## OBD-II Scanner Types
### Basic vs. Advanced Readers
Basic code readers provide error identifiers like **P0171** or **C1234**, requiring external decoding. Diagnostic scanners like the Ancel BD310 offer dynamic metrics including:
– Thermal sensor readings
– Fuel trim values

## Diagnostic Trouble Code Structure
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Powertrain
– **C** = Chassis
2. **Manufacturer Specification**:
– **0** = Generic code
– **1** = OEM-defined
3. **Functional Area**:
– **3** = Ignition system
