## OBD-II Scanner Types
### Code Retrieval vs System Analysis Tools
Basic code readers provide error identifiers like **P0171** or **C1234**, requiring manual interpretation. Advanced systems like the Innova 5610 offer live parameters including:
– Coolant heat levels
– Combustion mixture balance

## DTC Format Breakdown
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Engine/Transmission
– **C** = Undercarriage
2. **Code Type**:
– **0** = Universal definition
– **1** = Brand-exclusive
3. **Component Group**:
– **3** = Combustion electronics
