Radiator Cooling Fan Motor: Description and Operation
Circuit Description
The ECM (Engine Control Module) or PCM (Powertrain control module) controls the operation of the radiator fan motor through a relay. The control
module monitors coolant temperature through the engine coolant temperature sensor. Using this input signal, the module controls the coil of the cooling
fan relay to provide optimal cooling fan operation.
