Dreaded Fi Light

Hi guys,appologies if im reinveting the wheel but I have an issue with the Fi light constantly on,from the time i turn the key on it stays light!The speedo was not working so i had the speed sensor replaced.Ive jumped the DLC and the light will not flash at all it just stays lit and would like to resolve it.I have searched and read other threads and my thinking is i need to erase the error code from the ecm but that just wont work.The bike runs well.

Bike:Cbr 600RR 2003 with Yoshi slipon.

Thanks in advance guys

Maybe this would solve it:

Exhaust changes may be triggering bad reads. Good Luck. (:

hi guys, I see there's a few with this problem recently so I've been going through my haynes manual. I don't know if any of this info will help but it's worth a try.

so according to this book, if the red MIL & FI lights are on while the bike's running then a fault has occured in the FI system. The ECM will store the fault code & through a series of flashes can be read.

Now for the guys with the solid FI light, the book says:

# of flashes = zero - no code (warning light stays constantly on) - engine runs normally - possible causes are: (1) short circuit in data link connector or wiring or (2) faulty ECM

my book tells me all the flash codes so if you do get flashes let me know & I'll try to tell you what it is. also this book is based on a stock bike so I have no idea how aftermarket parts will affect these codes, but a proper honda dealer should be able to run a full diagnostic

hope this helps in some way

OR shoichiro honda's suggestion could be the answer

Check out the data link connector under the seat and its wires, connections are touching somewhere if not replace the ecm

If there are no codes, you could try resetting the ecm.

FALSE... The bike would run but ecm would have internal issues. I would try swapping with a known good ecm to see if the light goes away.

I've done a visual inspection but have not seen any vacuum pipes unplugged etc...maybe it could be a short circuit in the DLC but how will i know that?

I'm having the same problem when jumping them, yesterday I went through all the connectors and put electric grease in all of them including the ground and had no luck. I ended up unplugging the battery and let it sit over night. I'm going to try again tonight.

Why are you guys trying to jump connections this is the reason a short is occurring in the dlc which makes your FI light remain on....

Reseting the ecm is to clear any codes but your light is constant with no codes... Get a multimeter your green wire is ground ck for continuity to chasis ground. Do the same cks for other wires

Tried fixing it again tonight I got a multimeter and checked the dlc and there no power to it over a volt. I checked all the wires and checked the front dash wires as well.

Which wires do I jump to get the code and or which ones do I check with the multimeter

IMHO, download a copy of the service manual. All the electrical troubleshooting is in there and it walks you through it. It will be much easier than playing the guessing game with a bunch of strangers that aren't looking at you bike. I'm always paranoid about electrical crap so I always consult my service manual before the forum. The last thing you want to do is make things worse by frying a sensor or some sh!t

No volt cks. Were looking for a short, a unwanted path to ground set meter on ohms one lead on neg batt one lead on green wire it should read around 0.001. Do the same cks to other 3 wires they should read OL
