Setting "fan on" temps via TunerPro is understood, just wondering - how does the 16188051 pcm communicate to turn the fans off?

electrically? there's no need for an 'off' signal, the fan relays are momentary. sends 12v to the relay for on, removes it for off.
in the tune? the temperature is a threshold, not a min-max type value. above the temperature, they're on. below, they're off. it has a hysteresis value to widen that threshold so they don't turn on/off repeatedly if temperature is hanging around that value.
I'm not following your question. The PCM controls the fans directly so it doesn't need to communicate with anything.
Steveo got it

So "hysteresis values" are calibrated with specific time line values instead of specific temperature ranges?

The hysteresis adds the temperature band instead of their being separate on and off temperatures. For example, put 5* in for hysteresis and it turns off 5* lower than it turns on.
Great info...are hysteresis values adjustable within the 16188051 environment?
