What is the service code B-1-2 on a Honda?
B-1-2 is a Honda Maintenance Minder code signaling a B‑level service with two tasks included in the scheduled maintenance. The exact tasks depend on your model year and trim, so check your owner's manual or ask your dealer for the precise list.
What the code means in Honda's maintenance system
Honda’s Maintenance Minder uses letters to denote broad service levels (A or B) and numbers to indicate sub-tasks within that level. A service at level B typically covers more items than the basic A service, and the additional 1 and 2 identify two specific tasks chosen for your vehicle’s interval. Because Honda tailors maintenance recommendations to each model-year and driving conditions, the B‑1‑2 mapping can vary from car to car.
How it is applied in practice
When your vehicle is due for service, the dealership or repair shop translates B‑1‑2 into a concrete set of tasks shown on the maintenance worksheet or the car’s maintenance minder display. To know exactly what B‑1‑2 means for your Honda, consult the owner’s manual section on Maintenance Minder or have your dealer pull up the vehicle-specific service mapping for your VIN.
Before listing typical elements that might appear under a B‑1‑2 service, note that actual items can differ by model and year.
Common elements you might see included in B‑1‑2 (these can vary by model):
- Engine oil and oil filter replacement
- Tire rotation
- Brake system inspection and fluid level checks
- Inspection (and possible replacement) of engine air filter
- Inspection (and possible replacement) of cabin air filter
- Checks of key fluids (coolant, brake fluid, windshield washer fluid) and accessory belts or hoses
Because the exact tasks associated with B‑1‑2 vary by model year and trim, rely on your service sheet or the owner’s manual for specifics, and ask the technician to explain each item if anything is unclear.
What to do if you see B-1-2 on your Honda
First, confirm with your service advisor which tasks the B‑1‑2 code corresponds to for your exact vehicle. If you’re reviewing a maintenance history or a printed invoice, request a copy of the task list mapped to B‑1‑2. This helps you understand what was done and plan for future maintenance intervals.
Summary
B-1-2 is not a fault code; it is part of Honda’s Maintenance Minder system indicating a B‑level service with two chosen tasks. The precise items included under B‑1‑2 depend on the model year, trim, and driving conditions, so always verify the exact tasks in the owner’s manual or with your dealer, and use the service sheet to track what was performed.
