Power Sunroof - Description

DESCRIPTION

Two power operated sunroofs are available factory-installed optional equipment on this vehicle. One has a single sliding glass panel and is referred to as the Single Pane Sunroof. The other has two glass panels, one sliding and one fixed, and is referred to as the Dual Pane (also known as the CommandView(R)) Sunroof. The information and procedures cover only the electric motor and electronic module units and the switches used for these two sunroofs. The information covering the mechanical components of these two sunroof systems can be found in the Body system. Sunroof - Description.

SINGLE PANE SUNROOF

The single pane power sunroof system allows the sliding glass sunroof panel over the first row seating to be opened, closed or placed in a ventilation position electrically by actuating one of three switch push buttons located in the overhead console. The electronic controls integral to the sunroof motor and module unit provide an express (also known as one-touch) feature to simplify sunroof opening and closing while driving. The electronics also provide an Excess Force Limitation (EFL) feature, which detects obstacles trapped between the glass and the opening in the vehicle roof during closing.

The sunroof glass panel tilts upward at the rear for the ventilation position, or slides downward and rearward between the outer roof panel and the headliner for the open position. The glass panel seals flush with the roof in the closed position to eliminate wind noise, and an integrated mesh wind deflector reduces wind buffeting at low speeds with the sunroof open. The sunroof also includes a manual sliding sunshade to cover the deep tinted glass panel when closed.

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

- Frame and Mechanism - Sunroof - Description.
- Manual Sunshade - Sunroof - Description.
- Motor and Module Unit - The single pane power sunroof motor and module unit is secured near the center of the front frame member of the sunroof, between the outer roof panel and the headliner.
- Sliding Glass Panel - Sunroof - Description.
- Switch - The single pane power sunroof switch unit is integral to the overhead console centered in the headliner between the windshield upper header and the front of the sunroof opening.
- Wind Deflector - Sunroof - Description.

Hard wired circuitry connects the single pane power sunroof system components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the single pane power sunroof system components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.

DUAL PANE SUNROOF

The optional dual pane (also known as the CommandView(R)) sunroof has one movable deep tinted glass pane over the front row seating and one fixed deep tinted glass pane over the second row seating. This unit also features a power operated sunshade that extends over both the front and rear glass panes when closed. If one of the switch push buttons for the movable pane is actuated while the sunshade is extended over the front glass opening, the system will automatically retract the sunshade to behind the front glass opening before moving the sunroof glass pane. Therefore, the sunshade can never cover the movable glass pane opening unless the pane is in the fully closed position.

The dual pane power sunroof system allows the sliding glass sunroof panel to be opened, closed or placed in a ventilation position electrically by actuating one of three switch push buttons located in the overhead console. The electronic controls integral to the sunroof motor and module unit provide an express (also known as one-touch) feature to simplify sunroof opening and closing while driving. The electronics also provide an Excess Force Limitation (EFL) feature, which detects obstacles trapped between the glass and the opening in the vehicle roof panel during closing.

A second two push button switch in the overhead console provides separate express features for opening and closing the sunshade. The power operated sunshade electronics also provide an EFL feature, which detects obstacles trapped between the sunshade and the opening in the vehicle roof panel during closing.

The sliding sunroof glass panel tilts upward at the rear for the ventilation position, or slides downward and rearward beneath the fixed glass panel for the open position. The sliding glass panel seals flush with the roof in the closed position to eliminate wind noise, and an integrated mesh wind deflector reduces wind buffeting at low speeds with the sunroof open.

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

- Fixed Glass Panel - Sunroof - Description.
- Frame and Mechanism - Sunroof - Description.
- Motor And Electronic Module Units - The dual pane power sunroof and power sunshade motor and electronic module units are secured to each side of center on the front frame member of the sunroof, between the outer roof panel and the headliner.
- Power Sunshade - Sunroof - Description.
- Sliding Glass Panel - Sunroof - Description.
- Switches - The dual pane power sunroof and power sunshade 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 - Sunroof - Description.

Hard wired circuitry connects the dual pane power sunroof system components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the dual pane power sunroof system components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators.
