Hyundai Genesis (DH) 2013-2016 Service Manual / Engine Mechanical System / Cooling System / Cooling Fan Description and Operation

Description

The cooling fan controlsx the cooling fan motor voltage depending on the duty output from the ECU (Freq.: 300Hz).

[Signal from the ECU to the PWM (SI: 300Hz)]

SI Duty	Motor Voltage (V)	Variation (V)
10%	0	±0.5
30%	4.1
60%	8.2
70%	9.57
90%	more than 12.5	-
