The cooling fan(s) are actuated by the powertrain control module (PCM) in vehicles with an automatic transaxle or the engine control module (ECM) using a low-speed cooling fan relay and a high-speed cooling fan relay. On A/C-equipped vehicles, a series/parallel cooling fan relay is also used.

The PCM or the ECM will turn the cooling fan(s) on at low speed when the coolant temperature reaches 93C (199F) and high speed at 97C (207F).

The PCM or the ECM will change the cooling fan(s) from high speed to low speed at 94C (201F) and turn the cooling fans off at 90?C (194F).
A/C ON

The PCM or the ECM will turn the cooling fans on at low speed when the A/C system is on. The PCM or the ECM will change to high speed when the coolant temperature reaches 115C (239F) or high-side A/C pressure reaches 1882 kPa (273 psi).

The cooling fans will return to low speed when the coolant temperature reaches 112C (234F) and high-side A/C pressure reaches 1448 kPa (210 psi).
