Honda Maintenance Minder Codes Explained and Service in Victorville

November 2nd, 2026 by

That little code on your Honda’s dash, like A1 or B12, is the Maintenance Minder telling you what your car needs. Here is what the codes mean according to Honda, when to book service, and what our Victorville service department can handle for you.

  • Under 15% oil life: Honda says Maintenance Minder messages start to appear.
  • A and B: the two main service codes, with numbers 1 through 7 added for other items.
  • Every 12 months: Honda says to change the oil yearly if no message has appeared since the last reset.

How the Maintenance Minder Works

Honda says the Maintenance Minder works out your remaining engine oil life from the way the engine operates, then shows it as a percentage. It also shows codes for other maintenance items that should be done at the same time as your next oil change. Because it responds to how you drive, two Hondas can reach a service message at very different mileages.

What the Codes Mean

This table follows the maintenance items printed in Honda’s owner information for U.S. models. Your exact list can differ by model and model year, so your Owner’s Manual is the final word.

Code What Honda lists Notes
A Replace engine oil The basic oil change service
B Replace engine oil and oil filter, inspect front and rear brakes, plus other inspections Honda’s list also includes tie rod ends, steering gearbox and boots, suspension components, brake hoses and lines, fluid levels, exhaust system and fuel lines
1 Rotate tires Added to A or B
2 Replace air cleaner element and dust and pollen filter, inspect drive belt Added to A or B
3 Replace transmission fluid Added to A or B
4 Replace spark plugs, inspect valve clearance Added to A or B
5 Replace engine coolant Added to A or B
6 Replace rear differential fluid Added to A or B
7 Replace brake fluid Added to A or B

Summarized from Honda’s published owner information for U.S. models. Maintenance items and code numbers vary by model and model year. Refer to your Owner’s Manual or ask our service team.

A code like B12 simply means you have service B plus items 1 and 2: oil and filter, brake and other inspections, tire rotation, and the air cleaner element and dust and pollen filter.

When to Book Service

According to Honda, once your remaining oil life drops below 15 percent, the Maintenance Minder messages appear each time you turn the vehicle on. Honda describes three stages:

  • Due soon: 15 to 6 percent oil life remaining. Items should be inspected and serviced soon.
  • Due now: 5 to 1 percent remaining. Items should be inspected and serviced as soon as possible.
  • Past due: a negative distance appears after more than 10 miles of driving, and Honda says the items must be inspected and serviced immediately.

Honda’s page does not set a mileage or day count for how long you can wait once the message first appears, so the simplest plan is to book when you first see it. There is also a time backstop. Honda says that if no message appears more than 12 months after the display was reset, change the engine oil every year. The brake fluid has its own limit: if no message appears more than 36 months after that item was reset, Honda says to change brake fluid every 3 years.

After service, the display needs to be reset. Honda warns that skipping the reset leads to incorrect maintenance intervals. After a visit, ask our service team to confirm the display was reset.
