How To Clear Codes On Polaris RZR 1000: Step-by-Step

Clearing codes on Polaris RZR 1000 depends on the year model. So, before you start the process, you must go through your car manual. However, here I am providing a standard guideline to clear the codes.

Step 1. Access the ECU

To clear codes on your Polaris RZR 1000, you will need to access the ECU (Electronic Control Unit). This is usually done by plugging a diagnostic tool into the main wiring harness. The diagnostic tool can be used to read engine codes and reset them as needed.

Once you have accessed the ECU, you can begin the process of clearing codes on your Polaris RZR 1000. Be sure to check with a professional prior to making any changes, as incorrect settings could cause serious damage to your vehicle’s engine.

Step 2. Reset the ECU

The first step in clearing codes from the ECU is to reset it. To do this, locate and press the “Reset” button on your diagnostic tool. This will clear all stored engine codes and reset the ECU to its factory settings.

Remember, this process will not delete any codes that have been stored in the vehicle’s memory. You will need to use a separate diagnostic tool to clear those codes.

Step 3. Clear Codes from Memory

Once the ECU has been reset, you can clear codes from the memory of your Polaris RZR 1000. To do this, locate and press the “Clear” button on your diagnostic tool. This will delete all stored codes from memory and allow you to start fresh with a clean slate.

However, some ECUs may require you to enter the code numbers to clear them manually. If this is the case, refer to your owner’s manual for instructions on how to do this.

Step 4. Check the Results

Once you have cleared all codes from your Polaris RZR 1000, check the results. The best way to do this is to take a drive and run some diagnostics tests. 

Ensure all engine lights are off and no error codes are displayed on the instrument cluster. If everything looks good, your Polaris RZR 1000 is now ready for use.

Why You Should Clear Codes On Polaris RZR 1000?

There are so many reasons why clearing codes on Polaris RZR 1000 is necessary. Here they are-

1. Improved Performance

Clearing codes on your Polaris RZR 1000 can help improve engine performance. If a code has been stored in the ECU, it may cause the engine to run inefficiently. And this can lead to decreased power and poor fuel economy. Clearing these codes allows the engine to operate at its peak performance level.

2. No More Warning Lights

If a code has been stored in the ECU, it can cause warning lights to appear on your instrument cluster. This can be very distracting and potentially dangerous if you are out driving. By clearing these codes, you can ensure that all warning lights remain off while driving.

3. Keeps Your Vehicle Running Smoothly

Codes stored in the ECU can lead to malfunctioning parts or sensors, which can affect the overall performance of your vehicle. By clearing these codes, you can make sure that all components are working properly so that your Polaris RZR 1000 runs as smoothly as possible.

4. Enhanced Safety

When codes are stored in the ECU, you may be at a higher risk for problems such as brake failure or incorrect speedometer readings. Clearing these codes can help ensure that your Polaris RZR 1000 is safe to drive.

5. Improved Reliability

If the ECU is filled with codes, it can cause the vehicle to become unreliable. By clearing these codes, you can help ensure that your Polaris RZR 1000 is reliable for years to come.

What Happens If You Don’t Clear Codes On Polaris RZR 1000?

Failure to adequately clear codes on a Polaris RZR 1000 can lead to costly repair bills if not addressed promptly. If the codes are not cleared, they will remain stored in the ECU and can prevent your vehicle from running correctly. 

You may be able to start your engine. However, the vehicle will likely run sluggishly or unevenly. Additionally, any diagnostic tests done by an authorized dealer for potentially underlying issues may be inconclusive due to the presence of stored codes in the ECU.

Clearing codes is relatively uncomplicated for someone who is knowledgeable about engine settings. Thus, doing so without experience often results in further complications and can even void warranty coverage.

So, avoid costly repairs and extended periods without reliable transportation. Make sure to clear activation codes on your Polaris RZR 1000 as soon as possible with an expert’s help.

How Do You Reset The Maintenance Light On A Polaris RZR 1000?

Resetting the maintenance light on a Polaris RZR 1000 may seem intimidating, but fear not – it’s relatively simple. All it takes is a small screwdriver to remove the driver’s side service panel and access the power steering fuses located at the bottom.

Once you’ve removed the fuses, simply turn off your ignition switch and wait for 25 seconds until the maintenance light turns off. Then reinstall the power steering fuses and reattach the service panel, and you’re good to go!


There are so many questions when it comes to clearing codes on your Polaris RZR 1000. Here are some of the most frequently asked questions:

Q: Can you manually turn off the check engine light?

Yes, you can. The check engine light can be turned off by disconnecting the car’s battery or resetting its electronic control unit (ECU). 

Essentially, this reboots the computer and forces it to store its prior state. To achieve this, turn your key on in the ignition for a couple of seconds, then turn it back off, and repeat this process 3 or 4 times.

Q: Can you drive your Polaris RZR 1000 with an error code?

It is not advisable to drive your Polaris RZR 1000 with a stored error code in the ECU. Doing so could cause further damage to the vehicle and lead to an accident. 

Additionally, if these codes are not cleared, diagnostic tests performed by an authorized dealer may be inconclusive. So, clear the codes as soon as possible with help from a qualified expert.

Q: Does Polaris RZR 1000 use OBD-II?

Yes, the Polaris RZR 1000 uses the On-Board Diagnostic II (OBD-II) protocol. This is a generic system used by most automakers and allows mechanics to diagnose and repair a variety of problems. It also enables drivers to reset check engine lights and clear codes stored in their ECU.


Clearing codes on a Polaris RZR 1000 can be simple if done correctly. Make sure to follow the instructions outlined in this article. Do not attempt to clear codes without the help of a professional or an experienced technician.

However, it is always best practice to consult a professional before attempting any type of repair or maintenance on your Polaris RZR 1000.
