This is maintenance magenta line - "feel diif press light" wasn't indicating a fault and wasn't faulty, rather EFS was active for some time which means stick shaker was also, coupled with the reported IAS and ALT disagree should be more than enough to indicate AOA information (not necessarily probe) problem. But the IFIM is obviously not smart enough to work that out, and the spanners were either not smart enough to deviate from it, or were constrained to stick to it. Same goes for trusting the BITE when it said all was ok.
And as for (in another post) why inspect or clean a connector on a brand new aircraft if you were actually thinking rather than doing maintenance-by-numbers - KC46 FOD ring a bell with anyone?
