Main purpose

The primary function of the PDM is to:

• Read the status of the door lift buttons.
• Control and supply the window lift in the passenger door (with optional pinch protection function).
• Supply the passenger door mirror motor and mirror heating (with optional memory function and electrically operated retraction).
• Read the central locking button status and transmit the value on the bus.
• Supply the central locking system motor in the door, with or without theft security locking (TSL), and to read the status of the central locking system and the TSL and transmit the value on the bus.
• The control module also reads the door switch status via a direct connection but does not use the value. The connection is intended for future development.
• Supply the illumination of the door buttons.
• Supply the step in lighting which is mounted on the underside of the door
• The PDM is also included in the car's "immobilizing environment" and continuously transmits an ID number on the bus.
