Yes its' intact.
PIP4864 rev D was done because it had the classic issue of not resetting after a def refill. 4 or 5 weeks later (and 500 miles from home) it decided it needed fluid again, but would only take less than a quart, and would not reset. Found a dealer, and because of knowledge from this site, was able to work with service writer to keep researching in his computer and find PIP4864. (He wanted to follow a procedure that was for a different problem ). Anyway, he agreed PIP4864 was the correct thing to do, and the truck has been trouble free since.
I've had zero troubles since PIP4864 rev F was applied in late spring 2011. I had the 'recall' programming done late in the fall.
The truck has just over 30,000 miles.
