Function
The control unit for seat adjustment powers the
positioning motors in the seat directly using its load
outputs. The position detection function of the
positioning motors is implemented using hall
sensors. The driver’s-side door control unit reads in
switch information from the operator unit for
memory, driver’s seat E97 as voltage-coded
information and sends this via CAN Convenience to
the control unit for seat adjustment with
steering-column adjustment memory J136.
The control unit for seat adjustment with
steering-column adjustment memory reads in
information from the switch for fore-and-aft and
height adjustment, driver’s seat E61, the switch for
backrest adjustment, driver’s seat E96 and the
switch for tilt adjustment, driver’s seat E222 directly.
The driver’s-side door control unit J386 reads in the
button information "Seat memory emergency-Off"
and supplies this discretely as well as in the form of
a CAN Convenience message to the control unit for
seat adjustment with steering-column adjustment
memory J136. Comfort functions, such as seat
symmetry positioning and comfort side view as well
as radio code allocation to a memory location, are
implemented using settings in the Multimedia
Interface (MMI).
