Hella Gutmann says the associated VCI for mega macs 77, ONE, S 20, 56, 42SE and PC/PC-SE can be used as a PassThru interface; mega macs X itself can also be used as one. The exact hardware, drivers and OEM compatibility must be checked. See mega macs X.
Vehicle coverage, functions, vehicle-maker approval, operating system, driver version, subscriptions and security authorisation must be checked for the exact vehicle and job. Follow the vehicle manufacturer’s programming procedure and specified stable power supply. A J2534 interface does not by itself supply OEM software or guarantee every function.
