Section 01 TECHNICAL MANUAL
Subsection 01 (DYNAMIC POWER STEERING (DPS))
GENERAL
During assembly/installation, use the torque val-
ues and service products as in the exploded view.
WARNING
Torque wrench tightening specifications
must be strictly adhered to.
Locking devices (e.g.: locking tabs, elastic
stop nuts, cotter pins, etc.) must be replaced.
Hoses, cables or locking ties removed during a
procedure must be reinstalled as per factory stan-
dards.
SYSTEM DESCRIPTION
(FEATURES)
The Dynamic Power Steering (DPS) provides
a computer controlled, variable power assist,
achieved by an electric motor to optimize the
amount of steering input required by the rider.

1. Dynamic power steering unit (DPS)
The DPS system uses the following parameters to
determine how much steering assist it provides:
– Engine RPM
– Battery/electrical system voltage
– Vehicle speed
– DPS shaft torque sensor input.
The amount of steering assist provided is depen-
dent on the handlebar effort (steering torque),
electrical power available, and vehicle speed.
The greater the handlebar effort (torque), the
greater the assist will be.
The slower the vehicle speed, the greater the as-
sist will be.
If the electrical system is activated but the engine
is
not running, there is no power assist provided.
When the handlebar is in the straight ahead posi-
tion, there is no steering assist.
Steering torque may also come from the wheels
due to rough terrain. Steering kickback is reduced
while providing feedback to the driver.
The greater the power steering assist, the greater
the load on the electrical system.
When the electrical system is under high load
(battery not at full charge, operating the vehicle
for prolonged periods of time at slow speed and
low RPM which, requires higher power steering
assist), the battery power reserve will gradually
decrease. This further increases the load on the
charging system and the electrical system volt-
age will drop. As system voltage drops, so does
power steering assist.
NOTE: It is important to maintain the battery at
a full state of charge to ensure proper DPS op-
eration. The magneto output is increased to 650
watts minimize battery drain and system voltage
drop.
DPS Assist Mode
The DPS system normally provides two rider se-
lectable modes of operation.
DPS MAX provides maximum steering assist for
technical low speed riding in rough or muddy ter-
rain, or for touring.
DPS MIN provides less steering assist for in-
creased feedback and aggressive trail riding.
A third mode of operation is available as an acces-
sory to adjust the steering assist level for opera-
tion with an approved BRP track kit.
How to View DPS Assist Mode Selection
1. To view the active DPS ASSIST mode, press
and release the OVERRIDE/DPS button on the
LH multifunction switch assembly.
