The B13 service code on your Honda’s dashboard might trigger confusion or even panic. 

In this guide, we’ll decipher the B13 code’s meaning, walk you through the essential maintenance it represents, and even explore how to “remove” it.


What Does The Honda B13 Service Code Mean?

Seeing the B13 code on your Honda’s dashboard signifies a time for crucial maintenance to keep your car running smoothly. Let’s decipher the code:

  • B: This stands for “Maintenance Interval B,” for replacing your engine oil and oil filter. Additionally, a visual inspection of various systems and components will be performed.
  • 1: This one’s simple – it means time for a tire rotation and a thorough check of their pressure and overall condition.
  • 3: The big one – the “3” indicates the need for a transmission fluid change. This ensures smooth gear changes and protects your transmission from wear and tear.

Ignoring the B13 code can lead to decreased performance, safety concerns, and even costly repairs down the line.

So, how to get rid of it? Simply complete the required maintenance! Once you’ve changed the oil, and filter, rotated the tires, and replaced the transmission fluid, reset the maintenance minder system (we’ll tell you how).

What Is The Recommended Mileage For A Honda B13 Service?

Forget the old “oil change every 3,000 miles” routine! Your Honda B13 service throws out the mileage rulebook and relies on a smarter system: the maintenance minder.

Instead of a fixed mileage interval, the B13 code pops up on your dashboard when various sensors within your car determine specific components that need attention. 

This personalized approach ensures your Honda receives the right care at the right time, optimizing performance, fuel efficiency, and longevity.

So, what triggers the B13 code? It’s a three-part message, as mentioned before:

  • Engine oil and filter change
  • Tire rotation and inspection
  • Transmission fluid replacement

How Often Should You Conduct The Honda B13 Service?

Traditional “every X miles” servicing is like a one-size-fits-all suit on your car. Sure, it might cover the basics, but it ignores how YOU drive and the unique demands you put on your engine. The B13 code, on the other hand, is like a personalized sign from your Honda, telling you exactly what it needs right now.

But here’s the kicker: even though the B13 code is a great starting point, it’s not the whole story. 

That’s why we recommend going beyond the B13 code and adopting a proactive maintenance mindset. We suggest every 10,000 miles, treat it to fresh air filters, spark plugs, and maybe even a fuel injector cleaning.

Trust us, your wallet will thank you later, and you’ll avoid those dealership “surprises” that leave you feeling frustrated.


How to Remove Honda B13?

Here’s your step-by-step guide to resetting the light, tailored for 2007 and newer Honda models:

Step 1: Turn on the Engine (But Don’t Start It!)

Twist the key to the “on” position, right before the engine sputters to life. This awakens the car’s electrical system, preparing it for your commands.

Step 2: Seek Out the Select/Reset Button

This button is your key to silencing the B13. Depending on your model, it might be a knob on the dashboard or a button on the steering wheel. It’s usually well-marked, so you won’t be hunting for hours.

Step 3: Navigate the Digital Landscape

Use the Select/Reset button, scrolling through various options on your display. Find the “Engine Oil Life” or “Engine Oil Indicator %” message. 

Step 4: Hold the Key

Once you’ve found the oil life message, press and hold the Select/Reset button for a full 10 seconds. This is like holding the password to unlock the secret oil light reset chamber. The Engine Oil Indicator will start blinking.

Step 5: Choose Your Reset Path

Depending on your display, you’ll have two options:

  • Engine Oil Life: If you see this message, press the Info button on your steering wheel to enter Reset mode. Then, press the Select/Reset button again, and voila! Your oil life will reset to 100%.
  • Engine Oil Indicator %: If this is your display, simply hold the Select/Reset button for more than 5 seconds. The oil life indicator % will jump to 100%.

Congratulations! You’ve successfully reset your oil light and appeased the B13 code. Remember, regular oil changes are crucial for your car’s health.

Note: The B13 code will reappear when the next maintenance interval is due.

Step 0 – Assess Your Skills and Tools

  • Comfort Level: Are you confident performing basic car maintenance tasks like oil changes and filter replacements?
  • Tooling Up: Do you have essential tools like jack stands, wrenches, oil drain pan, and filters for your specific Honda model?
  • Safety First: Knowledge of safe handling of used oil and fluids is crucial. Ensure proper disposal methods in your area.

Step 1: Gather Your Supplies

  • Engine oil and filter
  • Transmission fluid
  • Air filters (engine and cabin)
  • Tire rotation tools (optional)
  • Safety gear

Step 2: Oil Change and Filter

  • Warm up the engine for a few minutes.
  • Locate the oil drain plug and filter housing. Place the oil pan underneath.
  • Unscrew the drain plug and let the oil drain completely. Be mindful of hot oil!
  • Once drained, replace the drain plug with a new washer and tighten it securely.
  • Remove the old oil filter using a filter wrench and replace it with a new one, tightening hand-tight first.
  • Fill the engine with fresh oil according to the manual’s recommended capacity. Use a funnel to avoid spills.
  • Check the oil level dipstick and ensure it’s within the safe range.

Step 3: Transmission Fluid Change

  • WARNING: This step requires more technical knowledge and specific tools depending on your Honda model. Consult your manual or online tutorials for detailed instructions. Incorrect procedures can damage your transmission.
  • If confident, follow your manual’s guide for draining and refilling the transmission fluid. Remember, specific fluid types and quantities are crucial.

Step 4: Air Filter Replacements

  • Locate the engine air filter housing and cabin air filter compartment (usually behind the glove box).
  • Consult your manual for specific removal and installation instructions.
  • Replace both filters with new ones, ensuring proper fit and seal.

Step 5: Tire Rotation (Optional)

  • Consult your manual for your Honda’s recommended tire rotation pattern.
  • Jack up the vehicle securely using jack stands, following proper safety protocols.
  • Loosen the lug nuts on each wheel before lifting it completely.
  • Rotate the tires according to the recommended pattern and tighten the lug nuts securely with a torque wrench.

Step 6: Waste Disposal

Dispose of used oil and filters responsibly at designated recycling centers. Do not pour them down drains or dump them in the trash.

DIYing the B13 service can be rewarding, but be honest about your skills and comfort level. If unsure, don’t hesitate to seek help from a qualified mechanic.


How Long Does A Honda B13 Service Take?

The B13 service might sound complex, but its duration depends on several factors:

Factor #1 – Service Provider

  • Dealerships: While offering convenience and expertise, dealerships often have longer wait times due to appointment schedules and workload. Expect 2-3 hours.
  • Independent Mechanics: Often quicker due to smaller client bases, but efficiency can vary. Aim for 1.5-2.5 hours.
  • DIY: The time is entirely in your hands! Be realistic based on your skill level, tools, and any unforeseen challenges. Budget 2-4 hours, including potential troubleshooting.

Factor #2 – Service Complexity

This includes oil change, filter replacements, tire rotation, and inspection. Expect the shorter end of the timeframes mentioned above.

If you request fluid changes beyond engine oil (e.g., brake fluid), expect extra time. Complex repairs might require additional days depending on the issue.

Factor #3 – Vehicle Condition

If your car is well-maintained and everything runs smoothly, the service should be quicker. However, rusted bolts, worn parts, or hidden problems can extend the service duration.


Final Word

Now that you’ve conquered the B13 code, remember, it’s just one piece of the puzzle in ensuring your Honda’s long-term health. Regular maintenance goes beyond addressing service codes; it’s about proactive care.
