| description | Provided is a motor control device capable of identifying a cause of an abnormality in communication between a plurality of control circuits. A first microcomputer (21) is configured to identify the cause (a content of the abnormality) of a communication abnormality based on a combination of whether communication through a first communication line (41) is established, whether communication through a second communication line (42) is established, and whether a second clock (SCL2) is normal. Specifically, the first microcomputer (21) separately determines whether the communication abnormality between the first microcomputer (21) and a second microcomputer (31) is simply due to an abnormality in the first communication line (41) and the second communication line (42), or due to stop of a function of the second microcomputer (31). The second microcomputer (31) is configured to identify the cause of the communication abnormality based on a combination of whether the communication through the first communication line (41) is established, whether the communication through the second communication line (42) is established, and whether a first clock (SCL1) is normal. |
