WARNING: This page is about a different car, the 2004 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.

The ON-OFF control of the radiator fan is performed by the ECM which receives signals from the engine coolant temperature sensor and the vehicle speed sensor.
