Abstract

A diagnostic system for a vehicle electrical system having first and second voltage regulators outputting first and second voltages, respectively, is provided. The diagnostic system includes a microcontroller having an analog-to-digital converter, a first application, and a first diagnostic handler application. The first application sets a first analog-to-digital converter status flag equal to a first fault value when a difference between a first corrected voltage value and a second corrected voltage value is greater than a threshold difference value indicating that the analog-to-digital converter is malfunctioning. The first diagnostic handler application commanding a digital input-output device to generate control signals if the first analog-to-digital converter status flag is equal to the first fault value.
