DYNAMIX ACTIVE SUSPENSION
DYNAMIX SHOCKS DISASSEMBLY / ASSEMBLY
While the Dynamix Shocks come apart similar to a FOX Podium Bypass shock, there are several differences. Refer to
the training on University of Polaris (https://lms.latitudelearning.com/home/main.aspx) and do a search for “Live Valve
Shock” for complete disassembly and assembly of a Dymanix shock.

DEMONSTRATION MODE
"Demo" Mode allows the operator to experience the feel
associated with each Ride Mode before actual use.
Activate "Demo" Mode by placing the vehicle in Park (P)
and turning off the engine, then turn the ignition key
switch to ON position. The operator can cycle through
the different Ride Modes using the UP or DOWN arrow
buttons, then use the throttle, brakes, and steering wheel
to assess the feel of each Ride Mode.
SUSPENSION CONTROL MODULE
(SCM)
The Suspension Control Module (SCM) contains the
logic for suspension control, including communications,
operator inputs, and shock drivers, to execute the
suspension control algorithms. The SCM also has an
internal 6-axis inertial measurement unit which is used to
monitor the performance of the vehicle by the
suspension control algorithms.
CAUTION
Moving or altering the orientation of the SCM may have
an adverse effect on vehicle handling. Never move the
SCM from it’s factory mounting location.
DYNAMIX™ DV SYSTEM FEATURES
The Pro R's DYNAMIX DV (dual valve) shock (if
equipped), features both rebound and compression
control valves located on the shock. The rebound and
compression is controlled and monitored by the inertial
measurement unit (IMU) inside the suspension control
module (SCM). The 90-pin suspension control module
(SCM) is the heart of the Dynamix Active Suspension.
The IMU monitors the vehicle's yaw, pitch, and roll
positions and rates, the SCM responds by making fine
adjustments to these valves based on the suspension
mode and vehicle speed.
Both valves are amperage controlled by the SCM.
Varying the amperage to these valves changes the size
of the orifice.
A lower amperage provides a smaller orifice (more
damping) to flow shock oil through; a greater amperage
provides a larger orifice (less damping).
If the valves become damaged, they are replaced as an
assembly. The amperages can be monitored in Digital
Wrench. The system is capable of self-diagnosing issues
and codes will appear in Digital Wrench. For disassembly
and assembly please visit the MSD Garage to watch
FOX shock videos. SCM position is critical to Dynamix
DV calibration, so it must not be relocated or reoriented.
EPS RESPONSE
When Dynamix DV Ride Modes are selected, EPS unit
response & feedback is specifically tuned for each Ride
Mode, resulting in different steering feel in each ride
mode.
