Introduction
The scan tool interfaces with the electronic control system of a vehicle to retrieve diagnostic
trouble codes (DTCs) and access serial data stream information. Various vehicle control systems,

scan tool. The scan tool is capable of graphing up to four live data parameters on a single screen.
