must first stop communication with the vehicle in order to exit from the Scanner function. A
warning message displays if you attempt to exit from the Scanner while it is communicating with
the vehicle ECM.

Damage to the vehicle electronic control module (ECM) may occur if communication is disrupted.
Make sure the data cable and the USB cable are properly connected at all times during testing.
