Abstract
A microprocessorcontrols an electrical load groupresponsive to content of a non-volatile program memoryand operation state of an input sensor groupA monitoring control circuit sectionsequentially transmits a large number of question items with an inquiry packet, and compares response content from the microprocessorwith correct answer information to carry out an error determination. The microprocessordiagnoses an interval of receiving an inquiry packet to monitor in reverse the monitoring operation of the monitoring control circuit section. Thus, in an electronic control unit having a microprocessor built-in, a monitoring control circuit is obtained that alternatively executes at regular intervals a part of control programs to carry out operation inspection during operation.
