork seal somehow getting fork oil on the sensor. Spent the day looking around on the forums and found everything from a broken cable coming from the sensor to dirty connectors on the ECU (mine's never been pulled).
Checked before leaving work and felt no fork oil on the sensor (the piece attached to the wheel, not the wired component). Cable looked fine. Didn't reseat the ECU connections figuring I'd get to it this weekend, if need be.
Of course, the error has NOT reappeared since.
Any idea what may have caused it? What triggers this error?
I believe a KTRC error is when the traction system senses a differential between the front and rear wheels. Because the sensors are the ABS wheel disc sensing system, you may well be right about oil causing a problem but I sort of doubt it because it is an induction system and should be impervious to oil; exactly how the cam and crank position sensors work perfectly in an oil- bathed environment. Any chance it happened during acceleration? If so, maybe the rear wheel broke traction slightly and turned a but more than the front wheel; it does not take much of a difference to trip the ABS or traction control systems.
I'd read that thread previously, but rereading it now seems to make more sense. Going to try several things before looking at replacing parts. Error cleared itself during lunch ride.
Will start with cleaning rotational sensors and checking clearances on the hall effect sensors. Will clean and reseat ECU connections as well. If it reappears, I'll run the tests on the sensors specified in the manual.
Start ALL electrical diagnostics on this bike by checking / redoing ground and battery connections. Steve
Occasionally a sensor has been far enough away from the activation disc (the one with the holes in it) that it cannot sense the metal in- between the holes. That may be your problem.
Also, check both wheel sensor connectors to make sure they are clean and do not have any corrosion in them; Japanese sealed connectors are excellent but if one is missing a seal, for example, water may have entered the connector and caused some corrosion. And of course make sure the connectors are fully engaged by hearing them 'click' and lock into position.
It is possible you have a faulty sensor but that is going to be somewhat difficult to diagnose if it is intermittent, which your problem certainly is.
I would start with the sensor / wheel spacing and alignment, and then check the connectors on each sensor.

Do you have a factory manual?
