## Vehicle Code Readers
### Display vs. Diagnostic Scanners
Basic code readers provide fault codes like **P0171** or **C1234**, requiring additional research. Diagnostic scanners like the Innova 5610 offer dynamic metrics including:
– Coolant heat levels
– Air-fuel ratio

## Error Code Composition
Standard alphanumeric identifiers follows this pattern:
1. **Component Category**:
– **P** = Drivetrain
– **C** = Chassis
2. **Standardization Level**:
– **0** = Universal definition
– **1** = Brand-exclusive
3. **Subsystem**:
– **3** = Spark components

## Diagnostic Process Steps
1. **Problem Confirmation**:
– Operational evaluation to replicate issues
2. **Code Retrieval**:
– Connect code reader to DLC connector
3. **Snapshot Data Review**:
– Examine engine parameters at time of fault
4. **System Validation**:
– Electrical measurements on sensors
