Seats with three-point seat belt integrated in the backrest are installed in the cabriolet. If the seat backrests are
not locked correctly, in the event of an accident there is the danger that the occupants move forward with the
backrests with no restraint.
The seat modules monitor the seat backrest to ensure they are locked correctly. Hall sensors are installed in the
seat backrests for this purpose.
>
E64
The seat modules send messages on the K-bus to the centre console switch cluster (SZM) when the seat
backrests are not locked correctly. The SZM is the data interface (= gateway) to the K-CAN. The SZM
processes the message (check control message).
>
E93
If the backrests are not correctly locked, the seat modules will emit messages on the K-CAN.
