(For Aftermarket Applications)
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.
