## OBD-II Scanner Types
### Basic vs. Advanced Readers
Entry-level tools provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring additional research. Professional tools like the BlueDriver Pro offer dynamic metrics including:
– Thermal sensor readings
– Fuel trim values

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **Component Category**:
– **P** = Drivetrain
– **C** = Chassis
2. **Code Type**:
– **0** = Universal definition
– **1** = Manufacturer-specific
3. **Functional Area**:
– **3** = Spark components

## Vehicle Analysis Procedure
1. **Initial Assessment**:
– Driving simulation to confirm abnormalities
2. **DTC Extraction**:
– Connect diagnostic tool to DLC connector
3. **System Condition Capture**:
– Examine engine parameters at error occurrence
4. **Component Testing**:
– Electrical measurements on sensors
