Internal CAN connection is needed and the software will tell you once the procedure is started and before the PIN can be verified. You will get the following message: “Please use an adapter to connect to internal vehicle CAN“

CB012 adapter is connected between the AVDI and the CB106 cable. The needle pinches are connected to the internal CAN wires of the vehicle - please check the technical documentation for the particular vehicle you are working with to be sure which are the CAN H and CAN L wires in your vehicle.

Below you can see an example of connecting the CB012 to a 2021 Nissan Qashqai J12’s UPC module. In this example the CAN H is the blue wire on the vehicle, and CAN L is the pink wire. Wire colors may vary, so you need to check the documentation of your own vehicle.
