Need to know if your Trailer is 2016 or 2017 and has the LCI Sway Command optional system on your trailer. I doubt your trailer is the problem unless you have the Sway Command. The Trailer brakes react to 0 to 12 volts and 12 volts lock up the brakes. NOTHING on the trailer would produce 12 volts unless you are having a problem with the Emergency Brake away switch. So, your TRUCK would be responsible for sending the Lock up Voltage to the trailer. Doug
