## Vehicle Code Readers
### Basic vs. Advanced Readers
Display scanners provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring manual interpretation. Professional tools like the BlueDriver Pro offer live parameters including:
– Thermal sensor readings
– Air-fuel ratio

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Undercarriage
2. **Manufacturer Specification**:
– **0** = Generic code
– **1** = Brand-exclusive
3. **Functional Area**:
– **3** = Combustion electronics

## Diagnostic Process Steps
1. **Problem Confirmation**:
– Road test to replicate issues
2. **DTC Extraction**:
– Connect code reader to vehicle interface
3. **System Condition Capture**:
– Examine vehicle vitals at time of fault
4. **Component Testing**:
– Electrical measurements on actuators
