## Diagnostic Tool Categories
### Code Retrieval vs System Analysis Tools
Display scanners provide error identifiers like **P0171** or **C1234**, requiring external decoding. Professional tools 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. **Module Designator**:
– **P** = Drivetrain
– **C** = Chassis
2. **Code Type**:
– **0** = Universal definition
– **1** = OEM-defined
3. **Subsystem**:
– **3** = Combustion electronics

## Vehicle Analysis Procedure
1. **Initial Assessment**:
– Operational evaluation to verify symptoms
2. **DTC Extraction**:
– Connect diagnostic tool to DLC connector
3. **Snapshot Data Review**:
– Examine operational metrics at code triggering
4. **System Validation**:
– Multimeter checks on control modules
