## Vehicle Code Readers
### Basic vs. Advanced Readers
Display scanners provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring external decoding. Diagnostic scanners like the BlueDriver Pro offer dynamic metrics including:
– Thermal sensor readings
– Fuel trim values

## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Powertrain
– **C** = Suspension/Brakes
2. **Manufacturer Specification**:
– **0** = Generic code
– **1** = Manufacturer-specific
3. **Functional Area**:
– **3** = Combustion electronics

## Troubleshooting Protocol
1. **Problem Confirmation**:
– Road test to confirm abnormalities
2. **Code Retrieval**:
– Connect OBD-II scanner to vehicle interface
3. **Snapshot Data Review**:
– Examine engine parameters at code triggering
4. **System Validation**:
– Multimeter checks on sensors
