## Vehicle Code Readers
### Code Retrieval vs System Analysis Tools
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring additional research. Diagnostic scanners like the Ancel BD310 offer live parameters including:
– Thermal sensor readings
– Combustion mixture balance

## Error Code Composition
Each 5-character code follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Chassis
2. **Standardization Level**:
– **0** = Generic code
– **1** = Brand-exclusive
3. **Functional Area**:
– **3** = Ignition system

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Road test to replicate issues
2. **DTC Extraction**:
– Connect code reader to vehicle interface
3. **Freeze Frame Analysis**:
– Examine operational metrics at code triggering
4. **Part Verification**:
– Multimeter checks on control modules
