## OBD-II Scanner Types
### Code Retrieval vs System Analysis Tools
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring additional research. Advanced systems like the Innova 5610 offer real-time data including:
– Engine coolant temperature
– Air-fuel ratio

## DTC Format Breakdown
Standard alphanumeric identifiers follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Chassis
2. **Standardization Level**:
– **0** = SAE standard
– **1** = OEM-defined
3. **Component Group**:
– **3** = Spark components

## Troubleshooting Protocol
1. **Problem Confirmation**:
– Operational evaluation to replicate issues
2. **Code Retrieval**:
– Connect diagnostic tool to vehicle interface
3. **Freeze Frame Analysis**:
– Examine vehicle vitals at time of fault
4. **Component Testing**:
– Electrical measurements on actuators
