## DTC Format Breakdown
Standard alphanumeric identifiers follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Undercarriage
2. **Standardization Level**:
– **0** = Generic code
– **1** = Manufacturer-specific
3. **Component Group**:
– **3** = Combustion electronics
—
## Troubleshooting Protocol
1. **Initial Assessment**:
– Driving simulation to confirm abnormalities
2. **Code Retrieval**:
– Connect OBD-II scanner to DLC connector
3. **Freeze Frame Analysis**:
– Examine vehicle vitals at time of fault
4. **Part Verification**:
– Electrical measurements on sensors
