## OBD-II Scanner Types
### Basic vs. Advanced Readers
Display scanners provide fault codes like **P0171** or **C1234**, requiring manual interpretation. Advanced systems like the Innova 5610 offer live parameters including:
– Thermal sensor readings
– Air-fuel ratio

## Diagnostic Trouble Code Structure
Each 5-character code follows this pattern:
1. **Module Designator**:
– **P** = Engine/Transmission
– **C** = Chassis
2. **Code Type**:
– **0** = Universal definition
– **1** = Brand-exclusive
3. **Subsystem**:
– **3** = Combustion electronics
