## Diagnostic Tool Categories
### Code Retrieval vs System Analysis Tools
Basic code readers provide error identifiers like **P0171** or **C1234**, requiring external decoding. Advanced systems like the Ancel BD310 offer dynamic metrics including:
– Engine coolant temperature
– Air-fuel ratio

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

## Diagnostic Process Steps
1. **Initial Assessment**:
– Operational evaluation to verify symptoms
2. **DTC Extraction**:
– Connect diagnostic tool to 16-pin port
3. **Snapshot Data Review**:
– Examine operational metrics at time of fault
4. **Part Verification**:
– Electrical measurements on control modules
