## Vehicle Code Readers
### Display vs. Diagnostic Scanners
Entry-level tools provide error identifiers like **P0171** or **C1234**, requiring additional research. Advanced systems like the Innova 5610 offer real-time data including:
– Engine coolant temperature
– Combustion mixture balance

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Engine/Transmission
– **C** = Suspension/Brakes
2. **Code Type**:
– **0** = Universal definition
– **1** = Brand-exclusive
3. **Component Group**:
– **3** = Ignition system
