The main tasks of the PDM are:
|
•
|
Read the window lift button status ·
|
|
•
|
Control and supply power for the passenger door window lift (with optional pinch protection function)
|
|
•
|
Supply power to the driver door mirror motors and mirror heating (optional memory function and electrically-operated retraction).
|
|
•
|
Read the central lock button status and send the value on the bus.
|
|
•
|
Supply power to the central locking system motor in the door with or without TSL (Theft Security Locking), read the door switch and TSL status and send the values on the bus ·
|
|
•
|
The control module also reads the door switch status with an individual lead but does not use the value. The connection is intended for future development.
|
|
•
|
Supply power to door button lighting ·

The PDM has an external button for the door window lift. The button has the following positions:
|
•
|
Express up (pinch protection variant only)
