## Diagnostic Tool Categories
### Code Retrieval vs System Analysis Tools
Basic code readers provide error identifiers like **P0171** or **C1234**, requiring external decoding. Professional tools like the Innova 5610 offer dynamic metrics including:
– Thermal sensor readings
– Combustion mixture balance

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **System Identifier**:
– **P** = Powertrain
– **C** = Chassis
2. **Standardization Level**:
– **0** = Generic code
– **1** = Brand-exclusive
3. **Component Group**:
– **3** = Ignition system

## Troubleshooting Protocol
1. **Symptom Verification**:
– Road test to confirm abnormalities
2. **DTC Extraction**:
– Connect diagnostic tool to vehicle interface
3. **System Condition Capture**:
– Examine vehicle vitals at error occurrence
4. **Part Verification**:
– Circuit analysis on sensors
