MAINTENANCE
PERIODIC MAINTENANCE CHART
Periodic Maintenance Overview
Inspection, adjustment and lubrication of important components are explained in the periodic maintenance chart.
Inspect, clean, lubricate, adjust and replace parts as necessary. When inspection reveals the need for replacement parts, use
genuine Pure Polaris parts available from your Polaris dealer.
NOTE: Service and adjustments are critical. If you’re not familiar with safe service and adjustment
procedures, have a qualified dealer perform these operations.
Maintenance intervals in the following chart are based upon average riding conditions and an average vehicle speed of approximately
10 miles per hour. Vehicles subjected to severe use must be inspected and serviced more frequently.
Severe Use Definition
• Frequent immersion in mud, water or sand
• Racing or race-style high RPM use
• Prolonged low speed, heavy load operation
• Extended idle
• Short trip cold weather operation
Pay special attention to the oil level. A rise in oil level during cold weather can indicate contaminants collecting in the oil sump or
crankcase. Change oil immediately if the oil level begins to rise. Monitor the oil level, and if it continues to rise, discontinue use
and determine the cause or see your dealer.
Break-In Period
The break-in period consists of the first 25 hours of operation, or the time it takes to use 14 gallons (53 liters) of fuel. Careful treatment
of a new engine and drive components will result in more efficient performance and longer life for these components.
• Drive vehicle slowly at first while varying the throttle position. Do not operate at sustained idle.
• Pull only light loads.
• Perform regular checks on fluid levels and other areas outlined on the daily pre-ride inspection checklist.
• Change both the engine oil and filter after 25 hours or one month.
• See “Owner’s Manual” for additional break-in information.
Maintenance Chart Key
The following symbols denote potential items to be aware of during maintenance:
 = CAUTION: Due to the nature of these adjustments, it is recommended this service be performed by an
authorized Polaris dealer.
= SEVERE USE ITEM: See information provided above.
E = Emission Control System Service (California).
NOTE: Inspection may reveal the need for replacement parts. Always use genuine Polaris parts.
WARNING
Improperly performing the procedures marked could result in component failure and lead to serious injury or death.
Have an authorized Polaris dealer perform these services.

Engine Oil Level
NOTE: Make certain the dipstick is inserted all the
way into the filler tube to keep the angle and depth of
dipstick consistent.
The twin cylinder engine is a wet-sump engine, meaning the oil
is contained in the bottom of the crankcase. To check the oil
level follow the procedure listed below:
1.
Position vehicle on a level surface.
2.
Place the transmission in Park (P).
3.
Be sure the machine has sat for awhile before removing the
dipstick.
7.
Remove dipstick and check to see that the oil level is in the
SAFE range. Add oil as indicated by the level on the
dipstick. Do not overfill (see NOTE below!).

Reinstall the dipstick completely, but do not lock it.
DO NOT Overfill the Engine
Locate the engine oil dipstick:
• RZR / RZR S: Remove both seats and the rear service
panel to access the dipstick.
NOTE: Due to the dipstick entry angle into the
crankcase, the oil level will read higher on the
bottom side of the dipstick. Proper level indication is
determined on the upper surface of the dipstick as it
is being removed, regardless of the level marks
being on top or on bottom (see the next illustration).

COOLING SYSTEM
4.
Cooling System Overview
The engine coolant level is controlled, or maintained, by the
recovery system. The recovery system components are the
recovery bottle, radiator filler neck, radiator pressure cap and
connecting hose.
NOTE: If overheating is evident, allow system to
cool completely and check coolant level in the
radiator and inspect for signs of trapped air in
system.
WARNING
As coolant operating temperature increases, the expanding
(heated) excess coolant is forced out of the radiator past the
pressure cap and into the recovery bottle. As engine coolant
temperature decreases the contracting (cooled) coolant is drawn
back up from the tank past the pressure cap and into the radiator.
NOTE: Some coolant level drop on new machines is
normal as the system is purging itself of trapped air.
Observe coolant levels often during the break-in
period.
NOTE: Overheating of engine could occur if air is
not fully purged from system.
Polaris Premium 60/40 is already premixed and ready to use. Do
not dilute with water.
Never remove the pressure cap when the
engine is warm or hot. Escaping steam can
cause severe burns. The engine must be cool
before removing the pressure cap.
5.
Remove the pressure cap. Using a funnel, add coolant to the
top of the filler neck.
6.
Reinstall the pressure cap.
NOTE: Use of a non-standard pressure cap will not
allow the recovery system to function properly.
7.
Remove recovery bottle cap and add coolant using a funnel.
8.
Fill recovery bottle to MAX level with Polaris 60/40
premix Anti Freeze/Coolant or 50/50 or 60/40 mixture of
antifreeze and distilled water as required for freeze
protection in your area.
9.
Reinstall the recovery bottle cap.
Coolant Level Inspection
The pressure cap and recovery bottle are located under the front
hood of the vehicle. The coolant level must be maintained
between the minimum and maximum levels indicated on the
recovery bottle.
If the coolant level is below the MIN line, inspect the
coolant level in the radiator.
10. If coolant was required, start engine and check for leaks.
Make sure radiator fins are clean to prevent overheating.
Coolant Strength / Type
Recovery Bottle
Test the strength of the coolant using an antifreeze hydrometer.
Pressure Cap
Antifreeze Hydrometer
• A 50/50 or 60/40 mixture of antifreeze and distilled
water will provide the optimum cooling, corrosion
protection, and antifreeze protection.
With the engine at operating temperature, the coolant level
should be between the upper and lower marks on the coolant
recovery bottle. If not, perform the following procedure:
1.
Position the vehicle on a level surface.
2.
Remove the hood from the front cab.
3.
View the coolant level in the recovery bottle.
• Do not use tap water, straight antifreeze, or straight
water in the system. Tap water contains minerals and
impurities which build up in the system.
• Straight water or antifreeze may cause the system to
freeze, corrode, or overheat.

first, and then at front and rear. Try to move the wheel
and hub by pushing inward and pulling outward.
Wheel Toe Alignment Inspection
1.
Place machine on a smooth level surface and set steering
wheel in a straight ahead position. Secure the steering
wheel in this position.
2.
Place a chalk mark on the center line of the front tires
approximately 10” (25.4 cm) from the floor or as close to
the hub/axle center line as possible.
NOTE: It is important the height of both marks be
equally positioned to get an accurate measurement.
3.
4.
Check for Loose Wheel or Hub
5.
Measure the distance between the marks and record the
measurement. Call this measurement “A”.
Rotate the tires 180 by moving the vehicle forward.
Position chalk marks facing rearward, even with the hub/
axle center line.
Again measure the distance between the marks and record.
Call this measurement “B”. Subtract measurement “B”
from measurement “A”. The difference between
measurements “A” and “B” is the vehicle toe alignment.
The recommended vehicle toe tolerance is 1/8”, to 1/4”, (.3
to .6 cm) toe out. This means the measurement at the front
of the tire (A) is 1/8”, to 1/4”, (.3 to .6 cm) wider than the
measurement at the rear (B).

CAUTION
During tie rod adjustment, it is very important that
the following precautions be taken when
tightening tie rod end jam nuts.
If the rod end is positioned incorrectly it will not
pivot, and may break.
To adjust toe alignment:
• Hold tie rod end to keep it from rotating.
• Loosen jam nuts at both end of the tie rod.
• Shorten or lengthen the tie rod until alignment is as
required to achieve the proper toe setting as specified in

add DOT 4 brake fluid only.
2.
Inspect the brake pad wear surface for excessive wear.
3.
Pads should be changed when the friction material is worn
to .040” (1 mm).
Brake fluid should be changed every two years. The fluid should
also be changed anytime the fluid becomes contaminated, the
fluid level is below the minimum level, or if the type and brand
of the fluid in the reservoir is unknown.
The brake fluid master cylinder reservoir can be accessed
through the left front wheel well.
1.
Position the vehicle on a level surface.
2.
Place the transmission in PARK (P).
3.
View the brake fluid level in the reservoir. The level should
be between the MAX and MIN level lines.
4.
If the fluid level is lower than the MIN level line, add brake
fluid until it reaches the MAX level line.
5.
Install the reservoir cap and apply the brake pedal
forcefully for a few seconds and check for fluid leakage
around the master cylinder fittings and the brake caliper
fittings.

1.
Remove the front hood (see Warning under “Cooling
System Pressure Test”).
2.
Remove pressure cap and test using a pressure cap tester
(commercially available).
3.
The pressure cap relief pressure is 13 psi. Replace cap if it
does not meet this specification.
Recommended Coolant
Use only high quality antifreeze/coolant mixed with distilled
water in a 50/50 or 60/40 ratio, depending on freeze protection
required in your area.
CAUTION: Using tap water in the cooling system will lead to
a buildup of deposits which may restrict coolant flow and reduce
heat dissipation, resulting in possible engine damage. Polaris
Premium 60/40 Antifreeze/Coolant is recommended for use in
all cooling systems and comes pre-mixed, ready to use.
The system must maintain 10 psi for five minutes or longer.
If pressure loss is evident within five minutes, check the
radiator, hoses, clamps and water pump seals for leakage.

