## Diagnostic Tool Categories
### Code Retrieval vs System Analysis Tools
Entry-level tools provide error identifiers like **P0171** or **C1234**, requiring manual interpretation. Professional tools like the Innova 5610 offer live parameters including:
– Coolant heat levels
– Combustion mixture balance

## DTC Format Breakdown
Each 5-character code follows this pattern:
1. **System Identifier**:
– **P** = Powertrain
– **C** = Undercarriage
2. **Standardization Level**:
– **0** = Universal definition
– **1** = OEM-defined
3. **Subsystem**:
– **3** = Spark components

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Road test to verify symptoms
2. **Code Retrieval**:
– Connect code reader to 16-pin port
3. **Freeze Frame Analysis**:
– Examine engine parameters at error occurrence
4. **System Validation**:
– Circuit analysis on control modules
