What Does Honda B 123 Service Mean?

The Honda B 123 is a Maintenance Minder Code indicating your vehicle is due for certain regular maintenance activities. 

Here’s the breakdown: 

  • 1: Rotate tires, check tire pressure and condition
  • 2: Replace the air cleaner, cabin air filter, and inspect the drive belt

The Honda Motor Company uses this Maintenance Minder code on different models, including:

  • Honda Civic
  • Honda Accord
  • Honda CR V
  • Honda Odyssey

How to Fix a Honda B 123 Service Code?

1. Safeguard Your Engine with Fresh Oil and a New Oil Filter

You’ll get a maintenance minder warning when the oil life on your Honda Civic, Honda Accord, or another Honda model reaches 15%. 

Along with engine oil, also replace the oil filter so the engine gets an optimal supply of motor oil. A clogged oil filter can lead to engine overheating and damage.

2. Rotate Your Tires to Ensure their Longevity

Tire rotation helps attain even wear and tread depth, making them usable for longer. You should also routinely check the air pressure in the tires.

3. Replace Dirty Air Filters to Let Your Engine and Yourself Breathe Freely

Why are clean air filters important for your Honda vehicle?

  • Engine filter: A clogged air cleaner element restricts the amount of air your engine gets, leading to reduced engine performance and poor fuel economy.
  • Cabin filter: A bad cabin air filter can lead to reduced airflow and an unpleasant smell when using the heating or cooling system.

5. Check the Drive Belt to Avoid Unexpected Breakdowns

The drive belt transfers power from the engine to several components, like:

This makes it necessary to periodically inspect the drive belt for signs of wear.

6. Change Transmission Fluid to Shift Smoothly

Transmission fluid, like engine oil, gets contaminated over time, reducing its lubricating effectiveness. Change it when subcode 3 appears, and also change the transfer case fluid if your vehicle has a four-wheel drive system.

When to Get a Honda B123 Service?

You’ll get a dashboard warning message when you’re due for a Honda B123 service.
