PROBLEM TO BE SOLVED: To maintain the same multiplexing control function as that in a normal time even without providing a preliminary control device when failure is caused in some control device. SOLUTION: Failure diagnostic results diagnosed by the diagnosing functions of control devices 2-1 to 2-3 are output to an operation device 3 as failure diagnosis signals 23-1 to 23-3, and the operation device 3 outputs output signals 37-1 to 37-3 to switching circuits 7-1 to 7-3 based on input signals 13-1 to 13-3 from sensors 1-1 to 1-3 and an operation signal 63 and the failure diagnosis signals 23-1 to 23-3, and the operation device 3 outputs switching circuit switching signals 37-11 to 37-31 to the switching circuits 7-1 to 7-3 based on the failure diagnosis signals 23-1 to 23-3, and the switching circuits 7-1 to 7-3 switch output signals 24-1 to 24-3 to output signals 37-1 to 37-3 based on the switching circuit switching signals 37-11 to 37-31.
