The OBDSTAR M081 connects the round 8-pin diagnostic connector of MAN marine engines to the 16-pin OBD2 side of your OBDSTAR device. The connector is located on the engine, in the vessel's engine compartment. The cable comes as standard with the MarineMaster C+D and A+B+C+D.
MAN marine engines do not have a standard OBD2 port. With this cable you can reach the engine control module to read fault codes and view live data. Which functions work is determined by the OBDSTAR software for each engine type.
