## Vehicle Code Readers
### Display vs. Diagnostic Scanners
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring additional research. Diagnostic scanners like the BlueDriver Pro offer dynamic metrics including:
– Engine coolant temperature
– Combustion mixture balance

## DTC Format Breakdown
Each 5-character code follows this pattern:
1. **Component Category**:
– **P** = Engine/Transmission
– **C** = Chassis
2. **Standardization Level**:
– **0** = Generic code
– **1** = Brand-exclusive
3. **Subsystem**:
– **3** = Spark components

## Troubleshooting Protocol
1. **Initial Assessment**:
– Road test to confirm abnormalities
2. **Code Retrieval**:
– Connect OBD-II scanner to vehicle interface
3. **Freeze Frame Analysis**:
– Examine operational metrics at error occurrence
4. **Component Testing**:
– Circuit analysis on actuators
