That blinking check engine light on your 2014 Polaris 570’s dash can kill the mood on a trail ride faster than a sudden downpour. It’s a frustrating sight that brings up questions of costly repairs and ruined weekends.
But don’t let it sideline your machine or force an expensive trip to the dealer just yet. We promise to show you exactly how to read, understand, and clear those pesky trouble codes right in your own garage, using the tools your Polaris already has built-in.
In this ultimate guide on how to clear codes on a 2014 polaris 570, we’ll walk you through the entire process. You’ll learn how to access the diagnostic mode, what the codes mean, the proper procedure for clearing them after a fix, and the critical reasons why you should never just erase a code and hope for the best. Let’s get you back on the trail with confidence.
Why You Shouldn’t Just Ignore That Check Engine Light
First things first, that little light is your friend. It’s the Engine Control Unit (ECU)—the brain of your machine—telling you it has detected a problem. These problems are stored as Diagnostic Trouble Codes, or DTCs.
Ignoring a code is like ignoring a rock in your boot. It might be a small annoyance now, but it can lead to a much bigger problem down the trail. A simple sensor fault could lead to poor fuel economy, while a misfire code could indicate an issue that might cause serious engine damage if left unchecked.
Understanding the benefits of how to clear codes on a 2014 polaris 570 is about more than just making a light go away. It’s the final step in confirming a successful repair, resetting the system, and ensuring your machine is running at peak performance and efficiency.
Before You Clear Anything: Reading the Codes is Step One
Clearing a code without knowing what it is is a cardinal sin in the mechanic’s world. You’re erasing the single most important clue to what’s wrong! Luckily, Polaris made it easy to read codes on your 2014 570 without any special tools.
This process uses the ignition key and the mode/override button on your gauge cluster. It might feel a bit like a video game cheat code, but it works like a charm.
Accessing the On-Board Diagnostic Mode
Follow these steps carefully to pull your active and stored trouble codes:
Turn the Ignition Key: Cycle the key from OFF to ON three times, leaving it in the ON position on the final turn. Do this in a steady rhythm: ON… OFF… ON… OFF… ON.
Wait for the Screen: The gauge cluster screen should start to cycle through any stored codes. If no codes are present, it will typically display “End”.
Read and Record: The codes will be displayed in a sequence. You’ll usually see an error code number followed by SPN and FMI numbers, which provide more specific details. Don’t try to memorize them—use your phone to take a picture or video of the screen as it cycles through.
Having a record of the exact codes is absolutely crucial. These numbers are your roadmap to a successful diagnosis and repair. A quick search online or in your service manual for that specific code will tell you what system is having a problem.
The Step-by-Step Guide: How to Clear Codes on a 2014 Polaris 570
Alright, you’ve read the codes and—most importantly—you’ve fixed the underlying issue. Maybe you replaced a fouled spark plug, cleaned a dirty sensor, or tightened a loose wire. Now, and only now, is it time to clear the code.
There are two primary methods to do this. The first is the “correct” way that relies on the ECU’s self-check system. The second is a “hard reset” that should be used more sparingly.
Method 1: The “Key Cycle” Fix (The Right Way)
The ECU on your Polaris is smart. Once you fix the problem, the system is designed to clear the “active” code on its own after it runs through a few checks and confirms the fault is gone. This is the most sustainable and eco-friendly how to clear codes on a 2014 polaris 570 method because it confirms the repair is valid.
A “key cycle” or “drive cycle” means starting the engine, letting it get up to full operating temperature, and then shutting it off. This allows the ECU to run all its sensor checks.
Confirm the Repair: Double-check that the issue causing the code has been fully resolved.
Start the Engine: Turn the key and let your 570 idle. Allow it to run long enough for the cooling fan to cycle on and off at least once. This ensures it’s at full operating temp.
Shut It Down: Turn the key completely off and let the machine sit for about 30 seconds.
Repeat: Perform this complete cycle 3 to 5 times. After several successful cycles where the ECU does not detect the original fault, it will typically clear the code itself, and the check engine light will turn off.
This is one of the most important how to clear codes on a 2014 polaris 570 tips: let the machine heal itself. If the light goes out using this method, you can be confident your fix worked.
Method 2: The Battery Disconnect (The Hard Reset)
Sometimes, a code can be “stuck” in the system’s memory, or you may want to clear everything and start fresh after a major repair. In this case, a battery disconnect can force a hard reset of the ECU.
