## Vehicle Code Readers
### Basic vs. Advanced Readers
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
– Fuel trim values

## DTC Format Breakdown
Each 5-character code follows this pattern:
1. **Module Designator**:
– **P** = Drivetrain
– **C** = Suspension/Brakes
2. **Code Type**:
– **0** = Generic code
– **1** = Manufacturer-specific
3. **Component Group**:
– **3** = Ignition system
—
## Diagnostic Process Steps
1. **Initial Assessment**:
– Road test to verify symptoms
2. **System Interrogation**:
– Connect diagnostic tool to vehicle interface
3. **Freeze Frame Analysis**:
– Examine operational metrics at error occurrence
4. **Part Verification**:
– Multimeter checks on actuators
