Abstract: An electronic control unit includes a computer that outputs a monitoring signal and an external monitoring circuit that monitors a state of the computer based on the monitoring signal. The computer includes a monitoring signal output section that generates and outputs the monitoring signal to the external monitoring circuit by performing a software process; a self-diagnostic section that self-diagnoses the computer and detects an abnormality by identifying a cause of the abnormality; and a break signal output section that outputs a break signal to interrupt an input of the monitoring signal to the external monitoring circuit by performing a hardware process when an abnormality in the monitoring signal output section is detected.
