If not, the update may fail in progress. It is strongly recommended to connect the power supply cable to the diagnostic terminal during the update procedure.
2. Connect the USB cable between the VCI and the diagnostic terminal.
NOTE:
When performing the update using the GDS, wireless communication between the VCI and the diagnostic terminal is NOT available. Therefore, be sure to connect the USB cable between the VCI and the diagnostic terminal.
3. Connect the 16-pin DLC cable from the VCI into the vehicle's 16-pin connector under the driver side instrument panel.
4. Turn on the VCI and diagnostic terminal with the ignition key in the ON position.
