Abstract

A diagnostic system for a vehicle electrical system having a first and second diagnostic application is provided. The first diagnostic application commands a high side driver circuit and a low side driver circuit to transition a contactor to an open operational position when a first difference value is greater than a first threshold difference value indicating that at least one of the first and second analog multiplexers is malfunctioning. The second diagnostic application commanding the high side driver circuit and the low side driver circuit to transition the contactor to the open operational position when a second difference value is greater than the first threshold difference value indicating that at least one of the first and second analog multiplexers is malfunctioning.
