## Diagnostic Tool Categories
### Code Retrieval vs System Analysis Tools
Entry-level tools provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring additional research. Professional tools like the Ancel BD310 offer real-time data including:
– Thermal sensor readings
– Air-fuel ratio

## Error Code Composition
Each 5-character code follows this pattern:
1. **System Identifier**:
– **P** = Powertrain
– **C** = Undercarriage
2. **Code Type**:
– **0** = Generic code
– **1** = Manufacturer-specific
3. **Subsystem**:
– **3** = Spark components

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Operational evaluation to confirm abnormalities
2. **DTC Extraction**:
– Connect code reader to 16-pin port
3. **System Condition Capture**:
– Examine vehicle vitals at time of fault
4. **Component Testing**:
– Circuit analysis on actuators
