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. 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.
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.
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.
• 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.
• 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.

NOTICE
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.

INSTALLATION
1. Prior to insertion you will need to install the safety strap.
The safety strap is located inside the cap of the Echo®unit.
Remove the button fastener from the strap.

result in an improper calibration and inconsistent trailer braking.
2. Slide the strap through the clasp on the Echo®.
4. Insert Echo®into the vehicle 7-way socket, using the plug's
alignment notch and slot to properly orient the plug and receptacle.
3. Insert button fastener facing outwards.

'Echo®Brake Controller' is visible, select it. Once detected, select
'Connect' to pair the device. You will then be prompted to enter
the six-digit PIN, found under the cap of the brake controller
unit or on the provided quick reference card. Once pairing is
complete, you will receive a pairing successful notification
and the LED light on the Echo®device will be solid blue.
6. Plug the trailer's 7-way connector into the Echo®brake controller
using the plug’s alignment notch and slot to properly orient the
plug and receptacle. Ensure the vehicle and trailer are parked
on a level surface. The LED light on the Echo®will flash yellow
for five to eight seconds while calibration occurs. Once
the device is calibrated, the LED will turn solid green.

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
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 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
4. Sensitivity Level
5. Vehicle Hazard Lights
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.
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.
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.
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 acheive 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.
This process must be repeated if there
are any changes to weather / road conditions or
significant changes in trailer weight or towing setup.
