Control Unit For Electronic Selector Lever Module, Task

The electronic selector lever module control unit (N15/5) receives digital and analog input signals, converts theses 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 position 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.

Input signals:

• Transmission Mode Switch (S16/5)
• Voltage Supply (Circuit 87)

Via CAN-C there is connection to:

• Instrument Cluster (A1)
• ME-SFI Control Unit (N3/10) Or CDI Control Unit (N3/9)
• ETC Control Unit (N15/3)
• ESP & BAS Control Unit (N47-5)
• EIS [EZS] Control Unit (N73)

ETC [EGS] Control Unit (N15/3):

• Selector Lever Position
• Transmission Mode Switch (S16/5)
• R/P-Restraining Magnet Energized
• Kickdown

Electronic Ignition Switch Control Unit (N73):

• Selector lever position for actuation of backup lamp.
