Don't you just love these Ford diagrams?

Although the PCM power relay and the IMRC module includes diagrams about what goes on inside, the PCM has nothing, leaving the interpretation of what goes on inside up to your imagination. This is not very helpful in diagnosing problems. Therefore I must imagine that the PCM has a crystal ball that tells it when the secodaries are open.
