Description And Operation: Operation: Notes

In the rear part of the sunroof there are two electric motors, with simple electronics, to manage the sunroof functions such as automatic opening and anti-pinch.

The BCM controls the intensity of the lighting for the switch panel on the front roof light. Depending on the position of the switch, an earth signal is sent to the electronic circuit of the blind or roof movement motor, to identify the type of command requested: opening, closing or swivel position (VENT).

The switch position signals for opening and closing, along with the vehicle speed signals, panel-operated supply +15 and direct battery supply +30 reach the electronic circuit of the two roof movement motors.

The electronic circuit installed on the sunroof movement motors manages, in addition to movement, the anti-pinch function. To do this they need to recognize the sunroof and blind limit switches.

Electric sunroof limit switch initialization procedure  - Following an automatic motion malfunction while opening/closing or an emergency maneuver, the automatic operation of the sunroof must be initialized again.

Proceed as follows:

• move the sunroof to fully closed position;
• move the ignition switch to STOP and keep it there for 10 seconds;
• bring the ignition switch to RUN;
• press the sunroof movement button to the CLOSE position;
• press the button for at least 10 seconds, then you should hear the mechanical stop of the sunroof motor;
• press the sunroof movement button to the CLOSE position again within 5 seconds;
• hold the sunroof movement button down: in this position, the sunroof will perform an automatic opening and closing cycle. Otherwise, repeat the operations starting from the beginning;
• hold the sunroof movement button down until the sunroof is completely closed: the initialization procedure has ended.
