    Abstract: Provided is an onboard load control device and a computer program that can reliably detect and extinguish an arc discharge occurring between a pair of terminals of a connector. Arc discharges are caused in advance between terminals of a connector 2 that relays connection to onboard loads, a wireless detection unit receives electromagnetic waves generated due to the arc discharges, and detects frequency distributions of received intensities, and the detected frequency distributions are stored in a ROM in association with the respective onboard loads. Thereafter, frequency distributions that are acquired by the wireless detection unit chronologically are compared with the frequency distributions stored in the ROM, and the electric current flowing to the onboard load that corresponds to the matching frequency distributions is interrupted.
