Troubleshooting A Curt Echo Brake Controller That Activates The Brakes When Hazard Lights Flash

Updated 09/18/2023 | Published 09/16/2023

Question:

I tried to use the Curt Echo Wireless Brake Controller today. It does not work with my 2021 Ford Explorer ST. At one point I had my emergency flashers on and the controller was applying the trailer brakes each time the lights flashed. When coming to a stop the breaks would apply, release, apply until I came to a full stop. Its an extremely simple setup, so either the controlled is defective or there is some problem with my Explorer software and the controller software. Please advise.

The Curt Echo Wireless Brake Controller # C51180 has a setting in the app that will prevent the brakes from being applied when the hazard lights are flashing. If you disable the hazard light braking function in the app and it continues to activate then you could have some debris on the either the 7-way cable or port that's allowing the electrical signal to bleed over to the other pin and just needs to be cleaned off.
