## Vehicle Code Readers
### Basic vs. Advanced Readers
Display scanners provide fault codes like **P0171** or **C1234**, requiring additional research. Professional tools like the BlueDriver Pro offer real-time data including:
– Engine coolant temperature
– Air-fuel ratio

## Diagnostic Trouble Code Structure
Standard alphanumeric identifiers follows this pattern:
1. **Module Designator**:
– **P** = Engine/Transmission
– **C** = Undercarriage
2. **Code Type**:
– **0** = Generic code
– **1** = OEM-defined
3. **Functional Area**:
– **3** = Combustion electronics

## Diagnostic Process Steps
1. **Symptom Verification**:
– Driving simulation to verify symptoms
2. **System Interrogation**:
– Connect code reader to vehicle interface
3. **Freeze Frame Analysis**:
– Examine engine parameters at code triggering
4. **Part Verification**:
– Multimeter checks on actuators
