Since the Autowbrake Electric Brake Controller # 3430001 ties into the turn signals it's most likely thinking the signal for the turn signal is actually the stop signal and is activating the brakes. Since there really isn't any troubleshooting that can be done with the unit itself the only thing you can check is the wiring. The first thing to start with is the ground wire to ensure you have a strong corrosion-free connection to the trailer frame. A bad ground can cause all sorts of issues with electronics.

From there you'll check each wire connection to ensure that they're going to the correct wires on the trailer and that there's no loose or corroded connections. If that doesn't work then the unit itself might be faulty and in need of replacement.
