Abstract
Systems and vehicles for determining an operational status of at least one trailer brake are provided. A system for determining an operational status of at least one trailer brake includes machine readable instructions stored in one or more memory modules that, when executed by one or more processors, cause the system to command a trailer brake current output circuit to intermittently supply a diagnostic current to the at least one trailer brake during a trailer brake activation period, receive a sensed current signal from a trailer brake current sensing circuit in response to the command to supply the diagnostic current, and determine the operational status of the at least one trailer brake based on the sensed current signal.
