ルセーフ回路。 A large number of electrical components of an automobile are divided into two or more groups, and the electrical components belonging to each group are connected to each control station provided corresponding to each group, and each control station can cooperate with each other. In an automobile electrical component control system connected by a transmission path, one of the control stations is a master station, the other is a remote station, and the remote stations can directly communicate with each other using control signals from the master station. an abnormality determination circuit that includes direct communication instruction means capable of outputting a direct communication instruction signal for instructing to the transmission line, monitors the output line of the CPU of the master station, and determines whether there is an abnormality in the signal of the output line; When it is determined that
A fail-safe circuit for an automobile electrical component control system, characterized in that a safety circuit is provided for transmitting a signal for stopping transmission from the direct communication instructing means and outputting a direct communication instructing signal to a transmission line. .
