The Honda Maintenance Minder™ System will indicate the necessary maintenance items for your vehicle based on driving conditions rather than mileage. It will display a code such as A1, B13, and so on indicating what service is recommended. The recommended maintenance per Honda is once per year or when the yellow wrench light and service codes display, whichever comes first.
Below is an example from a 2018 Honda CR-V owner's manual showing what the Maintenance Minder ™ code indicates. Please consult the owner's manual for your vehicle for model-specific details since certain models have special requirements.
