## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **Component Category**:
– **P** = Powertrain
– **C** = Suspension/Brakes
2. **Standardization Level**:
– **0** = Universal definition
– **1** = Manufacturer-specific
3. **Functional Area**:
– **3** = Combustion electronics

## Diagnostic Process Steps
1. **Problem Confirmation**:
– Driving simulation to verify symptoms
2. **Code Retrieval**:
– Connect OBD-II scanner to DLC connector
3. **Freeze Frame Analysis**:
– Examine engine parameters at time of fault
4. **System Validation**:
– Circuit analysis on sensors
