## OBD-II Scanner Types
### Code Retrieval vs System Analysis Tools
Basic code readers provide fault codes like **P0171** or **C1234**, requiring manual interpretation. Diagnostic scanners like the Innova 5610 offer dynamic metrics including:
– Engine coolant temperature
– Air-fuel ratio

## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **System Identifier**:
– **P** = Engine/Transmission
– **C** = Suspension/Brakes
2. **Manufacturer Specification**:
– **0** = Universal definition
– **1** = Brand-exclusive
3. **Subsystem**:
– **3** = Spark components
