Control unit for electronic selector lever module, task - GF27.19-P-5138-02NT
Transmission 722.9 in model 211, 219 except code (428) Steering wheel shift buttons
Shown on model 211 up to 31.5.04 with M113, with code (219) Distronic (DTR)
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
