FI red light

lifeisnow · 07-13-2008, 8:54 AM

Hi there, when exiting my garage this morning I saw that the fi light remained on but the bike was running fine. I tirned off the bike and on again and light went off. It did not went on again, is this something to worry about?

I think that when the ignition is turned on the red light goes on. Fire her up, red light goes off. The red light should not be one when riding.

exactly but this morning it stayed on untill I turned off the bike, when I fired her up again the light went off. it only did it once so there is nothing mush I should check I guess

Use the search function for FI light fix. There is a whole thread on what to check and fix (if necessary).

Might have just started the engine too fast/soon. It takes just a few seconds for the bike to power up the electronics and do a quick self test as well as prime the fuel system. If there is nothing to fix/correct, then next time just wait the exta couple of seconds before pressing the start button.

lifeisnow · 07-14-2008, 2:04 AM

yes growler probably that is what happened, thanks mate

Growler67 · 07-14-2008, 5:05 AM

Skipping through too fast may have caused an error code. Just a guess. Keep an eye on it for any "blinking" and get any flashing error codes identified. Otherwise, I think you'll be fine

fi light on again, I hate it

Check out Section 5 page 8 of the service manual this describes the diagnostic check procedure and what the indicator light means.

If you dont have the service manual here is the link

My FI light, on my 2000 XX, started flickering last fall, but ran fine. Up until a couple weeks ago my FI light was fine, comes on for a couple seconds when ignition is turned, then goes, and I start the bike. 2 weeks ago the light came on and stayed on, would run for a short time then miss, stumble and backfire, sometimes quit running. It would start again, but same events followed.
It is in my local shop and NO error codes come up.?? They are trying to call AMH tech to see what to do from here. We suspect they'll say it is the ECM, an $8??.?? toy.
Since I am brand new here, is there a thread on the forum that may have some answers? I'd sure like to ride some more this summer without dropping a ton money.
Is ther anyone in Twin Cities, Mn. area that would let me plug in thier ECM?? I know, a long shot..

Thx,

Ominousone, there is indeed an important post on this, it's actually the one mentioned earlier in this thread:

1999-2000 Honda CBR 1100XX FI Light Fix

That will take care of the most common reason for the light to show up.
If returns after that, then likely something else is wrong, but at least it should be able to then correctly give you a fault code to follow (as it unfortunately has in my case!)

I searched and found the fix and went through it and found my connector was clean. Rewrapped to make sure it stayed that way. But my light came back on, did some more searching and found out that one of the members checked the connections at the computer. On the 2K's it's in the tail section I removed and reseated the plugs on the box and the light hasn't come back on.

ominousone · 07-27-2008, 10:51 AM

Thanks guys, I did run across that thread. I printed it out and brought to my dealer. They did get ahold of Honda Tech and indeed were told that it is likely the ECM.... Honda Town, my dealership, will look over the FI Light fix before I drop the big money.

I would think that if there was a recall, Honda should have thought to recommend that fix before replacing the ECM.

Oh well, we'll see what happens and I'll report back.

Thx,
ominousone

ominousone · 07-28-2008, 9:40 PM

Update......It worked..... Just picked up the bike from Honda Town. No FI light and runs perfect again. I can't believe Am Honda Tech didn't seem to know anything about this.
Thanks all,
ominousone

Good to hear
Now next time save the coin and do it yourself then you can take that service charge and labor and go buy something for you

paulj · 08-02-2008, 8:20 AM

I have noticed that when i get on the throttle hard 6500rpm it will come on. In flight I will turn the bike off and back on light goes out. This is a weird issue and nobody here (va,USA) knows what to do. I really think that for us that are not so MR. Fix it...a little passion in explaining some of these issues like we are 4th graders... THANx

Check the link here for FI light it will walk you through the proceedure to fix the connector or at least check it. It is located on the left side on the 2K version. It will look like a lump in the harnesss line where the tape is wound around it. It is pretty easy to see the difference, you will need to cut back the tape to get to it. Be careful there are other wires in there. If you cut the tape wrapping on the flat section of the harness you will be working against the side of the connector housing where no wires are located. You will find a green connector with 19 wires coming in one side and a plastic plug sealing up the other side. Free this cap and look for corrosion. The hardest thing is getting the slack in the harness to get at it and be able to open it up. Just be patient and you can get to it.
The second place is at the cpu itself, on the 2k it's in the tail section under the seat in front of the tail light check these connections too.
Another neat little do it yourself item, in the turn signal bundle for the rear signals is a 3 pin female connector. Check the tech manual in the link here it will show you how to jumper that connector and get any trouble codes to help you locate any other issues that may be causing your intermittent shut down.
A lot of folks get scared when you mention computer control on a vehicle but the Honda guys made it pretty easy to find the trouble yourself with the manual and a little patience. You also have the board here to ask for help the minds of many can really help and your almost guarenteed that someone has had a similar problem and found the fix or at the very least you can share ideas and figure it out.
Open a new post with your issues and see what happens nothing to loose.

Does anyone know if the wire harness / test plug problem can cause an ECU failure. After limping approx. 120mi. home with compounding failures and antics associated with the test plug corrosion I have completed the test plug elimination to no avail. The bike will not start due to the fuel pump relay not energizing. During the ride from hell I had to bypass the relay to get home. Now after the plug repair the ECU shows a marginal circuit completion to the fuel pump relay (not enough current to pull in the relay). The bike will start and run with the relay bypassed. All connections have been checked, cleaned and found to be in good order. The bike is a low mileage, garage kept, '99 that showed no symptoms of the test plug corrosion nor any problems prior to the fialure. I have two '99 Blackbirds so I can swap the ECU from the other but I am reluctant to do so unless I can be sure the harness has not failed the original ECU. Any help would be appreciated.

Mr. Mike.

I am thinking that as long and you have verified there are no shorted connections that would cause a driver overload. I would feel safe swapping ECU's. All of the steps you have done would make me feel safe about it. It sounds like you have already did a code check with no issues. The only thing you might want to do is disconect the regulator circuit.

mrhemi · 09-01-2008, 7:12 AM

Beestoys, I performed all tests twice, both with and without the regulator connected. Does anyone know what the ECU logic is that controls the fuel pump?

Mr. Mike.

beestoys · 09-01-2008, 12:40 PM

So swapping ECU's didn't help or have you not swapped them yet. With everything being checked I would have no fear in swapping them. If swapping doesn't fix it then i would check the circuit to the relay for issues.
