  If your BMPRO Automobile Accessory shows no light, it might be in 'sleep' mode. Try activating the manual override on the brake controller to wake it up. If there's still no power, check the quality of the power, ground, and brake controller wire connections, as well as any blown fuses on the tow vehicle and trailer. Also, verify the power source voltage is between 12-15V, as over voltage (greater than 20V) or low voltage (less than 3V) can cause this issue. Inspect the quality of power and ground connections.

  If your BMPRO Automobile Accessory is continuously flashing red and green, sway control of the trailer is automatically disabled when driving on rough terrain. The unit should return to normal operation (indicated by a green light) when you're no longer on rough terrain.