CAUTION
Use caution when performing these procedures.
Coolant may be hot and may cause
severe injury or burns.
NOTE: If the coolant level is LOW in the radiator, or
if there are leaks in the system, the coolant system
will not draw coolant from the reservoir tank.
5.
Leave the cap off of the radiator to allow any possible air
to escape.
6.
Start the engine and let it idle for 5-10 minutes or until the
thermostat opens and allows coolant to flow through the
system.
Drive the vehicle onto a slight incline and use properly
weight rated ramps. If an incline is not available, slightly
elevate the front of the vehicle.
7.
Squeeze the coolant lines by hand to help purge the system
of air.
Place the vehicle in Park and block the rear wheels.
8.
Slightly loosen the bleed screw (C) on the cylinder head to
let air escape. If no air is present, a steady stream of coolant
will stream out. If air is present, the screw will bubble and
sputter as the air escapes.
NOTE: Use this procedure when a unit overheats
and no apparent leaks in the cooling system are
found.

Oil Flow Chart
This chart describes the flow of oil through the 800 EFI engine. Beginning in the crankcase sump, the oil is drawn through an oil
galley to the feed side of the oil pump. The oil is then pumped through the oil filter. If the oil filter is obstructed, a bypass valve
contained in the filter allows oil to bypass the filter element. At this point, the oil is supplied to the main oil galley through a crankcase
passage. Oil is then diverted three ways from the main oil galley, with the first path entering the camshaft bores, onto the rear balance
shaft journal and then draining back into the crankcase sump. The second oil path from the main oil galley feeds the lifter bores and
then drains back to the crankcase sump. The third oil path flows through a crankcase galley to the MAG side crankshaft journal and
also to the front balance shaft journal and onto the crankcase sump.

Combustion Chamber
1.
Clean all accumulated carbon deposits from combustion
chamber and valve seat area with carbon cleaner and a soft
plastic scraper.
IMPORTANT: Do not use a wire brush, metal scraper,
or abrasive cleaners to clean the bottom of the
cylinder head. Extensive damage to the cylinder head
may result. Wear safety glasses during cleaning.
Combustion Area
NOTE: Valve seat width and point of contact on the
valve face is very important for proper sealing. The
valve must contact the valve seat over the entire
circumference of the seat, and the seat must be the
proper width all the way around. If the seat is
uneven, compression leakage will result. If the seat
is too wide, seat pressure is reduced, causing
carbon accumulation and possible compression
loss. If the seat is too narrow, heat transfer from
valve to seat is reduced. The valve may overheat and
warp, resulting in burnt valves.
1.
Install pilot into valve guide.
2.
Apply cutting oil to valve seat and cutter.
3.
Place 46 cutter on the pilot and make a light cut.
Valve Seat Reconditioning
NOTE: Polaris recommends that the work be done
by a local machine shop that specializes in this area.
NOTE: The cylinder head valve guides cannot be
replaced.
WARNING
Wear eye protection or a face shield during
cylinder head disassembly and reassembly.
Valve Seat Inspection
Inspect valve seat in cylinder head for pitting, burnt spots,
roughness, and uneven surface. If any of the above conditions
exist, the valve seat must be reconditioned. If the valve seat is
cracked the cylinder head must be replaced.
Follow the manufacturers instructions provided with the valve
seat cutters in the commercially available cylinder head
reconditioning kit. Abrasive stone seat reconditioning
equipment can also be used. Keep all valves in order with their
respective seat.

4.
Inspect the cut area of the seat:
* If the contact area is less than 75% of the circumference of the
seat, rotate the pilot 180 and make another light cut.
NOTE: When using an interference angle, the seat
contact point on the valve will be very narrow, and is
a normal condition. Look for an even and continuous
contact point all the way around the valve face (A).
B
* If the cutter now contacts the uncut portion of the seat, check
the pilot. Look for burrs, nicks, or runout. If the pilot is bent it
must be replaced.
* If the contact area of the cutter is in the same place, the valve
guide is distorted from improper installation.
A
* If the contact area of the initial cut is greater than 75%,
continue to cut the seat until all pits are removed and a new seat
surface is evident. NOTE: Remove only the amount of material
necessary to repair the seat surface.
5.
Proper Seat Contact
on Valve Face
To check the contact area of the seat on the valve face, apply
a thin coating of Prussian Blue paste to the valve seat. If
using an interference angle (46) apply black permanent
marker to the entire valve face (A).

* If the seat is too wide or uneven, use both top and bottom
cutters to narrow the seat.
* If the seat is too narrow, widen using the 45 cutter and recheck contact point on the valve face and seat width after each
cut.

Cylinder Hone Selection and Honing
Procedure
Cylinders may be wet or dry honed depending upon the hone
manufacturer’s recommendations. Wet honing removes more
material faster and leaves a more distinct pattern in the bore.
If cylinder wear or damage is excessive, it will be necessary to
replace the cylinder. The cylinders are lined with a nicasil
coating and are not repairable. Hone only enough to de-glaze the
outer layer of the cylinder bore.
CAUTION
A hone which will straighten as well as remove
material from the cylinder is very important.
Using a common spring loaded glaze breaker
for honing is not advised for nicasil cylinders.
Polaris recommends using a rigid hone or arbor
honing machine. Cylinders may be wet or dry
honed depending upon the hone manufacturer's
recommendations.
Wet honing removes more material faster and
leaves a more distinct pattern in the bore.
3
Example of Cross Hatch Pattern
IMPORTANT: Clean the cylinder after honing
If cylinder wear or damage is excessive, it will be necessary to
replace the cylinder. The cylinders are lined with a nicasil
coating and are not repairable. Hone only enough to de-glaze the
outer layer of the cylinder bore.
Honing To Deglaze
A finished cylinder should have a cross-hatch pattern to ensure
piston ring seating and to aid in the retention of the fuel/oil
mixture during initial break in. Hone cylinder according to hone
manufacturer's instructions, or these guidelines:
• Honing should be done with a diamond hone. Cylinder
could be damaged if the hone is not hard enough to
scratch the nicasil lining.
• Use a motor speed of approximately 300-500 RPM, run
the hone in and out of the cylinder rapidly until cutting
tension decreases. Remember to keep the hone drive
shaft centered (or cylinder centered on arbor) and to
bring the stones approximately 1/2” (1.3 cm) above and
below the bore at the end of each stroke.
Cleaning the Cylinder After Honing
It is very important that the cylinder be thoroughly cleaned after
honing to remove all grit material. Wash the cylinder in a
solvent, then in hot, soapy water. Pay close attention to areas
where the cylinder sleeve meets the aluminum casting (transfer
port area). Use electrical contact cleaner if necessary to clean
these areas. Rinse thoroughly, dry with compressed air, and oil
the bore immediately with Polaris Lubricant.
• Release the hone at regular intervals and inspect the
bore to determine if it has been sufficiently de-glazed,
and to check for correct cross-hatch.
NOTE: Do not allow cylinder to heat up during honing.
• After honing has been completed, inspect cylinder for
thinning or peeling.

The EFI system is designed to provide peak engine performance
with optimum fuel efficiency and lowest possible emissions.
The ignition and injection functions are electronically
controlled, monitored and continually corrected during
operation to maintain peak performance.
Squeeze Connector Tabs
The central component of the system is the Bosch Electronic
Control Unit (ECU) which manages system operation,
determining the best combination of fuel mixture and ignition
timing for the current operating conditions.

2.
Pull on the fuel line for removal.
3.
To install the line(s), verify the connections are clean and

4.
Snap the fuel line back over the nipple and slide the locking
mechanism back into place. Verify the connector tabs snap
back into place.
An in-tank electric fuel pump is used to move fuel from the tank
through the fuel line, to the fuel rail. The in-tank fuel pressure
regulator maintains a system operating pressure and returns any
excess fuel back into the tank. At the engine, fuel is fed through
the fuel rail and into the injectors, which inject into the intake
ports. The ECU controls the amount of fuel by varying the
length of time that the injectors are "on." This range can vary
depending on fuel requirements. The controlled injection of the
fuel occurs every other crankshaft revolution, or once for each
4-stroke cycle. The total amount of fuel needed for one firing of
a cylinder is injected during each cycle. When the intake valve
opens, the fuel/air mixture is drawn into the combustion
chamber, ignited and burned.

ELECTRONIC FUEL INJECTION
The ECU controls the amount of fuel being injected and the
ignition timing by monitoring the primary sensor signals for
intake air temperature, manifold absolute pressure (load),
engine temperature, speed (RPM), camshaft position and
throttle position. These primary signals are compared to the
programming in the ECU computer chip, and the ECU adjusts
the fuel delivery and ignition timing to match the values.
During operation, the ECU has the ability to re-adjust
temporarily; providing compensation for changes in overall
engine condition and operating environment, so it will be able
to maintain the ideal air/fuel ratio.
During certain operating periods such as cold starts, warm up,
acceleration, etc., a richer air / fuel ratio is automatically
calculated by the ECU.
ELECTRONIC CONTROL UNIT (ECU)
Operation Overview
The ECU is the brain or central processing computer of the
entire EFI fuel/ignition management system. During operation,
sensors continuously gather data which is relayed through the
wiring harness to input circuits within the ECU. Signals to the
ECU include: ignition (on/off), crankshaft position and speed
(RPM), camshaft position (MAG/PTO), throttle position,
engine coolant temperature, intake air temperature, intake
manifold absolute pressure and battery voltage. The ECU
compares the input signals to the programmed maps in its
memory and determines the appropriate fuel and spark
requirements for the immediate operating conditions. The ECU
then sends output signals to set the injector duration and ignition
timing.
Initial Priming / Starting Procedure
NOTE: The injection system must be purged of all
air prior to the initial start up, and / or any time the
system has been disassembled.
If the EFI system is completely empty of fuel or has been
disassembled and repaired:
1.
Cycle the key switch from “OFF” to “ON” 6 times, waiting
for approximately 3 seconds at each “ON” cycle to allow
the fuel pump to cycle and shut down.
2.
Once step 1 is completed, turn the key switch to “START”
until the engine starts or 5 seconds has passed.
3.
If the engine failed to start, repeat step 1 for 2 more cycles
and attempt to start the engine.
If the engine fails to start, a problem may still exist, and should
be diagnosed.
NOTE: Accurate testing of EFI components is
recommended utilizing the Digital Wrench™
Diagnostic Software (dealer only).
RZR / RZR S

driver’s seat
ECU

- Located under left

ECU
During operation, the ECU continually performs a diagnostic
check of itself, each of the sensors, and system performance. If
a fault is detected, the ECU turns on the “Check Engine” light
in the speedometer and stores the fault code in its fault memory.
Depending on the significance or severity of the fault, normal
operation may continue, or "Fail-Safe" operation (slowed speed,
richer running) may be initiated. A technician can determine the
cause of the “Check Engine” light by referencing the
“Instrument Cluster Trouble Code Display” and “Diagnostic
Trouble Code Table” or by using Digital Wrench™. The ECU
requires a minimum of 7.0 volts to operate. The memory in the
ECU is operational the moment the battery cables are
connected.
To prevent engine over-speed and possible failure, an RPM
limiting feature is programmed into the ECU. If the maximum
RPM limit is exceeded, the ECU suppresses the injection
signals, cutting off the fuel flow and retards the ignition timing.
This process repeats it self in rapid succession, limiting
operation to the preset maximum.

