## Diagnostic Tool Categories
### Basic vs. Advanced Readers
Entry-level tools provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring external decoding. Professional tools like the Innova 5610 offer dynamic metrics including:
– Coolant heat levels
– Air-fuel ratio

## Diagnostic Trouble Code Structure
Each 5-character code follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Suspension/Brakes
2. **Code Type**:
– **0** = Universal definition
– **1** = Brand-exclusive
3. **Functional Area**:
– **3** = Combustion electronics
