    MPVI2 Reads normal but write transfer timed out

    I am able to read an 01 Yukon fine but it says "write transfer timed out" every time I try to flash it. Anyone run into this?

    Try flashing via bench harness to rule out a battery/wiring related issue.
    It doesn't have to be perfect, it just needs to be done in two weeks...
