PURPOSE: A device for communication between a drive door module, a power seat ECU(electronic control unit), and a tilt ECU is provided to perform the check of defect by performing a signal needed to the power seat ECU and the tilt ECU with a method of a regular format. CONSTITUTION: A communication device comprises: a CPU to output a control signal to control the whole system; many resistances(R1-R8); condensers(C1-C3); transistors(TR1,TR2); diodes(D1,D2); and a power seat ECU and a tilt ECU transmitting and receiving a control signal and data outputted from the SO1 among control signals of the CPU through resistances(R9-R15,R22), condensers(C4-C6), diodes(D3,D4), and transistors(TR3,TR4), and transmitted and received a control signal and data outputted from the SI1 among control signals of the CPU through resistances(R16-R,21,R23), condensers(C7-C9), diodes(D5,D6), and transistors(TR5,TR6).
