## Diagnostic Tool Categories
### Code Retrieval vs System Analysis Tools
Display scanners provide fault codes like **P0171** or **C1234**, requiring manual interpretation. Diagnostic scanners like the Innova 5610 offer live parameters including:
– Engine coolant temperature
– Combustion mixture balance

## Error Code Composition
Each 5-character code follows this pattern:
1. **System Identifier**:
– **P** = Drivetrain
– **C** = Undercarriage
2. **Standardization Level**:
– **0** = Generic code
– **1** = Manufacturer-specific
3. **Component Group**:
– **3** = Combustion electronics

## Diagnostic Process Steps
1. **Symptom Verification**:
– Operational evaluation to verify symptoms
2. **Code Retrieval**:
– Connect OBD-II scanner to 16-pin port
3. **System Condition Capture**:
– Examine vehicle vitals at time of fault
4. **Component Testing**:
– Circuit analysis on actuators
