A communication device includes a first resistance circuit (RB) connected between an output of a signal generating unit (602) and a first terminal (TS1) and having a resistance value corresponding to a requested operation mode requested to a vehicle. The vehicle (10) includes: a second resistance circuit (RA) connected between a ground node (512) fed with a reference potential and a second terminal (TS2); and a vehicle control unit (508) for setting an operation mode of the vehicle. The vehicle control unit (508) detects a signal potential of a signal (CPLT) via a first signal extraction node (N1) provided on a path connecting the second terminal (TS2) and a second resistance circuit (RA) to each other, and sets the operation mode of the vehicle (10) at the requested operation mode corresponding to the resistance value of the first resistance circuit (RB).
