Cooling Fan Control

Based on the request signals from the ECM and traction motor inverter, HPCM transmits the cooling fan control signal to IPDM E/R via CAN communication. IPDM E/R transmits the pulse duty signal that corresponds to the received signal to the cooling fan control module. The cooling fan control module controls the duty of the fan motor drive voltage in order to control the speed of the cooling fan motor. Refer to "COOLING FAN CONTROL: SYSTEM DESCRIPTION ".
