Why Does the Check Engine Light Come On?

Before we dive into resetting the light, it’s important to understand why it’s on in the first place. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your Can-Am Outlander’s onboard diagnostic system. It monitors everything from engine performance and emissions to fuel delivery and electrical systems.

When a sensor detects an anomaly—like a drop in fuel pressure, a misfire, or a faulty oxygen sensor—the engine control unit (ECU) logs a trouble code and triggers the light. This is your ATV’s way of alerting you to a potential issue that could affect performance, fuel efficiency, or even safety.

Common Causes of the Check Engine Light on a Can-Am Outlander

• Loose or damaged gas cap: A simple but often overlooked cause. If the cap isn’t sealed properly, fuel vapors can escape, triggering an emissions-related code.
• Faulty oxygen (O2) sensor: This sensor monitors exhaust gases and helps regulate the air-fuel mixture. A failing O2 sensor can reduce fuel economy and increase emissions.
• Spark plug or ignition coil issues: Worn spark plugs or failing coils can cause misfires, leading to rough idling and poor acceleration.
• Clogged air filter: A dirty air filter restricts airflow, causing the engine to run rich (too much fuel), which can trigger a code.
• Throttle position sensor (TPS) problems: If the TPS sends incorrect data to the ECU, it can cause erratic throttle response and trigger the light.
• Fuel system issues: Problems with the fuel pump, injectors, or pressure regulator can lead to poor engine performance and warning lights.
• Electrical faults: Corroded connectors, damaged wiring, or a weak battery can disrupt sensor signals and cause false alarms.

Understanding these common causes helps you diagnose the problem before resetting the light. Never reset the check engine light without addressing the root issue—otherwise, it will likely come back on, and you could risk further damage.

Tools You’ll Need

Depending on the method you choose, you may need a few tools. Here’s a quick checklist to get started:

• OBD2 scanner (recommended): A handheld diagnostic tool that plugs into your Outlander’s OBD2 port. Look for one compatible with Can-Am or BRP vehicles (e.g., Foxwell NT510, Autel MaxiCOM).
• Owner’s manual: Your Outlander’s manual contains model-specific instructions and menu navigation tips.
• Basic hand tools: Screwdrivers, wrenches, or socket sets (for accessing the battery or gas cap).
• Clean cloth and contact cleaner: Useful for cleaning connectors or sensors.
• Multimeter (optional): Helps test electrical components like sensors or fuses.

While some methods require minimal tools, investing in an OBD2 scanner is highly recommended. It gives you accurate diagnostic information and ensures a proper reset.

Method 1: Using an OBD2 Scanner (Best Practice)

The most reliable and professional way to reset the check engine light on your Can-Am Outlander is by using an OBD2 scanner. This method not only clears the light but also reads and clears diagnostic trouble codes (DTCs), giving you insight into what caused the issue in the first place.

Step 1: Locate the OBD2 Port

The OBD2 port on most Can-Am Outlander models is located under the driver’s side of the dashboard, near the footwell. It’s a 16-pin connector, usually black or gray, and may be covered by a small plastic flap. If you can’t find it, consult your owner’s manual—port locations can vary slightly by model year.

Step 2: Turn Off the Ignition

Before connecting the scanner, make sure the ignition is turned off. This prevents any electrical surges or communication errors during the connection process.

Step 3: Plug in the OBD2 Scanner

Insert the scanner’s connector into the OBD2 port firmly. Ensure it’s fully seated to avoid loose connections. Most scanners will power on automatically once plugged in.

Step 4: Turn the Ignition to “On” (Do Not Start the Engine)

Turn the key to the “ON” position (also called “key-on, engine-off” or KOEO). This powers up the ECU and allows the scanner to communicate with the vehicle’s computer. Do not start the engine unless instructed by the scanner.

Step 5: Read the Trouble Codes

Follow the scanner’s on-screen prompts to read the stored trouble codes. These codes—like P0300 (random misfire) or P0171 (system too lean)—help identify the specific issue. Write them down or take a photo for reference.

Some advanced scanners also provide code definitions, possible causes, and even repair suggestions. This information is invaluable for diagnosing the problem.

Step 6: Fix the Underlying Issue

Before resetting the light, address the cause of the code. For example:

• If the code is P0455 (large evaporative leak), check and tighten the gas cap.
• If it’s P0133 (O2 sensor slow response), inspect the sensor for damage or corrosion.
• If it’s P0301 (cylinder 1 misfire), check the spark plug and ignition coil.

Once the issue is resolved, proceed to the next step.

Step 7: Clear the Codes and Reset the Light

On your scanner, select the option to “Clear Codes” or “Erase DTCs.” The scanner will send a command to the ECU to delete the stored trouble codes and turn off the check engine light.

After clearing, the scanner may prompt you to turn the ignition off and back on. Follow the instructions carefully.

