## OBD-II Scanner Types
### Basic vs. Advanced Readers
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring additional research. Diagnostic scanners like the Ancel BD310 offer real-time data including:
– Thermal sensor readings
– Fuel trim values

## Error Code Composition
Standard alphanumeric identifiers follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Suspension/Brakes
2. **Manufacturer Specification**:
– **0** = Universal definition
– **1** = OEM-defined
3. **Functional Area**:
– **3** = Spark components

## Vehicle Analysis Procedure
1. **Problem Confirmation**:
– Driving simulation to confirm abnormalities
2. **DTC Extraction**:
– Connect diagnostic tool to 16-pin port
3. **Snapshot Data Review**:
– Examine operational metrics at error occurrence
4. **System Validation**:
– Electrical measurements on sensors
