When a predetermined second diagnosis execution condition is met and, moreover, the first diagnosis process is not being executed, the electronic control unit executes a second diagnosis process of diagnosing whether an exhaust gas cleaning filter has a fracture based on measured values of an incoming gas temperature and an outgoing gas temperature.",
