GF77.20-P-2017T Tilting/Sliding Roof Convenience Closing With Recirculated Air Button, Function
- with CODE (414) Power glass tilting/sliding roof

Component Identification:

Function conditions
^ Circuit 15 "ON"
^ Tilting/sliding roof normalized
^ No undervoltage or overvoltage

Function
The tilting/sliding roof is closed by actuating the air recirculation switch (N22s2) (except code (581) Comfort automatic air conditioning) or air recirculation switch (N22/7s2) (with code (581) Comfort automatic air conditioning). The position last moved to is stored. When the recirculated air mode is completed the sliding roof or power windows move back to this stored position. However, this is only accomplished, when the tilting/sliding roof is not actuated manually during the recirculated air mode.

If an opening operation is started with the recirculated air switch while closing, the SR motor reverses directions immediately. M12m1

Function abort
^ Denormalization of tilting/sliding roof
^ Manual actuation of tilting/sliding roof
^ Blockage detection
^ Failure of CAN message (CAN = Controller Area Network).
^ Actuation of excess force limiter

When closing the tilting/sliding roof via the recirculated air switch the windows are also closed and their positions are stored.
