Abstract: A controller is configured to execute an emission process of, on condition that the number of times a leakage diagnosis of a fuel tank is performed in a stop period from when an internal combustion engine stops to when the engine restarts is less than a predetermined allowable number of times, emitting gas from the fuel tank via a canister by opening a shut-off valve, execute a diagnosis process of performing the leakage diagnosis based on a change in index value, caused by the emission process, the index value indicating a pressure in the fuel tank, and execute a subtraction process of, when fuel has been fed to the fuel tank in a state where the shut-off valve is open in the stop period of the internal combustion engine, reducing the allowable number of times in the stop period in which fuel has been fed to the fuel tank.

Abstract: There are provided an electric connection box and a wire harness including: a body including an accommodating portion inside the body, the accommodating portion being configured to accommodate an electronic component. The body includes an electric wire holding portion inside the body, the electric wire holding portion having a slit-shaped groove configured to radially sandwich and hold an electric wire extending from a connector to be connected to the electronic component. The groove of the electric wire holding portion includes: a groove inlet portion; a groove deepest portion; and a narrow portion between the groove inlet portion and the groove deepest portion. A groove width in the narrow portion is narrower than a groove width in the groove inlet portion.