All operating and control functions within the ECU are pre-set.
No internal servicing or readjustment may be performed. If a
problem is encountered, and you determine the ECU to be
faulty, contact the Polaris Service Department for specific
handling instructions. Do not replace the ECU without factory
authorization.
The relationship between the ECU and the throttle position
sensor (TPS) is very critical to proper system operation. If the
TPS is faulty, or the mounting position of the TPS to the throttle
body is altered, the TPS must be adjusted.
For the purpose of troubleshooting, a known-good ECU from
another Polaris RANGER RZR EFI of the same model may be
used without system or engine component damage.

FUEL INJECTORS
Upper Rear Gearcase Bolt
Operation Overview
NOTE: All EFI units utilize quick connect fuel lines.
The fuel injectors mount into the cylinder head, and the fuel rail
attaches to them at the top end. O-rings on both ends of the
injector prevent external fuel leaks and also insulate it from heat
and vibration.
Fuel
Injectors
7.
Torque the remaining bolt that attaches the bracket to the
front side of the rear gearcase.
Fuel Rail
Front Rear Gearcase Bolt
When the key switch is on, the fuel rail is pressurized, and the
EFI relay provides voltage to the injectors. During engine
operation, the ECU completes the ground circuit, energizing the
injectors. The valve needle in the injector is opened
electromagnetically, and the pressure in the fuel rail forces fuel
down through the inside. The “director plate” at the tip of the
injector contains a series of calibrated openings which directs
the fuel into the intake port in a cone-shaped spray pattern.
NOTE: A multi-directional torque wrench is required
in this application because of the limited access to
this bolt. Check with the manufacturer of your torque
wrench to see if it can be used to tighten left-hand
threaded bolts.
The amount of fuel injected is controlled by the ECU and
determined by the length of time the valve needle is held open,
also referred to as the “injection duration” or “pulse width”. It
may vary in length depending on the speed and load
requirements of the engine.
The ECU gathers fuel injection timing information from the
Crankshaft Position Sensor and Camshaft Phase Sensor to allow
for sequential fuel injection.

Fuel Injector Service
Fuel Injector Test
Injector problems typically fall into three general categorieselectrical, dirty / clogged, or leakage. An electrical problem
usually causes one or both of the injectors to stop functioning.
Several methods may be used to check if the injectors are
operating.
NOTE: The harness connector and locking spring is
bonded to the fuel injectors with an epoxy. DO NOT
attempt to disconnect the connector from the fuel
injectors. Damage will occur to the injector and/or
harness if attempting to separate at that location.
Separate the fuel injector from the vehicle harness
as shown in the illustration below.
• With the engine running at idle, feel for operational
vibration, indicating that they are opening and closing.
• When temperatures prohibit touching, listen for a
buzzing or clicking sound with a screwdriver or
mechanic's stethoscope.
Fuel
Injector
Disconnect Here
Harness
• Disconnect the electrical connector from an injector and
listen for a change in idle performance (only running on
one cylinder) or a change in injector noise or vibration.
NOTE: Do not apply voltage directly to the fuel
injector(s). Excessive voltage will burn out the
injector(s). Do not ground the injector(s) with the
ignition on. lnjector(s) will open/turn on if relay is
energized.
If an injector is not operating, it can indicate either a bad injector,
or a wiring/electrical connection problem. Check as follows:
Injector leakage is very unlikely, but in rare instances it can be
internal (past the tip of the valve needle), or external (weeping
around the injector body). The loss of system pressure from the
leakage can cause hot restart problems and longer cranking
times.
Injector problems due to dirt or clogging are unlikely due to the
design of the injectors, the high fuel pressure, the use of filters
and the detergent additives in the gasoline. Symptoms that could
be caused by dirty/clogged injectors include rough idle,
hesitation/stumble during acceleration, or triggering of fault
codes related to fuel delivery. Injector clogging is usually caused
by a buildup of deposits on the director plate, restricting the flow
of fuel, resulting in a poor spray pattern. Some contributing
factors to injector clogging include; dirty air filters, higher than
normal operating temperatures, short operating intervals and
dirty, incorrect, or poor quality fuel. Cleaning of clogged
injectors is not recommended; they should be replaced.
Additives and higher grades of fuel can be used as a preventative
measure if clogging has been a problem.

FUEL PUMP
The ECU switches off the pump preventing the continued
delivery of fuel in these instances:
Operation Overview
An electric fuel pump assembly is used to transfer fuel to the EFI
system from inside the fuel tank. This assembly includes the fuel
pump, fuel filters, regulator and fuel gauge sender. The pump is
rated for a minimum output of 25 liters per hour at 45 +/- 2 psi
and has two non-serviceable fuel filters.
Fuel Pump Assembly
• If the key switch is not promptly turned to the "start"
position.
• If the engine fails to start.
• If the engine is stopped with the key switch "on" (as in
the case of an accident).
In these situations, the “check engine” light will go on, but will
turn off after 4 cranking revolutions if system function is OK.
Once the engine is running, the fuel pump remains on.
Fuel Sender Test
If the fuel gauge reading on the instrument cluster is not
working, or if the display reading differs in large comparison to
the fuel in the tank, perform a resistance test on the fuel sender.
Disconnect the fuel pump / sending unit connection and measure
the resistance. If out of specification, replace the fuel pump
assembly.

Fuel Pump Test
If a fuel delivery problem is suspected, make certain the fuel
pump filters are not plugged, that the pump is being activated
through the ECU, all electrical connections are properly
secured, the fuses are good, and a minimum of 7.0 volts is being
supplied. If during starting the battery voltage drops below 7.0
volts, the ECU will fail to operate the system.
Normal Fuel Pressure: 45 +/- 2 psi.
NOTE: If the fuel pressure is out of specification,
replace the fuel pump assembly.

WARNING
If the pump did not activate (Step 5), disconnect the harness
connector from the fuel pump. Connect a DC voltmeter
across terminals “3” and “4” in the plug on the vehicle fuel
pump harness. Turn on the key switch and observe voltage
to ensure a minimum of 7 volts is present.
Fuel is extremely flammable and may cause
severe burns, injury, or death.
Do not use any device that produces a flame or
electrical devices that may spark around
fuel or fuel vapors.
1.
Remove the passenger seat from the vehicle.
2.
Cover the fuel line connection at the fuel tank with a shop
towel and disconnect the line from the fuel pump outlet.
3.

Adaptor (PV-48656). Route the clear hose into a portable
gasoline container or the vehicle’s fuel tank.
NOTE: If the voltage was below 7 VDC, test the
battery, ignition switch, relay(s), wiring harness and
ECU.
7.
If the reading is between 7 and 14 volts, turn key switch off
and connect an ohmmeter between terminals “3” and “4”'
at the white fuel pump connector to check for continuity
within the fuel pump.
NOTE: If there was no continuity between the pump
terminals, replace the fuel pump assembly.
PU-43506-A
8.
PV-48656
If voltage at the plug was within the specified range, and
there was continuity across the pump terminals, reconnect
the plug to the fuel pump, making sure you have a clean
connection. Turn on the key switch and listen for the pump
to activate.
NOTE: If the pump starts, repeat steps 3, 4 and 5 to
verify correct pressure.
5.
Turn on the key switch to activate the pump and check the
system pressure on the gauge. If system pressure of 45 psi
 2 is observed, the ignition switch, ECU, fuel pump, and
pressure regulator are working properly. Turn the key
switch off and depress the valve button on the tester to
relieve the system pressure.
9.
If the pump still does not operate, check for correct ECU
operation by plugging in a known-good ECU of the same
model.
NOTE: If the pump still does not operate, replace the
fuel pump assembly.

THROTTLE POSITION SENSOR (TPS)
TPS Resistance Tests
Operation Overview
The TPS is a non-serviceable item. If it is faulty, it must be
replaced. It can be tested using the following method:
The throttle position sensor (TPS) is used to indicate throttle
plate angle to the ECU. Mounted on the throttle body and
operated directly off the end of the throttle shaft, the TPS works
like a rheostat, varying the voltage signal to the ECU in direct
correlation to the angle of the throttle plate. This signal is
processed by the ECU and compared to the internal preprogrammed “maps” to determine the required fuel and ignition
settings for the amount of engine load.
With the test leads connected and the meter set to the ohms scale,
observe the reading at the following pin locations of the TPS:

Operation Overview
ECT Sensor Resistance Readings
Mounted on the cylinder head, the engine temperature sensor
measures coolant temperature. The engine temperature sensor is
a Negative Temperature Coefficient (NTC) type sensor, as the
temperature increases the resistance decreases.

