Can I use the ScanGauge II to tell how fast and how far my teenage son drove the car last night?
Yes. This information is stored in the trip computer and it can be recalled by you for up to a day after he used it. What if my son disconnects the ScanGauge II while he is using the car. If the ScanGauge II was disconnected during the trip, a disconnect indicator will be displayed in the trip data.
