How to Read Maintenance Minder Codes on Your 2021 Honda Odyssey
Your 2021 Honda Odyssey shows Maintenance Minder codes on the dashboard display between the speedometer and tachometer. Start the engine to see the oil life percentage and codes like A1. A tells you to change engine oil. The 1 adds tire rotation.
Oil life starts at 100% after service. It drops based on your driving habits. Short trips or dusty roads speed up the drop. The system checks engine heat, speed, and miles. At 15% oil life, get service soon. At 5%, service now. Hit 0% and you risk engine damage that costs over $2,000 to fix.
Honda tailors services to your needs with these codes. Main codes handle major tasks. Sub codes cover extras.
Main Codes
| Code | Service |
|---|---|
| A | Change engine oil every 7,500 to 10,000 miles. |
| B | Change engine oil and oil filter. Inspect brakes, steering, suspension, and driveshafts. |
Sub Codes
| Code | Service |
|---|---|
| 1 | Rotate tires every 5,000 to 8,000 miles. |
| 2 | Replace air cleaner element. Inspect drive belt. |
| 3 | Replace dust and pollen filter. |
| 4 | Replace spark plugs, timing belt if equipped, check valve clearance. |
| 5 | Replace engine coolant. |
| 6 | Replace rear differential fluid on AWD models. |
| 7 | Replace brake fluid every 3 years. |
Follow these steps to read and act on codes:
- Turn the ignition to ON or start the engine.
- Look at the oil life percentage and full code, like B2.
- Match the letter to the main service. Handle A or B oil changes first.
- Add sub code tasks. B2 means oil, filter, inspections, air cleaner replacement, and drive belt check.
- Schedule service before oil life reaches 0%.
Shops reset codes after work. You can reset yourself. Turn ignition to ON. Press and hold the Select/Reset button for 10 seconds until oil life shows 100%. Check your owner's manual for your trim's exact steps.
Oil changes cost $50 to $90. Tire rotations cost $20 to $40. Skip services and pay big for repairs. Regular care keeps your Odyssey safe and reliable for years.
