## Vehicle Code Readers
### Code Retrieval vs System Analysis Tools
Basic code readers provide fault codes like **P0171** or **C1234**, requiring manual interpretation. Professional tools like the Ancel BD310 offer real-time data including:
– Thermal sensor readings
– Air-fuel ratio

## Error Code Composition
Vehicle-specific fault markers follows this pattern:
1. **System Identifier**:
– **P** = Powertrain
– **C** = Undercarriage
2. **Manufacturer Specification**:
– **0** = Generic code
– **1** = OEM-defined
3. **Component Group**:
– **3** = Ignition system
—
## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Operational evaluation to replicate issues
2. **Code Retrieval**:
– Connect code reader to DLC connector
3. **Snapshot Data Review**:
– Examine operational metrics at error occurrence
4. **Part Verification**:
– Circuit analysis on control modules
