Condenser Fan And Radiator Fan Control
WARNING: This page is about a different car, the 2008 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.
The ECM judges the required revolution speed of radiator fan motor and condenser fan motor using the input signals transmitted from A/C switch, secondary pulley speed sensor < CVT > or vehicle speed sensor (VSS) < M/T > and engine coolant temperature sensor.
