Abstract
A leakage determination process determines whether there is fuel leakage from a fuel supply system on condition that a start switch of an internal combustion engine has been turned on. A start estimation process estimates whether there is a possibility of a start operation before the start switch is turned on. Processing circuitry does not execute the fuel injection through the fuel injection process if the leakage determination process has not been completed in a case in which the start switch has already been turned on. The processing circuitry starts the leakage determination process when the start estimation process estimates that there is the possibility of a start operation even if the start switch is not turned on.
