ABSTRACT:
An ECU that controls an engine of a vehicle includes a MPU and an IC that monitors the operation of the MPU. The MPU is programmed to execute a verification result check and test selection function for selecting a test for verifying the function of the MPU. The MPU runs the selected test, and transmits a test result indicating the result of the test to the IC. The IC checks whether the test result from the MPU is correct or incorrect, and transmits a verification result to the MPU.
