PROBLEM TO BE SOLVED: To facilitate fluctuated aftertreatment in an electronic control system having the function of blocking voltage supply from an external power source when the treatment (aftertreatment) to be executed at the time of turning-off of an ignition switch (IGSW) is completed. SOLUTION: A CPU 12a counts up a counter in advance by the number of types of the aftertreatment, and has a counting function 21 for counting down the counter whenever completing the aftertreatment. When turning off the IGSW 5, a main relay 3 is turned off when a counted value of the counter becomes an initial value which is a value before counting up. The CPU 12a is not necessary to individually determine on the basis of the counting function 21 whether or not the aftertreatment is completed when determining whether or not the main relay 3 is turned off. Thus, a structure for determining whether or not the aftertreatment is completed is not necessary to add or delete in response to the fluctuated aftertreatment. COPYRIGHT: (C)2008,JPO&INPIT
