Snap-on offers Pass Thru Pro interfaces for workshops using vehicle-maker programming software. The Pass Thru Pro IV is documented by Snap-on as a J2534 reprogramming interface. Confirm generation and software compatibility when buying a used interface.
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.
