## Diagnostic Tool Categories
### Basic vs. Advanced Readers
Basic code readers provide error identifiers like **P0171** or **C1234**, requiring additional research. Advanced systems like the Innova 5610 offer real-time data including:
– Thermal sensor readings
– Combustion mixture balance

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Suspension/Brakes
2. **Code Type**:
– **0** = SAE standard
– **1** = Manufacturer-specific
3. **Subsystem**:
– **3** = Ignition system

## Vehicle Analysis Procedure
1. **Initial Assessment**:
– Road test to replicate issues
2. **Code Retrieval**:
– Connect diagnostic tool to DLC connector
3. **Freeze Frame Analysis**:
– Examine vehicle vitals at error occurrence
4. **Part Verification**:
– Electrical measurements on control modules
