There is no specific task list in the workshop manual. I had cars and motorcycles of various brands and, except for Mazda, nobody has a good list, while Mazda pretends to have one. Even in good car shops, brand or no brand, including the one owned by my family, there is no official list for a "good check", they just ask you: "what do you want checked?". Why? Because if you ask them to check everything, like Mazda says it does, it will cost a lot for little benefits. And car shops will be happy to charge labor for "checks".

The best checks I get is when I ask my cousin (owner of a car shop, certified to do inspections): "take my car for a couple of days as your daily driver, if you notice anything wrong then fix it". Otherwise the official testing includes: suspension and direction (includes indirectly wheel bearing), brakes, emissions, headlight alignment, rust or corrosion signs, tire integrity and wear vs indicator, brake fluid level, antifreeze level, washer fluid level, signs of fluid leakage in the engine compartment or at wheels. That's it.

I read the instruction manuals from all my cars and motorcycles. They are a minimum, in my opinion, I check myself a lot more, regularly.

Funny, the workshop manual, true it is a single one from the 80s, has quite detailed interval tasks listed. And the detailed instructions later, identified by task code. On top of that, it includes all / most steps regarding diagnostics. And, obviously, detailed instructions regarding repair and replacement of bits and pieces. I never bothered checking those manuals for modern cars so, first I don't do that work and second there is only so much one can do anyway.

The right to repair move started because lately it is difficult to impossible to perform some repairs by yourself and there is a lack of documentation accessible to owners. Yes, in the '80 you got specifications, manuals and guides for most cars, almost none today.
