## Vehicle Code Readers
### Basic vs. Advanced Readers
Entry-level tools provide fault codes like **P0171** or **C1234**, requiring external decoding. Professional tools like the Ancel BD310 offer real-time data including:
– Thermal sensor readings
– Air-fuel ratio

## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **System Identifier**:
– **P** = Engine/Transmission
– **C** = Chassis
2. **Standardization Level**:
– **0** = SAE standard
– **1** = Manufacturer-specific
3. **Component Group**:
– **3** = Combustion electronics
—
## Troubleshooting Protocol
1. **Symptom Verification**:
– Road test to replicate issues
2. **DTC Extraction**:
– Connect code reader to DLC connector
3. **Snapshot Data Review**:
– Examine vehicle vitals at time of fault
4. **Component Testing**:
– Multimeter checks on control modules
