Powering On/Off and Emergency Shutdown

To manually turn on the diagnostic tool, press and release the Power button.

The diagnostic tool will automatically turn on when:

● a live AC power supply is connected to the diagnostic tool
● the Data Cable is connected to a vehicle (that has 12VDC at the data link connector (DLC))

All vehicle communication must be stopped BEFORE turning off the diagnostic tool. A warning message displays if you attempt to turn the diagnostic tool off while communicating with the vehicle. Forcing a shut down while communicating may lead to ECM problems on some vehicles. Never disconnect the Data Cable when the diagnostic tool is communicating with the vehicle ECM.

1. Press the N/Cancel button or select the Back or Home icon to navigate to the Home screen.

If applicable, a “stopping communication” message appears briefly before the Home screen displays.

2. If applicable, disconnect the Data Cable from the vehicle.
3. Press and release the Power button.

A confirmation screen displays.

4. Press the Y/Accept button or select OK from the menu to turn the diagnostic tool off. To continue operating, press the N/Cancel button or select Cancel from the menu.

Using the emergency shutdown procedure while communicating with the vehicle ECM may lead to ECM problems on some vehicles.

During normal operation turn the diagnostic tool off using the Turning Off procedure above. The emergency shutdown procedure should only be used If the diagnostic tool does not respond to navigation or control buttons or exhibits erratic operation. To force an emergency shutdown, press and hold the Power button for five seconds until the diagnostic tool turns off.
