Functional description AAS
When activated, the AAS will continuously send out an ultrasonic signal via the transmitter.
The receiver gets this signal and leads it back to the AAS. AAS is now able to compare
actual reflections represented by the received signal to previous signals. Any change means
that something within the cabin has changed. A message is sent to the BCM.
The AAS can be switched off by pressing the “AAS Off” switch. A LED will indicate switchoff.

Functional description DMM
The DMM is together with the PMM (Passenger Mirror Module)
is connected to LIN bus 8 where the MSM (Memory Seat
Module) is the master.
The DMM is the switch that controls the mirrors, and the
commands for the desired (up/down, left/right or fold/unfold)
movement to the MSM via LIN 8 which then sends out the
command back on LIN 8 to the DMM&PMM which send out the
current to move the mirrors. The mirrors can also be activated
and be repositioned by the MSM from the stored position in the
MSM memory when the memory buttons on the driver seat is activated.
