Abstract
A first microcomputer 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 is established, whether communication through a second communication line is established, and whether a second clock is normal. Specifically, the first microcomputer separately determines whether the communication abnormality between the first microcomputer and a second microcomputer is simply due to an abnormality in the first communication line and the second communication line, or due to stop of a function of the second microcomputer. The second microcomputer is configured to identify the cause of the communication abnormality based on a combination of whether the communication through the first communication line is established, whether the communication through the second communication line is established, and whether a first clock is normal.
