I honestly don't know off the top of my head what is normal voltage for that circuit. And as I said in another thread, looking up part numbers, or in this case diagnosis procedures, is more time than I want to put in here on this forum.
If the procedures you have have been followed to the letter, and you're at the "substitute known good PCM" stage, then you're best off sending it to the dealer. Since even if the PCM gets replaced, the dealer has to program it for the Immobilizer keys.
