    O.K. a bit of hair splitting, but your car is not OBD2 compliant. That's only used in the USA and Canada. In Europe it must comply to EOBD, which is a good thing, because under EOBD the fault lamp does not go on as quickly as under OBD2.

    It looks like the connector is up side down and you have pin 7 and 15, which means the protocol is either Iso 9141-2 or Iso 14230. Both use the same interface.
    If you search the internet you will find a lot of schematics, but I think you can buy one for just a little more. Don't buy cheap chinese clones, they usually don't work.
    Prices are around 100 US dollar, which usually includes software to read the engine and automatic gearbox.

    If you also want access to Abs, Airbag and those kind of things, you need a professional aftermarket scanner, which are a lot more expensive.

    I don't mean to nitpick, but you probably meant to say "ISO 9141": ISO 9141-2 ("part two") is by definition OBD-II.

    It's the BR-3 interface, available from:

    This DIY interface is ELM327 compatible, which means you will have a wider choice of software:

    Our company makes the OBDLink:

    It's not cheap but is a bargain for what you get. It is available from MP3Car store for less money.

    Unless I am misreading the connector it image, it looks like you have two data pairs populated, 6 & 14 and 7 & 15.

    The schematic you posted will do ISO 9141 and J1850, but not ISO 15765 (CAN bus), which I suspect this vehicle primarily supports.

    You're right, the CAN pins are there, but I think most of the time ISO takes precedence over CAN for OBD.

    No, the only requirement is that only one transport respond to OBD-II requests. You'll see it both ways. On a newish GM, you'll have both J1850 and CAN, but only CAN will respond to OBD-II requests. On a some BMW's just a little older, you'll find both ISO and CAN, but only ISO will respond to OBD-II requests.

    In this case, since it is a Renault and pin 1 is populated, my guess is that J1979 or EOBD is probably going to be CAN (if supported at all).
