A method of determining whether an electronic component on a trailer is functioning from within a passenger compartment of a vehicle having an electrical connection with the trailer generally includes determining a first electronic component configuration associated with the trailer and determining an electrical load profile for a terminal in the electrical connection between the vehicle and the trailer based on the first electronic component configuration of the trailer. The method also includes associating the electronic component on the trailer with the electrical load profile for the terminal in the electrical connection and monitoring a value descriptive of an electrical load at the terminal in the electrical connection. The method further includes informing a user in the passenger compartment that the electronic component is not functioning when the value is less than a threshold value.
