Cooling Fan
FUNCTIONS WITHIN THE SYSTEM
Cooling fan motor receives cooling fan motor operating voltage from cooling fan control module. The revolution speed of cooling fan motor is controlled by duty cycle of the voltage.
INDIVIDUAL FUNCTION WITHIN THE SYSTEM
The cooling fan is composed of the cooling fan motor which drives the cooling fan and the cooling fan control module which supply power.
INDIVIDUAL OPERATION
Cooling Fan Control Module
Cooling fan control module receives ON/OFF pulse duty signal from IPDM E/R. Corresponding to this ON/OFF pulse duty signal, cooling fan control module sends cooling fan motor operating voltage to cooling fan motor. The revolution speed of cooling fan motor is controlled by duty cycle of the voltage.
Component Location
The cooling fan motor and cooling fan control module are installed on the cooling fan shroud.
