Description
B.U.D.S. (version 21/22/25) for vehicles 1996-2010 supports three communication protocols: The DESS®, 947-DI, Kw2000 and cannot determine by itself which protocol must be used for communicating with a particular module. It is the user who decides when to choose DESS, when to choose 947-DI or when to choose Kw2000 . If you try to communicate with a vehicle using the wrong protocol, B.U.D.S. will simply consider that the module is not present.
Choosing DESS protocol
For VCK:
Using this protocol requires that you connect one end of the DESS adapter in the 6-pin adapter and the other end on the DESS post of the vehicle or, on some vehicles, that you connect the 6-pin adapter directly into the diagnostic connector of the vehicle.
For MPI-2/MPI-3:
Using this protocol requires that you connect one end of the DESS adapter in the 6-pin connector of DESS Post Interface and the other end on the DESS post of the vehicle or, on some vehicles, that you connect the DESS Post Interface directly into the diagnostic connector of the vehicle.
