ABSTRACT:
A P-ECU determines whether or not energization to an actuator is shut off when a shift-range switch instruction is unissued. If energization to the actuator is shut off, the P-ECU obtains a current rotational position of the actuator according to a count value obtained by an encoder. If a difference between a target rotational position and the current rotational position exceeds a predetermined amount, positional correction control is exercised.
