    Can "write" but won't "read"...

    2001 Z06
    I have been able in the past to read and write to the PCM, as well as scan, but for some reason when I connect the cable to the car, I can only write, it does not give me a highlighted option to "read".

    Any assistance is greatly appreciated.
    I'll keep poking thru the forum to see if I can find any similar threads.

    Just means you have a file open. Click file-close to close the file and you'll be able to read a ecm.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    Thanks, Bill, I'll try that.
    edit-makes sense, now that I remember, I did have a file open when I was trying to read.

    I've been bitten by that one a couple of times myself. It would be nice if there was, for example, a tooltip on the "read" button that said "you cannot read with a file open".
