## Diagnostic Tool Categories
### Display vs. Diagnostic Scanners
Entry-level tools provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring manual interpretation. Professional tools like the Ancel BD310 offer live parameters including:
– Thermal sensor readings
– Combustion mixture balance

## DTC Format Breakdown
Standard alphanumeric identifiers follows this pattern:
1. **System Identifier**:
– **P** = Drivetrain
– **C** = Suspension/Brakes
2. **Standardization Level**:
– **0** = SAE standard
– **1** = Manufacturer-specific
3. **Functional Area**:
– **3** = Combustion electronics

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Operational evaluation to replicate issues
2. **Code Retrieval**:
– Connect diagnostic tool to 16-pin port
3. **Snapshot Data Review**:
– Examine operational metrics at error occurrence
4. **System Validation**:
– Electrical measurements on actuators
