How To Clear Can Am Fault Codes – The Complete DIYER’S Guide

There’s nothing that kills the thrill of a ride faster than a warning light flashing on your Can-Am’s digital display. That dreaded check engine symbol or a cryptic fault code can pop up at the worst time, leaving you wondering if it’s a trail-ending disaster or just a minor hiccup. You know you need to deal with it, but the thought of a costly trip to the dealer is just as frustrating.

We’ve all been there. You’re miles from civilization, your machine beeps, and your heart sinks. But what if you had the power to understand what your Can-Am is trying to tell you and the confidence to handle it yourself?

This is your complete guide. We promise to walk you through exactly how to clear Can Am fault codes the right way. We’ll cover the tools you need, the safe step-by-step methods, and—most importantly—how to understand the root problem so you’re not just hitting a reset button on a serious issue. Let’s get you back in control and back on the trail.

Why You Shouldn’t Just Clear a Fault Code (And When It’s Okay)

Before we grab any tools, let’s get one thing straight: a fault code is a message, not the problem itself. Think of it as your Can-Am’s way of saying, “Hey, something’s not right over here!” Simply clearing the code without investigation is like silencing a smoke alarm without checking for a fire.

Ignoring the underlying issue can lead to more significant, more expensive damage down the road. A simple sensor fault could, if ignored, cause poor engine performance, terrible fuel economy, or even catastrophic failure.

So, When Is It Safe to Clear a Code?

There are legitimate times when clearing a code is the final step of a job well done. The primary benefits of how to clear can am fault codes are confirming a successful repair and restoring your machine to its normal operating state.

After a Successful Repair: You’ve diagnosed the code (e.g., a faulty O2 sensor), replaced the part, and now you need to clear the stored code to tell the ECU the problem is solved.
For an Intermittent “Soft Code”: Sometimes, a sensor can have a momentary glitch. A deep water crossing might trip a sensor, or a loose connection might briefly cause a fault. If the issue doesn’t return after a restart, clearing the historic code is often fine.
The “Loose Gas Cap” Scenario: On many vehicles, a loose gas cap can trigger an evaporative emissions (EVAP) system code. Once you tighten it, the code may need to be cleared manually.

Essential Tools for Tackling Can-Am Fault Codes

Having the right gear makes all the difference between a quick fix and a day of frustration. You don’t need a full dealership setup, but a couple of key items are non-negotiable for doing this job properly.

The OBD-II Scanner: Your Diagnostic Best Friend

An On-Board Diagnostics (OBD-II) scanner is the most important tool in your arsenal. It plugs into your Can-Am’s diagnostic port and communicates directly with its computer (ECU). It reads the specific code, gives you a description, and allows you to erase it.

While a generic automotive scanner might work, we highly recommend a powersports-specific model from brands like CandooPro or MaptunerX. These are designed to understand the unique language of BRP products. The dealer-level tool is called BUDS2, but these aftermarket options give you incredible power for a fraction of the cost.

The 6-Pin to 16-Pin Adapter Cable

This is the missing link for many DIYers. Your Can-Am has a 6-pin diagnostic port, but most OBD-II scanners have a 16-pin plug. You absolutely need a Can-Am specific adapter cable to connect the two. Don’t even start the job without one.

Basic Hand Tools

You may not need them to clear the code itself, but you’ll need them for the repair that the code points to. Keep a good set of sockets, wrenches, and screwdrivers handy.

How to Clear Can Am Fault Codes: The Step-by-Step Guide

Alright, you’ve got your tools and you understand the “why.” Now it’s time for the “how.” Here are the most effective methods, from the professional-grade to the field-expedient. This is your ultimate how to clear can am fault codes guide.

Method 1: Using an OBD-II Diagnostic Scanner (The Recommended Way)

This is the safest and most informative method. It allows you to see the problem before you erase the evidence.

Locate the Diagnostic Port: On most modern Can-Am models like the Maverick X3, Defender, and Outlander, the 6-pin port is located under the dashboard on the driver’s side or near the ECU/fuse box area. It often has a black or red dust cap.
Connect Your Gear: Plug the 6-pin end of your adapter cable into the Can-Am’s port. Then, connect the 16-pin end to your OBD-II scanner.
Power Up: Put the key in the ignition and turn it to the “ON” position, but do not start the engine. The dashboard should light up.
Read and Record the Codes: Power on your scanner and follow its menu prompts to “Read Codes” or “Scan for DTCs” (Diagnostic Trouble Codes). It’s critically important to write down the code number (e.g., P0135) and its description. Take a picture with your phone!
Diagnose the Problem: Use the code you recorded to research the issue. A quick search online for “Can-Am code P0135” will point you toward a potential O2 sensor heater circuit malfunction. This is the real work.
Perform the Repair: Based on your diagnosis, fix the underlying problem. This could be anything from tightening a loose wire to replacing a faulty sensor.
Clear the Code: Once the repair is complete, navigate your scanner’s menu to the “Erase Codes” or “Clear DTCs” option. The scanner will ask for confirmation. Select “Yes.”
Verify the Fix: Turn the ignition off, then start the engine. The check engine light should be off. Take it for a short ride to ensure the code doesn’t immediately return.

