## OBD-II Scanner Types
### Display vs. Diagnostic Scanners
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring manual interpretation. Advanced systems like the Ancel BD310 offer real-time data including:
– Coolant heat levels
– Combustion mixture balance

## DTC Format Breakdown
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Powertrain
– **C** = Chassis
2. **Manufacturer Specification**:
– **0** = Generic code
– **1** = Brand-exclusive
3. **Subsystem**:
– **3** = Ignition system

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Driving simulation to replicate issues
2. **System Interrogation**:
– Connect OBD-II scanner to DLC connector
3. **Freeze Frame Analysis**:
– Examine vehicle vitals at time of fault
4. **System Validation**:
– Electrical measurements on sensors
