Shown with OM 642 

Task 

The electronic selector lever module control unit (N15/5) receives digital and analog input signals, converts these and 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 performed are recognized without contact using the opto-electronic switches. A photoelectric barrier is closed or interrupted each time the position of the selector lever is changed.

Internal input signals: 

• Selector lever position
• Transmission mode switch (S16/5)
• Touch button +/-
• Voltage supply

Internal output signals: 

• R/P locking solenoid
• Shift gate illumination (circuit 58d)

The following information is received via CAN-C:

Instrument cluster (A1) 

• Circuit 58 dimmed

ESP and BAS control unit (N47-5) 

• Wheel speed and direction, right rear
• Wheel speed and direction, left rear
• Set braking torque
