I found many of the questions I had along the way answered here but some of it was confusing so I thought I'd put together another users guide to help out a bit. To begin with I'd like to thank jpl for his fantastic work and support and may I suggest if you find Jpdiag useful and you're in a position to, that you show your appreciation by way of a donation for providing this excellent program for FREE!!!. Please do the right thing as it seems someone has already ripped it off to some extent and is selling it on ebay (Poor Form!!). Also a thank you to the following members: chrisw, iang27 and wayne111 and tonered from ducati.ms as I have utilised extracts and or advice from their various posts to pull this together.

Jpdiag (DD) will allow users to do a number of things in it's basic form however it is possible to add further functionality for a small fee just contact jpl for further information.

As I presently understand it (and I'm only just getting started myself) there is a program for older bikes(ducatidiagOld_ecu.exe ) presently downloadable here: http://jpdiag.akress.com/download.php It is for p8, 15m,15rc,16m ECUs.

jpl has also created courroies, which is a belt tensioning program.

There's also the program I'm using, Jpdiag23 which is for newer models. Here's a list of compatible bikes, please note it's not exhaustive: http://Jpdiag.xooit.com/t9-Liste-des-motos-compatibles.htm

You'll need to purchase two cables these are:

1.) VAG-COM KKL 409.1 OBD2 USB Cable http://www.ebay.com.au/itm/260970451109?ssPageName=STRK:MEWNX:IT&_trksi…
2.) Fiat 3pin Alfa Lancia to 16 Pin Diagnostic Adaptor Cable OBD2 002 http://www.ebay.com.au/itm/251023149936?ssPageName=STRK:MEWNX:IT&_trksi…

At some point these links will expire so the sellers name is "verymech" (http://myworld.ebay.com.au/verymech/?_trksid=p4340.l2559). I sent a note with payment suggesting he send both cable together, which he did, and as stated on his auctions he doesn't charge for post. I can recommend this seller. The VAG cable comes with its own driver - ignore it and download this driver.

Driver Download: works for XP, VISTA and Win7
http://www.ftdichip.com/Drivers/CDM/CDM20824_Setup.exe

!!!! IMPORTANT !!!! --> INSTALL THE DRIVER BEFORE CONNECTING YOUR CABLES !!!

Once you've downloaded DD you'll need to unzip it to whatever folder you want (I didn't need any special program, Vista managed it). From what I recall there was a few steps and being in French I didn't understand everything it was proposing however I believe the 1st screen ask you to close all running apps, the 2nd screen asks you where you want to install DD. There's also is a donation request, a note here, once ducatidag is opened you'll also find there's a button facility to initiate a donation, it's permanently in the program so you can do it at any time. I think I went in circles a bit but generally I stayed away from the quitter or something similarly named and the Oui is of course "yes" so click it.

As you launch dicatidiag you will be presented with a screen displaying 3 picture options of your cable setup. Choose which one corresponds with yours when the time comes.

There's discussion of this forum due to concerns that some Alpha cables may be sleeved incorrectly i.e. that the positive lead is sleeved black and the negative red. I can confirm the lead I purchased is operating safely.

To be safe check yours before you connect to anything at all by doing a resistance check with a multimeter:


You'll see at the linked page below a picture identifying the operating pins on the OBD cable. The pin you need to check is #16, it is positive power so set your mm to ohms and connect one probe to pin 16 and the other to the red alligator clip. Now since the pinout image on that page is of the OBD cable you need to translate that to the female recepticle of your Fiat cable. I simply inserted a largish sewing needle into the corresponding female pin hole and connected the mm probe to it to check continuity. Check your negative while you're there too if you like, it's pin #5. Pin #7 is the K line which you needn't concern yourself with.

Pinout Picture and Jpdiag instructions at Desmodromico:
http://www.desmodromico.com/public/index.php?option=com_content&view=ar…

That's your polarity check sorted. DO THIS BEFORE YOU CONNECT UP TO ANYTHING !!!

At this point you should have installed the correct driver and Jpdiag.

