## Diagnostic Tool Categories
### Basic vs. Advanced Readers
Display scanners provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring external decoding. Professional tools like the BlueDriver Pro offer dynamic metrics including:
– Coolant heat levels
– Combustion mixture balance

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **Component Category**:
– **P** = Engine/Transmission
– **C** = Chassis
2. **Code Type**:
– **0** = Universal definition
– **1** = OEM-defined
3. **Component Group**:
– **3** = Ignition system
—
## Troubleshooting Protocol
1. **Initial Assessment**:
– Road test to confirm abnormalities
2. **System Interrogation**:
– Connect code reader to vehicle interface
3. **System Condition Capture**:
– Examine vehicle vitals at time of fault
4. **Component Testing**:
– Multimeter checks on actuators
