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
- 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