Before launching Jpdiag I connected my cables up -

1. Join the OBD and Fiat cables together and plug them into the usb of your computer.
2. Check in Device Manager under Ports which COM port the cables are using. I've seen here where people suggest using some number 10 or below but I'm using Vista and it came up as 12 and seems to be fine. You will need to know the port number in case it needs correcting in DD. DO THIS BEFORE CONNECTING TO YOUR ECU. If you select the device listed under ports and right click, go to properties and in the drivers tab you can check to make sure it's operating with the right driver which should be FTDI.
3. Connect red alligator to pos battery and black to either neg battery or a good earth on your bike.
4. At this stage a little blue LED came on in the OBD cable. I don't know if all manufacturers had this facility.
5. Launch DD and select your cables.
6. Once the program interface opens you'll see a connect button alongside a field into which you'll need to enter what COM port you're using.
7. Check the ini field setting - IAW59M use 'slow ini' IAW5AM use 'fast ini'
8. At this stage you can do another test on your cables. Set your mm to 20v and do as ? (sorry lost post page don't recall author) recommends i.e.-

Click Cable Test -
Connect the +ve and -ve fly leads to a 12v power supply e.g. your bike battery but do not connect the diagnostic plug. Set your mutimeter to 20v and connect the +ve lead on the meter to the single outer pin in the Fiat Adaptor. It should look like this - | - -. Connect the -ve lead from the meter to the middle pin or the -ve terminal on the power supply.
Click on the connect button and the KLine 12v and KLine 0v tabs should become selectable
Your meter will read in excess of 12v straight away. If you have the correct com port you will be able to click on the KLine 0v and the voltage on your meter will drop to 0.3v. Click on the KLine 12v and the meter will read over 12v.
If you don't get this behaviour then the KLine is not working so check your setting (probably Com Port)

9. Now if everything to this point is in order go ahead and connect your Alfa lead up to your ECU.
10. Click the connect button which is near the port # field and you will see on the screen "connecting", I waited a little while then turned the ignition key on and like magic on the left hand side in DD you'll see the basic ECU data. Copy it and post it in the request license forum and you'll get a message back from jpl which will be a link to download the file from sendspace. This cle.lic file then needs to be copied into the Jpdiag directory as this post shows:
http://Jpdiag.xooit.com/t1478-How-to-enter-the-cle-lic-release-key-into…

This is as far as I have come in my journey, it's the process I used successfully but do further reading or speak to your mechanic if you're not sure what you're doing. I hope this helps.

Gathered from other members posts:

If you are still having problems try using this utility to remove the FTDI drivers completely
http://www.ftdichip.com/Support/Utilities/CDMUninstaller_v1.4.zip
Instructions http://www.ftdichip.com/Support/Utilities/CDM_Uninst_GUI_Readme.html
Then reinstall using http://www.ftdichip.com/Drivers/CDM/CDM20824_Setup.exe
Don't plug the lead in until you have run the driver exe file.
Here's another nice utility for changing the com port http://www.ftdichip.com/Support/Utilities/Reassign%20COMNo%20Utility.zip
Instructions http://www.ftdichip.com/Support/Documents/AppNotes/AN_160_COMPort_Assigment_User_Guide.pdf

Some of the common problems we come across with connection are:
Plugging the KKL lead into the computer before installing the drivers causing the default drivers to be installed
Using the drivers supplied with the KKL lead
Not installing the FTDI drivers from this exe file http://www.ftdichip.com/Drivers/CDM/CDM20824_Setup.exe and then plugging the KKL lead into the PC
Wrong com port setting (use device manager to identify) then change the value in Jpdiag
Using newer combined KKL/CAN leads rather than just 409.1 Vag Com KKL
Wrong ini setting - IAW59M use 'slow ini' IAW5AM use 'fast ini'
Not having the ignition on when connecting
Poorly charged battery
Faulty KKL leads
There are some useful utilities in this post http://Jpdiag.xooit.com/t1636-monster-695-not-connecting.htm

Many thanks for the tutorial, been poking around in the dark until i found this
I am still having connect issues at times, what operating system are you using, i am using Win7 and have heard it can be a bit temperamental.

Make sure you use 'XP Compat mode' and 'run as administrator'
