    Default 2007 isuzu cant read pcm

    I have been trying to read the pcm on a 2007 Isuzu Ascender and no matter what I do the read wont get past 32k. I have all of the radio and onstar fuses out and the doors are closed. Anyone have any ideas before I go nuts.

    Just one other question, do you know what software version you are using?
    Although I don't think we have made too many changes to the P12 reading or programming process for some time if your software / V2 firmware is quite old it might be worth updating everything.

    Cheers,

    To add on, upgrade your V2 (have to have a V2, V1 wont work) to the latest boot block and firmware in V8.1.2 and V7.5.5 build 86 (main page downloads then update them).

    Also, Im assuming you're talking about the 4.2L I6 motor and not the 5.3 correct? Select Atlas I4, I5, I6 PCM for that and E67 for the V8.
