Sunroof / Moonroof: Description and Operation

ROOF OPENING PANEL

The roof opening panel consists of the following:
- air deflector
- overhead console
- roof opening panel
- roof opening panel motor
- roof opening panel module
- roof opening panel shield
- roof opening panel switch
- roof opening panel drain hoses

The roof opening panel is an electronically operated panel that can be opened or closed by depressing a switch located inside the vehicle on the overhead console. It also has a one-touch open feature.

The ones touch open feature is controlled by the roof opening panel module. When the switch is pressed and held for one second the roof opening panel will open to the comfort position (approximately 100 mm (4 in) from the full open). Pressing the switch a second time will open the roof opening panel to the full-open position.

The roof opening panel can be moved to the fully closed position by rocking the switch forward and holding it until the roof opening panel is fully closed.

When the roof opening panel is in the fully closed position, the rear portion can be raised to the vent position to provide ventilation by rocking the switch forward. The roof opening panel can be closed by rocking the switch rearward.

PRINCIPLES OF OPERATION

Roof Opening Panel
The roof opening panel is an electronically operated panel that can be opened or closed by the roof opening panel switch. Actuating the switch in either a forward or rearward motion supplies a ground to the roof opening panel module. The roof opening panel module supplies the power to the roof opening panel motor when the switch is depressed. The vent and soft stop functions are controlled by the roof opening panel module and an internal roof position switch within the roof opening panel motor. These positions are obtained when an internal motor cam opens the roof position switch removing the ground from the switch.
