I still trust my eyes over the scanner for intermittent faults
Scanners miss what a good visual inspection catches.

Dealing with a flickering dash light last month. The code reader showed nothing, clean as a whistle. Spotted a frayed wire behind the glove box after poking around. Turns out it was rubbing against a bracket. Scanner probably thought it was a ghost in the machine. Fixed it with some tape and a zip tie, good as new.

Noticing how often the real fix is just some dumb physical thing the computer never sees. My smart thermostat kept losing wifi and the app said everything was fine, turned out the cable was pinched behind the wall plate. We get so used to trusting the digital readout that we forget to check if something is just loose or broken in the real world. It's like the tools are too smart for their own good sometimes, looking for a complex problem when it's just a wire rubbing on metal. Your story totally hits on that gap between what the scanner knows and what your eyes can find. Makes me wonder what else we're missing by staring at a screen instead of just looking at the thing itself.

My buddy had this weird thing with his truck last year. The check engine light would flash randomly, but his code reader showed zero issues. He finally found a loose ground wire under the driver seat, rubbing against a bolt every time someone moved. The whole cluster cut out once while he was driving, scared him half to death. A quick solder and some tape later, it was sorted. Those electrical gremlins are no joke.

Wait, isn't solder and electrical tape a bad combo for a repair like that? The solder can crack from vibration and the tape adhesive dries out. I'd have used a proper crimp connector and some heat shrink. That fix might not last long on a truck seat that's always moving.
