      When I brake hard, the FI warning light comes on for a moment and then goes out. The engine is operating normally.

      I have vetified with the diagnostic tool and the dashboard displays the code “C” without numbers behind. Does this mean “no defaults”? How should this be interfered with?

      Thank you for your information.

      Hey!

      You may have hit the nail on this one ,  as indeed  *C* without digits doesnt seem to indicate any actual fault.

      You may ride as usual but just keep a good eye on all parts to ensure nothing rattled loose under braking?

      Dare I say though,  what if you checked your brake switches arent loose or attacked by weather?(rusty contacts). Hopefully thats not whats causing them to act funny under a full brake  (where bike even shifts its weight to brake force)

      If this was a different brand, i would have guessed it was something to do with an ABS system and ECU talking to each other (something’s a bit off but not to panic yet?)

      As for Hyosung usually the ECU will tell the exact code  (eg. D45) if some device is failing or acting intermittent.

      But i hope this bit of reply helps & hopefully its just nothing really👍

      But update us if something changes or If i missed something.

      You may also disconnect battery for few hours or overnight max. It may or may not force the  ECU to reset the C code. (There isnt a lot of research data ive collected yet on GV650 EFi/Ei’s to see how effective this is. So you may try)

      OK Marcel, thanks for the reply. I will go for a ride when the weather will allow and see if the FI warning goes on. If so, I will disconnect the battery for reinitialising of the ECU. I will inform you what will happen.

      I have disconnected the battery for a whole night, and I got no messages “FI” since ( I rode about 60 kms). I hope it will last.  🙂

      Thanks Marcel
