The personal computer offers a comfortable user interface for diagnostics and can also include an extensive information system such as Vivid. The advantage of the TSPro diagnostic device is the combination of the advantages of a portable scan tool and a personal computer. TSPro has a display and a simple keyboard – so it can be diagnosed even in harsh environments or off-road without a personal computer. After connecting TSPro to a personal computer, all diagnostic functions can be performed using the software provided with TSPro. In this configuration, TSPro is used as an adapter between the control unit and the personal computer.
