## OBD-II Scanner Types
### Code Retrieval vs System Analysis Tools
Entry-level tools provide error identifiers like **P0171** or **C1234**, requiring additional research. Advanced systems like the Ancel BD310 offer live parameters including:
– Coolant heat levels
– Air-fuel ratio

## DTC Format Breakdown
Each 5-character code follows this pattern:
1. **System Identifier**:
– **P** = Powertrain
– **C** = Chassis
2. **Standardization Level**:
– **0** = SAE standard
– **1** = Brand-exclusive
3. **Component Group**:
– **3** = Ignition system

## Diagnostic Process Steps
1. **Initial Assessment**:
– Driving simulation to verify symptoms
2. **System Interrogation**:
– Connect diagnostic tool to DLC connector
3. **System Condition Capture**:
– Examine operational metrics at error occurrence
4. **Component Testing**:
– Electrical measurements on control modules
