## Vehicle Code Readers
### Basic vs. Advanced Readers
Basic code readers provide fault codes like **P0171** or **C1234**, requiring external decoding. Diagnostic scanners like the BlueDriver Pro offer live parameters including:
– Thermal sensor readings
– Combustion mixture balance

## Diagnostic Trouble Code Structure
Standard alphanumeric identifiers follows this pattern:
1. **System Identifier**:
– **P** = Engine/Transmission
– **C** = Undercarriage
2. **Manufacturer Specification**:
– **0** = SAE standard
– **1** = OEM-defined
3. **Subsystem**:
– **3** = Combustion electronics
