PROBLEM TO BE SOLVED: To suppress deterioration of controllability by an ECU even in an abnormal condition where a self-shutoff function by the ECU is not executed normally.SOLUTION: After an IGSW 5 is turned off, a main microcomputer 21 starts normal IGSW OFF post processing with a main relay 9 being kept ON, and after the normal IGSW OFF post processing is completed, turns off the main relay 9 and stops the operation. After the IGSW 5 is turned off, the main relay 21 also determines whether the condition becomes abnormal where the normal IGSW OFF post processing cannot be executed, and when it is determined that the condition is abnormal, obtains executable time indicating after how much time of turning off of the IGSW 5 the processing can be executed. Subsequently, next time the IGSW 5 turns from ON to OFF again, on the basis of the executable time having been obtained last time, predetermined abnormal time IGSW OFF post processing capable of being completed in the executable time is executed, instead of the execution of the normal IGSW OFF post processing. |
