Honda Maintenance Minder Codes & What They Mean

Many modern Honda vehicles utilize Honda Maintenance Minder codes to simplify your maintenance schedule. Rather than needing to study a potentially complicated chart of dates, times, and work, this system – available on most modern Honda models – provides an easy-to-follow code lineup accessible for any Honda dealer. But if you're unfamiliar with the codes, how will you know what your car, truck, or SUV needs? Luckily, the Muller Honda Highland Park in Highland Park, IL, team is here to help.

What Is the Honda Maintenance Minder?

The Honda Maintenance Minder produces a message that you can see on your driver information display. This message will typically depict a wrench and an "i" icon in a circle. Beneath the wrench, a series of letters and numbers tells you exactly what your Honda car, truck, or SUV will need in the near future to prevent issues from cropping up.

Our Honda service department can make an appointment based solely on the letters and numbers that your Honda vehicle produces. However, if you want to understand for yourself – whether for DIY projects or to simplify the appointment process – we've crafted a small chart of the most popular codes in American-built Honda vehicles.

Honda Maintenance Minder Code Chart

The Maintenance Minder codes are arranged by letters and numbers: A and B and the numerals 1 through 7. Here's a look at what they mean:

Letter Codes		Number Codes
Code	Explanation	Code	Explanation
A	Replace engine oil	1	Rotate tires
B	Replace engine oil and oil filter Inspect and potentially replace the following components: Front and rear brakes Any external equipment, such as tire repair bottle kits Tie rod ends, steering gearbox, boots Parking brake adjustment Suspension Driveshaft boots Brake hoses and lines Fluid levels and condition of fluids Exhaust system Fuel lines and connections	2	Replace air cleaner element Replace dust and pollen filter Inspect drive belt
		3	Replace transmission fluid
		4	Replace spark plugs Replace timing belt and inspect water pump Inspect valve clearance
		5	Replace engine coolant
		6	Replace rear differential fluid
		7	Replace brake fluid

These letters and numbers can be paired. For example, A1 will tell you to get an oil change and a tire rotation. B3 represents the need for an oil change and a new oil filter, along with transmission fluid replacement. You might even see something like B123, which bundles several necessary service needs found in our chart.

Where Is the Maintenance Minder Indicator?

The Maintenance Minder indicator is a screen on your driver information display, represented by a wrench and "i" icon whenever there's a maintenance item on your schedule. Depending on your vehicle, this is placed adjacent to an oil life message, measured in percentages. Once your oil reaches 15% life, this warning will appear whenever you set the power of your vehicle to ON – or it can be accessed by customizing your driver information display through the selector controls on your steering wheel.

The indicator has three messages that can be paired with it:

Maintenance Due Soon: This means that the maintenance items are coming up, and it is recommended to schedule service or inspection soon.
Maintenance Due Now: You should make plans to get the requested service items performed as soon as possible to avoid wear or damage to your vehicle.
Maintenance Past Due: The service items should be done immediately to avoid more expensive damages or, in the worst-case scenario, an accident caused by brake pad or suspension issues.

This support system works through expected mileage milestones and oil levels; if you drive in more intensive conditions, you may need to inspect your transmission or differential fluid more often.

Are Honda Maintenance Minder Codes for Every Model?

Honda Maintenance Minder codes are not universal. Some vehicles, like the Honda Ridgeline, have additional items to inspect for code B (Check parking brake adjustment) and Code 2 (Inspect drive belt). A Honda Civic Sedan will never produce a Code 6, since that is only for AWD models that require their rear differential fluid to be replaced. Older Honda models from 2007 to 2015 may not necessarily have a Maintenance Minder system installed, nor do all modern models. Before searching for your Maintenance Minder screen, please refer to your owner's manual for compatibility information.
