Claim Text:
1. An electronic control apparatus capable of being one of nodes connected to a communication line to form a network, the electronic control apparatus comprising: a microcomputer having a transmitting terminal for transmitting data to the communication line and a receiving terminal for receiving data from the communication line, the microcomputer is configured to perform a predetermined shutdown process upon satisfaction of a predetermined shutdown condition; and a power integrated circuit is configured to control a power supply to the microcomputer, the power integrated circuit including a determining section configured to determine whether the communication line is in a recessive state or a dominant state and a timer configured to measure a time period from when the communication line changes from a recessive state to a dominant state, the timer being reset when the communication line changes from the recessive state to the dominant state, the timer starts measuring the time period when the communication line changes from the recessive state to the dominant state, the power integrated circuit is configured to start the power supply when the communication line changes from the recessive state to the dominant state under a condition that the power supply is stopped, the power integrated circuit is configured to stop the power supply when the timer reaches a predetermined threshold value under a condition that the power supply is performed; wherein the microcomputer is configured to, during at least a portion of the predetermined shutdown process, change the communication line from the recessive state to the dominant state, and thereafter changing the communication line from the dominant state back to the recessive state.
