The cable uses a standard \u003cstrong\u003eOBD2 connector\u003c\/strong\u003e (16-pin) on the vehicle side and a USB-A connection for communication with an external laptop or PC. This interface is equipped with a built-in physical toggle switch, allowing the system to hardware-switch between the different CAN bus networks used by the vehicle manufacturer, specifically aimed at diagnostics, coding, and programming.\n\u003c\/p\u003e\n\n\u003cp\u003e\nWithin the vehicle network, the interface cable functions as the serial bridge between the vehicle modules and external diagnostic software. Thanks to the \u003cstrong\u003eHS\/MS-CAN switch\u003c\/strong\u003e, the user can manually redirect data communication between High-Speed CAN (standard on pins 6 and 14) and Medium-Speed CAN (rerouted to pins 3 and 11). This allows the internal \u003cstrong\u003eCH340 chip\u003c\/strong\u003e to process data streams from control units that are beyond the reach of regular diagnostic equipment, such as comfort, audio, and body modules. When the software requires a protocol change, the switch is toggled to directly and safely intervene on the selected subnet, enabling precise parameter adjustments.\n\u003c\/p\u003e\n\n\u003c\/div\u003e\n\n\u003cdiv style=\"display:flex;
