1. What is a Car Diagnostic App?

A car diagnostic app is a software application designed to read and interpret data from your vehicle’s onboard diagnostic system (OBD II). These apps connect to your car’s computer via an OBD II adapter, which plugs into the OBD II port, typically located under the dashboard. The app then translates the data into understandable information, providing insights into your car’s performance, potential issues, and overall health. According to a report by IBISWorld, the automotive repair and maintenance industry is constantly evolving, with technology playing a crucial role.

Key Features of Car Diagnostic Apps:

• Reading Diagnostic Trouble Codes (DTCs): Identifying the specific codes indicating a problem.
