Honda B123 Service Code: Checlist & Maintenance Cost

It is my intention in this article to describe the Honda B123 Service and how it can benefit you. You’ll know how to reset the code and what elements are included.

Honda is one of my favorite automobile manufacturers, because of its proven reliability record. For Hondas to perform at their best, they must also be serviced regularly.

What is the B123 Service code in Honda?

Honda B123 Service

A Honda B123 Service code is a maintenance minder that alerts you when you need to have your Honda serviced. Those letters stand for: 

  • B = Replacement of engine oil
  • 1 = Rotation of tires
  • 2 = Cabin and air filter replacement
  • 3 = Replacement of transmission fluid

With Maintenance Minder, you can see what problems are surfacing on the dashboard and get alerts. Tracking your car’s performance is the best way to determine where improvements can be made. 

What items are included in the Honda B123 Service?

You should now have a better understanding of what that code means after reading the above content. When you bring your Honda vehicle in for the B123 Service, you can expect to receive the following services. 

Engine Oil Change

Honda vehicles require a lot of engine oil, which is considered one of the most important fluids. By keeping the motor clean and lubricated, its durability can be extended. 

An oil change should be performed at least once a year or every 5,000 to 7,500 miles according to most experts. In addition, it is a good idea to follow the vehicle’s manufacturer’s recommendations. 

Tire Rotation or sub-code 1

Another important part of the service is rotation of the tires. 

It is important to maintain the tires in order to extend their lifespan and capability. 

If you don’t rotate your tires when they need to be rotated, your rims can become bent. As a result of all these valid reasons, it’s part of a number of important services that can affect Honda’s overall performance. 

In other words, it is recommended that you rotate the tires every 5,000 to 7,500 miles (on both front and rear wheels). 

Air Filter Change

Air filters are essential to the operation of your Honda engine. Among its functions is to filter, and insects, dust particles, and debris are allowed to enter the engine through that filter.

Having a full filter will result in high fuel consumption if it is not functioning correctly. 

It is recommended to change the air filter every 15,000 to 30,000 miles or once a year, however, this may vary depending on the vehicle and driving habits.

Cabin Filter Change

A cabin filter prevents dust and debris from entering your car’s cabin (like an air filter). As a result, both elements are essential to the operation of a filtering system. 

It is recommended to replace the cabin filter between 15,000 and 30,000 miles. 

Transmission Fluid Replacement

As part of the B123 Service code, the last maintenance is replacing the transmission fluid. This fluid protects the transmission from damage and keeps it cool. 

An untimely breakdown can be caused by dirty transmission fluid. It is possible for these breakdowns to cause problems with the clutches and brake bands, which can cause serious problems.

As a result, transmission fluid replacements are divided into two categories:

  1. 30,000-60000 miles on the drive manual.
  2. 60,000 to 100,000 miles for automatics.

It is recommended by most manufacturers that these values be used, but these values can also change. It is fine to replace your fluid early; however, late replacement can have adverse effects.
