1. A system for controlling a trailer brake output circuit, the system comprising:
an 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 a signal from a vehicle stability control system, the signal indicating that a vehicle stability control flag is set;
generate the trailer brake output signal in response to the vehicle stability control flag being set such that the trailer brake output signal ramps up to a target value over a predefined period of time;
maintain the trailer brake output signal at the target value while the vehicle stability control flag is set; and
output the trailer brake output signal such that the trailer brake output signal ramps down from the target value when the vehicle stability control flag changes from set to not set.
