Using an OBD2 scanner offers several benefits:

• Early Issue Detection: Identify problems before they become major repairs.
• Cost Savings: Diagnose issues yourself, avoiding expensive mechanic fees.
• Informed Decisions: Understand the problem before taking your car to a mechanic, ensuring transparency.
• Maintenance: Monitor your vehicle’s health and performance.

1.3. Common OBD2 Terms

• DTC (Diagnostic Trouble Code): A code stored by the vehicle’s computer indicating a problem.
• MIL (Malfunction Indicator Lamp): Also known as the “check engine light.”
• Live Data: Real-time information from the vehicle’s sensors.
• Freeze Frame Data: A snapshot of data when a DTC was stored.
