Before you reset the light, it’s important to understand what it means. The check engine light—also known as the Malfunction Indicator Lamp (MIL)—is part of your Spark’s onboard diagnostic system. When the engine control unit (ECU) detects a problem with the engine, fuel system, emissions, or sensors, it triggers the light to alert you.
Common reasons the light may come on include:
– A loose or faulty fuel cap
– A malfunctioning oxygen sensor
– Water intrusion in electrical components
– Low engine oil level
– Faulty spark plugs or ignition system
– Issues with the fuel injector
– Sensor failures (like throttle position or crankshaft sensors)
The Seadoo Spark uses a digital multifunction display (MFD) to show error codes and system status. Unlike cars, it doesn’t have a standard OBD2 port, so you can’t just plug in any generic scanner. Instead, it relies on BRP’s proprietary communication system.
That said, you can still read and clear many codes using the display itself or a compatible diagnostic tool. But again—resetting the light without fixing the problem is like silencing a fire alarm while the house is still burning. Always diagnose first.
Method 1: Using the Onboard Diagnostic Mode (No Tools Required)
The easiest and most accessible way to reset the check engine light on your Seadoo Spark is by using the built-in diagnostic mode. This method doesn’t require any special tools—just your hands and a few minutes of your time.
This process works on most Seadoo Spark models, including the 2up, 3up, and various engine sizes (900 ACE, 900 HO, etc.). It allows you to read active error codes and clear them directly from the multifunction display.
Step 1: Turn Off the Engine and Remove the Key
Start by making sure your Spark is completely powered down. Turn off the engine and remove the safety lanyard (key) from the ignition. This ensures no power is flowing to the ECU during the reset process.
Wait about 30 seconds to allow the system to fully power down. This gives the ECU time to reset its memory.
Step 2: Reinsert the Key and Turn to “ON” (Do Not Start)
Reinsert the safety lanyard and turn the ignition switch 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.
At this point, the display will show the normal startup screen. Wait for it to fully load.
Step 3: Access the Diagnostic Menu
Now, you’ll need to enter the diagnostic mode. Here’s how:
– Press and hold the “MODE” button on the right handlebar control.
– While holding MODE, press and release the “SET” button three times within five seconds.
– Release the MODE button.
If done correctly, the display will switch to a diagnostic screen showing “DIAG” or “DIAGNOSTIC MODE.”
Step 4: Read the Error Codes
Once in diagnostic mode, use the “MODE” and “SET” buttons to navigate through the menu. Look for a section labeled “FAULTS” or “ERROR CODES.”
The display will show any active or stored error codes. These codes are usually two or three digits, like “E12” or “P0171.” Write them down—you’ll need them to understand what’s wrong.
For example:
– E12: Low engine oil pressure
– E14: Water in fuel sensor fault
– E20: Throttle position sensor issue
Refer to your owner’s manual or BRP’s official code list for full explanations.
Step 5: Clear the Codes
After reviewing the codes, you can clear them:
– Navigate to the “CLEAR FAULTS” or “RESET” option.
– Press and hold the “SET” button for 3–5 seconds until the screen confirms the reset.
– Exit diagnostic mode by turning the ignition off and removing the key.
Step 6: Test the System
Reinsert the key, turn the ignition to “ON,” and check if the check engine light is off. Then, start the engine and let it idle for a few minutes. Take it for a short test ride to ensure everything runs smoothly.
If the light stays off, great! The issue may have been temporary. But if it comes back on, the problem is still present and needs further attention.
Method 2: Battery Disconnect Reset (Simple but Limited)
If the onboard method doesn’t work or you can’t access the diagnostic menu, a battery disconnect can sometimes reset the ECU and clear the check engine light. This method works by cutting power to the engine control unit, forcing it to reboot.
However, this is a temporary fix and may not clear all codes—especially persistent or hard faults. It’s best used as a quick troubleshooting step.
Step 1: Turn Off the Engine and Remove the Key
As always, start by shutting down the Spark completely. Remove the safety lanyard and ensure the engine is off.
Step 2: Locate the Battery
On the Seadoo Spark, the battery is located under the rear seat. Lift the seat using the latch or release lever. You’ll see the battery compartment—usually a small, sealed AGM (absorbent glass mat) battery.
Step 3: Disconnect the Negative Terminal
Using a 10mm wrench or socket, loosen the nut on the negative (black) battery terminal. Carefully remove the cable and tuck it away from the battery so it doesn’t accidentally touch the terminal.
Wait at least 10–15 minutes. This gives the ECU time to fully discharge and reset its memory.
