Abstract
A diagnostic system for a power supply having first and second output terminals that output first and second reference voltages, respectively, is provided. The diagnostic system includes a microcontroller having an analog-to-digital converter with first and second banks of channels. The microcontroller samples the first reference voltage at a first sampling rate utilizing a first common channel in the first bank of channels to obtain a first predetermined number of voltage samples. The microcontroller determines a first number of voltage samples in the first predetermined number of voltage samples in which the first reference voltage was outside of a predetermined voltage range. The microcontroller sets a first power supply diagnostic flag equal to a first fault value if the first number of voltage samples is greater than a first threshold number of voltage samples.
