1. What is a Diagnostic Scanner Car?

A diagnostic scanner car, also known as an OBD (On-Board Diagnostics) scanner, is an electronic tool used to interface with a vehicle’s computer system. It reads diagnostic trouble codes (DTCs) to identify malfunctions in various systems, such as the engine, transmission, ABS, and airbags. These scanners provide valuable insights into a vehicle’s health, enabling accurate and efficient repairs.

Diagnostic scanners connect to a car’s OBD port, typically located under the dashboard. Once connected, the scanner communicates with the vehicle’s computer, accessing data from various sensors and systems. This data is then translated into readable codes and information that can help mechanics and car owners pinpoint problems.