Method 2: The “Battery Disconnect” Reset (Use with Caution)

This is an old-school hard reset. It can sometimes clear minor, “soft” codes, but it’s a blunt instrument and won’t erase many serious, stored faults. It’s a last resort if you don’t have a scanner.

Turn off the vehicle completely and remove the key.
Using a wrench, disconnect the negative (-) battery terminal first for safety.
Let the vehicle sit disconnected for at least 15-30 minutes. This allows the capacitors in the ECU to fully discharge, clearing its temporary memory.
Reconnect the negative battery terminal and ensure it’s tight.
Start your Can-Am. If the code was temporary, the light may be off. If the problem is still present, the light will come back on almost immediately.

Common Problems with How to Clear Can Am Fault Codes

Even with the right tools, you can hit a snag. Here are some of the most common problems with how to clear can am fault codes and how to troubleshoot them.

The Fault Code Comes Right Back

This is the most common issue, and the answer is simple: the underlying problem is not fixed. The ECU runs a self-check, immediately detects the same fault, and re-triggers the code. You didn’t fail to clear the code; you failed to fix the reason for it. Go back to step 5 of the scanner method and diagnose more deeply.

My Scanner Won’t Connect or Power On

If your scanner isn’t communicating with the vehicle, check these things first:

Check the Fuse: The diagnostic port is often on a shared circuit. Check your fuse box for a blown fuse, often labeled “DIAG,” “ACC,” or “ECM.”
Verify Connections: Ensure the adapter cable and scanner are firmly plugged in at both ends.
Key Position: Double-check that the ignition is in the “ON” position. The ECU needs power to communicate.

The Machine Is Stuck in “Limp Mode”

Limp Mode is a protective state where the ECU drastically reduces power to prevent engine damage. If your Can-Am is in Limp Mode due to a serious fault, clearing the code with a scanner may not exit Limp Mode until the ECU confirms the fault is truly gone. This is a safety feature, and it means you have a serious issue that needs immediate attention.

How to Clear Can Am Fault Codes: Best Practices for a Sustainable Ride

Being a responsible owner goes beyond just fixing things. A smart diagnostic approach is also a sustainable one. Following a proper how to clear can am fault codes care guide ensures your machine runs cleanly and efficiently for years to come.

The most sustainable how to clear can am fault codes practice is to fix the root cause correctly the first time. Throwing parts at a problem is wasteful and expensive. Proper diagnosis prevents you from replacing perfectly good components.

Furthermore, many fault codes are related to emissions and engine efficiency. A faulty oxygen sensor, for example, can cause your engine to run rich, wasting fuel and increasing pollution. Fixing it isn’t just good for your machine; it’s a more eco-friendly how to clear can am fault codes approach that reduces your environmental footprint on the trails we all love.

Frequently Asked Questions About How to Clear Can Am Fault Codes

Can I clear a “Maintenance Required” message the same way?

Usually, no. The “Maintenance Required” or oil life reminder is not a fault code. It’s a simple timer set by the manufacturer. You can typically reset this message through a specific sequence of button presses on your digital dashboard display. Check your owner’s manual for the exact procedure for your model.

Will clearing fault codes void my Can-Am warranty?

Simply reading and clearing a code will not void your warranty. However, if you clear a code for a serious problem (like low oil pressure), continue to ride the machine, and cause major engine damage as a result, BRP could deny the warranty claim. The key is to use the information from the code to seek a proper repair, whether DIY or at the dealer.

What’s the difference between an active and a stored code?

An active code means the fault is happening right now. A stored or historic code means the fault occurred in the past but may not be currently present. A good scanner can often distinguish between the two, which is incredibly helpful for diagnosing intermittent issues.

Do I need the expensive BUDS2 system to clear codes?

No. For reading and clearing standard engine and system fault codes, a quality aftermarket scanner like a CandooPro or MaptunerX, paired with the correct adapter, is more than sufficient for any DIY mechanic. The BUDS2 system is only necessary for more advanced functions like key programming or module flashing.

Understanding how to tackle fault codes demystifies your machine and empowers you as an owner. It transforms a moment of panic into a manageable challenge. Remember the golden rule: diagnose first, repair second, and clear the code last. This approach will save you time, money, and keep your Can-Am running strong for countless adventures.

Now you’ve got the knowledge. Grab your tools, be smart, and get back on the trail. Ride safe out there!
