The electronic selector lever module control unit (N15/5) receives digital and analog input signals, actuates various components or transmits information to various control units via the Controller Area Network bus class C (engine compartment) (CAN-C).

The selector lever positions and touch shifts carried out are detected in a non-contact manner by means of optoelectronic switches. A photoelectric barrier is closed or interrupted each time the position of the selector lever is changed.

Analog input signals:

Selector lever position
Transmission mode switch (S16/5)
Touch button +/-
Steering wheel gear shifter MINUS (S110/1) (models 230.474/479)
Steering wheel gear shifter PLUS (S111/1) (models 230.474/479)
Voltage supply (circuit 87)

Analog output signals:

R/P locking solenoid
Gate lighting (circuit 58d)

The following information is received via CAN-C.

Instrument cluster (A1):

Circuit 58 dimmed
