PROBLEM TO BE SOLVED: To provide a control device preferentially storing effective data specifying the cause of a failure and having high importance in a memory. SOLUTION: The control device includes: an SRAM 114 for storing control data stored in a ring buffer 113a; and a microcomputer 103 executing ring buffer processing storing control data successively generated in the ring buffer 113a by ring buffer control, processing determining the abnormality of a predetermined part according to an input signal from an input/output portion 115, a processing storing the control data stored in the ring buffer 113a to the SRAM 114 when the abnormality of the predetermined part is determined, and processing preferentially memory-controlling the control data stored when an abnormality having high importance is determined rather than the control data stored when an abnormality having low importance is determined to the SRAM 114 in the case that the determination of the abnormality is executed several times.
