Overview
Cooling Fan Control
The PCM decides the optimal fan drive depending on the signals from various sensors, and outputs duty signals to control the cooling fan motor. By performing a sensitive drive control depending on the situation, it efficiently maintains the temperature of the coolant, and reduces fan noise. ECT sensor 2 detects the temperature of the coolant.
