Honda Maintenance Minder Codes

In order to ensure that your Honda vehicle continues to operate at peak performance, the first step is to have routine maintenance completed at your Honda dealer. Honda understands that it can sometimes be confusing to understand which maintenance services your vehicle requires at any given mileage interval. That’s exactly why the Maintenance Minder System was introduced.

Every Honda model has its own specific maintenance needs which can vary based on factors like the engine type, transmission type, or the addition of a towing package. All of these factors are taken into consideration by Honda through the development of specific maintenance schedules. These guidelines help prevent problems before they occur and make it easy to give your Honda the attention and care that it deserves.

Understanding the Maintenance Minder System

When your engine oil needs replacing and maintenance is due, the Maintenance Minder System will display remaining engine oil life in the information display. It’s shown as a percentage, starting with 100% oil life. This percentage will gradually wind down to 0% over time as you drive, indicating that the oil life has been depleted. You’ll find a list of Messages, Main Items, and Sub Items listed below along with a definition about what each means.


Oil Life 15% – Service is due soon. Now is a great time to schedule an appointment with Honda East for scheduled maintenance services.

Oil Life 5% – Service is due now. As soon as possible, you should take your vehicle to Honda East for scheduled maintenance.

Oil Life 0% – Service is past due. You will also see a mileage readout which indicates how far overdue you are for service. To avoid harmful wear or damage, take your vehicle in for service now.

Maintenance Main Items – Symbols

A – Indicates engine oil should be replaced.

B – Indicates engine oil and filter should be replaced. Inspections of various systems and components should also be done. See your owner’s manual for additional details.

Maintenance Sub Items – Numbers

1 – Rotate tires, verify correct tire pressure and condition.

2 – Replace air cleaner element, inspect drive belt, and replace dust and pollen filter.

3 – Replace transmission fluid and transfer fluid (if equipped).

4 – Replace spark plugs, timing belt (if equipped), inspect water pump, and inspect valve clearance.

5 – Replace engine coolant.

6 – Replace rear differential fluid (if equipped).

Decoding the Maintenance Minder System

Now that you have an understanding of what exactly the Messages, Main Items, and Sub Items mean — here’s an example of how to decode the entire system message.

Let’s say your Honda Maintenance Minder Message display an illuminated orange wrench along with the code “A3”. “A” is a Main Item which tells you that your engine oil should be replaced. “3” is a Sub Item which indicates that it’s time to replace your vehicle’s transmission fluid and transfer fluid (if equipped).

Another important thing to remember is that while a Main Item will always be displayed in the message, Sub Items are only periodically displayed because these are based on a time and mileage interval. It’s also possible for the message to display several Sub Items (example – A129). Every additional Sub Item simply represents another indicated service. For this example, you would need Sub Items 1, 2, and 9.
