Before diving into diagnostics, it’s important to understand what the check engine light actually means. Unlike a simple low-fuel warning, the check engine light—also known as the Malfunction Indicator Lamp (MIL)—is part of your ATV’s onboard diagnostics system (OBD2). When sensors detect a problem with the engine, emissions, fuel system, or transmission, the Engine Control Unit (ECU) stores a trouble code and triggers the light.

There are two types of check engine light signals to watch for:

  • Solid Light: This means a fault has been detected, but it’s not currently causing immediate damage. You should diagnose and fix the issue soon.
  • Flashing Light: This is serious. It usually indicates a severe misfire that can damage the catalytic converter. Stop riding immediately and diagnose the problem.

The Can Am Outlander, especially newer 2024–2026 models, comes with advanced electronics and sensor networks. This means more precise diagnostics—but also more potential trouble codes. Common causes include dirty air filters, faulty oxygen sensors, loose gas caps, or worn spark plugs.

Method 1: Reading Flash Codes Using the Instrument Cluster

One of the easiest ways to check engine light codes on your Can Am Outlander is by using the built-in flash code system. This method requires no special tools—just your ATV’s dashboard and a little patience. It works on most Outlander models from 2015 onward, including the 2026 lineup.

Step 1: Turn the Ignition On (Do Not Start the Engine)

Sit on your Outlander and turn the key to the “ON” position. You’ll see the dashboard light up, and the check engine light should illuminate for a few seconds as part of the system check. Do not start the engine yet.

Step 2: Observe the Check Engine Light

Watch the check engine light closely. If a trouble code is stored, the light will begin to flash in a specific pattern. These flashes represent digits in a two-digit code.

For example:

  • A long flash followed by two short flashes = Code 12
  • Three long flashes and four short flashes = Code 34

Each flash sequence corresponds to a specific diagnostic trouble code (DTC). The light will repeat the sequence several times, then pause before repeating.

Step 3: Count the Flashes and Record the Code

Use a notepad or your phone to record the flash pattern. Count the long flashes first (each represents a tens digit), then the short flashes (units digit). Wait for the full sequence to repeat to confirm accuracy.

Tip: Some riders find it helpful to have a friend watch the light while they focus on counting.

Step 4: Look Up the Code

Once you have the code, refer to the Can Am Outlander service manual or a reliable online DTC database. Common flash codes include:

  • Code 12: No RPM signal from crankshaft sensor
  • Code 13: Oxygen sensor circuit malfunction
  • Code 21: Engine coolant temperature sensor issue
  • Code 43: Fuel injector circuit problem

Note: Flash codes are limited and may not provide as much detail as a scan tool. They’re best for basic diagnostics.

Method 2: Using a Scan Tool for Detailed Diagnostics

For more accurate and comprehensive results, a scan tool is the way to go. In 2026, scan tools have become more affordable and user-friendly, making them a smart investment for any serious ATV owner.

Step 1: Choose the Right Scan Tool

Not all OBD2 scanners work with Can Am ATVs. You’ll need one that supports Can-Am’s proprietary communication protocols. Here are your best options:

  • BRP Diagnostic Tool (BDT): The official tool used by dealers. It provides full access to all systems, including engine, transmission, and ABS. It’s expensive but highly accurate.
  • Bluetooth OBD2 Scanners (e.g., BlueDriver, OBDLink MX+): These plug into the OBD2 port and connect to your smartphone via an app. They’re more affordable and work well for basic engine codes.
  • Universal ATV Scanners (e.g., ANCEL AX300): Designed for powersports vehicles, these offer better compatibility than car-only scanners.

Tip: Check compatibility with your specific Outlander model and year before purchasing.

Step 2: Locate the OBD2 Port

On most Can Am Outlander models (2018–2026), the OBD2 port is located under the seat or near the front of the frame, close to the battery. It’s a 16-pin trapezoidal connector, similar to those in cars.

To access it:

  • Lift the seat using the release lever.
  • Look for a black plastic connector with a cap.
  • Remove the cap and plug in your scan tool.

Step 3: Connect the Scan Tool and Power On

Insert the scan tool into the OBD2 port. Turn the ignition to the “ON” position (do not start the engine). The scan tool should power up and establish a connection with the ECU.

If using a Bluetooth scanner, open the companion app on your phone and pair the device. Follow the on-screen prompts to initiate a scan.

Step 4: Read the Trouble Codes

Once connected, select “Read Codes” or “Scan for DTCs” from the menu. The tool will retrieve all stored trouble codes from the ECU.

Codes will appear in the standard OBD2 format, such as:

  • P0300: Random/Multiple Cylinder Misfire Detected
  • P0171: System Too Lean (Bank 1)
  • P0420: Catalyst System Efficiency Below Threshold
  • P0128: Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature)

Each code includes a description and often suggests possible causes.

Step 5: Interpret the Codes

Understanding what the codes mean is key to fixing the problem. Here’s a breakdown of common Can Am Outlander codes:

  • P0300 (Misfire): Often caused by bad spark plugs, clogged fuel injectors, or a dirty air filter. Check and replace spark plugs every 100 hours of operation.
  • P0171 (Lean Fuel Mixture): Could indicate a vacuum leak, dirty mass airflow sensor, or clogged fuel filter. Inspect intake boots and clean the air filter.
  • P0420 (Catalyst Efficiency): Usually means the catalytic converter is failing or there’s a persistent misfire. This may require professional diagnosis.
  • P0128 (Coolant Thermostat): The engine isn’t reaching proper operating temperature. Check the thermostat and coolant level.

Use the scan tool’s built-in code library or search online for “Can Am Outlander P0300 fix” for model-specific advice.

Method 3: Using a Smartphone App with Bluetooth Scanner

In 2026, smartphone integration has made ATV diagnostics more accessible than ever. With a Bluetooth OBD2 scanner and a compatible app, you can turn your phone into a powerful diagnostic tool.

Step 1: Download a Compatible App

Popular apps include:

  • Torque Pro (Android): Highly customizable, supports custom PIDs for Can-Am vehicles.
  • OBD Fusion (iOS/Android): User-friendly interface with real-time data logging.
  • BlueDriver App: Works seamlessly with BlueDriver scanners and includes repair insights.

Download the app from your device’s app store and create an account if required.

Step 2: Pair the Scanner with Your Phone

Turn on Bluetooth on your phone and scan for devices. Select your OBD2 scanner from the list and pair it. Enter the PIN if prompted (usually 1234 or 0000).

Step 3: Connect to the ATV and Run a Scan

Plug the scanner into the OBD2 port, turn the ignition on, and open the app. Tap “Connect” and wait for the app to establish a link with the ECU.

Once connected, tap “Read DTCs” to retrieve trouble codes. The app will display the codes, descriptions, and sometimes even suggested fixes.

Step 4: View Live Data (Optional)

Many apps allow you to view real-time sensor data, such as:

  • RPM
  • Coolant temperature
  • Throttle position
  • Oxygen sensor readings

This can help you spot irregularities before they trigger a code.
