1. An on-vehicle device that is mounted on a vehicle to communicate with a server, the on-vehicle device comprising:
a central processing unit (CPU) that generates first information which is information on a state of a motor mounted on the vehicle by using an output of a sensor mounted on the vehicle, and the first information further includes a voltage value applied to a coil of the motor; and
a wireless communication interface that transmits, to the server, the first information and second information which is information on a state of a second component which is different from the motor, and receives, from the server, a state signal indicating an abnormal state of the motor calculated by the server based on the first information and the second information, and
wherein the server calculates the abnormal state of the motor by further using an atmospheric pressure in addition to the first information and the second information.
