## Vehicle Code Readers
### Code Retrieval vs System Analysis Tools
Basic code readers provide fault codes like **P0171** or **C1234**, requiring additional research. Professional tools like the Innova 5610 offer live parameters including:
– Engine coolant temperature
– Combustion mixture balance

## Diagnostic Trouble Code Structure
Each 5-character code follows this pattern:
1. **System Identifier**:
– **P** = Drivetrain
– **C** = Suspension/Brakes
2. **Manufacturer Specification**:
– **0** = SAE standard
– **1** = OEM-defined
3. **Subsystem**:
– **3** = Spark components

## Vehicle Analysis Procedure
1. **Initial Assessment**:
– Operational evaluation to replicate issues
2. **Code Retrieval**:
– Connect OBD-II scanner to DLC connector
3. **System Condition Capture**:
– Examine vehicle vitals at time of fault
4. **Part Verification**:
– Multimeter checks on sensors
