N80 Steering column module

Location
The steering column module is located on the steering column.

General
For data exchange the steering column tube module is connected to the interior CAN (CAN B), drive train CAN (CAN C) and with the Local Interconnect Network (LIN).
Via LIN the communication takes place between the left multifunction steering wheel button group (S110) and the right multifunction steering wheel button group (S111) with the steering column tube module.

Functions
^ Control and data exchange for steering wheel heater (with code (VL0) Heated multifunction steering wheel)
^ Control of switch and controls illumination of the multifunction steering wheel button groups
^ Cruise control switch with variable speed limiter (S40/4) (without code (ZU8) USA version)
^ Voice control system switch (S93/2) (with code (EL1) LINGUATRONIC voice control system or code (EU1) COMAND, APS)
^ Multifunction steering wheel button groups

Reading in the following components:
^ Combination switch (S4)
^ Steering angle sensor (N49)
^ Steering column adjustment switch (S59) (without code (VL0) Heated multifunction steering wheel)
^ Steering column adjustment/steering wheel heater switch (S59/1) (with code (VL0) Heated multifunction steering wheel)
^ Cruise control switch (S40) (with code (ZU8) USA version)

Discrete inputs
^ Circuit 30
^ Circuit 31

CAN signals
The steering column tube module is a subscriber on the interior CAN and drive train CAN.
