The controller (CON) is only fitted on the E70 depending on the variant.

Versions of the controller

On the E70, the controller is only in the basic version.

The basic version of the controller is fitted in vehicles with M-ASK or CCC.
The basic version has only a mechanical rotational resistance on the control button. This means that the control button always has the same rotational resistance (detents) and no end stop.
The basic version can distinguish 4 shifting directions.

Supply lines of the controller

The controller is supplied across the following cables:

• Earth lead
  
• Positive cable from terminal 30g
  
• K-CAN connection (K-CAN-High and K-CAN-Low)
  

Bus communication of the controller

The controller sends the status of the control button (shifting direction, detected rotation, button of the control button) and the status of the additional buttons via the K-CAN. The recipient of this CAN message is the CCC or M-ASK.

The button illumination is activated controller by the controller. For activation, the controller uses the CAN message of terminal 58g (comes from FRM).
