## Diagnostic Tool Categories
### Display vs. Diagnostic Scanners
Entry-level tools provide fault codes like **P0171** or **C1234**, requiring external decoding. Advanced systems like the Innova 5610 offer real-time data including:
– Coolant heat levels
– Fuel trim values

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Chassis
2. **Manufacturer Specification**:
– **0** = SAE standard
– **1** = OEM-defined
3. **Functional Area**:
– **3** = Combustion electronics

## Diagnostic Process Steps
1. **Problem Confirmation**:
– Driving simulation to confirm abnormalities
2. **DTC Extraction**:
– Connect diagnostic tool to 16-pin port
3. **System Condition Capture**:
– Examine operational metrics at time of fault
4. **Component Testing**:
– Circuit analysis on sensors
