The left front door control unit supplies the connected control elements with c. 58d.

Interior CAN
The signals are read in by the left front door control unit via the interior CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).

Evaluation of input factors
The input factors that have been read in are evaluated by the integrated microprocessor and the affected components are then actuated.

Actuation of components
The actuation of the components takes place via the following connections:
^ Direct line
^ Interior CAN

Direct line
The following components are actuated via a direct line:
- Left front door central locking motor (A85m1)