ECT Sensor Replacement
Coolant passes through the cylinder and by the sensor probe,
varying a resistance reading which is relayed to the ECU. This
signal is processed by the ECU and compared to its
programming for determining the fuel and ignition
requirements during operation. The ECU also uses this signal to
determine when to activate the fan during operation.
ECT Sensor Test
To quickly rule out other components and wiring related to the
ECT, disconnect the harness from the ECT sensor and start the
engine. After a few seconds, the fan should turn on and the
“Check Engine” indicator should display on the instrument
cluster. This indicates all other components are working
properly.

IGNITION COIL
Ignition Coil Tests
Operation Overview
The ignition coil can be tested by using an ohm meter. Use the
following illustration and specification table to test the ignition
coil resistance.
The ignition coil is used to provide high voltage to fire the spark
plugs. When the ignition key is on, DC voltage is present in
primary side of the ignition coil windings. During engine
rotation, an AC pulse is created within the crankshaft position
sensor for each passing tooth on the flywheel. The two-tooth gap
creates an “interrupt” input signal, corresponding to specific
crankshaft position. This signal serves as a reference for the
control of ignition timing. The ECU then calculates the time
interval between the consecutive pulses, and determines when
to trigger the voltage spike that induces the voltage from the
primary to the secondary coil windings to fire the spark plugs.

Engine Controller Reprogramming (Reflash)
• KNOW THE PROCESS: If you are not familiar with
the entire reprogramming process, review the HELP
section of the diagnostic software before you attempt
reprogramming. Click on the ? on the tool bar or press
F11. The information in the on-line help is the most
current and complete information available. This
should be your first step until you are familiar with the
process.
Process Overview
The reprogramming feature is in the Special Tests menu on the
Digital Wrench™ screen. Start Digital Wrench™ and click on
the Special Tests menu icon (red tool box). A technician should
be familiar with the process and with computer operation in
general before attempting to reprogram an ECU.
• COMMUNICATION PROBLEMS: If you have had
problems communicating with a vehicle while
performing diagnostic functions, do not attempt
reprogramming until the cause has been identified and
fixed. Check all connections, and be sure battery
voltage is as specified.
The Digital Wrench™ Engine Controller Reprogramming (or
“Reflash”) feature allows reprogramming of the ECU fuel and
ignition map. To successfully reprogram the ECU, an
Authorization Key must be obtained by entering a Request Code
in the box provided on the Reflash Authorization site. The
Request Code is automatically generated by Digital Wrench™
during the reprogramming process. The Reflash Authorization
site is located under the “Service and Warranty” drop down
menu on the dealer website at: www.polarisdealers.com.
Proceed to http://polaris.diagsys.com for specific
information and FAQs on how to troubleshoot
communication problems.
IMPORTANT: Failure to follow the reprogramming
instructions completely and correctly can result in an
engine that does not run! Replacement ECUs are
programmed as “no-start” and require a reflash for
them to work.
Reprogramming (Reflash) Tips:
• BATTERY VOLTAGE: The majority of problems with
reprogramming can be attributed to a low battery. Be
sure the battery voltage (no load) is at least 13 volts and
at least 12.5 volts with the key ‘ON’. Connect a battery
charger if necessary to bring voltage level above
minimum. Fully charge the battery before you attempt
to reprogram.
• DEDICATED LAPTOP: Best results are obtained using
a laptop computer that is “dedicated to Digital
Wrench™”. A laptop that is used by a variety of people
and in several applications around the dealership is
more likely to cause a reprogramming problem than one
dedicated to Digital Wrench™ diagnostics only.
• OBTAINING
THE
LATEST
UPDATE:
Reprogramming updates are provided periodically and
contain the most recent calibrations (see “Digital
Wrench™ Updates”).
• CLOSE NON-ESSENTIAL PROGRAMS: Polaris
recommends that you DO NOT install non-essential
programs on a Service Department laptop. Camera
detection software, Virus Scanners, Tool Bars, etc. may
clog up memory if running in the background and make
it harder for the diagnostic software to operate.
• DON’T DISTURB THE PC: While reprogramming is
in progress, don’t move the mouse and don’t touch the
keyboard. The process only takes a few minutes, and is
best left alone until complete.
Reprogramming (Reflash) Procedure:
If you are not familiar with the reprogramming process, review
the “Reprogramming (Reflash) Tips” before you begin. Follow
the on-screen instructions as you progress through the steps. If
you encounter a problem, always check the On-Line help for
current tips and information.

DECAL REPLACEMENT
SHOCKS / SPRINGS / FASTENERS
Exploded View (RZR / RZR S)
WARNING
Retainer gap
should be 180°
from spring end
The following procedure involves the use of an
open flame. Perform this procedure in a well
ventilated area, away from gasoline or other
flammable materials. Be sure the area to be
flame treated is clean and free of gasoline
or flammable residue.
WARNING
Do not flame treat components that are installed
on the vehicle. Remove the component from the
vehicle before flame treating.
5
The side panels, front and rear fender cabs are plastic
polyethylene material. Therefore, they must be “flame treated”
prior to installing a decal to ensure good adhesion. A bonus of
the flame treating procedure is it can be used to reduce or
eliminate the whitish stress marks that are sometimes left after
a fender or cab is bent, flexed, or damaged.
CAUTION
Exploded View (RZR S / RZR S INT’L)
Do not flame treat painted plastic components.
Painted plastic surfaces should only be wiped
clean prior to decal adhesion.
To flame treat the decal area:
1.
Pass the flame of a propane torch back and forth quickly
over the area where the decal is to be applied until the
surface appears slightly glossy. This should occur after just
a few seconds of flame treating. Do not hold the torch too
close to the surface (2-3 inches from the flame tip is
recommended). Keep the torch moving to prevent damage.
2.
Apply the decal on one edge first. Slowly lay down
remainder of the decal while rubbing lightly over the decal
surface to eliminate any air bubbles during the application.
Retainer gap
should be 180°

FOX™ Shock Rebuild Information
When performing maintenance on FOX™ shocks, use the Gas
Shock Recharging Kit (PN 2200421), as it contains the
necessary valves, pressure gauge, and fittings to deflate and
pressurize shocks.
Special Tools Required:
Body Holding Tool (PN 2871071)
Charging Needle (PN 7052069-A)
Gas Shock Recharging Kit (PN 2200421)
FOX™ Shock IFP Tool (PN 2871351)

NOTE: Read through all of these instructions first to
familiarize yourself with the rebuild procedure. Make
sure you have a clean work area, and all of the
necessary tools are available. Always use proper
safety equipment when working on shock
absorbers.
NOTE: Clean the entire shock assembly with soapy
water. Try to remove as much dirt and grime as
possible by scrubbing with a soft bristle brush.
Never pressure wash your shock, as this can force
water and debris inside which will damage the seals.
Dry the shock assembly with compressed air, if
available, or use clean towels.
1.
If your shock DOES NOT have a spring installed, skip to
Step #4.
Measure the spring set length (Fig. 1). Record this number.
2.
Back the preload adjustment ring off until spring is loose
on the body. Remove the lower spring retaining clip.
3.
Remove the spring.
4.
If the shock has spherical bearings in the body cap or shaft
eyelet, remove the reducer bushings and O-rings from both
ends of the shock. If your shock has polyurethane bushings
and sleeves, remove them from both ends of the shock
(Fig. 1).
6.
Clean the entire shock assembly with soapy water. Try to
remove as much dirt and grime as possible by scrubbing
with a soft bristle brush. Never pressure wash your shock,
as this can force water and debris inside which will damage
the seals. Dry the shock assembly with compressed air, if
available, or use clean towels.
7.
Use a 3/32” Hex Key to remove the button head screw from
the FOX™ air valve in the reservoir end cap.
8.
Securely clamp FOX™ Nitrogen Safety Needle in vise.
CAUTION
Figure 1

12. Clamp the body cap of the shock securely in vise with shaft
side up.
13. Gently tap the reservoir end cap with a rubber mallet to
expose the wire retaining ring. Locate the end of the ring
and push inward with fingertip. Remove the retaining ring.
A scribe or dental pick can also be used for this step, but
use extreme caution not to scratch the bore of the reservoir
tube (Fig. 4).
17. Align the slot of the IFP Depth Setting Tool with the end
of the IFP (Internal Floating Piston). Engage the IFP by
rotating the tool 90 degrees (Fig. 6). Gently pull the IFP out
of the reservoir tube using the IFP Depth Setting Tool, and
place it on a clean, lint free towel. Remove the shock from
the vise and pour shock oil from body and reservoir tubes
into a proper disposal container. DO NOT RE-USE OLD
SHOCK OIL.

