    In some ignition systems the PCM supplies a low reference circuit in the ignition coils themselves? What is function of that particular circuit ??


    Thanks a lot ...

    All that comes to mind is misfire detection somehow or other.

    I don't have my GM software on this particular PC but I'll bet Jaguarjoe is correct.

    Please elaborate on the make/model/year of the car.
