5. Understanding Diagnostic Trouble Codes (DTCs)

Diagnostic Trouble Codes (DTCs) are codes stored by your car’s computer when it detects a problem. Understanding these codes is crucial for diagnosing and repairing your car.

5.1. Common DTC Categories

DTCs are typically categorized into four main groups:

• P Codes (Powertrain): These codes relate to the engine, transmission, and related components.
• B Codes (Body): These codes relate to the body control systems, such as power windows, door locks, and lighting.
• C Codes (Chassis): These codes relate to the chassis systems, such as ABS, traction control, and suspension.
• U Codes (Network): These codes relate to the communication network between different control modules in the car.

5.2. Interpreting DTCs

Each DTC consists of a five-character code that provides information about the problem. The first character indicates the category (P, B, C, or U). The second character indicates whether the code is generic (0) or manufacturer-specific (1). The remaining three characters provide specific information about the problem.

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

5.3. Clearing DTCs

Once you’ve identified and repaired the problem, you can clear the DTC using your OBD2 scanner. However, it’s important to note that clearing the code will not fix the underlying issue. The code will likely return if the problem persists.

6. Advanced Diagnostic Functions

In addition to reading and clearing DTCs, some iPhone OBD2 Bluetooth scanners offer advanced diagnostic functions.
