## Vehicle Code Readers
### Code Retrieval vs System Analysis Tools
Entry-level tools provide fault codes like **P0171** or **C1234**, requiring additional research. Professional tools like the BlueDriver Pro offer real-time data including:
– Engine coolant temperature
– Air-fuel ratio

## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Powertrain
– **C** = Suspension/Brakes
2. **Manufacturer Specification**:
– **0** = Generic code
– **1** = Brand-exclusive
3. **Subsystem**:
– **3** = Combustion electronics

## Diagnostic Process Steps
1. **Problem Confirmation**:
– Operational evaluation to confirm abnormalities
2. **Code Retrieval**:
– Connect diagnostic tool to DLC connector
3. **System Condition Capture**:
– Examine vehicle vitals at error occurrence
4. **System Validation**:
– Multimeter checks on sensors
