The A137 Honda maintenance code represents an oil change, tire rotation service, engine, and cabin air filter replacement, drive belt inspection, and brake fluid replacement.
The “A” stands for an oil change, the “1” stands for a tire rotation, the”3″ stands for a transmission fluid replacement and transfer fluid replacement, and the “7” stands for brake fluid replacement.
The A137 service is similar to the A13 service but it adds but adds brake fluid replacement. It is typically performed by a Honda dealership or with a local mechanic but it can also be performed at home without needing special tools.

“A” Service Cost
The “A” service, or oil change, typically costs $50 to $100 depending on the Honda model you have. It is a 30 to 40-minute service with the cost mostly from the parts. Some Honda vehicles, like the 2022 Pilot, require synthetic oil which is more expensive.

A137 Maintenance Minder Description
The Honda maintenance minder code sheet above lists all the main and sub service items with A137 highlighted.
“A” Main Service Item
Honda describes the “A” service as an engine oil change only. Although it recommends oil change only, it is best practice to replace the oil filter whenever the oil is changed.
“1” Sub Service Item
Honda describes the “1” service as a tire rotation. In addition to rotating the tires, dealerships will also check the tire pressure and treads for wear or punctures.
“3” Sub Service Item
Honda describes the “3” service as a transmission fluid replacement and transfer case fluid replacement. Only Hondas with 4WD or AWD will have a transfer case and need the fluid changed out.
“7” Sub Service Item
Honda describes the “7” service as a brake fluid replacement where all the brake fluid is flushed out of the vehicle hydraulic brake system.
When Is the Honda A137 Service Due?
The Maintenance Minder displays A137 when remaining oil life drops to 15%, which for most drivers falls between 5,000 and 7,500 miles after the last oil service — sooner with heavy city driving, towing or lots of short trips, later with steady highway use. Because the system reads actual operating conditions rather than counting miles, the exact figure differs from car to car.
The sub-items attached to this code run on their own longer intervals:
- 1 — Tire rotation: Every oil service
- 3 — Transmission fluid + transfer case fluid (if equipped): ~90,000 mi
- 7 — Brake fluid replacement: Every 3 years
That is why the code changes over time: an A1 becomes A137 once those additional items fall due in the same visit.
Honda Models That Show the A137 Code
The A137 code can appear on any Maintenance Minder–equipped Honda, including the Honda Accord, Honda Civic, Honda CR-V, Honda Pilot, Honda Odyssey, Honda HR-V, Honda Passport, Honda Ridgeline and Honda Insight. The services it calls for are identical across the range, but oil capacity, fluid specification and labor time vary by engine — and AWD or SH-AWD models add transfer case fluid to sub-item 3. Always confirm the specification your engine requires in the owner’s manual.

Brake Fluid: The One Part of A137 That Ignores Your Mileage
Sub-item 7 is a brake fluid replacement, and it is the odd one out in A137 because it runs on a calendar rather than an odometer. Honda calls for brake fluid every three years regardless of mileage. A car that covers 4,000 miles a year needs it on exactly the same schedule as one covering 20,000.
The reason is that brake fluid is hygroscopic: it absorbs moisture from the air through the hoses and reservoir over time. Water lowers the boiling point, and fluid that boils under hard or sustained braking turns to vapor, which compresses. That is the long, soft pedal people describe coming down a mountain pass. It is also why the service is not optional on a low-mileage car.
Honda specifies DOT 3, and the job is a proper bleed at all four corners until clean fluid runs through, not a reservoir top-up. Old fluid is visibly darker than new. If a shop quotes A137 and the price looks light, it is worth confirming the brake fluid line is actually a flush.
Where this sits in A137: the “A” is a plain oil change, sub-items 1 and 3 add the tire rotation, the transmission fluid, and sub-item 7 is the item described above. Each is tracked separately by the Maintenance Minder, so A137 is a bundle of independent jobs that happened to come due together, not one procedure with a single price.
Honda A137 Service FAQ
What does the Honda A137 code actually include?
Reading it left to right: the “A” is an oil change, and each number after it is a separate job. For A137 that means a tire rotation, a transmission fluid change, a brake fluid replacement. They arrive together because the Maintenance Minder counts each item down on its own schedule and shows you whatever has come due at the same time, which is why the same car shows different combinations at different points in its life.
How long can I leave the A137 service?
The oil portion is what has a real deadline. The wrench appears at 15% oil life, sharpens at 5%, and at 0% the display starts counting how far overdue you are. The brake fluid in A137 is the item people wrongly treat as flexible: it is on a three-year clock and a low-mileage car is not exempt.
Can I do the Honda A137 service myself?
Partly, and it is worth splitting the job. The oil and the tire rotation are straightforward at home. The remaining fluid work needs the right Honda-specific fluid rather than a universal equivalent.
Is the A137 service covered by Honda Service Pass?
No. Honda Service Pass covers the basic A1 and B1 services — oil, filter, tire rotation and inspection — on 2025 and newer Hondas for one year or 12,000 miles. A137 includes work beyond that scope, so the extra items are chargeable even on a car still inside the term. Ask for an itemized invoice: the oil and rotation portion may still be covered while the rest is not.
Does A137 mean something is wrong with my Honda?
No. It is the maintenance schedule, not the diagnostics. A137 shows as a wrench symbol and simply means the algorithm has counted those items down to zero. A check engine light is a different system reporting a stored fault. If both are lit they are unrelated, and the check engine light is the one to investigate first.
How do I reset the A137 code?
Touchscreen cars: Settings, then Vehicle, then Maintenance Reset. Older models: hold the SEL/RESET button or trip stalk for around ten seconds with the ignition on. Reset only the items actually done — on multi-item codes like A137 you can reset individual sub-items, and clearing the whole code after doing only the oil will hide the jobs you still owe the car. Our Honda Maintenance Minder reset guide covers it model by model.
