Main purpose

The primary function of the RRDM is to:

• Read the status of the door lift buttons
• Control and supply the window lift in the RH rear door (with optional pinch protection function).
• 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.

The RRDM also has logic for the front door mirror heating. The activation command is transmitted on the bus.
