Honda Maintenance Minder gets more interesting once you get past A1 and B16.
Take code 4.
It doesn't automatically mean the exact same service on every Honda.
On a current CR-V, Honda uses code 4 for spark plugs and valve-clearance inspection.
On a current Pilot, that same code also includes timing-belt replacement and water-pump inspection.
That's a pretty big difference under the same number.
Codes 3, 5, 6 and 7 have their own vehicle-specific details too.
And Honda's B service is more than an oil change. It includes oil and filter service plus a broader inspection of areas such as the brakes, steering, suspension, fluids and other systems.
The good news?
You don't have to figure any of that out before calling us.
Tell us the code showing on your dash.
We'll check your exact year and model, review what Honda calls for and explain what actually applies.
