Title: Installed Exhaust and Bike Wont Start... HELP !!!!
Post by: jerryj20 on September 14, 2010, 05:13:16 PM
Hey guys, I just installed my new Termi exhaust and ECU.  I took off the gas tank, installed everything and put the tank back on. The bike powers on but it will not show that the bike is in neutral and will not start.  Does anyone have any suggest. about what may be wrong?? Thanks

This one sounds like it out in left, but... is the bike in neutral? You could have possibly forgotten one connection under the tank, unplug and resit the ECU connection.

Just coz I've done this too.... you didnt by any chance accidently flick the kill switch while you were messing around....? Never hurts to check the bleeding obvious first....  ;)  but...

I'm hoping you disconnected the battery terminals prior to pulling the ECU connector?  Seems to me like you gotta retrace your steps, go back over everything coz clearly there's something you missed....  Does the display scroll the "696/796/1100 racing" message when you flick the key?  

Do you have a bike with ABS??  If so.... is you new ECU the ABS iteration?

What happens when you revert to the stock ECU?

Good luck, let us know how you go....

What happens when you turn it on? Does anything work?
Is it in gear? What bike do you have?
Try sitting on it put the kickstand up, pull in the clutch and try to start it.

I'm guessing you got this: http://ducatimonsterforum.org/index.php?topic=37314.0 (http://ducatimonsterforum.org/index.php?topic=37314.0)

1) Is the system the correct year for YOUR bike? (02 sensor)
2) Was the ECU married to the other bike? (immobilizer)
3) Did you marry ECU to your bike? (immobilizer)
4) Is the ECU connected properly?
5) Is the immobilizer light on?
6) Why did you take the tank off?

If you want us to help you, you gotta throw us a make the beast with two backsing bone here...you give almost no information at all...not even the bike model or year.

On my bike the ECU has a separate ground wire.  It's not on the ECU but rather the ECU socket and I think you have to disconnect it when you remove the cover to access the ECU.  Make sure you have reattached that wire.
And on my bike there is no such wire.  Not in anyway saying this advice is wrong... but we really need to know WHAT BIKE... Marelli or Siemens ECU??  If its a Marelli then I have no idea and you should listen to DarkStaR or Carbon 14.... If its Siemens then maybe I can help and you'd need to disregard everything DarkStaR just said.  People wanna help but we need to know......

What bike jerryj20, what bloody bike??

Sorry guys, im super new to bikes...  Its a 05 S2R 800 Dark.  Yes its the correct exhaust bc I bought it from a guy with the exact same bike.  yes the ground wire is connected.  As far as marrying it to my bike, i have no idea what that means or how to do it.  I took the tank off bc i just bought the bike and wanted to clean it up real good.  Hope this helps, let me know if you need any more info,  and also it is a Mag. ECU....   It just seems wierd to me that the green N light is not comming on and the bike is in Neutral....

What happens when you turn the key on?

Do the gauges sweep?
Do all of the 'idiot' lights come on for a few seconds?
Does the headlight come on?
Can you hear the fuel pump run for a second or so?
Title: Re: Installed Exhaust and Bike Wont Start... HELP !!!!
Post by: jerryj20 on September 15, 2010, 06:43:51 AM
Yes to all of the above,  everything comes on.  When the bike is in Neutral the Green N does not show up and when i try to fire up the bike, NOTHING,  doesnt even try to turn over.... Guess its time to take it to the dealership,,

Does the yellow 'check engine' light stay lit?

Was that a brand new ECU?
Or was it a used unit?

Have you checked the fuses?
Title: Re: Installed Exhaust and Bike Wont Start... HELP !!!!
Post by: jerryj20 on September 15, 2010, 07:52:32 AM
Yup checked fuses and all are good,  yellow light does not stay on, and the ECU is used,  not new, 
Title: Re: Installed Exhaust and Bike Wont Start... HELP !!!!
Post by: Speeddog on September 15, 2010, 08:09:18 AM
Go back to the stock ECU to troubleshoot the issue.

I'm 99% sure you're SOL on that DP ECU, as it's most likely been 'married' to the gauges on the last bike it was on.
You may be able to get it reflashed to remove the immobilizer function.

As for the neutral light.

Check to see if the lead to the switch is connected.  Yours will look a little different than the one below, but it will be in the same location.

Thanks for the pic,  also what do you mean by married?  does that mean it would be no good for mine and I would need a new one?  

Also I put the stock ECU back in and still the same problem?

