Sunroof / Moonroof Position Sensor: Description and Operation

Sunroof Motor With Control Unit





The drive for the sunroof is provided by a motor which is controlled by the integrated control unit. This assembly is mounted in front of the roof area between the roof liner and the lower section of the sunroof frame.

The control unit has a 13-pin connector that provides the connection between the wiring harness, the switch and the K-bus.

Two sensors (Hall sensors) are integrated in the motor/control unit for position recognition. When the motor is running, the control unit continuously monitors the sensors.