14. Use pliers to grab flats of the gas valve of reservoir cap.
Extract cap from reservoir tube using a rocking or twisting
motion. Set reservoir cap aside on a clean, lint free paper
towel.
15. Use the appropriate size wrench to loosen the bearing
assembly (Fig. 5).
Unscrew the bearing assembly completely from the body
tube. Remove the shaft assembly from the body tube, and
place on a clean, lint free paper towel. Remove the shock
from the vise and pour shock oil from body tube into a
proper disposal container.
NOTE: DO NOT RE-USE OLD SHOCK OIL.
Figure 5
18. Using the 1/8” Hex Tool, remove the IFP bleed screw from
the IFP.
19. Clean the body tube, reservoir tube, and the IFP using
solvent. Dry with compressed air in a well ventilated area.
If compressed air is not available, dry parts using clean, lint
free paper towels and let sit in a well ventilated area to allow
the solvents to evaporate.
20. Set body assembly aside on a clean, lint free paper towel.
21. Clamp the shaft eyelet securely in vise with the piston end
up.
22. Using a 9/16” wrench, remove the piston lock nut from the
end of the shaft.
23. Hold the tip of a phillips head screwdriver against the end
of shaft. Hold the piston assembly under the top-out plate
and lift upwards (Fig. 7). Slide the piston assembly onto the
shaft of the Screwdriver. Pull the Screwdriver away from
shock shaft while supporting the piston assembly. Slide a
12” tie wrap through the entire piston assembly. Secure the
two ends of the zip tie together and remove the screwdriver.
There are many pieces to the piston assembly, and the
assembly order of these pieces is critical to the proper
performance of your shock. This step ensures that the
proper order is kept. Place piston assembly on a clean, lint
free paper towel.

3.
Use a scribe or dental pick to remove the O-ring seal from
the IFP.
4.
Use a scribe or dental pick to remove the O-ring seals from
the reservoir end cap.
5.
Install the new, well lubricated, O-rings into the bearing
housing. Correct placement of the shaft seal O-ring is in the
groove next to the DU bushing. Check to make sure the
seals are properly seated, and are not twisted. If a tool is
required to aid in proper seating of O-ring, use the nonwriting end of a pen, or a similar soft, blunt object, to push
it in.
6.
Install the new U-cup seal into bearing. U-cup should be
installed so the cupped end is facing the DU bushing inside
of bearing. Check to make sure seal is properly seated. If a
tool is required to aid in proper seating of U-cup seal, use
the non-writing end of a pen, or a similar soft, blunt object,
to push it in (Fig. 10).
1.
Use a scribe or dental pick to remove the U-cup wiper
(Fig. 8) and O-ring seals (Fig. 9) from the bearing housing.
Be careful not to scratch the seal grooves or the DU
bushing that is pressed into the bearing.
Figure 8
IMPORTANT: Use extreme caution when using a
scribe to remove seals. Always ”spear” the seal with
the point of the scribe. Do not wedge the point of the
scribe in behind the seal. This can scratch the surface
of the seal groove which will compromise the
performance and reliability of the shock absorber.

10. Install the new, well greased O-rings into the reservoir end
cap.
Fill the reservoir to the retaining ring groove with the
recommended oil. You should see bubbles rising to oil
surface. Wait until bubbling slows or stops completely. If
oil level has fallen, add more oil until level is at retaining
ring groove. Insert IFP into reservoir. Use a smooth motion
and push straight in until O-ring seats into the retaining ring
groove. Use your free hand to wrap new piston band around
IFP with the rounded edge out, and push the IFP into the
reservoir. Shock oil will come up through the IFP bleed
hole.

3.
Insert the shaft of a Phillips head screwdriver through the
center of the piston assembly. The pointed end of the
screwdriver should be on the same side as the top-out plate.
Cut and remove the tie wrap that was holding the piston
assembly together.
4.
Hold the piston assembly from underneath the top-out plate
and place the end of the screwdriver onto the end of the
shock shaft. Slide the piston assembly onto the shaft end.
Check to make sure the piston assembly is properly seated,
then install the piston lock nut. Torque the nut to 18 ft. lbs.
(24 Nm) using a torque wrench and 9/16” socket. Remove
shaft assembly from vise and set it aside on a clean, lint free
paper towel.
5.
Clamp the body cap of the shock securely in the vise, with
the open end of the body facing up.
6.
Using the flat blade screwdriver, turn the compression
adjuster screw counter clockwise until it stops turning.
7.
Lubricate the new IFP O-ring with an ample amount of
assembly lube.
10. Quickly install the IFP Bleed Screw before the oil level
drops and tighten it with the 1/8” Hex Tool (Fig. 13).
NOTE: The IFP will spin in the reservoir when the
screw bottoms. This is OK.

12. Fill shock body to the bottom of bearing threads with oil.
13. Using the IFP Depth Setting Tool, slowly pull the IFP up
to the mid point of the reservoir. Then push it down to the
bottom again (Fig. 14). Be careful not to pull the IFP out
completely. Also, be careful that the oil level in the shock
body does not disappear below the bottom of the body and
into the reservoir. If the oil does recede completely from the
body, you must remove the IFP and go back to step 7 of
reassembly.
20. Add oil to the body tube until the surface of the oil is to the
top of the threads inside the body tube.
21. Pull the damping piston up until it is just below the surface
of the oil. Add more oil if necessary.
22. Hold the shaft eyelet with one hand. With other hand, slide
the bearing assembly down the shaft until contact with the
body is made. Oil will overflow from around the bearing
(Figure 16).
Figure 16
Figure 14
14. As you push the IFP down, you should see bubbles rising
to the surface inside the body tube. Repeat this process
several times until you don’t see any new bubbles inside the
body tube.
15. Pull the IFP up until it’s top is approximately 1” from the
end of the reservoir and remove the IFP depth setting tool.
Again, be sure the oil level in the shock body does not drop
below the bottom of the body. If the oil does recede
completely from the body, you must remove the IFP and go
back to step 7 of reassembly. Add oil if necessary while
pulling up on the IFP.
16. Using the flat blade screwdriver, turn the Compression
Adjuster Screw clockwise until it stops turning.
17. Fill the body tube with oil approximately 1/4” below the
threads. Wrap the new piston band around the piston,
making sure the rounded edges face out. Insert the shaft
assembly into the body tube. Slowly push shaft into body
until piston assembly is approximately 1” below oil surface.
18. Stroke the shaft up and down slowly over about a 1” range
until no air bubble rise from the damping piston. Be careful
to keep the damping piston at least 1/4” below the surface
of the oil during this process.
19. Bring the damping piston up until it is approximately 1/4”
below the surface of the oil. Using the mallet, give 2 - 3
sharp blows to the eyelet, driving the damping piston down
into the shock body. This opens the valves on the damping
piston. You will see the released air bubbles come to the
surface of the oil.
23. Screw the bearing assembly into the body tube by hand,
holding the shaft up so that the bearing is in contact with
the bottom of the damping piston assembly. Be careful not
to cross-thread the bearing assembly. When the bearing will
no longer thread in by hand, turn the Compression Adjuster
Screw all the way counter clockwise using the flat blade
screwdriver.
24. Tighten the bearing assembly using the appropriate size
open end wrench.
25. Set IFP depth tool to specified length for the correct IFP
depth.
Shock IFP Depth:
Front: 2.40” (6.10 cm)
Rear: 3.40” (8.64 cm)
26. Insert IFP depth setting tool into reservoir and engage IFP.
Using a long 1/8” hex tool, remove the bleed screw from
the center of the IFP. TIP: Apply grease to the end of the
hex tool so that the bleed screw sticks to it. This will make
it easier to remove it from the IFP.
27. Push the IFP down to the correct depth setting. As you do
this, keep the open end of the IFP depth setting tool covered
with your hand. Oil will stream through the bleed hole in
the IFP as you push it further into the reservoir (Fig. 17).

34. Continue charging with gas as you pull the reservoir away
from the FOX™ Nitrogen Safety Needle using a smooth,
straight motion. Keep the reservoir as straight as possible
to prevent the safety needle from bending. As the safety
needle is pulled free from the FOX™ air valve, a popping
sound should be heard.
Figure 17
Figure 19
28. Install IFP bleed screw and tighten using the 1/8” hex tool.
Remove the IFP depth setting tool. Pour the residual oil out
of the reservoir tube into a proper disposal container.
29. Install the reservoir end cap with the FOX™ air valve
facing the outside of the reservoir tube. Push down on the
reservoir end cap using even pressure, until the retaining
ring groove is exposed. Install the wire retaining ring, and
check to make sure retaining ring is seated properly.
30. Push the shaft assembly completely into the body tube
(Fig. 18). It should go all the way down smoothly and
without interference. If it does not, disassemble and
reassemble per this procedure. Do not attempt to pull the
shaft assembly back out by hand.

WARNING
CHARGE THE SHOCK USING NITROGEN GAS
ONLY. DO NOT FILL WITH ANY OTHER GASES.
Doing so compromises the performance of the shock
and may be EXTREMELY DANGEROUS!
35. Install the button-head screw into the FOX™ air valve,
using a 3/32” hex key.
Figure 18
36. Remove the shock from the vise.
37. Clean all oil residue from the shock and reservoir with
solvent, and dry with compressed air in a well ventilated
area. If compressed air is not available, dry the shock and
reservoir using clean, lint free paper towels and let sit in a
well ventilated area to allow the solvents to evaporate.
38. Reinstall the spring and the spring retainer.
39. Thread the spring preload ring down against the spring, and
set the preload to the measurement you took when you
removed the spring.
31. If reservoir cap is not properly seated against the retaining
clip, tap it gently with a rubber mallet until it snaps into
place. Remove shock assembly from vise.
32. Securely clamp FOX™ Nitrogen Safety Needle in the vise.
Be sure to point the air valve away from your face and body.
33. Insert the safety needle squarely into center of FOX™ air
valve, and pressurize the reservoir. Continue filling until
the shaft has fully extended and the reservoir pressure is at
200 psi (Fig. 19).
40. Using the flat blade screwdriver, turn the Compression
Adjuster Screw all the way clockwise until it stops. Now
turn it counter clockwise while counting the clicks until it
matches the original setting which you wrote down during
disassembly.
41. Remove the shock from the vise.
42. Reinstall spherical bearing O-rings and reducers or
polyurethane bushings and sleeves.
NOTE: After installation, be sure to RIDE SLOWLY
initially to ensure the shock and the vehicle’s
suspension is performing correctly.

