Panorama Roof (Only XC60)
Vehicles equipped with panorama roof are equipped with two Sun Roof Modules (SRM) (4/33). The panorama roof is operated using the same switches as the roof hatch.
The switches are located in the same module as the front reading lamps.
The front Sun Roof Module (SRM) is located in front of the glass roof and operates the glass hatch. The rear Sun Roof Module (SRM) is located behind the glass roof and operates the headlining. The position of the panorama roof is determined by four hall sensors, two in each control module.
Both motors are directly connected to the switch and to the Central Electronic Module (CEM). Some signals that are intended for the rear motor are sent via the front motor, which in turn forwards the signals via LIN communication to the rear motor.
