Opening sliding roof, function - GF77.20-P-2004GH
MODEL 163 with CODE (414a) Electric glass sliding/pop-up roof
Function prerequisites
- Voltage not too low or too high
- Switch-on conditions for convenience control fulfilled
- Sliding/pop-up roof synchronized
Function
There are two methods for opening the sliding roof:
- Infinite positioning
When the sliding/pop-up roof switch (S13/2) is actuated continuously, circuit 30 is switched through to the sliding/pop-up roof motor (M12) , the sliding roof opens and can be positioned infinitely.
- Sliding roof express open feature
When the switch (SHD, S13/2) is actuated momentarily (< 0.3 s), the electronic evaluation circuitry actuates the motor until the end position "Sliding roof open" is recognized by the position measurement feature .
If the sliding/pop-up roof is desynchronized, it moves only in the pop-up roof direction each time the sliding/pop-up roof switch (SHD, S13/2)
is actuated. This means that it is possible to move to the zero position for synchronizing.
After successful synchronization , the sliding/pop-up roof can be controlled again without limitation.
Vehicles up to 11.99:
The power for the sliding/pop-up roof (M12) is supplied via a fuse directly to c. 30.
The power for the switch (SR, S13/2) is supplied via the convenience relay (F1k14) , which is actuated by the all-activity module (AAM, N10).
Vehicles as of 12.99 :
The power for the sliding/pop-up roof (M12) is supplied via a fuse directly to c. 30. The power for the switch (SHD, S13/2) is supplied via a lead to the extended-activity module (EAM, N10/1) , this power is switched through only when the switch-on conditions for the convenience control are fulfilled and the EAM is coded accordingly.
