    can anyone recommend a code reader for my 94 850 turbo? it apparently
    requires the OBD1 interface
    and I cant seem to find one that works on a volvo

  2. Perhaps it is actually OBDII? ScanGuage claims their product is compatible
    with the '94 850 turbo 2.3L - see http://tinyurl.com/y5jjby They want $170
    US for their product, but if it is actually a standard OBDII interface you
    can do better. Most auto parts chains in the US now offer free OBDII code
    reading, so that would be a good way to tell without putting up money.

    By the way many parts chains in Canada also do it free. I had them do
    my 98 V70. It is OBDII.
    Call around.

    The best reader is already installed. It's a bit tedious, but:

    Even though this is for the 700/900, procedures for your early 850 are
    the same.

    Replace tt with t (twice!) and remove parentheses to email me directly.
    (But I check the newsgroup more often than this email address.)

    One of the better things about the 94 is that you don't need a code
    reader. Look under the hood, on front of the computer housing. Two
    connector blocks, A and B, with a wire, LED, and button.
    To read the engine codes, plug the wire into A2, and press the button
    once. Watch the flashes (3 times, pause, 2 times, pause, 4 times =
    3-1-4.

    Press it again, and you get the next code if there are more than one.
    You can also use it to clear the service light.
    One good source of info is here:

    If you plan on keeping the car for a while and maintaining it
    yourself, I strongly suggest getting the excellent factory service
    manuals, which contain troubleshooting procedures for each code.
    If you have the original paperwork, there should be an order booklet
    for the manuals. (They used to be available via their website, but I
    can't find the link right now.)

    (Note, the manuals and code data aren't available to owners on new
    models, which is why I own an Audi now.)
