Your Quick Acura Maintenance Codes Overview

Acura maintenance codes are different from diagnostic trouble codes: Trouble codes use icons to tell you your engine needs to be checked, fluids are too low, or cylinders are misfiring, while maintenance codes appear as a combination of letters and numbers to remind you of your vehicle's service needs. You can think of Acura maintenance codes like a digital owner's manual – instead of checking your model's recommended service schedules and manually adding them to your to-do list, your car does the legwork for you.

What Is the Acura Maintenance Minder System?

Acura maintenance codes are part of the high-tech Acura Maintenance Minder system. This sophisticated system monitors your model's health and makes recommended service suggestions that let you know when to book service. How does the Acura Maintenance Minder work? It uses real-time data from your car, runs it through an algorithm based on typical maintenance schedules, and tells you exactly what areas of your vehicle need attention.

What Do Acura Maintenance Codes Stand For?

Acura maintenance codes display on your driver information screen as letters (main codes), sometimes followed by numbers (sub-codes). These letters and numbers indicate the specific maintenance needed for your vehicle. While some sub-code numbers stand for multiple checks and inspections, you'll still better understand which systems are due for a check-up. For example, if you drive an Acura MDX, service code A1 might appear to tell you that it's time for an oil check and tire rotation! You may also see the words "Oil Life" displayed on your dash – the percentage shown tells you how quickly you need to change your oil.

You can also refer to your owner's manual for a refresher on Acura maintenance codes and their meanings. For example, in the Maintenance Minder section of your Acura RDX manual, you'll see that B6 means replacing your engine oil and oil filter, inspecting many portions of your vehicle, and replacing your rear differential brake fluid. Meanwhile, a 2025 Integra owner doesn't need rear differential brake fluid and, therefore, won't have the "6" maintenance sub-code. To clarify how these codes work and help you identify your car's issues, here's an updated 2025 Acura Maintenance Minder codes reference chart.
