## OBD-II Scanner Types
### Basic vs. Advanced Readers
Basic code readers provide fault codes like **P0171** or **C1234**, requiring additional research. Advanced systems like the Innova 5610 offer real-time data including:
– Engine coolant temperature
– Air-fuel ratio

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Undercarriage
2. **Standardization Level**:
– **0** = SAE standard
– **1** = Brand-exclusive
3. **Functional Area**:
– **3** = Spark components

## Diagnostic Process Steps
1. **Symptom Verification**:
– Road test to verify symptoms
2. **DTC Extraction**:
– Connect code reader to DLC connector
3. **System Condition Capture**:
– Examine vehicle vitals at error occurrence
4. **Part Verification**:
– Multimeter checks on sensors
