Section 07 CHASSIS
Subsection 03 (DYNAMIC POWER STEERING (DPS))
DPS MED provides normal (medium) steering as-
sist for general all purpose riding.
DPS MIN provides less steering assist for in-
creased feedback and aggressive trail riding.
A fourth mode of operation is available as an ac-
cessory to adjust the steering assist level for op-
eration with an approved BRP track kit.
Derating Explanation
Derating is an internal protection system inte-
grated in the DPS electronic module.
This system protects the electronic components
when DPS works too hard and the internal tem-
perature reaches a critical level.
It also protects electronics when current ripples in
the system are too high. These current ripples can
be caused by:
– Loose battery connections
– Low battery voltage
– Bad grounds
– Defective stator or bad stator output wires con-
nection
– Failed regulator
– High electrical loads.
The internal protection system decreases the
assistance level available to protect its electronic
board. The normal assistance level will return
when riding conditions are back to normal and
the internal temperature decrease and/or when
the ripples in the electric circuit decreases.
NOTE: This reaction is a normal protective behav-
ior of the unit and it does not necessarily raise a
fault in the cluster.
DPS SYSTEM DESCRIPTION
(COMPONENTS)
DPS Unit
The DPS unit is a self contained unit that includes
the steering gear, the DPS module, the DPS mo-
tor, and the torque sensor.

TYPICAL - DPS UNIT
The DPS module provides DC power to the mo-
tor. The amount and duration of that DC power is
determined by the inputs to the DPS module. The
direction in which the motor turns is changed by
reversing the polarity of the circuit current.
The DPS motor does not "spin", but rather turns in
very small increments based on the amount, du-
ration, and direction of DC power delivered by the
DPS module.
DPS Unit Protection
To protect the DPS electronic components, the
steering assist behavior will change as follows.
CONDITION
When motor internal
temperature reaches a certain
temperature (DPS continuously
estimates it)
DPS internal board
temperature is above
85°C (185°F)
DPS internal board
temperature is above
100°C (212°F)
When the DPS unit temperature is back within
normal operating range, normal steering assist
will resume.
DPS BEHAVIOR
Steering assist
will gradually
decrease
Steering assist
is stopped
