Tell us, how a oil pump failure is made worse, with FADEC?

The software may not be designed to anticipate and react to an
oil-pump failure. The failure may cause the software to follow and
unexpected and unpredicted path, or it may cause a fault in the
software; both can produce catastrophic results.

The error may be one of system design (inadequate specifications), or
one of coding (careless writing or testing of code).

Explain how FADEC could be made to take into account a oil
pump failure, or how not having FADEC makes the oil pump failure
any better of a situation.

I'm not an engine specialist, so I'm not sure how best to deal with an
oil-pump failure.
