A vehicle system, includes a battery state monitoring module including a battery state monitoring device for measuring a current monitor voltage value that varies according to a current value flowing through a current detecting resistance coupled to power supply terminals of a battery, and an arithmetic circuit that determines a state of the battery based on the current monitor voltage value measured by the battery state monitoring device and transmits the determination result at a request from a high-order system, and a central control unit for outputting an internal ignition signal that directs start and stop of a engine to an electronic load circuit for controlling the engine and a starter, the battery state monitoring device carries out a short-circuit test operation for testing a short circuit state between two external terminals coupled to two ends of the current detecting resistance, and a current monitoring operation of measuring.
