About this guide: Honda Libertyville is an authorized Honda dealer at 1111 S Milwaukee Ave. Our factory-certified technicians service Honda vehicles using Honda maintenance specifications and service procedures. Last reviewed August 2026.
When your Honda's dashboard shows an A, a B, or a combination such as B123, it is telling you which maintenance items are due. Honda's Maintenance Minder does not rely on one universal mileage interval for every driver. Instead, it uses vehicle operating conditions and calculated oil life to determine when maintenance should be performed.
Under Honda's Maintenance Minder definitions, an A main item means replace engine oil. A B main item means replace engine oil and oil filter and perform Honda-specified inspections. Numbered maintenance items can then appear alongside A or B for services such as tire rotation, filter and drive-belt service, transmission fluid, spark plugs, coolant, brake fluid, and other model-specific maintenance.
Exact maintenance-item definitions can vary by model and model year, and current Honda vehicles may use additional numbered items beyond the codes found on older models. Always confirm the code against the owner's manual for your specific Honda.
This guide explains what's included in an A visit versus a B visit, how common numbered items stack on top of the main service, what changes across Honda models including Civic, Accord, CR-V, HR-V, Pilot, Passport, Ridgeline, Odyssey, and Prologue, and how Lake County driving conditions can affect maintenance needs. If you landed here because a specific code just appeared, our Maintenance Minder Codes guide provides a more detailed code breakdown.
Why Honda Doesn't Use One Fixed Mileage Chart
Some maintenance schedules are presented as simple mileage milestones - service at 10,000 miles, again at 20,000 miles, and so on. Honda's Maintenance Minder works differently on equipped vehicles. It calculates remaining engine-oil life using vehicle operating conditions and displays maintenance information when service is approaching.
That means two otherwise similar Hondas can display maintenance reminders at different odometer readings. A printed "Honda maintenance schedule" with one exact mileage for every driver and every model does not fully reflect how Maintenance Minder works.
The best reference is the Maintenance Minder display together with the owner's manual for your exact model and model year. This guide focuses on what the common A, B, and numbered maintenance items mean and what you can expect when they appear.
What's Included in an A Service
Honda defines the base A Maintenance Minder item as replacement of the engine oil. The correct oil specification depends on your Honda's model, model year, and powertrain, so service should follow the requirements listed in the applicable owner's manual.
Numbered maintenance items may then appear alongside A:
| Code | What's Included |
|---|---|
| A | Replace engine oil. |
| A1 | Replace engine oil, plus tire rotation. |
| A13 | Replace engine oil, rotate tires, and perform the transmission-fluid service represented by item 3 for the applicable model. |
Important: Honda's Maintenance Minder definition of A specifies engine-oil replacement. A dealership or repair facility may offer an oil-service package that also includes an oil filter, inspection, or other items. Those package additions should not be confused with Honda's definition of the A main item itself.
An A-code scope is generally narrower than a B-code scope because the A main item does not include the B service's Honda-specified inspection requirements. Actual appointment time depends on any numbered items shown, the vehicle, and any additional work you authorize.
What's Included in a B Service
The B main item includes replacement of the engine oil and oil filter, together with Honda-specified inspections of applicable vehicle systems and components. The exact inspection checklist should be confirmed for the vehicle's model and model year.
Numbered maintenance items can then be added to the B service:
| Code | What's Included |
|---|---|
| B | Replace engine oil and oil filter, plus Honda-specified inspections. |
| B1 | B-service items, plus tire rotation. |
| B12 | B1 items, plus the item-2 maintenance applicable to the vehicle, commonly including air-cleaner and cabin-filter service and drive-belt inspection on applicable models. |
| B123 | B12 items, plus the transmission-fluid service represented by item 3 for the applicable model. |
Note: Maintenance items can appear in different combinations depending on the vehicle. Their exact definitions can also vary by model and model year, and some current Honda models use additional maintenance-item numbers beyond those found on older vehicles. If you're unsure what your exact combination includes, check the owner's manual or have a service advisor confirm the requirements for your VIN. For a more detailed breakdown, see our Maintenance Minder Codes guide.
