## Diagnostic Tool Categories
### Display vs. Diagnostic Scanners
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring manual interpretation. Advanced systems like the BlueDriver Pro offer dynamic metrics including:
– Thermal sensor readings
– Combustion mixture balance

## Error Code Composition
Vehicle-specific fault markers follows this pattern:
1. **Component Category**:
– **P** = Engine/Transmission
– **C** = Chassis
2. **Code Type**:
– **0** = Generic code
– **1** = OEM-defined
3. **Functional Area**:
– **3** = Combustion electronics

## Vehicle Analysis Procedure
1. **Initial Assessment**:
– Road test to confirm abnormalities
2. **Code Retrieval**:
– Connect diagnostic tool to 16-pin port
3. **Snapshot Data Review**:
– Examine engine parameters at time of fault
4. **Part Verification**:
– Electrical measurements on sensors
