    Hi Guys!,

    More than happy to be part of this great family. I am the happy owner of a 991 GT3RS but one of my best friends has convinced me that it is time to buy the car of my dreams when I was in school... a beautiful 348!. Time to join the Ferrari family!.

    My friend has different Ferrari (458 Spyder and 488) and he does every diagnostic with his Leonardo Diagnostic tool. I need your support because he just told me that he will need an specific cord to connect the OBD to a 2.7 348 (kind of a bridge). Do you know what cord is it?.

    Thanks a a lot for your help!. I will post some pictures from the car as soon as I have it!. I tested 3 weeks ago with my friend and I loved it!.

    It does look like the connectors should fit....

    But, even if it did, the OBD1 diagnostic features on the 348 may not be supported by the Leonardo. What is it you are trying to do with the 348?

    My mechanic would like to check the overall status of the car and make sure it is perfect without any problems. He will do the major service and it is a great opportunity to check that everything is fine. He has the Leonardo diagnostic tool as it is the one he uses for the cars from other customers (458,488,430 etc.).

    Affirmative, no OBDII functionality until Motronic 5.2. SD1 used serial connections. SD2 and SD3 came with SD1 emulation modes, not sure about Leonardo. Even after 5.2, Ferrari still used serial connections for some functions.

    What is the best way to get some data from the ECU?. How do I know about possible errors?.
    Mine is a Motronic 2.7

    There's a sequence you do and count flashes on the dash.

    I saw that on YouTube, is that the only way for the 348. No additional option?.

    There is a factory diagnostic tool but only ever saw it at dealers. Even then it was used to do things like measure air for setting throttle air screws etc but you can do it externally as well its in the manual No such animal as the Leonardo for the 348. You can pull ecu codes but honestly if you have then the check engine light would be on assuming the bulbs are not burned out. Do a compression and/or leak down. Everything else is easy to diagnose and fix. good luck.
