The battery charger is connected to the vehicle battery and remains connected for the duration of the software update. • Battery voltage must remain above 12.5 volts for the duration of the software update. Failure to do so may cause the update to fail, which could result in damage to the control module. Control modules damaged by insufficient voltage will not be covered. The screen saver and power saving settings are off. • Failure to do so may result in the tester entering power save mode during the software update, which could result in damage to the control module. The VAS Diagnostic Tester is plugged in using the supplied power adapters. • Under no circumstances should the tester be used on battery power alone during the software update. Failure to do so may result in the tester powering off during the update, which could result in damage to the control module. The VAS Diagnostics Interface MUST ONLY be connected to the tester with a USB cable. • Performing a software update using a Bluetooth or WiFi connection increases the risk of losing connection during the update, which could result in damage to the control module. It also greatly increases the time required to perform the update. Requests for additional time or parts will be denied if the GFF log shows the update was performed using Bluetooth or WiFi. TIP As a best practice, customer presets should be documented prior to performing any update in the event these settings are lost during the update.
