Some of the manufacturers let you use a J2534 and PC as scan tool but you must pay a subscription unless you buy OE hacked software online. If I remember correctly a J2534 can be used as dealer level scanner with: GM, BMW, Mini, Jaguar, VW, Audi, Toyota, Lexus, Land Rover, Volvo. Also older versions of Honda HDS (V2.20) can be used with J2534 but you need to edit registry.
