1. A system for controlling a trailer brake output circuit, the system comprising:

  • an input device configured to output a signal in response to receiving an input from a user; and

    an electronic control unit communicatively coupled to the input device, the electronic control unit comprising;

    one or more processors;

    one or more memory modules communicatively coupled to the one or more processors;

    the trailer brake output circuit communicatively coupled to the one or more processors, wherein the trailer brake output circuit is configured to output a trailer brake output signal; and

    machine readable instructions stored in the one or more memory modules that cause the electronic control unit to perform at least the following when executed by the one or more processors;

    receive the signal from the input device, the signal being associated with the input from the user;

    limit the trailer brake output signal to a first value when the trailer brake output circuit outputs the trailer brake output signal in response to the signal received from the input device; and

    limit the trailer brake output signal to a second value when the trailer brake output circuit outputs the trailer brake output signal independent of the signal received from the input device, the second value being smaller than the first value.
