Location 

The camera cover (KAB) control unit (N144) is located in the liftgate.

Task 

The camera cover (KAB) control unit (N144) controls the opening and closing of the camera cover.

For this, it complies with the following tasks:

Reading in of signals 

Signals are read in via the following connections:

Direct line 

The camera cover (KAB) control unit (N144) reads in the status of liftgate open switch, exterior operation, reversing camera/360° camera (S202) via direct line.

Interior CAN (CAN B) 

The following signals, among others, are read in via interior CAN (CAN B):

The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).

Evaluation of signals 

The signals that have been read in are evaluated by the integrated microprocessor and the corresponding components are then actuated.

Actuation of components 

The camera cover (KAB) control unit (N144) actuates the motor in the liftgate open switch, exterior operation, reversing camera/360° camera (S202) directly.

Output of signals 

The camera cover (KAB) control unit (N144) transmits the status of the camera cover over the interior CAN (CAN B).
