Understanding the Different Types of Automotive Diagnostic Codes

Automotive diagnostic codes (and by using the best car scanner) are used to identify and diagnose problems with a vehicle’s engine, transmission, or other components. These codes can be divided into two main categories: generic and manufacturer-specific.

  • Generic codes are the most common type of diagnostic code and are used by all vehicles regardless of make or model. They provide a general description of the problem, such as “engine misfire” or “transmission slipping.” Generic codes can be read by any scan tool that is compatible with the vehicle’s onboard diagnostics system (OBD).
  • Manufacturer-specific codes are specific to each make and model of vehicle. These codes provide more detailed information about the problem than generic codes do, such as which component is malfunctioning or what part needs to be replaced. Manufacturer-specific codes must be read using a scan tool that is compatible with the particular make and model of the vehicle being diagnosed.
  • In addition to these two types of diagnostic code, there may also be additional manufacturer-specific trouble code definitions for certain makes and models that require special tools for diagnosis. For example, some European vehicles require an advanced scan tool to access their manufacturer-specific trouble code definitions.

Understanding the different types of automotive diagnostic codes is essential for accurately diagnosing problems with a vehicle’s engine or other components. Knowing which type of code applies to your particular make and model will help you determine what kind of scan tool you need to properly diagnose any issues your car may have.
