## Vehicle Code Readers
### Basic vs. Advanced Readers
Display scanners provide error identifiers like **P0171** or **C1234**, requiring additional research. Diagnostic scanners like the BlueDriver Pro offer dynamic metrics including:
– Thermal sensor readings
– Combustion mixture balance

## Error Code Composition
Each 5-character code follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Undercarriage
2. **Manufacturer Specification**:
– **0** = SAE standard
– **1** = Brand-exclusive
3. **Functional Area**:
– **3** = Ignition system
