The Autel adapter cable is an adapter that establishes a connection between a vehicle with a 38-pin OBD1 diagnostic port and a 16-pin OBD2 reader device. This cable is specifically designed for older Mercedes-Benz models that are not yet equipped with the standardized OBD2 port.
The adapter functions as a physical converter of the pin configuration, allowing modern diagnostic testers to communicate with the vehicle's control units. This makes it possible to perform diagnostic functions, such as reading fault codes and viewing sensor data, on compatible models that use the older, round diagnostic connector.
Application and functionality:
This adapter cable is designed to establish a communication link between the specific 38-pin diagnostic port of Mercedes-Benz and a universal 16-pin OBD2 diagnostic device.
- Diagnostic connection: Enables communication with the vehicle's various control units for reading and clearing fault codes.
- Compatibility: Ensures that modern OBD2 scan tools, including those from Autel, can be used on older Mercedes-Benz vehicles.
- Passive adapter: The cable functions as a physical pin-to-pin adapter and contains no active electronics or software. The functionality depends on the capabilities of the connected diagnostic device.
Compatible vehicles and applications:
This adapter cable is specifically developed for older Mercedes-Benz passenger cars and light commercial vehicles equipped with the round 38-pin diagnostic connector. This generally concerns models from before approximately 2001.
