1. Understanding OBD2 Scanners

1.1. What is an OBD2 Scanner?

An OBD2 scanner is a device that communicates with a car’s Engine Control Unit (ECU) via a standardized port, typically located under the driver’s side dashboard, to diagnose issues, monitor performance, and ensure the vehicle operates optimally. OBD stands for On-Board Diagnostics, with “2” indicating the second generation of this technology.

1.2. Why Use an OBD2 Scanner?

Using an OBD2 scanner helps resolve problems and maintain your vehicle by reading the ECU for logged issues, including those that may not activate the Engine Management Light (EML) on the dashboard. The ECU can also provide insights into when the engine needs servicing and whether specific equipment is functioning correctly.
