## Vehicle Code Readers
### Code Retrieval vs System Analysis Tools
Basic code readers provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring external decoding. Professional tools like the Innova 5610 offer dynamic metrics including:
– Coolant heat levels
– Combustion mixture balance
—
## Error Code Composition
Each 5-character code follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Suspension/Brakes
2. **Manufacturer Specification**:
– **0** = Universal definition
– **1** = OEM-defined
3. **Component Group**:
– **3** = Combustion electronics
—
## Troubleshooting Protocol
1. **Symptom Verification**:
– Road test to replicate issues
2. **System Interrogation**:
– Connect code reader to 16-pin port
3. **System Condition Capture**:
– Examine operational metrics at error occurrence
4. **Part Verification**:
– Electrical measurements on control modules
