2001 929 red light

bladeracer · 01-10-2009, 2:54 AM

Assuming you mean the valve in the exhaust you can simply watch it to see if it's moving at all. You can also hold it in place and see if the noise stops.

mma_fighturr · 01-10-2009, 3:19 AM

ok thanks for the help guys. Ill go in the shop tomorrow and sort it out. Ill tell him to remove the valve and the cables but make sure the motor is left in and twist it to shut that light off. Then ill see about that rattle and post again tomorrow when I get back!

roughneckin · 01-10-2009, 11:03 PM

I had a funny rattle on my bike and it was just a piece of the windscreen rubbing against the fairing. Also I have a small rattle when I am first revving up and it goes away, has not been a problem so far...KOW

mma_fighturr · 01-10-2009, 11:32 PM

Hey roguh neckin I have a new thread for this problem. The cover is off and the engine is about to be split... I am determined to find this problem lol ( os im not doing this work so I cant take credit for this one) Heres the link to the forum post...

929 Odd engine noise

Theres new pics as well

mma_fighturr · 01-17-2009, 4:53 AM

Ok so the Servo motor is fried and the gears are stripped. I think im gonna go with what was said on here and just tell the tech to take the cables out wire the valve open and what ever else needs to be done. Im guessing you leave the motor in so the ecu reconizes it and to get rid of the red light I adjust it a bit?

Im just confused how to make the light go away.

bladeracer · 01-17-2009, 6:50 AM

The light will only go out if the ECU recognises the servo motor is there and is in the correct start-up position.
It may be possible to discover exactly what signal the ECU is looking for and make something to trick it but I doubt it's worth the effort for anybody to do it.

yup. and if the gears are stripped it will constantly try to search for the correct starting point when you cycle the kill switch on. you can always reach your hand up there and turn it till it stops but that gets old fast.

no one has made anything yet to bypass the servo, probably because in order to simulate it you're probably gonna end up with something as complicated as the motor itself so there's no point.

Somebody has done that for the 600RR and the '04-'07 1000RR. It does not work on the '08 so Honda has changed something; albeit the wire colors and the internals look identical. It is possible for someone with electrical engineering skills/degree to figure it out. All it takes is a diode and two resistors. The easiest is to leave it there though.

mma_fighturr · 01-17-2009, 1:57 PM

Ok thank you, im going to do that and let the light flash its code. What I wasn't sure about was if it could blink out more than one code at a time but I know now it can. I was reading a previous post and found it kind of interesting, Lanbrown was talking about it robbing some HP with the red light going. This does make scense, just like in my subaru the ecu puts the car in limp mode and wont let me stomp the peddle to the floor.

But im sure 3-6 HP wont be to noticable, Im used to riding older 600's like the fz and old zx6r so im sure i'll be happy with the performance of this bike. Thanks for the help im going to the shop right now and going to get this done.

lanbrown · 01-17-2009, 2:02 PM

The bigger issue is that the light is on all of the time and if a more serious issues does arise, you won't know it. Even if you check the codes on a regular basis, you don't know when the latest code started.

mma_fighturr · 01-17-2009, 2:05 PM

Couldn't I check the light every start up? It will blink the code 35 then If another problem arises it will blink that other code after its done blinmking 35 correct? This then comes down to me making sure I check the light at every start up?

lanbrown · 01-17-2009, 2:10 PM

You can do that, seems like a lot of work though. What happens if you are riding and something serious comes in? You get to your destination that is a few hundred miles away and learn it is a serious fault?

bladeracer · 01-17-2009, 2:47 PM

I would expect any kind of serious fault would be noticeable before the light indicated a problem.
The warning codes only cover a very small number of possible errors anyway. It's just a means for making more efficient diagnoses.
The five sensors (MAP, ECT, IAT, TPS and speed sensor), the four injectors, the servo motor and the cam and ignition pulse generators.

lanbrown · 01-17-2009, 2:52 PM

If you are just cruising along, you may not find the fault until you give it some gas. My father had a car (60's) that developed a few issues and start to miss and sputter so he slowed down to about 70. No issue, so he accelerated again and it started to miss and sputter,s o he dropped it down a gear and didn't have a problem. The following day he had a hell of a time getting it started to go to dealer. It did, he got to the dealer and they couldn't get it started. The cam gear was shot; the manufacturer decided to use nylon on it and there was only one tooth left on it.

bladeracer · 01-17-2009, 2:56 PM

I've seen those crap nylon cam sprockets.
Ford 302's had them.
Not sure what relevance it has to error codes though?

lanbrown · 01-17-2009, 3:01 PM

The relevance is simple, if you want dependable transportation, you are best to fix issues. if you don't, another issue can arise and cause damage or a lot of inconvenience. Let's go back to that couple hundred mile trip. if the light was not on and a mile from where he left, it turned on, you would investigate it immediately. If the light was always on and an additional fault was found, he wouldn't know about it. Now let's just say that the fault caused the bike to be unrideable, now he is far from home and has to figure out how to get the bike to the dealer or home; both of which could be costly; more than said servo motor. You can have a fault that may not be immediately noticeable, but will down the road.

the computer won't drop power because of the error. cars will do it because people are dummies.

Honda had the ECU drop power on the 1000RR if the servo motor is not there.

bladeracer · 01-17-2009, 3:27 PM

Yep, I'm not aware of any "limp home" mode on the 929 or 954.

If the fault makes the bike unrideable then you don't need the error light to tell you there's a problem.
As I said, it's a _diagnostic_ tool only. You know there's a problem first so you pull the codes to diagnose it.
Of course, we still find people that happily ride all the way home with the oil light on. Whatever happened to that guy with the GSXR that dumped all the oil?

Not true at all; read the story of the nylon gear. Normal speeds it was fine and thus if it had a light, it would have illuminated. Since it really had an issue at higher speeds at that time, you would have to be exceeding the speed limit to notice it. The following morning, it was well known that there was a problem and off to the dealer it was going to go and it was a PITA to start. Imagine if you didn't know there was a problem; well, you do now. Imaging if you were out in the middle of nowhere just getting fuel and found this issue. A tow truck is not cheap, not the time involved either.

If someone wants to ride around and not know what is going on, that is their choice. If/when there is a problem, don't expect sympathy and if the repair job costs even more, consider it a lesson.

Larry, you know the risks and are willing to deal with them, others may not.

mma_fighturr · 01-17-2009, 6:48 PM

Interesting. I will be replacing the servo motor in a few months when I can afford it. For now im going to just take the cables and the motor out. It turned out It was nothing to do with the spring or the exhaust valve or anything which kinda sucks so it might be a bit more of an expensive fix.

dboy954 · 07-27-2009, 11:53 PM

I have a problem with my 2001 929 with the fi light on now. I put in a full header and exhaust on and now the fi is on and as well as the flashing red light. What do i to resolve this??

BurtonF166 · 07-28-2009, 12:27 AM

When you removed the stock exhaust, the HTEV exhaust valve is removed as well. This piece is connected to a servo that controls it's rotation between 0, 90 and 180 degrees and the airbox flapper. The code you receive is 34 or 35. It is not an issue since it does NOT affect performance, yet if you get annoyed by it, simply re-connect the servo, and reset the ECM per manual procedure.

If it's because you removed the servo motor I hope you removed the flapper valve from the airbox as well?
You need to count the long and short flashes to know which code(s) it's throwing but it's almost certainly for the servo motor.

Thanks guys for all your help...
