## Diagnostic Tool Categories
### Basic vs. Advanced Readers
Display scanners provide error identifiers like **P0171** or **C1234**, requiring manual interpretation. Diagnostic scanners like the BlueDriver Pro offer real-time data including:
– Thermal sensor readings
– Combustion mixture balance
—
## Error Code Composition
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Drivetrain
– **C** = Undercarriage
2. **Manufacturer Specification**:
– **0** = Universal definition
– **1** = Manufacturer-specific
3. **Functional Area**:
– **3** = Combustion electronics
—
## Troubleshooting Protocol
1. **Symptom Verification**:
– Road test to confirm abnormalities
2. **DTC Extraction**:
– Connect code reader to vehicle interface
3. **System Condition Capture**:
– Examine vehicle vitals at error occurrence
4. **Component Testing**:
– Circuit analysis on sensors
