The Adapter Cable is designed to establish a connection between older Mercedes-Benz passenger cars and modern diagnostic equipment. The cable features a specific 38-pin OBD1 male connector on the vehicle side and a standardized 16-pin J1962 (OBD2) female connector on the adapter side. This makes it possible to read vehicles equipped with the older 38-pin diagnostic port using a common OBD2 reader.
This adapter functions as a physical bridge that converts the pin configuration of the OBD1 port to the OBD2 standard. This allows a diagnostic device to communicate with the vehicle's various control units, such as the Engine Control Unit (ECU). Using this cable enables reading fault codes, viewing live data, and performing other diagnostic functions on compatible older models without the need for specialized OBD1 equipment.
Application and functionality:
The adapter is developed for performing vehicle diagnostics on Mercedes-Benz models that are not equipped with the standard 16-pin OBD2 port.
- Diagnosis of older models: Enables performing diagnostics on Mercedes-Benz vehicles with a 38-pin OBD1 connection using a modern 16-pin OBD2 reader.
- Connectivity: Forms a stable physical connection between the specific vehicle connection and the standardized interface of the diagnostic device.
- Access to vehicle data: Provides access to diagnostic trouble codes (DTCs) and other system data from the supported control units in the vehicle.
Compatible vehicles and Application:
This Adapter Cable is compatible with various older Mercedes-Benz passenger cars equipped with a 38-pin diagnostic port. These are generally models produced before the year 2001.
