Multiecuscan

does Multiecuscan works on a fiat barchetta from 2000?

My barchetta has no obdII interface, but for the airbags there is a 3 pins connector.
For the engine ecu there is a 3 pins connector and for the ABS there is a 3 pins connector.

How can i connect the barchetta with multiecuscan.?

Which connector can i use, and is there a interface from a obdii connector to a 3 pins connector
Who can give some answers?

you can buy from Ebay the following

- 3 pin to OBD
and then

- OBD to USB

run the drivers in your pc and then follow the instructions you can find here

I know, i have already a connection with the barchetta ecu.
Th program works great.

I have already reset the airbag warning light with multiecuscan.

That's good!

I hope that I will connect to my barchetta too!

Did you make any changes to your Obd cable before connecting? I mean with the pins

No you don't have to change anything.
You neeld only a adapter from 16pint to 3pin.

or you make wires to pin 16 = 12volt battery
pin 7 = data line
pin5 = ground
to the fiat connector

I can't find the 3-pin connector for the Ecu.

Ive found the one for bot Airbag and ABS.

My car is a '96 and steeringwheel is on the let side
Ecu sits on the right side (passenger side fotwell),
but I've removed the Ecu without finfin the 3-pin plug

Found a smila contact on the firewall under the plastikk cover, but this plugg seems to be 4-pin...

Hi all!

I have the very same issue with my 95' Barchetta! I have found only the 4 pin connector in the engine bay on the firewall. See the pic:



classic - were you finally able to connect to the unit? It seems there are only 3 pins that are wired, maybe with sufficient luck we could identify which are K and L lines, I assume the remaining one must be ground or 12V.

What do you guys think?

I have done a google search but apart from finding a 4 pin plug for sale in China (with Fiat part number I think...) there is no mention of these 4 pin connectors being used, I think Ducati motorbike have a 4 pin plug but completely different layout. No mention on adapters.

So far I find mentions of this weird plug on 95 and 96 Barchettas.
