Circuit Description

The ECM (Engine Control Module) or PCM(Powertrain

control module)controls the operation of the radiator

fan motor and the condenser fan motor. The control

module monitors coolant temperature through the

engine coolant temperature sensor.

The module also monitors A/C operation through the A/C

switch ON input and A/C pressure switch input. Using

these input signals, the module controls the coil of the

appropriate relays (condenser fan relays and radiator

fan relay) to provide optimal cooling fan operation.
