Why This Matters / Understanding the Problem

You’re driving your Infiniti G35—smooth, stylish, and still turning heads in 2026—when suddenly, the Service Engine Soon light pops on. It’s not as urgent as the Check Engine light, but it’s still annoying and can distract you from enjoying your ride.

This light is your car’s way of saying, “Hey, it’s time for routine maintenance,” like an oil change, air filter swap, or spark plug check. But if you’ve already taken care of those services, the light may still be on, reminding you that the system hasn’t been reset.

Ignoring it won’t hurt your engine, but it will make it harder to spot real issues later. That’s why learning how to reset Service Engine Soon light on Infiniti G35 in 2026 is essential. It keeps your dashboard clean and your peace of mind intact.

Unlike older models, 2026 Infiniti G35s use updated onboard diagnostics (OBD-II) systems with smarter reminders. The reset process is simple—but only if you know the right steps. This guide walks you through it safely and correctly, so you avoid costly trips to the dealer.

What You Need

Good news: resetting the Service Engine Soon light doesn’t require a mechanic or fancy tools. Here’s what you’ll need:

• Your Infiniti G35 (2026 model) – parked safely, engine off, key fob nearby.
• Ignition key or key fob – to power the car without starting the engine.
• OBD2 scan tool (optional but recommended) – helps verify no active error codes before resetting.
• Owner’s manual – handy for dashboard layout and fuse box info.
• Pen and paper (or phone notes) – to record any codes if using a scanner.

Most drivers can reset the light using just the ignition method. But if you’ve had recent repairs or suspect a deeper issue, an OBD2 scanner adds peace of mind. We’ll cover both methods in the guide.

Note: If your car is under warranty, always check with your dealership before attempting a reset. Some service reminders are tied to warranty compliance, and skipping steps might void coverage.

Pro Tip: Always complete required maintenance before resetting the light. Resetting without fixing the issue is like silencing a smoke alarm while the fire still burns.

Step-by-Step Guide to How to Reset Service Engine Soon Light on Infiniti G35 in 2026

Step 1: Ensure Maintenance Is Up to Date

Before touching anything, confirm that your Infiniti G35 has had its scheduled service. The Service Engine Soon light usually appears every 5,000 to 7,500 miles, depending on driving conditions and oil type.

Check your owner’s manual for the exact maintenance schedule. For 2026 G35 models, this typically includes:

• Oil and filter change
• Tire rotation
• Air filter inspection/replacement
• Brake fluid and cabin filter check

If you skipped any of these, do them first. Resetting the light without completing maintenance can lead to long-term engine wear or voided warranties.

Once all maintenance is done, proceed to the next step. This is the only way to reset the Service Engine Soon light responsibly.

Step 2: Use an OBD2 Scanner to Check for Codes (Optional but Smart)

Even though the Service Engine Soon light is usually routine, it’s wise to scan for hidden codes. Sometimes, it’s triggered by minor sensor glitches or pending emissions issues.

Plug your OBD2 scanner into the port under the dashboard, just below the steering wheel. Turn the ignition to “ON” (don’t start the engine) and let the scanner power up.

Read any stored codes. If you see something like P0420 (catalyst efficiency) or P0171 (lean fuel mix), address those before resetting. Otherwise, you might reset the light only to have it return days later.

Clear any non-critical codes (if your scanner allows), or write them down for later review. If no codes appear, or they’re all “pending” and not active, you’re safe to reset.

Warning: Never reset active error codes without diagnosing them. Doing so can mask real problems and lead to expensive repairs down the road.

Step 3: Park and Prepare the Vehicle

Find a flat, safe spot—your driveway, garage, or parking lot. Turn off the engine and remove the key or press the power button to shut down the car.

Engage the parking brake. This isn’t just for safety; it ensures the car is in a stable state for the reset process. Open the driver’s side door and sit in the driver’s seat.

Make sure no accessories are on (radio, AC, lights). The car should be completely powered down. This helps the ECU (engine control unit) reset properly.

Double-check that your seatbelt is unbuckled—some Infiniti models use seatbelt sensors that can interfere with dashboard resets if triggered.

Step 4: Perform the Ignition Cycle Reset (The “Key Dance”)

This is the classic method for how to reset Service Engine Soon light on Infiniti G35 in 2026 without a scanner. It uses the car’s built-in reset protocol through the ignition system.

Follow these steps exactly:

1. Insert the key into the ignition (or have the fob in your pocket).
2. Turn the ignition to the “ON” position (dashboard lights up, engine off). Wait 3 seconds.
3. Turn the ignition to “OFF” and remove the key (or press power off). Wait 3 seconds.
4. Repeat this cycle—ON for 3 seconds, OFF for 3 seconds—exactly 3 times.
5. On the fourth turn, leave the ignition in the “ON” position.

After the fourth turn, the dashboard will flash briefly. The Service Engine Soon light may flicker, dim, or go out. This is normal.

Wait 30 seconds with the ignition in “ON.” During this time, the car’s computer is recalibrating the maintenance reminder system.

After 30 seconds, turn the ignition to “OFF” and remove the key. The reset process is now complete.

Pro Tip: Count out loud or use a timer. Rushing or skipping a cycle can cause the reset to fail. Patience pays off.

