摘要：A fuel cut failsafe function monitoring section of a microcomputer sets a fuelcut failsafe function diagnosis period in a period, in which an operation of an engine isstopped (e.g., a period before engine start), and sends a fuel cut failsafe execution

command signal to a fuel cut failsafe execution section of an abnormality monitoringdevice during the fuel cut failsafe function diagnosis period. Thus, the fuel cut failsafeexecution section is caused to output a fuel cut failsafe signal to an injector driver to stopan operation of the injector driver. The fuel cut failsafe function monitoring sectionmonitors an output level of a disablement port of the injector driver at the time, therebyperforming abnormality diagnosis of a fuel cut failsafe function.
