## Vehicle Code Readers
### Code Retrieval vs System Analysis Tools
Entry-level tools provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring external decoding. Professional tools like the Innova 5610 offer live parameters including:
– Thermal sensor readings
– Combustion mixture balance

## Error Code Composition
Each 5-character code follows this pattern:
1. **System Identifier**:
– **P** = Drivetrain
– **C** = Suspension/Brakes
2. **Standardization Level**:
– **0** = SAE standard
– **1** = Brand-exclusive
3. **Subsystem**:
– **3** = Combustion electronics

## Troubleshooting Protocol
1. **Problem Confirmation**:
– Road test to verify symptoms
2. **Code Retrieval**:
– Connect diagnostic tool to 16-pin port
3. **System Condition Capture**:
– Examine engine parameters at time of fault
4. **Part Verification**:
– Electrical measurements on actuators
