Hi Guys, The error code is fluctuating between 37.3 and 38.0. I know that the 37.3 is the immobilizer cable disconnected, but what is 38.0?
38.0 is a CAN error. Try taking both connectors off the ECU and checking the ECU pins and carefully clean them. You will see 4 torx screws holding the ECU to the heatsink. Take these out, separate the two and check for corrosion underneath. Clean with wet and dry paper. Check the dash connector and clean. Check the earth flylead onto the ECU and clean.
Hi Big chris as I said...."I`m stuffed" for ideas if EFI got above 37.7 (see code list) ha ha hope you get it sorted by ChrisW answer. best of luck. Ian
Hi Chris. I was on with the garage who had previously worked on the bike and they are going to collect it at the start of next week. I'll let you know the outcome. Cheers for all your help! GBY!!!
Hi Guys, I'm gonna need some initial help. Can any of you tell me where to locate the ECU on my 2004 Ducati 999 Biposte? I want to check all the connections I can as advised by ChrisW, checking for corrosive wires etc. I'm a newbie to this and need a walk through this as garage charges are quite high.
Hi Ian, As per recent posts, I have two errors. 37.3 and 38.0. 37.3 being an immobilizer connector disconnected 38.0 A CAN error. ChrisW advises that I clean connections etc, but not too sure where the ECU etc is. Can you advise?
The ECU is on the lower left hand side of the bike. Remove the fairing, the battery, the battery box and the heat shield on the back of that box. The ECU is on the lower right of that box if looking from the left side of the bike, with the box held as if fitted. It has two large black connectors fitted.
Chris do you need a copy of the manual? There are plenty of links on this site that you can find it on, I can help you out if you need it. It tells you everything.
Hi Tom, That might be handy Tom? Can you send one to me at [email protected]? I have taken the ECU off. Removed the back plate, with some resistance I must say. One screw on the back plate was corroded and sheered. I have a new racing ECU. Can I replace the old one with it or do I need something else to install it? Have noticed that it is slightly wet with oil. Is this normal?
It depends on the map and exhaust. The bike *should* start and run with the racing ECU regardless of the exhausts you have fitted but I don't know what trouble this will cause. Mine was always dry so I don't know if it is normal to be coated in oil. Perhaps check for leaks elsewhere on the bike.
Are you sure the race ecu is either uncoded or coded to your bike otherwise its nfg. Ecu should not have oil on it.
I bought a complete ignition system for this bike with the racing ECU included. But was going to leave it to my mechanic to do that. But thought I would clean and check what I could before leaving it with him. I guess the Ducati mechanic will change everything and re-reg the ECU etc for the bike? There was a little corrosion on the silver back plate of the old ECU. Could this be the problem? I also noticed that the taping to the wires etc were a little wet with oil. But no leaks have been found. I'll dry everything off and put all back together. But don't think this will solve all of my problems with starting. We'll see??
It depends who is the mechanic. The 749/999 immobiliser works off the ECU and the clocks, so you need to have matching codes in both. To use another ECU with the same clocks they need to be virginised by a flashing wizard and it costs about £90 in the UK, although it's 25Euro in Europe somewhere. There's a link around somewhere...
Most DP ECU's we're never coded to the bike when fitted. Dealers realised that bikes may be returned to stock before sale and this would allow the DP ECU and exhausts to be sold as a job lot. You will probably find the 2nd ECU will work with your bike.
Thankfully the mechanic works for Ducati Ballymoney N.Ireland and has all needed to re-virgin everything. I bought the clocks, the keys, the card, ECU key socket etc. So they should be able to renew all that thankfully. I'm going out now to put the jigsaw back together after I clean everything and dry everything off. I found another old ECU and will use the screws and back plate of it (not corroded) and that will help I guess. I'll keep you posted on progress Tom.
It would work but be rich because of the stock exhausts. If it cures your starting issues I could always help with cloning it to the map in your stock ECU.
I changed the ECU to another one which I had, which wasn't a racing ECU. The problem still there. The old ECU was in perfect working order. Have cleaned and dried all wiring etc surrounding the ECU. Checked the dash connectors also. All ok. So now I will leave it with Ducati to sort as I don't know what else I could do....Cheers guys!
Chris It it turns out to be an immo problem then I have a loan ECU that I can send out to you to test. It's out with another forum member at the moment who has successfully got his bike started with it. The offer's there if needed, all I ask is that it is returned promptly and P&P is covered.
