I have a 2007 FZ6 S2, weirdly my bike seems to be running fine, but while riding around town (30mph, around 4k rpm and a lot of stop and go) after about 20-25min my check engine light comes on.
I checked the error codes by going into diagnostics mode and error 46 comes up. The service manual says "Symptom: Power supply to the FI system is not normal. Probable cause of malfunction: Malfunction in CHARGING SYSTEM."
I checked the battery and it seems to be fine, with the engine turned off it shows around 13.5v, when I start the engine it drops to around 12v and then it comes back up and when accelerating it goes up to around 14.5v
I checked the stator coil resistance and it's withing the specified range 0,23 - 0.32 Ohm
I replaced the fuse for the FI system and also cleaned all of the other fuses.
I don't know what else I could check, anyone else encountered something like this? I googled this error but all the info I found doesn't really apply to me since my bike seems to be running fine.

I went to a shop this morning to talk to someone there about another problem I'm having and one of the guys mentioned that when I turned the ignition on the temp display said High but the fan didn't start working. So my question is, since I can't seem to find this info in the service/owner's manual, when does the fan exactly kick in?
