The OBDSTAR M015A is an Adapter cable that converts a Honda 4-pin OBD connection to a standard 16-pin OBD2 (J1962) connector. The cable is designed for use in diagnosing Honda outboard motors and boat engines that have a proprietary 4-pin diagnostic port. The Adapter cable is only compatible with OBDSTAR readers and programmers.
The M015A connects the Honda-specific 4-pin port on the engine to the OBD2 input of the connected OBDSTAR device. Through this connection, the diagnostic signals from the engine control unit — including K-line communication — are transmitted to the reader. The cable ensures the correct pin mapping between the unique Honda port layout and the standardized J1962 port, allowing the diagnostic system to correctly read and process engine data.
