B.U.D.S. > MPI > Choosing a Protocol

[Natali]

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.

B.U.D.S. (version 3.3.0/3.8.2) for SeaDoo, SkiDoo/Lynx vehicles since 2007 and all Can Am* vehicles supports Kw2000 (Auto) communication protocol only.

The necessary protocol and diagnostic equipment for your vehicle can be determined from the table BUDS Chart .

 

To choose DESS protocol

1.	Select Choose Protocol from the MPI® menu.

2.	Select DESS from the Choose Protocol sub-menu.

3.	Wait few seconds while B.U.D.S. loads the protocol into the MPI.

4.	Verify that the status bar communication icon indicates DESS:

 

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.

If you communicate with a 947-DI using the DESS protocol instead of the 947-DI protocol, then the Monitoring, Activation, Faults and History pages will not be available.

To choose 947-DI protocol

1.	Select Choose Protocol from the MPI® menu.

2.	Select 947-DI from the Choose Protocol sub-menu.

3.	Wait few seconds while B.U.D.S. loads the protocol into the MPI.

4.	Verify that the status bar communication icon indicates 947-DI:

The 947-DI protocol is used to diagnose a vehicle equipped with a 947-DI engine.

For VCK®:

Using this protocol requires that you connect the 6-pin adapter directly into the diagnostic connector of the vehicle.  You can not use this protocol with the diagnostic cable connected on the DESS® post of the vehicle.

For MPI-2/mpi-3:

Using this protocol requires that you connect the DESS Post Interface directly into the diagnostic connector of the vehicle.

 

To choose Kw2000 protocol

1.	Select Choose Protocol from the MPI® menu.

2.	Select Kw2000 from the Choose Protocol sub-menu.

3.	Wait few seconds while B.U.D.S. loads the protocol into the MPI.

4.	Verify that the status bar communication icon indicates Kw2000:

The Kw2000 protocol is used to diagnose some personal watercrafts and snowmobiles.

 

For VCK:

Using this protocol requires that you connect the 6-pin adapter directly into the diagnostic connector of the vehicle.  You can not use this protocol with the diagnostic cable connected on the DESS® post of the vehicle.

For MPI-2/MPI-3:

Using this protocol requires that you connect the Diagnostic Cable directly into the diagnostic connector of the vehicle.

 

The Kw2000 (Auto) protocol is used to diagnose all modern BRP vehicles.

Only the MPI-2/MPI-3 Interface supports this protocol.

Using this protocol requires that you connect the Diagnostic Cable directly into the diagnostic connector of the vehicle.

 

Note

Upon startup, B.U.D.S. chooses the protocol that you were using when you terminated your last session.
