Introduction
The Sway Command® system is a self-contained caravan stability control module that detects undesirable
caravan movement from external sensors and mitigates it by adaptively applying a variable braking voltage
to the left and right caravan electric brakes.
Note: The Sway Command System is not a replacement for using sway control bars when towing a
caravan. Sway control bars should be used in conjunction with the Sway Command System.
The Sway Command® Tow Control system uses sensors to detect excessive caravan sway. The system
activates automatically and applies voltage proportional to the amount of sway detected to the electric
caravan brakes. This dampens the sway and slows the caravan down. When excessive sway is detected, the
light pod will blink red and the tow vehicle operator may feel the caravan brakes activate until the sway
isdampened.
Causes of Sway
• When the tongue weight is less than 10% of the caravan’s weight, it has a natural tendency to sway.
• Improper weight distribution hitch adjustments.
• Crosswinds.
• A transfer truck passing from the rear of the caravan.
• Descending inclines.
• Towing speeds.
• Tow vehicle not properly matched for the caravan.
• Improper loading, overloading and poor weight distribution on the caravan.
• Incorrect tyre inflation.

Safety
Read and understand all instructions before installing or operating this product. Adhere to all safety labels.
This manual provides general instructions. Many variables can change the circumstances of the instructions,
i.e., the degree of difficulty, operation and ability of the individual performing the instructions. This
manual cannot begin to plot out instructions for every possibility, but provides the general instructions,
as necessary, for effectively interfacing with the device, product or system. Failure to correctly follow the
provided instructions may result in death, serious personal injury, severe product and/or property damage,
including voiding of the LCI limited warranty.
The "WARNING" symbol above is a sign that a procedure has a safety risk involved and may cause
death or serious personal injury and/or severe product and property damage, including voiding
of the component warranty, if not performed safely and within the parameters set forth in
thismanual.
Failure to follow instructions provided in this manual may result in death, serious personal injury
and/or severe product and property damage, including voiding of the component warranty.
• The Sway Command system installed on this caravan may be incompatible with certain
manufacturers’ brake controllers.
• Please refer to the website www.lci1.com/sway for the most current list of brake controllers
compatible with Sway Command. Also, refer to your vehicle owner’s manual for any further
instructions on your vehicle’s brake controller function.
• Failure to determine compatibility between your brake controller, your tow vehicle and Sway
Command may result in the sudden loss of brake controller braking, which can result in a loss of
vehicle control and cause serious injury or property damage.
• Do not submerge the caravan. The Sway command is not designed to be submerged under water
(Water Crossing). Extended submersion could cause Non-Warrantable damage.
The “CAUTION” symbol above is a sign that a safety risk is involved and may cause personal injury
and/or product or property damage if not safely adhered to and within the parameters set forth
in this manual.
The Sway Command controller is water-resistant, but not waterproof. Do not spray high pressure
water directly at the controller.
Always inate tyres per manufacturer's specications. In addition to causing sway, improper tyre
ination may cause premature tyre wear, poor handling, reduced fuel economy, or blowouts. Check
tyre ination weekly when the tyre is cold before operation.

Rev: 10.15.20 Page 4 CCD-0003689
Prior to Operation
Sway Command must be installed properly or it will not operate correctly.
• Caravan brakes must be adjusted per OEM specifications to ensure proper caravan braking. The tow
operator must make sure caravan brakes are properly adjusted. Sway Command may not operate properly
with improperly adjusted brakes. Discuss brake adjustments with the caravanOEM.
• Caravan brakes must be burnished to ensure proper caravan braking. New electric brakes may contain a
coating to prevent rust during shipping. A non-burnished brake will reduce caravan braking capacity. The
tow vehicle operator must make sure caravan brakes are properly burnished to ensure brakes are effective
in slowing the tow vehicle. Sway Command may not operate properly with improperly burnished brakes.
Discuss brake burnishing with the caravanOEM.
Always inate tyres per manufacturer's specications. In addition to causing sway, improper tyre
ination may cause premature tyre wear, poor handling, reduced fuel economy, or blowouts. Check
tyre ination weekly when the tyre is cold before operation.
• Improperly adjusted tyre pressure can reduce braking effectiveness and can be a source of sway. Tyre
pressure must be adjusted to the tyre manufacturer’s recommended pressure.
• Tyres must have useful tread life left to ensure proper braking. Tyre tread below useful life could cause the
caravan to skid during braking. The tow operator must make sure tyres have useful tread left.
• Improperly loaded caravans can be a source of sway. At higher speeds, if the caravan naturally sways,
the tongue weight and/or caravan weight distribution must be adjusted. Sway Command could activate
frequently in this situation causing excessive brake wear. Make sure proper hitch tongue weights are
observed for the caravan.
• The tow operator must make sure Sway Command is operational by observing the Sway Command light
pod status. Make sure the light pod is illuminated green. See the Light Codes and Troubleshooting section
for status other than green.
• The operator should operate the tow vehicle as safely as driving and weather conditions allow. Sway
Command relies on braking and tyre grip to mitigate sway, and overall effectiveness of the system may be
reduced or impaired in slippery/icy driving conditions.
Operation
When Sway Command detects excessive sway, the light pod will blink red (Fig. 1) and the tow operator may
feel the caravan brakes activate until the sway is dampened.

Note: The tow vehicle brake control module (BCM) applies brakes to the caravan when the tow operator
presses on the tow vehicle brake pedal or activates a manual switch on the tow vehicle BCM. A tow
vehicle BCM may be OEM factory installed or an aftermarket install.
The Sway Command light pod will be green if no issues are detected. If an issue is detected, the light pod
will blink green once, followed by a number of red flashes. See the Light Codes and Troubleshooting section
for additional information on blinking light codes.
Sway Command will enter a low power mode after 10 minutes when it senses no tow vehicle brake
activation or movement. The Sway Command light pod will turn off when it powers down.
Light Codes and Troubleshooting
In the event a tow vehicle brake controller detects a fault after Sway Command detects a sway event,
manually activate the tow vehicle brake controller a few times to clear the fault.
