Module, Power Sunroof (PSM): Description
The motor and electronic module units for the dual pane sunroof or sunshade are quite similar, but are not interchangeable. The dual pane sunroof and sunshade motor and module units are interchangeable and configure themselves to either sunroof or sunshade operation through a configuration pin in the sunshade connector of the sunroof wire harness. Each sunroof motor (5) is a reversible, 12-volt Direct Current (DC), permanent magnet motor with internal thermal protection.
The dual pane sunroof has two motor and electronic modules, each secured by three screws to the underside of the front sunroof frame member and concealed above the headliner. The motor to the left of center operates the sliding glass mechanism, while the motor to the right of center operates the power sunshade mechanism.
Each motor is connected mechanically to the sunroof or sunshade drive gear (4) through a right angle drive, gear reduction transmission (3). Each motor also is connected electrically to an on-board electronic control unit (2) that has an integral connector receptacle (1) that connects the unit to the vehicle electrical system through a dedicated take out and connector of the sunroof wire harness.
The sunroof motor or sunshade motor and electronic module units cannot be repaired. If ineffective or damaged, the entire motor and module unit must be replaced.
