## Vehicle Code Readers
### Display vs. Diagnostic Scanners
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring manual interpretation. Professional tools like the BlueDriver Pro offer live parameters including:
– Coolant heat levels
– Combustion mixture balance

## Error Code Composition
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Engine/Transmission
– **C** = Chassis
2. **Manufacturer Specification**:
– **0** = SAE standard
– **1** = Brand-exclusive
3. **Functional Area**:
– **3** = Ignition system

## Diagnostic Process Steps
1. **Symptom Verification**:
– Road test to replicate issues
2. **DTC Extraction**:
– Connect OBD-II scanner to vehicle interface
3. **Freeze Frame Analysis**:
– Examine operational metrics at time of fault
4. **Component Testing**:
– Multimeter checks on sensors
