## Diagnostic Tool Categories
### Display vs. Diagnostic Scanners
Display scanners provide error identifiers like **P0171** or **C1234**, requiring additional research. Advanced systems like the BlueDriver Pro offer real-time data including:
– Engine coolant temperature
– Air-fuel ratio

## DTC Format Breakdown
Each 5-character code follows this pattern:
1. **Module Designator**:
– **P** = Engine/Transmission
– **C** = Undercarriage
2. **Standardization Level**:
– **0** = Universal definition
– **1** = Manufacturer-specific
3. **Component Group**:
– **3** = Spark components
