## Vehicle Code Readers
### Basic vs. Advanced Readers
Entry-level tools provide fault codes like **P0171** or **C1234**, requiring external decoding. Diagnostic scanners like the BlueDriver Pro offer real-time data including:
– Engine coolant temperature
– Fuel trim values

## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **Component Category**:
– **P** = Powertrain
– **C** = Suspension/Brakes
2. **Standardization Level**:
– **0** = Generic code
– **1** = Manufacturer-specific
3. **Functional Area**:
– **3** = Ignition system

## Diagnostic Process Steps
1. **Initial Assessment**:
– Operational evaluation to verify symptoms
2. **System Interrogation**:
– Connect diagnostic tool to 16-pin port
3. **Snapshot Data Review**:
– Examine operational metrics at time of fault
4. **System Validation**:
– Electrical measurements on sensors
