FUNCTION
MODELS WITHOUT A/C
On turbo models the ON-OFF control and Hi-Low control of the radiator fan is performed by the ECM which receives signals from the engine coolant temperature sensor.
MODELS WITH A/C
On models equipped with an air conditioning system, the ECM receives signals from the engine coolant temperature sensor, vehicle speed sensor and A/C switch, and according to these signals, the ECM turns ON or OFF the radiator main fan and sub fan simultaneously (and also selects the Hi or Low fan speed in turbo model).