Step 8: Verify the Reset

Turn the ignition back on and check the dashboard. The check engine light should be off. If it remains on, the issue may not be fully resolved, or a new code may have been triggered.

Take your Outlander for a short test ride (10–15 miles) to ensure the light doesn’t return. The ECU may need to complete a drive cycle to confirm the fix.

Pro Tip: Keep a log of all trouble codes and repairs. This helps track recurring issues and can be useful for warranty claims or resale.

Method 2: Disconnecting the Battery (Temporary Fix)

If you don’t have an OBD2 scanner, 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 may not clear all codes.

Step 1: Turn Off the Ignition and Remove the Key

Ensure the ATV is completely off. Remove the key to prevent accidental starts.

Step 2: Locate the Battery

The battery on most Can-Am Outlander models is located under the seat. Lift the seat using the latch or bolt, then remove any covers or brackets securing the battery.

Step 3: Disconnect the Negative Terminal First

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

Safety Note: Always disconnect the negative terminal first to avoid short circuits. Reconnect it last when reassembling.

Step 4: Wait 10–15 Minutes

Leave the battery disconnected for at least 10 to 15 minutes. This allows the ECU’s capacitors to discharge and reset the system. Some sources recommend up to 30 minutes for a full reset.

Step 5: Reconnect the Battery

Reattach the negative terminal and tighten the nut securely. Then reconnect the positive (+) terminal. Ensure both connections are clean and tight.

Step 6: Reinstall the Seat and Covers

Replace any covers or brackets and secure the seat back in place.

Step 7: Turn On the Ignition

Turn the key to the “ON” position and check the dashboard. The check engine light should be off—at least temporarily.

Start the engine and let it idle for a few minutes. Take a short test ride to see if the light returns.

Important: This method may clear the light, but if the underlying issue isn’t fixed, the light will likely come back on after a few drive cycles. It’s a temporary solution, not a permanent fix.

Method 3: Using the Instrument Cluster (If Available)

Some newer Can-Am Outlander models (typically 2017 and later) feature advanced instrument clusters with menu systems that allow you to reset certain warnings—including the check engine light—without tools.

Step 1: Turn the Ignition to “On”

Turn the key to the “ON” position without starting the engine. This powers up the display.

Step 2: Navigate the Menu

Use the buttons on the handlebar or dashboard to access the menu. Look for options like “Settings,” “Diagnostics,” or “Reset.”

Step 3: Find the Reset Option

Scroll through the menu to find a reset or clear function. Some models may have a “Clear MIL” (Malfunction Indicator Lamp) option.

Step 4: Confirm the Reset

Select the option and confirm when prompted. The system will clear the stored codes and turn off the check engine light.

Note: Not all Outlander models support this feature. Check your owner’s manual or contact a Can-Am dealer to confirm compatibility.

Troubleshooting: What If the Light Comes Back On?

Even after resetting the check engine light, it may return—sometimes within minutes. This usually means the problem wasn’t fully resolved. Here’s how to troubleshoot:

1. Recheck the Gas Cap

A loose, cracked, or missing gas cap is one of the most common causes. Remove it, inspect for damage, and reinstall it securely. Tighten until you hear a click.

2. Inspect Sensors and Connections

Check the O2 sensor, throttle position sensor, and crankshaft position sensor for dirt, corrosion, or loose wires. Clean connectors with electrical contact cleaner and reseat them.

3. Test the Battery and Charging System

A weak battery or faulty alternator can cause electrical gremlins. Use a multimeter to check voltage (should be 12.6V off, 13.5–14.5V running). Replace if below 12.4V.

4. Look for Vacuum Leaks

Inspect hoses and intake manifolds for cracks or disconnections. A vacuum leak can cause lean codes and rough running.

5. Monitor Driving Conditions

Sometimes, the ECU needs a complete drive cycle to verify repairs. Drive under varied conditions—idling, accelerating, cruising, and decelerating—for 20–30 minutes.

If the light persists after these steps, it’s time to consult a professional. A certified Can-Am technician can perform advanced diagnostics and ensure your Outlander is in top condition.

Preventing Future Check Engine Lights

An ounce of prevention is worth a pound of cure. Here are some tips to keep your Outlander running smoothly and avoid unnecessary warning lights:

• Perform regular maintenance: Follow the service schedule in your owner’s manual—oil changes, air filter replacements, and spark plug checks.
• Use quality fuel and oil: Stick to recommended fuel octane and synthetic oil to protect the engine and emissions system.
• Inspect after off-roading: Mud, water, and debris can damage sensors and wiring. Clean your ATV thoroughly after tough rides.
• Tighten the gas cap after every fill-up: Make it a habit to check the cap before heading out.
• Store properly: Use a battery tender during long storage periods to prevent drain and ECU issues.
