1. What is a Car Scanner Diagnostic Tool?

A car scanner diagnostic tool, also known as an OBD (On-Board Diagnostics) scanner, is an electronic device used to interface with a vehicle’s computer system. It reads diagnostic trouble codes (DTCs) and other data from the car’s various sensors and systems, helping to identify potential problems. According to a study by the National Institute for Automotive Service Excellence (ASE), using diagnostic tools can reduce repair time by up to 40%.

1.1. The Purpose of a Car Diagnostic Tool

The main purpose of a car diagnostic tool is to:

• Identify the source of a problem indicated by the check engine light.
• Monitor the performance of various vehicle systems.
• Reset the check engine light after repairs.
• Provide real-time data for troubleshooting.