Step 4: Reconnect the Battery
After waiting, reconnect the negative terminal and tighten the nut securely. Make sure the connection is snug to avoid electrical issues.
Replace the seat and ensure it’s locked in place.
Step 5: Power On and Test
Reinsert the key and turn the ignition to “ON.” Check if the check engine light is off. Start the engine and let it run for a few minutes.
Take a short test ride to see if the light returns. If it does, the underlying issue hasn’t been resolved.
Method 3: Using a BRP Diagnostic Scanner (Most Effective)
For the most accurate and reliable way to reset the check engine light on your Seadoo Spark, a BRP-approved diagnostic tool is the best option. These scanners connect directly to the Spark’s communication port and provide detailed information about engine performance, sensor readings, and fault codes.
The most common tool is the BRP Can-Am Diagnostic Scanner (also used for Seadoos). It’s available through authorized BRP dealers or online retailers.
Step 1: Purchase or Borrow a Compatible Scanner
You’ll need a scanner that’s compatible with Seadoo Spark models. The BRP Can-Am Diagnostic Tool (part number 529000654) is the official choice. Some third-party tools may work, but they may not support all functions.
Step 2: Locate the Diagnostic Port
On the Seadoo Spark, the diagnostic port is typically located under the handlebars or near the steering column. It’s a small, rectangular connector with multiple pins.
You may need to remove a small cover or panel to access it.
Step 3: Connect the Scanner
Plug the diagnostic scanner into the port. Turn the ignition to “ON” (do not start the engine). The scanner should power up and establish communication with the ECU.
Step 4: Read and Clear Codes
Use the scanner’s interface to:
– Read active and stored fault codes
– View real-time sensor data (like engine temp, RPM, throttle position)
– Clear error codes
– Perform system tests
Follow the on-screen prompts to clear the check engine light. The scanner will confirm when the reset is complete.
Step 5: Disconnect and Test
Once the codes are cleared, disconnect the scanner. Turn the ignition off and back on. Start the engine and take a test ride.
This method is the most thorough and is recommended if the light keeps returning or if you suspect a serious issue.
Common Causes of the Check Engine Light on Seadoo Spark
Understanding why the light came on in the first place can help you prevent future issues. Here are some of the most common causes:
Loose or Faulty Fuel Cap
A loose, damaged, or missing fuel cap can trigger the check engine light. The cap maintains pressure in the fuel system, and if it’s not sealed properly, the ECU detects a vapor leak.
Solution: Tighten the cap securely. If it’s cracked or worn, replace it with a genuine BRP part.
Water Intrusion
The Seadoo Spark is water-resistant, not waterproof. If water gets into electrical connectors, sensors, or the ECU, it can cause short circuits and trigger error codes.
Solution: Inspect connectors for corrosion or moisture. Dry them thoroughly and apply dielectric grease to prevent future issues.
Faulty Oxygen Sensor
The O2 sensor monitors exhaust gases and helps the ECU adjust the air-fuel mixture. If it fails, it can cause poor performance and trigger the light.
Solution: Use a diagnostic tool to check sensor readings. Replace if faulty.
Low Engine Oil
The Spark has an oil level sensor. If oil is low, the ECU will trigger a warning to prevent engine damage.
Solution: Check the oil level using the dipstick or electronic sensor. Top off with the recommended oil (BRP XPS 2-Stroke Oil).
Spark Plug Issues
Worn or fouled spark plugs can cause misfires, poor acceleration, and trigger the check engine light.
Solution: Inspect and replace spark plugs every 50–100 hours of operation or as recommended.
Throttle Position Sensor (TPS) Malfunction
The TPS tells the ECU how far the throttle is open. If it’s out of calibration or damaged, the engine may run rough or stall.
Solution: Use a scanner to check TPS readings. Recalibrate or replace if necessary.
Troubleshooting Persistent Check Engine Lights
If the check engine light keeps coming back after a reset, it’s a sign of a deeper issue. Here’s how to troubleshoot:
Check for Recurring Codes
Use the onboard diagnostic mode or a scanner to see if the same code returns. Recurring codes indicate a persistent fault.
Inspect Electrical Connections
Loose, corroded, or damaged connectors are common culprits. Check all sensors, the ECU, and the battery terminals.
Test Sensor Outputs
Use a multimeter or scanner to test sensor voltages. Compare readings to specifications in the service manual.
Look for Mechanical Issues
Listen for unusual noises, check for leaks, and inspect the exhaust system. Mechanical problems can trigger electronic warnings.
Consult a BRP Dealer
If you can’t identify or fix the issue, take your Spark to an authorized BRP dealer. They have advanced tools and expertise to diagnose complex problems.
