What Do the Letters on Your Honda or Acura Service Light Mean?
If you're driving a Honda or Acura and suddenly see a service light with letters like A, B, or 1–7, don't panic! These codes are part of your vehicle's Maintenance Minder System—a smart reminder that your vehicle needs attention. At McGrath Acura of Libertyville, we help customers across Libertyville, Vernon Hills, Highland Park, and more understand these alerts and keep their vehicles running at peak performance.
Understanding Honda & Acura Maintenance Minder Codes
When your Maintenance Minder activates, you'll see either an A or B code followed by one or more numbered sub-codes (1–7). Here's what they all mean:
Main Service Codes
- A – Replace engine oil only
- B – Replace engine oil and oil filter; inspect brakes, fluid levels, tire condition and pressure, suspension, and more
Sub-Service Codes
- 1 – Rotate tires
- 2 – Replace air cleaner element, inspect drive belt, replace dust and pollen filter
- 3 – Replace transmission fluid
- 4 – Replace spark plugs and timing belt (if applicable); inspect water pump
- 5 – Replace engine coolant
- 6 – Replace rear differential fluid (for AWD models)
- 7 – Brake fluid replacement
Why the Maintenance Minder Matters
Ignoring these codes can lead to bigger, more expensive problems down the road. Whether it's a simple oil change (Code A) or a transmission service (Code 3), timely service:
- Extends vehicle life
- Maximizes performance
- Maintains fuel efficiency
- Protects your investment
