Working a night shift on a 787 in Seattle showed me why you should never trust a single fault code without checking the whole system first.

Oh man, that's the truth. It's like when a car throws a code for a bad oxygen sensor, but the real problem is a vacuum leak three feet away. The computer just sees the weird reading and guesses. You gotta trace the whole line to find the actual break.

Trace the whole line" seems like overkill sometimes.

Yeah, "the computer just sees the weird reading and guesses" is exactly it. @stella_rodriguez nailed that. I mean, how do you even know where to start looking if you don't follow the whole line? It feels like extra work upfront but it always saves more time later when you find the real spot. Otherwise you're just guessing and swapping parts forever.
