## Diagnostic Tool Categories
### Code Retrieval vs System Analysis Tools
Entry-level tools provide fault codes like **P0171** or **C1234**, requiring external decoding. Advanced systems like the Innova 5610 offer dynamic metrics including:
– Engine coolant temperature
– Air-fuel ratio

## DTC Format Breakdown
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Engine/Transmission
– **C** = Suspension/Brakes
2. **Code Type**:
– **0** = Generic code
– **1** = Manufacturer-specific
3. **Subsystem**:
– **3** = Spark components

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Driving simulation to confirm abnormalities
2. **DTC Extraction**:
– Connect diagnostic tool to 16-pin port
3. **Snapshot Data Review**:
– Examine operational metrics at code triggering
4. **Part Verification**:
– Circuit analysis on sensors
