The Autel Mercedes 38-pin adapter cable is specifically developed to connect the older, vehicle-specific 38-pin diagnostic connector of Mercedes-Benz to the 16-pin OBD2 connector of a diagnostic device. This adapter cable is used in Mercedes-Benz passenger cars produced before full standardization to OBD2, where the diagnostic port is usually located in the engine compartment rather than inside the cabin.
By implementing the correct pin layout, this adapter enables communication between the complex wiring networks of older Mercedes models and modern diagnostic equipment. The adapter ensures stable signal transmission for various protocols needed to read modules such as engine, transmission, ABS, and airbags via the 38-pin connector. The design features a molded construction that withstands intensive workshop use.
