## OBD-II Scanner Types
### Code Retrieval vs System Analysis Tools
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring manual interpretation. Professional tools like the Ancel BD310 offer real-time data including:
– Engine coolant temperature
– Combustion mixture balance

## Error Code Composition
Each 5-character code follows this pattern:
1. **System Identifier**:
– **P** = Powertrain
– **C** = Undercarriage
2. **Standardization Level**:
– **0** = Generic code
– **1** = OEM-defined
3. **Subsystem**:
– **3** = Ignition system

## Vehicle Analysis Procedure
1. **Initial Assessment**:
– Operational evaluation to verify symptoms
2. **DTC Extraction**:
– Connect code reader to vehicle interface
3. **System Condition Capture**:
– Examine engine parameters at code triggering
4. **Part Verification**:
– Circuit analysis on actuators
