- with CODE (242) Electrically adjustable front passenger seat with memory

Function conditions

- Normalized front passenger seat

Function
The scope of the functionality is integrated in the rear SAM control unit (N10/8). The microswitch access aid for the 2nd seat row, right (S159/1) is monitored by the rear SAM control unit.

If the access aid microswitch is closed by releasing the backrest, the rear SAM control unit transmits a message to the front passenger front seat adjustment control unit with memory (N32/2) and the instrument cluster (A1) via the CAN-B.

If at the time of release the Controller Area Network bus Class B (interior) (CAN-B) is in bus idle, then it is woken up by the rear SAM control unit.

If the position of the front passenger seat is preventing the seat in the second seat row from being folded and the seat occupied recognition detects that it is unoccupied, the front passenger seat is moved forward by the front passenger front seat adjustment control unit. If the armrest in the second seat row has been released, then the instrument cluster shows a corresponding message at circuit 15R ON.

As soon as the seat in the 2nd seat row has been locked again (microswitch open), the relevant message is placed on the CAN-B by the rear SAM control unit.

If the CAN-B is in bus idle when the locking takes place, it is awakened by the rear SAM control unit.
The display extinguishes in the instrument cluster.
