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

## Error Code Composition
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Powertrain
– **C** = Chassis
2. **Manufacturer Specification**:
– **0** = SAE standard
– **1** = Brand-exclusive
3. **Component Group**:
– **3** = Combustion electronics
—
## Troubleshooting Protocol
1. **Initial Assessment**:
– Driving simulation to confirm abnormalities
2. **Code Retrieval**:
– Connect code reader to DLC connector
3. **Snapshot Data Review**:
– Examine engine parameters at time of fault
4. **Part Verification**:
– Circuit analysis on control modules
