### Code Retrieval vs System Analysis Tools
Entry-level tools provide error identifiers like **P0171** or **C1234**, requiring manual interpretation. Advanced systems like the Innova 5610 offer live parameters including:
– Engine coolant temperature
– Combustion mixture balance

## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **System Identifier**:
– **P** = Engine/Transmission
– **C** = Chassis
2. **Code Type**:
– **0** = SAE standard
– **1** = Brand-exclusive
3. **Subsystem**:
– **3** = Ignition system

## Vehicle Analysis Procedure
1. **Initial Assessment**:
– Driving simulation to confirm abnormalities
2. **Code Retrieval**:
– Connect diagnostic tool to 16-pin port
3. **System Condition Capture**:
– Examine vehicle vitals at error occurrence
4. **Part Verification**:
– Multimeter checks on control modules
