Yeah, KiPass has become such a big thing that I think some people believe it controls the phases of the moon :-) KiPass's job is to authenticate a valid fob and ALLOW the starting sequence to BEGIN and that is all. The chain of events is that the KiPass ECU sends an 'okdokey' to the main ECU and then KiPass is done with the entire bike save the display unit. Even if you leave the fob on the ground when you started the bike and drove away the only thing that can happen, while the bike is running, is that the display will display 'Transponder Error'.
The reason for all of this is simple: common sense and liability. It would be disastrous to have any part of the bike stop the engine for any reason on its own without the operator's involvement. I mean, what if our bikes simply stopped running in the middle of a long curve, well leaned over, because the temperature was too high as judged by the ECU? No one would make a vehicle like that, including Kawasaki. KiPass (or anything else on the bike such as low fuel, too high a temperature, no oil, etc.) cannot stop the bike. The worst case scenario is no oil pressure which will result at some point in an engine seizure but again, that fault will NOT stop a running bike, only alert the rider; it is up to the rider to stop the bike when safe to do so.
I really do believe Chris's problem (Burbs) has nothing to do with KiPass but rather is a simple electrical fault, given his description (starting with the bike stalled....). The message 'Transponder Error' was just one more of the symptoms of the underlying and basic problem, which I believe is a central electrical fault and most probably a simple one at that.

Once again I learn something from Brian. I did not realize that kipass could not affect the bike when it is running - good to know if I ever run into a similar situation.
