FI C31 code
This is just for general information.
I was on a long trip a few weeks ago and kept getting an intermittent FI warning light. In a rest area I McGuyvered a couple wires onto the Dealer connection and after a few tries got a C31 code.
That night in a motel parking lot I found the fault to be on the clutch safety switch which was loose. This bike is a K5 650 with better than 100 K miles: a trusty old warhorse.
Yes, I do travel with a laptop that has the repair manual on it, so finding the fault was not too difficult.
I just disconnected the connector, made a small jumper and connected the leads, taped it all up and kept on keeping on...
Perhaps I'll replace it someday, perhaps I won't, but no more FI light for that issue.
