    1992 Deville "PCM Data"

    I know how to get into where you can read the data, I just don't know what any of it means, or what the numbers should be. If someone could either explain it or give me a link that has it all laid out that would be great!! Thanks Cadillac Owners!!

    You need a FSM for the data decoding. If it is on the internet anywhere I have yet to see it.

    Maybe I worded that wrong. I meant if the PCM "data" decoding list is on the internet anywhere, I have yet to see that. I think that is called parameters if I remember correctly.
    It will be something like this, but much longer, maybe a dozen or more.
    P0.01 650
    P0.02 195

    P0.01 might be engine RPM and P0.02 might be engine coolant temperature, etc,.
