    Vehicle Interface

    Indeed, my understanding is that the OBD-II interface is a post-1996 requirement set forth by the U.S. government. As in, all cars from 1996-onward that are sold in the United States are required to conform to a specific set of data standards that is uniform across all auto makers.

    Other countries might have similar requirements, but these requirements might not be the same standard as OBD-II.

    But that said, ALL cars sold within the last 10 years will have some kind of data interface-- These days it's a necessary element of diagnosing vehicle problems, and all cars will have them.

    In fact, I'd bet most cars from the late 80's-onward have some kind of data interface. As noted, it wasn't until 1996 that U.S. law mandated a standardized format, but most cars had something, even if it wasn't OBD-II. My 1990 Geo Prizm GSi hatchback (aka Toyota Corolla clone; a Corolla "Seca" 'down under), for instance, does have a data interface located in the engine bay labeled, "Diagnosis".

    Nissan have had their own kind of OBD for ages called consult, the main reason I'm building a car PC is to be able to monitor my cars ECU (an 89 300zx). You'll probably find the connector near the hood release, here's some info: http://www.plmsdevelopments.com/consult_if.shtml

    From SiliconChip Feb 2010... "All new cars sold in Australia from 2006 onwards are required to comply with the Australian Design Rules (ADR) to include On-Board Diag*nostics. This is called OBDII...".

    The above is "public" and is from A Look At Automotive On-Board Diagnostics.
    See also An OBDII Interface For A Laptop Computer.

    Both the above are from Silicon Chip magazine, Issue 257, February 2010.

    Places like Jaycar often have back copies (and at reduced prices!).

    I should have a copy somewhere in my shiles of pit.
    It may give insight as to what cars have OBD in Oz. (And whether it is called UBD = Under-Board Diagnostics. ... down-under ... get it? And before any of you anti-Coriolis hemisphere residents shut pit on my humour, may I quote a recent movie... "Orstralians... they shoot things don't they?"!)

    Hi monkers,
    On your car there will be a yellow connector underneath the steering column. It isn't OBD-II either I'm afraid. The only affordable scanner that I know of that works with your car is www.ecudatascan.com

    Thanks,
    Rezista

    @Oldspark: Any chance you could email a scan of that issue? I have been trying and trying to locate a copy of that issue, but keep coming up empty. Can't seem to source it in Canada. It would be much appeciated!

    Nope. No way. Forget it.
    LOL! I'm not being nasty, but I don't have that copy.
    So tuff luck... ha ha....

    BUT!!! I did see a copy in a local electronics store. I did consider buying it....
    When I return, I'll re-check & probably buy it....

    I'll let you know.....

    BTW - back issues else electronic copies (etc) can be purchased from Silicon Chip. (As a last resort...)

    Funny what some will do for others.....
    But stupid me. I bought the remaining copy mentioned above. I now know I definitely had it. Is it here, or did I lend it to someone? [Note to self: Remember my forgetfulness! Or remember to tidy up.]

    The Australian Silicon Chip February 2010 edition features some good articles like "A Look At Automotive On Board Diagnostics" (pp10-17) and "A Multi-Function GPS Car Computer (part 2)" (pp78-84). Both provide various weblinks to info (like sensors, software etc), and the former states that "All new cars sold in Australia since 2006 are required .... to include OBDII".

    Its "Build an OBDII interface for a laptop computer" (pp24-35) uses a PIC-based ELM327 interpreter & MCP2551 CAN chip, plus MAX232 RS232 comms chip and other common trivial components.

    Designed to interface between a laptop etc serial interface or serial-USB converter and OBDII socket.
    It is powered from the vehicle's OBDII port and is hosed in a 111 x 60 x 30mm diecast box. Its PCB is 90 x 55mm (with highest component being the 4MHz crystal or DE (DE-9) connector (aka DB-9 connector for those that don't know better.)
    It shows real-time data, can clear the trouble codes & MIL.
    It handles CAN, ISO, KPW,& VPW protocols.

    The PC can use any of the 3 detailed driver softwares, or other softwares mentioned (will Aussies use wOBD LOL!?).

    Mason - I'll PM you.....

    PS - now I read the last page and it's obvious I had it. But I was looking for it recently.... and I thought it was for this thread. [Note to self: ?]
