Abstract
A diagnostic system includes a microcontroller having a first A/D converter, first and second applications, and a first analog multiplexer electrically between a first voltage regulator and the first A/D converter. The first application sets a first overvoltage diagnostic flag to a first fault value if a first voltage of the first voltage regulator that is measured by the first A/D converter is greater than a first voltage, and in response further transitions a contactor to an open operational state. The second application sets a second overvoltage diagnostic flag to a second fault value if a second voltage of the first voltage regulator that is measured by the first A/D converter is greater than a second voltage, and in response further transitions the contactor to the open operational state.
