GF77.20-P-2016T Tilting/Sliding Roof Convenience Opening With Recirculated Air Button, Function
- with CODE (414) Power glass tilting/sliding roof

Component Identification:

Function requirements
^ Circuit 15 "ON"
^ Tilting/sliding roof normalized
^ No undervoltage or overvoltage
^ Previously close tilting/sliding roof via recirculated air switch

Function
When 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 SR motor (M12m1) is actuated in the opening direction until the previously stored position is reached.

If "Closing" via the air recirculation switch is initiated again during the "Opening" sequence before the stored position is reached, then the initially stored opening position is retained.

Aborting the function
^ Denormalization of tilting/sliding roof
^ Actuating tilting/sliding roof
^ Blockage detection
^ Failure of CAN message (CAN = Controller Area Network).
^ Actuation of excess force limiter

When the tilting/sliding roof is opened with the recirculated air switch, the windows are also opened in the previously stored position.
