Claims

[Scope of utility model registration request]

Display by a plurality of sensors that detect the operating state of the engine mounted on the vehicle or the state of the vehicle, and a control signal received via the first control means based on the detection signal from at least one of these sensors. and a display means for determining the failure of the plurality of sensors), and is provided with a failure determination means for determining a failure with the plurality of sensors, and based on a determination signal from the failure determination means, the first control means is given priority over the first control means. A fault display device for a vehicle engine, characterized in that a second control means for outputting a fault display signal to the table display means is provided.
