These vehicles, produced before the introduction of the European OBD2 standard, use a \u003cstrong\u003ebrand-specific round 38-pin diagnostic connector\u003c\/strong\u003e. The Adapter features a \u003cstrong\u003emale 38-pin plug\u003c\/strong\u003e and a \u003cstrong\u003efemale 16-pin J1962 port\u003c\/strong\u003e, connected by a short and flexible cable guide that reduces mechanical stress on the vehicle port during diagnostics.\n\u003c\/p\u003e\n\n\u003cp\u003e\nWhen connected, the adapter cable functions as a \u003cstrong\u003epassive bridge\u003c\/strong\u003e that physically converts the pin-out of the older Mercedes system to the standardized 16-pin layout. It passes the necessary \u003cstrong\u003epower, ground, and K-line communication signals\u003c\/strong\u003e to the connected tester. Since the original 38-pin system uses \u003cstrong\u003eseparate communication lines\u003c\/strong\u003e for different control units, the level of system access depends on the internal wiring of the Adapter and the \u003cstrong\u003emultiplex functionality\u003c\/strong\u003e of the diagnostic tool used. This allows the technician to read protocols without manually bridging pins.\n\u003c\/p\u003e\n\n\u003c\/div\u003e\n\n\u003cdiv style=\"display:flex; flex-wrap:wrap; gap:20px; margin-bottom:40px; align-items:stretch;\"\u003e\n\n\u003cdiv style=\"flex:1;
