De website lists which vehicle models it supports. >From the description it sounds like a reverse engineered TechStream, which is what all Toyota shops use. Since a hacked version of techstream is free with the purchase of an OBD adapter, you can even download it, for private persons there is no motivation to buy a different tool, since Toyota is not going to enforce against an owner who wants to diagnose their own car with hacked TechStream. Only for businesses that are independent, it might make sense to buy a tool that does not give yhem conflict with Toyota. Cor.
