I hate when people say that you can't work on vehicles anymore in 2025/2026 because everything is electronics

THEN JUST CHANGE THE WHOLE MODULE.

Also I mean it's not like everything is electronic. Pulleys go bad. Bearings need to be changed. Shocks have to be maintained.

Also you can actually go pretty far with just a multimeter. So far in fact that I have never had an issue with vehicle electronics stopping me from doing what I needed to do and I was a mechanic for 8 years.
