Single SAM (Z3L)
In vehicles with code (Z3L) the sensor and actuator
module, cab (SCA) control unit (A7) and the sensor
and actuator module, chassis (SCH) control unit
(A8) are replaced by the single signal acquisition
and actuation module (SSAM) control unit (A7a).
The single SAM is connected to the exterior CAN
(CAN 1) and interior CAN (CAN 2) bus systems.
Information is distributed across the bus systems
by the central gateway (CGW) control unit (A2).
The SSAM is located in the electronics compart-
ment on the passenger side in place of the SCA.
The function of the modular switch panel (MSF) is
integrated in the SSAM. The integrated MSF module
is liked directly to the switch modules over the LIN
bus.
