The power sunroof system consists of a front sliding glass panel and rear stationary glass panel which allows additional sun light and/or ventilation into the interior of the vehicle. The front sunroof glass panel tilts upward at the rear for the ventilation position or tilts down and slides rearward beneath the fixed glass panel for the open position. The system also includes a power sunshade which can be closed when additional sun light is not desired.
The power sunroof system allows the sunroof to be 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 power sunroof system features express operation (press & release switch) convenience feature that will automatically open or close the sunroof or sunshade. In addition the power sunroof system also features an obstacle detection feature which automatically reverses the sunroof or sunshade when it encounters an obstacle within the roof opening during express close operation.
The power sunroof system glass panels interface with the body roof opening flange with rubber seals to prevent wind noise and minimize water intrusion when the sunroof is closed. The sunroof system features a water management system that collects any water that leaks passed the sunroof seals and drains it safely outside the vehicle through drain hoses connected at all four corners of the sunroof frame.
The power sunroof system features a wind deflector that automatically deploys when the sunroof is opened to help minimize wind buffeting and wind noise. Wind buffeting is a pressure pulse that may be heard when driving with sunroof open and side windows closed.
The main components of the power sunroof system are:
- Fixed Rear Glass Panel
- Sliding Front Glass Panel
- Frame and Mechanism
- Drain Channel
- Motor Assemblies
- Power Sunshade
- Overhead Switches
- Wind Deflector
- Drain Hoses
