Most bikes have a obd diagnostic plug with which to read fault codes etc.
I see in the manual that there is a diagnostic connector under the seat but it does not have an obd or obdII type connector.
As almost all engines manufactured after a certain date are required by law to have access to the ecu for emmissions control i was wondering if the obd connector on the morini had just been replaced with a non standard item so that us amateurs can't acccess any technical info.
Any help appreciated

I don't know much about motorcycle obd but i'm pretty sure the obdII plug (J1962) is a car and light goods vehicle only thing so probably doesn't apply to the morini.
I haven't looked but i suspect the connector on the corsaro is just 2 signal wires, which is all you should need, although you might need to hook up the power too.
When I get a chance I'll see if I can make up a loom and connect up the laptop and see if I can talk to the bike.

I just found a obd II plug on my other bike and was surprised to find a cheap obd reader would let me read the fault codes and reset them if necessary.
I'm sure the workshop "dongle" will be for access to the adjustment and tuning etc as it's specially written software.
Most of the fault codes are standardised as they have to conform to a eu set of rules.
e.g a fault code for a ford van ignition coil failure is the same code for a honda bike.

your starter for 10. I've not had much time to investigate as it's the wife's birthday and I'll be in trouble but...
Although there is no obdII plug on the morini you should be able to connect the morini diagnostic plug to the right pins on your scan tool. I just tried battery positive to pin 16, battery negative to pin 4 and the orange wire of the diagnostics plug to pin 7. This should be all you need for kwp2000 which I think is what the morini uses. Hooking up in that way to DIagRA let me see a speed sensor fault code and some ems parameters although the numbers didn't look right. The main thing is it did talk!
When I get more time I will look further but see what your tool can see. You could also try pins 6 and 14 (CAN high and low)

Thanks for that.
I thought the manufacturers might be putting different plugs on to dissuade joe public from looking.
I'll try getting some loose connectors and wire and see if i can get my code reader to get any info by linking the corresponding pins.
The reader i'm using was off ebay UNIVERSAL OBD2 II CAN BUS Fault Code Reader Scaner U480 about £23
It's only a basic unit able to diagnose fault codes and reset or erase as required, but useful if the bike strts playing up.

We don't do motorcycles at work so I don't know 100% how the rules apply to them but for cars the manufacturers aren't allowed to put different plugs on- the OBDII plug is mandatory for new cars and certain parameters plus fault codes have to be available to be read by any scan tool.
The morini plug will be different because the EOBD regulations don't apply for some reason and so morini aren't forced to fit the OBDII connector.
So why does your other bike have an obd connector and not the morini? it could be because the morini is euro 3 and perhaps your other bike is euro 4 (I think EOBD was introduced for Euro4). It could be a market thing- The USA have different rules and since the morini isn't sold there morini don't need to comply with their regs- that may not be the case for your other bike.
I think the best we will be able to get for the morini is to see fault codes. I've got a pretty comprehensive scan tool with lots of (car) manufacturer specific diagnostic datasets and as i said at the weekend I can see fault codes on the morini but not the mandatory ems parameters which you can see with any scan tool (ecu mode 33)- I'm pretty sure that means the morini doesn't (and doesn't have to) report the mode 33 parameters, which means you are unlikely to get much information from most scan tools.
When I get a chance I will have another look with my laptop.
The most important thing is that we are lucky to have a good (and growing) set of dealers in the UK and we have exceptional support from the factory so I would have no hesitation in using the dealer network if I ever had a problem with my morini.
I think the only thing I would actually use the diagnostics plug for if i could is logging ems parameters during rides/trackday- would be interesting to see what speed/rpm/fuelling the corsaro actually runs round cadwell...

Hi Guys 
just thought i would have a look see to how everyone is doing 
I'm back on a V twin again (SV 1000s) which is so good its only fault is, its not Italian. Perfect fueling, 50mpg ridden with verve! very underated bike.
Back to the issue,the "dongle" as twisty say's is just for Morini software authentication, all that had a disc off me will have the factory diagnostic software included which is great for resetting parameters, fault finding, and service reset's etc. At the time I loaded this onto a dealer's computer I found it ran better on W98 than XP due to lead supplied from the factory which connected to a serial port (RS232 9pin) not USB!! So if you can find a crack for the software this would be a great advantage then you could modify or do your own updates!!
Regards to you all and keep it shiny side up

As was said in the previous posts the dealer network offers good levels of service. I found 3x service second to none.
The diagnostic issue was more about knowing your own bike than trying to outdo the dealer.
Its a bit like computers years ago when everybody was frightened of them and now they are ten a penny. Nowadays folk are frightened of diagnostics as they see it as some sort of magical art.
The workshop manual is a great help for those of us who are miles from the dealer and need an insight before contacting the dealer.
