The 3100g Code Reader incorporates the capability to retrieve and display “Vehicle Information” (the VIN and controller ID numbers) to determine the version of programming in the vehicle’s computer. *Not all vehicles will support this function.

We always recommend connecting the Code Reader to your vehicle first, before turning on the ignition or starting the vehicle. So long as this procedure is followed, you can use the Code Reader on the vehicle while it is running.
IMPORTANT: If it is necessary to drive the vehicle while observing the Code Reader's display (such as when performing a Drive Cycle), ALWAYS have a second person help you. One person should drive while the second person observes the Code Reader's display.

No. it won't  stream Live Data and it doesn’t have bi-directional functions. Please refer to Innova’s Scan Tools for Live Data capabilities. 

All of the Innova Code Readers and Scan Tools support all 1996 and newer OBD-II certified vehicles, including diesels, which weigh less than 8,500lbs Gross Vehicle Weight and were sold in the United States or Canada. Vehicles that weigh more than 8500lbs Gross Vehicle Weight (GVW) are considered “heavy duty vehicles,” and are not required to be OBD2-compliant. If you do not know if your vehicle is OBD-II certified, you can check your emissions label under the hood, found typically on the roof of the hood, or near the radiator. Vehicles sold in other countries, although similar, are not configured the same as vehicles sold in the United States and Canada, and our tools may not be able to link to them. There are times when our tools will link to vehicles sold outside the United States or Canada, but this functionality is not guaranteed.
