GF77.20-D-2044H Manually Open Rear Sliding Roof Unit, Function

- with CODE (D24) Power tilting/sliding roof, passenger compartment

Function requirements:
- Circuit 15R ON
- Before is actuated again, the DBE control unit (N70) recognizes the park position of the tilting/sliding roof control button (N70s1) for t = 50 ms
- No overvoltage or undervoltage
Overvoltage is present when voltage > 16.5 V. Undervoltage is present when voltage < 9 V.
Only the manual functions of the rear tilting/sliding roof (M12/1) are available in the denormalized state

Activation is accomplished by actuating the tilting/sliding roof control button up to the pressure point

The rear tilting/sliding roof motor is actuated via the DBE control unit by pulling and holding down the tilting/sliding roof control button toward the rear to the pressure point (M12/1m1) and the sliding roof is moved manually to the end position. When the tilting/sliding roof control button is released, the sliding roof remains in the current position. The sliding roof is in the closed position at the front stop and in the end position at the rear stop.

The rear tilting/sliding roof motor is actuated via the DBE control unit by pressing and holding down the tilting/sliding roof control button upward up to the pressure point () and the tilting roof is moved manually to the tilting position (ventilation position). If the tilting/sliding roof control button is released, the tilting roof remains in the current position.

In the closed position, the tilting roof is located at the front stop, in the tilting position (ventilation position) it is located at a defined position between the front and rear stops.

The tilting/sliding roof control button must be actuated for t > 50 ms. If the DBE control unit recognizes that the tilting/sliding roof control button is actuated for ≥ 25 s, the actuation of the rear tilting/sliding roof motor is deactivated and an error is stored. When the tilting/sliding roof control button is actuated again, the DBE control unit must previously recognize the park position of the tilting/sliding roof control button for t = 50 ms.

Lock-up

After lock-up is recognized, the rear tilting/sliding roof reverses directions, e.g. the rear tilting/sliding roof motor is actuated in the opposite direction and is deactivated after t = 160 ms.

Emergency operation

The position is not sensed if the rear tilting/sliding roof is actuated with the emergency operation It is then necessary to "normalize" the rear tilting/sliding roof.

Roller sun blind, function

The roller sun blind can be moved toward the front or rear using the handle mounted on the roller sun blind. The roller sun blind remains in the corresponding position. The roller sun blind is automatically rolled up.
