Claim:
1. A driving device that is connected between a control unit and an actuator and that drives the actuator through control by the controller, the driving device comprising: a fault detection device that performs one or more fault determinations to determine whether or not a fault occurs in the actuator; a serial interface that communicates with the controller; a memory device that stores a result of the fault determinations and a program executed by a processor via the serial interface; the processor that, according to a fault determination request from the controller, executes the program, and causes the fault detection device to execute the fault determinations; a timer that measures a time limit time for the fault determinations and a determination period for each of the fault determinations; and a counter that counts, during the time limit, a number of times that the fault determinations are executed by the fault detection device, and a number of fault occurrences in the actuator that are detected by the fault detection device, wherein, in response to receiving the fault determination request from the controller, the processor executes the program to cause the fault detection device to execute the fault determinations for the number of times within the time limit and to execute each of the fault determination during the determination period, and after the time limit elapses, transmits the result of the fault determinations to the controller.
