Abstract
A control circuitdetermines whether a difference between an input/output potential difference Vand an input/output potential difference Vwhen bypass switches SWand SWare again turned on is equal to or smaller than a threshold value Vthin a case where the control circuitdetermines, at normal times other than an engine restart after being idle-stopped, that a difference between the input/output potential difference Vof a bypass circuit when the bypass switches SWand SWare turned on and an input/output potential difference Vwhen the bypass switch SWis turned on and the bypass switch SWis turned off is equal to or larger than a threshold value Vthand that the bypass switch SWhas an open fault, and validates the determination of the open fault of the bypass switch SWin a case where the control circuitdetermines that the difference between the input/output potential differences Vand Vis equal to or smaller than a the threshold value Vth
