摘要： A second communication circuit (24) of each of solenoid valve modules other than a terminal solenoid valve module (16n) receives a signal from a switching line (42) located in the next-stage solenoid valve module, and the second communication circuit of the terminal solenoid valve module that receives no signal from the switching line transmits a solenoid valve control signal and signals related to diagnostic information of the plurality of solenoid valve modules (161 to 16n) to a communication module (12) via a receiving line (40).
