GF77.20-D-2043H Automatically Close Rear Sliding Roof Unit, Function

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

Function requirements:
- Circuit 15R ON
- Rear tilting/sliding roof (M12/1) normalized
- The DBE control unit (N70) recognizes the park position of the tilting/sliding roof control button (N70s1) for t = 50 ms before it is actuated again
- No overvoltage or undervoltage
Overvoltage is present when voltage > 16.5 V. Undervoltage is present when voltage < 9 V.
The function "Automatically close rear tilting/sliding roof" is limited.Requests via the transmitter key are still possible, because it is a manual function.

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

Sliding roof automatic closing, function

The rear tilting/sliding roof motor is actuated via the DBE control unit by momentarily pressing the tilting/sliding roof control button toward the front beyond the pressure point and the sliding roof is automatically moved to the closed position.

If the tilting/sliding roof control button is actuated in any direction, the actuation of the rear tilting/sliding roof motor is interrupted and 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.

tilting roof automatic closing, function

The rear tilting/sliding roof motor is actuated via the DBE control unit by momentarily pulling the tilting/sliding roof control button downward beyond the pressure point and the tilting roof is automatically moved to the closed position.

If the tilting/sliding roof control button is actuated in any direction, actuation of the rear tilting/sliding roof motor is interrupted and the tilting roof remains 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.

Obstruction

After obstruction is recognized by the excess force limiter, 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.