Also I just spoke with the guy that sold me the set up and he said he just bought the setup and installed it himself,  he never used the red key or whatnot and doesnt think he "married" it to his bike.

Hello all,

I am the previous owner of this setup and had it on my 05 S2R for a few years.  System was purchased new as a DP slip-on/ecu/open airbox kit.  I installed the slip-ons, swapped out the airbox covers, unplugged my ecu and plugged in the new one.  Bike fired right up.  There were no extra steps to marry the ecu to my bike.

The fact that his gauges sweep with key on make me think that it is not the ecu that is causing this problem.  Also, he is experiencing the same issue with the stock ecu.  My opinion is that something in the neutral circuit is disabling the starter.

Of course, I could be totally wrong.

I will keep an eye on this thread and in communication with jj20 until resolution.

Did you try to start it with the clutch pulled in and the kickstand up?
Title: Re: Installed Exhaust and Bike Wont Start... HELP !!!!
Post by: jerryj20 on September 15, 2010, 10:49:11 AM
Yes, I tried to start it that way and no dice.....  Im going to check all the neutral cable and kickstand when i get home from work.. Ill check back in.. Thanks  

If the ECU was bad, would the Green N light still come on when i turned the key on and put it in neutral?

I just got off the phone with my local Ducati service dept. 

Tech there states that there should be no issue installing that ecu on another monster.  The only thing that needs to be tweaked at times is the TPS, otherwise it is basically plug and play.

I talked to a few Ducati dealers today and it seems like with each one you get a different answer, just like the " how do i get my pool clear" question :)  Anywho im getting ready to head home and try a few things.  Ill check back in...

Post by: jerryj20 on September 15, 2010, 04:58:05 PM
Tried everything and the bike just wont start.  I decided to push start it and it started. My ? is I assume ill take it to the dealer so is there any harm in me push starting it and riding it to the dealer?  Will it hurt anything?
Title: Re: Installed Exhaust and Bike Wont Start... HELP !!!!
Post by: jerryj20 on September 15, 2010, 06:03:25 PM
Is this the neutral switch?  Is something missing??

That's it.  Now find the wire and connected it.
Title: Re: Installed Exhaust and Bike Wont Start... HELP !!!!
Post by: jerryj20 on September 15, 2010, 06:51:30 PM
I looked for a wire but couldnt find it...   Where does the other end connect and what should the connection look like that connects the the end shown?  could that be the whole reason that the bike is not starting?   Also would it jump start if the ECU was bad?
Title: Re: Installed Exhaust and Bike Wont Start... HELP !!!!
Post by: DarkStaR on September 15, 2010, 07:01:48 PM
 [bang]
It should be there with the rest of the wires/hoses. Mine has white insulation over the connector.

Unfortunately we can not tell you where the wire went, but the signal goes back to the computer, as does the sidestand switch and the clutch switch, since that switch allows the bike to start as long as the clutch switch is disengaged.   If the clutch switch is operable the bike should start if the lever is squeezed and the sidestand is up.  This is a safety system  to prevent you from riding off with the sidestand down and highsiding on your first left.

The fact that the gauges sweep and the immobilizer light goes out means the ECU, key and dash are happy, so you should be looking elseware.  Obviously, first step is the neutral switch wire.

Seriously guys, im new at this bike thing,   i looked for a connection and couldnt find it anywhere,  and you say the other end should connect up towards the ECU?
Title: Re: Installed Exhaust and Bike Wont Start... HELP !!!!
Post by: ducpainter on September 16, 2010, 04:47:58 AM
It actually enters a harness, tells the bulb and the ecu the bike is in neutral.

It does come from above.

It's there somewhere.
Title: Re: Installed Exhaust and Bike Wont Start... HELP !!!!
Post by: jerryj20 on September 16, 2010, 04:59:00 AM
Thanks,  also if the bike start via push start, does that mean that the ECU is good?

If the ecu was no good the bike would not run.  

If you locate the wire that goes to the neutral switch and plug it in I think your problem will be solved.

Thanks Invisible,  last night when i push started the bike i had the old or OG ECU in it,  I will put the one you sent me back in it tonight, and try to start it and also try to find that wire that plugs in.  Thanks again
Title: Re: Installed Exhaust and Bike Wont Start... HELP !!!!
Post by: jerryj20 on September 16, 2010, 04:25:29 PM
BINGO..... It was the Neutral switch, I found where it fell off,  wasnt on tight enuff i guess.  And to think all this headache for one wire. O well,  good to learn about the bike,  thanks for all the help guys.....  And this exhaust makes this sound like a whole new bike   10xs the stock......
