There’s nothing that kills the thrill of a trail ride faster than a flashing check engine light on your dash. You see that dreaded orange glow, your power steering suddenly feels like you’re wrestling a bear, and a cryptic code appears: 2017 polaris rzr 900s code 6565 13 2. Your heart sinks. Is this a trip-ending disaster? Is it going to cost a fortune at the dealership?
I’ve been there, and I can tell you that more often than not, this code is something you can absolutely tackle yourself with a few basic tools and a bit of know-how. That flashing light isn’t a death sentence for your RZR; it’s a message, and I’m here to help you translate it.
In this complete guide, we’re going to demystify code 6565 13 2. We’ll break down what it means, show you the most common culprits (hint: it’s often simpler than you think), and walk you through a step-by-step diagnostic process to get you back on the trail, fast. Let’s get those hands dirty and save you a trip to the shop.
What Code 6565 13 2 is Actually Telling You
First things first, let’s decode that number. Polaris, like most modern vehicle manufacturers, uses a standardized system for its fault codes. This isn’t just a random number; it’s a specific message from your RZR’s brain, the Engine Control Unit (ECU).
The code `6565 13 2` breaks down like this:
- SPN 6565: This stands for Suspect Parameter Number. 6565 points directly to the EPS Relay Output Driver. In simple terms, this is the circuit that controls the relay for your Electronic Power Steering (EPS).
- FMI 13: This is the Failure Mode Identifier. 13 means “Out of Calibration.” The ECU is seeing a signal from the EPS system that doesn’t make sense or falls outside the expected range.
- 2: This is just an occurrence counter, telling you how many times this fault has been logged. It’s not critical for our diagnosis.
So, when you put it all together, code 6565 13 2 means your RZR’s ECU has detected that the power steering control circuit is out of calibration. This almost always results in the ECU shutting down the power steering system as a safety precaution, which is why your steering suddenly becomes incredibly heavy.
The Usual Suspects: Common Problems with 2017 Polaris RZR 900s Code 6565 13 2
Before you start thinking you need to replace the entire expensive EPS unit, take a deep breath. In my experience, this code is rarely caused by a major component failure. It’s almost always a foundational electrical issue. Here are the most common culprits, from most likely to least.
The Number One Culprit: Low Battery Voltage
If you take away only one thing from this guide, let it be this: Polaris electrical systems hate low voltage. The EPS unit draws a lot of power, especially on startup. If your battery is weak, old, or just low on charge, the voltage can dip too low when you turn the key.
This voltage sag confuses the sensitive electronics, including the EPS module, causing it to throw a calibration fault code. This is, by far, the most frequent cause of code 6565 13 2.
Corroded Connections and Bad Grounds
Your RZR lives a tough life of mud, water, and vibrations. This is the perfect recipe for corrosion on electrical terminals and for ground connections to work themselves loose. A poor connection acts like a bottleneck for electricity, causing voltage drops and erratic signals that can easily trigger this EPS fault.
A Failing EPS Relay
The code specifically mentions the “EPS Relay Output Driver.” Sometimes, the problem is as simple as the relay itself. Relays are small electromagnetic switches that can wear out or fail over time, especially when exposed to the elements. Luckily, this is a cheap and easy part to test and replace.
The EPS Unit Itself (Less Common)
While possible, a complete failure of the main EPS unit is the least likely cause. It’s a sealed and robust component. Always exhaust every other possibility—battery, wiring, grounds, and relay—before you even consider condemning the expensive power steering unit.
Your Diagnostic Toolkit: Gear Up for the Fix
You don’t need a full professional shop to tackle this job. A few essential tools will get you through 99% of the diagnostics for this code. This is a crucial part of our 2017 polaris rzr 900s code 6565 13 2 guide.
- Digital Multimeter: This is non-negotiable. You cannot guess at voltage. A basic multimeter is your best friend for accurately diagnosing electrical problems.
- Socket and Ratchet Set: You’ll need this for battery terminals and checking ground bolts (typically 8mm, 10mm, and 13mm sockets are common).
- Wire Brush: A small stainless steel or brass brush is perfect for cleaning corrosion off battery terminals, ground points, and connector pins.
- Dielectric Grease: This is a must-have for any off-roader. It’s a non-conductive grease that seals out moisture and prevents future corrosion on electrical connections.
- Contact Cleaner: An aerosol can of electrical contact cleaner is great for flushing dirt and grime out of connectors before applying dielectric grease.
How to Fix 2017 Polaris RZR 900s Code 6565 13 2: A Step-by-Step Guide
Alright, let’s get to work. Follow these steps in order. Do not skip a step, as the most common fix is right at the beginning. This is the core of how to 2017 polaris rzr 900s code 6565 13 2 diagnostics.
Step 1: Safety First – Prepare Your Workspace
Before you do anything, ensure your RZR is on level ground with the transmission in Park and the parking brake set. Turn the ignition completely off and remove the key. Safety is always priority one.
