Location

The electronic selector lever module control unit is located in the center console.

Task

The electronic selector lever module control unit records the driver's shift requirements.

The following selector lever positions are possible

Park position "P"
Reverse gear "R"
Neutral "N"
Transmission mode "D" (automatic mode)
Manual shift mode "±"

If the selector lever is in "R" the left backup lamp (E3e3) and right backup lamp (E4e3) is actuated directly directly by the electronic selector lever module control unit.

If the selector lever is moved out of the transmission mode to the left in the "±" plane, manual shift mode is active. In the process the gears are shifted manually by the driver:

"+" one gear is upshifted

"-" one gear is downshifted

The shift lock button must be operated for the following shift operations:

from "P" to "R"
from "N" to "R"
from "R" to "P"

The shift positions are detected in the electronic selector lever module control unit via Hall sensors and read in and evaluated by the electronics within the electronic selector lever module control unit. The signals corresponding to the shift lever positions are passed on via the Controller Area Network (data bus/CAN bus) (CAN) to the automated manual transmission control unit (N15/6).

The selector lever module control unit locks or releases the mechanical park lock via a cable. The mechanical park pawl is locked if the selector lever is in "P".
