Radiator Cooling Fan Motor: Description and Operation
ENGINE CONTROL COMPONENTS
Fan Control
The PCM monitors certain parameters (such as engine coolant temperature, vehicle speed, A/C on/off status, A/C pressure) to determine engine
cooling fan needs.
The PCM controls the fan speed and operation using a duty cycle output on the fan control variable (FCV) circuit. The fan controller (located at or
integral to the engine cooling fan assembly) receives the FCV command and operates the cooling fan at the speed requested (by varying the power
applied to the fan motor).
