Radiator Fan Control

1. WITHOUT A/C MODELS
The ON-OFF control of the radiator fan is governed by the ECM which receives signals sent from the engine coolant temperature sensor and vehicle speed sensor 2.




2. WITH A/C MODELS
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.
