Honda Maintenance Minder Codes Explained
Seeing a wrench and a code such as A1, A12, A13, B1 or B12 on your Honda dashboard? The letter identifies the main maintenance service, while each number represents an additional service item. Use the Honda Maintenance Minder code chart below to find out what service your vehicle needs.
Honda’s Maintenance Minder monitors factors such as mileage, engine operating conditions and vehicle equipment to determine when maintenance is due. Because service requirements can vary by Honda model, model year and equipment, consult your owner’s manual or contact Honda East Cincinnati to confirm the recommended service.

Understanding the Maintenance Minder System
The Maintenance Minder System displays engine oil life in the information display, notifying drivers when the engine oil needs replacing and maintenance is due. Engine oil life is shown as a percentage, starting with 100% oil life. It will gradually wind down to 0% over time as you drive, signaling the oil life is depleted. Listed below, you’ll find a list of Messages, Main Items, and Sub Items along with what each means.
Messages
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 we’ve covered exactly what the Messages, Main Items, and Sub Items mean — here’s an example of how to decode the entire system message.
For example, your Honda Maintenance Minder Message displays an illuminated orange wrench followed by the code “A3”. “A” is a Main Item which would indicate that your engine oil should be replaced. “3” is a Sub Item which suggests that it’s time to replace your vehicle’s transmission fluid and transfer fluid (if equipped).
There will always be a main item—A or B—in the Maintenance Minder message. Numbered sub-items appear when additional services are due. For example, code A13 combines main item A with sub-items 1 and 3, indicating an engine oil change, tire rotation and transmission-fluid replacement.
