From the Owners manual Printing 3 (.pdf) page 391 under Maintenance and Specifications on the Ford Owners Website
I got this from my 2010 1/2 owners manual.
You can check your year, but it should be the same.
I've flashed back and forth numerous times now over 2 1/2 years and never really followed the complete drive cycle thing.
I do the battery disconnect, I do let it idle before driving and take it easy for a while trying not to drive erratically, the first day or two.
The PCM is always learning so eventually it will get there.
Readiness for Inspection/Maintenance (I/M) testing
Some state/provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration. Your vehicle may not pass the I/M
test if the service engine soon indicator is on or not working
properly (bulb is burned out), or if the OBD-II system has determined
that some of the emission control systems have not been properly
checked. In this case, the vehicle is considered not ready for I/M testing.
If the service engine soon indicator is on or the bulb does not
work, the vehicle may need to be serviced. Refer to On-board
diagnostics (OBD-II) in this chapter.
If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position
for 15 seconds without cranking the engine. If the service engine
soon indicator blinks eight times, it means that the vehicle is not
ready for I/M testing; if the service engine soon indicator stays on
solid, it means that the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days.
If the vehicle is not ready for I/M testing,
the following driving cycle consisting of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by 20 minutes of stop-and-go driving,
with at least four 30-second idle periods.
Allow the vehicle to sit for at least eight hours without starting the engine.
Then, start the engine and complete the above driving cycle.
The engine must warm up to its normal operating temperature.
Once started, do not turn off the engine until the above driving cycle is complete.
If the vehicle is still not ready for I/M testing, the above driving cycle will have to be repeated.
