## OBD-II Scanner Types
### Display vs. Diagnostic Scanners
Entry-level tools provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring external decoding. Professional tools like the Ancel BD310 offer live parameters including:
– Coolant heat levels
– Combustion mixture balance

## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **Component Category**:
– **P** = Powertrain
– **C** = Chassis
2. **Code Type**:
– **0** = SAE standard
– **1** = Manufacturer-specific
3. **Subsystem**:
– **3** = Ignition system
—
## Diagnostic Process Steps
1. **Symptom Verification**:
– Driving simulation to confirm abnormalities
2. **Code Retrieval**:
– Connect OBD-II scanner to vehicle interface
3. **Snapshot Data Review**:
– Examine vehicle vitals at code triggering
4. **System Validation**:
– Circuit analysis on control modules
