The control panels in the driver's door are directly connected to the driver door module (DDM). Driver door module (DDM) receives the input signals from the control panels. The control module then carries out the function or transmits the signal on using CAN and LIN communication to the control module which is carrying out the function.

The following functions can be controlled via the control panels:

• all power windows
• child-proof lock (only applies to S40/V50)
• all windows up/down (instead of child-proof lock) (only applies to C70)
• operating the door mirrors
• central locking.