Safety First: Always wear safety glasses and gloves when working with a battery.
Access the Battery: Locate your Polaris 570’s battery. It’s typically under the seat or a side panel.
Disconnect the Negative Terminal: Using the appropriate wrench (usually 10mm), loosen and remove the cable from the negative (-) battery terminal first. This is a critical safety step to prevent accidental shorts. Tuck the cable away so it can’t touch the terminal.
Wait: Let the machine sit with the battery disconnected for at least 15-20 minutes. This gives enough time for the capacitors within the ECU to fully discharge, erasing its temporary memory, which includes the fault codes.
Reconnect the Battery: Reconnect the cables in the reverse order. Attach the positive (+) cable first, then attach the negative (-) cable last. Ensure both are tight.
Start and Check: Turn the key on. The check engine light should be off. Start the engine and let it idle for a few minutes to allow the ECU to begin its “re-learning” process.
Common Problems & What Those Codes Might Mean
One of the most common problems with how to clear codes on a 2014 polaris 570 is that the code comes right back. This means the underlying issue was never fixed. Here are a few common codes you might see and what they generally point to:
Misfire Codes (e.g., 651, 652): These often point to a bad spark plug, a faulty ignition coil, or a problem with the plug wire. Start with the easiest and cheapest fix: a new spark plug.
Low Voltage Codes: This could be a sign of a weak battery, corroded terminals, or a failing stator or voltage regulator. Test your battery first.
Throttle Position Sensor (TPS) Codes: Often caused by a faulty sensor or a bad connection in the wiring harness leading to it. Check for any chafed or broken wires near the throttle body.
Overheating Codes: This could be low coolant, a bad radiator cap, a failing fan motor, or a blocked radiator. Make sure your radiator is clean and your coolant is topped off.
Best Practices: The FatBoysOffroad Care Guide to Code Management
Being a savvy owner means more than just knowing how to make a light go away. This how to clear codes on a 2014 polaris 570 care guide focuses on the right mindset and best practices for long-term machine health.
Don’t Be a “Code Clearer”
The code is a symptom, not the disease. The goal is never to just clear the code; the goal is to fix the problem that’s causing it. Clearing the code and continuing to ride is a recipe for disaster and will almost certainly lead to a more expensive repair later.
Know When to Call in a Pro
There’s no shame in knowing your limits. If you’ve tried the basic fixes and the code persists, or if you’re dealing with complex electrical or communication codes (CAN bus errors), it’s time to take it to a qualified technician. They have advanced diagnostic tools that can read live sensor data, which is often necessary to pinpoint tricky, intermittent problems.
Invest in a Service Manual
The single best tool you can buy for your Polaris is the official factory service manual. It contains detailed diagnostic procedures for every single trouble code, wiring diagrams, and component testing specs. It takes the guesswork out of the equation and is an invaluable resource for any serious DIYer.
Frequently Asked Questions About How to Clear Codes on a 2014 Polaris 570
Can I clear codes without fixing the problem?
Yes, you can temporarily clear them using the battery disconnect method. However, the code will come right back as soon as the ECU runs its self-check and detects the fault again, usually within minutes of starting the engine. It accomplishes nothing.
Do I need a special OBD-II scanner like for my car?
No. One of the great features of this model is the built-in diagnostic mode accessible via the key cycle method. While professional-grade diagnostic scanners exist for Polaris machines, you do not need one for basic code reading and clearing.
Will disconnecting the battery erase important engine data?
It will clear the active and stored fault codes and reset short-term learned values like fuel trims and idle settings. It will not erase the permanent engine map or critical programming. The ECU will re-learn the necessary parameters as you ride.
The code cleared but my Polaris still runs poorly. What now?
This is a strong indication that the problem is either mechanical (not sensor-related) or that the code you fixed was only one symptom of a larger issue. It’s time to go back to basics: check fuel pressure, inspect for vacuum leaks, and verify compression. The problem lies beyond what the ECU can detect.
Tackling a check engine light on your 2014 Polaris 570 is well within the reach of a DIYer. By following this how to clear codes on a 2014 polaris 570 guide, you can diagnose the issue, perform the repair, and confidently clear the code, knowing you did the job right.
Remember the golden rule: read first, fix second, and clear last. This approach will save you time, money, and frustration, keeping your machine running strong for years to come.
Now you’ve got the knowledge to be the master of your machine. Get those codes handled the right way, and get back on the trail where you belong. Ride safe!
