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

Component Identification:

Function
When the air recirculation switch (N22s2) on the AAC [KLA] control and operating unit (N22) or the air recirculation switch (N22/7s2) on the comfort AAC control and operating unit (N22/7) is actuated, the tilting/sliding roof can be closed. The position of the tilting/sliding roof last moved to is stored in the overhead control panel control unit (N70). 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, during closing, an opening operation is started via the air recirculation switch (N22s2) on the AAC [KLA] control and operating unit (N22) or with the air recirculation switch (N22/7s2) on the comfort AAC control and operating unit (N22/7), the tilting/ sliding roof reverses immediately.

Abortion of function
^ Function requirements not satisfied
^ manual actuation of left front power window motor or right front power window motor or left rear power window motor or right rear power window motor in any direction (function interruption only at corresponding power window motor).
^ Zero point tolerance exceeded
^ lock-up recognized by overhead control panel control unit (N70)
^ Actuation request is rescinded
^ Failure of message via interior CAN (CAN B)

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