### Display vs. Diagnostic Scanners
Entry-level tools provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring additional research. Advanced systems like the Ancel BD310 offer dynamic metrics including:
– Coolant heat levels
– Combustion mixture balance

## DTC Format Breakdown
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Powertrain
– **C** = Suspension/Brakes
2. **Manufacturer Specification**:
– **0** = SAE standard
– **1** = OEM-defined
3. **Component Group**:
– **3** = Combustion electronics

## Diagnostic Process Steps
1. **Symptom Verification**:
– Operational evaluation to replicate issues
2. **DTC Extraction**:
– Connect OBD-II scanner to 16-pin port
3. **System Condition Capture**:
– Examine operational metrics at error occurrence
4. **System Validation**:
– Multimeter checks on sensors
