Clearing A1 on a Honda means resetting the Maintenance Minder after service. Use the vehicle’s maintenance display and the reset controls to clear the code; the exact steps depend on your model year. This guide explains how to reset A1 on common Honda models and what the code typically means.
What A1 means in Honda Maintenance Minder
Honda’s Maintenance Minder uses letters and numbers to indicate when service is due. The “A” portion usually relates to an engine oil change, while the “1” denotes one additional maintenance item that is due. The exact item linked to the “1” can vary by model and year, such as tire rotation, engine air filter replacement, or cabin air filter inspection. Since the precise tasks tied to A1 differ across Civics, Accords, CR-Vs and other models, always check your owner's manual or the maintenance minder screen for your exact vehicle.
Model-year and model-specific caveats
Because Honda updates maintenance items by generation, the exact A1 definition isn’t universal. If you’re unsure what the “1” item refers to on your car, consult the maintenance minder display, your owner’s manual, or a Honda dealer to confirm the due tasks for your VIN and year.
Resetting A1 on older Honda models (pre-2016 common layouts)
Older Hondas often use a physical SEL/RESET knob or buttons on the instrument cluster to reset maintenance figures. Use these steps as a general guide for vehicles with a traditional gauge cluster.
- Turn the ignition to ON with the engine OFF (accessory power, not启动). This powers the gauge cluster without starting the engine.
- Navigate to the Maintenance Minder or maintenance screen using the selector knob or trip/INFO buttons on the instrument cluster.
- Select the current maintenance item (A1) if requested, then choose Reset or press and hold the SEL/RESET knob until the display resets.
- Release the controls and confirm that the display shows the maintenance minder has been cleared or reset to zero.
- Turn the ignition OFF, then start the engine to verify the A1 indicator no longer appears.
After performing these steps, the A1 indicator should disappear from the dash and the maintenance interval should reset. If the code remains, repeat the process slowly or consult the manual for your exact year and trim.
Resetting A1 on newer Honda models (2016 and later, digital dash)
Newer Hondas use a multi-information display with steering-wheel controls. These steps cover most 2016+ Civics, Accords, CR-Vs and related models that rely on the MMI/menu system to reset maintenance.
- With the ignition in RUN and the engine off, press the Home/Info or Menu button on the steering wheel to access the Maintenance Minder menu.
- Use the selector wheel or arrows to navigate to MAINTENANCE INFO or MAINTENANCE, then select Reset or Reset Items.
- Highlight the A1 item (or the current maintenance item due) and confirm the reset when prompted. Some models require you to choose “Yes” or press and hold the SEL/RESET control for confirmation.
- Wait for the screen to indicate the maintenance item has been reset, usually returning to a normal display or showing “0” days/0 miles until the next due service.
- Turn the ignition OFF, then start the engine to ensure the A1 alert is cleared from the display.
Note: On some models, you may need to navigate to a sub-menu like “CUSTOMIZE MAINTENANCE” before you can choose Reset. If a reset option isn’t visible, perform the reset after servicing or contact a dealer for assistance.
Tips for a smooth reset
Always reset only after the scheduled maintenance has been completed. Resetting without performing the service can mask overdue maintenance and potentially affect your vehicle’s reliability and warranty.
What to do if reset fails or is unclear
If you cannot reset A1 using the common methods described, try these steps: double-check the exact model year, consult the owner’s manual for maintenance minder instructions specific to your vehicle, or contact a Honda dealer or certified shop. Some models require a specific sequence or a service reset from the shop diagnostic tool, especially if the system has been flagged for more complex maintenance tasks.
Summary
Clearing A1 involves resetting Honda’s Maintenance Minder after you’ve completed the required service. The exact steps depend on the model year and dashboard setup—older cars use a physical reset knob, while newer models use the steering wheel controls and a digital maintenance menu. Always verify that maintenance has actually been performed before resetting, and consult your owner’s manual or a Honda dealer if you’re unsure about the correct process for your vehicle.
