The OBDSTAR M085 is an MTU 12-pin to OBD2 16-pin adapter cable designed for diagnostic reading of MTU marine engines in motorboat applications. The cable connects the round 12-pin MTU diagnostic connector on the engine to a standard J1962-compatible OBD2 port, allowing OBDSTAR diagnostic equipment access to the engine system. The connector on the engine side features a cylindrical housing with a locking ring, characteristic of MTU systems in marine environments.

The adapter cable converts the pin configuration of the MTU 12-pin connector to the corresponding pins of the OBD2 16-pin connector, ensuring communication protocols such as CAN-bus or K-line are correctly transmitted to the connected diagnostic device. During use, the OBDSTAR diagnostic equipment reads fault memories, engine parameters, and system data from the MTU engine management system via this cable. The cable is intended exclusively for use with OBDSTAR diagnostic tools or programmers.

ADVANTAGES

✔ Allows direct connection between the MTU 12-pin diagnostic connector and a standard OBD2 port without additional adapters.
✔ The cylindrical locking connector on the engine side ensures a mechanically stable connection, suitable for the marine environment.
✔ Supports CAN-bus and K-line communication, enabling reading of engine parameters and fault memory via OBDSTAR equipment.

KEY POINTS

✕ Only suitable for MTU marine engines with a 12-pin round diagnostic connector; not compatible with other engine types or connectors.
✕ Only compatible with OBDSTAR reading devices or programmers; does not work with diagnostic equipment from other brands.
✕ Application limited to motorboat environments; not intended for diagnostics of road transport or industrial vehicles.

Applications and functionalities

The OBDSTAR M085 Adapter Cable offers the following diagnostic functions when used with compatible OBDSTAR equipment on MTU marine engines:

  • Reading fault memory: Stored fault codes from the MTU engine management system are read through the cable, allowing identification of malfunctions in engine components.
  • Live data monitoring: Real-time engine parameters such as RPM, temperature, and pressure are read and displayed on the connected OBDSTAR device via the CAN-bus or K-line connection.
  • Clearing fault codes: After diagnosis and repair, stored fault codes can be cleared via the OBDSTAR device, with the cable providing the necessary communication link.
  • Marine engine system diagnosis: The cable enables access to the engine system of MTU engines in motorboat applications, specifically via the 12-pin round MTU connector.

Compatible vehicles and applications

The compatibility below is based on available source data. The cable is suitable for motorboat systems equipped with a MTU marine engine with a 12-pin round diagnostic connector.
