F1 Light Fix

I had the F1 light on for around one year, it reported code C-28, which is the STVA servo motor. I'm not good at troubleshooting electrical problems so I thought I needed a STVA and the dealer was happy to give me one until they told me how much:mad: $1000 dollars just for the part. So I gave it the old college try and I found that the ECU must sent and receive a signal from and to the STVA. So while I was checking the wires to the ECU from the STVA, which checked good, I put everything back together and then check if I had an error code. Well I had two codes now C-28 and C-23, so I grabed the connectors and did the shake test and to my surprise the light went out and code c-00 was reported.:bigthumbsup: So I proceeded to take the Orange plastic piece off each ECU connector to reveal the metal contacts and sprayed them with electrical contact cleaner and also the ECU contacts, reassembled everything making sure they snapped in and I have had no F1 light for two weeks, bike is running great.:D I would try this same repair before you take it in to the dealer. Good Luck:doorag:
