## Diagnostic Tool Categories
### Basic vs. Advanced Readers
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring manual interpretation. Advanced systems like the BlueDriver Pro offer live parameters including:
– Coolant heat levels
– Combustion mixture balance

## Error Code Composition
Each 5-character code follows this pattern:
1. **System Identifier**:
– **P** = Powertrain
– **C** = Undercarriage
2. **Code Type**:
– **0** = Universal definition
– **1** = Manufacturer-specific
3. **Subsystem**:
– **3** = Spark components

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Road test to replicate issues
2. **Code Retrieval**:
– Connect OBD-II scanner to DLC connector
3. **Snapshot Data Review**:
– Examine operational metrics at code triggering
4. **Part Verification**:
– Circuit analysis on control modules
