Yes the main fan is controlled by the DDEC. On the lower left side of your engine, you should see a gold colored manifold with hoses going to the fan motor. The solenoid on that manifold is what changes the speed. When the solenoid fails, the default is to high speed.
By running at high speed all the time, you are giving up about .5 mpg.
