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 fl ashes 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 fl ashes. 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. The Sway Command™ light pod will turn off
when it powers down.
