## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **System Identifier**:
– **P** = Engine/Transmission
– **C** = Suspension/Brakes
2. **Standardization Level**:
– **0** = SAE standard
– **1** = Manufacturer-specific
3. **Functional Area**:
– **3** = Combustion electronics
