Other circuits may be in play that add to the resistance of the circuit, if that makes sense.

What I mean by this, if you purchase a PCM out of a justifiable fit of diagnostic rebellion and find that the resistance on the circuit in question goes back to normal range I would not connect the battery until you exhausted all checks to insure nothing could have caused the PCM to go bad.
