How to operate in DA-Dongle J2534 mode?
1. Download the latest J2534 DLL software files from the Diagnostic Associates web site www.diagnostic-associates.com/download.htm and install these on the SDD laptop.
2. Connect the J2534 device to the vehicle OBDII connector (the device powers from the vehicle).
3. Connect the 12ft USB cable to the J2534 device and the other end to the SDD laptop.
4. The red vehicle power (PWR) LED will illuminate to show that the device is powered.
5. During communication with the vehicle the status (STS) LED will flash green.
6. The device interacts with the SDD diagnostic tool in the same way as the existing VCM.
Otherwise, this perhaps more personal, I took me a small commission on sales that help me to maintain servers, domains and work involved in having this online blog. Although not enough to keep this blog takes many hours of work per month, answer email to people seeking information to help, etc .. help is appreciated.
If you got everything right with the “USB to Serial” Vag com 12.12, then it should work when powered by the car.Please keep in mind that the car may also have some blown fuse, in many cases the OBD interface +12 volts are directly taken from the cigarette lighter, if that is gone OBD won’t work either.