PVT SYSTEM OVERVIEW
General Operation
WARNING
All PVT maintenance or repairs should be performed by
a certified Polaris Master Service Dealer (MSD)
technician who has received the proper training and
understands the procedures outlined in this manual.
Because of the critical nature and precision balance
incorporated into the PVT components, it is
absolutely essential that no disassembly or repair
be made without factory authorized special tools
and service procedures.
The Polaris Variable Transmission (PVT) consists of three
major assemblies:
1) The Drive Clutch

2) The Driven Clutch
3) The Drive Belt
The internal components of the drive clutch and driven clutch
control engagement (initial vehicle movement), clutch upshift
and backshift. During the development of the Polaris vehicle,
the PVT system is matched first to the engine power curve; then
to average riding conditions and the vehicle’s intended usage.
Therefore, modifications or variations of components at random
are never recommended. Proper clutch setup and careful
inspection of existing components must be the primary
objective when troubleshooting and tuning.
Drive Clutch Operation
Drive clutches primarily sense engine RPM. The two major
components which control its shifting function are the shift
weights and the coil spring. Whenever engine RPM is
increased, centrifugal force is created, causing the shift
weights to push against rollers on the moveable sheave, which
is held open by coil spring preload. When this force becomes
higher than the preload in the spring, the outer sheave moves
inward and contacts the drive belt. This motion pinches the
drive belt between the spinning sheaves and causes it to rotate,
which in turn rotates the driven clutch.
At lower RPM, the drive belt rotates low in the drive clutch
sheaves. As engine RPM increases, centrifugal force causes the
drive belt to be forced upward on drive clutch sheaves.

CLUTCHING
Driven Clutch Operation
Maintenance / Inspection
Driven clutches primarily sense torque, opening and closing
according to the forces applied to it from the drive belt and the
transmission input shaft. If the torque resistance at the transmission input shaft is greater than the load from the drive belt,
the drive belt is kept at the outer diameter of the driven clutch
sheaves.
Under normal use the PVT system will provide years of trouble
free operation. Periodic inspection and maintenance is required
to keep the system operating at peak performance. The
following list of items should be inspected and maintained to
ensure maximum performance and service life of PVT
components. Refer to the troubleshooting checklist at the end of
this chapter for more information.
As engine RPM and horsepower increase, the load from the
drive belt increases, resulting in the belt rotating up toward the
outer diameter of the drive clutch sheaves and downward into
the sheaves of the driven clutch. This action, which increases the
driven clutch speed, is called upshifting.
Should the throttle setting remain the same and the vehicle is
subjected to a heavier load, the drive belt rotates back up toward
the outer diameter of the driven clutch and downward into the
sheaves of the drive clutch. This action, which decreases the
driven clutch speed, is called backshifting.
In situations where loads vary (such as uphill and downhill) and
throttle settings are constant, the drive and driven clutches are
continually shifting to maintain optimum engine RPM. At full
throttle a perfectly matched PVT system should hold engine
RPM at the peak of the power curve. This RPM should be
maintained during clutch upshift and backshift. In this respect,
the PVT system is similar to a power governor. Rather than vary
throttle position, as a conventional governor does, the PVT
system changes engine load requirements by either upshifting or
backshifting.

4.
PVT System Sealing. Refer to the appropriate
illustration(s) on the following pages. The PVT system is
air cooled by fins on the drive clutch stationary sheave. The
fins create a low pressure area in the crankcase casting,
drawing air into the system through an intake duct. The
opening for this intake duct is located at a high point on the
vehicle (location varies by model). The intake duct draws
fresh air through a vented cover. All connecting air ducts
(as well as the inner and outer covers) must be properly
sealed to ensure clean air is being used for cooling the PVT
system and also to prevent water and other contaminants
from entering the PVT area. This is especially critical on
units subjected to frequent water forging.
A proper break-in of the clutches and drive belt will ensure a
longer life and better performance. Break in the clutches and
drive belt by operating at slower speeds during the 10 hours as
recommended (see Chapter 3 “Engine Break-In Period” for
break-in example). Pull only light loads. Avoid aggressive
acceleration and high speed operation during the break-in
period.

Overheating / Diagnosis
During routine maintenance, or whenever PVT system overheating is evident, it’s important to check the inlet and outlet ducting
for obstructions. Obstructions to air flow through the ducts will significantly increase PVT system operating temperatures. The
vehicle should be operated in Low when plowing or pulling heavy loads, or if extended low speed operation is anticipated.

Belt Removal
1.
Remove outer clutch cover as described in the “PVT
Disassembly” section.
2.
Mark the drive belt direction of rotation so that it can be
installed in the same direction.
NOTE: Belt is normally positioned so that the part
number can be easily read.
3.
4.
Belts with thin spots, burn marks, etc., should be replaced
to eliminate noise, vibration, or erratic PVT operation. See
the Troubleshooting Chart at the end of this chapter for
possible causes.
Belt Installation
NOTE: Be sure to position belt in the same position
as when removed or so part number is easily read.
1.
Loop belt over the drive clutch and over top of the driven
sheave.
2.
While pushing down on top of belt, turn the back, or
moveable driven sheave, clockwise.
3.
The belt then should be able to be pushed down into and
between the sheaves.
4.
Continue rotating the driven clutch and belt clockwise until
the belt is fully installed.
To remove drive belt, place the transmission in “Park” and
push down on the belt firmly to open the clutch sheaves.
Then lift upward on the belt while pulling it out and down
over the driven clutch outer sheave.
PVT Break-In (Drive Belt / Clutches)
A proper break-in of the clutches and drive belt will ensure a
longer life and better performance. Break in the clutches and
drive belt by operating at slower speeds during the 10 hour
break-in period as recommended (see Chapter 3 “Engine
Break-In Period” for break-in example). Pull only light loads.
Avoid aggressive acceleration and high speed operation during
the break-in period.
Belt Inspection
1.
Inspect belt for hour glassing (extreme circular wear in at
least one spot and on both sides of the belt). Hour glassing
occurs when the drive train does not move and the drive
clutch engages the belt.
2.
Inspect belt for loose cords, missing cogs, cracks,
abrasions, thin spots, or excessive wear. Compare belt
measurements with a new drive belt. Replace if necessary.

DRIVE CLUTCH SERVICE
Spring Specifications
The drive clutch spring has two primary functions:
1.
To control clutch engagement RPM. The springs,
which have a higher rate when the clutch is in
neutral, will increase clutch engagement RPM.
2.
To control the rate at which the drive belt moves
upward in the drive clutch sheaves. This is referred
to as drive clutch upshift.
Red/White
7043349
Red/Blue
7043372
There are other components which control upshift, but the
spring is one of the primary components in insuring
optimum performance. It is very important that the spring
is of the correct design and is in good condition.
Red/Green
7043382
CAUTION
Never shim a drive clutch spring to increase its
compression rate. This may result in complete
stacking of the coils and subsequent clutch
cover failure.

The drive clutch spring is one of the most critical components of the PVT
system. It is also one of the easiest to service. Due to the severe relaxation the
spring is subject to during operation, it should always be inspected for
tolerance limits during any clutch operation diagnosis or repair.
With the spring resting on a flat surface, measure its free length from the outer
coil surfaces as shown. Refer to the spring specification chart for specific free
length measurements and tolerances. Also check to see that spring coils are
parallel to one another. Distortion of the spring indicates stress fatigue,
requiring replacement.

Shown below are the shift weights which have been designed for the PVT system. These shift weights have many factors designed
into them for controlling engagement RPM and shifting patterns. Shift weights should not be changed or altered without first having
a thorough understanding of their positioning and the effects they may have on belt to sheave clearance, clutch balance and shifting
pattern.

Drive Shaft / CV Joint Handling Tips
4.
Care should be exercised during drive shaft removal or when
servicing CV joints. Drive shaft components are precision parts.
Make sure the circlip remains on the shaft and not left in
the joint. Discard the circlip as it will be replaced.
Circlip
Cleanliness and following these instructions is very important to
ensure proper shaft function and a normal service life.
• The complete drive shaft and joint should be handled by
getting hold of the interconnecting shaft to avoid
disassembly or potential damage to the drive shaft
joints.
• Over-angling of joints beyond their capacity could
result in boot or joint damage.
• Make sure surface-ground areas and splines of shaft are
protected during handling to avoid damage.
• Do not allow boots to come into contact with sharp
edges or hot engine and exhaust components.
• The drive shaft is not to be used as a lever arm to
position other suspension components.
Pull shaft to remove
from CV joint
5.
IMPORTANT: If the grease in the joint is obviously
contaminated with water and/or dirt, the joint should
be replaced.
6.
Thoroughly clean the joint with an appropriate solvent and
dry the joint to prevent any residual solvent from being left
in the joint upon reassembly.
7.
Visually inspect the joint by tilting the inner race to one side
to expose each ball. Severe pitting, galling, play between
the ball and its cage window, any cracking or damage to the
cage, pitting or galling or chips in raceways call for joint
replacement.
• Never use a hammer or sharp tools to remove or to
install boot clamps.
• Be sure joints are thoroughly clean and that the proper
amount and type of grease is used to refill when joint
boots are replaced and when joints are cleaned. Refer to
text for grease capacity of CV joints and CV joint
boots.
8.
Apply a light coat of grease to the end of the drive shaft and
slide the new clamp and boot (small end first) over the shaft
and position the boot in its groove machined in the shaft.
9.
Install a NEW circlip on the end of the shaft.
Outer CV Joint / Boot Replacement
NOTE: Refer the “Electronic Parts Catalog” for the
required parts to service the drive shaft. Some drive
shafts have “Boot Replacement Kits” that include a
new boot, clamps, and the required amount of
grease.
1.
Remove clamps from rubber boot using the proper boot
clamp pliers.
CV Boot Clamp Pliers:
Earless Type - 8700226
Remove the small clamp and boot from the drive shaft.
10. Grease the joint with the special CV joint grease provided
in the boot replacement kit. Fill the cavity behind the balls
and the splined hole in the joint’s inner race. Pack the ball
tracks and outer face flush with grease. Place any remaining
grease into the boot. Install small boot clamp.
NOTE: It is very important to use the correct type
and quantity of grease by using the grease
contained in the boot kit. DO NOT use a substitute
grease and DO NOT overfill or under fill the CV joint.

