Well maybe not all, but how many out of that 1 model have that maintenance mode? I work on many, none of them have it. Honda, toyota, subaru, vw, even chinese brand like geely, all required a scan tool. The good news? A generic scan tool is enough to set it, doesn't have to be an expensive proprietary tool made just for that specific model that come with those bs. The bad news? Car maker only release it to aftermarket scanner after a few years or so, like the hyundai ionic 5 here.

And even then, like i said, you can just unbolt the motor and turn the piston. 20 years in this industry, this is the first time there's this much drama on basic shit like this.
