ELECTRONIC POWER STEERING (EPS)
EPS OPERATION
The EPS module is an intelligent electronic power
steering system that operates off of the vehicle’s 12V
electrical system. It calculates steering assist by sensing
the difference between the input torque of the steering
post and the output torque required to turn the wheels,
and then provides assist by energizing an electric motor.
The process provides a smooth, seamless assist.
The system is continuously running diagnostic checks
and monitoring factors such as battery voltage, ground
speed and engine speed. In the event an internal or
external issue that affects the EPS system is detected,
the system will illuminate a fault indicator and transition
to a normal mechanically coupled steering system. The
system is Polaris Digital Wrench® compatible for
simplified
diagnostics
and
system
troubleshooting
through the vehicle’s diagnostic port.
With the engine off and the key on, the power steering
unit will operate for up to five minutes. After the five
minutes, you will need to cycle the key switch and restart
the engine to regain power steering operation.
NOTE
To conserve battery power, the EPS unit will shut down
5 minutes after the engine has stopped if the key
remains in the ON position. At this point, the EPS
Malfunction Indicator Light will illuminate to indicate the
EPS has shut down and will set a fault code in Digital
Wrench®.
The Power Steering 30A Fuse.
• If the fuse fails, the Power Steering Malfunction
Indicator Light (MIL) on the instrument cluster will
illuminate. During this time, the vehicle will have no
power steering operation. You will be able to connect
and communicate with the vehicle’s Engine Controller,
but not the Power Steering Controller, while using
Digital Wrench®.
NOTE
DO NOT SPLICE OR CUT INTO THE CAN CIRCUITS.
WARNING
Electronic Power Steering (EPS) units are not
interchangeable between ATV and
RANGER
product
lines.
NOTE
See Chapter 5 “Body/Steering/Suspension” for power
steering unit removal and installation procedures.
