Principles of Operation

PRINCIPLES OF OPERATION

The roof opening panel assembly uses an integrated motor and module to operate the roof opening panel. The roof opening panel motor and module are installed new as an assembly. The roof opening panel is an electronically operated glass 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 motor/module. The soft-stop function is controlled by the roof opening panel motor/module. The roof opening panel has 4 modes of operation, manual mode, one-touch open, one-touch close and tilt. The one-touch open feature is activated when the open switch is pressed to the second detent. The one-touch close feature is activated when the close switch is pressed to the second detent. The tilt feature is activated when the tilt switch is depressed. These functions are controlled by the roof opening panel motor/module.

The roof opening panel has a comfort stop position, which is 70 mm (2.75 in) from the full OPEN position, and is controlled by the roof opening panel motor/module. The comfort stop position reduces wind rumbling noise that may occur when the vehicle is operated with the roof opening panel in the full OPEN position.

When the roof opening panel is opened in either one-touch open or manual mode, it will stop at the comfort stop position first. In manual mode, the roof opening panel can be opened to full open from comfort stop by releasing the switch, then pressing and holding it until the roof opening panel is in the full OPEN position. In one-touch open mode, the roof opening panel can be opened to full open from comfort stop by momentarily pressing the switch.

The roof opening panel can be closed either by pressing the close switch to the second detent (one-touch close), or by pressing and holding it until the roof opening panel is in the desired position.

A new roof opening panel motor will only open and must be initialized. The roof opening panel motor initialization procedure must be done when repairs are carried out on any part of the roof opening panel system, including: any time the roof opening panel motor has been removed from the roof opening panel assembly, a new roof opening panel motor has been installed or when a new roof opening panel assembly has been installed.
