There is a significant nuance that confuses many people. Ross-Tech does manufacture interfaces that support the J2534 standard.
If you own a legitimate HEX-NET and want to use it as a J2534 pass-thru for VAG ODIS, follow these steps:
perform full ECU software flashing or component protection removal. J2534 (Pass-Thru)
: Install the official drivers for your specific passthru hardware (e.g., Bosch or Autologic drivers).
If you need to perform official flashing, you generally must use a dedicated J2534 interface like the Mongoose-Plus VW2
However, this works in the of what most users hope for.
A J2534 device acts as a "dumb pipe." It doesn’t know anything about the car; it simply takes messages from a software application (usually supplied by the OEM, like Ford or GM) and passes them through to the vehicle’s computer. It is a generic bridge between a PC and a car’s CAN bus.
