  • Trip Computers
The ScanGauge II automatically tracks and stores data for 4 Trips.
The CURRENT trip is restarted after the engine has been off for more than 3 minutes. The TODAY trip is restarted after the vehicle has not moved for 9 hours. The data from TODAY is moved to PREVIOUS DAY when it is restarted. This way, you don't have to reset the trip computers when you start a trip. There is also a TANK Trip which you reset when you fill up the tank. It can provide you with "to empty" data as well as other useful information. The information is available anytime during the trip. The CURRENT trip can be reset. This is useful for making fuel economy measurements at a steady speed. 
The GAUGE mode can display instantaneous fuel economy, but small variations in throttle, terrain or even wind will cause this to wander around some. The CURRENT trip computer and its RESET capability can smooth this out over a longer distance. A demonstration of how to do this can be chosen below. 
The TRIP modes in the ScanGauge II can be used to save gas. Improved driving habits can improve fuel economy by up to 30% according to a US Government source. The ScanGauge II lets you try different driving techniques and routes and gives quick feedback on how they affect fuel use.
Digital Gauges
12 Built-in Realtime Digitial Guages 
The ScanGauge II can display up to 4 of 12 possible gauges at one time. The units of measure can be changed and the rate of update can be increased or decreased.
Scan Tool
Check for Diagnostic Trouble Codes
The ScanGauge II can check for Diagnostic Trouble Codes (DTCs) and if found, can display how many there are and the Trouble Codes themselves.Using the internet or repair manuals, these can be translated to the failed component and repairs can be made.
Data captured when the Trouble Code was set can be recalled to help troubleshoot the problems (was the temperature hot or cold, speed high or low, etc.). The ScanGauge II can be used to clear the trouble codes and data which will turn off the warning (Check Engine, Service Engine soon, etc.) lamp.
Some states now require that vehicle self tests have been completed since the codes were last cleared, before running emissions checks. The ScanGauge reports this "Readiness".
