Can reflash cause FICM to go out ?

Heres a short history of my 2003 F-350 6.0, 96000 miles.Oil cooler replaced first, then IPC sensor and IPC harness and Y-Pipe and reflash.After 80 miles no power at cold start again. Took truck back to dealer and after 2 days they called me and said FICM is going out. My question is can a reflash cause the FICM to go out ?

Actually there is some debate about that. Some techs that I know say yes it can and do not recomend doing the flashes. Others say it isn't possible.
Personally I have never had it happen nor have I seen any "Official" word on the subject.

Thanks for the replies. It just seems odd that FICM went out right after IPC sensor and harness and reflash. maybe FICM was the problem all along.

How do you not flash a FICM? From what I've read, the new ones don't come programmed.

I recently had a no start issue, long story short my tech(side work) found that he could not get any feedback from FICM. What he found was that somehow ficm lost all its programming, and when he flashed it again with factory parameters its purred ever since. It was wierd, but he advised not installing and uninstalling tunes a bunch, he suspected that could have been one cause.
