## Vehicle Code Readers
### Code Retrieval vs System Analysis Tools
Display scanners provide error identifiers like **P0171** or **C1234**, requiring external decoding. Diagnostic scanners like the Innova 5610 offer dynamic metrics including:
– Thermal sensor readings
– Air-fuel ratio

## Diagnostic Trouble Code Structure
Vehicle-specific fault markers follows this pattern:
1. **Component Category**:
– **P** = Powertrain
– **C** = Chassis
2. **Code Type**:
– **0** = SAE standard
– **1** = Brand-exclusive
3. **Functional Area**:
– **3** = Combustion electronics

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Road test to confirm abnormalities
2. **System Interrogation**:
– Connect diagnostic tool to 16-pin port
3. **Freeze Frame Analysis**:
– Examine vehicle vitals at error occurrence
4. **System Validation**:
– Electrical measurements on actuators
