## Vehicle Code Readers
### Code Retrieval vs System Analysis Tools
Display scanners provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring external decoding. Diagnostic scanners like the BlueDriver Pro offer live parameters including:
– Thermal sensor readings
– Combustion mixture balance

## DTC Format Breakdown
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Drivetrain
– **C** = Undercarriage
2. **Standardization Level**:
– **0** = SAE standard
– **1** = Manufacturer-specific
3. **Component Group**:
– **3** = Spark components

## Diagnostic Process Steps
1. **Symptom Verification**:
– Driving simulation to verify symptoms
2. **Code Retrieval**:
– Connect diagnostic tool to DLC connector
3. **System Condition Capture**:
– Examine vehicle vitals at time of fault
4. **Part Verification**:
– Circuit analysis on control modules
