## Vehicle Code Readers
### Display vs. Diagnostic Scanners
Display scanners provide error identifiers like **P0171** or **C1234**, requiring additional research. Diagnostic scanners like the Ancel BD310 offer real-time data including:
– Engine coolant temperature
– Air-fuel ratio

## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Engine/Transmission
– **C** = Undercarriage
2. **Standardization Level**:
– **0** = Universal definition
– **1** = Brand-exclusive
3. **Subsystem**:
– **3** = Combustion electronics

## Troubleshooting Protocol
1. **Symptom Verification**:
– Operational evaluation to confirm abnormalities
2. **System Interrogation**:
– Connect OBD-II scanner to vehicle interface
3. **Snapshot Data Review**:
– Examine vehicle vitals at time of fault
4. **Component Testing**:
– Multimeter checks on actuators
