The main element of all of our Vehicle Server based diagnostic systems are the Vehicle server software modules. Residing on the Vehicle server itself, there is one software module for each vehicle system covered by our equipment. The licenses that allow each of the software modules to run, can be purchased separately, although in the case of the later CAN Bus based Vehicles, one License actually allows all of the modules applicable to the whole vehicle model to run. This price list however gives packages of multiple module licenses that have been grouped according to type. These represent something of a saving over buying the modules individually.
