Abstract: Provided is an electronic control unit capable of performing fault diagnosis of a watchdog timer circuit without delaying start of typical processing of a computer. A microcomputer termination processing unit 200 stops outputting a pulse to a watchdog timer circuit 101 in response to execution of termination processing of a microcomputer 100. When a reset signal is not output from the watchdog timer circuit 101 even when a predetermined time has elapsed since the stop of the output of the pulse, a watchdog timer circuit fault diagnosis unit 201 writes abnormality information indicating that an abnormality has occurred in the watchdog timer circuit 101 into the nonvolatile memory 102.

Abstract: Appropriate detection of an abnormality of voltage information, which is a basis for correcting a fuel injection amount, becomes possible. For this reason, a fuel injection control device 127, which has a drive IC 208 controlling a fuel injection drive unit 207a to supply a high voltage to a solenoid 405 so as to open a fuel injection valve 105 and controlling the fuel injection drive unit 207a to supply a low voltage to the solenoid 405 so as to hold a valve-open state of the fuel injection valve 105, includes: a drive voltage input unit 211 that measures and outputs voltage information based on an upstream voltage of the solenoid 405 of the fuel injection valve 105 and a downstream voltage of the solenoid 405; a fuel injection amount correction unit 213 that corrects a fuel injection amount of the fuel injection valve 105 based on the voltage information output from the drive voltage input unit 211; and a voltage input function abnormality detection unit 212 that detects whether an output of the drive voltage input unit 211 is abnormal based on the voltage information output from the drive voltage input unit 211.
