  5. View the Codes: The app will display any stored diagnostic trouble codes (DTCs). These codes are usually in the format of a letter followed by four numbers (e.g., P0300).

3.2. Understanding Common OBD2 Code Categories

OBD2 codes are categorized by the first letter of the code, indicating the system the code refers to:

  • P (Powertrain): These codes relate to the engine, transmission, and associated components.
  • B (Body): These codes pertain to the body of the vehicle, including systems like airbags, power windows, and seats.
  • C (Chassis): These codes relate to the chassis, including the braking system, suspension, and steering.
  • U (Network): These codes refer to the vehicle’s communication network.

Each code provides specific information about the issue. For example, a P0300 code indicates a random or multiple cylinder misfire.

3.3. Using Online Resources to Interpret Specific Codes

Once you have the OBD2 codes, you can use online resources to understand their meaning. Some reliable resources include:

  • OBD2-SCANNER.EDU.VN: Offers a comprehensive database of OBD2 codes and their descriptions.
