## Diagnostic Tool Categories
### Display vs. Diagnostic Scanners
Basic code readers provide fault codes like **P0171** or **C1234**, requiring external decoding. Professional tools like the Ancel BD310 offer live parameters including:
– Coolant heat levels
– Air-fuel ratio

## Diagnostic Trouble Code Structure
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Drivetrain
– **C** = Chassis
2. **Manufacturer Specification**:
– **0** = SAE standard
– **1** = Brand-exclusive
3. **Subsystem**:
– **3** = Ignition system

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Driving simulation to replicate issues
2. **Code Retrieval**:
– Connect diagnostic tool to vehicle interface
3. **Freeze Frame Analysis**:
– Examine vehicle vitals at time of fault
4. **System Validation**:
– Circuit analysis on sensors
