What Do Acura Service Codes Mean?

As an Acura vehicle owner in Katy, it’s important for you to have a basic understanding of Acura service codes. These codes are broken down into two sections: the main code and a subcode. These codes work together to help you understand what it is your vehicle is trying to tell you. Learn more about Acura service codes and Acura maintenance codes below from John Eagle Acura.

Main Codes

There are two types of main codes for Acura models: A or B. So what is the difference between Acura service code A and Acura service code B? If the code begins with an A, it means the engine oil needs to be replaced. If the code begins with a B, it could mean a variety of things:

  • Replace engine oil
  • Replace engine oil filter
  • Inspect front or rear brakes
  • Check parking brake adjustment
  • Check tire repair kit expiration date
  • Inspect tire rods
  • Inspect steering gearbox
  • Inspect suspension components
  • Inspect brake hoses
  • Inspect fluid levels
  • Inspect exhaust system

Sub Codes

In addition to the main code, the Acura sub codes will help you find out more information about the issue. These subcodes are all broken down by a number, so you could receive Acura service codes b1, Acura service codes A1, or others.

  • 1 – Indicates tires need to be rotated
  • 2 – Requires air cleaner element; dust/pollen filter to be replaced; and drive belt to be inspected
  • 3 – Transmission fluid should be replaced
  • 4 – Indicates spark plugs and timing belt should be replaced; valve and water pump should be inspected
  • 5 – Engine coolant should be replaced
  • 6 – Rear differential fluid should be replaced
