How to Reset Check Engine Light on Can Am Outlander

If you’ve ever been riding your Can Am Outlander through a muddy trail or cruising down a forest path only to see that dreaded check engine light flash on your dashboard, you’re not alone. It’s a common experience for ATV owners—and while it can be alarming, it doesn’t always mean disaster. In many cases, the light is triggered by something minor, like a loose gas cap or a temporary sensor glitch. But before you panic or ignore it, it’s important to understand what the light means and how to properly address it.

In this comprehensive guide, you’ll learn how to reset the check engine light on a Can Am Outlander safely and effectively. We’ll cover multiple methods—from using your ATV’s built-in diagnostic system to using a scan tool or even disconnecting the battery. But more importantly, we’ll emphasize why you should never just reset the light without first diagnosing the root cause. Ignoring the problem could lead to reduced performance, poor fuel economy, or even serious engine damage down the road.

Whether you’re a weekend warrior or a full-time off-road enthusiast, this guide is designed to help you take control of your Outlander’s health. By the end, you’ll know exactly what steps to take, what tools you might need, and how to prevent future check engine warnings. Let’s get started.

Understanding the Check Engine Light on Your Can Am Outlander

Before jumping into the reset process, it’s crucial to understand what the check engine light actually means. On a Can Am Outlander, this warning light—often labeled “MIL” (Malfunction Indicator Lamp) or simply “Engine”—is part of the vehicle’s onboard diagnostic system (OBD2). When the engine control unit (ECU) detects a problem with the engine, emissions system, or related components, it stores a diagnostic trouble code (DTC) and illuminates the light to alert you.

Common triggers include:
– A loose or missing gas cap
– Faulty oxygen (O2) sensor
– Dirty or failing spark plugs
– Clogged air filter
– Malfunctioning fuel injector
– Electrical issues or wiring problems
– Exhaust gas recirculation (EGR) valve faults

The light may appear as a steady glow or flash. A steady light usually indicates a minor issue, while a flashing light suggests a more serious problem—such as engine misfiring—that could damage the catalytic converter if ignored.

It’s also worth noting that some Outlander models have a “Service” light in addition to the check engine light. The service light typically reminds you of scheduled maintenance (like oil changes), while the check engine light is specifically for mechanical or electrical faults.

Why You Shouldn’t Just Reset the Light Without Diagnosis

One of the biggest mistakes ATV owners make is resetting the check engine light immediately without investigating the cause. While it might be tempting to clear the light and hope it doesn’t come back, this approach is risky. The light is there for a reason—it’s your Outlander’s way of saying, “Hey, something’s not right.”

For example, if the light is on because of a failing oxygen sensor, simply resetting it won’t fix the sensor. The problem will persist, and the light will likely return within a few rides. Worse, a faulty O2 sensor can cause poor fuel efficiency, increased emissions, and engine performance issues over time.

Similarly, if the issue is a loose gas cap—a very common cause—resetting the light without tightening or replacing the cap means the fuel system remains unsealed, allowing fuel vapors to escape. This not only triggers the light again but also harms the environment and reduces fuel economy.

In short: Always diagnose the problem first. Use the check engine light as a starting point for troubleshooting, not just a nuisance to be silenced.

Method 1: Reset Using the Built-In Diagnostic Mode (No Tools Required)

The easiest and most recommended way to reset the check engine light on many Can Am Outlander models is by using the ATV’s built-in diagnostic menu. This method works on most 2013 and newer models with digital instrument clusters. It doesn’t require any special tools—just your hands and a few minutes of your time.

Step 1: Turn the Ignition to the “On” Position

Sit on your Outlander and turn the key to the “ON” position. Do not start the engine—just power up the electronics. You should see the dashboard lights illuminate, including the check engine light.

Step 2: Access the Diagnostic Menu

On most Outlander models, you can access the diagnostic menu using the buttons on the left handlebar or directly on the instrument cluster. Here’s how:
– Press and hold the “Mode” or “Menu” button (usually located near the speedometer).
– While holding it, turn the ignition to “ON.”
– Continue holding the button for about 5–10 seconds until the display changes.

You should now see a menu or code display appear on the screen.

Step 3: Navigate to the “Clear Codes” Option

Use the “Up” and “Down” buttons (or the same Mode button in a sequence) to scroll through the menu options. Look for something like:
– “Clear DTC”
– “Reset MIL”
– “Erase Codes”
– “Service Reset”

The exact wording may vary depending on your model year and firmware.

Step 4: Confirm the Reset

Once you’ve highlighted the “Clear Codes” option, press and hold the “Mode” button again (or follow the on-screen prompt) to confirm. You may see a message like “Codes Cleared” or “Reset Complete.”

Step 5: Turn Off the Ignition

After the reset is confirmed, turn the key back to the “OFF” position. Wait about 30 seconds, then turn it back to “ON” to check if the check engine light remains off.

If the light stays off, the reset was successful. If it comes back on immediately, the underlying issue hasn’t been resolved.

Tips for Success

– Make sure the battery is fully charged before attempting this method. Low voltage can interfere with the ECU.
– If the menu doesn’t appear, consult your owner’s manual—some models require a specific button sequence.
– This method only clears stored codes. It won’t fix mechanical problems.

Method 2: Using a Can Am-Compatible OBD2 Scan Tool

For more advanced diagnostics and reliable resets—especially on newer Outlander models (2018 and later)—using an OBD2 scan tool is the best approach. These tools plug into the ATV’s diagnostic port and communicate directly with the ECU, allowing you to read, interpret, and clear trouble codes with precision.

