## Diagnostic Tool Categories
### Basic vs. Advanced Readers
Display scanners provide fault codes like **P0171** or **C1234**, requiring external decoding. Advanced systems like the Innova 5610 offer live parameters including:
– Engine coolant temperature
– Air-fuel ratio

## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **System Identifier**:
– **P** = Engine/Transmission
– **C** = Undercarriage
2. **Standardization Level**:
– **0** = Universal definition
– **1** = OEM-defined
3. **Component Group**:
– **3** = Spark components

## Vehicle Analysis Procedure
1. **Symptom Verification**:
– Driving simulation 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**:
– Multimeter checks on sensors
