Appreciation post: An old pilot at the FBO changed how I see fault codes
He told me, 'The box just tells you where to start looking, not what to find,' after I spent a whole shift chasing a phantom ADF fault on a King Air. That simple line flipped a switch for me about trusting the diagnostic process over just the readout. How do you balance what the system tells you with your own troubleshooting gut check?

Learned that lesson the hard way with a false oil pressure warning. Started trusting the gauges and my ears more than the single alert after that. Now the computer message is just one clue in the whole picture.

It's like what @sandrajackson said, that advice is solid for any trade. You gotta treat the fault code like a map pointing to a general area, but you still have to walk the ground yourself. I've seen guys swap a good part because the code said so, when the real issue was a chafed wire two feet away. The box gives you the neighborhood, but you have to find the right house.
