## Diagnostic Tool Categories
### Code Retrieval vs System Analysis Tools
Basic code readers provide fault codes like **P0171** or **C1234**, requiring external decoding. Professional tools like the Ancel BD310 offer live parameters including:
– Engine coolant temperature
– Air-fuel ratio

## Error Code Composition
Vehicle-specific fault markers follows this pattern:
1. **Component Category**:
– **P** = Engine/Transmission
– **C** = Undercarriage
2. **Manufacturer Specification**:
– **0** = Generic code
– **1** = Brand-exclusive
3. **Subsystem**:
– **3** = Combustion electronics

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Road test to replicate issues
2. **Code Retrieval**:
– Connect diagnostic tool to vehicle interface
3. **Snapshot Data Review**:
– Examine operational metrics at code triggering
4. **System Validation**:
– Multimeter checks on sensors