the joint. Discard the circlip.
6.
Remove the boot from the drive shaft.
CAUTION
Complete disassembly of the plunging joint is
NOT recommended. The internal components
are a precision fit and develop their own
characteristic wear patterns. Intermixing the
internal components could result in looseness,
binding, and/or premature failure of the joint.
IMPORTANT: If the grease in the joint is obviously
contaminated with water and/or dirt, the joint should
be replaced.
7.
Thoroughly clean the joint with an appropriate solvent and
dry the joint to prevent any residual solvent from being left
in the joint upon reassembly.
8.
Visually inspect the joint by tilting the inner race to one side
to expose each ball. Severe pitting, galling, play between
the ball and its cage window, any cracking or damage to the
cage, pitting or galling or chips in raceways call for joint
replacement.

All Wheel Drive Operation
The AWD switch may be turned on or off while the vehicle is
moving, however, AWD will not enable until the engine RPM
drops below 3100. Once the AWD is enabled, it remains enabled
until the switch is turned off.
Engage the AWD switch before getting into conditions where
the front wheel drive may be needed. If the rear wheels are
spinning, release the throttle before switching to AWD.
CAUTION
AWD Engagement: When the AWD switch is activated, the
AWD coil is powered by a 12 Vdc input which creates a
magnetic field. This magnetic field attracts an armature plate
that is keyed to the roll cage. When the ring gear and roll cage
are spinning (vehicle is moving), the energized coil and
armature plate will apply drag to the roll cage that indexes the
rollers inside the ring gear to an engagement position. While in
the engagement position, the front drive will be in an “overrunning” condition (not engaged), until the rear wheels lose
traction. Once the rear wheels begin to lose traction, the front
drive will engage by coupling the output hubs to the ring gear via
the rollers. The front drive will remain engaged until the torque
requirement goes away (i.e. rear wheels regain traction).
Switching to AWD while the rear wheels are
spinning may cause severe drive shaft and
gearcase damage. Always switch to AWD while
the rear wheels have traction or are at rest.
With the AWD switch off, the vehicle drives through the rear
wheels only (2 wheel drive). When the AWD is enabled, the
front drive acts as an on-demand AWD system. This means, the
front drive will engage once the rear wheels have lost traction,
and will remain engaged until the torque requirement goes away
(i.e. rear wheels regain traction).

CAUTION
If the rear wheels are spinning, release the

If AWD is engaged while the wheels are
spinning, severe drive shaft and front
gearcase damage could result.

AWD Disengagement: Once the rear wheels regain traction,
the front wheels will return to the “over-running” condition. The
vehicle is now back to rear wheel drive until the next loss of rear
wheel traction occurs.
Torsion Spring Operation: The torsion spring acts as a return
mechanism to help disengage the coupling of the output hubs
and ring gear by creating an “over-running” condition for the
rollers upon disengagement.

AWD Diagnosis
5.
Symptom: AWD Will Not Engage
1.
Check the gearcase coil resistance. To test the coil
resistance, measure between the Grey and Brown/White
wires. The measurement should be within specification.
Check to make sure the coil is seated in the U-shaped insert
that is pressed into the gearcase cover. The top of the coil
should be seated below the U-shaped insert. The U-shaped
insert controls the pole gap. If the top of the coil is above
the surface of the U-shaped insert it raises the armature
plate, thereby increasing pole gap. If the pole gap increases
the coil will not be strong enough to engage the AWD
system. If this is found, replace the cover plate assembly.

6.
Inspect the rollers for nicks and scratches. The rollers must
slide up, down, in and out freely within the roll cage sliding
surfaces and H-springs.
7.
Inspect the roll cage assembly for cracks or excessive wear.
If damaged, replace the roll cage assembly.
21.6 - 26.4 Ohms
2.
Turn the ignition and AWD switches on and place gear
selector in High or Low gear. Check for minimum battery
voltage at the Gray and Brown/White chassis wires that
power the coil. A minimum of 11 Vdc should be present.
3.
If electrical tests are within specification, remove gearcase
(see “Gearcase Removal”) and inspect components.
4.
Inspect the armature plate for a consistent wear pattern.
There should be two distinct wear bands (one band inside
the other). If only one band of wear is present (or if there
is wear between the two bands), inspect the coil area as
indicated in Step 5. A wear band with an interrupted wear
mark may indicate a warped plate, which may cause
intermittent operation. See the following illustrations:

REAR GEARCASE (RZR S INT’L)
Shift Yoke
General Operation
Clutch Gear
The RZR S INT’L rear gearcase has three traction operational
modes: AWD, Differential Lock, and Differential Unlock.
Locking the rear differential is beneficial in low traction and
rough terrain conditions. Unlocking the rear differential makes
maneuvering easier and minimizes damage to turf and sensitive
terrains.
Differential - Unlock
AWD
When “Differential-Lock” is selected on the switch, power is
removed from the electrical solenoid allowing the solenoid
plunger to retract. Spring tension moves the shift yoke back into
place and engages the clutch gear into the engagement dogs that
are attached to the differential gear assembly, locking the rear
differential as a solid rear axle.
Differential - Lock
Differential - Unlock
When “Differential-Unlock” is selected on the switch, the rear
differential becomes unlocked for tighter turns. An electrical
solenoid mounted in the rear gearcase housing actuates the shift
yoke. The solenoid plunger extends out to move the shift yoke
and slides the clutch gear away from the engagement dogs that
are attached to the differential gear assembly. This unlocks the
rear differential.
When switch position is set
to “Lock”, power is removed
from the solenoid and spring
tension retracts the
plunger to engage
the clutch gear
and lock the
differential.
When switch position is set
to “Unlock”, the solenoid is
powered and the
plunger extends
to disengage the
clutch gear and
unlock the
differential.

When the clutch gear is unlocked the rear drive shafts are
dependent on the differential allowing tighter turns. When it’s
locked it becomes a solid rear axle increasing traction.

TROUBLESHOOTING
Troubleshooting Checklist
Check the following items when shifting difficulty is
encountered:
• Idle speed adjustment
• PVT alignment
• Transmission oil type/quality
• Transmission torque stop adjustment (where applicable)
• Engine torque stop adjustment (where applicable)
• Drive belt deflection
• Loose fasteners on rod ends
• Loose fasteners on selector box
• Worn rod ends, clevis pins, or pivot arm bushings
• Linkage rod adjustment and rod end positioning
• Shift selector rail travel
• Worn, broken or damaged internal transmission
components
NOTE: To determine if shifting difficulty is caused
by an internal transmission problem, isolate the
transmission by disconnecting the shifter from
transmission bellcrank. Verify the engine RPM is set
to specification. Manually select each gear range at
the transmission bellcrank, and test ride vehicle. If it
functions properly, the problem is outside the
transmission.
If transmission problem remains, disassemble
transmission and inspect all gear dogs for wear
(rounding), damage. Inspect all bearings, circlips,
thrust washers and shafts for wear.

BRAKE SYSTEM SERVICE NOTES
Disc brake systems are light weight, low maintenance, and perform well in the conditions this vehicle will routinely encounter. There
are a few things to remember when replacing disc brake pads or performing brake system service to ensure proper system function
and maximum pad service life.
• Optional pads are available to suit conditions in your area. Select a pad to fit riding style and environment.
• DO NOT over-fill the master cylinder fluid reservoir.
• Make sure the brake pedal returns freely and completely.
• Adjust stop pin on front caliper after pad service.
• Check and adjust master cylinder reservoir fluid level after pad service.
• Make sure atmospheric vent on reservoir is unobstructed.
• Test for brake drag after any brake system service and investigate cause if brake drag is evident.
• Make sure caliper moves freely on guide pins (where applicable).
• Inspect caliper piston seals for foreign material that could prevent caliper pistons from returning freely.
• Perform a brake burnishing procedure after installing new pads to maximize service life.
• DO NOT lubricate or clean the brake components with aerosol or petroleum products. Use only approved brake cleaning
products.
BRAKE NOISE TROUBLESHOOTING
Dirt or dust buildup on the brake pads and disc is the most common cause of brake noise (squeal caused by vibration). If cleaning
does not reduce the occurrence of brake noise, Permatex™ Disc Brake Quiet can be applied to the back of the pads. Follow directions
on the package. This will keep pads in contact with caliper piston(s) to reduce the chance of squeaks caused by dirt or dust.
Brake Noise Troubleshooting
Possible Cause
Dirt, dust, or imbedded material on pads or disc
Remedy
Spray disc and pads with CRC Brakeleen™ or an equivalent
non-flammable aerosol brake cleaner. Remove pads and/or disc
hub to clean imbedded material from disc or pads.
Pad(s) dragging on disc (noise or premature pad wear) because
of improper adjustment
Master cylinder reservoir overfilled
Master cylinder compensating port restricted
Master cylinder piston not returning completely
Caliper piston(s) not returning
Operator error (riding the brake)
Adjust pad stop (front calipers)
Loose wheel hub or bearings
Check wheel and hub for abnormal movement.
Brake disc warped or excessively worn
Replace disc
Brake disc misaligned or loose
Inspect and repair as necessary
Noise is from other source (axle, hub, disc or wheel)
If noise does not change when brake is applied check other
sources. Inspect and repair as necessary
Wrong pad for conditions
Change to a softer or harder pad
9
Set to proper level
Clean compensating port
Inspect. Repair as necessary
Clean piston(s) seal

