Door Modules

Each door contains a door module (1) for the control of all functions contained or attached to the door. The door module is located inside of the door attached to the inner door carrier.

The door modules receive the signals for locking and un-locking requests from the CAS over the K-CAN-P.

The door modules are also responsible for interpreting the signals from the hall sensors in the door lock assemblies and providing them to the CAS.

The output for the ZV drives is controlled by internal final stages.

Each door contains a door module for the control of all functions contained or attached to the door. The door module is located inside of the door attached to the inner door carrier.

The door module receives the control requests from the window switches and carries out the allowed operation of the motor. The control is based on the status signalled from the CAS and the current condition of the window as detected by the hall sensors in the motor assembly.
