ISAT Communication

Data link connector





To and including M94 the car is fitted with two data link connectors, located below the passenger seat. One green and one black 10 pole data link connector. The electrically operated seat with memory is connected to the green socket.

M95 models are equipped with a 10 pole data link connector, located under the passenger seat.

On the M96 cars there is a 16 pole data link connector, located under the face by the steering column assembly.





Communication

To and including M95 the electronic control module for the electrically operated seat with memory and the ISAT scan tool communicate via two cables, the K and L cables.

The communication is single directional. The ISAT scan tool sends initiatives and commands via the L cable and the electronic control module responds via the K cable.

The stud lining is on the data link connector:

K L

Front left-hand seat Pin 1 Pin 5
Front right-hand seat Pin 1 Pin 6

Important: On the current M96, when the new electronic control module is introduced, the electronic control module communicates via a bi-directional K cable. The data link connector K cable is pin 8.

Before the introduction of the M96 the old electronic control module remains in production. The bi-directional communication system requires two pins at the data link connector, K cable is pin 8 and I cable is pin 11.
