Resetting dashboard lights on a 2018 Honda Accord is usually about two routine items: the Maintenance Minder (oil life) reset and the Tire Pressure Monitoring System (TPMS) reset. Other warning lights should be addressed rather than simply reset, as they point to real issues.
In this guide, you’ll find practical, step-by-step instructions for the most common resets you’re likely to perform yourself, plus guidance on what to do if lights stay on after a reset.
Resetting the Maintenance Minder (oil life)
To reset the oil-life indicator on most 2018 Accord models, use the instrument panel controls as described below.
- Turn the ignition to ON (II) with the engine off and all accessories off.
- Locate the SELECT/RESET knob on the instrument cluster and use it to highlight the Oil Life display.
- Press and hold the SELECT/RESET knob until the Oil Life indicator blinks and resets to 100%.
- Release the knob, turn the ignition off, then back to ON and verify the oil life shows 100%.
After completing these steps, the maintenance reminder should be reset and won’t appear until the next service interval is due.
Resetting the Tire Pressure Monitoring System (TPMS)
Resetting TPMS is typically achieved by inflating the tires to the recommended pressures and allowing the system to relearn, though some trims may offer a reset option in the vehicle settings. Follow these general steps.
- Check and adjust all tire pressures to the recommended values shown on the door jamb placard, including the spare if your model uses it for TPMS relearn.
- Inspect tires for leaks or damage and correct any issues before proceeding.
- Drive the vehicle at speeds above about 50 mph (80 km/h) for 10 minutes or longer to trigger a relearn by the TPMS.
- If your model provides a TPMS Reset option in the driver information display or settings menu, you can follow that menu to perform a relearn; otherwise, the light should eventually reset automatically after a successful relearn drive.
If the TPMS warning light remains on after inflating and driving, there may be a faulty sensor or a calibration issue that a dealer or qualified technician should address.
Other dashboard warning lights: what to do
Not all warning lights should be reset. Some indicate real problems that require diagnosis and repair. Here are common lights you might see and general guidance on handling them.
- Check Engine / Powertrain: Have the codes read with an OBD-II scanner or by a mechanic; address the root cause rather than trying to erase the light.
- ABS / Traction control: Indicates a braking or stability system issue; seek service if the light stays on.
- Brake System: Low brake fluid or another brake system fault; inspect immediately and top up if needed, then have the system checked.
- TPMS: Follow the tire-pressure steps above if the light stays on after inflating to spec.
- Maintenance Minder: If the reminder persists after reset, it may indicate a due service; schedule maintenance to restore optimal performance.
In general, reset attempts should not replace professional diagnostics for warning lights that persist or reappear after resets.
Additional notes about resets
Some 2018 Accord trims include more advanced settings in the driver information display. If you have a trim with customizable TPMS or maintenance settings, consult the owner’s manual for the exact menu path and any model-specific steps.
When in doubt, or if lights indicate a potential safety issue, contact a Honda service center for a diagnostic. Resetting should come after you’ve confirmed that the underlying issue has been addressed.
Summary
For most owners, the two routine dashboard-light resets on a Honda Accord 2018 are the Maintenance Minder oil-life reset and the TPMS relearn. The oil-life reset involves turning the ignition on (without starting) and holding the SELECT/RESET control until the display returns to 100%. The TPMS reset generally requires inflating tires to the recommended pressures and driving at highway speeds for a short period to relearn, with some trims offering a menu-based reset. Other warning lights should not be reset without addressing the root cause; if a warning persists, seek professional service to diagnose and fix the underlying issue.
