Overview

The roof opening panel consists of the following:

The roof opening panel motor must be initialized when repairs are carried out on the roof opening panel system, including: any time the roof opening panel motor has been removed, the roof opening panel glass (front sliding or fixed glass) has been removed or adjusted, or if the roof opening panel frame has been removed.
Refer to: Power Roof Opening Panel Initialization (501-17 Roof Opening Panel, General Procedures).

The roof opening panel is an electronically operated glass panel that can be opened, closed or tilted (vent position) by the roof opening panel control switch and the vent switch. Actuating the switches supplies a signal to the roof opening panel motor/module. The front sliding glass panel and the shield (sunshade) use two integrated motors/modules that are serviced as assemblies. The roof opening panel has one-touch open and one-touch close features that are activated when the switch is pressed to the second detent on the glass open or close side of the switch (the sliding glass panel close switch acts as a vent switch when the glass is in the closed position). Additionally the shield (sunshade) switch has one-touch open feature that is activated when the switch is pressed to the second detent on the shield open side of the switch.

Vista Roof Panel Glass The roof opening panel system on this vehicle includes a fixed vista roof panel glass behind the front sliding glass panel. Any time this panel is removed or adjusted the front sliding glass panel will need to be initialized.

K Bus Communication There is a communication circuit (K Bus) between the roof opening panel motor and the shield motor that is only for communication between the motors and not for service diagnostics. If this circuit is opened or shorted the sunroof system will not operate. When the K Bus circuit is repaired, normal system function will return.
