An automobile includes a fan configured to send cooling air, a fan driving apparatus, a first electronic control unit, and a second electronic control unit. The first electronic control unit is configured to output a first driving control signal to the fan driving apparatus when an ignition switch is turned off and a predetermined condition is established. The second electronic control unit is configured to determine whether or not the first driving control signal has been output by monitoring the signal line when the ignition switch is turned off. The second electronic control unit is configured to output a second driving control signal to the fan driving apparatus when determination is made that the first driving control signal has not been output to the fan driving apparatus from the first electronic control unit, the ignition switch is turned off, and the predetermined condition is established.
