They hooked up to the OBDII and ran a diagnostic tool and it told them exactly where to look and charged you $250.
Honestly, I'm usually fine paying an honest professional a few hundred bucks to do something simple that'd take me a few hundred hours to work out. Time is money.
Obd2 can't find a bare wire. The internet is full of doubting Thomases. It gives people a license to talk about things they've never done.
You're being pedantic. No, OBD2 can't tell you exactly which wire is corroded or shorted, but it can tell you exactly which subsystem is throwing errors or non-standard codes, which tells you where to look for issues.
It's the same as saying eventvwr can't tell you which piece of hardware is failing. Of course it can't, but it will tell you what piece of hardware to look at and test, rather than running every single diagnostic possible in the hopes of finding the fault via the scattergun approach.
In the end there's no substitute for a set of hands and a pair of eyes yes?
