Power Sunroof System Components
The power sunroof system is a tilt/slide style, consisting of the following
components:
| • | Sunroof actuator, control module included |
| • | The rail and track assembly upon which the sunroof window rides |
| • | Power supply for the sunroof actuator motor and Retained Accessory Power
(RAP) relay: SUNROOF 25 A fuse |
Power Sunroof Operation
The power sunroof will operate with the ignition switch turned to Accessory
or RUN. Once the ignition switch is turned to OFF, from RUN, the sunroof will continue
to operate until any door is open or when the Retained Accessory Power (RAP) has
timed out. For a complete description of the RAP operation, refer to
Retained Accessory Power (RAP) Description and Operation
in Retained Accessory Power.
Use the rocker type sunroof switch to command the sunroof to :
Pressing the sunroof switch rearward, the sunroof window will slide from:
| • | Vent position to the closed position |
| • | Closed position to the open position |
Pressing the sunroof switch forward, the sunroof window will slide from:
| • | Open position to the closed position |
| • | Closed position to the vent position |
To Slide Open
The slide open function will work when the sunroof window is in the closed or
partially open position. To slide open the power sunroof, press and hold the sunroof
switch rearward. This will apply an input to the sunroof actuator motor from the
sunroof switch open contacts through the sunroof switch open signal circuit. The
constant input, allows the sunroof actuator motor to control the opening of the sunroof
window. From the closed position the sunroof window will lower slightly, then slide
open, rearward, with the sunroof sunshade between the roof and the headliner, stopping
at the comfort stop position.
From the comfort stop position, an open request will slide the sunroof window
approximately (1 in) 2.54 cm further open. The next open request will
slide the sunroof window completely to the full open position.
To Close
To close the power sunroof from the:
| • | Open position -- press and hold the sunroof switch forward. This
will apply an input to the sunroof actuator motor from the sunroof switch close contacts
through the sunroof switch close signal circuit. The sunroof switch close input at
the sunroof actuator motor needs to be constant, switch pressed, allowing the sunroof
actuator motor to control the motor to drive the sunroof window forward, until it
reaches the closed position. To close the sunshade, this will have to be manually
slid closed. |
| • | Vent position -- press and hold the sunroof switch rearward. This
will apply an input to the sunroof actuator motor from the sunroof switch open contacts
through the sunroof switch circuit. The sunroof switch open input to the sunroof
actuator motor needs to be constant, switch pressed, to allow the motor to tilt the
sunroof window down to the fully closed position. |
To Vent Open
To open the power sunroof to the vent position from the closed position, press
and hold the sunroof switch forward. This will apply an input to the sunroof actuator
motor from the sunroof switch close contacts through the sunroof switch close signal
circuit. The sunroof switch close input to the sunroof actuator motor needs be constant,
switch pressed, to allow the sunroof actuator motor to control the motor to tilt
the rear of the sunroof window upward to the vent position.
Limit Switches
The limit switches are within the sunroof actuator motor and supply data. The
multiple data combinations allow the sunroof actuator motor to track the position
of the sunroof window.
Sunroof Actuator Motor
The sunroof actuator motor contains the logic and is serviceable as one unit.
