## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **System Identifier**:
– **P** = Drivetrain
– **C** = Suspension/Brakes
2. **Manufacturer Specification**:
– **0** = Generic code
– **1** = Brand-exclusive
3. **Component Group**:
– **3** = Combustion electronics

## Diagnostic Process Steps
1. **Symptom Verification**:
– Road test to confirm abnormalities
2. **Code Retrieval**:
– Connect OBD-II scanner to 16-pin port
3. **Freeze Frame Analysis**:
– Examine engine parameters at code triggering
4. **Component Testing**:
– Electrical measurements on sensors
