    2012 Jeep Grand Cherokee will not complete the read in VCM Editor

    Takes 6 minutes to try to read and then at 100% completion just says : "Controller Init: Failed"

    Hardware: NGC4A ECM, Dodge

    Try reading via bench harness, IIRC this error means there is a battery or wiring related issue with the vehicle.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"
