Title: M620 totally dead. Can it be the immobilizer? UPDATED! Found the problem
Post by: Starscream on May 16, 2011, 03:45:50 PM
I was going to ride my M620, and you guys know that when you turn the key to on, the dashboard lights up and the needles go up and down, and you can hear the fuel pump priming.

Well, this time, I turned the key to on, I believe I heard like a "click" and nothing happened. The dash didn't lighted up, the needles didn't move. Nothing at all. Tried to start it, but it was dead. The button did nothing. Besides, without the pump working, it wouldn't start lol.

I checked the fuses, all were okay, no signs of broken cables or anything.

The thing is...a couple days before, my friend layed down the bike. It had some "damage", but it was rideable. I came home with her that night. Next day, I went to my local Ducati mechanic so he could get a look at the damage and tell my an approximate bill of repair (so I could show it to my friend).

I didn't rode the bike since I arrived home from the mech. Then, a couple days later, I was going to ride it and the problem described above happened.

I talked with the local Ducati dealership (I live in Caracas, Venezuela), and they told me the ECU is "locked". As in, the immobilizer system actived. How could've this happened? I never let the key for more than 15 seconds without starting it (I think that is one of the reasons the immobilizer kicks in).

Also, since I bought this bike from a guy that got it imported (legally of course) from the USA, I don't have the red key nor the code card (I didn't knew EFI Ducatis had that system, my previous 748 just had a couple keys and that's it), so my dealership told me the only option was for a new ECU and set of keys...which is ridiculously expensive. Is there any solution? Or am I screwed? Is there any way to reset it without having the red key or code?

I know the bike was originally bought at Ducati Miami, could I try to contact them through my local Ducati dealer and see if they could provide the code? Do dealerships have that info at hand? Or only the original owner with the card has it?

Please help, my bike has been sitting a long time, I really need to fix her, since it's my main means of transportation...but I'm broke right now and can't afford the ECU/key change as my dealership recommends (And you know you can't trust all dealerships).

Thanks in advance!

Last time I faced this issue, there was a short in the antenna wire. The antenna reads the unique code given off by your key. It's a ring stuck up inside the plastic covering around the key switch on the bike. I'd start there... it's a very thin wire and easily damaged.

Worst case scenario - send your ECU off to be remapped, removing the immobilizer - about $250 for the service. But that's only if all else fails.

Before doing anything else check the battery!

The dealership may still have a record of the key code, wouldn't hurt to give them a ring with the bike's VIN number to find out.

And then the main fuse

sounds like a good time to bust out the multimeter/voltmeter.

Yes. I described the problem to them and they were the ones that said I needed the code or to buy a new ECU/key set (which here in Venezuela is $$$$$$$$$$$).

I have tested other batteries on my bike, still the same issue. All the fuses (including the main one) seem to be in OK shape. The battery I had on my bike was new, had less than 2 weeks on it, and worked fine on other Monsters.

I'm TERRIBLE with electric and wiring, and don't even know how to use a voltmeter. Guess I'm going to have someone do it for me.

Going to check the antenna wire. Do you have to remove the plastic ring around the key switch to access it? Is it the thin wire that comes down from the key switch then goes around and joins the main harness that goes into the ECU?

Yeah, the bike was originally bought on Ducati Miami, but I believe if I call by myself it will sound really shady, like if the bike was stolen. I will pass by Ducati Altamira later, explain the full situation to them, and ask to see if they can make the call for me. If I bring proof of ownership, I guess they couldn't deny to try to make the phone call, dealership to dealership and ask to see if they have the code.

Thanks guys, I will keep updating this. Hopefully with good news.

Wow I guess they want to earn some money.  Try the other dealer too.  The euro to bolivar exchange sucks so I hope you can figure it out.  You are brave riding a Duc in Caracas

With everyone's permission I'll do this one in Spanish ...

Antes de todo revisa la bateria, no es dificil ... Si tiene menos de 11.5V estas frito, y necesitas otra nueva o darle una carga... Yo tengo una igual y he tenido dos accidentes y nunca me ha pasado esto. Si quieres una ECU, te vendo la mia, enviame un pm y hablamos.

I just said, first of all check your battery, if it has less than 11.5V you're done, need a new one or charge it ... Told also, that I've got the same model bike and have had two accidents and never had such issue. Also offerd my ECU.

Sorry to bring this back from the dead, but I've been really busy with my new job and travelling around the country, so I haven't had much time to post.

I dropped the bike at a shop some friends from the Venezuelan DOC recommended me. Turns out it was a guy that I did some track days with him, so he was really nice and cool with me. Left the bike on saturday.

Today he called me and said he managed to fire up the bike doing some wiring directly to the battery and main fuse (or something like that). The bike fired up without hesitation! He tells me he thinks the problem is one of the wires coming out of the key switch, so he's gonna take apart the wiring and check all of it for a piece of broken wire.

I'm really grateful it wasn't the ECU nor the immobilizer. Hopefully in the next couple days the bike will have all it's wiring properly done.

Wanna thank everyone in here anyways. Hopefully I can stick around to help around the forum.   [clap]
