## Diagnostic Tool Categories
### Display vs. Diagnostic Scanners
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring manual interpretation. Advanced systems like the Innova 5610 offer live parameters including:
– Thermal sensor readings
– Combustion mixture balance

## Error Code Composition
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Engine/Transmission
– **C** = Suspension/Brakes
2. **Manufacturer Specification**:
– **0** = Universal definition
– **1** = Manufacturer-specific
3. **Subsystem**:
– **3** = Spark components
—
## Troubleshooting Protocol
1. **Initial Assessment**:
– Driving simulation to confirm abnormalities
2. **System Interrogation**:
– Connect code reader to vehicle interface
3. **Freeze Frame Analysis**:
– Examine vehicle vitals at code triggering
4. **Component Testing**:
– Electrical measurements on sensors
