## Error Code Composition
Vehicle-specific fault markers follows this pattern:
1. **Component Category**:
– **P** = Engine/Transmission
– **C** = Chassis
2. **Standardization Level**:
– **0** = Generic code
– **1** = OEM-defined
3. **Functional Area**:
– **3** = Combustion electronics

## Troubleshooting Protocol
1. **Initial Assessment**:
– Operational evaluation to confirm abnormalities
2. **System Interrogation**:
– Connect OBD-II scanner to 16-pin port
3. **Snapshot Data Review**:
– Examine vehicle vitals at code triggering
4. **Component Testing**:
– Circuit analysis on sensors