How the Codes Tend to Sequence
Maintenance Minder does not require a fixed A-B-A-B sequence. Your vehicle may display either main item together with one or more numbered maintenance items based on the system's maintenance calculations and the requirements programmed for that vehicle.
For that reason, the code shown on the dashboard is more useful than trying to predict the next service from a generic mileage chart. Follow the displayed maintenance information and confirm model-specific requirements in your owner's manual.
What Changes by Model
Civic and Accord
Applicable Civic and Accord models use Honda's Maintenance Minder system, but the exact maintenance items and required fluids can vary by model year, engine, transmission, and hybrid or gasoline powertrain. Use the displayed code together with the owner's manual for the exact vehicle rather than assuming every Civic or Accord has an identical service checklist.
CR-V and HR-V
CR-V and HR-V models follow the same general Maintenance Minder concept on applicable vehicles. A CR-V Hybrid still contains a gasoline engine, so engine-oil maintenance remains part of its service requirements. Hybrid-specific components do not eliminate the need to follow the vehicle's displayed maintenance information.
Pilot, Passport, Ridgeline, and Odyssey
These models also use Honda maintenance reminders, but service details can differ by powertrain, drivetrain, model year, and vehicle use. Certain current models can display maintenance-item numbers not used by older Hondas, which is another reason to verify the exact code against the owner's manual rather than relying on a universal list.
Vehicles used regularly for towing, hauling, or other demanding operation may also have maintenance considerations described in their owner's manuals. Follow the requirements for the specific vehicle and how it is being used.
Honda Prologue (Electric)
The Honda Prologue is fully electric and does not have a gasoline engine or require engine-oil changes. As a result, the A/B engine-oil service descriptions in this article should not be used as a maintenance schedule for a Prologue.
Prologue owners should follow the maintenance information and service intervals specified for their exact model year in the Prologue owner's documentation and vehicle maintenance reminders. Its maintenance needs are EV-specific and differ substantially from Honda gasoline and hybrid models.
Why Lake County Driving Conditions Can Matter
Honda's Maintenance Minder is designed to account for vehicle operating conditions rather than relying only on mileage. That means local driving patterns can influence when maintenance information appears. Lake County drivers also face environmental conditions that are worth considering during routine inspections.
Cold-weather operation
Northern Illinois winters can bring extended periods of below-freezing temperatures. Repeated cold-weather operation can be more demanding than steady driving in moderate temperatures, particularly when combined with short trips. Because Maintenance Minder uses vehicle operating conditions in its maintenance calculations, two vehicles with similar mileage may not display service reminders at exactly the same time.
Short-trip suburban driving
School runs, short commutes, errands, and repeated stop-and-go driving around Libertyville, Vernon Hills, Mundelein, and neighboring communities can create a very different operating pattern from long, steady highway trips. This is another reason to follow the vehicle's Maintenance Minder rather than assuming mileage alone determines the next service date.
Road salt and freeze-thaw cycles
Winter road salt, moisture, and repeated freeze-thaw cycles can contribute to corrosion and wear on exposed underbody, brake, exhaust, and suspension components over time. These conditions do not necessarily trigger a specific Maintenance Minder code by themselves, but they make regular visual inspection of affected components particularly useful for vehicles driven year-round in northern Illinois.
Dealer vs. Independent Shop: An Honest Look
Routine maintenance does not generally have to be performed at a franchised dealership simply to keep a manufacturer's warranty in effect. Owners can choose a qualified independent repair facility, provided required maintenance is performed correctly and appropriate service records are retained.
An independent shop can be a reasonable choice for: routine maintenance when the shop understands the Honda service requirements for the specific model and uses parts, fluids, and procedures that meet the applicable specifications.
