Circuit Description

The engine control module (ECM)/engine transaxle control module (E/TCM) controls the operation of the radiator fan and the condenser fan. The control module monitors coolant temperature through engine coolant temperature sensor. The module also monitors A/C operation through the A/C ON input, A/C signalinput and A/C pressure switch input.

Using these signal inputs, the module will ground the coil of the appropriate relays to provide optimal fan operation.
