Your shocks are the optional Monaco ADC RV 2-Position Adjustable Shock System.
Page 232 and 233 in your owners manual explains the system, but does not help with troubleshooting. First, I would check the fuse in the front electrical bay under the drivers feet (on the outside).
I would send a PM to IRV2 member
Hypoxia as he has this system and is very knowledgeable.

Then you can perform easy searches.
Shocks - Active Control Damping (Optional)
Electronic monitoring
of the suspension,
chassis, and motorhome
speed allows constant
adjustments to be
made to the shock
damping system. This
in turn allows for better
handling characteristics,
smoother ride and overall
improved driving control.
Operation:
Shock operating modes, Comfort or Sport,
are selected from a driver’s console switch.
The driver can select which mode to operate
according to their personal preference and/or
road conditions.
Comfort:
Shock damping is reduced to provide a
smoother ride.
Sport:
Shock damping is increased to provide
an improved level of performance to the
motorhome’s ability to handle pitch, roll and
adverse driving conditions.
Indicator Lights:
The light on the selector switch indicates
the system is active. The Red LED next to the
switch will blink once when the ignition is
turned on. Should the LED remain illuminated
there is a malfunction in the system and the
mode will default to Sport.
NOTE
The motorhome is safe to drive should
the ACD system default to the hard
mode. However, contact Monaco
Technical Support to locate the nearest
service center for diagnostic and repair
