Software FAQ

QUESTION: Does the VAD Pro-901 work on more cars than just VW/Audi?

ANSWER: The VAD Pro supports many different diagnostic protocols (J-1850, including PWM and VPW, ISO-9141-2, ISO-14230, and ISO-15765, covering nearly any European, Asian, or Domestic vehicle. The VAD Pro connects to engine and emissions sensors only, while other generic tools may connect to ABS, Airbag, and other “Body” and “Chassis” related modules.

QUESTION: The VAD Pro’s Print Module uses infrared (IrDA) technology. Where do I find an IrDA compatible workshop printer?

ANSWER: IrDA adapters are available by contacting VAD directly, or one of VAD Pro’s distributors. More information on the adapters STS-300, STS-301, and STS-302 can be found here. These IrDA adapters act as a link between current shop laser printers and the VAD Pro’s print module. A list of common compatible printers is available here.

ANSWER: The VAD Pro performs Immobilizer I, II, and III functions (such as key coding), which cover most VW and Audi vehicles up to approx. MY2000. As for newer cars requiring key coding/programming, there are no aftermarket tools that can perform this function. For security reasons, key coding requires SKC information that is only available through authorized dealers via satellite uplink to the manufacturer.

QUESTION: How do I use the Vehicle List?

ANSWER: We have reserved the left and right ports for future expansion.

QUESTION: Does VAD have access to the GEKO online system and “guided fault finding”, like they do at the dealerships?

ANSWER: VAD Pro does not have access to this system. VW adopted the GEKO system (an online login to VW) for its factory tools (at certified dealers), to provide exclusive communications, a resource not available to aftermarket tools.

QUESTION: Does VAD software allow you to reset all learned values from a specific ECU to factory settings?

ANSWER: There is no method known in the VAD tool for reformatting a single ECU to factory settings. There is a function in the tool for clearing ALL learned values in the vehicle. It is part of the “collection services” menu. This function clears all fault codes and learned values in every module.

QUESTION: Which VW/Audi models will VAD communicate with?

ANSWER: VAD can connect to all VW/Audi vehicles from the earliest OBD-I cars (circa 1990) to the latest 2010 models. A limited amount of the newer VW/Audi vehicles have only partial compatibility with VAD Pro at this time. VAD is working on a solution for these cars, and should have a software update resolving any compatibility issues soon.

Troubleshooting FAQ

QUESTION: I am having a difficult time establishing communication between the VAD Pro and a vehicle. What can I do?

    Exit the VAD application you are using.
