## Diagnostic Tool Categories
### Basic vs. Advanced Readers
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring external decoding. Diagnostic scanners like the BlueDriver Pro offer dynamic metrics including:
– Coolant heat levels
– Fuel trim values

## DTC Format Breakdown
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Powertrain
– **C** = Undercarriage
2. **Code Type**:
– **0** = Universal definition
– **1** = Manufacturer-specific
3. **Subsystem**:
– **3** = Ignition system

## Vehicle Analysis Procedure
1. **Problem Confirmation**:
– Operational evaluation to verify symptoms
2. **DTC Extraction**:
– Connect diagnostic tool to DLC connector
3. **System Condition Capture**:
– Examine vehicle vitals at error occurrence
4. **Part Verification**:
– Multimeter checks on actuators
