## Vehicle Code Readers
### Code Retrieval vs System Analysis Tools
Entry-level tools provide diagnostic trouble codes (DTCs) like **P0171** or **C1234**, requiring additional research. Diagnostic scanners like the Innova 5610 offer dynamic metrics including:
– Thermal sensor readings
– Combustion mixture balance

## DTC Format Breakdown
Each 5-character code follows this pattern:
1. **Module Designator**:
– **P** = Powertrain
– **C** = Chassis
2. **Standardization Level**:
– **0** = Universal definition
– **1** = OEM-defined
3. **Component Group**:
– **3** = Ignition system

## Vehicle Analysis Procedure
1. **Initial Assessment**:
– Operational evaluation to verify symptoms
2. **Code Retrieval**:
– Connect code reader to vehicle interface
3. **Freeze Frame Analysis**:
– Examine operational metrics at error occurrence
4. **Part Verification**:
– Electrical measurements on actuators
