The use of Sway Command®is
only supported/allowed for use
on caravans meeting product
specications and caravans with
approved brake control modules
(BCMs) and integrated caravan
brake control modules (ICBCMs).
See caravan requirements and
approved BCM and ICBCM Lists
at: www.lippert.com/sway-command
• The Sway Command system installed on this caravan may be
incompatible with certain manufacturers’ brake controllers.
• Please refer to the website www.lippert.com/sway-command
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 controller. The Sway Command is not
designed to be submerged under water (Water Crossing).
Submersion will cause unwarrantable damage.

Introduction
The Sway Command®tow control 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. This
system is currently only for use on caravans.
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.

Installation
Mounting Controller
Never drill into the Sway Command controller or
compromise the pressure equalizer plug hole on the back
of the controller. Doing so voids the warranty and could
damage the controller.
NOTE: The Sway Command controller is water-resistant,
but not waterproof. Do not spray high pressure water
directly at the controller.
Standard Chassis Mounting
1. The controller must be mounted in a level condition,
centered on the crossmember, and according to the
orientation arrow on the label (Fig.2A).
NOTE: The controller MUST be mounted facing the rear
of the caravan. The controller will not operate correctly if
mounted improperly.
2. Place the controller against the mounting surface. Use
a paint marker or grease pencil to locate the four mounting
holes for the Sway Command module (Fig.2B).
3. Using a drill with the 5.5 mm drill bit, drill
pilot holes through the crossmember at the four
previously marked locations. Clear all chips from the
mounting surface.
4. After the holes have been drilled, insert M6 x 11.0 x 0.7
serrated external lock washers over each #14 - 10 x 25 mm
self-drilling hex screw.
5. Insert assembled screws into the module as follows:
A. Insert one screw into the module and tighten half way
to hold the module in place.
B. Insert a second screw into the opposite corner from
the previously installed screw and tighten half way into the
module to hold the module in place.
C. Insert a third screw into the open hole on the opposite
end from the previously installed screw and tighten half
way into the module.
D. Insert the fourth screw into the remaining open hole
and tighten half way into the module.
6. Using an impact driver, securely fasten all screws using
a crisscross pattern (Fig.2) until screw heads are nearly

Sway Command Light Pod Mounting
The light pod should be mounted in a location that can be
easily seen by the tow vehicle operator. If the light pod is
mounted to the A-frame of the caravan (Fig.5), make sure
it is mounted on the driver’s side of the caravan for clear
visibility. Optionally, the light pod can be mounted to the
outside, front wall of the caravan (Fig.6) and positioned for
visibility by the tow vehicle operator.
NOTE: The light pod can be fastened to the A-frame at any
time, but can only be connected after the A-frame loom
has been routed.

Mounting the light pod on the A-frame:
1. Determine the proper mounting location for the light pod.
2. Fasten the light pod in place next to the A-frame loom
hole with two M8 x 18 x 12 mm self-tapping screws (Fig.5A).
3. Connect the light pod to the extension harness (Fig.5B)
that was previously connected to the Sway Command
main harness.
NOTE: The light pod wiring and connection point can be
coiled into the cavity on the back side of the light pod for a
cleaner appearance, if preferred.
4. If the light pod is lit green, and no error codes are
detected, place the Sway Command warning sticker
(Fig.5C) on the outside of the caravan’s A-frame next to the
light pod.
Mounting the light pod on a caravan wall:
1. Determine the proper mounting location for the light pod.
2. Attach the light pod to the caravan wall with two M8 x 25
mm square head wood screws (Fig.6A).
3. Connect the light pod to the extension harness (Fig.6B)
that was previously connected to the Sway Command
main harness.

Tow Vehicle Brake Control
Modules
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.
NOTE: The following WARNING safety label reads and
appears as shown here and as included in the kit.
NOTE: LCI attempts to provide compatibility with
aftermarket BCMs and integrated caravan brake control
modules (ICBCMs) but is unable to anticipate design
changes by other manufacturers. LCI is continually
testing BCMs and ICBCMs and advises you to visit www.
lci1.com/sway for a complete and updated list as the
website listing is periodically revised as further testing is
completed and approved.

3. Caravan brakes must be burnished to ensure proper

pressure must be adjusted to the tyre manufacturer’s
recommended pressure.
5. 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
ensure tyres have useful tread left.
6. 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. Ensure proper hitch tongue
weights are observed for the caravan.
7. The tow operator must ensure Sway Command is
operational by observing the Sway Command light pod
status. Ensure the light pod is illuminated green. See Sway
Command Status light for status other than green.
8. The operator should operate the tow vehicle as safely
as driving and weather conditions allow. Sway Command
