How to Reset Service Engine Soon Light Infiniti FX35 2026

Key Takeaways

• Locate the OBD2 port: Found under the dashboard near the steering wheel.
• Use an OBD2 scanner: Plug in and follow prompts to clear the light.
• Turn ignition to ON: Power up without starting the engine first.
• Check for error codes: Diagnose issues before resetting the warning light.
• Reset via scanner menu: Select “Erase” to turn off the light safely.
• Verify reset success: Ensure the light stays off after restarting the engine.

Why This Matters / Understanding the Problem

You’re driving your 2026 Infiniti FX35 and suddenly, the “Service Engine Soon” light pops up on your dashboard. It’s not flashing—so that’s good—but it’s still annoying, distracting, and maybe even stressing you out. You might wonder: Is this serious? Can I ignore it? How do I turn it off?

The Service Engine Soon light is different from the more urgent “Check Engine” light. While both relate to engine or emissions system issues, the Service Engine Soon indicator usually signals routine maintenance reminders or minor sensor triggers—like an oil change due or a loose gas cap. But even if it’s not an emergency, you don’t want to ignore it forever. That’s why learning how to reset Service Engine Soon light Infiniti FX35 2026 is essential for keeping your vehicle in top shape and avoiding unnecessary trips to the mechanic.

Unlike older models with manual reset buttons, the 2026 FX35 uses an integrated onboard diagnostic system (OBD-II) that tracks maintenance cycles and emissions performance. The light activates based on time, mileage, or specific sensor data. Resetting it isn’t just about turning off a warning—it’s about confirming that the required service has been completed and resetting the system’s memory.

Ignoring the light won’t break your car immediately, but it can mask real problems. For example, if the light came on due to a faulty oxygen sensor and you keep driving without addressing it, you could face poor fuel economy, increased emissions, or even catalytic converter damage down the line.

So, whether you just changed your oil, replaced a sensor, or want to clear a false trigger, knowing how to reset Service Engine Soon light Infiniti FX35 2026 gives you control, saves money, and keeps your SUV running smoothly. This guide walks you through every step—safely, clearly, and without jargon.

What You Need

Before we dive into the steps, let’s gather everything you’ll need. Don’t worry—this doesn’t require a full garage setup. Most tools are either built into your car or easily accessible.

• Your 2026 Infiniti FX35 – parked on a flat surface with the engine off and parking brake engaged
• Ignition key or key fob – needed to power the dashboard and access settings
• OBD-II scanner (optional but recommended) – a simple $20–$50 code reader from Amazon, AutoZone, or Walmart
• Smartphone or tablet (optional) – if using a Bluetooth OBD-II scanner with an app like Torque Pro or Car Scanner ELM OBD2
• Owner’s manual – helpful for confirming model-specific procedures or fuse locations
• Pen and paper (optional) – to note any error codes before resetting

Why an OBD-II scanner? While the FX35 allows a manual reset, using a scanner helps you diagnose the root cause of the light. For instance, if the code says P0457 (evaporative emissions leak), tightening the gas cap might fix it—no reset needed. Skipping diagnosis means you might reset the light only for it to return days later.

You don’t need mechanic-level skills. This process is designed for everyday drivers. But having the right tools ensures you do it right the first time. Think of it like using a flashlight when changing a lightbulb—you could do it in the dark, but why risk it?

Step-by-Step Guide to How to Reset Service Engine Soon Light Infiniti FX35 2026

There are two main methods to reset the Service Engine Soon light: the manual dashboard method and the OBD-II scanner method. We’ll cover both. The manual method works if the light is due to a scheduled maintenance reminder. The scanner method is better for diagnosing and clearing actual diagnostic trouble codes (DTCs).

Step 1: Park Safely and Prepare the Vehicle

Start by parking your 2026 Infiniti FX35 on a level surface—like your driveway or garage floor. Turn off the engine completely and engage the parking brake. Make sure all doors are closed.

Press the brake pedal once (without starting the engine) and press the Start/Stop button to turn the ignition to “ON” mode. You’ll see the dashboard lights up, but the engine won’t run. This powers the instrument cluster and infotainment system, which you’ll need for the reset.

Pro Tip: Avoid doing this while the car is running. Resetting systems while the engine is on can confuse the ECU and trigger false error codes. Always power up in “ignition ON, engine OFF” mode.

