## Vehicle Code Readers
### Basic vs. Advanced Readers
Entry-level tools provide fault codes like **P0171** or **C1234**, requiring additional research. Professional tools like the Innova 5610 offer live parameters including:
– Coolant heat levels
– Air-fuel ratio
—
## Error Code Composition
Vehicle-specific fault markers follows this pattern:
1. **System Identifier**:
– **P** = Drivetrain
– **C** = Undercarriage
2. **Code Type**:
– **0** = Generic code
– **1** = OEM-defined
3. **Functional Area**:
– **3** = Spark components
—
## Troubleshooting Protocol
1. **Initial Assessment**:
– Driving simulation to verify symptoms
2. **System Interrogation**:
– Connect diagnostic tool to DLC connector
3. **Snapshot Data Review**:
– Examine vehicle vitals at code triggering
4. **Component Testing**:
– Multimeter checks on sensors
