That pesky check engine light is mocking you again. Your dash lights are called “idiot lights” for a reason, and you’re not going to be caught dead at the park without resetting your Polaris RZR 1000’s check engine light first.
OK, maybe it’s not that bad, but a check engine light that doesn’t go away is annoying either way. Fear not! We’ll give you some sure-fire ways to get rid of a check engine light that’s stuck like a YXZ in mud.
When your check engine light comes on, you have a problem. And you’re not going to reset your check engine light without fixing that problem. Here’s how to figure out what the issue is:
Nine times out of ten, the issue is belt related. If you’re not sure how to fix whatever your issue is, find a dealer.
If your RZR’s check engine light doesn’t reset after fixing the problem, then you need to try another trick.
If your RZR’s check engine light doesn’t reset, it doesn’t necessarily mean you did something wrong. Your UTV might just need some time to sort itself out.
The length of time required to reset your light depends on the diagnostic code you get, and it’s hard to tell which ones will take longer.
With some codes, the check engine light will reset after 4000 engine revolutions (assuming the issue is fixed). Others will take much longer and require many key-on and off cycles.
And there are some that won’t reset with this method at all and require specialized tools.
If your RZR’s check engine light doesn’t reset on it’s own, you can try using specialized tools.
There are a number of tuners and other scan tools on the market that can manually reset your check engine light.
If you don’t have one, don’t want to get one, or it doesn’t work for you, you may have a code that can only be reset using Polaris’ proprietary “Polaris Digital Wrench Software.” Your local Polaris dealer should have access to this software and be able to reset your light in this case.
If you’ve tried everything else and can’t get your check engine light to go away, you’ll have to take it to a dealer.
If you’re at your wits’ end, and you have to get that check engine light off RIGHT NOW, there’s one more thing you can try.
Before we tell you what to do, we’ll tell you why we consider it a last resort. This process resets your ECU, but it can inadvertently reset parts of your ECU’s memory. It can lead to more issues. Some are easy to resolve, but others might require you to replace your ECU if it’s permanently damaged.
In theory, this is a risky method. In practice, it seems to work out.
To reset the ECU, you have to disconnect the battery completely. Then touch your RZR’s wire harness terminals together. This will drain the capacitors and anything else in your ECU that holds a charge, and is a guaranteed method of resetting your Polaris RZR’s check engine light.
With your idiot light situation resolved, you can ride with confidence knowing you’re just as mechanically intelligent as the next person. And when your buddy’s check engine light turns on, you can save the day.
Since 90% of check engine lights are caused by belt issues, make sure to upgrade your drive belts, and say goodbye to your idiot lights.
