## OBD-II Scanner Types
### Basic vs. Advanced Readers
Display scanners provide fault codes like **P0171** or **C1234**, requiring manual interpretation. Professional tools like the Ancel BD310 offer live parameters including:
– Thermal sensor readings
– Combustion mixture balance

## Error Code Composition
Vehicle-specific fault markers follows this pattern:
1. **Component Category**:
– **P** = Drivetrain
– **C** = Undercarriage
2. **Standardization Level**:
– **0** = SAE standard
– **1** = OEM-defined
3. **Functional Area**:
– **3** = Combustion electronics

## Diagnostic Process Steps
1. **Initial Assessment**:
– Operational evaluation to replicate issues
2. **DTC Extraction**:
– Connect diagnostic tool to vehicle interface
3. **Freeze Frame Analysis**:
– Examine engine parameters at time of fault
4. **Component Testing**:
– Multimeter checks on actuators
