This function allows users to make some app settings and manage VCI etc.
9.1 VCI Management
If several VCI devices are activated on this tool, a list of VCI devices will be
displayed on the screen. If your tool extends to support heavy-duty trucks, you
need to switch to the corresponding VCI module before diagnosing it.
Once you choose the device that belongs to other account, you have to log out,
and then input the right account to continue.
• If you use another VCI to test a vehicle, select the desired checkbox and tap
“Pair” to pair it with the tablet.
• If the current VCI comes across communication failure, tap “Firmware Fix” to
update and fix the diagnostic firmware. During fixing, please do not cut power
or switch to other interfaces.
• If you use the current account to test a vehicle with another tablet, tap
“Unpair” to unpair the VCI device with the previously paired tablet.
• If you bought a new VCI device or skipped the Activate VCI step in process of
sign-up, tap “Activate VCI” to activate it.
Input the Serial Number and Activation Code (can be found from the included
Password Envelope), and then tap “Activate” to activate it.