Step 2: The Critical Voltage Check
Grab your multimeter. Set it to DC Volts (a “20” on the dial is usually perfect).
- Static Voltage: Touch the red probe to the positive (+) battery terminal and the black probe to the negative (-) terminal. A fully charged, healthy battery should read 12.6V or higher. Anything below 12.4V is a sign of a weak battery that needs charging or replacement.
- Cranking Voltage: Have a friend turn the key to start the RZR while you keep the probes on the terminals. The voltage should not dip below 10.5V. If it does, your battery is failing under load and is almost certainly the cause of your problem.
- Running Voltage: Start the RZR. At idle, check the voltage again. You should see between 13.8V and 14.4V. This tells you the charging system (stator and voltage regulator) is working. If it’s below 13.5V, you may have a charging issue compounding the problem.
If your battery fails any of these tests, stop right there. Charge or replace the battery before proceeding. This simple step solves the problem for most people.
Step 3: Inspect All Key Electrical Connections
If the battery checks out, it’s time to hunt for a bad connection. Disconnect the negative battery terminal first.
- Battery Terminals: Remove both cables and scrub the battery posts and the inside of the cable terminals with a wire brush until they are shiny.
- Frame Ground: Follow the main negative battery cable to where it bolts to the RZR’s frame. Unbolt it, and scrub the terminal and the frame contact point until you see bare, shiny metal.
- EPS Connector: The EPS unit is typically located under the dash, high up on the firewall. Locate its main electrical connector. Unplug it and look for any green or white crusty corrosion, or any pins that look bent or pushed back.
- Fuse/Relay Box: Open the fuse box and look for any signs of corrosion, dirt, or moisture.
After cleaning each connection, apply a thin layer of dielectric grease before reassembling. This is a key part of any good 2017 polaris rzr 900s code 6565 13 2 care guide.
Step 4: Test the EPS Relay
In your fuse box, locate the EPS relay. It should be labeled on the cover. A quick and easy test is to swap it with an identical relay from the same fuse box, like the fan or headlight relay. Make sure the part numbers on top of the relays match.
If you swap the relays and your power steering starts working (but your fan, for example, stops), you’ve found the problem. A new relay is an inexpensive fix.
Step 5: Clear the Code and Test Ride
With all connections cleaned and the battery confirmed healthy, it’s time to clear the code. The simplest way is to leave the negative battery cable disconnected for about 15-20 minutes. This will reset the ECU.
Reconnect the battery (positive first, then negative). Start your RZR and see if the check engine light and code are gone. Turn the steering wheel from lock to lock. If all feels good, take it for a short, slow test ride to confirm the fix is holding.
Best Practices to Prevent Future EPS Codes
Fixing the problem is great, but preventing it is even better. Adopting these 2017 polaris rzr 900s code 6565 13 2 best practices will save you headaches down the road.
Maintain a Healthy Battery
The single best thing you can do is use a battery tender or smart charger whenever your RZR is parked for more than a week. This keeps the battery at optimal voltage and dramatically extends its life.
The Power of Dielectric Grease
Make it a habit. Any time you have an electrical connector apart for any reason, add a dab of dielectric grease before you put it back together. It’s cheap insurance against the moisture that plagues every off-road machine.
Eco-Friendly Repair: Why Fixing is Better Than Replacing
One of the hidden benefits of this methodical approach is that it’s a sustainable one. By cleaning a ground or replacing a $10 relay, you avoid unnecessarily replacing a complex and expensive EPS unit. This eco-friendly 2017 polaris rzr 900s code 6565 13 2 approach is better for the planet and your wallet.
When to Wave the White Flag: Calling a Pro
There is no shame in knowing your limits. If you have performed all the steps above—you have a confirmed healthy and fully charged battery, you’ve cleaned every key connection, and the code still comes back immediately—it may be time to call for backup.
The issue could be a break in the wiring harness or a genuine internal fault in the EPS unit that requires a dealer’s advanced diagnostic tool, called “Digital Wrench,” to perform a forced recalibration or pinpoint the failure. Don’t just throw parts at it; at this point, a professional diagnosis is the most cost-effective next step.
Frequently Asked Questions About the 2017 Polaris RZR 900s Code 6565 13 2
Can I still ride my RZR with code 6565 13 2 active?
Technically, yes, the machine will run. However, you will have no power steering. At low speeds, this makes steering extremely difficult and fatiguing. At high speeds, it can be downright dangerous, as you won’t be able to make quick, corrective steering inputs. We strongly advise against riding until the issue is resolved.
Will a new battery automatically fix this code?
Often, yes. If low voltage was the root cause, installing a new, fully charged battery will provide the stable power the EPS unit needs. However, the fault code may remain stored in the ECU until you clear it by disconnecting the battery for 15-20 minutes.
Where is the EPS unit located on a 2017 RZR 900s?
You will find the Electronic Power Steering unit mounted under the dashboard, typically high up on the vehicle’s firewall, behind the instrument cluster. You’ll need to remove the hood and possibly a dash panel to get a clear view of it and its connectors.
