Abstract
The present invention provides a boosting system, a diagnosing method and a diagnosing program, that may diagnose a boosting section while suppressing consumption of electric power and current, and without being carrying out by a CPU. Namely, during an initializing operation, difference between power supply voltage and own threshold voltage charges capacitor Cof a comparison circuit, and a difference between voltage of a constant voltage and the own threshold voltage charges capacitor C. In a comparing operation, a boosting section and the capacitor Care connected so that boosted voltage is inputted, and GND and the capacitor Care connected so that GND voltage is inputted. At this time, if output OUT is L level, it is diagnosed that there is no defect, whereas if the output OUT is H level, it is diagnosed that there is defect.
