If not:

Cold soak the vehicle for 8 hours
· No DTCs present except for P1000
· Fuel fill between 15% & 85 %
Driving Procedure
1) Start the vehicle and idle for four (4) minutes.
2) Idle the vehicle in drive for 40 seconds.
3) Accelerate to 45 mph, using ¼ to ½ throttle.
4) Drive with a steady throttle at 45 mph for 30 seconds.
5) Stop the vehicle and idle in drive or neutral for 40 seconds.
6) Drive at speeds between 25 and 45 mph for 15 minutes.
Use ¼ to ½ throttle accelerations. Include the following conditions:
· At least 5 stops with ten seconds of idle time.
· At least 3 steady speed sections of 1 ½ minutes duration.
7) Drive the vehicle between 45 and 60 mph for 8 minutes.

I have an '11 Lariat. I don't know what you have. This is from my owners manual:
It Says,
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.

It will take several days to do this. Do a driving cycle one day then shut the truck off. Let it sit over night without starting again. Then the next day do another cycle, shut it off, let it sit over night. The next morning (third day) just turn the key on "without" starting the truck. Wait the 15 seconds and watch the check engine light. If it does NOT flash you are good to go. If it does flash the eight times you will need to do another driving cycle and wait overnight again, then check it the next morning.....Again. It actually took me a full week of driving and almost 300 miles.

 

Unless you have a COMPELLING need to do it now, just drive it normally.

It does help if you explain what you have and what you are trying to accomplish.

 

What indicates that your truck is not ready? Do you have a P1000 code?

There are instructions online. GLC has already posted what you need to follow.

It's not that complicated. Most people don't even know if their car is I/M Ready or not. The procedure is designed so that the average person, who does not have a clue, can simply drive their car and the computer will do the rest. It's passive. Unless you feel the need to try to do everything as described. Every time I disconnected my battery, for whatever reason, I simply drove the truck. For me, within days, the computer will have cleared the code. Just normal driving should allow completing the drive cycle.
