## Diagnostic Tool Categories
### Basic vs. Advanced Readers
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring manual interpretation. Advanced systems like the BlueDriver Pro offer real-time data including:
– Coolant heat levels
– Combustion mixture balance

## Error Code Composition
Each 5-character code follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Undercarriage
2. **Code Type**:
– **0** = Generic code
– **1** = Manufacturer-specific
3. **Subsystem**:
– **3** = Combustion electronics
—
## Troubleshooting Protocol
1. **Initial Assessment**:
– Driving simulation to confirm abnormalities
2. **DTC Extraction**:
– Connect code reader to 16-pin port
3. **Snapshot Data Review**:
– Examine operational metrics at error occurrence
4. **System Validation**:
– Circuit analysis on actuators