Step 1: Locate the OBD2 Port

On most Can Am Outlanders, the OBD2 port is located under the seat or near the battery compartment. It’s a 16-pin connector, similar to those found in cars. To access it:
– Remove the seat by unscrewing the bolts or releasing the latches.
– Look for a black plastic connector near the frame or battery tray.

If you can’t find it, check your owner’s manual—some models hide it behind a protective cover.

Step 2: Connect the Scan Tool

Plug your OBD2 scanner into the port. Make sure the ignition is in the “ON” position (engine off). The scanner should power up and display a menu.

Step 3: Read the Trouble Codes

Select “Read Codes” or “Scan” from the menu. The tool will retrieve any stored DTCs. Common codes on Outlanders include:
– P0171 – System too lean (bank 1)
– P0300 – Random/multiple cylinder misfire
– P0455 – Large EVAP leak (often a loose gas cap)

Write down the codes and research their meaning using the scanner’s built-in database or online resources.

Step 4: Fix the Underlying Issue

Before resetting, address the problem. For example:
– Tighten or replace the gas cap for EVAP codes.
– Replace spark plugs or coils for misfire codes.
– Clean or replace the air filter for lean condition codes.

Step 5: Clear the Codes

Once the issue is fixed, return to the scanner and select “Clear Codes” or “Erase DTCs.” Confirm the action. The scanner will send a command to the ECU to reset the check engine light.

Step 6: Verify the Reset

Turn the ignition off, wait 30 seconds, then turn it back on. The check engine light should remain off. Take your Outlander for a short test ride to ensure the problem is truly resolved.

Recommended Scan Tools

– Can Am BRP Diagnostic Tool (Genuine): The official tool used by dealers. Offers full system access but is expensive.
– Autel MaxiCOM MK808: Affordable, user-friendly, and compatible with Can Am models.
– Foxwell NT510: Great for ATVs and motorcycles, with multi-system diagnostics.

Method 3: Disconnecting the Battery (Last Resort)

If you don’t have access to a scan tool and the built-in menu method doesn’t work, you can try resetting the check engine light by disconnecting the battery. This method forces the ECU to reset by cutting power, but it’s not always reliable and comes with caveats.

Step 1: Turn Off the Ignition

Make sure the key is in the “OFF” position and remove it from the ignition.

Step 2: Disconnect the Negative Terminal

Using a wrench or socket, loosen the nut on the negative (black) battery terminal. Carefully remove the cable and tuck it away from the battery to prevent accidental contact.

Step 3: Wait 10–15 Minutes

Leave the battery disconnected for at least 10–15 minutes. This allows the ECU’s capacitors to fully discharge, clearing stored memory—including trouble codes.

Step 4: Reconnect the Battery

Reattach the negative cable and tighten the nut securely. Make sure the connection is clean and tight.

Step 5: Turn On the Ignition

Turn the key to “ON” and check if the check engine light is off. Start the engine and let it idle for a few minutes.

Important Notes

– This method may reset other systems, including radio presets, trip odometers, and learned fuel trims.
– Some newer Outlander models have backup power or non-volatile memory, so the reset may not work.
– If the light returns, the problem still exists—don’t repeat this method repeatedly.

Troubleshooting Common Issues

Even after following the steps above, you might encounter problems. Here’s how to handle common scenarios:

The Light Comes Back On After Reset

This means the underlying issue wasn’t fixed. Recheck the trouble codes using a scan tool or the built-in menu. Common recurring issues include:
– Faulty oxygen sensors
– Worn spark plugs
– Clogged fuel injectors
– Electrical shorts

The Built-In Menu Doesn’t Appear

Some older Outlander models (pre-2013) may not support the diagnostic menu. In this case, use a scan tool or battery disconnect method.

The Scan Tool Won’t Connect

Ensure the OBD2 port is clean and undamaged. Check that the scanner is compatible with Can Am ATVs. Some generic car scanners don’t work with ATVs.

The Battery Keeps Dying After Reconnecting

This could indicate a parasitic drain or a failing battery. Test the battery and charging system with a multimeter.

Preventing Future Check Engine Lights

The best way to avoid dealing with the check engine light is to prevent it from coming on in the first place. Regular maintenance is key.

Perform Routine Maintenance

– Change the oil and filter every 25–50 hours of use.
– Replace spark plugs every 100 hours or as recommended.
– Clean or replace the air filter regularly, especially after dusty rides.
– Inspect the fuel system for leaks or clogs.

Check the Gas Cap

After every fill-up, make sure the gas cap is tight. A loose cap is one of the most common causes of EVAP-related codes.

Use Quality Fuel and Oil

Low-quality fuel or incorrect oil can cause engine problems. Use ethanol-free gas and manufacturer-recommended oil.

Inspect Wiring and Sensors

Periodically check under the seat and around the engine for damaged wires, corroded connectors, or loose sensors.

When to See a Mechanic

While many check engine issues can be resolved at home, some problems require professional attention. Seek a certified Can Am technician if:
– The check engine light is flashing (indicating a severe misfire).
– You notice poor performance, stalling, or rough idling.
– The light returns immediately after reset.
– You’re unsure how to interpret or fix the trouble codes.

Ignoring serious issues can lead to costly repairs or engine failure.
