GF77.20-P-2022TX Tilting/Sliding Roof Rain Closing, Function
- with CODE (414) Glass electric tilting/sliding roof
- except CODE (494) USA version



Function requirements
^ Vehicle locked
^ Tilting/sliding roof opened in sliding roof position

Function
Tilting/sliding roof rain closing is actuated as follows:
^ Moistening of windshield is recognized by rain/light sensor (B38/2)
^ 12 h after the vehicle was locked last
^ The operating voltage or operating temperature is no longer within the range of the rain/light sensor

If the tilting/sliding roof is in the open sliding roof position when the vehicle is locked, the rain/light sensor is activated after 30s by the overhead control panel control module(N70) for rain closing.

If the rain/light sensor detects moisture on the windshield during monitoring, it wakes up the overhead control panel control module. The latter transmits the command "Close tilting/sliding roof, rain" to the rear SAM control module with fuse and relay module (N10/2) via passenger compartment CAN bus and activates automatically the command "Move tilting/sliding roof to tilting position".Then monitoring is no longer performed.

Function abort
The excessive force limitation is also effective during rain closing and reverses the direction of the tilting/sliding roof

When the excessive force limitation is actuated, the rain/light sensor is no longer monitored
