General information
Initialization of the slide/tilt sunroof
After the following service tasks, an initialization of the slide/tilt sunroof must be carried out:
- Replacement of the SHD control module
- Repairs on the mechanical system of the slide/tilt sunroof (e.g. slide/tilt sunroof was moved mechanically using the emergency actuating unit or replacement of the electric motor of the slide/tilt sunroof)
- Other repairs (e.g. replacement of a glass sunroof)
The initialization serves to adapt the anti-trapping protection to the slide/tilt sunroof.
IMPORTANT:
anti-trapping mechanism not active
The anti-trapping mechanism is not active during initialization.
The initialization procedure is divided into the steps 'standardization and 'learning the characteristic curves'.
- During standardization, the end stop of slide/tilt sunroof towards "Lift" is learned. The SHD control module uses this to calculate the end stops for opening and closing.
- When the characteristic curves are learned, the mechanical closing forces in the slide/tilt sunroof are recorded.
Comply with the following sequence for the initialization:
- Terminal 15 ON
- Press the slide/tilt sunroof switch forwards up to the resistance point towards "Close" (do not press beyond the resistance point) and hold pressed.
NOTE:
Press and hold down the slide/tilt sunroof switch.
If the slide/tilt sunroof switch is let go during initialization, the sequence must be repeated.
- After approx. 15 seconds, the operation starts automatically. The 2 glass sunroofs are raised. The electric motor continues to run until the end stop for the "Lift" position has been found.
- Thereafter, the slide/tilt sunroof is opened up to the end stop and closed again.
- After the slide/tilt sunroof has been closed again and the electric motor has switched off, the slide/tilt sunroof switch can be released. After approx. 2 seconds, required for data storage, the slide/tilt sunroof can be operated again using the slide/tilt sunroof switch.