Step 2: Check for Diagnostic Trouble Codes (Use an OBD-II Scanner)

Before resetting anything, diagnose the cause. Plug your OBD-II scanner into the diagnostic port—it’s usually located under the dashboard, near the driver’s left knee, behind a small plastic cover labeled “OBD-II” or “DLC.”

Turn the ignition to “ON” again (engine off), then power on the scanner. Follow the device prompts to connect to your FX35. Most scanners will display a menu: select “Read Codes” or “DTC.”

You might see codes like:

• P0457 – Evaporative Emission System Leak (likely a loose gas cap)
• P0171 – System Too Lean (could be air filter or MAF sensor)
• P0440 – General EVAP Leak
• No codes – Could be a maintenance reminder (common after oil changes)

Write down any codes. If you see a code, fix the underlying issue first before resetting. For example:

• If it’s P0457, tighten the gas cap or replace it.
• If it’s a maintenance reminder (no DTC), proceed to reset.
• If you’re unsure, take a photo of the code and search online or ask a mechanic.

Using a scanner is the smartest way to reset Service Engine Soon light Infiniti FX35 2026 because it ensures you’re not ignoring a real problem.

Step 3: Clear Codes Using the OBD-II Scanner (Recommended Method)

Once you’ve confirmed the issue is resolved (or it’s a routine reminder), use the scanner to clear the codes.

On most OBD-II devices, go to the menu and select:

• “Clear Codes”
• “Erase DTCs”
• “Reset MIL” (Malfunction Indicator Lamp)

Confirm when prompted. The scanner will send a command to the ECU to clear all stored trouble codes and turn off the Service Engine Soon light.

Wait 10–15 seconds. Then, unplug the scanner and turn the ignition off. Wait another 30 seconds before turning it back on.

Now, start the engine. The light should be gone. If it stays off after a 5-minute drive, the reset was successful.

Warning: Never clear codes without understanding their cause. If the light returns within a few days, the problem wasn’t fixed—and you might face bigger repairs later.

Step 4: Manual Reset via Dashboard (No Scanner Option)

If you don’t have an OBD-II scanner, you can still reset the light using the dashboard controls. This method works best for maintenance reminder resets—like after an oil change or tire rotation.

Here’s how:

1. With the ignition in “ON” mode (engine off), press and hold the TRIP/RESET button on the instrument cluster.
2. While holding it, turn the ignition to “OFF” and then back to “ON” without releasing the button.
3. Keep holding the TRIP/RESET button for about 10 seconds. You’ll see the odometer flash or a message like “MAINTENANCE RESET” appear on the display.
4. Release the button. The Service Engine Soon light should blink and then go off.

Turn the ignition off, wait 30 seconds, then restart the car. The light should be gone.

Note: This method only resets maintenance reminders, not active diagnostic trouble codes. If your FX35 has a real fault (like a misfire or sensor failure), the light will return after a few drive cycles. Always verify with a scanner when possible.

Step 5: Drive Cycle Verification (Critical Final Step)

After resetting, your Infiniti’s computer needs to run a “drive cycle” to confirm everything is working. This is how the onboard diagnostics (OBD-II) system rechecks emissions and engine performance.

Here’s a simple drive cycle for the 2026 FX35:

• Start the engine and let it idle for 2–3 minutes (to warm up).
• Drive at 30–40 mph for 3–5 minutes (steady speed, no rapid acceleration).
• Accelerate to 50–55 mph and cruise for 2–3 minutes.
• Slow down to 20 mph without braking hard (let off the gas).
• Stop and idle for 1 minute.
• Repeat 2–3 times if the light doesn’t stay off.

Complete this within one day. If the Service Engine Soon light stays off after this drive, the reset was successful. If it comes back, there’s still an issue—likely a sensor, emissions problem, or incomplete repair.

Pro Tip: Avoid short trips (under 10 minutes) after resetting. The system needs time and varied driving conditions to complete self-tests.

Step 6: Use Infiniti InTouch App (Alternative Method for Tech-Savvy Owners)

The 2026 Infiniti FX35 comes with the Infiniti InTouch system, which includes a mobile app. While you can’t directly reset the Service Engine Soon light through the app, you can monitor vehicle health and receive maintenance alerts.

Here’s how to use it:

• Download the Infiniti InTouch Services app (iOS or Android).
• Log in with your Infiniti account.
• Pair your FX35 using the VIN or QR code on the infotainment screen.
• Check the “Vehicle Health” section. It may show “Maintenance Due” or “Check Engine.”
• After completing the reset, the app should update within 24 hours.

