Hyundai Genesis (DH): Rear Curtain System / Description and Operation

Description
The rear curtain is AUTO UP/AUTO DOWN by one-touch operation of the switch. The curtain covers the inner side of the rear glass to keep passengers out of direct sunlight.
The rear curtain system is built in BCM. If the symptom seems to have to do with the rear curtain operation logic, BCM needs to be inspected. In this case, refer to the GDS-using diagnosis procedures (input/output data monitoring, actuation test).
Main Features

When switching to the reverse gear, the rear curtain automatically rolls down. When the car is parked, the curtain returns to its original position.
