Abstract
A system and a method for diagnosing and isolating a power integrator malfunction are herein provided. The system includes a controller for processing inputs from vehicle electronic control units (ECUs) to actuate semiconductor switching elements to further actuate vehicle electrical systems. The switching elements are in connection with the controller and actuated by a low current signal to actuate a high current circuit to drive an electrical load. Additional semiconductor devices are connected the switching devices for the purpose of monitoring overcurrent, overtemperature, and electromagnetic interference conditions that may affect the switching elements. A communications module is provided to send and receive communications relating to conditions affecting the switching elements over a communications bus. A display connected to the communications bus is operable to display conditions affecting the switching elements.
