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

Sway Command Compatible Tow Vehicle Brake Control Modules
The tow vehicle brake control module (BCM) applies brakes to the trailer 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: Lippert attempts to provide compatibility with aftermarket BCMs and integrated trailer brake control modules (ITBCMs) but is unable to anticipate design changes by other manufacturers. Lippert is continually testing BCMs and ITBCMs 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.
· The Sway Command system installed on this trailer 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.
Prior to Operation
FAILURE TO FOLLOW THE GUIDELINES BELOW MAY RESULT IN DEATH, SERIOUS PERSONAL INJURY, OR PROPERTY DAMAGE.
1. Sway Command must be installed as detailed in the Sway Command Installation section. Sway Command will not operate correctly if improperly installed.
2. Trailer brakes must be adjusted per OEM specifications to ensure proper trailer braking. The tow operator must ensure trailer brakes are properly adjusted. Sway Command may not operate properly with improperly adjusted brakes. Discuss brake adjustments with the trailer OEM.
3. Trailer brakes must be burnished to ensure proper trailer braking. New electric brakes may contain a coating to prevent rust during shipping. An unburnished brake will reduce trailer braking capacity. The tow vehicle operator must ensure trailer 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 trailer OEM.
4. Improperly adjusted tire pressure can reduce braking effectiveness and can be a source of sway. Tire pressure must be adjusted to the tire manufacturer’s recommended pressure.
5. Tires must have useful tread life left to ensure proper braking. Tire tread below useful life could cause the trailer to skid during braking. The tow operator must ensure tires have useful tread left.
6. Improperly loaded trailers can be a source of sway. At higher speeds, if the trailer naturally sways, the tongue weight and/or trailer 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 trailer.

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 relies on braking and tire grip to mitigate sway, and overall effectiveness of the system may be reduced or impaired in slippery/icy driving conditions.
Sway Command Controller Operation
1. When Sway Command detects excessive sway, the light pod will blink red and the tow operator may feel the trailer brakes activate until the sway is dampened.
2. Sway Command will “wake up” if it senses external brake activations. During wake up, Sway Command performs self-checks and alternately flashes the light pod lights green and red.
NOTE: 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 troubleshooting for a description of the various blink codes.

3. Sway Command will enter a low power mode after 10 minutes when it senses no tow vehicle brake activation or movement.
4. The Sway Command light pod will turn off when it powers down.
What Should Be Done?
Unit is in low power. Activate tow vehicle brake to wake unit.
Unit is not connected to 12V DC power supply. Verify wiring.
After a few seconds, the unit will complete self-checks, and set the lights green if unit is ready, or a flashing code if an issue is found.
Every five seconds there will be a brief time the green LED turns off for a fraction of a second. This indicates unit is functional.
After sway subsides, light will return to green.
Verify the break away switch is not activated. Verify blue brake wire not shorted to 12 volts.
Verify the blue brake wire is connected to the trailer brakes.
Verify the blue brake wire is not shorted to ground or trailer frame. Verify tow vehicle and tow battery are at 12 volts.
Disconnect harness, wait 10 seconds. Connect harness. If light comes on solid red, unplug unit and contact service department.
