| Control module, window lift, rear, RH (575RR), CV |
| Main purpose |
The primary function of the RRDM is to control and supply the rear right-hand window lift (with optional pinch protection function).
The RRDM also has logic for the door mirror heater. The activation command is transmitted on the bus.
| Type |
Internally there is a microprocessor with clock, RAM and a flash EPROM. An internal bus which connects the processor and memory with the I/O unit. The I/O unit is responsible for reading in the values of A/D converted analogue inputs, digital inputs, bus signals and for activating transistors in the output amplifier.
For further information about the control module see control module, general description .
