## Diagnostic Tool Categories
### Code Retrieval vs System Analysis Tools
Entry-level tools provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring external decoding. Diagnostic scanners like the BlueDriver Pro offer live parameters including:
– Engine coolant temperature
– Air-fuel ratio

## DTC Format Breakdown
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Powertrain
– **C** = Chassis
2. **Code Type**:
– **0** = Generic code
– **1** = Brand-exclusive
3. **Functional Area**:
– **3** = Combustion electronics

## Diagnostic Process Steps
1. **Symptom Verification**:
– Road test to confirm abnormalities
2. **Code Retrieval**:
– Connect diagnostic tool to vehicle interface
3. **System Condition Capture**:
– Examine operational metrics at code triggering
4. **Part Verification**:
– Circuit analysis on sensors
