You’re geared up for a day on the trails, you turn the key on your 2015 Sportsman, and there it is—the dreaded check engine light. A quick check of the diagnostic menu reveals code 1268. Worse, you notice the handlebars feel incredibly heavy, like you’re trying to turn a tank. That easy, one-handed steering you love is gone, replaced by a serious arm workout.
We’ve all been there. A sudden fault code can kill the mood and leave you wondering about expensive repair bills. But don’t load it onto the trailer just yet.
I promise this guide will walk you through exactly what the 2015 Polaris Sportsman code 1268 means, what causes it, and how you, a DIY mechanic, can troubleshoot it right in your own garage. We’ll cover everything from simple battery checks to inspecting the wiring, giving you the confidence to pinpoint the problem and get back to riding.
What Exactly is Fault Code 1268 on Your Sportsman?
First things first, let’s decode the message your ATV is sending. Code 1268 points directly to a problem within the Electronic Power Steering (EPS) system. This isn’t just a minor inconvenience; it’s a critical safety system that makes your machine manageable, especially in tight, technical terrain.
When this code appears, the machine’s computer (ECU) has detected an electrical fault and, as a safety measure, has shut down the power steering motor. This is why your steering suddenly becomes incredibly stiff. You’re now turning the wheels with pure muscle, just like on an older, non-EPS model.
You’ll often see this code with an accompanying FMI (Failure Mode Identifier) number, which gives you more clues:
- SPN 1268, FMI 2: Data Erratic, Intermittent, or Incorrect. The ECU is getting signals from the EPS unit that don’t make sense. This often points to a poor connection or electrical interference.
- SPN 1268, FMI 4: Voltage Below Normal, or Shorted to Low Source. This is the most common one. It means the EPS unit isn’t getting the stable voltage it needs to operate, usually due to a weak battery, bad connection, or wiring issue.
Understanding this is the first step in our diagnostic journey. This isn’t just a random glitch; it’s a specific call for help from a vital component of your ride.
Before You Grab a Wrench: Essential Tools & Safety First
A good mechanic never rushes in. Taking a few minutes to gather the right tools and think about safety will make the entire process smoother and prevent bigger headaches. You don’t need a full professional shop, just a few key items.
Here’s your diagnostic toolkit:
- Digital Multimeter: This is non-negotiable. You must have one to accurately test voltage and continuity. A basic one from any auto parts store will do the job.
- Socket Set & Wrenches: You’ll need these for battery terminals and potentially removing plastic panels to access wiring.
- Battery Terminal Brush: A cheap but invaluable tool for cleaning corrosion off posts and clamps.
- Dielectric Grease: Perfect for protecting electrical connections from moisture and corrosion once you’re done.
- Flashlight or Headlamp: You’ll be looking into dark corners of the machine’s frame, so good lighting is key.
- Zip Ties: For tidying up any wiring you move around.
Before you start, always put safety first. Work on a level surface, ensure the machine is in park, and always disconnect the negative battery terminal before you start unplugging electrical connectors. This prevents accidental shorts that could cause even more damage.
The Most Common Problems with 2015 Polaris Sportsman Code 1268 (And How to Fix Them)
Alright, let’s get our hands dirty. The key to how to solve the 2015 Polaris Sportsman code 1268 is to work methodically from the simplest, most common causes to the more complex ones. Don’t assume the worst right away. More often than not, the fix is easier than you think.
Step 1: The Power Source – Check Your Battery and Charging System
The EPS motor is a power-hungry beast. It needs a strong, stable supply of at least 12 volts to function. The slightest drop in voltage can trigger code 1268, making this the absolute first place you should look.
Grab your multimeter and set it to DC Volts.
- Static Voltage Test: With the key off, touch the multimeter probes to the battery terminals (red to positive, black to negative). A healthy, fully charged battery should read 12.6V or higher. If you see anything under 12.4V, your battery is weak and needs charging.
- Cranking Test: Reconnect the battery. Have a friend watch the multimeter as you crank the engine. The voltage should not drop below 9.6V. If it does, your battery is likely failing and can’t deliver the necessary amperage.
- Running Voltage Test: Start the ATV and let it idle. At idle, the voltage at the battery should jump up to 13.5V to 14.5V. This tells you the machine’s charging system (stator and voltage regulator) is working. If the voltage doesn’t increase, you have a charging system problem that needs to be addressed first.
If your battery fails any of these tests, charge it fully and test again. If it still fails, replace it. A weak battery is the number one cause of this code.
Step 2: Connection Inspection – The Low-Hanging Fruit
Electricity can’t flow through dirt and corrosion. The next step is to trace the power from the battery and ensure every connection is clean and tight. This is a crucial part of any good 2015 Polaris Sportsman code 1268 care guide.
Start by disconnecting the negative battery terminal. Then, remove the positive terminal. Use your wire brush to scrub the battery posts and the inside of the terminal clamps until they are shiny. Reconnect everything tightly.
Next, find the main ground wire where it connects from the battery’s negative terminal to the ATV’s frame. Unbolt it, clean the contact point on the frame and the wire’s terminal with a wire brush or sandpaper, and bolt it back down securely.
Step 3: The EPS Connector and Wiring Harness Deep Dive
Now it’s time to inspect the direct connection to the EPS unit. The unit is typically located under the front plastics, near the steering stem. You’ll see a large wiring harness plugging into it.
Carefully unplug this main connector. Look inside both ends with your flashlight. Are any of the metal pins green with corrosion? Are any bent or pushed back into the connector? Is there any sign of mud or water inside?
If you see corrosion, clean it carefully with an electronics cleaner and a small brush. If a pin is bent, you can gently try to straighten it with a small pick. Once clean and dry, apply a small amount of dielectric grease before plugging it back in. This will help seal it from future moisture.
Finally, trace the wiring harness as far as you can in both directions. Look for areas where it might be rubbing against the frame, pinched by a plastic panel, or melted by the exhaust. Any damage to the insulation can cause a short and trigger the code.
A Deeper 2015 Polaris Sportsman Code 1268 Guide: Testing the Circuit
If the battery, connections, and visual inspection check out, the next step is for the more confident DIYer. We’re going to use our multimeter to confirm power is actually reaching the EPS unit.
Disclaimer: For specific pin layouts and wire colors, a factory service manual for your machine is highly recommended.
With the main EPS connector unplugged and the key on, you can test for power. Typically, there will be a heavy-gauge red wire and a heavy-gauge black wire.
- Power Check: Set your multimeter to DC Volts. Touch the red probe to the terminal for the main power wire in the harness and the black probe to a good frame ground. You should see battery voltage (12V+).
- Ground Check: Set your multimeter to Continuity mode (it usually has a beep symbol). Touch one probe to the main ground wire’s terminal in the harness and the other probe to the negative battery terminal. It should beep, indicating a solid ground connection.
If you don’t have power or ground at the connector, you have a break in the wire somewhere between the EPS unit and the battery. You’ll have to carefully trace that specific wire to find the fault.
When to Suspect a Faulty EPS Unit
This is the step we hope we don’t get to. If you have confirmed your battery is strong, your charging system works, and you have clean, solid power and ground right at the EPS connector, then the problem is likely internal to the EPS unit itself.
Unfortunately, these units are sealed and generally not serviceable. Replacement is the only option. This is an expensive part, which is why it’s so important to follow all the previous 2015 Polaris Sportsman code 1268 tips to rule out every other possibility first.
If you reach this conclusion, you can take comfort in knowing you performed a thorough diagnosis and will save money on shop labor by telling your mechanic exactly what needs to be replaced.
