Camera Cover Control Unit, Component Description - GF54.65-P-5005RDM

Model 172.4 as of model year 2017 

with code 218 (Rear View Camera) 

Shown model 172 

Location 

The camera cover control unit is located under the rear bench seat on the left relative to the direction of travel.

Tasks 

The camera cover control unit controls the opening and closing of the rear camera cover. The cover protects the lens of the reversing camera from dirt caused by external influences (e.g. splash water).

The camera cover control unit has the following tasks:

• Reading in of sensors 
• Evaluation of input factors 
• Actuation of components 
• Output of signals 

Reading in of sensors 

The input factors are read in over the following connections:

• Direct line 
• Interior CAN (CAN B) 

Direct line 

The camera cover control unit reads in the signals from the rear camera cover motor switch (M35/2s1) directly.

Interior CAN 

The following information is read in via the interior CAN:

• Circuit 15 status
• Request to open/close camera cover

The functions that use these signals are described in the individual 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 relevant components are then actuated.

Actuation of components 

The camera cover control unit actuates the rear camera cover motor (M35/2) directly.

Output of signals 

The parking system control unit sends the status of the rear camera cover motor (flap position) via interior CAN.
