An in-vehicle device having a function of detecting an anomaly in an in-vehicle system and an interface device having an LED for notifying an occupant of a vehicle of an anomaly state are connected via a communication path for transmitting an alternating current signal. The cathode of the LED is connected to the vehicle body ground, and the anode is connected to the communication line of the communication path via the inductor. When the in-vehicle device detects an anomaly in the in-vehicle system, the in-vehicle device notifies the occupant of the vehicle of the anomaly by applying a direct current drive signal to the communication line to drive the LED.
