CURT ECHO® Mobile Brake Controller Installation Manual

Before You Begin

WARNING: Read and follow installation manual carefully. Failure to do so could result in damage to the brake controller unit, loss of trailer brakes or poor brake performance.

• The vehicle must have +12V, ground and turn signals connected to the 7-way socket. Brake output to the 7-way socket is not required.
• See 'Vehicle-Specific Requirements'.
• An existing aftermarket or factory brake controller will not function if Echo® brake controller is installed.
• No special wiring or connectors are required for use.
• OneControl® apps ARE NOT compatible with Apple CarPlay or Android Auto. However, it will not interfere with these features.
• Echo® is designed to provide a Bluetooth connection, without obstruction, up to 50 ft. Connection may also be limited by the Bluetooth signal of your phone.

WARNING: Avoid distracted driving. Only make adjustments when the vehicle is stationary. Please adhere to all applicable traffic laws and motor vehicle safety regulations including, but not limited to, all laws and regulations prohibiting the use of handheld devices while operating a motor vehicle.

WARNING: OneControl® App must be operating in the foreground of your cell phone applications. Operating the App in the background of your cell phone applications may cause delays in braking response when using the manual override button.

WARNING: Do not mount the Echo® near the exhaust pipe. Failure to do so may result in heat damage, loss of functionality and risk of fire.

NOTICE: Prior to driving, test all trailer lights while the trailer is plugged into the Echo®.

Vehicle-Specific Requirements

NOTICE: If your vehicle comes with a trailering app or towing prep package, it may be necessary to activate a tow / haul mode using a push button or in-dash screen menu. This allows power at the 7-way connector of the vehicle. See the vehicle owner's manual to enable this feature.

• The Echo brake controller uses the 7-way connector's +12V connection to power the brakes, and it shares this power with the trailer. Ensure the fuse for this connection is rated for 30 amps. See the vehicle owner's manual to determine the fuse location.
• If the LED on the Echo does not light when plugged into the 7-way connector, the +12V power pin may not have power from the vehicle. Visit a CURT authorized installer to install a power wire to the battery.
• If the phone application cannot connect to the Echo due to an incorrect or missing PIN, contact CURT Product Support. They will need the serial number located on the label of your Echo brake controller.
• Clean and store the Echo in a safe, dry place when not in use. We recommend applying dielectric grease to the terminals.

Some vehicles may require a trailer to be connected to detect a load and activate the +12V power. Consult the vehicle owner's manual for vehicle-specific details or contact CURT Product Support if you are having trouble diagnosing the issue. Known vehicle-specific requirements are listed below:

Ford F-150 (2018 to Current)

• Requires tow / haul mode activation and / or load detection on 7-way before the +12V output is activated on the 7-way connector. Activate tow mode and connect trailer before attempting Bluetooth connection to the Echo. The LED on the Echo must be on.

Ford F-150 (15 - 17)

• These vehicles may turn off the +12V output to the 7-way connector when in park or during gear shifting, making the existing vehicle wiring incompatible with the Echo. To use Echo with these vehicles, visit a CURT authorized installer to install a power wire to the battery.

Configuring Profile Settings

To enter 'Active Profile', tap the 'Open' button shown under the image of Echo®. In your 'Active Profile' screen, you can adjust settings and use the Echo® Brake controller.

1. Manual Brake Activation

Activate manual braking, press and hold the orange button. Manual brake controller activation is used in situations where a slow reduction in speed is desirable. As the manual control is activated, the Echo® begins to apply the trailer brakes. Manual output can be activated by pressing and holding the orange button in the app.

2. Brake Output Indicator

The orange outer ring indicates current brake output level. The orange outer ring is a visual indicator of the current level of power being applied to the trailer brakes. When the vehicle's brakes are fully applied, the level of power and position of the ring is determined by your max output setting.

3. Max Output

The maximum level of the brake controller. The output control establishes the max amount of power available to the trailer brakes when braking. The output should be adjusted during initial setup, when trailer load changes, when different trailers are used or when adjustment is needed for changing road or driving conditions. To edit, tap the maximum output button and increase or decrease using the '+' or '-' buttons.

4. Sensitivity Level

The sensitivity of the braking power. The sensitivity level adjusts trailer aggressiveness when activated during braking. Sensitivity adjustment has no effect on the manual brake control. The sensitivity can be adjusted for individual driver preference, trailer load changes or changing road conditions. To edit, tap the sensitivity button and increase or decrease using the '+' or '-' buttons.

5. Vehicle Hazard Lights

Turn on any time the vehicle's hazard lights are active. When the vehicle's hazard lights are activated, the trailer brakes may pulse on and off as the lights flash. To prevent pulsing brake output, toggle the switch ON any time the vehicle's hazard lights are active.

Test Drive & Adjustment

Both the output and sensitivity can be adjusted to achieve smooth, firm stops. Output and sensitivity adjustments should only be made while stopped, with the transmission in park or neutral, parking brake applied, foot off the brake pedal, and no manual control actuation.

WARNING: Perform tests and adjustments in a safe environment (parking lot or in minimal traffic area).

Starting with the output adjustment, drive forward on a dry and level paved or concrete surface. At approximately 25 mph, apply the vehicle's brakes. If trailer braking is insufficient, increase the max output setting in the OneControl® app. If the trailer brakes lock up, decrease the max output. Repeat this process until stops are firm, just short of lock up.

Once the output is set, adjust the sensitivity by driving forward at approximately 25 mph and press the brake pedal. The vehicle and trailer should make a smooth stop. If the stop seems slow and more aggressive braking is desired, increase the sensitivity level through the OneControl® app. If the stop seems too aggressive, decrease the sensitivity level in the app.

Make several stops at various speeds and adjust the sensitivity until stops are smooth and firm. Slight adjustment to the output control may also be required to achieve desired results at all test speeds. Note: If any problems occur during setup, refer to the 'Troubleshooting Guide' on the last page of this manual.

WARNING: This process must be repeated if there are any changes to weather / road conditions or significant changes in trailer weight or towing setup.

LED Status Indicator

A single LED on top of the Echo® shows the status of the brake controller unit. Refer to the icons and descriptions below.
