Radiator Fan Control

RADIATOR FAN CONTROL





- The ON-OFF control of the radiator fan is governed by the ECM which receives signals sent from the engine coolant temperature sensor.





- On models which are equipped with an air conditioning system, the ECM receives signals sent from the engine coolant temperature sensor, vehicle speed sensor 2 and A/C switch. These signals simultaneously turn ON or OFF the radiator main fan and radiator sub fan as well as setting them at "HI" or "LO" speed.
