<p><P>PROBLEM TO BE SOLVED: To provide an electronic control device that is rewritable of a program at high speed by occupying a communication network without setting up a complex configuration of other electronic control devices connected to the communication network, and to provide a program rewriting system including the electronic control device. <P>SOLUTION: The electronic control device includes: a maintenance switch SW; a manipulation input detector 11a for detecting an input of behavior start manipulation to the maintenance switch SW; a power source detector 11b for detecting that electrical power is delivered only from a maintenance power source supply line that is laid separately from a main power source supply line of a vehicle; and a state transition device 11c for causing the behavior state of the electronic control device to transit to a program rewritable state when the power source detector 11b detects that the electrical power is delivered only from the maintenance power source supply line and also the manipulation input detector 11a detects the input of behavior start manipulation. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
