7.4. Handle with Care

Avoid dropping or mishandling the scanner, as this can damage the internal components.

8. Understanding Diagnostic Trouble Codes (DTCs)

Diagnostic Trouble Codes (DTCs) are codes stored in your vehicle’s computer that indicate a specific problem. These codes are standardized across the automotive industry, making it easier to diagnose and repair issues.

8.1. Types of DTCs

DTCs are typically composed of a letter followed by four numbers. The letter indicates the system where the fault occurred:

• P: Powertrain (engine and transmission)
• B: Body (interior and exterior components)
• C: Chassis (braking, suspension, and steering)
• U: Network (communication systems)

The first number indicates whether the code is generic (0) or manufacturer-specific (1). The remaining three numbers provide more specific information about the fault.

8.2. Common DTC Examples

• P0300: Random/Multiple Cylinder Misfire Detected
• P0171: System Too Lean (Bank 1)
• P0420: Catalyst System Efficiency Below Threshold (Bank 1)
• P0101: Mass Air Flow Circuit Range/Performance Problem

8.3. Finding DTC Definitions

You can find definitions for DTCs using your OBD2 app, online OBD2 code databases, or repair manuals. Understanding the definition of a DTC is the first step in diagnosing and repairing the underlying issue.
