Seeing the B1 maintenance code on your Honda Accord’s dashboard can be confusing if you’re not familiar with Honda’s Maintenance Minder system. This comprehensive guide explains exactly what the B1 code means, what services are required, and your options for addressing it—whether you prefer professional service or a DIY approach. Understanding this code is essential for keeping your Accord running smoothly and maintaining its longevity.
What Does the B1 Maintenance Code Mean?
The Honda Maintenance Minder system uses a combination of letters and numbers to indicate specific maintenance needs. When you see the B1 code on your Honda Accord’s dashboard, it’s telling you two specific services are due:
The “B” Service Component
The letter “B” indicates your vehicle needs:
- Engine oil and oil filter change
- Comprehensive mechanical inspection
- Inspection of brake pads, calipers, and rotors
- Inspection of all fluid levels and condition
- Inspection of suspension components
- Inspection of the exhaust system
The “1” Service Component
The number “1” specifically indicates:
- Tire rotation
- Tire pressure adjustment
- Tire wear inspection
Together, the B1 service ensures your Honda Accord’s engine continues to operate efficiently while maintaining even tire wear for optimal handling and safety.
Why These Services Are Grouped Together
Honda’s Maintenance Minder system is designed to optimize service intervals based on your actual driving habits rather than arbitrary mileage points. The B1 service combination makes logical sense for several reasons:
The B1 service typically occurs every 5,000 to 7,500 miles or approximately every six months, depending on your driving conditions and habits.
- Complementary timing: Oil changes and tire rotations have similar recommended intervals
- Efficiency: Combining these services saves you time and potentially money
- Preventative maintenance: The inspection components help catch potential issues before they become serious problems
- Optimal performance: Fresh oil and properly rotated tires both contribute to fuel efficiency and vehicle longevity
Step-by-Step: The Oil Change Process
Whether you’re taking your Honda Accord to a professional or performing the oil change yourself, here’s what the process entails:
- Prepare the vehicle: Ensure the engine is warm but not hot, and park on a level surface
- Gather supplies: You’ll need the correct oil, a new oil filter, a drain pan, and basic tools
- Locate and remove the oil drain plug: Position the drain pan underneath and carefully remove the plug
- Allow oil to drain completely: This typically takes 5-10 minutes
- Replace the oil filter: Remove the old filter and install a new one, ensuring the gasket is properly seated
- Replace the drain plug: Install with a new washer if needed and tighten to proper specifications (30 ft-lbs for most Honda models)
- Add new oil: Pour in the recommended amount of oil through the oil fill cap
- Check oil level: Start the engine briefly, then check the dipstick to ensure proper oil level
Recommended Oil Type for Honda Accord
| Accord Model Year | Recommended Oil Type | Oil Capacity |
| 2018-2024 | 0W-20 Full Synthetic | 4.4 quarts (with filter) |
| 2013-2017 | 0W-20 Full Synthetic | 4.2 quarts (with filter) |
| 2008-2012 | 5W-20 Synthetic Blend | 4.5 quarts (with filter) |
Important: Always use Honda-approved oil filters for optimal performance and longevity. Using incorrect or low-quality filters can lead to engine damage and may void your warranty.

Tire Rotation Patterns for Honda Accord
Proper tire rotation is crucial for even tire wear and maximum tire life. The correct rotation pattern depends on your Honda Accord’s drivetrain:
Front-Wheel Drive Accords
Most Honda Accords are front-wheel drive and should follow the “forward cross” pattern:
- Front tires move straight back to the rear
- Rear tires move to the opposite side at the front
All-Wheel Drive Accords
For AWD Accord models, use the “X-pattern” rotation:
- Each tire moves diagonally to the opposite corner
- This ensures even wear across all four tires
Tire Rotation Process
- Loosen lug nuts: While the vehicle is still on the ground, loosen (but don’t remove) all lug nuts
- Raise the vehicle: Use a jack and secure with jack stands
- Remove wheels: Take off all wheels and arrange them according to the correct pattern
- Inspect tires: Check for uneven wear, damage, or embedded objects
- Reinstall wheels: Place each tire in its new position
- Tighten lug nuts: Hand-tighten first, then lower the vehicle and torque to specification (usually 80-85 ft-lbs for Honda Accord)
- Check tire pressure: Adjust all tires to the recommended PSI (found on the driver’s door jamb sticker)

Consequences of Ignoring the B1 Maintenance Reminder
Postponing or ignoring the B1 service can lead to several issues that may affect your Honda Accord’s performance, safety, and longevity:
Short-Term Consequences
- Reduced fuel efficiency: Dirty oil can increase engine friction and reduce MPG
- Uneven tire wear: Skipping rotation leads to premature tire replacement
- Decreased performance: Engine may not run as smoothly or responsively
- Persistent warning light: Maintenance Minder will continue to remind you
Long-Term Consequences
- Engine damage: Degraded oil loses its protective properties
- Expensive repairs: Minor issues can develop into major problems
- Reduced vehicle lifespan: Consistent maintenance neglect shortens vehicle life
- Lower resale value: Incomplete maintenance history affects value
Warning: Consistently ignoring maintenance reminders may void portions of your Honda warranty. Most warranties require proof of regular maintenance according to the manufacturer’s schedule.
How to Reset the Maintenance Minder After Service
After completing the B1 service, you’ll need to reset the Maintenance Minder system. The process varies slightly depending on your Honda Accord’s model year:

- Use the steering wheel controls to navigate to “Vehicle Settings”
- Select “Maintenance Info”
- Choose “Reset Maintenance Code(s)”
- Select “B1” from the list
- Confirm by selecting “Yes”
For 2013-2017 Accord Models
- Turn the ignition to ON (don’t start the engine)

Frequently Asked Questions About Honda B1 Service
How urgent is the B1 service when it appears?
While not an emergency, the B1 service should be addressed within 500 miles of appearing. The Maintenance Minder system is designed to give you advance notice before maintenance becomes critical. Prolonged delay beyond this window may impact vehicle performance and potentially lead to accelerated wear.
Can I perform just part of the B1 service?
It’s not recommended to split the B1 service. The oil change and tire rotation are designed to be performed together for optimal maintenance timing. If you only complete part of the service, the Maintenance Minder system won’t accurately track your maintenance needs, potentially leading to maintenance gaps.
Does using synthetic oil extend the interval between B1 services?
Modern Honda Accords are designed to use full synthetic oil, and the Maintenance Minder system already accounts for this in its calculations. While synthetic oil generally lasts longer than conventional oil, you should still follow the Maintenance Minder’s recommendations rather than extending intervals beyond what the system indicates.
Will aftermarket parts affect my Honda warranty?
Using aftermarket parts for maintenance generally won’t void your warranty unless Honda can prove that the aftermarket part caused a specific failure. However, using Honda Genuine parts provides assurance of proper fit and function. For vehicles under warranty, keeping detailed maintenance records is important regardless of where service is performed.
