The controller (CON) is only fitted in the 1 Series and 3 Series as of E87 depending on the variant.
The controller is available as a basic version and as a high version.
The high variant of the controller is fitted in vehicles with CCC.
The high variant has a motor that can create variable rotational resistance on the control button. The rotational resistance (e.g. end stop, detents) is controlled by the CCC.
The high version can distinguish 8 shifting directions on the control button. The 4 diagonal directions are only used for the navigation system.
The basic version of the controller is fitted in vehicles with M-ASK.
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.
The controller is supplied across the following cables:
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 motor of the control button of the high version is controlled via the K-CAN. The sender of this CAN message is the CCC.
The button illumination is activated controller by the controller. For activation, the controller uses the CAN message of terminal 58g (comes from FRM).
