Power Top/Sunroof (Service Information): Description

The information and procedures found in this service information cover only the electric motor, electronic module and the switches used for the sunroof. The information covering the mechanical components of the sunroof system can be found in the appropriate service information. Refer to SUNROOF, DESCRIPTION .

The single pane sunroof consists of a moveable glass panel over the first row seating which allows additional sun light and/or ventilation into the interior of the vehicle. The system also includes a manual sliding sunshade which can be closed when additional sun light is not desired.

The single pane sunroof glass can be slide opened, closed or placed in the vent position electrically by actuating switches in the overhead console. The sunroof system receives battery feed through a fuse in the Power Distribution Center (PDC) and an ignition wire to determine vehicle ignition state. The sunroof will only operate when the ignition is set to ON/Run, Accessory or while the Accessory Delay system is active. The power sliding sunroof system does not communicate through Controller Area Network (CAN) Bus Circuit. Therefore, the power sunroof system cannot generate Diagnostic Trouble Codes (DTC's).

The single pane sunroof system features an express operation (press & release switch) convenience feature that will automatically open or close the sunroof. In addition the power sunroof system also features an obstacle detection feature which automatically reverses the sunroof when it encounters an obstacle within the roof opening during express close operation.

The single pane sunroof features a mesh fabric wind deflector which deploys when the glass is in a slide open position to minimize wind noise in the interior.

The electric motors operate the sliding glass panel through the use of mechanical drive cables, mechanical linkages and guides. For further mechanical information, refer to the Body section of this service information for additional information on these components.

The sunroof glass can be cycled to the following positions:

• Vent Position  - The sunroof glass panel tilts upward 35mm at the rear for the Vent position.
• Open Position  - The sliding sunroof glass tilts downward and slides rearward beneath the fixed glass panel.
• Closed Position  - The sliding glass panel seals flush with the roof in the closed position to eliminate wind noise.

The major components of the single pane power sunroof system include:

• Sliding Glass Panel  - Refer to SUNROOF, DESCRIPTION .
• Frame and Mechanism  - Refer to SUNROOF, DESCRIPTION .
• Motor  - The single pane sunroof motor assembly is secured to the center of the front frame member of the sunroof, between the outer roof panel and the headliner.
• Manual Sunshade  - Refer to SUNROOF, DESCRIPTION .
• Switches  - The single pane power sunroof switches are integral to the overhead console centered in the headliner between the windshield upper header and the front of the sunroof opening.
• Wind Deflector  - Refer to SUNROOF, DESCRIPTION .

The sunroof circuit is protected by a 25 amp cartridge fuse located in the Power Distribution Center (PDC).
