2020 Honda CR-V showing B12 on the Maintenance Minder. What's included and how to reset it?

Answered from the manual for the 2020 Honda CR-V.

B12 does not require a dealer if you are equipped to perform the work and inspections properly. It means:

• B: Replace engine oil and oil filter; inspect the front and rear brakes; inspect tie-rod ends, steering gearbox and boots, suspension components, driveshaft boots, brake hoses/lines including ABS/VSA, all fluid levels and fluid condition, exhaust system, and fuel lines/connections.
• 1: Rotate tires.
• 2: Replace the engine air-cleaner element and cabin dust/pollen filter, and inspect the drive belt.

So the filters, oil/filter change, and tire rotation are typical DIY jobs. The B-code brake/chassis/fluid/exhaust inspections are also part of the service, so use a shop if you cannot safely inspect those items. Honda also says to adjust valves during B, 1, or 2 service if they are noisy.

Reset after completing the work:

1. Switch the ignition to ON (do not start). On push-button models, use the ENGINE START/STOP button to select ON.
2. Press the display/information button until the Maintenance Minder screen appears.
3. Press ENTER.
4. Hold ENTER for about 10 seconds.
5. Use the arrow controls to choose the individual completed item(s), or All Due Items.
6. Press ENTER to reset; repeat for any other item needed.

Honda specifically says to reset the display when maintenance is performed; otherwise the displayed intervals will be incorrect.
