The ECM will activate the coolant fan relay when engine temperature is above 227°F, air conditioning is turned on, or the coolant temperature sensor fails. Any of these input signals causes the ECM to ground, circuit 536 on 2.3L VIN D and VIN 3 engines and circuit 535 on 3.3L VIN N engines, when vehicle speed is less than 35 mph. When circu...

If the ECM fails on the 6 cylinder engine, the redundant coolant fan switch will ground the 335 circuit and energize the coolant fan relay. The ECM will ground the coolant fan relay when the coolant temperature sensor indicates the coola...
