Functional Procedure: Locking

The vehicle can only be locked once the footwell module has evaluated the door contacts and the Car Access System 4 has reported that the driver's door is closed.

The further signal progression for locking the vehicle corresponds analogously to the signal progression of the unlocking procedure.

During the vehicle locking process, all central locking drives are moved into the "Lock" position. The central-locking drives in the doors are additionally moved into the "centrally-locked" position. Following the central arrest procedure, the locking buttons in the doors are mechanically separated from the central locking drive system.

The vehicle can now no longer be unlocked using the locking buttons in the doors.
