    a starter driving unit configured to drive a starter for restarting the engine;

    a test unit configured to perform a failure test of the starter driving unit to determine whether the starter driving unit is out of order before the control unit stops the engine by the eco-run control;

    a nullifying unit configured to nullify the failure test by the test unit when it is detected that a power supply voltage supplied to the starter driving unit drops below a predetermined value; and

    a prohibiting unit configured to prohibit the control unit from performing the eco-run control when the test unit determines that the starter driving unit is out of order,wherein the prohibiting unit prohibits the control unit from performing the eco-run control in a case where the nullifying unit nullifies the failure test by the test unit during a test period in which the test unit performs the failure test.
