Until a vehicle system is activated, a switching circuit (510) outputs a pilot signal (CPLT) to an OR circuit (518). As a result, lowering of the potential of the pilot signal (CPLT) caused by a resistance circuit (520) is avoided, and the pilot signal (CPLT) is provided in a non-pulsed manner. A power supply CPU (530) is activated in accordance with any one of a connector signal (CNCT) and the non-pulsed pilot signal (CPLT). When the vehicle system is activated, the switching circuit (510) switches an output destination of the pilot signal (CPLT) to the resistance circuit (520). |
