Yep.
Yep, again…
So there is a learning curve. Flatter for some, steeper for others. Which begins, of course since it is DMS, with knowing it exists and then finding it.
If one has easy access to an Oreilly’s or Autozone, it is the simple, quick way for anyone of any skill or aptitude to figure out if there is an active code. Note that just because their OBDII reader doesn’t find an issue/code doesn’t mean there isn’t an issue that a better unit with make/model specific settings might find.
That said, if one plans to do more in-depth stuff with their car here, spending an hour or two getting familiar with the Autel and how to get detailed info for one’s specific make and model can’t hurt. There’s a manual/guide here for interested parties:

@Raymond’s point above is a good one. And note that almost every make/model combination has a dedicated forum or two on the internet. Definitely a good idea to find one and register and ask specific questions there.
