5. Read Data: Once connected, you can read real-time data, check for DTCs, and perform other diagnostic functions.

5. Understanding OBD-II Codes

OBD-II codes, also known as Diagnostic Trouble Codes (DTCs), are codes that your car’s computer generates when it detects a problem. Understanding these codes is essential for diagnosing and repairing your vehicle.

5.1 Common OBD-II Code Categories

• P (Powertrain): Relates to the engine, transmission, and associated components.
• B (Body): Relates to body-related functions like airbags, power windows, and central locking.
• C (Chassis): Relates to chassis components like ABS, traction control, and suspension.
• U (Network): Relates to the vehicle’s communication network.

5.2 Decoding DTCs

Each DTC consists of five characters: one letter followed by four numbers. The letter indicates the system (P, B, C, or U), the first number indicates whether the code is generic (0) or manufacturer-specific (1, 2, or 3), and the remaining numbers provide more specific information about the fault.

For example, a code like P0300 indicates a random or multiple cylinder misfire in the engine.

5.3 Clearing Codes

Once you have identified and repaired the issue, you can use the ELM327 software to clear the DTCs. Keep in mind that clearing codes does not fix the problem; it only turns off the check engine light.
