Sway Command™ Controller Operation
1.
When Sway Command™ detects excessive sway, the light pod will blink red and the tow operator will
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
activations. The Sway Command™ light pod will turn off when it powers down.