Step 5: Start the Engine and Verify the Reset

Now, start your Infiniti G35 normally. Turn the key or press the start button. Let the engine run for at least 30 seconds.

Watch the dashboard carefully. The Service Engine Soon light should not come back on. If it stays off, success! The reset worked.

If the light flashes or turns back on, it could mean:

• The reset cycle wasn’t followed precisely.
• There’s an unresolved maintenance issue.
• The ECU hasn’t fully reset (try the cycle again).

Try the ignition cycle once more. If the light still returns, use an OBD2 scanner to check for codes. There might be a deeper issue the system is trying to tell you about.

Step 6: Alternative Method – Using an OBD2 Scanner to Reset

If the ignition method doesn’t work, or you prefer a more direct approach, use an OBD2 scanner with reset functionality.

Plug in the scanner, turn the ignition to “ON,” and navigate to the “Maintenance Reset” or “Service Reminder” menu. Select “Reset Service Light” or similar option.

Follow the on-screen prompts. Most scanners will confirm the reset with a message like “Service Light Cleared.”

Turn off the ignition, unplug the scanner, and start the car. The light should remain off.

This method is especially useful if you’ve recently replaced the battery or had electrical work done—those events can sometimes reset the maintenance timer incorrectly.

Popular scanners for 2026 Infiniti models include the BlueDriver, Autel MaxiCOM, and Foxwell NT530. They’re user-friendly and support Infiniti-specific resets.

Step 7: Drive and Confirm Long-Term Success

Take your G35 for a 10–15 minute drive. This allows the ECU to run a full system check and confirm all sensors are communicating properly.

Accelerate gently, then coast. Make a few turns. Let the car warm up completely. The Service Engine Soon light should stay off.

After the drive, park and turn off the engine. Wait a few minutes, then restart. The light should still be off.

If it returns, don’t panic. It might take a few drive cycles (up to 50 miles) for the system to fully accept the reset. But if it comes back immediately, revisit the OBD2 scanner to check for codes.

This final step ensures your reset is permanent, not just a temporary fix.

Pro Tips & Common Mistakes to Avoid

Even simple resets can go wrong. Here are insider tips to make the process foolproof:

• Do the reset right after maintenance. Don’t wait weeks. The system expects the reset to happen within a short window after service.
• Use the correct ignition timing. Three seconds ON, three seconds OFF—no more, no less. Rushing causes failure.
• Don’t skip the OBD2 scan if you’re unsure. A $20 scanner can save you $200 in repairs by catching hidden codes.
• Check the battery voltage. A weak battery (below 12.4V) can interfere with ECU resets. Use a multimeter if needed.
• Keep your owner’s manual handy. 2026 Infiniti G35 models have slight variations based on trim (Sport, Luxe, etc.). The manual confirms the exact reset steps for your version.

Warning: Never use third-party apps that claim to reset service lights via Bluetooth without a scanner. Many are scams or malware. Stick to reputable OBD2 tools.

Common Mistakes:

• Starting the engine during the ignition cycle (it disrupts the reset).
• Forgetting to wait 30 seconds on the fourth ON cycle.
• Resetting without doing the actual maintenance (the light will return).
• Using a cheap, generic OBD2 tool that doesn’t support Infiniti-specific resets.
• Ignoring other dashboard warnings (like low tire pressure) while focusing on the service light.

One real-life example: A driver in Phoenix reset his G35’s light but ignored a pending P0455 code (evap leak). The light stayed off, but two weeks later, he failed emissions testing. A $15 scan could’ve caught it early.

FAQs About How to Reset Service Engine Soon Light on Infiniti G35 in 2026

Q: Can I reset the Service Engine Soon light without doing maintenance?

Technically, yes—but you shouldn’t. The light is a reminder for a reason. Skipping maintenance leads to poor fuel economy, reduced performance, and potential engine damage. Always complete the required service first.

This usually means the ECU detected an issue it can’t ignore. It could be a pending code, a sensor fault, or the system hasn’t fully recalibrated. Use an OBD2 scanner to check for codes. If none appear, try the reset again after a short drive.

Q: Is the reset process the same for all Infiniti G35 years?

No. The 2026 G35 uses a newer ECU and dashboard system. Older models (2003–2008) used different ignition cycles or required fuse removal. Always follow the steps for how to reset Service Engine Soon light on Infiniti G35 in 2026 specifically.

Q: Will resetting the light void my warranty?

No, resetting the service reminder won’t void your warranty. However, failing to perform required maintenance might. Keep records of oil changes, tire rotations, and other services. Dealers can check service history through your VIN.

Q: Can I use my phone to reset the light?

Only if you have a Bluetooth OBD2 scanner (like BlueDriver or FIXD) and a compatible app. The phone alone can’t reset the light. It acts as a display for the scanner. Never trust apps that claim to reset lights without hardware.

Q: What if I lost my key fob?

No problem. The ignition method works with a physical key. Just insert it into the ignition and follow the same ON/OFF cycle. The fob isn’t required for this reset.

Q: How often does the Service Engine Soon light come on?

Typically every 5,000 to 7,500 miles, depending on your driving habits and oil type. The 2026 G35 uses adaptive reminders—city driving (short trips, frequent stops) may trigger it sooner than highway driving.
