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.
Avoid distracted driving. Only make
adjustments when the vehicle is stationary.
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.
Prior to driving, test all trailer lights
while the trailer is plugged into the Echo®.
• 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.
• Echo Smart Control IS 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.
• 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.
• 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.
• 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.

WARNING
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:
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.

CONFIGURING PROFILE SETTINGS
In your 'Active Profile' screen you can adjust settings.
1. Manual Brake Activation
2. Brake Output Indicator
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.
The blue ring indicates current brake output level.
The blue 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
4. Sensitivity Level
5. Vehicle Hazard Lights
6. Screen Theme
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.
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 controller. The sensitivity can be adjusted for individual
driver preference, trailer load changes or changing road conditions.
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 this from happening, toggle the switch on
any time the vehicle’s hazard lights are active.
Change from light to dark.
Under the 'Settings' menu, the option to change for day or night
driving situations or application preference is available.

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. Note: Perform the adjustments in a safe environment
with minimal vehicle traffic.
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 brake controller application. 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 brake controller application. If the stop seems too
aggressive, decrease the sensitivity level in the application.
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 desirable. Note: If any problems occur during setup,
refer to the 'Troubleshooting Guide' on the last page of this manual.
