Abstract: PURPOSE:To cope with the abnormality of a microcomputer by resetting the microcomputer when the prescribed data is not outputted from the microcomputer at the prescribed time intervals. CONSTITUTION:The runaway check data is set to an accumulator when an internal interruption timer which sends said check data at the prescribed intervals counts up the value larger than a prescribed level. The contents of the accumulator are stored in a data buffer as long as an interruption request flag is set at '1' and then set to a transmission buffer to be sent to a microcomputer set at the remote side. The abnormality of the microcomputer of the remote side is decided by an interruption and based on the runaway check data carried out by a main microcomputer 1 and a sub-microcomputer 2. Then the abnormality is decided since the runaway check data of this time is received within a prescribed time from the reception of the preceding runaway check data as long as the contents of a reception buffer are equal to the runaway check data and the value of the internal interruption timer is smaller than a prescribed level.
