Isn’t it great how cars just have like random lights that come on whose design is so ambiguous that there’s no possible chance you could work out what they’re trying to indicate.

My car occasionally displays a blue tick, what the hell is that supposed to mean? It only comes up maybe once every 4 or 5 months so it’s really hard to work out a pattern.

Dont you have the manual? I did buy a used car and it had manual

No you dont get it, its bad design if you have to read. Also why are there 3847436189347 different lamps that indicate something now? Thats bad design. Oh why do i not know what the single error lamp means and what exactly is broken?bad design…

All because people dont want to rtfm.

With all the infotainment bullshit they’ve added to cars these days they really could just tell you what the problem is. Still, RTFM.

The challenge there is that there is rightfully an air gap between the infotainment and the actual critical systems to running the car. Sometimes there’s a heavily limited data feed that feeds some data one way but generally the two systems are completely separate and cannot communicate with each other so that you can’t brick your car by loading a malformed music CD for example.

Pay attention the next time you’re futsing with settings and notice how the infotainment is separate from any sensors or settings related to vehicle operation

There’s literally zero reason that system couldn’t pull and display trouble codes from the control module without breaking anything.
