When I’ve queried DTC using a cheap scan tool it’s usually resolved the important (as in emission relevant) DTC information text and most of the non engine stuff. In order to create a DTC there usually is a customer recognisable fault or an implication for emissions performance.
Many of the DTC are spurious and would only serve to confuse the user. As a system integrator, I’m personally responsible for creating tens of thousands of spurious DTC (in a vehicle population of ~100k) and I have to periodically report to management what has been done to reduce that number. The funny bit is when I found the root cause the management completely lost interest in solving the problem because, money 😂
I’m with you though, there’s no such thing as too much information. I want to know how my car is doing and fix the problems. Most people in the business do not care and our users are ignorant and apathetic, that’s why we can’t have nice things.
Pleased to meet you. I am also one of those people. We’re a rare breed 😂
