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:

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.
