PSA: My stubborn refusal to use a diagnostic scanner cost me a weekend

I now plug it in first thing for any electrical issue.

Oof, that's rough! What was the specific fault the scanner flagged that you'd been chasing blindly? I've definitely been there, convinced it was a bad relay only to find out it was a sensor reading WAY out of range. How many hours did you sink into it before caving? The modern stuff is just IMPOSSIBLE without proper tools, right? Like, did you have a moment of pure defeat when the code finally popped up?

Modern electronics will absolutely humble you every single time. That scanner probably flagged something ridiculously simple like a throttle position sensor reading 0% at full throttle, or a wheel speed sensor dropping out at 3 mph. Spent probably four hours swapping known-good parts from another truck before the defeat washed over me. The real lesson is always check the damn basics first, even when you're sure it's something complicated.

Caved and scanned it, was just a dirty connector.
