Emission Systems Readiness
Im getting ready to take my truck for an inspection and live in a state where they do emissions testing. I had failed before because I had reloaded the factory tune and forgot about the drive cycle completion before the inspection. Since then I have run the truck everyday for about a month and went to check it on my scanner and it looks like the "heated catalyst" monitor was not available. The truck is a 2011 F350 4wd CC SRW with the 6.2 gas engine. Is this a monitor that should be on, and any thoughts on what might be causing it not to come be on if it is?

The truck is all stock and the stock tune has been back into it for a month. I understand that the cali emissions are more strict. What I am asking is for this year truck what would be the difference in what systems would be on or off. If or when the inspection station calls me I would like to be able to know if they are not familiar with the difference.

if your "TUNE" truly allowed the Stock Tune to return Fully.
the system will take care of its self. and will reports a problem.. it self tests at every start up.. and many retested as it is driven..
some computer flags must have a set number of restarts to remove Flags... so a full reset at day of people test is reported.

" If or when the inspection station calls. "
Never had to test outside of IL so I'm ignorant about this but, WHY???? Does the testing station have your truck?? In IL, we drive up, into a stall, get out, go stand in a little enclosed area and watch the test guy plug into the OBD port, 5 minutes later you either passed or didn't pass, that simple.

Yes they remove gas cap .. connect a hose to gas cap. run test. reattach gas cap to truck.
I understand in a few states.. a repair shop does the Test...

You should be able to locate a driving cycle or series of drives that will try to replicate and satisfy the conditions that the computer will be looking for to reset the monitors for the readiness test. Probably unique to your model/year. Otherwise it could take months to stumble across the various driving conditions needed to be checked by the computer.

Ford equipped these medium duty trucks with a bewildering array of emissions standards. For most vehicles, it is supposed to be pretty easy to know what equipment is on it, for example, a California OBDII vehicle should have EGR and pre and post catalytic O2 sensors. Certain years should also have multiple cats per exhaust bank. However, my CA OBDII truck does not have EGR, but does have pre and post O2 sensors with only one cat. Point is, if the guy testing your emission system is an untrained Jiffy Lube type grunt, he's not going to know there are differences.

The drive cycle readiness is in the manual
some states have private inspection points which are basically repair shops and those repair shops require spots in which you drop yourvehicle off and they call you with the repair estimate to pass inspection( bulbs, brakes, suspension parts, etc)
