FI light illuminated

[Riverrat]

I have an 06 comf/nav with a 103K miles on it. I was riding the other day and noticed that the FI light was ilumminated. I go to my destination and set put the center stand down and received on long flash followed by two short flashes of the FI light. This repeated at least eight times so I just shut it down. Could I assume this was an abnomally or do you think there is more to it. The bike has been running fine since. Other than that the machine has run flawlessly with zero issues. TIA

I believe you have just been sent a code. Code was most likely 12. And, if I am correct (may not be), that is the code for an O2 sensor. I would suggest that at your "convenience" you take the bike to a qualified Honda dealership, or Honda repair shop, that can connect their shop tester to your bike, pull any and all codes, and see if there are any other codes that appear. It is normal that if one code is flashed, they "may" be other codes in hiding, and only the predominent one will be flashed. A good dealer may suggest to pull the codes....then "wipe" the codes from the system, then ride the bike again, and see if any codes come back. If any do come back, that is usually the one item that needs to be fixed.

Now, if someone with the Electronics Service Manual can find the list of codes, and confirm what a code 12 is, that would be helpful.

With 103K miles on your bike (good riding on your part), it would be acceptable that an O2 sensor would need to be replaced.

Found this. GL1800 FI "Fault Indicator" Dashboard Codes
If FI (Fault Indicator) light comes on pull over but DO NOT shut bike off. Put in neutral and put side stand down, RPM’s below 1500. This signals the ECM to send the error code to the FI light. Count the number of long and short flashes. This will give you the error code.
If you shut the bike off the error code is lost - sort of. It will be retained in the ECM but it is harder to get out. If the bike stops and the will not restart you can get the FI light to flash the error code by cranking the engine for 10 seconds. The FI light will then flash the error code.
Long Blink = 10 Short Blink = 1 i.e. long long long short short short = 33 check error code 33

Code 12 would be the injectors... check your connections.
