## Diagnostic Tool Categories
### Basic vs. Advanced Readers
Display scanners provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring additional research. Professional tools like the BlueDriver Pro offer dynamic metrics including:
– Engine coolant temperature
– Air-fuel ratio

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Suspension/Brakes
2. **Standardization Level**:
– **0** = Generic code
– **1** = Manufacturer-specific
3. **Subsystem**:
– **3** = Spark components

## Diagnostic Process Steps
1. **Initial Assessment**:
– Road test to confirm abnormalities
2. **System Interrogation**:
– Connect diagnostic tool to DLC connector
3. **Freeze Frame Analysis**:
– Examine operational metrics at time of fault
4. **Component Testing**:
– Circuit analysis on control modules
