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

## DTC Format Breakdown
Each 5-character code follows this pattern:
1. **Module Designator**:
– **P** = Engine/Transmission
– **C** = Suspension/Brakes
2. **Manufacturer Specification**:
– **0** = Universal definition
– **1** = OEM-defined
3. **Functional Area**:
– **3** = Spark components

## Diagnostic Process Steps
1. **Symptom Verification**:
– Road test to verify symptoms
2. **System Interrogation**:
– Connect diagnostic tool to vehicle interface
3. **Snapshot Data Review**:
– Examine vehicle vitals at time of fault
4. **Component Testing**:
– Multimeter checks on control modules
