### Code Retrieval vs System Analysis Tools
Entry-level tools provide error identifiers like **P0171** or **C1234**, requiring additional research. Diagnostic scanners like the BlueDriver Pro offer live parameters including:
– Coolant heat levels
– Combustion mixture balance

## Diagnostic Trouble Code Structure
Standard alphanumeric identifiers follows this pattern:
1. **System Identifier**:
– **P** = Drivetrain
– **C** = Undercarriage
2. **Manufacturer Specification**:
– **0** = Universal definition
– **1** = OEM-defined
3. **Component Group**:
– **3** = Ignition system
—
## Diagnostic Process Steps
1. **Symptom Verification**:
– Road test to verify symptoms
2. **DTC Extraction**:
– Connect diagnostic tool to DLC connector
3. **System Condition Capture**:
– Examine engine parameters at time of fault
4. **Component Testing**:
– Electrical measurements on sensors