An authorized Honda dealer can be especially useful when: you need a Honda warranty repair, recall or service-campaign work, Honda-specific diagnosis, help interpreting a model-specific Maintenance Minder code, or access to a complimentary maintenance program or other Honda benefit that requires service through a participating dealer.
Honda Libertyville also offers factory-certified technicians, access to Honda service information, genuine Honda parts, and documented service records. Those can be practical reasons to choose dealer service, but routine maintenance performed elsewhere does not by itself void a factory warranty.
Keep receipts and maintenance records regardless of where the work is performed. If a warranty claim is later made, records can help demonstrate that required maintenance was completed.
Many eligible new Honda vehicles include Honda Service Pass or another complimentary scheduled-maintenance benefit for a defined period. Eligibility and coverage vary by model year, vehicle, program terms, and maintenance item, so confirm the coverage attached to your specific VIN rather than assuming one blanket term applies to every Honda.
What a Service Visit May Cost in Lake County
Pricing depends on the maintenance code, model, parts required, and any additional work you authorize. An A visit and a B123 visit can involve very different service scopes.

Published specials are dealership promotional offers and are not themselves a definition of what every Maintenance Minder code requires. For example, Honda's A main item is defined as engine-oil replacement even though a dealership oil-change package may include an oil filter, inspection, or other added services.
For a specific B123 quote, transmission-fluid price, unusual maintenance-item combination, or repair recommendation, the most accurate price comes from a vehicle-specific estimate. Call (847) 595-5561 or use the scheduling link below to request service information before your visit.

Frequently Asked Questions
Does Honda have a fixed maintenance schedule like 15,000 or 30,000 miles?
Honda Maintenance Minder-equipped vehicles do not rely on one universal fixed-mileage interval for every maintenance visit. The system uses vehicle operating conditions and calculated oil life to indicate when maintenance is due. Always follow the Maintenance Minder display and the owner's manual for your specific model and model year.
What's the difference between an A service and a B service?
Honda defines the A main item as replacement of the engine oil. The B main item includes replacement of the engine oil and oil filter plus Honda-specified inspections. Numbered maintenance items can appear alongside either main item and identify additional maintenance that is due.
Can I skip a numbered maintenance item if I don't think I need it?
You can decide which maintenance or repair work to authorize, but a numbered Maintenance Minder item indicates that Honda's maintenance system lists that service as due for the vehicle. It should not be interpreted as a sensor directly diagnosing that a particular component has failed or worn out.
If you're unsure why an item is displayed, check the owner's manual for your model and model year or ask a service advisor to explain the required procedure before you authorize the work.
My Prologue doesn't follow the A/B oil-service information. Is that normal?
Yes. The Prologue is a battery-electric vehicle and does not have a gasoline engine or require engine-oil changes. The A/B engine-oil descriptions used for Honda gasoline and hybrid vehicles should therefore not be treated as the Prologue's maintenance schedule. Follow the maintenance information provided for your specific Prologue model year.
Why did my maintenance reminder appear earlier than I expected?
Maintenance Minder does not use mileage alone. Vehicle operating conditions influence its maintenance calculations, so two similar Hondas can display maintenance reminders at different odometer readings. Driving patterns that involve frequent short trips, stop-and-go operation, or demanding conditions can differ significantly from steady highway driving.
Do I have to use a Honda dealer to keep my factory warranty?
No. Routine maintenance or repairs performed by an independent repair facility do not, by themselves, void a manufacturer's warranty. Required maintenance still needs to be performed properly, and owners should keep service records and receipts. Warranty coverage may be affected if damage is caused by improper service or a defective or incorrectly installed part.
Does Honda Service Pass cover A and B visits?
Honda Service Pass or other complimentary scheduled-maintenance coverage may apply to eligible vehicles and maintenance services. Coverage varies by model year, vehicle, and program terms, so confirm the benefits attached to your specific VIN with a Honda dealer rather than assuming all A or B services are automatically covered.
