Honda Passport maintenance schedule
The Honda Passport maintenance schedule comes from the Maintenance Minder, which shows a letter and numbers such as B12 when service is due. The Passport uses sub-codes 1 through 7: code 7 is brake fluid, which the related Ridgeline handles on a 3-year calendar instead. The V6 has a timing belt (code 4), and all-wheel-drive models need rear differential fluid (code 6).

How the Minder works on a Passport
Oil life counts down from 100%. At 15% the display shows A (oil) or B (oil, filter, and inspections), plus the numbers of any other jobs due. If no message appears within 12 months of a reset, change the oil anyway; if code 7 doesn’t appear within 3 years, change the brake fluid anyway. The full code list: Honda Maintenance Minder codes. Honda’s system across all models: Honda maintenance.
Passport service items by generation
Items and conditions below are from Honda’s Passport manuals, in our words. The Minder decides the mileage for each code.

Reminder system: Honda Maintenance Minder.1 Oil changes: when the Maintenance Minder shows it, at least once a year.
| Service | When |
|---|---|
| Tire rotation | code 1 (Maintenance Minder)1 |

Codes that matter most on a Passport
- Code 3, transmission and transfer fluid. The 9-speed (2019–2025) and the 10-speed (2026) take different Honda fluids, ATF Type 3.1 and ATF type 2.0. Make sure the shop uses the one in your manual. See transmission fluid change.
- Code 4, timing belt. Spark plugs, a new timing belt, and a water pump inspection. Honda says to replace the belt every 60,000 miles in very hot or very cold climates; the 2026 manual adds towing to that list. More: timing belt replacement.
- Code 6, rear differential fluid. On all-wheel-drive models. In hard use, Honda wants it at 7,500 miles and then every 15,000 miles. See differential fluid.
- Code 7, brake fluid. At least every 3 years. See brake fluid flush.
What changed for 2026
The 2026 Minder table drops the valve clearance inspection from code 4, which the 2019–2020 manuals included. The new engine and 10-speed transmission also mean new fluids and filters, so a parts list for a 2022 Passport won’t carry over.
Normal or severe use?
The Minder already adjusts oil life for short trips, towing, and cold weather, so Honda prints no separate severe schedule. Your conditions still decide three things: the timing belt at 60,000 miles in temperature extremes, the rear differential fluid at 7,500 and then every 15,000 miles in hard use, and the air filter and dust and pollen filter every 15,000 miles on dusty roads or in heavy city soot. More: normal vs severe maintenance.
Keep the record
Each reset wipes the Minder’s memory. Write down the date, odometer, and code after each visit. A timing belt receipt is the first thing a buyer of a used Passport will ask to see. Oil details: Passport oil.
FAQ
What is code 7 on a Honda Passport?
Replace the brake fluid. If the code doesn’t appear within 3 years, change the fluid anyway.
Does the Honda Passport have a timing belt?
Yes. Code 4 calls for it, and Honda says to replace it every 60,000 miles in extreme heat or cold, and also when towing on the 2026.
How often does a Passport need transmission fluid?
When the Minder shows code 3. The manual gives no fixed mileage for normal use.
Does a Passport need rear differential fluid?
All-wheel-drive models do, on code 6. Front-wheel-drive models from 2019–2022 have no rear differential.
