## OBD-II Scanner Types
### Basic vs. Advanced Readers
Display scanners provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring additional research. Advanced systems like the BlueDriver Pro offer real-time data including:
– Coolant heat levels
– Combustion mixture balance

## Error Code Composition
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Drivetrain
– **C** = Suspension/Brakes
2. **Standardization Level**:
– **0** = Universal definition
– **1** = Manufacturer-specific
3. **Component Group**:
– **3** = Spark components

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Driving simulation to confirm abnormalities
2. **DTC Extraction**:
– Connect diagnostic tool to DLC connector
3. **Freeze Frame Analysis**:
– Examine vehicle vitals at error occurrence
4. **Component Testing**:
– Circuit analysis on actuators
