What happens here

With the scanner properly connected, it should power on automatically. The scanner will then proceed to scan the vehicle's onboard computer for any Diagnostic Trouble Codes (DTCs). The screen of the scanner will typically display a message indicating that it is scanning or reading codes. Allow the scanner to complete this process.

Goal: After connecting the scanner, it will automatically power on and begin communicating with your vehicle to retrieve any stored Diagnostic Trouble Codes (DTCs) that caused the warning light.
