## Vehicle Code Readers
### Basic vs. Advanced Readers
Display scanners provide fault codes like **P0171** or **C1234**, requiring external decoding. Professional tools like the BlueDriver Pro offer live parameters including:
– Coolant heat levels
– Air-fuel ratio

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **System Identifier**:
– **P** = Drivetrain
– **C** = Chassis
2. **Manufacturer Specification**:
– **0** = Generic code
– **1** = Brand-exclusive
3. **Component Group**:
– **3** = Ignition system
—
## Diagnostic Process Steps
1. **Initial Assessment**:
– Driving simulation to verify symptoms
2. **Code Retrieval**:
– Connect code reader to vehicle interface
3. **Snapshot Data Review**:
– Examine operational metrics at error occurrence
4. **System Validation**:
– Circuit analysis on control modules
