Abstract

The utility model discloses a function verification device for an electric control unit of a marine engine. The function verification device comprises a power supply unit, a power supply switch, a T15 switch, a starting switch, a neutral gear switch, an electric control unit joint, an instrument joint, an OBD joint and a prompt unit. During actual use, the electric control unit connector is connected with an electric control unit, the instrument connector is connected with an instrument, the OBD connector is connected with a vehicle-mounted diagnostic system, the power switch, the T15 switch, the starting switch and / or the neutral gear switch are closed according to verification requirements, and the electric control unit operates after receiving signals through the electric control unit connector. The engine electronic control unit outputs corresponding electric signals to the electric control unit connector, the electric control unit connector transmits the corresponding signals to the prompting unit, and the prompting unit gives out corresponding prompts to indicate verification results of the starting function and the pre-oil-supply function of the engine electronic control unit. Therefore, the engine electronic control unit function verification device can verify the function of the engine electronic control unit, and is simple to operate, simple in structure, low in cost and easy to implement.
