Acura Maintenance Minder Codes Explained

Acura Maintenance Minder codes are designed to take the guesswork out of vehicle upkeep. Rather than relying on a fixed mileage schedule, the Maintenance Minder system uses real-time driving data to determine exactly when vehicles manufactured in 2007 or later are due for service. Understanding what these codes mean will help you stay on top of maintenance and keep your Acura running at its best on every Montclair and Clifton drive.

Acura Maintenance Minder Codes Explained: Main Codes A & B

Every Maintenance Minder alert begins with a Main Code—either A or B—that indicates the general type of service your vehicle requires.

• Main Code A: It is time to replace your engine oil. This is the more straightforward of the two codes and typically requires a shorter visit to our Acura service center in Verona, NJ.
• Main Code B: A more comprehensive inspection, Main Code B includes an oil and filter change and a check of your brakes, suspension components, driveshaft boots, brake hoses and lines, fluid levels, exhaust system, and fuel lines and connections.

Acura Maintenance Sub-Codes 1–7: Meanings

Following the Main Code, you may see one or more numbers. These Sub-Codes identify additional services that are due at the same time. Take a look at the Acura maintenance Sub-Codes 1–7 and their meanings:

• Sub-Code 1: Rotate tires
• Sub-Code 2: Replace the air cleaner element, replace the dust and pollen filter, and inspect the drive belt
• Sub-Code 3: Replace transmission and transfer fluid
• Sub-Code 4: Replace spark plugs, replace timing belt, inspect water pump, and inspect valve opening
• Sub-Code 5: Replace engine coolant
• Sub-Code 6: Replace rear differential fluid (if equipped)
• Sub-Code 7: Replace brake fluid

Multiple Sub-Codes can appear together in a single alert, so a code like B15 would mean that a tire rotation and engine coolant replacement are needed.

Acura Service Code A1 Vs. B1

Two of the most common codes Acura owners encounter are A1 and B1, and it is helpful to understand how they differ. Here is a quick Acura service code A1 vs. B1 comparison:

• Code A1 means your vehicle is due for an engine oil replacement and a tire rotation. It is a relatively quick and routine visit.
• Code B1 includes those same items—oil and filter replacement and tire rotation—but adds a full mechanical inspection covering brakes, suspension, fluid levels, and more.

In short, B1 is the more involved appointment. If you see either code on your dashboard, scheduling service promptly will help protect your vehicle’s long-term reliability and performance on Bloomfield roads and beyond.
