## OBD-II Scanner Types

### Code Retrieval vs System Analysis Tools

Basic code readers provide error identifiers like **P0171** or **C1234**, requiring external decoding. Diagnostic scanners like the BlueDriver Pro offer real-time data including:

– Coolant heat levels

– Air-fuel ratio

## Error Code Composition

Vehicle-specific fault markers follows this pattern:

1. **Component Category**:

– **P** = Powertrain

– **C** = Suspension/Brakes

2. **Code Type**:

– **0** = Universal definition

– **1** = OEM-defined

3. **Functional Area**:

– **3** = Combustion electronics

## Vehicle Analysis Procedure

1. **Initial Assessment**:

– Operational evaluation to replicate issues

2. **System Interrogation**:

– Connect code reader to DLC connector

3. **System Condition Capture**:

– Examine operational metrics at time of fault

4. **Component Testing**:

– Multimeter checks on control modules
