    Default FI Light

    FI light is on, but bike will run. Drained old gas, ran new gas with SeaFoam through for a while and have tried the battery disconnect to see if it will re-set. FI light continues to come on at start up. Oh yeah, also replaced the fuel filter today to also try to clear up the FI light. Any help/thoughts appreciated.

    Mine came on for no reason this morning...after disconnecting battery, checking connectors, it still still stayed on...I finally checked the cam on the servo motor, and the bolt came loosened and caused the cam to not be able to turn during the initiation when first turning the key on...I have aftermarket exhaust and was using the cam to eliminate having to pull pin for fi light. I put some thread locktite on bolt tightened it back on and problem fixed. God luck, hopefully it is something simple!

    I went riding with Seapup the other day and his was on for that very reason. He had not ridden it for a while.

    Default F1 Light - New problem

    Okay, did the code check. With the "special tool" in place, comes up C00 - no issues and bike starts with no F1 light. Take the special tool out, F1 light comes on. Any thoughts?

    Disconnect battery for 20 mins. It should go away. That will act as a reset.

    Default Next F1 Issue

    Okay, disconnected the battery for 30 minutes. Still get the F1 light. Put the special tool in and still get C00 code on the odo. As long as the special tool is in, the F1 light stays off. I can even pull the tool out after start up and the light stays off, but if I shut the bike off and then try to restart without the tool in the ECU plug, the F1 light comes back on.....AAAAAGGGGGHHHHHHH!

    Are you allowing the bike to go through it's start up procedure, before starting? C-00= No Code.

    Yup. Let the speedo cycle all the way and wait for all the valves/etc to stop making noise. Only then do I hit the run switch, which is when I can hear (fuel pump?) cycle and that is when the F1 light comes on.

    Do you have original exhaust on bike?

    Nevermind... I see you are. Is bike still under warranty? Again, C-00, is No code. I don't know why it is coming on, if there is no code. You may want to try pulling the wire out of th ecu, to see if it is being caused by the SET.

    By wire, do mean the "special tool" or is there some other wire?

    I'm pulling the C61 code. Pair valve solenoid. I removed the tank and air box to make sure I capped everything off and reset my battery for 8 hours! The FI light still comes up. I'm running cobra slashdowns, Holley intake with k and n filters and a PCIII. Any ideas on how to turn this light off?

    What did the trick? Unfortunately I can't access the link above and I'm having the same problem of FI red light is on all the time on 2006 M109R.

    You're not going to get an answer. The guy you quoted hasn't been on this site since 2010.

    Remove the left side cover, start the bike and if the FI light is on then place a jumper wire across 2 specific terminals in the white electrical connnector that sits just above the ECU. It probably has a black rubber cap on it.

    Once you jump out this electrical connector a C-xx code will appear in your odometer.
    This code will tell you to why the FI light is on.

    Here is a link for a youtube video that shows you how its done. Note which 2 terminals are jumped out in the video.
    The bike in the video is not a M109R so the electrical connector on this bike in a different location, but the video will show you how its done.

    https://www.youtube.com/watch?v=SeeNrhRUtcU

    Here is a list of possible fault codes

    C23: Tip-over sensor (TOS)
    C24: Ignition signal #1 (IG coil #1.1) - For Rear cylinder
    C25: Ignition signal #2 (IG coil #2.1) - For Front cylinder
    C26: Ignition signal #1 (IG coil #1.2) - For Rear cylinder
    C27: Ignition signal #2 (IG coil #2.2) - For Front cylinder
    C28: Secondary throttle valve actuator (STVA)
    C29: Secondary throttle position sensor (STPS) - (Note *2)
    C31: Gear position signal (GP switch)

    Updated the next morning: I have: C46: Exhaust control valve actuator (EXCVA)
    Is there a fix for that?

    Update: I fond Service Bulletin that explains how to remove Number 62 wire from the engine ECU.
    I've already done it and the Error Code C-46 went away. I'm a happy camper now!
    Thank you very much for your help!
    Mike.

    I hate to annoy you guys and I know that my question is unrelated to this topic.
    But I own M109R for three days now and already am missing the things that I use to have on my Gold Wing.
    I do realize that there is nothing I can do about comfort and cruise control, and what not, but what I am missing the most are the saddlebags and the rear trunk.
    I started looking, over the Internet and noticed that there are so many different options... I realized that I should better ask someone who knows.
    Could you guys recommend good quality hard (I don't want soft because they sag after a while) boxes that work best for M109R?
    Here is my bike:
