## Diagnostic Tool Categories
### Display vs. Diagnostic Scanners
Entry-level tools provide error identifiers like **P0171** or **C1234**, requiring external decoding. Diagnostic scanners like the Innova 5610 offer live parameters including:
– Coolant heat levels
– Air-fuel ratio

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

## Diagnostic Process Steps
1. **Problem Confirmation**:
– Road test to confirm abnormalities
2. **System Interrogation**:
– Connect code reader to vehicle interface
3. **Snapshot Data Review**:
– Examine operational metrics at error occurrence
4. **Component Testing**:
– Multimeter checks on control modules
