Engine Cooling Fan Control

The PCM monitors certain parameters such as: ECT, VSS, A/C on/off status and A/C pressure to determine engine cooling fan needs. PCM controls fan operation through Fan Control (FC) output on single speed fan applications or Low Fan Control (LFC) and High Fan Control (HFC) outputs on 2 speed fan applications.