BRAKES
HYDRAULIC BRAKE SYSTEM OPERATION
The Polaris brake system consists of the following components or assemblies: brake pedal, master cylinder, hydraulic brake lines,
brake calipers, brake pads, and brake discs, which are secured to the drive line.
When the foot activated brake lever is applied it applies pressure on the piston within the master cylinder. As the master cylinder
piston moves inward it closes a small opening (compensating port) within the cylinder and starts to build pressure within the brake
system. As the pressure within the system is increased, the pistons located in the brake calipers move outward and apply pressure
to the moveable brake pads. These pads contact the brake discs and move the calipers in their floating bracket, pulling the stationary
side pads into the brake discs. The resulting friction reduces brake disc and vehicle speed.
The friction applied to the brake pads will cause the pads to wear. As these pads wear, the piston within the caliper moves further
outward and becomes self adjusting. Fluid from the reservoir fills the additional area created when the caliper piston moves outward.
Brake fluid level is critical to proper system operation. Too little fluid will allow air to enter the system and cause the brakes to feel
spongy. Too much fluid could cause brakes to drag due to fluid expansion.
Located within the master cylinder is the compensating port which is opened and closed by the master cylinder piston assembly. As
the temperature within the hydraulic system changes, this port compensates for fluid expansion or contraction. Due to the high
temperatures created within the system during heavy braking, it is very important that the master cylinder reservoir have adequate
space to allow for fluid expansion. Never overfill the reservoir! Do not fill the reservoir beyond the MAX LEVEL line!
When servicing Polaris brake systems use only Polaris DOT 4 Brake Fluid (PN 2872189). WARNING: Once a bottle is opened,
use what is necessary and discard the rest in accordance with local laws. Do not store or use a partial bottle of brake fluid. Brake
fluid is hygroscopic, meaning it rapidly absorbs moisture. This causes the boiling temperature of the brake fluid to drop, which can
lead to early brake fade and the possibility of serious injury.

Electrical Service Notes
Brake Light Switch
Keep the following notes in mind when diagnosing an electrical
problem:
1.
• Refer to wiring diagram for stator and electrical
component resistance specifications.
• When measuring resistance of a component that has a
resistance value under 10 Ohms, remember to subtract
meter lead resistance from the reading. Connect the
leads together and record the resistance. The resistance
of the component is equal to tested value minus the lead
resistance.
The brake switch can be accessed by removing the driver’s
seat (RZR / RZR S) or the left rear passenger seat (RZR 4).
The switch is located under the outer PVT cover along the
lower frame. The brake pressure switch is installed into the
cross fitting block.
PVT Cover
• Become familiar with the operation of your meter. Be
sure leads are in the proper jack for the test being
performed (i.e. 10A jack for current readings). Refer to
the Owner’s Manual included with your meter for more
information.
Brake Switch
• Voltage, amperage, and resistance values included in
this manual are obtained with a Fluke™ 77 Digital
Multimeter (PV-43568). This meter is used when
diagnosing electrical problems. Readings obtained with
other meters may differ.
• Pay attention to the prefix on the multimeter reading (K,
M, etc.) and the position of the decimal point.
• For resistance readings, isolate the component to be
tested. Disconnect it from the wiring harness or power
supply.
2.
Disconnect wire harness from switch and connect an
ohmmeter across switch contacts. The reading should be
infinite (OL).
3.
Apply the brake and check for continuity. If there is no
continuity or if resistance is greater than 0.5 ohms, clean the
switch terminals. Re-test and replace switch if necessary.

REAR DIFF SOLENOID (INT’L)
Differential Solenoid Overview
The differential solenoid is located on the rear gear case. The
solenoid actuates an engagement dog, which locks and unlocks
the rear differential. Refer to Chapter 7 for more information on
the rear differential mechanical operation.
Differential Solenoid Circuit Operation
The Rear Diff Solenoid Relay is attached to the rear plastic LH
panel divider behind the driver’s seat.
When the switch is pushed to activate “TURF”, a ground signal
is provided to the ECU from the AWD / 2WD / TURF Switch.
Depending on engine speed and gear position criteria, the ECU
energizes the Rear Diff Solenoid Relay allowing it to enable the
differential solenoid.
If the rear differential fails to switch from operational modes:
• Check the solenoid and relay connectors. Look for
loose wires or bad connections.
• Check for power from the relay connector, to ensure the
solenoid has power to be activated.
• Check the AWD / 2WD / TURF Switch wires for loose
connections.
• Remove solenoid from rear differential and ensure the
solenoid plunger is actuating.
CAUTION
Do not power the solenoid with 12 Volts for more
than 1 second, or damage may occur to solenoid.

measure the resistance of the fuel sender as shown below.
3.
Allow the sender float to sit in the empty position and
compare to specification.
Fan Control Circuit Bypass Test
1.
Disconnect harness from coolant temperature sensor on
the engine cylinder head (see Chapter 4 for location).
2.
With the transmission in Park, start the engine. After a few
seconds, the fan should start running and the “Check
Engine” indicator should display on the instrument cluster.
This indicates all other components are working properly.
3.
If the fan does not run or runs slowly, check the fan motor
wiring, ground, motor condition and mechanical relay for
proper operation. Repair or replace as necessary. If the fan
runs with the sensor harness disconnected, but will not turn
on when the engine is hot, check the coolant temperature
sensor and connector terminals.

Whenever the vehicle is not used for a period of three months or
more, remove the battery from the vehicle, ensure that it's fully
charged, and store it out of the sun in a cool, dry place. Check
battery voltage each month during storage and recharge as
needed to maintain a full charge.
NOTE: Battery charge can be maintained by using a
Polaris battery tender charger or by charging once a
month to make up for normal self-discharge. Battery
tenders can be left connected during the storage
period, and will automatically charge the battery if
the voltage drops below a pre-determined point.

CAUTION
To prevent shock or component damage, remove spark

engine ground before proceeding.
Battery Testing
Whenever a service complaint is related to either the starting or
charging systems, the battery should be checked first.
Following are two tests which can easily be made on a sealed
Maintenance Free battery to determine its condition: OCV Test
and a Load Test.
OCV - Open Circuit Voltage Test
Battery voltage should be checked with a digital multitester.
Readings of 12.6 volts or less require further battery testing and
charging. See the following chart and “Load Test”.
A battery may indicate a full charge condition in the OCV test,
but still may not have the storage capacity necessary to properly
function in the electrical system. For this reason, a battery
capacity or load test should be conducted whenever poor battery
performance is encountered.
To perform this test, use a load testing device that has an
adjustable load. Apply a load of three times the ampere-hour
rating. At 14 seconds into the test, check battery voltage. A good
12V battery will have at least 10.5 volts. If the reading is low,
charge the battery and retest.
NOTE: Maintenance Free batteries should be kept at
a high state of charge during storage. If the battery is
stored or used at a low state of charge, hard crystal
sulfation will form on the plates, reducing the
efficiency and service life of the battery.
NOTE: Use a volt/ohm meter to test battery voltage.

Battery Conductance Analyzer
Conductance describes the ability of a battery to conduct
current. A conductance tester functions by sending a low
frequency AC signal through the battery and a portion of the
current response is captured, from this output a conductance
measurement is calculated. Conductance testing is more
accurate than voltage, specific gravity, or load testing.
Authorized Polaris dealers/distributors are required to use the
conductance analyzer when testing 12V Polaris batteries.
NOTE: Allow the battery to stand disconnected for
at least 1-2 hours after being properly charged. If the
voltage drops below 12.6 volts, charging was
ineffective or the battery needs to be replaced.
WARNING
An overheated battery could explode, causing severe
injury or death. Always watch charging times carefully.
Stop charging if the battery becomes very warm to the
touch. Allow it to cool before resuming charging.

ELECTRONIC POWER STEERING (EPS)
EPS 8-Way Wire Harness Connector
EPS Operation
The 8-way connector, two rows of four pins, does not have a
channeled lock on both sides, allowing it to be installed 180°
from its intended position. The connector will not positively
engage or snap into place while in the wrong position, but can
still be installed. If the connector is not installed correctly, the
Power Steering Unit will not function. This situation can be
avoided by paying close attention when installing the 8-way
connector. If the 8-way is connected properly, the vehicle should
have assist with the key on.
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 either cycle the key switch or start the engine to regain
power steering operation.

but not the Power Steering Controller, while using
Digital Wrench™.
READ BEFORE YOU REPLACE THE EPS UNIT!
IMPORTANT: Try to reflash the EPS unit before
attempting to replace it. A simple reflash may be all
that is needed to repair the EPS problem. Always
reflash the EPS unit as the first step in diagnosing an
EPS problem.
NOTE: DO NOT SPLICE OR CUT INTO THE CAN
CIRCUITS.
