## Diagnostic Tool Categories
### Display vs. Diagnostic Scanners
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring manual interpretation. Professional tools like the Ancel BD310 offer live parameters including:
– Engine coolant temperature
– Air-fuel ratio

## Error Code Composition
Standard alphanumeric identifiers follows this pattern:
1. **System Identifier**:
– **P** = Engine/Transmission
– **C** = Suspension/Brakes
2. **Manufacturer Specification**:
– **0** = Generic code
– **1** = Manufacturer-specific
3. **Subsystem**:
– **3** = Spark components

## Troubleshooting Protocol
1. **Problem Confirmation**:
– Road test to verify symptoms
2. **Code Retrieval**:
– Connect code reader to DLC connector
3. **Freeze Frame Analysis**:
– Examine engine parameters at code triggering
4. **System Validation**:
– Circuit analysis on actuators