If the app still shows a warning after your reset, it might mean the onboard system hasn’t fully cleared. Try the drive cycle again or use an OBD-II scanner to double-check.

This method is great for tracking future maintenance and understanding why the light came on in the first place. Think of it as your digital mechanic sidekick.

Step 7: When to Visit a Dealership or Mechanic

Sometimes, the light won’t reset—even after following all steps. Here are signs you should visit a professional:

• The light returns within 1–2 days.
• You see multiple DTCs (e.g., P0300, P0101).
• The car runs rough, idles poorly, or has reduced power.
• You’ve tried both manual and scanner resets with no success.
• The scanner shows “pending codes” that won’t clear.

Dealerships have factory-level diagnostic tools (like Infiniti’s Consult III+) that can access deeper system data and perform forced resets. They can also update software if needed—something DIY tools can’t do.

Don’t panic. A visit to the dealer doesn’t always mean expensive repairs. Sometimes, it’s just a software glitch or a sensor that needs recalibration.

Pro Tips & Common Mistakes to Avoid

Resetting the Service Engine Soon light is simple—but a few mistakes can make it frustrating. Here’s what seasoned Infiniti owners wish they knew:

Pro Tip #1: Always check the gas cap first. A loose or damaged gas cap is the #1 cause of P0457 and similar codes. Tighten it firmly (three clicks), wait 10 minutes, then try the reset.

Pro Tip #2: Use a quality OBD-II scanner. Cheap $10 scanners may read codes but fail to clear them properly. Invest in a reliable brand like BlueDriver, Autel, or Innova.

Common Mistake #1: Resetting the light without fixing the problem. Example: You clear a P0171 code but never replace the clogged air filter. The light will return—and fuel efficiency will suffer.

Common Mistake #2: Skipping the drive cycle. The ECU needs real-world driving data to confirm repairs. Driving only 2 minutes around the block won’t cut it.

Common Mistake #3: Using the manual reset for active DTCs. The TRIP/RESET method only works for maintenance reminders. If the car has a real fault, the light will come back—usually within 50 miles.

Pro Tip #3: Reset the light after completing maintenance. If you reset it before changing the oil, the system won’t know the service was done. Always service first, then reset.

Pro Tip #4: Keep a log. Use your phone or a notebook to record when the light came on, what you did, and when it was reset. This helps track recurring issues and saves time during future diagnostics.

Also, remember: the Service Engine Soon light is not the same as the Check Engine Light. The latter is more urgent (often yellow or red), while the former is usually orange or amber. Don’t ignore either—but treat them differently.

Finally, if you’re selling your 2026 FX35, make sure the light is off and all maintenance is up to date. A clean service record increases resale value and shows the car has been well cared for.

FAQs About How to Reset Service Engine Soon Light Infiniti FX35 2026

Q1: Can I reset the Service Engine Soon light without a scanner?
Yes, you can use the manual dashboard method (holding the TRIP/RESET button). But this only works for maintenance reminders—not active diagnostic codes. For real issues, a scanner is strongly recommended.

Q2: Why does the light come back after I reset it?
The light returns because the underlying problem wasn’t fixed. For example, if you clear a P0440 code but don’t repair the EVAP system leak, the ECU will detect it again during the next drive cycle. Always diagnose first, then reset.

Q3: Is it safe to drive with the Service Engine Soon light on?
Generally, yes—but not long-term. The light often indicates a non-emergency issue (like a loose gas cap). However, if the car feels different (rough idle, loss of power, strange smells), stop driving and diagnose it immediately.

Q4: How much does it cost to reset the light at a mechanic?
Most shops charge $50–$100 for a diagnostic scan and reset. But if no repairs are needed, you can do it yourself for under $30 (cost of a basic scanner). Learning how to reset Service Engine Soon light Infiniti FX35 2026 saves you money in the long run.

Q5: Can I use my phone as an OBD-II scanner?
Yes! Pair a Bluetooth OBD-II adapter (like Veepeak or BAFX) with an app such as Torque Pro or Car Scanner ELM OBD2. These apps can read, clear codes, and even show real-time engine data. Just make sure your phone is compatible.

Q6: Will resetting the light affect my car’s performance?
No. Resetting only clears stored codes and turns off the warning light. It doesn’t change engine behavior. However, if you reset without fixing the issue, performance problems (like poor fuel economy) may continue.
