## Vehicle Code Readers
### Display vs. Diagnostic Scanners
Display scanners provide fault codes like **P0171** or **C1234**, requiring manual interpretation. Diagnostic scanners like the BlueDriver Pro offer real-time data including:
– Coolant heat levels
– Air-fuel ratio

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **Component Category**:
– **P** = Powertrain
– **C** = Chassis
2. **Code Type**:
– **0** = SAE standard
– **1** = OEM-defined
3. **Subsystem**:
– **3** = Ignition system

## Troubleshooting Protocol
1. **Initial Assessment**:
– Operational evaluation to replicate issues
2. **DTC Extraction**:
– Connect diagnostic tool to DLC connector
3. **Freeze Frame Analysis**:
– Examine operational metrics at code triggering
4. **Component Testing**:
– Electrical measurements on sensors
