Abstract
A diagnostic system for diagnosing faults in a trailer electrical system generally includes a mode determination module that determines a current operating mode to be one of a sleep mode, a normal mode, a situational awareness mode, and an adaptive calibration mode. A first mode module operates when the current operating mode is the normal mode and during operation, diagnoses an open circuit fault of the trailer electrical system based on a comparison of a current load on the trailer electrical system and an average load.
