## OBD-II Scanner Types
### Display vs. Diagnostic Scanners
Display scanners provide fault codes like **P0171** or **C1234**, requiring additional research. Advanced systems like the Innova 5610 offer real-time data including:
– Thermal sensor readings
– Air-fuel ratio

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Powertrain
– **C** = Chassis
2. **Code Type**:
– **0** = Generic code
– **1** = Brand-exclusive
3. **Functional Area**:
– **3** = Combustion electronics

## Troubleshooting Protocol
1. **Initial Assessment**:
– Operational evaluation to confirm abnormalities
2. **System Interrogation**:
– Connect code reader to vehicle interface
3. **Snapshot Data Review**:
– Examine operational metrics at code triggering
4. **System Validation**:
– Electrical measurements on actuators
