Hi,
I believe it works off the temp sender in the thermostat housing, via the engine ecu.
The sensor does both the temp guage and fan.
To be sure, follow the wires from the fan, if they don't go to a switch in the radiator like the old days, you'll know.
Bob.

What makes you suspect your cooling fan is faulty. To check the system when vehicle is sitting stationary start engine let it sit there idling it will soon reach running temperature then it will soon reach boiling point but just before boiling point your cooling fan has to activate if not then the system is faulty.
