(For Aftermarket Applications)
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.
