The OBDSTAR M070 connects the 18-pin ECU diagnostic port of Tohatsu outboard motors to the 16-pin OBD2 (J1962)-input of an OBDSTAR device. At the engine end, the cable connects directly to the 18-pin port of the engine control unit.
The pin configuration of the 18-pin Tohatsu-connector differs from the OBD2 layout, which means communication cannot be established without this cable. Both ends are fitted with locking connectors and the cable features a robust shielded body — suitable for marine use. The cable unlocks the diagnostic connection to the outboard motor's engine control unit. Which functions become available thereafter is determined by the software and model of the connected OBDSTAR device; the cable itself does not add any coverage.
KEY BENEFITS
IMPORTANT NOTES
Applications and functionality
Via the 18-pin port, you can access the engine control unit of the outboard motor.
Control units you can reach
- Engine control unit (ECU):The outboard motor control module to which the 18-pin diagnostic port is connected.
- Other modules:Whether additional units on board are accessible varies depending on the installation and device.
What you can do
- Read fault codes:Retrieve stored and active fault codes from the ECU to identify the cause of a malfunction.
- Clear fault codes:Empty the ECU memory after diagnosis is complete and the problem has been resolved.
- View live data stream:Monitor engine parameters such as engine speed, water temperature and fuel pressure in real time.
- Request ECU information:Read data about the engine control unit, including software version and identification numbers, for documentation or verification purposes.
- Please note:Which functions actually work depends on the OBDSTAR device model and the associated software.
Compatible vehicles and applications
The determining factor is the 18-pin ECU connector, not the engine model.OBDSTAR does not provide model years for this cable; compatibility is based on the connector present.
- Tohatsu:Outboard motors with 18-pin ECU connector — consult the OBDSTAR compatibility list for specific engine models and model years.
