Performance Monitor Home

Provides access to all the Performance Monitor Features.

Arming the Performance Monitor

Arm the ScanGaugeII Performance Monitor just before you’re ready to record your run. The ScanGaugeII will automatically start recording when it detects change in speed.

Performance Recording Screen

Once the ScanGauge begins recording, it will display your time and speed in real-time. You can stop the recording at any time by pressing the STOP button.

Performance Data Screen

You can step through the recorded data.  ScanGaugeII can store up to 10 individual runs.

Turn off That Check Engine Light!

The ScanGaugeII 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.

Clear Trouble Codes

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 lamp.

Is Your Vehicle Ready for Emissions Testing?

Some states now require that before running emissions checks, the vehicle self-tests have to be completed and cleared.  The ScanGaugeII reports this “Readiness”.

Read & Clear Pending Trouble Codes

If no codes are found and your Check Engine light is still on, your vehicle may be storing pending codes. The ScanGaugeII provides a method to force clear any detected or undetected Trouble Codes with just a few button pushes.
