Honda CR-V Maintenance Minder Codes Explained
Honda CR-V Maintenance Minder codes are made of one letter and, sometimes, one or more numbers. The letter is the main service: A means replace the engine oil, and B means replace the oil and filter and carry out a set of brake, steering, suspension and fluid inspections. The numbers are add-on jobs due at the same visit, from 1 (rotate the tires) to 7 (replace the brake fluid), so a code like B13 means oil and filter, inspections, a tire rotation and a transmission fluid change.
The Minder has been part of every CR-V since the 2007 model year. Below is what each code means, how to read combinations, and the few details that change from one generation to the next.

Main Codes: A and B
The letter always appears first and always involves the engine oil. Which letter you see depends on whether the filter and inspections are also due.
Code A: replace engine oil
An A service is the shortest visit: drain and refill the engine oil. Honda’s schedule does not call for a new filter at an A service, although many shops fit one anyway because the cost is small.
Code B: oil, filter and inspection
A B service includes everything in A plus a new oil filter and a list of checks. Honda’s US owner’s manuals list these items under B:
- Inspect front and rear brakes
- Check parking brake adjustment
- Inspect tie rod ends, steering gearbox and boots
- Inspect suspension components
- Inspect driveshaft boots
- Inspect brake hoses and lines, including ABS/VSA
- Check all fluid levels and fluid condition
- Inspect the exhaust system
- Inspect fuel lines and connections
Because the brakes are inspected at every B service, this is usually when a shop will tell you how much pad material is left. Our guide to Honda CR-V brake pads explains what those measurements mean.
Canadian vehicles: 0 and 9
If you bought a CR-V from Canada, or are reading a Canadian manual, you may see a 0 instead of B. Honda’s Canadian schedule splits the B service in two: 0 means replace the oil and filter, and sub-item 9 covers the brake service and the same inspection list. A Canadian “09” therefore asks for the same work as a US “B.” US-market CR-Vs use A and B.
Sub-Item Codes 1–7
Sub-items appear after the letter, and more than one can show at once. The table lists what each number calls for on the CR-V.
| Code | Service required | Notes for CR-V owners |
|---|---|---|
| 1 | Rotate tires | Follow the rotation pattern in the owner’s manual. |
| 2 | Replace air cleaner element, replace dust and pollen (cabin) filter, inspect drive belt | Honda adds a footnote: replace the engine air filter every 15,000 miles in dusty conditions, and the cabin filter every 15,000 miles in high-soot urban areas, regardless of the Minder. |
| 3 | Replace transmission fluid | Applies to both the older automatic and the CVT used from 2015 on; the fluid type differs. |
| 4 | Replace spark plugs, inspect valve clearance | Honda says to adjust valves only if they are noisy. |
| 5 | Replace engine coolant | Use Honda Long Life Antifreeze/Coolant Type 2 or the coolant listed in your manual. |
| 6 | Replace rear differential fluid | AWD models only; FWD CR-Vs will not show this item. |
| 7 | Replace brake fluid | Shown on newer CR-Vs. On 2007–2016 models brake fluid is not a Minder item; Honda says to replace it every 3 years regardless of the display. |
Fluid details for each of these jobs are in our CR-V transmission fluid guide, engine coolant guide and brake fluid guide. Always check the owner’s manual for your specific vehicle, because the list can vary by year and drivetrain.
How to Read Common Combinations
Read the code left to right: letter first, then each number as a separate job. A few that CR-V owners see often:
- A1: oil change and tire rotation.
- B1: oil and filter, full inspection, tire rotation.
- B12: the B1 service plus a new engine air filter and cabin filter and a drive belt inspection.
- B13: the B1 service plus a transmission fluid change.
- A17 or B17: oil service and tire rotation plus a brake fluid replacement (on models that use item 7).
- B1236 or similar: several items have come due together, which is common at higher mileage. It is still one visit; it simply has more line items.
When the Codes Appear
The Minder ties every code to the engine oil life percentage. When remaining oil life drops to 15%, the wrench icon and the code appear, telling you service is due soon. At 5% it is due now, and at 0% it is overdue; the display then counts negative miles. The wrench icon and related warnings are covered in our CR-V dashboard symbol guide.
Sub-items do not have their own countdown on the display, but the system tracks them in the background and attaches them to whichever oil service comes next. That is why a code can jump from A1 at one visit to B12 at the next: the Minder grouped the jobs that will be due before the following oil change.
Time-based limits still apply
Two Honda footnotes override the display. If the Minder has not called for an oil change within 12 months of the last reset, change the oil anyway. And on models without item 7, brake fluid is replaced every 3 years no matter what the screen says. For how often oil typically comes due and which grade to use, see our Honda CR-V oil change interval guide.
How to Reset a Maintenance Minder Code
Dealers and most shops reset the codes after the work is done. If you do the work yourself, reset only the items you completed. The general sequence on Minder-equipped CR-Vs is below; the exact buttons depend on the year and instrument cluster, so use the procedure in your owner’s manual.
- Turn the ignition on with the engine off.
- Bring up the oil life or maintenance screen on the driver information display.
- Press and hold the select/reset button (or the steering-wheel selector on newer models) until reset mode opens.
- Select either “all due items” or the individual item you serviced, such as item 1 after a tire rotation.
- Confirm, then check that the code you cleared is gone and oil life reads 100% if you reset the oil.
What the Minder Does Not Track
The Minder is not a complete maintenance list. It does not watch tire tread depth or tire pressure, wiper blades, the 12-volt battery or brake pad wear between B inspections. It also does not know whether you tow, drive dusty roads or sit in heavy traffic beyond what its sensors infer, which is why Honda still prints severe-condition footnotes for the air filters. Use the codes as the backbone of your routine and add visual checks between visits. Our CR-V and CR-V Hybrid maintenance schedule shows how the codes fit into a full year of care.
FAQ
Is it safe to drive with a Maintenance Minder code showing?
Yes, in the short term. The code is a scheduling reminder, not a fault warning. At 15% you have time to book an appointment. Once the display reaches 0% and starts counting negative miles, the service is overdue and should be done promptly.
What is the difference between A and B on a CR-V?
A is an oil change only. B is an oil and filter change plus inspection of the brakes, parking brake, steering, suspension, driveshaft boots, brake lines, exhaust, fuel lines and all fluid levels. B visits take longer and cost more.
Why does my CR-V show 0 instead of B?
Code 0 is used on Canadian-market Hondas. It means oil and filter replacement, and it is usually paired with sub-item 9, which covers the brake service and inspections that the US B code includes.
Do I have to go to a Honda dealer for Maintenance Minder services?
No. Any qualified shop can do the work. Keep receipts showing the date, mileage and work done, and make sure the shop uses the fluids and parts specified in your owner’s manual.
Summary
On a CR-V, the letter tells you what happens to the oil (A for oil, B for oil, filter and inspection) and each number adds a job: 1 tires, 2 filters and belt, 3 transmission fluid, 4 spark plugs, 5 coolant, 6 rear differential fluid and 7 brake fluid. Book the service when the code appears at 15%, reset only what you actually completed, and keep the two time-based rules in mind: oil at least once a year and brake fluid every three years.
