1. An electric power source apparatus comprising a turning control apparatus and an auxiliary control apparatus that are disposed in a vehicle, wherein:
the vehicle includes
a main electric power source,
an auxiliary electric power source configured to store electric power that is supplied to the auxiliary electric power source from the main electric power source, and
a supply path configured to supply electric power from the main electric power source to a turning motor that turns a turning wheel of the vehicle, and configured to be opened or closed depending on a state of a start-up switch of the vehicle;
the turning control apparatus is configured to control a control amount of the turning motor disposed in the vehicle, using one of the main electric power source and the auxiliary electric power source as an electric power source;
the auxiliary control apparatus is configured to control a state of the auxiliary electric power source;
the turning control apparatus and the auxiliary control apparatus are configured to communicate with each other; and
the turning control apparatus is (i) configured to stay in a state in which the turning control apparatus can start to communicate with the auxiliary control apparatus even when the auxiliary control apparatus is being reset which causes communication to be disrupted between the turning control apparatus and the auxiliary control apparatus, and (ii) configured to execute communication with the auxiliary control apparatus after the auxiliary control apparatus recovers from the reset.
