<p>In a voltage monitor, an abnormality detecting unit receives first information outputted from a first obtaining unit and second information outputted from a second obtaining unit, and determines that an abnormality that affects on at least one of first and second diagnostic thresholds arises in the voltage monitor when the first information is different from the second information. The abnormality detecting unit receives a first forced signal outputted from a first forced-output unit and a second forced signal outputted from a second forced-output unit. The abnormality detecting unit determines whether a timing at which the level of the first diagnostic threshold is switched for each step is deviated from a timing at which the level of the second diagnostic threshold is switched for a corresponding step based on a result of a comparison between the first forced signal and the second forced signal.</p> |
