Convenience opening of tilting/sliding roof function

Function prerequisites

 no overvoltage/undervoltage

 circuit 15 off and

 circuit 15R off and

 circuit 15C off.

Function

The overhead control panel control module (N70) receives over CAN the request for convenience opening and then actuates the tilting/sliding roof motor (M12/1). The direction in which the motor is actuated depends on whether the sliding roof or the tilting roof is open. If the tilting/sliding roof is closed, then the sliding roof is opened. The motor is actuated until the overhead control panel control module (N70) via the position measurement detects

-----------------------------------------------------------------------------------------

that the sliding or tilting roof is completely open. The convenience opening function of the tilting/sliding roof is only available in the normalized state.

Exception: if the convenience closing function of the tilting/sliding roof was interrupted by lock-up, the overhead control panel control module (N70), after the request for convenience opening, moves the tilting/sliding roof back so that the lock-up is canceled again (emergency opening).

The convenience opening function of the tilting/sliding roof is aborted if

 the request over CAN is no longer received or

 lock-up of the tilting/sliding roof is detected or

 the function requirements listed above are no longer satisfied.
