Acura maintenance codes: Maintenance Minder chart
Acura maintenance codes come from the Maintenance Minder, the same system Honda uses. Each code is a letter, sometimes followed by numbers. A means replace the engine oil. B means replace the oil and the oil filter and inspect the car. Each number adds one job, such as 1 for a tire rotation or 2 for new air filters. So an Acura B1 service is an oil and filter change, an inspection, and a tire rotation.

How an Acura code works
When oil life drops to 15%, the display shows a maintenance message with a code. Read the letter as the main job, then each digit as a separate extra job: B12 is B plus 1 plus 2, not item 12. The system picks the codes from how the engine has been used, so there is no fixed mileage for any code.
The 2024 Integra manual shows the oil life steps:
| Display | Message | What it means |
|---|---|---|
| 15% | Maintenance Due Soon | 15 to 6% oil life left: book the service |
| 5% | Maintenance Due Now | 5 to 1% left: service as soon as you can |
| Negative distance | Maintenance Past Due | Oil life is used up; after more than 10 miles past 0% the distance blinks |
Main codes: A and B
| Code | What Acura lists |
|---|---|
| A | Replace the engine oil. |
| B | Replace the engine oil and oil filter. Inspect the front and rear brakes. Check the expiration date of the tire repair kit bottle. Inspect the tie rod ends, steering gearbox, and boots; suspension parts; driveshaft boots; brake hoses and lines (including ABS/VSA); all fluid levels and condition; the exhaust system; and fuel lines and connections. |
From the 2024 Integra owner’s manual. Older and larger models may also list a parking brake check under B. Your manual is the final word.
A time rule applies to both: if no Maintenance Minder message appears more than 12 months after the last reset, change the engine oil anyway.
Sub codes: 1 to 7
| Number | Job | Only on some models |
|---|---|---|
| 1 | Rotate the tires | — |
| 2 | Replace the engine air filter and the cabin air filter; inspect the drive belt | — |
| 3 | Replace the transmission fluid | Also transfer fluid on V6 all-wheel-drive models; clutch fluid on manual-transmission models |
| 4 | Replace the spark plugs; inspect the valve clearance | Timing belt replacement and water pump inspection on V6 engines |
| 5 | Replace the engine coolant | — |
| 6 | Replace the rear differential fluid | All-wheel-drive models; twin motor fluid on hybrid all-wheel-drive models |
| 7 | Replace the brake fluid | — |
The base list is the 2024 Integra (front-wheel drive, four-cylinder, no item 6). The model notes come from Acura Canada’s Maintenance Minder schedules. Check your owner’s manual for your car.
Brake fluid has a time limit too: if code 7 has not appeared within 36 months of its last reset, change the brake fluid every 3 years.
Acura B1, A1, B12, B13 and other common codes
Acura codes mean the same jobs as Honda codes, so the Honda code pages apply. Here is what the common Acura codes ask for:
| Code | Jobs | More detail |
|---|---|---|
| A | Oil change only | — |
| A1 | Oil change and tire rotation | A1 service |
| B1 | Oil and filter change, inspection, tire rotation | B1 service |
| A12 | Oil change, tire rotation, both air filters | A12 service |
| B12 | B1 plus both air filters | B12 service |
| B2 | B service plus both air filters, no rotation | — |
| B13 | B1 plus transmission fluid | B13 service |
| A13 | A1 plus transmission fluid | A13 service |
| B123 | B1 plus air filters and transmission fluid | B123 service |
| B14 | B1 plus spark plugs and valve check (and timing belt on V6) | B14 service |
| B16 | B1 plus rear differential fluid (all-wheel drive) | B16 service |
| B17 | B1 plus brake fluid | B17 service |
A dealer “Acura A service” or “B service” on a menu usually means the letter with no numbers. Ask for a written estimate that lists each item, and match it to the code on your display.
Codes on Canadian Acuras: 0 and 9
Canadian Acuras can show different main codes. On newer models, Acura Canada uses A and 0 instead of A and B: 0 means replace the oil and the oil filter, and the brake service and inspection list moves to a separate code 9. Acura Canada lists this “A/0” type for the 2019 and newer RDX, 2021 and newer TLX, 2022 and newer MDX, 2023 and newer Integra, and 2025 and newer ADX. So a Canadian “09” visit covers about the same jobs as a U.S. “B.” If you bought your Acura in Canada, use the Canadian table in your manual.
Hard driving the system does not sense
The Maintenance Minder does not know about dust, heavy towing, or long slow climbs. Acura gives fixed limits for those:
- Dust or soot: replace the engine air filter or the cabin filter every 15,000 miles (2024 Integra).
- Slow mountain driving: change the transmission fluid every 25,000 miles on the Integra CVT, or 37,500 miles with the manual transmission.
- Towing or mountains on all-wheel-drive models: Acura Canada says to change the differential fluid at 12,000 km (about 7,500 miles), then every 24,000 km (about 15,000 miles).
- Extreme temperatures on V6 engines: Acura Canada says to replace the timing belt every 100,000 km (about 62,000 miles) if the car is often used above 43°C (109°F) or below −30°C (−22°F).
Your manual has the exact numbers for your model.
Reset and record
The dealer resets the display after the service. If someone else does the work, reset it yourself; on the 2024 Integra you open the Maintenance Minder screen and hold the right selector wheel for about 10 seconds. Steps differ by model, so follow your manual. Acura warns that skipping the reset makes the system show the wrong intervals.
Then log the date, odometer, code, and price in a car maintenance log. For the time rules and warranty, see the Acura maintenance schedule. For the full Honda version of this chart, see Honda maintenance codes.
FAQ
Are Acura maintenance codes the same as Honda’s?
Yes. Acura is Honda’s luxury brand and uses the same Maintenance Minder: A and B for the main service and 1 to 7 for extra jobs. The item list for your model is in your Acura owner’s manual.
What is an Acura B1 service?
An engine oil and oil filter change, an inspection of the brakes, steering, suspension, fluids, exhaust, and fuel lines, and a tire rotation.
How much does an Acura B1 service cost?
There is no set price. As a rough guide, an oil and filter change runs about $64 to $118 (AAA shop survey, scaled to late 2026) and a tire rotation about $45 to $75 (Consumer Reports), so about $109 to $193. Dealer labor rates and the oil your engine takes move the total. See oil change cost.
Why does my Acura show 0 or 9 instead of B?
It is likely a Canadian model. On newer Canadian Acuras, 0 means oil and filter, and 9 means the brake service and inspection. Together they match the U.S. B service.
