The DSC Status Light Module
The DSC performs a self-diagnostic test every time it "wakes up"
by receiving a signal from a brake controller in the tow vehicle.
The light will flash RED and GREEN approximately six times on
startup and then go to GREEN. The DSC also continually monitors
system parameters during operation. If the system is operating
properly and no faults are detected, the GREEN light will remain
ON and flicker or pulse. If a problem is detected, a RED light will
flash a specific number of times to indicate the specific problem.
The following Status Light and Troubleshooting table contains the
meaning of the different RED and GREEN light flashes along with
troubleshooting suggestions to correct the problem(s).
The DSC continues checking the fault status and keeps the RED
light flashing until the fault is corrected. Once corrected, the
GREEN light returns. Note that when the trailer is not moving,
every 60 seconds the GREEN light will turn off for three seconds
and back on. This is normal and indicates proper operation of
the DSC. If the GREEN light is not turning off and on every 60
seconds while the trailer is not moving, have the DSC checked by
your local service center.
