摘要： On-vehicle electrical loads (121,122) are connected to an on-vehicle battery (101) via a series circuit including a load switching element (221,222) and a reverse current interrupting element (200a) for a load circuit, and a feeding switching element (120A) that is closed in response to closure of a power supply switch (110). The element (FET) (200a) is closed when the switch (110) is closed and a power supply voltage is applied to a load power supply terminal (Vba) connected to the element (120A), to thereby be energized in an energization direction of an internal parasitic diode thereof. The element (200a) is de-energized when the switch (110) is opened. Thus, malfunction is prevented, which occurs when the element (120A) is opened, a short-to-power flows backward via the element (200a) into the terminal (Vba) so as to feed power to another device connected to the element (200a).

摘要： Even when parts having individual differences among identical parts or differences in deterioration speed between parts, or a part that does not have a non-volatile memory such as an EEPROM in a chip of the part itself, are mixed, there is no deterioration diagnosis device that can appropriately diagnose a state of deterioration due to temporal change or the like, because of which a mechanism (correction methodology) for evaluating and correcting deterioration in the precision or performance of an electronic part that has low precision or considerable temporal deterioration, and does not have a correction function, is incorporated in a deterioration diagnosis device, and a deterioration state is diagnosed using incorporated deterioration determination means when using a product after shipping.
