SOLENOID MODULE

PROBLEM TO BE SOLVED: To provide a solenoid module for which the allocating position the solenoid module is not appointed in advance in manufacturing vehicle components.SOLUTION: In the solenoid module 10, a solenoid and a drive circuit are integrated. The solenoid module 10 includes a digital input circuit 13 as an interface circuit to which a function identification signal for identifying the function to be allocated is input when mounted on the vehicle component. Thereby, even if a plurality of solenoid modules mounted on the same vehicle component have hardware the same in design, the function allocated to the solenoid module is identified to enable the solenoid module to operate based on the identified function.
