The only time that I've ha the wrench come on is when I had forgot to put my program in the truck and my turbo built up about 40+ psi of boost. Got a strange reaction from the truck, really hard to describe and then it was like in "limp mode". I knew it was because of too much boost though. However, since you said the truck runs fine, I doubt it's that unless I just over reacted about "limp mode".
I wouldn't know where to begine though on this without looking at the codes to see, even if it's just in general, what is going on with the truck.
Find someone with a good CAN scanner that can read more then just the general powertrain module. What would show up on an autozone reader(if anything) might just give you a general indication. Better then nothing, but it could still leave you wondering what it is.
From my one experience with the Wrench light, I would say that it's limp mode til it gets fixed. Could be wrong, but based on my experience, I was in limp mode when it came on for me.
It's not as serious as folk are making it sound; the latest flash uses the "wrench light" to notify the operator of several "out-of-spec" readings that could lead to typical major 6.0L problems. 1-FICM low voltages (FICM Failing), 2-Oil Cooler Efficiency (EGR & Oil Cooler Replacement), & 3-Turbo Overboost (Head Gaskets). If no hard cold starts & you are just driving normally when the light comes on ... suspect the Oil Cooler Efficiency.
If you were not gitting it before the flash, then there's your answer.
Also, I got a fancy CAN enabled code reader ... but it still will not retrieve the disappearing "wrench light" code. It's gotta be stored somewhere ...
