Component Identification:

Location
The steering wheel gear shifter MINUS is located on the left, the steering wheel gear shifter PLUS is located on the right on the back of the multifunction steering wheel (MFL).

Task
The steering wheel gear shifter MINUS and PLUS have the following tasks:
^ Preselection of shift range.
^ Shifting into a gear from which the vehicle can be favorably accelerated or decelerated.
^ Direct switching of all forward gears in manual program "M"

Function
The steering wheel gear shifter MINUS and PLUS are read in via the steering LIN by the steering column module (N80). The steering column module places the signal "upshift" from the steering wheel gear shifter PLUS or the signal "shift down" from the steering wheel gear shifter MINUS on the chassis CAN. The fully integrated transmission control (VGS) control unit (Y3/8n4) receives the signal via the ME control unit (N3/10) and triggers the gearshift operation.

Shifts, which would result in impermissibly high or low engine speeds, are not performed.
