Abstract
A signal control device includes a charge/discharge circuit, a sampling capacitor, and an AC conversion circuit. The charge/discharge circuit is capable of charging or discharging the sampling capacitor. The AC conversion circuit performs an AD conversion by converting an analog voltage value charged in the sampling capacitor into an AD conversion value that is a digital value. After a charge operation or a discharge operation to the sampling capacitor with the charge/discharge circuit, the AD conversion circuit performs the AD conversion, and a malfunction of the charge/discharge circuit is determined based on a diagnosis result of the AD conversion value.
